Abstract
An apparatus and method for operably mounting a slider onto a recloseable plastic zipper closure includes a rotor having at least one slider-engaging shoulder; an insertion wedge adjacent to the rotor and sized to slidably accommodate the slider for mounting onto a zipper closure; and a zipper guide member adjacent to the rotor and adjacent to the insertion wedge for guiding and holding a zipper closure while the slider is mounted thereon. The insertion wedge will have a leading edge and a trailing edge and increase in thickness from the leading edge to the trailing edge. The apparatus can be vertically oriented or horizontally oriented.
Claims22
An apparatus for operably mounting a slider onto a recloseable plastic zipper closure, the apparatus comprising:
- (a) a rotor having an outer periphery and at least one slider-engaging shoulder extending from the outer periphery;
- the outer periphery having a slot therealong sized to accommodate a zipper closure therein;
- (i) a pair of opposing walls being on opposite sides of the rotor;
- and
- (ii) an insertion pocket being defined by the outer periphery of the rotor and the opposing walls, the insertion pocket being sized to hold a slider;
- (b) an insertion wedge adjacent to a portion of the outer periphery of the rotor;
- the insertion wedge having a leading edge and trailing edge and increasing in thickness from the leading edge to the trailing edge;
- the insertion wedge sized to slidably accommodate a slider for mounting onto a zipper closure;
- and
- (c) a zipper guide member adjacent to the outer periphery of the rotor and adjacent to the trailing edge of the insertion wedge constructed and arranged to guide and hold a zipper closure while a slider is mounted thereon.
An apparatus for operably mounting a slider onto a recloseable plastic zipper closure, the apparatus comprising:
- (a) a rotor having an outer periphery and at least one slider-engaging shoulder extending from the outer periphery;
- the outer periphery having a slot therealong sized to accommodate a zipper closure therein;
- (i) the rotor including at least two slider-engaging shoulders;
- (ii) the rotor including at least two sections, each section having a variable curvature radius that increases continuously between a first radius and a maximum radius coinciding with one of the shoulders;
- (b) an insertion wedge adjacent to a portion of the outer periphery of the rotor;
- the insertion wedge having a leading edge and trailing edge and increasing in thickness from the leading edge to the trailing edge;
- the insertion wedge sized to slidably accommodate a slider for mounting onto a zipper closure;
- and
- (c) a zipper guide member adjacent to the outer periphery of the rotor and adjacent to the trailing edge of the insertion wedge constructed and arranged to guide and hold a zipper closure while a slider is mounted thereon.
