Description

Technical Field

[0001] This utility model relates to the field of underwear manufacturing technology, and in particular to an underwear-type sanitary product with a replaceable absorbent core. Background Technology

[0002] Regular underwear has a relatively simple structure, usually made of one or more pieces of fabric cut and sewn together, mainly including the waistband, body, and crotch. However, its ability to absorb secretions or excretions is limited, and it mainly relies on external hygiene products such as sanitary napkins and panty liners to keep the skin dry. Utility Model Content

[0003] The present invention aims to provide an underwear-style sanitary product with a replaceable absorbent core to overcome or at least partially solve the above-mentioned problems.

[0004] To achieve the above objectives, the technical solution of this utility model is specifically implemented as follows:

[0005] This utility model provides a panty-style sanitary product with a replaceable absorbent core, including a panty body. The panty body includes an outer covering layer, a middle leak-proof layer, and an absorbent core layer. The middle leak-proof layer is connected to the inner side of the outer covering layer, and the absorbent core layer is connected to the inner side of the middle leak-proof layer.

[0006] The intermediate leak-proof layer includes a pure cotton knitted fabric layer and a polyurethane film layer. The polyurethane film layer is disposed on the lower side of the pure cotton knitted fabric layer and is bonded to the inner side of the outer covering layer.

[0007] The absorbent core layer includes a fabric surface layer, a blood-absorbing sponge layer, a bottom layer, and a Velcro closure. The blood-absorbing sponge layer is located on the underside of the fabric surface layer, and the bottom layer is located on the underside of the blood-absorbing sponge layer. The blood-absorbing sponge layer is placed between the fabric surface layer and the bottom layer. The bottom layer has a Velcro closure on its underside, and the underside of the Velcro closure is connected to the pure cotton knitted fabric layer through a hook face.

[0008] As a further embodiment of this utility model, the transverse and longitudinal tensile ratios of the outer covering layer are greater than 1 and less than or equal to 5.

[0009] As a further embodiment of this invention, the Velcro fastener of the absorbent core layer is fixed to the bottom layer by means of hot melt adhesive bonding layer.

[0010] As a further embodiment of this utility model, the pure cotton knitted fabric layer and the polyurethane film layer of the intermediate leak-proof layer are fixed by a hot melt adhesive bonding layer two by applying adhesive.

[0011] As a further embodiment of this utility model, the polyurethane film layer of the intermediate leak-proof layer and the outer covering layer are fixed by a hot melt adhesive bonding layer three by applying adhesive.

[0012] As a further embodiment of this utility model, the hook side of the Velcro is attached to the pure cotton knitted fabric layer for fixation between the absorbent core layer and the intermediate leak-proof layer.

[0013] As a further embodiment of this utility model, the absorbent core layer in the underwear body is separate and can be configured according to the user's own situation during use. Before use, a layer of non-woven fabric is attached to the Velcro on the underwear body to prevent the Velcro from sticking to the underwear body itself.

[0014] As a further embodiment of this invention, the blood-absorbing sponge layer includes a long strip-shaped core with a central protrusion, which can be embedded inside the user's body to effectively absorb and block the outflow of menstrual blood.

[0015] As a further embodiment of this invention, the absorbent core layer is attached to the intermediate leak-proof layer with adhesive backing.

[0016] This utility model provides an underwear-style sanitary product with a replaceable absorbent core, which has the following advantages:

[0017] Replaceable underwear has a unique structure, including the underwear body and a replaceable core;

[0018] The main design of the underwear is similar to that of regular underwear, focusing on comfort and fit. It uses soft, breathable fabric to provide a good feel against the skin and allow it to fit more closely to the wearer's skin.

[0019] The design of the core varies depending on different functional requirements. The shape and size of the core are adapted to the crotch area of ​​the underwear, and it can be easily installed and removed.

[0020] The outer layer of the fabric has good moisture absorption, breathability and quick-drying properties, making it comfortable against the skin and relatively friendly to sensitive skin; the blood-absorbing sponge layer has good blood-absorbing properties, which can absorb and lock in blood to ensure the overall dryness of the underwear; the polyurethane film layer can prevent blood from seeping into the external environment and provide additional leak protection.
