JP, 2016-010919, A

  However, in the conventional forming head, the forming piece can not be inclined to the forming surface, and there is a limit in creating a new form of the forming piece.

  This invention is made in view of the said problem, Comprising: It aims at providing the modeling head which can make a modeling piece into the attitude | position which inclined with respect to the modeling surface.

  The present invention adopts the following means in order to solve the above problems. That is, the shaping head of the present invention is provided above the discharge hole through which the contents are discharged, and has a top wall portion in which a forming hole penetrating in the vertical direction is formed, and among the top wall portions It is a modeling head by which the modeling piece formed when contents pass through the above-mentioned forming hole is discharged on the forming surface which turns upwards, and the above-mentioned forming hole is the up-and-down direction in the longitudinal section view along the up-and-down direction In the longitudinal sectional view, at least a portion of each of the first opposing surface and the second opposing surface has a first opposing surface and a second opposing surface which are opposed to each other in a transverse direction orthogonal to each other. The inclined surface extends from the supply surface side facing downward to the modeling surface side and to one side in the lateral direction, and in the longitudinal sectional view, the first opposing surface is the second opposing surface. Located on one side of the lateral direction, of the forming hole End opening, characterized in that in opposition to the inclined surface and the vertical direction of the second facing surface over the entire.

In the present invention, the forming hole has a first opposing surface and a second opposing surface facing each other in the lateral direction in the longitudinal sectional view, and at least a part of each of the first opposing surface and the second opposing surface However, since it is an inclined surface inclined in the same direction with respect to the vertical direction, the content that has flowed into the forming hole from the lower end opening on the supply surface side is the first opposing surface by the inclined surface of the second opposing surface. And each inclined surface of the second opposing surface can flow in a direction inclined with respect to the vertical direction, and the inclined surface of the first opposing surface allows the content to flow toward the modeling surface as it is Can. Thus, the content can be formed on the shaped piece in a posture in which the inclined surfaces of the first opposing surface and the second opposing surface are inclined with respect to the vertical direction.
In particular, since the lower end opening of the forming hole is vertically opposed to the inclined surface of the second opposing surface over the entire area, the content flowing into the forming hole from the lower end opening on the supply surface side is straight upward. It is possible to prevent the flow from directly reaching the formed surface. Therefore, it becomes possible to make the flow of the whole contents which flowed in the forming hole into the above-mentioned inclined direction, and the posture of the modeling piece on the modeling surface can be surely inclined to the above-mentioned inclined direction. .

  Here, in the longitudinal sectional view, the lower end edge of the inclined surface of the first opposing surface and the upper end edge of the inclined surface of the second opposing surface may be opposed in the vertical direction.

In this case, since the lower end edge of the inclined surface of the first opposing surface and the upper end edge of the inclined surface of the second opposing surface oppose each other in the vertical direction in the vertical sectional view, It becomes possible to mold with a moving mold and prevent the complication of the structure of the mold for molding the top wall.
Further, since the lower end edge of the inclined surface of the first opposing surface and the upper end edge of the inclined surface of the second opposing surface oppose each other in the vertical direction in the longitudinal sectional view, it flows into the forming hole from the lower end opening It is possible to suppress backflow of the contents, and the shaped piece can be formed with high accuracy.

  In addition, the formed hole is formed in a radially elongated long hole shape intersecting with the central axis of the top wall portion in a plan view as viewed from the upper and lower direction, and spaced in the circumferential direction around the central axis A plurality of arranged pieces, the first opposing surface and the second opposing surface face in the circumferential direction, and a plurality of shaped pieces formed by the contents from the discharge holes respectively passing through the plurality of forming holes, The shaped surface may be combined to form a shaped object.

In this case, the forming holes are formed in the shape of long holes in the radial direction, and are spaced apart in the circumferential direction, and the first opposing surface and the second opposing surface face in the circumferential direction. It is possible to form a shaped object by combining the shaped pieces in the circumferential direction with the same orientation in the circumferential direction and forming a shaped object, and it is possible to obtain a shaped object in the form of being twisted in the circumferential direction.
In addition, since the forming holes are formed in the shape of long holes extending in the radial direction and are arranged in plural at intervals in the circumferential direction, supporting mutually adjacent forming pieces in the circumferential direction It becomes possible, and it is possible to form a high-precision shaped object while suppressing the deformation of the shaped piece.

  Further, in this configuration, the inclination angle of the inclined surface in each of the first opposing surface and the second opposing surface with respect to the central axis is minimized at a portion located at the inner end portion in the radial direction. It may become gradually larger as it goes from the inner side to the outer side in the radial direction so as to be maximum at the portion located at the end.

  In this case, it is possible to form a shaped piece in which the inclination angle with respect to the vertical direction gradually increases from the inner side toward the outer side in the radial direction. Therefore, while being able to form the three-dimensional object excellent in aesthetics, it is possible to support mutually the modeling pieces which are mutually adjacent in the circumferential direction reliably.

  The thickness of the top wall may be 0.5 mm or more and 3.0 mm or less.

In this case, since the thickness of the top wall portion is 0.5 mm or more and 3.0 mm or less, the top wall portion can be formed with high accuracy while suppressing the complication of the mold structure.
If the thickness of the top wall portion is less than 0.5 mm, for example, the thickness of the top wall portion becomes too thin, and the lengths of the inclined surfaces of the first opposing surface and the second opposing surface Not only the performance can not be ensured, but also the die for molding the forming hole may be too small, or the strength of the top wall may be reduced.
If the thickness of the top wall exceeds 3.0 mm, for example, a sink may occur in the top wall.

  In addition, a plurality of the forming holes are formed in the top wall portion, and the exterior portion includes the top wall portion and a peripheral wall portion extending downward from the outer peripheral edge of the top wall portion, and is disposed in the exterior portion. And a middle plate defining a diffusion chamber for diffusing the contents from the discharge hole in the lateral direction and supplying the formed hole to the top wall portion with the supply surface of the top wall portion, and the diffusion chamber A plurality of shaped pieces formed by passing the contents from each of the plurality of formed holes separately may be combined in the shaped surface to form a shaped article.

  In this case, since the diffusion chamber is provided between the top wall portion and the inner plate, the contents are prevented from being concentrated and flowing into a specific part of the plurality of forming holes, and each forming hole is formed. The contents can be supplied with less variation. In this way, it is possible to supply an appropriate amount of content to each of the forming holes, while preventing the contents from being excessively or excessively supplied to the forming holes. Therefore, it becomes possible to form a modeling piece formed of each forming hole with sufficient accuracy, and a modeled object can be formed with high accuracy.

  According to the present invention, it is possible to make the shaped piece in a posture inclined with respect to the shaped surface.

The convex portions 15 d extend in the vertical direction, and a plurality of convex portions 15 d are formed at intervals in the circumferential direction.
At the lower end portion of the peripheral wall portion 15a of the exterior portion 15, a fitting portion 15e that protrudes inward in the radial direction is formed. The fitting portion 15 e is undercut and fitted to the fitting portion 23 c of the fixing member 13. Thereby, the upward movement of the exterior portion 15 with respect to the fixing member 13 is restricted. Further, the lower end opening edge of the peripheral wall portion 15 a of the exterior portion 15 is in contact with or close to the upper surface of the flange portion 63 b of the fixing member 13.

The inner plate 16 is, as shown in FIG. 1, an upper standby position in which the upper surface of the plate main body 30 abuts or approaches the supply surface 28, and as shown in FIG. A diffusion chamber 35 is formed spaced downward from 28 and the stem 19 is lowered to lower the discharge position for supplying the contents from the upper end opening 19a of the stem 19 into the diffusion chamber 35, Move up and down.
The diffusion chamber 35 is disposed coaxially with the container axis O. The diffusion chamber 35 is formed in a flat shape that is larger in the radial direction than in the vertical direction. A part of the wall surface of the diffusion chamber 35 is formed by the supply surface 28 and the upper surface of the plate body 30.

The plate body 30 is fitted in the exterior portion 15, and the outer peripheral edge slides in the vertical direction on the inner circumferential surface of the exterior portion 15. The upper surface of the plate main body 30 is in contact with or close to the supply surface 28 of the exterior portion 15 by the upward biasing force of the biasing member 21 described later. In plan view, the plate body 30 and the supply surface 28 are formed in the same shape and size as each other.
A communication hole 34 penetrating in the vertical direction is formed in the plate body 30. The communication hole 34 is arranged coaxially with the container axis O. The core 25 of the exterior 15 is inserted into the communication hole 34. The inner diameter of the communication hole 34 is smaller than the outer diameter of the stem 19.

The core 25 projects into the diffusion chamber 35.

  A guide cylinder 31 coaxially arranged with the container axis O and extending downward is formed in the plate body 30. The inner diameter of the guide cylinder 31 is larger than the inner diameter of the communication hole 34, and the guide cylinder 31 surrounds the communication hole 34 from the outside in the radial direction. When the inner tray 16 is lowered, the upper end of the stem 19 enters the guide cylinder 31. The lower end portion of the inner peripheral surface of the guide cylinder 31 gradually expands in diameter as it goes downward. Thus, when the inner tray 16 is lowered, the stem 19 smoothly enters the guide cylinder 31.

The inner conversion cylindrical portion 32 surrounds the guide cylinder 31 from the outer side in the radial direction. The lower end portion of the inner conversion cylindrical portion 32 is located below the lower end portion of the guide cylinder 31.

  In addition, the form for rotating the exterior part 15 and the inside plate 16 integrally is not restricted to the said convex part 15d and the recessed part 30a. For example, the number of protrusions 15 d and the number of recesses 30 a may be changed as appropriate. Alternatively, a recess may be formed in the exterior portion 15 and a protrusion to be engaged with the recess may be formed in the inner tray 16.

  As shown in FIGS. 1 and 6, a biasing member 21 such as a coil spring is disposed between the fixing member 13 and the inner plate 16. The biasing member 21 is disposed in the vertical gap between the container body 11 and the inner plate 16. The biasing member 21 is in a state in which the lower end abuts on the upper surface of the receiving portion 54 of the fixing member 13 and the upper end abuts on the lower surface of the plate main body 30 when the middle plate 16 is positioned at the discharge position. In the vertical direction. Thereby, the biasing member 21 biases the middle plate 16 located at the discharge position upward. In the case where a metal coil spring is used as the biasing means, it is possible to apply a sufficient upper biasing force to the inner plate 16, and the contents in the diffusion chamber 35 are reliably pushed to the modeling surface 27. be able to.

  Here, in the present embodiment, a conversion mechanism 37 is provided which converts the rotational movement of the outer cover 15 and the inner tray 16 about the container axis O with respect to the container body 11 into the vertical movement of the inner tray 16. The conversion mechanism 37 includes a sliding projection 42 provided on one of the inner tray 16 and the container body 11 and a guide projection 43 provided on the other.

  In the illustrated example, the sliding protrusion 42 protrudes radially outward from the outer peripheral surface of the inner conversion cylindrical portion 32, and the guide protrusion 43 is an inner periphery of the outer conversion cylindrical portion 55 of the container body 11. It projects radially inward from the surface. The guide projection 43 is formed from the upper end portion of the outer conversion cylindrical portion 55 to the central portion in the vertical direction. The upper end portion of the sliding projection 42 is located below the upper end portion of the guide projection 43.

  As shown in FIG. 5, the guide protrusion 43 gradually extends from the lower end portion of the first vertical surface 43 a extending in the vertical direction and the lower end of the first vertical surface 43 a upward from the first vertical surface 43 a in the circumferential direction And a first inclined surface 43b spaced apart from each other, and formed in a substantially triangular shape having a corner projecting downward. The lower end of the first vertical surface 43a and the lower end of the first inclined surface 43b are connected downward via a curved surface 43c.

The sliding projection 42 has a second vertical surface 42a extending in the vertical direction, and a second inclined surface gradually separating from the second vertical surface 42a toward the other side in the circumferential direction as going downward from the upper end of the second vertical surface 42a. It has a surface 42 b and is formed in a substantially triangular shape having a corner projecting upward. The upper end of the second vertical surface 42a and the upper end of the second inclined surface 42b are connected upward via a curved surface 42c.
The sliding projection 42 is smaller than the guide projection 43 as a whole, and is formed in a shape substantially similar to the guide projection 43. The angle formed by the first vertical surface 43a and the first inclined surface 43b is equal to the angle formed by the second vertical surface 42a and the second inclined surface 42b.

The first inclined surface 43 b and the second inclined surface 42 b allow the other side rotation of the inner tray 16 in the circumferential direction with respect to the container body 11. When the second inclined surface 42b slides on the first inclined surface 43b, the second inclined surface 42b abuts on the first inclined surface 43b over the entire area.
The first vertical surface 43 a and the second vertical surface 42 a and the upward biasing force of the biasing member 21 to the inner plate 16 restrict rotation of the inner plate 16 in the circumferential direction with respect to the container body 11. At this time, the second vertical surface 42a abuts on the first vertical surface 43a over the entire area.

Thus, the sliding protrusion 42, the guide protrusion 43, and the biasing member 21 constitute a ratchet mechanism that allows rotation of the inner plate 16 about the container axis O relative to the container body 11 in only one direction. . In the illustrated example, clockwise rotation of the inner tray 16 with respect to the container body 11 is permitted, and counterclockwise rotation is restricted in top view.
The ratchet mechanism may be configured to allow counterclockwise rotation of the inner tray 16 with respect to the container body 11 in top view and to restrict clockwise rotation.

FIG. 4 is a top view of the fixing member 13 and the shape of the inner tray 16 viewed downward from the XX section line shown in FIG. 1 is indicated by a two-dot chain line.
A plurality of guide protrusions 43 are formed on the inner peripheral surface of the outer conversion cylindrical portion 55 at equal intervals in the circumferential direction. The size in the circumferential direction of a portion (hereinafter referred to as a relief portion) 55 e located between the guide protrusions 43 adjacent to each other in the circumferential direction on the inner side of the outer conversion cylindrical portion 55 is the circumferential direction of the sliding protrusion 42 Greater than the size of For this reason, in a state where the sliding projection 42 is positioned at the relief portion 55e, between at least one of the two guide projections 43 adjacent to each other in the circumferential direction and the sliding projection 42, There is a circumferential gap. As a result, when an excessively large rotational force is applied to the inner plate 16, for example, it is possible to prevent the sliding projection 42 from continuously crossing over the plurality of guide projections 43 in the circumferential direction, and the content It is possible to prevent the thing from being discharged continuously.

  A plurality of sliding protrusions 42 are formed on the outer peripheral surface of the inner conversion cylindrical portion 32 at equal intervals in the circumferential direction. The sliding projections 42 are provided in the same number as the guide projections 43 (four in the illustrated example). The number of the sliding projections 42 may not be the same as the number of the guiding projections 43, and may be smaller than that of the guiding projections 43, for example.

And in this embodiment, the forming hole 26 has the 1st opposing surface 38 and the 2nd opposing surface 39 which mutually oppose in the said horizontal direction, as FIG. 3 shows, in the longitudinal cross-sectional view in alignment with an up-down direction. There is.
The first facing surface 38 and the second facing surface 39 face in the circumferential direction as shown in FIG. In the longitudinal sectional view, at least a part of each of the first opposing surface 38 and the second opposing surface 39 is an inclined surface extending from the supply surface 28 side toward the modeling surface 27 toward one side in the circumferential direction. ing. In the longitudinal sectional view, at least the lower portion of the second opposing surface 39 on the supply surface 28 side is an inclined surface extending from the supply surface 28 side toward the modeling surface 27 toward one side in the circumferential direction, At least the upper portion of the facing surface 38 on the side of the modeling surface 27 is an inclined surface extending from the supply surface 28 toward the modeling surface 27 toward one side in the circumferential direction.
In the illustrated example, in the longitudinal sectional view, the entire area in the vertical direction in each of the first opposing surface 38 and the second opposing surface 39 is a slope extending toward one side in the circumferential direction from the supply surface 28 toward the modeling surface 27 The first opposing surface 38 is located on one side of the second opposing surface 39 in the circumferential direction. In the longitudinal sectional view, the inclined surfaces of the first opposing surface 38 and the second opposing surface 39 are parallel to each other. As shown in FIG. 3, in the longitudinal sectional view, the upper end opening 26 a of the forming hole 26 vertically opposes the first opposing surface 38 over the entire area, and the lower end opening 26 b of the forming hole 26 extends over the entire area It opposes the opposing surface 39 in the up-down direction.

  In the longitudinal sectional view, the lower end edge 24a of the inclined surface of the first opposing surface 38 and the upper end edge 24b of the inclined surface of the second opposing surface 39 are opposed in the vertical direction. In the longitudinal sectional view, the lower end edge 24a of the inclined surface of the first opposing surface 38 and the upper end edge 24b of the inclined surface of the second opposing surface 39 are corner portions sharpened at an acute angle. The lower end edge 24a of the inclined surface of the first opposing surface 38 and the upper end edge 24b of the inclined surface of the second opposing surface 39 may be appropriately changed, for example, to be curved or planar in the longitudinal sectional view. . In addition, the predetermined lengths in the circumferential direction of each of the first opposing surface 38 and the second opposing surface 39 may be opposed in the vertical direction.

  The forming hole 26 has a rectangular shape as viewed in the vertical direction. The forming hole 26 is formed in the shape of a long hole which is long in the radial direction in a plan view as viewed from the vertical direction. The circumferential width of the forming hole 26 gradually increases as it goes from the inner side to the outer side in the radial direction. The forming hole 26 has a convex curved shape toward one side in the circumferential direction in a plan view viewed from the up and down direction. The inclination angles θ1 and θ2 of the first and second opposing surfaces 38 and 39 with respect to the vertical direction of the inclined surface are the smallest at the portion located at the inner end in the radial direction and are located at the outer end in the radial direction It becomes gradually larger as it goes from the inner side to the outer side in the radial direction so as to be the largest at the part. In the top wall portion 24, in the portions where the radial distances from the container axis O are the same, the inclination angles θ1 and θ2 of the inclined surfaces of the first opposing surface 38 and the second opposing surface 39 are equal to each other.

The circumferential width of the forming hole 26 gradually becomes wider as it goes from the lower side to the upper side. The opening area of the upper end opening 26 a of the forming hole 26 is larger than the opening area of the lower end opening 26 b of the forming hole 26.
A plurality of forming holes 26 are formed in the top wall portion 24 at intervals in the circumferential direction. The plurality of forming holes 26 are disposed at the top wall portion 24 at equal intervals in the circumferential direction. In the shaped surface 27 of the top wall portion 24, at the same radial distance from the container axis O, the circumferential width of the upper end opening 26a of the formed hole 26 is the upper end of the formed hole 26 adjacent to each other in the circumferential direction It is equal to the distance between the openings 26a. In the supply surface 28 of the top wall portion 24, at the same radial distance from the container axis O, the circumferential width of the lower end opening 26b of the forming hole 26 is the lower end of the forming hole 26 adjacent to each other in the circumferential direction It is smaller than the distance between the openings 26b.

  Next, the operation of the discharge container 1 configured as described above will be described.

  When the exterior portion 15 is rotated with respect to the container body 11 toward the other side in the circumferential direction around the container axis O, the inner plate 16 rotates around the container axis O with respect to the fixing member 13 integrally with the exterior portion 15 The first inclined surface 43b and the second inclined surface 42b abut in the circumferential direction. At this time, the second inclined surface 42b abuts on the first inclined surface 43b over the entire area. When the exterior portion 15 is further rotated continuously, the sliding projection 42 descends along the first inclined surface 43b as shown by the arrow M1 in FIG. As a result, the inner plate 16 descends against the upward biasing force of the biasing member 21, and the locking portion 36 of the inner plate 16 lowers the stem 19 and diffusion between the inner plate 16 and the exterior portion 15 While the internal volume of the chamber 35 is increased, the contents are discharged to the shaped surface 27 through the upper end opening 19a of the stem 19, the communication hole 34, the diffusion chamber 35, and the forming hole 26.

  In the above process, the contents that have flowed into the diffusion chamber 35 flow up and down on the outer peripheral surface of the core 25 and are held by the core 25. At this time, the contents are held by, for example, the core 25 in a circular shape centered on the core 25 in plan view. When the supply amount of the content to the core 25 increases with the increase of the discharge amount from the stem 19 of the content, the content grows on the core 25 and gradually expands outward in the radial direction. . As a result, in addition to the fact that the diffusion chamber 35 is formed in a flat shape as described above, the contents supplied into the diffusion chamber 35 are diffused in the radial direction and supplied to the plurality of forming holes 26. . As shown in FIGS. 7 and 8, the contents having passed through the plurality of forming holes 26 are discharged to the shaped surface 27 to form a plurality of shaped pieces Z1, and the shaped pieces Z1 are combined to form a shaped object Z. Is formed.

When the exterior portion 15 is further continuously rotated, the sliding projection 42 reaches the lower end portion of the first inclined surface 43 b of the guide projection 43 as shown by the arrow M 2 in FIG. It gets over to the other side of and reaches the relief 55e. In the relief portion 55e, since the upward movement of the sliding protrusion 42 is permitted, the upper plate 16 is raised to the standby position by the upward biasing force of the biasing member 21. At this time, the upper surface of the plate body 30 abuts on or approaches the supply surface 28 of the exterior portion 15, whereby the internal volume of the diffusion chamber 35 decreases or disappears, and the content remaining in the diffusion chamber 35 diffuses. It is discharged from the chamber 35 through the forming hole 26 to the shaped surface 27.
When the content is to be discharged again, by performing the operation of rotating the exterior portion 15 in the same direction, the above-described operation is repeated, and the content can be repeatedly discharged.

  As described above, according to the discharge container 1 of the present embodiment, the forming hole 26 has the first opposing surface 38 and the second opposing surface 39 in the longitudinal cross-sectional view, and these first opposing surfaces 38 Since at least a part of each of the second opposing surfaces 39 is an inclined surface inclined in the same direction with respect to the vertical direction, the contents flowing into the forming hole 26 from the lower end opening 26 b on the supply surface 28 side The inclined surfaces of the second opposing surface 39 allow the inclined surfaces of the first opposing surface 38 and the second opposing surface 39 to flow in a direction inclined with respect to the vertical direction, and The inclined surface allows the contents to flow toward the modeling surface 27 as it is. Thereby, as shown in FIG. 7 and FIG. 8, the shaped piece Z1 of the posture in which the inclined surfaces of the first opposing surface 38 and the second opposing surface 39 are inclined with respect to the vertical direction, as shown in FIGS. 7 and 8. Can be formed.

  In particular, since the lower end opening 26b of the forming hole 26 vertically opposes the inclined surface of the second opposing surface 39 over the entire area, the content that has flowed into the forming hole 26 from the lower end opening 26b on the supply surface 28 side Can be prevented from flowing straight upward and reaching the shaped surface 27 directly. Therefore, the flow of the entire contents flowing into the forming hole 26 can be made to the above-mentioned inclined direction, and the posture of the shaped piece Z1 on the modeling surface 27 is surely inclined to the above-mentioned inclined direction. be able to.

Further, since the lower end edge 24a of the inclined surface of the first opposing surface 38 and the upper end edge 24b of the inclined surface of the second opposing surface 39 oppose each other in the vertical direction in the longitudinal sectional view, It becomes possible to mold with a vertically moving mold, and it is possible to prevent the structure of the mold for molding the top wall 24 from being complicated.
Further, since the lower end edge 24a of the inclined surface of the first opposing surface 38 and the upper end edge 24b of the inclined surface of the second opposing surface 39 are opposed to each other in the vertical direction in the longitudinal sectional view, the lower end opening It becomes possible to suppress the backflow of the content which flowed in into the forming hole 26 from the part 26b, and can form the modeling piece Z1 precisely.

In addition, since the forming holes 26 are formed in the shape of long holes extending in the radial direction, and a plurality of the forming holes 26 are arranged at intervals in the circumferential direction, the first opposing surface 38 and the second opposing surface 39 face the circumferential direction. As shown in FIGS. 7 and 8, it is possible to form a three-dimensional object Z by combining the plurality of shaped pieces Z1 in the same direction in the circumferential direction with the shaped surface 27. It is possible to obtain a three-dimensional object Z in a twisted form.
Further, since the forming holes 26 are formed in the shape of long holes extending in the radial direction, and are arranged in plural at intervals in the circumferential direction, they mutually support the forming pieces Z1 adjacent to each other in the circumferential direction This makes it possible to form a high-precision object Z while suppressing deformation of the object Z1.

  In addition, since the inclination angles θ1 and θ2 of the inclined surfaces of the first opposing surface 38 and the second opposing surface 39 with respect to the vertical direction gradually increase from the inner side toward the outer side in the radial direction, FIGS. As shown in the figure, it is possible to form a shaped piece Z1 in which the inclination angle with respect to the vertical direction gradually increases as going from the inner side to the outer side in the radial direction. Therefore, while being able to form the modeling thing Z excellent in aesthetics, modeling piece Z1 comrades mutually adjacent in a circumferential direction can be supported mutually reliably.

Further, since the thickness of the top wall portion 24 is 0.5 mm or more and 3.0 mm or less, the top wall portion 24 can be formed with high precision while suppressing the complication of the mold structure.
If the thickness of the top wall portion 24 is less than 0.5 mm, for example, the thickness of the top wall portion 24 becomes too thin, and the lengths of the inclined surfaces of the first opposing surface 38 and the second opposing surface 39 Not only can it be ensured to such an extent that the function and effect of the invention can be achieved, the mold for molding the molding hole 26 may be too small, or the strength of the top wall 24 may be reduced.
When the thickness of the top wall portion 24 exceeds 3.0 mm, for example, there is a possibility that sinks may occur in the top wall portion 24.

  Further, since the diffusion chamber 35 is provided between the top wall portion 24 and the middle plate 16, the concentration of the contents is prevented from flowing into a specific part of the plurality of forming holes 26, The contents can be supplied with little variation in the forming holes 26. As a result, it is possible to prevent the contents from being excessively or excessively supplied to the forming holes 26 and to supply an appropriate amount of contents to each forming hole 26. Therefore, it becomes possible to form the modeling piece Z1 formed by each shaping | molding hole 26 precisely, and can form the modeling thing Z with high precision.

  Further, the content is discharged from the upper end opening 19a of the stem 19 by the operation of rotating the exterior portion 15 with respect to the container body 11 about the container axis O, and the discharge is stopped to move the inner tray 16 to the standby position. It can be restored and displaced. Thereby, for example, the operation force is reduced as compared with the case where the contents are discharged from the upper end opening 19a of the stem 19 by pushing the inner plate 16 by hand, and the contents are stabilized while the discharge amount of the contents is stabilized. The flow of the contents discharged to the modeling surface 27 while being discharged from the upper end opening 19a of the stem 19 and the discharge from the upper end opening 19a of the stem 19 are stopped and the contents in the diffusion chamber 35 are contained. It is possible to form the object Z with high accuracy by continuously making the flow of the contents discharged to the forming surface 27 while pushing it out to the forming surface 27 by the plate 16.

  Further, the receiving portion 54 for receiving the elastic force of the biasing member 21 extends radially inward from the inner cylindrical portion 22 fixed in the annular recess 18 of the top plate 17, and the guide protrusion 43 is formed on the outside. A conversion tubular portion 55 extends upward from the inner peripheral edge of the receiving portion 54. With this configuration, the rigidity of the receiving portion 54 and the outer conversion cylindrical portion 55 is enhanced, and deformation or displacement of the outer conversion cylindrical portion 55 is suppressed by the elastic force of the biasing member 21. The positional relationship with 42 can be stabilized. As a result, the above-described excellent effects of the guide projection 43 and the sliding projection 42 can be reliably achieved, and the biasing member 21 and the outer conversion cylindrical portion 55 can be used as the opening 12 a of the container main body 12. Can be compactly arranged inside the

Further, the angle formed by the first vertical surface 43a and the first inclined surface 43b of the guide projection 43 is equal to the angle formed by the second vertical surface 42a and the second inclined surface 42b of the sliding projection 42. Therefore, when the sliding protrusion 42 slides the guide protrusion 43 in the circumferential direction, the contact area between the first inclined surface 43 b and the second inclined surface 42 b can be increased. As a result, for example, when the sliding projection 42 and the guide projection 43 slide, it is possible to suppress the wear of both and stabilize the operation.
In addition, since the inclination angles with respect to the vertical direction of each of the first inclined surface 43b and the second inclined surface 42b are equal to each other, a plurality of guide protrusions 43 and sliding protrusions 42 are provided in the circumferential direction at intervals. In combination with the above, it becomes possible to suppress the inclination of the central axis of the inner plate 16 with respect to the container axis O when the exterior portion 15 is rotated, and the It can be rotated smoothly without getting caught.

Furthermore, since both the guide projection 43 and the sliding projection 42 have vertical surfaces 43a and 42a extending in the vertical direction, the rotation of the exterior 15 and the inner tray 16 with respect to the container body 11 about the container axis O Can be allowed to move in one direction only, and the sliding projection 42 that has reached the relief 55e can be moved upward quickly by the upward biasing force of the biasing member 21. Thereby, the operability when rotating the exterior portion 15 with respect to the container body 11 is improved, and the speed and the amount of the contents discharged onto the modeling surface 27 are stabilized, and the modeling accuracy of the modeling object Z is improved. It can be improved more reliably.
Also, the guide projection 43 has a curved surface 43c that protrudes downward, and the sliding protrusion 42 has a curved surface 42c that protrudes upward, so that the sliding protrusion 42 is a guide projection. You can get over 43 smoothly in the circumferential direction.
