[ Structure of embodiment ]
{ Overall Structure }
As shown in fig. 1 to 4, the home tissue paper storage container 100 includes, for example: a container body 1 having a taking-out hole 112a for taking out household tissue inside; an opening/closing lid 2 openably and closably connected to the container body 1 so as to cover the removal hole 112 a; and a biasing means 3 for biasing the opening/closing lid 2 in an opening direction, and a housing space S for housing the household tissue paper P is formed inside the container body 1.
The container body 1 and the opening/closing lid 2 can be integrally formed by injection molding (two-color molding).
{ household tissue paper }
As the household tissue paper P, for example, a so-called pop-up sheet is used, which is formed by stacking small wet sheets, wet tissues, and the like in an alternately folded state, and pulling out a next wet sheet, wet tissue, and the like when pulling out one wet sheet, wet tissue, and the like. For example, a long wet sheet or wet tissue having a perforation line applied thereto at regular intervals in the longitudinal direction may be wound into a roll and cut off along the perforation line.
{ container body }
As shown in fig. 1, the container body 1 is formed in a substantially rectangular parallelepiped shape longer in the Y direction than in the X direction and the Z direction as a whole, and the container body 1 is divided into two upper and lower portions in the vicinity of a substantially central portion in the Z direction, and a container body upper portion 11 constituting an upper side of the container body 1 and a container body lower portion 12 constituting a lower side of the container body 1 are formed. The upper container body part 11 and the lower container body part 12 are connected at the rear side of the container body 1.
The container body upper part 11 and the container body lower part 12 can be integrally formed by injection molding (two-color molding).
The container body 1 is preferably formed to have a size of 60mm to 150mm, more preferably 80mm to 100mm, in the X direction, preferably 80mm to 200mm, more preferably 145mm to 165mm, in the Y direction, and preferably 30mm to 100mm, more preferably 50mm to 70mm, in the Z direction. The thickness of each surface is preferably 0.5mm to 3mm, more preferably 1mm to 2 mm.
If the size and thickness are the same, the molding efficiency is high and the strength without problems in practical use can be realized.
As shown in fig. 4, the container body 1 can open the internal storage space S to the outside by rotating the container body upper portion 11 upward about the rear side where the container body upper portion 11 and the container body lower portion 12 are connected as a fulcrum.
As shown in fig. 2 to 4, the connecting portion between the container body upper portion 11 and the container body lower portion 12 on the rear side of the container body 1 is formed to be thinner than the other portions of the container body 1, so that the rear surface of the container body can be easily bent at the connecting portion, and the container body upper portion 11 can be easily rotated with respect to the container body lower portion 12 with the connecting portion as a fulcrum.
Further, although productivity is lowered, the container body upper part 11 and the container body lower part 12 are formed separately, and as a result, they can be rotatably connected by a hinge or the like.
The container body 1 is divided into two parts, i.e., the container body upper part 11 and the container body lower part 12, and the position is shown in the figure as being near the center part in the Z direction. In this case, when the stored household tissue paper P is stored in the container body 1 in a state where the stored household tissue paper P is covered with a predetermined package, the possibility of pinching the end seal portion of the package or the like when the container is closed can be reduced, and replacement of the household tissue paper P can be facilitated.

The biasing means 3 biases the opening/closing lid 2 in the opening direction, and when the user presses the locking means 114 and releases the engagement between the body-side claw portions 1141 and the opening/closing lid-side claw portions 21, the opening/closing lid 2 is rotated about a rear connecting portion with the container body upper portion 11 as a rotation axis to be opened.
The urging unit 3 is a plate spring-like member formed of a thermosetting resin material such as elastic silicone resin (silicone rubber).
As shown in fig. 5A, the biasing unit 3 has a small hole 3a at one end, and a fixing portion 115 is inserted into the small hole 3 a.
Specifically, when the opening/closing lid 2 and the container body 1 are integrally formed by injection molding (two-color molding), the elastic material serving as the fixing portion 115 is injected so as to be inserted into the small hole 3a of the biasing unit 3 formed in advance of a thermosetting resin material, and the biasing unit 3 is formed so as to be fixed to the molded fixing portion 115 and to be embedded in the recess 111.
That is, the biasing unit 3 is fixed to the fixing portion 115 in a state where the fixing portion 115 is partially formed by injection molding. In other words, the manufacturing process of the household tissue paper storage container 100 includes a process of fixing the biasing unit 3 formed in advance of the thermosetting resin material to the fixing portion 115 when the fixing portion 115 is injection-molded from an elastic material.
Further, in a state where the fixing portion 115 is formed in a part of the container body 1 formed by injection molding, the biasing unit 3 fixed to the fixing portion 115 is fixed in a state where it cannot be removed from the container body 1 (the fixing portion 115).
In this way, the container body 1, the opening/closing lid 2, and the biasing means 3 can be formed by pseudo three-color molding, and the home tissue paper container 100 can be produced.
If the urging unit 3 is fixed to the fixing portion 115 formed by injection molding, the household tissue paper storage container 100 can be manufactured with good productivity.
As shown in fig. 5B, even in the case of the biasing unit 3 having the notch 3B at one end portion thereof, the biasing unit 3 can be similarly fixed to the fixing portion 115 of the injection molding.
The urging unit 3 is formed in a belt shape having a width of preferably 5mm to 30mm, more preferably 8mm to 15mm, and a thickness of preferably 0.5mm to 3mm, more preferably 1mm to 2 mm.
The biasing unit 3 is formed in such a size that the opening/closing cover 2 can be easily pushed up and the biasing unit 3 can be easily bent in the concave portion 111 when the opening/closing cover 2 is closed.
As shown in fig. 3, when the opening/closing cover 2 is closed, the urging unit 3 is bent in the vicinity of the root of the opening/closing cover 2. When the user presses the locking means 114 to release the engagement between the main body side claw portions 1141 and the open/close cover side claw portions 21, the open/close cover 2 is opened by the repulsive force to be restored by the folded biasing means 3, and the state shown in fig. 2 is obtained.
When the user closes the opening/closing cover 2, if the user presses the opening/closing cover from above, the biasing unit 3 is bent to be in the state shown in fig. 3.
[ Effect of the embodiment ]
According to the home tissue paper storage container 100 of the present embodiment, when the user operates the locking means 114 to release the locking of the opening/closing cover 2, the urging means 3 automatically pushes up the opening/closing cover 2, and therefore, the opening of the opening/closing cover during the use of the home tissue paper becomes easy.
In particular, since the urging means 3 is formed not of a thermoplastic elastomer or a thermoplastic resin material but of a thermosetting resin material such as silicone resin, it is less likely to deteriorate, and can maintain the function as a spring for urging the opening/closing lid 2 in the opening direction, and thus the home tissue paper storage container 100 can be used for a long period of time.
Further, the home tissue paper storage container 100 can be produced so that the urging means 3 is fixed to the fixing portion 115 when the container body 1 and the opening/closing cover 2 are integrally formed by injection molding (two-color molding), and can be produced so that the container body 1, the opening/closing cover 2, and the urging means 3 are formed by pseudo three-color molding, and thus, by using the urging means 3 formed in advance of a thermosetting resin material, productivity is not lowered.
Further, since the take-out section 112 provided with the take-out hole 112a is formed of an elastic material, it is possible to apply an appropriate resistance to the household tissue paper P pulled out from the take-out hole 112a, and it is possible to appropriately hold the next household tissue paper P after the household tissue paper P stored in the storage space S is pulled out. When the household tissue paper P is roll paper, the household tissue paper P can be cut appropriately by a perforation line provided for cutting the household tissue paper P.
The container body 1 is composed of a container body upper part 11 and a container body lower part 12, which are connected to each other at the rear, whereby the container body 1 can be opened at the center part thereof, and the household tissue paper P stored in the storage space S therein can be replaced.
Therefore, when the household tissue paper P is to be replaced, the replacement work can be performed without lifting up the household tissue paper storage container 100 and while it is kept placed on a table or the like.
The container body upper part 11 and the container body lower part 12 are connected to each other at the rear, and the container body upper part 11 is rotated with respect to the container body lower part 12 with the connection part as a fulcrum, so that the storage space S can be opened and closed. Therefore, after replacement or the like, the container body upper part 11 and the container body lower part 12 can be easily fitted to each other without aligning the positions one by one, and the container body can be closed, so that the trouble of replacing the household tissue paper P inside can be reduced.
Further, the upper fitting portion 116 is formed of an elastic material in the container body upper portion 11, and the lower fitting portion 121 is formed of an elastic material in the container body lower portion 12, and these portions are fitted to each other when the container body 1 is closed, whereby the airtightness of the container body 1 can be improved. Since both the upper fitting portion 116 and the lower fitting portion 121 are formed of an elastic material, this effect can be particularly enhanced.
Further, since the lower non-slip portion 122 is formed of an elastic material on the lower surface of the container body 1, stability when the container body 1 is placed on a desk or the like can be improved.
Further, the present invention is not limited to the above embodiments.
For example, as shown in fig. 6A, the elastic material to be the fixing portion 115 may be injected so as to wrap the lower end portion of the biasing unit 3 made of a thermosetting resin material, and the biasing unit 3 may be held by the fixing portion 115 that is molded.
As shown in fig. 6B, the linear portion 115a, which is a part of the fixing portion 115 covering and holding the lower end portion of the biasing unit 3, may be disposed along the circumferential surface of the biasing unit 3. The linear portion 115a constituting a part of the fixing portion 115 can be formed by injection molding an elastic material together with the fixing portion 115.
Here, the linear portion 115a in the form of a coil spring spirally extending along the circumferential surface of the urging unit 3 is exemplified.
In this way, the repulsive force of the urging unit 3 can be adjusted by making a part of the fixing portion 115 along the circumferential surface of the urging unit 3.
In the above embodiment, the case where the fixing portion 115 is integrally formed of an elastic material with the removal portion 112 and the main body side sealing ring portion 113 has been described as an example, but the present invention is not limited to this, and for example, as shown in fig. 7, the fixing portion 115 may be integrally formed of a polyolefin resin material such as polyethylene or polypropylene with the opening/closing cover 2.
In the above embodiment, the case where the fixing portion 115 for fixing the urging unit 3 to the home tissue paper storage container 100 is provided in the container body 1 has been described as an example, but the present invention is not limited to this, and for example, as shown in fig. 8, the fixing portion 115 for fixing the urging unit 3 to the home tissue paper storage container 100 may be provided in the opening/closing lid 2.
That is, in a state where the fixing portion 115 is formed in a part of the opening/closing cover 2 formed by injection molding, the biasing unit 3 fixed to the fixing portion 115 is fixed in a state where it cannot be removed from the opening/closing cover 2 (the fixing portion 115).
In this way, the container body 1, the opening/closing cover 2, and the biasing means 3 can be formed by pseudo three-color molding so that the biasing means 3 is fixed to the opening/closing cover 2 side, thereby producing the home tissue paper storage container 100. If the urging means 3 is fixed to the fixing portion 115 injection-molded together with the opening/closing cover 2, the home tissue paper storage container 100 can be manufactured with good productivity.
In the above embodiment, the container body 1 and the opening/closing lid 2 are integrally formed by injection molding (two-color molding), but the present invention is not limited to this, and the container body 1 and the opening/closing lid 2 are formed separately, and as a result, they can be rotatably connected by a hinge or the like, although productivity is lowered.
In the above embodiment, the opening/closing lid 2 formed integrally with the container body 1 by injection molding (two-color molding) is formed of a polyolefin resin material such as polyethylene or polypropylene, but the present invention is not limited thereto, and a part or the whole of the opening/closing lid 2 formed integrally with the container body 1 by injection molding (two-color molding) may be formed of an elastic material.
The application of the present invention is not limited to the above embodiment, and can be modified as appropriate within a range not departing from the gist of the present invention.
Industrial applicability of the invention
The present invention is configured as described above, and therefore can be used as a home tissue storage container in which an opening/closing lid can be appropriately opened.
