Abstract
Description
Technical area
[0001] The utility model relates to the technical field of women's products, in particular to a double-layered female menstrual underwear. Background technology
[0002] As a daily intimate garment, underwear can protect the genitals and provide comfort, as well as prevent infections or the spread of disease. Choosing the right underwear can help maintain physical and mental health. Different styles of underwear can meet the needs of different people.
[0003] To secure the sanitary napkin to the inner crotch, the back of the existing sanitary napkin is glued to the crotch of the underwear, and the two wings of the sanitary napkin are folded over and glued to the back of the crotch, which corresponds to the underwear. Because sanitary napkins are made of chemical fiber materials, the contact area between sanitary napkins and human skin is large. Long-term contact with them can easily cause symptoms such as allergies on women's skin, which can lead to discomfort. Content of the utility model
[0004] Against this background, the utility model proposes a double-layered underwear for women during menstruation to solve the technical problems. The specific technical solution is as follows: A double-layered feminine menstrual underwear featuring a panty body. The panty body consists of two layers, consisting of an inner layer and an outer layer from the inside out. The inner layer is positioned at the crotch, with both ends open. The inside of the opening protrudes into the space enclosed by the inner layer and the outer layer, and the two ends of the spacer are conveniently embedded in the inside of the opening.
[0005] In addition, the crotch position corresponding to the underwear body is a single layer.
[0006] In addition, the inner layer and the outer layer are pure cotton materials and the thickness of the inner layer is less than the thickness of the outer layer.
[0007] In addition, the spacer is at least one of the sanitary napkins, toilet paper or knife paper.
[0008] Adopting the above-mentioned technical solution has the following positive effects: The utility model places the spacer in the crotch area, and then the two ends of the gasket are embedded into the inside of the opening, thereby reducing the contact area between the gasket and the human skin and reducing symptoms such as skin allergies of the user. In addition, embedding both ends of the spacer in the opening has the effect of limiting the position of the spacer, preventing the spacer from falling off and misaligning the crotch, thereby reducing the possibility of lateral leakage. The crotch part of the utility model can be provided with toilet paper, knife paper, etc., without an adhesive surface, enabling the use of underwear for people with urine leakage, postpartum leakage, etc. Description with drawings Fig. is a schematic three-dimensional structural diagram of a double-layer female menstrual underwear of the utility model.
