Description

Technical Field

[0001] This utility model relates to the field of sleeping pants technology, specifically to a disposable, seamless menstrual underwear. Background Technology

[0002] Overnight panties are sanitary products for women, suitable for use at night during menstruation. Because overnight panties have a high absorbency, wearing them can solve the problem of frequently changing sanitary pads at night. At the same time, compared with sanitary pads, overnight panties can also solve the problem of menstrual blood leakage at night. Therefore, overnight panties are favored by many women.

[0003] For example, Chinese patent (application number: 202220659785.3) discloses a breathable sleeping pants, including a pant body with a bottom layer and a top layer. An absorbent core is located in the crotch area of ​​the pant body between the bottom layer and the top layer. The bottom layer of the pant body is made of water-repellent non-woven fabric, and multiple leak-proof layers are provided between the water-repellent non-woven fabric in the crotch area and the absorbent core. Although this sleeping pants can improve the comfort of use, it requires Velcro or snaps to wear and fix the sleeping pants. This design will form a hard block area in the waist and abdomen area during wear, causing discomfort when turning to the side or bending over. Moreover, this connection method requires prior alignment, which also brings inconvenience to wearing the sleeping pants. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a disposable, seamless menstrual underwear that can improve user comfort during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a disposable, seamless menstrual underwear, comprising a base material and an absorbent core disposed on the base material. The base material comprises a buttock bottom material, a crotch bottom material, and a front waist bottom material disposed sequentially. An adhesive is disposed between the buttock bottom material and the front waist bottom material. The absorbent core comprises a central body, an extension body, and an absorbent substrate disposed on the crotch bottom material. A leak-proof barrier is disposed at the edge of the extension body.

[0006] As a further improvement to the above technical solution:

[0007] The adhesive includes connectors disposed on both sides of the buttocks base material, and heat-sealing adhesive is disposed on the side wall of the connectors facing the front waist base material.

[0008] The central body, extension body, and absorbent matrix are distributed in a stepped manner from top to bottom, and their width gradually increases from top to bottom.

[0009] The edges of the central body, the extension body, and the absorbent matrix are all provided with hot-pressed sealing areas.

[0010] Each of the aforementioned hot-pressed sealed areas is provided with multiple hot-pressing breakpoints.

[0011] One end of the absorbent matrix is ​​provided with an extension area extending to the buttock base material, and a hot-pressed connection point is provided at the connection between the extension area and the absorbent matrix.

[0012] The width of the extended region gradually increases outward from the end connected to the absorber matrix.

[0013] The beneficial effects of this utility model embodiment are as follows: The disposable openable seamless menstrual underwear includes a base material and an absorbent core disposed on the base material. The base material includes a buttock bottom material, a crotch bottom material and a front waist bottom material disposed in sequence. An adhesive is disposed between the buttock bottom material and the front waist bottom material. The adhesive includes a connector integrally formed with the base material and located on both sides of the buttock bottom material. The side wall of the connector is provided with heat-sealing adhesive that connects to the front waist bottom material. When in use, it can generate adhesion according to the body temperature. During use, it can ensure that the safety pants will not fall off and the wearing method is more convenient. The heat-sealing adhesive is used for fixation. Compared with existing snaps or Velcro, there will be no hard block structure in the waist and abdomen area, which can improve the user's comfort when bending over or turning to the side.

[0014] Multiple hot-pressing breakpoints are provided in the hot-pressed sealing area at the edges of the central body, extension body, and absorbent substrate. The hot-pressing breakpoints can change the thickness of the absorbent core according to the user's individual situation and the amount of discharge during use. If the amount of discharge decreases later, the central body on the absorbent core can be torn off from the hot-pressing breakpoint to reduce the overall thickness and improve the comfort during use.

[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 1-3 As shown, the base material 1 is made of low-weight spandex fabric and cut to form a continuous safety pant shape, including a buttock bottom material 3, a crotch bottom material 4, and a front waist bottom material 5. The absorbent core 2 is then connected to the base material 1 by adhesive bonding. Adhesive parts 6 are provided on both sides of the buttock bottom material 3 to connect with the front waist bottom material 5. The adhesive parts 6 include connectors 11 integrally formed with the base material 1 and located on both sides of the buttock bottom material 3. The side wall of the connectors 11 is provided with heat-sealing adhesive 12 to connect with the front waist bottom material 5. During use, the adhesive can generate stickiness according to the body temperature, which can ensure that the safety pant will not fall off during use and the wearing method is more convenient. The heat-sealing adhesive 12 is used for fixation. Compared with existing snaps or Velcro, there will be no hard block structure in the waist and abdomen area. It can improve the user's comfort when bending over or turning to the side. Moreover, the whole product is designed for single use, which is convenient for travel and does not require washing, effectively avoiding the growth of bacteria.

[0022] During the fabrication of the absorbent core 2, the central body 7, the extension body 8, and the absorbent substrate 9 are first fabricated using cleanroom paper and SAP. These three are distributed sequentially from top to bottom in a stepped pattern, with the width gradually increasing from top to bottom. The edges of all three are sealed by heat pressing to form a heat-pressed closed area 13, which acts as a locking edge to prevent leakage in each core layer. A leak-proof barrier 10 is provided at the edge of the extension body 8 to prevent side leakage of the absorbent core 2. The leak-proof barrier 10 is composed of hot-air nonwoven fabric and wood pulp cotton strips, which has the advantages of being skin-friendly and leak-proof.

[0023] Multiple hot-pressed breakpoints 14 are provided in the hot-pressed sealing area 13 at the edges of the central body 7, the extension body 8, and the absorbent base 9. The hot-pressed breakpoints 14 can change the thickness of the absorbent core 2 according to the user's personal situation and the amount of discharge during use. If the amount of discharge decreases later, the central body 7 on the absorbent core 2 can be torn off from the hot-pressed breakpoint 14 to reduce the overall thickness of the absorbent core 2 and improve the comfort during use. An extension area 15 is provided at the end of the bottom absorbent base 9 facing the buttocks base 3. The function of the extension area 15 is to prevent leakage when sitting for a long time or at night. The connection between the front end of the extension area 15 and the absorbent base 9 is bonded by the hot-pressed connection point 16. The extension area 15 covers the buttocks base 3 in a fan shape. At the same time, an extension area with the same function can be designed on the front waist base 5 to enhance the leak-proof effect.
