The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, provides a kind of, and both sides do not seal the edge, can form the modified model sanltary towel of ship side shape flap after the bending naturally.

The sanltary towel that provides according to this utility model, comprise the sandwich layer that one deck is at least made with absorbing material, its middle part has the part of relative narrower, the antiseepage counterdie that is coated on the non-woven fabrics of described sandwich layer one side external surface and is coated on described sandwich layer opposite side, be overlapped on behind two side edgefolds of described non-woven fabrics on two side external surfaces of described antiseepage counterdie, thereby form the overlap of a no sandwich layer respectively in narrower part both sides, described sandwich layer middle part, the overlap of described two no sandwich layers has been formed separately an arc sealing-in section.

Compared with the prior art, the sanitary towel that this utility model provides has following advantage: (one) is because the both sides of non-woven fabrics are to be overlapped on behind the flanging on two side external surfaces of described antiseepage counterdie, both sides do not seal the edge, thereby can keep the flexibility of both sides non-woven fabrics, during with contact skin, can not produce any uncomfortable sensation; (2) because the overlap joint back forms the overlap of a no sandwich layer respectively in narrower part both sides, sandwich layer middle part, and the overlap of two no sandwich layers has been formed separately an arc sealing-in section, thereby can form softish ship side shape flap naturally after being bent when using, can prevent leakage phenomenon effectively; (3) owing to cancelled the conventional sanitary towel flap overhanging, can save a large amount of non-woven fabrics and antiseepage counterdie from both sides of the edge.

Embodiment below in conjunction with accompanying drawing provides describes this utility model in detail.Wherein:

Fig. 1 is the vertical view according to sanltary towel embodiment of the present utility model;

Fig. 2 is the schematic sectional view along A-A hatching among Fig. 1;

Fig. 3 is the user mode sketch map according to sanltary towel embodiment of the present utility model.

Referring to Fig. 1, shown in it according to the vertical view of sanltary towel embodiment of the present utility model, comprise the sandwich layer 1 that one deck is made with absorbing material, its middle part has the part of the relative narrower of representing with double dot dash line, it is similar also to be superimposed with the shape that another layer make with absorbing material on this sandwich layer 1, but the less sandwich layer 1 ' of size; Be coated on the non-woven fabrics 2 and the antiseepage counterdie 3 that is coated on two superimposed sandwich layer opposite sides of two superimposed sandwich layer one side external surfaces, this antiseepage counterdie 3 can adopt casting films (PE film).

Referring to Fig. 2, this figure is the schematic sectional view along A-A hatching among Fig. 1.Be overlapped on behind two lateral bucklings of above-mentioned non-woven fabrics 2 on two side external surfaces of above-mentioned antiseepage counterdie 3, thereby form two overlaps 4 that cardinal principle is parallel.As shown in Figure 1, back overlap 5 hot formings that form overlap 5, the two no sandwich layers of a no sandwich layer in the narrower part both sides shown in the above-mentioned sandwich layer 1 middle part chain-dotted line respectively of overlap joint have an arcuate break sealing-in section 6.The overlap 5 of above-mentioned non-woven fabrics 2 and described antiseepage counterdie 3 is that the part bonds together in a distance, distance both sides of the edge 7, and this distance can be 1/2 to 2/3 of a lap belt width, forms by applying to bond behind the binding agent.
