Description

Technical Field

[0001] This utility model relates to the field of hygiene products technology, and in particular to a fast-absorbing three-dimensional suspended sanitary napkin. Background Technology

[0002] Sanitary napkins are a common disposable hygiene product used by women during menstruation. They are usually made of a composite material consisting of a top layer, a core, and a bottom film. Currently, existing sanitary napkins still have the following problems: 1. Although sanitary napkins generally have leak-proof sides, users are not always in a stationary state. When there is a certain degree of movement, side leakage may still occur; 2. The absorption speed of sanitary napkins is insufficient, resulting in slow absorption. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fast-absorbing three-dimensional suspended sanitary napkin to solve the problems of side leakage and slow absorption.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A fast-absorbing, three-dimensional suspended sanitary napkin comprises, from bottom to top, a bottom film, a lower core, an upper core, and a top layer. The bottom film includes an adhesive portion and a wing portion. The lower core is fixed to the adhesive portion. The wing portion is located around the adhesive portion and has adhesive on its back for attaching to the user's underwear. Arched elastic sheets parallel to the length of the sanitary napkin are fixed to both sides of the top surface of the lower core. The upper core is fixed to the lower core only at both ends. Elastic cords are fixed to the sides of the upper core, and the other end of the elastic cords is fixed to the wing portion. The top layer is fixed to the upper core.

[0006] Furthermore, it also includes two edgings, respectively located on both sides of the surface layer. One side of the edging is fixed to the surface layer, and the other side is fixed to the wing portion. The middle part of the edging is not fixed.

[0007] Furthermore, the bottom film has two layers for adhesive fixation on the wing portion, and the other end of the elastic rope is fixed between the two layers of the bottom film.

[0008] Furthermore, the wing portion is formed by folding and pasting the base film.

[0009] Furthermore, each side of the top surface of the lower core is provided with three parallel arched elastic plates, and the three arched elastic plates are arranged at equal intervals.

[0010] Furthermore, the elastic rope is located on the outside of the arched elastic sheet.

[0011] Furthermore, the upper core is provided with a number of upper air vents.

[0012] Furthermore, the lower core is provided with a number of lower vent holes.

[0013] Furthermore, the arched elastic sheet is disposed in the middle of the sanitary napkin along its length.

[0014] The beneficial effects of this utility model are:

[0015] This invention enhances the anti-leakage effect of sanitary napkins by setting an arched elastic sheet; at the same time, the arched elastic sheet and elastic cord create a suspension cavity between the upper and lower core layers, increasing the absorbency of the sanitary napkin. This invention has good anti-leakage and absorbency effects. Attached Figure Description

[0022] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1-5As shown, this utility model provides a fast-absorbing three-dimensional suspended sanitary napkin, which includes a bottom film 1, a lower core 2, an upper core 3, and a surface layer 4 from bottom to top. The bottom film 1 includes an adhesive part 11 and a wing part 12. The lower core 2 is fixed on the adhesive part 11. The wing part 12 is located around the adhesive part 11 and has adhesive on its back for sticking to the user's underwear. The back of the adhesive part 11 also has adhesive for sticking to the user's underwear. Arched elastic sheets 5 parallel to the length direction of the sanitary napkin are fixed on both sides of the top surface of the lower core 2. The upper core 3 is fixed to the lower core 2 at only two ends. Several elastic ropes 6 are fixed on the side of the upper core 3. The other end of the elastic ropes 6 is fixed to the wing part 12. The surface layer 4 is fixed on the upper core 3.

[0024] When the wing part 12 is attached to the underwear in the opposite direction, the elastic cord 6 will be pulled. At this time, the elastic cord 6 is in a stretched state, and the elastic cords 6 on both sides will unfold the upper core 3 in the width direction. Since the elastic cord 6 is pulled downward, the bottom surface of the upper core 3 will press against the arched elastic sheet 5. In this way, the arched elastic sheet 5 is supported between the lower core 2 and the upper core 3. The arched elastic sheet 5 has a certain height and length, and the position of the arched elastic sheet 5 can form a leak-proof structure. Moreover, at this time, a suspension cavity is formed between the lower core 2 and the upper core 3, and the upper core 3 is similar to a suspended state. Under this structure, the sanitary napkin can quickly absorb menstrual blood.

[0025] The upper core 3 is fixed at both ends, which restricts its position and prevents it from shifting. Of course, to further restrict the position of the upper core 3, it can be fixed to the lower core 2 along its width, using a smaller fixing area.

[0026] The 3D suspended sanitary napkin also includes two side bindings 7, located on both sides of the surface layer 4. One side of the side binding 7 is fixed to the surface layer 4, and the other side is fixed to the wing portion 12. The middle part of the side binding 7 is not fixed. The side bindings 7 are mainly used to cover the elastic cord 6 and the side edges of the surface layer 4, further defining the position of the upper core 3, and also preventing the elastic cord 6 from contacting the skin.

[0027] Furthermore, the base film 1 has two layers for adhesive fixation on the wing portion 12, and the other end of the elastic rope 6 is fixed between the two layers of the base film 1. The wing portion 12 is formed by folding and adhesiveting the base film 1 in half.

[0028] Furthermore, each side of the top surface of the lower core 2 is provided with three parallel arched elastic sheets 5, which are equidistantly spaced. As a preferred embodiment, the arched elastic sheets 5 are located near the edge of the lower core 2 to prevent side leakage.

[0029] Furthermore, the elastic rope 6 is located on the outside of the arched elastic sheet 5.

[0030] Furthermore, the upper core 3 has several upper air vents 8, and the lower core 2 has several lower air vents 9. The upper air vents 8 and lower air vents 9 enhance the breathability and absorbency of the sanitary napkin.

[0031] Furthermore, the arched elastic sheet 5 is positioned in the middle of the sanitary napkin along its length. Sanitary napkins are typically folded into three sections and wrapped in packaging paper during manufacturing, and the area where the sanitary napkin absorbs the most liquid is in the middle; therefore, it is sufficient to position the arched elastic sheet 5 in the middle along its length.

[0032] This invention enhances the anti-leakage effect of sanitary napkins by setting an arched elastic sheet 5; at the same time, the arched elastic sheet 5 and elastic rope 6 form a suspension cavity between the upper core 3 and the lower core 2, increasing the liquid absorption speed of the sanitary napkin. This invention has good anti-leakage and liquid absorption effects.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
