Detailed Description

(1) Summary of the embodiments

At least the following matters will be clarified from the description of the present specification and drawings.

The wet tissue storage container according to one aspect includes: a container body which accommodates a collection of wet tissues and has a take-out opening which serves as a take-out opening for each wet tissue when used; a lid body capable of opening and closing the take-out opening of the container body; and a packaging sheet for internally packaging the container body and the cover body. At least one of the container body and the cover is provided with a groove recessed toward the inside of the storage container. The packaging sheet has a frangible portion which is more likely to break than the surrounding. At least a part of the fragile portion is provided in a region overlapping with the groove portion. According to this aspect, the package sheet can be opened via the frangible portion of the package sheet. At this time, since the fragile portion overlaps the groove portion, a space of the groove portion is disposed inside the fragile portion. Therefore, the force for opening the package sheet is easily applied to the frangible portion, and the package sheet can be easily broken, so that the operation of opening the storage container can be easily performed.

According to a preferred aspect, the container body may have an opening surface to which the lid is attached, and the frangible portion may overlap the groove portion in a region overlapping a surface other than the opening surface of the container body. According to this aspect, when a force is applied to the fragile portion, the force is not applied to the opening surface, and the force is applied to a surface other than the opening surface. Therefore, breakage of the opening and closing member such as the operation button of the opening cover due to the application of force at the time of opening can be suppressed.

According to a preferred aspect, the container body may have an aggregate inlet serving as the inlet for taking out and placing the wet tissues, and a body cover portion capable of opening and closing the aggregate inlet, the body cover portion may be provided on the bottom surface of the wet tissue storage container, the groove portion may be provided on the body cover portion, and the fragile portion may be provided in a region overlapping with the groove portion of the body cover portion. According to this aspect, since the groove is provided in the bottom surface, the groove is not visible in the state where the storage container is provided, and the groove can be provided without impairing the external appearance.

According to a preferred aspect, the body cover may include: a setting unit which is provided on a surface facing the inside of the container body and on which the wet tissue aggregate is placed; and a guide portion that guides a position of a side surface of the wet tissue aggregate on the installation portion, wherein a recessed portion that is recessed from an outside of the container body toward an inside of the container body is provided on a back surface of the guide portion, and the groove portion is constituted by the recessed portion. According to this aspect, the recessed portion in the guide portion that guides the position of the side surface of the wet tissue aggregate constitutes the groove portion. Compared with the mode of arranging the guide part and the groove part respectively, the volume of the whole accommodating container can be reduced, and the wet tissue accommodating container can be compact.

According to a preferred embodiment, the main body cover has a rectangular shape in plan view, and has 4 corners and sides connecting the corners, the guide portion is disposed at the corners, the main body cover has an auxiliary guide portion which is connected to the guide portion and extends along the sides of the main body cover, and guides a position of a side surface of the wet tissue aggregate on the installation portion, an auxiliary recess portion recessed from an outer side of the container main body toward an inner side of the container main body is provided on a rear surface of the auxiliary guide portion, the groove portion is formed by the recess portion and the auxiliary recess portion, and the fragile portion overlaps with a region spanning the recess portion and the auxiliary recess portion. According to this aspect, since the recess and the frangible portion are provided at the corner of the body cover, the user can apply a force to the corner of the body cover to unseal the package piece at the time of unsealing. The corner portion is easily noticeable in the body cover portion, and a user can easily operate the frangible portion to unseal. Further, after the package sheet is once unsealed at a position corresponding to the recessed portion, a force can be applied from the recessed portion along the auxiliary recessed portion, and the unsealing portion can be continuously formed along the side edge of the body cover portion. By continuously forming the opening portion, the opening portion of the package sheet becomes large, and the package sheet is more easily detached.

According to a preferred mode, the depth of the recess may be deeper than the depth of the auxiliary recess. According to this aspect, since the depth of the concave portion is deep, the packaging sheet overlapping the concave portion is easily broken when a force is applied to the concave portion. The unsealing portion formed in the recess can be expanded along the auxiliary recess.

According to a preferred embodiment, the groove portion and the fragile portion may extend in a first direction in a plan view, and a depth of the groove portion may be longer than a length of the groove portion in a second direction orthogonal to the first direction. According to this aspect, when a force is applied to the fragile portion, the depth of the groove portion is deeper than the length of the groove portion (width of the groove portion) in the second direction orthogonal to the direction in which the groove portion extends. Since the depth of the groove portion is relatively deep, a force is easily applied in the depth direction of the groove portion. Since the depth direction of the groove portion is along the thickness direction of the package sheet, the package sheet is easily broken by applying a shearing force to the package sheet by applying a force to the depth direction of the groove portion.

According to a preferred embodiment, the fragile portion may be formed of an aggregate of through holes penetrating the package sheet, and the diameter of the through holes on the outer surface of the package sheet may be larger than the diameter of the through holes on the inner surface of the package sheet. According to this aspect, when the package sheet is broken, a force is applied from the outer surface side of the package sheet. Since the diameter of the through hole of the outer surface of the package sheet is large, the package sheet is more likely to break when a force is applied from the outer surface side of the package sheet.

In a preferred embodiment, the package sheet may have a reinforcing portion which is less likely to be broken than the surrounding, and the reinforcing portion may be provided along the fragile portion. According to this aspect, since the reinforcing portion is provided along the fragile portion, the fragile portion is more easily broken at the time of unsealing due to the poor rigidity between the reinforcing portion and the fragile portion.

(2) Overall outline structure of wet tissue container

Hereinafter, a wet tissue storage container (hereinafter referred to as a storage container) according to an embodiment will be described with reference to the drawings. In the description of the drawings below, the same or similar parts are denoted by the same or similar reference numerals. It should be noted, however, that the drawings are schematic, and the ratio of the dimensions and the like are different from reality. Therefore, specific dimensions and the like should be determined with reference to the following description. In addition, the drawings may include portions having different dimensional relationships and ratios.

Fig. 1 is a perspective view of the top surface side of the housing container 1 according to the embodiment. Fig. 2 is a perspective view of the storage container 1 from the bottom side. Fig. 3 is an exploded perspective view of the container body 10 and the lid 30 constituting the storage container 1. Fig. 4 is a bottom view of the container body. Fig. 5 is a cross-sectional view of the wet tissue receiving container taken along the line A-A shown in fig. 4. Fig. 6 is a cross-sectional view of the wet tissue storage container taken along the line B-B shown in fig. 4. The storage container 1 includes a container body 10, a lid 30, and a package sheet 50. The container body 10 has a substantially rectangular parallelepiped shape, and includes top and bottom surfaces 11 and 12 facing each other, front and rear surfaces 13 and 14 facing each other, and left and right side surfaces 15 and 16 facing each other. The container body 10 accommodates a wet tissue aggregate 80 (see fig. 5 and 6), and has a take-out opening 17 serving as a take-out opening for each wet tissue when used. The take-out opening 17 is provided on the top surface 11 and is opened and closed by the cover 30. Thus, the top surface 11 constitutes an open cover. The storage container 1 includes: the vertical direction D1 extends in the vertical direction in a state where the top surface 11 is disposed upward; and a lateral direction D2 extending in the left-right direction when viewed from the front and a longitudinal direction D3 extending in the depth direction when viewed from the front.

The container body 10 includes an aggregate inlet 21 serving as an inlet for taking out and placing the wet tissue aggregate 80, and a body cover 22 capable of opening and closing the aggregate inlet 21. The body cover 22 may be provided on the bottom 12 of the container body 10. The aggregate inlet 21 is an opening for taking out the aggregate 80 of wet tissues, and is different from the take-out opening 17 which is an outlet for 1 wet tissue to 1 wet tissue when used. The aggregate inlet 21 is formed by an opening edge surrounded by the left side surface 15, the right side surface 16, the front surface 13, and the back surface 14. When the user puts the wet tissue assembly 80 into the storage container and replaces the wet tissue assembly 80, the body cover 22 is separated to form the assembly inlet 21. Fig. 3 shows the body cover 22 separated. After the wet tissue assembly 80 is stored in the storage container 1, the main body cover 22 is again attached.

The body cover 22 may have a setting portion 23 and a guide portion 24. The installation portion 23 is provided on the inner side of the container body 10, that is, on the surface of the wet tissue assembly 80 facing the storage space. The setting unit 23 is a portion on which the wet tissue assembly 80 is placed. The installation portion 23 is centrally installed in a plan view of the main body cover 22. The guide portion 24 is recessed from the outside of the container body 10 toward the inside of the container body 10. As shown in fig. 3, the guide portion 24 stands on the side of the installation portion 23 toward the inside of the storage container 1 than the installation portion 23. The guide portion 24 abuts against the side surface of the wet tissue assembly 80 on the setting portion 23, and guides the position of the side surface of the wet tissue assembly 80. More specifically, the guide portion 24 has both a function of supporting the positioning of the wet tissue assembly 80 when the wet tissue assembly is placed on the placement portion 23 and a function of suppressing the positional displacement of the wet tissue assembly 80 placed on the placement portion 23. The body cover 22 is rectangular in plan view, and has 4 corners 25 and side edges 26 connecting the corners to each other. The guide portion 24 is provided at the corner portion 25. The guide portion 24 may be provided at least one corner 25 of the 4 corners. The guide portions 24 of the present embodiment are provided at the 4 corner portions 25, respectively.

The body cover 22 may have an auxiliary guide 27 connected to the guide 24 and extending along the side 26, and guiding the position of the side of the wet tissue assembly 80 on the setting part 23. The auxiliary guide 27 may connect the guide portions 24 to each other. The guide portions 24 of the present embodiment are disposed at positions corresponding to the 4 corner portions 25, respectively, and the auxiliary guide portions 27 have portions extending in the longitudinal direction D3 and portions extending in the lateral direction D2, respectively. In a state where the wet tissue assembly 80 is placed on the setting unit 23, the auxiliary guide 27 is disposed along the side edge of the wet tissue assembly 80, and the guide 24 is disposed at a position corresponding to the corner of the wet tissue assembly 80.

The lid body 30 can open and close the take-out opening 17 of the container body 10. The lid 30 is configured to be openable and closable with respect to the take-out opening 17 via the hinge 18. The container body 10 and the lid 30 of the present embodiment are integrated via the hinge 18. In other embodiments, the lid 30 may be detachable from the container body 10. In the container body 10, a pressing lock/open mechanism 19 is disposed in a region facing the hinge 18 through the take-out opening 17, in which the lid 30 in a closed state is engaged and pressed to be able to disengage the lid 30 from the container body 10. The surface of the push lock/unlock mechanism 19 constitutes an operation button for performing the opening/closing operation of the lid 30.

The package sheet 50 includes the container body 10 and the lid body 30 in a state before use. The packaging sheet may be formed to include the whole of the container body 10 and the lid body 30, or may be formed to cover a part of the container body 10 and the lid body 30. When the user uses the wet tissue, the package sheet 50 is opened, and at least the cover 30 is exposed, the cover 30 is opened and closed, and the wet tissue is taken out. The wrapper sheet 50 may be constructed of a film. The material of the film is not particularly limited, and may be, for example, a material obtained by mixing polyethylene with polypropylene.

The storage container 1 of the present embodiment is configured to enable easy and smooth opening operation of the package sheet 50. Next, a structure for improving the unsealing operation of the package sheet 50 will be described in detail. The package sheet 50 has a frangible portion 55 which is more likely to be broken than the surrounding. The fragile portion 55 is not limited as long as it is configured to be more easily broken than the surrounding. For example, the through holes such as needle holes may be arranged in a single row, or the through holes may be arranged in a plurality of rows, or may be a portion which extends beyond the periphery and has reduced strength. As shown in fig. 7, the fragile portion 55 of the present embodiment is constituted by an aggregate of through holes 56 in which through holes 56 aligned in a row along the longitudinal direction D3 are arranged in a plurality of rows at intervals in the lateral direction D2. The fragile portion 55 is disposed over the entire lateral direction D2 of the bottom surface 12, and may be disposed in a part of the longitudinal direction D3 of the bottom surface 12. The length of the longitudinal direction D3 of the fragile portion 55 may be 4mm or more. At least one of the container body 10 and the lid 30 is provided with a groove 70 recessed toward the inside of the storage container 1. The groove 70 may be provided only on the container body 10, only on the lid 30, both on the container body 10 and the lid 30, or on the boundary between the container body 10 and the lid 30.

At least a part of the fragile portion 55 is provided in a region overlapping with the groove portion 70. As shown in fig. 5, the fragile portion 55 of the present embodiment overlaps with the groove portion 70 formed in the body cover portion 22. The fragile portion 55 is disposed so as to cover the groove portion 70. The package sheet 50 can be opened via the frangible portion 55 of the package sheet 50. At this time, since the fragile portion 55 overlaps with the groove portion 70, a space of the groove portion 70 is disposed inside the storage container 1 as compared with the fragile portion 55. Therefore, the force for opening the package sheet 50 is easily applied to the frangible portion 55. Further, since the space of the groove is disposed inside the fragile portion 55, a finger or the like can be inserted at the time of opening, and a force in the shearing direction can be easily applied to the package sheet 50. Therefore, the package sheet 50 can be easily broken, and the operation of unsealing the storage container 1 can be easily performed.

The fragile portion 55 may overlap the groove portion 70 in a region overlapping a surface other than the opening cover (surface other than the top surface) of the container body 10. The opening surface may be any one of 5 surfaces other than the opening surface when the opening surface is provided on one surface, or may be any one of the surfaces other than the surface when the opening surface is provided across a plurality of surfaces. When a force is applied to the frangible portion 55, the force does not act on the opening cover, and the force is applied to a surface other than the opening surface. In general, an operation button for operating the opening and closing of the cover body 30, such as the push lock/open mechanism 19, is disposed on the opening cover. Breakage of an operation button of an opening cover due to a force applied at the time of opening can be suppressed.

The groove 70 may be provided in the body cover 22. The frangible portion 55 may be provided in an area overlapping the groove portion 70 of the body cover 22. Since the groove 70 is provided in the body cover 22 provided with the bottom surface, the groove 70 is not visible in the state where the storage container 1 is provided, and the groove can be provided without impairing the external appearance. The main body cover 22 is a portion that is operated when taking out and putting in the wet tissue aggregate. By providing the groove 70 in the body cover 22, a finger can be applied to the groove 70 during the opening and closing operation of the body cover 22, and the operability during the opening and closing operation of the body cover 22 can be improved. That is, the groove 70 of the body cover 22 has both a function of improving operability when opening and closing the body cover 22 and a function of improving operability when opening the package sheet 50.

The rear surface of the guide portion 24 has a recess portion 24X recessed from the outside of the container body 10 toward the inside of the container body 10. The recessed portion of the recessed portion 24X constitutes a portion of the guide portion 24 protruding inward of the container body. That is, the concave portion 24X and the guide portion 24 overlap in the thickness direction. The groove 70 may be constituted by the recess 24X of the guide portion 24. The groove 70 may be formed only by the recess 24X, that is, may be provided only in the corner 25. The recess 24X in the guide portion for guiding the position of the side surface of the wet tissue assembly 80 constitutes the groove 70. By configuring the groove portion 70 by the guide portion 24 for guiding the position of the wet tissue assembly 80, the volume of the entire storage container 1 can be reduced and the storage container 1 can be made compact as compared with a case where the guide portion 24 and the groove portion 70 are provided. The guide portion 24 is in contact with the side surface of the wet tissue assembly 80, and is not disposed between the setting portion 23 and the wet tissue assembly 80. Therefore, the guide portion 24 does not raise the wet tissue assembly 80 on the setting portion 23. The height of the storage container 1 can be suppressed from increasing, and the storage container 1 can be made compact, as compared with the configuration in which the guide portion 24 raises the assembly 80 of wet tissues on the setting portion 23.

The auxiliary guide portion 27 has an auxiliary recess portion 27X recessed from the outside of the container body 10 toward the inside of the container body 10. The recessed portion in the auxiliary recessed portion 27X constitutes a portion of the auxiliary guide portion 27 protruding inward of the container body. That is, the auxiliary recessed portion 27X and the auxiliary guide portion 27 overlap in the thickness direction. The groove 70 may be constituted by the recess 24X and the auxiliary recess 27X. The frangible portion 55 may overlap with the region spanning the recess 24X and the auxiliary recess 27X. Since the recess 24X and the frangible portion 55 are provided at the corner 25 of the body cover 22, the user can open the package sheet 50 by applying a force to the corner of the body cover 22 at the time of opening. The corner 25 is easily noticeable in the body cover 22, and the user can easily open the frangible portion 55 by manipulating it. After temporarily unsealing the package sheet 50 at a position corresponding to the recess 24X, a force can be applied from the recess 24X along the auxiliary recess 27X to continuously form an unsealed portion of the package sheet 50 along the side 26 of the body cover 22. By continuously forming the opening portion, the opening portion of the package sheet 50 is easily increased, and the package sheet 50 is easily peeled from the container body. In addition, the depth 24D of the recess 24X may be deeper than the depth 27D of the auxiliary recess 27X. Since the depth 24D of the recess 24X is large, the package sheet 50 overlapping the recess 24X is easily broken when a force is applied to the recess 24X. The unsealing portion formed in the recess 24X can be expanded along the auxiliary recess 27X. The width of the recess 24X may be longer than the width 27W of the auxiliary recess 27X. The user can easily break the package sheet through the concave portion 24X. Once the package sheet is broken, the finger does not need to be pushed deep, and therefore, even if the width 27W of the auxiliary recess 27X is short, the opening portion of the package sheet 50 can be easily increased. Ribs 24Y may be provided in the recessed portions 24X. The rib 24Y is a wall that stands from the bottom surface of the recess 24X toward the outside of the storage container 1. By providing the rib 24Y in the concave portion 24X, the depth of the portion where the rib 24Y is provided becomes shallow, and when a finger is inserted at the time of unsealing the package sheet, the finger can be prevented from excessively entering the concave portion 24X.

The groove 70 and the fragile portion 55 extend in the first direction in a plan view, and the depth of the groove 70 may be longer than the length of the groove 70 in the second direction orthogonal to the first direction. In the present embodiment, the region where the recess 24X and the auxiliary recess 27X are combined and the fragile portion 55 extend in the lateral direction D2. The transverse direction D2 of the present embodiment constitutes a first direction, and the longitudinal direction D3 constitutes a second direction. When a force is applied to the fragile portion 55, the depth of the groove 70 is deeper than the length of the groove (width of the groove) in the second direction orthogonal to the direction in which the groove 70 extends. Since the depth of the groove 70 is relatively large, a force is easily applied in the depth direction of the groove 70. Since the depth direction of the groove 70 is along the thickness direction of the package sheet 50, the package sheet 50 is easily broken by applying a shearing force to the package sheet 50 by applying a force to the depth direction of the groove 70. In the embodiment in which the depth and width of the groove portion are changed, the depth of the groove portion may be made longer than the width of the groove portion at any position.

Fig. 7 (a) is an enlarged view of the packaging sheet 50 of the portion C shown in fig. 2, and fig. 7 (b) is a sectional view taken along the line D-D shown in fig. 7 (a). The frangible portion 55 may be constituted by an aggregate of through holes 56 penetrating the package sheet. The diameter 56Y of the through-holes 56 of the outer surface of the package sheet may be larger than the diameter 56Z of the through-holes 56 of the inner surface of the package sheet 50. Upon breaking the package 50, a force is applied from the outer surface side of the package. Since the diameter 56Y of the through-hole of the outer surface of the package sheet is large, the package sheet 50 is more likely to break when a force is applied from the outer surface side of the package sheet 50. Further, since the diameter 56Y of the through hole on the outer surface side of the package sheet 50 is large, the through hole 56 is easily noticeable from the outside of the storage container 1. The user easily notices the existence of the through hole 56 when unsealing. The length of the transverse direction D2 of the through-hole 56 of the present embodiment is longer than the length of the longitudinal direction D3 of the through-hole 56. Therefore, the package sheet is easily broken continuously in the lateral direction D2. In the modification, the length of the longitudinal direction D3 of the through hole 56 may be longer than the length of the transverse direction D2 of the through hole 56.

As shown in fig. 2, the package sheet 50 may have a reinforcing portion 57 which is more difficult to break than the surrounding. The reinforcing portion 57 may be provided along the fragile portion 55. Since the reinforcing portion 57 is provided along the fragile portion 55, the fragile portion 55 is more easily broken at the time of unsealing due to the poor rigidity between the reinforcing portion 57 and the fragile portion 55. The reinforcing portion 57 of the present embodiment is provided in a region overlapping the side edge intersecting the bottom surface 12 and the front surface 13 of the container body 10, and extends in the lateral direction D2 as in the frangible portion 55. The reinforcing portion 57 and the fragile portion 55 may be adjacent to each other in the longitudinal direction D3 or may be separated from each other in the longitudinal direction D3 as in the present embodiment. The reinforcing portion 57 may be a portion having higher rigidity than the surrounding area, and may be a portion that is hardened than the surrounding area by being heated, for example.

The packaging method of the package sheet in the storage container 1 can be a known method. Next, an example of a packaging method of the packaging sheet will be described. One package sheet is abutted against the surface of the housing container 1 on the lid 30 side. In the package sheet 50, air holes for discharging air in a step described later are formed in advance. Next, the package sheet 50 is folded along the side of the receiving container extending in the lateral direction D2. The end edges of the package sheet 50 extending in the lateral direction D2 are joined to each other on the bottom surface (body cover) of the housing container 1. When the package sheets are joined to each other, the remaining portion (portion protruding from the joined portion) is discarded. Next, the package sheets 50 are joined to each other along a line extending perpendicular (longitudinally) to the package sheets 50 along the side edges of the receiving container 1 extending in the transverse direction. That is, the package pieces 50 are joined to each other on both sides of the housing container 1 in the lateral direction. Next, the storage container 1 is passed through the heat source passage. The package sheet 50 is shrunk by heat, and air between the package sheet 50 and the storage container 1 is discharged in advance through air holes formed in the package sheet 50. In such a storage container 1, as shown in fig. 1, a pattern 59 that overlaps with an opening button in a packaged state may be provided on a packaging sheet, and the fragile portion 55 and the groove portion 70 may be overlapped by aligning the opening button with the pattern. The pattern 59 may be a display (e.g., text of OPEN) indicating the position of the opening button. According to this configuration, the fragile portion 55 can be arranged at an appropriate position by aligning the opening button with the pattern without aligning the fragile portion 55 with the groove portion 70.

The present invention has been described in detail using the embodiments described above, but it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modifications and variations without departing from the spirit and scope of the present invention as defined in the appended claims. Accordingly, the description of the present invention is intended to be illustrative, and not limiting.
