Abstract: Disclosed is a device for creating a seal which includes an upper seal member, a lower seal member, and a slider, wherein mating surfaces of the upper and lower seal members interlock. A lifting rib on the slider cooperates with a lifting wing on the upper seal member and a closure bar cooperates with a closure bar groove of the lower seal member. By moving the slider in one direction, the lifting rib lifts the upper seal member from its interlocking relationship with the lower seal member. Moving the slider in the opposite direction causes the upper and lower seal members to interlock. Also disclosed is a seal device which includes upper and lower seal members and a cooperating slider and plug. Each of the slider and plug cooperate with first and second mating surfaces of the upper and lower seal members. In addition, the slider and plug have an exterior tongue and groove portion which cooperate to interlock the slider and the plug.

Abstract: A zipper (10) having interlocking profiles (16, 20) wherein the male profile (16) has at least two male ribs (26, 30) bordering a male rib (28). The male profile (16) is engagable with a female profile (20), wherein the female profile (20) includes grooves (38, 48). The grooves (38, 48), attached to each other by a bridge (54), engage the male ribs (26, 32). With the profiles (16, 20) engaged, the male rib (28) pushes against the bridge (54) and thereby pushes the bridge against the packaging film during attachment such that the profiles (16, 20) are stabilized during sealing to the packaging film. As part of a pre-made zipper (10), the male rib (28) can be attached to the bridge (54) to form a barrier seal within the zipper (10).

Abstract: The closure device includes interlocking first and second fastening strips. The first fastening strip includes a closure element extruded onto a flange portion. The closure element and the flange portion are composed of materials having different densities to control the shape of the fastening strips. The purpose of changing the densities of the material is to reduce or eliminate the curve in the fastening strips which occurs during the manufacturing process. By providing a lower density material for the closure element, which has a greater volume, and by providing a higher density material for the flange portion, the flange portion will crystallize at the same rate as the closure element. This difference in densities results in a reduction or elimination in the curvature of the fastening strips.

Abstract: A closure device for a thermoplastic bag which includes two opposing, longitudinally extending interlockable male and female fastening strips having respective male and female closure elements or profiles that are deformed to interdigitate and produce an audible clicking sound and or tactile effect that is perceptible to the touch as the closure device is opened and closed. Interdigitation of the two profiles is achieved by cold forming the profiles while interlocked. The shape of the cold form is a stepped deflection of both profiles so that their shapes are generally congruent. The stepped deflections provide a change in the occlusion and peel force of the interlocking closure device thereby resulting in an audible clicking or popping sound as the closure device is opened and closed and a tactile effect that is perceptible to the touch as the closure device is closed.

Abstract: The present invention provides a flexible storage bag having an opening, a closure system for the opening, and a closure indicator. The closure indicator provides an audibly detectable signal upon closure, and optionally opening, of the closure system. The closure system may provide a seal which is preferably closed by a translatable slider as is known in the art. The translatable slider may intercept protuberances causing the protuberances to produce a snap or clicking sound as the slider passes over the protuberances. Alternatively, the closure indicator may be an adhesive bond which is disrupted by the translation of the slider. The closure indicator is passive, meaning that no additional action beyond the ordinary and commonly accepted movement of the slider is required to produce the audible signal.

The fastening strips (130, 131) are occluded and deoccluded by moving the first fastening strip relative to the second fastening strip in substantially the vertical Z axis (164). The fastening strips may also move in the Y axis (162), rotate or deflect during occlusion. In addition, the fastening strips may include a locking feature (1244, 1245) to prevent unintentional deocclusion.
