Description

Technical Field

[0001] The utility model relates to the field of disposable sanitary products, and particularly relates to an openable panty-shaped absorbent article. Background Art

[0002] Panty-shaped disposable sanitary products are widely used in the field of disposable sanitary products due to their good wearing fit, especially in the field of adult disposable sanitary products. To facilitate wearing, existing panty-shaped disposable sanitary products are provided with tear lines that can be torn on the side edges, and joining members are used to tighten and fix the waist circumference. Currently, the joining members of panty-shaped disposable sanitary products are generally fixed on the side seals on both sides in the left-right direction of the front waist part, and the joining members are bonded to the front waist part through joining parts (such as Velcro). The installation direction of the joining members is from both sides towards the middle of the front waist part. For example, Chinese Patent Application No. is CN202280038960.X, and the invention patent is named Pantyliner Absorbent Article, which discloses that the pantyliner absorbent article includes: an absorbent body; a waist member including a front waist part and a rear waist part arranged at the front and rear of the absorbent body; and a joining member removably joined to the non-skin side of the front waist part, and the joining member is joined to the front waist part at both side edges in the left-right direction of the front waist part (i.e., the side seals).

[0003] The fixed installation method of the joining members of current panty-shaped disposable sanitary products has the following deficiencies. Since the material of the joining part (such as Velcro) is relatively hard, and the installation position of the joining part is prone to overlap with the folding line (the folding line in the up-down direction) of the panty-shaped disposable sanitary product, thus affecting the folding of the panty-shaped disposable sanitary product; and after folding, local bulges are likely to form on the joining members, resulting in the problem of folding wrinkles, which affects the appearance effect of the product. In addition, the joining members are installed on both side edges in the left-right direction of the front waist part (i.e., the joining members are located at the left and right waist sides), so when installing the joining members, it is necessary to twist the waist for operation, which is not convenient for the installation of the joining members; similarly, the tear lines are close to both side edges of the front waist part (i.e., the tear lines are located at the left and right waist sides), and when tearing the tear lines, it is also necessary to twist the waist for operation, which is not convenient for tearing the tear lines. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an openable panty-shaped absorbent article that can effectively avoid the folding line of the joining part of the joining member to avoid affecting folding and effectively improve the problem of folding wrinkles.

[0005] The technical solution of the utility model is as follows:

[0006] An openable panty-shaped absorbent article, comprising:

[0007] A crotch;

[0008] A waist member, including a front waist portion and a rear waist portion located in the front-back direction of the crotch;

[0009] A joining member;

[0010] The front waist portion includes an abdomen, which is located in the middle of the front waist portion. The joining member is joined to the non-skin side of the abdomen on both sides in the left-right direction, and a joining portion is provided between the joining member and the non-skin side of the front waist portion where they cooperate.

[0011] In the area where the joining member overlaps with the front waist portion, a tear area is provided, which includes a tear line extending in the up-down direction of the front waist portion. Compared with the prior art where the joining member of the panty-type absorbent article fixes the left and right side edges of the front waist portion, and the joining member is bonded to the front waist portion through the joining portion, there is a problem that the installation position of the joining portion is likely to coincide with the folding line, which affects the folding of the panty-type disposable sanitary product, and local bulges are likely to form on the joining member after folding, resulting in folding wrinkles. In contrast, for the openable panty-type absorbent article of this solution, by changing the fixing position of the joining member, the two sides of the joining member in the left-right direction are joined to the abdomen (the abdomen is located in the middle of the front waist portion). In this way, the joining portion can effectively avoid the folding line, thereby avoiding affecting the folding and effectively improving the folding wrinkle problem, and improving the folding effect.

[0012] In addition, in this embodiment, the two sides of the joining member in the left-right direction are joined to the abdomen (the abdomen is located in the middle of the front waist portion), so that the joining member is located directly in front of the waist. In this way, when installing the joining member, there is no need to twist the waist for operation, thereby improving the operation convenience of the joining member and enabling the joining member to be bonded and opened more conveniently. The joining member is located directly in front of the waist, so the corresponding tear area of the joining member is also close to the front of the waist. When tearing the tear line of the tear area, there is also no need to twist the waist for operation, which is convenient for the wearer to tear and open the front waist portion, thereby improving the operation convenience.

[0013] Preferably, the front waist portion further includes waist side extension portions located on both sides of the abdomen in the left-right direction. One end of the joining member is fixed to the abdomen, and the joining portion is provided on the surface where the joining member and / or the non-skin side of the waist side extension portion cooperate. The joining member is detachably bonded to the waist side extension portion through the joining portion. In this way, when installing the joining member, the joining member is installed from the abdomen (the middle of the front waist portion) towards the left and right side edges of the front waist portion, which is beneficial to the actual installation operation of the joining member.

[0014] Preferably, the joining portion is close to the abdomen. In this way, it can further avoid the coincidence of the joining portion and the folding line, thereby avoiding affecting the folding and effectively improving the folding wrinkle problem, and improving the folding effect.

[0015] Preferably, the tearing area is provided on the waist side extension and close to the abdomen. In this way, after the open-close underwear-type absorbent article is worn, the tearing area will be close to the front of the waist. When tearing the tearing line of the tearing area, there is no need to twist the waist for operation, which facilitates the tearing operation of the tearing line.

[0016] Preferably, the tearing area further includes a pre-tearing area, which extends from the upper edge to the lower edge of the front waist part, and the easy-tearing line is placed in the pre-tearing area in the left-right direction. In this way, the front waist part can be conveniently opened along the tearing line.

[0017] Preferably, the tearing line includes a set of discontinuous cuts. In this way, the front waist part can be conveniently opened along the tearing line.

[0018] Preferably, the joint part is strip-shaped and extends in the up-down direction of the front waist part. In this way, on the one hand, it can ensure that the joint part has a sufficient bonding area to ensure that the joint component is reliably bonded to the waist side extension through the joint part; on the other hand, it can effectively avoid the coincidence of the joint part and the folding line, avoid affecting the folding and effectively improve the folding wrinkle problem.

[0019] Preferably, the waist member includes an inner layer sheet, a middle layer sheet and an outer layer sheet which are distributed in sequence from the inside to the outside, and an elastic member is provided between the inner layer sheet and the middle layer sheet. In this way, it can not only effectively avoid the contact between the elastic member and the skin, which affects the wearing comfort; but also avoid the exposure of the elastic member.

[0020] Preferably, a fixing glue layer is provided between the middle layer sheet and the outer layer sheet. In this way, the integrity of the waist member can be effectively improved.

[0021] Preferably, a reinforcing glue layer is also provided between the inner layer sheet and the middle layer sheet corresponding to the area where the joint component overlaps with the front waist part. In this way, during the installation and disassembly of the joint component, the area on the outer layer sheet corresponding to the overlap of the joint component and the front waist part is not easily pulled up and torn.

[0022] The beneficial effects of the present utility model are:

[0023] The two sides of the joint component in the left-right direction are combined on the abdomen (the abdomen is located in the middle of the front waist part). In this way, the joint part can effectively avoid the folding line, thereby avoiding affecting the folding and effectively improving the folding wrinkle problem and improving the folding effect.

[0024] The two sides of the joining member in the left - right direction are joined to the abdomen (the abdomen is located in the middle of the front waist part), that is, the joining member is located directly in front of the waist. In this way, when installing the joining member, there is no need to twist the waist for operation, which facilitates the installation of the joining member. Since the joining member is located directly in front of the waist, the tear area corresponding to the joining member is also close to the front of the waist. When tearing the tear line of the tear area, there is also no need to twist the waist for operation, which facilitates the tearing operation of the tear line. Brief Description of the Drawings

[0038] The separable underwear-type absorbent article of this embodiment can be a disposable underwear having an absorbent core (the specific installation method and structure of the absorbent core are prior art, and this structure is not the inventive point of this application, so this application does not elaborate on the specific installation method and structure of the absorbent core and other conventional technical means); it can also be a disposable underwear without an absorbent core.

[0039] In the prior art, the joining member 3 of the panty-shaped absorbent article is fixed to the left and right side edges in the lateral direction of the front waist portion 2.1. The joining member 3 is bonded to the front waist portion 2.1 through the joint portion 3.1. There is a problem that the installation position of the joint portion 3.1 is likely to coincide with the folding line, which affects the folding of the panty-shaped disposable sanitary product, and local bulges are likely to form on the joining member 3 after folding, resulting in folding wrinkles. In contrast, in the openable panty-shaped absorbent article of this embodiment, by changing the fixing position of the joining member 3, the two sides of the joining member 3 in the lateral direction are joined to the abdomen 2.1.1 (the abdomen 2.1.1 is located in the middle of the front waist portion 2.1). In this way, the joint portion 3.1 can effectively avoid the folding line, thereby avoiding affecting the folding and effectively improving the folding wrinkle problem and enhancing the folding effect.

[0040] In addition, in this embodiment, the two sides of the joining member 3 in the lateral direction are joined to the abdomen 2.1.1 (the abdomen 2.1.1 is located in the middle of the front waist portion 2.1), so that the joining member 3 is located directly in front of the waist. In this way, when installing the joining member 3, there is no need to twist the waist for operation, thereby improving the operational convenience of the joining member 3 and enabling the joining member 3 to be bonded and opened more conveniently. Since the joining member 3 is located directly in front of the waist, the tearing area 4 corresponding to the joining member 3 is also close to the front of the waist. When tearing the tearing line 4.1 of the tearing area 4, there is also no need to twist the waist for operation, which is convenient for the wearer to tear and open the front waist portion 2.1, thereby improving the operational convenience.

[0041] Specifically, the front waist portion 2.1 further includes waist side extension portions 2.1.2 located on the left and right sides of the abdomen 2.1.1. The joining member 3 is in a sheet shape, such as a snap fixing piece. One end of the joining member 3 is fixed to the abdomen 2.1.1, and the other side of the joining member 3 is a free end. The joint portion 3.1 is provided on the surface of the joining member 3 and / or the non-skin side surface of the waist side extension portion 2.1.2 that are in cooperation. The joining member 3 is detachably bonded to the waist side extension portion 2.1.2 through the joint portion 3.1. In this way, when installing the joining member 3, the joining member 3 is installed from the abdomen 2.1.1 (the middle of the front waist portion 2.1) towards the left and right side edges of the front waist portion 2.1, which is beneficial to the actual installation operation of the joining member 3.

[0042] In one implementation manner of this embodiment, the joint portion 3.1 is provided on the surface of the joining member 3 that is in cooperation with the non-skin side surface of the front waist portion 2.1. The joint portion 3.1 can be bonded to the non-skin side surface of the front waist portion 2.1, and the joining member 3 can be opened and separated from the front waist portion 2.1 under an external force. The surface of the joint portion 3.1 is distributed with barbs that hook the front waist portion 2.1, such as the male patch of Velcro with relatively hard barbed bristles.

[0043] In another implementation of this embodiment, the engaging portion 3.1 includes a male and a female engaging portion 3.1. One of them is disposed on one surface of the engaging member 3 that cooperates with the front waist portion 2.1, and the other is disposed on the non-skin side surface of the front waist portion 2.1. The male and female engaging portions 3.1 can be opened under an external force, so that the engaging member 3 can be opened under an external force. The surface of the male engaging portion 3.1 of the male and female engaging portions 3.1 is distributed with barbs, and the surface of the female engaging portion 3.1 is distributed with fine and soft fibers, such as the male and female patches in Velcro.

[0044] In the third implementation of this embodiment, the engaging portion 3.1 is disposed on the non-skin side surface of the front waist portion 2.1 that cooperates with the engaging member 3.

[0051] Furthermore, the waist member 2 includes an inner layer sheet 2.3, a middle layer sheet 2.4, and an outer layer sheet 2.5 which are distributed in sequence from the inside to the outside. Specifically, the front waist part 2.1 includes an inner layer sheet 2.3, a middle layer sheet 2.4, and an outer layer sheet 2.5 which are distributed in sequence from the inside to the outside, and the rear waist part 2.2 includes an inner layer sheet 2.3, a middle layer sheet 2.4, and an outer layer sheet 2.5 which are distributed in sequence from the inside to the outside. The outer layer sheet 2.5 is made of materials such as spunbond non-woven fabric, hot-rolled non-woven fabric, spunmelt non-woven fabric, and hot air non-woven fabric; the inner layer sheet 2.3 is made of materials such as spunbond non-woven fabric, hot-rolled non-woven fabric, and spunmelt non-woven fabric.

[0052] An elastic member 2.6 is provided between the inner layer sheet 2.3 and the middle layer sheet 2.4. In this way, not only can the contact between the elastic member 2.6 and the skin be effectively avoided, which affects the wearing comfort, but also the exposure of the elastic member 2.6 can be avoided. The elastic member 2.6 includes a front waist elastic member 2.6 and a rear waist elastic member 2.6. The front waist elastic member 2.6 is arranged between the inner layer sheet 2.3 and the middle layer sheet 2.4 of the front waist part 2.1 and extends along the left-right direction of the front waist part 2.1. The rear waist elastic member 2.6 is arranged between the inner layer sheet 2.3 and the middle layer sheet 2.4 of the rear waist part 2.2 and extends along the left-right direction of the rear waist part 2.2.

[0053] To solve the problem that the front waist elastic member 2.6 is not cut off at the tearing area 4, resulting in an increased force required for tearing and affecting the user's experience; in this embodiment, the front waist elastic member 2.6 in the pre-tearing area is point-cut, so that the front waist part 2.1 can be opened along the tearing line 4.1 when tearing. In addition, according to the actual situation, a plurality of binding points can be provided on the front waist part 2.1 to bind and fix the front waist elastic member 2.6 with the outer layer sheet 2.5 and the inner layer sheet 2.3 of the front waist part 2.1.

[0054] Furthermore, a fixing adhesive layer 2.7 is provided between the middle layer sheet 2.4 and the outer layer sheet 2.5, and the fixing adhesive layer 2.7 bonds the middle layer sheet 2.4 and the outer layer sheet 2.5 into one body. In this way, the integrity of the waist member 2 can be effectively improved.

[0055] A reinforcing adhesive layer 2.8 is further provided in the area where the inner layer sheet 2.3 and the middle layer sheet 2.4 correspond to the overlapping area of the joint member 3 and the front waist portion 2.1. In this way, during the installation and disassembly of the joint member 3, the area on the outer layer sheet 2.5 corresponding to the overlapping area of the joint member 3 and the front waist portion 2.1 is not easily pulled up and torn.
