Abstract
A liquid storing and dispensing package comprising a bottle having a dispensing spout, a cap normally closing the dispensing spout for storage, and a push-in portion in the bottom of the bottle. A push rod has a head stored in the spout and responsive to actuation of the push-in portion to emerge with the spout and allow liquid dispensing. In one aspect of the invention, the push rod head can be refixed and resealed within the spout, by one hand of the user, to prevent further dispensing and to save part of the contents of the bottle for late dispensing, prior to the installation of the cap.
Claims18
A liquid dispensing package, suited for dispensing motor oil, comprising:
- a removable cap;
- a bottle comprising top and bottom walls and a peripheral wall connecting said top and bottom walls and defining therewith a storage chamber, an outlet spout protruding from said top wall and removably carrying said cap, said bottom wall including a flexible push-in portion substantially aligned with said spout, said push-in portion having an upstanding boss protruding into said chamber and an axially flexible, annular surround connecting said boss to the remainder of the bottle bottom wall, said boss having a storage position protruding a first distance into said chamber and a dispensing position extending a second, further distance into said chamber;
- a push rod in said bottle, said push rod having an elongate, generally longitudinally movable shaft extending between said push-in portion and spout, said push rod having a plug-like head fixed at the top portion of said shaft and having a storage position slidably disposed in the said spout and a dispensing position spaced outward from said spout, said push rod having a keeper member having a dispensing position in said bottle and limiting displacement of said head outboard beyond its said dispensing position, said push rod having a generally cup shaped base which opens toward said bottom wall and into which said boss telescopingly extends, said push rod base having an end wall opposing said boss and a peripheral skirt sleeved over said boss and axially opposing said axially flexible annular surround.
A liquid dispensing package, suited for dispensing motor oil, comprising:
- a removable cap;
- a bottle comprising top and bottom walls and a peripheral wall connecting said top and bottom walls and defining therewith a storage chamber, an outlet spout protruding from said top wall and removably carrying said cap, said bottom wall including a flexible push-in portion substantially aligned with said spout;
- a push rod in said bottle, said push rod having an elongate, generally longitudinally movable shaft extending between said push-in portion and spout, said push rod having a plug-like head fixed at the top portion of said shaft and having a storage position slidably disposed in the said spout and a dispensing position spaced outward from said spout, said push rod having a base which engages said push-in portion of said bottom wall, said push-in portion having storage and dispensing positions to which correspond storage and dispensing positions of said push rod, said outlet spout having a step facing into said chamber inboard of said storage position of said head, said push rod having a keeper member having a dispensing position in said bottle and limiting displacement of said head outboard beyond its said dispensing position, said keeper member comprising at least two evenly circumferentially spaced keeper portions axially spaced inboard of said head and axially opposing said step at an axial spacing corresponding to the axial spacing of said storage and dispensing positions of said head, said keeper portions having a common dispensing position simultaneously abutting said step and so maintaining said push rod blocked against tilting with respect to the length axis of said spout, said keeper portions in said dispensing position lying adjacent correspondingly evenly circumferentially spaced portions of said step and so maintaining said head substantially coaxial with said spout, whereby the flow of dispensed oil is in cross section substantially evenly circumferentially distributed around said head and maintained substantially coaxially extending from said spout.
The liquid dispensing package, suited for dispensing motor oil, comprising:
- a removable cap
- a bottle comprising top and bottom walls and a peripheral wall connecting said top and bottom walls and defining therewith a storage chamber, an outlet spout protruding from said top wall and removably carrying said cap, said bottom wall including a flexible push-in portion substantially aligned with said spout;
- a push rod in said bottle, said push rod having an elongate, generally longitudinally movable shaft extending between said push-in portion and spout, said push rod having a base which engages said push-in portion of said bottom wall, said push-in portion having storage and dispensing positions to which correspond storage and dispensing positions of said push rod, said push rod having a plug-like head fixed at the top portion of said shaft, said head having a storage position slidably disposed in said spout and a dispensing position spaced outward from said spout, said spout having an axially elongate, annular interior surface, said head having at least one, generally-circumferentially extending, flexible fin sealingly engaging said interior surface and forming therewith an axial liquid flow stop.
