Description

The present invention relates to packaging structures and packaged absorbent articles.

Sanitary napkins, panty liners, incontinence pads and the like are known as absorbent articles. After using such an absorbent article, when replacing it with a new one, the user needs to discard the used absorbent article. At that time, the user wraps the used article in the wrapping sheet of the new absorbent article to be used from now on, that is, the wrapping sheet left after the new absorbent article is opened and the contents (article) are taken out, and discarded. often do. Therefore, conventionally, various ideas have been devised for the structure of a packaging sheet that can be used even at the time of disposal.

For example, in Patent Document 1, the packaging film 14 is an individual package of an absorbent article having a bag-like portion 14a at least in part, and when the used napkin 21 is discarded, the used napkin 21 is wrapped in a bag. It is disclosed that it is used to be inserted into the shaped portion 14a and fastened with the mounting tape 13. As shown in FIG.

JP-A-2001-87306

However, in the configuration disclosed in Patent Literature 1, when disposing of the used article, it is necessary to push the used article through the opening of the bag-like portion. You may get your hands dirty with the body fluids you are carrying, which may not be hygienic.

In view of the above points, an object of one aspect of the present invention is to provide a packaging structure for absorbent articles that can be used to more easily and hygienically dispose of used absorbent articles.

A first aspect of the present invention is to provide a packaging sheet having a predetermined width for packaging an absorbent article, and an auxiliary sheet that is provided on the inner surface of the packaging sheet and is expandable beyond the edges in the width direction of the packaging sheet. A packaging structure for absorbent articles, comprising:

According to the first aspect, the packaging structure has a packaging structure in which the packaging sheet and the auxiliary sheet are combined, and the auxiliary sheet is expandable beyond the edges in the width direction. Therefore, the structure after taking out the contents (absorbent article) from the state in which the absorbent article is packaged can be a disposal sheet having an area exceeding the area of the packaging sheet. By using such a disposal sheet with an enlarged area, even relatively large used absorbent articles can be easily wrapped.

In addition, when the used absorbent article is rolled up in the longitudinal direction and discarded, body fluid tends to seep out from the width direction. On the other hand, since the packaging structure of this aspect can be a disposal sheet expanded in the width direction by the auxiliary sheet, even if the used absorbent article is wide, the width direction end can be covered with the auxiliary sheet. can be done. Therefore, the used absorbent article can be wrapped and discarded hygienically without soiling the hands.

In a second aspect of the present invention, the absorbent article includes a liquid-impermeable backsheet, an absorbent body, and a liquid-permeable topsheet laminated in this order, and a non-slip material is provided on the backsheet side. The auxiliary sheet is a release sheet having a release surface on which at least one side is releasable, and is arranged such that the release surface faces the anti-slip member in a state in which the absorbent article is packaged. .

According to the second aspect, the auxiliary sheet is a release sheet that faces the anti-slip material provided on the absorbent article. Therefore, the auxiliary sheet can function not only as a release sheet for the anti-slip material, but also as a disposal sheet that can easily and hygienically wrap used articles.

In a third aspect of the present invention, the absorbent article has wings, and the anti-slip member includes a wing anti-slip member provided on the backsheet side of the wing.

According to the third aspect, the auxiliary sheet can be a release sheet facing the wing anti-slip material. Therefore, even in a packaging structure in which an absorbent article with wings is packaged, the auxiliary sheet protects the anti-slip material for the wings as a release sheet, while easily wrapping a large used absorbent article. Sheets can be configured.

In a fourth aspect of the present invention, the auxiliary sheet is foldable at least in the width direction, and the release surface faces the anti-slip member in the folded state.

According to the fourth aspect, since the auxiliary sheet can be folded in the width direction, the auxiliary sheet can be can be compactly accommodated in the packaged absorbent article in a flat state. In addition, since the release surface faces the anti-slip material even in the folded state, the auxiliary sheet serves as a release sheet that covers and protects the anti-slip material in the wrapped state and can be easily peeled off from the anti-slip material at the start of use. can be fulfilled reliably.

In a fifth aspect of the present invention, in a state in which the absorbent article is wrapped, the packaging sheet is folded along at least two fold lines along the width direction, and has seal portions on both edges in the width direction. and the auxiliary sheet does not overlap the seal portion.

According to the fifth aspect, when the absorbent article is wrapped, the auxiliary sheet does not overlap the sealing portion of the packaging sheet, so good sealing performance of the packaging sheet can be ensured.

In the sixth aspect of the present invention, the auxiliary sheet has an adhesive portion on the widthwise end of the inner surface in the unfolded state.

According to the sixth aspect, when the used absorbent article is disposed of, when the auxiliary sheet is wrapped in the used article so as to be overlapped in the width direction, the auxiliary sheet can be used by the adhesive portion provided on the auxiliary sheet. Auxiliary sheets can be attached to finished articles or to each other. As a result, the used article can be wrapped in the width direction as well, and body fluid can be prevented from oozing out in the width direction during the disposal operation.

A seventh aspect of the present invention is a packaged absorbent article comprising the packaging structure according to any one of the first to sixth aspects and an absorbent article.

According to the seventh aspect, it is possible to provide a packaged absorbent article that exhibits the same effects as those obtained in any one of the first to sixth aspects.

According to one aspect of the present invention, it is possible to provide a packaging structure for absorbent articles that can be used to more easily and hygienically dispose of used absorbent articles.

<First embodiment>
FIG. 1A shows an unfolded packaging structure 50 for packaging absorbent articles according to a first embodiment of the present invention. As shown in FIG. 1A, the packaging structure 50 is attached to and detached from the packaging sheet 10 for packaging the absorbent article and the inner surface of the packaging sheet 10, that is, the surface on which the absorbent article to be packaged is placed, by means of the fixing portion 25. and an auxiliary seat 20 that is incapably fixed (fixed).

As shown in FIG. 1A, the packaging sheet 10 may have a rectangular elongated shape. In the drawings of this specification, the longitudinal direction of the unfolded packaging sheet 10 is defined as a first direction D1, and the width direction orthogonal to the longitudinal direction D1 is defined as a first direction D2. The thickness direction of the packaging sheet 10 (and the packaging structure 50), which is perpendicular to both the longitudinal direction D1 and the width direction D2 of the unfolded packaging sheet 10, is defined as a third direction D3 (shown later).

The size and shape of the packaging sheet 10 are not particularly limited as long as the absorbent article can be wrapped without being exposed. As for the dimensions of the packaging sheet 10, depending on the size and shape of the absorbent article to be packaged, the length in the first direction D1 (sometimes simply referred to as length) can be 100 to 450 mm, and the length in the second direction D2 can be 100 to 450 mm. The length (sometimes simply referred to as width) can be from 70 to 250 mm.

The auxiliary sheet 20 extends beyond the edge in the second direction (the width direction of the packaging sheet 10) D2 in the unfolded state (unfolded state). In the example of FIG. 1A, the auxiliary sheet 20 extends beyond both edges of the packaging sheet 10 in the second direction D2 in the second direction D2. The auxiliary seat 20 in this embodiment can be folded in the second direction D2.

The material of the packaging sheet 10 is not particularly limited, and a resin film, nonwoven fabric, paper, or the like can be used. A single-layer sheet made of a predetermined material may be used, or a laminated sheet formed by laminating a plurality of layers made of different materials may be used.

On the other hand, the material of the auxiliary sheet 20 is also not particularly limited, and a resin film, nonwoven fabric, paper, or the like can be used. The auxiliary sheet 20 may also be either a single layer sheet or a laminated sheet. Further, the auxiliary sheet 20 may be made of the same material as the packaging sheet 10, or may be made of a different material. However, the auxiliary sheet 20 can also be a sheet having another role in the packaging structure 50, such as a release sheet for protecting the anti-slipping material, as will be described later.

Note that the packaging sheet 10 and the auxiliary sheet 20 can also be made of the same material. In that case, one sheet material can be cut to form the packaging structure 50 in which the packaging sheet 10 and the auxiliary sheet 20 are connected. In this case, the fixing portion 25 becomes unnecessary.

Since the original function of the packaging structure 50 is to package absorbent articles, the packaging of absorbent articles by the packaging structure 50 of this embodiment will be described first.

When wrapping an absorbent article with the packaging structure 50 according to this embodiment, a structure in which the packaging sheet 10 and the auxiliary sheet 20 are combined is prepared in an unfolded state as shown in FIG. 1A. Then, the auxiliary sheet 20 is folded before placing the absorbent article. Specifically, both end regions 21, 21 of the auxiliary sheet 20 are valley-folded along folding lines L1, L1 along the first direction D1, respectively. That is, the both end regions 21, 21 are folded toward the inner surface side of the packaging sheet 10, inward in the second direction D2, and overlapped with 23 between the end regions 21, 21. As shown in FIG. Either of the end regions 21, 21 may be folded first.

The folding lines L1, L1 are positioned inside both edges of the packaging sheet 10 in the second direction D2. Therefore, after the auxiliary sheet 20 is folded, the length of the auxiliary sheet 20 in the second direction D2 in plan view corresponds to the length of the central region 23 in the second direction D2, and the length of the packaging sheet 10 in the second direction D2. (the width of the packaging sheet 10). Further, the auxiliary sheet 20 does not protrude from the packaging sheet 10 in the second direction D2 in plan view. It is preferable that each of the folding lines L1, L1 is positioned inside the second direction D2 by 5 to 25 mm from each edge of the packaging sheet 10 in the second direction D2.

The length of the auxiliary sheet 20 after being folded in the second direction D2 (corresponding to the length of the central region 23 in the illustrated embodiment) may be 50 to 240 mm, preferably 50 to 110 mm. Also, the length of the auxiliary sheet 20 in the first direction D1 may be 40 to 150 mm.

After folding the auxiliary sheet 20 along the folding lines L1, L1, the absorbent article 1 is placed on the inner surface side of the packaging structure 50 (the front side of the paper surface of FIG. 1A). FIG. 1B shows the state after the absorbent article 1 is placed. FIG. 1B shows a partially broken sanitary napkin as an example of the absorbent article 1 . As shown in FIG. 1B, the absorbent article 1 packaged by the packaging structure 50 according to this embodiment includes a liquid-impermeable backsheet 2, a liquid-permeable topsheet 3, and an absorbent sheet provided between the two sheets. It comprises a main body 8 at least composed of the body 4 .

After placing the absorbent article 1, the packaging sheet 10 (and the packaging structure 50) is folded together with the absorbent article 1 along the folding line along the second direction D2. More specifically, as shown by the arrow in FIG. 1B, the first region 11 including one end 15 of the packaging sheet 10 in the first direction D1 is valley-folded along the folding line X1, that is, the inner surface of the packaging sheet 10 is folded. turn around. Subsequently, the second region 12 including the other end 16 opposite to the one end 15 is valley-folded along the folding line X2, that is, folded back toward the inner surface of the packaging sheet 10 .

FIG. 1C shows the state after the absorbent article 1 is wrapped by the packaging structure 50, that is, the wrapped absorbent article (wrapped absorbent article) 100. FIG. In the packaged absorbent article 100, the first region 11 and the second region 12 of the packaging sheet 10 are detachably attached with a tab tape 19 extending from the center of the other end 16 in the second direction D2. The tab tape 19 has a portion (tab) that can be gripped with fingers at the tip of the side extending from the other end 16 of the packaging sheet 10, and the user holds the grippable portion and pulls the tab tape 19. , the packaged absorbent article 100 can be unsealed. In addition, this tab tape 19 can be arranged after folding along the folding lines X1 and X2. ).

In addition, as shown in FIG. 1C, unsealable seal portions 40, 40 may be formed on both edges of the packaged absorbent article 100 in the second direction D2. Such sealed portions 40, 40 can be formed by sealing the layers of the stacked packaging sheets 10 by heat sealing, ultrasonic sealing, or the like. Moreover, it can be formed by intermittently providing a large number of adhesive layers with a small area between the layers of the stacked packaging sheets 10 so as to be unsealable. For example, the seal portions 40, 40 are provided with a width of 3 to 20 mm (length in the second direction D2) in a range from the edge in the second direction D2 to a position of 3 to 20 mm along the second direction D2. can be done.

FIG. 1D shows a cross-sectional view taken along line II of FIG. 1C. The packaged absorbent article 100 has a structure in which a plurality of layers are stacked in the third direction (thickness direction) D3. In FIG. 1D, the third region 13, which is the region between the first region 11 and the second region 12, is arranged at the bottom, and the second region 12 is arranged at the top. As shown in FIG. 1D, the absorbent article 1 does not exist in the seal portions 40, 40 formed on both edges of the packaging sheet 10 in the second direction D2. Moreover, in order to improve the sealing property between the layers of the packaging sheet 10, it is preferable that the auxiliary sheet 20 does not exist in the sealing portions 40,40.

To open the packaged absorbent article 100 shown in FIGS. 1C and 1D, the grippable portion of the tab tape 19 is pulled to separate the tab tape 19 from the second region 12, and the packaging sheet is peeled off while peeling off the seals of the seal portions 40, 40. The second region 12 of 10 is opened outward in the first direction D1. Holding the exposed end of the absorbent article 1 and the second region 12 (the other end 16) of the packaging sheet 10 with both hands and pulling them in opposite directions, the absorbent article 1 is peeled off from the packaging sheet 10. can be removed.

After the absorbent article 1 is removed, the packaging structure 50 is left in which the packaging sheet 10 and the auxiliary sheet 20 are non-detachably fixed. Here, by reopening the folded auxiliary sheet 20, the unfolded packaging structure 50 as shown in FIG. 1A can be obtained. The operation of unfolding the auxiliary sheet 20 is to open the end regions 21, 21 folded back along the folding lines L1, L1 (FIG. 1A) outward in the second direction D2 by performing the operation opposite to the folding. In addition, when the absorbent article 1 and the area of the auxiliary sheet 20 facing the absorbent article 1 are weakly fixed detachably, when the absorbent article 1 is removed from the packaging structure 50, the auxiliary Since the facing area of the sheet 20 is lifted by being pulled by the absorbent article 1, the expansion of the auxiliary sheet 20 is assisted.

In this embodiment, the packaged absorbent article 100 is formed by folding the packaging sheet 10 in three. It can also be folded in four or more. In that case, the length of the first region 11 in the first direction D1 is increased, and the first region 11 is extended inward in the first direction D1 by an additional fold line located outside the fold line X1 in the first direction D1. , the packaging sheet 10 can be folded together with the absorbent article 1 along the folding lines X1 and X2 as described above.

Next, the operation of discarding used absorbent articles using the packaging structure 50 according to this embodiment will be described. As mentioned above, when a user replaces an absorbent article with a new one, it is necessary to dispose of the used absorbent article. At that time, the used absorbent article is often rolled up or folded, wrapped in a wrapping sheet left after a new absorbent article is opened and taken out, and discarded.

Here, referring to FIG. 2, an operation (wrapping operation) of wrapping the used absorbent article 1a using the packaging structure 50 shown in FIG. 1A in order to discard the used absorbent article 1a will be described. As shown in FIG. 2(a), the used absorbent article 1a is often rolled in the longitudinal direction into a shape close to a cylinder. At that time, since an adhesive portion for preventing slippage is often provided on the back sheet side of the absorbent article, the used absorbent article 1a is arranged so that the liquid-impermeable back sheet side faces outside ( It is often rolled up so that the side with bodily fluids is on the inside) and the sticky part is exposed.

The used absorbent article 1a that has been rolled up is placed in the position of the packaging structure 50 where the auxiliary sheet 20 is arranged, in the width direction of the used absorbent article 1a and in the width direction of the packaging sheet 10 (second direction D2). Place it so that the Next, the portions of the auxiliary sheet 20 that protrude beyond the edges of the packaging sheet 10 in the second direction D2 (end regions 21, 21 described above) are moved toward the center of the packaging sheet 10 in the second direction D2, It is folded so as to cover the used absorbent article 1a (arrow in FIG. 2(a)).

As described above, the used absorbent article 1a is often rolled up so that the anti-slip adhesive portion disposed on the backsheet is exposed. Therefore, in such a case, the end regions 21, 21 of the auxiliary sheet 20 can be adhered and fixed to the adhesive portion of the used absorbent article 1a. By the operation up to this point, the widthwise end portions of the used absorbent article 1a can be covered as shown in FIG. 2(b).

After that, the used absorbent article 1a is rolled on the packaging sheet 10 in the longitudinal direction D1 from one end 15 side of the packaging sheet 10 to the other end 16 side where the tab tape 19 is provided. The packaging sheet 10 is wound around 1a (arrow in FIG. 2(b)). After being rolled up, it can be fixed with a tab tape 19 (FIG. 2(c)).

When the used absorbent article 1a contains a large amount of bodily fluids, the bodily fluids tend to seep out from the ends in the width direction, especially in a rolled or folded state. On the other hand, by using the packaging structure 50 according to the present embodiment when wrapping the used absorbent article 1a, it is possible to cover the width direction end of the used absorbent article 1a with the auxiliary sheet 20. It is possible to reduce the possibility of body fluid coming into contact with hands during the disposal operation such as moving the wrapped used absorbent article 1a to the trash can during or after the wrapping operation. In particular, according to the procedure of the above-described wrapping motion, the widthwise end portions of the used absorbent article 1a can be covered with the auxiliary sheet 20 at the beginning of the wrapping motion, so body fluids can be absorbed through the wrapping motion. can reduce the possibility of contact with hands.

Furthermore, in recent years, various types of absorbent articles have been manufactured and sold, some of which have large sizes for nighttime use. For example, absorbents with a partially thickened absorbent, those with three-dimensional gathers, those with a wide flap-shaped part in the area facing the buttocks when worn, etc., and those with a large volume as a whole. be. Therefore, when a large-sized absorbent article is to be replaced with a small-sized absorbent article, for example, when a nighttime sanitary napkin is to be replaced with a daytime sanitary napkin, the small-sized absorbent article must be packed. In some cases, a large-sized used absorbent article cannot be entirely wrapped with a wrapping sheet having a large size. More specifically, since the packaging sheet is often formed in an elongated shape, even if the packaging sheet can be wrapped around the used absorbent article, the width direction end of the used absorbent article is not wrapped. Since it protrudes from the sheet or the area of the other end in the width direction is widened, the user should apply the used absorbent article (specifically, the body fluid attached to the used absorbent article) Easy to touch from the edge.

It is conceivable to increase the width of the packaging sheet in order to wrap a large-sized used absorbent article, but this makes it difficult to hold the wrapped absorbent article and increases the cost. In addition, packaging sheets configured in the shape of a bag with gussets are also known (Patent Document 1, etc.). The sealability of the part tends to be weak.

On the other hand, according to the packaging structure 50 of the present embodiment, the auxiliary sheet 20 has a simple configuration that can be accommodated in the packaged absorbent article, so that the size and shape of the packaging sheet need not be changed. Moreover, the entire used absorbent article 1a can be simply and hygienically wrapped without lowering the sealing performance of the packaging sheet. That is, the packaging structure 50 of this embodiment can have both the original function of packaging absorbent articles and the excellent function of a disposal sheet.

Note that in the packaging structure 50 described with reference to FIGS. 1A to 1D and 2, the auxiliary sheet 20 is expandable beyond both edges of the packaging sheet 10 in the second direction D2. The sheet 20 may be configured to be expandable beyond one edge of the packaging sheet 10 in the second direction D2. For example, one end region 21 may be omitted from the auxiliary sheet 20 in FIG. 1A. Moreover, unlike the illustrated embodiment in which the lengths in the second direction D2 of the end regions 21, 21 are substantially equal, the lengths in the second direction D2 of both regions may be different.

In addition, in the illustrated packaging structure 50, the end regions 21, 21 of the auxiliary sheet 20 are configured to overlap, but the lengths of the end regions 21, 21 in the second direction D2 are adjusted to be short, You may configure so that they do not overlap. Also, the length of the end regions 21, 21 in the second direction D2 may be longer than that shown, for example, the length of the central region 23 between the end regions 21, 21 in the second direction D2. In that case, it can be folded along one or more additional fold lines such as valley folds or mountain folds along the first direction D1 in addition to the illustrated fold lines L1, L1. In this case as well, it is preferable that the auxiliary sheet 20 does not overlap the seal portions (40, 40 in FIG. 1D) in a plan view when the absorbent article is wrapped to form a wrapped absorbent article.

Furthermore, in the illustrated embodiment, the shape of the auxiliary sheet 20 is a rectangle having long sides in the second direction D2 in plan view, but the shape is not limited to a rectangle. As long as the function of the packaging structure 50 to wrap the absorbent article 1 is not hindered, for example, the length of the auxiliary sheet 20 in the first direction D1 varies depending on the location, and the second direction D2 extends outward in the first direction. The D1 length may be increased, or the contour of the auxiliary sheet 20 may be uneven.

In the packaging structure 50, the fixing portion 25 that non-detachably fixes the packaging sheet 10 and the auxiliary sheet 20 is provided in an elongated shape in plan view along the second direction D2. The area and plan view shape of the fixing portion 25 are not limited to those shown in the drawings as long as they can be fixed to the seat 10 in a non-detachable manner. Further, although the fixing portion 25 is arranged in the center of the central region 23 of the auxiliary sheet 20 in the first direction D1 and the center in the second direction D2, the position of providing the fixing portion 25 is arbitrary in the first embodiment. . Therefore, for example, the entire surface of the central region 23 of the auxiliary sheet 20 can be the fixed portion 25, or a plurality of fixed portions 25 can be intermittently provided, for example, a plurality of dot-shaped fixed portions.

The fixation by the fixation part 25 is not particularly limited as long as it is formed so as not to be detachable, and for example, it can be formed by an adhesive. Further, the fixed portion 25 may be formed by sealing the packaging sheet 10 and the auxiliary sheet 20 by means of sealing means such as heat sealing or ultrasonic sealing, sewing, or the like. In the present specification, non-detachable means that the packaging structure 50 is not detached when the user handles the packaging structure 50 in a normal operation.

In the first embodiment, the auxiliary sheet 20 may be divided into a plurality of pieces instead of one. For example, the central region 23 of the auxiliary sheet 20 in FIG. 1A can be omitted and the auxiliary sheet 20 can be configured with two portions corresponding to the end regions 21,21. In that case, it is preferable that the portions corresponding to the end regions 21, 21 are non-removably fixed to the packaging sheet 10 at the end portions inside the second direction D2.

<Second embodiment>
FIG. 3A shows an unfolded packaging structure 250 for packaging absorbent articles according to a second embodiment of the present invention. A packaging structure 250 according to this embodiment includes a packaging sheet 210 and an auxiliary sheet non-removably fixed to the inner surface of the packaging sheet 210 by a fixing portion 225, like the packaging structure 50 (FIG. 1A) according to the first embodiment. 220. The configuration of the packaging sheet 210 is the same as that of the packaging sheet 10 (FIG. 1A) in the packaging structure 50, but the configuration of the auxiliary sheet 220 is different in this embodiment. That is, the auxiliary sheet 220 has a shorter length in the second direction D2 than the auxiliary sheet 20 (FIG. 1A).

In this embodiment, the auxiliary sheet 220 is configured as a release sheet having a release surface. In this embodiment, the surface on the side facing the packaging sheet 210 is a non-releasable surface that does not have releasability, while the surface on the opposite side (the front side of the paper surface) has releasability (releasability). is the peeling surface 220a. As will be described later, the release surface 220a is arranged so as to cover the adhesive portion for preventing slippage of the absorbent article.

Any release sheet may be used as long as it protects the adhesive portion with its release surface and can be easily peeled off from the adhesive portion to expose the adhesive portion when the absorbent article is used. The release sheet can be formed by subjecting the substrate to release processing. In that case, the material described for the auxiliary sheet 20 in the description of the first embodiment can be used as the base material. Then, the release processing can be performed by coating or spraying a release treatment liquid (release treatment liquid) such as a silicone resin, a fluorine resin, or a tetrafluoroethylene resin. Alternatively, a release sheet may be formed by forming a film using a resin that is used in the release treatment liquid having release properties.

The release sheet may have a release surface on only one side, or may have a release surface on both sides. However, as in this embodiment, one side of the release sheet has a release surface and the other side has a non-release surface, and the auxiliary sheet 220 is arranged so that the non-release surface faces the packaging sheet 210. In particular, when the fixing portion 225 is made of an adhesive, the adhesiveness between the auxiliary sheet 220 and the packaging sheet 210 can be improved, which is preferable. Also, the peeling process may be applied to a part of the surface of the auxiliary sheet (release sheet) 220 . In that case, for example, when the auxiliary sheet 220 and the absorbent article 201 are superimposed, it can be applied to at least the portion corresponding to the anti-slip adhesive portion of the absorbent article 201 .

As shown in FIG. 3A, in this embodiment, the auxiliary sheet 220 is valley-folded along the folding lines L1 and L1, and then folded along the folding lines L2 and L2 located inside the folding lines L1 and L1 in the second direction D2. Valley folding is possible. By folding along the folding lines L2, L2, the end regions 221, 221 are folded back toward the inner surface side of the packaging sheet 210, respectively. A central region 223 is formed between the end regions 221 , 221 .

In this embodiment, an absorbent article having wings is used as the absorbent article to be packaged. When the wing is attached to the underwear, it is folded back to the underwear side and adhered so that the absorbent article can be fixed to the underwear, thereby preventing the absorbent article from slipping or twisting. A wing is, for example, a flap-like portion extending from the main body at the longitudinal central portion of the absorbent article.

Hereinafter, packaging of the absorbent article 201 by the packaging structure 250 according to the second embodiment will be described. FIG. 3B shows an absorbent article 201 with a pair of wings W, W placed in a packaging structure 250. FIG. The absorbent article 201 has a configuration in which a backsheet 203, an absorbent body 204, and a topsheet 202 are laminated in this order, like the absorbent article 1 (FIG. 1A) of the first embodiment. The absorbent article 201 is arranged so that the front side of the paper surface of the drawing faces the top sheet 203 side, that is, the back sheet 202 side of the absorbent article 201 faces the packaging sheet 210 . In FIG. 3B, the pair of wings W, W of the absorbent article 201 are folded inwardly in the second direction D2 toward the topsheet side (the front side of the paper surface of the drawing). A pair of wings W, W before being folded is indicated by a dashed line.

A pair of wings W, W are provided with adhesive portions 209, 209 on the back sheet 202 side, respectively, for fixing each wing to the underwear. In the arrangement shown in FIG. 3B, the adhesive portions 209, 209 are exposed when the pair of wings W, W are folded back.

As shown in FIG. 3B, the absorbent article 201 is not placed on the auxiliary sheet 220, but placed between the packaging sheet 210 and the auxiliary sheet 220. As shown in FIG. In such an arrangement, for example, the packaging sheet 210 and the auxiliary sheet 220 are non-removably fixed by the fixing part 225, and the parts other than the fixing part 225 are non-fixed parts to form the packaging structure 50 (FIG. 3A). . Then, the absorbent article 201 can be obtained by placing the absorbent article 201 on the non-fixed portion between the packaging sheet 210 and the auxiliary sheet 220 .

After that, the auxiliary sheet 220 is valley-folded inward in the second direction along the folding lines L1, L1 shown in FIG. 3B, and further valley-folded inward in the second direction along the folding lines L2, L2. The planar view shape of the auxiliary sheet 220 folded in this way is equal to the shape of the central region 223 of the auxiliary sheet 220 . Thereafter, the packaging sheet 210 (and the packaging structure 250) are folded together with the absorbent article 201 along the folding line along the second direction D2 so that the absorbent article 201 faces inside. That is, the first region 211 of the packaging sheet 210 is valley-folded along the folding line X1 shown in FIG. 3B, and then the second region 212 is valley-folded along the folding line X2.

In this embodiment, each end of the auxiliary sheet 220 in the second direction D2 is folded back by valley folding. Although the non-peeling surface of the auxiliary sheet 220 is exposed when folded back by the valley fold, as shown in FIG. The length of the folded portion in the second direction D2 is short because the folded portion is folded. Therefore, a large portion of the release surface 220a in the central region 223 of the auxiliary sheet 220, particularly a large portion of the release surface 220a in the central portion in the second direction D2 can be exposed. Therefore, when the packaging sheet 210 is tri-folded in the first direction D1 together with the absorbent article 201, specifically, when the first region 211 is valley-folded along the folding line X1, the release surface of the auxiliary sheet (release sheet) 220 220a can be made to face the exposed adhesive portions 209, 209. FIG. Thereby, the auxiliary sheet 220 can be detachably joined to the adhesive portions 209 and 209 and protected.

Alternatively, before the first region 211 is valley-folded along the folding line X1, instead of providing the adhesive portions 209 on the back sheet 202 side of the wings W, W, the auxiliary sheet (release sheet) 220 is removed. An adhesive may be placed on the peeling surface 220a at the portion corresponding to the portion where the adhesive portion is to be formed on the back sheet 202 of the wings W and W. As shown in FIG. Accordingly, by valley-folding the first region 211 along the folding line X1, the adhesive disposed on the auxiliary sheet 220 can be transferred to the absorbent article 201 side.

After folding in the first direction D1 along the folding lines X1 and X2, the tab tape 219 is used for fixing, similarly to the first embodiment, and seal portions are similarly formed on both edges in the second direction D2 for sealing. . As a result, it is possible to obtain the packaged absorbent article 200 having the same appearance as the packaged absorbent article 100 shown in FIG. 1C described in the first embodiment. Although a plan view of the packaged absorbent article 200 is omitted, FIG. 3C shows a cross-sectional view of the packaged absorbent article 200 cut along the second direction D2. FIG. 3C can be said to correspond to FIG. 1D. As shown in FIG. 3C, the release surface 220a of the auxiliary sheet (release sheet) 220 adheres to the adhesive portions 209, 209 of the absorbent article 201, protects the adhesive portions 209, 209, and protects the absorbent article. It is possible to prevent the adhesive portions 209 and 209 from sticking to another component in 200 . Note that FIG. 3C also shows seal portions 240, 240 formed on both edges in the second direction D2 of the packaging sheet 210 of the packaged absorbent article 200. As shown in FIG.

Thus, in the present embodiment, the auxiliary sheet 220 having one surface as the release surface 220a and the other surface as the non-release surface is used, and the auxiliary sheet 220 is continuously valley-folded along the folding lines L1 and L2. do. Therefore, the end regions 221, 221 of the auxiliary sheet 220 do not overlap each other. In addition, as shown in the figure, since the release surface 220a is folded so as to expose a large area of the central region 223, the adhesive wing portions 209, 209 of the absorbent article 201 can be protected, and the fixing portion 225 in particular uses an adhesive. In this case, the adhesiveness between the packaging sheet 210 and the auxiliary sheet 220 can be ensured.

Furthermore, another example of packaging the absorbent article 201 with the packaging structure 250 according to the second embodiment will be described with reference to FIG. 3D. First, similarly to the example shown in FIG. 3B, the absorbent article 201 is placed on the inner surface of the packaging sheet 210, and the pair of wings W are folded back in the second direction D2. After that, as shown in FIG. 3D, an auxiliary sheet (release sheet) 220 is placed so that the release surface 220a is in contact with the wings W and the adhesive portions 209, 209 of the W. As shown in FIG. Specifically, the auxiliary sheet 220 is placed in a state in which both ends in the second direction D2 are folded twice toward the side facing the absorbent article 201 inward in the second direction D2.

Further, as shown in FIG. 3D, the packaging sheet 210 is folded in three along the folding lines along the second direction D2 with the absorbent article 201 facing inside. Specifically, the first region 211 is folded back along the folding line X1 by valley folding, and the second region 212 is folded back along the folding line X2 by valley folding. In order to fix the first region 211 and the auxiliary sheet 220 , a fixed adhesive layer or the like is formed at a predetermined position of the first region 211 and/or the auxiliary sheet 220 before folding the first region 211 . A portion 225 may be provided.

Even with such packaging, the packaged absorbent article 200 according to the second embodiment can be obtained. In the packaging form according to this example as well, the packaged absorbent article 200 is configured to have a cross section as shown in FIG. 3C.

To open the packaged absorbent article 200 shown in FIG. 3C, the grippable portion of the tab tape 19 is pulled to separate the tab tape 219 from the second region 12, and the seal portion 40, The second region 12 of the packaging sheet 10 is opened outward in the first direction D1 while peeling off the seal 40. - 特許庁Then, the exposed end of the absorbent article 201 and the second region 212 of the packaging sheet 210 are held with both hands and pulled in opposite directions to remove the absorbent article 201 from the packaging sheet 10. - 特許庁

After the absorbent article 201 is removed, the packaging structure 250 is left with the packaging sheet 210 and the auxiliary sheet 220 fixed together. Here, by reopening the folded auxiliary sheet 220, the unfolded packaging structure 50 as shown in FIG. 3A can be obtained. The operation of unfolding the auxiliary sheet 20 is to open the end regions 21, 21 folded back at the folding lines L1, L2 (FIG. 3A), respectively, outward in the second direction D2 by performing the operation opposite to the folding. .

FIG. 4 shows a modification of the second embodiment. 4(a) to (c) show cross-sectional views of the packaged absorbent article 200 cut along the second direction D2. These cross-sectional views are cross-sectional views corresponding to FIGS. 1D and 3C. The examples shown in FIGS. 4(a)-(c) all differ from the forms described with reference to FIGS. 3A-3D in that the auxiliary sheet 220 is folded back in a different form. In each example, a release sheet having a release surface 220a on one side is used as the auxiliary sheet 220, and the release surface 220a is detachably attached to the adhesive portions provided on the wings W, W.

In the example shown in FIG. 4A, the auxiliary sheet 220 is folded twice. More specifically, after being folded back inward in the second direction D2 along the fold line along the first direction D1 toward the peeling surface 220a, it is further folded outward in the second direction D2 along the fold line outward in the second direction D2. folded back. In this example, the first folding direction and the second folding direction are different, that is, the auxiliary sheet 220 is folded inward in the second direction D2 and then folded outward in the second direction. Therefore, the peeling surface 220 a can be opposed to the adhesive portions 209 , 209 . Further, the auxiliary sheet 220 shown in FIG. 4A has substantially the same length in the second direction D2 as the auxiliary sheet 20 shown in FIG. 1D.

Also in the example shown in FIG. 4B, the auxiliary sheet 220 is folded twice. However, in this example, the auxiliary seat 220 is configured to be expandable only in one side in the second direction D2. Specifically, one end region 221 (FIG. 3B, etc.) of the auxiliary sheet 220 is omitted. In this example, the first folding direction and the second folding direction of the auxiliary sheet 220 are different, that is, the auxiliary sheet 220 is folded inward in the second direction D2 and then folded outward in the second direction. is Therefore, the release surface 220a can be opposed to the adhesive portions 209, 209 as shown. Also, the length of the auxiliary sheet 220 in this example is substantially the same as the length of the auxiliary sheet 20 shown in FIG. It can be said that it has become 250.

In the example shown in FIG. 4(c), the auxiliary sheet 220 is folded back to face the packaging sheet 210 when viewed in the unfolded state (FIG. 3B). That is, it is folded in the direction opposite to the folding direction indicated by folding lines L1 and L2 in FIG. 3B. According to this folding method, the release surface 220a is not covered with the non-release surface, so when the absorbent article 201 is wrapped, the release surface 220a of the auxiliary sheet 220 does not cover the adhesive portions 209, 209. can. In the case of this example, the shape and/or size of the fixing portion 225 is changed or the shape and/or size of the folded portion of the auxiliary sheet 220 is changed so that the fixing portion 225 does not hinder the folding back to the packaging sheet 210 side.
