Description

Side leakage prevention absorption pad and sanitary underpants

Technical Field

The utility model relates to female underpants, in particular to an absorption pad for preventing side leakage and sanitary underpants.

Background

The sanitary underpants refer to the underpants for menstrual period or incontinence, which are elastic bands extending from the crotch part to the back waist of the underpants, reduce the sliding of the sanitary cotton, keep the underpants with air permeability, keep the sanitation to the maximum extent and avoid the damage to the skin caused by sultriness; however, in order to achieve the purpose of absorbing liquid, such underpants are usually provided with an absorbent core, and when the absorbent core is saturated, the absorbed liquid is easy to leak from the edge, so that the underpants having clothes stained by the leakage of menstrual blood or urine often have bad smell because the edge of the absorbent core with a multi-layer structure needs to be fixed by sewing and the threading needle line of the sewing thread generates a leakage hole.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the embodiment of the utility model is to provide an absorption pad for preventing side leakage and sanitary underpants. The occurrence of side leakage can be prevented.

In order to solve the technical problem, an embodiment of the utility model provides an absorption pad capable of preventing side leakage, which comprises a surface layer, an absorption layer, an impermeable layer, a bottom layer and an edge covering strip, wherein the surface layer, the absorption layer, the impermeable layer, the bottom layer and the edge covering strip are sequentially overlapped, the shapes of the layers are consistent, edges of the layers are fixed into an integral structure through a sewing line, the edge covering strip covers the front side and the back side of the edges and covers the sewing line, and the edge covering strip and the edges are fixedly bonded.

Wherein, the impermeable layer is a film compounded on the bottom layer.

Wherein, the absorption layer is one of a towel layer, a high water absorption resin layer, a sponge layer and a cotton layer.

The edge wrapping strip is bonded and fixed with the edge through gluing or is bonded and fixed with the edge through hot-pressing glue.

Wherein the absorbent pad has a crotch region and a hip region of an integrated structure.

Wherein, crotch district both sides are interior arc edge, buttock district both sides edge is for the width change that diminishes gradually.

The embodiment of the utility model also comprises sanitary underpants with the side leakage prevention absorption pad, and an underpants body, wherein the side leakage prevention absorption pad is arranged at the bottom of the underpants body.

The edge of the side leakage prevention absorption pad is consistent with the edge of the crotch area of the underwear body in shape, and is wrapped with the edge of the crotch area of the underwear body through a flanging, and the width of the wrapping at least meets the requirement of covering the edge wrapping strips.

The rear part of the absorption pad extends to the rear waist edge of the underwear body, the rear waist edge is wrapped by a flanging, and the width of the wrapping at least meets the requirement of covering the edge wrapping strip.

Wherein, the edge of the hip area of the absorption pad is fixed with the underwear body by adhesion.

The embodiment of the utility model has the following beneficial effects: the utility model fixes the peripheral edges of each layer of structure of the absorption pad by a sewing machine to form a first separation, so that moisture is not easy to leak out from the edge side, and the edge and the sewing hole are sealed by a stable and reliable edge sealing structure, thereby effectively preventing menses or urine from penetrating through the waterproof layer from sewing threads to seep out, playing a second separation, further coating the edge sealing by flanging on the applied sanitary underpants to form a third separation, and simultaneously avoiding the uncomfortable feeling caused by the friction of the edge sealing on the skin. Compared with the traditional sewing and edge covering process, the traceless edge covering technology can effectively prevent more absorbed blood and urine from seeping out of the sewing thread laying floor. The 'traceless edge covering' process avoids the defect that the sewing needle hole is infected with blood stain and cannot be thoroughly cleaned, and also solves the problem of side leakage of the sewing needle hole due to blood seepage.
