Description

Leak-proof sanitary towel

Technical Field

The utility model relates to a disposable absorption article, in particular to a leak-proof sanitary towel.

Background

Menses is a female's lower body bleeding at the beginning and end of the menstrual cycle, the most obvious sign of girls becoming women. When the girls are happy and mature, the trouble brought by each menstrual period is accompanied, the female generally enters the menopause in the age of 12-16 years, and the trouble can last for decades along with the menopause in the age of 52-55 years.

When the traditional Chinese medicine is used by women in large amount, a large amount of menstrual blood cannot be absorbed immediately, and the menstrual blood flows to two sides and easily leaks laterally; when the ordinary sanitary towel is used at night, menstrual blood easily flows out from the gap position of the buttocks to a position above the buttocks, and back leakage is caused.

The existing sanitary towel structure sequentially comprises the following components from top to bottom: the wood pulp core-type absorbent material comprises a surface layer, an absorbent layer and a bottom layer, wherein the absorbent layer is generally a wood pulp core structure or a composite core structure. The improvement method aiming at the side leakage and the rear leakage respectively comprises the steps of increasing a three-dimensional enclosure structure, increasing the length of a product and widening the width of an empennage. When the product is actually used, the product is in a flattened state after being worn, and the three-dimensional guard can not ensure the three-dimensional state, so that when a woman is in a large amount, a large amount of menstrual blood flows out, and the guard can not play an effective protection role, so that side leakage occurs. The problem of back leakage can be solved by increasing the length of the product to extend to the position above the buttocks, but the buttocks are stuffy and hot due to the long-time lying state at night, so that the probability of skin problems is increased.

In the description of the present invention, unless there is an explicit limitation, the words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in combination with the specific contents of the technical solution.

Referring to fig. 1 to 3, an embodiment of the present invention provides a leakproof sanitary napkin, which mainly comprises a surface layer 10, a core layer 30 and a bottom layer 20 stacked in sequence from top to bottom. The layers are bonded by hot melt adhesive. The hot melt adhesive is spirally sprayed to reduce the adhesive consumption and reduce the cost.

Specifically, the core layer 30 includes a wood pulp core including three wood pulp absorbent strips 302 arranged in a strip shape, and a composite core 303, the three wood pulp absorbent strips 302 being respectively disposed above the composite core 303, and the three wood pulp absorbent strips 302 being respectively located at both side portions and a trailing end portion of the composite core 303, the three wood pulp forming three "protective walls". The superposition of two kinds of cores is used, lets the product form dual "protecting wall", utilizes the wood pulp core to absorb fast, compound core 303 absorbed volume big advantage, and in the big period of volume, the menstrual blood that disperses to both sides can firmly be absorbed by both sides "protecting wall", avoids the side leakage. For the use at night, the lower protective wall is tightly attached to the femoral sulcus, and the menstrual blood flowing downwards can be absorbed instantly to avoid back leakage.

In processing the core layer 30, the core forming die is adjusted to correspondingly provide three grooves for processing three absorbent wood pulp strips 302.

In this embodiment, the absorbent wood pulp strips 302 are made from a mixture of wood pulp and SAP particles. The composite core 303 includes a first dust-free paper layer, an SAP particle layer, and a second dust-free paper layer stacked in sequence from top to bottom. The absorbent and leak-proof capabilities of the overall core layer 30 are ensured by the composite superposition of the wood pulp absorbent strips 302 with the composite core 303.

Preferably, as the outermost wrapping layer 301 of the core layer 30, a hydrophilic SMS nonwoven fabric is used as the wrapping layer 301 in this embodiment, and the wood pulp core and the composite core 303 are wrapped with the hydrophilic SMS nonwoven fabric. The hydrophilic SMS non-woven fabric comprises a first spunbond layer, a melt-blown layer and a second spunbond layer which are compositely connected into a whole from top to bottom. The hydrophilic SMS non-woven fabric is formed by compounding two spun-bonded layers and a melt-blown layer sandwiched between the two spun-bonded layers, has great advantages in fracture strength, and avoids the phenomenon of SAP (super absorbent polymer) granule seepage caused by movable extrusion.

Further preferably, a disposal tape 202 is further provided on the back of the bottom sheet 20 of the sanitary napkin, and after the disposal tape 202 is folded in half several times, one end thereof is adhered to the rear end portion of the back of the bottom sheet 20. The length of the disposal label 202 is adjusted according to different sizes of the sanitary napkin, and the disposal label 202 can be effectively fixed by winding the disposal label 202 after the absorbed product is rolled up because the folding times of the disposal label 202 are more than 2 times. By adding the design, more women can be guided to educate and place the products used in menstrual periods after finishing instead of being discarded at will, convenience is brought to cleaning personnel, and public sanitation can be maintained.

Meanwhile, the back of the bottom layer 20 is further provided with a plurality of strip-shaped back adhesives 201, and in the embodiment, the three strip-shaped back adhesives 201 are arranged on the back of the bottom layer 20 at equal intervals, so that underwear can be conveniently pasted.

The back of the bottom layer 20 is provided with a PE embossed film. The PE embossed film consists of PE and CaCO3, a certain number of micropores are generated after tape casting, unidirectional or bidirectional stretching, and a plurality of concave holes are distributed on the PE embossed film, so that the sanitary towel has waterproofness and moisture permeability.

The surface layer 10 is a hydrophilic non-woven fabric, so that the surface layer 10 has good hydrophilicity, is fine and soft, can reduce the friction force with the skin, and enables a user to feel comfortable.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art.
