Abstract

Disposable garments such as disposable diaper or training pants comprising an absorbent panel sandwiched between a fluid-permeable, stretchable topsheet and a fluid-impermeable, stretchable backsheet, wherein said panel is bonded to said topsheet at dot-like locations at given intervals but not bonded to said backsheet.

DISPOSABLE ABSORBENT GARMENTS

BACKGROUND OF THE INVENTION
The present invention relates to disposable absorbent garments, such as disposable diaper or training pants, comprising an absorbent panel sandwiched between a fluid-permeable topsheet and a fluid--impermeable backsheet.
The absorbent panel, for example, in disposable diaper has usually been fixedly bonded to the respective inner surfaces of the top- and backsheets with a plurality of stripe-like adhesive lines applied on said respective inner surfaces.
. For example, in the disposable training pants having the waist-line previously connected t:ogether in the form of a closed loop, it is required for the top- and backsheets to maintain their original stretchabilit:y in view of handling easiness for wearing and taking off dS well as wearing fitness. However, the arrangement that the absorbent panel is bonded to both the top- and backsheets as in the case of the above-mentioned diaper has inconveniently obstructed the stretchability thereof over a wide range and thus has been unsatisfactory for said easiness for wearing and taking off .as well as said wearing fitness.
Accordingly, it is an object of the present invention to provide disposable absorbent garments using stretchable 2 ~

materials as the top- and backsheets and comprising the absorbent panel fastened in such a manner that said panel can not move at hazard and the stretchability of said top-and backsheets, particularly, of said backsheet can be adequately maintained.

SUMM~RY OF THE INVENTION
The object set forth above is achieved, in accordance with the present invention by absorbent garments comprising an absorbent panel sandwiched between a fluid-permeable, stretchable topsheet and a fluid-impermeable, stretchable backsheet, characterized by that said panel is bonded to said topsheet at dot-like locations at given intervals but not bonded to said backsheet.
In one preferred embodiment, said topsheet comprises fluid-permeable, stretchable non-woven fabric while said backsheet comprises fluid-permeable, stretchable non-woven and fluid-impermeable, stretchable barrier sheet such as plastic or rubber film, and said panel comprises a mixture of fluffy pulp, superabsorbent polymer powder and thermoplastic fibres in which said fibres are welded together and thereby the entire mixture is compression-molded in the direction of its thickness.
In another preferred embodiment, said non-woven fabric of said backsheet is bonded to said :barrier sheet at dot-~3~

like locations at given intervals.
One of the important features of the present inventionsuch that, as has been mentioned above, said panel is not bonded to said backsheet is advantageous in that said backsheet is free to be stretchable without any restriction by sai.d panel so as to press said panel against the wearer's body with a good fitness.
The other important feature of the present invention such that said panel is bonded to said topsheet at dot-like locations at given intervals not only provides a more comfortable touch for the wearer's skin than the conventional garments having much more bonded locations but also allows liquid excretions to be rapidly and effectively absorbed from said topsheet into said panel.
Furthermore, the manner of bonding cooperates with the intrinsic function of said backsheet to reliably prevent said panel from moving at hazard.

BRIEF ~ESCRIPTION OF TH~ DRAWINGS
Training pants constructed as an embodiment o~ the present i.nvention is illustrated by l:he accompanying drawing, in which:
Fig. 1 is a perspective view of the training pants;
Fig. 2 is an exploded perspective view of the same;
Fig. 3 is a plan view showing the inner surface of the 2~3~
topsheet; and Fi~. ~ is a sectional view showing the absorbent panel covered with the top- and backsheets.

PREFE~RED EMBODIMENTS OF THE INVENTION
The invention will be described by way of embodiments in reference wi~h the accompanying drawings.
Fig. 1 is a perspective view of training pants 1 having a pair of leg-holes 2 and a waist-hole 3 provided with elastic members 4, 5, respectively.
Fig. 2 is an exploded perspective view of the pants 1 comprising a fluid-permeable, stretchable topsheet 6, a fluid-impermeable, stretchable backsheet 7, an absorbent panel 8 and said elastic members ~, 5 for the legs and the waist, respectively.
The topsheet 6 comprises a fluid-permeable, stretchable non-woven fabric. The backshee-t 7 comprises a fluid-permeable, stretchable non-woven ~abrlc 7a and a fluid-impermeable, stretchable barriex sheet such as plastic or rubber ~ilm 7b. The panel 8 is in so-called hourglass shape and comprises a mixture 2 flu~fy pulp, superabsorbent polymer powcler and thermoplastic fibres in which said fibres are welded together and thereby the entire mixture is compression-molded in the direction of its thickness so as to have a semi-rigidity.

2~9~

Opposite side edges of a crotch zone 1~ defined between front and rear sections 10, 11 of the top- and backsheets 6, 7 are formed with no-tched edges 13 to form the respective leg-holes 2. These notched edges 13 and a waist edge 14 are provided with the elastic members 4, 5, respectively. The elastic member 4 for leg-holes consists of a first submernber 4A and a second submember AB. The first and second submembers 4A, 4B intersect each other at points l~ing adjacent their opposite ends, defini:ng intersections adjacent middle points on the respective notched edges 13.
~ Sections 4A1, 4B1 of these submembers 4A, 4B extending from the respecti~e intersections to the associated outer ends are bonded to the inner surface(s) of the top- and/or backsheets along the respective notched edges 13 with adhesive and intermediate sections 4A2, 4B2 Of said submembers 4A, 4B are bonded to none of the components but merely positioned on the central underside of the panel ~.
The elastic member 5 for the waist-hole is bonded to the inner surface (5) of the top-- and/or backsheet along the waist edge 14 with hot melt type adhesive (not shown).
Outer peripheral edges of the top- and backsheets 6, 7 may be bonded to each other by bonding means such as said adhesive or welding (including ultrasonic welding).
Fig. 3 is a plan view showing the inner surface of the topsheet 6. The panel 8 is position.ed at a zone 16 2 ~
surrounded by chain line 15 on the inner surface of the topsheet 6. As shown by Fig. 4, the zone 16 of the topsheet 6 is intermittently bonded to the top surface of said panel 8 by dot-like bonding means 17 disposed at relative1y large intervals so as to prevent said zone 16 from floating off from the top surface of the panel 8 and thereby from obstructing inward transmission of li~uid excretions -through said zone 16 and to prevent said panel from moving at hazard. The bonding means 17 also may be selected from said various bonding means.
Preferably, the non-woven fabric 7a of the backsheet 7 and the sheet 7b are intermittently bonded to each other by dot-like said bonding means. If desired, said non-woven fabric 7a may be intermittently bonded, in the panel absent zone, to both the topsheet 6 and the sheet 7b with which said non-woven fabric 7a is in direcl, contact, by said dot-like bonding means.
A laminate thus assembled as disposable training pants may be longitudinally folded in two along the middle line thereof and then the opposite side edges 9 may be bonded together by said bonding means to form the completed pants 1 as illustrated by Fig. 1. It should be understood that the present invention may be embodied also as disposable diaper of open type including adhesive tape used to loop the waist line.
