Technical Field
The utility model relates to a leak protection type sanitary towel structure.
Background
A sanitary napkin, also known as a sanitary towel, is an absorbent material mainly made of cotton-like pulp and a polymeric absorbent for absorbing menstrual blood from the vagina when women have menstrual flow.
The sanitary napkin can be divided into a surface layer, an absorption core and a bottom layer.
The materials of each layer are bonded by hot melt adhesive.
The surface layer is the part directly contacting with the skin, the material is soft, and the surface weave and the indentation can influence the reverse osmosis effect (dryness and comfort) of the sanitary towel.
The PE perforated film surface layer and the cotton surface layer are two most commonly used materials, and due to the microporous design of the PE surface layer, menstrual blood is not easy to permeate back, and a user can feel dry, but the materials are hard, and part of the user can cause anaphylactic reaction; due to the improvement of cotton absorption capacity design and the appearance of punching type and composite type materials, the market share after 2001 is gradually higher than that of the sanitary cotton with the PE surface layer.
The inner layer is mainly made of cotton, non-woven fabric, paper pulp or high molecular polymer and high molecular polymer composite paper formed by the above materials, and is used for absorbing the flowing menstrual blood. The design of side mainly is used for preventing the edge leakage, because can present certain angle with the sanitary-napkin body during the use, more easily with the part of the groin come to the friction, consequently use the sanitary-napkin of the side of soft material to favor by women. The back glue of the sanitary napkin is a waterproof material, can retain menstrual blood in the sanitary napkin, develops the self-adhesive back glue in the 70-80 years, and is convenient for fixing the sanitary napkin on the underpants.
However, in the sanitary napkin of the prior art, there is a gap between the sanitary napkin and the vaginal opening, and menstrual blood flows out from the gap and then accumulates toward one location, resulting in uneven absorption and easy occurrence of one-way leakage detection.
Therefore, the leakage-proof sanitary towel structure which can be attached to the pudendum and enables the permeation to be more uniform is designed.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a leakage-proof sanitary towel structure which can be attached to the private part and can enable the penetration to be more uniform is provided.
The utility model discloses a realize through following technical scheme:
a leakage-proof sanitary towel structure comprises a surface layer, an anti-reverse osmosis layer, a central absorption layer, an anti-osmosis layer, a bottom layer, gum and release paper, wherein the surface layer, the anti-reverse osmosis layer, the central absorption layer, the anti-osmosis layer, the bottom layer, the gum and the release paper are sequentially arranged from top to bottom; the surface of the surface layer is provided with a first absorption area and a second absorption area which are protruded, the first absorption area is positioned on the inner side of the second absorption area, and a diversion trench is formed between the first absorption area and the second absorption area; an oval-shaped protrusion is provided at a middle position of the first absorption region.
Preferably, a first diversion trench is arranged at the periphery of the bulge at the top of the first absorption area; the design purpose of guiding gutter is when the ability that the bellying absorbed menstrual blood is not enough, lets the menstrual blood get into first guiding gutter and shunts.
Preferably, the transverse length of the convex part is 5 cm-10 cm.
Preferably, wing portions are provided at both front and rear side positions of the skin layer.
Preferably, the height of the first absorption area is lower than that of the second absorption area, and the height difference is 0.1-0.2 mm; the effect of the structure is that the air permeability of the pudendum is increased, the second absorption area at the outer side plays a role in seepage prevention, the first absorption area at the inner side performs transitional absorption, but a small gap is reserved between the pudendum and the first absorption area for air permeability.
The utility model has the advantages that: in this product, the bellying of design can block in vaginal orifice position department, and the back is flowed out in the vagina to the menstrual blood, and direct contact bellying absorbs the menstrual blood through the bellying, then shunts, avoids the menstrual blood side leakage, and the simple structure of this product, low cost is fit for using widely.
