According to the present invention, there is provided a container for housing household tissue paper that makes it easy to refill household tissue paper in the container.
Hereinafter, the container for housing household tissue paper 100 as an embodiment of the present invention is described in detail with reference to
In the following description, an X-axis, Y-axis, Z-axis, front-rear direction, left-right direction, and upper-lower direction are defined as shown in
As shown in
The container body 1 and the open/close lid 2 can be integrally formed by injection molding (double molding).
The household tissue paper P is, for example, so-called pop-up type sheets in which small wet sheets, wet tissues, or the like are folded and stacked in alternating directions such that, as one wet sheet, wet tissue, or the like is pulled out, the next one is also pulled out. Another example of the household tissue paper P is a roll sheet that is a long wet sheet, wet tissue, or the like that is wound into a roll and has perforations at regular intervals in the length direction so as to be cut along the perforations and used.
As shown in
The container body 1 and the open/close lid 2 can be integrally formed by injection molding (double molding).
The dimensions of the container body 1 as a whole are preferably 60 mm to 150 mm, more preferably 80 mm to 100 mm in the X direction, preferably 80 mm to 200 mm, more preferably 145 mm to 165 mm in the Y direction, and preferably 30 mm to 100 mm, more preferably 50 mm to 70 mm in the Z direction. The thickness of each surface is preferably 0.5 mm to 3 mm, more preferably 1 mm to 2 mm.
With such dimensions and thickness, it is possible to achieve high molding efficiency and strength that does not cause any problems in actual use.
As shown in
As shown in
Alternatively, though productivity is reduced, the upper container body 11 and the lower container body 12 can be formed separately and connected pivotably by using a hinge or the like.
The container body 1 is divided into the upper container body 11 and the lower container body 12 almost in the middle in the Z direction in the drawings, but is more preferably divided at above the middle position in the Z direction. This reduces the possibility that an end seal portion(s) of the package is pinched when the container is closed, and thereby makes it easier to refill the household tissue paper P to be stored in the container body 1 while being covered with a predetermined package.
As shown in
Furthermore, a latch 114 for opening and closing the open/close lid 2 is formed at the front portion of the upper surface, and an upper nonslip portion 115 is formed at the rear portion of the upper surface to stable the open/close lid 2 when it is opened.
Around the opening lower surface is formed an upper fitting portion 116 that fits to a lower fitting portion 121 of the lower container body 12 described later.
The outlet 112 is a hole that is formed almost in the middle of the upper surface of the upper container body and connects to the housing space S.
The outlet 112 is formed by making two intersecting cuts in
The periphery of the outlet 112 is formed of a material having elasticity described later so as to apply appropriate resistance to the household tissue paper P. As a result, when a sheet of the household tissue paper P in the housing space S is pulled out, the next sheet of the household tissue paper P is held by the outlet 112. Furthermore, when the household tissue paper P is a roll sheet, outlet 112 can cut the household tissue paper P at its perforations provided for cutting.
As shown in
As shown in
As shown in
As shown in
The upper fitting portion 116 is formed such that the upper protrusion 1161 has a dimension in the upper-lower direction of preferably 0.5 mm to 5 mm, more preferably 1 mm to 3 mm.
As shown in
In the upper container body 11, a portion forming a biasing member 3 described later, the upper nonslip portion 115, and the upper fitting portion 116 are also formed of a similar elastic material.
The other portions in the upper container body are formed of, for example, polyethylene, polypropylene, and the like.
They are integrally formed by injection molding (double molding).
When the hardness is less than the above, the elastic material is too soft and difficult to be molded, which results in poor molding efficiency. Furthermore, such a biasing member 3 cannot bias the open/close lid 2 enough in an opening direction. When the hardness is more than the above, the hard portion around the outlet 112 increases the resistance too much and makes it difficult to take out the sheet one by one and to put fingers inside the container for pulling out the sheet. Furthermore, such a biasing member 3 biases the open/close lid 2 too much in the opening direction.
Therefore, the hardness of the elastic material is preferably within the above range.
As shown in
As shown in
The lower fitting portion 121 is formed such that the lower protrusion 1211 has a size in the upper-lower direction of preferably 0.5 mm to 5 mm, more preferably 1 mm to 3 mm.
Alternatively, only the inner peripheral side of the upper protrusion 1161 of the upper fitting portion 116 and only the outer peripheral side of the lower protrusion 1211 of the lower fitting portion 121 may be each formed to protrude, such that the outer periphery of the upper protrusion 1161 fits to the inner periphery of the lower protrusion 1211.
Alternatively, the middle portion between the inner and outer peripheral sides of the upper protrusion and both of the inner and outer peripheral sides of the lower protrusion may be each formed to protrude, such that the upper protrusion fits to a recessed portion between the lower protrusions. Conversely, both of the inner and outer peripheral sides of the upper protrusion and the middle portion between the inner and outer peripheral sides of the lower protrusion may be each formed to protrude, such that the lower protrusion fits to a recessed portion between the upper protrusions.
The placed container for housing household tissue paper 100 is less likely to slip because of a lower nonslip portion 122 that is formed by providing a portion made of an elastic material on the lower surface of the lower container body 12 integrally with other portions.
The lower container body 12 has the lower fitting portion 121 and the lower nonslip portion 122 that are formed of a similar elastic material as used in the upper container body 11, and the other portions are formed of, for example, polyethylene, polypropylene, and the like.
They are integrally formed by injection molding (double molding).

They are integrally formed by injection molding (double molding).
The biasing member 3 biases the open/close lid 2 in the opening direction such that, when a user pushes the latch 114 and disengages the body-side hook 1141 and the open/close-lid-side hook 21, the open/close lid 2 is opened by pivoting on the connecting portion between the open/close lid 2 and the rear upper container body 11 as a pivot shaft.
As shown in
The biasing member 3 is formed of an elastic material such as silicone rubber and thermoplastic elastomer such as styrene-butadiene type, polyester type, polyethylene type and urethane type, that is similar to the one used in the portion surrounded by the body-side sealing loop 113 of the upper container body 11 and the like.
The biasing member 3 is formed on the upper container body 11 and the open/close lid 2 in a band shape having 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, more preferably 1 mm to 2 mm.
When the biasing member 3 is shaped to have such dimensions, it is possible to push up the open/close lid 2 without difficulty and to fold the biasing member 3 easily in the recessed portion 111 when the open/close lid 2 is in the closing state.
As shown in
When a user pushes the open/close lid from the upper side, the biasing member 3 is folded, and the open/close lid 2 is closed to be in a state shown in
[Effect from Embodiment]
According to the container for housing household tissue paper 100 according to the embodiment, when a user operates the latch 114 and disengages the opening/close lid 2, the open/close lid 2 jumps up automatically because of the biasing member 3. Therefore, it is easy to open the open/close lid when using the household tissue paper.
Furthermore, the biasing member 3 is formed of the same elastic material as the other portion(s) formed of an elastic member in the upper container body 11 and the open/close lid 2, such as the periphery of the outlet 112, and can be formed integrally with the container body 1 and the open/close lid 2. Therefore, because it is not necessary to use different materials or to increase the number of parts, the biasing member 3 does not result in less productivity.
In particular, the periphery of the outlet 112 of the upper container body 11 is preferably formed of an elastic material in order to apply moderate resistance to the household tissue paper P. According to the present embodiment, the biasing member 3 can be formed continuously from the periphery of the outlet 112. Such an embodiment is further preferred in terms of productivity because it is not necessary to prepare the biasing member 3 as an elastic material separate from the periphery of the outlet 112.
Furthermore, the body-side sealing loop 113 in the upper container body 11 and the open/close-lid-side sealing loop 22 in the open/close lid 2 are each formed of an elastic material so as to fit to each other when the open/close lid 2 is closed. As a result, the airtightness of the outlet 112, and eventually the housing space S inside the container body 1, can be improved. This effect can be particularly enhanced when both the body-side sealing loop 113 and the open/close-lid-side sealing loop 22 are made of an elastic material.
Because the upper nonslip portion 115 formed at the rear portion of open/close lid 2 on the upper surface of the container body 1 is made of an elastic material, the open/close lid 2 is more stable when it is open.
The container body 1 is constituted by the upper container body 11 and the lower container body 12 that are connected to each other at the rear surface, accordingly, the container body 1 can be opened at its middle portion, and the household tissue paper P stored in the interior housing space S can be refilled.
Therefore, it is possible to refill the household tissue paper P while the container for housing household tissue paper 100 is not lifted from but left on the table or the like.
The upper container body 11 and the lower container body 12 are connected to each other at the rear surface and relatively pivot on the connecting portion as a pivot point. In this way, the housing space S can be opened and closed. Therefore, after refilling and the like, the upper container body 11 and the lower container body 12 can easily fit to each other so that the container body is closed without aligning the positions each time. As a result, it is possible to reduce efforts at the time of refilling the inside tissue paper P.
When the container body 1 is closed, the upper fitting portion 116 formed of an elastic material in the upper container body 11 and the lower fitting portion 121 formed of an elastic material in the lower container body 12 fit to each other, and the airtightness of the container body 1 can be improved. This effect can be particularly enhanced when both the upper fitting portion 116 and the lower fitting portion 121 are made of an elastic material.
Because the lower nonslip portion 122 made of an elastic material is formed at the lower surface of the container body 1, the container body 1 can be placed more stably on the table or the like.
Furthermore, the container for housing household tissue paper 100 as a whole is made of two kinds of resin materials (an elastic material such as the silicon rubber or thermoplastic elastomer of a styrene-butadiene type, polyester type, polyethylene type, or urethane type, and a relatively hard material such as polyethylene or polypropylene), and can be integrally formed by injection molding (double molding). Therefore, excellent productivity can be also realized from the viewpoints other than the configuration of the biasing member 3 described above.
In the container for housing household tissue paper 100 described in the embodiment, the upper container body 11 and the open/close lid 2 are integrally formed, and the biasing member 3 is also integrally formed with both of them. However, the upper container body 11 and the open/close lid 2 may be formed separately and connected to each other by a hinge and the like.
In this case, the biasing member 3 may be formed integrally only with the upper container body 11, and may be formed separately from the open/close lid 2.
In this case, for example, the biasing member 3 is formed so as to protrude from the upper container body 11, and a gap for fitting to the biasing member 3 is formed in the open/close lid 2. The protrusion of the biasing member 3 is inserted into the gap, and the biasing member 3 is connected to the open/close lid 2.
Also in this case, the biasing member 3 is formed integrally with at least the upper container body 11. Therefore, the productivity can be improved as compared with the case where the biasing member 3 is formed separately from the upper container body 11 and separately from the open/close lid 2.
The biasing member 3 is not limited to be arranged as shown in the drawings. It is arranged only in one middle position in
The biasing member 3 is not limited to be formed integrally with and embedded in the upper surface of the upper container body 11 and the open/close lid 2 as shown in
For example, as shown in
When a user pushes the open/close lid from the upper side, the biasing member 3A is folded naturally, and the open/close lid 2 is closed to be in a state shown in
Such a biasing member 3A has a complicated structure as compared with the biasing member 3 according to the above embodiment, but can exert a large biasing force.
The biasing member(s) 3A is also not limited to be arranged as shown in the drawings.
There are two biasing members 3A in
The biasing member 3A is connected to the inside of the body-side sealing loop 113 and the inside of the open/close-lid-side sealing loop 22 in
The upper fitting portion 116 of the upper container body 11 and the lower fitting portion 121 of the lower container body 12 are not limited to those shown in
Because such an upper fitting portion and lower fitting portion can firmly fit to each other, the upper container body and the lower container body are unlikely to come off during usage of the container for housing household tissue paper. Furthermore, the open/close lid 2 of the upper container body is not limited to have the structure in the drawings where the biasing means 3 biases the open/close lid 2, but may have any structure as long as it can open and close the outlet 112. For example, an open/close lid 2 may not have a biasing means but formed so as to be held by a user to be opened and closed by hand every time.
The present invention is suitably applied in a technical field of manufacturing a container for housing household tissue paper.
