Description

[Technical Field]

[0001] This invention relates to an absorbent article packaging. [Background technology]

[0002] Traditionally, absorbent items such as disposable diapers have been sold commercially as absorbent item packages, with multiple items stacked together and housed in a packaging bag. These packaging bags typically have perforations, and opening the bag along the perforations creates an opening for removing the absorbent items.

[0003] For example, Patent Document 1 discloses a packaging bag for compressed articles (disposable diapers) with an opening, wherein the packaging bag for compressed articles is roughly rectangular in shape, and has a continuous perforation or cut that runs from the front panel through the top panel to the back panel, and in the top panel, avoids the opening for the handle formed in the handle portion and crosses the handle portion. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 7-187197 [Overview of the project] [Problems that the invention aims to solve]

[0005] However, in the packaging bag for absorbent article packaging described in Patent Document 1, diapers placed away from the opening, which is opened by tearing along the perforations, may remain inside the packaging bag even after the diapers near the opening have been removed. These remaining diapers may be difficult to remove because they are covered by the packaging bag. Furthermore, since the opening remains open at all times after the packaging bag is opened along the perforations, there is a possibility that dirt, dust, and other debris may enter through the opening.

[0006] In view of the above, one aspect of the present invention aims to provide an absorbent article packaging that allows absorbent articles to be easily removed from the opening and prevents waste from entering through the opening. [Means for solving the problem]

[0007] A first embodiment of the present invention is an absorbent article package in which an absorbent article laminate, of which a plurality of absorbent articles are stacked, is contained in a packaging bag, the package having a bottom portion, a front portion and a rear portion, a pair of side portions connected to the front portion and the rear portion, and a sealing portion to which the upper ends of the front portion and the rear portion are joined, wherein the plurality of absorbent articles are stacked in a stacking direction from one side portion to the other side portion, perforations are formed in the front portion along the stacking direction, on the bottom portion side of the sealing portion and above the upper end of the absorbent article laminate, the ends of the perforations are located outside a position 30 mm inward from the end of the absorbent article laminate in the stacking direction, and the distance between the ends of the perforations and the edge of the front portion in the stacking direction is 3% or more of the total length of the perforations.

[0008] According to the first embodiment described above, by opening the packaging bag vertically along the perforations, an opening is formed above the upper end of the absorbent article stack, exposing the upper end of the absorbent article stack in the stacking direction, and the upper end of the absorbent article contained in the packaging bag is exposed. Therefore, the absorbent article can be easily removed from the opening by grasping its upper end. Furthermore, after opening the packaging bag, the packaging bag covers everything except the upper end of the absorbent article stack, and the opening can be closed by overlapping the part of the packaging bag above the perforations with the outer surface of the front part located below the perforations, thereby preventing waste from entering through the opening.

[0009] A second embodiment of the present invention is that the distance between the perforation and the upper end of the packaging bag is 30% to 70% of the length of the absorbent article laminate in the direction along the side portion.

[0010] According to the second embodiment described above, after opening the packaging bag, the area of ​​the portion of the packaging bag located above the perforations can be made sufficiently large. Therefore, when this portion is superimposed on the outer surface of the front portion located below the perforations, the overlapping area can be increased. As a result, the dispensing opening can be kept closed for a longer period of time, and the entry of waste through the dispensing opening can be further suppressed.

[0011] A third embodiment of the present invention is that the distance between the perforation and the upper end of the absorbent article laminate is 20 mm to 80 mm.

[0012] According to the third embodiment described above, when removing the absorbent article after opening the packaging bag, interference from the front portion that protrudes above the absorbent article stack can be suppressed, and the absorbent article can be removed more easily from the opening.

[0013] A fourth embodiment of the present invention is that the length of the tie portion of the perforation is 1.0 mm to 15 mm, and the length of the cut portion of the perforation is 0.5 mm to 2.0 mm.

[0014] According to the fourth embodiment described above, even if the packaging bag has a paper base material and a sealing layer, it can be easily opened up to both ends of the perforations, so that an opening is formed that exposes the upper end of the stacked absorbent articles in the stacking direction, and the upper end of the absorbent articles contained in the packaging bag is exposed. Therefore, the absorbent articles can be easily removed from the opening by pinching the upper end of the absorbent articles.

[0015] In a fifth embodiment of the present invention, the distance between the end of the perforation and the edge of the front portion in the stacking direction is 15 mm or more.

[0016] According to the fifth form described above, when the absorbent article packaging is packed during the distribution process or when it is carried by the user, the risk of the packaging bag tearing from the perforated ends can be further suppressed, and when the absorbent article is used, the absorbent article can be easily removed from the opening.

[0017] In the sixth aspect of the present invention, in a state where the packaging bag is opened along the perforation, the front portion and the rear portion are upright with respect to the bottom portion.

[0018] According to the above sixth aspect, when taking out the absorbent article, it is possible to prevent the front portion and the rear portion protruding above the absorbent article from covering the upper end of the absorbent article, and the state where the upper end of the absorbent article housed in the packaging bag is exposed is maintained. Therefore, the absorbent article can be taken out more easily from the take-out opening.

[0019] In the seventh aspect of the present invention, the packaging bag includes a paper base material.

[0020] According to the above seventh aspect, compared with the case where the packaging bag is made of a resin film or the like, in a state where the packaging bag is opened along the perforation, the front portion and the rear portion can be made more upright with respect to the bottom portion. Therefore, the absorbent article can be taken out even more easily from the take-out opening.

Advantages of the Invention

[0021] According to the absorbent article package according to one aspect of the present invention, the absorbent article can be easily taken out from the take-out opening, and it is possible to prevent dust from entering through the take-out opening.

[Figure 3] It is a perspective view showing a state where the take-out opening is closed after the packaging bag is opened.

Modes for Carrying Out the Invention

[0023] Embodiments of the present invention will be described in detail below with reference to the drawings. In each drawing, unless otherwise specified, the same or corresponding components may be denoted by the same reference numerals and their descriptions may be omitted. In this specification, the stacking direction of the absorbent articles is the X direction, the direction perpendicular to the bottom surface is the Z direction, and the front-to-back direction of the absorbent article packaging (direction perpendicular to the XZ plane) is the Y direction. Also, the sealed side (+Z direction) of the absorbent article packaging is considered the top, and the bottom surface side (-Z direction) is considered the bottom.

[0024] Figure 1 is a perspective view of an absorbent article packaging 1 according to one embodiment, Figure 2 is a perspective view showing the packaging bag 2 in an opened state, and Figure 3 is a perspective view showing the packaging bag 2 in an opened state with the dispensing opening 27 closed. As shown in Figure 1, the absorbent article packaging 1 contains an absorbent article laminate 30, in which multiple absorbent articles 3 are stacked, housed in a packaging bag 2.

[0025] The absorbent articles 3 contained in the packaging bag 2 may be, for example, disposable diapers for babies or elderly care, sanitary napkins, etc. The absorbent articles 3 may be folded, and if they are folded, it is preferable that they be contained in the packaging bag 2 with the folds facing upwards (+Z direction) for ease of removal. The number of absorbent articles 3 contained is not particularly limited, but in the case of disposable diapers, for example, it may be 30.

[0026] Packaging bag 2 may include a paper base material as the packaging base material. The paper base material is obtained by papermaking a slurry containing raw pulp. The paper base material may consist of a single layer or multiple layers. Examples of raw pulp include softwood kraft pulp, hardwood kraft pulp, crushed wood pulp, thermomechanical pulp, chemothermetic pulp, and recycled paper pulp. These raw pulps can be used individually or in combination.

[0027] The basis weight of the paper substrate is 20 g / m². 2 ~120g / m 2 Preferably, it is 30 g / m 2 ~80g / m 2It is more preferable that it be 40g / m 2 ~60g / m 2 It is even more preferable that the basis weight of the paper substrate be 20 g / m². 2 ~120g / m 2 Therefore, even when the absorbent article 3 contained in the packaging bag 2 is a disposable diaper, the packaging bag 2 can have sufficient strength.

[0028] The thickness of the paper substrate is preferably 15 μm to 150 μm, more preferably 25 μm to 100 μm, and even more preferably 30 μm to 80 μm. A paper substrate thickness of 15 μm to 150 μm ensures that the packaging bag 2 has sufficient strength, even when the absorbent article 3 contained within the bag is a disposable diaper.

[0029] The packaging bag 2 may include a paper base material and a sealing layer laminated on the inner surface of the packaging bag 2 within the paper base material. By including the paper base material and the sealing layer, the packaging bag 2 can suppress the intrusion of moisture from the outside and prevent the absorbent article 3 from absorbing external moisture and deteriorating before use.

[0030] The seal layer preferably includes at least one of a heat seal layer and an adhesive layer. The heat seal layer may be composed of either a single layer or multiple layers. Examples of materials constituting the heat seal layer include polyethylene-based resins and polypropylene-based resins. Examples of polyethylene-based resins include high-pressure low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), medium-density polyethylene (MDPE), high-density polyethylene (HDPE), ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-ethyl acrylate copolymer (EEA), ethylene-methyl acrylate copolymer (EMA), ethylene-vinyl acetate copolymer (EVA), carboxylic acid-modified polyethylene, and their derivatives, as well as mixtures thereof. Examples of polypropylene-based resins include polypropylene (PP) homopolymer, random polypropylene (random PP), block polypropylene (block PP), chlorinated polypropylene, carboxylic acid-modified polypropylene, styrene acrylic acid, styrene butadiene latex, and their derivatives, as well as mixtures thereof.

[0031] The heat seal layer can be formed by coating using a known coating method. For example, coating machines such as a two-roll size press coater, gate roll coater, blade metering coater, rod metering coater, blade coater, air knife coater, roll coater, brush coater, kiss coater, squeeze coater, curtain coater, die coater, bar coater, gravure coater, etc. can be used.

[0032] The basis weight of the heat seal layer is preferably 2 ~115 g / m 2 and more preferably 2 ~75 g / m 2 and even more preferably 2 ~57 g / m 2 When the basis weight of the heat seal layer is 2 ~115 g / m 2As a result, even when the absorbent article 3 contained in the packaging bag 2 is a disposable diaper, the packaging bag 2 can have sufficient strength, and the packaging bag 2 can be easily opened along the perforations 26.

[0033] If the absorbent item 3 is a disposable baby diaper, the seal layer shall be made of high-pressure low-density polyethylene with a basis weight of 15 g / m², from the standpoint of the strength required for the packaging bag 2. 2 It consists of a heat-seal layer and linear low-density polyethylene, with a basis weight of 25 g / m². 2 It is preferable to have a heat-seal layer.

[0034] Examples of adhesives that make up the adhesive layer include ethylene-based adhesives, two-component curing urethane-based adhesives, polyester urethane-based adhesives, polyether urethane-based adhesives, acrylic-based adhesives, styrene-acrylic-based adhesives, polyester-based adhesives, polyamide-based adhesives, polyvinyl acetate-based adhesives, epoxy-based adhesives, and rubber-based adhesives.

[0035] The adhesive layer can be formed by coating using a known coating method, and a coating machine similar to the one used for coating the heat seal layer can be used.

[0036] The packaging bag 2 may include other layers in addition to the paper substrate and the sealing layer. Examples of these other layers include a water vapor barrier layer, an oxygen barrier layer, a printing layer, a light-shielding layer, and so on. These other layers can be provided, for example, between the paper substrate and the sealing layer, or on the outermost surface of the packaging bag 2, and may consist of one layer or two or more layers. The packaging bag 2 does not necessarily have to contain a paper substrate as its packaging material; for example, it may be made of a resin film or the like.

[0037] As shown in Figures 1 and 2, the absorbent article packaging 1 has a bottom portion 21, a front portion 22 and a rear portion 23, a pair of side portions 24 connected to the front portion 22 and the rear portion 23, and a sealing portion 25 to which the upper ends of the front portion 22 and the rear portion 23 are joined. Multiple absorbent articles 3 are stacked in the stacking direction (X direction) from one side portion 24 to the other side portion 24.

[0038] The absorbent article packaging 1 may further have seals on both sides. The side portion 24 may be formed integrally with the front portion 22 and the rear portion 23. The bottom portion 21 may have a gusset. Specifically, the packaging bag 2 may be a gusset bag in which the bottom material is folded to form a gusset, two rectangular base materials and the bottom material are sealed and joined, and then the edges on both sides of the two base materials are sealed, the absorbent article 3 is placed inside, and the upper ends of the front portion 22 and the rear portion 23 are sealed. Because the bottom portion 21 has a gusset, the absorbent article packaging 1 can stand upright stably even after the packaging bag 2 is opened at the perforations 26.

[0039] On the front portion 22, perforations 26 are formed along the stacking direction (X direction) of the absorbent article 3, above the upper end 31 of the absorbent article stack 30 (+Z direction), on the bottom portion 21 side (-Z direction) from the seal portion 25. The ends of the perforations 26 are located outside a position 30 mm inward from the end of the absorbent article stack 30 in the X direction, and are 3% or more of the total length of the perforations 26. Here, the total length of the perforations 26 means the length from the cut portion (cut portion) on one end to the cut portion on the other end. With this configuration, by opening the packaging bag 2 in the vertical direction along the perforations 26, as shown in Figure 2, an opening 27 is formed above the upper end 31 of the absorbent article stack 30, exposing the upper end 31 of the absorbent article stack 30 in the X direction, and the upper end of the absorbent article 3 contained in the packaging bag 2 is exposed. Therefore, the absorbent article 3 can be easily removed from the dispensing opening 27 by pinching its upper end. Furthermore, after opening the packaging bag 2, the packaging bag 2 covers everything except the upper end 31 of the absorbent article stack 30, and as shown in Figure 3, the dispensing opening 27 can be closed by overlapping the upper portion 28 of the packaging bag 2, which is located above the perforations 26, with the outer surface of the front portion 22, which is located below the perforations 26. Thus, it is possible to prevent waste from entering through the dispensing opening 27.

[0040] Furthermore, by ensuring that the distance L1 between the end of the perforation 26 and the edge of the front portion 22 in the X direction is 3% or more of the total length of the perforation 26, it is possible to suppress the tearing of the packaging bag 2 starting from the end of the perforation 26 when the absorbent article packaging 1 is packaged during the distribution process or when it is carried by the user. In addition, because the perforation 26 is formed only on the front portion 22 and the end of the perforation 26 is separated from the edge of the front portion 22 in the X direction, no torn pieces of the packaging bag 2 are generated after the packaging bag 2 is opened, and the absorbent article packaging 1 has excellent usability.

[0041] The distance L1 between the end of the perforation 26 and the edge of the front portion 22 in the X direction is preferably 15 mm or more. This further suppresses the tearing of the packaging bag 2 starting from the end of the perforation 26 when the absorbent article packaging 1 is packed during distribution or carried by the user, and also allows the absorbent article 3 to be easily removed from the opening when using it.

[0042] As shown in Figure 2, when the packaging bag 2 is opened along the perforations 26, it is preferable that the front portion 22 and the rear portion 23 are upright relative to the bottom portion 21. This prevents the front portion 22 and the rear portion 23, which protrude above the absorbent article 3, from covering the upper end of the absorbent article 3 when it is removed, and maintains that the upper end of the absorbent article 3 contained in the packaging bag 2 is exposed. Therefore, the absorbent article 3 can be removed more easily from the opening 27.

[0043] When the packaging bag 2 contains a paper base material, compared to when the packaging bag 2 is made of a resin film or the like, the front portion 22 and the rear portion 23 can be made more upright relative to the bottom portion 21 when the packaging bag 2 is opened at the perforations 26. Therefore, the absorbent article 3 can be removed more easily from the opening 27. Furthermore, from the viewpoint of reducing environmental impact, there is a demand to replace resin packaging bags with paper packaging bags, and by including a paper base material in the packaging bag 2, the absorbent article packaging 1 can reduce its environmental impact.

[0044] Preferably, the length of the tie portion (non-cut portion) of the perforation 26 is 1.0 mm to 15 mm, and the length of the cut portion (cut portion) of the perforation 26 is 0.5 mm to 2.0 mm. More preferably, the length of the tie portion of the perforation 26 is 1.5 mm to 10 mm, and the length of the cut portion of the perforation 26 is 0.7 mm to 1.6 mm. Even more preferably, the length of the tie portion of the perforation 26 is 2.0 mm to 5.0 mm, and the length of the cut portion of the perforation 26 is 0.9 mm to 1.2 mm. Since the length of the tie portion of the perforation 26 is 1.0 mm to 15 mm, and the length of the cut portion of the perforation 26 is 0.5 mm to 2.0 mm, even if the packaging bag 2 has a paper base material and a sealing layer, it can be easily opened to both ends of the perforation 26. As a result, an opening 27 is formed that exposes the upper end 31 of the absorbent article laminate 30 in the X direction, and the upper end of the absorbent article 3 contained in the packaging bag 2 is exposed. Therefore, the absorbent article 3 can be easily removed from the opening 27 by pinching its upper end.

[0045] The distance L2 between the perforation 26 and the upper end of the packaging bag 2 is preferably 30% to 70% of the length L3 of the absorbent article laminate 30 in the direction along the side portion 24 (Y direction), more preferably 35% to 60%, and even more preferably 40% to 55%. By setting the distance L2 between the perforation 26 and the upper end of the packaging bag 2 to 30% to 70% of the length L3 of the absorbent article laminate 30 in the Y direction, the area of ​​the upper portion 28 located above the perforation 26 of the packaging bag 2 can be made sufficiently large after the packaging bag 2 is opened. Therefore, when the upper portion 28 is overlapped with the outer surface of the front portion 22 located below the perforation 26, the overlapping area can be made larger. Thus, the dispensing opening 27 can be kept closed for a longer period of time, and the entry of waste from the dispensing opening 27 can be further suppressed.

[0046] The distance L4 between the perforation 26 and the upper end 31 of the absorbent article laminate 30 is preferably 20 mm to 80 mm, more preferably 30 mm to 70 mm, and even more preferably 40 mm to 60 mm. By setting the distance L4 between the perforation 26 and the upper end 31 of the absorbent article laminate 30 to 20 mm to 80 mm, interference by the front portion 22 protruding above the absorbent article laminate 30 can be suppressed when removing the absorbent article 3 after opening the packaging bag 2, and the absorbent article 3 can be removed more easily from the dispensing opening 27.
