BY ibm ATTORNEYS.

Patented June 25, 1935 UNITED STATES PATENT OFFICEI 9 Claims.

. This invention relates to a closure for a container for liquids, pa'stes and the like, and is an improvement over the closure disclosed in the copending application led by me jointly with Benjamin?. Remy on January 14, 1933, Serial No. 651,776, entitled Closure for containers.

The object of the invention, and as set forth in the above-mentionedapplication, is to provide a sealed closure which is fluid-tight when closed, 1o and which may be conveniently opened and closed by a slight turning movement of the cap without removing any part thereof from the container. Furthermore, it embodies a non-removable cap which when in one position closes and seals the nozzle of the container, and while. in the other position is retracted to permit the nozzle to protrude therethrough so that the cap will not become fouled by the contents of the container when discharged.

The present invention resides in the structural features of the closure, wherein it is simple in design, compact, sturdy and cheap to manufacture in quantity production.A It will be appreciated that in closures of this type three essential features are involved to make it commercially practical and of benefit -to the public.

Firstly, the closure must be compact and conveniently small so as not to loom bulkily over the container, particularly wherein the public is accustomed to comparatively small closures. This is accomplished by permitting the sealing valve to move downwardly to one side between the cap and nozzle rather than be swung laterally so as to require substantial space between the cap and nozzle.

Secondly, it is essential that the structure be rugged and fool-proof since the constant operation thereof in opening and closing the container should not affect its working parts to such a degree as may destroy its usefulness and thereby the usefulness of the container before it is emptied of the contents.

Thirdly, and perhaps most important, the closure must be so designed as to permit of very cheap quantity production. In many instances the containers themselves are produced for only a few cents and the usual closures therefor for small fractions of a cent. Therefore, for commercial purposes, and to obtain any'practical benefit to the public, a closure of this character must be produced within a reasonable. margin of the cost of the container and the usual type of cap or closure.

The full nature of the invention will be un derstood from the accompanying drawing and the following description and claims:

In the drawing, Fig. 1 is a top plan view of the closure mounted on the end of a collapsible tube. Fig. 2 is an enlarged view showing the 5 left half of the upper end of the tube and nozzle in central vertical section with the right half in elevation. Fig. 3 is an enlarged view showing the closure mounted on the tube and nozzle in open or discharging position. Fig. 4 is the same as Fig. 3 showing the closure in closed position. Fig. 5 is a section taken on the line 5-5 of Fig. 4.

In the drawing there is illustrated a collapsible tube I0 having its lower end spread out as indicated at II to provide a permanent bottom closure. The upper end of the tube is formed with a neck I2 and a discharge nozzle I3, the nozzle being surrounded by an annular cup I4 about which the closure is secured. The closure comprises a cap I5 having a knurled side wall indicated at I6, and a central aperture in the top indicated at I1 through which the nozzle I3 is adapted to protrude when in open position, as illustrated in Fig. 3.

Frictionally secured within the cap I5 there is a compressible band I8 having split ends, as indicated at I9 in Fig. 5, to permit the band to be compressed within the cap I5 and expand therein to secure the structure in position. Said band is provided on opposite sides thereof with inwardly extending bosses 20 adapted to extend through a cam-like slot 2I formed aboutr the opposite side walls of a collar 22. The collar 22 is formed about its lower edge with a series of teeth 23 adapted to surround the cup I4 and extend into a groove 24 thereof to be crimped and secured thereabout for locking the closure on the container. Said collar is provided with freeiends, as indicated at 22a, for permitting it to be compressed within the compressible band I8.

Mounted within the collar 22 and pivotally supported upon the bosses 20 there is a valve cap 25 provided with a cork insert 26, said valve cap being concave to extend over the open end of the nozzle I3 for sealing the same. The cap terminates in a pair of downwardly curved arms 21 through which the bosses 2D extend toA provide the pivotal support for the valve. Each of said arms is provided with a"cut away portion providing shoulders 28 adapted to be engaged in the actuation of the closure by the inwardly provjecting lugs 29 for manipulating the valve, as hereinafter described.

In operation, assuming that the closure is in the container is held xedly with one hand, while the foreiinger and thumb are placed about the knurled surface of the cap l5, which is thereby turned counterclockwise to open the closure. In thus turning the cap, the collar remaining stationary, the bosses 20, extending from the cap through the slots 2| in the collar, are carried throughout the length of their respective cam slots 2| in the stationary collar. As will be noted in Fig. 4, the first counterclockwise movement carries the bosses upwardly in the initial upwardly extending portions of the slots 2| which acts to lift the cap and valve free of the nozzle. Continued counterclockwise movement carries the bosses through the laterally-extending portions of the slots 2|, to a. position where the lugs 29 are within the recess of the shoulders 28 formed in the arms of the valve. Continued movement causes the shoulders 28 to engage the lugs 29, wherebyfurther relative movement between the shoulders 28 and lugs 29 act to swing the valve cap 25 about the pivotal mounting of the lugs to the position shown in Fig. 3. Further counterclockwise movement causes the bosses 20 to travel through the downwardly-extending portion of the cam slots 2| to lower the cap and permit the uncovered end of the nozzle to protrude through the aperture I1 to permit free discharge of the contents without fouling the closure.

By a clockwise rotation, the reverse action takes place, the cap travelling upwardly until the top thereof extends overthe top of the nozzle,

whereupon the lugs 29 are engaged by the oppo-y site shoulders 28 to swing the cap 25 upwardly over the end of the nozzle. Continued clockwise movement causes the bosses to pass through the downwardly-extending portion of their respective cam slots to cause the valve cap to be drawn tightly over the nozzle so that the cork gasket 26 is held in sealed engagement therewith.

The invention claimed is:

1. In a container having a nozzle protruding therefrom, a closure therefor comprising an apertured cap through which said nozzle is adapted to extend when said closure is in open position, a fixed collar secured about said nozzle provided with cam slots therein, bosses associated with said cap extending through said cam slots to permit rotation of said cap on said collar, a valve pivotally mounted on said bosses within said collar, and means for swinging said valve about its pivotal mounting to open and closed position relative to said nozzle upon rotation of the cap.
