Claim:
A device for forming an endless seal, comprising: (a) an endless upper seal member having a first mating surface and a lifting wing, wherein said endless upper seal member includes a gap section wherein said lifting wing is not present; (b) an endless lower seal member having a second mating surface and a closure bar groove, wherein said second mating surface interlocks with said first mating surface; and (c) a slider moveable along said endless upper and lower seal members for interlocking said first mating surface to said second mating surface, thereby forming the endless seal, said slider including: (i) a lifting rib slidably cooperating with said lifting wing of said endless upper seal member; (ii) a closure bar slidably cooperating with said closure bar groove of said endless lower seal member; and (iii) a body having a closing end wherein said lifting rib is in closing proximity with said closure bar, and an opening end wherein said lifting rib is in opening proximity with said closure bar; wherein said slider is moveable along said endless upper seal member and said endless lower seal member to pass said upper and lower seal members within said slider from said opening end to said closing end, said slider moveable from a start position along a length of said endless upper and lower seal members to an end position, wherein said end position is located at at least one of: (A) said start position, and (B) substantially adjacent to said start position, and wherein said slider confines said first mating surface into contact with said second mating surface thereby forming the endless seal.
