[0023] The following description is merely exemplary in nature and is not intended to limit the present invention, its application and use. It should be understood that in all of the accompanying drawings, similar reference numerals indicate the same or similar components and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present invention, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present invention. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present invention.
[0024] Figure 1 and Figure 2 1 shows a cross-sectional view of the hook component 1 according to the first embodiment of the present invention, showing the hook component 1 in a folded state and an unfolded state, respectively. Figure 1 and Figure 2 As shown, the hook component 1 includes a carrier 10, a fastener 20 and a flexible attachment 30. The carrier 10 can be made of non-woven fabric and has a surface 11 ( Figure 1 The carrier 10 is provided with a first adhesive layer 12 (in the figure, the upper surface). The first adhesive layer 12 is preferably a pressure-sensitive adhesive layer. The surface 11 of the carrier 10 is provided with a finger lift area. Specifically, in the example shown in the figure, the hook component 1 includes a handle film 13 provided on the carrier 10. The handle film 13 is bonded to the carrier 10 via the first adhesive layer 12, and the handle film 13 forms the finger lift area of the carrier 10.
[0025] The fastener 20 constitutes the folding pivoting part of the hook component 1. The fastener 20 includes a body portion 21. A plurality of hook-shaped members 22 are arranged on the first surface of the body portion 21. The plurality of hook-shaped members 22 can be arranged in a predetermined pattern on the first surface of the body portion 21 as required. The hook-shaped member 22 protrudes from the first surface of the body portion 21, and its free end is suitable for connecting with the loop-shaped member hook loop of the corresponding loop component. In the example shown in the figure, the hook-shaped member 22 is T-shaped. However, the utility model is not limited thereto. In other examples according to the utility model, the hook-shaped member 22 can be in any other suitable shape, such as a curved hook shape, a mushroom head shape, etc. The first surface of the body portion 21 (the surface provided with the hook-shaped member 22) is suitable for facing the finger-lifting area of the carrier 10. A second adhesive layer 23 is arranged on the second surface of the body portion 21 opposite to the first surface. The second adhesive layer 23 is preferably a pressure-sensitive adhesive layer. For example, the second adhesive layer 23 can be made of the same pressure-sensitive adhesive as the first adhesive layer 12. The second adhesive layer 23 is bonded to a flexible attachment member 30 to be described below, and is suitable for bonding to a surface of a terminal product (hook and loop coupling product).
[0026] The flexible attachment 30 is connected between the fastener 20 and the carrier 10. The flexible attachment 30 is, for example, a flexible film, which may be a non-adhesive flexible film. One side surface 34 of the flexible attachment 30 is bonded to the first adhesive layer 12 on the carrier 10. And, as described above, a portion of the second adhesive layer 23 on the fastener 20 is bonded to the flexible attachment 30, and another portion of the second adhesive layer 23 is suitable for bonding to the surface of the terminal product.
[0027] In the example shown in the figure, the second adhesive layer 23 on the fastener 20 is bonded to the other side surface 35 of the flexible attachment 30. That is, the first adhesive layer 12 and the second adhesive layer 23 are respectively bonded to the opposite side surfaces of the flexible attachment 30. Figure 1 In the folded state shown, one side surface 35 of the first end portion 31 of the flexible attachment 30 is adhered to a portion of the second adhesive layer 23, and the other side surface 34 of the second end portion 32 of the flexible attachment 30 is adhered to a portion of the first adhesive layer 12. In the folded state, the flexible attachment 30 is folded into a generally C-shape, so that the first surface of the body portion 21 of the fastener 20 (i.e., the surface provided with the hook-shaped member 22) faces the carrier 10 and the finger-lift area. Specifically, at least a portion of the first surface of the body portion 21 of the fastener 20 faces the flexible attachment 30 on the carrier 10, and another portion of the first surface of the body portion 21 of the fastener 20 faces the finger-lift area on the carrier 10. Figure 1As shown, in the folded state, a portion of the first surface of the body portion 21 of the fastener 20 faces the surface 35 of the second end portion 32 of the flexible attachment 30 , and another portion of the first surface of the body portion 21 of the fastener 20 faces the handle film 13 .
[0028] When the hook component 1 is mounted to the mounting portion 40 of the terminal product, the fastener 20 is pivoted and unfolded, for example, along the Figure 1 The flexible attachment 30 is pivoted and unfolded in the direction indicated by the arrow A in the figure, so that the second adhesive layer 23 on the fastener 20 faces the carrier 10, more specifically, faces the first adhesive layer 12 on the carrier 10, the flexible attachment 30 is flattened to the first adhesive layer 12 on the carrier 10, the entire surface 34 of the flexible attachment 30 is adhered to the first adhesive layer 12 on the carrier 10, and the mounting portion 40 of the terminal product can be sandwiched between the first adhesive layer 12 and the second adhesive layer 23 and adhered to the first adhesive layer 12 and the second adhesive layer 23, as shown in FIG. Figure 2 shown.
[0029] In the example shown in the figure, the handle film 13 is bonded to the carrier 10 via the first adhesive layer 12 and is located on the side where the second end 32 of the flexible attachment 30 is located. The handle film 13 forms a finger lift area of the carrier 10. The handle film 13 is spaced apart from the second end 32 of the flexible attachment 30, so that in the folded state, at least a portion of the hook-shaped member 22 of the fastener 20 faces the first adhesive layer 12 on the carrier 10 and can contact the first adhesive layer 12. Therefore, through the contact between the hook-shaped member 22 and the first adhesive layer 12, the hook component 1 can be stably maintained in the folded state without springing open and causing a flash problem.
[0030] The hook member 1 can be Figure 1 The folded state shown forms a hook component web and is wound into a roll. When in use, the hook component web can be cut into hook components 1 as shown with a predetermined length as needed.
[0031] In addition, alternatively, the hook components 1 may be arranged in a side-by-side manner to form a hook component web. Figure 3 As shown, fasteners 20 are respectively provided on both sides of the handle film 13, so that the hook components 1 can be arranged side by side in the width direction to form a hook component web. When cut along the cutting line S, two separate hook-shaped components 1 can be obtained. Optionally, when the hook components 1 are arranged side by side, weak parts can be provided at positions corresponding to the cutting line S on the handle film 13 and the carrier 12 to facilitate separation of the hook components 1 arranged side by side.
[0032] Figure 4 and Figure 5A cross-sectional view of a hook component 1A according to a comparative example is shown, showing a folded state and an unfolded state of the hook component 1A, respectively. In the drawings, the same parts as the hook component 1 according to the present invention are denoted by the same reference numerals, and the description thereof will not be repeated. In the following, only the difference between the hook component 1A according to the comparative example and the hook component 1 according to the present invention will be described.
[0033] like Figure 4 and Figure 5 As shown, the hook component 1A includes a carrier 10, a fastener 20A and a flexible attachment 30, and further includes an adhesive 50. In the hook component 1A, the adhesive portion 50 is a folded pivot portion of the hook component 1A. The adhesive 50 includes a release tape 51 and an adhesive layer 52 provided on the release tape 51. The body portion 21 of the fastener 20A is bonded to the carrier 10 via the first adhesive layer 12 on the carrier 10, and the fastener 20A is located between the adhesive 50 and the handle film 13. This configuration allows the overall length of the hook component 1A to be longer.
[0034] The first end 31 of the flexible attachment 30 is bonded to the adhesive layer 52 of the adhesive 50 , and the second end 32 of the flexible attachment 30 is bonded to the first adhesive layer 12 on the carrier 10 .
[0035] exist Figure 4 In the folded state shown, the release tape 51 faces the carrier 10 or partially faces the hook 22 of the fastener 20A. In the case where the release tape 51 does not face the hook 22 of the fastener 20A, a non-adhesive film 14 is usually also provided between the flexible attachment 30 and the fastener 20A, so that in the folded state, a portion of the release tape 51 faces the non-adhesive film 14. The release tape 51 itself is not adhesive and has a non-adhesive smooth surface, for example, a non-adhesive smooth surface obtained by a special process (adding a release layer). In the folded state, a portion of the non-adhesive smooth surface of the release tape 51 faces the second end 32 of the flexible attachment 30, and another portion of the non-adhesive smooth surface of the release tape 51 faces the carrier 10. The surfaces of the non-adhesive film 14, the flexible attachment 30 and the hook 22 are also non-adhesive non-adhesive release surfaces. Therefore, in the folded state, the release tape 51 is easily separated from the flexible attachment member 30 and the non-adhesive film 14 or the hook member 22, so that the folded adhesive member 50 is bounced open to generate a flashing phenomenon.
[0036] When the hook component 1A is mounted to the mounting portion 40 of the terminal product, the adhesive portion 50 is pivoted and unfolded, the adhesive layer 52 faces the carrier 10, and the mounting portion 40 of the terminal product is sandwiched between the first adhesive layer 12 and the adhesive layer 52. Figure 5 shown.
[0037] In the hook components of other comparative examples, the folding pivot portion does not have Figure 4-5The adhesive layer 52 shown in FIG. This makes it possible that when the hook component of this comparative example is unfolded, the portion where the folded pivot portion overlaps with the mounting portion of the terminal product is a smooth anti-adhesive surface, without a fixing effect, and thus easily causes the terminal product to loosen, for example, causing side leakage when the terminal product is a diaper.
[0038] In contrast, in the hook component 1 according to the present invention, the second adhesive layer 23 is provided on the second surface of the body portion 21 of the fastener 20, and the fastener 20 is configured as the folding pivot portion of the hook component 1 as described above. With the above configuration, on the one hand, it is not necessary to provide the adhesive portion 50 in the hook component 1A of the comparative example. Therefore, the length of the hook component 1 in the hook portion 1A can be significantly shortened. Figure 1 The length in the direction L in the middle. For example, in one example, the length of the hook component 1A of the comparative example is 62 mm. When the fastener 20 and the handle film 13 of the hook component 1 according to the utility model have the same length and interval as the fastener 20A and the handle film 13 of the hook component 1A of the comparative example, the length of the hook component 1 according to the utility model can be reduced to 42 mm because the adhesive portion 50 is not required. In addition, compared with the hook component 1A of the comparative example, the release tape 51 is not required, so the structure of the hook component can be simplified, and materials can be saved and costs can be reduced. On the other hand, in the folded state, the hook-shaped member 22 of the fastener 20 faces the first adhesive layer 12 of the carrier 10 and can contact the first adhesive layer 12, so that the hook-shaped member 1 can be stably in the folded state without being bounced open, thereby avoiding the flash phenomenon. Furthermore, when installed in place, the second adhesive layer 23 on the fastener 20 adheres to the surface of the mounting portion 40 of the terminal product, and the second adhesive layer 23 has a fixing effect, which is beneficial for the hook component 1 to be connected to the mounting portion 40 of the terminal product without causing looseness.
[0039] The hook component 1 according to the first embodiment of the present invention has been described above.
[0040] exist Figure 1-3 In the example shown in , the first adhesive layer 12 and the second adhesive layer 23 are respectively bonded to the opposite side surfaces of the flexible attachment 30, and in the folded state, the flexible attachment 30 is folded into a C shape. However, the present invention is not limited thereto, and in other examples according to the present invention, the first adhesive layer 12 and the second adhesive layer 23 can be bonded to the same side surface of the flexible attachment 30. For example, Figure 6 A hook component 1B according to a modified example of the present utility model is shown. Figure 1-3 The configuration of the hook component 1 shown in FIG. 1 is substantially the same, except that the first adhesive layer 12 and the second adhesive layer 23 can be bonded to the same side surface of the flexible attachment 30B. Figure 6As shown, the first adhesive layer 12 and the second adhesive layer 23 are both bonded to the surface 35 of the flexible attachment 30B. Specifically, a portion of the second adhesive layer 23 is bonded to the surface 35 of the first end 31 of the flexible attachment 30B, and a portion of the first adhesive layer 12 is bonded to the surface 35 of the second end 32B of the flexible attachment 30B, so that in the folded state, the flexible attachment 30B is generally S-shaped, and the first surface of the body portion 21 of the fastener 20 (that is, the surface provided with the hook-shaped member 22) faces the carrier 10 but not the flexible attachment 30, and when the fastener 20 is folded along Figure 6 When pivotally unfolded in the direction indicated by arrow A in FIG. 1 , in the unfolded state, the flexible attachment 30 is folded so that one portion is overlapped on another portion, for example, the first end portion 31 is overlapped on the second end portion 32B.
[0041] exist Figure 1-3 In the example shown in , a handle film 13 is provided on the carrier 10 and is spaced apart from the second end 32 of the flexible attachment 30, and the handle film 13 forms a finger lift area of the carrier 10. However, the utility model is not limited thereto. In other examples according to the utility model, the flexible attachment 30 may be long enough so that in the folded state, the second end of the flexible attachment 30 extends beyond the end of the fastener 20, and the hook-shaped members 22 of the fastener 20 all face the surface 35 of the flexible attachment 30. The second end of the flexible attachment 30 acts as a handle film, so that there is no need to provide a handle film 13 separately. In another example according to the utility model, the handle film 13 may be in contact with the second end 32 of the flexible attachment 30 or be formed as one body with the flexible attachment 30. In another example according to the utility model, the end of the surface 11 of the carrier 10 may be provided with a non-adhesive area, and the non-adhesive area forms a finger lift area of the carrier 10. For example, the first adhesive layer 12 is not provided at the end of the surface 11 of the carrier 10, so that the surface 11 of the end of the carrier 10 without the first adhesive layer forms a finger lift area. The above modified example of the utility model can still achieve similar beneficial effects as described above, and can shorten the length of the hook component 1 and simplify the structure of the hook component 1.
[0042] In the example shown in the figure, the second end 32 of the flexible attachment 30 and the handle film 13 are spaced apart from each other on the surface 11 of the carrier 10, and the first adhesive layer 12 is continuously disposed on the surface 11 of the carrier 10. However, the present invention is not limited thereto. In other examples according to the present invention, the surface 11 of the carrier 10 may further include a non-adhesive area, which is located between the second end 32 of the flexible attachment 30 and the handle film 13. Thus, in this modified example, in the folded state, at least a portion of the hook-shaped member 22 of the fastener 20 faces the surface 11 of the carrier 10 and contacts it. This modification still achieves the above-mentioned beneficial technical effects of shortening the length of the hook component 1 and simplifying the structure of the hook component 1, and when the carrier 10 is made of a non-woven fabric having a fiber structure, it can still be stably in the folded state.
[0043] Figure 7 An example of a hook and loop coupling product (i.e., an end product) 100 using the hook and loop coupling assembly according to the present invention is shown. The hook and loop coupling assembly includes a hook component 1 and a corresponding loop component 2. The hook and loop coupling product 100 includes a product body, which includes a first mounting portion 60 and a second mounting portion 70. The hook component 1 is mounted to the first mounting portion 60, and the loop component 2 is mounted to the second mounting portion 70. The hook-shaped member 22 of the fastener 20 of the hook component 1 can be releasably coupled with the loop-shaped member (not shown in the figure) of the loop component 2 to couple the first mounting portion 60 of the product body with the second mounting portion 70.
[0044] In the example shown in the figure, the hook-and-loop connection product 100 is a disposable diaper. The first mounting portion 60 is the diaper lugs on both sides of the rear waist of the diaper, and the second mounting portion 70 is the front outer surface of the diaper. However, the present invention is not limited thereto. In other examples according to the present invention, the hook-and-loop connection product 100 using the hook-and-loop connection assembly according to the present invention can be other wearable products, for example, disposable surgical gowns or other disposable clothing.
[0045] The above uses the application of the present invention in diapers as an example to illustrate the hook component, hook and loop connection assembly and hook and loop connection product according to the preferred embodiment of the present invention. However, it should be understood that the present invention is not limited to the specific embodiments described and shown in detail above. Without departing from the main purpose and scope of the present invention, those skilled in the art can make various modifications and variations to the present invention. All these modifications and variations fall within the scope of the present invention. Moreover, all components described herein can be replaced by other technically equivalent components.
