Abstract

The utility model provides an anti-leakage sanitary napkin that can prevent menses from leaking in all directions, which comprises a penetrative surface layer, an impervious bottom layer and an absorption core set between the penetrative surface layer and the impervious bottom layer, wherein the penetrative surface layer, the impervious bottom layer and the absorption core are mutually stuck together as a whole by a hot melt adhesive; a leak-proof layer is set above the penetrative surface layer; the four external sides of the leak-proof layer are connected along the penetrative surface layerfixedly; middle of the leak-proof layer is provided with a hole so that menses can contact with the penetrative surface layer without any hindrance; two lateral sides of the hole are provided with a folding part separately along the nearby leak-proof layer; each of the folding part extends along longitudinal direction of the sanitary napkin, and a resilient is set above the folding part that extends along longitudinal component of the sanitary napkin.

Description

A kind of leakproof sanitary towel

Technical field

This utility model relates to a kind of leakproof sanitary towel, and it belongs to the disposable adsorption object field.

Background technology

Sanitary towel has been known, it generally comprises liquid permeability surface layer such as hydrophilic nonwoven fabrics or making hole film, opaque liquid bottom such as ventilated membrane or cast film and be located at the liquid permeability surface layer and the opaque liquid bottom between absorbent cores such as absorbent paper, dust-free paper, paper pulp fiber and super water-absorbing resins mixture etc., pass through the melt viscosity integrator between each layer and the layer, in use fix for better making sanitary towel, sanitary towel generally is provided with two flaps, described flap is made of to local extension the in horizontal both sides respectively the longitudinal middle part of liquid permeability surface layer and opaque liquid bottom, the bottom surface of described flap is provided with flap glue, this flap glue outer side covers has release paper to prevent that it is contaminated before use or destroys, the bottom surface of described opaque liquid bottom is provided with fixedly adhesive tape, and described fixedly adhesive tape surface also is coated with release paper and prevents that it is contaminated before use.Its surface layer of existing in addition sanitary towel generally is provided with symmetrical anti-side leakage edge, described each anti-side leakage edge is generally formed by refusing water non-woven fabrics parcel elasticity elastic such as elastomeric polyurethane fiber band, the described vertical two ends of refusing the water non-woven fabrics and the outside be along being fixedly arranged on the liquid permeability surface layer, make sanitary towel in use two anti-side leakage edge upwards erect and prevent that menses from leaking to both sides.The weak point of this kind sanitary towel is that menses leak and the pollution resistant bed Bed linens from the rear portion of sanitary towel easily when sanitary towel's wearer employing is lain on the back or lain on one's side.

The utility model content

The purpose of this utility model provides a kind of leakproof sanitary towel that prevents the menses front and back leak that has.

The technical scheme that this utility model adopted is such: a kind of leakproof sanitary towel, comprise the liquid permeability surface layer, the opaque liquid bottom and be located at the liquid permeability surface layer and the opaque liquid bottom between absorbent cores, described liquid permeability surface layer, opaque liquid bottom and absorbent cores are each other by the melt viscosity integrator, described liquid permeability surface layer top is provided with application of anti-leakage layers, four outsides of described application of anti-leakage layers are along affixed with the liquid permeability surface layer, the centre of application of anti-leakage layers is provided with perforate so that menses unhinderedly contact with the liquid permeability surface layer, described perforate both lateral sides is respectively equipped with the folding part along near application of anti-leakage layers, extend along the longitudinal direction of sanitary towel respectively described each folding part, and be positioned at the folding part and be provided with the elastic component that extends along the longitudinal component of sanitary towel.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model: by above the liquid permeability surface layer, application of anti-leakage layers being set, the middle part of application of anti-leakage layers is provided with perforate, the folding part of application of anti-leakage layers is provided with elastic component, thereby work as sanitary towel in use, make the curved extension of sanitary towel based on the physiological curve of human body, the folding part of application of anti-leakage layers can upwards erect under the effect of elastic component like this, application of anti-leakage layers partly covers the liquid permeability surface layer of both sides, sanitary towel front and back simultaneously, fundamentally prevents the generation of menses front and back leak phenomenon.

The specific embodiment

With reference to figure 1; Fig. 2 and Fig. 3; embodiment of the present utility model discloses a kind of leakproof sanitary towel; what it comprised stacked setting from top to bottom successively refuses water non-woven fabrics 1; hydrophilic nonwoven fabrics 2; water conservancy diversion layer 3; absorbent paper 4; absorbent cores 5; cast film 6; middle release paper 7 and the flap release paper 8 of pasting; wherein; described absorbent cores 5 is made by the paper oar fiber and the super water-absorbing resins of toilet paper parcel; the top of absorbent cores 5 is located in absorbent paper 4; water conservancy diversion layer 3 is located at the top of absorbent paper 4; hydrophilic nonwoven fabrics 2 is located at the top of water conservancy diversion layer 3; cast film 6 is located at the below of absorbent cores 5; described cast film 6; absorbent cores 5; absorbent paper 4; water conservancy diversion layer 3 and hydrophilic nonwoven fabrics 2 form the sanitary towel with certain imbibition ability by the melt viscosity integrator successively; described hydrophilic nonwoven fabrics 2 forms flap 26 to horizontal two side portions horizontal expansion respectively with the longitudinal middle part of cast film 6; for better fixedly sanitary towel position in use; subsides release paper 7 and flap release paper 8 were used to protect the fixing glue of correspondence position during the bottom surface of described cast film 6 was provided with; it is known technology that aforementioned each ingredient except that refusing water non-woven fabrics 1 and relative fixed are closed; and absorbent paper 4 or water conservancy diversion layer 3 can not established in the top of absorbent cores 5, and it can be used as sanitary towel equally and uses.On this basis, this utility model is provided with one deck at the upper surface of hydrophilic nonwoven fabrics 2 and refuses water non-woven fabrics 1, described four outsides of water non-woven fabrics 1 of refusing are along affixed by PUR with hydrophilic nonwoven fabrics 2, the centre of refusing water non-woven fabrics 1 is provided with perforate 12 so that menses can unhinderedly contact with hydrophilic nonwoven fabrics 2, be positioned at described perforate 12 both lateral sides and be respectively equipped with folding part 13 on the water non-woven fabrics 1 along near refusing, described folding part 13 is to refuse water non-woven fabrics 1 along the protruding up or down coincidence part that is folded to form of horizontal direction, extend along the longitudinal direction of sanitary towel respectively described each folding part 13, and be positioned at folding part 13 and be provided with the elastomeric polyurethane fiber band 11 that extends along the longitudinal component of sanitary towel.

Aforementioned sanitary towel when in use, menses can directly contact with hydrophilic nonwoven fabrics 2 realizes fast Absorption, can prevent effectively that the side leakage of the menses left and right sides, preceding leakage and back from leaking and refuse water non-woven fabrics 1, can prevent the reverse osmosis phenomenon effectively simultaneously, makes dress more comfortable.
