Embodiment Construction

[0040] figure 1 and 2 The pant diaper 1 shown is designed to enclose the lower torso of the wearer like conventional underwear. exist figure 1 In, the diaper 1 is shown from the inside, that is, from the side facing the wearer when the article is put on, and in figure 2 1, the diaper 1 is shown from the outside or garment-facing side, which is the side that faces away from the wearer when the diaper is donned.

[0041] Diaper 1 in figure 1 is shown in a flat condition with open side seams and with any pre-stretched elastic stretched out. exist figure 2 In , the diaper 1 is shown in three dimensions, as it would be when worn by a user.

[0042] The diaper 1 has a front panel 2, a back panel 3 and a crotch panel 4 extending between the front and back panels 2,3 and being relatively narrow compared to the front and back panels 2,3. The front and back panels 2, 3 are arranged to cover the wearer's buttocks and extend over the wearer's stomach and back to encircle the lowe...

Abstract

A pant-type absorbent article (1) comprising a chassis structure (6) comprising a front panel (2) having a front end edge (8) and first and second side edges, a back panel (3) having a back end edge (8) and first and second side edges (9) and a crotch panel (4) arranged between the front and back panels (2, 3) at least one of said front and back panels (2, 3) comprising an elastic nonwoven / film laminate, and a core (22) being integrated with the chassis structure (6), the first and second side edges (9) of the front panel (2) being joined by side seams (10) to the corresponding first and second side edges (9) of the back panel (3). Each side seam (10) is formed at least in part in a weldable connecting member (13), the connecting member (13) comprising a first part (27) being secured to a side edge (9) on the front panel (2) and a second part (28) being secured to a corresponding side edge (9) on the back panel (3), said first and second parts (27, 28) of said connecting member (13) being joined by thermowelding to form said side seam (10). The invention also concerns a process for the production of a pant-type absorbent article.

Description

technical field [0001] The present invention relates to a pant-type absorbent article comprising a chassis structure comprising a front panel having a front end edge and first and second side edges, a rear end edge and The back panel of the first and second side edges, and the crotch panel disposed between the front panel and the back panel, the first and second side edges of the front panel are connected to the corresponding first and second side edges of the back panel by side seams The two side edges meet. Background technique [0002] Pant-type absorbent articles typically comprise a pant-type chassis structure and an absorbent core component integrally formed with the chassis. The main goal when designing pant items is to make them look as close as possible to regular underwear. Accordingly, absorbent articles such as pant diapers, sanitary pants, and drop-waisted pants are designed to fit the wearer comfortably and snugly. There is also a need for such articles to b...
