Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates not to sanitary products such as napkins, but to so-called panty liners, which are placed on the inner surface of panties to prevent underwear such as shorts from getting dirty. Yes, more specifically, it absorbs underwear contaminants such as vaginal discharge, and
The present invention relates to a panty liner that emits a scent or has a deodorant effect, making it more comfortable to wear.

[Prior art and the problem to be solved by the invention] According to a survey conducted by the present inventors, in recent years, a considerable number of people have felt discomfort and anxiety about secretions such as vaginal discharge, and about 80
It has even reached %.

Most of the reasons for this are stains on underwear such as shorts and the difficulty of removing the stains, but other reasons include the odor of secretions, wetness due to the fact that they are generally liquid, and discomfort due to the stains themselves.

In our country, no consideration is given to these needs at all, and naturally there are no products that meet these needs.

On the other hand, in response, it is clear that conventional sanitary products are not suitable for normal use. Furthermore, conventional sanitary products do not feel comfortable when worn, and are extremely inconvenient.

Furthermore, such needs are increasing as underwear becomes more luxurious in recent years, such as the popularity of silk underwear.

[Means to solve the problem]

The present invention has been made in view of the above problems, and its gist is a thin absorbent sheet consisting of 11 surface layers, an absorbent layer, and a leak-proof layer, in which the surface layer is a nonwoven fabric made of organic fibers, and the absorbent layer is a nonwoven fabric made of organic fibers. A plurality of sheets of pulp paper and a leak-proof layer are each formed of polymer resin laminated paper or polymer resin film, and at least one sheet of pulp paper between the absorbent layers is formed of a polymer resin laminated paper or a polymer resin film.
sandwiching a cyclodextrin clathrate fragrance between the two, and
A panty liner characterized in that the total sheet thickness is 2.5 m+n or less, and the organic fibers constituting the nonwoven fabric of the 21 surface layer are rayon or a blend of rayon and pulp. The panty liner described in 1. also includes 3. 4. The panty liner according to item 1 or 2 above, wherein a deodorant is sandwiched between at least one of the pulp papers of the absorbent layer.
．． 3. The panty liner according to item 3, wherein the deodorant is a powdered deodorant extracted from plants of the Camellia family.

In the present invention, firstly, a nonwoven fabric made of organic fibers is used for the surface layer covering the absorbent layer. Organic fibers include rayon, pulp, polyester, polypropylene, and polyethylene/polypropylene composite M! Male, acetate, ethylene/vinyl acetate/polypropylene composite fiber,
Cupro, polyvinyl chloride, cotton, etc. Rayon,
Pulp is particularly preferred.

On the opposite side of the absorbent layer, a leak-proof layer made of polymer resin laminated paper such as polyethylene laminated paper or polymer resin film is provided, thereby preventing leakage into underwear such as shorts. Examples of the polymer resin include polyethylene, polypropylene, polyvinyl alcohol, polypropylene/polyethylene ionomer resin, and the like.

The absorbent layer is composed of multiple sheets of pulp paper.

Secretions such as vaginal discharge targeted by the present invention are usually 0.2 to
1. Since it is Oml, the pulp paper is about 20g/a+'', and 8 sheets is sufficient.

In order to keep the total thickness of the panty liner during use to 2.5 nm or less, the number of panty liners is preferably 10 or less.

As the pulp paper, it is preferable to use veined pulp paper. This is because the panty liner of the present invention is intended for highly viscous secretions such as vaginal discharge, and is therefore required to have high liquid absorbency. By adding a streak pattern, the absorbency and the diffusion of the absorbed liquid into the pulp paper can be improved.

Furthermore, in the present invention, a cyclodextrin clathrate fragrance is sandwiched between at least one of the pulp papers of the absorbent layer. The cyclodextrin clathrate fragrance in the present invention is one in which the fragrance used in -a is included in cyclodextrin, and the cyclodextrin may be β-type, β-type, γ-type, or a mixture thereof. By sandwiching this cyclodextrin clathrate fragrance between the pulp papers of the absorbent layer, it is possible to emit a fragrance during and after use of the panty liner of the present invention.

A major feature of the present invention is that the total sheet thickness of the panty liner configured as described above is 2.51 am or less. In other words, the problem of the present invention is to prevent underwear from being soiled by underwear contaminants such as normal vaginal discharge mainly during non-menstrual periods [or to relieve the discomfort caused by vaginal discharge, etc.]. This is because a thickness of 10% would cause too much deterioration in the feeling of use. Naturally, other structural requirements are also restricted by this condition, and the balance of materials, thickness, etc. is also important.

In the second aspect of the invention, a nonwoven fabric made of rayon or a blend of rayon and pulp fibers is used for the surface layer covering the absorbent layer. -Generally, vaginal discharge contains mucin and is highly viscous, so it is difficult to absorb, but by using a nonwoven fabric made of rayon or 1aII, a blend of rayon and pulp, panties with good absorption properties against vaginal discharge, etc. It is possible to provide a liner. In addition, the texture of the skin can be improved, and secretions such as vaginal discharge are usually 0.2 to 1. Since it is Oml, it does not leave a wet feeling on the surface layer.

The invention of claim 3 of the present application is characterized in that, in addition to the invention of claim 1 or 2, a deodorant is sandwiched between at least one of the pulp papers of the absorbent layer. This results in
In addition to having an aromatic effect, it also has a deodorizing effect, removing bad odors such as vaginal discharge, and greatly improving the feeling of use.

As the deodorant, a deodorant containing a polyphenol structure or flavans is preferred. Examples of polyphenol structures include gallocatechin and catechin kasa. Examples of flavans include oxypentamethylflavan. Since the polyphenol structure has a phenol group, it is thought that it creates a chain compound and combines with the malodorous component, or polyphenols combine to create a three-dimensional structure and include the malodorous component to deodorize it. In addition, flavans are thought to form clathrate compounds to deodorize.

The invention according to claim 4 of the present application is characterized in that, in the invention according to claim 3, a deodorizing agent made from a plant extract of the Camellia family is used as the deodorant. The powdered deodorant extracted from plants of the Camellia family contains both polyphenol structures and flavans.

According to the research conducted by the present inventors, the malodorous component of vaginal discharge is acetic acid, and it has been found that the Camellia plant extract and deodorizing shaver can effectively remove the malodor of butyric acid. In addition, the powdered deodorant from Camellia family plant extract is extremely safe for human skin, and in the panty liner of the present invention, which comes into direct contact with human skin and has a thin layer that envelops the deodorant, It is the most preferred deodorant.

Furthermore, the consumers of the panty liner of the present invention are women, and 5
It is also important not to interfere with the fashionability of the product. That is, the panty liner of the present invention is required to be thin and thin, and for this reason, the pulp layer covering the deodorant, etc.
The surface layer must also be thin; if it is colored, such as activated carbon, it will show through and spoil the appearance of the panty liner. The Camellia family plant extract powder deodorant is white in color, and its use has the effect of not damaging the appearance of panty liners.

Furthermore, in the present invention, it is more preferable that the deodorant or cyclodextrin clathrate fragrance is sandwiched between the paper layers in the center of the plural pulp paper layers of the absorbent layer. This is because if a deodorant or cyclodextrin clathrate fragrance is sandwiched between layers close to the surface layer, it may inhibit the absorbency of the absorbent layer.On the other hand, if it is sandwiched between paper layers close to the leak-proof layer, This is because the deodorizing effect or fragrance effect may be insufficient.

[For production]

The present invention efficiently absorbs underwear contaminants such as vaginal discharge, prevents underwear from becoming soiled, and emits a fragrance as the underwear contaminants are absorbed. Furthermore, claim 2
The third invention also has a deodorizing effect on the bad odor of underwear contaminants such as vaginal discharge.
