Detailed Description

< first utility model >

The following embodiments include not only the indispensable structure of the present invention but also an alternative and preferable structure of the absorbent article shown in the drawings. Hereinafter, an embodiment of a sanitary napkin 410 as an example of an absorbent article of the present invention will be described with reference to the drawings. The sanitary napkin 410 has a longitudinal direction (first direction or second direction) Y, a transverse direction (second direction or first direction) X, and a thickness direction Z.

Referring to fig. 1 to 3, the sanitary napkin 410 has a longitudinal centerline (first centerline) P bisecting the dimension in the transverse direction thereof and a transverse centerline (first centerline) Q bisecting the dimension in the longitudinal direction Y, and the sanitary napkin 410 includes: a skin-facing surface side and a non-skin-facing surface side opposite thereto; a liquid-permeable top sheet 411 positioned on the skin-facing surface side; a liquid-impermeable back sheet 412 positioned on the non-skin-facing surface side; and a liquid-absorbent body 420 positioned between the top sheet 411 and the back sheet 412.

The sanitary napkin 410 has a substantially cross-like shape, and its outline (outer contour) is defined by a first edge 410a and a second edge 410b that are concavely curved inward in the longitudinal direction Y, and a first side edge 410c and a second side edge 410d that are convexly curved outward in the transverse direction X at a portion intersecting the transverse center line Q.

Although not shown, an intermediate sheet made of a relatively large bulk fiber nonwoven fabric may be disposed between the topsheet 411 and the absorbent member 420 in order to improve the flexibility of the sanitary napkin 410.

For convenience of explanation, the sanitary napkin 410 is divided in the longitudinal direction Y into a first end region 431 located on the first end edge 410a side, a second end region 432 located on the second end edge 410b side, and a middle region 433 located between the first end region 431 and the second end region 432. The sanitary napkin 410 is divided in the transverse direction X into a first side region 434 between the longitudinal centerline P and the first side edge 410c, and a second side region 435 between the longitudinal centerline P and the second side edge 410 d. The first side edge 410c and the second side edge 410d (the first side edge portion 417 and the second side edge portion 418) are bluff shapes having a plurality of constrictions and have different shapes from each other in the first end region 431, the second end region 432, and the middle region 433, respectively. The first end region 431, the second end region 432, and the middle region 433 may each have a longitudinal dimension approximately trisecting the dimension in the longitudinal direction Y of the sanitary napkin 410, and the first end region 431, the second end region 432, and the middle region 433 may each have a dimension of 20 to 50% of the longitudinal dimension of the sanitary napkin 410.

The absorbent body 420 has an outer shape along the outer shape line of the sanitary napkin 410, and has: a first end edge 420a opposite the first end edge 410a and a second end edge 420b opposite the second end edge 410 b; and a first side edge 420c and a second side edge 420d extending in the longitudinal direction between the first end edge 410a and the second end edge 410 b. The first side edge 420c and the second side edge 420d of the absorber 420 have a bluff shape including a plurality of constrictions so as to follow the shape of the first side edge 410c and the second side edge 410d of the sanitary napkin 410.

The absorbent body 420 comprises a liquid-absorbent core imparted with a desired shape, and is preferably covered with a core-covering sheet. The liquid-absorbent core has a core composed of water-insoluble superabsorbent polymer particles (SAP particles); an absorbent and dispersible material made of cellulose fibers such as wood pulp (pulp fibers) and rayon fibers.

The topsheet 411 and the backsheet 412 extend outward from the outer periphery of the absorbent body 420, and a pair of side sheets 414 extending in the longitudinal direction Y are arranged on the skin-facing surface side of the topsheet so as to face each other in the lateral direction. A pair of side sheets 414 are joined to the surface sheet 411 via side bonding portions.

The sanitary napkin 410 has: a first end 415 and a second end 416 (first edge or second edge) that are opposite to each other in the longitudinal direction Y and extend in the lateral direction X; and a first side edge portion 417 and a second side edge portion 418 (first edge portion or second edge portion) which are opposed to each other in the lateral direction X and extend in the longitudinal direction Y. Each of the first side edge portion 417 and the second side edge portion 418 has a wing portion 419 projecting outward in the transverse direction X. The first end edge 420a and the second end edge 420b of the absorber 420 are located at the first end portion 415 and the second end portion 416, respectively, and the first side edge 420c and the second side edge 420d of the absorber 420 are located at the first side edge portion 417 and the second side edge portion 418, respectively. The sanitary napkin 410 further has an outer peripheral edge portion extending from the outer peripheral edge of the absorbent member 420. The sheets stacked on each other to form the outer peripheral edge portion are joined to each other via an outer peripheral seal portion 407 located along the outer peripheral edge of the sanitary napkin 410. It can be said that the peripheral seal portion 407 where the sheet is heat-welded is located on the periphery of the sanitary napkin 410, whereby the outer shape thereof becomes clear.

The sanitary napkin 410 is stored in the individual package body in a state of being folded into three. The individual package is formed by folding the package sheet and the sanitary napkin 410, and the sanitary napkin 410 has a first folding line 401 and a second folding line 402 extending in the longitudinal direction Y formed when folded. The first bend line 401 and the second bend line 402 extend in the longitudinal direction Y so as to overlap base end portions of the pair of wing portions 419.

The region between the wings 419 of the absorbent body 420 is a region opposed to the vaginal opening of the wearer, and a middle-high portion 421 of the absorbent body 420, which is thicker than the other portions, is located in this region. Since the absorbent body 420 has higher rigidity or semi-rigidity than the sheet material constituting the sanitary napkin 410 and the absorbent body 420 has a desired thickness dimension, the outline of the absorbent body 420 can be seen through from the front side and the back side of the sanitary napkin 410 via the front sheet 411 and the back sheet 412. When the sanitary napkin 410 does not have the flap portion 419, it is preferably disposed between the first folding line 401 and the second folding line 402 of the sanitary napkin 410 in the longitudinal direction Y.

Although not shown, a plurality of fastening regions are disposed on the back surface side of the sanitary napkin 410. The plurality of fastening regions are configured to fasten the sanitary napkin 410 to a garment such as underwear, and are formed of a plurality of linear adhesives or pressure-sensitive adhesives extending in the longitudinal direction Y.

As the top sheet 411, a sheet permeable to liquid components contained in body fluids, such as an open plastic film, woven fabric, or nonwoven fabric, can be preferably used. As the back sheet 412, a thermoplastic resin film mainly composed of a thermoplastic resin such as polyethylene or polypropylene can be preferably used; a thermoplastic resin film to which air permeability is imparted. The side sheet 414 can use the same sheet material as the surface sheet 411. However, in order to make it difficult for body fluid to flow to the outside of the sanitary napkin 410, a sheet material having hydrophobic or water-repellent properties is preferably used.

The joining of the sheets in the outer peripheral seal portion 407 can be performed by the following joining alone or in combination: adhesive-based bonding; joining by a known welding means such as ultrasonic welding, thermal welding, laser welding, and high-frequency wave welding; and bonding based on imprint processing. The sheets stacked in the thickness direction are bonded to each other with an adhesive such as a hot melt adhesive. Examples of the method of applying the hot-melt adhesive include various known coating methods such as spiral coating, curtain coating, and spray coating.

The decorative region 440 is disposed on the back sheet 412. The decorative region 440 has a plurality of decorative portions 441 that are colored. The decorative portion 441 is substantially triangular in size and is disposed independently of each other only in the first side region 434 out of the first side region 434 and the second side region 435 of the sanitary napkin 410. The decorative portion 441 has a plurality of placement modes such as a mode of being disposed at intervals in the longitudinal direction Y and the lateral direction X, a mode of being partially overlapped with each other in a plan view, and the like. The decorative region 440 may be disposed on either the inner surface or the outer surface of the back sheet 412. However, in order to prevent the printed ink from falling off, the decorative region 440 is preferably disposed on the inner surface of the back sheet 412.

The "white" in the present specification can be exemplified by a color expressed as "N9.5" in the munsell color system and colors expressed as "255, and 255" in the RGB color space, that is, so-called "pure white". In addition, colors of the same system color as "pure white", specifically, colors having a color difference of 0 or more and less than 12 from "pure white" are also included in "white". Colors other than "white" are colored, and cold colors fall into this category. Specifically, a color having a color difference of 40 or more from "white" defined above is preferable. The determination method of white color can be compared with a color difference with respect to white color, and can be determined using, for example, color difference CR-300 manufactured by KONICA MINOLTA (KONICA MINOLTA).

The decorative portion 441 may have a shape other than the illustrated shape, such as a substantially circular shape, a substantially oval shape, a substantially rectangular shape, a substantially trapezoidal shape, a substantially star shape, a flower shape, and various other well-known decorative patterns, characters, and the like, as long as the decorative portion achieves the technical effects of the present invention described later. The decorative portion 441 is colored as a whole, and the colored color may be any color that can be visually recognized clearly from the sheet material and the absorbent core constituting the sanitary napkin, which are colored white by adding a white pigment such as titanium oxide, and for example, a color tone that attracts the attention of the wearer, such as red, blue, yellow, or green, is preferable. In addition, when the entire back sheet 412 is colored in a color other than white, the decorative portion 441 is preferably colored in a color complementary to the colored color.

The decorative portion 441 may be designed so that only the outer contour line of the absorbent body 420 superposed thereon is visually unclear, instead of being colored as a whole, only the outer contour line may be colored. When the outer surface of the back sheet 412 is formed of a nonwoven fabric, an uncolored uneven print pattern may be formed. Even in this printed pattern, the shape of the outer contour line of the overlapped absorber 420 can be blurred by refraction of light or the like, and the wearer or the like cannot visually confirm the pattern clearly.

The decorative region 440 is disposed only on the first side edge 417 of the first side edge 417 and the second side edge 418, and is located at a position overlapping only the first side edge 420c of the first side edge 420c and the second side edge 420d of the absorber 420 in a plan view. Since the colored decorative region 440 overlaps only the first side edge 420c of the absorber 420 in a plan view and only the second side edge 420d of the first side edge 420c and the second side edge 420d of the absorber 420 is clearly seen through from the front side and the back side, the wearer or the wearer-assistant cannot accurately grasp the outline of the absorber 420 even if the wearer or the wearer can recognize the existence thereof. Therefore, for example, even when the absorbent body 420 is displaced with respect to the longitudinal centerline P in a high-speed production line of the sanitary napkin 410, that is, even when the absorbent body is disposed so as to be biased toward the first side edge 420c or the second side edge 420d, the displacement is not recognized by the wearer or the like.

At first glance, the wearer or the like does not recognize the sanitary napkin 410 as a product in which the absorber 420 is displaced from the regular position, and therefore, the product in which the displacement occurs does not need to be handled as a defective product in the manufacturing process, and the burden of product cost due to the production line stoppage when a defective product occurs and the production line waste can be reduced.

When the wearer or the like takes out the sanitary napkin 410 from the individual package, the wearer can instantly recognize the outline of the sanitary napkin 410 and the outline of the absorbent body 420 and grasp the distance between the outlines. In this case, when the absorbent body 420 is seen to be displaced in the lateral direction X, even if there is no problem in the quality and absorption performance of the absorbent body, the quality of the product itself may be poor, and the product may be rough. In fact, even if the absorber 420 is slightly displaced in the lateral direction X, quality problems such as deterioration of the absorption performance do not occur, but it is preferable to grasp that the absorber 420 is not displaced in the lateral direction X as much as possible so as not to cause quality misunderstanding to the wearer. Therefore, it is preferable that the wearer does not recognize the outline of the absorbent body 420 and the distance between the outline of the sanitary napkin 410 and the outline of the absorbent body 420 at first sight.

In order not to make the wearer grasp the distance between the outline of the absorbent body 420 and the outline of the sanitary napkin 410, it is also conceivable to arrange the decorative region 440 so as to overlap not only the first side edge 420c but also the second side edge 420d in plan view, but in this case, the first side edge 420c and the second side edge 420d of the absorbent body 420 cannot be grasped, and there is a concern that the wearer or the like may be given a feeling of uneasiness in absorbing body fluids, particularly in side leakage of body fluids.

In the sanitary napkin 410 of the present embodiment, since the decorative region 440 is located only at the first side edge 417 of the back sheet 412, the first side edge 420c of the absorber 420 is not visually recognized, and even if the absorber 420 is slightly displaced in the lateral direction X, the appearance of the absorber 420 and the distance between the appearance of the sanitary napkin 410 and the appearance of the absorber 420 are not grasped and the impression of displacement is not given, so that the feeling of uneasiness regarding the absorption performance, quality, and the like can be reduced. Further, since the second side edge 420d of the absorbent body 420 positioned at the second side edge portion 418 is clearly visually recognized, the wearer can be less likely to feel uneasy about the absorption property and the side leakage of bodily fluids without giving an impression that the absorbent body 420 is narrowed.

Further, since the absorber 420 has a required thickness dimension, even when a step is formed along the first side edge 420d of the absorber 420 overlapping the decorative region 440, the decorative region 440 of the first side edge 417 attracts the attention of the wearer or the like and the step can be made inconspicuous because the first side edge 417 and the second side edge 418 have asymmetric designs, and thus, the positional deviation of the absorber 420 can be suppressed from being grasped.

The decorative region 440 is a region that is located at least at the first side edge 417 and overlaps with the first side edge 420c of the absorber 420 in a plan view, and the decorative region 440 may be disposed over the entire area in the longitudinal direction Y of the first side region 434. In this case, the shape of the absorber 420 on the first side edge 420c side is made difficult to visually recognize, and thus the outer shape of the absorber 420 can be made difficult to grasp. The decorative region 440 may not be disposed in a portion including the wing portion 419 and located outside the first side edge 420c in the transverse direction X, as long as it overlaps the first side edge 420c of the absorber 420 in the first side edge portion 417 in a plan view.

The inner edge 440a of the decorative region 440 shown by a thick one-dot chain line in fig. 4, that is, a virtual line formed by discontinuously connecting portions of the plurality of decorative portions 441 located on the side of the longitudinal centerline P in the longitudinal direction Y has a shape undulating with respect to the longitudinal centerline P. Specifically, referring to fig. 5 (a), the decorative portions 441 are arranged to have random sizes, positions, and orientations, and a spacing dimension R401 in the transverse direction X between the tip of an arbitrary decorative portion 441A and the longitudinal centerline P and a spacing dimension R402 in the transverse direction X between the tip of an arbitrary decorative portion 441B and the longitudinal centerline P are different from each other. Since the decorative portions 441 are arranged irregularly, the plural decorative portions 441 arranged in the longitudinal direction Y are all different in the interval dimension, and the inner edge 440a may be said to extend discontinuously in a zigzag manner in the longitudinal direction Y. Since the inner edge 440a of the decorative region 440 has a wavy shape with respect to the longitudinal centerline P, the wearer's attention can be attracted more strongly to the decorative region 440 than in the case where the inner edge is linear, and the shape of the first side edge 420c of the absorber 420 extending in the longitudinal direction Y can be suppressed from being grasped.

The decorative portion 441 of the decorative region 440 has a substantially triangular shape and a sharp shape extending from the first side edge 410c side of the first side edge portion 417 toward the longitudinal centerline P. Since the decorative portion 44 has such a shape, the area of the decorative portion 441 forming the decorative region 440 on the first side edge 410c side of the first side edge 420c of the absorber 420 is relatively larger than the area on the longitudinal centerline P side, and therefore the total area of the decorative portion 441 can be suppressed and the outer shape of the absorber 420 can be effectively prevented from being grasped. Further, compared to the case where the decorative portion 441 is circular and extends sharply outward in the longitudinal direction Y, the line of sight of the wearer or the like is directed toward the longitudinal centerline P unconsciously more toward the longitudinal centerline P than toward the first side edge 420c of the absorbent body 420 by the tip of the decorative portion 441, and therefore, the outer shape of the first side edge 420c can be suppressed from being visually perceived.

Referring to fig. 2, when viewed from the front surface of the sanitary napkin 410, the absorbent body 420 is positioned above the back sheet 412 where the decorative region 440 is located, and therefore, the portion of the decorative region 440 located on the side of the longitudinal centerline P is difficult to visually confirm through the absorbent body 420. Further, when the absorber 420 is colored white, for example, by the color colored by the decorative region 440, the white color may be emphasized and seen, and there is a concern that: the shape of the first side edge 420c becomes clear instead by the decorative region 440 being seen through at the outer side of the first side edge 420c in the transverse direction X.

In the present embodiment, since the decorative portions 441 have shapes independent of each other, the decorative region 440 has a plurality of non-decorative portions 442 located between the plurality of decorative portions 441 and where the decorative portions 441 are not disposed. Since the portions where the first side edge 420c of the absorber 420 is difficult to visually confirm by the plurality of decorative portions 441 and the portions where the first side edge 420c is not clearly visually confirmed by the plurality of non-decorative portions 442 are mixed, the shape of the first side edge 420c cannot be clearly visually confirmed, and the appearance of the absorber 420 can be suppressed from being grasped.

The dimension in the longitudinal direction Y of the decorative region 440 is at least half, preferably 60% or more, and preferably 80% or more, of the dimension L1 in the longitudinal direction Y of the first side edge 420c of the absorbent body 420. Since the dimension in the longitudinal direction Y of the decorative region 440 is equal to or larger than half the dimension L1 in the longitudinal direction Y of the first side edge 420c of the absorber 420, most of the first side edge 420c of the absorber 420 passes through the decorative region 440 and is difficult to visually confirm, and the appearance can be prevented from being grasped.

In addition, in the decoration region 440, the decoration portions 441 are arranged densely at the first side edge 410c side than at the longitudinal center line P side. By arranging the decorative portions 441 densely in the lateral direction X, the decorative region 440 has decorative elements due to contrast in color depth, and therefore draws attention of the wearer, and it can be said that the first side edge 420c of the absorber 420 is difficult to clearly visually confirm.

In most of the decorative portion 441, the colored color gradually becomes darker toward the inside in the lateral direction X. In this way, the decorative region 440 has an irregular design due to the gradient of the color of the decorative portion 441, and the wearer or the like can hardly grasp the outer shape of the absorber 420 at first sight.

Referring to fig. 5 (b), a part of the decorative region 440 overlaps a part of the first end edge 420a of the absorber 420 extending in the transverse direction X in a plan view. Specifically, the

decorative portions

441D, 441E, 441F of the decorative portion 441 overlap with a portion of the first end edge 420 a. In this way, the decorative region 440 overlaps not only the first side edge 420c extending in the longitudinal direction Y but also a part of the first end edge 420a extending in the lateral direction X intersecting with the first side edge 420c, whereby the appearance of the absorbent body 420 can be more effectively suppressed from being grasped.

The first side edge portion 417 and the second side edge portion 418 have a non-streamlined shape having a plurality of narrowed portions, and have different shapes in the first end region 431, the second end region 432, and the middle region 433 of the sanitary napkin 410, respectively. Referring to fig. 4, the dimension W401 of the first side edge 410c and the second side edge 410d in the first end region 431 in the transverse direction X from the first side edge 420c and the second side edge 420d of the absorber 420, the dimension W403 of the first side edge 410c and the second side edge 410d in the second end region 432 in the transverse direction from the first side edge 420c and the second side edge 420d of the absorber 420, and the dimension W402 of the first side edge 410c and the second side edge 410d in the intermediate region 433 in the transverse direction from the first side edge 420c and the second side edge 420d of the absorber 420 are different from each other. Since the interval dimensions W401 to W403 are different from each other, the area of the decorative region 440 (the total area of the decorative portion 441) located at the first side edge portion 417 is different in the regions 431 to 433 in the longitudinal direction Y, so that the design of the decorative region 440 can be improved to attract attention of a wearer or the like, and the shape and position of the first side edge 420c of the absorber 420 can be kept from being visually recognized.

Fig. 6 is a schematic plan view of an example of a modification of the sanitary napkin 410, and slits 451, 452 extending in the longitudinal direction Y are formed in both side edge portions of the absorbent body 420. In the first side edge portion 417, the decorative region 440 and the slit 451 overlap each other in a plan view. Since the decorative region 440 overlaps the slit 451, the back surface of the decorative region 440 located on the outer surface of the back sheet 412 is directly visually recognized when viewed from the front surface of the sanitary napkin 410, and therefore the decorative region 440 is visually recognized more clearly, and the outer shape of the absorbent body 420 is difficult to grasp.

In fig. 6, the decorative region 440 of the back sheet 412 can be visually confirmed through the pair of

slits

451 and 452, but the present invention is not limited thereto. For example, the visible elements extending in the longitudinal direction Y and/or the transverse direction X may be disposed on the entire or a part of the absorbent body 420, and the decorative region 440 of the back sheet 412 may be visually recognized from the front side of the sanitary napkin 410, whereby the outer shape of the absorbent body 420 is difficult to grasp. The see-through element may be, for example, a portion of the absorber 420 having a lower quality than other portions, and may be thinned by a compressed concave portion formed by embossing or the like, or may be a portion which is easily seen through by reducing the distance between the decorative region 440 and the topsheet 411, or may be easily seen through by largely changing the hue of the color colored in the decorative region 440 with respect to the hue of the color of the absorber 420.

Fig. 7 is a schematic plan view of another example of a modification of the sanitary napkin. In the present modification, the decorative region 440 is located only at the first end 415 of the first end 415 and the second end 416, and the decorative region 440 and the first end edge 420a of the absorber 420 overlap with each other in a plan view. In this way, since the decorative region 440 is located only at the first end 415 of the sanitary napkin 410, the sanitary napkin 410 has different designs at both ends in the longitudinal direction Y in the back surface side and the front surface side where the decorative region 440 is seen through.

Since the first end edge 420a of the absorber 420 is not clearly visually recognized through the decorative region 440, even when the absorber 420 is displaced in the longitudinal direction Y in the manufacturing process, the displacement can be suppressed from being grasped by the wearer or the like. In addition, since the decorative region 440 is not located at the second end 416 and the shape of the second end edge 420c of the absorber 420 is clearly visually confirmed on the front and back sides, the wearer and the like are not given a feeling of uneasiness due to the absorption and the leakage of bodily fluids to the outside in the longitudinal direction Y.

Here, the phrase "the absorber 420 is positionally shifted in the lateral direction X" means a state in which a longitudinal center line bisecting the dimension of the absorber 420 in the lateral direction X is shifted by less than 10mm toward the first side edge 410c or the second side edge 410d with respect to the longitudinal center line P of the sanitary napkin 410. The positional deviation in the lateral direction X is preferably less than 5mm, and in this case, the decorative region 440 located on the first side edge 410c side can suppress the positional deviation from being grasped by the wearer or the like.

As described above, the decorative region 440 may be disposed so as to overlap the first side edge 420c or the second side edge 420d of the absorbent body 420, or so as to overlap the first end edge 420a or the second end edge 420b, as long as the position of the absorbent body 420 in the longitudinal direction Y or the lateral direction X is controlled so as to improve the appearance of the sanitary napkin 410.

Therefore, in order to suppress the positional deviation of the absorbent body 420 in the longitudinal direction Y or the lateral direction X from being grasped, the decorative region 440 may be disposed only at the first edge portion of the first edge portion and the second edge portion (the first side edge portion 417 and the second side edge portion 418, or the first end portion 415 and the second end portion 416) of the sanitary napkin 410 so as to extend in the first direction (the longitudinal direction Y or the lateral direction X), and may overlap with the first edge (the first side edge 420c or the first end edge 420a) of the absorbent body 420 in a plan view.

As long as the respective components constituting the absorbent article 410 are not particularly described, various known materials generally used in this field can be used without limitation, in addition to the materials described in the present specification. In addition, the terms "first", "second", and "third" used in the present specification and claims are only used for distinguishing the same elements, positions, and the like.

< second to fifth inventions >

The following embodiments of the second to fifth inventions of the present application include not only indispensable structures of the present invention but also optional and preferable structures of the absorbent article shown in the drawings. Hereinafter, an embodiment of a sanitary napkin 10 as an example of an absorbent article of the present invention will be described with reference to the drawings.

Referring to fig. 8 to 10, the package 100 includes a sanitary napkin 10 covered with a packaging sheet 101, and has a longitudinal direction Y, a width direction X, and a thickness direction Z. Each direction X, Y, Z of the package 100 coincides with the longitudinal direction, the width direction, and the thickness direction of the sanitary napkin 10 in the unfolded state shown in fig. 9. Referring to fig. 8, the package 100 includes a first edge 102 and a second edge 103 facing each other in the width direction X, and a third edge 104 and a fourth edge 105 intersecting the first edge 102 and the second edge 103 and extending in the width direction X in a packaged state in which the sanitary napkin 10 is housed.

Referring to fig. 9, the packaging sheet 101 is formed of a thermoplastic synthetic resin fiber nonwoven fabric, a synthetic resin film, or a laminate of a fiber nonwoven fabric and a synthetic resin film. The packaging sheet 101 also has, in an unfolded state, a first end edge 101a and a second end edge 101b of the sheet that oppose each other in the longitudinal direction Y, and both

side edges

101c, 101d of the sheet that oppose each other in the width direction X. When the packaging sheet 101 is made of a nonwoven fabric, it preferably has a mass of 5 to 50g/m². The mass of the packaging sheet 101 made of nonwoven fabric is less than 5g/m²In the case of (2), the sheet becomes relatively thin, so that there is a fear that a part of the packaging sheet 101 is broken at the time of the unfolding operation and the operation is difficult, and on the other hand, the sheet has a mass of 50g/m²In the above case, the thickness becomes relatively thick, and the decorative region 40 serving as an identification means described later disposed in the sanitary napkin 10 may be difficult to visually confirm.

The sanitary napkin 10 has: a length direction Y; a width direction X; a thickness direction Z; a longitudinal center line P bisecting the dimension of the sanitary napkin 10 in the width direction X; and a transverse center line Q bisecting the dimension in the longitudinal direction Y of the sanitary napkin 10. The sanitary napkin 10 includes: a skin-facing surface side and a non-skin-facing surface side opposite thereto; a liquid-permeable top sheet 11 positioned on the skin-facing surface side; a liquid-impermeable back sheet 12 positioned on the non-skin-facing surface side; and a liquid-absorbent body 420 positioned between the topsheet 11 and the backsheet 12.

The sanitary napkin 10 has a substantially cruciform shape, and the outline thereof is defined by a first end edge 10a and a second end edge 10b which are concavely curved inward in the longitudinal direction Y, and a first side edge 10c and a second side edge 10d which are convexly curved outward in the width direction X at a portion intersecting the transverse center line Q.

Although not shown, an intermediate sheet made of a relatively large bulk fiber nonwoven fabric may be disposed between the topsheet 11 and the absorbent member 20 in order to improve the flexibility of the sanitary napkin 10.

The absorbent body 20 has: a first end edge 20a opposite the first end edge 10a and a second end edge 20b opposite the second end edge 10 b; and a first side edge 20c and a second side edge 20d extending in the longitudinal direction between the first end edge 20a and the second end edge 20 b. The topsheet 11 and the backsheet 12 extend outward from the outer periphery of the absorbent body 20, and the pair of side sheets 14 extending in the longitudinal direction Y are arranged on the skin-facing surface side of the topsheet so as to face each other in the width direction X. The pair of side sheets 14 are joined to the surface sheet 11 via side bonding portions.

The sanitary napkin 10 has: a first end portion 15 and a second end portion 16 extending in the width direction X; and a first side edge portion 17 and a second side edge portion 18 extending in the longitudinal direction Y. The first side edge portion 17 and the second side edge portion 18 each have a wing portion 19 projecting outward in the width direction X. The first end edge 20a and the second end edge 20b of the absorber 20 are located at the first end portion 15 and the second end portion 16, respectively, and the first side edge 20c and the second side edge 20d of the absorber 20 are located at the first side edge portion 17 and the second side edge portion 18, respectively. The sanitary napkin 10 further has an outer peripheral edge portion extending from the outer peripheral edge of the absorbent member 20. The sheets stacked on each other to form the outer peripheral edge portion are joined to each other via an outer peripheral seal portion 7 located along the outer peripheral edge of the sanitary napkin 10. It can be said that the peripheral seal portion 7, which thermally welds the sheet, is located at the periphery of the sanitary napkin 10, whereby the outer shape thereof becomes clear and is easily seen through via the packaging sheet 101.

Referring to fig. 12, a plurality of fastening regions 50 are disposed on the back side of the sanitary napkin 10. The plurality of fastening regions 50 are configured to fasten the sanitary napkin 10 to a garment such as underwear, and are formed of a plurality of linear adhesives or pressure-sensitive adhesives extending in the longitudinal direction Y. The fastening region 50 has a central fastening region 51 extending in the longitudinal direction Y in a region overlapping the absorbent body 20, and side fastening regions 52 located at the wing portions 19, and before use, the central fastening region 51 and the side fastening regions 52 are covered with the

separators

28, 29, respectively.

As the top sheet 11, a sheet permeable to liquid components contained in body fluids, such as an open plastic film, woven fabric, or nonwoven fabric, can be preferably used. As the back sheet 12, a thermoplastic resin film mainly composed of a thermoplastic resin such as polyethylene or polypropylene; a thermoplastic resin film to which air permeability is imparted. The side sheet 14 can be made of the same sheet material as the surface sheet 11. However, in order to make it difficult for body fluid to flow to the outside of the sanitary napkin 10, a sheet material having hydrophobic or water-repellent properties is preferably used.

The joining of the respective sheets in the outer peripheral seal portion 7 can be performed by the following joining alone or in combination: adhesive-based bonding; joining by a known welding means such as ultrasonic welding, thermal welding, laser welding, and high-frequency wave welding; and bonding based on imprint processing. The sheets stacked in the thickness direction Z are bonded to each other with an adhesive such as a hot melt adhesive. Examples of the method of applying the hot-melt adhesive include various known coating methods such as spiral coating, curtain coating, and spray coating.

The absorbent body 20 comprises a liquid-absorbent core imparted with a desired shape, and is preferably covered with a core-covering sheet. The liquid-absorbent core has a core composed of water-insoluble superabsorbent polymer particles (SAP particles); an absorbent and dispersible material made of cellulose fibers such as wood pulp (pulp fibers) and rayon fibers. The region between the wings 19 of the absorbent body 20 is a region facing the vaginal opening of the wearer, and the middle-high portion 21 of the absorbent body 20, which is thicker than the other portions, is located in this region.

Referring to fig. 9 and 10, the sanitary napkin 10 has a pair of

longitudinal bending lines

5 and 6 extending by longitudinally cutting the base end portions of the flaps 19, and the sanitary napkin 10 is disposed on the inner surface of the packaging sheet 101 in a state where the flaps 19 are bent inward in the width direction X toward the front surface side along the

longitudinal bending lines

5 and 6. The packaging sheet 101 further has: a first bend line 111 and a second bend line 112 extending in the width direction X; a first region 121 located between second bend line 112 and first end edge 101 a; a second region 122 located between first bend line 111 and second end edge 101 b; and an intermediate region (third region) 123 between the first bend line 111 and the second bend line 112. The pair of

vertical bending lines

5 and 6 may be virtual lines that overlap the base end portions of the wing portions 19, may be virtual lines that are located at opposite positions in the longitudinal direction Y of the wing portions 19 and connect portions that are convexly curved outward in the width direction, or may be virtual lines that change rigidity between the inside and outside in the width direction X according to the number of sheets stacked along the inside edge portions (curved portions in the case of having cuff elastic bodies) of the pair of side sheets 14 fixed to the front surface side of the top sheet 11.

The packaging sheet 101 is laminated in a state in which the sanitary napkin 10 is disposed on the inner surface 100a, the second region 122 is folded along the first folding line 111 toward the inner surface of the intermediate region 123, and then the first region 121 is folded along the second folding line 112 toward the intermediate region 123, and is folded in three. The stacked state is maintained by fixing the fixing tape 130, which is located on the outer surface of the first region 121 of the packaging sheet 101, to the opposing first region 122, thereby forming the individual packages 100. In order to prevent foreign matter or the like from entering the inside of the individual package 100, the first edge portion 102 and the second edge portion 103 are joined by the seal portion 139.

The sanitary napkin 10 has identification means for identifying one side and the other side in the width direction X, which can be visually recognized from the outside through the packaging sheet 101 in a folded state. In the present embodiment, the identification means is constituted by the decorative region 40 disposed on the back sheet 11. The packaging sheet 101 may have the same identification element as the identification means of the sanitary napkin 10, and in the case of the present embodiment, may have a decorative region having the same design as the decorative region 40 of the sanitary napkin 10. The decorative region 40 may be disposed on either the inner surface or the outer surface of the back sheet 12. However, in order to prevent the printed ink from falling off, the decorative region 40 is preferably disposed on the inner surface of the back sheet 12.

The decorative region 40 is formed by a plurality of colored individual decorative portions 41, and at least a part of the decorative region 40 can be visually recognized from the front side and the back side of the sanitary napkin 10, and can be seen through the individual package 100 via the package sheet 101. The decorative region 40 is disposed only on the first side edge 17 of the first side edge 17 and the second side edge 18 of the sanitary napkin 10, and therefore the wearer can recognize the first side edge 17 on which the decorative region 40 is disposed and the second side edge 18 on which the decorative region 40 is not disposed, when viewed from the front and back of the sanitary napkin 10. In this sense, the decorative region 40 can be said to be a recognition means capable of recognizing one side and the other side in the width direction X of the sanitary napkin 10.

The decorative portion 41 is a substantially triangular shape having a large size and a small size, and is disposed independently of each other only at the first side edge 17 of the first side edge 17 and the second side edge 18 of the sanitary napkin 10. The decorative portion 41 has a plurality of arrangement modes such as a mode of arranging at intervals from each other in the longitudinal direction Y and the width direction X, a mode of partially overlapping each other in a plan view, and the like.

The decorative portion 41 may have a shape other than the illustrated shape, such as a substantially circular shape, a substantially oval shape, a substantially rectangular shape, a substantially trapezoidal shape, a substantially star shape, a flower shape, various other well-known decorative patterns, characters (for example, "right and left" character displays), characters, and the like, as long as the technical effects of the present invention described below can be achieved. The decorative portion 41 is colored as a whole, and the colored color may be any color as long as it can be visually recognized clearly from the sheet material and the absorbent core constituting the sanitary napkin, which are colored white by adding a white pigment such as titanium oxide, and for example, a color tone which attracts the attention of the wearer, such as red, blue, yellow, or green, is preferable. In addition, when the back sheet 12 and/or the packaging sheet 101 are colored in a color other than white as a whole, the decorative portion 41 is preferably colored in a color complementary to the colored color.

The "white" in the present application can be exemplified by a color expressed as "N9.5" in the munsell color system and colors expressed as "255, and 255" in the RGB color space, that is, so-called "pure white". In addition, colors of the same system color as "pure white", specifically, colors having a color difference of 0 or more and less than 12 from "pure white" are also included in "white". Colors other than "white" are colored, and cold colors fall into this category. Specifically, a color having a color difference of 40 or more from "white" defined above is preferable. The determination method of white color can be compared with a color difference with respect to white color, and can be determined using, for example, color difference CR-300 manufactured by KONICA MINOLTA (KONICA MINOLTA).

The decorative region 40 constituting the identification means may be disposed not on the outer surface side but on the inner surface side of the back sheet 12, or may be disposed on the surface side or the back side of the top sheet 11, the side sheet 14, the core covering sheet constituting the absorbent body 20, or the like, as long as it can be seen through the packaging sheet 101. The decorative region 40 may be printed directly on each sheet, or may be formed by separately attaching a seal, a patch, or the like.

Referring to fig. 8, the decorative region 40 is disposed only on the first side edge portion 17 of the first side edge portion 17 and the second side edge portion 18 of the sanitary napkin 10, so that the decorative region 40 is seen through the side of the first edge portion 102 folded and overlapped with the first side edge portion 17, and the decorative region 40 is not seen through the side of the second edge portion 103 folded and overlapped with the second side edge portion 18 where the decorative region 40 is not disposed in the single package 100. Therefore, the individual packages 100 have different designs at the first edge 102 side and the second edge 103 side.

In general, an individual package of an absorbent article such as a sanitary napkin has a substantially rectangular shape which is stored in a package sheet in a folded state, and therefore, when it is unfolded, it is difficult to determine in which orientation the sanitary napkin is stored. That is, when the sanitary napkin is unfolded, it is impossible to determine whether the front side of the sanitary napkin is positioned in front of the wearer or the rear side is positioned in front of the wearer. Even when the mode of the sanitary napkin is asymmetrical in the front-rear direction, if the asymmetrical factor is different in the front-rear direction of the length of the fixing region or in the front-rear direction of the mass of the absorber, the difference cannot be easily distinguished at first glance by the wearer.

In the present embodiment, the wearer or the like can easily recognize one side and the other side in the width direction X in the individual package 100 by the individual package 100 having different designs on the first edge 102 side and the second edge 103 side facing each other in the width direction X. Further, since the decorative region 40 constituting the identification means is located only at the first side edge portion 17 of the sanitary napkin 10, the first edge portion 102 side of the individual package 100 is the side where the first side edge portion 17 of the sanitary napkin 10 is located, and as shown in fig. 12, when the packaging sheet 101 is unfolded, it can be easily imagined that the rear side is located near and the front side is located far.

In this way, since the orientation of the sanitary napkin 10 can be grasped via the identification means that is seen through the packaging sheet 101, for example, when a plurality of individual packages 100 are arranged in a vertical or horizontal manner, the first edge portions 102 where the identification means are located can be aligned in the same direction, thereby allowing the wearer to smoothly perform the unfolding operation.

Even if the individual package 100 is used a plurality of times without giving any information on the functional description of the identification means to the wearer, the wearer can grasp that the identification means (the decorative region 40) has a structure having an identification function of informing the orientation of the sanitary napkin, but it is preferable that, for example, a description or a schematic diagram describing the function of the identification means is attached to the outer surface of the storage package in which the plurality of individual packages 100 are stored.

The packaging sheet 101 has a total light transmittance of at least 10%, that is, preferably 10% or more, in order to allow the decorative region 40 to be seen through the packaging sheet 101. When the total light transmittance is less than 10%, the decorative region 40 is difficult to visually recognize and the wearer may not be able to determine the orientation of the sanitary napkin 10. On the other hand, if the total light transmittance of the packaging sheet 101 is assumed to be 100%, the decorative region 40 is easily visually recognized, but the product itself is entirely transparent, and there is a concern that: it is known that an absorbent article such as a sanitary napkin 10 contained in a single package is more sensitive to the pubic sensation. Therefore, the total light transmittance is preferably less than 90%.

The decorative region 40 extends outward in the width direction X than the

longitudinal bending lines

5 and 6 extending in the longitudinal direction Y of the flap 19. Therefore, in a state where the wing portions 19 are bent inward in the width direction X along the

longitudinal bending lines

5, 6, the decorative regions 40 located on the

longitudinal bending lines

5, 6 overlap in the thickness direction Z, and the colored color becomes darker, thereby improving visibility.

In addition, in the outer surface of the back sheet 12, the decorative regions 40 extend outward in the width direction X from both side edges of the

separators

28, 29 covering the fixing regions 50. The

separators

28 and 29 are formed by applying silicone plastic to thick kraft paper, cellophane, plastic film, or the like, and when the entire decorative region 40 is covered with the

separators

28 and 29, visibility may be reduced, and it can be said that the decorative region 40 can be easily seen through from the packaging sheet 101 by at least a portion of the decorative region 40 extending from one edge of the

separators

28 and 29.

Although not shown, the packaging sheet 101 may have a colored decorative region at a position overlapping with the decorative region 40 of the sanitary napkin 10 in the individual package 100. In this case, the decorative region 40 and at least a part of the decorative region of the packaging sheet 101 are overlapped with each other to improve visibility, and thus, the individual package 100 and the sanitary napkin 10 can be more easily distinguished from each other in the width direction X.

< second embodiment >

Fig. 13 is the same view as fig. 12 of the individual package 100 of the second embodiment. Referring to fig. 13, in the sanitary napkin 10 of the individual package 100 of the present embodiment, the first side edge 10c is a linear shape without undulation formed by combining linear portions, whereas the second side edge 10d has an undulating linear shape including a plurality of narrowed portions. The first side edge 10c and the second side edge 10d of the sanitary napkin can be seen through from the packaging sheet 101. Therefore, in the state of being folded and stored in the individual package 100, the individual package 100 has different designs on the first edge portion 102 side where the first side edge 10c is located and on the second edge portion 103 side where the second edge portion 10d is located, and the wearer can easily recognize one side and the other side in the width direction X of the individual package 100 and the sanitary napkin.

< third embodiment >

Fig. 14 (a) is a perspective view similar to fig. 8 of the individual package 100 of the third embodiment. In the present embodiment, the first decorative region 141 is disposed on the first side edge portion 17 and the second decorative region 142 is disposed on the second side edge portion 18 of the sanitary napkin 10. The decorative portions 41 are arranged relatively densely in the first decorative region 141 of the first side edge portion 17, and the decorative portions 41 are arranged relatively sparsely in the second decorative region 142 of the second side edge portion 18. Therefore, the total area of the first decorative regions 141 at the first side edge portion 17 and the total area of the second decorative regions 142 at the second side edge portion 18 are different from each other.

In this way, the total area of the first decorative region 141 located at the first side edge portion 17 of the sanitary napkin 10 and the total area of the second decorative region 142 located at the second side edge portion 18 are different from each other, and are seen through via the packaging sheet 101, whereby the wearer and the like can easily recognize one side and the other side in the width direction X of the individually packaged body 100 and the sanitary napkin 10.

< fourth embodiment >

Fig. 14 (b) is a perspective view similar to fig. 8 of the fourth embodiment. Referring to fig. 14 (b), the dressing region 40 of the sanitary napkin 10 is disposed only in the region between the transverse center line Q and the first end edge 10a side of the first side edge portion 17. In this case, in the first edge portion 102 of the individual package 100, the decorative region 40 is not located on the fourth edge portion 105 side. By further limiting the arrangement region of the decorative region 40 in this manner, the wearer can recognize not only the orientation in the width direction X but also the orientation in the longitudinal direction Y of the sanitary napkin 10.

In this embodiment, the decorative region 40 is not disposed in a region between the transverse center line Q and the second end edge 10b side in the first side edge portion 17. The wearer or the like can visually confirm that the decorative region is not disposed on the second edge 10b side, and can recognize not only the orientation in the width direction X but also the orientation in the longitudinal direction Y of the sanitary napkin 10. In particular, when the packaging sheet 101 itself has a plurality of decorative elements, it can be said that the wearer can visually recognize the orientation in the longitudinal direction Y more than when the decorative region 40 is present only on the first end edge 10a side and when the decorative region 40 is not present only on the second end edge 10b side.

< fifth embodiment >

Fig. 15 (a) is a plan view of the sanitary napkin 10 according to the fifth embodiment, and fig. 15 (b) is a perspective view of the individual package 100 according to the fifth embodiment. Referring to fig. 15 (a), a decorative region 40 forming an identification means is disposed only on the first end portion 15 side on the inner surface (or the outer surface) of the back sheet 11 of the sanitary napkin 10. That is, the decorative region 40 is not disposed on the first side edge portion 17, the second side edge portion 18, and the second end portion 16 of the sanitary napkin 10.

Referring to fig. 15 (b), in this embodiment, in a state where the sanitary napkin is folded into three and stored in the individual package 100, the decorative region 40 disposed at the first end portion 15 is positioned on the fourth edge portion 105 side in the longitudinal direction Y of the individual package 100. Therefore, the decorative region 40 is seen through from the packaging sheet 101 at the fourth edge portion 105 side, whereby the wearer or the like can recognize the orientations of the individual packages 100 and the sanitary napkin 10 in the longitudinal direction Y. In addition, as long as the wearer can recognize the longitudinal direction Y of the individual package 100 and the sanitary napkin 10, the decorative region 40 may be disposed in a region between the transverse center line Q and the first end edge 10a (or the second end edge 10b) and in a region between the transverse center line Q and the second end edge 10b (or the first end edge 10a) of the sanitary napkin 10.

Fig. 16 (a) is a plan view of the sanitary napkin 10 according to the sixth embodiment, and fig. 16 (b) is a perspective view of the individual package 100 according to the sixth embodiment. Referring to fig. 16 (a), in the back sheet 11 of the sanitary napkin 10, the decorative region 40 formed by the plurality of decorative portions 41 extends in the longitudinal direction Y so as to cross the first bending line 111. Specifically, the decorative portions 41 forming the decorative region 40 intersect the first bending line 111, and are located on the first end edge 10a side and the second end edge 10b side with respect to the first bending line 111. In addition, at the portion of the first bending line 111 on the first edge 10a side, the decorative region 40 is located between the transverse center line Q and the first bending line 111, and is not located on the first edge 10a side (or the second bending line 112 side) with respect to the transverse center line Q.

Referring to fig. 16 (b), in a state where the sanitary napkin 10 is contained in the packaging sheet 101 in a state of being folded in three along the first folding line 111 and the second folding line 112, the decorative region 40 is located on the fourth edge portion 105 side of the individual package 100. Therefore, in a state where the sanitary napkin 10 is folded and stored in the packaging sheet 101, the decorative region 40 is a recognition means for recognizing one side (the first edge 10a side) and the other side (the second edge 10b side) in the longitudinal direction Y of the sanitary napkin 10, and is also a recognition means for recognizing one side (the third edge 104 side) and the other side (the fourth edge 105 side) in the longitudinal direction Y of the individual package 100. The portion of the individual package 100 on the fourth edge 105 side where the decorative region 40 of the sanitary napkin 10 is located overlaps, and thus the coloring becomes deeper and the visibility from the outside becomes easier.

In the present embodiment, the decorative region 40 formed by the plurality of decorative portions 41 extends in the longitudinal direction Y so as to straddle the first bending line 111, but the decorative region 40 may extend in the longitudinal direction Y so as to straddle the second bending line 112 without straddling the first bending line 111. In this case, the decorative portions 41 forming the decorative region 40 intersect the second bending line 112 and are located at a position closer to the first end edge 10a or the second end edge 10b than the second bending line 112. In addition, the decorative region 40 is located between the transverse center line Q and the second bending line 112, and is not located on the second end edge 10b side (or the first bending line 111 side) with respect to the transverse center line Q, at a portion on the second end edge 10b side with respect to the second bending line 112.

< Assembly of multiple individually packaged bodies >

Fig. 17 (a) is a perspective view of an assembly 200 formed of a plurality of individual packages (first to third individual packages 100A to 100C), and fig. 17 (b) is a perspective view of the assembly 200 in an example of the embodiment. As shown in the drawing, the assembly 200 may have at least two of the three types of individual packages 100A to 100C, and may have four or more types of individual packages as long as the technical effects described below can be achieved.

Referring to fig. 17 (a), the assembly 200 is formed by vertically arranging a plurality of first individual packages 100A to third individual packages 100C in a vertical direction with the width direction X of the first individual packages 100A to the third individual packages 100C as the vertical direction, and the first individual packages 100A to the third individual packages 100C have substantially equal outer dimensions. The decorative elements of the

decorative regions

181, 182, and 183 constituting the identification means of the sanitary napkin 10 housed in the first individual package 100A to the third individual package 100C are different from each other. Specifically, the decorative region 181 of the first individual package 100A is formed by a plurality of triangular patterns, the decorative region 182 of the second individual package 100B is formed by a plurality of dot patterns, and the decorative region 183 of the third individual package 100C is formed by a plurality of star patterns. Here, the fact that the outer dimensions of the first individual package 100A to the third individual package 100C are substantially equal means that the difference in the outer dimensions is within 10 mm.

As described above, even when the outer dimensions of the first individual package 100A to the third individual package 100C are substantially equal, the decorative elements of the decorative regions 181 to 183 are different from each other, and thus the wearer or the like can recognize the first individual package 100A to the third individual package 100C instantaneously and can recognize the orientation of the absorbent article 10 stored therein instantaneously. Therefore, for example, even if the outer dimensions of the first individual packages 100A to the third individual packages 100C are substantially the same, the use applications of the first individual packages 100A to the third individual packages 100C can be easily grasped and identified by changing the decorative elements in conjunction with the use applications such as daily use and night use. The decorative regions 181 to 183 have not only different shapes of the plurality of decorative portions constituting them, but also different colors of the decorative portions, which have the same, similar, or dissimilar shapes. Even if the decorative regions 181 to 183 or the plurality of decorative portions constituting them have the same shape, the decorative regions can be visually recognized by coloring the decorative regions in different colors.

Referring to fig. 17 (b), in the present embodiment, the first individual package 100A to the third individual package 100C have different outer dimensions. The first individual package 100A is an individual package containing a sanitary napkin for night use, for example, which is used for a relatively long time, the second individual package 100B is an individual package containing a sanitary napkin for daily use, for example, and the third individual package 100C is an individual package containing a light and thin sanitary napkin or a sanitary pad, for example. The decorative elements of the

decorative regions

181, 182, and 183 constituting the identification means of the sanitary napkin 10 housed in the first individual package 100A to the third individual package 100C are different from each other. Specifically, the decorative region 181 of the first individual package 100A is formed by a plurality of triangular patterns, the decorative region 182 of the second individual package 100B is formed by a plurality of dot patterns, and the decorative region 183 of the third individual package 100C is formed by a plurality of star patterns.

As described above, the first individual package 100A to the third individual package 100C having various sizes and different sizes have the different decorative regions 181 to 183, respectively, so that the wearer and the like can grasp and recognize the use and the like of the first individual package 100A to the third individual package 100C more reliably by the difference in the decorative elements of the decorative regions 181 to 183 in accordance with the difference in the sizes. In addition, the decorative elements of the decorative regions 181-183 are preferably the same pattern but different colors. Since the patterns are the same, for example, even when a daily product and a night product having the same size are purchased and stored together, they can be recognized by the difference in color.
