Patent Nov. 11, 1975 FLUID-TIGHT FASTENER This invention relates to improvements in resilient fasteners that provide flexible closures of a variety of different uses such as on brief cases, pouches, wrappers, and the like, and is specifically concerned with a new and improved fluid-tight fastener.
As heretofore constructed resilient fasteners of the type of the generally interlocking rib and groove structure, sometimes also referred to as slide fasteners, have generally been constructed with some looseness in the assembly. Representative of this type of fastener in the prior art is Madsen US. Pat. No. 2,713,421 wherein clearance is provided over the crowns of the ribs to enable the fastener strips to engage more readily as well as to permit relative sliding movement longitudinally between the strips.
Fasteners as just described are not leak proof so that where a fluid-tight (either vapor or liquid) closure is required some other type of closure would be required, although a resilient fastener might be more convenient and advantageous.
One manner of solving the problem is represented in prior patent to Staller U.S. Pat. No. 3,440,696. Therein is disclosed the provision of a relatively soft sealing thermoplastic substance placed under compression during engagement of the rib and groove elements. However, that solution complicates manufacture of the fastener, requiring bringing together of materials of different durometer characteristics, rather than making the fastener from a single material as is conventional practice.
Accordingly, there has been a long felt need for a fluid-tight fastener which will provide a vapor lock or hermetic seal, but which can be manufactured according to conventional practices comprising extruding the parts from a suitable plastic material of uniform characteristics suitable for the intended purpose.
An important object of the present invention is to provide a new and improved resilient fluid-tight fastener which may be used as a closure for pouches, containers, wrappers, and the like, for enclosing articles and substances that must be protected against atmospheric, water or other deteriorating conditions or, on the other hand, must retain within the enclosure a fluid substance without any leakage hazard.
Another object of the invention is to provide a new and improved fluid-tight fastener which automatically provides a fluid barrier between sheeting sections upon securing interlocking groove and fastener elements secured thereto.
A further object of the invention is to provide a new and improved resilient fastener wherein a novel tensioning and compression relationship is provided in the closed fastener such that the elements thereof provide with the other portions of the fastener a fluid-tight barrier.
Still another object of the invention is to provide a new and improved fluid-tight fastener which can be manufactured according to conventional techniques from preferred conventional materials and to be manipulated into closed and open conditions by conventional means, but which automatically seals against fluid leakage therethrough in the assembled condition of the fastener.
Other objects, features and advantages of the invention will be readily apparent from the following description of certain preferred embodiments thereof, taken in conjunction with the accompanying drawing although variations and modifications may be effected without departing from the spirit and scope of the novel concepts embodied in the disclosure, and in which:
FIG. 1 is a fragmentary sectional isometric view illustrating a fluid-tight fastener embodying features of the invention;
FIG. 2 is an exploded assembly view of the fastener showing the same with the complementary portions thereof separated and schematically illustrating certain features contributing to the new and improved results attained with this fastener;
FIG. 3 is an enlarged sectional view through the fastener assembled together and schematically illustrating how the parts of the fastener stretch in the assembly to attain the desirable compressive sealing reaction therein; and
FIG. 4 is a transverse sectional view showing a modification.
On reference to FIG. 1 a fluid-tight fastener 5 embodying features of the invention is depicted comprising a pair of complementary flexible closure strips 7 and 8 each of which has a web portion 9 provided with a marginal strip portion 10. Although the web portion 9 and the marginal strip portions 10 may be constructed from different materials, but with at least the marginal strip portions 10 formed from strongly resilient material, in the construction shown both the web portions 9 and the marginal strip portions 10 are formed integrally in one piece as an extrusion made from a suitable durometer thermoplastic material. Relative flexing movement between the portions 9 and 10 of each of the strips is facilitated by the provision of a longitudinal groove 11 between the web portion 9 and the marginal strip portion 10 in each instance.
For separable interlocking of the marginal strip portions 10 they are provided with respective, complementary longitudinal interlocking ribs 12 and grooves. 13. Each of the marginal strip'portions 10 is provided with at least one rib 12 and one groove 13, but in a preferred arrangement as shown, each of the marginal strip portions has two ribs and corresponding grooves. Each of the ribs 12 has arcuate sides generally complementary to arcuate sides of the groove 13 in which received, and an undercut tooth formation 14 along one side thereby forming an enlarged head and which is complementary to and releasably interlockingly interengagable with the like tooth along one side of the groove 13, provided by the head of the counterpart rib 12 in the fastener assembly.
According to the present invention, the construction and relationship of the interlocking ribs 12 and grooves 13 is such that in the assembled relationship the ribs 12 are sealingly gripped in fluid-tight relation within grooves 13. For this purpose, the ribs 12 are of solid form-retaining, construction (although resiliently flexible) and are wider than the normal width of the grooves 13 so that the ribs as received in the grooves cause the grooves to expand and areas of the marginal strip portions 10 at the grooves to stretch and react under tension to place the ribs 12 under compression. On reference to FIG. 2, for example, it will be observed by comparing the full line and the dash line representations of the strips 7 and 8 that the sides of the grooves in the unassembled normal condition of the marignal strip portions 10 are significantly narrower than the width of the ribs 12. Therefore, when the ribs 12 are forced into the grooves 13 until the teeth 14 interlock. the sides of the grooves 13 must move apart to accommodate the mass of the inserted ribs 12. This causes areas of the marginal strip portions at the grooves. and more particularly bridge portions 15 of the marginal strip portions 10 connecting the ribs 12 with one another and with the web portions 9 to stretch and elongate transversely, as indicated by the full line showing in FIG. 3 as compared to the dot-dash illustration therein. By reason of the resilient characteristics of the material of the fastener, such stretching causes a corresponding reaction due to the tension generated tending to pull the sides defining the grooves 13 back toward their normal position, resulting in placing the sides of, the ribs 12 under compression between the sides defining the grooves. As a result, the side surfaces of the ribs 12 and of the grooves 13 are in tight gripping relation and effectively hermetically seal the fastener 5.
To facilitate the stretching and tensioning of the bridges 15, the relative shape and relationship of root surfaces 17 in the grooves 13 and confronting crown surfaces 18 on the heads of the interlocking ribs 12 are so relatively shaped as to leave freedom of relative movement therebetween during the assembly of the ribs into the grooves. To this end, the root surfaces 17, in the grooves 13, are arched away from the ultimate position of the crown surfaces 18 and further, the crown surfaces 18 are relatively flattened so that a spaced relationship between the root surfaces and the crown surfaces persists after assembly has been completed. as is seenin FIGS. 1 and 3. It will be observed that while the crown surfaces 18 remain substantially in their original shape. the root surfaces 17 tend to flatten somewhat and pull in toward the crown surfaces 18 as the bridge areas 15 pull in toward said crown surfaces 18 by reason of the stretching of the bridge areas.
A reasonable degree of control upon the stretching characteristics of the bridge material of the interlocking marginal portions of the fastener may be effected by the thickness of the bridge in any instance. For example, in FIG. 4 the bridges 15 are shown in full line as substantially thinner than the bridges 15 indicated in dot dash line and corresponding to the bridges in the form of FIGS. 1-3. In other respects the fastener remains the same and therefore identical reference 'numerals indicate identical parts according to foregoing description. Thus by having the bridges 15 thinner, a softer easier stretch is attained. Of course, by the same token, by increasing the thickness of the bridge in any instance increased resistance to stretching and a tighter leak-proof grip on the interlocking ribs can be attained, though if the bridge is too thick, no stretching will be possible and the fastener will not close.
In any form of the invention, the fastener is adapted to be opened and closed by means of any preferred form of slider. When closed, a thorough hermetic seal is provided against internal or external leakage of fluid F, shown for illustrative purposes in FIG. 1 as a liquid on one side only of the fastener. The fluid F may, of course, be on both sides of thefastener where mixing or contamination of one fluid by another must be avoided as. for example. where a sealed package ,con-.
taining fluid must be stored or transported inanother fluid. Also. the fluid may be in a vapor or a gaseous phase or liquid phase.
' It will be understood that variations and modifications may be effected Without departing, from the spirit and scope of the novel concepts of this invention.
