Technical Field
[0001] This utility model relates to the field of openable women's sanitary pants technology, and in particular to an openable elastic laminate. Background Technology
[0002] To improve the comfort of women's sanitary panties, an elastic laminate can be used in the waistband. In the prior art, invention patent application number 2019800127785 discloses a wearable article that includes an elastic laminate.
[0003] During menstruation, women need to change their sanitary panties frequently. To improve ease of changing, the waistband can be designed with an elasticated, clasp-style construction. Additionally, Velcro closures allow for convenient opening and closing. Velcro can be attached to the inside or outside of the elasticated design, but each has its drawbacks.
[0004] When the Velcro is installed on the inner side of the elastic composite close to the human body, it causes local contact between the Velcro and the human skin, which can easily cause discomfort to the human body.
[0005] When the Velcro is installed on the outside of the elastic layer, away from the body, it comes into contact with the clothing and is prone to separation at the joint between the Velcro and the elastic layer due to friction, which can cause the sanitary pants to come loose unexpectedly. This needs to be improved. Utility Model Content
[0006] The purpose of this invention is to provide an openable elastic laminate that improves ease of operation and avoids discomfort and accidental loosening.
[0007] To achieve this objective, the present invention adopts the following technical solution:

The second elastic laminate includes a second elastic portion, a second skin-friendly layer, and a second abrasion-resistant layer. The second skin-friendly layer is disposed behind the second abrasion-resistant layer, and the second elastic portion is disposed between the second skin-friendly layer and the second abrasion-resistant layer. A plurality of first connecting portions are spaced apart along the length direction between the first skin-friendly layer and the first abrasion-resistant layer, and a plurality of second connecting portions are spaced apart along the length direction between the second skin-friendly layer and the second abrasion-resistant layer. Both ends of the first skin-friendly layer and the first abrasion-resistant layer are respectively provided with outwardly extending clasp connecting portions. A hook and loop fastener is provided on the side of the clasp connecting portion adjacent to the second elastic laminate, and a hook and loop fastener corresponding to the hook and loop fastener is provided on the side of the second abrasion-resistant layer opposite to the first elastic laminate.
[0009] Wherein, the first elastic part passes through the first joint, and in its natural state, the first skin-friendly layer and the first wear-resistant layer respectively have a continuous wave-shaped bending structure.
[0010] The second elastic part passes through the second joint, and in its natural state, the second skin-friendly layer and the second wear-resistant layer respectively have a continuous wave-shaped bending structure.
[0011] The first and second skin-friendly layers are made of pure cotton non-woven fabric.
[0012] The first and second wear-resistant layers are made of polyester nonwoven fabric.
[0013] The first elastic part includes several elastic rubber bands or elastic yarns, and the second elastic part includes several elastic rubber bands or elastic yarns.
[0014] The beneficial effects of this utility model are as follows: The opening and closing elastic laminate has the opening and closing connection part and the first elastic laminate being located at both ends between the first skin-friendly layer and the first wear-resistant layer. That is, it is sandwiched between the first skin-friendly layer and the first wear-resistant layer, so it does not come into contact with the human body, avoiding discomfort, and is not affected by the friction of clothing, avoiding accidental loosening.

[0015] Figure 1 This is a schematic diagram (top view) of the structure of this utility model;
[0016] Figure 2 yes Figure 1 Front view of the second elastic laminate;
[0017] Figure 3 This is a schematic diagram of the connection structure between the first elastic laminate and the second elastic laminate in this utility model. Detailed Implementation
[0018] The following is combined with Figures 1-3 The technical solution of this utility model will be further illustrated through specific embodiments.
[0019] like Figure 1 The openable elastic laminate shown includes: a first elastic laminate 1 and a second elastic laminate 2. The second elastic laminate 2 is located in front of the first elastic laminate 1. The first elastic laminate 1 includes a first elastic part 13, a first skin-friendly layer 12 and a first wear-resistant layer 11. The first skin-friendly layer 12 is disposed in front of the first wear-resistant layer 11, so that the first skin-friendly layer 12 can contact the skin of the waist of the human body, which provides good comfort.
[0020] A plurality of first bonding portions 14 are provided at intervals along the length direction between the first skin-friendly layer 12 and the first wear-resistant layer 11. The first bonding portions 14 are obtained by hot pressing, adhesive or ultrasonic welding to ensure the connection stability between the first skin-friendly layer 12 and the first wear-resistant layer 11.
[0021] The first elastic portion 13 is disposed between the first skin-friendly layer 12 and the first wear-resistant layer 11. In this embodiment, the first elastic portion 13 passes through the first joint portion 14, and the first elastic portion 13 is segmented and fixed through the first joint portion 14. Figure 1 As shown, in the natural state (without stretching), the first skin-friendly layer 12 and the first wear-resistant layer 11 have continuous wave-shaped bending structures. When the first elastic part 13 is elastically stretched, the first skin-friendly layer 12 and the first wear-resistant layer 11 reduce bending or are straightened.
[0022] Similarly, the second elastic composite 2 includes a second elastic part 23, a second skin-friendly layer 22, and a second abrasion-resistant layer 21. The second skin-friendly layer 22 is disposed on the back side of the second abrasion-resistant layer 21. After being made into an open-front women's sanitary panty, it comes into contact with the skin of the waist through the second skin-friendly layer 22. In this embodiment, the first skin-friendly layer 12 and the second skin-friendly layer 22 are respectively made of pure cotton non-woven fabric, which is soft and comfortable and will not cause skin allergies.
[0023] In addition, the first wear-resistant layer 11 and the second wear-resistant layer 21 are made of polyester non-woven fabric, which has a strong structure and good wear resistance, avoiding wear or breakage during the wearing process.
[0024] Several second bonding portions 24 are provided at intervals along the length direction between the second skin-friendly layer 22 and the second wear-resistant layer 21. The second bonding portions 24 are obtained by hot pressing, adhesive or ultrasonic welding to fix the second skin-friendly layer 22 and the second wear-resistant layer 21 in sections, so as to ensure the connection stability of the second skin-friendly layer 22 and the second wear-resistant layer 21.
[0025] The second elastic portion 23 is disposed between the second skin-friendly layer 22 and the second wear-resistant layer 21, such as Figure 1 As shown, the second elastic part 23 passes through the second joint 24. In its natural state, the second skin-friendly layer 22 and the second wear-resistant layer 21 have continuous wave-shaped bending structures, ensuring that they can change with the expansion and contraction of the second elastic part 23, resulting in rich overall elasticity.
[0026] like Figure 2 As shown, the first elastic part 13 includes several elastic rubber bands or elastic yarns, and the second elastic part 23 includes several elastic rubber bands or elastic yarns, such as several elastic yarns that are spaced vertically apart, so that the elasticity distribution is more uniform.
[0027] like Figure 1 As shown, outwardly extending opening and closing connecting parts 15 are respectively provided at both ends between the first skin-friendly layer 12 and the first wear-resistant layer 11. The opening and closing connecting parts 15 are clamped by the first skin-friendly layer 12 and the first wear-resistant layer 11 and fixed by means of hot pressing, adhesive or ultrasonic welding, which can not only ensure the structural firmness, but also avoid the contact between the opening and closing connecting parts 15 and the first skin-friendly layer 12 or the first wear-resistant layer 11 and the human body, thus avoiding discomfort to the human body. The connection is not affected by the friction of clothing, thus avoiding the problem of accidental loosening, making it safer and more comfortable to use.
[0028] In this embodiment, the opening and closing connection portion 15 is provided with a hook and loop fastener surface 16 on the side adjacent to the second elastic composite 2, and the second wear-resistant layer 21 is provided with a hook and loop fastener surface 25 corresponding to the hook and loop fastener surface on the side opposite to the first elastic composite 1. Figure 3 As shown, after the opening and closing connecting part 15 bends and flips forward, the first elastic layer assembly 1 and the second elastic layer assembly 2 are quickly connected by the cooperation of the hook and loop fastener 16 and the rough surface 25, making disassembly convenient. The rough surface 25 can be obtained by roughening the end surface of the second wear-resistant layer 21, which is low in cost.
[0029] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
