UNITARY MOLDED RESILIENT PLASTIC CAP Filed Feb. 16, 1968 INVENTOR MANNIE LA BARBERA BY @Wf? ATTORNEYS.

United States Patent 3,450,299 UNITARY MOLDED RESILIENT PLASTIC CAP Mannie La Barbera, Armonk, N.Y. (160 Hunts Lane, Chappaqua, N.Y. 10514) Filed Feb. 16, 1968, Ser. No. 706,134 Int. Cl. B65d 41/16, 41/62, 51/18 US. Cl. 22042 1 Claim ABSTRACT OF THE DISCLOSURE This invention relates to container caps and more particularly to a cap for a container adapted to hold a liquid under pressure.

It is common practice to provide containers with liquid under pressure with caps to cover their valves so as to produce an improved appearance. Such containers vary in size, especially the valve housing thereof resulting in damage to the caps when applied if they do not fit properly.

A primary object of the instant invention therefor is to provide a cap which will allow for a wide variation in manufacturing dimensions without danger of damage to the cap.

Another object of the invention is to provide a cap of simple form which may be produced in quantity economically, which will fit a container snugly even when there are variations in the size of, for example, the valve housing, and which will enable the containers to be stacked one on top of each other, without any danger of the valve being inadvertently actuated.

FIGURE 1 is a spread perspective view of a container with a cap made in accordance with the present invention shown removed in solid lines and shown in position in dash lines.

FIG. 2 is a side elevational view of the container showing the cap in position, the cap being shown sectioned.

FIG. 3 is a cross-sectional view taken on the plane of the line 33 of FIG. 2.

FIG. 4 is a top perspective view of the improved cap, parts being shown broken away, on an enlarged scale.

FIG. 5 is a top perspective view of the improved cap, parts being shown broken away.

Referring now in detail to the various views of the drawings, a cap made in accordance with the instant invention is shown in FIG. 1 and designated generally at 10. In FIG. 2, the cap is shown applied to a container 12 for perfume under pressure equipped with a valve operator 14 and a ferrule 16. The cylindrical body of the cap has a side wall 18 and a top wall 20 as viewed in FIGS. 1 and 2, and is open at the bottom. The cap seats on the top edge 22 of the body of the container.

In accordance with the invention and as best seen in FIG. 4, the cap is provided with a number of vanes 24,

7 3,450,299 Patented June 17, 1969 three being shown. The vanes are perimetrically or circumferentially equally spaced with respect to the axial or side wall 18 and are formed integrally with the inner surface of said wall and with the inner surface of the top wall. The body of each vane is formed integral with the inner surface of the side wall and for the length of the vane, and its top edge 24 is integral with the inner surface of the top wall. The free long edge of each vane is formed with a head 26. In accordance with the invention, the bodies of the vanes are disposed tangentially to the surface of the side wall rather than radially thereof. The bottom ends 28 of the beads curve slightly outwardly to facilitate passage over the valve operator 14. The beaded free long edges of the vane are parallel to the inner surface of the side wall 18 so that each vane will be flexible so as to yield when applied to the ferrule 16 without imposing undue stresses to the Wall of the cap itself. The bottom ends of the vanes are slightly curved outwardly to facilitate application of the cap to the container for which it is intended.

The caps 10 in accordance with the instant invention are preferably unitary molded resilient plastic bodies having vanes whose radial dimensions are small enough to assure flexibility in an outwardly direction consistent with frictional engagement with the container sufiicient to avoid accidental dislodgement.

It will be understood of course that the edge at the open end of the cap need not seat on the top edge 22 of the body of the container 12 but may seat on the shoulder 30 of the body of the container 12.

While I have illustrated and described the preferred embodiments of my inventions it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.

What is claimed is:

1. A unitary molded resilient plastic cap comprising a cylindrical body with a side wall and a top wall and being open at the bottom, for application to a container, a plurality of perimetrically spaced elongated vanes each having one long edge integral with the inner surface of the side Wall, for the entire length of said edge, and with one end edge integral with the top wall, each vane having a free long edge resiliently engageable with a portion of a container, whereby said vanes are yieldable to relieve said walls of stresses during application and removal of said cap relative to a container, the bodies of the vanes being arranged tangentially of the inner surface of the side wall and beads along the free long edges of the vanes, the bottom ends of the beads being curved outwardly to facilitate application of the cap to a container.
