According to the design, the absorption performance is not affected, meanwhile, the sanitary towel has good elasticity and rebound resilience, the stability of the whole structure is enhanced, the towel body is elastic and not prone to deformation, the side leakage prevention capacity is effectively improved, and inconvenience brought by women in the menstrual period is reduced.

Description

Technical Field

[0001] This utility model relates to the field of sanitary napkin technology, specifically a sanitary napkin that is not easily deformed and has good resilience. Background Technology

[0002] As an essential daily necessity for women, the design of sanitary napkins directly impacts the user experience. Traditional sanitary napkins generally have similar structures, prioritizing absorbency while neglecting comfort.

[0003] However, during menstruation, women often move around or exercise due to daily work and life needs, causing the sanitary napkins that were originally stuck to their underwear to become severely deformed, resulting in menstrual blood leaking onto their underwear and clothes, which cannot meet the needs of more users.

[0004] Therefore, in order to correct the above-mentioned defects, we propose a sanitary napkin that is not easily deformed and has good resilience. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a sanitary napkin that is not easily deformed and has good resilience.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sanitary napkin that is not easily deformed and has good resilience, comprising a surface layer, an absorbent layer, a bottom layer, a release paper, a wrapping film, and leak-proof wings on both sides. The surface layer, bottom layer, release paper, wrapping film, and absorbent layer are all bonded and fixed by hot melt adhesive. The absorbent layer comprises an upper absorbent core layer and a support layer from top to bottom.

[0007] Furthermore, the support layer is evenly distributed on the bottom of the upper layer of the absorbent core by being cut short with a cutter.

[0008] Furthermore, the support layer is one of hot-air nonwoven fabric, spunlace nonwoven fabric, or polyester sponge.

[0009] Furthermore, the upper layer of the absorbent core comprises, from top to bottom, fluff pulp and highly absorbent resin.

[0010] Furthermore, the surface layer is made of a skin-friendly fabric.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention uses a supporting material layered at the bottom of the absorbent layer. The porous structure of this material allows the product to quickly regain its original shape after compression of the thighs, even with significant movement during menstruation. This design ensures that absorbency is not compromised while also giving the sanitary napkin good elasticity and resilience, enhancing overall structural stability, making the napkin flexible and less prone to deformation, effectively improving leak-proof capabilities, and reducing inconvenience during menstruation.

[0016] 1. Top layer; 2. Absorbent layer; 3. Bottom layer; 4. Release paper; 5. Wrapping film; 6. Leak-proof wings on both sides; 7. Superabsorbent resin; 8. Fluff pulp; 9. Support layer. Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a technical solution:

[0019] Please see Figure 1-3 A sanitary napkin with good resilience and resistance to deformation is disclosed, comprising a top layer 1, an absorbent layer 2, a bottom layer 3, a release paper 4, a cover film 5, and leak-proof wings 6 on both sides. The top layer 1, bottom layer 3, release paper 4, cover film 5, and absorbent layer 2 are all bonded together with hot melt adhesive. The absorbent layer 2 includes an upper absorbent core and a support layer 9 from top to bottom. The connection structure of the top layer 1, absorbent layer 2, bottom layer 3, release paper 4, cover film 5, and leak-proof wings 6 is not fundamentally different from the prior art, so it will not be described in detail.

[0020] The support layer 9 is one of hot-air nonwoven fabric, spunlace nonwoven fabric, or polyester sponge. The support layer 9 is evenly distributed at the bottom of the upper layer of the absorbent core by short cuts. The upper layer of the absorbent core includes fluff pulp 8 and super absorbent resin 7 from top to bottom. Its internal pore structure allows it to recover its original shape after being squeezed by external force. It can change with the direction of human movement and then return to its original shape. Through the combination of super absorbent resin 7, fluff pulp 8, and support layer 9, and the support layer 9 being evenly distributed at the bottom of the absorbent core layer by short cuts, the sanitary napkin itself will not deform. This allows the sanitary napkin to quickly recover its original shape even if the woman moves a lot during menstruation, while also quickly absorbing menstrual blood and effectively preventing side leakage.

[0021] In addition, the surface layer 1 is made of skin-friendly fabric.

[0022] This invention proposes a sanitary napkin with excellent resilience and resistance to deformation. A supporting material is placed at the bottom of the absorbent layer. The porous structure of this material allows the napkin to quickly regain its original shape after compression in the thighs, even during menstruation, despite significant movement. This design ensures good absorbency while also providing excellent elasticity and resilience, enhancing overall structural stability, making the napkin resilient and less prone to deformation, effectively improving leak prevention and reducing embarrassment during menstruation. Furthermore, this structure is simple, rationally designed, and has low manufacturing costs.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
