[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.

[0002]

2. Description of the Related Art A so-called wing type sanitary napkin having wings 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 folded separately on both wing portions to the side of the non-skin contact back surface, and is individually packaged.

[0003]

When using the known napkin, the wearer needs to peel off each release protection piece. As an example of the procedure, first, peel off only the release protection piece of the main body part, fix the napkin to shorts,
Thereafter, the release protection pieces of both wing portions may be peeled off.
In this case, since the napkin is creased by folding both wings, the wings are bent toward the non-skin contact back side. As a result, the two wing portions or the release protection pieces adhere to the adhesive portion of the main body portion, and when the two wing portions are separated from the main body portion to return the wing portions to a normal state, the main body portion and / or the wing portion are damaged, and the napkin is damaged. It is not uncommon that the device itself cannot be used. When the release protection piece of the wing part is adhered, the peeling operation is troublesome, if not always.

[0004] In view of the above, the present invention proposes that the napkin is connected to the shorts by connecting them at the side of the skin contact surface so that the both wings do not bend toward the non-skin contact back side. The problem is to solve the problem in napkins.

[0005]

Means for solving the problem The present invention provides means for solving the above problems as follows.

The sanitary napkin according to the present invention is based on the premise that the absorbent body is interposed between the surface in contact with the skin and the back surface in non-skin contact and the opposite edge of the central region of the absorbent body. An adhesive portion for wearing shorts is provided on each of the back surfaces of the main body portion and both wing portions, and the adhesive portions are covered with a release protection piece.

On this assumption, the present invention is characterized in that the wing portions are folded along the opposed edges toward the surface of the main body portion, and the wing separation portions cover the adhesive portions of the folded wing portions. That is, both wing portions are connected by the mold protection piece.

[0008] The release protection piece connecting the two wing parts is left and right.
It can be split or separated, and the connection between the two wings can be
Can be.

[0009]

In the napkin according to the invention, the release protection piece for the main body is peeled off, and the adhesive portion of the main body is pressure-bonded to the inside of the crotch shorts. Bend to the outside of the shorts crotch and crimp. Since the two wing portions are connected by the protection piece and do not move unintentionally, they do not adhere to the adhesive portion of the main body after the protection piece is peeled off. After crimping the main body portion to the shorts, the protection piece is divided or separated into right and left, and each wing portion can separate the protection piece separately.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the sanitary napkin according to the present invention will be described below with reference to the accompanying drawings.

FIGS. 1A and 1B are plan views of a sanitary napkin 1, wherein FIG. 1A shows a skin contact surface side and FIG. 1B shows a non-skin contact back surface side. The napkin 1 includes a liquid-permeable top sheet 2 forming a skin-contacting surface, a liquid-impermeable backing sheet 3 forming a non-skin-contacting back surface, and an absorber 4 interposed between these two sheets 2 and 3. And left and right wing portions 10 extending laterally outward from the opposing edge 6 in the central area of the main body portion 5. The back sheet 3 of the main body portion 5 has two adhesive application areas 11 extending in the longitudinal direction, and each wing portion 1
The back sheet 3 of No. 0 has an adhesive application area 12. The wing portions 10 are folded toward the topsheet 2 along the opposing edge 6, and one wing release protection piece 16 connecting the wing portions 10 covers the left and right adhesive application areas 12. Such a connection by the protective piece 16 is such that the protective piece 16
Is maintained by bonding to it. The pressure-sensitive adhesive application area 11 is covered with a single main body release protection piece 15.

The procedure for wearing the napkin 1 thus constructed is as follows. First, the main body release protection piece 15
Is peeled off, and the napkin 1 is crimped to the inside of the crotch part of the shorts (not shown). After that, the wing release protection piece 16 is peeled off, and each wing portion 10 is turned outward and crimped to the outside of the crotch portion of the shorts. According to this procedure, the application area 11
Since the protective pieces 16 connecting the left and right wing portions 10 are not peeled off until the wing portions 10 are pressed on the shorts, there is no possibility that the wing portions 10 adhere to the application area 11 at all. As is apparent from this procedure, despite the fact that the napkin 1 is of the wing type, the operation until crimping to the inside of the shorts crotch is the same as the operation of the non-wing type, and the wearer can check the presence of the wings. This has the advantage that the wear operation can be performed without bothering the user.

FIG. 2 shows a napkin 1 similar to that shown in FIG.
FIG. 3 is a plan view showing an example of a mode of a wing part release protection piece 16. The protection piece 16 is provided between the left and right wing portions 10 in the second perforation.
0, and notches 21 provided at both ends thereof, and can be divided into left and right protection pieces 16A and 16B by tearing at perforations 20 as necessary. The notch 21 is a guide for ensuring that the tearing can be performed according to the perforations 20.

FIG. 3 is a view similar to FIG.
It is a top view which illustrates the 6th aspect. The protection piece 16 includes left and right separate protection pieces 16A and 16B. The protection pieces 16A and 16B overlap between the two wing portions 10 and are joined in the adhesive application area 22. The protection piece 16 is a protection piece 1
When the inner edge 23 of 6A is gripped and pulled in the direction of the outer edge 24, the portion of the adhesive applied area 22 is peeled off and can be divided into protective pieces 16A and 16B.
When the outer edge 24 or 25 of 16B is pinched, the protection piece 16 can be peeled off without being divided. These peelings are caused in each of the adhesive application areas 12, 2
It is possible by adjusting the balance of the adhesive strength of No. 2.

As illustrated in FIGS. 2 and 3, if the wing release protection piece 16 can be divided, the wearer can peel off the protection pieces 16A and 16B for each of the left and right wing portions 10 and shorts. Since the protection pieces 16 were simultaneously peeled off from both wing portions 10 because the pressure bonding to
In this case, it is possible to avoid a situation in which one of the wing portions 10 is bonded to an unexpected place while one of the wing portions 10 is being pressed on the shorts. However, if the wearer prefers to peel off the protective pieces 16A, 16B of the wing portions 10 at the same time, this is possible as described above.

The napkin 1 is tightly joined at a portion where the front and back sheets 2 and 3 extend around the absorber 4. The wing portion 10 includes front and back sheets 2 extending from the main body portion 5.

When folding the napkin 1 in the longitudinal direction and enclosing it in an individual bag,
The two wing parts 10 are connected with the protection piece 16 and then folded.

[0017]

The so-called wing-type napkin according to the present invention folds the left and right wing portions toward the surface of the main body portion and connects the wing portions to each other. It does not happen that the napkin does not move easily and adheres to the adhesive portion of the main body portion, which makes the processing operation cumbersome, and that the napkin cannot be used due to the damage of the main body portion and / or the wing portion due to the operation.
