CLOSURE FOR A CONTAINER Filed Feb. 12, 196B F/G Z United States Patent O U.S. Cl. 220--42 7 Claims ABSTRACT OF THE DISCLOSURE The invention disclosed herein provides an eiiicient structure of cap suitable for use on aerosol cans or `the like, which is especially suited for a vacuum forming operation of manufacture. The cap has provision for supporting it on the central part of an aerosol can adjacent the valve thereof that rigidly supports the cap. The cap is provided with means to make it tamperproof. The cap is formed of an inner generally cylindrical wall and an outer generally cylindrical wall concentric with the inner Wall. The outer wall and inner wall are rigidly connected together at the ends thereof remote from the open end of the cap.
It is, accordingly, an object of the invention to provide an improved aerosol can and cap.
Another object of the invention is to provide a cap for an aerosol can which is eicient to use yet is suitable for manufacture by vacuum forming.
Another object of the invention is to provide a cap for an aerosol can which is simple in construction, economical to manufacture and simple and efficient to use.
With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor `de- Itails of construction without departing from the spirit or sacrificing any of the advantages of the invention.
In the d-rawing:
FIG. 1 is a longitudinal cross sectional view of an aerosol can cap according to the invention.
FIG. 2 is a.- view of the cap shown in FIG. 1 having a closure on its end.
FIG. 3 is a broken away view of another embodiment of the invention similar to FIGS. 1 and 2.
FIGS. 4, 5, 6 and 7 show other embodiments of the invention similar in some ways to the views shown in FIGS. 1 and 2.
Now with more particular reference to the drawings, the cap 10 shown in FIGS. l and 2 has an outer cylindrical member 12 with a first end 13 and a second end 14. The inner cylindrical member 15 has a first end 16 and a second end 17. The disk-like end closure member 18 is supported on the annular member 19 which forms a closure with the outer and inner cylindrical members and is integrally attached to them. The second end of the cylindrical member 15 may be curled outwardly at 20 and the second end of the outer cylindrical member may be curled inwardly at 21. Thus, the inner cylindrical member can, at its second end, frictionally engage a rim 22 of an aerosol valve cup 23 and the outer cylindrical member 12 can frictionally engage an overhanging part of the can breast, such as a shoulder 24 on the breast 25 of the aerosol can.
The can cap shown in FIG. 3 has the outer cylindrical member 112 and the inner cylindrical member 115 similar to that shown in FIG. 1, however, the outer cylindrical member 112 has a groove 127 adjacent at its ii-rst end 113 ice and the closure 118 is formed downwardly into the groove 127. Otherwise, the cap shown in FIG. 3 is similar to the cap shown in FIGS. l and 2 wherein the inner cylindrical member terminates above a plane passing through the second end of the outer cylindrical member 112.
In the embodiment of the invention shown in FIG. 4, the outer cylindrical member 212 is attached to the inner cylindrical member 215 by means of an annular closure 219 and is integrally att-ached thereto. The closure 218 has its ends turned inwardly then downwardly at 230 and it frictionally engages the inner periphery of the inner cylindrical member 215.
In the embodiment of the invention shown in FIG. 5, the outer cylindrical member 312 is integrally attached to the inner generally cylindrical member 315 by means of the annular member 319. It will be noted that the cylindrical member 315 is actually formed specifically to a frustoconical shape. The groove 327 is formed in the second end 316 -of the inner cylindrical member and the disk-like closure 318 has its outer periphery disposed in the groove 319. The inner cylindrical member has its second end 317 curled outw-ard at 320, as shown, so that it may frictionally engage a portion of an aerosol cap above the outer periphery of the breast thereof.
In the embodiment of the invention shown in FIG. 6, the outer cylindrical member 412 is integrally attached to the inner cylindrical member 415 by means of the annular member 419. The second end 417 is turned inwardly at 420 to underlie the rim 422 of the aerosol can valve cup indicated. The outer rim 412 extends downwardly and may engage the outer periphery of the can in the same manner as the other embodiments of the invention.
In the embodiment of the invention shown in FIG. 7, the cap 512 has an outer cylindrical member 513 having its lower second end 514 stepped outwardly at 515 to overlie the rim 526 of the aerosol can 528. The outer cylindrical rim 427 is adapted to frictionally engage the outer periphery of the can.
The foregoing speciication sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
The embodiments of the invention in which an exclusive property or privilege is claimed are delined as follows:
1. A cap for use on an aerosol can comprising an outer generally cylindrical shell having a irst end and a second end,
an inner generally cylindrical shell having a first and a second end, said inner shell being disposed concentrioto said outer shell,
an annular closure member integrally attached to said inner member andintegrally attached to said outer cylindrical member and forming a closure at one end. of said cap between said outer and said inner shell, said second end of said outer closure member being curled inwardly and being adapted to underlie an overhanging portion of the breast of an aerosol can, said second end of said inner cylindrical member terminating inward of a plane passing through the said second end of said outer cylindrical member, said second end of said inner cylindrical member being adapted to frictionally engage a central part of an aerosol can adjacent the valve thereof and above the breast thereof.
2. The cap recited in claim 1 wherein said second end of said inner cylindrical member is curled outward.
3. The cap recited in claim 1 wherein said second end of said inner cylindrical member is disposed inward and adapted to underlie a rim of an aerosol valve cup above the breast of the can thereof.
4. The cap recited in claim 3 in combination with an aerosol can having a breast, a rim above said breast, and an enlarged part outward of said rim,
said inwardly disposed part of said second end of said second cylindrical member underlying said rim above said breast,
said second end of said first cylindrical member frictionally engaging said aerosol can.
5. The cap recited in claim 3 wherein said cap has a peripheral groove in said rst cylindrical member in said rst end thereof,
and a disk-like closure member is supported on said annular closure member,
the outer periphery of said disklike closure member being curled over said second end of said iirst cylindrical member and into said groove.
6, The cap recited in claim 3 wherein a groove is formed in said first end of said inner generally cylindrical member,
and a circular disk-shaped closure member has its outer periphery disposed in said groove.
