Description

[Technical field]

[0001] The present invention relates to a wet sheet package in which wet sheets such as face masks for packs and wet tissues are packaged in a removable manner, and a method for manufacturing the wet sheet package. [Background technology]

[0002] Conventionally, as disclosed in Patent Document 1, there is a wet sheet package in which a container having an opening on the upper side contains a plurality of wet sheets, and the opening is covered and sealed with a sheet to produce a container-containing wet sheet, which is then contained and sealed in a packaging bag. Generally, in this wet sheet package, a gusset bag is used as the packaging bag, and the container that contains the wet sheets is formed in an upside-down quadrangular pyramid shape that is wider at the top than at the bottom. As a result, a large gap is formed between the gusset bag and the lower part of the side of the container, causing the lower part of the wet sheet package to deform into an upside-down quadrangular pyramid shape, or causing unevenness or wrinkles at the lower part.

[0003] However, since it is desirable for the wet sheet package to be formed in a rectangular parallelepiped shape from the viewpoints of ease of packing in a box for transport, stability, space saving, and good appearance as a product, conventionally, in order to form the wet sheet package into a rectangular parallelepiped shape, a rectangular pad folded into a U-shape is attached to the bottom and left and right sides of the container constituting the containerized wet sheet, and the container is packed in this state in a packaging bag, thereby preventing the lower part of the wet sheet package from deforming into an upside-down quadrangular pyramid shape and preventing unevenness and wrinkles from occurring in the lower part. However, in such a wet sheet package, it is necessary to manufacture the pad and attach the pad to the container, which makes the preparation process for packing the containerized wet sheet into the packaging bag complicated and time-consuming, which is a factor in increasing the manufacturing cost. Moreover, the pad is usually made of synthetic resin, and the use of this pad goes against the trend toward eliminating plastic. Furthermore, the packaging bag has a sealed portion at the end on the side of the container opening and at the end on the opposite side, and the sealed portion is generally folded to fit the side of the packaging bag, and since synthetic resin packaging bags have no rigidity and are easily deformed, the surface of the wet sheet package is somewhat uneven, making it look untidy. Furthermore, when the wet sheet package is picked up, it is relatively easy to deform, which is not preferable from the viewpoint of ease of handling.

[0004] Thus, a wet sheet package as disclosed in Patent Document 2 has been proposed as a wet sheet package that can be manufactured relatively easily without padding, is easy to handle, has a neat appearance, and contributes to eliminating the use of plastic, even if the container for storing wet sheets has an opening on the upper side and slopes the side so that the lower side is narrower than the upper side. As shown in Fig. 13, this wet sheet package comprises containerized wet sheets 2 in which a container 4 having an opening 41 on its upper side contains wet sheets WS and the opening 41 is covered and sealed with a sheet 42, and a packaging box 3 that contains the containerized wet sheets 2. The packaging box 3 is formed in a rectangular parallelepiped shape and is equipped with a cardboard box body 5 having an opening 51 for removing the wet sheets WS at a position corresponding to the opening 41, and a lid 6 provided on the upper surface of the box body 5 that can cover the opening 51.

[0005] In this wet sheet package 1, the lid 6 is composed of a window frame 61 and a lid body 62 attached to the window frame 61 so as to be openable and closable. The window frame 61 has a lower surface facing the upper surface of the box body 5 and has a take-out opening 64 that leads to the opening 51 and through which the wet sheet WS can be taken out. The lid 6 is provided on the upper surface of the box body 5 by bonding the lower surface of the window frame 61 to the upper surface of the box body 5 with an adhesive. The sheet 42 covering the opening 41 has a cutout portion 44 formed by cutting out its central portion and a label lid 45 that covers the cutout portion 44, and the label lid 45 can be repeatedly adhered to and peeled off the upper surface of the sheet 42 covering the opening 41. To take out the wet sheet WS from this wet sheet package, the lid body 62 is opened, the label lid 45 is peeled off, and the fingertips are inserted into the container 4 through the cutout portion 44, the take-out opening 64, and the opening 51, and the wet sheet WS is picked up and pulled out with the fingers.

[0006] [Patent Document 1] Patent Publication No. 2021-024610 [Patent Document 2] Utility Model Registration No. 3241594 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in the conventional wet sheet package described in Patent Document 2, when the wet sheet WS is taken out, the liquid contained in the wet sheet WS, such as beauty essence, adheres to the window frame 61, drips and pools on the upper surface of the sheet 42, spreads around, and adheres to the edge of the opening 51 of the box body 5 and the inner surface of the box body 5. Although the lid 6 and the sheet 42 are made of plastic that does not allow liquids to pass through, the box body 5 is made of paperboard, so that the liquid adhering to the edge of the opening 51 of the box body 5 and the inner surface of the box body 5 seeps into the paperboard and seeps out onto the surface of the box body 5. This results in a poor appearance and a loss of cleanliness, the seeped liquid may inadvertently adhere to clothing, etc., and the mechanical strength of the box body may be reduced.

[0008] The present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to provide a wet sheet package that prevents liquid from seeping out from a packaging box that contains boxed wet sheet even if the box body is made of paperboard.

[0009] According to a first aspect of the present invention, the wet sheet package comprises: a container-containing wet sheet having one or more wet sheets contained in a container having an opening on the upper side, the opening being covered and sealed with a sheet; and a packaging box containing the container-containing wet sheet, the packaging box comprising: a paperboard box body having an opening for removing the wet sheet at a location corresponding to the opening; and a lid attached to the upper surface of the box body and capable of closing the opening, the lid being a wet sheet package comprising: a window frame portion having a lower surface facing the upper surface of the box body and having a removal opening leading to the opening; and a lid body attached to the window frame portion so as to be able to open and close, the window frame portion having a protruding portion in which the edge of the removal opening protrudes from the edge of the opening of the box body toward the center of the opening around the entire circumference of the removal opening, and the protruding portion is bonded with an adhesive to the sheet covering the opening of the container-containing wet sheet around the entire circumference of the removal opening.

[0010] With this configuration, the upper surface of the sheet covering the opening of the container and the edge of the outlet of the window frame are isolated from the box body, so that liquid dripping onto the upper surface of the sheet covering the opening of the container or liquid adhering to the edge of the outlet of the window frame does not reach the box body. Therefore, even if the box body of the packaging box that contains boxed wet wipes is made of paperboard, it is possible to provide a wet wipe package that prevents liquid from seeping out of the box body.

[0011] The wet sheet package according to the second aspect of the present invention can be configured so that the lower surface of the window frame is adhered to the upper surface of the box body with an adhesive.

[0012] With the above-mentioned structure, the lid can be reliably bonded to the box body, and a packaging box having relatively high mechanical strength can be obtained.

[0013] According to the third aspect of the present invention, the wet sheet package has a sealing seal affixed so as to span the upper surface of the lid and the side surface of the box body, and the sealing seal can be configured to have two dashed line-shaped cuts formed horizontally at or near the corner between the upper surface and side surface of the lid, and at or near the corner between the side surface and the upper surface of the box body.

[0014] With the above-mentioned configuration, it is possible to easily determine whether the wet sheet package is unopened or not, and the package can be easily opened in a short time.

[0015] According to a fourth aspect of the present invention, there is provided a method for producing a wet sheet package comprising: a container-packaged wet sheet, which is formed by packaging one or more wet sheets in a container having an opening on the upper side and covering and sealing the opening with a sheet; and a packaging box containing the container-packaged wet sheet, the packaging box comprising a paperboard box body having an opening for removing the wet sheet at a position corresponding to the opening; and a lid attached to the upper surface of the box body and capable of closing the opening, the lid having a window frame portion having a lower surface facing the upper surface of the box body and having a removal opening communicating with the opening; and a lid attached to the window frame portion in an openable and closable manner. The method for manufacturing a wet sheet package consisting of a container-type wet sheet package and a lid body attached to the container-type wet sheet package, wherein the window frame portion has a protruding portion that protrudes from the edge of the opening of the box body toward the center of the opening around the entire circumference of the opening, and the method can be configured to include a lid attachment step of attaching the lid to the upper surface of the box body by pressing the window frame portion, which has adhesive applied to at least the underside of the protruding portion so as to surround the opening, against the sheet covering the opening of the container-type wet sheet contained in the box body of the packaging box when the sheet is sealed around the container-type wet sheet and rises due to the thermal expansion of heated air.

[0016] With this configuration, the window frame is pressed against the sheet that has risen due to the thermal expansion of the air inside the container-packed wet sheet, so that the adhesive applied to the underside of the protruding portion of the window frame can be sufficiently pressed against this raised sheet, and the upper surface of the sheet and the underside of the protruding portion of the window frame can be reliably bonded with a relatively small amount of adhesive, and liquid dripping onto the upper surface of the sheet can be sealed to prevent it from reaching the box body. Furthermore, the lid can be attached to the box body with the container-packed wet sheet stored in the box body, and the attachment of the lid to the box body and the process of preventing liquid from seeping out into the box body are completed simultaneously, simplifying the process of attaching the lid.

Note that the size and positional relationship of the members shown in each drawing may be exaggerated to clarify the explanation. Furthermore, in the following explanation, the same names and symbols indicate the same or similar members, and detailed explanations will be omitted as appropriate. Furthermore, each element constituting the present invention may be configured as a form in which multiple elements are composed of the same member, and one member serves multiple elements, or conversely, the function of one member can be shared by multiple members. First embodiment

[0019] A first embodiment of the present invention will be described with reference to Figs. 1 to 11. The wet sheet package 1 shown in Fig. 1 comprises a container-containing wet sheet 2 shown in Fig. 2 and a packaging box 3 containing the container-containing wet sheet 2. The packaging box 3 comprises a box body 5 made of paperboard formed into a rectangular parallelepiped shape and a lid 6 attached to the upper surface of the box body 5. An opening 51 is formed on the upper surface of the box body 5, and the lid 6 comprises a window frame 61 bonded to the upper surface of the box body 5 and an openable and closable lid body 62, and can close the opening 51 of the box body 5. The lid body 62 has a tab 63 and is attached to the window frame 61 so as to be swingable about an axis (not shown) extending along the edge portion of the lid body 62 opposite to the tab 63.

[0020] 3 is a schematic cross-sectional view of the wet sheet package 1 shown in FIG. 1 cut along a plane parallel to the front of the box body 5, and the containerized wet sheet 2 is configured by storing multiple wet sheets WS in a container 4 having an opening 41 at the top and an inclined side such that the bottom is narrower than the top, and in this state, covering and sealing the opening 41 with an airtight sheet 42. In this embodiment, the wet sheet WS is a face mask containing a beauty serum, and the multiple wet sheets WS stored in the container 4 are each folded and stacked on top of each other. The container 4 is in the shape of an upside-down quadrangular pyramid, has a flange 43 at the top end, and the edge portion of the sheet 42 is fused to the upper surface of the flange 43.

[0021] The sheet 42 has a cutout portion 44 and a label lid 45 that covers the cutout portion 44, and the label lid 45 can be repeatedly attached to and peeled off from the upper surface of the sheet 42. The cutout portion 44 may be half-cut in the sheet 42 so as to surround it, and may be cut off when the wet wipes WS are first removed from the container 4.

[0022] The window frame 61 of the lid 6 has a lower surface facing the upper surface of the box body 5, and has an outlet 64 that communicates with the opening 51. Furthermore, the window frame 61 has a protruding portion 65 in which the edge of the outlet 64 protrudes from the edge of the opening 51 of the box body 5 toward the center of the opening 51 around the entire circumference of the outlet 64. This protruding portion 65 is the part inside the two-dot chain line of the window frame 61 in FIG. 3, and is bonded to the sheet 42 of the container-containing wet wipes 2 around the entire circumference of the outlet 64 with an adhesive G1 applied to the lower surface of the protruding portion 65 so as to surround the outlet 64. Furthermore, in order to ensure that the window frame 61 is attached to the box body 5, the lower surface of the window frame 61 is bonded to the upper surface of the box body 5 with an adhesive G2.

[0023] In the wet sheet package 1, in order to properly store the container-containing wet sheet 2 in the box body 5, a vertical gap is formed between the sheet 42 directly above the flange 43 of the container 4 and the ceiling of the box body 5, and a gap is formed in the front-rear and left-right directions of the box body 5 between the outer edge of the flange 43 and the inner wall of the box body 5. When the container 4 stored in the box body 5 is brought into contact with one inner wall in the front-rear direction of the box body 5, half the size of the gap formed between the other inner wall and the flange 43 of the container 4 is defined as Δa, half the size of the gap formed between the other inner wall in the left-right direction and the flange 43 of the container 4 is defined as Δb, and the gap formed between the upper surface of the sheet 42 directly above the flange 43 of the container 4 stored in the box body 5 and the ceiling is defined as Δh in this embodiment. In other words, the length and width of the storage chamber in the box body 5 are twice Δa and twice Δb larger than the length and width of the upper side of the containerized wet sheet 2, respectively, and the height of the storage chamber in the packaging box is Δh larger than the height from the bottom to the top of the containerized wet sheet. It is preferable that Δa and Δb are each 5 mm or less, and Δh is 5 mm or less. If Δa and Δb are made too large, the container 4 in the box body 5 will not serve to reinforce the box body 5 when the upper corner of the box body 5 is grasped with a hand, and the containerized wet sheet 2 contained in the box body 5 will be unstable. If Δh is made too large, the reinforcing effect of the container 4 on the box body 5 will be weakened, and the box body 5 will be easily deformed, for example, when the upper corner of the box body 5 is held with a hand.

[0024] The box body 5 is formed from a box board 50 shown in Fig. 4. The box board 50 is made up of a top portion 50a, a front portion 50b, a back portion 50c, a right side portion 50d, a left side portion 50e, a bottom portion 50f, and flap portions 50g, 50h, 50i, 50j, 50k, 50l, and 50m, and folds are formed at the boundaries between adjacent portions of these portions. The box board 50 is formed by punching out a paperboard, and the opening 51 is formed by punching out and removing the top portion 50a. In this embodiment, the thickness of the box board 50 is about 0.5 mm.

[0025] To store the containerized wet wipes 2 in the packaging box 3, the right side surface portion 50d and the flap portions 50g, 50i, and 50k of the box body 5 are left open as shown in Fig. 5, the containerized wet wipes 2 are pushed into the box body 5 from these portions, and then the flap portions 50g, 50i, and 50k and the right side surface portion 50d are folded along the fold lines to close the box. The containerized wet wipes 2 may be stored in the packaging box 3 from either the left or right side of the box body 5. In this way, the cut surfaces of the paperboard are not exposed at the front, back, left, and right edges of the top surface of the box body 5, resulting in a neat appearance.

[0026] In the wet sheet package 1, to remove the wet sheet WS from the packaging box, the packaging box 3 is fixed with one hand, and the fingers of the other hand are hooked on the tab 63 of the lid 6 and pushed up to open the lid body 62 as shown in FIG. 6. Next, the label lid 45 is peeled off from the upper surface of the sheet 42, leaving only a portion of it, to expose the cutout portion 44. Next, the fingers are inserted into the container 4 through the cutout portion 44 to pull out the wet sheet WS. After removing the wet sheet WS, the label lid 45 is adhered to the sheet 42 to close the cutout portion 44, and then the lid body 62 is pushed down to close the lid 6. (Method of manufacturing wet sheet package)

[0027] Next, a method for manufacturing the above-mentioned wet sheet package 1 will be described. As shown in Fig. 7, the manufacturing method for this wet sheet package includes a containerized wet sheet manufacturing step ST1 for manufacturing containerized wet sheets 2, a box body storing step ST2 for storing the containerized wet sheets 2 in a box body 5, and a lid bonding step ST3 for bonding a lid 6 to the box body 5.

[0028] The containerized wet sheet manufacturing process ST1 includes a wet sheet manufacturing process ST11 for manufacturing a wet sheet WS, a container storage process ST12 for storing the manufactured wet sheet WS in the container 4 from an upper opening 41, and a heat sealing process ST13 for covering and sealing the opening 41 of the container 4 with a sheet 42.

[0029] In the container-accommodating step ST12, as shown in FIG. 8, a container-accommodated wet sheet 2a having an unclosed opening is completed, which is composed of a container 4 having an unclosed opening 41 and a wet sheet WS accommodated therein.

[0030] In the heat sealing step ST13, the containerized wet sheet 2 is completed as shown in FIG. 2. The container 4 and the sheet 42 are each made of a thermoplastic, and the sheet 42 is provided with a cutout portion 44 and a label lid 45 in advance. To cover and seal the opening 41 of the container 4 with the sheet 42, the sheet 42 is heat-pressed to the flange 43 of the container 4 using a known heat pressing device as shown in FIG. 31 of Patent Document 1, for example. At that time, the flange 43 of the container 4 and the sheet 42 are heated, and the air sealed in the containerized wet sheet 2 is also heated and expanded by the residual heat. Therefore, in the containerized wet sheet 2 immediately after production, the sheet 42 is raised like the sheet 42 of the containerized wet sheet 2 in FIG. 9. Therefore, this heat sealing step not only covers and seals the opening 41 of the containerized wet sheet 2a whose opening is not closed with the sheet 42, but also serves as a heating step for heating the air sealed in the containerized wet sheet 2.

[0031] In the step ST2 of storing in a box body shown in Fig. 7, a containerized wet sheet 2b stored in a box body shown in Fig. 9 is completed. The containerized wet sheet 2b stored in a main box consists of a box body 5 of a packaging box 3 and a containerized wet sheet 2 immediately after completion in the heat sealing step ST13 stored therein. When the containerized wet sheet 2 is stored in the box body 5, the box body 5 is formed in advance as shown in Fig. 5. Also, the sheet 42 thermocompressed to the flange 43 of the containerized wet sheet 2 immediately after completion in the heat sealing step ST13 is raised as described above. Then, the containerized wet sheet 2 is stored in the box body 5 by pushing the containerized wet sheet 2 into the box body 5. When the containerized wet sheet 2 is pushed into the box body 5, the box body 5 is made of paperboard, so that the upper surface portion 50a etc. of the box body 5 are pushed up and bent by the raised sheet 42 of the containerized wet sheet 2, and the raised sheet 42 of the containerized wet sheet 2 is also pushed down by the upper surface portion 50a of the box body 5. Therefore, even if the sheet 42 is raised due to the thermal expansion of the air, as shown in Figure 9, the containerized wet sheet 2 can be stored.

[0032] The containerized wet sheet 2b stored in the box body shown in Fig. 7 is immediately transferred to the lid bonding process ST3 after completion. In the lid bonding process ST3, the lid 6 is attached to the box body 5 in a state where the thermal expansion of the air sealed in the containerized wet sheet 2 of the containerized wet sheet 2b stored in the box body is continued.

[0033] To attach the lid 6 to the box body 5, as shown in Figs. 10 and 11, adhesive G1 is applied in advance to the underside of the overhanging portion 65 of the window frame portion 61 of the lid 6 so as to cover the entire circumference of the outlet 64. At the same time, adhesive G2 is applied to the underside of the window frame portion 61 facing the upper surface of the box body 5. The adhesives G1 and G2 have the same components and properties, and are hot melt adhesives in this embodiment. In Fig. 10, the two-dot chain line indicates the position of the opening 51 of the box body 5, and the part of the window frame portion 61 surrounded by the two-dot chain line is the overhanging portion 65. The lid 6 with adhesive G1 and adhesive G2 applied to the window frame portion 61 becomes an adhesive-applied lid 6a. To attach the lid 6 to the box body 5, the adhesive-applied lid 6a is pressed against the container-containing wet sheet 2b already contained in the box body, with the orientation and position of both aligned. Then, the adhesive G1 applied to the underside of the overhanging portion 65 bonds the underside of the overhanging portion 65 of the window frame portion 61 to the upper surface of the sheet 42 of the containerized wet sheet 2. Also, the adhesive G2 bonds the underside of the window frame portion 61 to the upper surface of the box body 5. Then, thereafter, the air inside the containerized wet sheet 2 cools and contracts, and the wet sheet package 1 shown in FIG. 3 is completed. Second Embodiment

[0034] 12 is a perspective view of a wet sheet package according to a second embodiment of the present invention, and the wet sheet package 1 differs from the wet sheet package 1 according to the first embodiment of the present invention in that it has a sealing seal 7 affixed so as to straddle the upper surface of the lid 62 and the side surface of the box body 5. The sealing seal 7 has two dashed-line slits 71, 72 formed horizontally near the corner between the upper surface and the side surface of the lid 62, and near the corner between the side surface and the upper surface of the box body 5, respectively.

[0035] When the portion of the sealing seal 7 from the vertical end on the lid 6 side to the slit 71 is defined as the lid side attachment portion 7a, the portion of the sealing seal 7 from the vertical end on the box body 5 side to the slit 72 is defined as the box body side attachment portion 7b, and the portion of the sealing seal 7 between the slits 71 and 72 is defined as the break-and-remove portion 7c, the lid side attachment portion 7a and the box body side attachment portion 7b each have an adhesive or glue applied to them in advance, and neither adhesive nor glue is applied to the break-and-remove portion 7c.

[0036] To seal the wet sheet package 1 with this sealing seal 7, the lid side attachment portion 7a of the sealing seal 7 is attached to the top surface of the lid body 62 and the box body side attachment portion 7b is attached to the side of the box body 5.

[0037] When the wet sheet package 1 is sealed, the lid 6 of the wet sheet package 1 has a certain thickness, and the side of the lid 6 covered by the break-and-removed portion 7c of the sealing seal 7 is shifted a certain distance rearward from the side of the box body 5 to which the box body side attachment portion 7b is affixed, so that a space E is formed behind the break-and-removed portion 7c of the sealing seal 7.

[0038] To open the wet sheet package 1, insert a fingertip into the space E, grasp the breakable and removed portion 7c of the sealing seal 7, and tear it off along the cuts 71 and 72. Then, the lid-side affixed portion 7a and the box-body-side affixed portion 7b of the sealing seal 7 remain in a state of being stuck or adhered to the top surface of the lid 62 and the side surface of the box body 5.

[0039] By sealing with this sealing seal 7, it is no longer necessary to peel off the adhesive or glued portion of the sealing seal from the box body when opening, as in the past, so that opening can be done very easily and in a short time. Also, since the sealing seal 7 is broken linearly along the two cuts 71, 72, the lid side affixed portion 7a of the sealing seal 7 remaining on the lid 6 and the box body side affixed portion 7b of the sealing seal 7 remaining on the box body 5 are relatively neat and unlikely to give an uncomfortable feeling, and it is possible to prevent the sealing from damaging the aesthetic appearance of the wet wipes package 1.

[0040] The broken-line slits 71, 72 of the sealing seal 7 may be formed along a corner between the top and side surfaces of the lid 62 or directly above a corner between the side and top surfaces of the box body 5. Also, a tab extending laterally may be formed in the breakable removal portion 7c, and the breakable removal portion 7c may be torn off by pinching this tab with fingers. [Explanation of symbols]
