Description

Technical Field

[0001] This utility model relates to the field of sanitary napkin technology, specifically a stretchable sanitary napkin. Background Technology

[0002] Sanitary napkins are an essential item for women during menstruation. They are placed inside underwear to absorb menstrual blood. Sanitary napkins have adhesive on the bottom film, and when used, they are attached to the crotch area of ​​the underwear using the adhesive strips on the sides. Because of the adhesive, these sanitary napkins are less likely to shift or fall off, making them convenient and safe to use. However, the length of existing sanitary napkins is fixed, while the length and width of the crotch area of ​​underwear are not uniform. This can lead to situations where the sanitary napkin and its adhesive strips cannot cover the area properly. When sitting, the pressure of the posture can cause menstrual blood to rise, and when lying down, the blood flows smoothly, resulting in soiling of the areas near the abdomen and tailbone, causing inconvenience for women.

[0003] The length and width of the crotch area of ​​existing underwear are not uniform, which leads to leakage problems due to inadequate coverage by sanitary napkins and sanitary napkin adhesive pads.

[0004] Therefore, it is particularly important to design a stretchable sanitary napkin to overcome the above-mentioned technical defects and improve its overall practicality. Utility Model Content

[0008] As a preferred embodiment of this utility model, the protective sheet, the first extension sheet, and the adhesive sheet are provided with self-adhesive on one side, and the second extension sheet is provided with self-adhesive on both sides, with release paper on the self-adhesive.

[0009] As a preferred embodiment of this utility model, the first adhesive disc, the second adhesive disc, and the third adhesive disc are made of acrylic adhesive.

[0010] As a preferred embodiment of this utility model, the first extension piece is fan-shaped and has creases, and the two sides of the first extension piece can be folded along the creases.

[0011] As a preferred embodiment of this utility model, the cotton block is adapted to the groove, and the cotton block is fixedly connected to the first extension piece.

[0012] As a preferred embodiment of this utility model, one end of the second extension piece is symmetrically provided with a slot, the slot is semi-arc-shaped and adapted to the third adhesive disc, and a crease is provided between the adhesive disc and the second extension piece, so that the second extension piece can overlap the adhesive disc along the crease.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a retractable sanitary napkin is designed using a structure of a protective sheet, an adhesive disc, a groove, a cotton pad, and an extension piece. The adhesive disc creates a gap between the bottom film and the protective sheet, which accommodates a first extension piece and a second extension piece. The second extension piece and the adhesive piece work together to accommodate different underwear widths, preventing the adhesive piece from being insufficient. The position of the first extension piece can be adjusted by the groove and the cotton pad, and its orientation can be adjusted according to different sitting or lying positions. This solves the problem of inconsistent length and width of the crotch area of ​​existing underwear, which leads to leakage due to insufficient coverage by the sanitary napkin and its adhesive piece.
