Abstract

This eliminates the risk of fingers getting stained with the medication, and the risk of the dirt on the fingers mixing with the remaining medication, thus compromising cleanliness. [Solution] The storage container 10 has both an expandable section 6 and a fan-shaped pivot near where the center line 9 in the short direction 8 intersects the front and rear long sides of the long side that straddle the center line 14 in the longitudinal direction 5. The fan-shaped pivot of the expandable section 6 is fixed and when bent downward 41, the fan-shaped expandable section 6 expands, and the fan-shaped pivot on the bent bottom surface forms a mountain shape. The distance between the tip of the mountain shape and the dispensing opening 7 is reduced from the distance before bending, allowing the sanitary paper on the top surface of the laminate to be picked up and removed.

Description

Technical Field

[0001] The present invention relates to a toilet paper package containing a laminate of toilet paper.

Background Art

[0002] In the configuration of a conventional package in which a laminate of dry or wet sheets is enclosed together with a storage container, when used repeatedly, the height of the laminate gradually decreases, and the sheet is taken out from the extraction opening by pinching it from the bottom surface with a finger.

[0003] Japanese Patent Application Laid-Open No. 2023-057946 discloses, in paragraph

[0029] , "Next, in addition to FIGS. 2 and 3 above, referring to FIGS. 5 to 8, the structure of the tray body 2a will be described. FIGS. 5 and 8 are a top view of the tray body 2a and a side view of the side surface 19 of the tray body 2a, respectively.~The tray body 2a includes a bottom plate 10 for placing a plurality of wet sheets. This bottom plate 10 is arranged near the central portion of the bottom plate 10, and has a resin deformation portion 5 whose shape can be switched between a concave shape and a convex shape, and a peripheral wall portion 12 that surrounds the deformation portion 5 and rises from the flat portion 10a of the bottom plate 10.~It has a circular shape." And in paragraph

[0030] , "The above-described deformation portion 5 is a single plate-like member whose upper and lower surfaces are composed of curved surfaces (a part of a spherical surface). When it is in the concave shape shown in FIGS. 2 and 6, when the lower surface side is pushed up with a pressing force of a predetermined magnitude or more, it is deformed into the convex shape (dome shape) shown in FIGS. 3 and 7, and when it is in this convex shape, when the upper surface side is pushed down with a pressing force of a predetermined magnitude or more, it is deformed (returned) into the concave shape shown in FIGS. 2 and 6.~."

[0004] Japanese Patent Application No. 2025-025635 discloses, in paragraph

[0066] , "It is preferable that one or more fixing mechanisms 54 and 56 are provided on one of 53 and 55 according to the bulk of the laminate 2 during use. Alternatively, a mechanism may be provided in which a part of the cut shape of the bottom surface 22 of the box 1 has a position 61 that breaks the bottom surface 9 of the lower surface 8 of the laminate 2 and pushes it up temporarily in the direction of 49 above the extraction opening 7."

[0005] In these packages with freely opening and closing openings, as the height of the internal laminate gradually decreases, the top sheet of the laminate at the bottom of the package is difficult to remove by pinching it with one's fingers. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2023-057946 [Patent Document 2] Patent Application No. 2025-025635 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] Conventional technology, especially during use, causes the height of the stacked layers in the container to gradually decrease. Users have to grope deep into the bottom of the container with their thumb and index finger to find the opening for picking up the sheet at the bottom, probably inserting their fingertips up to where their nail art is, and then forcibly picking up the top sheet while still groping around. Therefore, a design is needed to allow for smoother picking and removal.

[0008] Furthermore, inserting your fingers deeper reveals that the process differs significantly between the initial use after opening the package and the process as the stack gradually shrinks, making it difficult. Working at the bottom of the bag involves working by feel, which carries risks such as getting your fingers dirty with the liquid, the dirt mixing with the remaining liquid and compromising cleanliness, and accidentally picking up multiple sheets. Improvements are needed to eliminate these inconveniences and make the cosmetic application process more enjoyable. [Means for solving the problem]

[0009] The present invention provides a sanitary paper packaging comprising a bag and a storage container disposed inside the bag for storing a laminate of sanitary paper, wherein the storage container is composed of a pair of long sides extending in the longitudinal direction, a pair of short sides extending in the transverse direction, and a bottom surface connecting the pair of long sides and the pair of short sides, and has an open top surface opposite the bottom surface, and near the longitudinal center of the pair of long sides, expandable parts are formed on the pair of long sides to allow the bottom surface to bend around a curved part near the longitudinal center of the bottom surface, the bag comprises an opening for taking out the sanitary paper stored in the storage container formed near the center of the top surface of the bag, and a lid for opening or closing the opening, and the sanitary paper packaging solves the problem by facilitating the removal of the sanitary paper from the top surface of the laminate from the opening in the bag, as the height of the laminate gradually decreases as the sanitary paper is used, by bending the bottom surface of the storage container and pushing up the area near the center of the laminate. [Effects of the Invention]

[0010] The dispensing opening of the present invention makes it easy to push up the top surface of the laminate from the bottom surface of the storage container, even if the height of the top surface of the laminate gradually decreases during use. Therefore, it is possible to provide a product that allows you to easily pick up and lift out each sheet one by one, just as you would when you first start using it.

[0011] This invention makes it easy to push the top surface of the laminate from the bottom of the container to a predetermined distance from the dispensing opening, eliminating the need to insert fingers deeply and allowing the top sheet to be picked up by pinching. Conventional products require users to grope around when picking up the bottom sheet, which can lead to fingers getting dirty with the liquid, contamination of the remaining liquid with the liquid and compromising cleanliness, and the risk of missing multiple sheets during the picking process. [Brief explanation of the drawing]

[0012] [Figure 1] This is a perspective view of a packaging body having a storage container according to the present invention. [Figure 2] This is a perspective view of an embodiment in which a portion of the laminate of the present invention is pushed up. [Figure 3] These are a cross-sectional view and a perspective view of the storage container of the present invention, showing the bottom of which is bent in the shorter direction. [Figure 4] This is a process diagram showing the manufacturing process of the present invention. [Modes for carrying out the invention]

[0013] The present invention relates to a mechanism (hereinafter referred to as "mechanism") 47 that allows the user to fold the bottom 30 of the storage container with both hands to push up the top surface 25 of the stacked stack, whose height 36 has gradually decreased, towards the vicinity of the opening 7. This mechanism aims to alleviate the user's arduous task of inserting their thumb and index finger deep into the bottom 30 of the storage container through the opening 7 to pick up one of the sheets 4 located at the bottom 30 of the storage container.

[0014] The mechanism 47 is present in the form shown in Figures C, D, E, and F on the sanitary paper packaging 57 of Figure 1, having a pair of short sides 23, 24 and a pair of long sides 39, 40 of the storage container 10 of the first embodiment, and in the form shown in Figures G, H, I, J, K, L, M, and N on the plate body 72 of the storage container 10, which is the support member 74 of the laminate of the second embodiment, and in all figures a bendable portion 73 is formed that allows the bottom surface 30 to be folded along the center line 9 in the short direction.

[0015] The form of the mechanism 47 has a shape of a curved portion 55 that curves or is bent along the center line 9 in the short side direction of the pair of long side surfaces or cross-sections of the bottom 30 of the storage container, having a determined bending angle 63 and a determined distance 68 of the extension of the top. Each time the continuous mountain shape 46 is formed with the left and right hands, the tip 48 of the continuous mountain shape, the upper surface 25 of the laminate, and the outlet 7 have a distance 49 close to each other each time, thus solving the problem of freeing the user with nail art from difficult operations. The form after the removal operation is completed returns to its original state when placed on a flat surface such as a table, with the bent mechanism 47 straightening out.

[0016] The bent portion 73 has a determined bending angle 63 near the central portion 37 of the storage container 10 of the present application. When the bent portion 73 is bent in the bending direction 16 centered on 73, it is configured such that the top 67 of the fan-shaped surface, which has been pre-bent, extends to a determined distance 68 of the extension of the top. By the operation of bending to reduce the angle, a distance close to the determined distance 68 can be obtained as the determined angle 63 approaches the closing angle 64. The angle is such that there is one or more hole portions along the center line 9 in the short side direction, or there are recesses on one or both sides of the front and back of the plate 27 of the bottom 30, or the notch area 78 of the notched area provided with a cut line allows an angle in the 64 direction closed from the determined angle 63 to be obtained.

[0017] The sanitary paper 11 will be described, for example, with respect to a wet tissue or a face mask (hereinafter referred to as "sheet") 4 in which a laminate 2 containing a chemical solution is enclosed in a storage container 10 in a state where the chemical solution has penetrated into a bag body 1 of a resin film 32 having barrier properties. It is not a problem if the laminate 2 of the dry sanitary paper 11 is enclosed in the storage container 10 in a packaging body regardless of the barrier properties.

[0018] The first embodiment will be described.

[0019] The first embodiment is illustrated in FIGS. 1, C, D, E, and F.

[0020] That is, in the telescopic part 6 of FIG. C, the fan-shaped part 44 in the closed state with the determined distance of the top 67 of the pre-expanded fan surface is bent in the bending direction 16 with the key part 17 of the fan fixed to the left and right side surfaces 23 and 24 of FIG. D, and the fan surface expands in a curved shape and spreads to the top 67 of the fan surface with the determined distance. At the same time, the folded mountain shape 46 of the bottom surface 30 is formed, and the curved tip 48 moves a determined distance in the direction of the outlet 7, having a distance 49 close to the upper surface 25 of the laminate and the outlet 7, and is configured to be able to smoothly pick and take out the sheet 4 on the upper surface 25 of the laminate.

[0021] The fan-shaped part 44 is a tool for creating wind and taking in coolness. It has a shaft passing through one side with a key part 17 made of bamboo, wood, or plastic as its frame, and has the top 67 of the fan surface that spreads out at the front. It is made by pasting paper, cloth, etc. so that it can be folded. It is provided near the center 37 of the pair of long side surfaces 39 and 40 of the storage container 10. When the pair of left and right short side surfaces 23 and 24 are bent in the bending direction 16, the top 67 of the determined fan surface with the key part 17 as the center has a determined extension distance 68.

[0022] In addition, FIG. E has one or more diamond shapes 69 with holes in one or more middle ribs in a curved shape when the left and right side surfaces 23 and 24 are bent in the bending direction 16 with the key part 17 of the fan as the center. FIG. F has a mechanism that expands to a determined distance 71 extending horizontally in a deformed diamond shape 70 that is horizontally compressed and extended when bent in the bending direction 16. For example, it is not a problem even if a part of the four corners of the diamond shape 69 devised for easy opening is in an open state.

[0023] A rhombus is a quadrilateral in which all four sides are of equal length. The rhombus shape 69 in Figure E has multiple holes enclosed by four frames, arranged in a fan shape from the pivot point 17 to the top 26 of the fan-shaped surface 67. When the pair of short sides 23 and 24 are bent in the bending direction 16, the rhombus shape 69 in Figure F is pulled and stretched laterally to become a deformed rhombus 70 with a predetermined distance 71, and the top extension has a predetermined distance 68. Alternatively, it may be a circle with multiple holes, or a polygon with multiple sides, which deforms in the longitudinal direction 5 when bent.

[0024] In other words, the mechanism 47 has a region that folds along the center line 9 in the shorter direction, and the bottom surface 30 in the longer direction 5, or the center line 9 in the shorter direction of the plate body 72 in the longer direction 5, is folded, and there is a distance 49 where the vicinity of the bent central part 37 and the dispensing opening 7 are close together.

[0025] The rectangular bottom surface 30 of the storage container 56 has a pair of long sides 39, 40 and a pair of short sides 23, 24 that are continuous with the edges of the four sides of the bottom surface 30, for further holding the stacked body 2 in place.

[0026] The bottom surface 30 of the storage container has a pivot point 17, which is an angled part of the bottom 30. The left and right ends 21 and 22 are grasped symmetrically along the center line 9 in the shorter direction 8, and the 21 and 22 are bent down to a certain position. A part of the bottom 30 is omitted along the center line 9 for bending to a bending line 31 from position 9. The pivot point 17 prevents the extension distance of the top 67 of the fan-shaped surface from bending more than necessary, and has a predetermined angle 63 and 67 with a predetermined extension distance.

[0027] In other words, it has a bag body 1, a storage container 10 located inside the bag body 1 35 for storing a laminate 2 of sanitary paper 11, a pivot part 17, and a sanitary paper packaging body 57 with predetermined angles 63 and 67 that prevent the pre-extended distance of the top 67 of the fan-shaped surface from bending more than necessary. After the sheet 4 on the top surface 25 of the laminate is picked out, the bend 30 returns to a flat state due to its own weight when placed on a table or the like, except in special circumstances.

[0028] In Figure 1 of the present invention, the center line 14 along the longitudinal direction 5 of the top surface 3 of the bag 1, the center line 14 along the longitudinal direction of the storage container 10, and the center line 14 along the longitudinal direction of the laminated body 2 enclosed in the storage container 10 are all positioned aligned along the longitudinal direction 5.

[0029] The bag body 1 has a storage container 10 inside 35, and has sides A 12 and B 13 on either side of the longitudinal center line 14 of the top surface 3. Near the center 37 where 14 and the transverse center line 9 intersect, there is an opening 7 fixed with an adhesive part 33 for pinching and taking out the sheet 4, and a lid 18 that closes the opening 7. The 18 separates the inside 35 from the outside 37, maintaining the safety and stability of the inside 35.

[0030] Figures C, D, E, and F show a three-dimensional storage container 10 that houses the laminated body 2 from above. The storage container has a longitudinal surface A 12 and a longitudinal surface B 13 flanking the center line 14 of the storage container. The shape is such that the left side surface 23, the front long side surface 39, the right side surface 24, and the rear long side surface 40 are continuous on the bottom surface 47, forming the storage container 10.

[0031] The storage container 10 has a telescopic section 6 on the long sides 39 and 40 in the longitudinal direction 5, near the center 37 where the center line 14 extending in the longitudinal direction 5 of the storage container 10 intersects with the center lines 9 extending in the short direction of both long sides 39 and 40. When the left end 21 and the right end 22 are bent in different directions 16 around the pivot 17 of the fan located on the bottom surface 47, which is held in place by the fingertips of both hands, the telescopic section 6 on the upper part 51 of the long sides 39 and 40 extends a distance 15 that the curved shape of the fan opens, and at the same time, the mountain shape 47 created as the bottom surface 47 of the storage container 10 is bent approaches a distance 49 that moves closer to the direction of the opening 7.

[0032] In this invention, the upper surface 25 of the laminate approaches the dispensing opening 7. Therefore, when the mountain shape 47 formed by the shrinking portion 6 and the distance 49 approaching the dispensing opening 7 are formed, the sheet 4 on the upper surface 25 of the laminate can be easily grasped with fingers and pulled out from the dispensing opening 7, eliminating the troublesome and difficult work risks associated with conventional products.

[0033] The telescopic part 6 has a bellows shape 43, or a wave shape 19, or it has a fan shape 44 (hereinafter referred to as the "telescopic part") 6 that extends and curves outwards from the pivot points 17 of both long sides 39 and 40 of the fan, in the direction 16 in which the upper part 26 bends, and has a distance 15 that extends and spreads out, so that the fan spreads out and the tip extends 16. When the fan is closed, the distance 16 that extends returns to the state before extension and contraction. To facilitate the folding process, it is preferable to have a space 52 on the left between the bag body 1 and the left end 21, and a space 53 on the right between the bag body 1 and the right end 22, after verification and provision of play.

[0034] Figures C to D of the storage container 10 show that it has expandable sections 6 on both the long sides 39 and 40 near the center 37 where the longitudinal center line 14 and the transverse center line 9 intersect. By grasping the left and right ends 21 and 22 and placing the fingertips on the fan-shaped pivot 17 that fixes the area near the bend line 31 of the bottom surface 47, both left and right ends 21 and 22 are bent downwards 41, spreading the sides of the top surface 3 of the expandable section 6 and bending it in the direction 16, so that the bent curved section 55 has an angle 34. In Figure D, the upper parts 45 of both expandable sections have a distance 15 that extends in the longitudinal direction 5. When the left and right ends 21 and 22 are returned to their original state, the expandable section 6 returns to its original state, and the bent curved section 55 with an angle 34 returns to its original flat state when the storage container 10 is placed on a table or the like.

[0035] In Figure D, the bottom surface 47 is preferably bent along the fold line from the pivot 17 of fan 39 to the pivot 17 of fan 40, and at the same time, the top 67 of the fan surface of the expandable portion 6 on 39 and 40 is extended to a predetermined extension distance 15, forming the mountain shape 46 of the bent bottom surface 30 of the storage container, and the upper surface 25 of the pushed-up laminate and the opening 7 are at a distance 49 where the vertical distance 42 approaches each other.

[0036] In other words, a predetermined extension distance 15 is provided at the top 67 of the curved and extended fan surface, and the shape of the peak 46 at the position of the fan's pivot 17 on the bottom surface 47 and the top surface 25 of the laminate and the dispensing opening 7 reduces the vertical distance 42 between them. As a result, even if the volume 36 of the laminate gradually decreases, the sheet 4 on the top surface 25 of the laminate can be brought closer to the dispensing opening 7, making it easy to pick up with fingers in a timely manner. Compared to the difficult work of conventional products, the present invention eliminates the risks of work associated with conventional products because fingers do not get dirty with chemicals, or can be picked up by visual inspection, and the frequency of fingers touching the inside 35 is minimized.

[0037] The expandable portion 6 is expandable and can be an integral part of a resin molded product, or made of elastic rubber or the like, or it can be cut along perforations as desired. The distance it extends 15 returns to its original state when the bottom surface 47 is returned to its original position by 21 and 22. In other words, by grasping 21 and 22 and bending the expandable portion 6, the process from Figure C to Figure D and from Figure D to Figure C is repeated. The operation is the same even if the expandable portion 6 is provided on the short sides 8 of the left and right ends 23 and 24 instead of the front and rear long sides 39 and 40.

[0038] The storage container 10 is composed of a pair of long sides 39 and 40 extending in the longitudinal direction 5, a pair of short sides 23 and 24 extending in the transverse direction, and a bottom surface 47 connecting the pair of long sides 39 and 40 and the pair of short sides 23 and 24, with an open top surface 56 facing the bottom surface 47.

[0039] Near the center 37 of the longitudinal direction 5 of the pair of long sides 39 and 40, an extendable portion 6 of the fan's pivot 17 is formed, which allows the bottom surface 47 to be curved around the curved portion 55 near the center 37 of the bottom surface 47 in the longitudinal direction 5.

[0040] The bag body 1 includes an opening 7 for taking out the sanitary paper 11 stored in a storage container 10 formed near the center 37 of the top surface 3 of the bag body 1, and a lid for opening or closing the opening 7.

[0041] This sanitary paper packaging is characterized in that, when the volume 36 (height) of the stack decreases due to the use of sanitary paper 11, the bottom surface 47 of the storage container 10 is curved into a mountain shape 46, pushing the central part 37 of the stack 2 upward 26, thereby bringing the top surface 25 of the stack closer to the dispensing opening 7, and facilitating the dispensing of sanitary paper 11 from the dispensing opening 7 in the bag 1.

[0042] The bottom surface 47 of the storage container 11 has a curved bottom surface 47 in the central part 37 in the longitudinal direction 5, which is curved to form a mountain shape 46, and has a bend line 31 along the center line in the short direction from one of a pair of long pieces 39, 40 to the other, which are used to bring the top surface 25 of the stacked body closer to the opening 7 and facilitate the gripping of the 25.

[0043] The expandable sections 6 formed on a pair of long sides 39 and 40 of the storage container 10 have a fan shape 44 with the connection point 58 between the pair of long sides 39 and 40 and the bottom surface 47 as the pivot point 17, and the bend line 31 is formed by connecting the positions of the pivot points 17 of the pair of expandable sections 6.

[0044] The expandable portion 6 formed on the pair of long sides 39 and 40 is integrally formed with the areas of the long sides 39 and 40 other than the expandable portion 6.

[0045] The expandable portion 6 formed on the pair of long sides 39 and 40 is constructed by connecting an elastic material to the areas of the long sides 39 and 40 other than the expandable portion 6.

[0046] A sanitary paper packaging body 57 comprises a bag body 1 and a storage container 10 located inside the bag body 1 35 for storing a laminate 2 of sanitary paper 11. The storage container 57 is composed of a pair of long sides 39, 40 extending in the longitudinal direction 5, a pair of short sides 23, 24 extending in the transverse direction 8, and a bottom surface 61 connecting the pair of long sides 39, 40 and the pair of short sides 23, 24. The top surface 76 of the storage container facing the bottom surface 61 is open. Near the center 37 of the pair of long sides 39, 40 in the longitudinal direction 5, expandable portions 6 are formed on the pair of long sides 39, 40 to allow the bottom surface 61 to bend around a curved portion 55 near the center 37 of the bottom surface 61 in the longitudinal direction 5.

[0047] The bag body 1 is a sanitary paper packaging body characterized by having an opening 7 for taking out sanitary paper 11 stored in a storage container 10 formed near the center 37 of the top surface 3 of the bag body 1, and a lid 18 for opening or closing the opening 7, and by the top surface 25 of the laminated body 2, whose height gradually decreases as the sanitary paper 11 is used, the bottom surface 61 of the storage container is folded and the area near the center 37 of the laminated body 2 is pushed upward 26, thereby facilitating the removal of the sanitary paper 11 from the top surface 25 of the laminated body through the opening 7 of the bag body 1.

[0048] A second embodiment will be described.

[0049] A second embodiment is illustrated in Figures 1, G, H, I, J, K, L, M, and N.

[0050] In other words, the support member 74 on which the laminate 2 is placed is shown in Figures 1 and G, H, I, J, K, L, M, and N, and as shown in the cross-sectional view and perspective view of the plate 72 of the storage container 10, when the plate 72 in the longitudinal direction 5 is bent in the bending direction 16, the bent portion 73 along the center line 9 in the short direction of the plate 72 of the storage container 10 in the longitudinal direction 5 has a mechanism 47 that closes at a predetermined angle 63 to an angle 64 in the closing direction.

[0051] The shape of the bent portion 73 is such that the central part 37 where the 14 and 9 of the bottom portion 30 of the storage container intersect is bent from the key portion 17 along the direction of the short-side center line 9 that intersects the longitudinal center line 14 to a closing angle 64, and the tip 48 of the determined peak shape 65 with a closing angle 64 having an angle 34 of less than 180 degrees that has been bent to the specified closing angle 64 is pushed up toward the dispensing opening 7, and there is a proximity distance 49 that allows the upper surface 25 of the stacked body and the dispensing opening 7 facing it to come closer together.

[0052] The bent portion 73 of the plate body 72 has a notched region 78 formed on the plate body 72 along the center line 9 in the short direction, facing the short direction 8 of the plate body 72, and the notched region 78 has one or more holes, or recesses on one or both sides of the front or back of the plate 27 of the bottom portion 30, or a cut line, and has an angle and distance in the direction 64 that closes from a predetermined angle 63.

[0053] In Figure I, the predetermined angles 63 on both the front and back of the flat bottom 30 of the storage container change as the left end 21 and the right end 22 are bent in the direction 16 away from the center line 9 in the shorter direction. When the predetermined angle 63 on the back side of Figure J changes to an angle 64 where it closes, the predetermined angle 63 on the front side changes to an angle 66 where it opens wide, and the surface in contact with the center line 9 in the shorter direction stabilizes and pushes up the bottom surface 60 of the laminate.

[0054] In other words, the angle 63 determined near the center 37 of the left end 21 and the right end 22 is bent along the center line in the shorter direction and brought together. For example, the tip 48 of the mountain shape 46, which is formed by combining a small angle 34 with a 90-degree angle 34 consisting of 45 degrees to the left and 45 degrees to the right, does not show a large change in the approach distance 49, making it difficult to grasp the sheet 4 on the top surface 25 of the laminate.

[0055] Furthermore, the tip 48 of the mountain shape 46, which is formed by combining large angles 34, such as 75 degrees to the left and 75 degrees to the right, resulting in a 150-degree angle 34, is pushed up, and the tip 48 of the folded mountain shape 46 and the dispensing opening 7 come closer together, resulting in a large change in the approaching distance 49, making the sheet 4 on the top surface 25 of the laminate easier to grasp.

[0056] For example, in a process produced on the same production line, when comparing the height 36 of the laminated sheet 4 for a 30-sheet product specification with the height of the laminated sheet 4 for a 50-sheet product specification, the 50-sheet version needs to have a larger angle, and when folded and the angle is matched, the mountain-shaped tip 48 has a distance 49 that brings it closer to the dispensing opening 7.

[0057] The bottom surface 30 of the storage container 10 maintains its position when placed on a surface, has a rectangular shape 56 along the longitudinal center line 14, and has a mechanism 47 along the intersecting transverse center lines 9.

[0058] In addition, the laminated body 2 is placed on the storage container 10, and walls 59 that fix the laminated body 2 from movement in all directions (left and right) can be connected to the bottom surface 47 of the storage container on the front and rear sides, or the left and right sides, or on either the front and rear sides and the left and right sides.

[0059] Figure H is a perspective view of a rectangular shape with an angle 63 determined along the short-side center line on the back surface near the center 37, and Figure G is a cross-sectional view of a folded V-shape 65, where the angle 63 determined along the short-side center line 9 has an angle 64 that closes in the bending direction 16.

[0060] Figure I shows a predetermined angle 63 along the short-side centerline 9 on both the front and back surfaces of the cross-section of the bottom 30 of the storage container. Figures I and J show a perspective view in which, when folded in the bending direction 16, the bent side (back surface) has a closed angle 64, and the opposite side of the closed angle 64 has a predetermined angle 63, while the open angle 66 is flat along the short-side centerline 9. Figure J shows a closed angle 64 on the back surface and an open angle 66 on the surface of the opposite side.

[0061] Figure K is a perspective view of the back side of the cross-section of the bottom 30 of the storage container, which has a predetermined angle 63 along the short-side center line 9. Furthermore, the cross-section in the longitudinal direction 5 has corrugated walls 59 on both sides of the short-side center line 9, and corrugated walls 59 on the edges of the left and right ends 21 and 22. The walls 59 are provided arbitrarily.

[0062] The perspective view in Figure L shows that when the angle 63 determined in the bending direction 16 of Figure K is bent, it has a V-shape 65 which is determined to be an angle 64 that closes to the bent side.

[0063] Figure M is a perspective view of the bottom 30 of the storage container, showing a predetermined angle 63 along the short-side center line 9 on the back side of the cross section. Furthermore, the cross section in the longitudinal direction 5 has guide sections 75, which are walls 59, on both sides of the short-side center line 9, serving as guides to stabilize the long and short sides of the laminated body 2 made of panels or rod-shaped 67. The edges of the left and right ends 21 and 22 also have walls 59 made of panels or rod-shaped 67. The walls 59 made of 67 can be provided as desired.

[0064] Figure N is a perspective view showing a V-shape 65 that closes to the bent side at an angle 64 determined by the angle 63 determined in the bending direction 16 of Figure M.

[0065] In other words, the plate body 1 is provided with a guide portion 75 that extends upward 26 from the end 77 of the plate body 72 to guide the laminated body 2 by contacting the edge of the laminated body 2, and the guide portion 75 is provided with a wave shape 19 or wall 59 on the edge 77 of the substantially rectangular 56 side of the plate body 72, at a position away from the bending portion 73 so as not to interfere with the bending of the plate body 72, and is in contact with the laminated body 2 and stands upright for guidance, with a short-side center line 9 in between.

[0066] A sanitary paper packaging body 57 comprises a bag body 1 and a support member 74 for the laminate 2 located inside the bag body 1 35 for supporting the laminate 3 of sanitary paper 11, wherein the support member 74 comprises a plate body 72 that supports the laminate 2 from below 41 and a bending portion 73 formed near the center 37 of the longitudinal direction 5 of the plate body 72, which allows the plate body 72 to be folded along a center line 9 facing the short direction 8 of the plate body 72.

[0067] The bag body 1 is equipped with an opening 7 for taking out the sanitary paper 11 stored in a storage container 10 formed near the center 37 of the top surface 3 of the bag body 1, and a lid 18 for opening or closing the opening 7. The sanitary paper packaging is characterized in that, as the height of the laminate 2 gradually decreases with use of the sanitary paper 11, the plate 72 of the support member 74 is bent, pushing the area near the center 37 of the laminate 2 upward 26, thereby facilitating the removal of the sanitary paper 11 from the top surface 25 of the laminate through the opening 7 of the bag body 1.

[0068] A third embodiment will be described.

[0069] A bending portion 73 is formed near the center 37 in the longitudinal direction of the bottom surface 30 of the storage container 10, allowing the bottom surface 30 to be folded along a center line 9 that faces the short direction 8 of the bottom surface 30. Figures G, H, I, J, K, L, M, and N can also be provided in the same manner.

[0070] The following describes the points that are common to the first, second, and third embodiments.

[0071] The dispensing opening 7 on the surface 62 opposite the top surface 25 of the laminated stack 2 of the sanitary paper 11 contained in the storage container 10, where the height 36 of the stack gradually decreases, is located at a position where the center line 14 in the longitudinal direction and the center line 9 in the short direction of the top surface 3 of the stack intersect, with the top surface 25 and the top surface 3 facing each other.

[0072] The mechanism 47 is located at a key part 17 that reduces the vertical distance between the top surface 25 and the top surface 25 of the laminated body, which has a dispensing opening 7 on the top surface 3 and the top surface 25 of the laminated body, as the height 36 of the laminated body in the storage container 10 gradually decreases with repeated use. As the height 36 of the laminated body gradually decreases with repeated use, the vertical distance 42 between 25 and 7 increases with repeated use. The mechanism 47 is located at a key part 17 that reduces the vertical distance between the top surface 25 of the laminated body and the dispensing opening 7. When the distance between 25 and 7 is reduced, the sheet 4 on the top surface 25 of the laminated body can be easily grasped and smoothly removed from the dispensing opening 7.

[0073] The key part 17 is the position where the bottom 30 of the storage container is folded at a predetermined angle 63 in the shorter direction 8, and is located near the center 37 where 14 and 9 of the bottom 30 of the storage container intersect, and extends from 37 along the direction of the shorter center line 9 that intersects the longitudinal center line 14.

[0074] When the bottom 30 of the storage container is folded at an angle 63 along the center line 9 in the shorter direction, the distance between the tip 48 of the mountain shape 46 and the dispensing opening 7 changes to a distance 49 in which they come closer together, and the bottom 30 of the storage container having a laminate 2 in which the height 36 of the laminate gradually decreases is folded along the center line 9 in the shorter direction, and the mountain shape 46 having an angle 34, the sheet 4 on the top surface 25 of the laminate, and the dispensing opening 7 which can be easily grasped and removed come closer together and are pushed up.

[0075] The distance 49 between the top surface 25 of the laminate being pushed up and the dispensing opening 7 is such that the top surface 25 of the laminate, which is specified in the product specifications for each OEM product and which can be used when the dispensing opening 7 is opened, is visible, and the sheets 4 on the top surface 25 of the laminate can be easily grasped and pulled up with at least the fingertips.

[0076] The embodiment has a mechanism 47 in which the bottom 30 of the storage container bends along the center line 9 in the shorter direction, thereby simultaneously pushing up the laminated body 2.

[0077] The storage container 10 maintains a state in which the laminate 2 is placed on the storage container 10 with the bottom surface 60 of the laminate facing the bottom surface 61 of the storage container, and all embodiments have a mechanism 47.

[0078] The bottom surface 60 of the laminate and the bottom surface 47 of the storage container have flat surfaces on which the laminate can be placed. Furthermore, the dispensing opening 7, which faces the top surface 25 of the laminate during use, has a push-up mechanism 47 on the bottom surface 30 that brings the top surface 25 of the laminate and the dispensing opening 7 closer together when the sheet 4 is picked up and pulled out from the dispensing opening 7.

[0079] The corrugated shape 19, or flat plate 67, or the bottom 30 of the storage container 10, or a pair of long sides 39, 40, or a pair of short sides 23, 24 of the storage container protect the laminate 2. The sides 23, 24, 39, 40, or the wall 59, or the bottom 30 of the storage container may be provided with holes 50 through which the liquid medicine filled in can pass.

[0080] Conventional bags 1 are stacked in a container of a certain height, but the height 36 of the stacked material has decreased, making the process of picking up sheets 4 troublesome and difficult. For example, especially when fingertips and toenails are long and the hands are in a décolleté position, relying on the sense of touch with the fingertips to find the sheets 4 can result in fingers getting covered in the liquid, or dirt from the fingers mixing with the remaining liquid, or accidentally picking up multiple sheets.

[0081] The enclosed laminate 2 is a laminate 2 in which each sheet 4 is folded in a pop-up manner and stacked, or a laminate 2 in which each sheet is folded and stacked, or a sanitary paper 11 in which cut cotton or cotton balls are arranged (hereinafter referred to as "laminated") 2, and the longitudinal center line 14 of the laminate 2 is located in line with the center line 14 of the top surface 3 and the center line 14 of the storage container 10.

[0082] Examples of materials for the storage container include flexible resin, natural materials, coated cardboard, paper, resin, wood, metal, rubber, or a combination of any of these. The choice is arbitrary, and suitability should be verified.

[0083] The material of the container 19 is a general-purpose material made of resin, such as polyethylene terephthalate (PET) or polyethylene (PE), or polypropylene (PP), or metal, for the wet laminate 2. Any material that has elasticity and can stretch in the direction 16 in which the expandable part 6 bends and return to its original shape is acceptable. It is also optional to provide holes 50 through which the wet filling liquid passes through the bottom surface 61 or the sides 23, 24, 39, and 40.

[0084] The dry laminate 2 may be made of the same resin used for the wet laminate 2, but it may also be made of cardboard with an expandable section 6 formed on it, at the discretion of the planner. Sustainable recycled paper that can form a bellows shape 43 or a fan shape 44 is preferred. The choice is at the discretion of the planner based on material cost or product specifications.

[0085] The molded product of the storage container 10 is obtained by punching out a three-dimensional shape from a resin sheet while applying heat, by a 3D molding method, by forming a PET resin sheet or the like using a compressed air (heat, vacuum, and compressed air) method, or by melting LLDPE or the like or recycled materials with heat and molding by injection or the like.

[0086] The molded products vary depending on the product, but for example, the outer dimensions of wet wipes are 150mm x 200mm wide, and the outer dimensions of face masks are 200mm x 200mm wide. The outer dimensions and manufacturing process of the laminated products 2, which are folded in a specific way, vary, but the approximate dimensions of the storage container 10 for 30 laminated products 2 are roughly 100mm (length) x 200mm (width) x 40mm (height). Furthermore, the approximate dimensions of the storage container 10 for about 20 laminated products, which are compact storage containers 10 that are folded in half horizontally and referred to as handy type, are roughly 80mm (length) x 120mm (width) x 30mm (height).

[0087] The sanitary paper 11 can be wet or dry and has a wide range of uses, the state of the laminate 2 is arbitrary, and the sheet 4 can be tissue paper, a nonwoven fabric sheet, a face mask sheet, a wet wipe, a cosmetic sheet, a biocellulose sheet, a gel sheet containing a gel agent, or a sponge sheet, etc.

[0088] The chemical solution impregnated into sheet 4 has the effect of complying with both the Pharmaceuticals and Medical Devices Act and general merchandise regulations. For example, the liquid agent used to impregnate sheet 4, or the powder or paste used in a poultices, etc.

[0089] Cosmetic sheets (including quasi-drugs compliant with the Pharmaceuticals and Medical Devices Act) 4 are made from materials such as nonwoven fabric sheets, biocellulose, sponge sheets, and pile fabrics, and are pharmaceutical materials that contain medicinal solutions for use on the human body. They are impregnated products related to cosmetic use, such as cosmetic face mask sheets, neck care sheets, eye area sheets, makeup remover sheets, facial cleansing sheets, moisturizing sheets for hands or body, and sheets that protect hair or scalp.

[0090] Medical (Pharmaceuticals and Medical Devices Act compliant) sheet 4 is a pharmaceutical product made from a nonwoven fabric sheet, intended for use in patient medical care, and containing a medicinal solution. Examples include gauze, cotton balls, sanitary napkins, cotton pads, cotton swabs, sponges, etc., which are sterilized using ethylene oxide gas, gamma irradiation, autoclaving, etc., and then impregnated with a liquid such as alcohol or povidone-iodine at the time of use, or sealed in a pharmaceutical-compliant container that has already been impregnated. Cosmetic sheets may be used in medical sheets after verification.

[0091] Sheets 4 for general use (excluding those compliant with the Pharmaceuticals and Medical Devices Act) are products impregnated with cleaning agents, such as cleaning sheets, furniture wiping sheets, car seats, microwave-safe sheets, and cooking bags. For use with animals, it is recommended to comply with the laws of the Ministry of Agriculture, Forestry and Fisheries.

[0092] The basis weight of sheet 4 can be selected from, for example, 10 (g / mm²) to 200 (g / mm²) of nonwoven fabric sheets, and the manufacturing method and basis weight of the nonwoven fabric sheet are optional. A nonwoven fabric sheet made by the spunlace method, which is strong in the longitudinal direction and stretchable in the transverse direction, is preferable, but the selection is optional.

[0093] Nonwoven fabric sheets made from natural materials are composed of natural fibers such as cotton, Tencel, and lyocell. Furthermore, they may also be made from natural fibers that have been treated with charcoal or a coating.

[0094] Nonwoven fabric sheets, made from synthetic fibers, consist of rayon, polyester phthalate, polypropylene, polyethylene, and other synthetic fibers. Sometimes, they are used in combination with natural fibers.

[0095] The materials and film sheets for bag 1 are composed of paper, polyethylene terephthalate (PET), polyethylene (LLDPE), OPP, CPP, aluminum foil, metal vapor deposition, paper, etc., and heat is applied using high frequency or a hot plate to form bag 1.

[0096] The storage container 10 is made of one of the following: coated cardboard, paper, resin, wood, or metal. The shape of the storage container 10 may have a bottom surface 47 with sides 23, 24, 39, and 40, and the bottom surface 47 or sides 23, 24, 39, and 40 may have holes 50 through which the filling liquid passes. The bottom surface 30 may be a plate 72. The sanitary paper 11 has a laminate 2 in a dry or wet state.

[0097] While a wet sanitary paper packaging 57 requires a resin film 32 with high barrier function, a dry sanitary paper packaging 57 can be any resin film 32 with no particular barrier properties. For example, a packaging containing a laminate of tissue paper may have a perforated opening that can be torn off by pressing with a fingertip along the longitudinal center line 14 sandwiched between side A 12 and side B 13 on the longitudinal direction 5 of the top surface 3, and the same mechanism 47 may be provided. The presence or absence of a lid 18 is optional.

[0098] The applicant's previously filed Japanese Patent Application No. 2025-171936 describes a packaging material comprising a bag 1 made of resin film 56 that encloses a laminate 2 made of laminated sheets 4 of sanitary paper 11, with perforated cut lines 30 along the longitudinal direction 5 of the top surface 3 to provide an opening 42 that can be torn open with fingers, and a plate 18 connected to the inside 20 of the top surface 3 of the bag 1. Adding the mechanism 47 of the present application to this packaging material further increases the variety of packaging materials that can be easily removed.

[0099] The bag body 1 has perforated cut lines 30 along the longitudinal center line 14 of the top surface 3 made of resin film 56, and has a longitudinal opening 42 that can be torn open with a finger.

[0100] The plate body 18 has an opening 7 with finger hole areas 31 on the left and right sides along the longitudinal center line 14, and has guide parts 52 that are added from the left and right finger hole areas 31 in the direction of left and right connecting parts 33 and 35, and has left and right guide shapes 53 and 54 through which the left and right ends of the sheet 4 pass when pulled out.

[0101] The positions formed on the top surface 3 to the bottom surface 51 of the storage container 10 are such that the center line 14 in the longitudinal direction 5 of the top surface 3 of the bag body 1, the center line 14 in the longitudinal direction 5 of the plate body facing the top surface 25 of the laminate body, and the center line 14 in the longitudinal direction 5 of the laminate body 2 on the inside 20 of the top surface 3 are aligned in the same direction, and from top to bottom they are positioned in the order of top surface 3, plate body, and laminate body 2.

[0102] The bag body 1 has a configuration in which a plate is placed on the upper surface 25 of the laminate inside 20, and the sheet 4 on the upper surface 25 of the laminate is passed through an opening 7 in the plate and removed from the opening on the top surface 3. [Explanation of symbols]
