Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement in sanitary shorts that are used by attaching a sanitary napkin to the inner surface of the groin area.

Conventional technology and its problems Conventionally, sanitary shorts generally have a waterproof sheet material made of cloth laminated with a waterproof thin film such as a resin sheet on the inner surface of the crotch area of the shorts body made of cloth such as cotton knit fabric. The sanitary napkin is used by placing the fabric side on the front side and the waterproof thin film side on the overlapping side, and then attaching the sanitary napkin to the fabric side surface of the waterproof sheet material on the inner side of the crotch area. By doing so, physiological substances such as blood are absorbed into the napkin, and the physiological substances are prevented from seeping out of the shorts by the waterproof thin film layer of the waterproof sheet material. In this case, the waterproof sheet material is constructed by laminating a waterproof thin film such as a resin sheet onto cloth, and the waterproof thin film is laminated onto the inner surface of the crotch area of the shorts body, with the fabric side facing up and the waterproof thin film side facing up. That is, the reason why it is done inside is to eliminate the unpleasant feeling when a waterproof thin film comes into direct contact with the skin, and to improve the tactility by using the fabric as the surface that comes into contact with the skin. The materials used to form this waterproof sheet material are generally tricot fabric, for example, and the waterproof thin film is made of polyurethane or other materials that are not only waterproof but also breathable to prevent stuffiness. A suitable synthetic resin may be used. In recent years, sanitary napkins have been commercially available in large quantities as ready-made sanitary napkins made of liquid-absorbing fiber materials such as cotton, filled with liquid-absorbing agents, and then wrapped in non-woven fabric. , it has become common to use this, but in this case, recently pressure-sensitive adhesive tape (adhesive tape) such as double-sided adhesive tape is used partially in place on one side of the napkin.
It has become common to use adhesive tape on the fabric side surface of the waterproof sheet material on the inner side of the crotch area of the shorts to prevent the napkin from slipping. Efforts have been made to prevent it.

However, even though napkins are attached with adhesive tape, as mentioned above, in conventional sanitary shorts, the waterproof sheet material that is attached to the inside of the crotch area is placed with the fabric side facing up. As a result, the napkin adheres to the fabric, which has poor adhesion and is not very effective in preventing the napkin from slipping, causing the napkin to slip during use.

In this regard, in the past, for example, some sanitary shorts were equipped with something like a clamp on the front side of the crotch area, and the front end of the napkin to be applied was clamped and stabilized. This has the disadvantage that the structure of the shot becomes complicated and expensive, and even more troublesome is required to handle it.

Purpose of the present invention Therefore, the purpose of the present invention is to improve the effectiveness of the adhesive tape when using a napkin stacking device that uses adhesive tape to adhere onto the fabric side surface of the waterproof sheet material on the inner surface of the crotch area. To provide sanitary shorts which can securely prevent a napkin from slipping when raised and can achieve this with a simple configuration.

Structure of the present invention The present invention is based on the above-mentioned conventional menstrual shorts, namely:
A waterproof sheet material made by laminating a waterproof thin film such as a resin sheet on cloth is attached to the inner surface of the crotch area of the cloth shorts body, with the fabric side facing up and the waterproof thin film side facing the overlapping side. Then, on the fabric side surface of the waterproof sheet material on the inner side of the crotch area, a sanitary napkin partially provided with pressure-sensitive adhesive tape on one side is attached by adhering it with the pressure-sensitive adhesive tape. In sanitary shorts used as a sanitary short, an adhesive tape that strongly adheres at least a portion of the pressure-sensitive adhesive tape provided on the napkin to the fabric side surface of the waterproof sheet material on the inner side of the crotch area where the napkin is applied. It is characterized by partially providing a smooth surface portion for adhesion.

Effects of the present invention According to the sanitary shorts of the present invention, an extremely simple additional feature is provided in which a smooth surface portion for adhering adhesive tape is partially provided on the fabric side surface of the waterproof sheet material that is overlapped on the inner surface of the crotch area. The structure allows the adhesive tape provided on the napkin to bond strongly and effectively on the smooth surface, ensuring that the napkin is firmly and stably placed in the optimal position without any risk of slipping. It can be made and used comfortably and advantageously. In this case, the smooth surface portion is not provided on the entire surface of the fabric side of the waterproof sheet material, but is only provided partially for adhesion of the adhesive tape, so the smooth surface portion does not come into direct contact with the skin. Or, even if it comes into contact, it can be limited to a part of the crotch that does not have a negative impact on the feel, and direct contact with the skin can be made with the fabric of the waterproof sheet material, which is almost the same as before, and the touch is not so bad. The properties are good without any deterioration.

In the present invention, the smooth surface part for adhering the adhesive tape is generally made of a suitable resin such as natural resin such as rubber or synthetic resin such as polyurethane, polyester, or vinyl chloride, and this is used as a waterproof sheet material. It is preferable to coat a desired part of the fabric side surface of the fabric, or to fix it in the form of an ultra-thin sheet by firmly adhering or sewing it with a suitable heat-sensitive or pressure-sensitive adhesive. In addition, instead of that, the smooth surface part is provided with a part where the waterproof sheet material is partially turned inside out,
In other words, by providing a required portion of the waterproof sheet material with the cloth side facing inside and the waterproof thin film side such as a resin sheet facing the front side, this can be used in the waterproof thin film that is placed on the front side. It can also be configured to be formed by Furthermore, instead of that, the smooth surface part can be made into a waterproof sheet material.
By partially providing a portion where only the fabric layer is cut out, it is also possible to construct a waterproof thin film layer such as a resin sheet that remains on the front side in the cut portion. In this way, the structure can be easily implemented.

In addition, regarding the part where the smooth surface part is provided, it is only necessary to set it in a part that can correspond to the attachment position of the adhesive tape on various ready-made commercially available napkins. If it is set at a position close to the front side of the crotch within the surface area of the fabric side of the waterproof sheet material, it can be used in most cases satisfactorily.

Embodiments of the present invention Examples of the present invention will be described below with reference to the drawings.

The sanitary shorts shown in Fig. 1 is made of a fabric shorts body 1 made of knitted fabric such as cotton, and has an inner side surface area from the front to the back of the crotch area 2, so as to cover this area. In addition, a waterproof sheet material 3 shaped approximately in the shape of a weight pattern is overlaid (lined). The waterproof sheet material 3 is made of a cloth 3a such as a knit fabric or a woven fabric such as a tricot fabric made of natural, chemical or synthetic fibers, and a suitable resin sheet such as polyurethane which preferably has breathability in addition to waterproofness. The waterproof thin film 3b is laminated with the fabric 3a side facing up.
The cloth shorts body 1 is stacked with its side facing the inner surface of the crotch portion 2 of the shorts body 1. The attachment is done by sewing the circumferential edges of the overlapped waterproof sheet materials 3 to the fabric of the shorts body 1.

Thus, this sanitary short is a sanitary napkin that is generally widely available as a ready-made product and is partially provided with pressure-sensitive adhesive tape (adhesive tape) such as double-sided adhesive tape on one side. It is used (worn) by being attached to the cloth 3a side surface of the waterproof sheet material 3 on the inner side of the crotch area 2 by adhering it with adhesive tape, and absorbs physiological substances such as blood into the napkin. The waterproof thin film 3b layer of the waterproof sheet material 3 prevents physiological substances from seeping out of the shorts. By placing the fabric 3a side of the waterproof sheet material 3 on the front side and the waterproof thin film 3b side on the inside as the overlapping surface side, the waterproof thin film 3b does not come into direct contact with the skin, and the fabric 3a becomes the contact surface side. In particular, it provides good tactility.

In the case of such shorts, the adhesive surface of the adhesive tape on the napkin is the fabric surface 3a, so even if it is adhered at all costs, the adhesiveness is poor and the napkin easily slips when worn.

The present invention provides some preferred embodiments of such shots as shown in FIGS. 2 to 5.
Smooth surface portion 4 for adhesion of adhesive tape that strongly adheres at least a portion of the pressure-sensitive adhesive tape 13 provided on the napkin 10 to the fabric 3a side surface of the waterproof sheet material 3 on the inner surface side of the crotch area 2 where the napkin is applied. It is partially provided. This allows the adhesive tape 13 provided on the napkin 10 to be strongly and effectively bonded to the smooth surface portion 4, thereby ensuring that the napkins 10 are stacked and held in the optimal position without any risk of shifting. It can be made stably and can be used comfortably and advantageously. In this case, the smooth surface portion 4 is not provided on the entire surface of the fabric 3a side of the waterproof sheet material 3, but is only partially provided for adhesion of the adhesive tape, so the smooth surface portion 4 is It is possible to avoid direct contact with the skin, or even if it does come into contact, it can be limited to a part of the body that does not have a negative impact on the feel, such as the front of the crotch, and direct contact with the skin remains almost the same as before, with the fabric of the waterproof sheet material. The tactility is good without deteriorating.

Here, the smooth surface portion 4 is provided at a location suitable for adhesion in view of the location and form of adhesive tape in various types of commercially available napkins, and preferably in an appropriate shape. Make the area as small as possible. In this regard, as shown in A to G in FIG. 8, ready-made commercially available sanitary napkins 10 are generally made of a non-woven fabric or the like made by adding a liquid-absorbing agent to a liquid-absorbing fiber material 11 such as cotton. The adhesive tape 13 is attached to one side of the napkin 12 at a position close to one end of the napkin 10 so that the adhesive tape 13 is attached at a position close to the front of the crotch, as shown in Figures A and D. There are several other types that differ slightly in terms of whether the adhesive tape 13 is oriented horizontally or vertically, and whether it has one strip at one location or two strips at two locations. There is.

From this, basically, as in the embodiment shown in FIG.
It is preferable to provide a small rectangular shape, for example, in a portion of the side surface area near the front of the crotch, so that all types of commercially available napkins 10 such as A to G in FIG. 8 can be bonded with the adhesive tape 13. In this case, the strong adhesion on the front side of the crotch can sufficiently stabilize the napkin 10 so that it does not shift, making it convenient for use. In this case, it is preferable that the smooth surface portion 4 has some length margin in the vertical direction so that the adhesive position of the napkin 10 can be slightly adjusted in the front-rear direction according to the user's wishes. Also, especially the 8th
Adhesive tape 13 on the front side and rear side, the front side and the middle part, or in the vertical direction as shown in B, C, E, F and G in the figure.
The smooth surface portion 4 corresponds to the napkin provided with the
are provided at two locations in the surface area of the fabric 3a side of the waterproof sheet material 3, one near the front of the crotch and the other near the rear, as in the embodiment shown in FIG. As in the embodiment, it is also possible to provide a long and thin strip continuously extending from a position near the front of the crotch to a position near the back of the crotch within the surface area of the fabric 3a side of the waterproof sheet material 3. In addition, as in the embodiment shown in FIG.
It may be provided over the entire surface area in the range of ~1/2.

Among these embodiments, in the case shown in FIGS. 2 to 4, the smooth surface portion 4 is positioned in the middle of the width of the surface area on the fabric 3a side of the waterproof sheet material 3. When applying the adhesive, the smooth surface portion 4 may be covered by the napkin 10 and may not come into direct contact with the skin, and the fabric around it may not come into direct contact with the skin other than the napkin 10. 3a, which is particularly advantageous since there is no risk of poor tactility. On the other hand, if the structure is as shown in FIG. 5, the smooth surface portion 4 may partially protrude from the napkin 10 on the periphery and come into contact with the skin. Since it is only a small part, there is almost no problem in this respect.

In this way, the adhesive tape 13 of the napkin 10
The smooth surface portion 4 to achieve a strong adhesion effect may be formed using an appropriate resin such as a natural resin such as rubber or a synthetic resin such as polyurethane, polyester, or vinyl chloride. As illustrated in FIG. 6, a resin sheet 5 made of such a resin is firmly adhered or sewn with an appropriate heat-sensitive or pressure-sensitive adhesive 6 to form a waterproof sheet. It is preferable that it is fixedly attached to the above-mentioned required portions of the surface of the material 3 on the side of the fabric 3a. Also, although not shown, instead of pasting the resin in the form of a resin sheet 5, the resin may be applied to the fabric 3a.
It is also possible to form the smooth surface portion 4 with this resin layer by directly coating the corresponding portion of the side surface. Moreover, without adding resin in this way, as illustrated in FIG. 7, only the fabric layer 3a can be cut out in the form of a cutout hole 7, etc., in the corresponding part of the waterproof sheet material 3. Therefore, the smooth surface portion 4 can be constructed from the remaining waterproof thin film 3b layer such as a resin sheet that is exposed on the front side in the cut portion. Furthermore,
In addition to these configurations, the smooth surface portion 4 may be formed by, for example, a portion of the waterproof sheet material 3 that is turned inside out, i.e., with the fabric 3a on the inside and the waterproof thin film 3b on the front side, although not shown. It is also possible to partially provide a portion where the front and back are reversed, and to form a waterproof thin film with the front side in this portion. This configuration is particularly suitable for the case where the smooth surface portion 4 is provided over the entire surface area in the front side of the crotch, as shown in FIG. In this case, the part of the waterproof thin film that has been turned inside out and which constitutes the smooth surface part is applied as a separate piece onto the corresponding part of the surface of the fabric 3a side of the original waterproof thin film 4, or is folded back as a folded part of the same body as an extension. It can be formed by attaching the waterproof thin film 4 to a part of the original waterproof thin film 4 other than the corresponding part, by adhering it with an adhesive or by sewing, or by splicing it to a part of the original waterproof thin film 4 other than the corresponding part. .

Effects of the present invention As explained above, according to the present invention, when using sanitary shorts, the sanitary napkin is attached to the fabric side surface of the waterproof sheet material on the inner side of the crotch area using pressure-sensitive adhesive tape. The conventional problem of poor adhesion and slippage of the napkin has been solved by applying at least the pressure-sensitive adhesive tape provided on the napkin to the fabric side of the waterproof sheet material on the inner side of the crotch area where the napkin is applied. The problem is solved by a simple additional configuration in which a smooth surface part is partially provided for adhesion of the adhesive tape, which strongly adheres the napkin to the desired position due to the strong and effective adhesion of the adhesive tape on the smooth surface part. It is now possible to stably attach and hold the waterproof sheet material without any risk, and the smooth surface part is not provided on the entire surface of the fabric side of the waterproof sheet material, but is only provided partially for adhesion of the adhesive tape. Therefore, the smooth surface part does not come into direct contact with the skin, or even if it does, it can be limited to a portion of the front groin area that does not have a negative impact on the feel, and direct contact with the skin is different from before. It can be used as a fabric for waterproof sheet materials almost unchanged, and the texture is good without deteriorating, so it is extremely useful in practical terms.
