[Detailed description of the device]

[0001]

[Industrial applications]

  This invention is a so-called wing type sanitary napkin for absorbing and retaining menstrual blood. The present invention relates to the placement of an adhesive portion on a kin, especially its wearing shorts.

[0002]

[Prior art]

  Conventionally, a so-called wing type sanitary nap having wings on both sides of the main body. Kin is known. In this napkin, non-skin contact between the main body and both wings Adhesive parts for wearing shorts are provided on the back side and three pieces separated from each other. A mold release protection piece is coated on each. And usually this napkin is less Both wing parts are folded to the non-skin contact back side and then individually wrapped. It

[0003]

[Problems to be solved by the device]

  When using the above-mentioned known napkin, the wearer attaches each release protection piece to each adhesive part. It is necessary to peel off each release protection piece at once as an example of the procedure. Sometimes. In this case, the folds on both wings are generated on the napkin. Therefore, both wings are bent toward the non-skin contact back side. Therefore, sticking of both wings One and / or both of the parts will adhere to the adhesive part of the main part and Once they have been glued together, both wings will be restored to their normal state. I tried to peel it off, but I couldn't peel it off easily However, after all, those parts are damaged or the adhesive strength is significantly reduced, It is not uncommon for the napkin itself to become unusable.

[0004]   Even if the release protection pieces are peeled off at the same time, this device is designed so that both wings In order to prevent the adhesive part in the main part from adhering to the adhesive part in The issue is how to arrange the parts.

[0005]

[Means for Solving the Problems]

  The present invention for solving the above-mentioned problems is directed to a case in which a skin contact surface and a non-skin contact back surface are absorbed. The main body portion in which the absorber is interposed and the lateral edge outwardly extend from the opposing edges of the central region of the absorber. The main body part and the non-skin-contacting back surfaces of the both wing parts. Adhesive parts for each piece are provided, and these adhesive parts are covered with release protective pieces. It is premised on a scientific napkin.

[0006]   In the structure of the said premise, the said adhesive part in the said main part is the said both wing part. It is not located in the region connecting the both adhesive parts in.

[0007]   In the embodiment of the present invention, the release protection piece covers the whole of the adhesive parts. Formed from a series of sheets of size.

[0008]

[Action]

  In the napkin according to the present invention having the above configuration, each of the main body portion and the wing portion is After peeling off each release protective piece from the adhesive section at once, wear show at each adhesive section It can be attached to the crotch pad of the shoe. In this case, the two wings of the napkin Even if both wings bend due to the fold line to the side of the non-skin contact back side, The non-skin contact back surface of the main body part where the adhesive part of , Adhesive parts of both wing parts are bonded to the area connecting both adhesive parts of both wing parts. There is no end.

[0009]

【Example】

  An example of a napkin according to the present invention will be described with reference to the drawings. It is Ri.

[0010]   As shown in FIGS. 1 and 2, the napkin has a non-skin contact surface 1 (see FIG. 4). A main body portion 3 having a contact surface 2 and both wings (wing) portions 4 facing each other on both sides thereof. It consists of and. Except for the central region of the non-skin contact back surface 2 of the main body portion 3, Before and after, two adhesive parts 5 are provided in parallel. Non-skin contact back of both wing parts 4 Adhesive portions 6 are provided one by one on the surface on the side of the surface 2.

[0011]   It should be noted here that the front and rear adhesive parts 5 in the main body part 3 are That is, it is not located in the area 7 connecting the both adhesive portions 6 in. As shown in the figure, the distance between the inner ends of both adhesive parts 5 facing the front and back of the main body part 3 is It is preferably larger than the width of zone 7.

[0012]   Each of the adhesive parts 5 and 6 is covered with a release protection piece 8. The release protection piece 8 has an adhesive portion 5 The sheet portion 8a for the adhesive and the sheet portion 8b for the adhesive portion 6 are adhered to each other. Agent 9 (see FIG. 4) is bound in series. Of course, the release protection piece 8 is a single piece. Can be made.

[0013]   Although not shown in the figure, a large number of embosses are applied to the area 7 and its vicinity and By applying a recon resin, the adhesiveness of the adhesive parts 5 and 6, especially the adhesive part 6, is reduced. You may let me.

[0014]   As shown in FIG. 3, at least the napkin on which the release protection piece 8 is attached to a predetermined portion is required. After folding both wing portions 4 toward the non-skin-contacting back surface 2 side of the main body portion 3, they are individually wrapped. It will be.

[0015]   As shown in FIG. 4, the napkin is a liquid-permeable topsheet 1 forming a skin-contacting surface 1. 0, a liquid-impervious backsheet 11 forming a non-skin-contacting backside 2, and their central regions And an absorbent body 12 interposed between them. As is well known, these configurations Belongs to the public.

[0016]   A hot-melt type pressure-sensitive adhesive is used for the adhesive parts 5 and 6, and a release protective piece 8 is used. Is a silicone resin on the inner surface of the kraft paper at least in contact with the adhesive parts 5 and 6. The applied ones can be used respectively. In addition, the surface sheet 10 Non-woven fiber, porous plastic film, plastic sheet for back sheet 11 Film, waterproof non-woven fabric, absorbent body 12 is crushed pulp with highly absorbent polymer -A mixture of particles can be used.

[0017]   When using the napkin, for example, the front portion of the first portion 8a of the release protection piece 8 When grasping and pulling apart, the second part 8b and the rear part of the first part 8a are continuously peeled off in this order.

[Effect of device]

  According to the napkin according to the present invention having the above-described configuration, both wings formed on the napkin Even if both wing parts are bent to the non-skin contact back side due to the folding line of the part, Does the adhesive part on the wing part adhere to the adhesive part on the main part? , The wings will be damaged and the adhesive strength will be significantly reduced. Not only will you not be unable to use it, but also menstrual blood will flow rapidly. If there is a risk of it coming out, it can be quickly worn.

[0019]   As mentioned above, due to the folding lines of the wings on the napkin, Non-skin contact Even when bent to the back side, the adhesive parts of both wings contact the adhesive part of the main part. Since it will not be worn, the release protection piece of each adhesive part can be peeled off at once. Can be formed of a series of sheets so that Also, when it was formed in that way In this case, the napkin can be worn more quickly, which is extremely convenient.
