[0022] 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.
[0023] Embodiment 1
[0024] refer to Figures 1 to 3 , a front and back close-fitting absorbent article, comprising a body formed by cutting a sheet, an absorbent core is arranged on the body, the length direction of the body is defined as the longitudinal direction, the width direction is defined as the transverse direction, the body is divided into a front piece, a crotch area and a back piece in the longitudinal direction, and a three-dimensional guard is symmetrically arranged on the absorbent core, the three-dimensional guard extends in the longitudinal direction of the body, and extends from the crotch area to both sides to the front piece and the back piece; wherein the three-dimensional guard 23 adopts a structure of a traditional strip sheet wrapped with spandex yarn, and can also adopt the three-dimensional leak-proof part structure shown in the applicant's prior application CN217186771 U;
[0025] Furthermore, the front and rear end leak-proof sheets are provided on the front and rear pieces for preventing front and rear leakage, and the front and rear end leak-proof sheets have mutually fixed connection ends and non-fixed free ends with the front and rear pieces, and elastic parts are embedded in the free ends. The free ends are covered with free end covers above the longitudinal ends of the three-dimensional protective enclosure, and when the absorbent article is worn, the free ends are lifted and fit to the user by the action of the three-dimensional protective enclosure and the elastic parts. The technical solution pre-installs the absorbent core during the production process, and three-dimensional guardrails are arranged on the two lateral sides of the absorbent core to prevent leakage on the left and right sides. Front and rear end leak-proof sheets are added on the front and rear sides to achieve four-way leak-proofing, and the front and rear end leak-proof sheets are arranged near the crotch area and cover the ends of the three-dimensional guardrails. In this way, when worn, the three-dimensional guardrails can be stood up and the elastic parts in the front and rear end leak-proof sheets can be used to lift the free end parts of the front and rear end leak-proof sheets as a whole to fully fit the human body, thereby ensuring the leak-proofness of the front and rear ends. As the elastic parts retract, the front and rear end leak-proof sheets will form wrinkles extending in the longitudinal direction. Compared with thin sheet materials, the softness of the front and rear end leak-proof sheets in contact with the human body is improved to avoid excessive friction and affect comfort.
[0026] In this embodiment, the elastic member is arranged at the edge of the front and rear end leakage-proof sheet near the center of the body and extends in the transverse direction; the elastic member is made of spandex, which is the basic raw material in the production of traditional sanitary products; and is distributed in a straight line in the transverse direction, which is convenient for application in production, and when retracted, the width of the edge of the front and rear end leakage-proof sheet is reduced, and cooperates with the three-dimensional guard, and the opening formed between the two is reduced as the elastic member retracts, forming a sufficient wrapping of the four sides of the absorbent core;
[0027] In this embodiment, the front and rear end leak-proof sheets are water-repellent sheets to form liquid barriers at the front and rear ends of the product; accordingly, when the product is used in a scenario where the liquid absorption pressure is relatively small, the front and rear end leak-proof sheets can also be set as hydrophilic liquid-absorbent sheets to form another absorption component located at the front and rear ends;
[0028] In this embodiment, the two lateral sides of the main body are welded and fixed to form a trouser-type structure; this trouser-type structure is formed during production, and the product is designed as a trouser-type with a preset absorbent core when it leaves the factory. During use, it can be used as disposable underwear or menstrual pants with a certain absorption effect; and the waist structure during molding can be as shown in the applicant's prior application CN 219847103 U, which has a small-sized tiny weld to ensure the comfort of the welding position.
[0029] On the contrary, it can also be set as a flexible wearing and taking off structure according to different products, that is, magic buckles are provided on the lateral sides of the main body for forming a trouser-shaped structure when worn. When this is applied to disposable underwear, it can be directly replaced without taking off the outer pants, which improves the flexibility of the product when used.
[0030] Embodiment 2
[0031] refer to Figure 4 Compared with the first embodiment, the elastic member is arranged in an arc shape, extending inward from the edge of the front and rear end leakproof sheets. Specifically, the edge of the front and rear end leakproof sheets close to the center of the product is an arc-shaped concave structure extending outward. On the premise of ensuring that the opening formed between the front and rear end leakproof sheets and the three-dimensional guard are gathered together, the size of this opening is increased, so that the body fluid can fall onto the absorbent core as much as possible in different body positions of the human body, thereby ensuring the absorbency.
[0032] Embodiment 3
[0033] refer to Figure 5 Compared with the first and second embodiments, it is another design idea: that is, the elastic member is arranged in an arc shape, extending from the center to the edge of the front and rear end leakproof sheets; under this structure, the edge of one side of the front and rear end leakproof sheets close to the center of the product is an arc-shaped convex structure extending outward, so that when the elastic member is retracted, this convex structure can increase the size of the free end and reduce the size of the opening formed between the front and rear end leakproof sheets and the three-dimensional guardrail. The desired effect is to increase the height of the front and rear end leakproof sheets when standing up, thereby ensuring the barrier effect of the front and rear ends; secondly, to form a long wrinkle at the position of this convex structure, increase the contact length of this position with the human body, so as to further improve the fit. Although the utility model is specifically demonstrated and introduced in conjunction with the preferred embodiment, technicians in the relevant field should understand that various changes can be made to the utility model in form and details without departing from the spirit and scope of the utility model defined by the attached claims, all of which are within the scope of protection of the utility model.
