Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of disposable sanitary products, in particular to baby pants, adult pants and feminine hygiene pants, and more particularly to a pant-type wearing article. BACKGROUND

[0002] A pant-type wearing article (e.g. an openable pant product) generally comprises an elastic outer cover, an absorbent main body arranged inside the outer cover, and fastening members (or fastening belts) arranged on both sides of the outer cover. The fastening members are generally composed of a base sheet and hook elements. The outer cover has a front waist portion corresponding to the abdominal side of the wearer, a back waist portion corresponding to the back side of the wearer, and a crotch portion arranged between the front waist portion and the back waist portion. The front waist portion of the outer cover is provided with a separation portion (e.g. formed by a tearable line) on each side. For the openable pant-type wearing article in the prior art, the fastening members are arranged on the same side of the front waist portion as the separation portion, and the fastening members can be repeatedly attached to or removed from the front waist portion of the outer cover. Before wearing, the fastening members are attached to the front waist portion of the outer cover; during wearing, the fastening members are removed from the front waist portion of the outer cover, the separation portion is separated, and the fastening members are then attached to the front waist portion of the outer cover.

[0003] In addition, the openable pant-type wearing article in the prior art has the side edges of the front waist portion and the back waist portion sealed to form side seal portions, so that the product has a pant shape with one waist opening and two leg openings. The side seal portions are generally formed by any one or a combination of heat pressing, ultrasonic bonding or hot melt adhesive, so that the side seal portion area is relatively hard compared to other areas of the wearing article, which may cause the wearer to feel uncomfortable during wearing. In addition, the side seal portions are exposed, which not only affects the appearance of the wearing article, but also cannot achieve the desired no-trace effect on both sides.

[0004] In addition, there is another openable pant-type wearing article on the market, in which the fastening members are temporarily fixed to the back waist portion in a folded state by hot melt adhesive (also known as hot melt glue), and the separation portion is arranged on the front waist portion. In the wearing state, the separation portion is separated (i.e. the tearable line is torn), the fastening members are attached to the front waist portion of the wearer in an extended state, and the hot melt adhesive used for temporary fixation will remain on the fastening members. The remaining hot melt adhesive is easy to adhere to the wearer's clothes or skin, and the use of hot melt adhesive increases the production cost and also has an impact on the environment.

[0034] As Figure 1 , Figure 2 and Figure 9As shown, shorts-type clothing items have length, width, and thickness directions that are orthogonal to each other. The length direction is the direction of the shorts-type clothing item when it is unfolded, and the width direction is orthogonal to the length direction (e.g.,...). Figure 1 (As shown), the thickness direction is orthogonal to both the length and thickness directions. The length direction includes the front and back sides; the front side refers to the front of the wearer when wearing shorts-style clothing, and the back side refers to the back of the wearer. The thickness direction includes the skin side and non-skin side, such as... Figure 2 As shown, the skin side is the side that comes into contact with the wearer's skin when wearing shorts-type clothing. Figure 2 The upper side (as shown), the non-skin side is the opposite side ( Figure 2 (As shown on the lower side). Figure 1 As shown, the shorts-type garment has a front waistband B1 located along the length of the wearer's abdomen, a back panel B2 located along the back of the wearer, and a crotch area B3 located between the front waistband B1 and the back panel B2. Along the length of the garment, the shorts-type garment has a front body portion Fr and a back body portion Be positioned opposite each other. The front body portion Fr corresponds to the front of the wearer's body, and the back body portion Be corresponds to the back of the wearer's body. The two sides of the front waistband B1 and the two sides of the back panel B2 along the width direction are sealed to form side closures 41, resulting in a pant-like shape with one waist opening and two leg openings. Figure 5 As shown.

[0040] In still another embodiment of the present application, in the unworn state, the separation portion 24 is not separated, and the first elastic member 23 is completely cut off or at least a part of the first elastic member 23 is involved and in the elongated state with tension at both side regions of the separation portion 24 in the width direction.

[0041] In some embodiments of the present application (i.e., the embodiment in which the outer cover 20 includes the inner sheet 21, the outer sheet 22, and the first elastic member 23, and the embodiment in which the outer cover 20 includes only the inner sheet 21 and the outer sheet 22), at the front waist portion B1 or the back waist portion B2, a reinforcing fixed region P is further provided at both sides of the separation portion 24 in the width direction, as shown in Figure 8 At the reinforcing fixed region P, the inner sheet 21, the first elastic member 23, and the outer sheet 22 are reinforced and fixed by at least one of a hot melt adhesive process, a heat press process, and an ultrasonic process, to prevent the first elastic member 23 from retracting in the width direction at both sides of the separation portion 24.

[0042] As shown in Figure 1 and Figure 2 , the short pants-type wearing article further includes a pair of fastening members 30. The fastening member 30 includes a base sheet 31, a hook element 32, a fastening member joint portion 33, and a provisional portion 34. In the present embodiment, the base sheet 31 is a nonwoven fabric like the inner sheet 21 (the outer sheet 22), but has different fibers. The base sheet 31 has a size in the length direction that is smaller than the size of the side seal portion 41, specifically, a size in the length direction that is 95% or less of the size of the side seal portion 41. At least a part of the outer side edge of the base sheet 31 has an arc shape in the length direction. The base sheet 31 is disposed on the non-skin side of the front waist portion B1 or the back waist portion B2 by the fastening member joint portion 33. Specifically, as in the embodiment shown in Figure 3 and Figure 4 , the outer side edge of the base sheet 31 is disposed on the non-skin side of the outer sheet 22 of the back waist portion B2 by the fastening member joint portion 33. The fastening member joint portion 33 has an overlapping portion with the side seal portion 41 in the thickness direction.

[0043] Further, in the present embodiment, the fastening member engaging portion 33 and the side seal portion 41 can be formed in one process, i.e., the fastening member engaging portion 33 and the side seal portion 41 are formed together by the same process. Specifically, in the front waist portion B1 and the back waist portion B2, the two side edges of the inner sheet 21 and the outer sheet 22 in the width direction are respectively sealed together with the end portions of the pair of base sheet 31 by at least one of a heat press process or an ultrasonic process. In other embodiments, the fastening member engaging portion 33 and the side seal portion 41 can also be formed in two processes, i.e., the fastening member engaging portion 33 and the side seal portion 41 are formed in sequence by the same or different processes. Specifically, in the front waist portion B1 and the back waist portion B2, the two side edges of the inner sheet 21 and the outer sheet 22 in the width direction are sealed to form the side seal portion 41 by at least one of a heat press process or an ultrasonic process, and then the end portions of the base sheet 31 are fixedly connected thereto to form the fastening member engaging portion 33.

[0044] Referring back to Figure 1 and Figure 2 , the fastening member 30 is configured to have a bent portion 31a. When the bent portion 31a is located at the back waist portion B2, the separation portion 24 is located at the front waist portion B1. When the bent portion 31a is located at the front waist portion B1, the separation portion 24 is located at the back waist portion B2. That is, when the bent portion 31a is located at the front waist portion B1 or the back waist portion B2, the separation portion 24 is correspondingly located at the back waist portion B2 or the front waist portion B1. In the worn state, in the width direction, the separation portion 24 is disposed in the region between the side seal portion 41 and the hook element 32 (see the description below), and the separation portion 24 is closer to the side seal portion 41 than the hook element 32.

[0045] In the embodiments of the present application, the end of the base sheet 31 away from the fastening member engaging portion 33 is provided with a hook element 32. When the bent portion 31a is formed, the hook element 32 is provided on the inner side of the bent portion 31a. The two ends of the hook element 32 in the length direction respectively extend to the outer side edge of the base sheet 31, and are the same length as the base sheet 31 in the length direction. The hook element 32 is in the shape of a strip or a trapezoid. The hook element 32 is fixed to the base sheet 31 by at least one of a heat press process or an ultrasonic process. Further, at least one of the hook element 32 and the base sheet 31 is coated with hot melt adhesive and adhered to each other. The grammage of the hook element 32 is within 2 times the grammage of the base sheet 31, so that the matching between the hook element 32 and the base sheet 31 is better, the adhesion is easier, and the adhesion is more firm. The hook element 32 is used to temporarily fixedly connect to the non-skin side of the back waist portion B2 or the front waist portion B1. Specifically, a plurality of small protrusions (not labeled in the figure) are provided on the hook element 32, which are used for repeated attachment or removal with the non-skin side of the back waist portion B2 or the front waist portion B1. In this case, the non-woven fabric used for the outer sheet 22 can be entangled with the small protrusions to facilitate the attachment or removal with the hook element 32, thereby facilitating the putting on and taking off of the short pants type wearing article.

[0046] In the embodiment shown in FIG. 1, the fastening member 30 is temporarily fixed to the non-skin side of the back portion B2 in a relaxed state by means of the hook elements 32. In the embodiment shown in FIG. 2, the fastening member 30 is temporarily fixed to the non-skin side of the front waist portion B1 in a relaxed state by means of the hook elements 32. Figure 6 Figure 7 In the embodiment shown in FIG. 1, the fastening member 30 is temporarily fixed to the non-skin side of the back portion B2 in a relaxed state by means of the hook elements 32. In the embodiment shown in FIG. 2, the fastening member 30 is temporarily fixed to the non-skin side of the front waist portion B1 in a relaxed state by means of the hook elements 32.

[0047] As shown in FIG. 1, the fastening member 30 further comprises a temporary fixing portion 34. The temporary fixing portion 34 is used to temporarily fix the folded base material sheet 31 by at least one of the following ways: heat pressing and ultrasonic wave, so as to maintain the folded state (shape) of the fastening member 30 and prevent the fastening member 30 from being scattered before packaging or use. When wearing the short pants type wearing article, the hook elements 32 are removed from the non-skin side of the back portion B2 or the front waist portion B1, and then the temporary fixing portion 34 is unfolded, so that the fastening member 30 changes from the folded state to the stretched state, thereby facilitating wearing. Figure 1 As shown in FIG. 1, the fastening member 30 further comprises a temporary fixing portion 34. The temporary fixing portion 34 is used to temporarily fix the folded base material sheet 31 by at least one of the following ways: heat pressing and ultrasonic wave, so as to maintain the folded state (shape) of the fastening member 30 and prevent the fastening member 30 from being scattered before packaging or use. When wearing the short pants type wearing article, the hook elements 32 are removed from the non-skin side of the back portion B2 or the front waist portion B1, and then the temporary fixing portion 34 is unfolded, so that the fastening member 30 changes from the folded state to the stretched state, thereby facilitating wearing.

[0048] Figure 4 ​​In the illustrated embodiment (where the bent portion 31a is located at the back portion B2 and the separation portion 24 is located at the front waist portion B1), in the worn state, the hook member 32 is removed from the back portion B2, such that the bent portion 31a of the fastening member 30 is released from the non-skin side of the back portion B2, and the separation portion 24 is separated, in which case, the base sheet 31 in the stretched state is attached from the back portion B2 to the front waist portion B1, such that the hook member 32 is removably attached to the non-skin side of the front waist portion B1 in the stretched state, such that the base sheet 31 wraps the side seal portion 41 and the fastening member engaging portion 33, thereby hiding the side seal portion 41 and the fastening member engaging portion 33 inside the base sheet 31, and further such that the short pants-type wearing article exhibits a traceless effect at both widthwise side edges, and does not rub against the wearer's skin, thereby providing a good tactile sensation to the wearer, and improving the overall wearing effect, as Figure 9 Of course, in other embodiments (where the bent portion 31a is located at the front waist portion B1 and the separation portion 24 is located at the back portion B2), in the worn state, the hook member 32 is removed from the front waist portion B1, such that the bent portion 31a of the fastening member 30 is released from the non-skin side of the front waist portion B1, and the separation portion 24 is separated, in which case, the base sheet 31 in the stretched state is attached from the front waist portion B1 to the back portion B2, such that the hook member 32 is removably attached to the non-skin side of the back portion B2 in the stretched state, such that the base sheet 31 wraps the side seal portion 41 and the fastening member engaging portion 33, thereby hiding the side seal portion 41 and the fastening member engaging portion 33 inside the base sheet 31, and further such that the short pants-type wearing article exhibits a traceless effect at both widthwise side edges.

[0049] Further, as Figure 3In the illustrated embodiment (where the bent portion 31a is located at the back portion B2 and the separation portion 24 is located at the front waist portion B1), before wearing, the base material sheet 31 is temporarily fixed to the back portion B2 in a folded manner so that the base material sheet 31 can be configured to a predetermined size in the width direction, and after the separation portion is separated, the hook element 32 is attached to the non-skin side of the front waist portion B1, and the base material sheet 31 connects the front waist portion B1 and the back portion B2. In this way, by adjusting the attachment position of the hook element 32 to the non-skin side of the front waist portion B1, the waist opening size of the short pants type wearing article can be flexibly adjusted according to the wearing user's usage requirements. Of course, in other embodiments (where the bent portion 31a is located at the front waist portion B1 and the separation portion 24 is located at the back portion B2), before wearing, the base material sheet 31 is temporarily fixed to the front waist portion B1 in a folded manner so that the base material sheet 31 can be configured to a predetermined size in the width direction, and after the separation portion is separated, the hook element 32 is attached to the non-skin side of the back portion B2, and the base material sheet 31 connects the front waist portion B1 and the back portion B2. In this way, by adjusting the attachment position of the hook element 32 to the non-skin side of the back portion B2, the waist opening size of the short pants type wearing article can be flexibly adjusted according to the wearing user's usage requirements.

[0050] Continuing to refer to Figure 1 As shown, the outer body 20 located at the crotch portion B3 is also configured with a second elastic member 25. The second elastic member 25 is made of spandex silk, and of course can also be made of natural rubber strips (silk) or other elastic materials. The second elastic member 25 extends along an arc curve from the front waist portion B1 to the crotch portion B3, and also extends along an arc curve from the back portion B2 to the crotch portion B3. As shown, Figure 1 As shown, the arc curve of the second elastic member 25 matches the leg opening edge of the short pants type wearing article, so that the extension shape of the second elastic member 25 matches the leg circumference line 26 of the arc-shaped leg edge of the human body, and more closely fits the leg contour of the wearer. It should be noted that in the area where the outer body 20 overlaps with the absorbent main body 10, the elasticity of the outer body 20 is destroyed or weakened, forming an elastic weakening area (not shown in the figure), thereby improving the flatness of the composite of the absorbent main body 10 and the outer body 20.
