Abstract
Reclosable zippers for reclosable packages are disclosed. The zippers include male and female profiles. The female profiles are periodically inwardly and/or upwardly deformed in order to generate tactile and audible feedback when the zippers are opened or closed by the user. The deformation of the female profiles typically maintains the strength of the zipper.
Claims23
A method of producing a zipper for a reclosable package, including the steps of:
- providing a length of first zipper profile including a male element;
- providing a length of second zipper profile including a female element, wherein the female element includes a space for receiving the male element;
- inwardly deforming segments of the female element whereby inwardly deformed segments alternate with undeformed segments along the length of second zipper profile;
- and
- wherein the step of inwardly deforming segments of the female element results in spacing between successive inwardly deformed segments wherein a distance between a first pair of adjacently successive inwardly deformed segments is different from a distance between a second pair of adjacently successive inwardly deformed segments.
