Vacuum press fit zipper assembly
A vacuum press fit zipper assembly designed for watersports apparel and gear and other water related applications. Overmolding construction forms an effective seal around the entire perimeter of the fastener assembly, and a vacuum fit is created between the two mating portions of the zipper assembly.
1. A watertight, vacuum press fit zipper assembly, comprising:
a fastener assembly made up of:
a female extrusion for matingly engaging a male extrusion to form a watertight, vacuum seal;
said female extrusion includes a substantially flat portion terminating in an upstanding female member extending therefrom, said female member having a C-like configuration with a slide extension protruding from an external surface thereof, said female member further having a cavity formed in the interior of the C-like configuration, said cavity extending from an elongated entrance opening and terminating in a bulbous or bulb-like opening forming a socket, the entrance opening of said cavity having opposed flat surfaces, and said C-like configuration having curved external portions extending from said flat surfaces;
said male extrusion includes a substantially flat portion terminating in an upstanding male member extending therefrom, said male member having a protruding stem on one side thereof and a slide extension protruding from an external surface on the other side thereof, said stem of said male member terminating in a bulbous or bulb-like section, the bulbous section having opposed flat surfaces, and having indentations that are reversely curved and terminating in tips to precisely mate with and cover the external curved portions of the female member to create a watertight, airtight seal; said bulbous section which protrudes from said stem of said male member is precisely shaped for matingly engaging with the bulbous-like cavity opening in the female member and creating a vacuum within said cavity and preventing capillary action from occurring when locked in place and when said flat surfaces of said female member and said male member, respectively, engage each other when said fastener assembly is closed;
a slider member for encompassing said female member and said male member, said slider member having internal opposed grooves therein for engaging said slide extensions on said female member and said male member, respectively; and
at least one pull tab operably connected to at least said female extrusion or said male extrusion to aid in the opening of said fastener assembly.
2. The watertight, vacuum press fit zipper assembly as defined in claim 1 further comprising a pair of end caps, each of said pair of end caps secured to opposite ends of said fastener assembly.
3. The watertight, vacuum press fit zipper assembly as defined in claim 1 wherein said substantially flat portion of said female extrusion and said substantially flat portion of said male extrusion are matingly formed within a garment or bag to permit said garment or bag to be opened and closed with a watertight seal.
