DETAILED DESCRIPTION

[0021] The embodiment of the present utility model provides a uterine-warming sanitary napkin, which will be further described below with reference to the accompanying drawings.

[0022] Please refer to the attached Figure 1-3 The embodiment of the present application provides a uterine warming sanitary napkin, comprising a body 40, wherein the body 40 is generally in the shape of a strip sheet, including a length direction and a width direction. Figure 1 The length direction is the up-down direction, and the width direction is the left-right direction. The main body 40 includes a first portion 10, a connecting portion 20 and a second portion 30 along the length direction.

[0023] In this embodiment, the first part 10 is usually attached to the underwear for absorbing menstrual blood. The second part 30 can be attached to the underwear together with the first part 10 or attached to the skin alone for heating the uterus to form a warm uterus effect. The connecting part 20 is arranged between the first part 10 and the second part 30, and connects the first part 10 and the second part 30. It can be understood that the first part 10 can also include a three-dimensional guard to prevent side leakage of menstrual blood, and the first part 10 can further include wings. The wings are usually located on the left and right sides of the main absorption area of the first part 10. Usually, the wings protrude from the main body 40 and can be folded back to more stably fix the first part 10 to the underwear. The main absorption area refers to the area on the first part 10 corresponding to the body fluid discharge area, and the body fluid discharge area can be a vaginal opening, urethral opening and other positions.

[0024] The main body 40 includes a stacked surface layer 11 and a bottom layer 12, wherein the surface layer 11 is arranged on the side close to the user's skin, and the surface layer 11 should be at least partially liquid-permeable. The meaning of liquid-permeable is that body fluids can pass through the surface layer 11 into the structural layer below the surface layer 11, such as the absorption layer. Usually, the body fluids can also diffuse along the surface layer 11 to further improve the absorption efficiency of the absorbent body for body fluids. The at least partially liquid-permeable means that at least the area corresponding to the surface layer 11 and the main absorption area is liquid-permeable.

[0025] Since the surface layer 11 contacts the skin, it is preferred to use a low-irritation, soft material, such as a material with a unit area weight of 10 to 60 g / m 2 The sheet materials include gauze, cotton, spunlace non-woven fabric, hot air non-woven fabric and the like, more preferably, hot air non-woven fabric composed of thermoplastic synthetic fibers, as the synthetic fibers constituting the above-mentioned hot air non-woven fabric, polyolefin fibers such as polyethylene (PE) fiber and polypropylene (PP) fiber, polyester fibers, polyamide fibers such as nylon, etc. can be used, in some optional embodiments, natural fibers or viscose fibers can also be added at the same time to further reduce irritation to the skin, these natural fibers can include wood fibers, cotton fibers, etc.

[0026] The bottom layer 12 is arranged below the surface layer 11. In order to prevent body fluids from passing through the surface layer 11 and contaminating the user's clothes, the bottom layer 12 is usually made of a water-repellent material. Specifically, it can be a PE film, SMS non-woven fabric, non-woven fabric with a water-repellent surface treatment, etc. In this embodiment, the bottom layer 12 should be an airtight material or a material that is breathable in some areas. More specifically, the bottom layer 12 is breathable in the area corresponding to the first part 10 and is airtight in the area corresponding to the second part 30.

[0027] The surface layer 11 and the bottom layer 12 are arranged in the first part 10 to form a first space 100. The first space 100 contains an absorbent core 13. The absorbent core 13 is formed by a plurality of fibers entangled and appropriately connected to form a three-dimensional network structure. A plurality of pores are distributed between the three-dimensional network structures, and body fluids can be absorbed and diffused through these pores. In a preferred embodiment, a polymer water-absorbing material (SAP) is included between the three-dimensional network structures to further absorb and retain body fluids through the polymer water-absorbing material. It can be understood that the fibers can be fluff pulp.

[0028] It can be understood that the surface layer 11 and the bottom layer 12 are combined along the outer side of the first space 100 to form a first peripheral joint part 101, and the surface layer 11 and the bottom layer 12 are formed into a whole through the first peripheral joint part 101, so that the first space 100 enclosed by the surface layer 11 and the bottom layer 12 is a closed space. The combination refers to the connection of the combined materials to form a whole, which can usually be formed by hot melting or bonding. The hot melting can be achieved by heating the material itself to reach the melting point temperature, locally melting it, and forming a connection after solidification, or by external energy such as ultrasound acting on the material to cause the material to melt locally at high temperature, and forming a connection after solidification. The bonding can be achieved by using an adhesive to connect adjacent materials under the action of the adhesive.

[0029] The surface layer 11 and the bottom layer 12 are combined at the connecting portion 20 to form an intermediate joint 22. The surface layer 11 and the bottom layer 12 are surrounded by the second portion 30 to form a second space 300. More specifically, the surface layer 11 and the bottom layer 12 are combined at the second portion 30 along the periphery of the second space 300 to form a second peripheral joint 301. The surface layer 11 and the bottom layer 12 are formed into a whole through the second peripheral joint 301, so that the second space 300 surrounded by the surface layer 11 and the bottom layer 12 is also a closed space. It can be understood that the intermediate joint separates the first space 100 and the second space 300, that is, the first space 100 and the second space 300 are independent spaces that are not connected.

[0030] The second space 300 contains a self-heating material 31, which can be a mixture of powders such as iron powder and carbon powder. In a specific embodiment, the self-heating material 31 can also include fillers such as zeolite, vermiculite, and diatomaceous earth. In order to ensure that the self-heating material 31 can be stably fixed in the second space 300, the upper side of the self-heating material 31 is also covered with an isolation layer 32. The isolation layer 32 is combined with the bottom layer 12 to form a plurality of strip spaces 320. The self-heating material 31 is accommodated in the strip spaces 320. In this way, on the one hand, the self-heating material 31 can be stably fixed in the second space 300, on the other hand, the height of the self-heating material 31 can be reduced, reducing the impact of the self-heating material 31 on the comfort of use, and on the third hand, the self-heating material 31 can be kept away from the skin, thereby reducing the rate at which the self-heating material 31 rises in temperature, thereby improving the comfort of use.

[0031] Furthermore, the length direction of the strip-shaped space 320 is parallel to the length direction of the body 40 .

[0032] Furthermore, multiple strip spaces 320 are arranged in parallel and spaced apart along the width direction of the main body 40, so that these strip spaces 320 with built-in self-heating materials 31 can be easily bent along the width direction of the main body 40, so that the second part 30 can be stably fixed on the skin.

[0033] Furthermore, in the second space 300, a functional layer 33 is provided between the surface layer 11 and the isolation layer 32. The functional layer 33 includes a functional material. The functional material includes a volatile material or a sustained-release material. In a specific embodiment, the functional material can be a Chinese medicinal material, more specifically, Chuanxiong powder, etc. In another embodiment, the functional material can be an essence.

[0034] It can be understood that when the self-heating material 31 generates heat, the volatile components or slow-release components in the functional material can be released faster through the surface layer 11, thereby improving the uterine warming effect.

[0035] The second part 30 also includes an adhesive layer 35 arranged on the surface layer 11 in a ring shape around the second space 300 and a peeling sheet 34 attached to the adhesive layer 35. The peeling sheet 34, adhesive layer 35 and bottom layer 12 seal the second space 300. It can be understood that by sealing the second space 300 through the peeling sheet 34, adhesive layer and bottom layer 12, the self-heating material 31 located in the second space 300 can be kept isolated from oxygen, thereby preventing the self-heating material 31 from self-heating under unexpected circumstances.

[0036] It can be understood that the peeling sheet 34 is peelably attached to the adhesive layer 35. When the peeling sheet 34 is peeled off from the adhesive layer 35 under the action of external force, the second space 300 is connected to the outside world through the pores of the surface layer 11, so that the self-heating material 31 in the second space 300 contacts oxygen for self-heating.

[0037] Furthermore, in order to make the peeling sheet 34 easily peelable from the adhesive layer 35 , a silicone oil layer is provided on the side of the peeling sheet 34 facing the adhesive layer 35 .

[0038] Furthermore, the silicone oil layer is only provided corresponding to the adhesive layer 35 .

[0039] Furthermore, the adhesive layer 35 includes hydrogel, so that the second part 30 can be conveniently attached to the skin through the hydrogel.

[0040] Furthermore, on the outside of the adhesive layer 35, the second part 30 also includes an edge pressing groove 36, and the edge pressing groove 36 includes a groove recessed from the outer surface of the peeling sheet 34 toward the surface layer 11. The peeling sheet 34 is combined with the surface layer 11 through the edge pressing groove 36 to further form a sealing area. At the same time, this method will not cause the peeling sheet 34 to form a fixed connection with the surface layer 11, and the peeling sheet 34 can still be separated from the surface layer 11 under the action of external force.

[0041] Furthermore, the adhesive layer 35 is disposed directly above the second peripheral joint portion 301 so that the surface layer 11 will not be damaged when the peeling sheet 34 is peeled off by an external force.

[0042] Furthermore, the peeling sheet 34 further includes a peeling end 341 , and the peeling end 341 is separately provided from the surface layer 11 , so that the user can conveniently peel off the peeling sheet 34 by clamping the peeling end 341 .

[0043] The connecting portion 20 is also provided with a tear line 21 along the width direction, which is used to separate the second part 30 from the main body 40 under the action of external force. Specifically, the tear line 21 can be formed by punching a hole in the connecting portion 20. More specifically, a plurality of through holes are intermittently provided along the width direction of the connecting portion 20, so that the tear line 21 is formed in the direction in which the through holes continue.

[0044] Furthermore, the peeling end 341 faces the connecting portion 20 , and covers the tear line 21 .

[0045] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
