Abstract
An interlocking closure fastening device comprises a pair of elongate closure elements. One of the closure elements has a barbed surface along a portion thereof. A second closure element includes a complemental surface that, when mated with the first surface, provides a perceptible tactile sensation.
Description
- The present invention relates to interlocking closure strips, and more particularly, an interlocking fastening strip that includes at least one barbed closure element particularly adapted for use with reclosable plastic storage bags.
- Known closure fastening devices used in conjunction with thermoplastic reclosable containers provide an effective seal of the contents in the container when the fastening device is placed in a closed position. Such fastening devices typically comprise a pair of complementary closure strip elements that extend longitudinally along the upper portions of opposed sidewalls of the containers. The closure elements are constructed such that they interlockingly engage with each other in a closed or occluded position, while at the same time permitting relatively easy disengagement of the closure elements when the container is opened from the outside.
- One desirable feature of many such fastening devices is that they enable the user to determine the state of closure of the fastening device. For example, one known arrangement provides a visual indication of the closure state of the fastening device with the use of various colorations of the opposed closure elements. One such arrangement is disclosed in U.S. Pat. No. 4,829,641. When the opposed closure elements are interlocked, the user perceives a third distinct coloration of overlapping element portions indicative of proper closure of the container.
- Other conventional techniques utilize a particular tactile “feel” provided to the user of the container to indicate closure of the container. For example, U.S. Pat. No. 5,070,584 discloses a zipper arrangement that provides the perception of a “bumpy” feel. The zipper arrangement includes a pair of opposing interlockable rib and groove profiles where one of the profiles has a plurality of indentations spaced longitudinally therealong. These indentations purportedly provide an audible clicking sound or bumpy feel that is perceptible to the user as the cutout or weakened portions flex during closure.
- The present invention provides a fastening closure strip for use with a reclosable storage container that comprises a pair of interlocking closure elements. The fastening closure strip has a multiple position feature. In accordance with this invention, the user can move the closure strip from one position to another position. The engagement surfaces of the closures are referred to herein as barbed surfaces owing to the multiplicity of their engagement surfaces. One form of such engagement surfaces are often referred to as hooks. Accordingly, references herein to “hooks” are intended to refer to one type of a barb for use in this invention. At least one of the closure elements has a barbed surface to provide the user of the storage container a distinctive tactile “feel” when the container is closed.
- Structurally, a closure fastening device according to the present invention comprises a pair of opposed, longitudinally extending closure strip elements adapted to interlockingly engage with each other a fully occluded mode. One of the closure element strips includes a plurality of barbs extending from an upright peripheral segment of the closure strip. The second closure element includes a complemental segment that intermittently engages the barbs as the closure elements are moved to the fully occluded mode upon the application of compression forces. This manner of engagement provides a ratcheting sensation to the user of the interlocking closure device.
- In one embodiment, the first closure element strip comprises a base portion having a pair of spaced-apart, elongate first webs extending therefrom. The webs each include a male hook member extending outwardly from each of the respective webs. The second closure element similarly comprises a pair of webs extending from a second base portion. The second webs include a plurality of spaced-apart female barbs that extend inwardly to permit intermittent ratcheting engagement with the corresponding hook members when the fastening device is moved from a deoccluded mode to the occluded mode.
- The invention may also be embodied in a closure fastening device comprising a first male closure element that includes a base portion having a pair of spaced-apart, elongate first webs extending therefrom. In this embodiment, the first webs each include a plurality of spaced-apart male barbs extending outwardly from each of the webs. The fastening device includes a female closure element having a pair of second webs extending from a second base portion. At least one of the second webs include a female hook member that extends inwardly to permit intermittent ratcheting engagement with the corresponding male barbs when the fastening device is moved from a deoccluded mode to the occluded mode.
- In yet another embodiment, a closure fastening device comprises a male closure element with a pair of webs in the form of a serpentine profile configuration to provide a substantial wave like surface. This profile configuration forms a plurality of interleaved protrusions and corresponding depressions. The device further comprises a complementary female closure element including a pair of second webs, each of which has a female hook member adapted to intermittently engage the protrusions of the serpentine profile configuration.
- Other advantages and embodiments of the invention will be apparent to those skilled in the art upon consideration of the following detailed description and appended claims, and upon reference to the accompanying drawings.

male hook members FIG. 4B . In this way, the closure elements interlock in an interdigitating step-wise fashion until they are fully occluded, as shown inFIG. 5A . Accordingly, a ratcheting engagement of the male hook members with the barbs that is perceptible to the user occurs as the closure elements are urged together in an interdigitating fashion. In addition, this manner of ratcheting engagement generates an audible sound at each instance in which the hook member disengages from one of the barbs and is located within the notches formed therebetween due to the interdigitating nature of the opposed webs. The sound is caused by the ratcheting or snapping of the hook into the notch which results from the release of the flexure force of the hook. This sound is likewise readily perceptible by the user during a closure operation. - Preferably, each such intermittent engagement of the male hook elements with respective ones of the barbs provides sufficient interlocking engagement of the closure elements to maintain closure of the container. In most instances, however, the user will fully occlude the opposed closure members, in part due to the audible sound generated by the fastening device.
