Child resistant aerosol can cover
View Patent ↗A child resistant detachable molded plastic cover member for a cylindrical aerosol can is provided having improved release and storage capability. The cover employs an unperforated outer shell having physical depressions suitably placed on the outer surface to release the cover member.
1. A child resistant cylindrical aerosol can cover formed with a flexible molded one piece polymer member having an unperforated outer hollow shell enclosing a hollow inner shell which are always and continuously physically interconnected together with single diametrically opposed radially extending rib elements, said cover member further having release means consisting essentially of physical depressions disposed on the exterior surface of the outer shell which physically engage the outer end of each rib element.
2. The cover member of claim 1 having a cylindrical cup shape formed with top and side wall surfaces terminating in an open bottom.
3. The cover member of claim 1 wherein engagement of each depression with the outer end of each rib element occurs approximately at the midpoint of said depression.
4. The cover member of claim 2 wherein said depressions extend from the top wall surface of said cover member and have a curved shape.
5. The cover member of claim 4 wherein said depressions are convex in shape.
6. The cover member of claim 2 wherein the inner shell of said cover member further includes inwardly projecting bottom detent elements for locking engagement of said cover member to a cylindrical shaped aerosol can.
7. The cover member of claim 1 wherein said cover member is formed with a synthetic thermoplastic polymer material.
8. A pressurized aerosol can having a cylindrical shape with a centrally disposed valve means at one end enabling detachable physical engagement thereat of a replaceable cylindrical flexible molded plastic cover member, the cover member having a cup shape formed with top and side wall surfaces terminating in an open bottom to include an unperforated outer hollow cylindrical shell enclosing an inner hollow cylindrical shell surrounding the dispensing valve means and with said inner hollow shell further including inwardly projecting bottom detent elements for locking engagement of said cover member to said can member, said cover member further having release means consisting essentially of physical depressions disposed on the outer shell of said cover member while being always and continuously physically interconnected to the inner shell of said cover member with single radially extending rib elements.
9. The cover member of claim 8 wherein
the inner hollow shell further includes outwardly extending protuberances physically connecting the inner ends of both single rib elements to said inner shell.
