Problems solved by technology

[0005] Second, the process of coating adhesive parts with a single adhesive strip is complex and requires constant adjustment and intervention of the coating machine in order to make it work satisfactorily
Although in practice such an area does not interfere with the proper attachment of the sanitary napkin to the panty, the consequence is a perceived low quality which can affect confidence in using the product
[0006] Third, when due to these problems when it is applied, the adhesive can be displaced with respect to the hygienic
Such displacement creates air bubbles when the protective film of adhesive is removed, seriously compromising the ability of the sanitary napkin to adhere to the panty and its efficacy

The center point of the semicircle defined by the secondary ridges lies substantially on the plane defined by the frame 3 .

[0029] The second variant of the personal sanitary napkin of the present invention also has a substantially flat, elongated frame 3', followed by substantially the same spine as described in the preceding paragraph. However, the main spine of the frame 3' has a generally trapezoidal intermediate portion protruding outwards relative to the spine, thereby forming two additional curvilinear surfaces 5, also called projections 5.

[0030] Frames 3' and 3 each include an absorbent core 2 co...

Abstract

Disclosed is a intimate napkin, comprises a substantially planar and elongated frame which has a impervious material outer layer, an absorbing core inserted into the napkin and a adhesive layer on a pervious material layer, the characters is the adhesive layer virtually comprises at least five seperate bond. The napkin according to the invention is provided to prevent from being detached from the user's underwear while allowing a shear action, the napkin holds a certain fixed ability with less bond and can be coated by several pipe, the production process of the napkin is easy and is more reliable than the process using a single wide bond strip. The napkin of the invention has a more aesthetically elaborated appearance, which promote the selling.
