Detailed Description

In order to make the technical problems, technical solutions adopted and technical effects achieved by the present invention clearer, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings, and obviously, the described embodiments are only some embodiments, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by the skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Wherein the terms "first position" and "second position" are two different positions.

The utility model provides a take protruding sanitary towel, this sanitary towel is for taking flap sanitary towel, from last to being equipped with surface course 1, absorption sandwich layer 3 and basement membrane layer 4 (as shown in figure 1) down, surface course 1 is direct and the skin contact, preferably hot-blast non-woven fabrics, and 4 preferred polyethylene films in the basement membrane layer of prevention of seepage, waterproof material can remain excrement such as menstrual blood in absorption sandwich layer 3. Can set up water conservancy diversion layer 2 between surface course 1 and the absorption sandwich layer 3, water conservancy diversion layer 2 drains absorption sandwich layer 3 fast with the secretion in the surface course 1, guarantees surface course 1 dry and comfortable, improves and uses the travelling comfort. The absorbent core layer 3 may be a wood pulp layer or a composite core. The wood pulp layer is formed by crushing wood pulp into fluff pulp on a production line; the composite core body is a prefabricated water-absorbing lining paper, can be made into three layers or five layers, is made by adopting a gluing or heat sealing mode, and can also be directly stacked and adhered with the surface layer 1 and the bottom film layer 4.

The utility model discloses in, absorb sandwich layer 3 is the integrated configuration of wood pulp layer, compound core or slip sheet that absorbs water, and the wood pulp layer is for absorbing the main part, sets up in the middle part position, and compound core or the slip sheet that absorbs water wraps up the wood pulp layer, for guaranteeing the absorption effect, adopts U-shaped parcel mode, and upper portion is the open-type promptly, and side and bottom surface then are equipped with compound core or the slip sheet that absorbs water. Specifically, there are two groups of embodiments as follows.

Example 1:

the absorbent core layer 3 is composed of a wood pulp layer 31 and a composite absorbent core layer 35, the composite absorbent core layer 35 wraps the side and the bottom of the wood pulp layer 31, and the upper part of the wood pulp layer 31 is exposed (i.e. the protrusion 34) and is higher than the upper end surface of the composite absorbent core layer 35 (as shown in fig. 2). A small amount of high molecular water-absorbing resin 33 can be added into the composite absorption core layer 35, and the high molecular water-absorbing resin 33 can be added into the middle and two sides of the core body according to different proportions so as to improve the absorption performance. The composite absorption core layer 35 can be realized by wrapping dust-free paper, which is also called dry-process papermaking non-woven fabric, with absorbent paper, and has high elasticity, softness, excellent hand feeling and excellent drapability. In this embodiment, the dust-free paper 32 is disposed between the composite absorbent core layer 35 and the wood pulp layer 31, and meanwhile, fluff pulp can be laid on the dust-free paper 32.

Example 2:

the absorption core layer 3 is composed of a wood pulp layer 31 and water absorption lining paper 36, the wood pulp layer 31 is in a boss shape, the water absorption lining paper 36 wraps the wood pulp layer 31, the protrusions 34 of the wood pulp layer 31 are exposed above the water absorption lining paper 36, and the water absorption lining paper 36 wraps the convex shoulder and the whole bottom (as shown in fig. 3). The wood pulp layer 31 can be added with the high polymer water-absorbing resin 33, the high polymer water-absorbing resin 33 in the middle of the absorbing core layer 3 has low proportion and low density, the high polymer water-absorbing resin 33 around the absorbing core layer has high proportion and high density, thus the absorbing speed of the middle part is high, and a large amount of high polymer water-absorbing resin distributed around the absorbing core layer can play a role of retaining wall and can prevent liquid from leaking.

The planar shape of the protrusion 34 of the wood pulp layer 31 in the embodiments 1 and 2 is as shown in fig. 4, the protrusion 34 includes a front end 341, a middle part 342 and a rear end 343 which are connected in sequence, the front end 341 and the rear end 343 are wider, the end is of a fan-shaped structure, the middle part 342 is of an oval structure, the protrusion height of the middle part 342 is the highest, the height of the protrusion extending to the

positions

341 and 343 is gradually reduced to form different density gradients, so that the sanitary napkin completely fits the body of a woman.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still belong to the protection scope of the present invention.
