Security caps for containers

Claim 2

A cap for an aerosol container having a bead around its top outer periphery comprising a hollow cap including a bottom skirt depending from a superimposed body portion, a plurality of inwardly-extending spaced lugs on said skirt for engaging the bead on said container one of said lugs being disposed at the front of said cap, the lower portion of the front wall of said cap above said front lug having one or more vertical stiffening ribs extending upwardly from said skirt to a point spaced downwardly from the top of the cap, said ribs being on the outside of said front wall, the upper portion of said cap above said stiffer portion being more flexible than said stiffer portion and adapted to be deformed when inward pressure is exerted against said upper portion to distort said skirt to move said front lug radially outwardly, said cap being removable backwardly and upwardly off said container after said front lug has been so moved outwardly, followed by exertion of upward pressure on said front wall to raise said front lug free and clear of said container bead.

Claim 3

A cap for an aerosol container having a bead around its top outer periphery comprising a hollow cap including a bottom skirt depending from a superimposed body portion, a plurality of inwardly-extending spaced lugs on said skirt for engaging the bead on said container one of said lugs being disposed at the front of said cap, the lower portion of the front of said cap above said front lug being stiffer than the remainder of said body portion, the upper portion of said cap above said stiffer portion being more flexible than said stiffer portion and adapted to be deformed when inward pressure is exerted against said upper portion to distort said skirt to move said front lug radially outwardly, the cap having a back cylindrical portion which merges forwardly into a flat transverse front wall, the flat transverse front wall being inclined, said cap being removable backwardly and upwardly off said container after said front lug has been so moved outwardly, followed by exertion of upward pressure on said front wall to raise said front lug free and clear of said container bead.

Claim 4

A cap for an aerosol container having a bead around its top outer periphery comprising a hollow cap including a bottom skirt depending from a superimposed body portion, a plurality of inwardly-extending spaced lugs on said skirt for engaging the bead on said container one of said lugs being disposed at the front of said cap, the lower portion of the front of said cap above said front lug being stiffer than the remainder of said body portion, the upper portion of said cap above said stiffer portion being more flexible than said stiffer portion and adapted to be deformed when inward pressure is exerted against said upper portion to distort said skirt to move said front lug radially outwardly, the cap having a back cylindrical portion which merges forwardly into a flat transverse front wall, the flat transverse front wall being inclined, said cap being removable backwardly and upwardly off said container after said front lug has been so moved outwardly, followed by exertion of upward pressure on said front wall to raise said front lug free and clear of said container bead.

Claim 5

A cap as claimed in claim 2 where the inside surface of said flat front wall bears against a curved cover of one of said containers so that when pressure is exerted against the upper portion of said front inclined wall, the lower portion of the front wall is cammed outwardly to move the front lug radially outwardly.

Claim 6

A cap for an aerosol container having a bead around its top outer periphery and an upstanding inner crown-shaped cover comprising a hollow cup-shaped cap including a bottom skirt depending from a superimposed body having a cylindrical back portion of relatively smaller radius than that of said skirt merging forwardly into an inclined flat transverse wall, the inside surface of said wall being adapted to bear against the curved cover on said container, a plurality of inwardly-extending spaced lugs on said skirt for engaging the bead on said container, a first lug being disposed below said flat wall, said flat wall being adapted to be flexedly cammed about the surface of said container crown when inward pressure is exerted against said wall above the point of contact of said wall with said crown to distort said skirt to move said first lug radially outwardly, and said cap being removable backwardly off said container, after said first lug has been so moved outwardly, followed by exertion of upward pressure on said flat wall to raise said first lug free and clear of said container bead.

Claim 7

A cap for an aerosol container having a bead around its top outer periphery and an upstanding inner crown-shaped cover comprising a hollow cup-shaped cap including a bottom skirt depending from a superimposed body having a cylindrical back portion of relatively smaller radius than that of said skirt merging forwardly into an inclined flat transverse wall, the inside surface of said wall being adapted to bear against the curved cover on said container, a plurality of inwardly-extending spaced lugs on said skirt for engaging the bead on said container, a first lug being disposed below said flat wall, said flat wall being adapted to be flexedly cammed about the surface of said container crown when inward pressure is exerted against said wall above the point of contact of said wall with said crown to distort said skirt to move said first lug radially outwardly, and said cap being removable backwardly off said container, after said first lug has been so moved outwardly, followed by exertion of upward pressure on said flat wall to raise said first lug free and clear of said container bead.

Claim 8

A cap as claimed in claim 4 having at its back an inner depending flange which forms with said skirt a channel whose sides straddle the bead on said container and acts to prevent backward motion of said cap off said container until the front of the cap is raised upwardly off the container.

Claim 9

A cap as claimed in claim 4 wherein there are first and second such flat walls in the front portion of said body, said first lug disposed below said first wall, a second lug being disposed below said second wall.

Claim 10

A cap as claimed in claim 6 wherein said first and second walls lie in planes which intersect in approximately a right angle.

Claim 11

A cap as claimed in claim 4 wherein the lower edge of said skirt is recessed between adjacent lugs.

Claim 12

A cap as claimed in claim 8 wherein each recess is arcuate.

Claim 13

A cap as claimed in claim 4 wherein each said lug is integral with a boss on the inside surface of said skirt, said bosses defining a reference circle having a diameter approximately 0.1 inch less than the inner diameter of said skirt, whereby a range of container bead diameters may be accomodated.
