Description

The present invention relates to a tissue paper storage container.

As a storage container for tissue paper such as wet tissues, there is a known container body in which tissue paper is alternately folded and laminated in an internal storage space, and the container body has a take-out hole for taking out the tissue paper, and a container body that protrudes from the take-out port. A so-called pop-up type is known in which when one end of the thin paper is pulled out, resistance is applied through a take-out hole and the sheets are taken out one by one (for example, see Patent Document 1).

Japanese Patent Application Publication No. 2008-168935

However, in such a tissue paper storage container, when the volume of the tissue paper stored in the storage space becomes low and the pop-up stops, the tissue paper is removed from the storage space through the ejection hole in order to make one end of the tissue paper protrude from the opening again.

Note that when the upper part of the container body rotates relative to the lower part of the container body, the direction in which the upper part of the container body faces changes, but in the following, as shown in FIG. 1, the upper part of the container body and the lower part of the container body are combined, The direction will be explained based on the state in which the storage space S is closed.

[Configuration of embodiment]
(overall structure)
As shown in FIGS. 1 to 8, the tissue paper storage container 1 includes a container body 10 having a take-out hole 113a for taking out the tissue paper P therein, and a container body 10 connected to the container body 10 so as to be openable and closable so as to cover the take-out hole 113a. A storage space S is formed inside the tissue paper storage container 1, which includes an opening/closing lid 2 and a button part 3 provided on a container body 10 and used for opening/closing the opening/closing lid 2.

(thin paper)
For example, the thin paper P is a stack of small wet sheets, wet tissues, etc. that are alternately folded and stacked, and when one wet sheet, wet tissue, etc. is pulled out, the next wet sheet, wet tissue, etc. A so-called pop-up type seat is used, which is formed so that it can be pulled out.
Note that the thin paper P may be stored in the storage space S of the thin paper storage container 1 in a state in which it is taken out from the packaging body. In this case, in order to maintain moisture easily, it is preferable to store the product in the package with the opening opened.

(container body)
As shown in FIGS. 1 to 8, the container main body 10 is, for example, formed in a generally rectangular parallelepiped shape that is longer in the Y direction than in the X and Z directions, and has a shape that extends vertically in the upper part than the central part in the Z direction. It is divided into two parts, and is formed by an upper container body 11 that constitutes the upper side of the container body 10, and a lower container body 12 that constitutes the lower side of the container body 10. The container body upper part 11 and the container body lower part 12 are connected by a connecting part 13 at the rear surface of the container body 10.
The container body upper part 11, the container body lower part 12, and the connecting part 13 are integrally formed by a method such as injection molding (two-color molding).

As shown in FIGS. 1 to 8, the container body 10 has a container body upper part 11 and a container body lower part 12 combined, and the container body 10 as a whole is preferably 60 mm in the X direction when the internal storage space S is closed. to 150 mm, more preferably 80 mm to 100 mm, preferably 80 mm to 200 mm, even more preferably 145 mm to 165 mm in the Y direction, preferably 30 mm to 100 mm, and even more preferably 50 mm to 70 mm in the Z direction. There is.
Further, the thickness of each surface is preferably 0.5 mm to 3 mm, more preferably 1 mm to 2 mm.
With this size and thickness, it is possible to achieve high molding efficiency and sufficient strength for actual use.

(Connection part)
As shown in FIG. 3, the tissue paper storage container 1 is formed to rotate about a connecting portion 13 connecting an upper container body 11 and a lower container body 12 as a fulcrum. Thereby, the storage space S can be exposed to the outside as shown in FIG. 4.
Moreover, when closing the storage space S, the user only has to rotate the container main body upper part 11 in the opposite direction.

Furthermore, as the connecting portion 13 is formed to be thinner than other parts of the tissue paper storage container 1, as shown in FIG. , it becomes easy to rotate the container main body lower part 12 using the connecting part 13 as a fulcrum.

Although productivity is reduced, it is also possible to form the container body upper part 11 and the container body lower part 12 as separate bodies, and then connect them rotatably with a hinge or the like.
Furthermore, by dividing the container body 10 into two parts above the central part in the Z direction into the container body upper part 11 and the container body lower part 12, the stored tissue paper P can be covered with a predetermined wrapping body and the storage space S When the paper is stored in a storage space S, it is possible to reduce the risk of the end seal part of the package being caught when the storage space S is closed, and it becomes easier to refill the thin paper P.
Note that the position where the container body 10 is divided into the upper container body 11 and the lower container body 12 may be near the center in the Z direction.

(Top of container body)
As shown in FIGS. 2 to 8, the container main body upper part 11 is formed, for example, in a substantially rectangular parallelepiped shape with a substantially rectangular opening on the lower surface, and a Z A concave portion 112 is formed downward in the direction, and within the concave portion 112 is provided a take-out portion 113 having a take-out hole 113a in the center for taking out the thin paper P in the storage space S. Furthermore, a housing recess 115 in which the biasing member 114 is housed is formed at the rear end, and a button attachment part 116 to which the button part 3 is attached is formed at the front end.

Furthermore, an annular outer edge 117 and an annular inner edge 118 that is provided inside the outer edge 117 and protrudes downward from the outer edge 117 are formed at the lower end of the lower surface of the upper container main body 11. A handle portion 119 is formed at the lower end of the front surface of the upper container main body 11 to be grasped when exposing the storage space S.

(Material of the upper part of the container body)
The container main body upper part 11 is formed of a hard material. As the hard material, for example, hard plastics such as polyethylene (PE), polypropylene (PP), polyoxymethylene (POM), ABS resin, etc. can be used.
Further, it is desirable that a portion formed of an elastic material and a portion formed of a hard material, which will be described later, be integrally molded by injection molding (two-color molding).

(concavity)
As shown in FIG. 2, the recessed portion 112 is formed near the center of the top surface portion 111 in a plan view. Although FIG. 2 shows a case where the recess 112 has a substantially rectangular curved shape that reaches the front end of the upper container main body 11 in plan view, the specific shape of the recess 112 is not limited to this.
The depth of the recessed portion 112 in the Z direction is preferably 5 mm to 20 mm when viewed from the top surface portion 111. Further, the size in plan view is not particularly limited as long as the take-out portion 113 can be formed inside, but it is preferably 40 mm to 80 mm in the X direction and 40 mm to 120 mm in the Y direction.

(Ejecting part)
The take-out part 113 is a part formed near the center of the recess 112 in a plan view and is made of an elastic material, and is formed in the shape of a film with a thickness of 0.5 mm to 2 mm in the Z direction, for example. Desirably, a substantially spherical bulging portion 113b is formed approximately at the center of the extraction portion 113, and an extraction hole 113a is provided in the bulging portion 113b.
Moreover, three projecting pieces 113c are provided on the edge of the extraction hole 113a, protruding from the edge on the near side toward the center of the extraction part 113.

(Material of extraction part)
As the elastic material forming the extraction part 113, for example, an elastic material such as silicone rubber or a thermoplastic elastomer such as styrene-butadiene, polyester, polyethylene, or urethane can be used, and the hardness is from 20 to 20. 90 is desirable. Note that the above hardness was measured according to JIS K 6253 (Type A durometer).

Note that if the hardness of the elastic material is lower than the above value, it is undesirable because it is too soft and difficult to mold, resulting in poor molding efficiency.
Further, if the hardness of the elastic material is higher than the above value, the take-out part 113 in which the take-out hole 113a for taking out the thin paper P is formed becomes hard, and too much resistance is applied, making it difficult to take out the sheets one by one. Alternatively, this is not desirable because it becomes difficult to insert one's fingers into the storage space S when pulling out the sheet.

(Ejection hole)
The take-out hole 113a is a hole connected to the storage space S, which is formed in the center of the take-out part 113 in a plan view.
For example, in FIG. 2, the extraction hole 113a has a triangular shape in which each side protrudes inward in an arc shape, and three slits intersect at the center of gravity so as to connect each vertex and the center of gravity. It is shaped like a letter. Further, among the three slits, the width of the slit extending in the X direction is wider than the width of the other slits.
Note that the number of slits may be smaller or larger than this, and for example, two slits may be formed in a cross shape.

The extraction portion 113 has an elastic material surrounding the extraction hole 113a, so that appropriate resistance is applied to the thin paper P, and after the thin paper P stored in the storage space S is pulled out, It functions to hold one end of the next thin paper P. Further, when the thin paper P is a rolled sheet, it is possible to cut the thin paper P using a cutting perforation provided in the thin paper P.

(projection)
The protruding piece 113c is a place where the thin paper P pulled out from the take-out hole 113a comes into sliding contact, and is provided so as to apply appropriate resistance to the thin paper P pulled out from the take-out hole 113a.

Specifically, when the user opens the opening/closing lid 2 of the tissue paper storage container 1 to take out the tissue paper P, the opening/closing lid 2 in an upright position on the back side of the tissue paper storage container 1 obstructs the operation to take out the tissue paper P. To prevent this from happening, the user extends his hand from the front side of the tissue paper storage container 1 and pulls out the tissue paper P from the ejection hole 113a, so that the tissue paper P pulled out from the ejection hole 113a is pulled out from the protrusion 113c on the edge of the front side. It comes into sliding contact with.

At this time, the protruding piece 113c protruding backward from the edge on the near side comes into sliding contact with the thin paper P pulled out to the front side from the ejection hole 113a, so that the protruding piece 113c provides appropriate resistance to the thin paper P. This prevents the thin paper P from being pulled out too much from the ejection hole 113a.

In other words, the protruding piece 113c protruding backward from the front edge applies an appropriate frictional force to the thin paper P pulled out to the front side from the extraction hole 113a, and the protrusion 113c applies an appropriate frictional force to the thin paper P pulled out and used. It has a function to prevent the next thin paper P to be pulled out from the take-out hole 113a.
Then, the next thin paper P pulled out following the thin paper P to be used is held in the take-out hole 113a with one end thereof pulled out to an appropriate length.

Further, one end portion of the thin paper P held in the ejection hole 113a in this manner is supported by three protrusions including the protrusion 113c on the near side.
Since the take-out hole 113a that holds one end of the thin paper P is provided in the bulging portion 113b of the take-out portion 113, the tip side of each protrusion 113c is connected to the take-out portion 113, which is the base surface around the bulge portion 113b. located higher than.
One end of the thin paper P is supported by such a protrusion 113c at a higher position than the surrounding area and held in the take-out hole 113a, making it easier to pick up the thin paper P.

(biasing member)
As shown in FIG. 2, the biasing member 114 is a band-shaped member made of an elastic material. One end of the biasing member 114 is fixed to the rear of the recess 112, and the other end is fixed to the insertion part 23 (described later) of the opening/closing lid 2, and urges the opening/closing lid 2 in the opening direction to stand up. When the user presses the button part 3, the opening/closing lid 2 is opened by rotating the connection part with the rear container main body upper part 11 as a rotation axis.

The biasing member 114 is formed into a band shape with a width of preferably 2 mm to 30 mm, more preferably 8 mm to 10 mm, and a thickness of preferably 0.5 mm to 3 mm, and even more preferably 1 mm to 2 mm.
By forming the biasing member 114 to such a size, it is possible to push it up without force when the opening/closing lid 2 is opened, and when the opening/closing lid 2 is closed, the biasing member can be pushed up into the storage recess 115. It can be easily folded and stored inside.

By forming the biasing member 114 so that it is in an extended state as shown in FIG. 2 when no force is applied, the opening/closing lid 2 is closed as shown in FIG. 7, and the biasing member 114 When it is bent, a force is generated to return it to the state shown in FIG. This makes it possible to urge the opening/closing lid 2 to rotate rearward with respect to the container main body upper part 11 using the connecting portion 13 between the rear opening/closing lid 2 and the container main body upper part 11 as the rotation axis. .

(Storage recess)
As shown in FIG. 7, the storage recess 115 is a recess for storing the bent portion of the biasing member 114 when the biasing member 114 is pushed downward when the opening/closing lid 2 is closed. .
As shown in FIG. 2, the storage recess 115 is formed so as to be concave further downward in the Z direction than the recess 112 at the rear of the take-out portion 113 in the recess 112 and near the front of the biasing member 114.
The shape of the storage recess 115 is not particularly limited, but, for example, it has a substantially rectangular parallelepiped shape that is longer in the Y direction than in the X direction. It is sufficient if the space is large enough to accommodate the member 114.

(Button mounting part)
The button attachment part 116 is formed of a hard material at the front end of the recess 112 and has a main body side fitting part 1161 formed in an annular shape convex upward in the Z direction in a plan view. The button movable part 1162 is formed to be concave downward in the Z direction so as to surround the left and right parts and the front part of the part 1161.

(Main body side fitting part)
The main body side fitting portion 1161 has, for example, a curved front side and a straight line shape on the rear side in a plan view, and has an inner periphery slightly larger than an outer periphery of a button side fitting portion 32 (described later) formed in the button portion 3. It is formed. The button part 3 can be attached to the button attachment part 116 by inserting the button side fitting part 32 from above.

(Button movable part)
The button movable part 1162 is formed to be concave downward so as to surround the left and right parts and the front part of the main body side fitting part 1161, and is made of the same elastic material as the take-out part 113. Thereby, when the tip end 31a of the button part inserted into the main body side fitting part 1161 is pressed from above, the button movable part 1162 is elastically deformed, so that the button part 3 is formed to tilt downward. .

(outer edge/inner edge)
The outer edge portion 117 is annular as shown in FIGS. 4 and 5, and is formed at the lower end of the upper portion 11 of the container body.
The inner edge part 118 is annular as shown in FIGS. 4 and 5, is provided inside the outer edge part 117 at the lower end of the container main body upper part 11, protrudes below the outer edge part 117, and prevents the storage space S from being blocked. Sometimes, the inner edge 118 is formed so as to fit into a groove 121 of the lower part 12 of the container main body, which will be described later.

(Handle part)
For example, as shown in FIGS. 1 to 8, the handle portion 119 is formed integrally with the container body upper portion 11 at the center of the front surface of the container body upper portion 11 so as to protrude in an arch shape from the front surface. A gap a is formed between the cover and the front surface in which a finger can be caught. Two locking parts 1191 are provided on the inner surface facing the front surface of the handle part 119. When exposing the storage space S, the handle portion 119 is grasped and the container main body upper portion 11 is rotated using the connecting portion 13 as a fulcrum.

Further, as shown in FIGS. 7 and 8, the portion where the front surface of the container body upper part 11 and the inner surface of the handle portion 119 intersect is R-shaped and is formed to be rounded. .
Note that the shape of the handle portion 119 does not have to be an arch-shaped shape, but may be any shape as long as it projects from the front surface of the container body upper portion 11 and has a gap a between it and the front surface. good.

In addition, the handle portion 119 overlaps an engagement protrusion 123 (described later) provided on the lower container body portion 12 in the front-rear direction when the upper container body portion 11 and the lower container body portion 12 are engaged. This provides a structure in which the engaging protrusion 123 is not visible from the front.

(locking part)
As shown in FIGS. 4 to 8, two locking portions 1191 are provided on the inner surface of the handle portion 119 at a predetermined interval along the left-right direction, and when the storage space S is closed, the locking portions 1191 engage the engaging projections. 123 to maintain the closed state.
The distance between the two locking portions 1191 is arbitrary, but preferably larger than the finger width of a typical user. Specifically, it is preferable that they are formed at a distance of 5 mm to 25 mm, more preferably 18 mm to 25 mm.
Note that the number of locking portions 1191 is not limited to two, and may be provided at positions spaced from the left and right portions of the inner surface of the handle portion 119, for example, two on each side ( (4 in total) may be provided.

(Bottom part of container body)
As shown in FIG. 4, the lower container main body 12 is formed into a substantially rectangular parallelepiped shape with a substantially rectangular opening on the upper surface, and an annular groove 121 is formed at the upper end.
In addition, at the bottom of the upper surface of the lower part 12 of the container main body, when the thin paper P is stored in the storage space S without using an elastic member 125, which will be described later, a slippery surface is provided to prevent slipping when the thin paper P is taken out from the take-out hole 113a. A stop portion 122 is formed.
Further, near the center of the upper end of the front surface of the lower container main body 12, an engagement protrusion 123 that projects forward is formed integrally with the lower container main body 12.
Furthermore, a plurality of support parts 124 that support elastic members 125 are formed on the inner surface of the side surface of the lower part 12 of the container body.

(Material of the lower part of the container body)
The lower container body 12 is made of the same hard material used in the upper container body 11.

(concave groove)
The groove portion 121 is annular as shown in FIG. 4, and is formed at the upper end of the lower container body 12 so that the inner edge 118 of the upper container body 11 engages when closing the storage space S. The cage includes an outer circumferential wall portion 1211 and an inner circumferential wall portion 1212.

(Outer wall/inner wall)
The outer circumferential wall portion 1211 is formed as an outer circumferential wall surface of the lower container body portion 12, and comes into contact with the outer edge portion 117 of the upper container body portion 11 when closing the storage space S.
The inner circumferential wall portion 1212 is formed as an inner circumferential wall surface of the lower part 12 of the container body, projects upwardly from the outer circumferential wall portion 1211, and, as shown in FIG. 1212a, and a plurality of second guide portions 1212b provided in the left-right direction on the rear surface.
The inner edge 118 of the upper container main body 11 comes into sliding contact between the outer circumferential wall 1211 and the inner circumferential wall 1212, thereby maintaining the airtightness of the storage space S.

(1st and 2nd guide part)
The first guide portion 1212a is provided, for example, at both left and right ends of the rear surface of the lower container main body 12, extending to the left or right surface, respectively, and has a height in the Z direction that is higher than the outer circumferential wall portion 1211 and the second guide portion 1212b. expensive.
The second guide portions 1212b are wave-shaped, and are provided in plural along the left-right direction on the rear surface of the lower container main body 12, and have a height higher in the Z direction than the outer peripheral wall portion 1211, but lower than the first guide portion 1212a. .

(Non-slip part)
The anti-slip part 122 is formed of an elastic material surrounded by a hard material at the bottom of the lower part 12 of the container body, and is formed by, for example, two straight lines connecting opposite vertices of a rectangle as shown in FIG. intersect at the center of gravity, and the two straight lines extend in the Y direction, forming an arc.
Furthermore, the four ends of the two straight lines are circular, and as shown in FIG. fulfill the role of

(Engaging protrusion)
As shown in FIGS. 4 and 5, the engaging protrusion 123 is a protrusion that protrudes forward, integrally with the lower container body 12, at approximately the center of the upper end of the front surface of the lower container body 12. When the space S is closed, the two locking portions 1191 are engaged.
The engagement protrusion 123 is formed so that its length in the Y direction is longer than the sum of the interval between the two locking portions 1191 and the length of each of the two locking portions 1191 in the Y direction.

(Support part)
For example, as shown in FIGS. 4, 5, 7, and 8, the support portion 124 is formed so that it protrudes toward the opposite side surface of the lower container body 12 and has a tip that protrudes upward in the Z direction. It is a substantially L-shaped member formed when viewed from the side. For example, as shown in FIG. 4, two support portions 124 are formed on each of the short side portions and three support portions are formed on each of the long side portions among the four side portions of the lower container main body 12.

The support portion 124 may be formed to be capable of locking the elastic member 125 that supports the thin paper P in the lower part 12 of the container body. Furthermore, in consideration of the stability of support of the thin paper P by the elastic member 125, at least a portion of the support portion 124 is provided at a position where the elastic member 125 faces the lower part 12 of the container body across the approximate center of the bottom surface. However, the number of supporting parts 124 and their positions are arbitrary depending on the size of the container main body 10 and the thin paper P to be stored.

(Material of support part)
The support portion 124 can be made of any material, but considering that the wet sheet can be stored in the storage space S, it is preferably made of a rust-proof hard material.
In addition, in the manufacturing process of the tissue paper storage container 1, it is possible to manufacture only the support part 124 separately and attach it to the lower part 12 of the container body, but considering manufacturing efficiency and strength, etc. Preferably, it is formed in one piece from a hard material.

(elastic member)
As shown in FIGS. 4, 5, 7, and 8, the elastic member 125 is a string-like elastic member that is stretchable, and has an annular shape, for example, like a rubber band. 1124 constitutes a supported part.
The supported part may have any shape as long as it is supported by the support part 124, and may have any configuration, such as having only a circular end.
By removably locking the elastic member to at least two supporting parts 124, the elastic member is stretched so as to be stretched substantially parallel to the bottom surface of the lower part 12 of the container main body.

(Material of elastic member)
The elastic member 125 is highly stretchable, moisture resistant, has a length sufficient to stretch the container body 10 in the Y direction, and has an elongation of 200 to 500%. For example, it is made of natural rubber. , silicone rubber, styrene-butadiene rubber, chloroprene rubber, etc. can be used as raw materials.

Note that the elongation here refers to the elongation when the elastic member 125 is stretched in the length direction using a tensile tester (TENSILON RTG-1210 by AND) set at a distance between chucks of 50 mm and a speed of 300 mm/min. When the distance between the chucks is L, it can be calculated as (L/50)×100(%), and represents the maximum amount of expansion of the elastic member 125.
For example, if the distance between the chucks at breakage is 200 mm, the elongation is (200/50)×100, which is 400%.

The button part 3 includes an upper surface part 31 forming an upper surface, a button side fitting part 32 that projects downward from the upper surface part 31, and a button side locking part 33 that engages the opening/closing lid side locking part 21. By inserting the opening/closing lid side locking part 21 into the button side locking part 33, the opening/closing lid 2 is locked in the closed state, and when the user presses the button part 3, the opening/closing lid 2 is locked. The lid-side locking portion 21 is disengaged and the opening/closing lid 2 is opened.
The button part 3 is formed independently as a separate member from a hard material similar to that used in the container body 10, and is then fixed by a button attachment part 116.
It is preferable that the tissue paper storage container 1 is entirely integrally formed by injection molding (two-color molding), except for the opening/closing lid 2 and the button part 3, as described above.

(Top part)
As shown in FIGS. 1, 7, and 8, the upper surface portion 31 is a portion that forms the upper surface of the button portion 3. For example, in a plan view, the rear side is linear, the front side is arcuate, and the area near the tip 31a is The tip 31a is formed to have substantially the same shape in plan view as the vicinity of the front end of the recess 112 except for the front end thereof, and the tip 31a is formed to protrude forward from the recess 112.
The size of the upper surface part 31 is determined according to the size of the part of the recess 112 that is not covered by the opening/closing lid 2, and is 10 mm to 30 mm at the longest part in the X direction and 30 mm to 30 mm at the longest part in the Y direction. Preferably, it has a length of 100 mm.

A gap b is formed between the tip 31a of the top surface part 31 and the container body upper part 11, and the tip part 31a and the base end 31b are formed at different angles with respect to the upper surface (horizontal) of the container body upper part 11. It is formed to slope downward.
At this time, the inclination angle of the distal end portion 31a is formed to be larger than the inclination angle of the proximal end portion 31b. Specifically, it is preferable that the inclination angle of the proximal end portion 31b is 6 to 8 degrees, and the inclination angle of the distal end portion 31a is 8 to 10 degrees.
In addition, the base end 31b of the button part may be parallel to the container main body upper part 11 and only the tip 31a may be inclined downward, or it may be inclined at the same angle from the base end 31b to the tip 31a. good.

(Button side fitting part)
The button side fitting part 32 protrudes downward from the upper surface part 31 in an annular shape, for example, having a curved front side and a straight line shape in the rear side when viewed from the bottom, and the outer periphery is longer than the inner periphery of the above-mentioned main body side fitting part 1161. The button part 3 is formed to be slightly small and can be attached to the button attachment part 116 by inserting it into the main body side fitting part 1161 from above.
The inner periphery is formed to be the same as or slightly larger than the outer periphery of the above-mentioned main body side fitting part 1161, and the button part 3 can be attached to the button mounting part 116 by inserting the main body side fitting part 1161 from below. It may be formed so that it can be done.

(Button side locking part)
The button side locking part 33 is a hole formed at the rear of the button part 3, and when the opening/closing lid side locking part 21 formed on the opening/closing lid 2 is inserted and engaged, the opening/closing lid 2 is locked in the closed state, and when the user presses the button part 3, the opening/closing lid side locking part 21 is uninserted, and the opening/closing lid 2 is opened by the urging force generated by the urging member 114. It is formed to be in a state.

[Effects of embodiment]
The main effects obtained by this embodiment will be explained below.

(Support part/elastic member)
A support part 124 is provided on the lower part 12 of the container body, an elastic member 125 is locked to the support part 124, and the elastic member 125 is stretched approximately parallel to the bottom surface of the lower part 12 of the container body, so that the thin paper in which the elastic member 125 is housed is formed. It becomes possible to support P along with the package.

As shown in FIG. 7, when closing the storage space S, the elastic member 125 is pressed downward in the Z direction by the container main body upper part 11 and the thin paper P, and the supporting part of the thin paper P is pushed downward in the Z direction. It will bend.

Therefore, even if the thin paper P is used and its bulk and weight are reduced, the elastic force of the elastic member 125 lifts the thin paper P upward in the Z direction, as shown in FIG. Even if one end sinks into the storage space S from the removal hole 113a, there is no need to put one's finger deep into the storage space S, making it easy to take it out again. Further, even when the volume of the thin paper P decreases, an appropriate distance between the take-out hole 113a and the thin paper P in the storage space S is maintained, and the take-out performance is maintained.

(overall structure)
Furthermore, since the container body 10 is composed of an upper container body 11 and a lower container body 12, and these are connected by a connecting part 13 on the rear surface, the tissue paper storage container 1 can be placed on the placement surface. By rotating the container main body upper part 11 about the rear end part as a fulcrum, the storage space S is exposed and the thin paper P can be refilled.
Therefore, when refilling the thin paper P, the refilling operation can be performed more easily while the thin paper P remains placed on the placement surface.

(Button part, etc.)
In the tissue paper storage container 1, the button part 3 is provided, and since the inclination angle of the tip part 31a is larger than the inclination angle of the base end part 31b, the gap between the button part 3 and the upper part 11 of the container main body is It becomes difficult to put a finger in b, and when refilling the thin paper P, it is possible to prevent the user from grasping the button part 3 mistakenly for the handle part 119 and trying to turn it.

Moreover, since the button part 3 is attached to the main body side fitting part 1161 surrounded by the button movable part 1162 that protrudes downward, the upper surface of the button part 3 When the user presses the button 31 from above, the button movable part 1162 is distorted downward, regardless of the position of the press, causing the button part 3 to sink downward.

At this time, since the opening/closing lid side locking part 21 of the opening/closing lid 2 is inserted into the button side locking part 33 of the button part 3, when the button part 3 sinks downward, the opening/closing lid 2 also moves accordingly. Although the opening/closing lid 2 is pushed downward, the opening/closing lid 2 is urged upward by the urging member 114, and such urging force becomes stronger as the opening/closing lid 2 sinks downward.

Therefore, when the button part 3 is pushed in to a certain extent, the opening/closing lid 2 sinks in response, and the upward biasing force on the opening/closing lid 2 becomes stronger, but the opening/closing lid 2 and the button part 3 are Since they are engaged only by the locking part 21 and the button-side locking part 33, when the urging force on the opening/closing lid 2 becomes strong, this engagement is released and the opening/closing lid 2 is opened.

Therefore, according to the present embodiment, the opening/closing lid 2 can be easily opened no matter which part of the upper surface of the button part 3 is pressed.

Moreover, since the container main body upper part 11 has the button attachment part 116 having the main body side fitting part 1161, the button part 3 can be easily and stably fixed.

(Handle part)
A handle part 119 is provided in the upper part 11 of the container body, and the inner circumferential side of the handle part 119 is formed into a curved surface by R processing, so that the handle part 119 can be easily expanded outward compared to a case where the inner circumferential side is an acute angle. Therefore, it becomes easy to disengage the locking portion 1191 and the engagement protrusion 123, and the storage space S can be easily exposed.

Further, the handle portion 119 overlaps an engagement protrusion 123 provided on the lower container body portion 12 in the front-rear direction when the upper container body portion 11 and the lower container body portion 12 are engaged. As a result, the engaging protrusion 123 is not visible from the front, which is good for appearance.

Further, since the handle part 119 is provided with a locking part 1191, the user can hook the finger into the gap a between the front surface of the container body upper part 11 and the handle part 119, and hold the container body upper part 11 and the container body lower part 11. The storage space S can be exposed by easily releasing the engagement.

In particular, since a plurality of locking portions 1191 are provided at positions left and right away from the center in the left-right direction on the inner surface of the handle portion 119, when a finger is inserted near the center of the handle portion 119, the locking portions 1191 does not get in the way, and the storage space S can be exposed by releasing the engagement between the container body upper part 11 and the container body lower part 12 more easily.

Further, two locking portions 1191 are formed on the inner surface of the handle portion 119, and the interval between the two locking portions 1191 is wider than a finger width, so that the container main body upper portion 11 can be rotated. At this time, it becomes easier for a finger to enter between the two locking parts 1191, and it becomes easier to rotate the container main body upper part 11, so that the storage space S can be easily exposed.

Further, the length of the engagement projection 123 in the left-right direction is longer than the sum of the length of the two locking portions 1191 in the left-right direction and the distance between the two locking portions 1191. Since the two locking portions 1191 are engaged, the strength is increased compared to providing the locking protrusion 123 individually for each locking portion 1191, and the locking portions 1191 can be engaged more stably. .

Furthermore, since the container body upper part 11, the container body lower part 12, and the connecting part 13 are integrally formed by a method such as injection molding (two-color molding), the manufacturing efficiency of the tissue paper storage container 1 is also excellent. .

(Ejection hole)
The next thin paper P pulled out from the take-out hole 113a is held in the take-out hole 113a with one end pulled out to an appropriate length, so that the thin paper P held in the take-out hole 113a is removed from the opening/closing lid 2. It won't get in the way when you close it.

In addition, since the tissue paper P held in the ejection hole 113a will not be caught between the opening and closing lid 2, the moist tissue paper P (wet tissue, etc.) will not be caught between the opening and closing lid 2 and protrude outside the container body 10. There are no problems such as dryness.

If the tissue paper storage container 1 is provided with the ejection hole 113a, the tissue paper P can be suitably drawn out and used, and one end of the next tissue paper P that is drawn out after the tissue paper P that has been drawn out and used is The opening/closing lid 2 can be held in the extraction hole 113a so as not to interfere with closing the lid.
The thin paper P that has been pulled out to an appropriate length is held in the take-out hole 113a, so that the thin paper P stored in the storage space S can be repeatedly pulled out and used. I can do it.

In addition, among the three slits of the extraction hole 113a, only the width of the slit extending in the The support points for one end of the thin paper P held in the hole 113a are now dispersed, and the one end of the thin paper P can be more stably supported by the take-out hole 113a.

Further, since the widths of the other two slits extending toward the front side are relatively narrow, it is possible to prevent one end portion from entering the slit when taking out the thin paper P.

(biasing member)
Further, according to the tissue paper storage container 1 according to the present embodiment, the opening/closing lid 2 can be urged in the opening direction simply by providing the urging member 114 made of an elastic material on the upper part 11 of the container main body.

On the other hand, if, for example, a spring-like biasing member that stands upwardly is provided and is connected to the opening/closing lid 2, this may repeatedly break or stretch each time the opening/closing lid 2 is opened or closed. Therefore, such a spring-like portion tends to deteriorate, and the biasing force against the opening/closing lid 2 tends to weaken early. If the urging force on the opening/closing lid 2 weakens to a certain extent, it will no longer be possible to release it with a single touch.

According to the present embodiment, the biasing member 114 formed of an elastic material is pushed by the opening/closing lid 2 to generate a biasing force on the opening/closing lid 2, so that the portion made of the elastic material is deformed. Since the amount is small and it is difficult to deteriorate, the urging force on the opening/closing lid 2 is difficult to weaken.

Further, by providing the storage recess 115 in the recess 112, it is possible to prevent the pressure applied to the contact portion of the biasing member 114 with the recess 112 from becoming too large, and it is possible to reduce the risk of the biasing member 114 being damaged. .

Furthermore, since the biasing member 114 is formed on the rear side of the container body 10, close to the fulcrum of rotation of the lid 2, the biasing force against the lid 2 is strengthened, making it easier to open the lid 2.

(Other configurations)
Furthermore, since the anti-slip portion 122 is provided on the upper surface of the lower part 12 of the container body, when the thin paper P is stored in the storage space S without using the elastic member 125, when the thin paper P is taken out from the take-out hole 113a. Since the thin paper P in the storage space S moves and becomes less likely to collapse, the thin paper P can be taken out stably.

In addition, a portion forming the anti-slip portion 122 comes into contact with the placement surface and serves as the placement portion 1221, thereby increasing the stability when the tissue paper storage container 1 is placed on the placement surface. can.

Further, when the open/close lid 2 is closed, the open/close lid side sealing ring portion 22 is in contact with the outer periphery of the take-out portion 113, so that the airtightness of the storage space S can be improved.

[Modified example]
Modifications of the above embodiment will be described below.

(Method of locking elastic member)
Since the elastic member 125 can be removably locked to the support portion 124, the elastic member 125 is not limited to being locked so as to be stretched in the X direction (lateral direction), as shown in FIG. In order to adjust the elastic strength of the elastic member 125 according to the bulk and weight of the elastic member 125, it is possible to arbitrarily change the supporting portion 124 to be locked.

For example, as shown in FIG. 9(a), by locking the lower part 12 of the container main body so as to stretch it in the Y direction (longitudinal direction), the elastic member 125 can have a large elastic strength, and the thin paper P can It becomes difficult to bend downward when supported. Therefore, even when the volume of the thin paper P is low, it becomes easy to lift upward in the Z direction, and it becomes easy to maintain an appropriate distance between the take-out hole 113a and the thin paper P and the take-out performance of the take-out hole 113a. Further, even if the pop-up of the thin paper P from the take-out hole 113a is interrupted, it becomes easy to insert a finger deep into the storage space S from the take-out hole 113a and take it out again.
In particular, as shown in FIG. 9(b), by increasing the number of supports 124 that lock the elastic member 125, the elastic strength of the elastic member 125 can be further increased.

On the other hand, as shown in FIG. 4, for example, by locking the lower part 12 of the container body in a stretched manner in the X direction (lateral direction), the elastic strength of the elastic member 125 can be reduced. When supporting the thin paper P, it bends downward. Therefore, when the thin paper P is heavy or bulky, the load applied to the support portion 124 and the elastic member 125 can be reduced, and more thin paper P can be stored. Become.
In particular, as shown in FIG. 9(c), by reducing the number of supports 124 that lock the elastic member 125, the elastic strength of the elastic member 125 can be further reduced.

Note that the method of locking the elastic member 125 is not limited to the above-mentioned form, and any method can be adopted depending on the purpose, but the method is such that the elastic member 125 can stably support the thin paper P. Taking this into consideration, it is preferable that at least the elastic member 125 is anchored so as to stretch over the substantially central portion of the bottom surface of the lower container main body 12.

Note that, as described above, the elastic member 125 changes the locking method depending on the thin paper P, so it is preferable that the elastic member 125 is detachable. However, the elastic member 125 is not limited to this. I don't mind.

(Support part)
As shown in FIG. 4, instead of separately forming the support part 124 on the side surface of the lower container main body 12, as shown in FIG. Alternatively, the second guide portion 1212b may be provided on the other three side portions, and the second guide portion 1212b may be used as the support portion 124b.

By doing so, the manufacturing process can be further simplified. Furthermore, since the support portions 124b do not protrude to the opposing side surfaces, the storage space S can be used more efficiently.
Note that even when the second guide portion 1212b is used as the support portion 124b, the inner edge portion 118 of the container body upper portion 11 is in sliding contact between the outer circumferential wall portion 1211 and the inner circumferential wall portion 1212, so that the airtightness of the storage space S is maintained. be done. Further, at this time, the elastic member 125 comes into contact with the inner edge portion 118 and serves as a cushioning material.

(elastic member)
The elastic member 125 has an annular shape, and although the entire structure is described as a supported portion, the present invention is not limited to this, and supported portions may be provided at both ends.
The configuration in which supported parts are provided at both ends may be arbitrary, such as a method of attaching hooks or the like to both ends of the string-like elastic member 125, such as a rubber band, or a method of perforating or providing a cut at both ends. It is possible to take the following configuration.

(Handle part)
The handle portion 119 may be integrally molded with other parts of the container upper portion 11, or may be constructed separately and attached later.
(Engaging protrusion)
The number of engagement projections 123 is not necessarily one, and two engagement projections 123 may be provided for each of the two locking portions 1191.
(Guide part)
The guide portion may include only the first guide portion 1212a or may include only the second guide portion 1212b.
The first guide portion 1212a does not necessarily have to be provided extending to the left or right surface.
The second guide portion 1212b does not have to be wavy and may be provided at the same height in the left-right direction.
(Button part)
The button part 3 only needs to be provided on the container main body upper part 11 so as to be movable up and down by the button movable part 1162, and does not necessarily need to be attached by the button attachment part 116. For example, the button movable portion 1162A may be made of an elastic material, provided over the entire lower side of the button portion 3, and then the button portion 3 may be attached directly onto the button movable portion 1162A by a method such as adhesive.

(Connection part)
In the above description, a case has been described in which the connecting portion 13 is formed only at one location near the center in the left-right direction of the thin paper storage container 1, but the configuration of the connecting portion 13 is not limited to this.
For example, the connecting portions 13A, 13A may be formed on the left and right sides of the tissue paper storage container 1A. In this case, when the storage space SA is exposed, the connecting portion 13A becomes difficult to twist, improving its stability and making it easier to close it again.

Alternatively, a connecting portion 13B may be used that covers the entire rear surface of the tissue paper storage container 1B. In this case, when the storage space S is closed, the entire rear side of the contact area between the upper container body 11 and the lower container body 12 of the tissue paper storage container 1B is covered, so that the airtightness of the storage space S is further improved. can be increased.

In addition, the detailed structure of the tissue paper storage container 1 can be changed as appropriate without departing from the gist of the present invention.
