In the embodiment shown in FIGS. 5 and 6, the slider 20 a rides on longitudinal projections 80 and 82 on the second zipper part 24 a. These projections, which serve as rails, are mutually parallel and lie in a horizontal plane. The slider 20 a comprises respective linear grooves 76 and 78 for receiving the projections 80 and 82. Groove 76 is formed in the second side wall 60 and opens at its interior surface, while groove 78 is formed in the first side wall 58 and opens at its interior surface. Each of grooves 72, 76 and 78 extends from the closing end to the opening end of the slider 20 a.
FIG. 10 is a schematic showing a side view of a slider 20 a parked adjacent a slider end stop 98 on the flexible zipper depicted in FIG. 5. In conventional manner, slider end stops are formed on both ends of the zipper by crushing or stomping the ends of the zipper parts 22 a and 24 a together. The end stops both prevent the slider from sliding off the end of the zipper and join the zipper parts 22 a and 24 a at their ends to hold the zipper together. Near the end stop 98, a terminal portion of the projection 74 on the male zipper part 22 a can be removed (in the area designated 100, which lies behind the slider wall) to allow the full length of the zipper to close even when the slider is in the fully closed position.
front and rear walls disposed on opposing sides of a vertical plane;
first and second zipper parts respectively joined to said first and second walls;
means for displacing said first zipper part relative to said second zipper part in a direction generally parallel to said vertical plane; and
a slider mounted to said second zipper part, wherein said slider comprises a top wall and first and second side walls connected to said top wall, and said displacing means comprise a groove and a projection residing in said groove, one of said groove and said projection forming part of said second side wall of said slider and the other of said groove and said projection forming part of said first zipper part.
2. The package as recited in claim 1, wherein said groove is formed in said second side wall of said slider, said groove being inclined relative to said top wall.
said zipper comprises a first zipper part comprising a first interlockable element and a second zipper part comprising a second interlockable element, said first and second interlockable elements being mutually interlocked as said slider is moved along said zipper in a first direction to close a mouth in a top of said receptacle and being mutually disengaged as said slider is moved along said zipper in a second direction opposite to said first direction to open said mouth; and
said slider comprises a top wall and first and second side walls connected to said top wall, an opening end, and a closing end, said second zipper part passing between said first and second side walls and under said top wall of said slider,
wherein a section of said first zipper part moves vertically downward, away from said top wall of said slider and out of engagement with an opposing section of said second zipper part, during slider movement in said second direction, and moves vertically upward during slider movement in said first direction, and
wherein said first zipper part comprises a projection projecting from one side thereof and extending along a major section of said first zipper part, and said slider comprises a groove that is engaged with said projection of said first zipper part during slider movement along said zipper, said first groove being inclined relative to said top wall of said slider.
7. The package as recited in claim 6, further comprising means for providing that said section of said second zipper part does not move vertically relative to said slider during slider movement along said zipper.
said zipper comprises a first zipper part comprising a first interlockable element and a second zipper part comprising a second interlockable element, said first and second interlockable elements being mutually interlocked as said slider is moved along said zipper in a first direction to close a mouth in a top of said receptacle and being mutually disengaged as said slider is moved along said zipper in a second direction opposite to said first direction to open said mouth,
a section of said first zipper part moves vertically downward, away from said top wall of said slider and out of engagement with an opposing section of said second zipper part, during slider movement in said second direction, and moves vertically upward during slider movement in said first direction, and
the package further comprising first and second grooves that are mutually parallel and first and second projections respectively seated in said first and second grooves, wherein two of said first and second grooves and said first and second projections form part of said slider and the other two of said first and second grooves and said first and second projections form part of said second zipper part.
15. An assembly comprising a zipper, a slider mounted to said zipper, said zipper comprising first and second zipper parts that are mutually interlockable, and said slider comprising a top wall generally perpendicular to a vertical direction, first and second side walls connected to said top wall, and a mechanism for vertically displacing said first zipper part relative to said second zipper part, said first and second zipper parts being mutually interlocked as said slider is moved along said second zipper part in a first direction and mutually disengaged as said slider is moved along said second zipper part in a second direction opposite to said first direction, and first and second grooves that are mutually parallel and first and second projections respectively seated in said first and second grooves, wherein two of said first and second grooves and said first and second projections form part of said slider and the other two of said first and second grooves and said first and second projections form part of said second zipper part.
