Abstract
Description
Technical Field
[0001] The present application relates to a sanitary napkin, and more particularly to a sanitary napkin that fits snugly and feels smooth. Background Art
[0002] Sanitary towel is a kind of sanitary product used by women during menstruation. The main materials are cotton, non-woven fabric, pulp or polymers and polymer composite paper formed by the above materials. The side design is mainly used to prevent side leakage. From the inside to the outside, it is divided into three layers: surface layer, absorbent core and bottom layer. When using, tear off the paper tape in the middle, stick the adhesive side to the middle of the underwear, and stick the two "ears" to the narrowest part of the crotch. Other common menstrual products include tampons, menstrual cups, panty liners, etc.
[0003] Currently, the common sanitary napkins on the market are divided into sanitary napkins with wings and sanitary napkins without wings, depending on whether they have wings or not. Sanitary napkins without wings are generally mini or pad-type, which are used in very small amounts, and generally do not cause leakage in this case. All sanitary napkins on the market for medium and large amounts have wings. The function of the wings is to stick the sanitary napkin to the underwear without shifting, ensuring that there is no leakage when wearing. However, in the actual wearing process, the non-woven fabrics on both sides of the wings constantly rub against the inner thighs, causing the inner thighs to feel foreign and uncomfortable.
[0004] There are also some sanitary napkin products, such as menstrual pants, which are made of materials that can absorb liquids. The surface that contacts the skin is made of pure cotton. There is indeed a sense of numbness when wearing them, but this kind of menstrual pants is expensive. Generally, they need to be manually washed and dried before reuse after use. They are non-disposable sanitary napkin products.
[0005] To this end, the present application provides a sanitary napkin that fits snugly and feels smooth. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, the present application describes a body-fitting, non-sense sanitary napkin that removes the wing structure and adds a fixing area to overcome the wearing discomfort caused by the friction of the wings, while also overcoming the risk of leakage caused by the sanitary napkin shifting due to loose fixation during use.
[0007] The technical solution adopted by this application to solve its technical problem is:
[0008] A body-fitting, non-sense sanitary napkin comprises a hydrophilic surface layer, an absorbent core layer, a waterproof layer, and leak-proof edges arranged on both sides of the hydrophilic surface layer in sequence from top to bottom, wherein a fixing area that can be fixed on underwear is arranged at the junction of the hydrophilic surface layer and the leak-proof edges.
[0009] By adopting the above-mentioned technical solution, the wings are removed and the sanitary napkin is fixed in the fixed area, which solves the problem that sanitary napkins with wings rub against the legs when worn, resulting in low wearing comfort, while sanitary napkins without wings are likely to shift during use and cause the risk of leakage.
[0010] Preferably, the fixing area is fixed by bonding.
[0011] By adopting the above technical solution, the body-fitting non-sense sanitary napkin is fixed on the underwear by bonding.
[0012] Preferably, the material used for the fixing area is silicone gel lamination or PU lamination.
[0013] By adopting the above technical solution, the body-fitting non-sense sanitary napkin is bonded and fixed by silicone gel lamination or PU lamination, and the fixing effect is better.
[0014] Preferably, the number of the fixed areas is ≥1.
[0015] Preferably, the fixed areas are arranged continuously or discontinuously.
[0016] Preferably, the horizontal distance of the fixing area is X, and the vertical distance is Y; wherein X≤45mm, Y≤10mm.
[0017] By adopting the above technical solution, the fixing areas are arranged in multiple places and of a certain size, so that the sanitary napkin can be firmly fixed and is not easy to fall off.
[0018] Preferably, a guide layer may be provided between the hydrophilic surface layer and the absorbent core layer.
[0019] Preferably, the upper surface of the hydrophilic surface layer is made of 100% pure cotton.
[0020] Preferably, the waterproof layer is made of a breathable PE film or non-woven fabric.
[0021] Preferably, the lower surface of the waterproof layer is compounded with release paper.
[0022] The beneficial effects of this application are:
[0023] 1. Compared with conventional sanitary napkins, the body-fitting non-sense sanitary napkin described in this application has no wings, which greatly improves the wearing comfort;
[0024] 2. Compared with conventional sanitary napkins, the body-fitting, non-sense sanitary napkin described in this application has a significant change in the way the napkin is fixed, from adhesive bonding to silicone gel bonding, and the four corners and both ends of the napkin are fixed, which has a better fixing effect, the napkin is not easy to fold and does not affect the wearing comfort.
