Embodiment Construction
[0042] Various aspects of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. However, the embodiments disclosed herein may be embodied in many different forms and should not be construed as limited to the aspects set forth herein.
[0043] First refer to figure 1 , which shows a top view of an absorbent article 1 in the form of a baby diaper. absorbent article 1 in figure 1 shown in the unfolded and flat state. Additionally, the absorbent article 1 is based on an absorbent structure for absorbing body exudates from the wearer, thereby providing the wearer with a dry and comfortable fit.
[0044] like figure 1 As shown, the absorbent article 1 comprises a liquid permeable topsheet 3, a liquid impermeable backsheet 4, and an absorbent core 5 sandwiched between the topsheet 3 and the backsheet 4. The topsheet 3 is arranged on the surface of the absorbent article 1 , ie on the side facing the wearer, while the backshee...

Abstract
The present disclosure relates to an absorbent article (1) comprising an absorbent core (5) sandwiched between a liquid-permeable topsheet (3) and a liquid-impermeable backsheet (4), the article (1) along the A longitudinal axis (y1) and a transverse axis (x1) extending in a vertical direction relative to the longitudinal axis (y1) are arranged, and the article (1) defines a front (6), a rear (7) and a crotch ( 8), wherein the absorbent core (5) comprises an absorbent member (5a, 5b, 5c) surrounded by a core sleeve (11, 12) comprising an upper side (11) and a lower side (12), and a sealing means (9, 10), said sealing means for engaging said upper and lower sides (11, 12) and comprising in said crotch portion (8) defining a first channel seal width (w1) and a second channel seal Two channel seals (9, 10) of width (w2). The channel seals (9, 10) are formed by a thermal and / or mechanical weld pattern (23) comprising a plurality of welds (24) in a first row (23a) along the longitudinal axis (y1) and Arranged in the form of a second row (23b) along the longitudinal axis (y1), wherein each weld point (24) of the first row (23a) extends along the first axis (25) and each of the second row (23b) The welding points (24) extend along a second axis (26), the first axis (25) and the second axis (26) defining a first angle (α1) with respect to each other.
Description
technical field [0001] The present disclosure relates to an absorbent article comprising an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet. The present invention also relates to an absorbent core for an absorbent article, and to a method for manufacturing an absorbent article of the type described above. Background technique [0002] Wearable and disposable absorbent articles, such as in the form of diapers, incontinence garments, feminine garments, and the like, are well known. Such articles are used to absorb, distribute and store various types of body exudates, while providing the wearer with a high level of comfort and dryness during use. [0003] Conventional disposable absorbent articles in the form of diapers are typically designed with an absorbent core sandwiched between a topsheet and a backsheet. The article is arranged along a longitudinal axis and along a transverse axis extending in a perpendicular direction r...
