Claims16
A combination flexible plastic closure and a container neck assembly in which said neck is of tubular form having intermediate its ends an inwardly directed flange terminating in an apical edge and having from said edge an axially outwardly flaring section with a frusto-conical internal surface defining a pour opening, said closure comprising a plug removably positioned in said pour opening and including a tubular flexible wall having an annular sealing ring projecting in closed position under said flange in fluid-tight engagement therewith and an external sealing ring on said tubular wall having an apical edge in fluid-tight engagement with said frusto-conical surface, combination guard and fulcrum means encompassing said neck assembly and in the closed position of said plug extending axially above the plug, and means for withdrawing the plug from said pour opening by fulcruming upon said combination means and tugging on said plug to release the same from said opening.
In an assembly of a plastic closure and a neck of a container, said neck having a radially outwardly projecting hook-like upper end portion defining a pour opening of a container;
- and said plastic closure having a closure portion insertable in fluid-tight fit into said container pour opening, and a separate but integral retainer portion sleeved over said neck and hooked under said hook-like portion, there being a hinge connection between said closure portion and said retainer portion for separate displacement of said closure portion relative to said neck.
A closure for a container having a wall with a neck member providing a pour opening;
- said closure comprising a flexible plastic plug having a seal-tight fit within said pour opening, a plastic guard member encompassing said neck member,
- a lift lever connected to said plug, and
- one of said members being formed to provide a combination pouring lip and fulcrum for fulcruming engagement by said lever upon lifting and tilting of said lever to thereby uncover said pour opening by lifting said plug out of said pour opening.
In a container, a neck, said neck being of a tubular form and having intermediate ends thereof a radially inwardly directed flange terminating in an apical edge, and a radially and axially flaring section extending from said apical edge, said section having a frustoconical inner surface defining a pour opening.
