Technical Field
[0001] The utility model relates to the technical field of sanitary products, in particular to a floating side guard leak-proof sanitary napkin. Background Art
[0002] A sanitary napkin is a sanitary product used by women during menstruation. At present, the types and styles of sanitary napkins are becoming more and more diverse. However, for the situation of a large amount of menstrual blood during menstruation, most sanitary napkins will have the problem of side leakage due to slow absorption speed, which often brings great troubles to women during menstruation and even affects normal work and life.
[0003] Based on the above situation, how to quickly and dispersedly absorb menstrual blood and how to prevent menstrual blood from leaking sideways are problems that need to be solved urgently. Summary of the Utility Model
[0004] Other features and advantages of the present utility model will be described in the following specification, and will be partially obvious from the specification, or understood by implementing the present utility model. The objectives and other advantages of the present utility model can be realized and obtained through the structures specifically pointed out in the specification and other specification drawings.
[0005] The purpose of the present utility model is to overcome the above deficiencies and provide a floating side guard leak-proof sanitary napkin. The present utility model is provided with floating side guards that are recessed inward on both sides of the surface layer. The upper side guards of the floating side guards are connected to the surface layer, and the lower side guards of the floating side guards are connected to the bottom layer. An opening is provided between the upper side guard and the lower side guard, so that the upper side guard is suspended, which can effectively prevent the occurrence of side leakage of menstrual blood.
[0006] The present utility model provides a floating side guard leak-proof sanitary napkin, which includes a surface layer and a bottom layer. The surface layer is arranged above the bottom layer. Floating side guards are recessed inward on both sides of the surface layer. The floating side guards include an opening, an upper side guard and a lower side guard. The upper side guard is connected to the surface layer, and the lower side guard is connected to the bottom layer. The opening is provided between the upper side guard and the lower side guard. The present utility model is provided with floating side guards that are recessed inward on both sides of the surface layer. The upper side guards of the floating side guards are connected to the surface layer, and the lower side guards of the floating side guards are connected to the bottom layer. An opening is provided between the upper side guard and the lower side guard, so that the upper side guard is suspended, which can effectively prevent the occurrence of side leakage of menstrual blood.
[0007] In some embodiments, both the upper side guard and the lower side guard are in the shape of an isosceles trapezoid. The isosceles trapezoid is narrower at the top and wider at the bottom. The upper side guard and the lower side guard are symmetrically arranged in the shape of an isosceles trapezoid, so that the opening is in a U shape, increasing the opening space and further increasing the sense of suspension of the upper side guard.
[0008] In some embodiments, the length of the floating girdle is less than the length of the surface layer. The occurrence of side leakage mainly concentrates on the middle section of the sanitary napkin. Therefore, the length of the floating girdle can be less than the length of the surface layer.
[0009] In some embodiments, the surface layer, from top to bottom, is successively a skin-friendly layer, an antibacterial sheet, a water-absorbing layer, and a dust-free paper absorption layer. The bottom layer is a breathable film layer. The skin-friendly layer, the antibacterial sheet, the water-absorbing layer, the dust-free paper absorption layer, and the breathable film layer are connected by hot melt adhesive. The hot melt adhesive has strong viscosity and good stability. The connection by hot melt adhesive has strong stability, and the layers will not shift. The skin-friendly layer is preferably a pure cotton surface layer or a soft cotton surface layer. The antibacterial sheet plays an antibacterial and bacteriostatic role. The water-absorbing layer is preferably a superabsorbent resin, and the dust-free paper absorption layer is preferably fluff pulp to enhance the absorption capacity. The bottom layer is a breathable film layer.
[0010] In some embodiments, the width of the bottom layer is greater than the width of the surface layer, the width of the rear end of the bottom layer is greater than the width of the front end of the bottom layer, and the rear end of the bottom layer is designed with an arc-shaped lace. The large arc-shaped lace design at the rear end of the bottom layer can play a more effective wrapping role to prevent side leakage.
[0011] In some embodiments, the surface layer is provided with a plurality of diversion grooves. The diversion grooves can promote the rapid and dispersed absorption of menstrual blood and reduce the contact time between menstrual blood and the skin.
[0012] In some embodiments, the surface layer is respectively provided with a flower-shaped diversion groove, an arc-shaped diversion groove, an open annular diversion groove, and a heart-shaped diversion groove. Different diversion grooves distributed on the surface layer can play a multiple drainage and diversion function, improve the diffusion length, and increase the transmission speed.
[0013] In some embodiments, winglets are extended and provided on both sides of the bottom layer. The winglets are symmetrically arranged, and there is 1 pair or 2 pairs of winglets. The setting of the winglets can make the use of the sanitary napkin convenient and fast.
[0014] In some embodiments, the thickness of the upper girdle is the same as the thickness of the surface layer, and the thickness of the lower girdle is greater than the thickness of the bottom layer. The same thickness of the upper girdle and the surface layer and the greater thickness of the lower girdle than the bottom layer can enhance the fit of the upper girdle, lower girdle and the skin.
[0015] In some embodiments, the width of the floating girdle is 0.8 cm - 1.5 cm. The width of the floating girdle being 0.8 cm - 1.5 cm can further prevent side leakage.
[0016] By adopting the above technical solutions, the beneficial effects of the present utility model are:
[0017] 1. The utility model is provided with suspended guards on both sides of the surface layer, which are recessed inward. The upper guard of the suspended guard is connected to the surface layer, and the lower guard of the suspended guard is connected to the bottom layer. The opening is between the upper guard and the lower guard, so that the upper guard is suspended, which can effectively prevent the occurrence of menstrual blood leakage.
[0018] 2. The utility model is provided with a plurality of diversion grooves on the surface layer to form multiple drainage and diversion functions, which improves the diffusion length, increases the transmission speed, can promote the rapid and dispersed absorption of menstrual blood, avoids the occurrence of side leakage caused by unsmooth concentrated absorption, and at the same time reduces the contact time between menstrual blood and the skin, improving the absorption efficiency and dryness.
