Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called wing type sanitary napkin for absorbing and retaining menstrual blood, and more particularly to a sanitary napkin in an individual bag.

[0002]

2. Description of the Related Art A so-called wing type sanitary napkin having wing portions on both sides of a main body has been known. In this napkin, an adhesive portion for wearing shorts is provided on each of the non-skin contact back surfaces of the main body portion and both wing portions, and each is covered with three release protection pieces separated from each other. Normally, this napkin is obtained by folding both wings toward the back side of the non-skin contact surface and enclosing the napkin in an individual bag.

[0003]

In the napkin enclosed in the individual bag, a part of the release protection piece of the main body is joined to the inner surface of the individual bag, and the protection piece is moved to the individual bag side when removing the napkin. A technique of automatically peeling while leaving is known, for example, from Japanese Utility Model Laid-Open No. 60-79421 and Japanese Utility Model Laid-Open No. 25225/1990. When these known techniques are used for a non-wing type napkin, the napkin taken out of the individual bag has the adhesive portion of the main body already exposed,
It is convenient because it can be directly crimped to shorts.
However, when the known technique is applied to the conventional wing-type napkin, the following is achieved. When the napkin is removed from the individual bag, at the same time as the release protection piece of the main body part is peeled off, the folded wing part is splashed by the protection piece in the direction of opening the fold, but during that time, the wearer has Since the wing part is not involved in the operation of the wing part, for example, supporting the wing part which has been bounced off as it is, the wing part is folded toward the back side of the non-skin contact, so that the wing part moves toward the back side. The wing portion and / or the release protection piece of the wing portion may adhere to the exposed adhesive portion. Therefore, in order to return the wing portion to the normal state, it is not easy to separate from the main body portion, and even if it can be done, the wing portion and / or the main body portion will eventually be damaged, In many cases, the napkin itself cannot be used or the wings cannot be used. When the release protection piece adheres, it is troublesome to peel off the protection piece, if not so much.

[0004] In view of the above, the present invention has been proposed in which the two wing portions are connected to each other by a release protection piece on the surface side of the main body portion so as not to bend toward the back side of the non-skin contact, thereby being enclosed in the individual bag. It is an object of the present invention to solve the problem of a napkin.

[0005]

Means for solving the problems The present invention is as follows to solve the above problems.

The present invention is based on the premise that an absorber is interposed between the surface in contact with the skin and the back surface in contact with the non-skin, and that the absorber extends laterally outward from the opposite edge of the central region of the absorber. A sanitary napkin in an individual bag, comprising a wing portion to be worn, an adhesive portion for wearing shorts provided on each of the back surfaces of the main body portion and the both wing portions, and the adhesive portion covered with a release protection piece.

On this premise, the present invention is characterized in that a part of the main body release protection piece covering the adhesive portion of the main body portion is joined to the inner surface of the individual bag, while the two wing portions are formed along the opposite edge. The wings are folded toward the surface of the main body portion to cover the folded wing portions, and these wing portions are connected to each other.

[0008]

The napkin of the so-called wing type according to the present invention has a release protection piece for the main body joined to the inner surface of the individual bag,
In the removed napkin, the protective piece remains in the individual bag, and the adhesive portion of the main body is exposed. On the other hand, the two wing portions folded to the surface side of the main body portion are connected by the wing release protection piece, do not move unintentionally, and do not adhere to the adhesive portion of the main body portion.
