Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkins, in particular to a multi-layer leak-proof sanitary napkin. Background Art

[0002] Sanitary napkins mainly consist of three layers: a surface layer, an absorbent core, and a bottom layer. The layers of material are bonded together with hot-melt adhesive. During use, the sanitary napkin will take on different shapes as the human body moves in different states, and will be squeezed during use. Although the sanitary napkin is provided with a high-efficiency gel layer inside the absorbent core, which can condense the infiltrated liquid into a gel-like state and prevent it from seeping back after being compressed, the local absorption capacity of the high-efficiency gel layer is limited. When too much liquid enters the local high-efficiency gel layer, the high-efficiency gel layer cannot condense the excessive liquid in time. These small amounts of liquid that fail to condense in time are easily squeezed out from the infiltration holes on the surface layer and leak out through the sides when the absorbent core inside the sanitary napkin is squeezed during human movement. For this reason, we have made improvements to this and proposed a multi-layer leak-proof sanitary napkin. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a multi-layer leak-proof sanitary napkin, which can effectively prevent the leakage of liquid caused by squeezing while absorbing liquid.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a multi-layer leak-proof sanitary napkin, including a sanitary napkin body, which is provided with a skin-friendly layer, a breathable layer, an absorbent layer and a leak-proof layer from top to bottom, wings are provided on both sides of the sanitary napkin body, and a skin-friendly patch is also provided at the edge of the sanitary napkin body, and the skin-friendly patch and the sanitary napkin body are matched through an elastic support structure.

[0005] Optionally, the skin-friendly layer, breathable layer, absorbent layer and leak-proof layer are connected by viscose hot-pressing composite connection, which facilitates stacking production.

[0006] Optionally, an adhesive sheet is provided at the bottom of the protective wing, and a transparent tear strip for protection is provided on the outside of the adhesive sheet. The transparent tear strip can protect the adhesive sheet, and the adhesive sheet can fix the protective wing.

[0007] Optionally, the breathable layer is a silicone layer, and the outer wall of the breathable layer is provided with a plurality of breathable holes. The silicone layer is more comfortable and softer, and the breathable holes can be used for ventilation to improve comfort.

[0008] Optionally, the skin-friendly layer is further embossed with guide lines, which facilitate the introduction of liquid into the absorption layer for absorption.

[0009] Optionally, the elastic support structure includes a sponge layer filled between the skin-friendly patch and the sanitary napkin body, and elliptical rubber particles arranged in the sponge layer. The elliptical rubber particles can provide support and at the same time separate the skin-friendly patch and the sanitary napkin body. The liquid cannot overflow and can only flow between the skin-friendly patch and the sanitary napkin body.

[0010] The utility model provides a multi-layer leak-proof sanitary napkin, which has the following beneficial effects:

[0011] This multi-layer leak-proof sanitary napkin is provided with a skin-friendly layer, a breathable layer, an absorbent layer, a leak-proof layer, a skin-friendly patch and an elastic support structure. The skin-friendly layer can improve comfort. When in use, the breathable layer can have a breathable effect to improve comfort. The leak-proof layer can effectively prevent liquid leakage. At the same time, under the action of the elastic support structure, a gap is generated between the skin-friendly patch and the skin-friendly layer. Even if liquid overflows, it will be absorbed by the sponge layer in the elastic support structure, reducing the risk of overflow from the side. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 4 The utility model provides a technical solution: a multi-layer leak-proof sanitary napkin, comprising a sanitary napkin body 1, which is provided with a skin-friendly layer 11, a breathable layer 12, an absorbent layer 13 and a leak-proof layer 14 from top to bottom, wings 2 are provided on both sides of the sanitary napkin body 1, and a skin-friendly patch 3 is also provided at the edge of the sanitary napkin body 1, and the skin-friendly patch 3 is matched with the sanitary napkin body 1 through an elastic support structure 4.

[0020] As a preferred embodiment, on the basis of the above method, the skin-friendly layer 11, the breathable layer 12, the absorption layer 13 and the leakage-proof layer 14 are further connected by viscose hot pressing composite connection. The skin-friendly layer 11, the breathable layer 12, the absorption layer 13 and the leakage-proof layer 14 are conveniently stacked and produced by viscose hot pressing composite connection. The skin-friendly layer 11 is non-woven fabric and the absorption layer 13 is resin.

[0021] An adhesive sheet is provided at the bottom of the protective wing 2, and a transparent tear strip for protection is provided on the outside of the adhesive sheet. The transparent tear strip can protect the adhesive sheet, and the adhesive sheet can fix the protective wing 2.

[0022] The breathable layer 12 is a silicone layer, and the outer wall of the breathable layer 12 is provided with multiple breathable holes 15. The silicone layer is more comfortable and softer. The breathable holes 15 can be used for ventilation to improve comfort. The skin-friendly layer 11 is also embossed with guide lines 16, which facilitate the introduction of liquid into the absorption layer 13 for absorption.

[0023] As a preferred embodiment, on the basis of the above method, the elastic support structure 4 further includes a sponge layer 41 filled between the skin-friendly patch 3 and the sanitary napkin body 1, and elliptical rubber particles 42 arranged in the sponge layer 41. The elliptical rubber particles 42 can play a supporting role. At the same time, the elliptical rubber particles 42 can also separate the skin-friendly patch 3 and the sanitary napkin body 1, so that the liquid cannot overflow and can only flow between the skin-friendly patch 3 and the sanitary napkin body 1.

[0024] In summary, when using the multi-layer leak-proof sanitary napkin, the transparent tear strip on the wing 2 is removed, and then the sanitary napkin body 1 is fixed with the adhesive sheet. At this time, the skin-friendly patch 3 and the skin-friendly layer 11 are in contact with the skin, and the skin-friendly layer 11 can improve the comfort. When in use, the breathable layer 12 can play a breathable effect and improve the comfort. The absorption layer 13 is used to absorb liquid, and the leak-proof layer 14 can effectively prevent liquid leakage. At the same time, under the action of the elastic support structure 4, a gap is generated between the skin-friendly patch 3 and the skin-friendly layer 11. Even if liquid overflows, it will be absorbed by the sponge layer 41 in the elastic support structure 4, reducing the risk of overflow from the side.

[0025] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
