Description

The present invention relates to a package containing a plurality of stacked sheet-shaped objects to be packaged.

A package containing a plurality of sheet-shaped packages represented by so-called wet tissues used as daily necessities, pharmaceuticals, or cosmetics in a stacked state has been widely put into practical use. Patent Document 1 discloses an example of such a package. In this package, a plurality of stacked sheet-shaped objects to be packaged are housed in a packaging bag. The packaging bag is provided with an outlet for taking out the sheet-shaped object to be packaged. Further, in order to prevent evaporation of the liquid impregnated in the sheet-shaped packaged object, an opening / closing label is provided to open / close the outlet so that the outlet can be opened / closed. When the sheet-shaped object to be packaged is repeatedly taken out by using the package, wrinkles and deformation are likely to occur near the outlet of the package bag. Such wrinkles and deformations may prevent the opening / closing label from being hermetically adhered to the packaging bag, which is not preferable for preventing evaporation. In the package disclosed in Patent Document 1, an inner lid is adopted for the purpose of suppressing wrinkles and deformation in the vicinity of the outlet of the package bag. Further, Patent Document 2 discloses another example of a conventional package. This package has a box-shaped support inside the packaging bag. This support has higher rigidity than the packaging bag, and is configured to maintain its outer shape regardless of the amount of the sheet-shaped object to be packaged.

However, with repeated use, the number of the plurality of sheet-shaped objects to be packaged decreases, and the height of the plurality of sheet-like objects to be packaged decreases. In the package disclosed in Patent Document 1, since the inner lid is placed on a plurality of sheet-shaped objects to be packaged, the inner lid is gradually lowered by use. On the other hand, although the packaging bag made of resin or the like is flexible, the shape is maintained to some extent, so that the height of the outer shape is maintained. Therefore, the more it is used, the more a gap is created between the outlet of the packaging bag and the inner lid. When such a gap is generated, there is still a concern that wrinkles and deformation may occur in the vicinity of the outlet of the packaging bag due to further use. Further, in the package disclosed in Patent Document 2, the height of the support does not change depending on the use. Therefore, when the remaining amount of the sheet-shaped packaged material is low, the sheet-shaped packaged material is located at the back of the support and is far from the outlet of the packaged material. In such a case, it becomes difficult to take out the sheet-shaped packaged object.

Among them, polystyrene-based resin and polyester-based resin are preferable, and polyester-based resin is particularly preferable. If these resins are used, a holding force that can maintain the shape of the inner case 2 can be expected when the outlet 11 is closed by the opening / closing label 15. In addition, when the inner case 2 is pushed during use, the restoring elastic force that immediately returns to the original shape is appropriately exerted. Further, the inner case 2 can be provided with durability that does not unreasonably deteriorate even after being used a plurality of times. The thickness of the inner case 2 is not particularly limited, and in the present embodiment, it is, for example, about 200 to 600 μm, preferably 300 to 500 μm.

The top plate portion 21 is located at a position facing the upper surface of the laminated sheet-shaped packaged object 3. The top plate portion 21 is slightly larger than the sheet-shaped packaged object 3 in the z-direction, is rectangular in the present embodiment, and has four corner portions 219. The top plate portion 21 has a plurality of first easily deformable portions 231 and a plurality of second easily deformable portions 232 and a flat plate portion 211.

The plurality of first easily deformable portions 231 are linear portions extending radially from the outside to the inside in the z-direction view. In the present embodiment, the four first deformable portions 231 extend inward from the four corner portions 219 of the top plate portion 21. The first easily deformable portion 231 is a linear portion configured to be more easily deformed than the peripheral portion thereof.

The specific configuration of the first easily deformable portion 231 is not particularly limited, and in the present embodiment, as shown in FIG. 4, a part of the top plate portion 21 is curved to one side in the z direction (lower side in the figure). It is a shaped shape. The illustrated first easily deformable portion 231 has a semicircular cross section, but various shapes such as a mountain cross section and a U-shaped cross section can be selected as long as they fulfill a desired deformation function.

The plurality of second easily deformable portions 232 are linear portions having a shape along the peripheral edge 218 of the top plate portion 21 in the z-direction view. The size of the plurality of second deformable portions 232 is smaller than that of the peripheral edge 218. In the illustrated example, three second deformable portions 232 having different sizes are arranged concentrically. In the illustrated example, the innermost second easily deformable portion 232 is provided so as to connect the inner ends of the plurality of first easily deformable portions 231. Further, the other two second easily deformable portions 232 are provided so as to intersect with the plurality of first easily deformable portions 231.

The shape of the second easily deformable portion 232 is not particularly limited, and in the present embodiment, it has a rectangular shape in the z-direction. The specific configuration of the second easily deformable portion 232 is not particularly limited, and in the present embodiment, as shown in FIG. 5, a part of the top plate portion 21 is curved to one side in the z direction (lower side in the figure). It is a shaped shape. The illustrated second easily deformable portion 232 has a semicircular cross section, but various shapes such as a chevron shape in a cross section and a U shape in a cross section can be selected as long as they fulfill a desired deformation function.

The flat plate portion 211 is a portion located inward from the inner end of the plurality of first easily deformable portions 231. In FIGS. 1 and 2, for convenience of understanding, the flat plate portion 211 is provided with hatches composed of a plurality of discrete points. In the present embodiment, the z-direction rectangular portion located inward from the inner end of the four first easily deformable portions 231 is the flat plate portion 211. Further, in the present embodiment, the innermost second easily deformable portion 232 is provided at the outer end of the flat plate portion 211. In other words, the second easily deformable portion 232 has a function of clarifying the outer end of the flat plate portion 211. In the illustrated example, the flat plate portion 211 is a flat plate-shaped portion, but even if the package A1 has a shape having minute irregularities or gentle waviness depending on the shape of the package A1 and the purpose of use. good.

An inner outlet 212 is formed in the flat plate portion 211. The inner outlet 212 penetrates the flat plate portion 211 and is provided at a position overlapping the outlet 11 of the packaging bag 1 in a plan view. The specific configuration of the inner outlet 212 is not particularly limited as long as it has a size and shape that allows the sheet-shaped packaged object 3 to be taken out of the inner case 2. In the illustrated example, the inner outlet 212 is an elliptical opening in a plan view provided substantially in the center of the flat plate portion 211, and may be a rectangular opening in a plan view or the like. Further, the inner outlet 212 may be a cutting line such as a straight line or a cross shape. By arbitrarily setting the size and shape of the inner outlet 212, it is possible to control the state in which the sheet-shaped packaged object 3 is taken out. For example, by making the inner outlet 212 a relatively large opening, it is possible to smoothly take out a thick sheet-shaped packaged object 3 or a sheet-shaped packaged object 3 stacked on a plurality of sheets. On the other hand, by making the inner outlet 212 a relatively small opening or a cutting line, it is possible to prevent a large amount of the sheet-shaped packaged object 3 from being unintentionally taken out.

The side plate portion 22 is connected to the peripheral edge 218 of the top plate portion 21 and extends in the z direction. The side plate portion 22 surrounds a plurality of sheet-shaped objects to be packaged 3 in the x-direction and the y-direction. In the present embodiment, the side plate portion 22 is provided with a plurality of third easily deformable portions 233. The plurality of third easily deformable portions 233 are connected to the outer ends of the plurality of flat plate portions 211, and extend downward from the corner portions 219 of the top plate portion 21 in the z direction. In the present embodiment, the third easily deformable portion 233 has a length of about half the height of the side plate portion 22 in the z direction.

The specific configuration of the third easily deformable portion 233 is not particularly limited, and in the present embodiment, a part of the side plate portion 22 is in the z-direction view as in the first easily deformable portion 231 and the second easily deformable portion 232. It is a shape curved in the direction. The third easily deformable portion 233 has, for example, a semicircular cross section, but various shapes such as a chevron shape in a cross section and a U shape in a cross section can be selected as long as it fulfills a desired deformation function.

6 to 9 show one process of taking out the sheet-shaped packaged object 3 from the outlet 11 and the inner outlet 212 in a state where the quantity of the plurality of sheet-shaped packaged objects 3 is reduced by use. .. In FIG. 6, the packaging bag 1 is omitted for convenience of understanding, and FIG. 7 is a cross-sectional view taken along the line VII-VII of FIG. 8 and 9 are enlarged cross-sectional views of a main part showing the same points as those of FIGS. 4 and 5.

In the illustrated state, since the quantity of the plurality of sheet-shaped objects to be packaged 3 is reduced, the height of the plurality of sheet-shaped objects to be packaged 3 in the z direction is lower than that in the states shown in FIGS. 1 and 3. It has become. On the other hand, the z-direction dimension of the side plate portion 22 of the inner case 2 does not change with use. Therefore, before the operation of taking out the sheet-shaped packaged object 3, a gap is formed between the upper surface of the plurality of sheet-shaped packaged objects 3 in the z direction and the flat plate portion 211 of the inner case 2. .. Further, since the packaging bag 1 is supported by the inner case 2, it is in a state substantially similar to the state shown in FIG. 2 before the operation of taking out the sheet-shaped packaged object 3.

In order to take out the sheet-shaped packaged object 3, first, as shown in FIG. 7, the opening / closing label 15 is opened, and the outlet 11 and the inner outlet 212 are exposed. Next, as shown in FIGS. 6 and 7, the top plate is such that the inner outlet 212 of the inner case 2 is brought closer to the upper surface of the plurality of sheet-shaped packages 3 whose height in the z direction is lowered in the z direction. The flat plate portion 211 of the portion 21 is pushed downward in the z direction. This pressing may push only the flat plate portion 211, or may push the flat plate portion 211 together with a part of the packaging bag 1. By this pressing, the flat plate portion 211 moves downward in the z direction with respect to the upper end of the side plate portion 22 in the z direction. At this time, as shown in FIG. 8, the plurality of first deformable portions 231 exhibit deformation behavior such that the width becomes narrow. As a result, the portion of the top plate portion 21 that surrounds the flat plate portion 211 is tilted diagonally, and the flat plate portion 211 is allowed to move downward in the z direction.

Further, among the plurality of second easily deformable portions 232, the innermost one (the one located at the outer end of the flat plate portion 211) exhibits a deformation behavior such as being slightly bent as shown in FIG. This contributes to making the flat plate portion 211 take a so-called horizontal posture along the x-direction and the y-direction, although the portion of the top plate portion 21 surrounding the flat plate portion 211 is in an inclined posture. Further, the other two second easily deformable portions 232 show a deformation behavior such that the width becomes wider so as to promote the downward movement of the flat plate portion 211 in the z direction.

Further, the plurality of third easily deformable portions 233 show deformation behavior that promotes the z-direction upper portion of the side plate portion 22 to collapse inward. This deformation behavior is, for example, a deformation behavior in which the width of the third easily deformable portion 233 is narrowed.

Due to the deformation behavior of the plurality of first deformable portions 231 and the plurality of second easily deformable portions 232 and the plurality of third easily deformable portions 233 due to such pressing, the flat plate portion 211 is formed by the plurality of sheet-shaped packaged objects 3. Close to the upper surface in the z direction. In this state, the user takes out one or a plurality of sheet-shaped packaged objects 3 by an operation such as picking up the uppermost sheet-shaped packaged object 3 through the outlet 11 and the inner outlet 212. ..

After the sheet-shaped packaged object 3 is taken out, the above-mentioned pressing is released. As a result, the plurality of first deformable portions 231 and the plurality of second easily deformable portions 232 and the plurality of third easily deformable portions 233 return from the deformed state to the original state. As a result, the shape of the inner case 2 is restored to the shape shown in FIGS. 1 and 3, and the packaging bag 1 takes the state shown in FIGS. 1 and 3 accordingly.

Next, the operation of the package A1 will be described.

According to the present embodiment, since the plurality of first easily deformable portions 231 are provided, when the flat plate portion 211 is pressed downward in the z direction, the plurality of first easily deformable portions 231 are lowered of the flat plate portion 211. Shows deformation behavior that encourages. As a result, the flat plate portion 211 can be lowered while the deformation of the flat plate portion 211 itself is suppressed. Further, by selectively deforming the plurality of first easily deformable portions 231, it is possible to prevent unnecessary deformation from occurring in unintended portions of the top plate portion 21 other than the plurality of first easily deformable portions 231. .. On the other hand, when the pressing is released, the plurality of first deformable portions 231 are restored to the original state, and the flat plate portion 211 rises to the state shown in FIGS. 1 and 3. Further, since the unnecessary deformation of the unintended portion of the top plate portion 21 is avoided, the unintended portion remains deformed even after the pressing is released. This makes it possible to prevent the flat plate portion 211 from being hindered from rising. As described above, in the present embodiment, it is possible to repeatedly take out the sheet-shaped packaged object 3 while keeping the flat plate portion 211 in a flat state. Therefore, it is possible to suppress the occurrence of wrinkles and deformation in the portion of the packaging bag 1 supported by the flat plate portion 211, and it is possible to more appropriately maintain the airtightness by the opening / closing label 15. Further, even if the remaining amount of the sheet-shaped packaged object 3 is reduced by use, the flat plate portion 211 can be raised and lowered, so that the outlet 11 can be smoothly brought closer to the sheet-shaped packaged object 3. This makes it possible to avoid a situation in which it becomes difficult to take out the sheet-shaped packaged object 3.

In the present embodiment, the top plate portion 21 has a rectangular shape, which is an example of a polygonal shape. The plurality of first deformable portions 231 extend inward from the corner portions 219 of the top plate portion 21. The plurality of first deformable portions 231 having such a configuration are inclined toward the portion of the top plate portion 21 that surrounds the flat plate portion 211 so that the flat plate portion 211 is smoothly lowered when the flat plate portion 211 is pressed. Suitable for taking a good posture.

Further, by providing the plurality of second easily deformable portions 232, the flat plate portion 211 can be lowered and raised more smoothly. More specifically, the innermost second easily deformable portion 232 contributes to more reliably maintaining the shape of the flat plate portion 211. Further, the provision of the other two second easily deformable portions 232 causes an extension behavior due to pressing. Thereby, the lowering of the flat plate portion 211 can be promoted. Further, by providing the plurality of second easily deformable portions 232, it is possible to avoid unnecessary deformation of the unintended portion of the top plate portion 21. As a result, it is possible to prevent the unintended portion of the top plate portion 21 from being left deformed after the pressing is released, and the flat plate portion 211 from being hindered from rising.

Further, since the plurality of third easily deformable portions 233 are provided, it is possible to promote the behavior of the side plate portion 22 to collapse inward when the flat plate portion 211 is pressed, and the flat plate portion 211 can be smoothly lowered. Is preferable. Further, by providing the plurality of third easily deformable portions 233, it is possible to avoid unnecessary deformation of the unintended portion of the side plate portion 22. As a result, it is possible to prevent the unintended portion of the side plate portion 22 from being left deformed after the pressing is released, and the flat plate portion 211 from being hindered from rising.

The second easily deformable portion 232 connects the inner ends of the plurality of first easily deformable portions 231 and is provided at the outer end of the flat plate portion 211.

Even with such a modification, the flat plate portion 211 can be smoothly raised and lowered while being kept flat. As can be understood from this modification, the configuration of the second easily deformable portion 232 can be appropriately set according to the magnitude of the z-direction distance for lowering the flat plate portion 211. For example, a configuration may be adopted in which a plurality of first deformable portions 231 are provided, while the second easily deformable portion 232 and the third easily deformable portion 233 are not provided. Alternatively, as shown in FIG. 10, instead of the second easily deformable portion 232 that partially surrounds the entire circumference of the flat plate portion 211, the second easily deformable portion 232 that partially surrounds the flat plate portion 211 may be adopted.

FIG. 11 shows a second embodiment of the present invention. The package A2 of the present embodiment is different from the package A1 in the z-direction view shape of the inner case 2. In the present embodiment, the inner case 2 has a hexagonal shape in the z-direction. That is, the package A1 and the package A2 show a configuration example in which the inner case 2 has a polygonal shape in the z-direction view. In the illustrated example, the plurality of sheet-shaped packaged objects 3 are shown as rectangular objects in the z-direction, but even if a hexagonal sheet-shaped packaged object 3 other than the rectangular shape is adopted. good.
