Description

  The present invention relates to an absorbent article package.

  Absorbent article packages that are individually wrapped with a packaging material (packaging sheet) in a state where absorbent articles such as sanitary napkins and incontinence pads are folded are known. In such an absorbent article package, it is common to use a method in which the packaging material is removed from the absorbent article during use, and the absorbent article is wrapped in the packaging material after use and discarded. For example, Patent Document 1 discloses an absorbent article by providing a display portion at a predetermined position of a packaging material (packaging sheet) and clarifying a reference position where the packaging material should be folded when the absorbent article after use is wrapped. An absorbent article package capable of easily wrapping is disclosed.

JP 2009-178275 A

Many users (users) of absorbent articles have a desire not to let another person's eyes touch the absorbent article to which menstrual blood or the like has adhered when the absorbent article after use is discarded. For example, adolescent middle and high school users often use the same toilet with friends at school, etc., so there is a strong desire to discard the napkin after use. However, in the conventional absorbent article package, even if it is wrapped with a packaging material after use, menstrual blood, etc. attached to the absorbent article can be seen from the outside through the packaging material, so that the menstrual blood is sufficiently concealed. I couldn't.
The present invention has been made in view of the problems as described above, and the object of the present invention is to sufficiently conceal menstrual blood and the like adhering to the absorbent article after use with a packaging material. The object is to provide an absorbent article package.

A main invention for achieving the above object is a sanitary napkin, a panty liner, or an absorbent pad, the absorbent article having a front-rear direction, and a packaging material for packaging the absorbent article. A packaging body comprising: a first animal design in which more than half of the region is colored in black; a first animal design adjacent to the first animal design in a predetermined direction; and more than half of the region is colored in black. A maximum diffusion region that is the maximum region in which the liquid diffuses when 4.5 ml of liquid is dropped onto the absorbent article and left for 10 minutes. When the packaging material is overlapped on the skin side and viewed from the non-skin side, the pitch between the first animal design and the second animal design in the longitudinal direction of the packaging material is the maximum diffusion region in the longitudinal direction. Shorter than the length, and Satisfying at least one of the conditions in which the pitch between the first animal symbol and the second animal symbol in the width direction of the dressing is shorter than the length of the maximum diffusion region in the width direction, the first animal The absorbent article packaging body is characterized in that the area of each of the design and the second animal design is smaller than the area of the maximum diffusion region.
Other features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

  ADVANTAGE OF THE INVENTION According to this invention, the absorbent article packaging body which can fully conceal the menstrual blood etc. which adhered to the absorbent article after use with a packaging material can be provided.

It is a schematic perspective view which shows the napkin 1 (packaging body 10) of a packaging state. It is a schematic plan view when the package 10 in the unfolded state is viewed from the skin side. It is a schematic plan view when the package 10 in the unfolded state is viewed from the non-skin side. It is a schematic sectional drawing showing an example of the state at the time of discarding the napkin 1. FIG. FIG. 6 is a diagram illustrating a state in which a menstrual blood maximum diffusion region DR is concealed by an animal symbol 20. 6A and 6B are diagrams illustrating a state when the napkin 1 is discarded by a method different from that in FIG. It is a top view shown about the case where the stripe pattern 25 is provided in the packaging material 11. FIG.

At least the following matters will become apparent from the description of the present specification and the accompanying drawings.
A sanitary napkin, a panty liner, or an absorbent pad, comprising an absorbent article having a front-rear direction and a packaging material for packaging the absorbent article, wherein the packaging material comprises: A first animal design in which more than half of the region is colored in black and a second animal design that is adjacent to the first animal design in a predetermined direction and in which more than half of the region is colored in black; 4.5 ml of liquid is dropped onto the absorbent article and the maximum diffusion area, which is the maximum area where the liquid diffuses when left for 10 minutes, is placed on the non-skin side of the absorbent article by overlapping the packaging material. When viewed from the skin side, the pitch of the first animal design and the second animal design in the longitudinal direction of the packaging material is shorter than the length of the maximum diffusion region in the longitudinal direction; The first animal pattern in the width direction Satisfying at least one of the conditions that the pitch with the second animal symbol is shorter than the length of the maximum diffusion region in the width direction, and the area of each of the first animal symbol and the second animal symbol is The absorbent article packaging body is smaller than the area of the maximum diffusion region.

  According to such an absorbent article package, when the napkin (absorbent article) is discarded after use, when the napkin is wrapped with the packaging material, menstrual blood, etc. attached to the napkin overlaps with the black animal pattern. It becomes difficult to see from the outside by being concealed. In addition, the animal's image works strongly psychologically, making it difficult for the viewer to focus on menstrual blood. Therefore, menstrual blood and the like can be sufficiently concealed.

  In such an absorbent article package, it is desirable that a plurality of the animal designs are arranged side by side along the longitudinal direction of the absorbent article.

  According to such an absorbent article packaging body, it is possible to increase the probability that the maximum diffusion region of menstrual blood that tends to spread in the longitudinal direction overlaps with the animal design. This makes it easier to conceal menstrual blood more effectively.

  In such an absorbent article package, it is desirable that a plurality of the animal designs are arranged at an equal pitch in the longitudinal direction.

  According to such an absorbent article package, when the napkin (absorbent article) after use is discarded, when the napkin is wrapped with the packaging material, among the plurality of animal patterns arranged along the longitudinal direction Any of them becomes more likely to overlap with the maximum diffusion region of menstrual blood in the longitudinal direction, and menstrual blood is more easily concealed.

  In such an absorbent article package, it is desirable that a plurality of the animal designs are arranged side by side at an equal pitch along the width direction intersecting the longitudinal direction of the absorbent article.

  According to such an absorbent article package, when the napkin (absorbent article) after use is discarded, when the napkin is wrapped with the packaging material, among the plurality of animal designs arranged along the width direction Any of them becomes more likely to overlap with the maximum diffusion region of menstrual blood in the width direction, and menstrual blood is more easily concealed. In addition, even when the napkin and the packaging material are overlapped so that their longitudinal directions cross each other, there is a high possibility that the animal pattern and the maximum menstrual diffusion region overlap, concealing menstrual blood. It becomes easy.

  In such an absorbent article package, it is desirable that a plurality of the animal designs are arranged in a staggered manner.

  According to such an absorbent article packaging body, when disposing the packaging material around the outer side of the absorbent article, the animal design arranged in the first layer of the packaging material and the thickness of the first layer The position of the animal symbol arranged in the second layer stacked in the vertical direction is likely to shift. Accordingly, when viewed from the outside, the proportion of the area of the animal symbol occupying the surface of the packaging material is apparently increased, and the probability that the maximum diffusion region of menstrual blood and the animal symbol overlap is increased. This makes it easier for the menstrual blood diffusion area to be concealed by animal designs.

  In such an absorbent article package, the absorbent article has a non-skin side sheet on the non-skin side, and the color of the non-skin side sheet and the color of the packaging material are similar colors. It is desirable.

  According to such an absorbent article packaging body, when the non-skin side sheet of the absorbent article and the packaging material are overlapped in the thickness direction, both have a similar color relationship. A black animal design is easily visually recognized on any of the skin-side sheets, and the effect of concealing menstrual blood by the animal design is easily maintained.

  In such an absorbent article package, the absorbent article has a non-skin side sheet on the non-skin side, and the color of the non-skin side sheet and the color of the packaging material are opposite colors. It is desirable.

  According to such an absorbent article packaging body, when the non-skin-side sheet of the absorbent article and the packaging material are overlapped in the thickness direction, the overlapped portion of the absorbent article appears to be dark as a whole. Therefore, menstrual blood itself becomes difficult to be visually recognized in the part where both are overlapped.

  In such an absorbent article package, it is desirable that the length of the animal design is smaller than ¼ of the length of the absorbent article in the longitudinal direction of the absorbent article.

  According to such an absorbent article packaging body, even when the napkin is folded in four in the longitudinal direction, the possibility that the entire animal design is visually recognized on the surface of the packaging material is increased. Therefore, the viewer's attention is more easily directed to the animal pattern than menstrual blood, and menstrual blood can be made inconspicuous.

  In such an absorbent article packaging body, it is desirable that the packaging material is provided with a plurality of strip-shaped stripe portions along a predetermined direction at intervals in a direction intersecting the predetermined direction.

  According to such an absorbent article packaging body, at least a part of the stripe portion overlaps with the maximum menstrual diffusion region, the maximum diffusion region appears to be divided by the stripe portion, and the entire shape is difficult to recognize. Become. This makes menstrual blood less noticeable. In addition, the design of the stripe part enhances the impression of the animal design, making it easier to concentrate the viewer's attention from menstrual blood to the animal design.

  In such an absorbent article package, it is desirable that the stripe portion has a red color.

  According to such an absorbent article package, since the color of menstrual blood visually recognized from the non-skin side of the napkin (absorbent article) is dark red, by forming the stripe portion with red of a similar color, When overlapping with the maximum diffusion region of menstrual blood, it is possible to make it difficult to recognize the shape of the maximum diffusion region.

  In such an absorbent article package, it is desirable that the packaging material is a hydrophobic sheet member.

  According to such an absorbent article package, when the napkin (absorbent article) after use is discarded, when the napkin is wrapped with the packaging material, menstrual blood oozes from the skin side of the packaging material to the non-skin side. It is possible to prevent menstrual blood that should be concealed from being easily visible from the outside or soiling the user's hand.

  In this absorbent article package, it is preferable that the animal design is printed on the skin side surface of the packaging material with hydrophobic ink.

  According to such an absorbent article package, when the napkin after use (absorbent article) is discarded, when the napkin is wrapped with the packaging material, menstrual blood is easily repelled on the skin side of the packaging material. It is possible to prevent menstrual blood from spreading on the non-skin side of the packaging material and to make it easier to conceal menstrual blood.

=== First Embodiment ===
Hereinafter, as an example of the absorbent article package according to the present invention, an absorbent article package 10 (hereinafter also simply referred to as “package 10”) of a sanitary napkin 1 (hereinafter also simply referred to as “napkin 1”) is taken as an example. Embodiments are described below. The absorbent article is not limited to a sanitary napkin, and may be an absorbent article used by being fixed to a user's clothes, such as a panty liner or an absorbent pad.
<Basic structure of absorbent article packaging>

  FIG. 1 is a schematic perspective view showing the napkin 1 (package 10) in a packaged state. FIG. 2 is a schematic plan view when the package 10 in a developed state is viewed from the skin side. FIG. 3 is a schematic plan view when the package 10 in a developed state is viewed from the non-skin side.

  The napkin 1 (packaging body 10) has a longitudinal direction, a width direction, and a thickness direction orthogonal to each other. Further, in the longitudinal direction of the napkin 1, the side that contacts the user's lower abdomen is referred to as "front side", and the side that contacts the user's buttocks is referred to as "rear side". Further, in the thickness direction of the napkin 1, the side that contacts the user's skin is referred to as "skin side", and the opposite side is referred to as "non-skin side".

  The packaging body 10 includes the folded napkin 1 and the packaging material 11, and the packaging material 11, the protective sheet 15, and the napkin 1 are arranged so as to overlap from the non-skin side in the thickness direction in the unfolded state of FIGS. 2 and 3. Has been. The protective sheet 15 is a sheet member for protecting the central adhesive portion 6 (described later) of the napkin 1, and its non-skin side surface is joined to the packaging material 11. On the other hand, the skin side surface of the protective sheet 15 is subjected to a peeling process using silicon resin or the like, and the central adhesive portion 6 is detachably attached to the skin side surface of the protective sheet 15.

The unfolded packaging body 10 (napkin 1, packaging material 11) is formed in a state in which a wing 1W (described later) is folded inward in the width direction, and then the skin side of the napkin 1 is disposed inside. The second folding part F2 along the width direction and the first folding part F1 are sequentially folded in the longitudinal direction, the end part in the width direction is subjected to a process such as heat fusion, and the longitudinal end of the packaging material 11 By locking the part with the tape 12, the package 10 in the packaged state shown in FIG. 1 is obtained.
<< Napkin 1 >>

  The napkin 1 has a pair of wing portions 1W extending from the center in the longitudinal direction to both outer sides in the width direction. Hereinafter, in the longitudinal direction of the napkin 1, a portion where the wing portion 1W is provided is referred to as a central portion 1B, a portion on the front side from the central portion 1B is referred to as a front side portion 1A, and a portion on the rear side from the central portion 1B is referred to as a rear side portion 1C.

  In the napkin 1, a skin side sheet 2, an absorbent body 4, and a non-skin side sheet 3 are laminated in order from the skin side in the thickness direction, and bonded with an adhesive or the like.

  The skin-side sheet 2 is a liquid-permeable sheet member, and examples thereof include an air-through nonwoven fabric. The non-skin-side sheet 3 is a liquid-impermeable sheet member, and examples thereof include a polyethylene (PE) resin film. The skin side sheet 2 and the non-skin side sheet 3 have a larger planar size than the absorbent body 4 and cover the entire planar surface of the absorbent body 4.

  The absorber 4 is a member that absorbs excrement and holds it inside. The absorbent body 4 is composed of a liquid absorbent fiber such as pulp fiber or a liquid absorbent fiber containing a highly absorbent polymer (so-called SAP).

  The absorber 4 has a pressing part 5. The pressing part 5 is formed from a plurality of circular pressing parts. As shown in FIG. 2, when the pressing part 5 is visually recognized from the skin side surface, it represents the design of a cat. Specifically, the front side 1A represents the head of the cat, the center 1B represents the torso of the cat, and the rear side 1C represents the leg and tail of the cat.

  A central adhesive portion 6 is provided on the non-skin side surface of the napkin 1 (that is, the non-skin side surface of the non-skin side sheet 3) (see FIG. 3). The central adhesive portion 6 is provided in the central portion 1B in the longitudinal direction, a region extending the central portion 1B to the front side and the rear side, and the central region in the width direction. The central adhesive portion 6 is detachably attached to the packaging material 11 via the protective sheet 15 before the napkin 1 is used. And at the time of use of the napkin 1, it peels off from the packaging material 11 (protection sheet 15), and is affixed on the skin side surface of clothes, such as underwear. Thereby, the napkin 1 is fixed to underwear or the like.

  Similarly, the wing adhesion part 7 is provided in the non-skin side surface of the thickness direction of the wing part 1W. When the napkin 1 is used, the wing portion 1W is bent to the non-skin side, and the wing adhesive portion 7 is attached to the non-skin side surface such as underwear. Thereby, wing part 1W is fixed to underwear etc.

<< Packaging Material 11 >>
The packaging material 11 is a sheet member for individually packaging the napkin 1, and is formed from various films such as a film obtained by laminating a nonwoven fabric, a plastic film, and a nylon film. The packaging material 11 is joined in a state of being overlapped on the non-skin side in the thickness direction of the napkin 1 with the protective sheet 15 interposed therebetween, and together with the napkin 1, the second folding portion F2 and the first folding portion F1. Then, the napkin 1 is wrapped so as to be wrapped inside, and the package 10 is formed.

  The packaging material 11 of the present embodiment is provided with a plurality of animal symbols 20. The animal pattern 20 is printed on the skin side surface (or non-skin side surface) of the packaging material 11 using hydrophobic black ink or the like. The user of the napkin 1 can visually recognize the animal symbol 20 from the outside of the package 10 in the packaging state of FIG. 1 (on the non-skin side in the developed state of FIG. 3). Details of the animal symbol 20 will be described later.

<About the usage mode of the napkin 1>
Then, the general usage aspect of the napkin 1 (packaging body 10) is demonstrated easily.
The napkin 1 is distributed in the market in a packaging state (packaging body 10) as shown in FIG. The user who has obtained the package 10 first releases the locking of the tape 12 and develops the package 10 as shown in FIGS. Then, the packaging material 11 (and the protective sheet 15) is peeled off from the non-skin side of the napkin 1 to expose the adhesive surfaces of the central adhesive portion 6 and the wing adhesive portion 7, and the napkin 1 is put on the underwear by the adhesive portions 6 and 7. Use fixed (wear). At this time, the user does not discard the removed package 10 but stores it in a bag or the like.

  After the napkin 1 is used, the adhesive portions 6 and 7 are peeled off from the underwear, the napkin 1 is removed, and discarded in a trash can. When the user discards the napkin 1, it is general that the napkin 1 is rolled and folded so that the outside of the napkin 1 is wrapped in the package 10 and then discarded. This is because menstrual blood or the like adheres to the napkin 1 after use, so that the menstrual blood is concealed by wrapping the napkin 1 with the package 10 so that it is difficult to touch others.

  FIG. 4 is a schematic cross-sectional view showing an example of a state when the napkin 1 is discarded. In the example of FIG. 4, in a state where the napkin 1 after use is overlapped with the packaging material 11, the packaging material 11 is rolled up in the longitudinal direction so as to be on the outside, and the longitudinal end portion of the packaging material 11 is covered with the tape 12. It is fixed. In this way, the user can discard the used napkin 1 in a compact shape without exposing it to the outside.

  However, since the packaging material 11 is formed of a film or the like and has a certain degree of light transmittance, menstrual blood adhering to the internal napkin 1 is seen from the outside of the packaging material 11 in the state of FIG. May appear. That is, there is a possibility that menstrual blood cannot be sufficiently concealed.

  Therefore, in the present embodiment, by providing the predetermined animal design 20 on the packaging material 11, it is possible to sufficiently conceal menstrual blood and the like attached to the napkin 1 by the animal design 20 when the napkin 1 is overlaid. I am doing so. Hereinafter, the detail of the animal symbol 20 provided in the packaging material 11 of the napkin 1 of this embodiment is demonstrated.

<Details of animal design 20>
First, a “menstrual blood” diffusion region to be concealed by the animal symbol 20 is defined. Since the menstrual blood diffusion region varies depending on individual differences and usage conditions, the following experiment is performed in advance, and the maximum region in which menstrual blood diffuses in the normal usage mode of the napkin 1 is defined as the “maximum diffusion region”.

  In the experiment, first, a liquid (for example, artificial menstrual blood) is dropped at the center of the skin side surface of the napkin 1 at a rate of 4.5 ml for 10 seconds, that is, 27 ml / min, and left for 30 seconds. The dripping amount (4.5 ml) of artificial menstrual blood was determined from the average absorbed amount of menstrual blood when a trial test of the napkin 1 was conducted with a plurality of women assumed as users of the napkin 1 as testers. Amount. In this experiment, the liquid (artificial menstrual blood) dropped on the napkin 1 is, for example, 80 g of glycerin, 8 g of sodium carboxymethylcellulose, 10 g of sodium chloride, 4 g of sodium bicarbonate, 8 g of red No. 102 for 1 L of ion-exchanged water. 2 g of red No. 2 and 2 g of yellow No. 5 were added and sufficiently stirred. A value obtained by measuring the viscosity of the liquid (artificial blood) with a viscosity measuring device (Bismetron type VGA-4 manufactured by Shibaura System Co., Ltd.) is about 22 to 26 mPa · s.

  Next, a weight is placed on the portion where the artificial menstrual blood has been dropped and left for 10 minutes under a pressure of 30 g / cm 2. This pressure (30 g / cm 2) is a value that assumes the pressure applied to the central portion of the napkin 1 when the napkin 1 is worn. Then, after standing for 10 minutes, the length in the longitudinal direction is measured with the region where the artificial menstrual blood is diffusing on the non-skin side surface of the napkin 1 as the maximum diffusion region DR. This experiment is performed 10 times, and the average value is defined as the length Ldr in the longitudinal direction of the maximum diffusion region DR. Similarly, the length in the width direction of the maximum diffusion region DR is also measured 10 times, and the average value is set as the length Wdr in the width direction of the maximum diffusion region DR.

  When the napkin 1 is discarded, the napkin 1 is mostly rounded or folded so that the side of the skin that absorbs menstrual blood is on the inside. Menstrual blood will be visually recognized on the side. That is, menstrual blood diffused on the non-skin side surface of the napkin 1 is a concealment target. Therefore, in the above-described experiment, the “maximum diffusion region” of menstrual blood on the non-skin side surface of the napkin 1 is measured.

  As a result of the measurement, the length Ldr in the longitudinal direction of the maximum diffusion region DR was 44 mm, and the length in the width direction was Wdr = 27 mm. In the napkin 1, menstrual blood is easily diffused in the longitudinal direction according to the user's vaginal opening. Therefore, the length Ldr in the longitudinal direction of the maximum diffusion region DR is longer than the length Wdr in the width direction. It has become.

  FIG. 5 is a diagram illustrating a state in which the menstrual blood maximum diffusion region DR is concealed by the animal symbol 20. FIG. 5 shows the napkin 1 in the unfolded state as viewed from the non-skin side, as in FIG. 3, and corresponds to the state in which the napkin 1 and the packaging material 11 in FIG. 4 are expanded. Further, in FIG. 5, the portion indicated by sand represents the maximum diffusion region DR.

  In the packaging material 11 of the present embodiment, a plurality of animal symbols 20, 20,... Are arranged side by side at a predetermined pitch in the longitudinal direction and the width direction. The animal symbol 20 represents an animal silhouette, and more than half of the region is colored “black”. FIG. 5 shows an animal symbol 20 in which a black cat with a ribbon attached to the neck is sitting. And parts other than the ribbon are colored in black. Note that “black” here does not need to be black in a strict sense, and if the user can visually recognize a color close to black, other colors such as dark gray, brown, brown, etc. Colors may be mixed. For example, in the RGB color system, (0, 0, 0) is not necessarily required, and (0, 0, 10) may be used. Furthermore, the “black” forming the animal symbol 20 may be black enough to conceal menstrual blood when the packaging material 11 is stacked on the non-skin side of the napkin 1 after use. In the present embodiment, as shown in FIG. 5, the animal pattern 20 is formed in a darker color (black) than the maximum menstrual diffusion region DR, so that the outer shape of the maximum diffusion region DR is difficult to recognize. The menstrual blood can be made inconspicuous.

  In addition, the animal symbol 20 is not a simple geometric pattern such as a star shape or a heart shape, but is an animal symbol, so that a person who has seen the animal symbol 20 has a cute image of an animal (a cat in FIG. 5). It is easy to recall. Furthermore, it is confirmed that people who look at the pose and facial expression may have some feeling in the pattern, and when used for sanitary napkins, liners, etc., it is more noticeable than the geometric pattern Has been. That is, the image of an animal acts more psychologically than the image of menstrual blood, which makes it difficult for the viewer to pay attention to menstrual blood. Therefore, the effect of concealing menstrual blood by the animal design 20 is increased. The animal symbol 20 may be an animal other than a cat or may take a different pose.

  As shown in FIG. 5, the area S20 of each animal symbol 20 is smaller than the area Sdr of the maximum diffusion region DR. If the area S20 of the animal symbol 20 is larger than the area Sdr of the maximum diffusion region DR, there is a possibility that the animal symbol 20 is formed by the diffusion of menstrual blood. That is, when viewed from the non-skin side of the packaging material 11, a black pattern having a large area is easily noticeable, and at first glance, the animal symbol 20 itself may appear to be a spread of menstrual blood. On the other hand, in this embodiment, by making the area S20 of the animal symbol 20 smaller than the area Sdr of the maximum diffusion region DR, it is difficult to cause a misunderstanding that each animal symbol 20 is menstrual blood.

  Further, the pitch in the longitudinal direction of the two adjacent animal symbols 20 and 20 is shorter than the length Ldr in the longitudinal direction of the maximum diffusion region DR, and the pitch in the width direction of the two adjacent animal symbols 20 and 20 is maximum. Each animal symbol 20 is arranged so as to satisfy at least one of the conditions that it is shorter than the length Wdr in the width direction of the diffusion region DR. In FIG. 5, the pitch P1 in the longitudinal direction of the animal symbol 20A (first animal symbol) and the animal symbol 20B (second animal symbol) adjacent to the animal symbol 20A obliquely below is the longitudinal direction of the maximum diffusion region DR. It is shorter than the length Ldr. Similarly, the pitch P2 in the width direction between the animal symbol 20A and the animal symbol 20B is shorter than the length Wdr in the width direction of the maximum diffusion region DR. If it is such a relationship, possibility that at least one will overlap with the largest spreading | diffusion area | region DR among the animal designs 20A and the animal designs 20B arrange | positioned adjacently will become high. Therefore, the probability that menstrual blood is concealed by the animal symbol 20 can be increased.

  In FIG. 5, the pitch (= 0) in the width direction between the animal symbol 20A and the animal symbol 20C adjacent in the longitudinal direction of the animal symbol 20A is shorter than the length Wdr in the width direction of the maximum diffusion region DR. . Further, the pitch (= 0) in the longitudinal direction between the animal symbol 20A and the animal symbol 20D adjacent in the width direction of the animal symbol 20A is shorter than the length Ldr in the longitudinal direction of the maximum diffusion region DR. Therefore, in any case, the above-described conditions are satisfied, and in the packaging material 11 of the present embodiment, the menstrual blood (maximum diffusion region DR) can be efficiently concealed by the animal design 20.

  Incidentally, in the maximum diffusion region DR, as described above, the length Ldr in the longitudinal direction tends to be longer than the length Wdr in the width direction. That is, the napkin 1 makes it easy to diffuse menstrual blood in the longitudinal direction. In contrast, in the packaging material 11 of the present embodiment, at least two animal symbols 20 and 20 (for example, animal symbols 20A and 20C in FIG. 5) are arranged side by side in the longitudinal direction. The probability that the expanded menstrual blood (maximum diffusion region DR) and the animal symbol 20 overlap can be increased. This makes it easier to conceal menstrual blood that has spread in the longitudinal direction.

  Further, in the packaging material 11 of the present embodiment, the animal symbols 20, 20,... Adjacent in the longitudinal direction are arranged at an equal pitch. That is, in the packaging material 11, the animal symbols 20 are regularly arranged along the longitudinal direction. Therefore, when the napkin 1 is discarded, when the napkin 1 and the packaging material 11 are overlapped, any one of the plurality of animal symbols 20 arranged along the longitudinal direction does not depend on the overlapped position. The possibility of overlapping with the maximum diffusion region DR is higher, and menstrual blood is easily concealed.

  Similarly, in the packaging material 11 of this embodiment, the animal symbols 20 and 20 (for example, the animal symbols 20A and 20D in FIG. 5) are arranged side by side in at least the width direction, and the animal symbols 20 and 20 adjacent to each other in the width direction. 20 ... are arranged at an equal pitch. Therefore, when the napkin 1 is discarded, when the napkin 1 and the packaging material 11 are overlapped, any one of the plurality of animal symbols 20 arranged along the width direction becomes the maximum diffusion region DR in the width direction. The possibility of duplication is higher and it is easier to conceal menstrual blood.

  In addition, when the napkin 1 and the packaging material 11 are overlapped, the longitudinal direction of the napkin 1 and the longitudinal direction of the packaging material 11 may be shifted from each other. For example, both may be overlapped so that the longitudinal direction of the napkin 1 and the longitudinal direction of the packaging material 11 intersect. Even in such a case, since the animal symbols 20, 20... Are regularly arranged at equal pitches in the longitudinal direction and the width direction, the animal symbol 20 and the maximum diffusion region DR easily overlap. It becomes easier to conceal blood.

  Further, in the packaging material 11 of the present embodiment, the animal symbols 20, 20,... Are provided in a staggered arrangement (see FIG. 3 and the like). By arranging the animal symbols 20 in a zigzag pattern, the ratio of the area of the animal symbol 20 per unit area of the packaging material 11 can be increased, and the animal symbols 20 and the maximum diffusion region DR may overlap. Can be further enhanced. Note that “staggered arrangement” means that two animal symbol rows adjacent in the longitudinal direction are shifted in the width direction when the animal symbol rows 20, 20. Say. In the example of FIG. 5, the positions of the animal symbol 20A (animal symbol 20D) and the animal symbol 20B are shifted in the width direction between the animal symbol sequence including the animal symbols 20A and 20D and the animal symbol sequence including the animal symbol 20B. Yes. In this specification, such a state is a staggered arrangement.

  Moreover, when the animal design 20 is staggered, when the napkin 1 is discarded, it is possible to make it difficult to visually recognize the maximum diffusion region DR when the napkin 1 is wrapped with the packaging material 11 as shown in FIG. 6A and 6B are diagrams illustrating a state when the napkin 1 is discarded by a method different from that in FIG. FIG. 6A is a plan view showing a state when the napkin 1 is folded in four in the longitudinal direction and then the packaging material 11 is wound around the outside. FIG. 6B is a schematic cross-sectional view showing the AA cross section of FIG. 6A. Many users of napkins have a desire to make menstrual blood adhering to the napkin after use difficult to see. Therefore, there is a case where the used napkin (napkin 1) is folded in half at the central portion in the longitudinal direction so that the skin side surface is inward, thereby trying to hide the skin side surface. And in order to discard in a more compact form, the napkin (napkin 1) is folded again in the longitudinal direction to form a four-fold state, and the packaging material (packaging material 11) is wound around the outside as shown in FIG. 6B, and the napkin is discarded. Operation is performed.

  Even when the packaging material 11 is wound around the napkin 1 in a four-fold state as shown in FIG. 6, menstrual blood (maximum diffusion region DR) attached to the napkin 1 is visible from the outside through the packaging material 11. There is. On the other hand, in the present embodiment, the animal pattern 20 is provided on the packaging material 11 so that the maximum diffusion region DR is hardly visible as described above. Furthermore, since the animal symbols 20 are arranged in a zigzag pattern (zigzag arrangement), the positions of the animal symbols 20 are dispersed in the region where the packaging material 11 overlaps in the thickness direction, overlapping the maximum menstrual blood diffusion region DR. It becomes easy to do.

  For example, in FIGS. 6A and 6B, animal symbols 20A and 20D are arranged on the outermost first layer 11s1 in the thickness direction of the packaging material 11, and are visible from the outside. Moreover, the animal design 20E is arrange | positioned at 2nd layer 11s2 overlaid inside the thickness direction of 1st layer 11s1 of packaging material 11 (lower side in FIG. 6B). The animal symbol 20E is visible through the first layer 11s1. At this time, the animal symbol 20E is located between the animal symbols 20A and 20D in the width direction as shown in FIG. 6A. That is, when viewed from the outside, the proportion of the area of the animal symbol 20 occupying the surface of the packaging material 11 is increased, and the probability that the menstrual blood maximum diffusion region DR overlaps with the animal symbol 20 increases. Therefore, the maximum menstrual diffusion region DR is more easily concealed by the animal symbol 20. Thus, menstrual blood and the like can be more effectively concealed by adjusting the arrangement of the animal symbol 20 in accordance with the usage mode assumed for the napkin 1 (packaging body 10).

  Moreover, it is desirable that the length L20 in the longitudinal direction of the animal pattern 20 is smaller than ¼ of the length L1 in the longitudinal direction of the napkin 1 (0.25 × L1> L20). When the napkin 1 is folded in four as shown in FIG. 6 and the packaging material 11 is wound outside, the visible range in the longitudinal direction of the packaging material 11 is 1/4 of the length in the longitudinal direction of the napkin 1. If the length L20 in the longitudinal direction of the animal symbol 20 is greater than 1/4 of the length L1 in the longitudinal direction of the napkin 1, the entire animal symbol 20 does not fit on the surface of the packaging material 11, and the longitudinal direction A part of will be interrupted. In this case, it is difficult to recognize that the animal symbol 20 is an “animal” symbol, and the psychological action based on the cute animal image described above is less likely to work.

  On the other hand, the length L20 in the longitudinal direction of the animal symbol 20 is made smaller than 1/4 of the length L1 in the longitudinal direction of the napkin 1, so that the packaging material 11 can be obtained even when the napkin 1 is folded in four. There is a high possibility that the entire animal symbol 20 is visually recognized on the surface. Therefore, the viewer's attention is more easily directed to the animal symbol 20 than menstrual blood, and menstrual blood (maximum diffusion region DR) can be made inconspicuous.

  Moreover, it is good to adjust the color of the packaging material 11 and the non-skin side sheet | seat 3 so that the color of the non-skin side sheet | seat 3 of the absorber 4 (napkin 1) and the color of the packaging material 11 may become a similar color relationship. . In the present embodiment, “similar colors” refer to colors that are adjacent to each other in a hue circle (for example, Ostwald hue circle). For example, “red (R)” and “orange (O)” have a similar color relationship.

  When the napkin 1 is discarded, the packaging material 11 is stacked on the non-skin side of the absorbent body 4 as described with reference to FIGS. That is, the non-skin side sheet 3 and the packaging material 11 are stacked in the thickness direction. At this time, if the two are in a similar color relationship, the outline of the animal symbol 20 colored in black is easily recognized even if it overlaps with the non-skin side sheet 3. That is, the black of the animal design 20 is easily visually recognized on both the packaging material 11 and the non-skin side sheet 3, and the effect of concealing menstrual blood by the animal design 20 is easily maintained.

  Conversely, the color of the packaging material 11 and the non-skin side sheet 3 so that the color of the non-skin side sheet 3 of the absorbent body 4 (napkin 1) and the color of the packaging material 11 are in an opposite color (complementary color). May be adjusted. In the present embodiment, “opposite color (capture color)” refers to a color on the opposite side of a hue circle (for example, Ostwald hue circle) and a similar color on both sides thereof. For example, “Sea Green (SG)” and “Leaf Green (LG)” are opposite colors to “Red (R)”.

  When the non-skin side sheet 3 and the packaging material 11 are opposite colors, the part where both are overlapped appears to be blackish as a whole. In this case, since menstrual blood itself is difficult to be visually recognized, an effect of concealing menstrual blood can be obtained.

  Further, the packaging material 11 may be provided with other symbols and patterns other than the animal symbol 20. FIG. 7 is a plan view illustrating the case where the stripe portion 25 is provided on the packaging material 11. In FIG. 7, in addition to the animal symbol 20, a plurality of strip-like stripe portions 25 along the longitudinal direction are provided at intervals in the width direction of the packaging material 11. However, the shape of the stripe portion 25 is not limited to the example of FIG. 7, and a plurality of strip-like stripes along the width direction may be provided at intervals in the longitudinal direction. The stripe part 25 in the present embodiment can be formed by printing in the same manner as the animal pattern 20.

  When the packaging material 11 having the stripe portion 25 extending in the longitudinal direction (or other direction) is overlapped on the non-skin side of the used napkin 1 as described above, at least a part of the stripe portion 25 is menstrual as shown in FIG. It overlaps with the maximum diffusion region DR. That is, the maximum diffusion region DR is divided by the stripe portion 25, and it becomes difficult to recognize the entire shape of the maximum diffusion region DR. As a result, the maximum diffusion region DR becomes inconspicuous. Moreover, by providing such a stripe part 25, while being able to improve the design property of the packaging material 11, the cute impression of the animal design 20 in the packaging material 11 can be enhanced. That is, it becomes easy to concentrate the viewer's attention from menstrual blood to the animal symbol 20. Thus, the effect of concealing menstrual blood (maximum diffusion region DR) can be further enhanced by combining the stripe portion 25 with the animal design 20.

  In addition, the stripe part 25 does not necessarily need to be formed over the whole longitudinal direction of the packaging material 11, and there may exist the location interrupted in the middle in the longitudinal direction. However, in order to divide the maximum diffusion region DR, the length in the longitudinal direction of the stripe portion 25 is preferably longer than the length Ldr in the longitudinal direction of the maximum diffusion region DR. Further, it is desirable that the length in the width direction of the stripe portion 25 is shorter than the length Wdr in the width direction of the maximum diffusion region DR.

  The stripe portion 25 desirably has a red color. The color of menstrual blood (maximum diffusion region DR) visually recognized from the non-skin side of the napkin 1 is dark red. Therefore, by forming the stripe portion 25 in the same color red, it is possible to make it difficult to recognize the shape of the maximum diffusion region DR when it overlaps with the maximum diffusion region DR. The “red line” refers to so-called “red” and colors close to it (pink, orange, etc.). For example, a color represented by “5R” in the Munsell color system and a plurality of colors included in a range of 5RP to 5YR adjacent to 5R in the Munsell hue ring.

  Moreover, it is desirable that the packaging material 11 is formed of a hydrophobic sheet member. When wrapping the outside (non-skin side) of the napkin 1 to which menstrual blood has adhered after use, menstrual blood oozes from the skin side of the packaging material 11 to the non-skin side, and the concealed menstrual blood is easily visible from the outside. This is to prevent the user from getting dirty or getting the user's hand dirty. In this embodiment, as described above, the packaging material 11 is formed of a liquid-impermeable film or the like, and the packaging material 11 is used even when the outside of the napkin 1 is wrapped as shown in FIGS. However, the menstrual blood can be concealed continuously even after the napkin 1 is discarded.

  Moreover, it is desirable that the animal pattern 20 and the stripe portion 25 are printed with hydrophobic ink and further provided on the skin side surface of the packaging material 11. In other words, when the napkin 1 is discarded, it is desirable that the surface of the packaging material 11 that is in contact with the non-skin side surface of the napkin 1 is printed with hydrophobic ink. With such a configuration, menstrual blood is likely to be repelled on the skin side surface of the packaging material 11 when overlapped with the napkin 1, and thus menstrual blood is prevented from spreading on the non-skin side surface of the packaging material 11. Can be more easily concealed.

  Further, it is preferable that the animal pattern 20 and the stripe part 25 have different easiness of playing liquid (menstrual blood). For example, by adjusting the type and amount of ink used for printing, in the packaging material 11, the region where the animal pattern 20 is formed is the other region (the stripe portion 25 and the portion where nothing is printed). ) Make it harder to play the liquid. With such a configuration, when menstrual blood leaks from the used napkin 1 that is rolled up when the napkin 1 is discarded, the leaked menstrual blood is easy to become familiar with the animal symbol 20, and the surroundings are more elastic. It becomes easy to be. Therefore, menstrual blood easily collects in the portion where the animal symbol 20 is printed, and menstrual blood is more easily concealed by the animal symbol 20.
