It is detachably fitted in the recess of the main body.

Hereinafter, the film-forming container of this embodiment will be described with reference to the drawings. In the present specification, the same elements may be designated by the same reference numerals in the description of the drawings, and duplicate description may be omitted.

FIG. 1 (a) is a perspective view showing an example of a film-forming container of this embodiment, and FIG. 1 (b) is an exploded perspective view of FIG. 1 (a). The film-forming container 1 has a filling portion 10 for filling a liquid or gel-like material, and the filling portion 10 has a bottom surface 10a and a side surface 10b. The bottom surface 10a of the filling portion 10 has a first region 11 and a second region 12 located at the end of the bottom surface 10a and adjacent to the first region 11, and the first region 11 and the second region 12 are separated. It is possible, and the film-forming container 1 has a main body portion 2 including a first region 11 and a separable portion 3 including a second region 12 and separable from the main body portion 2.

In the film-forming container 1, the main body 2 has a main body bottom 21 including the first region 11 and a main body wall 22 serving as a side surface 10b of the filling portion 10, and the main body bottom 21 is the first. A recess 23 is provided in a region other than the region 11, and the separating portion 3 is detachably fitted in the recess 23 of the main body portion 2.

The separation portion 3 has a separation portion base 31 including the second region 12, a separation portion wall portion 32 serving as a side surface 10b of the filling portion 10, and further has a grip portion 33.

Further, in the main body portion 2, the main body portion wall portion 22 has a notch portion 24 into which the grip portion 33 of the separation portion 3 is detachably fitted.

2 (a) to 2 (c) and 3 (a) to 3 (b) are process diagrams showing an example of a film forming method using the film forming container of this embodiment, and FIGS. 1 (a) to 1 (b). This is an example using the film-forming container shown in b). First, as shown in FIG. 2A, the boundary between the first region 11 and the second region 12 of the filling portion 10 of the film-forming container 1 in the longitudinal direction of the filling portion 10, that is, the bottom surface 10a of the filling portion 10a. The liquid or gel-like material is supplied in a direction orthogonal to the direction along the portion 13, that is, in the y-axis direction. Next, as shown in FIGS. 2A to 2B, the deploying means 52 such as a squeegee is placed in the lateral direction of the filling portion 10, that is, the first region 11 and the second region 12 of the bottom surface 10a of the filling portion 10. By moving the material along the boundary portion 13 of the above, that is, in the x-axis direction, the bottom surface 10a of the filling portion 10 is spread with a liquid or gel-like material, and the filling portion 10 is filled with the liquid or gel-like material. .. As a result, a liquid or gel-like material film 51b is formed. Then, the liquid or gel-like material film 51b is dried to form the film 51 as shown in FIG. 2C. Next, as shown in FIG. 3A, the film 51 is removed from the main body 2 by removing the separation portion 3 from the main body 2 in the direction indicated by the arrow in FIG. 2C, that is, in the diagonally upward direction. Peel off from. At this time, the separation portion 3 is removed from the main body portion 2 by holding the grip portion 33 of the separation portion 3. Subsequently, the separation portion 3 is peeled off from the membrane 51 to obtain the membrane 51 as shown in FIG. 3 (b).

When a liquid or gel-like material is formed using the film-forming container of this embodiment, the film-forming container of this embodiment is formed by having a separable part from the main body. The membrane can be easily peeled off from the membrane-forming container. Therefore, when the film is peeled off from the film-forming container, it is possible to prevent the film from cracking, breaking, wrinkling, or the like. Therefore, it is possible to improve the yield. Further, work efficiency can be improved.

Further, in the present embodiment, since the separating portion is detachably fitted in the recess of the main body portion, the main body portion and the separating portion can be easily combined, and the separating portion can be easily removed from the main body portion. It is possible to further improve work efficiency.

In addition, when a liquid or gel-like material is formed using the film-forming container of this embodiment, the filling portion is filled with the liquid or gel-like material to form a liquid or gel-like material film. In some cases, the height of the side surface of the filling portion, that is, the depth of the filling portion can be used to obtain a material film having a uniform thickness. Thereby, a film having a uniform thickness can be obtained. Therefore, it is possible to obtain a film having good smoothness.

Hereinafter, each configuration of the film-forming container of this embodiment will be described.

(1) Separation part The separation part in this embodiment is a member that includes a second region on the bottom surface of the filling part and is separable from the main body part. Further, the separating portion in this embodiment is detachably fitted in the recess of the main body portion.

As for the position of the separating portion, since the separating portion constitutes the second region on the bottom surface of the filling portion and the second region is located at the end of the bottom surface of the filling portion in the filling portion, the separating portion is formed. May be located at the end of the filling portion.

Further, the separating portion may be located at the end of the filling portion. For example, when the filling portion has a rectangular shape in a plan view, the separating portion may be located at any end of the filling portion. Specifically, when the plan view shape of the filling portion is a rectangular shape other than a square, the separating portion may be located at the end on the short side side of the filling portion, and the end on the long side side of the filling portion. It may be located in the section. In the examples shown in FIGS. 1A and 1B, the separating portion 3 is located at the end on the short side side of the filling portion 10.

The separating portion may include a second region on the bottom surface of the filling portion, can be separated from the main body portion, and can be detachably fitted into the recess of the main body portion. It can have a separation base that includes two regions. That is, the separating portion can have a separating portion base portion that constitutes a second region on the bottom surface of the filling portion.

The plan view shape of the separation portion base may be any shape as long as the separation portion can be detachably fitted into the recess of the main body, and can usually be the same as the plan view shape of the recess of the main body. It is appropriately selected according to the plan view shape of the concave portion of the main body. As the plan view shape of the separation portion base, for example, a rectangular shape can be mentioned.

The cross-sectional shape of the base of the separating portion may be any shape as long as the separating portion can be detachably fitted into the recess of the main body and the film can be peeled off without tearing at the time of peeling. It is appropriately selected according to the shape. For example, in the lateral direction of the separation portion base 31, that is, in the y-axis direction, that is, in the yz plane, the cross-sectional shape of the separation portion base 31 may be rectangular as shown in FIG. 4A. , As shown in FIG. 4B, it may have an inverted trapezoidal shape.

Regarding the thickness of the separation portion base 31, when the separation portion is fitted into the recess of the main body, for example, as shown in FIG. 4A, the depth of the first region 11 of the filling portion 10 and the thickness of the second region 12 The depths are the same, that is, the first region 11 and the second region 12 are flush with each other, or as shown in FIG. 4C, the depth of the first region 11 of the filling portion 10 is the second region. It is preferably set so as to be larger than the depth of 12. That is, as shown in FIG. 4A, the thickness of the separation portion base 31 is the same as the depth of the recess 23 with respect to the portion of the first region 11 of the main body bottom 21 in the main body 2, or FIG. 4 ( As shown in c), it is preferably larger than the depth of the recess 23 with respect to the portion of the first region 11 of the bottom portion 21 of the main body. In these cases, it is possible to prevent the film from cracking, breaking, wrinkling, etc. when the separated portion is removed from the main body when the film-formed film is peeled from the film-forming container.

The area of the base portion of the separation portion in a plan view is not particularly limited as long as the area is such that the separation portion can be easily removed from the main body portion when the film-formed film is peeled from the film-forming container. Above all, it is preferable that the area of the base portion of the separation portion in a plan view is such that the second region of the bottom surface of the filling portion is smaller than the first region of the bottom surface of the filling portion. That is, it is preferable that the area of the base portion of the separation portion in a plan view is smaller than the area of the portion of the first region of the bottom portion of the main body portion of the main body portion in a plan view. Since the film portion formed on the separation portion may not be used as a product from the viewpoint of cleanliness, for example, the area of the separation portion base in a plan view is the first region of the bottom portion of the main body portion of the main body portion. By making the area smaller than the plan area of the portion, waste of liquid or gel-like material can be reduced.
For example, the area of the base of the separation portion in a plan view varies depending on the size of the filling portion, but it should be 1/2 or less with respect to the area of the first region of the bottom of the main body of the main body in a plan view. Of these, it is preferably 1/8 or less, and more preferably 1/10 or less.

Further, the separating portion preferably has a grip portion. When a liquid or gel-like material is formed using the film-forming container of this embodiment, when the film-formed film is peeled from the film-forming container, the grip portion of the separation portion is held and the separation portion is formed. Can be easily removed from the main body. Therefore, the formed film can be more easily peeled off from the film-forming container. Therefore, when the film is peeled off from the film-forming container, it is possible to prevent the film from cracking, breaking, wrinkling, or the like. Therefore, it is possible to improve the yield. In addition, work efficiency can be improved. Further, when the film-formed film is peeled off from the film-forming container, the cleanliness of the film can be maintained by holding the grip portion of the separation portion and removing the separation portion from the main body portion. Therefore, the film-forming container of this embodiment can be used to form a film applied to various uses.

The grip portion can be a portion other than the second region of the separation portion. That is, the grip portion can be a portion other than the separation base portion.

The position of the grip portion is not particularly limited as long as the grip portion is located at a portion other than the base portion of the separation portion. Among them, for example, as shown in FIGS. 5A to 5E, the grip portion 33 is a boundary portion between the first region 11 and the second region 12 of the bottom surface 10a of the filling portion 10 in the longitudinal direction of the separation portion base 31. It is preferable that the components are arranged symmetrically with respect to the direction along the axis 13, that is, the x-axis direction. For example, in FIGS. 5 (a) and 5 (c), one grip portion 33 is arranged at a position symmetrical with respect to the x-axis direction, and in FIG. 5 (b), the grip portion 33 is arranged in the x-axis direction. Two are arranged symmetrically with respect to each other. By locating the grip portion in this way, a force can be uniformly applied to the film when the film is peeled from the film-forming container.
5 (a) to 5 (c) are schematic plan views showing an example of the separation portion in this embodiment, and FIG. 5 (d) is a sectional view taken along line AA of FIGS. 5 (a) to 5 (c). FIG. 5 (e) is a cross-sectional view when the separation portion shown in FIGS. 5 (a) to 5 (d) is fitted into the recess of the main body portion.

The shape of the grip portion in a plan view is such that when the film-formed film is peeled from the film-forming container, the grip portion of the separation portion is held and the separation portion can be easily removed from the main body portion. There is no particular limitation. Examples of the plan view shape of the grip portion include a rectangular shape and the like.

As the length of the grip portion in the longitudinal direction of the base of the separation portion, that is, in the direction along the boundary between the first region and the second region of the bottom surface of the filling portion, that is, in the x-axis direction, the film-formed film is used for film formation. When peeling from the container, the length is not particularly limited as long as the grip portion of the separation portion is held and the separation portion can be easily removed from the main body portion, and the position and number of grip portions are not particularly limited. It is appropriately selected according to. For example, the length of the grip portion in the x-axis direction can be equal to or less than the length of the separation portion base portion in the x-axis direction.

The length of the grip portion in the lateral direction of the base of the separation portion, that is, in the direction orthogonal to the direction along the boundary between the first region and the second region of the bottom surface of the filling portion, that is, in the y-axis direction, is film formation. When the film is peeled off from the film-forming container, the length is not particularly limited as long as the grip portion of the separation portion is held and the separation portion can be easily removed from the main body portion. The length of the grip portion in the y-axis direction is such that the end portion of the grip portion 33 projects outward from the end portion of the main body portion wall portion 22 of the main body portion 2, as shown in FIG. 5 (e), for example. It may have a length, and as shown in FIG. 6A, the end portion of the grip portion 33 may have a length that coincides with the end portion of the main body portion wall portion 22 of the main body portion 2. As shown in FIG. 6B, the length of the grip portion 33 may be such that the end portion of the grip portion 33 is located inside the end portion of the main body portion wall portion 22 of the main body portion 2. When the end portion of the grip portion protrudes outward from the end portion of the main body portion wall portion of the main body portion, the grip portion can be easily gripped. Further, when the end portion of the grip portion coincides with the end portion of the main body portion wall portion of the main body portion, or is located inside the end portion of the main body portion wall portion of the main body portion, it is liquid or liquid. Space can be saved when a plurality of film-forming containers are arranged side by side when drying a gel-like material film.

The area of the grip portion in a plan view is such that when the film-formed film is peeled from the film-forming container, the grip portion of the separation portion can be held and the separation portion can be easily removed from the main body portion. If so, it is not particularly limited. Above all, it is preferable that the area of the grip portion in a plan view is relatively large. The larger the plane view area of the grip portion, the easier it is to hold the grip portion and to apply force.

Further, the grip portion 33 is, for example, as shown in FIGS. 5 (a) to 5 (e) and FIGS. 6 (a) to 6 (b), in the in-plane direction of the separation portion base 31, that is, in the x-axis direction and the y-axis direction. It may be an extending portion, or as shown in FIGS. 7A to 7C, it may be a portion extending in the thickness direction of the separation portion base portion 31, that is, in the z-axis direction.
7 (a) is a schematic plan view showing another example of the separation portion in this embodiment, FIG. 7 (b) is a sectional view taken along line AA of FIG. 7 (a), and FIG. 7 (c) is. It is sectional drawing when the separation part shown in FIGS. 7A and 7B is fitted in the concave part of the main body part.

Regarding the thickness of the grip portion, that is, the length in the z-axis direction, when the film-formed film is peeled from the film-forming container, the grip portion of the separation portion is held and the separation portion is easily removed from the main body portion. The thickness is not particularly limited as long as it can be formed, and is appropriately selected depending on the shape of the grip portion.

For example, when the grip portion extends in the in-plane direction of the separation portion base, that is, in the x-axis direction and the y-axis direction, the thickness of the grip portion is, for example, FIGS. 5 (e) and 6 (a). , (B), when the separating portion 3 is fitted into the recess 23 of the main body portion 2, the portion where the main body portion wall portion 22 of the main body portion 2 and the grip portion 33 of the separating portion 3 overlap in a plan view. It is preferable that the height h2 of the main body portion 2 is the same as the height h1 of the portion where the main body portion wall portion 22 of the main body portion 2 and the grip portion 33 of the separation portion 3 do not overlap in a plan view. For example, as shown in FIGS. 2 (a) to 2 (c) and FIGS. 3 (a) to 3 (b), when the filling portion is filled with the liquid or gel-like material, the liquid or gel-like material is filled in the filling portion. When a liquid or gel-like material is spread using a deploying means after feeding, the height of the portion where the main body wall portion of the main body portion and the grip portion of the separation portion overlap in a plan view is the height of the main body portion. Since the wall portion of the main body portion and the grip portion of the separation portion have the same height as the portion that does not overlap in a plan view, the distance between the bottom surface of the filling portion and the deploying means can be kept constant. Therefore, the liquid or gel-like material can be easily filled in the filling portion, and the work efficiency can be improved. In addition, a liquid or gel-like material film having a uniform thickness can be obtained. As a result, a film having a uniform thickness and good smoothness can be obtained.

The height of the portion where the main body wall portion of the main body and the grip portion of the separation portion overlap in a plan view is the height of the portion where the main body portion wall portion of the main body portion and the grip portion of the separation portion do not overlap in a plan view. Even if it is different from the above, it is possible to keep the distance between the bottom surface of the filling portion and the developing means constant by, for example, arranging the spacer between the film-forming container and the developing means. Therefore, a film having a uniform thickness and good smoothness can be obtained.

In order to make the thickness of the grip portion the above-mentioned thickness, as will be described later, in the main body portion, the main body portion wall portion may have a notch portion in which the grip portion of the separation portion is detachably fitted.

Further, for example, when the grip portion extends in the thickness direction of the base portion of the separation portion, that is, in the z-axis direction, the larger the length of the grip portion in the z-axis direction, the easier it is to hold the grip portion and apply force. It will be easier.

The number of gripping portions is not particularly limited, and may be, for example, one or two or more.

Further, the separating portion preferably has a separating portion wall portion which is a side surface of the filling portion. The liquid or gel-like material can be uniformly filled in the filling portion, and a liquid or gel-like material film having a uniform thickness can be formed. This makes it possible to obtain a film having a uniform thickness and good smoothness.

Since the separation portion wall portion constitutes the side surface of the filling portion, the height of the separation portion wall portion is appropriately set according to the thickness of the target membrane, the thickness of the separation portion base portion, and the like.

Above all, the height h4 of the separating portion wall portion 32 is set in the main body portion 2 when the separating portion 3 is fitted into the recess 23 of the main body portion 2, for example, as shown in FIGS. 4A to 4C. The height h2 of the portion where the main body portion wall portion 22 and the separation portion wall portion 32 of the separation portion 3 overlap in a plan view is flat, and the main body portion wall portion 22 of the main body portion 2 and the separation portion wall portion 32 of the separation portion 3 are flat. It is preferable that the height is the same as the height h1 of the portions that do not overlap visually. For example, as shown in FIGS. 2 (a) to 2 (c) and FIGS. 3 (a) to 3 (b), when the filling portion is filled with the liquid or gel-like material, the liquid or gel-like material is filled in the filling portion. When a liquid or gel-like material is spread using a developing means after feeding, the height of the portion where the main body wall portion of the main body portion and the separation portion wall portion of the separation portion overlap in a plan view is the main body. Since the wall portion of the main body portion of the portion and the wall portion of the separation portion of the separation portion have the same height as the portion that does not overlap in a plan view, the distance between the bottom surface of the filling portion and the deploying means can be kept constant. .. Therefore, the liquid or gel-like material can be easily filled in the filling portion, and the work efficiency can be improved. In addition, a liquid or gel-like material film having a uniform thickness can be obtained. As a result, a film having a uniform thickness and good smoothness can be obtained.

The height of the portion where the main body wall portion of the main body portion and the separation portion wall portion of the separation portion overlap in a plan view is the weight of the main body portion wall portion of the main body portion and the separation portion wall portion of the separation portion in a plan view. Even if the height is different from the height of the unfilled portion, it is possible to keep the distance between the bottom surface of the filling portion and the deploying means constant by, for example, arranging the spacer between the film-forming container and the deploying means. Is. Therefore, a film having a uniform thickness and good smoothness can be obtained.

Further, the height h4 of the separation portion wall portion 32 may be the same as the height h3 of the main body portion wall portion 22 of the main body portion 2, as shown in FIGS. 4A and 4B, for example. As shown in 4 (c), the height h3 of the main body wall portion 22 of the main body 2 may be smaller than the height h3.

The height of the separation portion wall portion means, for example, the height h4 of the separation portion wall portion 32 from the separation portion base portion 31 as shown in FIGS. 4A to 4C.

As for the position of the separating portion wall portion, since the separating portion wall portion constitutes the side surface of the filling portion, the longitudinal direction of the separating portion base portion, that is, the direction along the boundary portion between the first region and the second region of the bottom surface of the filling portion. That is, it is preferable that the separation portion wall portion extends in the x-axis direction.

Further, it is preferable to provide a play between the base portion of the separation portion and the concave portion of the main body portion for detachable fitting. This is because the separation portion can be easily attached to and detached from the recess of the main body portion. In this case, for example, as shown in FIG. 4A, the width w13 of the gap between the boundary portion 13 of the first region 11 and the second region 12 when the separation portion 3 is fitted into the recess 23 of the main body portion 2 is It is preferably relatively small. If the gap between the boundary between the first region and the second region is large, the liquid or gel-like material film gets caught in the gap, and when the film is peeled off from the film-forming container, the film cracks, breaks, etc. May occur.
The width of the gap at the boundary between the first region and the second region can be, for example, less than 0.1 mm.

Further, the separating portion may be fixed to the recess of the main body portion by the fixing portion. The fixing portion is a portion for fixing the separating portion to the recess of the main body portion. In the case of forming a liquid or gel-like material using the film-forming container of this embodiment, when the liquid or gel-like material film is formed and then the liquid or gel-like material film is dried. The volume of the liquid or gel-like material film shrinks during the drying process. Since the separating portion is fixed to the recess of the main body by the fixing portion, it is possible to prevent the separating portion from floating from the recess of the main body due to the volume shrinkage of the liquid or gel-like material film during drying. can do. For example, as described above, when a play is provided for the detachable fitting between the base of the separation portion and the recess of the main body, the separation portion floats when the liquid or gel-like material film is dried. It can be effectively suppressed from being stored.

The fixing portion may be any as long as the separating portion can be fixed to the recess of the main body portion. For example, the separating portion may have a fixing portion, or the fixing portion may be arranged separately from the separating portion. Good. When the separating portion has a fixed portion, examples of the fixing portion include a convex portion, a snap-fit portion, an insertion portion, and the like. When the fixing portion is arranged separately from the separating portion, the fixing portion may include, for example, an adhesive tape, a clip, a screw, or the like. Further, as the fixing portion, one kind of fixing portion may be used, or two or more kinds of fixing portions may be used. For example, the separating portion may have both a convex portion and a snap-fit portion, or both a snap-fit portion and an insertion portion, as a fixing portion.

When the fixing portion is a convex portion, the separating portion can be fixed to the concave portion of the main body portion by the convex portion. As a result, it is possible to prevent the separation portion from floating from the recess of the main body portion when the membrane is dried.

The position of the convex portion is not particularly limited as long as it does not interfere with the formation of the liquid or gel-like material film. For example, the convex portion is located at the separation portion base, the separation portion wall portion, and the grip portion. Can be done. For example, in the examples shown in FIGS. 8A to 8D, the convex portion 36 is arranged on the side surface of the separating portion wall portion 32 on the side in contact with the main body portion wall portion 22. Further, in the example shown in FIG. 9A, the convex portion 36 is arranged on the side surface of the grip portion 33 on the side in contact with the main body portion wall portion, and in the example shown in FIG. 9B, the convex portion 36 is , Is arranged on the side surface of the separation portion base 31 on the side in contact with the main body portion wall portion.
8 (a) is a schematic plan view showing an example of the separation portion in this embodiment, FIG. 8 (b) is a sectional view taken along line AA of FIG. 8 (a), and FIG. 8 (c) is FIG. BB line cross-sectional view of (a), FIG. 8 (d) is a cross-sectional view when the separation portion shown in FIG. 8 (a) is fitted into the recess of the main body portion.

The size of the convex portion is not particularly limited as long as the separated portion can be fixed to the concave portion of the main body portion and the separated portion can be attached to and detached from the main body portion. For example, when the separated portion is manufactured by injection molding, the size of the convex portion may be a size that can be injection molded.

Above all, the width of the convex portion is preferably relatively small. This is because the smaller the width of the convex portion, the easier it is to attach / detach the separated portion from the main body portion. On the other hand, if the width of the convex portion is too large, it may be difficult to attach / detach the separating portion to the concave portion of the main body portion. Specifically, the width of the convex portion can be several hundred μm or more and several mm or less.

The height of the convex portion is, for example, equal to or greater than the width of the gap between the first region and the second region, and the width of the gap between the first region and the second region + 0.1 mm or less. Can be. When the height of the convex portion is within the above range, the separation portion can be easily attached to and detached from the main body portion, and it is possible to further prevent the separation portion from floating from the concave portion of the main body portion when the film is dried.

The shape of the convex portion is not particularly limited, and examples thereof include a prismatic shape such as a square columnar shape and a triangular columnar shape, a columnar shape, and a hemispherical shape.

The number of convex portions is not particularly limited, and may be, for example, one or two or more. When there is one convex portion, for example, in FIGS. 8 (a) and 9 (a) to 9 (b), there is a form in which only one of the two convex portions 36 is provided.

Further, when the fixing portion is a snap-fit portion, the separating portion can be fixed to the recess of the main body portion by the snap-fit portion. As a result, it is possible to prevent the separation portion from floating from the recess of the main body portion when the membrane is dried.

The snap-fit portion can have a claw portion and a locking portion. Usually, for example, as shown in FIGS. 10A to 10B, the separating portion 3 has a locking portion 39, and the main body portion 2 has a claw portion 38. In the snap-fit portion 37, the separation portion 3 can be fixed to the main body portion 2 by inserting the claw portion 38 into the hole 40 of the separation portion 3 and locking the claw portion 38 to the locking portion 39. it can.
10 (a) is a schematic plan view showing an example of the separation portion in this embodiment, FIG. 10 (b) is a sectional view taken along line AA of FIG. 10 (a), and FIG. 10 (a) shows. It is sectional drawing when the separated part shown is fitted in the concave part of the main body part.

The structure of the snap-fit portion is not particularly limited as long as the separation portion can be attached to and detached from the main body portion, and a general snap-fit structure can be applied.

The positions of the claws and the locking portions of the snap-fit portion are not particularly limited as long as they do not interfere with the formation of the liquid or gel-like material film. For example, the locking portion is the grip portion of the separating portion. It can be located, and the claw portion can be located in the notch portion of the main body portion wall portion of the main body portion. For example, in the examples shown in FIGS. 10A to 10B, the locking portion 39 is arranged in the grip portion 33 of the separating portion 3, and the claw portion 38 is a notch portion of the main body portion wall portion of the main body portion 2. It is arranged at 24.

The number of snap-fit portions is not particularly limited, and may be, for example, one or two or more.

Further, in the snap-fit portion, a protective portion may be arranged in order to prevent the claw portion from breaking.

Further, when the fixing portion is an insertion portion, the separation portion can be fixed to the recess of the main body portion by the insertion portion. As a result, it is possible to prevent the separation portion from floating from the recess of the main body portion when the membrane is dried.

The insertion portion may have an insertion claw portion and an insertion hole into which the insertion claw portion can be inserted. Usually, for example, as shown in FIG. 11, the separating portion 3 has an insertion claw portion 71, and the main body portion 2 has an insertion hole 72. More specifically, the insertion claw portion 71 is arranged on the side surface of the separation portion base portion 31 of the separation portion 3 on the side of the main body portion 2 on the side in contact with the first region 11 of the main body portion bottom portion 21. Further, the insertion hole 72 is arranged at the end of the recess 23 of the main body 2 on the first region 11 side.
In the insertion portion, the separation portion 3 can be fixed to the main body portion 22 by inserting the insertion hole 72 of the main body portion 2 into the insertion claw portion 71 of the separation portion 3. For example, when the separation part is manufactured by injection molding, the injection molded product may be distorted, but even if the separation part is slightly distorted by inserting the insertion claw part of the separation part into the insertion hole of the main body part. , Distortion can be corrected when the separation part is fitted into the main body part.
Note that FIG. 11 is an exploded plan view showing an example of the film-forming container of this embodiment.

The size of the insertion claw is particularly large as long as the separation part can be fixed to the recess of the main body by inserting it into the insertion hole and the separation part can be attached to and detached from the main body. Not limited. For example, when the separated portion is manufactured by injection molding, the size of the insertion claw portion may be a size that allows injection molding.
Specifically, the width and length of the insertion claw portion can be several hundred μm or more and several mm or less.

In addition, the size of the insertion hole is such that the separation part can be fixed to the recess of the main body part by inserting the insertion claw part into the insertion hole, and the separation part can be attached to and detached from the main body part. If so, there is no particular limitation. For example, when the main body is manufactured by injection molding, the size of the insertion hole may be a size that can be injection molded.
Specifically, the width and length of the insertion hole can be several hundred μm or more and several mm or less.

The shape of the insertion claw and the insertion hole is such that the separation part can be fixed to the recess of the main body by inserting the insertion claw into the insertion hole, and the separation part can be attached to and detached from the main body. If there is, there is no particular limitation. Specific shapes include rectangles, trapezoids, semicircles, semi-ellipses, triangles and the like.

The number of insertion claws and insertion holes is not particularly limited, and may be, for example, one or two or more, respectively. For example, when the separated portion is an injection-molded product and the ends of the separated portions are warped, it is preferable to arrange the insertion claws at the ends of the separated portions. Further, for example, when the separating portion is an injection molded product and the central portion of the separating portion is warped, it is preferable to arrange the insertion claw portion in the central portion of the separating portion.

Further, it is preferable that the separation portion base portion and the separation portion wall portion have hydrophilicity. When the separation portion base portion and the separation portion wall portion are hydrophilic, the filling portion can be filled with a liquid or gel-like material to satisfactorily form a liquid or gel-like material film.

Regarding the hydrophilicity of the separation part base and the separation part wall, for example, the contact angle of the surface of the separation part base and the separation part wall with water is preferably in the range of 30 ° or more and 95 ° or less. , 30 ° or more and 85 ° or less, particularly preferably 30 ° or more and 60 ° or less.
When the contact angle is within the above range, a liquid or gel-like material film can be uniformly formed in the filled portion. Further, when the liquid or gel-like material film is dried, the adhesion between the base portion of the separation portion and the wall portion of the separation portion and the liquid or gel-like material film can be improved, and the material film floats on the film during drying. , Wrinkles, cracks, etc. can be suppressed. Further, when the film is peeled from the film-forming container, the film can be easily peeled from the separated portion, and cracks, breaks, wrinkles and the like can be suppressed from occurring in the film. On the other hand, if the contact angle is too small, the adhesion between the base of the separation part and the wall of the separation part and the liquid or gel-like material film becomes too strong, and the film cannot be peeled off when the film is peeled off after drying. Or, the film may crack. Further, if the contact angle is too high, the adhesion between the base portion of the separation portion and the wall portion of the separation portion and the liquid or gel-like material film is weak, and the film may be deformed such as floating or wrinkles during drying.

As will be described later, when the bottom of the main body and the wall of the main body have hydrophilicity, the hydrophilicity of the base of the separation part and the wall of the separation part is the same as the hydrophilicity of the bottom of the main body and the wall of the main body. Well, it may be different.

When the hydrophilicity of the separation part base and the separation part wall part is different from the hydrophilicity of the main body part bottom and the main body part wall part, the hydrophilicity of the separation part base and the separation part wall part is different from the hydrophilicity of the main body part bottom part and the main body part wall. It is preferably higher than the hydrophilicity of the portion. That is, it is preferable that the contact angles of the surfaces of the separation portion base and the separation portion wall with water are smaller than the contact angles of the surfaces of the main body bottom and the main body wall with water. By removing the separation part from the main body, when the membrane is peeled off from the main body, the hydrophilicity of the separation part base and the separation part wall part is higher than the hydrophilicity of the main body part bottom and the main body part wall part. It is possible to prevent the membrane from peeling off from the separation portion. Thereby, work efficiency can be improved.

When the contact angle of the surface of the separation part base and the separation part wall part with water is smaller than the contact angle of the surface of the main body part bottom and the main body part wall part with water, the contact angle of the surface of the separation part base and the separation part wall part with respect to water The contact angle may be smaller than the above range. For example, the contact angle of the surfaces of the separation portion base portion and the separation portion wall portion with water may be less than 30 °, and in this case, it is preferably in the range of 10 ° or more and less than 30 °. When the contact angle is within the above range, when the liquid or gel-like material film is dried, the adhesion between the separation part base and the separation part wall and the liquid or gel-like material film can be improved. It can be done, and peeling and the like can be suppressed.

Here, for the contact angle with water, a contact angle measuring device Drop Master-700 manufactured by Kyowa Interface Science Co., Ltd. was used, and a droplet of 1.5 mL of pure water was prepared using a 22 G stainless needle to prepare a measurement surface. It can be obtained by measuring the contact angle with water 1000 milliseconds after the droplet is brought into contact with the water.

Further, the separation portion base portion and the separation portion wall portion may be surface-treated in order to adjust the contact angle of the surface with water. That is, the separation portion base portion and the separation portion wall portion may have a hydrophilic treated surface on the surface. The surface treatment is not particularly limited as long as it can increase the hydrophilicity of the surface of the plastic, and for example, corona discharge treatment, plasma treatment, UV ozone treatment, excimer UV treatment, electron beam irradiation treatment, etc. Laser processing and the like can be mentioned.

Further, when the membrane is heated before the membrane is peeled from the membrane-forming container, the separated portion preferably has heat resistance. As for the heat resistance of the separating portion, it is preferable that the separating portion has heat resistance with respect to the heating temperature. Above all, the deflection temperature under load of the material of the separation part is preferably higher than the heating temperature, for example, it can be 100 ° C. or higher, preferably 130 ° C. or higher, and more preferably 150 ° C. or higher. The upper limit of the deflection temperature under load is not particularly limited.

The deflection temperature under load can be measured by a method based on JIS K7191.

As the material of the separation part, a liquid or gel-like material can be filled in the filling part composed of the main body part and the separation part to form a film, and after the film formation, the film is formed from the separation part. The material is not particularly limited as long as it can be peeled off, and can be appropriately selected depending on the type of liquid or gel-like material, the use of the film, and the like.

Examples of the material of the separation portion include plastic. As the plastic, general ones can be used, and specifically, acrylic resin, ABS resin (acrylonitrile-butadiene-styrene copolymer resin), acrylonitrile styrene, polyethylene terephthalate, polybutylene terephthalate, polypropylene, etc. Examples thereof include polyethylene, polyacetal, polystyrene, polyvinyl chloride, polyamide, polycarbonate, polyarylate, polysulfone, polyether ether ketone, cyclic polyolefin and the like. Of these, acrylic resins and polyvinyl chlorides are preferable, and acrylic resins are particularly preferable, from the viewpoint of hydrophilicity. Further, from the viewpoint of heat resistance, polypropylene and polycarbonate are preferable. Further, for example, when forming a biocompatible film, a medical plastic is preferably used. As the medical plastic, a commercially available medical grade plastic can be used.

The material of the separation part may be the same as or different from the material of the main body part. When the material of the separating portion is the same as that of the main body portion, the separating portion and the main body portion can be molded at the same time. Further, when the material of the separating portion is different from the material of the main body portion, for example, the hydrophilicity of the separating portion and the main body portion can be made different.

(2) Main body portion The main body portion in this embodiment is a member including the first region on the bottom surface of the filling portion. Further, the main body portion in the present embodiment has a main body portion bottom portion including the first region of the bottom surface of the filling portion and a main body portion wall portion serving as a side surface of the filling portion, and the main body portion bottom portion is other than the first region. Has a recess in the area. A separating portion is detachably fitted in the recess on the bottom of the main body.

The plan view shape of the bottom portion of the main body can usually be the same as the plan view shape of the filling portion, and is appropriately selected according to the plan view shape of the filling portion. Examples of the plan view shape of the bottom portion of the main body include a rectangular shape and a trapezoidal shape.

Further, the bottom portion of the main body portion includes a first region on the bottom surface of the filling portion, and has a recess in a region other than the first region. That is, the bottom portion of the main body portion can have a portion including the first region on the bottom surface of the filling portion and a recess in a region other than the first region.

The plan view shape of the recess at the bottom of the main body may be any shape as long as the separation portion can be detachably fitted into the recess, and can usually be the same as the plan view shape of the separation portion base. It is appropriately selected according to the plan view shape of the base. As the plan view shape of the concave portion, for example, a rectangular shape can be mentioned.

The cross-sectional shape of the recess may be any shape as long as the separating portion can be detachably fitted into the recess, and is appropriately selected according to the cross-sectional shape of the base of the separating portion. For example, in the longitudinal direction of the bottom portion 31 of the main body, that is, the cross section in the y-axis direction, the cross-sectional shape of the recess 23 may be rectangular as shown in FIG. 4 (a), and is shown in FIG. 4 (b). As described above, it may have an inverted trapezoidal shape.

As for the depth of the recess 23, when the separating portion is fitted into the recess, for example, as shown in FIG. 4A, the depth of the first region 11 and the depth of the second region 12 of the bottom surface 10a of the filling portion 10 The first region 11 and the second region 12 are flush with each other, that is, the depth of the first region 11 of the filling portion 10 is the second region as shown in FIG. 4C. It is preferably set so as to be larger than the depth of 12. That is, as shown in FIG. 4A, the depth of the recess 23 with respect to the portion of the first region 11 of the bottom portion 21 of the main body portion is the same as the thickness of the separation portion base 31 of the separation portion 3, or FIG. As shown in (c), it is preferably smaller than the thickness of the separation portion base 31 of the separation portion 3. In these cases, it is possible to prevent the film from cracking, breaking, wrinkling, etc. when the separated portion is removed from the main body when the film-formed film is peeled from the film-forming container.

The area of the recess in a plan view is not particularly limited as long as the separated portion can be easily removed from the main body when the film-formed film is peeled from the film-forming container. Above all, it is preferable that the area of the concave portion at the bottom of the main body in a plan view is smaller than the area of the first region of the bottom of the main body in a plan view. That is, it is preferable that the second region on the bottom surface of the filling portion is smaller than the first region on the bottom surface of the filling portion. Since the film portion formed on the separation portion may not be used as a product from the viewpoint of cleanliness, for example, the area of the concave portion at the bottom of the main body in a plan view is the first region of the bottom of the main body. By being smaller than the plan area of the portion, waste of liquid or gel-like material can be reduced.
For example, the area of the recess in the bottom of the main body in a plan view varies depending on the size of the filling portion, but it may be 1/2 or less with respect to the area in the plan view of the first region of the bottom of the main body. It is possible, and above all, it is preferably 1/8 or less, and more preferably 1/10 or less.

Further, as for the height of the main body wall portion, since the main body wall portion constitutes the side surface of the filling portion, the height of the main body portion wall portion with respect to the bottom portion of the main body portion is usually the same as the depth of the filling portion. It can be set appropriately according to the depth of the filling portion.

The width of the wall portion of the main body is not particularly limited, and is appropriately set according to the size of the film-forming container of this embodiment. Further, the width of the main body wall portion may be constant or may be partially different.

When the widths of the main body wall portions are partially different, for example, as shown in FIGS. 12 (a) and 12 (b), the second portion of the main body portion wall portion 22 in the lateral direction of the recess 23, that is, the bottom surface of the filling portion. The widths w1 and w2 of the main body wall portion 22 extending in the direction orthogonal to the direction along the boundary portion 13 of the first region 11 and the second region 12, that is, in the y-axis direction, are such that one width w1 is the other width. It may be larger than w2. For example, as shown in FIGS. 2 (a) to 2 (c) and FIGS. 3 (a) to 3 (b), when the filling portion is filled with the liquid or gel-like material, the liquid or gel-like material is filled in the filling portion. When the liquid or gel-like material is spread using the developing means after the supply, one width w1 is larger than the other width w2 as described above, so that the liquid or gel-like material is spread by using the developing means. Before spreading the material of, the deploying means can be placed on the portion of the main body portion wall portion 22 having the larger width w1, and the deploying means can be stably held. Therefore, the liquid or gel-like material can be stably spread on the filled portion. Further, when the liquid or gel-like material is spread by using the developing means, from the portion of the main body portion wall portion 22 having the larger width w1 toward the portion of the main body portion wall portion 22 having the smaller width w2, When the deploying means is moved, the excess liquid or gel-like material is scraped off from the portion of the main body portion wall portion 22 having the smaller width w2. At this time, since the other width w2 is smaller than the one width w1 as described above, the excess liquid or gel-like material can be easily scraped off from the main body wall portion 22 having the smaller width w2. be able to.

Further, for example, as shown in FIGS. 12A and 12B, it is orthogonal to the lateral direction of the recess 23, that is, the direction along the boundary portion 13 of the first region 11 and the second region 12 on the bottom surface of the filling portion. Of the widths w1 and w2 of the portion of the main body wall portion 22 extending in the direction to be formed, that is, in the y-axis direction, when one width w1 is larger than the other width w2, the larger width w1 is the length of the recess 23. It may be larger than the widths w3 and w4 of the portion of the main body portion wall portion 22 extending in the direction, that is, along the boundary portion 13 of the first region 11 and the second region 12 on the bottom surface of the filling portion, that is, in the x-axis direction. As described above, the larger width w1 may be larger than the widths w3 and w4 in order to place the deploying means. Further, since the widths w2, w3, and w4 are smaller than the width w1, the material used for the film-forming container can be reduced.

On the other hand, when the width of the wall portion of the main body is constant, for example, when a film-forming container is manufactured by injection molding, molding is easy.

As for the position of the main body wall portion, since the main body wall portion constitutes the side surface of the filling portion, the main body portion wall portion can be extended so as to surround the filling portion.

Further, the main body wall portion 22 may have a notch portion 24 into which the grip portion 33 of the separation portion 3 is detachably fitted, as shown in FIGS. 1 (a) and 1 (b), for example. When the wall portion of the main body has a notch, it becomes easier to grip the grip portion of the separation portion, and when the film is peeled from the membrane-forming container, the grip portion of the separation portion is held and the separation portion is held by the main body portion. Can be easily removed from.

The position of the notch is not particularly limited as long as the grip of the separation portion can be detachably fitted to the notch, and the notch is usually the wall of the main body. It can be located in a portion adjacent to the recess of, and is appropriately selected according to the position of the grip portion of the separation portion.
For example, when the portion adjacent to the long side of the recess of the main body wall has a notch, as shown in FIGS. 1 (a), 1 (b) and 12 (b), the recess of the main body 22 The notch 24 may be located in a part of the portion adjacent to the long side of the 23, and as shown in FIG. 12A, the portion adjacent to the long side of the recess 23 of the main body wall portion 22. Notches 24 may be located in all of the above.

The depth of the cutout portion 24 may be smaller than the height of the main body portion wall portion 22 from the bottom surface of the recess 23, as shown in FIGS. 1 (a), 1 (b) and 12 (a), for example. , As shown in FIG. 12B, it may be the same as the height of the main body wall portion 22 from the bottom surface of the recess 23, and although not shown, it is larger than the height of the main body portion wall portion from the bottom surface of the recess. You may. That is, for example, as shown in FIGS. 1 (a), 1 (b) and 12 (a), the recess 23 may be recessed from the notch 24, and as shown in FIG. 12 (b), the recess 23 may be recessed. The portion 24 and the recess 23 may be flush with each other, and although not shown, the notch may be recessed from the recess.

The shape of the notch in a plan view is such that when the film-formed film is peeled from the film-forming container, the separation portion can be easily removed from the main body by holding the grip portion of the separation portion. The shape is not particularly limited, and can usually be the same as the plan view shape of the grip portion. Examples of the plan view shape of the notch portion include a rectangular shape and the like.

The number of cutouts can be the same as the number of grips of the separation portion, and may be, for example, one or two or more.

Further, it is preferable that the bottom portion of the main body portion and the wall portion of the main body portion have hydrophilicity. When the bottom portion of the main body and the wall portion of the main body are hydrophilic, the filling portion can be filled with a liquid or gel-like material to satisfactorily form a liquid or gel-like material film.

The hydrophilicity of the bottom portion of the main body and the wall portion of the main body can be the same as the hydrophilicity of the base portion of the separation portion and the wall portion of the separation portion.

Further, the bottom of the main body and the wall of the main body may be surface-treated in order to adjust the contact angle of the surface with water. That is, the bottom of the main body and the wall of the main body may have a hydrophilic treated surface on the surface. Since the surface treatment is the same as that described above, the description thereof will be omitted here.

Further, when the film is heated before the film is peeled off from the film-forming container, the main body preferably has heat resistance. The heat resistance of the main body portion can be the same as the heat resistance of the separation portion described above.

As the material of the main body, a liquid or gel-like material can be filled in the filling portion composed of the main body and the separating portion to form a film, and after the film formation, the film is formed from the main body. The material is not particularly limited as long as it can be peeled off, and can be appropriately selected depending on the type of liquid or gel-like material, the use of the film, and the like.

The material of the main body can be the same as the material of the separation part described above.

(3) Filling part The filling part in this embodiment is a part for filling a liquid or gel-like material, and has a bottom surface and a side surface. Further, the bottom surface of the filling portion has a first region and a second region located at the end of the bottom surface and adjacent to the first region, and these first region and the second region are separable. ing. The first region and the second region can be separated by having the main body portion including the first region and the separating portion including the second region in the film-forming container of this embodiment.

The first region is preferably larger than the second region. Since the film portion formed on the separation portion may not be used as a product from the viewpoint of cleanliness, for example, the first region composed of the main body portion is the second region composed of the separation portion. By being larger than, waste of liquid or gel-like material can be reduced.
For example, the area of the second region can be 1/2 or less, more preferably 1/8 or less, and more preferably 1/10 or less of the area of the first region.

Further, the filling portion 10 preferably has a groove 41 on the bottom surface 10a, for example, as shown in FIGS. 13 (a) to 13 (c) and FIGS. 14 (a) to 14 (c). That is, it is preferable that the portion of the first region 11 of the bottom portion 21 of the main body portion 2 and the separation portion base portion 31 of the separation portion 3 have a groove. The groove 41 is usually located around a region (hereinafter, referred to as an effective film-forming region) 42 which is an effective region of the film formed in the filling portion 10.
13 (a) is a schematic plan view showing another example of the film-forming container of this embodiment, and FIG. 13 (b) is a sectional view taken along line AA of FIG. 13 (a) and FIG. 13 (c). ) Is a cross-sectional view taken along the line BB of FIG. 13 (a). 14 (a) is a schematic plan view showing another example of the film-forming container of this embodiment, and FIG. 14 (b) is a sectional view taken along line AA of FIG. 14 (a) and FIG. 14 (c). ) Is a cross-sectional view taken along the line BB of FIG. 14 (a).

15 (a) to 15 (b) are process diagrams showing an example of a film forming method using the film forming container of this embodiment. As shown in FIG. 15 (a), the filling portion 10 is filled with a liquid or gel-like material to form a liquid or gel-like material film 51b, and then as shown in FIG. 15 (b), the liquid is liquid. Alternatively, the gel-like material film is dried to remove the solvent, and the film 51 is obtained.
The volume of the liquid or gel-like material film 51b shrinks during the drying process. At this time, since the filling portion 10 has a groove 41 located around the effective film forming region 42 on the bottom surface 10a, the liquid or material enters the groove 41, and the liquid or gel-like material film 51b is caught in the groove 41. As a result, it is possible to prevent the film 51 from being deformed or cracked such as floating or wrinkles during drying. Therefore, the yield can be improved.

As for the position of the groove, the groove may be located around the effective film forming region. Above all, when the plan view shape of the effective film-forming region is rectangular, it is preferable that the grooves are located at least on two opposite sides of the four sides of the effective film-forming region. Further, when the plan view shape of the effective film forming region is a rectangular shape other than a square, for example, as shown in FIGS. 13 (a) to 13 (c), the groove 41 is the length of the four sides of the effective film forming region 42. It is preferably located on at least two sides of the side. This is because it is considered that the length of the groove can be increased by locating the groove on the long side, and the effect of suppressing the floating of the film during drying is enhanced. In particular, as shown in FIGS. 14A to 14C, for example, the grooves 41 are preferably located on the four sides of the effective film forming region 42.

Further, the groove may be located around the effective film forming region. For example, as shown in FIGS. 13 (a) to 13 (c) and FIGS. 14 (a) to 14 (c), the groove 41 is a filling portion. It may be located along the end of the bottom surface 10a of the filling portion 10, and as shown in FIGS. 16A to 16B, the groove 41 is located inside the end of the bottom surface 10a of the filling portion 10. May be.
16 (a) is a schematic plan view showing another example of the film-forming container of this embodiment, and FIG. 16 (b) is a sectional view taken along line AA of FIG. 16 (a).

Further, the number of effective film forming regions may be one or two or more. For example, as shown in FIGS. 17A to 17C, when the bottom surface 10a of the filling portion 10 has a plurality of effective film forming regions 42, the groove 41 may be located around each effective film forming region 42. it can. When the number of effective film-forming regions is large, the area of the film-forming container becomes large, so that the film may crack at the center of the bottom surface of the filling portion during drying. On the other hand, since the grooves are located around each effective film-forming region, cracking of the film during drying can be suppressed.
17 (a) is a schematic plan view showing another example of the film-forming container of this embodiment, and FIG. 17 (b) is a sectional view taken along line AA of FIG. 17 (a) and FIG. 17 (b). c) is a cross-sectional view taken along the line BB of FIG. 17 (a).

Further, the groove may be located around the effective film forming region. For example, when the effective film forming region has a rectangular shape in a plan view, the groove 41 is effectively formed as shown in FIG. 14A. It may be located at the corner of the film region 42, and the groove 41 may not be located at the corner of the effective film forming region 42 as shown in FIGS. 18A and 18B.

Above all, when the film is peeled from the film-forming container, if the film is not cut in advance along the effective film-forming area, that is, along the groove, the groove is formed at the corner of the effective film-forming area. It is preferably not located. When the groove is located at the corner of the effective membrane-forming region, the liquid or gel-like material film enters and gets caught in the groove at the corner of the effective membrane-forming region, so that the adhesion between the membrane and the bottom surface of the filling portion is improved. It becomes too strong and it becomes difficult to peel the film from the film-forming container, and when the film is peeled from the film-forming container, the film may be cracked or broken.

When the groove is not located at the corner of the effective film-forming region, the length of the groove is appropriately selected according to the type and viscosity of the liquid or gel-like material, the thickness of the target film, and the like. For example, when the effective film-forming region has a rectangular shape, the ratio of the groove lengths on one side of the effective film-forming region is 75% or more with respect to 100% of the length of one side of the effective film-forming region. It is preferably 93% or more, and more preferably 93% or more. If the ratio of the length of the groove is too small, the film may float and deform easily at the corner of the effective film forming region without the groove, and the yield may decrease.

Further, the groove may be located around the effective film forming region. For example, as shown in FIG. 14 (a), the groove 41 may be continuous, and FIGS. 19 (a) and 19 (b) show. As shown, the grooves 41 may be discontinuous.
Note that FIG. 19A is a schematic plan view showing another example of the film-forming container of this embodiment, and FIG. 19B is a sectional view taken along line AA of FIG. 19A.

When the grooves are discontinuous, the lengths of the continuous groove portion and the non-continuous groove portion are appropriately selected according to the type and viscosity of the liquid or gel-like material, the thickness of the target film, and the like. To. For example, when the grooves are discontinuous and the effective film-forming region is rectangular, the ratio of the total length of the portions where the grooves are continuous on one side of the effective film-forming region is the effective film-forming region. It is preferably 75% or more, and more preferably 93% or more, with respect to 100% of the length of one side of the region. If the ratio of the total length of the portions where the grooves are continuous is too small, the film tends to peel off at the portions where the grooves are not continuous during drying, and the yield may decrease.

Further, the length of the portion where the grooves are not continuous is preferably 3 cm or less, for example. If the length of the portion where the grooves are not continuous is too long, the film tends to peel off at the portion where the grooves are not continuous, and the yield may decrease.

The depth of the groove is not particularly limited as long as the depth is such that the liquid or gel-like material film can enter and get caught in the groove, and the type and viscosity of the liquid or gel-like material, It is appropriately set according to the thickness of the target film and the like. For example, the depth of the groove can be 0.1 mm or more, and more preferably 0.5 mm or more, and more preferably 1 mm or more. If the groove depth is too small, the effect of the groove may not be sufficiently obtained. The upper limit of the groove depth may be smaller than the thickness of the bottom of the main body of the main body and the thickness of the base of the separation of the separation, and is not particularly limited.

Further, the depth of the groove may be constant or partially different regardless of whether the groove is continuous or discontinuous.

When the depth of the groove is partially different, by adjusting the depth of the groove, it is possible to adjust the degree of the effect of allowing the liquid or gel-like material film to enter the groove and catch it, and it is partially possible. The degree of the above effect can be made different. For example, by making the depth of the groove located at the base of the separating portion of the separating portion larger than the depth of the groove located at the bottom of the main body of the main body, the adhesion between the membrane and the separating portion can be improved. It can be made larger than the adhesion with. Thereby, by removing the separating portion from the main body portion, when the membrane is peeled from the main body portion, the membrane can be prevented from being peeled off from the separating portion.

The width of the groove is not particularly limited as long as the width is such that a liquid or gel-like material film can enter and be caught in the groove, and the type, viscosity, and purpose of the liquid or gel-like material are used. It is appropriately set according to the thickness of the film to be formed, the size of the filled portion, and the like. For example, the width of the groove can be 0.1 mm or more, and more preferably 0.5 mm or more, and more preferably 1 mm or more. Further, the width of the groove can be 2 mm or less, and more preferably 1 mm or less. If the width of the groove is too small, if the viscosity of the liquid or gel-like material is relatively high, it becomes difficult for the material to enter the groove, and the effect of the groove may not be obtained. Further, the larger the groove width, the easier it is for the material to enter the groove even when the viscosity of the liquid or gel-like material is relatively high, but the larger the groove width, the lower the material yield.

Further, it is preferable to provide a play between the concave portion of the main body portion and the bottom portion of the separated portion of the separated portion for detachable fitting. In this case, for example, as shown in FIGS. 20A to 20C, the widths w11 and w12 of the groove 41 are the first region 11 and the second region 11 and the second when the separation portion 3 is fitted into the recess of the main body portion 2. It is preferably larger than the width w13 of the gap of the boundary portion 13 of the region 12. That is, the width w13 of the gap between the boundary portions 13 of the first region 11 and the second region 12 when the separation portion 3 is fitted into the recess of the main body portion 2 is smaller than the widths w11 and w12 of the grooves 41. preferable. If the gap between the boundary between the first region and the second region is large, the liquid or gel-like material film gets caught in the gap, and when the film is peeled off from the film-forming container, the film cracks, breaks, etc. May occur.
20 (a) is a schematic perspective view showing another example of the film-forming container of this embodiment, and FIG. 20 (b) is a sectional view taken along line AA of FIG. 20 (a), FIG. 20 (b). c) is a cross-sectional view taken along the line BB of FIG. 20 (a).

Further, the width of the groove may be constant or partially different regardless of whether the groove is continuous or discontinuous.

Further, for example, as shown in FIG. 21, the angle θ1 of the shoulder portion of the groove 41 is preferably, for example, 90 ° ± 5 °. When the angle of the shoulder portion of the groove is within the above range, the liquid or gel-like material can easily enter the groove, and the effect of allowing the liquid or gel-like material film to enter the groove and catch it can be sufficiently obtained. .. On the other hand, if the angle of the shoulder portion of the groove is small, the liquid or gel-like material is difficult to enter the groove, and the above effect may not be obtained. Further, if the angle of the shoulder portion of the groove is large, the above effect may not be sufficiently obtained.

Further, when the groove is located at the corner of the effective film-forming region, the plan-view shape of the groove at the corner of the effective film-forming region is not particularly limited, and is, for example, a straight line as shown in FIG. 14A. It may have a shape, or as shown in FIGS. 22 (a) to 22 (c), it may have a chamfered shape with chamfered corners.

Examples of the plan view shape of the filling portion include a rectangular shape and a trapezoidal shape.

For example, when the plan view shape of the filling portion is quadrangular, as shown in FIGS. 23 (a) and 23 (b), the length d1 of the boundary portion 13 of the first region 11 and the second region 12 of the bottom surface 10a is It is preferable that the length of the side of the bottom surface 10a opposite to the side of the separation portion 3 is d2 or more. The film is peeled from the film-forming container when the length d1 of the boundary portion between the first region and the second region of the bottom surface is equal to or more than the length d2 of the side opposite to the side on the separation portion side of the bottom surface. At that time, the force is easily transmitted to the film, and it becomes easy to peel off. On the other hand, when the length d1 of the boundary portion between the first region and the second region of the bottom surface is shorter than the length d2 of the side opposite to the side on the separation portion side of the bottom surface, the film is peeled from the film-forming container. At that time, the force applied to the membrane located at the end in the longitudinal direction of the filling portion becomes unstable, and the membrane may be cracked or broken.

Further, for example, when the plan view shape of the filling portion is quadrangular, as shown in FIGS. 23 (a) and 23 (b), the first region 11 and the second region 12 of the main body bottom 21 of the main body 2 It is preferable that the angles θ2 and θ3 on the boundary portion 13 side are 90 ° or less. When the angles θ2 and θ3 of the bottom of the main body of the main body on the boundary portion side of the first region and the second region are 90 ° or less, the film is formed when the film is peeled from the film-forming container. The force is easily transmitted and it is easy to peel off. On the other hand, if the angles θ2 and θ3 of the bottom of the main body of the main body on the boundary portion side of the first region and the second region are larger than 90 °, the film is filled when the film is peeled from the film-forming container. The force applied to the film located at the end in the longitudinal direction of the portion becomes unstable, and the film may be cracked or broken.

(4) Method for manufacturing a film-forming container The method for manufacturing a film-forming container in this embodiment is not particularly limited as long as it can manufacture a main body portion and a separation portion, and is, for example, injection molding or the like. Examples include a molding method and a processing method such as cutting. In the case of injection molding, the main body portion and the separation portion may be molded at the same time using one mold, or may be molded separately. When the main body portion and the separation portion are simultaneously molded using one mold, the mold cost can be reduced. On the other hand, when the main body and the separated portion are molded separately, for example, the main body and the separated portion can be molded using different materials. Further, when the main body portion and the separation portion are molded separately, the molding is easy.

Further, when the main body portion and the separating portion are molded using one mold, the main body portion 2 and the separating portion 3 may be connected in a divisible manner, for example, as shown in FIG. 24. That is, it can be a film-forming container set 1A in which the main body 2 and the separation 3 are connected. This film-forming container set can be used by separating the main body portion and the separating portion at the time of use. In this case, it is possible to prevent the separation portion from being lost before using the film-forming container.

When the main body and the separating portion are connected in a divisible manner, for example, by making the connecting portion of the main body and the separating portion thin, the main body and the separating portion can be easily separated.

(5) Applications The film-forming container of this embodiment can be used for film-forming a liquid or gel-like material.
The film-forming method using the film-forming container of this embodiment will be described later, and thus the description thereof will be omitted here.

2. 2. Second Aspect The membrane-forming container of the present aspect is a film-forming container having a filling portion for filling a liquid or gel-like material, and the filling portion has a bottom surface and a side surface, and the filling portion is provided. The bottom surface of the portion has a first region and a second region located at the end of the bottom surface and adjacent to the first region, and the first region and the second region are separable. The film-forming container has a main body including the first region and a separable portion including the second region and separable from the main body, and the film-forming container has the main body. It is divided into a part and the above-mentioned separated part.

Hereinafter, the film-forming container of this embodiment will be described with reference to the drawings.
25 (a) is a schematic perspective view showing an example of the film-forming container of this embodiment, and FIG. 25 (b) is an exploded perspective view of FIG. 25 (a). The film-forming container 1 has a filling portion 10 for filling a liquid or gel-like material, and the filling portion 10 has a bottom surface 10a and a side surface 10b. The bottom surface 10a of the filling portion 10 has a first region 11 and a second region 12 located at the end of the bottom surface 10a and adjacent to the first region 11, and the first region 11 and the second region 12 are separated. It is possible, and the film-forming container 1 has a main body portion 2 including a first region 11 and a separable portion 3 including a second region 12 and separable from the main body portion 2.

The film-forming container 1 is divided into a main body portion 2 and a separation portion 3.
The main body 2 has a main body bottom 21 including the first region 11 and a main body wall 22 which is a side surface 10b of the filling portion 10.
The separation portion 3 has a separation portion bottom portion 34 including the second region 12, and a separation portion wall portion 32 serving as a side surface 10b of the filling portion 10. Further, the separation portion 3 itself is the grip portion 33.

26 (a) to 26 (c) and 27 (a) to 27 (b) are process diagrams showing an example of a film forming method using the film forming container of this embodiment, and FIGS. 25 (a) to 25 (b). This is an example using the film-forming container shown in b). First, as shown in FIG. 26 (a), in the filling portion 10 of the film-forming container 1, the longitudinal direction of the filling portion 10, that is, the boundary portion between the first region 11 and the second region 12 of the bottom surface 10a of the filling portion 10 The liquid or gel-like material is supplied in a direction orthogonal to the direction along 13. That is, in the y-axis direction. Next, as shown in FIGS. 26A to 26B, the deploying means 52 such as a squeegee is placed in the lateral direction of the filling portion 10, that is, in the first region 11 and the second region 12 of the bottom surface 10a of the filling portion 10. By moving the material along the boundary portion 13, that is, in the x-axis direction, the bottom surface 10a of the filling portion 10 is spread with the liquid or gel-like material, and the filling portion 10 is filled with the liquid or gel-like material. As a result, a liquid or gel-like material film 51b is formed. Then, the liquid or gel-like material film 51b is dried to form the film 51 as shown in FIG. 26 (c). Next, as shown in FIG. 27 (a), the film 51 is removed from the main body 2 by removing the separation portion 3 from the main body 2 in the direction indicated by the arrow in FIG. 26 (c), that is, in the diagonally upward direction. Peel off. At this time, since the separating portion 3 itself is the gripping portion, the separating portion 3 is removed from the main body portion 2 by holding the separating portion 3. Subsequently, the separation portion 3 is peeled off from the membrane 51 to obtain the membrane 51 as shown in FIG. 27 (b).

When a liquid or gel-like material is formed using the film-forming container of this embodiment, the film-forming container of this embodiment is formed by having a separable part from the main body. The membrane can be easily peeled off from the membrane-forming container. Therefore, when the film is peeled off from the film-forming container, it is possible to prevent the film from cracking, breaking, wrinkling, or the like. Therefore, it is possible to improve the yield. Further, work efficiency can be improved.

In addition, when a liquid or gel-like material is formed using the film-forming container of this embodiment, the filling portion is filled with the liquid or gel-like material to form a liquid or gel-like material film. In some cases, the height of the side surface of the filling portion, that is, the depth of the filling portion can be used to obtain a material film having a uniform thickness. Thereby, a film having a uniform thickness can be obtained. Therefore, it is possible to obtain a film having good smoothness.

Further, since the film-forming container of this embodiment is divided into a main body portion and a separation portion, as compared with the first aspect, the recess of the main body portion in the first aspect becomes unnecessary, so that the main body portion Since the thickness can be reduced, the molding cost of the main body portion and the separating portion can be reduced as compared with the first aspect, and an inexpensive film-forming container can be obtained.

Hereinafter, each configuration of the film-forming container of this embodiment will be described.

(1) Separation part The separation part in this embodiment is a member that includes a second region on the bottom surface of the filling part and is separable from the main body part. Further, the film-forming container of this embodiment is divided into a main body portion and a separation portion.

As for the position of the separating portion, since the separating portion constitutes the second region on the bottom surface of the filling portion and the second region is located at the end of the bottom surface of the filling portion in the filling portion, the separating portion is formed. May be located at the end of the filling portion.

Further, the separating portion may be located at the end of the filling portion. For example, when the filling portion has a rectangular shape in a plan view, the separating portion may be located at any end of the filling portion. Specifically, when the plan view shape of the filling portion is a rectangular shape other than a square, the separating portion may be located at the end on the short side side of the filling portion, and the end on the long side side of the filling portion. It may be located in the section. In the examples shown in FIGS. 25 (a) and 25 (b), the separation portion 3 is located at the end on the short side side of the filling portion 10.

The separating portion may include a second region on the bottom surface of the filling portion and may be separable from the main body portion, and may be a separating portion bottom portion including the second region on the bottom surface of the filling portion and a side surface of the filling portion. It can have a separation part wall part. That is, the separating portion can have a separating portion bottom portion forming a second region of the bottom surface of the filling portion and a separating portion wall portion forming a side surface of the filling portion.

The plan view shape of the bottom of the separation portion is appropriately selected according to the plan view shape of the filling portion. As the plan view shape of the bottom portion of the separation portion, for example, a rectangular shape can be mentioned.

The cross-sectional shape of the bottom portion of the separation portion may be any shape as long as the cross section of the separation portion can be matched with the cross section of the main body portion. For example, in the lateral direction of the separation portion bottom 34, that is, in the y-axis direction, that is, in the yz plane, the cross-sectional shape of the separation portion bottom 34 is rectangular as shown in FIGS. 25 (a) and 25 (b). It may have an inverted trapezoidal shape as shown in FIG. 28.

As shown in FIG. 29A, for example, the thickness of the separation portion bottom 34 is the same as the thickness of the main body bottom 21 of the main body 2, and the separation portion bottom 34 and the main body bottom 21 are flush with each other. Alternatively, as shown in FIG. 29 (b), it is preferably larger than the thickness of the main body bottom 21 of the main body 2. In these cases, it is possible to prevent the film from cracking, breaking, wrinkling, etc. when the separated portion is removed from the main body when the film-formed film is peeled from the film-forming container.

The area of the bottom portion of the separation portion in a plan view is not particularly limited as long as the area is such that the separation portion can be easily removed from the main body portion when the film-formed film is peeled from the film-forming container. Above all, the area of the bottom of the separated portion in a plan view is preferably smaller than the area of the bottom of the main body in a plan view. Since the film portion formed on the separation portion may not be used as a product from the viewpoint of cleanliness, for example, the area of the bottom of the separation portion in a plan view is larger than the area of the bottom of the main body in a plan view. Due to its small size, waste of liquid or gel-like material can be reduced.
As a ratio of the area of the bottom of the separation portion in the plan view to the area of the bottom of the main body in the plan view, the area of the base of the separation portion in the plan view of the first aspect is the plan view of the portion of the bottom of the main body in the first region. Can be similar to the ratio to the area of.

Further, as for the height of the separating portion wall portion, since the separating portion wall portion constitutes the side surface of the filling portion, the height of the separating portion wall portion with respect to the bottom portion of the separating portion is usually the same as the depth of the filling portion. It can be set appropriately according to the depth of the filling portion.

The width of the wall portion of the separation portion is not particularly limited, and is appropriately set according to the size of the film-forming container of this embodiment and the like. Further, the width of the separating portion wall portion may be constant or may be partially different.

When the widths of the separating portion wall portions are partially different, for example, as shown in FIGS. 25A and 25B, of the separating portion wall portions 32, the lateral direction of the separating portion 3, that is, the bottom surface of the filling portion. The widths w21 and w22 of the parts of the separation portion wall portion 32 extending in the direction orthogonal to the direction along the boundary portion 13 of the first region 11 and the second region 12, that is, in the y-axis direction, have one width w21 as the other. It may be larger than the width w22. For example, as shown in FIGS. 26 (a) to 26 (c) and 27 (a) to 27 (b), when the filling portion is filled with the liquid or gel-like material, the liquid or gel-like material is filled in the filling portion. When the liquid or gel-like material is spread using the developing means after the supply, one width w21 is larger than the other width w22 as described above, so that the liquid or gel-like material is used by the developing means. Before spreading the material, the deploying means can be placed on the portion of the separating portion wall portion 32 having the larger width w21, and the deploying means can be stably held. Therefore, the liquid or gel-like material can be stably spread on the filled portion. Further, when the liquid or gel-like material is spread by using the developing means, from the portion of the separation portion wall portion 32 having the larger width w21 toward the portion of the separation portion wall portion 32 having the smaller width w22, When the developing means is moved, the excess liquid or gel-like material is scraped off from the portion of the separation portion wall portion 32 having the smaller width w22. At this time, since the other width w22 is smaller than the one width w21 as described above, the excess liquid or gel-like material can be easily scraped from the portion of the separation portion wall portion 32 having the smaller width w22. be able to.

Further, for example, as shown in FIGS. 25 (a) and 25 (b), with respect to the lateral direction of the separation portion 3, that is, the direction along the boundary portion 13 of the first region 11 and the second region 12 on the bottom surface of the filling portion. Of the widths w21 and w22 of the portion of the separation portion wall portion 32 extending in the orthogonal direction, that is, in the y-axis direction, when one width w21 is larger than the other width w22, the larger width w21 is the separation portion 3. It may be larger than the width w23 of the portion of the separation portion wall portion 32 extending in the longitudinal direction of, that is, the direction along the boundary portion 13 of the first region 11 and the second region 12 on the bottom surface of the filling portion, that is, the x-axis direction. As described above, the larger width w21 may be larger than the width w23 in order to place the deploying means. Further, since the widths w22 and w23 are smaller than the width w21, the material used for the film-forming container can be reduced.

On the other hand, when the width of the wall portion of the separation portion is constant, for example, when a film-forming container is manufactured by injection molding, molding is easy.

As for the position of the separating portion wall portion, since the separating portion wall portion constitutes the side surface of the filling portion, the separating portion wall portion can be extended so as to surround the filling portion.

Further, the separating portion preferably has a grip portion. When a liquid or gel-like material is formed using the film-forming container of this embodiment, when the film-formed film is peeled from the film-forming container, the grip portion of the separation portion is held and the separation portion is formed. Can be easily removed from the main body. Therefore, the formed film can be more easily peeled off from the film-forming container. Therefore, when the film is peeled off from the film-forming container, it is possible to prevent the film from cracking, breaking, wrinkling, or the like. Therefore, it is possible to improve the yield. In addition, work efficiency can be improved. Further, when the film-formed film is peeled off from the film-forming container, the cleanliness of the film can be maintained by holding the grip portion of the separation portion and removing the separation portion from the main body portion. Therefore, the film-forming container of this embodiment can be used to form a film applied to various uses.

In this aspect, the separating portion itself can be the grip portion.

Further, for example, as shown in FIG. 30, the separation portion 3 may be divisiblely connected to the main body portion 2. When the separation part is divisiblely connected to the main body part, the position of the separation part and the main body part is prevented from being displaced when the filling part is filled with a liquid or gel-like material to form a film. It can be suppressed. In this case, when the film is peeled from the film-forming container, the main body portion and the separating portion can be separated and used.

When the main body and the separating part are connected in a divisible manner, for example, as shown in FIG. 30, the connecting part between the main body 2 and the separating part 3 is thinned to make it easier to separate the main body and the separating part. Can be done.

You may be. This makes it possible to prevent the separation portion and the main body portion from being displaced when the filling portion is filled with a liquid or gel-like material to form a film.

The position of the fitting portion 35 on the separating portion side is as shown in FIGS. 31 (a) and 31 (b), for example, so that the separating portion 3 can be removed from the main body portion 2 in the diagonally upward direction D1. It is preferable that the fitting portion 35 is located. This is because it is possible to prevent an extra force from being applied to the membrane, such as stretching the membrane when the separation portion is removed from the main body portion when the membrane is peeled from the membrane-forming container.
For example, the fitting portion on the separating portion side may be located at the bottom portion of the separating portion, or may be located at the wall portion of the separating portion.

As the shape of the fitting portion 35 on the separating portion side, for example, as shown in FIGS. 31A and 31B, it is preferable that the separating portion 3 can be removed from the main body portion 2 in the diagonally upward direction D1. .. As described above, this makes it possible to prevent an extra force from being applied to the membrane, such as stretching the membrane when the separation portion is removed from the main body portion when the membrane is peeled from the membrane-forming container. Because.
For example, the shape of the separation portion side fitting portion 35 may be a concave shape as shown in FIG. 31 (a) or a convex shape as shown in FIG. 31 (b).

The cross-sectional shape of the fitting portion on the separating portion side may be, for example, as shown in FIGS. 31A and 31B, as long as the separating portion 3 can be removed from the main body portion 2 in the diagonally upward direction D1. Not limited. For example, in the cross section of the separation portion 3 in the lateral direction, that is, in the y-axis direction, that is, in the yz plane, the cross-sectional shape of the separation portion side fitting portion 35 is, for example, as shown in FIGS. 31 (a) and 31 (b). It may have a triangular shape, and although not shown, it may have a rectangular shape, a semicircular shape, a semicircular shape, a 1/4 circular shape, a 1/4 elliptical shape, a trapezoidal shape, or the like.

Further, the separating portion may be fixed to the main body portion by the fixing portion. The fixing portion is a portion for fixing the separating portion to the main body portion. In the case of forming a liquid or gel-like material using the film-forming container of this embodiment, when the liquid or gel-like material film is formed and then the liquid or gel-like material film is dried. The volume of the liquid or gel-like material film shrinks during the drying process. Since the separating portion is fixed to the main body portion by the fixing portion, it is possible to prevent the separating portion from floating from the main body portion due to the volume shrinkage of the liquid or gel-like material film during drying. ..

The fixing portion may be any as long as the separating portion can be fixed to the main body portion. For example, the separating portion can be fixed to the main body portion by using an adhesive tape, a clip, a screw or the like as the fixing portion.

Further, it is preferable that the bottom portion of the separation portion and the wall portion of the separation portion have hydrophilicity. When the bottom portion of the separation portion and the wall portion of the separation portion are hydrophilic, the filling portion can be filled with a liquid or gel-like material to satisfactorily form a liquid or gel-like material film.

The hydrophilicity of the bottom part of the separation part and the wall part of the separation part can be the same as the hydrophilicity of the base part of the separation part and the wall part of the separation part in the first aspect.

Further, the bottom portion of the separation portion and the wall portion of the separation portion may be surface-treated in order to adjust the contact angle of the surface with water. That is, the bottom portion of the separation portion and the wall portion of the separation portion may have a hydrophilic treated surface on the surface. The surface treatment can be the same as that described in the first aspect.

Further, when the membrane is heated before the membrane is peeled from the membrane-forming container, the separated portion preferably has heat resistance. The heat resistance of the separating portion can be the same as that of the separating portion in the first aspect.

The material of the separation part can be the same as the material of the separation part in the first aspect.

The material of the separation part may be the same as or different from the material of the main body part. When the material of the separating portion is the same as that of the main body portion, the separating portion and the main body portion can be molded at the same time. Further, when the material of the separating portion is different from the material of the main body portion, for example, the hydrophilicity of the separating portion and the main body portion can be made different.

(2) Main body portion The main body portion in this embodiment is a member including the first region on the bottom surface of the filling portion. Further, the film-forming container of this embodiment is divided into a main body portion and a separation portion.

It can have a main body wall portion. That is, the bottom of the main body can have a bottom of the main body that constitutes the first region of the bottom surface of the filling portion and a wall portion of the main body that constitutes the side surface of the filling portion.

The plan view shape of the bottom portion of the main body is appropriately selected according to the plan view shape of the filling portion. Examples of the plan view shape of the bottom portion of the main body include a rectangular shape and a trapezoidal shape.

Further, as for the height of the main body wall portion, since the main body wall portion constitutes the side surface of the filling portion, the height of the main body portion wall portion with respect to the bottom portion of the main body portion is usually the same as the depth of the filling portion. It can be set appropriately according to the depth of the filling portion.

The width of the wall portion of the main body is not particularly limited, and is appropriately set according to the size of the film-forming container of this embodiment. Further, the width of the main body wall portion may be constant or may be partially different.

The widths w24 and w25 of the main body wall portion 22 extending in the direction orthogonal to the direction along the boundary portion 13 of the first region 11 and the second region 12, that is, in the y-axis direction, are such that one width w24 is the other width. It may be larger than w25. For example, as shown in FIGS. 26 (a) to 26 (c) and 27 (a) to 27 (b), when the filling portion is filled with the liquid or gel-like material, the liquid or gel-like material is filled in the filling portion. When the liquid or gel-like material is spread using the developing means after the supply, one width w24 is larger than the other width w25 as described above, so that the liquid or gel-like material is spread by using the developing means. Before spreading the material of, the deploying means can be placed on the portion of the main body wall portion 22 having the larger width w24, and the deploying means can be stably held. Therefore, the liquid or gel-like material can be stably spread on the filled portion. Further, when the liquid or gel-like material is spread by using the developing means, from the portion of the main body portion wall portion 22 having the larger width w24 toward the portion of the main body portion wall portion 22 having the smaller width w25. When the deploying means is moved, the excess liquid or gel-like material is scraped off from the portion of the main body portion wall portion 22 having the smaller width w25. At this time, since the other width w25 is smaller than the one width w24 as described above, the excess liquid or gel-like material can be easily scraped off from the main body wall portion 22 having the smaller width w25. be able to.

Further, for example, as shown in FIGS. 25A and 25B, it is orthogonal to the longitudinal direction of the main body 2, that is, the direction along the boundary portion 13 of the first region 11 and the second region 12 on the bottom surface of the filling portion. Of the widths w24 and w25 of the portion of the main body wall portion 22 extending in the direction of the main body portion, that is, in the y-axis direction, when one width w24 is larger than the other width w25, the larger width w24 is shorter than the main body portion. It may be larger than the width w26 of the portion of the main body portion wall portion 22 extending in the manual direction, that is, in the direction along the boundary portion 13 of the first region 11 and the second region 12 on the bottom surface of the filling portion, that is, in the x-axis direction. As mentioned above, the larger width w24 may be larger than the width w26 in order to place the deploying means. Further, since the widths w25 and w26 are smaller than the width w24, the material used for the film-forming container can be reduced.

On the other hand, when the width of the wall portion of the main body is constant, for example, when a film-forming container is manufactured by injection molding, molding is easy.

As for the position of the main body wall portion, since the main body wall portion constitutes the side surface of the filling portion, the main body portion wall portion can be extended so as to surround the filling portion.

You may be. This makes it possible to prevent the separation portion and the main body portion from being displaced when the filling portion is filled with a liquid or gel-like material to form a film.

As for the position of the fitting portion 25 on the main body side, for example, as shown in FIGS. 31 (a) and 31 (b), the separating portion 3 can be removed from the main body portion 2 in the diagonally upward direction D1 so that the main body portion side can be removed. It is preferable that the fitting portion 25 is located. This is because it is possible to prevent an extra force from being applied to the membrane, such as stretching the membrane when the separation portion is removed from the main body portion when the membrane is peeled from the membrane-forming container.
For example, the main body side fitting portion may be located at the bottom of the main body, or may be located at the wall of the main body.

As for the shape of the fitting portion 25 on the main body side, for example, as shown in FIGS. 31A and 31B, it is preferable that the separating portion 3 can be removed from the main body 2 in the diagonally upward direction D1. .. As described above, this makes it possible to prevent an extra force from being applied to the membrane, such as stretching the membrane when the separation portion is removed from the main body portion when the membrane is peeled from the membrane-forming container. Because.
For example, the shape of the main body side fitting portion 25 may be a convex shape as shown in FIG. 31 (a) or a concave shape as shown in FIG. 31 (b).

The cross-sectional shape of the fitting portion on the main body side may be, for example, as shown in FIGS. 31 (a) and 31 (b), as long as the separating portion 3 can be removed from the main body 2 in the diagonally upward direction D1. Not limited. For example, in the longitudinal direction of the main body 2, that is, the cross section in the y-axis direction, the cross-sectional shape of the main body side fitting portion 25 may be triangular, for example, as shown in FIGS. 31 (a) and 31 (b). Often, although not shown, it may be rectangular, semicircular, semicircular, 1/4 circular, 1/4 elliptical, trapezoidal or the like.

Since the film-forming container of this embodiment is divided into a main body portion including the first region and a separation portion including the second region, the first region and the second region can be separated.

The first region is preferably larger than the second region. Since the first region formed of the main body portion is larger than the second region formed of the separating portion, waste of the liquid or gel-like material can be reduced.
The ratio of the area of the second region to the area of the first region can be the same as the ratio of the area of the second region to the area of the first region in the first aspect.

Further, it is preferable that the filling portion 10 has a groove 41 on the bottom surface 10a, for example, as shown in FIGS. 32 (a) and 32 (b). That is, it is preferable that the main body bottom portion 21 of the main body portion 2 and the separation portion bottom portion 34 of the separation portion 3 have grooves. The groove 41 is usually located around the effective film forming region 42. When the filling part has a groove located around the effective film-forming region on the bottom surface, the liquid or gel-like material film enters the groove and gets caught, so that the film is deformed such as floating and wrinkles during drying. , It is possible to suppress the occurrence of cracks. Therefore, the yield can be improved.

Hereinafter, each configuration of the film-forming container of this embodiment will be described.

(1) Separation part The separation part in this embodiment is a member that includes a second region on the bottom surface of the filling part and is separable from the main body part. Further, the separating portion in this embodiment is a film member.

As for the position of the separating portion, since the separating portion constitutes the second region on the bottom surface of the filling portion and the second region is located at the end of the bottom surface of the filling portion in the filling portion, the separating portion is formed. May be located at the end of the filling portion.

Further, the separating portion may be located at the end of the filling portion. For example, when the filling portion has a rectangular shape in a plan view, the separating portion may be located at any end of the filling portion. Specifically, when the plan view shape of the filling portion is a rectangular shape other than a square, the separating portion may be located at the end on the short side side of the filling portion, and the end on the long side side of the filling portion. It may be located in the section. In the examples shown in FIGS. 33 (a) and 33 (b), the separation portion 3 is located at the end on the short side side of the filling portion 10.

An example of the shape when the separated portion is expanded is a rectangular shape.

There is no particular limitation. Above all, it is preferable that the area in the plan view of the second region portion of the separation portion is smaller than the area in the plan view of the portion of the first region of the bottom portion of the main body portion of the main body portion. Since the film portion formed on the separation portion may not be used as a product from the viewpoint of cleanliness, for example, the area of the second region portion of the separation portion in a plan view is the main body portion of the main body portion. By being smaller than the area of the first region of the bottom in plan view, waste of liquid or gel-like material can be reduced.
The ratio of the area in the plan view of the second region portion of the separation portion to the area in the plan view of the portion of the first region at the bottom of the main body is the main body of the area in the plan view of the base portion of the separation portion in the first aspect. It can be the same as the ratio of the portion of the first region of the bottom portion to the area in a plan view.

The length of the separation portion in the longitudinal direction of the second region, that is, in the direction along the boundary between the first region and the second region on the bottom surface of the filling portion is the lateral direction of the filling portion, that is, the first region and the second region. It can be the same as the length in the direction along the boundary portion of the region, and is appropriately set according to the length of the filling portion in the direction along the boundary portion between the first region and the second region.

The length of the separation portion in the lateral direction of the second region, that is, in the direction orthogonal to the direction along the boundary between the first region and the second region on the bottom surface of the filling portion, is the lateral direction of the second region. It may be longer than the length of the second region, and is appropriately set according to the length of the second region in the lateral direction.

The separating portion preferably has a grip portion. When a liquid or gel-like material is formed using the film-forming container of this embodiment, when the film-formed film is peeled from the film-forming container, the grip portion of the separation portion is held and the separation portion is formed.

The grip portion can be easily gripped.

The area of the grip portion in a plan view is such that when the film-formed film is peeled from the film-forming container, the grip portion of the separation portion can be held and the separation portion can be easily removed from the main body portion. If so, it is not particularly limited. Above all, it is preferable that the area of the grip portion in a plan view is relatively large. The larger the plane view area of the grip portion, the easier it is to hold the grip portion and to apply force.

Further, the separating portion may be fixed to the main body portion by the fixing portion. The fixing portion is a portion for fixing the separating portion to the main body portion. In the case of forming a liquid or gel-like material using the film-forming container of this embodiment, when the liquid or gel-like material film is formed and then the liquid or gel-like material film is dried. The volume of the liquid or gel-like material film shrinks during the drying process. Since the separating portion is fixed to the main body portion by the fixing portion, it is possible to prevent the separating portion from floating from the main body portion due to the volume shrinkage of the liquid or gel-like material film during drying. ..

The fixing portion may be any as long as the separating portion can be fixed to the main body portion, and for example, the separating portion can be fixed by using an adhesive tape, a clip or the like as the fixing portion.

Moreover, it is preferable that the separating portion has hydrophilicity. When the separating portion has hydrophilicity, the filling portion can be filled with a liquid or gel-like material to satisfactorily form a liquid or gel-like material film.

It can have a main body wall portion. That is, the bottom of the main body can have a bottom of the main body that constitutes the first region of the bottom surface of the filling portion and a wall portion of the main body that constitutes the side surface of the filling portion.

The plan view shape of the bottom portion of the main body is appropriately selected according to the plan view shape of the filling portion. As the plan view shape of the bottom portion of the main body, for example, a rectangular shape can be mentioned.

Further, as for the height of the main body wall portion, since the main body wall portion constitutes the side surface of the filling portion, the height of the main body portion wall portion with respect to the bottom portion of the main body portion is usually the same as the depth of the filling portion. It can be set appropriately according to the depth of the filling portion.

The width of the wall portion of the main body is not particularly limited, and is appropriately set according to the size of the film-forming container of this embodiment. Further, the width of the main body wall portion may be constant or may be partially different.

When the widths of the main body wall portions are partially different, for example, as shown in FIGS. 33 (a) and 33 (b), of the main body portion wall portions 22, the longitudinal direction of the main body portion 2, that is, the bottom surface of the filling portion 10 The widths w31 and w32 of the main body wall portion 22 extending in the direction orthogonal to the direction along the boundary portion 13 of the first region 11 and the second region 12, that is, in the y-axis direction, have one width w31 as the other. It may be larger than the width w32. For example, when filling the filling part with a liquid or gel-like material, when the liquid or gel-like material is supplied to the filling part and then the liquid or gel-like material is spread by using a developing means, the above-mentioned As described above, since one width w31 is larger than the other width w32, the deploying means is applied to the portion of the main body wall portion 22 having the larger width w31 before spreading the liquid or gel-like material using the deploying means. Can be placed, and the deployment means can be stably held. Therefore, the liquid or gel-like material can be stably spread on the filled portion. Further, when the liquid or gel-like material is spread by using the developing means, from the portion of the main body portion wall portion 22 having the larger width w31 toward the portion of the main body portion wall portion 22 having the smaller width w32, When the deploying means is moved, the excess liquid or gel-like material is scraped off from the portion of the main body portion wall portion 22 having the smaller width w32. At this time, since the other width w32 is smaller than the one width w31 as described above, the excess liquid or gel-like material can be easily scraped off from the portion of the main body wall portion 22 having the smaller width w31. be able to.

Further, for example, as shown in FIGS. 33 (a) and 33 (b), with respect to the longitudinal direction of the main body 2, that is, the direction along the boundary portion 13 of the first region 11 and the second region 12 on the bottom surface of the filling portion 10. Of the widths w31 and w32 of the portion of the main body wall portion 22 extending in the orthogonal direction, that is, in the y-axis direction, when one width w31 is larger than the other width w32, the larger width w32 is the main body portion. It is larger than the widths w33 and w34 of the main body wall portion 22 extending in the lateral direction, that is, the direction along the boundary portion 13 of the first region 11 and the second region 12 on the bottom surface of the filling portion 10, that is, the x-axis direction. May be good. As described above, the larger width w31 may be larger than the widths w33 and w34 in order to place the deploying means. Further, since the widths w32, w33, and w34 are smaller than the width w31, the material used for the film-forming container can be reduced.

On the other hand, when the width of the wall portion of the main body is constant, for example, when a film-forming container is manufactured by injection molding, molding is easy.

As for the position of the main body wall portion, since the main body wall portion constitutes the side surface of the filling portion, the main body portion wall portion can be extended so as to surround the filling portion.

Further, it is preferable that the bottom portion of the main body portion and the wall portion of the main body portion have hydrophilicity. When the bottom portion of the main body and the wall portion of the main body are hydrophilic, the filling portion can be filled with a liquid or gel-like material to satisfactorily form a liquid or gel-like material film.

The hydrophilicity of the bottom of the main body and the wall of the main body can be the same as the hydrophilicity of the separation portion described above.

Further, the bottom of the main body and the wall of the main body may be surface-treated in order to adjust the contact angle of the surface with water. That is, the bottom of the main body and the wall of the main body may have a hydrophilic treated surface on the surface. Since the surface treatment is the same as that described above, the description thereof will be omitted here.

Further, when the film is heated before the film is peeled off from the film-forming container, the main body preferably has heat resistance. The heat resistance of the main body portion can be the same as the heat resistance of the separation portion described above.

As the material of the main body, a liquid or gel-like material can be filled in the filling portion composed of the main body and the separating portion to form a film, and after the film formation, the film is formed from the main body. The material is not particularly limited as long as it can be peeled off, and can be appropriately selected depending on the type of liquid or gel-like material, the use of the film, and the like.

The material of the main body can be the same as the material of the separation part described above.

(3) Filling part The filling part in this embodiment is a part for filling a liquid or gel-like material, and has a bottom surface and a side surface. Further, the bottom surface of the filling portion has a first region and a second region located at the end of the bottom surface and adjacent to the first region, and these first region and the second region are separable. ing. In this embodiment, since the separating portion is a film member, the first region and the second region can be separated.

The first region is preferably larger than the second region. Since the first region formed of the main body portion is larger than the second region formed of the separating portion, waste of the liquid or gel-like material can be reduced.

Therefore, the yield can be improved.

As the position of the groove, it is sufficient that the groove is located around the effective film forming region. Above all, when the plan view shape of the effective film-forming region is rectangular, it is preferable that the grooves are located at least on two opposite sides of the four sides of the effective film-forming region. Further, when the plan view shape of the effective film forming region is a rectangular shape other than a square, for example, as shown in FIGS. 35 (a) and 35 (b), the groove 41 is the length of the four sides of the effective film forming region 42. It is preferably located at least on two sides of the side. This is because it is considered that the length of the groove can be increased by locating the groove on the long side, and the effect of suppressing the floating of the film during drying is enhanced. In particular, as shown in FIG. 35 (b), for example, the groove 41 is preferably located on three sides of the effective film forming region 42 other than the side on the second region 12 side.

The position, length, depth, width, shoulder angle, plan view shape, and the like of the groove can be the same as those of the groove in the first aspect, and thus the description thereof will be omitted here.

Further, by making the width of the separating portion, which is a film member, shorter than the width of the filling portion, a gap can be provided between the separating portion and the side surface of the filling portion, and the gap can function as the groove.

Further, the plan view shape and the like of the filling portion can be the same as that of the filling portion in the first aspect, and thus the description thereof is omitted here.

The filling portion has a groove on the bottom surface, and the groove serves as an effective region of the film formed in the filling portion (hereinafter, referred to as an effective film forming region). .) Is located around.

Conventionally, as a method for forming a film of a liquid or gel-like material, for example, a method of pouring a liquid or gel-like material into a mold, solidifying the material, and then peeling the formed film from the mold is known.
In the film forming method using a mold as described above, when a liquid or gel-like material is poured into a mold and then dried for solidification, the film may be deformed or cracked such as floating or wrinkles. Yes, the decrease in yield has become a problem.

The filling portion 10 has a groove 41 on the bottom surface 10a, and the groove 41 is located around the effective film forming region 42.

The film-forming container 1 has a bottom portion 61 which is a bottom surface 10a of the filling portion 10 and a wall portion 62 which is a side surface 10b of the filling portion 10.

37 (a) to 37 (b) are process diagrams showing an example of a film forming method using the film forming container of this embodiment. As shown in FIG. 37 (a), the filling portion 10 is filled with a liquid or gel-like material to form a liquid or gel-like material film 51b, and then as shown in FIG. 37 (b), the liquid is liquid. Alternatively, the gel-like material film 51b is dried to remove the solvent, and the film 51 is obtained.

In the present embodiment, the filling portion has a groove located around the effective film forming region on the bottom surface, so that the liquid or gel-like material film gets caught in the groove and floats when the film is dried. , Deformation such as wrinkles, cracks, etc. can be suppressed. Therefore, the yield can be improved.

Further, when a liquid or gel-like material is formed by using the film-forming container of the present embodiment, the filling portion is filled with the liquid or gel-like material to form a liquid or gel-like material film. In this case, the height of the side surface of the filling portion, that is, the depth of the filling portion can be utilized to obtain a material film having a uniform thickness. Thereby, a film having a uniform thickness can be obtained. Therefore, it is possible to obtain a film having good smoothness.

Hereinafter, each configuration of the film-forming container of this embodiment will be described.

1. 1. Filling section The filling section in the present embodiment is a portion for filling a liquid or gel-like material, and has a bottom surface and side surfaces. Further, the filling portion has a groove on the bottom surface, and the groove is located around the effective film forming region.

As for the position of the groove, the groove may be located around the effective film forming region. Above all, when the plan view shape of the effective film forming region is rectangular, for example, as shown in FIGS. 36 (a) to 36 (c), the groove 41 is formed on two opposite sides of the four sides of the effective film forming region 42. It is preferably located at least in. Further, when the plan view shape of the effective film forming region is a rectangular shape other than a square, for example, as shown in FIGS. 36 (a) to 36 (c), the groove 41 is the length of the four sides of the effective film forming region 42. It is preferably located on at least two sides of the side. This is because it is considered that the length of the groove can be increased by locating the groove on the long side, and the effect of suppressing the floating of the film during drying is enhanced. In particular, as shown in FIGS. 38 (a) to 38 (c), for example, the grooves 41 are preferably located on the four sides of the effective film forming region 42.
38 (a) is a schematic plan view showing an example of the film-forming container of this embodiment, FIG. 38 (b) is a sectional view taken along line AA of FIG. 38 (a), and FIG. 38 (c) is a sectional view taken along the line AA. It is sectional drawing BB of FIG. 38 (a).

The position, length, depth, width, shoulder angle, plan view shape, and the like of the groove can be the same as those of the groove in the first aspect of the first embodiment, and thus the description thereof is omitted here. To do.

Further, since the plan-view shape of the filling portion can be the same as that of the filling portion in the first aspect of the first embodiment, the description thereof is omitted here.

2. 2. Bottom and Wall The film-forming container of this embodiment can have a bottom that is the bottom surface of the filling portion and a wall portion that is the side surface of the filling portion.

The plan view shape of the bottom portion can usually be the same as the plan view shape of the filling portion, and is appropriately selected according to the plan view shape of the filling portion. As the plan view shape of the bottom portion, for example, a rectangular shape can be mentioned.

Further, as for the height of the wall portion, since the wall portion constitutes the side surface of the filling portion, the height of the wall portion with respect to the bottom portion can usually be the same as the depth of the filling portion, and the depth of the filling portion. It is set as appropriate according to the situation.

The width of the wall portion is not particularly limited, and is appropriately set according to the size of the film-forming container of this embodiment and the like. Further, the width of the wall portion may be constant or may be partially different.

It may be larger than w44. For example, when filling the filling part with a liquid or gel-like material, when the liquid or gel-like material is supplied to the filling part and then the liquid or gel-like material is spread by using a developing means, the above-mentioned Since one width w41 is larger than the other widths w42 to w44, the deploying means is placed on the wall portion 62 having a large width w41 before spreading the liquid or gel-like material using the deploying means. It is possible to stably hold the deploying means. Therefore, the liquid or gel-like material can be stably spread on the filled portion. Further, when the liquid or gel-like material is spread by using the developing means, if the developing means is moved from the portion of the wall portion 62 having a width w41 toward the portion of the wall portion 62 having a small width w42, a surplus is generated. The liquid or gel-like material will be scraped off from the portion of the wall portion 62 having a small width w42. At this time, since one width w41 is larger than the other width w42 as described above, the excess liquid or gel-like material can be easily scraped from the portion of the wall portion 62 having a small width w42.

Further, for example, as shown in FIGS. 38 (a) and 38 (b), when one of the widths w41 to w44 of each side of the wall portion 62 is larger than the other widths w42 to w44, the larger width w41 The width w42 of the portion of the wall portion 62 facing the portion of the wall portion 62 of the above may be smaller than the widths w43 and w44 other than the large width w41. As described above, the width w42 may be smaller than the widths w43 and w44 in order to facilitate scraping of excess liquid or gel-like material. Further, since the widths w42, w43, and w44 are smaller than the width w41, the material used for the film-forming container can be reduced.

On the other hand, when the width of the wall portion is constant, for example, when a film-forming container is manufactured by injection molding, molding is easy.

As for the position of the wall portion, since the wall portion constitutes the side surface of the filling portion, the wall portion can be extended so as to surround the filling portion.

Further, it is preferable that the bottom portion and the wall portion have hydrophilicity. When the bottom portion and the wall portion have hydrophilicity, the filling portion can be filled with a liquid or gel-like material to satisfactorily form a liquid or gel-like material film.

Further, the bottom portion and the wall portion may be surface-treated in order to adjust the contact angle of the surface with water. That is, the bottom and the wall may have a hydrophilic treated surface on the surface. Since the surface treatment is the same as that described in the first aspect of the first embodiment, the description thereof will be omitted here.

Further, when the film is heated before the film is peeled from the film-forming container, the film-forming container preferably has heat resistance. The heat resistance of the film-forming container can be the same as the heat resistance of the separation portion in the first aspect of the first embodiment.

As the material of the film-forming container, a liquid or gel-like material can be filled in the filling portion to form a film, and after the film-forming, the film can be peeled off from the film-forming container.
