Description

[Detailed Description of the Invention] The present invention relates to a sanitary napkin characterized by the structure of the absorbent body.

In the past, various attempts have been made to improve the form in order to improve the fit and fit when worn. A sanitary napkin that satisfies the fit and adhesion has not yet appeared.

In view of the above-mentioned circumstances, the purpose of the present invention is to provide a product that can be mass-produced at low cost without changing the basic form and that can satisfy the fit and fit when worn. In order to achieve this, the gist of the present invention is to provide at least an absorbent body 2 made of pulverized pulp, a water-impermeable sheet 3 disposed on the lower surface of the absorbent body 2, and a water-permeable sheet covering a laminate of these. In the sanitary napkin comprising: Width W between 6a
1 is 25 to 4 Qm/m, and the width W2 between each of the compression recesses 6 and each outer end of the absorbent body 2 is 5 to 15 rrlIm.

The present invention will be further explained based on the illustrated embodiments as follows.

The napkin 1 consists of an absorbent body 2, an impermeable sheet 3 rolled up from the lower surface of the absorbent body 3 to both ends in the lateral direction, and a laminate of these sheets wrapped horizontally and both ends 4 in the longitudinal direction of the absorbent body 2 are covered with hot pressure (melting). It looks great from the water permeable sheet 5 that is attached.

The absorbent body 2 is made of pulverized pulp.

Compression recesses 6 are provided near both ends in the horizontal direction of the upper surface of the absorbent body 2, reaching near both ends in the longitudinal direction and having a wide portion 6a at the center.

The compressed recess 6 can be provided by compressing the upper surface of the absorbent core 2 with a pressing mold having the same shape as the recess.

The width W□ between both store width parts 6a of the compression recess 6 is 25 to 40 m.
/m, the width W2 between each compression recess 6 and each outer end of the absorbent body 2 in the lateral direction is 5 to 15 m.The width W2 of 7 m maintains the fit and adhesion of the napkin 1 to the female private parts when worn. preferred above.

Further, it is preferable that both longitudinal ends 7 of the upper surface of the absorbent body 2 are made to become gradually thinner toward the outer ends.

In addition, although the absorber 2 in the illustrated example is made of only pulverized pulp,
Another absorbent material such as absorbent paper may be arranged on the lower surface of the absorbent material, and a water-permeable web or sheet as thin as not to reduce the effect of the squeezing recesses 6, which will be described later, may be arranged on the upper surface of the absorbent material. be.

The napkin according to the present invention is used with the upper surface of the napkin 1, which is the side where the compression recess 6 is located, in contact with the female private parts. In addition, the napkin 1 is pressed against the inner side of the thigh and bent through the compression recess 6.

Therefore, the state in which the napkin 1 is worn is in close contact with the woman's private parts.

In addition, in the squeezed recess 6, the pulverized pulp is denser than in the unpressed part, and the degree of fiber bonding is higher, so menstrual blood in the recess is quickly absorbed and flows vertically along the recess. The flow is diffused in the direction.

This prevents menstrual blood from leaking sideways.

Some conventional napkins have compressed recesses in the vertical direction of the absorbent body that absorbs the crushed pulp, but these are simply provided with several compressed recesses in the vertical direction, and the wide part 6a of the present invention Since no equivalent is provided, the conformal adhesion is poor and undesirable.

In addition, some napkins have recesses at both ends of the center to improve the adhesion, but when the recesses are formed, the absorbent material is reduced accordingly, and the menstrual blood absorption capacity and range are also reduced. This is undesirable as it causes leakage of menstrual blood.
