Description

Technical Field

[0001] This utility model relates to the field of absorbent articles, and in particular to an absorbent article in the form of openable underwear. Background Technology

[0002] Among absorbent items, pull-up diapers, with their numerous elastic bands at the waist, offer a better fit compared to disposable diapers, ensuring a more secure and stable fit during movement. For added ease of wear, the waistband is tear-open and features a fastening buckle to secure the waist and prevent it from slipping off.

[0003] An existing design, such as the absorbent article disclosed in Chinese patent CN218852958U, includes a crotch area, a front waist area and a back waist area extending upward from the crotch area. Side sealing portions are provided on both sides of the front and back waist areas to seal them together, forming a closed ring-shaped waist structure. Fastening components with free ends that can be attached to the front or back waist areas are also provided on the side sealing portions. The fastening components employ hook-and-loop fasteners and hook-and-loop structures located at the free ends of the fasteners. The hook-and-loop fasteners are mostly made of non-woven fabric, lack elasticity, have a small adjustment range, and affect the fit. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an absorbent underwear-type garment with a clasp fastening piece that offers a wide range of adjustment and a good fit.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] This open-type absorbent underwear includes a waist area and a crotch area. The crotch area is provided with an absorbent body, and the waist area is provided with a fastening fastener for tightening the waist. The fastening fastener is provided with a fastener and is made of elastic material. The fastening fastener area on the elastic material fastener corresponding to the fastener is a spring-loaded area.

[0007] Further:

[0008] The fastener has a fixed end and a free end, with the fastener positioned between the fixed end and the free end. The area between the fixed end and the fastener is an elastic area.

[0009] The elastic material fixing sheet is an elastic sheet that is elastic at least in the lateral direction.

[0010] The area between the buckle and the free end is the handle area, which is a spring-absorbing area or an elastic embossed area.

[0011] The elastic sheet material includes a non-woven composite structure and an elastic band embedded in the non-woven composite structure; the fastener is a magic hook.

[0012] The bullet-dissipating area is either a vertical bullet-dissipating area or an oblique bullet-dissipating area.

[0013] The elastic embossed area is a composite area formed by embossing on an elastic material.

[0014] The buckle extends longitudinally to the upper and lower edges of the buckle fastening piece.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This open-loop type absorbent underwear is reasonably designed. The fastener is made of elastic material and has been treated to absorb excess elasticity in the fastener area. When the waistband is tightened, the fastener has lateral elasticity, resulting in a better fit and making it suitable for a wider range of people. Attached Figure Description

[0034] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0035] like Figures 1 to 13 As shown, the openable underwear-type absorbent article 1 includes a waist area and a crotch area C; the waist area includes a front waist area and a back waist area, the two sides of the front waist area A and the back waist area B are joined by a side seal 6, and an easy-tear line 2 for easy opening is provided near the side seal of the front waist area A or the back waist area B.

[0036] The crotch area C is equipped with an absorbent body, and the waist area is equipped with a buckle fastening piece 5 for tightening the waist. The buckle fastening piece is equipped with a buckle 4. The buckle fastening piece is an elastic material fastening piece, and the buckle fastening area on the elastic material fastening piece corresponding to the buckle is the elastic damping area E.

[0037] The snap fastener of this absorbent item is made of elastic material and has been treated to eliminate elasticity in the snap fastener area. When the waistband is tightened, the snap fastener has lateral elasticity 'a', resulting in a better fit and making it suitable for a wider range of people.

[0038] The fastener 5 has a fixed end and a free end. The fixed end of the fastener is sealed and fixed together with the waist edge. Preferably, the fixed end of the fastener is fixed on the edge of the front waist area A. The front waist area is provided with an easy-tear line cut 3 near the edge, thereby forming an easy-tear line 2.

[0039] The fastener is positioned between the fixed end and the free end, and the area between the fixed end and the fastener is the elastic region D. The elastic material fastener is an elastic sheet that is elastic at least in the transverse direction; preferably, it is an elastic sheet with transverse elasticity; the elastic sheet includes a non-woven composite structure and an elastic band composited within the non-woven composite structure; in addition, materials such as elastic film and elastic non-woven fabric can also be used; the fastener 4 is a magic hook.

[0040] The hooks and latches can be fixed together by adhesive, hot pressing, ultrasonic bonding or other methods; the hooks extend longitudinally to the upper and lower edges of the latches, and the structure is reliable.

[0041] Preferably, the elastic sheet comprises an outer nonwoven fabric I 101, an inner nonwoven fabric 102, an elastic band 103, a front waistband middle nonwoven fabric 104, a middle nonwoven fabric fixing adhesive 105, a middle nonwoven fabric reinforcing fixing adhesive 106, and an outer nonwoven fabric II 107, which are sequentially laminated to form a sheet that is at least elastic in the transverse direction.

[0042] like Figures 6 to 13 As shown, the area between the fixed end and the buckle on the elastic material fixing piece is the elastic area D. The lateral elasticity of this area is ensured by the elasticity of the elastic material fixing piece itself, and no elasticity reduction treatment is performed in this area.

[0043] The area on the elastic material fixing piece corresponding to the buckle is the spring-reducing area E, which is treated to reduce spring tension. The area between the buckle and the free end is the handle area F, which is either the spring-reducing area or the elastic embossed area.

[0044] Preferably, the de-elasticity area is a vertical de-elasticity area or an oblique de-elasticity area; the elastic embossing area is a composite area formed by embossing on an elastic material.

[0045] Figures 6 to 12 A method for forming a retaining plate with elastic material in the CD direction on the retaining plate body; Figure 13 The fixing plate is formed by setting an elastic material fixing plate in the MD direction on the fixing plate body; after the buckle completes local elasticity absorption in regions E and F, multiple discrete buckles are formed by circumferential cutting, which are fixed on both sides of the absorbent material of the openable underwear and form elasticity in region D. It should be noted that the aforementioned MD direction is... Figure 2 The horizontal direction 'a' shown is consistent with the horizontal direction 'a', and the CD direction is perpendicular to the MD direction.

[0046] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.

[0047] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
