Description

The present invention relates to a wet sheet package that can packaged removed wet sheet such as wet tissue, cosmetic face mask.

  For wet sheet packaging, which is a stack of wet sheets such as a wet tissue and a face mask for cosmetics, and packaged so that it can be taken out in an outer bag, use an outer bag with gas barrier properties and take it out on the upper surface of the outer bag. A mouth and an adhesive sealing sheet that seals the take-out port are provided. If necessary, the seal sheet is peeled off, and the wet sheet is taken out from the take-out port. Some are sealed.

  Since this type of wet sheet package is required to have a gas barrier property, after the wet sheet is taken out, it is necessary to seal the sealing sheet by sticking it to the entire outer periphery of the take-out port. However, since the outer bag uses a single film or a composite film of a thin plastic film having gas barrier properties, the outer bag itself does not have sufficient shape retention and the remaining amount of the internal wet sheet is reduced. When sticking the sealing sheet, wrinkles and the like are likely to occur in the peripheral portion of the outer bag take-out port. Therefore, it is necessary to stick the sealing sheet while extending the crease formed around the outlet.

  Therefore, in the conventional wet sheet package, a shape retaining frame is provided on the outer peripheral portion of the sealing sheet adhering region on the upper surface side of the outer bag, and the outer peripheral portion of the outer bag take-out port is reinforced by this shape retaining frame. What is made (Patent Document 1), or a sheet in which a reinforcing sheet is attached to the peripheral portion of the take-out port on the upper surface side of the outer bag, and a sealing sheet is attached to the reinforcing sheet (Patent Document 2). Proposed.

  Each surface of the outer bag 6 is substantially square, and as shown in FIG. 1, an outer take-out port 18 and a sealing sheet 19 for opening and closing the outer take-out port 18 are provided on the upper surface portion 17. Yes. The outer take-out port 18 is formed in a substantially rectangular shape having a size suitable for taking out the face mask 2. The sealing sheet 19 includes an adhesive portion 20 formed on the entire outer periphery of the outer take-out port 18, a knob portion 21 provided on the outer side of the adhesive portion 20, and a release provided on the opposite side of the knob portion 21. The other adhesive part 20 except the adhesive part 20 between the peeling prevention parts 22 is stuck to the upper surface part 17 so that peeling is possible. Note that a cut piece 23 corresponding to the outer take-out port 18 of the outer bag 6 is affixed to the sealing sheet 19.

  The inner container 5 is a thin plastic molded product having a shape-retaining property. As shown in FIGS. 2 and 3, the container body 25, and the opening 26 side of the container body 25 are provided with engagement means 27. An inner lid 28 that is detachably attached and a tray 30 that is disposed below the container main body 25 via positioning means 29 are provided.

  The container body 25 has a taper shape extending upward, and a plurality of reinforcing portions 32 that are long in the vertical direction are provided on the peripheral wall portion 31, and an engagement flange portion 33 that is bent outward is further provided on the outer periphery of the upper end on the opening 26 side. Protrusions 35 that receive the laminate 3 are respectively provided on the bottom wall 34. The reinforcing portion 32 is for ensuring the rigidity in the vertical direction of the peripheral wall portion 31 and is recessed inwardly in a groove shape, but may be provided so as to protrude outwardly. The projecting portion 35 has a planar viewing angle shape continuous in the circumferential direction, and a plurality of concentric strips are provided. The protruding portion 35 protrudes upward from the bottom wall portion 34 of the container main body 25, and the back side is a positioning recess 36.

  The inner lid 28 and the tray 30 have substantially the same size on the outer diameter side, and are configured such that the upper and lower sides of the wet sheet packaging body 1 have substantially the same size when wrapped by the outer bag 6. The inner lid 28 has a peripheral wall portion 37 that is detachably fitted on the outer peripheral side of the engagement flange portion 33 of the container body 25, and a ceiling-side receiving portion 38 that is integrally formed on the upper side of the peripheral wall portion 37. The inner side of the receiving portion 38 is an inner outlet 39.

  The inner outlet 39 corresponds vertically to the outer outlet 18 of the outer bag 6 and is slightly larger than the outer outlet 18. The receiving portion 38 corresponds to the adhesive portion 20 of the sealing sheet 19 and is configured to receive the upper surface portion 17 of the outer bag 6 from the lower side at the outer periphery of the outer take-out port 18 when the sealing sheet 19 is stuck. Yes. The tray 30 has a bottom wall portion 40 and a peripheral wall portion 41.

  The engagement means 27 includes an engagement flange portion 33 of the container body 25 and an engagement portion 42 provided on the inner periphery of the peripheral wall portion 37 of the inner lid 28 and detachably engaged with the engagement flange portion 33. ing. The engaging portion 42 is formed to protrude inward from the peripheral wall portion 37. The positioning means 29 includes a positioning recess 36 on the bottom wall 34 side of the container body 25 and a positioning protrusion 43 formed to protrude from the bottom wall 40 of the tray 30, and the positioning protrusion 43 is formed on the container body 25. Both are positioned laterally by entering the positioning recess 36 from below.

  The wet sheet packaging body 1 having such a configuration has the following advantages. When the face mask 2 is used, the sealing sheet 19 is pulled in the peeling direction with the knob 21. Then, the sealing sheet 19 is peeled and the outer take-out port 18 is opened, and the uppermost face mask 2 of the laminate 3 can be taken out through the outer take-out port 18 and the inner take-out port 39 of the inner lid 28.

  After taking out the face mask 2, the sealing sheet 19 is attached to the upper surface portion 17 of the outer bag 6 through the adhesive portion 20. In this case, the laminated body 3 of the face mask 2 is contained in the container main body 25 of the inner container 5 in the outer bag 6, and the outer outlet 18 of the outer bag 6 is covered by the inner lid 28 mounted on the upper side of the container main body 25. Therefore, there is an advantage that the sealing sheet 19 can be easily and reliably attached.

  Further, the inner container 5 has a receiving tray 30 corresponding to the inner lid 28 on the lower side of the container main body 25. Since the inner container 5 is packaged in the outer bag 6, the container main body 25 is tapered. In addition, the wet sheet package 1 can be finished with good appearance.

  Therefore, in this wet sheet packaging body 1, the form of the exterior bag 6 is greatly changed regardless of the remaining amount of the internal face mask 2 compared to the case where a reinforcing sheet or the like is provided outside the conventional exterior bag 6. Thus, the appearance can be improved, and there is an advantage that the outside take-out port 18 can be easily opened and closed by operating the sealing sheet 19.

  Moreover, since the inner lid 28 is attached to the container main body 25 via the engaging means 27 and the tray 30 is attached to the container main body 25 via the positioning means 29, the outer bag 6 holds the inner container 5 in place. The correspondence between the inner lid 28 and the tray 30 can be kept constant before and after the packaging, and the outer bag 6 can be prevented from being deformed after opening.

  When the wet sheet package 1 is manufactured, it may be manufactured automatically or semi-automatically using a manufacturing line, or may be manufactured manually. For example, when using a production line, as shown in FIGS. 5 to 7, while the container body 25 or the inner container 5 is intermittently conveyed in the arrow direction by the first conveyor 45, the second conveyor 46, etc., First cosmetic liquid injection process 50, first face mask charging impregnation process 51, second cosmetic liquid injection process 52, second face mask charging impregnation process 53, drop film charging process 54, lid mounting process 55, saucer mounting The wet sheet package 1 is manufactured automatically or semi-automatically through the step 56, the inner container inserting step 57, the gusset bag sealing step 59, the adhesive coating step 60, the end folding step 61 and the like.

  The injection of the cosmetic liquid 4 into the container body 25 and the insertion of the laminated body 3 of the face mask 2 are performed in half approximately twice as shown in FIGS. First, in the first cosmetic liquid injection step 50, substantially half of the cosmetic liquid 4 is injected from the injection nozzle 62 into the container body 25 on the first conveyor 45. In the next first face mask charging and impregnation step 51, the lower laminated portion 3a of the lower half of the laminated body 3 in which the folded face mask 2 is laminated is held by the holding means 63, and the top of the cosmetic liquid 4 The container body 25 is charged.

  When the laminated body 3 enters the container body 25, the holding means 63 releases the holding of the laminated body 3, and the holding means 63 or the compressing means 64 that is integral with or separate from the holding means 63 is placed under the laminated body 3 in the container body 25. The substantially entire layered portion 3a is compressed downward into the cosmetic liquid 4, and then the compression is released. If it does in this way, when the laminated body 3 decompress | restores from a compression state, the cosmetic liquid 4 in the container main body 25 can be efficiently absorbed in each face mask 2 of the laminated body 3 in a short time.

  Similarly, in the second cosmetic liquid injection step 52, the remaining half of the cosmetic liquid 4 is injected by the injection nozzle 65, and in the second face mask charging and impregnation step 53, the upper half of the laminate 3 in the remaining half of the laminated body 3b. Is inserted into the container body 25 by the holding means 66 and stacked on the lower laminated portion 3a, and the whole laminated body 3 including the upper and lower laminated portions 3a and 3b is compressed by the compressing means 67, The cosmetic liquid 4 is absorbed by the entire laminate 3 by releasing the compression.

  It is desirable to put the cosmetic liquid 4 in the container body 25 to such an extent that the entire laminate 3 is immersed. Further, since the folded face mask 2 is thick at the folded portion, the rear upper laminated portion 3b is loaded so as to be opposite to the previously loaded lower laminated portion 3a. Thereby, the stability of the laminated body 3 in the container body 25 is improved, and the cosmetic liquid 4 can be evenly absorbed by the laminated body 3.

  Note that vacuum holding means or the like can be adopted as the holding means 63 and 66. In that case, if the laminated body 3 is adsorbed in a compressed state by the holding means 63 and 66 and loaded into the container body 25, the laminated body 3 can be released by releasing the compressed state of the laminated body 3 in the container body 25. The cosmetic liquid 4 can be absorbed.

  In the drop film charging step 54, as shown in FIGS. 5 and 6, a rectangular drop film 68 that is larger than the opening amount of the inner outlet port 39 of the inner lid 28 on the laminated body 3 in the container body 25. Is charged. The dropping film 68 adheres to the upper surface of the laminate 3 with the cosmetic liquid 4 in the container body 25 attached thereto. Therefore, even if the wet sheet packaging 1 after packaging is turned upside down, the falling film 68 will block the inner take-out port 39 of the inner lid 28, and the laminated state of the laminated body 3 in the inner container 5 is disturbed. Can be prevented.

  In the lid mounting step 55, as shown in FIGS. 5 and 6, the inner lid 28 is mounted on the opening 26 side of the container body 25 using the lifting / moving suction means 69. In this case, after the inner lid 28 is adsorbed by the adsorbing means 69, the adsorbing means 69 is lowered to align the inner lid 28 with the opening 26 of the container main body 25, and the inner lid 28 is attached to the container main body 25 via the engaging means 27. Install on top. As a result, the inner lid 28 after being mounted does not come off from the opening 26 side of the container body 25, and the subsequent work and other handling can be performed easily and smoothly.

  For example, even when the tray 30 is mounted on the lower side of the container body 25 in the next tray mounting step 56, the inner lid 28 is engaged with the container body 25 via the engagement means 27, so the suction means 69. As a result, the container body 25 and the inner lid 28 can be lifted together.

  Therefore, in the tray mounting step 56, as shown in FIGS. 5 to 7, after the container body 25 is moved above the tray 30 on the receiving base 70, the suction means 69 is lowered to receive the container body 25. 30. And after the container main body 25 gets on the saucer 30, it presses below with the adsorption | suction means 69, and the positioning convex part 43 and the positioning recessed part 36 of the positioning means 29 are couple | bonded.

  Thereby, the container main body 25 can be positioned on the receiving tray 30 via the positioning means 29, and the inner lids 28 and the receiving trays 30 on both upper and lower sides of the container main body 25 can be substantially aligned vertically. Therefore, although the container body 25 of the inner container 5 is tapered, the finished state of the wet sheet package 1 after being packaged in the outer bag 6 can be improved.

  In the inner container insertion step 57, as shown in FIGS. 5 and 6, the cosmetic liquid 4 and the laminate 3 are placed in the container body 25, and the inner lid 28 and the tray 30 are mounted on both upper and lower sides of the container body 25. The inner container 5 in a state is inserted into the gusset bag 15. A gusset bag 15 is used in which one end side is open 13 and the other end side is closed. As shown in FIGS. 9 and 10, the gusset bag 15 is placed sideways on the guide plate 71 so that the outer take-out port 18 and the sealing sheet 19 are on the upper side, and the opening 13 side is the receiving table 70 side. It is mounted in a state where it is expanded by the holding guide piece 73 of the holding frame 72 mounted on the frame.

  Next, the inner container 5 is pressed toward the gusset bag 15 by the pressing means 74 and pushed into the gusset bag 15 from the opening 13 side as shown in FIG. 7, and the inner container 5 is closed on the other end side of the gusset bag 15. Move to the side. When the inner container 5 is pressed by the pressing means 74 even after the inner container 5 has moved to the other end side of the gusset bag 15, the gusset bag 15 is detached from the holding frame 72 and remains inside the gusset bag 15. Can be transferred onto the second conveyor 46.

  The second conveyor 46 is intermittently moved in the direction of the arrow, and as shown in FIGS. 5 and 7, the inner container 5 contained in the gusset bag 15 is moved from the transfer position to the gusset bag sealing step 59, adhesive. It conveys to the coating process 60 and the edge part folding process 61. FIG.

  In the gusset bag sealing step 59, the opening 13 side of the gusset bag 15 is folded back and forth and up and down near the inner container 5, and then closed by heat welding with the heat welding means 75. As a result, the inner container 5 containing the laminate 3 and the cosmetic liquid 4 can be packaged in a sealed manner.

  In the adhesive coating process 60, the adhesive 78 is applied to both side surfaces of the gusset bag 15 by a coating means 76 such as a coating nozzle. In the end folding step 61, the end 79 protruding from the gusset bag 15 is folded downward along the left and right side surfaces by the folding means 80 and bonded by the adhesive 78. Thereby, the manufacture of the wet sheet package 1 is completed, and the wet sheet package 1 can be finished in a state close to a substantially rectangular parallelepiped.

  When the belt-like sealing sheet is wound around the outer periphery of the wet sheet packaging body 1 in the opening direction of the sealing sheet 19 or in a direction perpendicular to the opening direction, and the sealing sheet 19 is peeled off and the wet sheet 2 is taken out, The sealing sheet may be removed and opened.

  As mentioned above, although embodiment of this invention was explained in full detail, this invention is not limited to this embodiment, A various change is possible. For example, the cosmetic liquid 4 and the laminate 3 are put in the container body 25 in two steps, but may be once or three or more depending on the amount.

  In addition, the receiving tray 30 is mounted on the lower side of the container body 25 after the cosmetic liquid 4 and the laminate 3 are put in the container body 25 and the inner lid 28 is mounted, but before the inner lid 28 is mounted. It may be attached to the container body 25. For example, the cosmetic liquid 4 and the laminate 3 may be put in a state where the container body 25 is placed on the receiving tray 30.

  The container body 25 of the inner container 5 may be flat. For example, in the case of the face mask 2, the wet sheet 2 is first folded in a double fold shape, and then further folded in a tri-fold shape. It may be folded in two or three. In the case where the number of laminated sheets of such wet sheets 2 is small, the container body 25 may be configured to be flat.

  In the embodiment, the case of manufacturing automatically or semi-automatically while moving along the manufacturing line is illustrated, but this manufacturing line is merely an example, and a manufacturing line of another configuration may be adopted, A part or all of them may be performed manually.

  When the inner lid 28 and the tray 30 are manufactured, a molded product having the same shape as the tray 30 is formed, the molded product is used as it is as the tray 30, and a part corresponding to the inner outlet 39 of the molded product is excised. It may be used as the inner lid 28. In this case, since one type of molded product can be used for both the inner lid 28 and the tray 30, the manufacturing cost can be reduced. However, the inner lid 28 and the tray 30 may be separately molded from the beginning.

  The wet sheet 2 may be previously wetted outside the container body 25 in a stacked state, and then inserted into the container body 25. When packaging the inner container 5 with the outer bag 6, in the embodiment, the gusset bag 15 having an opening 13 on one end side is used, and the inner container 5 is inserted into the gusset bag 15 from the opening 13 side. The bag 15 does not need to be provided, and the inner container 5 may be wrapped and sealed in a sealed manner while feeding the sheet-shaped exterior material in the longitudinal direction.
