Description

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

  Wet gas sheets, such as wet tissues and face masks for makeup, are stacked and packaged in an outer bag so that they can be taken out. A mouth and an adhesive-type sealing sheet for sealing the outlet are provided in advance, and if necessary, the sealing sheet is peeled off and the wet sheet is taken out from the outlet, and then the sealing sheet is attached and the outlet is opened. Some are designed to be sealed.

  Since this type of wet sheet package is required to have gas barrier properties, after the wet sheet is taken out, it is necessary to attach the sealing sheet to the entire outer circumference of the taking-out port to seal it. However, since the outer bag uses a single film or a composite film of a thin plastic film having a gas barrier property, the outer bag itself does not have sufficient shape-retaining property and if the remaining amount of the wet sheet inside is small. When the sealing sheet is attached, wrinkles or the like are likely to occur in the peripheral portion of the outlet of the outer bag. Therefore, it is necessary to attach the sealing sheet while stretching out wrinkles and the like formed around the take-out port.

  Therefore, a conventional wet sheet package is provided with a shape-retaining frame on the outer peripheral portion of the attachment area of the sealing sheet on the upper surface side of the outer bag, and the shape-retaining frame reinforces the peripheral portion of the outlet of the outer bag. (Patent Document 1), or a reinforcing sheet attached to the peripheral portion of the outlet on the upper surface side of the outer bag, and a sealing sheet attached to this reinforcing sheet (Patent Document 2). Proposed.

  Conventionally, a shape-retaining frame and a reinforcing sheet are attached to the upper surface of the outer bag, so not only does the appearance look bad and it is difficult to give a high-class appearance, but also the outer surface of the outer bag may be affected by the remaining amount of the wet sheet. If the height of the upper surface side of the bag changes greatly and the remaining amount of the wet sheet becomes small, there is a problem that opening and closing of the take-out port by peeling and sticking the sealing sheet becomes complicated.

  In the case of an outer bag that uses a shape-retaining frame, a shape-retaining frame is provided on the outer peripheral portion of the sticking area for sticking the sealing sheet to the outer bag to surround the sticking area, Since the upper side of the bag body is shaped by the shape-keeping frame on the outer peripheral side and the sealing sheet is attached to the inside sticking area, wrinkles or the like may occur at the place where the sealing sheet is attached. There is

  Furthermore, in the case of an outer bag that uses a reinforcing sheet, since only one reinforcing sheet is fixed to the peripheral portion of the outlet of the bag body, if the remaining amount of the wet sheet decreases, the reinforcing sheet itself There is a risk that it will be deformed, and there is a problem that it cannot be reliably sealed.

The present invention aims to such consideration of the conventional problems, to provide a wet sheet package that can hold the outer bag regardless somewhat of remaining inside the wet sheet into a substantially rectangular shape or a substantially cubic shape And

The present invention is a wet sheet package in which a laminate of wet sheets is housed in an outer bag, and the wet sheet can be taken out from an outer outlet on the upper surface side of the outer bag, in the outer bag, comprising a container for housing the laminated body, and a holding member for holding the intervening are and shape of the outer bag between the container and the outer bag from the inside a substantially rectangular parallelepiped shape or a substantially cubic shape, the container has an upper A tapered peripheral wall portion, a bottom wall portion integrally formed by bending inward from a lower end of the peripheral wall portion, and an outer peripheral edge integrally formed by being bent outward from an upper end of the peripheral wall portion. The holding member includes a lower holding part disposed separately from the container on the lower side of the container, and a positioning means for positioning the lower holding part with respect to the container. .

According to the present invention, there is some advantages that can hold the outer bag in a substantially rectangular shape or a substantially cubic shape irrespective of the remaining amount of internal wet sheet.

The face mask 2 is an example of a wet sheet, and a wet tissue or the like can be used in the same manner. Further, in the case of the face mask 2, the cosmetic liquid 4 is used as the wetting liquid, but when the wet sheet is a wet tissue or the like, instead of the cosmetic liquid 4, a moisturizing liquid according to each application is used. A liquid may be used.

  The laminated body 3 is folded in two at a substantially center folding line 10 shown in FIG. 4 (A), and is then folded at three folding lines 11 in a direction substantially orthogonal to the folding line 10 in a three-fold form, and then the stack 3 is formed as shown in FIG. 4), the face mask 2 in a folded state after being formed into a size suitable for being accommodated in the inner container 5 is formed by vertically stacking a plurality of sheets as shown in FIG. 4C. When the number of the face masks 2 to be laminated is large, it is desirable that the laminated body 3 is divided into a lower laminated portion 3a of the lower half and an upper laminated portion 3b of the upper half and inserted in opposite directions.

  The outer bag 6 is made in a gusset type using an outer material such as a composite film or a composite sheet having a gas barrier property, and the side surface portions 12 of the outer bag 6 are arranged along the left and right sides of the inner container 5 in the front and rear direction. After being folded in a mountain fold shape from both sides, it is folded in a mountain fold shape from both upper and lower sides and fixed in a substantially flat shape along seal lines near both left and right sides of the inner container 5.

  When manufacturing the wet sheet package 1, as shown in FIGS. 7 and 10, one end side in the left-right direction has an opening 13 and the other end side is sealed with a sealing portion 14, and a gusset bag 15 is used. After inserting the inner container 5 into the gusset bag 15 and moving it to the other end side, the opening 13 on one end side of the gusset bag 15 is sealed.

  Each surface of the outer bag 6 has a substantially square shape, and as shown in FIG. 1, the upper surface portion 17 thereof is provided with an outer outlet port 18 and a sealing sheet 19 for sealing the outer outlet port 18 openably and closably. There is. 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 peripheral side of the external outlet 18, a grip portion 21 provided outside the adhesive portion 20, and a peeling portion provided on the opposite side of the grip portion 21. An adhesive portion 20 having a blocking portion 22 and excluding the adhesive portion 20 between the peeling blocking portions 22 is peelably attached to the upper surface portion 17. A cut piece 23 corresponding to the external outlet 18 of the outer bag 6 is attached 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 inner container 5 is provided with a container body 25 and an engaging means 27 on the opening 26 side of the container body 25. It is provided with an inner lid 28 which is detachably attached, and a tray 30 which is arranged below the container body 25 via positioning means 29.

  The container body 25 has a tapered shape that spreads upward, and a plurality of vertically long reinforcing portions 32 are provided on the peripheral wall portion 31, and an engaging flange portion 33 that bends outward is provided on the outer periphery of the upper end on the opening 26 side. The bottom wall portion 34 is provided with protrusions 35 for receiving the laminated body 3, respectively. The reinforcing portion 32 is for ensuring the rigidity of the peripheral wall portion 31 in the vertical direction, and is recessed inward in the shape of a groove, but may be provided so as to protrude outwardly. The projection 35 has a plan view angle shape continuous in the circumferential direction, and is provided with a plurality of concentric lines. The projection 35 projects upward from the bottom wall 34 of the container body 25, and the back side thereof serves as 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 so that the upper and lower sides of the wet sheet package 1 have substantially the same size when packaged 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 engaging collar 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 inside of the receiving portion 38 serves as an internal outlet 39.

  The inner outlet 39 corresponds to the upper and lower sides of 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 ejection port 18 when the sealing sheet 19 is attached. There is. 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 that is provided on the inner periphery of the peripheral wall portion 37 of the inner lid 28 and that engages with the engagement flange portion 33 in a disengageable manner. ing. The engagement portion 42 is formed so as 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 so as to project from the bottom wall 40 of the tray 30, and the positioning protrusion 43 of the container body 25 is provided. The two are positioned laterally by entering the positioning recess 36 from below.

  The wet sheet package 1 having such a structure has the following advantages. When the face mask 2 is used, the grip sheet 21 is held and the sealing sheet 19 is pulled in the peeling direction. Then, the sealing sheet 19 is peeled off to open the outer take-out port 18, 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 via the adhesive portion 20. In this case, the laminated body 3 of the face mask 2 is contained in the container body 25 of the inner container 5 in the outer bag 6, and the inner lid 28 mounted on the upper side of the container body 25 removes the outer bag 18 from the outer bag 18. Since the outer peripheral portion of the sealing sheet is received, there is an advantage that the sealing sheet 19 can be easily and surely attached.

  Further, the inner container 5 has a tray 30 corresponding to the inner lid 28 on the lower side of the container body 25. Since the inner container 5 is put in the outer bag 6 for packaging, the container body 25 has a tapered shape or the like. Also, the wet sheet package 1 can be finished in a good appearance.

  Therefore, in this wet sheet package 1, the form of the outer bag 6 is greatly changed as compared with the case where a reinforcing sheet or the like is provided outside the conventional outer bag 6, regardless of the remaining amount of the face mask 2 inside. There is an advantage that the appearance can be made good without doing so, and the outer ejection port 18 can be easily opened and closed by operating the sealing sheet 19.

  Moreover, the inner lid 28 is attached to the container body 25 via the engaging means 27, and the tray 30 is attached to the container body 25 via the positioning means 29. Before and after packaging, the correspondence between the inner lid 28 and the tray 30 can be kept constant, and the outer bag 6 can be prevented from losing its shape after opening.

  When manufacturing the wet sheet package 1, it may be manufactured automatically or semi-automatically using a manufacturing line, or may be manufactured manually. For example, when using a manufacturing line, as shown in FIGS. 5 to 7, while intermittently conveying the container body 25 or the inner container 5 in the arrow direction by the first conveyor 45, the second conveyor 46, and the like, First cosmetic liquid injection step 50, first face mask charging impregnation step 51, second cosmetic liquid injection step 52, second face mask charging impregnation step 53, drop film charging step 54, lid mounting step 55, saucer mounting The wet sheet package 1 is automatically or semi-automatically manufactured 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 charging of the laminated body 3 of the face mask 2 are carried out in two substantially half steps as shown in FIGS. First, in the first cosmetic liquid injection step 50, approximately 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 impregnation step 51, the lower half 3a of the lower half of the laminated body 3 in which the face masks 2 in the folded state are laminated is held by the holding means 63, and the upper surface of the cosmetic liquid 4 is held. It is loaded into the container body 25 from the inside.

  When the laminated body 3 enters the container body 25, the holding means 63 releases the holding of the laminated body 3 and then the compression means 64 integrated with the holding means 63 or a separate body lowers the laminated body 3 inside the container body 25. Almost the entire laminated portion 3a is compressed downward into the cosmetic liquid 4, and thereafter the compression is released. By doing so, when the laminated body 3 is restored from the compressed state, the cosmetic liquid 4 in the container body 25 can be efficiently absorbed by each face mask 2 of the laminated body 3 in a short time.

  Similarly, in the second cosmetic liquid injecting step 52, the other half of the cosmetic liquid 4 is injected by the injection nozzle 65, and in the second face mask charging / impregnating step 53, the upper half portion 3b of the other half of the laminate 3 is similarly injected. Is loaded into the container main body 25 by the holding means 66 and stacked on the lower laminated portion 3a, and the entire laminated body 3 including the upper and lower laminated portions 3a and 3b is compressed by the compression means 67, By releasing the compression, the entire body of the laminate 3 absorbs the cosmetic liquid 4.

  It is desirable that the cosmetic liquid 4 in the container body 25 be added to such an extent that the entire laminated body 3 is immersed. Further, since the folded face mask 2 has a thicker folded portion, the rear upper laminated portion 3b is inserted in the opposite direction to the lower laminated portion 3a inserted first. This improves the stability of the laminate 3 in the container body 25, and allows the laminate 3 to absorb the cosmetic liquid 4 evenly.

  It is also possible to adopt vacuum suction means or the like for the holding means 63, 66. In this case, the laminated body 3 is adsorbed in a compressed state by the holding means 63 and 66, loaded into the container body 25, and then the compressed state of the laminated body 3 is released in the container body 25. It is also possible to absorb the cosmetic liquid 4.

  In the dropping film charging step 54, as shown in FIGS. 5 and 6, a rectangular dropping film 68 larger than the opening amount of the inner take-out port 39 of the inner lid 28 is provided on the laminated body 3 in the container body 25. Charge. The cosmetic film 4 in the container body 25 adheres to the drop film 68 and adheres to the upper surface of the laminated body 3. Therefore, even if the wet sheet package 1 after packaging is turned upside down, the dropping film 68 closes 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 body 25, and the inner lid 28 is inserted through the engaging means 27. Mount on top. As a result, the inner lid 28 after mounting 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, when the tray 30 is attached to the lower side of the container body 25 in the next tray attachment step 56, since the inner lid 28 is engaged with the container body 25 via the engagement means 27, the suction means 69. Can be raised to integrally lift the container body 25 and the inner lid 28.

  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 pedestal 70, the suction means 69 is lowered to receive the container body 25. Place on top of 30. Then, after the container body 25 is placed on the tray 30, it is pressed downward by the suction means 69 to connect the positioning convex portion 43 and the positioning concave portion 36 of the positioning means 29.

  Thus, the container body 25 can be positioned on the tray 30 via the positioning means 29, and the inner lids 28 on the upper and lower sides of the container body 25 and the tray 30 can be substantially aligned vertically. Therefore, even though 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 inserting step 57, as shown in FIGS. 5 and 6, the cosmetic liquid 4 and the laminated body 3 are put in the container body 25, and the inner lid 28 and the saucer 30 are attached to both upper and lower sides of the container body 25. The inner container 5 in the state is inserted into the gusset bag 15. As the gusset bag 15, one having an opening 13 at one end and a closed end at the other end is used. Then, as shown in FIGS. 9 and 10, the gusset bag 15 is laid sideways on the guide plate 71 so that the outer ejection port 18 and the sealing sheet 19 are on the upper side, and the opening 13 side is on the pedestal 70 side. The holding frame 72 is attached to the holding frame 72 so that the holding frame 72 is spread by the holding guide piece 73.

  Then, the pressing means 74 presses the inner container 5 toward the gusset bag 15 and pushes it into the gusset bag 15 from the opening 13 side as shown in FIG. 7 to close the inner container 5 on the other end side of the gusset bag 15. Close 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 disengaged from the holding frame 72 and remains inside the gusset bag 15 while remaining 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 and the adhesive. It is adapted to be conveyed to a coating process 60 and an end folding process 61.

  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 in the very vicinity of the inner container 5 and then closed by heat welding by the heat welding means 75. As a result, the inner container 5 containing the laminated body 3 and the cosmetic liquid 4 can be packaged in a hermetically sealed manner.

  In the adhesive application step 60, the adhesive 78 is applied to both side surfaces of the gusset bag 15 by the application means 76 such as an application nozzle. In the end portion folding step 61, the end portion 79 protruding from the gusset bag 15 is folded downward along the left and right side surfaces by the folding means 80 and adhered by the adhesive 78. As a result, the production of the wet sheet package 1 is completed, and the wet sheet package 1 can be finished in a substantially rectangular parallelepiped state.

  A strip-shaped sealing sheet is wound around the outer periphery of the wet sheet package 1 in the opening direction of the sealing sheet 19 or in a direction orthogonal to the opening direction, and when the sealing sheet 19 is peeled off and the wet sheet 2 is taken out, The sealing sheet may be removed and opened.

  Although the embodiment of the present invention has been described above in detail, the present invention is not limited to this embodiment and various modifications can be made. For example, although the cosmetic liquid 4 and the laminated body 3 are put in the container body 25 in two divided portions, the amount may be one or three or more depending on the amounts.

  Further, the saucer 30 is mounted on the lower side of the container body 25 after the cosmetic liquid 4 and the laminated body 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 solution 4 and the laminated body 3 may be placed with the container body 25 placed on the saucer 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 two and then further folded in three, but in the case of a sheet long in one direction, the wet sheet 2 is cut in the longitudinal direction. It may be folded in two or three. When the number of laminated sheets of such wet sheets 2 is small, the container body 25 may be formed in a flat shape.

  In the embodiment, the case of automatically or semi-automatically manufacturing while moving along the manufacturing line is illustrated, but this manufacturing line is merely an example, and manufacturing lines of other configurations may be adopted, You may make it perform some or all by hand.

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

  The wet sheet 2 may be preliminarily moistened outside the container body 25 in a laminated state and then inserted into the container body 25. In packaging the inner container 5 with the outer bag 6, in the embodiment, a 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 have to be the bag 15, and the inner container 5 may be wrapped in a hermetically sealed manner by wrapping the sheet-shaped exterior material in the longitudinal direction and wrapping the inner container 5 with the exterior material.
