Embodiment Construction

[0018] Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

[0019] As mentioned above, the present invention relates to absorbent articles 1, such as sanitary napkins, pantiliners, incontinence pads or diapers. Preferably, the absorbent article 1 is a sanitary napkin. These items are commonly used to collect and store body exudates such as urine, feces or menstrual fluid. The absorbent article 1 is preferably disposable, ie it is used only once and then discarded instead of being washed and used again.

[0020] figure 1 A plan view showing a first embodiment of the absorbent article 1 according to the present invention. figure 1 The absorbent article 1 shown in is a sanitary napkin. As shown, article 1 has a transverse direction x, a longitudinal direction y and a longitudinal centerline A. As shown in FIG. The total length of the article 1 in the longitudinal direction is the length b. The article 1 also has ...

Abstract

The present invention relates to an absorbent article (1 ) having front, crotch and rear portions (2, 3, 4) and an absorbent core (6) of unitary construction. The core has a first region (12) comprising two legs (15, 16) extending in the longitudinal direction of the article over at least parts of the crotch portion towards endings (17,18) in the rear portion. A maximum distance (a-1) between facing sides (19, 20) of the legs in the transverse direction is, in the crotch portion, located at a position in the longitudinal direction corresponding to a crotch point (21 ). Furthermore, the facing sides of the legs converge backwards such that a distance (ax) between them is reduced from the maximum distance (a1) to a minimum distance (82) in the rear portion. In addition, the core comprises a second region (24) surrounding the first region and the average density of the core is lower in the second region than in the first region.

Description

technical field [0001] The present invention relates to absorbent articles, such as sanitary napkins, pantiliners, incontinence pads or diapers, which are designed to take a specific form while in use and provide increased security against leakage. Certain regions of the article are less dense than others, allowing the article to take a desired shape and minimizing problems associated with movement of the article out of place on the user's body. Background technique [0002] The main requirements of absorbent articles such as sanitary napkins, panty liners, incontinence pads or diapers include, in addition to good absorption properties, good fit and leakage safety. Various approaches have been taken in the design and manufacture of absorbent articles so that during use the absorbent article effectively follows the contours of the user's body and does not move out of position.
