Description

Technical Field

[0001] The utility model relates to the field of disposable sanitary products, in particular to a pair of disposable underwear with leakage-proof peripheries. Background Art

[0002] A sanitary napkin is a polymer and polymer composite paper formed by cotton, non-woven fabric, pulp or a composite of the above materials, and is mainly used as a sanitary product for women during menstruation. The existing sanitary napkin structure usually does not have a leakproof structure, especially the front and rear end leakproof structure. The Chinese patent shown in the authorization announcement number CN 220025397U is a sanitary napkin product solution with a leakproof function, which is specifically a suspended core structure sanitary napkin, including a leakproof bottom film and an absorbent core; there is a bonding portion between the absorbent core and the leakproof bottom film, and the bonding portion is an I-shaped bonding portion, and the bonding portion includes end bonding sections respectively arranged at the front and rear of the absorbent core and a middle bonding section arranged between the two end bonding sections; the width of the middle bonding section is smaller than the width of the absorbent core. The main means of preventing leakage is to change the bonding structure between the absorbent core and the bottom leak-proof bottom film, and adjust the specific bonding position of the bonding part to form a leak-proof structure; however, when the amount of body fluid is large, the absorbent core often cannot absorb it in time, and the leak-proof effect cannot be guaranteed by relying solely on the adsorption effect of the absorbent core. Utility Model Content

[0018] The following will describe the implementation methods of the present invention in detail in conjunction with specific embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0019] Embodiment 1

[0020] refer to Figure 1 and Figure 2A four-sided leak-proof disposable underwear, comprising a main body 1 formed by cutting a sheet, an absorbent core 2 is arranged on the main body 1, the length direction of the main body 1 is defined as the longitudinal direction, the width direction is defined as the transverse direction, the main body 1 is divided into a front sheet 1a, a crotch area 1b and a back sheet 1c in the longitudinal direction, and the structure is different from the traditional sanitary napkin structure. The absorbent core 2 is attached to the main body 1 during production, and the structure of the wing is omitted. The peripheral side of the absorbent core 2 is pressed or ultrasonically welded and fixed on the main body 1 to form a pressed portion 21 surrounding the peripheral side of the absorbent core 2. The core 22 of the core 2 is located in the pressing part 21; and the three-dimensional guard 23 is symmetrically arranged on the absorbent core 2, and the three-dimensional guard 23 extends along the longitudinal direction of the body 1, and extends from the crotch area 1b to the front sheet 1a and the back sheet 1c on both sides, and the three-dimensional guard 23 is bonded to the lateral sides of the core 22, and the structure adopts the traditional structure with elastic parts, which can form a vertical partition structure to prevent side leakage on the left and right sides after the product is worn; and the three-dimensional guard 23 can also adopt the three-dimensional anti-leakage part structure shown in the applicant's prior application CN217186771 U;

[0021] The front piece 1a and the back piece 1c are both provided with front and rear end leak-proof sheets 24 for preventing front and rear leakage, and the front and rear end leak-proof sheets 24 are covered on the longitudinal ends of the three-dimensional protective enclosure 23; specifically, the front and rear end leak-proof sheets 24 and the longitudinal ends of the three-dimensional protective enclosure 23 are fixedly connected to each other; such a structure, on the basis of an absorbent core 2 for absorbing liquid, is provided with front and rear end leak-proof sheets 24 with a certain liquid absorbing effect on the front piece 1a and the back piece 1c, and the front and rear end leak-proof sheets 24 are covered and located at the upper end of the absorbent core 2 to form another absorption structure higher than the absorbent core 2, thereby increasing the liquid absorption amount of the entire product on the basis of increasing the thickness here, and performing a structural design for front and rear leakage in the form of adding a liquid absorbing component; the basic structure here is to use commercially available hydrophilic sheets as the front and rear end leak-proof sheets 24.

[0022] The present technical solution improves upon the conventional sanitary napkin product and designs a trouser-type product with a preset absorbent core 2. A three-dimensional guard 23 structure that is only found on conventional diaper products is added to the absorbent core 2 structure of the product, and the three-dimensional guard 23 is used to achieve the product's function of preventing side leakage at both ends. Furthermore, front and rear end leak-proof sheets 24 that cover both ends of the three-dimensional guard 23 are added to the three-dimensional guard 23. In combination with the three-dimensional guard 23, the front and rear end leak-proof sheets 24 can form a surrounding leak-proof function centered on the absorbent core 2.

[0023] On the basis of the above, the front and rear end leakproof sheets 24 can also adopt a traditional multi-layer liquid-absorbing sheet structure, that is, a three-layer sheet structure consisting of a water-repellent bottom layer, a liquid-absorbing layer and a hydrophilic surface layer stacked in sequence from bottom to top. In this way, the thickness of the front and rear end leakproof sheets 24 can be further increased, and the liquid absorption capacity of this structure can be guaranteed, so as to further improve the effect of preventing front and rear leakage.

[0024] Embodiment 2

[0025] refer to Figure 3 , Figure 4 Compared with the first embodiment, the front and rear end leakproof sheets 24 are not fixedly connected to the longitudinal ends of the three-dimensional guard 23; here, since the front and rear end leakproof sheets 24 are not fixedly connected to the three-dimensional guard 23, a fixed connection end 24a and a non-connected free end 24b are formed between the front and rear end leakproof sheets 24 and the body 1. On this basis, the front and rear end leakproof sheets 24 are commercially available water-repellent sheets. When the three-dimensional guard 23 is erected, the front and rear end leakproof sheets 24 form water-repellent isolation barriers covering the longitudinal ends of the three-dimensional guard 23, forming a leakproof structure at the longitudinal front and rear ends;

[0026] The front and rear end leak-proof sheets 24 of this embodiment are different from the hydrophilic sheet of the first embodiment, and are water-repellent, so as to add liquid barriers at the front and rear ends of the product; the design can be changed according to the different needs of the target groups, and it has good versatility and is more suitable for use by different groups of people.

[0027] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
