The principles and spirit of the present utility model are explained in detail below with reference to several representative embodiments thereof.
Example 1 of a sanitary product liquid absorbing structure provided by the present utility model:
As shown in fig. 1 and 2, the absorbent body 1 comprises an absorbent body 1 extending along the front-rear direction, a surface layer 4 arranged on the upper surface of the absorbent body 1 and contacted with skin, and a back layer 5 arranged on the lower surface of the absorbent body 1, in this embodiment, the absorbent body 1 comprises a cotton core 6 and a high molecular water absorbent resin 7 (SAP), the surface layer 4 and the back layer 5 are non-woven fabrics, the materials of the absorbent body 1, the surface layer 4 and the back layer 5 can be adjusted and replaced according to the situation, and other surface layers can be added according to the actual situation, for example, a conductive layer 11 can be added into the absorbent body 1 to enable urine to quickly permeate towards the front side and the rear side of the absorbent body 1.
The absorber 1 is provided with an inner embossing line and an outer embossing line for connecting the absorber 1, the surface layer 4 and the back layer 5, wherein the outer embossing line is L1 in the figure, the inner embossing line is L2 in the figure, the inner embossing line and the outer embossing line are concentrically arranged and are all annular, the inner embossing line and the outer embossing line compress the absorber 1 in the thickness direction, the surface layer 4 is forced to squeeze the absorber 1, a raised barrier ring 2 is formed between the inner embossing line and the outer embossing line, a containing cavity 3 for storing liquid and reducing liquid leakage is formed on the inner side of the barrier ring 2, and the cross section of the barrier ring 2 is concave as shown in fig. 2.
The convex separation ring 2 enables the contact part of the product and the female private part to be concave, the concave part can ensure that the product is not in close contact with the private part, uncomfortable feeling caused by friction between the product and the private part when a user walks can be effectively reduced, the inner side of the separation ring 2 is provided with the containing cavity 3, the containing cavity 3 can contain urine, the urine is prevented from diffusing to the periphery, the urine in the containing cavity 3 permeates to the bottom, and the urine is rapidly led to the surrounding absorber 1 by the blue cotton 10.
The shape of the baffle ring 2 is determined by the inner embossing line profile and the outer embossing line profile, and the baffle ring 2 can be olive-shaped or heart-shaped or other shapes which are fit with female private parts.
The surface layer 4 above the barrier ring 2 presses the barrier ring 2, so that the density of the top of the barrier ring 2 (i.e. the area above the broken line L3 in the figure) is higher than that of the bottom of the barrier ring 2, to delay the penetration of liquid to the top of the barrier ring 2, thereby ensuring the long-term drying of the top of the barrier ring 2 and giving the user a dry feel.
The blue cotton 10 is located above the absorber 1, the blue cotton 10 is used for guiding urine to the surrounding, specifically, the blue cotton 10 is arranged inside the baffle ring 2 and extends outwards to between the inner embossing line and the outer embossing line, and the shape of the blue cotton 10 is the same as the outline of the inner embossing line or the outline of the outer embossing line.
The inner side of the barrier ring 2 is further provided with embossing strips for compressing the absorber 1 in the thickness direction, namely L4 in fig. 2, and the embossing strips may be continuous line structures or dot structures arranged at intervals. The embossing strip can reduce the thickness of the absorber 1 on the inner side of the barrier ring 2, and reduce the contact between the female private part and the product. Meanwhile, small annular protrusions are formed between the inner embossed lines and the embossed strips, so that the contact area of the surface layers such as urine and blue cotton is increased, downward diversion of the urine is accelerated, and when the urine amount is small, the small annular protrusions can also play the roles of blocking the urine and reducing the urine flow.
The urine flows onto the product, and bacteria are extremely easy to breed due to the warm and humid environment, so that peculiar smell is generated, and the urine also has peculiar smell sources such as ammonia gas and the like. The absorber 1 is internally added with the macromolecular water-absorbing resin 7 capable of inhibiting bacteria and removing smell (functional auxiliary agents can be added in the conducting layer to achieve the same function), the blocking ring 2 reduces the contact between female private parts and the product, is more beneficial to air circulation, can inhibit bacteria from breeding to reduce the generation of peculiar smell by matching the two components, protects the health of the female private parts, and can reduce the generation of peculiar smell by adsorption and reaction with ammonia molecules. The mild urinary incontinence causes the mild incontinence group to lack of confidence, influences the normal life and social contact of the mild incontinence group, even causes stress on the mind, and can meet the social contact requirement and respect requirement of the group according to the Marlo demand level theory.
