Abstract
Description
[Technical Field]
[0001] The present invention relates to a sanitary sheet laminate in which a plurality of sanitary sheets are folded like tissues and stored in a container or the like. [Background technology]
[0002] Conventionally, when a plurality of wet tissues impregnated with a medicinal solution are stored in a container, the wet tissues are folded in thirds and stacked one on top of the other, and the user takes out the stacked wet tissues in order from the top through an outlet formed in the container. Furthermore, to make it easier for users to take out the wet tissues stacked in this way, the topmost wet tissue is arranged so that a part of it protrudes from the outlet. This is called the pop-up system.
[0003] That is, in the pop-up system, when one wet tissue is taken out from the outlet, a part of the wet tissue arranged below it protrudes from the outlet. To enable such a pop-up system, it is necessary for the folded wet tissues contained in a container or the like to be arranged so that a portion of each folded wet tissue overlaps a portion of the other wet tissues. Various folding methods for arranging wet tissues in this way have been proposed in the past (for example, Patent Document 1).
[0004] In the pop-up method, when a first wet tissue is discharged from the outlet, a portion of a second wet tissue placed below it is simultaneously discharged from the outlet while still attached (i.e., glued) to the first wet tissue. If the portion of the second wet tissue that was attached to the first wet tissue then separates from the first wet tissue, a portion of the second wet tissue protrudes from the outlet, creating a "pop-up" state. However, there are cases where the first and second wet tissues are so tightly attached to each other that the second wet tissue does not separate from the first wet tissue and is discharged as is, resulting in a phenomenon known as "cheating."
[0005] While assuming a pop-up system, there is room for improvement in the various folding methods for sanitary sheets that have been proposed so far in terms of preventing such "cheating." [Prior art documents] [Patent documents]
[0006] [Patent Document 1] Patent No. 5651315 Summary of the Invention [Problem to be solved by the invention]
[0007] The present invention has been made in consideration of the above circumstances, and aims to provide a sanitary sheet laminate that can prevent the occurrence of "mistakes" when sanitary sheets that are folded so that they partially overlap each other are removed from the removal opening, whereby the next sanitary sheet is also removed from the removal opening. [Means for solving the problem]
[0008] The problem is a sanitary sheet laminate in which a plurality of sanitary sheets are folded and stored inside a container having a take-out opening, the sanitary sheets can be sequentially taken out from the take-out opening, and have a structure in which a first region, a second region, a third region, and a fourth region are arranged in this order, the second region is arranged on the upper side of the container in which the take-out opening is formed, the first region is arranged below the second region by folding the sanitary sheet, the third region is arranged below the second region by folding the sanitary sheet, the fourth region is arranged between the second region and the third region by folding the sanitary sheet, and This problem is solved by the sanitary sheet laminate of the present invention, characterized in that the folded portion between the third region and the fourth region faces the folded portion between the third and fourth regions of the second sanitary sheet that is to be removed from the removal opening after the first sanitary sheet, via the center of the width of the container, the surface of the third region of the first sanitary sheet faces the surface of the first region of the second sanitary sheet, the surface of the fourth region of the first sanitary sheet faces the surface of the second region of the second sanitary sheet, and the end of the fourth region of the first sanitary sheet faces but is spaced apart from the end of the first region of the second sanitary sheet.
[0009] The sanitary sheet laminate of the present invention forms a gap (space) between the edge of the fourth region of the first sanitary sheet and the edge of the first region of the second sanitary sheet, which reduces the contact area between the first and second sanitary sheets and reduces friction between them compared to when the edge of the fourth region of the first sanitary sheet is in contact with the edge of the first region of the second sanitary sheet, thereby further reducing the occurrence of "slippage."
[0010] In the sanitary sheet laminate of the present invention, it is preferable that the folded portion between the third region and the fourth region of the second sanitary sheet faces, via the central portion, the folded portion between the third region and the fourth region of the third sanitary sheet that is to be removed from the removal opening after the second sanitary sheet, the surface of the third region of the second sanitary sheet faces the surface of the first region of the third sanitary sheet, the surface of the fourth region of the second sanitary sheet faces the surface of the second region of the third sanitary sheet, and the edge of the fourth region of the second sanitary sheet faces, but is spaced apart from, the edge of the first region of the third sanitary sheet.
[0011] The sanitary sheet laminate of the present invention forms a gap (space) between the edge of the fourth region of the second sanitary sheet and the edge of the first region of the third sanitary sheet, which reduces the contact area between the second and third sanitary sheets and reduces friction between them compared to when the edge of the fourth region of the second sanitary sheet is in contact with the edge of the first region of the third sanitary sheet, thereby further reducing the occurrence of "slippage."
[0012] The sanitary sheet laminate of the present invention is preferably characterized in that a space is formed between the end of the first region of the first sanitary sheet and the folded portion between the second region and the third region of the first sanitary sheet.
[0013] The sanitary sheet laminate of the present invention reduces the contact area between the first and second sanitary sheets and reduces the friction between them, compared to when there is no space between the edge of the first region of the first sanitary sheet and the folded portion between the second and third regions of the first sanitary sheet, thereby further reducing the occurrence of "slippage." [Effects of the Invention]
[0014] According to the present invention, a sanitary sheet laminate can be provided that can prevent the occurrence of "slip-up" when sanitary sheets that are folded so that they partially overlap each other are removed from the removal opening, whereby the next sanitary sheet is also removed from the removal opening.

DETAILED DESCRIPTION OF THE INVENTION
[0016] Preferred embodiments of the present invention will now be described in detail with reference to the drawings. The embodiments described below are preferred examples of the present invention, and therefore various technically preferable limitations are applied thereto, but the scope of the present invention is not limited to these aspects unless otherwise specified in the following description to the effect that the present invention is particularly limited. Furthermore, in each drawing, similar components are designated by the same reference numerals, and detailed descriptions thereof will be omitted as appropriate.
[0017] FIG. 1 is a plan view showing a sanitary sheet laminate according to an embodiment of the present invention. FIG. 2 is a schematic diagram showing the first and third sanitary sheets of this embodiment. FIG. 3 is a schematic diagram showing a second sanitary sheet according to the present embodiment. For ease of explanation, FIG. 1 shows a state in which the sanitary sheet laminate 2 of this embodiment is contained in a container 3. 2(a) and 3(a) are schematic diagrams showing the state of the sanitary sheet before it is folded and the state of the sanitary sheet after it is unfolded, while Fig. 2(b) and 3(b) are schematic diagrams showing the state of the sanitary sheet after it has been folded.
[0018] The sanitary sheet laminate 2 according to this embodiment comprises a plurality of folded sanitary sheets housed in a container 3 as shown in FIG. 1. The container 3 according to this embodiment is an example of the "container" of the present invention. Examples of the sanitary sheets in the sanitary sheet laminate 2 include wet tissues impregnated with a medicinal solution. The container 3 shown in FIG. 1 has an outlet 31 for removing the sanitary sheets of the sanitary sheet laminate 2. As shown in FIG. 1, the outlet 31 is formed in the center of the top of the container 3. The sanitary sheet laminate 2 according to this embodiment employs a pop-up system. Therefore, the plurality of sanitary sheets can be removed sequentially from the outlet 31 of the container 3.
[0019] In the sanitary sheet laminate 2 shown in Fig. 1, a first sanitary sheet 4, a second sanitary sheet 5, and a third sanitary sheet 6 are stacked in this order from top to bottom inside the container 3. The second sanitary sheet 5 is the sanitary sheet to be removed from the removal opening 31 after the first sanitary sheet 4. The third sanitary sheet 6 is the sanitary sheet to be removed from the removal opening 31 after the second sanitary sheet 5.
[0020] As shown in Figure 2(a), the first sanitary sheet 4 has a structure in which a first region 41, a second region 42, a third region 43, and a fourth region 44 are arranged in this order. Similarly to the first sanitary sheet 4, the third sanitary sheet 6 has a structure in which a first region 61, a second region 62, a third region 63, and a fourth region 64 are arranged in this order. Because the structure of the third sanitary sheet 6 is the same as that of the first sanitary sheet 4, Figures 2(a) and 2(b) will mainly use the first sanitary sheet 4 as an example to explain the first sanitary sheet 4 and the third sanitary sheet 6.
[0021] As shown in Figures 1 and 2(b), the second region 42 is located on the upper side of the container 3 where the dispensing opening 31 is formed. The first region 41 is located below the second region 42 by folding the first sanitary sheet 4 at a first folding portion 45. The first folding portion 45 is a folding portion between the first region 41 and the second region 42. The third region 43 is located below the second region 42 by folding the first sanitary sheet 4 at a second folding portion 46. The second folding portion 46 is a folding portion between the second region 42 and the third region 43. The fourth region 44 is located between the second region 42 and the third region 43 by folding the first sanitary sheet 4 at a third folding portion 47. The third folding portion 47 is a folding portion between the third region 43 and the fourth region 44.
[0022] The first folded portion 45 and the second folded portion 46 are arranged on the outside inside the container 3, i.e., on the side away from the central portion 32 of the container 3. The first folded portion 45 is arranged on one outside inside the container 3. The second folded portion 46 is arranged on the other outside inside the container 3. The third folded portion 47 is arranged on the inside inside the container 3, i.e., on the side of the central portion 32 of the container 3. The arrangement of each folded portion is similar for the third sanitary sheet 6. That is, the first folded portion 65 is arranged on one outside inside the container 3. The second folded portion 66 is arranged on the other outside inside the container 3. The third folded portion 67 is arranged on the inside inside the container 3, i.e., on the side of the central portion 32 of the container 3.
[0023] 2(a), in the longitudinal direction Y of the first sanitary sheet 4 (corresponding to the folding direction perpendicular to the fold lines of the sanitary sheet), the length L11 of the first region 41 is equal to the length L14 of the fourth region 44 and is shorter than the length L12 of the second region 42 and the length L13 of the third region 43. The ratio (L11 / L) of the length L11 of the first region 41 to the length L of the first sanitary sheet 4 in the longitudinal direction Y and the ratio (L14 / L) of the length L14 of the fourth region 44 to the length L of the first sanitary sheet 4 in the longitudinal direction Y are each, for example, approximately 10%.
[0024] In the longitudinal direction Y of the first sanitary sheet 4, the length L12 of the second region 42 is longer than the length L11 of the first region 41, the length L13 of the third region 43, and the length L14 of the fourth region 44. The ratio (L12 / L) of the length L12 of the second region 42 to the length L of the first sanitary sheet 4 in the longitudinal direction Y is, for example, approximately 55%.
[0025] In the longitudinal direction Y of the first sanitary sheet 4, the length L13 of the third region 43 is longer than the length L11 of the first region 41 and the length L14 of the fourth region 44, but shorter than the length L12 of the second region 42. The ratio (L13 / L) of the length L13 of the third region 43 to the length L of the first sanitary sheet 4 in the longitudinal direction Y is, for example, about 25%.
[0026] In the longitudinal direction Y of the first sanitary sheet 4, the length L11 of the first region 41, the length L12 of the second region 42, the length L13 of the third region 43, and the length L14 of the fourth region 44 satisfy the above-mentioned relationship. Therefore, the area S11 of the first region 41 is equal to the area S14 of the fourth region 44 and is smaller than the area S12 of the second region 42 and the area S13 of the third region 43. The area S12 of the second region 42 is larger than the area S11 of the first region 41, the area S13 of the third region 43, and the area S14 of the fourth region 44. The area S13 of the third region 43 is larger than the area S11 of the first region 41 and the area S14 of the fourth region 44, and is smaller than the area S12 of the second region 42.
[0027] As shown in FIG. 3(a), the second sanitary sheet 5 has a structure in which a first region 51, a second region 52, a third region 53, and a fourth region 54 are arranged in this order.
[0028] As shown in Figures 1 and 3(b), the second region 52 is located on the upper side of the container 3 where the dispensing opening 31 is formed. The first region 51 is located below the second region 52 by folding the second sanitary sheet 5 at a first folding portion 55. The first folding portion 55 is a folding portion between the first region 51 and the second region 52. The third region 53 is located below the second region 52 by folding the second sanitary sheet 5 at a second folding portion 56. The second folding portion 56 is a folding portion between the second region 52 and the third region 53. The fourth region 54 is located between the second region 52 and the third region 53 by folding the second sanitary sheet 5 at a third folding portion 57. The third folding portion 57 is a folding portion between the third region 53 and the fourth region 54.
[0029] The first folded portion 55 and the second folded portion 56 are arranged on the outside of the container 3, i.e., on the side away from the central portion 32 of the container 3. The first folded portion 55 is arranged on the outside of the other of the container 3. That is, as shown in FIG. 1, the first folded portion 55 of the second sanitary sheet 5 is arranged on the same side of the container 3 as the second folded portion 46 of the first sanitary sheet 4. The second folded portion 56 is arranged on the outside of one of the container 3. That is, as shown in FIG. 1, the second folded portion 56 of the second sanitary sheet 5 is arranged on the same side of the container 3 as the first folded portion 45 of the first sanitary sheet 4.
[0030] The third folded portion 57 is disposed on the inner side of the container 3, i.e., on the side of the central portion 32 of the container 3. Therefore, the third folded portion 57 of the second sanitary sheet 5 faces each of the third folded portion 47 of the first sanitary sheet 4 and the third folded portion 67 of the third sanitary sheet 6 across the central portion 32 in the width direction of the container 3. In other words, the third folded portion 57 of the second sanitary sheet 5 faces each of the third folded portion 47 of the first sanitary sheet 4 and the third folded portion 67 of the third sanitary sheet 6 without overlapping them.
[0031] Here, in this specification, "opposite" does not only include a state in which multiple locations or parts face each other on approximately the same plane, but also a state in which multiple locations or parts face each other on different planes (for example, planes that are shifted in the vertical direction) or at different positions.
[0032] 3(a), in the longitudinal direction Y of the second sanitary sheet 5 (corresponding to the folding direction perpendicular to the fold lines of the sanitary sheet), the length L21 of the first region 51 is equal to the length L24 of the fourth region 54 and is shorter than the length L22 of the second region 52 and the length L23 of the third region 53. The ratio (L21 / L) of the length L21 of the first region 51 to the length L of the second sanitary sheet 5 in the longitudinal direction Y and the ratio (L24 / L) of the length L24 of the fourth region 54 to the length L of the second sanitary sheet 5 are each, for example, about 10%.
[0033] In the longitudinal direction Y of the second sanitary sheet 5, the length L22 of the second region 52 is longer than the length L21 of the first region 51, the length L23 of the third region 53, and the length L24 of the fourth region 54. The ratio (L22 / L) of the length L22 of the second region 52 to the length L of the second sanitary sheet 5 in the longitudinal direction Y is, for example, approximately 55%.
[0034] In the longitudinal direction Y of the second sanitary sheet 5, the length L23 of the third region 53 is longer than the length L21 of the first region 51 and the length L24 of the fourth region 54, but shorter than the length L22 of the second region 52. The ratio (L23 / L) of the length L23 of the third region 53 to the length L of the second sanitary sheet 5 in the longitudinal direction Y is, for example, about 25%.
[0035] In the longitudinal direction Y of the second sanitary sheet 5, the length L21 of the first region 51, the length L22 of the second region 52, the length L23 of the third region 53, and the length L24 of the fourth region 54 satisfy the above-mentioned relationship. Therefore, the area S21 of the first region 51 is equal to the area S24 of the fourth region 54 and is smaller than the area S22 of the second region 52 and the area S23 of the third region 53. The area S22 of the second region 52 is larger than the area S21 of the first region 51, the area S23 of the third region 53, and the area S24 of the fourth region 54. The area S23 of the third region 53 is larger than the area S21 of the first region 51 and the area S24 of the fourth region 54, but smaller than the area S22 of the second region 52.
[0036] 1 , the surface 431 of the third region 43 of the first sanitary sheet 4 faces the surface 511 of the first region 51 of the second sanitary sheet 5. The surface 431 of the third region 43 of the first sanitary sheet 4 corresponds to the inner surface of the third region 43 when the first sanitary sheet 4 is folded at the second folding portion 46 and the third folding portion 47. The surface 511 of the first region 51 of the second sanitary sheet 5 corresponds to the outer surface of the first region 51 when the second sanitary sheet 5 is folded at the first folding portion 55.
[0037] 1, the surface 441 of the fourth region 44 of the first sanitary sheet 4 faces the surface 521 of the second region 52 of the second sanitary sheet 5. The surface 441 of the fourth region 44 of the first sanitary sheet 4 corresponds to the outer surface of the fourth region 44 when the first sanitary sheet 4 is folded at the third folding portion 47. The surface 521 of the second region 52 of the second sanitary sheet 5 corresponds to the inner surface of the second region 52 when the second sanitary sheet 5 is folded at the first folding portion 55 and the second folding portion 56.
[0038] 1 , the surface 531 of the third region 53 of the second sanitary sheet 5 faces the surface 611 of the first region 61 of the third sanitary sheet 6. The surface 531 of the third region 53 of the second sanitary sheet 5 corresponds to the inner surface of the third region 53 when the second sanitary sheet 5 is folded at the second folding portion 56 and the third folding portion 57. The surface 611 of the first region 61 of the third sanitary sheet 6 corresponds to the outer surface of the first region 61 when the third sanitary sheet 6 is folded at the first folding portion 65.
[0039] 1, the surface 541 of the fourth region 54 of the second sanitary sheet 5 faces the surface 621 of the second region 62 of the third sanitary sheet 6. The surface 541 of the fourth region 54 of the second sanitary sheet 5 corresponds to the outer surface of the fourth region 54 when the second sanitary sheet 5 is folded at the third folding portion 57. The surface 621 of the second region 62 of the third sanitary sheet 6 corresponds to the inner surface of the second region 62 when the third sanitary sheet 6 is folded at the first folding portion 65 and the second folding portion 66.
[0040] Furthermore, the area S21 of the first region 51 of the second sanitary sheet 5 and the area S14 of the fourth region 44 of the first sanitary sheet 4 are each smaller than the area S13 of the third region 43 of the first sanitary sheet 4.
[0041] 1, the edge 442 of the fourth region 44 of the first sanitary sheet 4 faces the edge 512 of the first region 51 of the second sanitary sheet 5 while being spaced apart from it. Therefore, a gap (space) 71 can be formed between the edge 442 of the fourth region 44 of the first sanitary sheet 4 and the edge 512 of the first region 51 of the second sanitary sheet 5. In other words, a non-contact portion of the first sanitary sheet 4 and the second sanitary sheet 5 can be provided between the edge 442 of the fourth region 44 of the first sanitary sheet 4 and the edge 512 of the first region 51 of the second sanitary sheet 5, where the surfaces 431 and 521 directly face each other but do not come into contact with each other. Therefore, compared to when the edge 442 of the fourth region 44 of the first sanitary sheet 4 contacts the edge 512 of the first region 51 of the second sanitary sheet 5 and no space 71 is formed, the contact area between the first sanitary sheet 4 and the second sanitary sheet 5 can be reduced, and the frictional force between the first sanitary sheet 4 and the second sanitary sheet 5 can be reduced. This further reduces the occurrence of "slippage."
[0042] 1 , a gap (space) 72 is formed between the end 412 of the first region 41 of the first sanitary sheet 4 and the second folded portion 46 of the first sanitary sheet 4. In other words, a non-contact portion between the first sanitary sheet 4 and the second sanitary sheet 5 can be provided between the end 412 of the first region 41 of the first sanitary sheet 4 and the second folded portion 46 of the first sanitary sheet 4, where the surface 421 of the second region 42 of the first sanitary sheet 4 and the surface 522 of the second region 52 of the second sanitary sheet 5 directly face each other. The surface 421 of the second region 42 of the first sanitary sheet 4 corresponds to the inner surface of the second region 42 when the first sanitary sheet 4 is folded at the first folded portion 45 and the second folded portion 46. The surface 522 of the second region 52 of the second sanitary sheet 5 corresponds to the outer surface of the second region 52 when the second sanitary sheet 5 is folded at the first folding portion 55 and the second folding portion 56. Therefore, compared to when no space 72 is formed between the end 412 of the first region 41 of the first sanitary sheet 4 and the second folding portion 46 of the first sanitary sheet 4, the contact area between the first sanitary sheet 4 and the second sanitary sheet 5 can be reduced, thereby reducing the friction between the first sanitary sheet 4 and the second sanitary sheet 5. This further reduces the occurrence of "slip."
[0043] 1 , the edge 542 of the fourth region 54 of the second sanitary sheet 5 faces but is spaced apart from the edge 612 of the first region 61 of the third sanitary sheet 6. Therefore, a gap (space) 73 can be formed between the edge 542 of the fourth region 54 of the second sanitary sheet 5 and the edge 612 of the first region 61 of the third sanitary sheet 6. In other words, a non-contact portion of the second sanitary sheet 5 and the third sanitary sheet 6 can be provided between the edge 542 of the fourth region 54 of the second sanitary sheet 5 and the edge 612 of the first region 61 of the third sanitary sheet 6, where the surfaces 531 and 621 directly face each other but do not come into contact with each other. Therefore, compared to when the edge 542 of the fourth region 54 of the second sanitary sheet 5 contacts the edge 612 of the first region 61 of the third sanitary sheet 6 and no space 73 is formed, the contact area between the second sanitary sheet 5 and the third sanitary sheet 6 can be reduced, and the frictional force between the second sanitary sheet 5 and the third sanitary sheet 6 can be reduced. This further reduces the occurrence of "slippage."
[0044] In addition, the total area (area S21 + area S14) of the area S21 of the first region 51 of the second sanitary sheet 5 and the area S14 of the fourth region 44 of the first sanitary sheet 4 is smaller than the area S13 of the third region 43 of the first sanitary sheet 4.
[0045] Next, the movement of the sanitary sheet of this embodiment when it is taken out from the outlet 31 will be described with reference to the drawings. 4 to 7 are schematic diagrams illustrating the movement of the sanitary sheet when it is taken out from the outlet of the sanitary sheet of this embodiment. 4 to 7, the movement of the sanitary sheet will be explained using the sanitary sheet laminate 2 according to this embodiment as an example.
[0046] 4 (a state in which the first sanitary sheet 4 is contained in the container 3), when the first sanitary sheet 4 is pulled upward, the frictional force between the first sanitary sheet 4 and the second sanitary sheet 5 is reduced by the space 72, so the second region 42 of the first sanitary sheet 4 easily separates from the second region 52 of the second sanitary sheet 5, as shown in FIG. 5. Furthermore, since the surface 431 of the third region 43 of the first sanitary sheet 4 faces and contacts the surface 511 of the first region 51 of the second sanitary sheet 5, the first region 51 of the second sanitary sheet 5 is pulled upward together with the third region 43 of the first sanitary sheet 4, with the surface 511 adhering to the surface 431.
[0047] 6, the surface 441 of the fourth region 44 of the first sanitary sheet 4 faces and contacts the surface 521 of the second region 52 of the second sanitary sheet 5, so that the first region 51 and the second region 52 of the second sanitary sheet 5 are pulled upward together with the third region 43 and the fourth region 44 of the first sanitary sheet 4, with the surface 521 adhering to the surface 441. At this time, the space 71 formed between the first sanitary sheet 4 and the second sanitary sheet 5 is also pulled upward.
[0048] Subsequently, when the first sanitary sheet 4 is pulled further upward, the frictional force between the first sanitary sheet 4 and the second sanitary sheet 5 is reduced by the space 71, so that the second sanitary sheet 5 easily separates from the first sanitary sheet 4 due to resistance from, for example, the edge of the outlet 31 of the container 3, as shown in Figure 7. This allows the second sanitary sheet 5 to be in a "pop-up" state, while preventing "slip-up" from occurring, as shown in Figure 7.
[0049] Next, when the second sanitary sheet 5 is pulled upward, the movement of the second sanitary sheet 5 and the third sanitary sheet 6 is similar to the movement of the first sanitary sheet 4 and the second sanitary sheet 5 described above when the first sanitary sheet 4 is pulled upward. That is, because the frictional force between the second sanitary sheet 5 and the third sanitary sheet 6 is reduced by the space 73, the third sanitary sheet 6 easily separates from the second sanitary sheet 5 due to resistance from, for example, the edge of the outlet 31 of the container 3. This allows the third sanitary sheet 6 to be in a "pop-up" state while preventing slippage.
[0050] The above describes the embodiments of the present invention.
