Description

The present invention relates to an absorbent article comprising an indicator that is discolored by urine.

For example, an absorbent article such as a diaper is provided with an indicator that is discolored by urine (Patent Document 1). The absorbent article described in Patent Document 1 has a character symbol provided on the outer cover and a plurality of discretely arranged indicator symbols. In Patent Document 1, the character symbol and the indicator symbol are formed by symbols that are related to each other. Thereby, an absorbent article having a high design property can be provided.

Patent No. 4721598

The absorbent article described in Patent Document 1 includes a character symbol that does not react to urine and an indicator symbol that reacts to urine. In this case, it may be difficult for a user such as an infant and an assistant such as a parent to distinguish between a character symbol and an indicator symbol. Therefore, it may be difficult for the user and the assistant to know which symbol should be viewed in order to determine whether or not the urine has adhered to the absorbent article.

Therefore, an absorbent article that makes it easy to recognize the difference between a symbol that does not respond to urine and an indicator symbol that responds to urine is desired.

The absorbent article according to one embodiment has an indicator provided in the front waist area, the rear waist area, the inseam area between the front waist area and the rear waist area, and at least the inseam area, and is discolored by urine. Includes an indicator symbol and a back surface symbol that is visible from the non-skin surface side and is different from the indicator symbol. At least the indicator symbol provided in the inseam region includes a symbol formed by the indicator and a separating element surrounding the symbol and visible from the non-skin surface side.

It is a top view of the absorbent article which concerns on one Embodiment. It is sectional drawing of the absorbent article along the line 2A-2A of FIG.

(1) Outline of the Embodiment The absorbent article according to one embodiment is provided in the front waist circumference area, the rear waist circumference area, the inseam area between the front waist circumference area and the rear waist circumference area, and at least the inseam area. , An indicator symbol including an indicator that is discolored by urine, and a back surface symbol that is visible from the non-skin surface side and is different from the indicator symbol, and the indicator symbol provided at least in the inseam area is the indicator. Includes a symbol formed by the above pattern and a separating element that surrounds the symbol and is visible from the non-skin surface side.

The pattern formed by the indicator that responds to urine is surrounded by a separating element. Therefore, the user and the assistant recognize the symbol surrounded by the separating element as an indicator, and easily distinguish the symbol not surrounded by the separating element as the back surface symbol. Therefore, the user and the assistant can easily understand which symbol should be viewed in order to determine whether or not the urine has adhered to the absorbent article.

According to a preferred embodiment, the separating element is formed by an indicator that is discolored by urine.

The indicator symbol is formed so that the separation element is discolored by urine together with the symbol formed by the indicator. Therefore, it becomes easier for the user and the assistant to distinguish between the discolored indicator symbol and the back surface symbol. This makes it easier for users and assistants to see which symbol to look at in order to determine if urine has adhered to the absorbent article.

According to a preferred embodiment, the shortest distance between the indicator symbol and the back surface symbol is shorter than the maximum length of the indicator symbol.

Since the distance between the indicator symbol and the back surface symbol is relatively small, the user or the assistant can easily see the indicator symbol and the back surface symbol in comparison with each other. This makes it easier to recognize the difference between the indicator symbol and the back symbol at a glance.

According to a preferred embodiment, the indicator symbol reaches at least one of the anterior girth region and the posterior girth region from the inseam region.

Since urine diffuses concentrically from the point of attachment (inseam area), discoloration of the indicator symbol occurs from the inseam area toward the anterior girth area or the posterior girth area. In this embodiment, the indicator symbol reaches at least one of the anterior girth region and the posterior girth region from the inseam region. Therefore, a boundary of discoloration of the indicator symbol is likely to occur in the inseam region and the front waist circumference region or the rear waist circumference region, and it is possible to assist the recognition of the user or the assistant who recognizes that the discolored symbol is the indicator symbol. This makes it easier for the user or the assistant to determine to what extent the urine adhering to the absorbent article reaches the anterior girth region and / or the posterior girth region.

According to a preferred embodiment, the length of the indicator symbol in the width direction of the absorbent article is 10 mm or more and 20 mm or less.

Users such as infants often wear underwear that allows the inseam area to be opened, such as rompers. In this case, an assistant such as a parent visually recognizes an indicator symbol provided in the inseam area of the absorbent article by opening the inseam area of the underwear, and determines whether or not urine is attached.

Here, in underwear such as a romper, a gap of about 30 mm may occur in the inseam region in the width direction. In this case, since the length of the indicator symbol in the width direction is 20 mm or less, the area around the indicator symbol can be sufficiently visually recognized, so that the user and the assistant recognize the indicator symbol by the difference from the surrounding area. It will be easier.

Further, when the length of the indicator symbol in the width direction is 10 mm or more, the indicator symbol is prevented from becoming too small, and the user and the assistant can easily recognize the indicator symbol.

According to a preferred embodiment, a plurality of the indicator symbols are arranged at intervals in the first direction, and the distance between the indicator symbols in the first direction is the length of the indicator symbols in the first direction. Shorter than that.

Since the plurality of indicator symbols are arranged in the first direction at relatively short intervals, the user and the assistant can easily recognize the indicator symbols. In addition, it becomes easy to determine to which part of the indicator symbol the urine reaches.

According to a preferred embodiment, the indicator symbols are arranged in a plurality of positions in the first direction at a pitch of 10 mm or more and less than 30 mm.

In underwear such as a romper, a gap of about 30 mm is generated in the inseam region in the front-back direction (first direction). In this embodiment, since a plurality of indicator symbols are lined up at a pitch of 10 mm or more and less than 30 mm, at least one indicator symbol as a whole can be confirmed from a gap of about 30 mm.

According to a preferred embodiment, the length of the indicator symbol in the first direction is 15 mm or more.

In underwear such as a romper, a gap of about 30 mm is generated in the inseam region in the front-back direction (first direction). In this embodiment, since the indicator symbol is 15 mm or more, the size of the indicator symbol can be secured for a gap of about 30 mm. This makes it easier for the user or the assistant to recognize the indicator symbol from a gap of about 30 mm.

According to a preferred embodiment, a plurality of the back surface symbols are provided, and the distance between the back surface symbols is longer than the maximum length of the back surface symbols.

Since a plurality of backside symbols are provided at relatively large intervals, it is easy for the user and the assistant to recognize the difference between the indicator symbol and the backside symbol.

According to a preferred embodiment, a plurality of the indicator symbols are arranged side by side in the first direction, and the types or orientations of the indicator symbols adjacent to each other are different from each other.

Since the types or orientations of the indicator symbols adjacent to each other are different, it becomes easy for the user and the assistant to determine to which part of the indicator symbols the urine reaches.

In addition, an assistant such as a parent can be one of the triggers for communication between mother and child by transmitting information to a user such as an infant about which type or orientation the indicator symbol reaches.

According to a preferred embodiment, the indicator symbol reaches both the front waist circumference region and the rear waist circumference region from the inseam region, and a plurality of the indicator symbols are arranged in the front-rear direction, and the front waist circumference region. The orientation of the indicator symbol in the above is reversed from the orientation of the indicator symbol in the rear waist circumference region.

Since the orientation of the indicator symbol is reversed in the front waist circumference area and the rear waist circumference area, the design of the absorbent article can be improved and the front and back can be distinguished more clearly.

According to a preferred embodiment, the separating element is doubly formed. Since the indicator symbol is conspicuous due to the double formation of the separating element, the indicator symbol is more easily visible by the user and the assistant, and the user and the assistant are more aware of the difference between the indicator symbol and the back surface symbol. It will be easier.

According to a preferred embodiment, the indicator symbol and the back surface symbol are formed by related symbols.

Since the indicator symbol and the back surface symbol are formed by symbols that are related to each other, the design of the absorbent article can be improved. As a result, it is possible to improve the purchasing motivation of the user and / or the user.

According to a preferred embodiment, the color of the indicator symbol discolored by urine is formed by a color belonging to a color opposite to the color of the back surface symbol.

This makes it easier for the user and the assistant to recognize the difference between the indicator symbol and the back surface symbol.

According to a preferred embodiment, the separating element has a shape that borders the outer shape of the symbol formed by the indicator.

As a result, the indicator symbol has a more distinctive shape and is more noticeable to the user and the assistant. Therefore, the user and the assistant can more easily recognize the difference between the indicator symbol and the back surface symbol.

(2) Detailed explanation of the embodiment

Next, the absorbent article according to the embodiment will be described with reference to the drawings. In this embodiment, the absorbent article is a tape-type disposable diaper. Instead, the absorbent article may be a pants-type disposable diaper. The disposable diaper may be a diaper for infants or a diaper for adults.

In the description of the drawings below, the same or similar parts are designated by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratio of each dimension is different from the actual one. Therefore, the specific dimensions, etc. should be determined in consideration of the following explanation. In addition, there may be a portion where the relationship and ratio of the dimensions of the drawings are different from each other.

FIG. 1 is a plan view of an absorbent article according to an embodiment. More specifically, FIG. 1 shows a state in which the absorbent article pulled until the wrinkles are substantially eliminated is viewed from the non-skin surface side. FIG. 2 is a cross-sectional view of the absorbent article along line 2A-2A of FIG. Here, the non-skin surface or the non-skin surface side means a surface or a side facing the side opposite to the wearer's skin in the wearing state of the absorbent article. On the other hand, the skin surface or the skin surface side means a surface or a side facing the wearer's skin when the absorbent article is worn.

The absorbent article 10 has an anteroposterior direction L, a width direction W, and a thickness direction. The anteroposterior direction L is a direction connecting the ventral side and the dorsal side of the absorbent article 10 in the worn state. The width direction W is a direction orthogonal to the front-rear direction L in the plan view of the absorbent article 10. The thickness direction is a direction orthogonal to both the front-rear direction L and the width direction W.

The absorbent article 10 has a front waist circumference region S1, an inseam region S2, and a rear waist circumference region S3. The front waist circumference area S1 is a region facing the front waist circumference of the wearer when the absorbent article is used. The rear waist circumference area S3 is a region facing the rear waist circumference of the wearer when the absorbent article is used. The inseam area S2 is an area located in the inseam of the wearer when the absorbent article is used, and is located between the front waist area S1 and the rear waist area S3.

The absorbent article 10 may have a front surface sheet 50, a back surface sheet 62, and an absorber 40. The surface sheet 50 is located on the skin surface side of the absorber 40. The surface sheet 50 covers the skin surface side of the absorber 40. The surface sheet 50 may be composed of a liquid permeable sheet.

The absorbent article 10 may have side sheets 52 on both sides of the absorbent article 10 in the width direction W. The side sheet 52 may be located closer to the skin surface than the surface sheet 50. In the present embodiment, the side sheet 52 is provided from the vicinity of the outside in the width direction W of the absorbent article 10 to the vicinity of the outside in the width direction W of the absorber 40. More specifically, a part of the side sheet 52 may overlap with the outer portion of the absorber 40 in the width direction W in the thickness direction.

An elastic member 30 that can be expanded and contracted in the front-rear direction may be provided near the inside of the side sheet 52 in the width direction W. More specifically, the elastic member 30 is joined to the side sheet 52 in a stretched state. As a result, the side seat 52 is naturally contracted in the front-rear direction L. Due to the contraction of the side seat 52 in the front-rear direction L, a cuff (gather) is formed in which the inner portion of the side seat 52 in the width direction stands up toward the skin side.

The back sheet 62 is located on the non-skin surface side of the absorber 40. The back sheet 62 may be composed of a non-permeable sheet. The back sheet 62 suppresses the leakage of liquid from the absorber 40 to the non-skin side.

The absorbent article 10 may have an exterior sheet 60 on the non-skin side of the back sheet 62. The exterior sheet 60 may be composed of a sheet having a hole (opening) 61 in order to improve the air permeability.

The absorber 40 may have an absorption core 40a and a core wrap 40b. The absorption core 40a is made of a material capable of absorbing a liquid such as urine. The absorption core 40a may be composed of, for example, pulp, a super absorbent polymer (SAP), or a combination thereof.

The core wrap 40b may wrap the absorption core 40a. The core wrap 40b may be composed of a sheet such as tissue.

In the present embodiment, the core wrap 40b is folded back so that a pair of ends located at both ends of the core wrap 40b overlap each other on the skin surface side of the absorption core 40a in the unfolded state (see region O in FIG. 2). .. The core wrap 40b may be joined by at least double overlapping overlapping portions O.

The absorbent article 10 includes an indicator symbol 80 that includes an indicator that is discolored by urine, and a back surface symbol 70 that is visible from the non-skin surface side and is different from the indicator symbol 80.

A plurality of back surface symbols 70 may be provided. The back surface pattern 70 may be provided on any sheet constituting the absorbent article 10 as long as it can be visually recognized from the non-skin surface side. For example, the back surface symbol 70 may be provided on the back surface sheet 62. The back surface pattern 70 may be colored, for example. It should be noted that the back surface symbol 70 is not composed of an indicator that reacts with urine as described later.

The indicator symbol 80 is provided at least in the inseam region S2. The indicator constituting the indicator symbol 80 can indicate the wetting of the absorbent article 10 by, for example, discoloring with urine. The indicator symbol 80 may be provided on the back sheet 62. Preferably, the indicator symbol 80 may be provided on the surface of the back sheet 62 facing the absorber 40 side.

At least the indicator symbol 80 provided in the inseam region S2 includes a symbol 84 formed by the indicator and a separating element 88 surrounding the symbol 84 and visible from the non-skin surface side. The separating element 88 is preferably formed by an indicator that is discolored by urine.

The symbol 84 formed by the indicator that responds to urine is surrounded by the separating element 88. Therefore, the user and the assistant recognize the symbol 84 surrounded by the separation element 88 as an indicator, and easily distinguish the symbol not surrounded by the separation element 88 as the back surface symbol 70. Therefore, the user and the assistant can easily understand which symbol should be viewed in order to determine whether or not the urine has adhered to the absorbent article.

Further, when the separation element 88 is also formed by the indicator, the separation element 88 is also discolored by urine together with the symbol 84 formed by the indicator, so that the user and the assistant can easily recognize the indicator symbol 80 as characteristic. Become. Therefore, it becomes easier for the user and the assistant to distinguish between the discolored indicator symbol 80 and the back surface symbol 70. This makes it easier for the user and the assistant to know which symbol should be viewed in order to determine whether or not urine has adhered to the absorbent article 10.

The separating element 88 may have a shape that borders the outer shape of the symbol 84 formed by the indicator. In the example shown in FIG. 1, the separating element 88 has a quadrangular shape surrounding the symbol 84 formed by the indicator. As an example, the separating element 88 may be formed so as to surround the symbol 84 at a distance within 6 mm from the symbol 84 formed by the indicator.

If the separating element 88 has a shape that borders the outer shape of the symbol 84 formed by the indicator, the indicator symbol 80 has a more characteristic shape and is more noticeable to the user and the assistant. Therefore, the user and the assistant can more easily recognize the difference between the indicator symbol 80 and the back surface symbol 70.

In FIG. 1, one separating element 88 surrounds a symbol 84 formed by an indicator. Instead, the separating element 88 may be doubly formed. When the separating element 88 is doubly formed, the indicator symbol 80 is more conspicuous, so that the indicator symbol is more easily visible by the user and the assistant. This makes it easier for the user and the assistant to recognize the difference between the indicator symbol 80 and the back surface symbol 70.

A plurality of indicator symbols 80 may be arranged side by side at intervals in one direction. In the present embodiment, the indicator symbols 80 are arranged along the front-rear direction L. The distance L5 between the indicator symbols 80 adjacent to each other is preferably shorter than the length L4 of the indicator symbols 80 in the direction in which the indicator symbols 80 are lined up. As a result, since the plurality of indicator symbols 80 are arranged in one direction at relatively short intervals, the user and the assistant can easily distinguish the indicator symbol 80 from the back surface symbol 70. Further, since the indicator symbols 80 are arranged in one direction at relatively short intervals, it becomes easy to determine to which region of the absorbent article 10 the urine reaches.

It is preferable that a plurality of indicator symbols 80 are arranged in one direction, for example, in the front-rear direction L at a pitch of 10 mm or more and less than 30 mm. In underwear such as a romper, when the button at the position facing the inseam area S2 is removed, a gap of about 30 mm is generated in the inseam area S2 in the front-rear direction L. If a plurality of indicator symbols 80 are lined up at a pitch of 10 mm or more and less than 30 mm, the entire indicator symbol 80 can be confirmed from a gap of about 30 mm (romper gap). Thereby, the user and the assistant can easily grasp whether or not urine is attached to the inseam region S2 of the absorbent article from the gap of the romper.

It is preferable that the indicator symbol 80 reaches at least one of the front waist circumference area S1 and the rear waist circumference region S2 from the inseam region S2. More preferably, the indicator symbol 80 reaches both the front waist circumference area S1 and the rear waist circumference region S2 from the inseam region S2.

Since urine diffuses concentrically from the point of attachment (inseam area), discoloration of the indicator symbol 80 occurs from the inseam area S2 toward the anterior girth area S1 or the posterior girth area S3. When the indicator symbol 80 reaches at least one of the front waist circumference area S1 and the rear waist circumference region S3 from the inseam region S2, a discoloration boundary of the indicator symbol 80 is likely to occur in the front waist circumference region S1 or the rear waist circumference region S3. This can help the user or the assistant who recognizes that the discolored symbol is the indicator symbol. Therefore, the user or the assistant can easily determine to what extent the urine adhering to the absorbent article 10 reaches the front waist circumference region S1 and / or the rear waist circumference region S3.

The length of the indicator symbol 80 in the width direction W of the absorbent article 10 is preferably 10 mm or more and 20 mm or less. Users such as infants often wear underwear that allows the inseam area to be opened, such as rompers. In this case, an assistant such as a parent visually recognizes an indicator symbol provided in the inseam area of the absorbent article by opening the inseam area of the underwear, and determines whether or not urine is attached. Here, in underwear such as a romper, a gap of about 30 mm may occur in the inseam region in the width direction. In this case, since the length of the indicator symbol 80 in the width direction W is 20 mm or less, the area around the indicator symbol 80 can be sufficiently visually recognized, so that the user and the assistant can see the indicator symbol due to the difference from the surrounding area. It becomes easy to recognize 80.

Further, when the length of the indicator symbol 80 in the width direction W is 10 mm or more, the indicator symbol 80 is prevented from becoming too small, and the user and the assistant can easily recognize the indicator symbol 80.

In the direction in which the indicator symbols 80 are lined up, for example, in the front-rear direction L, the length of the indicator symbols 80 is preferably 15 mm or more. In underwear such as rompers, a gap of about 30 mm may occur in the inseam region, as described above. Therefore, if the length of the indicator symbol 80 is 15 mm or more, the size of the indicator symbol 80 can be secured for a gap of about 30 mm. This makes it easier for the user or the assistant to recognize the indicator symbol 80 from a gap of about 30 mm.

In order to make it easier for the user or an assistant to recognize the indicator symbol, it is preferable to make one, preferably two indicator symbols visible from a gap of about 30 mm. Further, it is more preferable that the number of indicator symbols visible from a gap of about 30 mm is less than 3 so that the indicator symbol 80 does not become too small. Considering such conditions, the length of the indicator symbols 80 in one direction may be in the range of 9 to 29 mm, and the distance between the indicator symbols 80 may be in the range of 1 to 21 mm.

The shortest distance L1 between the indicator symbol 89 and the back surface symbol 70 is preferably shorter than the maximum length L2 of the indicator symbol 80. More preferably, the shortest distance L1 between the indicator symbol 89 and the back surface symbol 70 is shorter than the length L3 of the indicator symbol 80 in the direction orthogonal to the direction in which the indicator symbols 80 are arranged, for example, the width direction W. This makes it easier for the user or the assistant to visually recognize the indicator symbol 80 and the back surface symbol 70 in comparison with each other. Therefore, it becomes easy to recognize the difference between the indicator symbol 80 and the back surface symbol 70 at a glance.

A plurality of back surface symbols 70 are provided, and it is preferable that the distance between the back surface symbols 70 is longer than the maximum length of the back surface symbols 70. When a plurality of back surface symbols 70 are provided at relatively large intervals, the user and the assistant can easily recognize the difference between the indicator symbol 80 and the back surface symbol 70. In particular, when the distance L5 between the indicator symbols 80 is shorter than the length L4 of the indicator symbol 80, the difference between the indicator symbol 80 and the back surface symbol 70 becomes remarkable.

Preferably, a plurality of indicator symbols 80 are arranged in a first direction, for example, in the front-rear direction L, and the types or orientations of the indicator symbols 80 adjacent to each other are different from each other. In the example shown in FIG. 1, the types of indicator symbols 80 adjacent to each other imitate a flower and a bee. Instead, the indicator symbols 80 adjacent to each other may be the same and may differ only in their orientation. As described above, when the types or orientations of the indicator symbols 80 adjacent to each other are different, it becomes easy for the user and the assistant to determine to which part of the indicator symbol 80 the urine reaches. In addition, an assistant such as a parent can be one of the triggers for communication between mother and child by transmitting information to a user such as an infant about which type or orientation the indicator symbol 80 has reached.

Preferably, the orientation of the indicator symbol 80 in the front girth region S1 may be reversed from the orientation of the indicator symbol 80 in the rear girth region S3. When the directions of the indicator symbols 80 are reversed in the front waist circumference area S1 and the rear waist circumference area S3, the design of the absorbent article 10 can be improved and the front-back distinction can be made clearer.

It is preferable that the indicator symbol 80 and the back surface symbol 70 are formed by related symbols. For example, in the example shown in FIG. 1, the indicator symbol 80 is composed of a flower and a bee symbol, and the back surface symbol 70 is composed of a flower symbol. As a result, a design with a sense of unity can be obtained as a whole.

In this way, the indicator symbol 80 and the back surface symbol 70 are formed of symbols that are related to each other, so that the design of the absorbent article 10 can be improved. As a result, it is possible to improve the purchasing motivation of the user and / or the user.

The color of the indicator symbol 80 discolored by urine is preferably formed by a color belonging to a color opposite to the color of the back symbol 70. Here, the opposite color of a certain color is the complementary color of a certain color (the color located on the opposite side of the color wheel) and one and two of the complementary colors in the Munsell color system based on the Munsell color system obtained by dividing the hue into 20 equal parts. It shall mean the next color.

When the color of the indicator symbol 80 after the color change is formed by a color belonging to a color opposite to the color of the back surface symbol 70, the user and the assistant can more easily recognize the difference between the indicator symbol 80 and the back surface symbol 70.

Although the present invention has been described in detail using the above-described embodiments, it is clear to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modifications and modifications without departing from the spirit and scope of the present invention as determined by the description of the scope of claims. Therefore, the description of the present specification is for the purpose of exemplifying explanation and does not have any limiting meaning to the present invention.

For example, the separating element 88 is preferably formed by an indicator that is discolored by urine, as described above. However, the separating element 88 does not necessarily have to be formed by an indicator. For example, the separation element 88 may be formed by an ink layer (coloring), or may be formed by a region (ground color) sandwiched between the ink layers (coloring).

According to this aspect, it is possible to provide an absorbent article in which it is easy to recognize the difference between a symbol that does not react with urine and an indicator symbol that reacts with urine.
