Abstract
A cap and container especially suited for dispensing liquids has a cap which is accurately aligned upon closure. The container is closed by applying downward axial pressure to the cap, thereby forcing lugs in the cap to pass over threads located on the neck of the container so that the cap is snapped on. Stop walls prevent any undesired cap rotation. Stabilizing lugs are alternatively provided to add additional stability. Alternatively, the container is closed by twisting or rotating the cap with respect to the neck. The cap may also be twisted or snapped off. Modifications in the neck configuration make the cap irremovable.
Claims10
A container and cap closure therefor comprising:
- (a) a container having a generally cylindrical neck including a bore therethrough for dispensing liquids;
- (b) a cap closure for closing said bore including a closed end and an outer annular skirt depending therefrom and adapted to fit over said neck;
- and
- (c) retaining means on said neck and skirt permitting said cap closure to be snapped on and off as well as rotated on and off said neck, said retaining means comprising:
- (i) at least one thread on said neck;
- and
- (ii) at least one retaining lug having a horizontal top surface on the interior of said skirt having a beveled area at the bottom tapering substantially to the innermost edge of said top surface adapted to ride over said thread when snapped onto said neck, said skirt and retaining lug being made of resilient material so that they may deform as they pass over said thread when said cap closure is snapped on or off said neck;
- (iii) at least one retaining groove on said neck, said at least one retaining lug cooperating with said at least one retaining groove and said thread so as to axially retain said cap closure on said neck;
- and
- (d) positioning means on said neck for positioning said cap closure with respect to said neck whereby said cap closure will be automatically positioned in the same orientation on said neck when said cap closure is fully engaged;
- and
- (e) stabilizing means comprising at least one stabilizing recess in said cap closure, at least one mating stabilizing lug on said neck adapted to closely fit within said at least one stabilizing recess for stabilizing and orienting said cap closure with respect to said neck, said at least one stabilizing lug spaced about 90.degree. around said neck from said at least one retaining groove so as to maximize the stabilizing effect, wherein said at least one stabilizing lug defines a generally curved radially outermost wall bounded laterally by a pair of generally vertical, lateral side walls.
