Abstract
A modified adhesive zipper device. The device has two flexible stringers with rows of teeth and an adhesive substance coated on the flexible stringers. The device has a slider and one or two pull tabs for actuation of the slider. The device has stopping means that inhibit the ability of the pull tabs to rotate away from the longitudinal axis of the device, and thereby prevent contact between the pull tabs and the adhesive substance coated on the flexible stringers.
Claims18
An adhesive zipper device comprising:
- two flexible stringers
- where each of the flexible stringers is coated with an adhesive substance on at least one planar side of the device and the adhesive substance runs along the length of the stringers on said planar side, and where each of the flexible stringers is provided with a row of teeth attached to the stringer in staggered fashion along the abutting edges of the stringers;
- a slider
- having at least one pull tab connection member that rises from the planar surface of the slider on the same planar side of the device as the planar side on which each of the stringers are coated with adhesive substance, wherein the pull tab connection member has a transverse opening in said pull tab connection member, and where said slider also contains a Y-shaped internal channel in the center of the slider through which the rows of teeth may pass in order to be reversibly interlocked with each other as the slider is moved lengthwise along a longitudinal axis of the adhesive zipper device that is defined by the abutting edges of the two flexible stringers at the location where the rows of teeth are interlocked or disconnected inside the slider by actuation of the slider;
- a pull tab
- that is connected to the slider by a trunnion member that passes through the transverse opening in the pull tab connection member, and also having a pull tab opening that is an aperture through the pull tab that accommodates the body of the pull tab connection member that is disposed within the pull tab opening;
- pull tab stopping means
- that inhibit rotation of the pull tab away from the longitudinal axis of the adhesive zipper device and thereby inhibit rotation of the pull tab toward the stringers and prevent contact between the pull tab and the adhesive substance coated on the stringers;
- and
An adhesive zipper device comprising:
- two flexible stringers
- where each of the flexible stringers is coated with an adhesive substance on at least one planar side of the device and the adhesive substance runs along the length of the stringers on said planar side, and where each of the flexible stringers is provided with a row of teeth attached to the stringer in staggered fashion along the abutting edges of the stringers;
- a slider
- where said slider contains a Y-shaped internal channel in the center of the slider through which the rows of teeth may pass in order to be reversibly interlocked with each other as the slider is moved lengthwise along a longitudinal axis of the adhesive zipper device that is defined by the abutting edges of the two flexible stringers at the location where the rows of teeth are interlocked or disconnected inside the slider by actuation of the slider;
- and
- a pull tab
- that is rigidly connected to the slider by weld or by being molded or cut from the same piece of material as the slider such that rotation of the pull tab away from the longitudinal axis of the adhesive zipper device is prevented and thereby rotation of the pull tab toward the stringers is also prevented.
The method of using an adhesive zipper device to open and close openings within pieces of flexible material wherein the adhesive zipper device is provided with means for preventing a pull tab of the adhesive zipper device from rotating away from the longitudinal axis of the adhesive zipper device and coming into contact with the adhesive portions of the adhesive zipper device.
