It is also possible to make it exist. The locking tab 22 is configured to form a disengagement ratio of at least 1.5: 1. Will be done. As used herein, the disengagement ratio is the disengagement of a fixed tab design. Strength (in grams / linear inches) and formed from the same material but odor Of the ratio of the disengagement strength (in grams / linear inches) of the rectangular rectangular fixing tabs Say that. The method by which the disengagement ratio is determined is described in detail below with examples. There is. Many mechanical fastener elements are commercially available for use in disposable absorbent products Has sufficient shear strength to be practical. Shear strength as used herein Is the force with which the mechanical fastener elements oppose each other in the plane of attachment of the element. Separate mechanical fastener elements (such as hook loop material) when receiving It is the force required to make it work. However, with many mechanical fastener elements, with respect to disposable absorbent products Such materials have peel strength that is not sufficient for commercial use. As used herein, peel strength is when one element receives a peeling force. Needed to separate mechanical fastener elements (such as hook loop material) It refers to the power to be done. Applicants have developed to design fixed tabs that retain improved peel strength. I came. In particular, Applicants are less likely to separate the elements during the separation mode separation. Fastener tabs so that at least some fastener tabs are placed in shear mode I figured out to change the design of. That is, the predetermined mechanical fixing tab is sheared. It's easier (with less force) to disengage in peel mode than in disconnect mode Therefore, when the applicant receives the peeling mode force, the mechanical fastener is applied. -Set up fixing tabs designed so that the elements are placed in shear mode before separation I figured out to measure. A typical fixing tab is generally on almost the entire surface of the substrate on which the fixing tab is formed. Adopt a nearly rectangular or square piece of mechanical fastener element mounted across To. By changing the shape of the mechanical fastener element existing on the fixing tab Therefore, the applicant can increase the strength of disengagement of the fixing tab. Peel Due to this increase in release strength, engagement, as described in detail below with respect to the example. The amount is determined as the release ratio. Therefore, the user end of the fixing tab of the present invention is at least 1.5: 1 and also Is at least 2: 1, or at least 5: 1, or at least about 10: It is configured to have a disengagement ratio of 1 and at least 15: 1. 3 to 13 illustrate specific fixed tabs for the present invention.

Central splinter 42 and sides The shape with the splinters 44, 46 is the valley in the mechanical fastener element (hook 40). It is designed to form part 48. Applicant is the valley portion 4 in a mechanical fastener element such as hook 40 The valley of the mechanical fastener element is at least about 5 millimeters for the 8 to be formed Torr, or at least about 8 mm, or at least about 15 mm Creates an disengagement ratio of at least about 1.5: 1 when having a depth of 50 I discovered that it was going to happen. In addition, side splinters 44, 46 are centerline 5 Approximately 0 ° to approximately 6 at mechanical fastener element 40 with respect to 2 and the inner surface of the side splinter Appropriately form an angle α of 0 °. Or are the side splinters 44, 46 about 10 °? Form an angle at the mechanical fastener element of about 55 °. The valleys and horns mentioned above Machine by forming mechanical fastener element 40 to form degree α In the peeling mode from the mechanical fastener element that engages the target fastener part 40 Is removing by removing the central splinter 42 exerting force in peel mode? Instead, it turns out that the side splinters 44, 46 are in shear mode. It was. As mentioned above, this has a disengagement ratio of 1.5: 1 or higher. It turns out to create a mechanically fixed tab to do. Form an angle α of about 10 ° or more This has been found to help separate the mechanical fastener elements. FIG. 4 represents another embodiment of the fixing tab according to the present invention. In Figure 4, Figure 3 The same numbers are given to similar elements of the fixing tabs shown in. See Figure 4 again When illuminated, the angle α formed in the valley 48 and the mechanical fastener element is 1. It has been found to produce fixed tabs with a disengagement ratio of 5 or more. The valley 48 shown in FIG. 4 has a valley bottom 54 that is substantially perpendicular to the center line 52. During ~ The existence of the valley bottom 54 perpendicular to the core line 52 means that the valley bottom 54 is formed. No Increased disengagement ratio compared to similar embodiments as illustrated in FIG. I understood. FIG. 5 illustrates a tab for fixing multiple splinters as shown in FIGS. 3 and 4. Figure 5 The fixing tab has 3 pieces (3 pieces), 42 pieces in the center, and 44 and 46 pieces in the side. Form.
