Summary of the Invention

Problems to be Solved by the Invention

[0004] When using the sheets, in order to take out the sheets through the outlet, if the sheets get caught on the outlet or the sheets do not separate smoothly from each other, the entire sheet container may lift up when taking out the sheets, making it difficult to take out the sheets smoothly. In particular, as the remaining number of sheets in the storage space decreases with the use of the sheets, the gravity of the entire sheet container becomes lighter, making it easier for the entire sheet container to lift up when taking out the sheets and difficult to take out the sheets smoothly.

[0005] The present invention has been made in view of the above problems, and an object thereof is to provide a sheet container that suppresses the entire sheet container from lifting up when taking out the sheets and makes it easy to take out the sheets smoothly.

Means for Solving the Problems

[0006] The sheet container according to one aspect has a storage space for storing a collection of a plurality of sheets, and an outlet for the sheets stored in the storage space. In a state where the number of sheets in the collection is 15 sheets or less, the gravity of the sheet container storing the collection is higher than the tensile force when taking out the sheets from the outlet.

[0007] The sheet container according to another aspect has a storage space for storing a collection of a plurality of sheets, and an outlet for the sheets stored in the storage space. The sheet container has a suppressing means for suppressing the sheet container from lifting from the installation surface on which the sheet container is installed.

Modes for Carrying Out the Invention

[0009] (1) Outline of Embodiment At least the following matters become clear from the description of this specification and the attached drawings. The invention according to Aspect 1 is a sheet container having a storage space for storing a collection of a plurality of sheets and an outlet for the sheets stored in the storage space. In a state where the number of sheets in the collection is 15 sheets or less, the gravity of the sheet container containing the collection is higher than the tensile force when taking out the sheets from the outlet. According to this aspect, in this small number state, since the gravity of the sheet container is higher than the tensile force when taking out the sheets from the outlet, it is possible to suppress the sheet container from rising due to the gravity of the sheet container, and the sheets can be taken out smoothly.

[0010] According to a preferred aspect, the invention according to Aspect 2 may have the following features in the invention according to Aspect 1. The average value of the tensile force in the small number state is 3.0 N or less. Since the tensile force is 3.0 N or less and is relatively low, the user can easily pull out the sheets without applying a large force. Since the sheets can be pulled out without applying a large force, excessive force is not applied when pulling out the sheets, and the sheets can be pulled in the intended direction, and the lifting of the sheet container during pulling can be further suppressed.

[0011] According to a preferred aspect, the invention according to Aspect 3 may have the following features in the invention according to Aspect 1 or Aspect 2. The sheet container is configured to store the collection packaged by a packaging body. The outlet is arranged to overlap at least a part of a packaging opening formed in the packaging body. The sheets are configured to be taken out from the sheet container through the packaging opening and the outlet. In the small number state, the tensile force when taking out the sheets of the collection stored in the sheet container from the outlet is lower than the tensile force when taking out the sheets of the collection not stored in the sheet container from the packaging opening. According to this aspect, by storing in the sheet container, compared with the case of using the sheets as a single collection, the lifting of the sheet container during pulling can be further suppressed.

[0012] The invention according to Aspect 4 is a sheet container having an accommodation space for accommodating a plurality of sheets and an outlet for the sheets accommodated in the accommodation space. The sheet container has a suppressing means for suppressing the sheet container from rising from the installation surface on which the sheet container is installed. According to this aspect, the suppressing means suppresses the sheet container from rising, and the sheets can be taken out smoothly.

[0013] According to a preferred aspect, the invention according to Aspect 5 may have the following features in the invention according to Aspect 4. The suppressing means is a joining means for detachably joining the sheet container to the installation surface. In a state where the number of sheets in the aggregate is 15 sheets or less, the peeling strength at which the joining means and the installation surface are peeled off is higher than the tensile force when the sheets in the aggregate accommodated in the sheet container are taken out from the outlet. According to this aspect, since the peeling strength is higher than the tensile force, it is possible to suppress the sheet container from rising with respect to the installation surface when taking out the sheets, and the sheets can be taken out smoothly.

[0014] According to a preferred aspect, the invention according to Aspect 6 may have the following features in the invention according to either Aspect 4 or Aspect 5. The suppressing means is an engaging means for detachably engaging the sheet container with the installation surface. In a state where the number of sheets in the aggregate is 15 sheets or less, the separation strength at which the engagement between the engaging means and the installation surface is separated is higher than the tensile force when the sheets in the aggregate accommodated in the sheet container are taken out from the outlet. According to this aspect, since the separation strength is higher than the tensile force, it is possible to suppress the sheet container from rising with respect to the installation surface when taking out the sheets, and the sheets can be taken out smoothly.

[0015] According to a preferred aspect, the invention according to Aspect 7 may have the following features in the invention according to any one of Aspects 1 to 6. The opening area of the outlet is 4.0 cm 2 or more. According to this aspect, the opening area of the outlet is 4.0 cm 2As described above, it is possible to secure the area of the passage of the sheet and suppress the resistance at the time of sheet extraction. Therefore, the tensile force of the sheet can be reduced, the sheet container can be prevented from rising, and the sheet can be smoothly extracted.

[0016] According to a preferred aspect, the invention according to aspect 8 may have the following features in the invention according to any one of aspects 1 to 7. The sheet container has a take-out surface provided with the take-out port and a storage side surface adjacent to the take-out surface and covering the side of the aggregate. The sheet container has a separation guiding portion that guides the separation of the sheets taken out from the take-out port. The rigidity of the separation guiding portion is 0.9 times or more and 1.1 times or less the rigidity of the storage side surface. According to this aspect, the separation guiding portion is difficult to deform when hitting the sheet and does not follow the sheet too much when the sheet is taken out. Therefore, it is possible to suppress the tensile force from becoming too high and suppress the sheet container from rising while smoothly taking out the sheet.

[0017] According to a preferred aspect, the invention according to aspect 9 may have the following features in the invention according to any one of aspects 1 to 8. The sheet container has a take-out surface provided with the take-out port and a storage side surface adjacent to the take-out surface and covering the side of the aggregate. The sheet container has a separation guiding portion that guides the separation of the sheets taken out from the take-out port. The separation guiding portion and the peripheral region disposed around the separation guiding portion on the take-out surface are made of the same material. The separation guiding portion is configured to be as difficult to deform as the peripheral region covering the upper surface of the aggregate. Therefore, the separation guiding portion is difficult to deform when hitting the sheet and does not follow the sheet too much when the sheet is taken out. Therefore, it is possible to suppress the tensile force from becoming too high and suppress the sheet container from rising while smoothly taking out the sheet.

[0018] According to a preferred embodiment, the invention according to aspect 10 may have the following features in the invention according to any one of aspects 1 to 9. The sheet container has a plurality of separation guiding portions that guide the separation of the sheets taken out from the outlet. The minimum distance between the separation guiding portions is 5 mm or more.

[0019] According to a preferred embodiment, the invention according to aspect 11 may have the following features in the invention according to any one of aspects 1 to 10. In a plan view of the sheet container, the center of gravity of the sheet container overlaps with the outlet. According to this embodiment, since the center of gravity of the sheet container overlaps with the outlet, the force for pulling out the sheet is likely to be applied to the center of gravity of the sheet container, and the inclination of the sheet container during extraction can be suppressed. According to this embodiment, the minimum distance between the separation guiding portions is 5 mm or more, the width of the passage for the sheet can be ensured, and the resistance during sheet extraction can be suppressed. Therefore, the pulling force of the sheet can be reduced, the floating of the sheet container can be suppressed, and the sheet can be taken out smoothly.

[0020] (2) Overall configuration of the sheet container according to the embodiment Hereinafter, with reference to the drawings, the sheet container 1 according to the embodiment will be described. In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the ratios of the respective dimensions are different from the actual ones. Therefore, specific dimensions and the like should be determined with reference to the following description. Also, there may be portions where the relationships and ratios of the dimensions to each other are different between the drawings. FIG. 1 is an exploded perspective view of the sheet container 1 according to the embodiment as viewed from the upper surface 11 side. FIG. 2 is a plan view of the sheet container 1 according to the embodiment. FIG. 3 is a cross-sectional view taken along line A-A shown in FIG. 2. FIGS. 1 to 3 show the sheet container 1 together with the assembly 40 and the package 50. FIG. 1 shows a state in which the first housing body 31 and the second housing body 32 of the sheet container 1 are separated and the assembly 40 is taken out from the housing space. FIGS. 2 to 4 show a state in which the assembly 40 and the package 50 are housed in the housing space 22.

[0021] The sheet container 1 is configured to accommodate an aggregate 40 of a plurality of sheets 41. The sheet container 1 may have an upper surface 11, a bottom surface 12 facing the upper surface 11, and side surfaces covering the side surfaces of the aggregate 40. The side surfaces may have a left surface 15, a right surface 16, a front surface 13, and a rear surface 14. In the sheet container 1 of the present embodiment, an outlet 23 is provided on the upper surface 11, and the upper surface 11 constitutes the "take-out surface" of the present invention. The side surfaces 13 to 16 are adjacent to the upper surface 11 which is the take-out surface, and are configured to cover the sides of the aggregate 40, and constitute the "accommodation side surfaces" of the present invention.

[0022] The aggregate 40 of the present embodiment is an aggregate of a plurality of laminated sheets 41, has a substantially rectangular parallelepiped shape, and the sheet container 1 has a rectangular parallelepiped shape. The sheet container 1 has a third direction D3 along the stacking direction of the sheets 41 in the aggregate 40, and a first direction D1 and a second direction D2 that extend in the plane direction of the sheet 41 and are perpendicular to each other. In a form in which the sheet 41 is folded, the first direction D1 may be a direction along the fold FL of the aggregate 40. The first direction D1 may be the longitudinal direction of the sheet container 1 as in the present embodiment, or may be the short-side direction of the sheet container 1 in a modified example. Further, in a case where the aggregate 40 is a cylindrical shape in which the sheet 41 is wound in a roll shape, the sheet container 1 may also be a cylindrical shape.

[0023] The sheet 41 may be a dry sheet or a moistened sheet (e.g., a wet tissue). The sheet 41 in the present embodiment is a wet tissue. Also, the aggregate may be one in which a plurality of sheets 41 are continuous via a weak portion, or may be one in which a plurality of separated sheets 41 as in the present embodiment are laminated. The weak portion can be exemplified by, for example, a perforation. The aggregate 40 may be an aggregate of sheets 41 laminated in a plurality in the third direction D3. The sheet 41 may be folded at least based on a fold line FL along the first direction D1. In the folded state, the sheets 41 adjacent to each other in the third direction D3 may be alternately arranged. The aggregate 40 may be folded before or after the fold line FL by a fold line other than the fold line FL. That is, the sheet 41 may be folded based on a fold line along the second direction D2 and then folded based on a fold line along the first direction D1. The fold line FL along the first direction D1 of the present invention is a fold line that serves as a base point when the sheet 41 is unfolded from the aggregate 40. In a modified example, the aggregate 40 may be one in which a plurality of sheets 41 are wound in a roll shape, a plurality of sheets 41 may be continuous via a weak portion, and the continuous sheets may be wound in a roll shape.

[0024] The aggregate 40 may be packaged by a packaging body 50. The packaging body 50 is configured to enclose the entire aggregate 40. The packaging body 50 may have a packaging opening 52 that serves as an outlet for the sheet 41. The packaging body 50 may be composed of a film. The material of the film is not particularly limited, and may be, for example, a mixture of polyethylene and polypropylene. The packaging opening 52 may be disposed on the upper surface 11 side. The aggregate 40 may not be packaged by the packaging body 50. That is, the sheet container 1 may accommodate the aggregate 40 packaged by the packaging body 50, or may accommodate the aggregate 40 not packaged by the packaging body 50.

[0025] The sheet container 1 has at least a storage space 22 for storing the assembly 40 and an outlet 23 for the sheet stored in the storage space 22. The storage space 22 is a space for storing the assembly 40 and is a space surrounded by a side surface, an upper surface 11, and a bottom surface 12. The outlet 23 is an opening for taking out the sheet 41 and is connected to the storage space 22. When the assembly 40 is in a form packaged by the packaging body 50, the outlet 23 is arranged so as to overlap at least a part of the packaging opening 52. The outlet 23 may be arranged so as to overlap a part of the packaging opening 52 or may be arranged so as to overlap the entire area of the packaging opening 52. When the assembly 40 is in a form packaged by the packaging body 50, the sheet 41 is taken out from the sheet container 1 through the packaging opening 52 and the outlet 23.

[0026] The sheet container 1 may have a separation guiding portion 24. The user pulls out the sheet 41 to the outside of the sheet container 1 through the outlet 23 (in a form having the packaging body 50, through the outlet 23 and the packaging opening 52). At this time, when the separation guiding portion 24 hits the sheet 41 and there is a possibility that both the sheet to be taken out and the next sheet 41 (located on the bottom surface side) are pulled out together, the separation guiding portion 24 functions so that only the sheet to be taken out is pulled out.

[0027] The sheet container 1 may have a plurality of members that engage with each other. Specifically, it may have a first housing body 31 and a second housing body 32. The first housing body 31 is provided with a bottom surface 12 of the sheet container 1 and a housing side surface extending upward (in the third direction D3) from the bottom surface 12. In a state where the second housing body 32 is not disposed on the first housing body 31, an opening for taking in and out the assembly 40 is formed on the upper surface 11 side of the first housing body 31. The second housing body 32 is located on the upper surface 11 side of the first housing body 31 and is configured to be able to open and close the opening of the first housing body 31. The second housing body 32 is provided with a bottom surface 12 of the sheet container 1 and a housing side surface extending upward (in the third direction D3) from the bottom surface 12. The length (height) of the second housing body 32 in the third direction D3 may be shorter than the length of the first housing body 31 in the third direction D3. The length of the first housing body 31 in the third direction D3 may be longer than the length of the assembly 40 in the third direction D3. Preferably, the length of the accommodation space 22 in the third direction may be longer than the length of the assembly 40 in the third direction D3.

[0028] As shown in FIG. 1, the second housing body 32 may have a discharge port 23 for the sheet 41, a separation guiding portion 24, and a lid portion 26 that can open and close the discharge port 23. The lid portion 26 may realize a state of covering the discharge port 23 and a state of exposing the discharge port 23 with the hinge portion 28 as an opening and closing base point. FIG. 1 shows a state where the lid portion 26 is opened and the discharge port 23 is exposed, and FIG. 2 shows a state where the lid portion 26 is closed and the discharge port 23 is covered by the lid portion 26. When the user takes out the sheet 41, an operation of opening the lid portion 26 with the hinge portion 28 as a base point is performed, and when the sheet 41 is not taken out, an operation of closing the lid portion 26 to cover the discharge port 23 is performed. Note that the sheet container 1 is not limited to a form having the first housing body 31 and the second housing body 32, and may be in other forms.

[0029] (3) Prevention of the sheet container from floating up Next, in the sheet container 1 configured as described above, a configuration for suppressing the entire sheet container 1 from rising when the sheet 41 is taken out will be described. The configuration for suppressing the entire sheet container 1 from rising is roughly divided into a first form and a second form. First, the first form will be described. The sheet container 1 according to the first form has a gravity of the sheet container 1 that houses the aggregate 40 higher than the tensile force when taking out the sheet 41 of the aggregate 40 from the outlet 23 in a small number state where the number of sheets 41 in the aggregate 40 is 15 or less. The small number state where the number of sheets 41 in the aggregate 40 is 15 or less means that the remaining number of sheets 41 is small, the gravity of the entire sheet container 1 becomes light, and the entire sheet container 1 is particularly likely to rise when the sheet 41 is taken out. In this small number state, since the gravity of the sheet container 1 is higher than the tensile force when taking out the sheet 41 of the aggregate 40 housed in the sheet container 1 from the outlet 23, the gravity of the sheet container 1 suppresses the sheet container 1 from rising, and the sheet 41 can be taken out smoothly.

[0030] FIG. 5 is a diagram showing the gravity and tensile force in the small number state of the sheet container according to Examples 1 to 4. In the sheet containers according to Examples 1 to 4, it was found that even in the small number state, when pulling out the sheet, the sheet container 1 is suppressed from rising, and the sheet 41 can be taken out smoothly. In the small number state, the average value of the gravity of the sheet container 1 may be higher than the average value of the tensile force when taking out the sheet 41 from the outlet 23. Also, the maximum value of the gravity of the sheet container 1 in the small number state may be higher than the maximum value of the tensile force in the small number state when taking out the sheet 41 from the outlet 23. Further, the minimum value of the gravity of the sheet container 1 in the small number state may be higher than the minimum value of the tensile force in the small number state when taking out the sheet 41 from the outlet 23. Preferably, in any state (from 1 sheet state to 15 sheets state) in the small number state, the gravity of the sheet container 1 may be higher than the tensile force when taking out the sheet 41 from the outlet 23.

[0031] Here, the gravity of the sheet container 1 is the gravity in the state where the aggregate in the small number of sheets state (the number of sheets is from 1 to 15) is accommodated in the sheet container 1. In the aggregate 40 packaged by the package 50, it is the gravity in the state where the aggregate 40 packaged by the package 50 is accommodated in the sheet container 1. Specifically, it can be obtained by Equation 1. (Equation 1) Gravity of the sheet container (including the aggregate) (N) = Weight of the sheet container (including the aggregate) (g) * 0.0098

[0032] When taking out the sheet 41 of the aggregate 40 (the number of sheets is from 1 to 15) accommodated in the sheet container 1 from the outlet 23, the tensile force is the tensile force of the sheet 41 in the small number of sheets state and can be measured by the following method. FIG. 4 is a view based on a cross section along the B - B line shown in FIG. 2 and is a view for explaining the method of measuring the tensile force in the small number of sheets state. When measuring the tensile force, set the number of the aggregate 40 to 15 and pull out one sheet 41 from the outlet 23. The pulling - out length of the sheet 41 only needs to be 10 mm (the length for hooking the digital force gauge_FGP - 2). In this state, hook the tip 201 of the digital force gauge 200 to the tip of the sheet 41 and pull the digital force gauge upward to pull out the sheet 41. Measure until the sheet 41 is completely pulled out from the outlet, and take the maximum value as the tensile force (N) of the sheet. Repeat this, measure the tensile force for each number of sheets, and repeat until it reaches 0 sheets. Take the average value of the tensile forces as the tensile force in the small number of sheets state. The tensile force for 15 sheets is the tensile force when pulling the remaining 15 sheets, and assume there are 14 sheets remaining in the state where the sheet has been pulled out.

[0033] The average value of the tensile force in the small number state may be 3.0 N or less. The average value is the average value of the tensile forces measured for each of the tensile forces from 15 sheets to 0 sheets. Since the tensile force in the small number state is 3.0 N or less and is relatively low, the user can easily pull out the sheet 41 without applying a large force. Since the sheet 41 can be pulled out without applying a large force, excessive force is not applied when pulling out the sheet 41, and it is possible to suppress the sheet container 1 from tilting due to the application of excessive force, and the sheet 41 can be pulled in the intended direction, and the lifting of the sheet container 1 during pulling can be further suppressed.

[0034] In the small number state, the tensile force when taking out the sheet 41 of the aggregate 40 accommodated in the sheet container 1 from the outlet 23 may be lower than the tensile force when taking out the sheet 41 of the aggregate 40 not accommodated in the sheet container 1 from the packaging opening 52. According to this configuration, by accommodating in the sheet container 1, it is possible to further suppress the lifting of the sheet container 1 when pulling out, as compared with the case where the sheet 41 is used with the aggregate 40 alone.

[0035] More specifically, by accommodating the aggregate in the sheet container 1, a force that presses the sheet container 1 due to the gravity of the sheet container 1 acts, and the upward floating of the sheet container 1 can be suppressed. Further, by accommodating the aggregate 40 in the sheet container 1 having the separation guiding portion 24, the drawn sheet 41 is in a state of being caught by the separation guiding portion 24. In a state of being caught by the separation guiding portion 24, not only the drawn sheet 41 but also the next drawn sheet 41 may float, and the sheets 41 may be separated from each other. Therefore, the tensile force of the sheet 41 is reduced, and the upward floating of the sheet container 1 can be suppressed. Furthermore, when the aggregate 40 packaged in the package 50 is not accommodated in the sheet container 1, when the sheet 41 is pulled, the package 50 is deformed, and the inner surface (upper surface) of the package 50 is in close contact with the sheet 41, and the frictional force increases the tensile force. On the other hand, when the aggregate 40 packaged in the package 50 is accommodated in the sheet container 1, even if the package 50 is deformed, the package 50 is pressed by the inner surface of the sheet container 1, and the package 50 and the sheet 41 do not come into excessive close contact. Therefore, it is possible to suppress an increase in the frictional resistance of the sheet 41 against the inner surface of the package, maintain the tensile force of the sheet 41 low, and suppress the upward floating of the sheet container 1.

[0036] FIG. 6 is a diagram showing the tensile force of the assembly housed in the sheet container 1 according to Example 1 and Example 4, and the tensile force of the assembly 40 according to Example 5. The assembly according to Example 5 is the tensile force in a state where it is not housed in the sheet container. The assembly according to Example 5 is the same as the assembly used in the sheet container 1 according to Example 1 and Example 4. The assemblies 40 according to Examples 1 to 4 are packaged by the packaging body 50. The tensile force when taking out the sheet 41 of the assembly 40 not housed in the sheet container 1 in the form in which the assembly 40 is packaged by the packaging body 50 from the packaging opening 52 is the tensile force when taking out the sheet 41 from the packaging opening 52. The measurement method can be measured in the same way as the tensile force when taking out the sheet 41 from the sheet container 1. Also, the tensile force when taking out the sheet 41 of the assembly 40 not housed in the sheet container 1 in the form in which the assembly 40 is not packaged by the packaging body 50 is the tensile force when separating the sheet 41 from the assembly 40, and it is measured until one sheet 41 is separated from the assembly 40, and the maximum value is taken as the tensile force of the sheet 41.

[0037] Next, a second form of the configuration for suppressing the entire sheet container 1 from rising when taking out the sheet 41 will be described. FIG. 7 is a diagram showing the sheet container 1X according to the second form. FIG. 7 is a diagram based on the same cross-section as the cross-section shown in FIG. 3. The sheet container 1X according to the second form has a suppressing means 70 for suppressing the sheet container 1X from rising from the installation surface LS on which the sheet container 1X is installed. By the suppressing means 70, the sheet container 1X is suppressed from rising, and the sheet 41 can be taken out smoothly. The suppressing means 70 may be provided on the bottom surface 12 of the sheet container 1 as shown in FIG. 7, may be provided on other outer surfaces, or may be provided on a portion other than the outer surface of the sheet container 1 (for example, inside). The suppressing means 70 may be one that suppresses rising with only the sheet container 1 without requiring supply from the outside, such as a motor that receives power supply.

[0038] The suppression means 70 may be a joining means for detachably joining the sheet container 1X to the installation surface LS. The joining means may be any means that can be detachably joined to the installation surface LS, and can be constituted by, for example, a suction cup, an adhesive tape, and a magnet. In a state where the number of sheets 41 of the aggregate 40 is 15 sheets or less, the peeling strength at which the joining means and the installation surface LS are peeled may be higher than the tensile force when the sheet 41 of the aggregate 40 accommodated in the sheet container 1X is taken out from the outlet 23. According to this configuration, since the peeling strength is higher than the tensile force, it is possible to suppress the sheet container 1X from rising with respect to the installation surface LS when the sheet 41 is taken out, and the sheet 41 can be taken out smoothly. The measurement of the peeling strength at which the joining means and the installation surface are peeled is to fix the Digital force gauge FGP-2 to the sheet coming out of the container with a hook and measure the numerical value when the Digital force gauge FGP-2 is lifted straight up.

[0039] The suppression means 70 may be an engaging means for detachably engaging the sheet container 1X with the installation surface LS. Examples of the engaging means include a hook that catches on the installation surface LS, a screw that is screwed into the installation surface LS, a surface fastener that catches on the installation surface LS, a button that is hung on the installation surface, a recess into which the installation surface can be inserted, and a fastener that engages with the installation surface. In the state of a small number of sheets, the separation strength at which the engagement between the engaging means and the installation surface LS is separated may be higher than the tensile force when the sheet 41 of the aggregate 40 accommodated in the sheet container 1X is taken out from the outlet 23. According to this configuration, since the separation strength is higher than the tensile force, it is possible to suppress the sheet container 1X from rising with respect to the installation surface when the sheet 41 is taken out, and the sheet 41 can be taken out smoothly.

[0040] Next, a configuration suitable for the first and second forms will be described. The opening area of the outlet 23 may be 4.0 cm 2 or more. The opening area of the outlet 23 is 4.0 cm 2As described above, the passage area of the sheet 41 can be secured, and the resistance when taking out the sheet 41 can be suppressed. Therefore, the tensile force of the sheet 41 can be reduced, the sheet container 1 can be prevented from rising, and the sheet 41 can be taken out smoothly.

[0041] The rigidity of the separation guiding portion 24 may be 0.9 times or more and 1.1 times or less the rigidity of the housing side surface. The rigidity of the separation guiding portion 24 is the same as or close to the rigidity of the housing side surface. The separation guiding portion 24 is configured to be difficult to deform equally to the housing side surface surrounding the aggregate 40. Therefore, the separation guiding portion 24 is difficult to deform when hitting the sheet, and does not follow the sheet 41 too much when taking out the sheet 41. Therefore, it is possible to suppress the tensile force from becoming too high and smoothly take out the sheet 41 while suppressing the sheet container 1 from rising.

[0042] The separation guiding portion 24 and the peripheral region disposed around the separation guiding portion 24 on the take-out surface may be made of the same material. The peripheral region is a region extending outward in the plane direction from the separation guiding portion 24. The boundary between the separation guiding portion 24 and the peripheral region may be, for example, a virtual line connecting the root portion of the separation guiding portion 24 that bulges convexly inward. The separation guiding portion 24 is configured to be difficult to deform equally to the peripheral region covering the upper surface 11 of the aggregate 40. Therefore, the separation guiding portion 24 is difficult to deform when hitting the sheet, and does not follow the sheet 41 too much when taking out the sheet 41. Further, since the separation guiding portion 24 is integrated with the peripheral region, no rigidity difference is formed with the peripheral region, and it becomes more difficult to deform, and does not follow the sheet 41 too much when taking out the sheet 41. Therefore, it is possible to suppress the tensile force from becoming too high and smoothly take out the sheet 41 while suppressing the sheet container 1 from rising.

[0043] A plurality of separation guiding portions 24 may be provided. In the present embodiment, two separation guiding portions 24 are provided at intervals in the third direction D3. The minimum distance between the separation guiding portions 24 may be 5 mm or more. When the minimum distance between the separation guiding portions is 5 mm or more, the width of the passage for the sheet 41 can be secured, and the resistance when taking out the sheet 41 can be suppressed. Therefore, the tensile force of the sheet 41 can be reduced, the floating of the sheet container 1 can be suppressed, and the sheet 41 can be taken out smoothly. Preferably, the minimum distance between the separation guiding portions may be 8 mm or more, and more preferably 10 mm or more.

[0044] In the plan view of the sheet container 1 shown in FIG. 2, the center of gravity of the sheet container 1 may overlap with the take-out port 23. If the center of gravity of the sheet container 1 is deviated from the take-out port 23, when taking out the sheet 41, the force pulling the sheet 41 upward deviates from the center of gravity of the sheet container 1, and there is a risk that the sheet container 1 may tilt or fall when taking out the sheet 41. However, since the center of gravity of the sheet container 1 overlaps with the take-out port 23, the force pulling out the sheet 41 is likely to act on the center of gravity of the sheet container 1, and the tilt of the sheet container 1 during taking out can be suppressed.

[0045] An antistatic agent may be applied to the surface of the sheet container 1. Generation of static electricity on the surface can be suppressed, adhesion of fine foreign matters due to static electricity can be suppressed, and the sheet container 1 can be kept hygienic. Examples of the antistatic agent include nonionic, anionic, cationic, and amphoteric surfactants, and polyether-based, quaternary ammonium salt-based, sulfonic acid-based, and betaine-based polymer antistatic agents.

[0046] (4) Sheet Container Considerate of the Environment In recent years, there has been an increasing concern for the environment and an enhanced awareness of reducing disposable items, and sheet containers that can be used multiple times are being accepted. However, on the other hand, after being used a certain number of times, they are discarded and new sheet containers are sought. As a result of the applicant's intensive research, in particular, when a part that is easily touched by the user (for example, the lid) gets dirty, unease regarding hygiene occurs and the sheet container is replaced. The sheet container of the present embodiment may be configured to reduce waste and be more environmentally considerate.

[0047] Next, a sheet container that is environmentally considerate will be described in detail. The first housing body 31 and the second housing body 32 are configured to be separable. Therefore, when one of them needs to be replaced due to damage or dirt, only that one can be replaced. When a part of the sheet container 1 needs to be replaced, instead of replacing the entire sheet container 1, only a part can be replaced, reducing waste and being more environmentally considerate. Also, the first housing body 31 has a function of housing the aggregate 40, and the second housing body 32 has a function of separating the sheets 41 from each other. The first housing body 31 and the second housing body 32 have different functions, and also different shapes and manufacturing methods. By configuring the first housing body 31 and the second housing body 32 as separate bodies, an appropriate material and shape suitable for each function can be selected, and design limitations can be reduced.

[0048] At least one of the first housing body 31 and the second housing body 32 has an engaging portion 60 that engages with the other in a separable manner. The first housing body 31 and the second housing body 32 are configured to be separable and can be engaged and separated via the engaging portion. The engaging portion 60 may be provided on both the first housing body 31 and the second housing body 32, or may be provided on one of them. The engaging portion 60 may be any mechanism that fits together, and examples include hooks, hinges, ribs, etc. The engaging portion 60 may be made of a material different from the main material of the second housing body 32 and the main material of the first housing body 31.

[0049] The engaging portion 60 of the present embodiment is composed of a protruding portion 61 protruding downward in the second housing body 32, an inner wall portion 62 located outside the protruding portion 61 in a plan view in the first housing body 31, and a flexible member (silicon) 63 disposed between the protruding portion 61 and the inner wall portion 62 and having flexibility. When the second housing body 32 is attached to the first housing body 31, the flexible member 63 is deformed and the second housing body 32 and the first housing body 31 are fitted together. The flexible member 63 is in close contact with the protruding portion 61 and the inner wall portion 62, maintaining the engaged state of the second housing body 32 and the first housing body 31, suppressing the dropping and falling off of one of the second housing body 32 and the first housing body 31, and also enhancing the airtightness of the assembly 40 accommodated inside. Further, as another form of the engaging portion, it may be configured such that a receiving protrusion provided on the upper surface of the first housing body 31 and a lid protrusion provided on the bottom surface of the second housing body 32 are fitted together.

[0050] The density of one of the first housing body 31 and the second housing body 32 is 1 g / cm 3 or more. The density of the other of the first housing body 31 and the second housing body 32 is less than 1 g / cm 3 When the applicant conducted intensive research, when the density of the first housing body 31 and the density of the second housing body 32 were in the same form, since physical properties such as the feel and ease of deformation were the same, it was sometimes difficult to engage or separate them from each other. However, since the density of the first housing body 31 and the density of the second housing body 32 are different and their physical properties are different, it is easy to engage or separate them from each other and they can be easily assembled.

[0051] Preferably, the density of the second housing body 32 is less than 1 g / cm 3 and the density of the first housing body 31 is 1 g / cm 3The above may be the case. That is, the density of the second housing body 32 may be lower than the density of the first housing body 31. According to this aspect, since the density of the second housing body 32 is low and the density of the first housing body 31 is high, the center of gravity of the sheet container 1 is located downward. Therefore, when the sheet 41 is taken out, the sheet container 1 is less likely to float up, and the sheet 41 can be taken out smoothly. In addition, since the density of the second housing body 32 is low, the second housing body 32 is light, and the second housing body 32 can be easily operated, improving the operability.

[0052] In a modified example, the density of the second housing body 32 is 1 g / cm 3 or more, and the density of the first housing body 31 may be less than 1 g / cm 3 That is, the density of the second housing body 32 may be higher than the density of the first housing body 31. According to the modified example, since the density of the second housing body 32 is high and the density of the first housing body 31 is low, the center of gravity of the sheet container 1 is located upward. Therefore, the second housing body 32 is less likely to float up, and the airtightness of the sheet container 1 can be enhanced. In addition, when the aggregate 40 contains a volatile chemical solution (in the case of a wet tissue), the engagement of the second housing body 32 and the first housing body 31 is in a state where the second housing body 32 is weighted, reducing the volatilization of the chemical solution caused by the second housing body 32 accidentally coming off or the engagement state of the engaging portion 60 becoming loose, and suppressing the deterioration of the function of the aggregate 40.

[0053] The materials of the first housing body 31 and the second housing body 32 may be any materials that can be processed into the shape of the sheet container 1, and are not particularly limited. Examples of the materials of the first housing body 31 and the second housing body 32 include polypropylene, polyethylene, wood (cedar, cypress, cherry, etc.), silicon, polyoxymethylene (homopolymer), polyoxymethylene (copolymer), polyester, acrylic, acrylonitrile butadiene styrene, pottery, glass, stainless steel, alumina, ceramics, zirconia, steatite, and enamel. The first housing body 31 and the second housing body 32 may be formed of a single material of these materials or may be formed of a combined material of these materials. Table 1 below shows the densities of the main materials. Materials with a density less than 1 g / cm 3 are regarded as low density, and materials with a density of 1 g / cm 3 or more are regarded as high density. In the present invention, one of the first housing body 31 and the second housing body 32 is configured to be a low-density material, and the other of the first housing body 31 and the second housing body 32 is configured to be a high-density material.

[0054]

Table 1

[0055] At least one of the first housing body 31 and the second housing body 32 may be formed of a thermoplastic resin. Thermoplastic resins are easy to mold, have a high degree of design freedom, and are easy to realize the intended shape. Also, both the first housing body 31 and the second housing body 32 may be formed of a thermoplastic resin. Examples of the thermoplastic resin include polyethylene, polypropylene, polystyrene, AS resin, ABS resin, polyvinyl chloride, vinyl chloride resin, acrylic resin, methacrylic resin, PET resin, polyethylene terephthalate, PVA resin, polyvinyl alcohol, and silicone resin.

[0056] The second housing body 32 is formed of a thermoplastic resin. The shape of the separation guiding portion 24 in a plan view of the second housing body 32 may be a convex shape that bulges toward the inside of the outlet 23. The separation guiding portion 24 may protrude inward from the outer edge of the outlet 23 and be configured to guide the separation of the sheets 41. More specifically, the separation guiding portion 24 protrudes from the center of one of the outlets 23 in the first direction D1 and the second direction D2 toward the inside of the other of the first direction D1 and the second direction D2 to guide the separation of the sheets 41. The separation guiding portion 24 of the present embodiment may be a portion that protrudes inward in the second direction D2 from the outer edge of the outlet 23 in the second direction D2. In a modified example, the separation guiding portion 24 may be a portion that protrudes inward in the first direction D1 from the outer edge of the outlet 23 in the first direction D1. According to the second housing body 32 made of a thermoplastic resin, it is easy to mold, has a high degree of design freedom, and can easily realize the intended shape. While considering the environment, the functional aspect of the ease of taking out the sheet 41 can also be improved.

[0057] As an index indicating the ease and difficulty of deformation of the first housing body 31 and the second housing body 32, the Young's modulus of the first housing body 31 may be higher than the Young's modulus of the second housing body 32. The Young's modulus is the tensile elastic modulus, which is the tensile stress within the tensile proportional limit and the corresponding strain. The higher the value, the more difficult it is to deform, and it can be measured by the formula shown in Equation 1 below.

Equation

[0058] Also, as another index indicating the ease of deformation of the first housing body 31 and the second housing body 32, the bending strength of the first housing body 31 may be higher than the bending strength of the second housing body 32. The bending strength is calculated from a predetermined formula by horizontally supporting a test piece at two fulcrums, applying a load from above to the central part to bend the test piece, and reading the maximum load before breakage. The bending strength of the first housing body 31 may be 320 MPa or more. Also, as another index indicating the ease of deformation of the first housing body 31 and the second housing body 32, the compression stiffness of the first housing body 31 may be higher than the compression strength of the second housing body 32. The compression strength represents the material strength that can withstand the compression load. The compression per unit area refers to the step load. The compression strength of the first housing body 31 may be 900 MPa or more.

[0059] The first housing body 31 is difficult to deform, the second housing body 32 is easy to deform, and they are easy to engage and separate from each other. Also, since the first housing body 31 is difficult to deform, it is easy to hold the accommodation space 22, and it is also possible to reduce reinforcing parts such as reinforcing ribs for maintaining the accommodation space 22. By not providing the reinforcing part, the designability can be improved. Also, by not providing the reinforcing part, the first housing body 31 can be easily cleaned and is more easily reusable. Also, since the second housing body 32 is easier to deform than the first housing body 31, the opening and closing operation of the second housing body 32 becomes easier.

[0060] The weight of the sheet housing body 1 may be larger than the extraction resistance value when extracting the sheet 41 from the extraction port 23. Since the weight of the sheet housing body 1 is heavy, it is difficult for the sheet housing body 1 to float up when extracting the sheet 41, and the operability when extracting the sheet 41 can be improved. Here, the weight of the sheet housing body 1 is the mass (g) of the sheet housing body 1 × gravitational acceleration (9.8 m / S 2) can be calculated. The extraction resistance value is measured using a test body including the packaging body in a form in which the assembly 40 is packaged by the sheet container 1, the assembly 40 accommodated in the sheet container 1, and the packaging body 50. The extraction resistance value is the maximum value when a single sheet 41 is pulled out 5 cm from the outlet 23 in the test body, the pulled-out portion is hooked on a digital force gauge, and the sheet 41 is pulled out from the outlet 23. Also, since variations occur at the start and end of using the assembly 40, it is preferable to measure the overall average (10 sheets or more) or starting from the 10th sheet and thereafter.

[0061] The inner surface of the first housing body 31 may be a smooth surface without ribs. Here, a rib is a protrusion protruding inward from the inner surface and is a concept that does not include protrusions with a height of 2 mm or less. According to this aspect, compared with a form having ribs, the inner surface of the first housing body 31 can be easily cleaned and is easy to use for a long time. Also, due to the shape without ribs, it has a simple design appearance, improves the aesthetics, and makes it easier to harmonize the sheet container with the interior.

[0062] As a result of the applicant's intensive research, the number of users who constantly use the assembly 40 such as wet tissues has been increasing in recent years. Such users often keep the sheet container 1 constantly placed in the living room instead of taking it out from a shelf or the like when using the sheet container 1. Therefore, the designability of the sheet container 1 and the harmony of the sheet container 1 with the interior are required. The sheet container 1 can make the appearance of the first housing body 31 and the appearance of the second housing body 32 different, and can improve the designability of the sheet container 1.

[0063] The first housing body 31 and the second housing body 32 may be provided integrally or separately. For example, a plurality of first housing bodies 31 made of different materials are provided, and a plurality of second housing bodies 32 made of different materials are provided, and a purchaser can select a first housing body 31 and a lid body respectively, and use the sheet storage body 1 in a preferred combination. Also, according to the place of use, purpose of use, awareness of the environment, lifestyle, etc. of the sheet storage body 1, an appropriate combination of materials can be selected. For example, when used in an office, the first housing body 31 and the second housing body 32 made of materials suitable for the office interior can be selected. Also, when used in a vehicle, the first housing body 31 and the second housing body 32 made of materials with high durability can be selected. By allowing the user to select and use the desired materials in this way, the awareness of continuous use is enhanced, waste is reduced, and more consideration can be given to the environment.

[0064] (5) Sheet storage body group Next, the sheet storage body group will be described. The sheet storage body group includes a plurality of first housing bodies 31 and a plurality of second housing bodies 32. The first housing body 31 and the second housing body 32 constituting the sheet storage body group may be included in the first housing body 31 and the second housing body 32 constituting the above-described sheet storage body 1. The first housing body 31 and the second housing body 32 constituting the sheet storage body group are configured to be separable. At least one of the first housing body 31 and the second housing body 32 has an engaging portion 60 that is separably engaged with the other. The second housing body 32 has a separation guiding portion 24 that guides the separation of the sheets taken out from the take-out port 23. The density of the first housing body 31 is 1 g / cm 3 or more. The density of the second housing body 32 is 1 g / cm 3 less than.

[0065] The plurality of first housing bodies 31 have the same shape but different materials. Also, the plurality of second housing bodies 32 have the same shape but different materials. The plurality of first housing bodies 31 all have the same shape and can be used in combination with any of the plurality of second housing bodies 32. Similarly, the plurality of second housing bodies 32 all have the same shape and can be used in combination with any of the plurality of first housing bodies 31. Therefore, the user can combine one of the plurality of first housing bodies 31 and one of the plurality of second housing bodies 32 to form the sheet housing body 1 that houses the assembly 40. Thus, the user can select an appropriate combination of materials according to the place of use, purpose of use, awareness of the environment, lifestyle, etc. of the sheet housing body 1. Also, when one of them needs to be replaced due to damage or dirt, only that one can be replaced. When a part of the sheet housing body 1 needs to be replaced, only a part can be replaced without replacing the entire sheet housing body, reducing waste and being more environmentally considerate. Also, since the density of the second housing body 32 is lower than that of the first housing body 31 and their physical properties are different, they can be easily engaged or separated from each other and can be easily assembled.

[0066] As described above, the present invention has been described in detail using the above-described embodiments. However, it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in this specification. The present invention can be implemented as modifications and variations without departing from the spirit and scope of the present invention as defined by the claims. Therefore, the description in this specification is for illustrative purposes and has no restrictive meaning for the present invention. In the above-described embodiments, the sheet housing body 1 has been described. However, the present invention may be constituted only by the first housing body 31 used together with the second housing body 32 in the sheet housing body 1, or may be constituted only by the second housing body 32 used together with the first housing body 31 in the sheet housing body 1.
