Safety cap for container

Claim 2

In a container having an upstanding circular neck defining its mouTh, a unitary closure cap including an end wall fitted over said mouth and seated against the end of said neck, said closure cap being rotatable with respect to the container, the improvement which includes a radially inwardly directed annular locking flange carried by the neck in said mouth, said flange being formed with a plurality of relatively spaced gaps extending axially therethrough, support means carried by the cap and extending into said mouth, and a plurality of locking lugs carried by said support means, said lugs projecting radially beneath said flange in axially abutting engagement therewith, and being positioned and proportioned for registry with a similar plurality of said gaps in a predetermined position of angular orientation of said cap on the container, whereby to permit application and removal of the cap to and from the container, said closure cap including a depending skirt encircling said neck, said neck and skirt respectively having cooperating radially projecting snap means for rotatably and releasibly securing the closure cap on the container in all positions of relative orientation of said closure cap and container.

Claim 3

In a container as defined in claim 1, the further improvement wherein said locking lugs are irregularly spaced from each other to register with similarly spaced gaps in the locking ring in but a single preselected position of orientation of said closure cap on the container.

Claim 4

In a container as defined in claim 1, the further improvement which includes cooperating external indicia on said closure cap and on the container, respectively, in positions for registry with each other when the closure cap and the container are in said predetermined position of angular orientation.

Claim 5

In a container as defined in claim 1, the further improvement wherein said cap includes a removal tab projecting radially from its said skirt at an angular location on the cap coincident with that of one of said locking lugs.

Claim 6

In a container having an upstanding neck of circular cross-section defining an upwardly opening circular mouth, a snap bead externally encircling said neck, and a closure cap having an end wall extending across said mouth and seated against the end of said neck and a depending skirt encircling said neck, said closure cap being rotatable on the neck, radially inwardly projecting retainer means within said skirt cooperating with said snap bead for releasably maintaining the closure cap snap-fitted onto the neck, the improvement which includes a radially inwardly directed annular locking flange carried within the neck adjacent the end thereof, there being a plurality of relatively circumferentially spaced gaps extending axially through said locking flange, support means depending from said cap through said flange and a plurality of locking lugs carried by said support means and projecting radially outwardly therefrom beneath said locking flange for engagement therewith to prevent removal of the closure cap from the container neck, said locking lugs being relatively angularly spaced and proportioned for simultaneous registry with a corresponding plurality of said gaps in a preselected rotational position of the closure cap on the container, to permit application and removal of the cap to and from the container.

Claim 7

In a container having an upstanding neck of circular cross-section defining an upwardly opening circular mouth, a snap bead externally encircling said neck, and a closure cap having an end wall extending across said mouth and seated against the end of said neck and a depending skirt encircling said neck, said closure cap being rotatable on the neck, radially inwardly projecting retainer means within said skirt cooperating with said snap bead for releasably maintaining the closure cap snap-fitted onto the neck, the improvement which includes a radially inwardly directed annular locking flange carried within the neck adjacent the end thereof, there being a plurality of relatively circumferentially spaced gaps extending axially through said locking flange, support means depending from said cap through said flange and a plurality of locking lugs carried by said support means and projecting radially outwardly therefrom beneath said locking flange for engagement therewith to prevent removal of the closure cap from the container neck, said locking lugs being relatively angularly spaced and proportioned for simultaneous registry with a corresponding plurality of said gaps in a preselected rotational position of the closure cap on the container, to permit application and removal of the cap to and from the container.

Claim 8

In a container as defined in claim 5, the further improvement wherein said support means is circular and concentric to the said flange to assist in centering the closure cap, and locking lugs with respect to the flange.

Claim 9

The invention defined in claim 6, further including indicia on the exterior of said cap and said container, respectively, for indicating when said closure cap is in said predetermined position of angular orientation on the container.

Claim 10

In a container having an upstanding circular neck defining its mouth, a unitary closure cap including an end wall fitted over said mouth and seated against the end of said neck, said closure cap being rotatable with respect to the container, the improveMent which includes a radially inwardly directed annular locking flange carried by the neck in said mouth, said flange being formed with a gap extending axially therethrough, support means carried by the cap and extending into said mouth, and a locking lug carried by said support means, said lug projecting radially beneath said flange for axial abutting engagement therewith, and being positioned and proportioned for registry with said gap in a predetermined position of angular orientation of said cap on the container, whereby to permit application and removal of the cap to and from the container, said closure cap including a pending skirt encircling said neck, said neck and skirt respectively having cooperating radially projecting snap means for rotatably and releasably securing the closure cap on the container in all positions of relative orientation of said closure cap and container.

Claim 11

In a container having an upstanding circular neck defining its mouth, a unitary closure cap including an end wall fitted over said mouth and seated against the end of said neck, said closure cap being rotatable with respect to the container, the improveMent which includes a radially inwardly directed annular locking flange carried by the neck in said mouth, said flange being formed with a gap extending axially therethrough, support means carried by the cap and extending into said mouth, and a locking lug carried by said support means, said lug projecting radially beneath said flange for axial abutting engagement therewith, and being positioned and proportioned for registry with said gap in a predetermined position of angular orientation of said cap on the container, whereby to permit application and removal of the cap to and from the container, said closure cap including a pending skirt encircling said neck, said neck and skirt respectively having cooperating radially projecting snap means for rotatably and releasably securing the closure cap on the container in all positions of relative orientation of said closure cap and container.
