Description

Container for absorbent articles

The present invention relates to a container for absorbent articles.

Conventionally, there has been known a container for absorbent articles in which a plurality of absorbent articles such as diapers and sanitary napkins are accommodated inside a container member. As a container for such absorbent articles, in recent years, attention has been paid to paper package products using paper from the viewpoint of environmental consideration such as elimination of plastics. For example, Patent Literature 1 discloses a technology related to a packaged product in which a plurality of articles are housed inside a parallelepiped-shaped flexible gusset package formed by a laminate in which a paper layer and a film layer are laminated. ing.

Japanese Patent Application Publication No. 2019-59552

Since such a paper package is harder than a conventional package made of plastic film or the like, the shape of the containing member (for example, a parallelepiped shape) can be stabilized by providing folding guide lines to make it easier to fold the paper. It is common practice to let Further, in order to facilitate the formation of an opening for taking out the contained products, the surface of the paper package may be provided with cutting guide lines such as so-called perforations.

However, if the perforations, etc., are provided so as to overlap with the folding guide lines, the perforations spread before the opening and part of the opening opens, allowing moisture in the atmosphere to enter the interior. As a result, the moisture resistance may be impaired. In particular, a container for absorbent articles such as napkins and diapers needs to have high moisture resistance in order not to deteriorate the water absorption performance.

The surface is bent so as to form a predetermined angle with respect to the first surface with respect to the folding guide line, and the opening is formed from the first surface to the second surface. A receptacle for absorptive articles having a tear-off guide line, the tear-off guide line comprising a plurality of spaced cuts, each of the plurality of cuts being aligned with the fold guide line. A container for absorbent articles, characterized in that it is provided at a position that does not overlap with.

According to such a container for absorbent articles, the force generated when the first surface and the second surface are folded with reference to the folding guide line is less likely to act directly on the cutting guide line. Therefore, it is possible to prevent the notch from widening and opening a part of the opening before the container is opened. As a result, it is possible to realize an absorbent article container made of a paper package that has high moisture resistance, is easy to maintain its shape, and is easy to take out the absorbent article.

Such a container for absorbent articles has a vertical direction, a horizontal direction, and a front-back direction that intersect each other, and the folding guide line has a discontinuous portion that is partially discontinuous in the horizontal direction. Preferably, the plurality of cuts are provided at positions overlapping with the discontinuous portion.

According to such a container for absorbent articles, since the first surface and the second surface are loosely folded at the discontinuous portion, the notch constituting the cutting guide line is folded. force becomes difficult to act. Therefore, it is possible to easily suppress the opening of a part of the opening due to the widening of the cut. Thereby, the moisture resistance of the container can be further improved.

Such a container for absorbent articles has a vertical direction, a horizontal direction, and a front-back direction that intersect each other, and the folding guide line is continuously provided from one end side to the other end side in the horizontal direction. Preferably, the folding guide line is provided between two adjacent cuts in the vertical direction.

According to such a container for absorbent articles, it is difficult for the force due to bending to act directly on the cuts forming the tear-off guide line, and before the container is unsealed, the cuts widen to form a part of the opening. It is possible to suppress the opening of the part. In addition, since the folding guide line is continuous, it is easy to form a crease at the boundary between the first surface and the second surface, and the shape of the housing member can be more easily stabilized.

In such a container for absorbent articles, it is desirable that the width of the folding guide line is smaller than the interval between the two adjacent cuts.

According to such a container for absorbent articles, by making the interval between two adjacent cuts wider than the width of the folding guide line, the cuts constituting the cut guide line are prevented from being connected to each other. It becomes easy to suppress opening of the opening before opening. Thereby, the moisture resistance of the container can be further improved.

In such a container for absorbent articles, it is desirable that the width of the folding guide line is equal to or greater than the interval between the two adjacent cuts.

According to such a container for absorbent articles, it is possible to easily tear the containing member along the tear guide line by making the interval between the cuts forming the tear guide line as narrow as possible. Therefore, it is possible to facilitate the operation of forming the opening in the storage member that is hardened by containing the paper.

In such a container for absorbent articles, it is desirable that the smaller angle between the first surface and the second surface is greater than 90 degrees.

According to such a container for absorbent articles, the bending angle of the second surface with respect to the first surface is small, so that the force acting on the cutting guide line during bending can be weakened. This makes it easier to prevent the opening from being opened before it is unsealed, and it is possible to further improve the moisture resistance of the container.

Such a container for absorbent articles has a vertical direction, a horizontal direction, and a front-rear direction that intersect with each other, and the cutting guide line is located at a position straddling the boundary between the first surface and the second surface. Further, it is preferable that a pair of the cutting guide lines are arranged with a space therebetween in the left-right direction, and that the folding guide line is provided in a region between the pair of cut-off guide lines in the left-right direction.

According to such a container for absorbent articles, the portion of the containing member that is cut along the cutting guide line when forming the opening can easily maintain a bent state with respect to the folding guide line. , even after being cut off, it can be used as it is as a cover for covering the opening. As a result, it is possible to prevent water droplets or the like from entering from the opening.

The absorbent article storage body has a vertical direction, a horizontal direction, and a front-rear direction that intersect each other, and the storage member has the first surface and the second surface opposite to each other in the front-rear direction. said tear-off guide having flanking third and fourth surfaces, extending from said third surface to said fourth surface for forming said opening at the rear side of said receiving member; It is desirable to have lines.

According to such a container for absorbent articles, in addition to the first surface and the second surface (front side) of the container member, the third surface and the fourth surface (rear side) are also opened. By providing the part, it is possible to make it easier to take out the absorbent article housed inside the housing member.

In such a container for absorbent articles, it is desirable that the third surface is provided with a pattern representing information relating to at least one of the position and shape of the opening.

According to such a container for absorbent articles, by visually recognizing the pattern, the user can grasp the position where the opening is formed on the rear side of the containing member and the shape of the opening at a glance. As a result, the opening operation of the container can be facilitated.

In such a container for absorbent articles, the containing member is composed of a base sheet in which a paper layer and a resin layer are laminated, and the weight of the paper relative to the total weight of the containing member is It is desirable that the weight ratio of the layer is 50% or more.

According to such a container for absorbent articles, by setting the weight ratio of paper to 50% or more, it is possible to make it easier for users to recognize that the container is an environmentally friendly product. In addition, since the base sheet of the storage member has a resin layer, even though it is a paper product, it is difficult for moisture to permeate the absorbent article stored inside, and it is possible to ensure sufficient moisture resistance. becomes.

In such a container for absorbent articles, the paper layer is provided on the front side of the resin layer in the thickness direction of the base sheet, and the base sheet is provided on the front side of the paper layer. Preferably, a coating layer of water-soluble ink is provided to cover the material sheet.

According to such a container for absorbent articles, even if the layer on the front side in the thickness direction (outer layer) is made of paper, the water resistance of the paper layer can be improved by coating it with the coating layer. can be done. This can prevent water from reaching the absorbent article housed inside the housing member. Moreover, since the strength of the outer layer is increased by providing the covering layer, it is possible to prevent the shape of the housing member from collapsing.

In such a container for absorbent articles, it is desirable that the paper forming the containing member is 100% recycled paper.

According to such a container for absorbent articles, by using recycled paper, the texture and texture of paper can be easily produced in the containing member, and it is easy for the user to recognize that the product is environmentally friendly. can do. In addition, since recycled paper tends to have higher rigidity than normal paper, the shape of the base sheet when folded along the folding guide lines tends to be stable, and the shape of the containing member can be prevented from collapsing. .

In such a container for absorbent articles, it is desirable that the absorbent articles are individually wrapped in a film packaging material and housed in the housing member.

This makes it easier to form the opening.
===Embodiment===

<Basic Configuration of Absorbent Article Container 1>
As a container for absorbent articles according to the present invention, an embodiment will be described by taking as an example a sanitary napkin container 1 (hereinafter also simply referred to as "container 1") for containing a sanitary napkin. However, the absorbent article to be stored in the container 1 is not limited to the sanitary napkin, and may be anything that can be stored in the storage member, such as a disposable diaper, a panty liner, and a light incontinence pad.

FIG. 1 is a schematic perspective view of a sanitary napkin container 1 (container 1) when viewed obliquely from the front. FIG. 2 is a schematic perspective view when the sanitary napkin container 1 (container 1) is viewed obliquely from the rear. FIG. 3 is a diagram illustrating a state in which a plurality of absorbent articles 100 are accommodated inside the container 1. FIG. The containing body 1 has a containing member 10 which is a bag-shaped member, and one or more (plurality) absorbent articles 100 (hereinafter also referred to as "napkin 100") contained in the containing member 10. ing. As shown in FIGS. 1 to 3, the housing 1 (housing member 10) has a vertical direction, a horizontal direction, and a front-back direction that intersect with each other.

(Accommodating member 10)
As shown in FIG. 1, the housing member 10 is a substantially heptahedral container with a triangular roof-shaped upper portion. formed by joining the parts of As a method of folding the base material sheet 11 to form the substantially heptahedron-shaped containing member 10 as shown in FIG. You can use it.

In the present embodiment, the front side surface of the housing member 10 is referred to as the front side surface S1, and the oblique surface provided on the upper side of the front side surface is referred to as the front upper surface S2. Similarly, the rear side surface of the housing member 10 is referred to as a rear side surface S3, and the oblique surface provided on the upper side of the rear side surface is referred to as a rear upper surface S4. The right side surface of the housing member 10 is defined as a right side surface S5, the left side surface as a left side surface S6, and the bottom surface as a bottom surface S7 (see FIGS. 1 and 2).

These surfaces S1 to S7 are formed by bending with reference to the boundaries between adjacent surfaces. For example, the front upper surface S2 (second surface) has a boundary line (FL1 in FIG. 1) between the lower adjacent front surface S1 (first surface) and a predetermined It is formed by being folded at an angle. In the present embodiment, folding guide lines FL (details will be described later) are provided at the positions of the boundary lines that serve as the reference for folding, thereby making it easier to fold the adjacent surfaces.

A cutting guide line 12 is provided on the front side of the housing member 10 . The cutting guide line 12 is arranged from the front side surface S1 (first surface) to the front upper surface S2 (second surface) as shown in FIG. An opening 30 for taking out the napkin 100 is formed by cutting a part of the constituent base sheet 11 (see FIG. 3). In addition, a tear guide wire 13 for forming an opening 30 is provided on the rear side of the housing member 10 in the same manner as the tear guide wire 12 (see FIG. 2). The cutting guide line 13 is arranged from the rear side surface S3 (third surface) to the rear upper surface S4 (fourth surface) as shown in FIG. A specific configuration of the cutting guide wire 12 (13) will be described later.

A pattern 15 is provided on the surface of the housing member 10 . The pattern 15 is provided to allow the user to visually recognize various types of information regarding the container 1 (napkin 100). For example, on the front side S1 of the storage member 10, the name (eg, brand name and sub-brand name) and characteristics (eg, absorbent capacity) of the napkin 100 stored inside, and graphics that make the absorbent article 100 image ( For example, a picture of a napkin), various information about the size of the wearer, etc. are provided as the pattern 15 . In addition, as the pattern 15, display of various authentication marks (not shown) may be provided. The pattern 15 is mainly formed by printing.

FIG. 4 is a diagram for explaining the cross-sectional structure of the base sheet 11 that constitutes the housing member 10. As shown in FIG. The base sheet 11 is a laminated sheet member formed by laminating a plurality of sheet members in the thickness direction. The base sheet 11 of the present embodiment includes an outer layer 11a arranged on the outer side in the thickness direction (the front surface side of the housing member 10) and an inner layer 11b arranged on the inner side in the thickness direction (the rear surface side of the housing member 10). It has a two-layer structure with However, the base sheet 11 may have three or more layers.

At least a portion of the outer layer 11a is made of paper. Here, "paper" is manufactured by agglutinating plant fibers, etc. In a broad sense, in addition to synthetic paper manufactured using synthetic high-molecular substances as raw materials, paper containing fibrous inorganic materials is also included. shall include Since the outer layer 11a is made of a paper material, it is easy for the user to recognize that the container 1 is a so-called "plastic-free" product in which petroleum-derived materials are reduced, and the user can be given an environment-friendly image. The outer layer 11a in this embodiment is desirably made of "paper" made of plant fibers such as pulp fibers, and more desirably, the entire outer layer 11a is made of recycled paper.

At least a portion of the inner layer 11b is made of resin. Here, the "resin" is a synthetic resin made of a polymer compound, and thermoplastic resins such as polyethylene, polypropylene, polyvinyl chloride, polystyrene, polycarbonate, and polyethylene terephthalate (PET) can be used. By providing a layer of resin inside the outer layer 11a made of paper, moisture contained in the atmosphere (including water droplets in the shower room, etc.) is suppressed from entering the container 1 from the outside to the inside. It is possible to easily maintain the moisture resistance of the napkin 100 housed inside.

In addition, since the inner layer 11b, which is the inner surface of the base sheet 11, is made of a thermoplastic resin, the inner surfaces can be thermally welded (heat-sealed) when the housing member 10 is formed. For example, in the housing member 10 shown in FIGS. 1 and 2, the upper end S2e of the front upper surface S2 and the upper end S4e of the rear upper surface S4 face each other with their inner surfaces (inner layers 11b) facing each other. They are joined by a welded portion 50 formed along the left-right direction. By doing so, the inner layer 11b and the surface facing (abutting) the inner layer 11b in the thickness direction can be firmly bonded, and high moisture resistance can be achieved. In addition, in the housing member 10 of the present embodiment, the surface facing the base sheet 11 is also joined by thermal welding at locations other than the welded portion 50, thereby enhancing the overall strength and moisture resistance. there is

In addition, the pattern 15 described above is provided on part of the surface of the base sheet 11 (that is, the outer surface in the thickness direction of the outer layer 11a). A coating layer 16 that covers the surface (outer surface) of the base sheet 11 is provided on the outermost side of the base sheet 11 in the thickness direction. In this specification, such a coating layer 16 is also described as being part of the base sheet 11 .

The coating layer 16 is a layer formed by applying a predetermined liquid over the entire surface of the base sheet 11 . Examples of liquids to be applied include water-soluble inks in which additives are added to water-soluble acrylates. In addition, it is desirable that the coating layer 16 has a non-uniform thickness and has fine irregularities formed on its surface. By forming such a coating layer 16, it is possible to adjust the glossiness of the surface of the base sheet 11 to give a so-called matte tone. That is, the covering layer 16 can be a matte coating layer. Although FIG. 4 shows an example in which the coating layer 16 is formed on the surface side of the pattern 15 in the thickness direction, the pattern 15 and the coating layer 16 may be formed at the same timing. The design 15 may be formed after the coating layer 16 is formed.

(Absorbent article 100)
Next, the absorbent article 100 (napkin 100) housed in the housing member 10 will be described. FIG. 5 is a schematic perspective view of the absorbent article 100 in a state accommodated in the accommodation member 10. FIG. FIG. 6 is a schematic plan view and a schematic cross-sectional view of the absorbent article 100 in an unfolded state.
5 and 6, the napkin 100 has a vertical direction, a horizontal direction, and a thickness direction that intersect each other. The longitudinal direction is the direction corresponding to the longitudinal direction of the napkin 100 in the unfolded state, the side that contacts the lower abdomen of the wearer during use is the front side, and the side that contacts the buttocks is the rear side.
The lateral direction is the direction corresponding to the lateral direction of the absorbent article 100 in the unfolded state. In addition, in the thickness direction, the side in contact with the wearer's skin is the skin side, and the opposite side is the non-skin side.

The napkin 100 comprises a napkin body 110 and a packaging material 150. The napkin main body 110 is a general sanitary napkin, and in the unfolded state of FIG. 6, a skin-side sheet 112, an absorbent body 111, and a non-skin-side sheet 113 are laminated in order from the skin side in the thickness direction. ing. The absorber 111 is a member that absorbs and retains excretory fluid such as menstrual blood, and is made of liquid-absorbent fibers such as pulp fibers or liquid-absorbent fibers containing a superabsorbent polymer (so-called SAP). consists of The skin-side sheet 112 is a liquid-permeable sheet member and can be exemplified by an air-through nonwoven fabric or the like. The non-skin-side sheet 113 is a liquid-impermeable sheet member, and can be exemplified by a polyethylene (PE) resin film or the like. In addition, on the non-skin side surface in the thickness direction of the non-skin side sheet 113, there is a central adhesive portion (broken line in the BB cross-sectional view of FIG. 6) for fixing to the wearer's underwear when the napkin body 110 is used. shown) are provided. The shape of the napkin 100 is not limited to that shown in FIG. 6. For example, the shape of the napkin 100 may be different from that shown in FIG.

The packaging material 150 is a sheet member that individually wraps the napkin main body 110, and is formed of various films such as a non-woven fabric laminated film, a plastic film, and a nylon film. The packaging material 150 is joined to the napkin main body 110 via the protective sheet 160 in a state of being overlaid on the non-skin side in the thickness direction.

The protective sheet 160 is a sheet member provided on the non-skin side of the napkin body 110 . The skin side surface of the protective sheet 160 is subjected to peeling processing using silicone resin or the like, and is detachably attached to the central adhesive portion of the napkin body 110 . On the other hand, the non-skin side of the protective sheet 160 is joined to the packaging material 150 .

The napkin 100 is housed in the housing member 10 in an individually wrapped state as shown in FIG. When the napkin 100 is individually wrapped, from the unfolded state shown in FIG. 6, the second folded portion F2 along the width direction and the first folded portion F1 are folded so that the skin side faces inside. The napkin body 110 and the wrapping material 150 are sequentially folded. Then, in the folded state, both ends sw in the width direction of the packaging material 150 are subjected to a joining process such as heat sealing, and the ends in the longitudinal direction of the packaging material 150 are locked using a fastening tape 170 or the like. Then, it becomes an individual packaging state as shown in FIG.

A plurality of individually wrapped napkins 100 are housed inside the housing member 10 . Specifically, as shown in FIG. 3 , a plurality of napkins 100 are accommodated in a state of being stacked in the thickness direction along the left-right direction of the accommodating member 10 , and distributed on the market as the sanitary napkin container 1 . . When using the napkin 100, the individually wrapped napkin 100 is individually taken out from the opening 30 formed in the upper part of the storage member 10, and after unfolding as shown in FIG. The protective sheet 160 is removed before use.

<Regarding the cutting guide line 12>
Details of the cutting guide line 12 provided on the housing member 10 will be described. Note that the cutting guide wire 13 has substantially the same configuration as the cutting guide wire 12, so the description thereof is omitted here. FIG. 7 is a diagram illustrating the arrangement of the cutting guide lines 12 and the folding guide lines FL1. The cutting guide line 12 is a perforated line formed by arranging a plurality of cuts 12S at predetermined intervals (g12S), and extends from the front side surface S1 (first surface) of the housing member 10 to the front upper surface. They are arranged in a substantially U shape as shown in FIG. 7 over S2 (second surface). That is, the cutting guide line 12 is arranged so as to straddle the boundary line between the front side surface S1 (first surface) and the front upper surface S2 (second surface).

Each cut 12S is a slit that penetrates the base sheet 11 (and the coating layer 16) shown in FIG. 4 from the skin side to the non-skin side in the thickness direction. It is formed by pressing a blade for forming an incision (so-called perforating blade, etc.) in the thickness direction. Since the cuts 12S are arranged intermittently, the base sheet 11 can be easily cut along the cutting guide line 12, forming an opening 30 having the cutting guide line 12 as an outer edge. can be made easier. Note that the cut 12S does not necessarily have to penetrate the base sheet 11 in the thickness direction, and may not penetrate in the thickness direction. For example, of the base sheet 11, only the outer layer 11a may be penetrated, and the inner layer 11b may not be penetrated. With such a configuration, it becomes easier to prevent moisture in the atmosphere from permeating the cutouts 12S and entering the storage member 10, and the moisture resistance of the absorbent article 100 can be further enhanced. Become.

By the way, as described above, at least a portion (the outer layer 11a of the base sheet 11) of the housing member 10 of the present embodiment is made of paper material. Such a paper package is harder and less deformable than a conventional film package made of polyethylene resin or the like. Therefore, in the present embodiment, folding guide lines FL are provided on the boundary lines of the surfaces S1 to S7 of the containing member 10 to make it easier to fold the base sheet 11, thereby forming the containing member 10 into a substantially heptahedral shape as shown in FIG. Makes it easy to shape. By stabilizing the shape of the containing member 10 , it is possible to facilitate the operation of taking out the absorbent article 100 (the napkin 100 ) from the interior of the containing member 10 through the opening 30 .

The folding guide lines FL are formed by compressing the base sheet 11 in the thickness direction during the manufacturing process of the housing member 10 . For example, before forming the surfaces S1 to S7 by folding the planar base sheet 11, the base sheet 11 is preliminarily pressed into a belt shape having a predetermined width (tFL) along the boundary line to be folded. By placing it, the base sheet 11 can be easily folded along the belt-like pressed portion. In FIG. 7, a folding guide line FL1 having a width tFL1 is formed along the boundary line between the front side surface S1 (first surface) and the front side upper surface S2 (second surface).

When the housing member 10 is actually manufactured, after the folding guide lines FL are formed on the planar base sheet 11, each surface is folded along the folding guide lines FL. However, in this embodiment, since the cutting guide line 12 is arranged so as to straddle the boundary between the front side surface S1 (first surface) and the front side top surface S2 (second surface), the cutting guide line 12 itself In some cases, the cutting guide wire 12 is torn due to the bending force acting on it. In addition, while the user who purchased the container 1 keeps it at home or the like, the notch 12S spreads under the influence of the folding guide line FL, and the opening 30 is partially opened before the container 1 is opened. may be lost.
In such a case, the moisture resistance of the containing body 1 may be impaired, and the quality of the absorbent article 100 contained inside the containing member 10 may deteriorate.

Therefore, in the housing member 10 of the present embodiment, the plurality of cuts 12S forming the cutting guide lines 12 and the folding guide lines FL1 are arranged so as not to overlap each other. As a result, it becomes difficult for the bending force to act directly on each of the cuts 12S, and it is possible to prevent the cuts 12S from widening and opening a part of the opening 30 before the container 1 is opened. . Therefore, high moisture resistance can be achieved in the container 1 made of paper in which the shape of the opening 30 and the like can be easily maintained and the absorbent article 100 can be easily taken out.

As a specific method for preventing the notch 12S and the folding guide line FL1 from overlapping each other, a discontinuous portion dc is provided in the folding guide line FL1 in the left-right direction, and the discontinuous portion dc and the cutting guide line 12 are separated. There is a method of preventing overlap with the notch 12S. In FIG. 7, two discontinuous portions dc are provided in which part of the folding guide line FL1 provided along the horizontal direction is discontinuous in the horizontal direction (part of the interval gdc). A cutting guide line 12 (notch 12S) is arranged at a position overlapping with the discontinuous portion dc. At the discontinuous portion dc, since the bending between the front side surface S1 (first surface) and the front side upper surface S2 (second surface) becomes loose, it is difficult for a force to act on the cutting guide line 12 (notch 12S). As a result, it is possible to easily prevent the notch 12S from widening and opening a part of the opening 30. As shown in FIG. Further, since the discontinuous portion dc is formed so as to have a predetermined interval gdc in the left-right direction, even if the formation position of the cutting guide line 12 is slightly shifted in the left-right direction during the manufacturing process of the housing member 10, the cutting will still occur. 12S and the folding guide line FL1 are unlikely to overlap, and opening of the opening 30 before the container 1 is unsealed is easily suppressed. Thereby, the moisture resistance of the container 1 can be further improved.

At this time, the interval g12S (the vertical interval in FIG. 7) between the two

adjacent cuts

12S, 12S is preferably larger than the width tFL1 (the vertical width in FIG. 7) of the folding guide line FL1 (g12S> tFL1). By making the interval between the

adjacent cuts

12S, 12S as wide as possible compared to the width of the folding guide line, the

cuts

12S, 12S are likely to be prevented from being connected, and the opening 30 is opened before opening. It becomes easier to suppress. Further, even if the folding guide line FL1 is not provided with the discontinuous portion dc and is provided continuously in the left-right direction, the interval g12S between the

cuts

12S and 12S is the folding guide line. If the width tFL1 of the line FL1 is wider than the width tFL1 (see FIG. 9), the probability that the cut 12S and the folding guide line FL1 overlap can be reduced.

However, the space g12S (the space in the vertical direction) between the two

adjacent cuts

12S, 12S may be equal to or less than the width tFL1 (the width in the vertical direction) of the folding guide line FL1 (g12S≦tFL1). When recycled paper is used as the base sheet 11 that constitutes the housing member 10, the base sheet 11 itself tends to harden, making it difficult to tear the base sheet 11 along the cutting guide line 12 to form the opening 30. may become In such a case, the operation of forming the opening 30 can be facilitated by making the interval g12S between the

cuts

12S, 12S as narrow as possible. In addition, as described above, in this embodiment,
The discontinuous portion dc provided on the folding guide line FL1 has a predetermined interval gdc in the left-right direction, and even if the cutting guide line 12 is misaligned to some extent, the probability of overlapping with the folding guide line FL1 is low. . Therefore, even if the gap g12S between the

cuts

12S, 12S is reduced, it is possible to prevent the opening 30 from opening before opening.

In addition, in the housing member 10, the angle formed by the front side surface S1 (first surface) and the front side upper surface S2 (second surface) bent with respect to the folding guide line FL1 is 90 degrees or more (obtuse angle). there is FIG. 8 is a diagram showing the cross-sectional shape of the housing member 10 when viewed from the left-right direction.
As shown in FIG. 8, the angle α formed between the front side surface S1 (first surface) and the front upper surface S2 (second surface) (the angle formed by the front side surface S1 and the front upper surface S2, whichever is smaller) angle) is greater than 90 degrees. If the angle α were to be less than 90 degrees, it would be necessary to fold the base sheet 11 in a planar state by 90 degrees or more with respect to the folding guide line FL1. A large bending force also acts on the cutting guide wire 12 that is present, and there is a risk that the cut 12S will become easier to open.

In contrast, in the present embodiment, the angle α is 90 degrees or more, and the angle at which the base sheet 11 is folded (the angle at which the front upper surface S2 is folded with respect to the front side surface S1) can be reduced. Therefore, the bending angle with respect to the folding guide line FL1 becomes loose, and the force acting on the cutting guide line 12 can be reduced accordingly. This makes it easier to prevent the opening 30 from being opened before it is unsealed.

Further, the folding guide line FL1 is also formed in the region between the left and right pair of cutting

guide lines

12, 12 arranged across the boundary between the front side surface S1 (first surface) and the front side upper surface S2 (second surface). is provided. In FIG. 7, a bending guide line FL1c is provided at a portion sandwiched between a pair of cutting

guide lines

12, 12 in the left-right direction. This portion of the housing member 10 is cut along the cutting guide line 12 when the opening 30 is formed. Since the closed state is maintained, it can function as a cover (lid) for covering the opening 30 as it is. For example, if the unsealed storage body 1 is placed in a shower room or the like, water droplets or the like are likely to enter the interior of the storage member 10 from the opening 30, and the liquid absorbency of the absorbent article 100 may deteriorate. There is On the other hand, the portion cut along the cut-off guide line 12 functions as a cover (lid) to close the opening 30, thereby making it easier to suppress the infiltration of moisture and the like. Therefore, it is possible to easily maintain the moisture resistance of the container 1 .

In addition, the storage member 10 of the present embodiment can also form the opening 30 on the rear side in the front-rear direction. That is, the housing member 10 has a cutting guide line 13 extending from the rear side surface S3 (third surface) to the rear upper surface S4 (fourth surface) (see FIG. 2). An opening 30 similar to the front side is formed by cutting a portion of the housing member 10 along. By providing the openings 30 on the front and rear sides of the storage member 10, it is possible to make it easier to take out the absorbent article 100 stored therein. Since the outer layer 11a of the base sheet 11 constituting the housing member 10 is made of paper and has a high strength, even if the openings 30 are provided at the front and back, the shape of the housing member 10 (heptahedral shape) is It is difficult to collapse, and the operation of taking out the absorbent article 100 can be stably performed.

Note that the rear side surface S3 of the housing member 10 is provided with a display for indicating information regarding at least one of the position and shape of the opening 30 formed on the rear side surface S3 (and the rear upper surface S4). is preferred. In FIG. 2 , a pattern (shaded portion) bordering the cutting guide line 13 and the letters “OPEN” in the area surrounded by the cutting guide line 13 are provided as a pattern 15p indicating the position and shape of the opening 30. It is By visually recognizing the pattern 15p, the user can grasp the position where the opening 30 is formed on the rear side of the container 10 and the shape of the opening 30 at a glance, and the operation of opening the container 1 can be performed. can make it easier to do. In addition, since such a pattern 15p is provided on the rear side S3, it is not necessary to provide an equivalent pattern on the front side S1. It is possible to increase the space for displaying the name. This makes it easier for the user to recognize the container 1 as a product.

Also, in the housing member 10, the ratio of the weight of the paper portion to the total weight is preferably 50% or more. In the case of FIG. 4, the base sheet 11 has a laminated structure of an outer layer 11a made of paper and an inner layer 11b made of resin. 50% or more. Depending on the country, products with a weight percentage of paper of 50% or more can be labeled as paper products or can be disposed of as paper waste, so the weight percentage of paper is 50%. The above is likely to serve as an indicator that the product is a paper package product. Therefore, by setting the weight ratio of the paper to 50% or more, it is possible to make it easier for the user to recognize that the container 1 of the present embodiment is an environmentally friendly product. In addition, since the inner layer 11b of the storage member 10 is made of a liquid-impermeable resin such as polyethylene, the absorbent article 100 stored therein does not easily get wet and has sufficient moisture resistance even though it is a paper product. It is possible to secure it.

In addition, a coating layer 16 (matte coating) made of water-soluble ink or the like is provided on the outer side (front side) in the thickness direction of the outer layer 11a made of paper. By providing such a coating layer 16, even if the outer layer 11a is made of paper, it is possible to increase the water resistance of the outer layer 11a. Even in such a case, it is possible to prevent moisture from reaching the absorbent article 100 accommodated inside. That is, the moisture resistance of the container 1 can be improved. Moreover, since the strength of the outer layer 11a itself is increased by the coating layer 16, the shape of the housing member 10 is less likely to collapse. By providing unevenness on the surface of the coating layer 16, the surface of the housing member 10 can be made to have a so-called matte finish, and the visibility of the design 15 provided on the housing member 10 can be improved by suppressing the reflection of light. can be enhanced.

Furthermore, it is more preferable that the paper forming the outer layer 11a of the base sheet 11 is 100% recycled paper. By using recycled paper, the texture and texture of the paper can be easily produced in the housing member 10, and the user can easily recognize that the product is an environmentally friendly product. In addition, since recycled paper tends to be more rigid than ordinary paper, it is easy to stabilize the shape of the base sheet 11 when the base sheet 11 is folded along the folding guide line FL, and the shape of the housing member 10 is less likely to collapse. can be done.

In addition, in the container 1, the absorbent article 100 is individually wrapped in a packaging material 150 such as a film, and is contained in the container 10. As shown in FIG. Since the absorbent article 100 (napkin 100) is individually wrapped by the wrapping material 150, the absorbent body 111 and the like of the absorbent article 100 are less likely to be exposed to the atmosphere, and absorb moisture in the atmosphere. It is possible to suppress deterioration of performance and the like. Therefore, even after the storage member 10 is opened (after the opening 30 is formed), it is possible to easily maintain the absorbent performance of the plurality of absorbent articles 100 stored therein in a good state. .

When storing the individually wrapped absorbent articles 100 in the storing member 10, as shown in FIG. The storage member is accommodated so that the thickness direction is aligned with the left-right direction of the storage member. In other words, the plurality of absorbent articles 100 are stacked in the thickness direction such that the thickness direction of the individually wrapped absorbent articles 100 intersects the normal direction of the front side surface S1 of the housing member 10. , are housed in the housing member 10 .

When forming the opening 30 in the container 1, an operation of cutting off the tear guide wire 12 is performed by pushing the area surrounded by the tear guide wire 12 of the container member 10 inward from the outside. If the absorbent article 100 is stored such that the thickness direction of the absorbent article 100 is parallel to the normal direction of the front side surface S1 of the storage member 10, the area surrounded by the cutting guide line 12 When the absorbent article 100 is pushed in from the outside, the absorbent article 100 accommodated inside interferes with the cutting guide wire 12, which may make it difficult to break. On the other hand, when the absorbent article 100 is stored so that the thickness direction of the absorbent article 100 intersects the normal direction of the front side surface S1 of the storage member 10, the absorbent articles 100 stacked in the thickness direction , 100 are formed. The presence of this space makes it difficult for the operation of pushing the area surrounded by the cutting guide line 12 from the outside to the inside to be interfered with, making it easier to cut the cutting guide line 12 . This makes it easier to form the opening 30 .

<Modification>
In the above-described embodiment, the folding guide line FL1 provided in the housing member 10 has a discontinuous portion dc, and an example in which the discontinuous portion dc and the cutting guide line 12 are arranged to overlap will be described. However, it is also possible to modify the arrangement of the folding guide lines FL1 and the cutting guide lines 12 as follows. FIG. 9 is a diagram illustrating a modification of the arrangement of the cutting guide lines 12 and the folding guide lines FL1. In addition, in this modified example, the configuration other than the cutting guide line 12 and the folding guide line FL1 is substantially the same as that of the container 1 shown in FIG.

In this modified example, the folding guide line FL1 is provided continuously from one end side to the other end side in the left-right direction. That is, the folding guide line FL1 of the modified example does not have the discontinuous portion dc. Further, in the cutting guide line 12 of this modification, the interval g12S between two

adjacent cuts

12S, 12S is larger than the width tFL1 of the folding guide line FL1 (g12S>tFL1), and the distance between the

adjacent cuts

12S, 12S A folding guide line FL1 is arranged therebetween. In other words, the cuts 12S are arranged above and below the folding guide line FL1 in the vertical direction so as not to overlap the folding guide line FL1. That is, also in the housing member 10 of the modified example, the plurality of cuts 12S forming the cutting guide line 12 and the folding guide line FL1 do not overlap.

As a result, it becomes difficult for a force due to bending to directly act on the cutting guide wire 12, and it is possible to prevent the notch 12S from widening and opening a part of the opening 30 before the container 1 is opened. . In addition, since the folding guide line FL1 is continuous, it is easy to form a crease at the boundary between the front side surface S1 (first surface) and the front side upper surface S2 (second surface). It can be made more stable.
