Disclosure of Invention

When the user uses the wet tissue, the user breaks the packaging sheet and removes the packaging sheet, and then opens and closes the storage container to use the wet tissue. In this case, in the resinous storage container, the packaging sheet such as a film is likely to be in close contact with the container, and the user may be difficult to break the packaging sheet. Further, depending on the user, the force is applied to the packaging sheet to tear or stretch the packaging sheet and break the packaging sheet, and therefore, unnecessary force may be applied to the opening operation. Further, since the packaging sheet is broken by a sharp tool depending on the user, there are problems that time and effort are required for preparing the tool, and the storage container is damaged by the tool. Further, depending on the user, a force may be applied to the lid body for opening and closing the lid body in the vicinity of the operation button, and the operation button may be broken.

The present invention has been made in view of the above problems, and an object thereof is to provide a wet tissue storage container that can easily and smoothly perform an unsealing operation.

A wet tissue storage container according to one aspect includes: a container body which contains an aggregate 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 removal 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 lid body is provided with a groove portion recessed toward the inside of the storage container. The packaging sheet has a weakened portion which is more easily broken than the periphery. At least a part of the fragile portion is provided in a region overlapping with the groove portion.

Detailed Description

(1) Brief description of the embodiments

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

A wet tissue storage container according to one aspect includes: a container body which contains an aggregate 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 removal 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 lid body is provided with a groove portion recessed toward the inside of the storage container. The packaging sheet has a weakened portion which is more easily broken than the periphery. At least a part of the fragile portion is provided in a region overlapping with the groove portion. According to this aspect, the packaging sheet can be unsealed through the fragile portion of the packaging sheet. At this time, since the weak portion overlaps the groove portion, a space of the groove portion is disposed inside the weak portion. Therefore, a force for opening the packaging sheet is easily applied to the fragile portion, the packaging sheet can be easily broken, and the opening operation of the storage container can be easily performed.

According to a preferred aspect, the container body may have a front cover to which the lid is attached, and the weak portion may overlap the groove portion in a region overlapping a surface of the container body other than the front cover. According to this aspect, when a force is applied to the fragile portion, the force is not applied to the opening cover, and the force is applied to a surface other than the opening cover. Therefore, it is possible to suppress damage to the opening/closing member such as the operation button for opening the cover due to the force applied at the time of opening the cover.

According to a preferred aspect, the container body may have an aggregate entrance which serves as a takeout and introduction port of the aggregate of the wet tissues, and a body cover which is openable and closable with respect to the aggregate entrance, the body cover may be provided on a bottom surface of the wet tissue storage container, the groove may be provided on the body cover, and the fragile portion may be provided in a region overlapping with the groove of the body cover. According to this aspect, since the groove portion is provided in the bottom surface, the groove portion is not visible when the storage container is installed, and the groove portion can be provided without impairing the appearance.

According to a preferred aspect, the body cover may include: an installation part which is arranged on the surface facing the inner side of the container body and is used for placing the aggregate of the wet tissues; and a guide portion that guides a position of a side surface of the aggregate of the wet tissues on the installation portion, wherein a recessed portion that is recessed from an outer side of the container body toward an inner side of the container body is provided on a back surface of the guide portion, and the groove portion is formed 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 aggregate of the wet tissues forms the groove portion. Compared with the mode of respectively providing the guide part and the groove part, the capacity of the whole storage container can be reduced, and the wet tissue storage container can be compact.

According to a preferred aspect, the body cover portion may have a rectangular shape in plan view, 4 corners and sides connecting the corners to each other, the guide portion may be disposed at the corners, the body cover portion may have an auxiliary guide portion that extends along the sides of the body cover portion and is continuous with the guide portion, and guides a position of a side surface of the aggregate of wet tissues on the installation portion, an auxiliary recess portion that is recessed from an outer side of the container body toward an inner side of the container body may be provided on a back surface of the auxiliary guide portion, the groove portion may be formed by the recess portion and the auxiliary recess portion, and the weak portion may overlap a region that spans the recess portion and the auxiliary recess portion. According to this aspect, since the recessed portion and the fragile portion are provided at the corner portion of the body lid portion, the user can open the packaging sheet by applying a force to the corner portion of the body lid portion at the time of opening the package. The corner portion is easy to see at the main body lid portion, and the user can easily open the opening by manipulating the fragile portion. Further, after the packaging sheet is temporarily opened at a position corresponding to the recessed portion, a force can be applied from the recessed portion along the auxiliary recessed portion, and the opening portion can be continuously formed along the side of the main body lid portion. By continuously forming the opening portion, the opening portion of the packaging sheet becomes large, and the packaging sheet is more easily detached.

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

According to a preferred aspect, 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 in the second direction (the width of the groove portion) 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 packaging sheet, the packaging sheet is easily broken by applying a force to the depth direction of the groove portion and applying a shearing force to the packaging sheet.

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

According to a preferred aspect, the package sheet may have a reinforcing portion that is less likely to be broken than the surrounding portion, 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 difference in rigidity between the reinforcing portion and the fragile portion.

(2) General structure of wet tissue storage 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 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 scale of each dimension and the like are different from those in 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 from each other.

Fig. 1 is a perspective view of the storage container 1 according to the embodiment viewed from the top surface side. Fig. 2 is a perspective view of the storage container 1 as viewed from the bottom surface 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 sectional view of the wet tissue storage container with reference to a section taken along the line a-a shown in fig. 4. Fig. 6 is a sectional view of the wet tissue storage container taken along the section line B-B shown in fig. 4. The storage container 1 includes a container body 10, a lid body 30, and a packaging sheet 50. The container body 10 has a substantially rectangular parallelepiped shape, and has a top surface 11 and a bottom surface 12 facing each other, a front surface 13 and a back surface 14 facing each other, and a left side surface 15 and a right side surface 16 facing each other. The container body 10 accommodates an aggregate 80 of wet tissues (see fig. 5 and 6), and has a take-out opening 17 serving as a take-out port for use of each wet tissue. The removal opening 17 is provided in the top surface 11 and is opened and closed by the lid 30. The top surface 11 thus constitutes an opening cover. The storage container 1 includes: a vertical direction D1 extending in the vertical direction with the top surface 11 disposed facing upward; and a lateral direction D2 extending in the left-right direction when viewed frontally and a longitudinal direction D3 extending in the depth direction when viewed frontally.

The container body 10 has an aggregate entrance 21 serving as a take-in/take-out entrance for the aggregate 80 of wet tissues and a body lid 22 capable of opening and closing the aggregate entrance 21. The body cover 22 may be disposed on the bottom surface 12 of the container body 10. The aggregate inlet 21 is an opening through which the aggregate 80 containing the wet tissues is taken out and put in, and is different from the take-out opening 17 which is a take-out opening for 1 sheet of wet tissues in use. 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 aggregate 80 of wet tissues into the storage container and replaces the aggregate 80 of wet tissues, the body cover 22 is separated to form the aggregate inlet 21. Fig. 3 shows the body cover 22 in a separated state. After the assembly 80 of wet tissues is stored in the storage container 1, the main body cover 22 is attached again.

The body cover portion 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 aggregate 80 facing the storage space. The installation portion 23 is a portion on which the aggregate 80 of wet tissues 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 is erected on the side of the installation portion 23 toward the inside of the storage container 1 with respect to the installation portion 23. The guide portion 24 is in contact with the side surface of the aggregate 80 of wet tissues on the installation portion 23, and guides the position of the side surface of the aggregate 80 of wet tissues. More specifically, the guide portion 24 has both a function of supporting the positioning of the aggregate 80 of wet tissues when the aggregate of wet tissues is disposed in the installation portion 23 and a function of suppressing the positional deviation of the aggregate 80 of wet tissues disposed in the installation portion 23. The body cover 22 is rectangular in plan view, and has 4 corners 25 and sides 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 in at least one corner portion 25 of the 4 corner portions. The guide portions 24 of the present embodiment are provided at the 4 corner portions 25, respectively.

The body cover part 22 may have an auxiliary guide part 27 connected to the guide part 24 and extending along the side edge 26, and guiding the position of the side surface of the aggregate 80 of wet tissues on the arrangement part 23. The auxiliary guide portions 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 each have a portion extending in the longitudinal direction D3 and a portion extending in the lateral direction D2. In a state where the aggregate 80 of wet tissues is placed on the installation portion 23, the auxiliary guide portion 27 is disposed along the side of the aggregate 80 of wet tissues, and the guide portion 24 is disposed at a position corresponding to the corner of the aggregate 80 of wet tissues.

The lid 30 can open and close the removal opening 17 of the container main body 10. The lid 30 is configured to be openable and closable with respect to the removal 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 another embodiment, the lid 30 may be detachable from the container body 10. In the container main body 10, a press lock/open mechanism 19 is disposed in a region facing the hinge portion 18 through the removal opening 17, the press lock/open mechanism being capable of engaging and disengaging the lid 30 with respect to the container main body 10 by engaging and pressing the lid 30 in a closed state. The surface of the push lock/open mechanism 19 constitutes an operation button for performing an opening and closing operation of the lid body 30.

The packaging sheet 50 encloses the container body 10 and the lid 30 before use. The packaging sheet may enclose the entirety of the container body 10 and the lid body 30 or may enclose a part of the container body 10 and the lid body 30. When the user uses the wet tissue, the user opens the packaging sheet 50, opens and closes the lid 30 with at least the lid 30 exposed, and takes out the wet tissue. The packaging sheet 50 may be composed of a film. The material of the film is not particularly limited, and may be, for example, a mixture of polypropylene and polyethylene.

The storage container 1 of the present embodiment is configured to be able to easily and smoothly perform an opening operation, that is, an opening operation of the packaging sheet 50. Next, a structure for improving the opening operability of the packaging sheet 50 will be described in detail. The packaging sheet 50 has a fragile portion 55 which is more easily broken than the periphery. The fragile portion 55 is not limited in its structure as long as it is easily broken than the surroundings. For example, the assembly may be one in which through-holes such as needle holes are arranged in a row, one in which through-holes are arranged in a plurality of rows, or a portion extending from the periphery and having a lower strength. As shown in fig. 7, the fragile portion 55 of the present embodiment is formed of an aggregate of through-holes 56 arranged in a plurality of rows at intervals in the lateral direction D2 along the through-holes 56 aligned in a row in the vertical direction D3. The fragile portion 55 is disposed over the entire width 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 fragile portion 55 in the longitudinal direction D3 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 in the container body 10, only in the lid 30, in both the container body 10 and the lid 30, or in 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 the groove portion 70 formed in the main body cover portion 22. The weak portion 55 is disposed so as to cover the groove portion 70. The packaging sheet 50 can be unsealed through the fragile portion 55 of the packaging sheet 50. At this time, since the weak portion 55 overlaps the groove portion 70, a space of the groove portion 70 is arranged inside the storage container 1 than the weak portion 55. Therefore, a force for opening the packaging sheet 50 is easily applied to the fragile portion 55. Further, since the space of the groove portion is disposed inside the fragile portion 55, a finger or the like can be inserted at the time of opening the package sheet 50, and a force in the shearing direction is easily applied. Therefore, the packaging sheet 50 can be easily broken, and the operation of opening the storage container 1 can be easily performed.

The weak portion 55 may overlap the groove portion 70 in a region overlapping a surface other than the opening surface (a surface other than the top surface) of the container body 10. When the opening surface is provided on one surface, the opening surface may be any one of 5 surfaces other than the opening surface, and when the opening surface is provided over a plurality of surfaces, the opening surface may be any one other than the plurality of surfaces. When a force is applied to the fragile portion 55, the force is not applied to the open cover, and the force is applied to the face other than the open cover. Normally, an operation button for operating opening and closing of the lid body 30, such as the push lock/open mechanism 19, is disposed on the open cover. The operation button of the opening cover can be prevented from being damaged by the force applied when opening the cover.

The groove 70 may be provided in the body cover 22. The weak portion 55 may be provided in a region overlapping with 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 a state where the storage container 1 is provided, and the groove can be provided without impairing the appearance. The main body cover 22 is a part that is operated when the assembly of wet tissues is taken out and put in. By providing the groove 70 in the main body cover 22, a finger can be applied to the groove 70 when opening and closing the main body cover 22, and operability when opening and closing the main body cover 22 can be improved. That is, the groove portion 70 of the main body lid portion 22 has both a function of improving operability when opening and closing the main body lid portion 22 and a function of improving operability when opening the packaging sheet 50.

A recessed portion 24X recessed from the outside of the container body 10 toward the inside of the container body 10 is provided on the back surface of the guide portion 24. The recessed portion in the recessed portion 24X constitutes a portion of the guide portion 24 that protrudes toward the inside of the container body. That is, the recessed portion 24X and the guide portion 24 overlap in the thickness direction. The groove portion 70 may be constituted by the recessed portion 24X of the guide portion 24. The groove portion 70 may be formed only by the recessed portion 24X, that is, only in the corner portion 25. The recessed portions 24X in the guide portion that guide the positions of the side surfaces of the aggregate 80 of wet tissues constitute the groove portions 70. Since the groove portion 70 is formed by the guide portion 24 that guides the position of the wet tissue assembly 80, the volume of the entire storage container 1 can be reduced as compared with a case where the guide portion 24 and the groove portion 70 are separately provided, and the storage container 1 can be made compact. The guide portion 24 is in contact with a side surface of the aggregate of wet tissues 80, and is not disposed between the installation portion 23 and the aggregate of wet tissues 80. Therefore, the guide portion 24 does not raise the aggregate 80 of the wet tissues on the setting portion 23. Compared with the structure in which the wet tissue assembly 80 on the installation portion 23 is raised by the guide portion 24, the height of the storage container 1 can be suppressed from increasing, and the storage container 1 can be made compact.

The auxiliary guide portion 27 has an auxiliary recessed 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 that protrudes toward the inside of the container body. That is, the auxiliary recessed portion 27X and the auxiliary guide portion 27 overlap in the thickness direction. The groove portion 70 may be constituted by the recessed portion 24X and the auxiliary recessed portion 27X. The fragile portion 55 may overlap with an area spanning the recess portion 24X and the auxiliary recess portion 27X. Since the recessed portion 24X and the fragile portion 55 are provided at the corner portion 25 of the main body lid portion 22, the user can open the package sheet 50 by applying a force to the corner portion of the main body lid portion 22 at the time of opening. The corner portion 25 is noticeable in the main body lid portion 22, and the user can easily open the frangible portion 55. After the packaging sheet 50 is temporarily opened at a position corresponding to the recessed portion 24X, a force is applied from the recessed portion 24X along the auxiliary recessed portion 27X, and an opening portion of the packaging sheet 50 can be continuously formed along the side edge 26 of the main body lid portion 22. By forming the opening portion continuously, the opening portion of the packaging sheet 50 is easily enlarged, and the packaging 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 recessed portion 24X is large, the package sheet 50 overlapping the recessed portion 24X is easily broken when a force is applied to the recessed portion 24X. The opening portion formed in the recessed portion 24X can be expanded along the auxiliary recessed portion 27X. The width of the recessed portion 24X may be longer than the width 27W of the auxiliary recessed portion 27X. The user easily breaks the packaging sheet through the recess 24X. Since it is not necessary to deeply insert a finger after the packaging sheet is once broken, the opening portion of the packaging sheet 50 can be easily enlarged even if the width 27W of the auxiliary recessed portion 27X is short. Ribs 24Y may be provided in the recessed portions 24X. The rib 24Y is a wall erected from the bottom surface of the recessed portion 24X toward the outside of the storage container 1. By providing the rib 24Y in the recessed 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 opening the packaging sheet, the finger can be prevented from excessively entering the recessed portion 24X.

The groove portion 70 and the fragile portion 55 extend in a first direction in a plan view, and the depth of the groove portion 70 may be longer than the length of the groove portion 70 in a second direction orthogonal to the first direction. In the present embodiment, the region where the recessed portion 24X and the auxiliary recessed portion 27X are combined and the fragile portion 55 extend in the lateral direction D2. The lateral 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 portion 70 is deeper than the length of the groove portion in the second direction (the width of the groove portion) orthogonal to the direction in which the groove portion 70 extends. Since the depth of the groove 70 is relatively deep, a force is easily applied in the depth direction of the groove 70. Since the depth direction of the groove portion 70 is along the thickness direction of the packaging sheet 50, a force is applied to the depth direction of the groove portion 70 to apply a shearing force to the packaging sheet 50, thereby easily breaking the packaging sheet 50. In the embodiment in which the depth and width of the groove are changed as in the present embodiment, the depth of the groove may be made longer than the width of the groove at any position.

Fig. 7(a) is an enlarged view of the packaging sheet 50 at 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 fragile portion 55 may be formed of an aggregate of through-holes 56 penetrating the packaging sheet. The diameter 56Y of the through-hole 56 in the outer surface of the packaging sheet may be larger than the diameter 56Z of the through-hole 56 in the inner surface of the packaging sheet 50. When the packaging sheet 50 is broken, a force is applied from the outer surface side of the packaging sheet. Since the diameter 56Y of the through hole in the outer surface of the packaging sheet is large, the packaging sheet 50 is more likely to be broken when a force is applied from the outer surface side of the packaging sheet 50. Further, since the diameter 56Y of the through-hole on the outer surface side of the packaging sheet 50 is large, the through-hole 56 is easily noticeable from the outside of the storage container 1. The user can easily notice the presence of the through-hole 56 when unsealing. The length of the through-hole 56 in the lateral direction D2 is longer than the length of the through-hole 56 in the longitudinal direction D3. It is therefore easy to continuously break the wrapping sheet in the transverse direction D2. In the modification, the length of the through-hole 56 in the longitudinal direction D3 may be longer than the length of the through-hole 56 in the lateral direction D2.

As shown in fig. 2, the packaging sheet 50 may have a reinforcing portion 57 that is less likely to be broken than the surroundings. The reinforcement 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 opening by the difference in 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 with a side edge intersecting the bottom surface 12 and the front surface 13 of the container body 10, and extends in the lateral direction D2 in the same manner as the fragile 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 portion, and may be a portion hardened by being heated than the surrounding portion, for example.

A known method can be applied to the packaging method of the packaging sheet in the storage container 1. Next, an example of a packaging method of the packaging sheet will be described. One packaging sheet is brought into contact with the surface of the storage container 1 on the lid 30 side. In the packaging sheet 50, air holes for discharging air in a process described later are formed in advance. Next, the packaging sheet 50 is folded along the side edge of the storage container extending in the transverse direction D2. The end edges of the packaging sheet 50 extending in the transverse direction D2 are joined to each other on the bottom surface (body lid portion) of the storage container 1. When the packaging sheets are joined to each other, the remaining portion (portion protruding from the joined portion) is discarded. Next, the packaging sheets 50 are joined to each other along a line extending perpendicularly (longitudinally) to the packaging sheets 50 along the side edges of the housing container 1 extending in the transverse direction. That is, the packaging sheets 50 are joined to each other on both lateral sides of the storage container 1. Next, the storage container 1 is passed through the heat source passage. The packaging sheet 50 is shrunk by heat, and air between the packaging sheet 50 and the storage container 1 is discharged in advance through the air holes formed in the packaging sheet 50. In the storage container 1, as shown in fig. 1, a pattern 59 overlapping with the opening button in a packaged state may be provided on the packaging sheet, and the fragile portion 55 and the groove portion 70 may be overlapped by aligning the opening button with the pattern.
