  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, below, the tissue paper storage container which stores tissue paper is illustrated as a sanitary paper storage container.

(Example of configuration of tissue paper container)
FIG. 1 is a perspective view of a tissue paper container for explaining the formation position of a fold line. Here, a rectangular top surface portion 1 configured by a pair of opposing long sides 11 and a pair of opposing short sides 12, a pair of opposing long sides 21 and a opposing short side 22 orthogonal thereto A rectangular parallelepiped shaped paper tissue paper container (hereinafter simply referred to as simply formed by a rectangular bottom portion 2 constituted by a pair of four sides and a pair of side portions 3 and a pair of side portions 4 connecting them) Also referred to as a container). Here, the top surface portion 1 is a surface on which the tissue paper outlet 10 is formed, and the outlet 10 is closed by the lid 15 before use. The lid portion 15 is formed by performing perforation processing on the portion of the top surface portion 1 corresponding to the periphery of the outlet 10, and in use, the outlet portion 10 may be exposed by separating the lid portion 15 at the perforated portion. it can. A plastic film 17 (see FIGS. 3 to 5) in which slits are formed in the longitudinal direction is attached to the back surface side of the top surface portion 1 so as to cover the entire outlet 10.

  In the following description, the side surface 3 connected with the top surface 1 and the bottom surface 2 by the long sides 11 and 21 respectively, that is, the surface extending in the longitudinal direction is a wide surface, and the side surface 4 connected with the short sides 12 and 22, respectively The surface extending in the direction may be referred to as a narrow surface.

  In the present embodiment, both ends of the long side 11 on the top surface 1 are connected, that is, a bent curve 31 that is curved in an arc shape that is convex downward, and a long side on the bottom side The wide surface 3 is formed by connecting both ends of the curved portion 21 and forming an arc-shaped bent curve 32 that is convex upward. In the following, the folds 31 and 32 may be referred to as a top side fold and a bottom side fold, respectively. Furthermore, a perforation is formed to overlap at least a part of the top surface side folding line 31 and the bottom surface side folding line 32. In the present embodiment, as shown in FIG. 2A (the figure shows only the top side folding curve 31 for simplification), perforations are provided over the entire lengths of the folding lines 31 and 32. 30 are formed continuously. However, as shown to the same figure (b), it may be provided in the center part C, conversely, as shown to the same figure (c), it may be provided in the both ends E. Moreover, as shown to the same figure (d), the formation area 30a of perforations may be provided intermittently.

  It can be determined in consideration of the ease of the bending operation, the difficulty of generating wrinkles, the maintainability of the bent shape, the appearance, etc. as to which of these are adopted. In addition, the perforation of the same form does not need to be formed in all the bending lines.

  FIGS. 3 (a), (b) to 5 (a), (b) illustrate an operation to be performed when the remaining amount of tissue paper stored is low. (A) and (b) of each figure are respectively a perspective view and a longitudinal cross-sectional view showing a deformed state of the container when it is bent along a folding line.

  The use of the container is started, and the surface of the loaded tissue paper P is lowered as the remaining amount of tissue paper decreases. If the use is continued in that state, a part of the tissue paper PE laminated at the top, which is sandwiched between the slits of the plastic film 17, will come out of the slits and fall into the inside of the container, making it difficult to take out. In that case, when the user presses the long side 11 of the top surface 1 toward the bottom surface 2, as shown in FIGS. 3A and 3B, the top surface 1 is curved downward. The wide surface 3 has a shape in which the top surface side is curved downward. That is, the container is deformed into a barrel shape as viewed from the top surface side, and a concave lens shape in which the top surface side is curved downward in a side view. Then, since the longitudinal central portion of the outlet 10 or the plastic film 17 is in proximity to the uppermost tissue paper, it is possible to maintain the take-out property without causing the plastic film 17 to be removed from the slit. .

  Alternatively, an operation may be performed to first press the long side 21 of the bottom surface 2 toward the top surface 1. In this case, as shown in FIGS. 4A and 4B, the bottom portion 2 forms a curved surface that curves upward, and the wide surface 3 curves downward from a bottom side bending curve 32 that the bottom surface curves upward. It becomes a shape that That is, the container is deformed into a barrel shape as viewed from the bottom surface, and a concave lens shape in which the top surface side curved line is curved downward in a side view. Then, since the longitudinal central portion of the taking out port 10 or the plastic film 17 is in proximity to the tissue paper PE at the top, the takeout property can be maintained without the plastic film 17 coming out of the slit. it can.

  Either one of the operations in FIGS. 3 (a) and 3 (b) and FIGS. 4 (a) and 4 (b) may be performed first, but if the remaining amount of tissue paper is further reduced, the other operation is performed. By performing the operation, the deformed state as shown in FIGS. 5 (a) and 5 (b) can be obtained. This deformation state is advantageous because the distance between the top surface portion 1 and the bottom surface portion 2 can be further reduced, so that it can be coped with even when the remaining amount of tissue paper is considerably reduced. In the deformed state of the container shown in FIGS. 5A and 5B, two long sides 11 on the top surface 1 side and two lengths on the bottom surface 2 side are not sequentially performed. It can also be obtained by attaching a finger to the side 21 and simultaneously performing the pressing operation and the pressing operation.

(Conditions for forming folds)
With reference to FIG. 6, the preferable formation aspect of a bending line is demonstrated. Although only the top side folding line 31 is shown for simplification, the same applies to the bottom side folding line 32 if it is considered upside down.

  The angle α between the ridgeline 34 formed by the wide surface 3 and the side surface 4 adjacent thereto and the folding line 31 passing through the corner on the top surface 1 side increases as the curvature of the folding line 31 increases, and decreases as it decreases. Become. In other words, the vertical distance D from the top surface portion 1 to the center of the fold line 31 becomes smaller as the curvature of the fold line 31 becomes larger, and becomes larger as it becomes smaller.

  If the distance D in the vertical direction from the top surface 1 to the center of the folding line 31 is too small, the amount of reduction of the internal dimension in the height direction between the top surface 1 and the bottom 2 due to bending becomes small, and the remaining tissue paper Unfavorably because it becomes difficult to take out when the amount decreases. In addition, depending on the material (paper quality) "Kosi" of the container, it is possible that it will be restored easily.

  On the other hand, if the distance D is too large, the angle α becomes more acute, which may cause aesthetic problems or the appearance of sharp portions on the top surface portion 1.

  Taking the above into consideration, the inventor also considers the relationship between the distance D and the height H, taking into consideration the occurrence of wrinkles when bent and the provision of the bending curve 32 on the side of the bottom portion 2 as well. did. As a result, the distance D is preferably 15% or more and less than 50% of the height H of the container, more preferably 25% or more and 40% or less, and still more preferably 30% or more and 35% or less The findings of the In the present embodiment, D / H = 1/3 (about 33%).

(Others)
The present invention is not limited to the above-described embodiment or the variations described above, and other configurations can be adopted.

  For example, in the embodiment described above, the configuration in which both the top surface side folding line 31 and the bottom surface side folding line 32 are provided has been described. However, only one of them may be provided as long as the function of maintaining the removability of the tissue paper is achieved. In this case, the deformation operation of the container shown in FIG. 4 (a), (b) or FIG. 5 (a), (b) may be performed.

  Further, the perforation of the present invention is intended to facilitate the bending operation and to allow the tissue paper container to stably maintain the deformed shape after bending. As is clear from b) to (d), it is not essential to perform breakage along the perforations. However, in the configuration in which perforations are continuously formed over the entire length of the bending line as shown in FIG. In this case, even if breakage occurs during use of the container, both sides of the breakage line remain butted unless the breakage line is opened if the container retains the usual storage shape. Invasion of dust and the like does not substantially occur. In addition, when the remaining amount of tissue is low, it can be broken and refilled. In particular, FIG. 7 shows an example in which the container is expanded after use into a blank state. Here, corresponding reference numerals are attached in parentheses to the areas corresponding to the respective parts described with reference to FIG. 1 (note that the reference numeral 5 is an area to be the pasting part). In this case, the container blank can be finely cut into five parts of the portions 61 to 65 by performing the breaking operation of the perforations along the folding lines 31 and 32. Can also contribute to facilitating disposal.

  In addition, the embodiment described above exemplifies a rectangular parallelepiped shaped container having a rectangular top surface portion and a bottom surface portion configured by a pair of opposing long sides and a pair of opposing short sides orthogonal thereto. However, the present invention is not limited to this, and can also be applied to, for example, a rectangular parallelepiped shaped container having a square top and bottom portion.

  Furthermore, the present invention is applicable not only to tissue paper but also to containers for storing sanitary paper such as paper towels. Further, the material of the container is not limited to paper, and may be plastic as long as the ease of bending operation is ensured.
