Description

The present invention relates to individually packaged absorbent articles.

In general, absorbent articles such as sanitary napkins, panty liners, and incontinence pads are provided in a state of being individually wrapped with wrapping sheets for reasons such as hygienic storage and portability. . Such a packaged absorbent article (also referred to as an individually packaged absorbent article or an individual package of absorbent articles) includes an absorbent article placed inside a packaging sheet, and the packaging sheet together with the absorbent article. A well-known configuration is that which is folded inward and then sealed at both edges.

The wrapping sheet originally has the function of wrapping absorbent articles before use as described above, but it is also used when discarding used absorbent articles. At that time, the user generally wraps the used absorbent article with a wrapping sheet, and the wrapping sheet is opened by fixing the ends of the wrapping sheet with a fastening tape attached to many individually packaged absorbent articles. I try not to Therefore, constructions of fastening tapes and packaging sheets that are easy to use even when used absorbent articles are discarded have been studied.

For example, Patent Literature 1 discloses an absorbent article in which a fastening tape consisting of a base portion fixed to an unsealing portion of a packaging sheet and a fastening portion having an adhesive layer is provided, and the fastening tape is attached to the upper surface of the base portion. A configuration is described in which the adhesive layer of the attachment part is attached by releasably adhering, and the packaging sheet in which the used product is wrapped can be attached by the attachment part.

JP-A-2004-49262

However, the fastening tape is a separate member from the packaging sheet. Therefore, depending on the type of attachment of the fastening tape to the packaging sheet, the material of the packaging sheet, etc., the fastening tape may come off from the packaging sheet when the individually packaged absorbent article is opened. can be dropped on the floor or lost. Further, depending on the size of the fastening tape, it may not be possible to sufficiently fasten the ends of the packaging sheet when discarding the used absorbent article. As a result, the packaging sheet in which the used absorbent article is wrapped may be easily opened, and the used absorbent article may be exposed from the packaging sheet and may not be hygienically discarded. Therefore, there is a demand for a structure that can securely fasten the packaging sheet that wraps the used absorbent article.

In view of the above, one aspect of the present invention provides an individual package having a configuration that allows the packaging sheet that wraps the used absorbent article to be securely attached when the packaging sheet is utilized when disposing of the used absorbent article. An object of the present invention is to provide an absorbent article.

A first aspect of the present invention is an individually packaged absorbent article including a packaging sheet and an absorbent article wrapped by the packaging sheet, wherein the packaging sheet corresponds to the front-rear direction of the absorbent article. It has a first direction and a second direction perpendicular to the first direction, and at least one end portion of the first direction, a part of the packaging sheet is folded back to form a folded portion, and the folded portion is formed. An adhesive is disposed between the portion and a portion of the packaging sheet facing the folded portion, the folded portion can be unfolded, and the unfolding exposes the adhesive.

In the first aspect, the pressure-sensitive adhesive disposed between the folded portion of the packaging sheet and the portion facing the folded portion (facing portion) is applied to the packaging sheet after the used absorbent article is wrapped with the packaging sheet. available for fastening. For example, when replacing the absorbent article, the user may use the packaging sheet left after removing the new absorbent article so that the folded portion formed at the end of the packaging sheet covers the used absorbent article last. Wrap the absorbent article. At that time, the folded portion is opened to expose the adhesive, and the adhesive adheres the end portion of the packaging sheet to another area of the packaging sheet. In this way, since the adhesive directly provided on the packaging sheet is used for the attachment of the packaging sheet, the attachment means is not lost and the packaging sheet can be attached more securely. can be done. Furthermore, since the adhesive is placed and protected between the folded portion and the opposing portion until it is used, it is possible to prevent the adhesive strength from decreasing.

Moreover, according to this aspect, it is not necessary to use fastening tapes for disposal of used absorbent articles as in the conventional configuration. Therefore, the role of the fastening tape can be mainly or exclusively to fasten the packaging sheet of the individually packaged absorbent article before use, and the once peeled fastening tape can be reused when disposing of the used absorbent article. The fastening tape can be designed without considering the Alternatively, the fastening tape can be omitted from the individually packaged absorbent article.

In a second aspect of the present invention, the packaging sheet has an inner surface on which the absorbent article is placed and an outer surface opposite to the inner surface, the folded portion is folded back on the inner surface, and the folded portion is folded back on the inner surface. The inner surface of the portion is not peeled, and the inner surface of the portion facing the folded portion is peeled.

According to the second aspect, the folded portion is folded back on the inner surface of the packaging sheet, and the adhesive is arranged on the inner surface of the packaging sheet. Therefore, when the used absorbent article is wrapped with the wrapping sheet, the adhesive can face the outer surface of the wrapping sheet. Here, the surface condition of the outer surface of the packaging sheet (surface material, presence or absence of surface treatment, etc.) can be freely determined compared to the inner surface on which the absorbent article is placed, and the outer surface of the packaging sheet is adhered by the adhesive. Alternatively, it is easy to maintain a state in which it is easy to fix. Therefore, the attachment of the packaging sheet can be made more reliable.

In addition, since the inner surface of the facing portion that has undergone the peeling treatment can be easily separated from the adhesive, the adhesive can be fixed to the inner surface of the folded portion when the folded portion is unfolded. As a result, the position of the adhesive becomes closer to the edges of the packaging sheet, and the packaging sheet can be used more widely to wrap the used absorbent article.

A third aspect of the present invention is that the packaging sheet has a first region including a first end in the first direction and a second region including a second end opposite to the first end, The first region and the second region are folded such that the first region overlaps the outer surface of the second region, and both edges in the second direction are sealed along the first direction, The folded portion is a region including the first end of the first region.

According to the third aspect, the first region including the folded portion is arranged outside before use of the individually packaged absorbent article, and when the individually packaged absorbent article is unsealed, the user can fold the absorbent article. The first region can be peeled off by holding the vicinity of the part. Since the folded portion is folded back and the end portion is doubled, the first region can be easily gripped and the package can be opened smoothly.

In a fourth aspect of the present invention, the inner surfaces of both edges in the second direction of the packaging sheet have a release-treated portion and a non-release-treated portion, and A release processing portion is provided in a range including the folded portion in plan view in the folded state.

In general, when a seal portion is formed on a peel-treated portion of a packaging sheet, the bonding strength of the seal portion tends to be weak. On the other hand, according to the fourth aspect, the bonding strength can be improved by providing non-peeling treated portions on both edges of the packaging sheet. In addition, by making the portion that overlaps with the folded portion in plan view when folded into a peeling treated portion, the bonding strength of the portion to which force is applied at the start of opening can be weakened, making it easier to open. Therefore, the unsealing operation can be made easier, and the sealing before unsealing can be ensured to enhance the airtightness.

In a fifth aspect of the present invention, the adhesive is arranged along the second direction in plan view over 10% or more of the length of the packaging sheet in the second direction.

According to the fifth aspect, the adhesive is widely arranged along the second direction of the packaging sheet. Therefore, when the used absorbent article is disposed of, if the packaging sheet is wrapped around the used absorbent article in the first direction, the adhesive will extend widely in the direction perpendicular to the winding direction, and the packaging sheet will be stretched. The ends can be fastened in a wide range. As a result, the end portion of the wrapped packaging sheet is less likely to come off, and the used absorbent article can be wrapped more securely.

In a sixth aspect of the present invention, the folded portion has a convex portion protruding in the first direction, and the convex portion can be gripped when the folded portion is unfolded.

According to the sixth aspect, the protrusion can be gripped when unfolding the folded portion, so the folded portion can be unfolded more easily.

In a seventh aspect of the present invention, the absorbent article is arranged such that the front-rear direction of the absorbent article is along the first direction and the width direction is along the second direction, and the packaging Between the sheet and the absorbent article, a pressure-sensitive adhesive for absorbent articles is arranged to serve as a slip prevention portion when the absorbent article is worn, and the pressure-sensitive adhesive for absorbent articles is arranged along the second direction. It has an elongated shape.

According to the seventh aspect, the pressure-sensitive adhesive disposed between the folded portion and the facing portion and the pressure-sensitive adhesive for absorbent articles can be formed along the same direction (second direction). At the time of manufacturing the absorbent article, both can be formed at the same timing using the same apparatus. Therefore, it is possible to increase the operational efficiency of manufacturing individually packaged absorbent articles.

According to one aspect of the present invention, an individually packaged absorbent article having a configuration in which a packaging sheet that wraps a used absorbent article can be securely fastened when the packaging sheet is used for disposal of the used absorbent article. can be provided.

In addition, in each drawing, unless there is a particular description, the same reference numerals may be attached to the same or corresponding configurations, and the description thereof may be omitted. Also, the drawings are schematic to aid understanding of the invention.

FIG. 1 shows a plan view of an individually packaged absorbent article 100. As shown in FIG. Further, FIG. 2 shows a schematic diagram of a cross section taken along the line II of FIG. As shown in FIGS. 1 and 2, an individually packaged absorbent article 100 according to this embodiment includes a packaging sheet 10 and an absorbent article 1 individually packaged with the packaging sheet 10 . The individually packaged absorbent article 100 is one in which one absorbent article 1 is wrapped in one packaging sheet 10, but may be one in which a plurality of absorbent articles are wrapped.

The absorbent article 1 wrapped by the packaging sheet 10 in this embodiment may be a flat and elongated article that is worn so as to face the outlet for bodily fluids (menstrual blood, vaginal discharge, urine, etc.). The packaging sheet 10 also has an elongated shape in the unfolded state, similar to the shape of the absorbent article 1, and may have, for example, a rectangular shape, an oblong shape, or the like. When the absorbent article 1 is wrapped with the packaging sheet 10, the absorbent article 1 is placed on the inner surface of the packaging sheet 10, and both are folded into three or more, so that the absorbent article 1 is placed inside the packaging sheet 10. hide. Furthermore, both edges in the direction perpendicular to the folding direction are sealed to form seal portions 18 , 18 . The form of individual packaging in which both edges in the direction perpendicular to the folding direction are sealed after being folded in one direction is preferable because the absorbent article can be hygienically accommodated in a simple procedure. The packaging format in this embodiment will be described in more detail later.

In this specification, the longitudinal direction of the elongated packaging sheet 10 is defined as a first direction D1, and the width direction orthogonal to the longitudinal direction is defined as a second direction D2. In an individually packaged state, the first direction D1 is the longitudinal direction of the absorbent article 1, that is, the front-rear direction corresponding to the front-rear direction of the wearer's body when worn, and the second direction D2 is the width direction of the absorbent article 1. But also.

Specific examples of the absorbent article 1 packaged in this form may be a sanitary napkin, a panty liner (a sheet for vaginal discharge), a pad for light incontinence, and the like. Among others, this form is particularly suitable for sanitary napkins that many users wrap in a wrapping sheet and throw away. The absorbent article 1 may have a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent body disposed between the topsheet and the backsheet.

As the back sheet, a sheet material having at least water impermeability, such as an olefin resin sheet such as polyethylene or polypropylene, can be used. A laminated nonwoven fabric obtained by laminating a nonwoven fabric on a polyethylene sheet or the like, or a laminated sheet of a nonwoven fabric in which a waterproof film is interposed to substantially ensure liquid impermeability can be used. Also, a material having moisture permeability may be used.

As the surface sheet, a perforated or non-perforated nonwoven fabric, a porous plastic sheet, or the like is preferably used. The material fibers that make up the nonwoven fabric include, for example, olefins such as polyethylene and polypropylene, synthetic fibers such as polyester and polyamide, regenerated fibers such as rayon and cupra, blended fibers thereof, and natural fibers such as cotton. It can be used in combination of two or more.

The absorber is not limited as long as it is a material that can absorb and retain bodily fluids, but it preferably contains cotton-like pulp and a water-absorbent polymer. As the absorbent polymer, superabsorbent polymer (SAP), superabsorbent fiber (SAF) and combinations thereof can be used. The pulp includes chemical pulp obtained from wood, cellulose fibers such as dissolving pulp, and artificial cellulose fibers such as rayon and acetate.

The thickness of the absorber may be 0.5-25 mm. The absorbent body can also have a structure in which a region corresponding to the body fluid outlet (body fluid outlet corresponding region) and a region behind the body fluid outlet corresponding region facing the groove of the buttocks are swollen. The absorbent body has dimensions and a shape that does not protrude from the topsheet and the backsheet, and the outer edges of the backsheet and the topsheet are bonded with an adhesive such as hot melt or heat-sealed at the front and rear edges of the absorbent body. , are joined by an adhesive means such as an ultrasonic seal.

In addition, side nonwoven fabrics may be provided along the longitudinal direction at both ends in the width direction on the outer sides of the absorbent body. As the side nonwoven fabric, a water repellent nonwoven fabric or a hydrophilic treated nonwoven fabric can be used. The absorbent article 1 may have wings extending laterally, and such wings may be formed by joining a side sheet and a back sheet.

In addition, the non-skin side of the absorbent article 1 (the side facing the underwear when worn) may be provided with an anti-slip portion for preventing slippage from the underwear when the absorbent article 1 is attached to the underwear. (not shown in FIGS. 1 and 2).

The total length of the absorbent article 1 can be 140 to 430 mm, and the width of the absorbent article 1 (the width of the main body excluding the wings when the absorbent article 1 has wings) can be 50 to 130 mm.

The dimensions of the packaging sheet 10 depend on the size and shape of the absorbent article 1 to be packaged. The length (sometimes simply referred to as length) can be 100 to 460 mm, and the length (sometimes simply referred to as width) in the second direction (lateral direction) D2 can be 70 to 250 mm. .

The material constituting the packaging sheet 10 is not particularly limited, and may be a resin film, nonwoven fabric, paper, or the like. Of these, it is preferable to use a resin film because it is easy to process the surface and is less likely to be damaged when the folded portion is expanded (detailed later). In addition, when a resin film is used, even if the packaging sheet is printed, the outlines of the printed characters and patterns become clearer, and the coloration of the coloring agent also improves, which improves the design of the packaging sheet. can be made

When a resin-made fill is used for the packaging sheet 10, examples of the resin to be used include polyolefins such as polypropylene and polyethylene, polyester, polyvinyl alcohol, and the like. As the resin film, a stretched one is preferable. Moreover, the resin film may be either a non-breathable film or a breathable film.

The use of a non-woven fabric for the packaging sheet 10 is preferable in that the texture, flexibility and the like can be improved. The nonwoven fabric to be used is preferably a meltblown nonwoven fabric, a spunbond nonwoven fabric, or the like, and it is also possible to use a laminate obtained by combining a plurality of layers of these nonwoven fabrics. Moreover, fibers constituting the nonwoven fabric may be polyolefins such as polypropylene and polyethylene, polyamides such as polyester and nylon, and the like.

It should be noted that the use of paper for the packaging sheet 10 is preferable in that it reduces the burden on the environment at the time of disposal and can impart a unique texture, for example, a gentle impression of the appearance and feel of a natural material. In the present specification, the term "paper" can refer to a sheet made by agglutinating plant fibers or other fibers with a glue. In particular, it can refer to a material mainly composed of vegetable fibers (pulp), for example, a material containing 50% or more, preferably 80% or more, vegetable fiber of the contained fibers. The types of pulp contained in the paper may include wood pulp, non-wood pulp, and waste paper pulp, which may be either mechanical pulp or chemical pulp. Additives may be added to the paper. Further, specific examples of paper used for the packaging sheet 10 include various types of paper such as western paper, Japanese paper, processed paper, and synthetic paper. In addition, unprocessed or processed paper conventionally used for other purposes, such as newsprint, printing paper (including high-quality paper), writing paper, drawing paper, wrapping paper, tissue paper, miscellaneous paper, etc. can also be used as When thin paper is used, it may be thin imitation paper, Indian paper, rice paper, glassine paper, tissue paper, toilet paper, filter paper, or the like.

As the packaging sheet 10, one packaging sheet 10 may be a single-layer sheet made of the materials described above, or one packaging sheet 10 may be made by laminating a plurality of layers made of different materials. It may be a laminated sheet consisting of

Next, referring to FIGS. 3 to 5 together with FIGS. 1 and 2, the individual packaging form of the absorbent article 1 will be described. FIG. 3 shows the packaging sheet 10 in a completely unfolded state (folded or unfolded state) before the absorbent article 1 is placed, from the inner surface IF, that is, the side on which the absorbent article 1 is placed. 1 shows a plan view seen from . FIG. 3 shows the initial stage before the packaging sheet 10 is placed in the manufacture of individually packaged absorbent articles, and can also show a state in which the folded portion (described later) is once folded back and opened again.

As shown in FIG. 3, the packaging sheet 10 has a first region R1 including one end 11 in the first direction D1 and a second region R2 including the other end 12 opposite to the one end. A third region R3 is provided between the region R1 and the second region R2. When the packaging sheet is folded 10 times for packaging the absorbent article, the first region R1 is folded along the second direction D2 along the fold line L1, and the second region R2 is folded along the second direction D2. It is folded back at L2.

In this embodiment, the end of the packaging sheet 10 is folded back in the first direction D1 on the one end 11 side. This folded portion is the folded portion Re. As shown in FIG. 1, the folded portion Re is a portion included in the first region R1, and is a portion folded toward the inner surface IF along the folded portion folding line Le along the second direction D2. FIG. 4 shows the state after the folded portion Re has been folded. The folding of the folded portion Re hides the inner surface IF of the two surfaces of the folded portion Re, leaving only the outer surface OF visible.

As shown in FIG. 3, the adhesive 8 is provided on the inner surface IF of the folded portion Re before being folded. It is sandwiched between the portion (opposing portion) Rf of the packaging sheet 10 that faces the folded portion Re. That is, the adhesive 8 is not exposed when the folded portion Re is folded.

The adhesive 8 is used to fasten the ends of the packaging sheet 10 when wrapping the used absorbent article with the packaging sheet 10 removed from the absorbent article after the individually packaged absorbent article is opened. (described below with reference to FIG. 6). The type of the adhesive 8 is not particularly limited, but a hot-melt type adhesive is preferable because it is easy to handle. A styrenic polymer, a tackifier, a plasticizer, and a combination thereof can be used as the main component of the adhesive 8 . Styrene-based polymers include styrene-ethylene-butylene-styrene block copolymers, styrene-butylene-styrene block copolymers, styrene-isobutylene-styrene copolymers, styrene-butadiene-styrene block copolymers, and the like. , one or more of these can be used. Among these, styrene-butadiene-styrene block copolymers are preferred in terms of good thermal stability. Moreover, as a tackifier and a plasticizer, a solid thing can be used at normal temperature. Examples of tackifiers include C5-based petroleum resins, C9-based petroleum resins, dicyclopentadiene-based petroleum resins, rosin-based petroleum resins, polyterpene resins, and terpene phenol resins. Examples of plasticizers include monomer plasticizers such as triflesyl phosphate, dibutyl phthalate, and dioctyl phthalate, as well as polymer plasticizers such as vinyl polymers and polyesters.

The method of providing the adhesive 8 on the packaging sheet 10 is not particularly limited, but examples thereof include melt coating using a hot melt coater. For example, coating devices such as gravure coaters, spray coaters, spiral guns, bead guns, etc. can be used.

In the example shown in FIG. 3, the inner surface IF of the folded portion Re is not subjected to peeling treatment, while the facing portion Rf is subjected to peeling treatment (mold release treatment). Further, in the illustrated example, the peeling treatment is applied to the region other than the folded portion Re. In the drawing, the portion subjected to the peeling treatment is indicated as the peeling treated portion 21 and the portion not treated as the peeling treated portion is indicated as the non-peeling treated portion 22 . The release treatment is a surface treatment for weakening the bonding force with the adhesive. Therefore, when the adhesive 8 comes into contact with the peeling treated portion 21, the adhesive 8 is easily peeled off from the peeling treated portion 21, whereas when the adhesive 8 comes into contact with the non-peeling treated portion 22, the adhesive 8 does not peel off It is difficult to peel off from the processing portion 22 . In the example shown in FIG. 3 , the folded portion Re is the non-peeling treated portion 22 and the facing portion Rf is the peeling treated portion 21 . Therefore, when the folded portion Re on which the adhesive 8 is arranged is folded back and overlaid on the opposing portion Rf as shown in FIG. , the adhesive 8 remains on the folded portion Re, which is the non-peeling portion 22, and does not adhere to the facing portion Rf, which is the peeling portion 21. FIG.

Thus, in this embodiment, the end portion of the packaging sheet 10 in the first direction D1 is folded back to form the folded portion Re, and the adhesive 8 is arranged between the folded portion Re and the facing portion Rf. . The state in which the adhesive 8 is arranged between the folded portion Re and the facing portion Rf is maintained in the individually packaged absorbent article 100 before opening (FIGS. 1 and 2). When the packaging sheet 10 is used for disposal of used absorbent articles, the adhesive 8 can be exposed by unfolding the folded portion Re. The exposed adhesive 8 can be used to secure the packaging sheet 10 after wrapping it around the used absorbent article.

In addition, if the adhesive 8 is arranged between the folded portion Re and the facing portion Rf in a state where the folded portion Re is folded back, and if the adhesive 8 can be exposed when the folded portion Re is unfolded, the adhesive 8 can be applied. The place where the agent 8 is applied when the packaging sheet 10 is manufactured may be the facing portion Rf instead of the folded portion Re as shown in FIG. Even if the adhesive 8 is applied to the facing portion Rf, if the facing portion Rf is the release treated portion 21 and the folded portion Re is the non-peeled portion 22, the adhesive 8 is peeled off from the facing portion Rf and folded back. Move to part Re.

Furthermore, in the example shown in FIGS. 3 and 4, the inner surface IF of the folded portion Re is the non-peeled portion 22 and the inner surface IF of the facing portion Rf is the peeled portion 21, but the folded portion Re is peeled. However, the peeling treated portion 21 may be formed at the folded portion Re, and the facing portion Rf may not be peeled and may be the non-peeling treated portion 22 . Then, the adhesive 8 is placed on at least one of the folded portion Re and the opposing portion Rf, and the folded portion Re is folded back to overlap the opposing portion Rf, whereby the adhesive is applied between the folded portion Re and the opposing portion Rf. 8 can be arranged. In that case, when the folded portion Re is unfolded again, the adhesive 8 is fixed to the facing portion Rf where the non-peeling treated portion 22 is formed, and the adhesive 8 does not remain on the folded portion Re.

Thus, in this embodiment, one of the folded portion Re and the facing portion Rf may be formed with the peeling treated portion 21 and the other may be the non-peeling treated portion 22, but the peeling treated portion 21 is formed at the facing portion Rf. It is preferable that As a result, when the folded portion Re is unfolded, the adhesive 8 is fixed to the folded portion Re located at the end in the first direction D1, and is wrapped around the used absorbent article when the used absorbent article is discarded. This is preferable because the area of the portion of the packaging sheet 10 is increased. Note that the peeling treated portion 21 may be formed on both the folded portion Re and the facing portion Rf. In that case, it is preferable that one of the folded portion Re and the facing portion Rf has a larger bonding force with the adhesive 8 than the other. In that case, when the folded back portion Re is unfolded, the adhesive 8 remains on the side with the greater bonding force.

Further, the folded portion Re may be folded back toward the outer surface OF instead of being folded toward the inner surface IF as shown in FIGS. 1 to 4 . Then, the adhesive 8 is arranged between the outer surface of the folded portion Re and the outer surface of the facing portion Rf facing the folded portion Re. In that case, by forming the peeling treatment portion 21 on either the outer surface of the folded portion Re or the outer surface of the facing portion Rf, when the folded portion Re is unfolded again when the used absorbent article is discarded, the peeling treatment can be performed. The adhesive 8 remains on the part where the part 21 is not formed (the part serving as the non-peeling treated part 22), and a fixed state can be obtained.

The release treatment applied to the packaging sheet 10 may be, for example, a treatment of applying a liquid release agent (mold release agent) containing silicone-based resin, paraffin-based resin, fluororesin, or the like. The peeling treatment can be performed by a known coating process such as spraying and roll coating. Alternatively, a sheet containing the component of the release agent may be adhered to a predetermined area of the packaging sheet 10 .

In the manufacture of individually packaged absorbent articles, as shown in FIG. 4, the absorbent article 1 is placed on the packaging sheet 10 with the folded portion Re folded back to the inner surface IF. FIG. 5 shows a plan view of a state in which the absorbent article 1 is placed on the inner surface IF of the packaging sheet 10. As shown in FIG. In FIG. 5, the absorbent body 4 included in the absorbent article 1 is also illustrated. As shown in FIG. 5, the absorbent article 1 may be arranged over the first region R1, the third region R3, and the second region R2. At this time, the absorbent article 1 may or may not be overlaid on the folded portion Re.

As shown in FIG. 5 , from the state where the absorbent article 1 is superimposed on the packaging sheet 10, the packaging sheet 10 and the absorbent article 1 are folded along the folding line L2 along the second direction D2, for example, in the second region R2. After that, the first region R1 is folded along the folding line L1 along the second direction D2. At that time, the first region R1 is made to overlap the outer surface of the second region R2. By folding toward the inner surface IF in the first direction D1, a compact individually packaged absorbent article 100 as shown in FIGS. 1 and 2 is obtained. After folding, both edges in the second direction are sealed by heat sealing, ultrasonic sealing, or mechanical means (such as embossing rollers) to form seals 18,18. It is preferable that the seal portions 18, 18 do not overlap the adhesive 8 described above. The seal portions 18, 18 are preferably formed within a range of 3 to 10 mm from the edge in the second direction D2.

1 and 2, the individually packaged absorbent article 100 may be three-folded (three-folded), but an absorbent article longer in the first direction D1 is individually packaged. For this reason, it can be folded in four or more. When folding in four or more, for example, before folding the second region R2, within the second region R2, that is, between the second folding line L2 and the other end 12 in the first direction D1, in the second direction D2 The ends can be pre-folded on the inner surface IF or the outer surface OF along a third fold line along.

Further, when the absorbent article 1 has wings, the wings are folded in advance toward the skin surface side (top sheet side) of the absorbent article 1, and then the first region R1 and the second region R2 are folded. .

When unpacking the individually packaged absorbent article 100, the user puts his or her finger between the first region R1 and the second region R2 and folds the outer edge of the first region R1, i.e., the folded portion. By gripping the vicinity of the line Le, the first region R1 can be peeled off from the second region R2. Even in this case, since the adhesive 8 is placed between the folded portion Re and the facing portion Rf and protected, there is no concern that the adhesive 8 will stick to the user's hands when the package is opened.

The packaging sheet 10 left after the absorbent article 1 is removed by unsealing the individually packaged absorbent article 100 can be used to wrap and dispose of the used absorbent article as described above. An example of use of the packaging sheet 10 is shown in FIG.

As shown in FIG. 6, the used absorbent article 1a is usually rolled up in the longitudinal direction (front-to-rear direction), and the rolled up used absorbent article 1a is provided with a newly opened unit for replacement of the absorbent article. Wrap with the packaging sheet 10 for the absorbent article. At this time, the used absorbent article 1a is placed on the end of the inner surface IF of the packaging sheet 10 opposite to the side where the folded portion Re is formed (the end on the side of the other end 12 in the first direction D1). Wrapping the packaging sheet 10 is preferred. As shown in FIG. 6, after wrapping the packaging sheet 10 around the used absorbent article 1a to some extent in the first direction D1, the folded back portion Re is unfolded to expose the adhesive 8. As shown in FIG. Then, the packaging sheet 10 is further wound, and the adhesive 8 is brought into contact with the portion of the packaging sheet 10 other than the folded portion Re, and the end of the packaging sheet 10 is fixed. The timing of unfolding the folded portion Re may be before, after, or during the winding of the packaging sheet 10 around the used absorbent article 1a.

In the conventional configuration, the user usually uses the fastening tape when disposing of the used absorbent article. However, since the fastening tape is separate from the packaging sheet, there is a possibility that it may come off during the opening operation of the absorbent article or while the used absorbent article is being wrapped, and fall to the floor or disappear. There is On the other hand, in this embodiment, since the adhesive 8 is applied and fixed to the packaging sheet 10, there is no possibility that the adhesive 8 will be lost. Further, the adhesive 8 in this embodiment is disposed between the folded portion Re and the facing portion Rf until the folded portion Re is opened as described above, and is protected from the outside without being exposed to the outside. That is, since it is used for the first time when the used absorbent article is discarded, the adhesive strength is maintained until it is needed at the time of disposal.

Furthermore, since the conventional fastening tape is attached to the packaging sheet of the individually packaged absorbent article before it is opened, the adhesive surface of the fastening tape can be reused when the used absorbent article is discarded. will do. Therefore, the adhesive strength may be reduced. On the other hand, in the present embodiment, the adhesive 8 provided directly on the packaging sheet 10 is used instead of the adhesive surface of the fastening tape for disposal of the used absorbent article 1a, so the fastening tape is used. A possible reduction in adhesive strength is also prevented. Therefore, in this embodiment, it is also possible to adopt a configuration in which no fastening tape is provided. As a result, the number of types of materials used can be reduced and the complexity of the manufacturing process can be suppressed, so that the operational efficiency can be improved. Alternatively, even if the configuration is provided with a fastening tape, there is no need to excessively increase the adhesive force of the fastening tape or increase the width in consideration of reuse at the time of disposal, and before and after opening. The fastening tape can be designed so that the function of time can be exhibited preferentially.

Note that if the fastening tape is not provided, the user who recognizes the fastening tape as a mark of the unsealing location may be confused as to where to hold to unseal. Therefore, in this embodiment, the vicinity of the folding line Le in the first region R1 of the individually packaged absorbent article 100 may be colored or printed with characters to make the opening position conspicuous.

On the other hand, when the fastening tape is provided, for example, in the individually packaged absorbent article 100 shown in FIG. It may be applied over the outer surface. As a result, it is possible to prevent unintentional opening of the individually packed absorbent article 100 due to unintentional insertion of a finger or an object between the first region R1 and the second region R2 before use. . In addition, the first region R1 can be lifted from the second region R2 by holding the fastening tape when unsealing. Such fastening tapes can be designed without considering their use at the time of disposal.

As shown in FIG. 6 and also as shown in FIGS. 3 and 4, the adhesive 8 is preferably formed according to the second method D2. For example, it preferably has a rectangular elongated shape as shown. Since the adhesive 8 has a shape along the second direction D2, the adhesive is applied in a direction perpendicular to the first direction D1, which is the winding direction when the packaging sheet 10 is wrapped around the used absorbent article 1a and fixed. 8 extends, the end of the packaging sheet 10 can be fastened in a wide range along the axial direction of the substantially cylindrical used absorbent article 1a. Therefore, it is possible to reduce the possibility that the packaging sheet 10 that has once been attached is peeled off.

The adhesive 8 may be arranged over preferably 10% or more, more preferably 30% or more, and even more preferably 50% or more of the length of the packaging sheet 10 in the second direction D2. The longer the length of the adhesive 8 in the second direction D2, the wider the range in which the packaging sheet 10 can be attached, which is preferable. Moreover, it is preferable that the adhesive 8 is larger than the width or length in the second direction of the absorbent article 1 to be packaged (when the absorbent article has wings, the width of the main body excluding the wings). However, the formation range of the adhesive 8 is preferably a range that is not formed on the seal portions 18, 18 (FIG. 1) of the individually packaged absorbent article 100. FIG. In this way, the adhesive 8 can be formed over a wide range along the second direction D2, unlike the fastening tape whose width (the length in the second direction D2) is limited.

As shown in FIGS. 3 and 6, the adhesive 8 is preferably formed at a position spaced apart from both edges of the folded portion Re in the first direction D1. The distance d1 ( FIG. 3 ) from the free edge of the edge of the folded portion Re in the first direction D1 to the adhesive 8, that is, the distance d1 ( FIG. 3 ) of the folded portion Re in the first direction D1 away from the folding line Le of the folded portion Re The distance from the edge (one end 11 of the packaging sheet 10) to the adhesive 8 is preferably 3 to 7 mm. Further, the distance d2 ( FIG. 3 ) from the edge of the folded portion Re in the first direction D1 at the boundary position with the adjacent facing portion Rf to the adhesive 8, that is, the folded portion fold of the folded portion Re The distance from the line Le to the adhesive 8 is preferably 3 to 7 mm. Also, the width of the adhesive 8, that is, the length in the first direction D1 is preferably 2 to 5 mm. Note that the width da (FIG. 3) of the adhesive 8 may be constant or may vary along the second direction D2. Further, the contour of the portion where the adhesive 8 is provided may be linear or wavy.

The packaging format of the absorbent article 1 in the individually packaged absorbent article 100 of this embodiment has been described above with reference to FIGS. A stop can also be formed. As described above, the anti-slip portion is a member for preventing slippage from the underwear when attached to the underwear, and is preferably made of an adhesive. The adhesive (adhesive for absorbent articles) forming the non-slip portion of the absorbent article can be made of the same material as the above-described adhesive 8 formed at the end of the packaging sheet 10 .

At the time of packaging, the adhesive for absorbent articles can be applied not to the absorbent article 1 but to the packaging sheet 10 when the absorbent article 1 is packed. For example, as shown in FIG. 3 , before the absorbent article 1 is placed, the pressure-sensitive adhesive for absorbent articles is applied to the area where the absorbent article 1 is to be placed in the peeling treatment section 21 of the inner surface IF of the packaging sheet 10 . 9, 9, . . . can be formed. Then, by placing the absorbent article 1, the non-skin side of the absorbent article 1 (the non-skin side of the back sheet) comes into contact with the adhesive for absorbent articles 9, 9, . . . (FIG. 5), The packaging sheet 10 and the absorbent article 1 are folded together while maintaining their contact state (FIGS. 1 and 2). Thereafter, when the absorbent article 1 is peeled off from the packaging sheet 10 at the start of use of the absorbent article 1, the absorbent article adhesives 9, 9, . It migrates to the skin side and is fixed.

Here, the absorbent article adhesives 9, 9, . . . preferably extend in the same direction as the adhesive 8, that is, extend along the second direction D2. As a result, when manufacturing the individually packaged absorbent article 100, the adhesive 8 used when the absorbent article is discarded and the absorbent article adhesives 9, 9, . . . are simultaneously applied using a slot coater or the like. be able to.

While the adhesive (disposal adhesive) 8 and the absorbent article adhesives 9, 9, ... are applied (Fig. 3), the adhesive 8 and the absorbent article adhesives 9, 9, ... are in contact with each other. preferably not. Further, the absorbent article pressure-sensitive adhesives 9, 9, . It is preferable that they are separated from each other by 8 mm or more.

In the example shown in FIGS. 3 and 4, the adhesive for absorbent articles 9, 9, . A separate release sheet can also be used. In that case, the release sheet may be a sheet whose inner surface is release-treated and whose outer surface is not release-treated. Then, the outer surface of the release sheet is non-peelably adhered to the inner surface IF of the packaging sheet 10, and the inner surface of the release sheet is arranged so as to face the absorbent article 1 on which it is placed. The release sheet may have a size and a shape that cover the intended application positions of the absorbent article pressure-sensitive adhesives 9, 9, . . . .

7 and 8 show modifications of the adhesive 8. FIG. Although the adhesive 8 shown in FIGS. 1 to 6 is formed continuously in the second direction D2, the adhesive 8 may be formed discontinuously as shown in FIG. In that case, the longest continuous portion may be formed in the center in the second direction D2, and one or more portions shorter than the central continuous portion may be formed on each side in the second direction D2. In the example shown in FIG. 7, when the ends of the packaging sheet are attached, at least the center of the second direction D2 can be attached, so the attachment of the packaging sheet can be ensured. can be reduced.

Moreover, multiple adhesives 8 may be formed along the second direction D2. By forming a plurality of adhesives, when the used absorbent article is wrapped with the packaging sheet 10, the packaging sheet 10 can be attached at a plurality of locations spaced apart in the first direction D1. function can be improved. The adhesive 8 may include an outer adhesive 8a and an inner adhesive 8b spaced apart from each other, as shown in FIG. In this case, the outer adhesive 8a may be formed longer and the inner adhesive 8b may be formed shorter, so that the adhesive 8 is doubled in the center of the second direction D2 and singled in the region near the end. good. As a result, the fastening effect at the center in the second direction D2 is enhanced, and by forming the single layer portion, the amount of the adhesive used can be reduced and the cost can be suppressed.

FIG. 9 shows a modified example of the folded portion Re. In the example shown in FIG. 9, the free end of the folded portion Re in the first direction D1 is not linear, and the projecting portion (convex Part) has p. The example shown in FIG. 9 differs from the packaging sheet 10 shown in FIG. 3 in that there is such a protrusion p, and other structures may be the same. The protrusion p may be of a size and shape that can be picked up by the user. In the example shown in FIG. 9, the shape of the protruding portion p is a trapezoid whose long side is inside the first direction D1. It may be circular, elliptical, or the like with a cutting line inside one direction D1.

When trying to obtain the individually packaged absorbent article 100 using the packaging sheet 10 including the folded portion Re having the protrusions p as shown in FIG. 9, the packaging sheet 10 shown in FIG. First, the projecting portion p is folded back along the fold line La to the outer surface. Thereafter, similarly to the example shown in FIGS. 3 and 4, the folded portion Re is folded toward the inner surface IF in the first direction D1 to face the inner surface IF of the facing portion Rf. As a result, the adhesive 8 applied to the folded portion Re is placed between the folded portion Re and the facing portion Rf. After that, the absorbent articles can be individually packaged in the same packaging style as the packaging style described with reference to FIGS. 1 to 6. FIG.

FIG. 10 shows an individually packaged absorbent article 100 including the packaging sheet 10 including the folded portion Re having the protrusion p shown in FIG. 9 and the absorbent article 1 individually packaged by the packaging sheet. As shown in FIG. 10, the protrusion p of the folded portion Re is exposed from the folding line Le, so that the user grasps and pulls the protrusion p when unpacking the individually packaged absorbent article 100 . be able to. This facilitates the operation of lifting the first region R1 from the second region R2 and releasing the bonding of the packaging sheets at the seal portions 18,18. In addition, in a configuration in which no fastening tape is provided, a user accustomed to products provided with a fastening tape may not immediately find a place to grip for opening. However, since the protruding portion p serves as a mark of the holding position for opening, the user can smoothly perform the opening operation.

Furthermore, since the projection p is provided, the projection p can be gripped when the used absorbent article is discarded and when the packaging sheet 10 is wrapped around the used absorbent article. That is, the end of the packaging sheet 10 can be gripped at a position away from the adhesive 8, and the possibility of the adhesive 8 sticking to the hand can be reduced. Further, since the projecting portion p is provided in the center of the second direction D2, the packaging sheet 10 can be tightly wound in the center of the second direction D2, and the operation of winding the packaging sheet 10 around the used absorbent article can be made easier. can be done with certainty.

In addition, the protrusion p can be made more rigid than other parts of the packaging sheet 10 so that the user can easily grip it. For example, the projections p may be embossed, coated with small pieces to increase rigidity, or coated with a composition such as a polymer that can increase rigidity.

FIG. 11 shows another modification of the folded portion Re. In the example shown in FIG. 11, after the folded portion Re is once folded back to the inner surface, the portion of the packaging sheet 10 that has been folded back into a double layer is further folded back. Different from the example shown. For example, from the state shown in FIG. 11A, the folded portion Re is folded back along the folding line Le in the first direction D1 toward the inner surface IF. In the illustrated example, the adhesive 8 is applied to the facing portion Rf that faces the folded portion Re when the folded portion Re is folded back, and after the folded portion Re is folded back, the adhesive 8 faces the folded portion Re. Rf (FIG. 11(b)).

Further, from the state shown in FIG. 11(b), the folded portion Re and the facing portion Rf that are overlapped are folded in the first direction D1 along the folding line Le′ along the second direction D2, that is, the folded portion is folded. A further fold is made in the same direction as the fold at line Le. The position of the folding line Le' is preferably at a position that is approximately half the length of the folded portion Re in the first direction D1. As a result, as shown in FIG. 11(c), a portion where four packaging sheets 10 are laminated is formed at the end portion in the first direction D1. Therefore, the rigidity of the outer end portion of the first region R1 in the first direction D1 is increased, making it easier for the user to grip.

In the example shown in FIG. 11, it is preferable that the adhesive 8 is applied so as not to overlap the folding line Le and the folding line Le'.

In the example described above, the folded portion Re is folded back toward the inner surface IF of the packaging sheet 10 . However, the folded portion Re may be folded back toward the outer surface OF. In that case, a facing portion Rf facing the folded portion Re is also formed on the outer surface OF, and the adhesive 8 disposed between the folded portion Re and the facing portion Rf is also applied to the outer surface OF. Then, in the same manner as described above, it is possible to configure such that one of the folded portion Re and the facing portion Rf is peeled and the other is not peeled. When disposing of the used absorbent article, the folded portion Re is unfolded to expose the adhesive 8, the packaging sheet 10 is wrapped around the used absorbent article, and then the adhesive 8 is used to form the end portion of the packaging sheet 10. can be attached to other areas of the packaging sheet 10. At that time, the area to be contacted by the adhesive 8 may be a non-peeling treated area.

Further, the folded portion Re does not necessarily have to be formed only on one end in the first direction D1, that is, on the side of the first region R1. The folded portion Re may be formed not on the first region R1 side but on the second region R2 side in the first direction D1, that is, on the end portion including the other end 12 . Alternatively, they may be formed at both ends in the first direction D1. When the folded portions Re are formed in the first region R1 and the second region R2, when the used absorbent article is discarded, both folded portions Re are unfolded to expose the adhesive 8, and one adhesive 8 is A used absorbent article is placed on a certain position to fix the used absorbent article, and after wrapping the packaging sheet 10 around the used absorbent article, the other part provided with the adhesive 8 is covered with the packaging sheet 10 , and the packaging sheet 10 can be fixed.

It is preferable that the individually packaged absorbent article 100 according to this embodiment does not include a fastening tape. There is a possibility that the opening may not be smooth due to the difference in Therefore, in this embodiment, it is preferable to have a configuration that makes it easier to open the individually packaged absorbent article 100 .

For example, the modified example shown in FIG. 12 has the same configuration as the example described with reference to FIGS. It differs from the example described with reference to FIGS. 1 to 6 in that 19, 19 are formed. The discontinuous seal portions 19, 19 are formed so as to straddle the folding line Le, and preferably have a length of 5 to 7 mm in the first direction D1. When the individually packaged absorbent article 100 is unsealed, a particularly large force is required in the initial operation of first lifting the first region R1 and peeling the first region R1 from the second region R2. On the other hand, in this example, the seal discontinuous portions 19, 19 are formed across the folded portion folding line Le, and the first region R1 is not joined to the second region R2 in that range. Since the initial operation of peeling the region R1 from the second region R2 is facilitated, the operation of peeling the first region R1 can be smoothly performed. The example shown in FIG. 12 is preferable as a form in which a light incontinence pad is packaged.

13 and 14 is a configuration in which the sealing before opening is ensured while the opening operation is made easier. FIG. 13 is a plan view of the packaging sheet 10 in a fully unfolded state before the absorbent article is placed thereon, and is a view of the packaging sheet 10 viewed from the inside, corresponding to FIG. It is a diagram. 14 is a plan view of individually packaged absorbent article 100 obtained after packaging absorbent article 1 using packaging sheet 10 shown in FIG. 13, and is a view corresponding to FIG.

In general, when the seal portions 18, 18 are formed on the peel-treated portions of the packaging sheet 10, the bonding strength of the seal portions tends to be weak. Therefore, as shown in FIG. 3, when the entire region other than the folded portion Re is the release treated portion 21, the bonding strength between the seal portions 18, 18 tends to be weak. Therefore, from the viewpoint of obtaining more reliable sealing, both edges of the packaging sheet 10 may be configured to be non-peeling treated portions 22 without being subjected to the peeling treatment. However, when both edges are made into the non-peeling treated portion 22, the bonding strength increases, so a larger force is required in the opening operation, especially in the opening operation, and depending on the user who is weak in force, the individual packaging absorbability may be poor. Opening the item 100 may be difficult. On the other hand, in the example shown in FIGS. 13 and 14 , the peeling-treated portions 21 are discontinuous at both edges of the packaging sheet 10 in the second direction D2, and partially become the non-peeling-treated portions 22. . When the absorbent article 1 is individually packaged by folding the absorbent article 1 in three rolls (FIG. 14), the peeling treated portions 21 on both edges are formed in a range including the folded portion Re and the facing portion Rf in plan view when viewed in the first direction D1. be done.

Since the third region R3, the second region R2, and the first region R1 are overlapped in the portion where the folded portion Re and the facing portion Rf are overlapped, a total of four packaging sheets are overlapped. . When the number of packaging sheets that are stacked in this manner is large, a greater pressure is applied in the sealing process of both edges, and the bonding strength of the seal portions 18 tends to become even stronger. Therefore, if the packaging sheet in the portion where the number of overlapping packaging sheets is large is subjected to peeling treatment, the bonding strength can be moderately weakened, and the weak bonding portions 18w, 18w can be formed in the sealing portions 18, 18. (Fig. 14). As a result, the opening operation, particularly the opening operation, can be performed smoothly, and the joint strength of the seal portions 18 can be ensured to improve the sealing performance of the individually packaged absorbent article 100 .

Furthermore, as shown in FIGS. 15 and 16, the individually packaged absorbent article 100 may have a configuration in which the areas of both edges of the overlapping portion of the folded portion Re and the facing portion Rf are reduced. FIG. 15 is a plan view of the packaging sheet 10 in a completely unfolded state before the absorbent article is placed thereon, and is a view of the packaging sheet 10 viewed from the inside, corresponding to FIG. is. 16 is a plan view of individually packaged absorbent article 100 obtained after packaging absorbent article 1 using packaging sheet 10 shown in FIG. 15, and is a view corresponding to FIG.

As shown in FIG. 15, the packaging sheet 10 has cutouts r, r near the folding line Le. In other words, the contour of the packaging sheet 10 is concave toward the center in the second direction D2 at the folding line Le. Since the contour of the folded portion Re and the contour of the facing portion Rf are symmetrical with respect to the folded portion folding line Le, in the individually packaged absorbent article 100, the folded portion Re and the facing portion Rf are symmetrical. The contours match (Fig. 16). As shown in FIG. 16, notches r and r are formed at both edges of the overlapped portion of the folded portion Re and the facing portion Rf. It's becoming Therefore, the force required for the opening operation can be reduced, and the opening operation can be performed more smoothly.
