Abstract

The utility model provides a side-leak-proof sanitary towel with a vertical edge for women. One the basis of the existing used sanitary towel, the woodpulp napkin of which is clamped between an upper and a lower composite layers, both sides of the woodpulp napkin are additionally provided with elastic, ventilating and impermeable sponge strips. After the sponge strips are stretched, both ends and outer margins are glued on the upper and the lower composite layers through thermal pressure. When the utility model is used, after protective wings are folded downwards, the sponge strips are erected, shrunk and anastomosed with the inner sides of thighs for playing the action of preventing side leak. The utility model has the advantages of convenient use, comfort, and sanitation and thoroughly solves the problem of the side leak.

Description

A kind of side leakage preventing sanitary towel that upright edge is arranged

This utility model belongs to the articles for daily use, and it relates to a kind of women use sanitary napkin.

The present sanitary towel that uses, the surface is the plane, promptly accompany one deck wood pulp cotton structure in the middle of the composite bed up and down, last composite bed is non-woven fabrics (outward) and suction cotton paper (lining) layer, following composite bed is macromolecule water uptake paper (lining) and PE film (outward) layer, in use, make menses, make troubles to use to the both sides spill and leakage because absorption speed has limited the absorption of sanitary towel.Though people have carried out various improvement on this basis, make the both sides projection, as utilize the rubber reinforcement methods such as both sides non-woven fabrics that stretched tight, because therefore the gap problem can't solve boss and adhere to human body the time prevents that the side leakage effect is still undesirable.

The purpose of this utility model is to provide a kind of both sides that upright edge is arranged, and adheres to closely seamless sanitary towel with human body.

The purpose of this utility model is achieved in that be added with one respectively in the wood pulp cotton both sides resilient, the sponge strip of permeable watertight, after sponge strip is stretched with two ends and outer rim heat pressure adhesive on composite bed up and down.

Describe below in conjunction with accompanying drawing.

Fig. 1 is this utility model planar structure sketch map.

Fig. 2 is to use the longitudinal profile structural representation of state.

1 is sponge strip among the figure, its bend partly is and composite bed heat pressure adhesive part up and down, the 2nd, wings of sanitary towel, opisthotonos during use, the 3rd, the district that attracts deposit of sanitary towel, the 4th, following composite bed, form by macromolecule water uptake paper (lining) and film (outward), 5 is last composite bed, is made up of non-woven fabrics (outward) and suction cotton paper, and 6 is wood pulp cotton.

Since after sponge strip 1 is to be stretched when producing with two ends and outer rim heat pressure adhesive on composite bed 4,5 up and down, therefore in use after flap is rolled over for 2 times, sponge strip erects and shrinks, and the sanitary towel rear and front end is upturned, form the ship shape, and sponge strip similarly is two sides of a ship of ship.Owing to the inherent shape of sanitary towel itself, add the elasticity and the flexibility of sponge strip, make when sanitary towel in use becomes the U type that sponge strip still can closely coincide at femoribus internus, promptly adheres to naturally with the human body external form, does not stay the slit.When blood volume is maximum, because the last composite bed seepage speed in the district 3 that attracts deposit of sanitary towel and the absorption speed of wood pulp cotton have limited moment a large amount of menses are absorbed, the part menses are attracted deposit district and the gap of human body to the both sides overflow along sanitary towel, this moment since two edge-on edges (being sponge strip) be higher than sanitary towel attract deposit the district and with the human body tight connecting, again since the sponge strip outer rim be and composite bed heat pressure adhesive all-in-one-piece up and down, (being the A part of Fig. 2), therefore, having blocked the overflow menses leaks outside, make its backflow and be absorbed, thoroughly solved the side leakage phenomenon.

In order to improve the assimilation effect in the district 3 that attracts deposit, this utility model will be gone up the nonwoven layer structure of composite bed 5 and improve, and change single-layer nonwoven the two-layer compound layer of non-woven fabrics and PE film into, and be equipped with many trumpet type apertures in the above, menses can only unidirectional water conservancy diversion, can not overflow.

In order to reduce cost, easy to use, the release paper that this utility model will descend composite bed back-protective fixing glue unites two into one with the wrapping paper of packing sanitary towel, promptly packs little generation and plays the packing effect and play the release paper effect again.

Because this utility model has adopted sponge strip to stand the edge, has overcome the side leakage problem of existing sanitary towel, uses more comfortable, convenient, healthy, safety.
