Technical Field

[0001] This application relates to the technical field of absorbent articles, and more particularly to closable absorbent articles. Background Technology

[0002] Absorbent products, including absorbent sanitary products. Absorbent sanitary products refer to products that can absorb bodily secretions or blood, including sanitary napkins, panty liners, period panties, baby care products, and adult care products. With consumers' increasing demands for personal hygiene and comfort, the absorbent sanitary products market is showing a rapid growth trend.

[0003] Current absorbent products are divided into open-type and closed-type. Closed-type products, such as pull-ups, require you to take off your pants to put them on in daily use, which is inconvenient. Open-type products, such as disposable diapers, have the disadvantages of being inconvenient to adjust the waistband and having relatively poor coverage.

[0004] Therefore, it is necessary to provide absorbent materials that can be opened and closed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this application provides an openable absorbent article with the advantages of convenient wearing, easy separation, and adjustable waist size. When worn, the front waist area A is placed in front of the waist, the back waist area B is placed behind the waist, and the crotch area C covers the crotch area. It is secured with a side-sealing structure, thus forming a closed absorbent article after wearing. In use, the front waist area A and the back waist area B can be separated by tearing / opening the side-sealing structure, or by tearing / pulling the openable structure to separate the side-sealing structure, thereby separating the front waist area A and the back waist area B.

[0035] The following will clearly and completely describe the concept, specific structure, and resulting technical effects of this application in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this application. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this application can be combined interactively without contradicting each other.

[0036] Settings such as Figure 2 The absorbent article shown is defined as follows: when open, the vertical direction is longitudinal and the horizontal direction is transverse. The absorbent article includes a crotch area C with an absorbent sheet, a front waist area A extending longitudinally upward from the crotch area C, and a rear waist area B extending longitudinally downward.

[0037] like Figure 3 As described above, when wearing the garment, after the crotch area C covers the crotch, the front waist area A extends upward longitudinally, and the back waist area B extends upward longitudinally.

[0038] like Figure 1-2 The tearable absorbent material shown includes a crotch area C, a front waist area A extending forward and backward from the crotch area C, and a back waist area B.

[0039] The front waist region A and the rear waist region B are provided with side sealing structures 1 on both sides, which can fix the front waist region A and the rear waist region B to form a closed ring waist structure, and can separate the front waist region A and the rear waist region B to be open. The side sealing structure 1 includes a fixing part 11 or an adhesive part 12.

[0040] Specifically, in this application, the front waist area A is used to cover the user's front waist area when worn, providing a suitable coverage area. The front waist area A is the part that extends forward from the crotch area C, and side sealing structures 1 are provided on both sides of the front waist area A. The side sealing structures 1 are used to fix and separate the front waist area A and the front waist area B.

[0041] Back waist area B: Its purpose is to cover the user's lower back and hips when worn, working in conjunction with the front waist area A to form a closed waist structure. The back waist area B is the part that extends backward from the crotch area C, and side sealing structures 1 are also provided on both sides.

[0042] Crotch Area C: Its purpose is to directly cover the user's crotch area and is the main absorption area of ​​absorbent materials. Crotch Area C is composed of absorbent sheet material, extending upwards and downwards to form the front waist area A and the back waist area B.

[0043] When using, align the inner edges of the back waist area B and the front waist area A, then secure them using the side closure structure. The length, width, and material of the side closure structure can be adjusted and set according to actual needs. The design of the side closure structure allows users to easily secure the front waist area A and the back waist area B while wearing the garment, forming a closed loop waist structure to ensure a snug fit and absorbency. The open design after separating the side closure structure facilitates replacement and reduces inconvenience during wear.

[0044] In one embodiment, the fixing part 11 of the side sealing structure is intermittently or continuously detachable and fixed on both sides of the front waist area A and the back waist area B.

[0045] Specifically, the side sealing structure can be intermittently fixed on the inner edges of both sides of the front waist area A, or the side sealing structure can be continuously fixed on the inner edges of both sides of the front waist area A.

[0046] The side sealing structure can be intermittently fixed on the inner edges of both sides of the back waist area B, or it can be continuously fixed on the inner edges of both sides of the back waist area B.

[0047] In one embodiment, such as Figure 2 As shown, the adhesive portion 1 of the side sealing structure is made of a continuously pressed and adhesive material or an intermittently arranged and adhesive material. For example, the side sealing structure 1 is made of a material with adhesive portions 12.

[0048] Specifically, a side sealing structure can be continuously pressed and fixed on the inner edge of both sides (or one side) of the front waist area A, or a side sealing structure can be intermittently fixed on the inner edge of both sides (or one side) of the front waist area A.

[0049] The side sealing structure can be continuously pressed and fixed on the inner edge of both sides (or one side) of the back waist area B, or the side sealing structure can be intermittently fixed on the inner edge of both sides (or one side) of the back waist area B.

[0050] The adhesive part of the side sealing structure is made of an adhesive material, such as hook and loop fasteners, brushed fabric, or adhesive tape.

[0051] In one embodiment, such as Figure 4-8As shown, the fixing part of the side sealing structure can be fixed in an openable manner using any of the following methods: a combination of Velcro and Velcro hooks, hook engagement, or pin-type engagement. The openable fixing described in this application means that after a certain external force is applied to the fixing part, the fixing part separates, thereby separating the front waist area A and the rear waist area B.

[0052] For example, the fixing part 11 of the side sealing structure is fixed by combining Velcro and Velcro hooks, or by hooks hooking together, or by combining pins and slots.

[0053] Specifically, such as Figure 8 As shown, Velcro can be installed on the inner edge of one side of the front waist area A or the back waist area B, and Velcro hooks can be installed on the inner edge of the other side of the back waist area B or the front waist area A. The front waist area A and the back waist area B can be fixed by combining the Velcro and the Velcro hooks.

[0054] Hooks can be set on the inner edge of one side of the front waist area A or the back waist area B, and hooks can be set on the inner edge of the other side of the back waist area B or the front waist area A. The front waist area A and the back waist area B can be fixed by combining the hooks.

[0055] A pin can be installed on one inner edge of the front waist area A or the back waist area B, and a corresponding slot can be installed on the other inner edge of the back waist area B or the front waist area A. By combining the pin and the slot, the front waist area A and the back waist area B can be fixed together to form a closed absorbent item.

[0056] exist Figure 7 In the middle, when the side sealing structure is attached using Velcro, the Velcro is placed on the inner edge of one side of the front waist area A or the back waist area B, and the Velcro does not protrude beyond the inner edge of the front waist area A or the back waist area B.

[0057] Specifically, the length L of the Velcro is designed differently depending on the waist height of absorbent items (such as menstrual pants), and is generally between 80-180mm.

[0058] W1 represents the width of the hook and loop fastener before stretching, ranging from 40-150mm. W2 represents the width of the hook and loop fastener after stretching, with the stretch width determined by the elastic material's stretch ratio, typically between 1.2 and 2.0. (For example, if W1 is 80mm and the elastic stretch ratio is 1.5, then the stretch width W2 of the hook and loop fastener will be 120mm.)

[0059] In one embodiment, it was found that the Velcro-like side-sealing structure was relatively stiff and uncomfortable to wear when actually using the absorbent article described in this application. Therefore, the base fabric of the Velcro 21 can be made to be elastic in whole or in part, so that the Velcro is elastic in whole or in part, thereby increasing comfort. At the same time, in order to better grasp the Velcro and tear open the side-sealing structure, the Velcro hooks on the Velcro 21 can be set as a whole piece or in sections. The area, material, etc. of the Velcro and Velcro hooks can be set according to actual needs.

[0060] In one embodiment, such as Figure 3 As shown, the side sealing structure 1 is fixed by snap fasteners or by zippers.

[0061] Specifically, a buttonhole can be set on the inner edge of one side of the front waist area A or the back waist area B, and a snap can be set on the inner edge of the other side of the back waist area B or the front waist area A. The front waist area A and the back waist area B can be fixed by combining the snap and the buttonhole.

[0062] A fixed pin can be set on the inner edge of one side of the front waist area A or the back waist area B, and a movable pin can be set on the inner edge of the other side of the back waist area B or the front waist area A. By combining the fixed pin and the movable pin, the front waist area A and the back waist area B can be fixed.

[0063] In one embodiment, after the front waist area A and the back waist area B are fixed, if the side sealing structure does not have a corresponding opening or tear point, or if the inner edge is difficult to grip, it is not conducive to opening the side sealing structure and separating the front waist area A and the back waist area B. Alternatively, after fixing the waist area A and the back waist area B, it is inconvenient to shorten the width of the waist area A and the back waist area B. Therefore, if... Figure 9-10 As shown, the side sealing structure 1 is also provided with an openable structure 2 for opening or separating the side sealing structure 1 or adjusting the front waist area A and the back waist area B. The openable structure 2 can open the side sealing structure, thereby separating the waist area A and the back waist area B. The openable structure 2 can also shorten the width of the waist area A and the back waist area B.

[0064] Specifically, the openable structure 2 includes a connecting part 22, a joining part 23, and a tearing part 24. The connecting part is disposed on the outer edge of the waist area A and the back waist area B. The connecting part is connected to the joining part, and the joining part is connected to the tearing part. When closed, the joining part is adhered to the waist area A or the waist area B.

[0065] In one embodiment, such as Figure 9-11As shown, the closable structure 2 includes Velcro 21.

[0066] Velcro can be attached to the outer edge of either the front waist area A or the back waist area B. After the side closure is closed, the width of the waist area A and the back waist area B can be separated by the Velcro. When the absorbent item is finished being used, the side closure can be opened by tearing the Velcro, thereby separating the waist area A and the back waist area B.

[0067] In one embodiment, the absorbent article is closed when in use and open when not in use. The closed position during use facilitates covering; the open position when not in use facilitates wearing and folding.

[0068] In one embodiment, the absorbent items include menstrual pants, incontinence pants, baby pull-up pants, adult pull-up pants, and disposable underwear, which can enrich the range of uses of absorbent items.

[0069] The above is a detailed description of the preferred embodiments of this application. However, the invention of this application is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of this application. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
