CONTAINER Filed March 5, 1935 ORNEYS Patented May 5, I936 UNITE srArEs PATENT OFFICE 3 Claims.

This invention relates to containers, and its general object is to provide a closure for a container such as a metallic barrel or the like, that can be easily and expeditiously applied and removed with respect to the container, yet casual removal or displacement is impossible and a leak proof connection is assured.

Another object of the invention is to provide a closure for a barrel or the like, that forms the head thereof, and which includes a split resilient ring member normally expanded for holding the closure in sealed position, with means for contracting the ring member to allow the removal of the closure.

Another object of the invention is to provide a closure of the character set forth, that includes means for holding and locking the ring member in contracted or expanded positions, and the container end is sodesigned to bear against the ring member when the latter is in operative position to set up a. clamping action. a

A still further object of the invention is to provide a closure that is simple in construction, inexpensive to manufacture, and extremely efllcient in use and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a top plan view showing my closure applied to a container with the ring member thereof contracted or in unsealed position and held and locked accordingly.

Figure 2 is a similar view showing the ring member expanded.

Figure 3 is a sectional view taken approximately on line 33 of Figure 2, looking in the direction of the arrows.

Figure 4 is a sectional view taken approximately on line fi-t of Figure 1, looking in the direction of the arrows.

Figure 5 is a perspective view of the handle for contracting and expanding the ring member.

Referring to the drawing in detail, the reference numeral l indicates a container which as shown is in the form of a metallic barrel, but I want it understood that my closure can be utilized with any type of container that can be adapted therefor. The upper end of the container is outwardly bulged in rounded formation as at 2 to provide an annular channelv 3 and the outwardly bulged portion terminates at its upper end in a reinforced bead 4. The upper wall of the channel is curved upwardly and inwardly and terminates in the bead outwardly of the lower wall which is slightly upwardly inclined and provides a seat 5.

The cap of my closure includes a disk like body 6 that has formed with the periphery thereof an upwardly directed flange I which in turn has formed therewith an outwardly inclined crimped flange 8 received by the seat 5, but disposed between the flange 8 and the seat 5 is a gasket 9, so as to provide a leak proof connection between the cap and the container, as will be apparent.

The essential feature of my closure lies in the resilient or expansion ring I!) which as best shown in Figure 3 is provided with beveled side faces and an inwardly and downwardly inclined bottom face and a slightly curved downwardly and outwardly inclined upper face.

The ring is transversely split as at I l and formed on one end thereof is an inwardly curved arm l2, the latter increasing in width toward its free end and has arranged therein a slot l3. Ex-- tending inwardly from the ring and diagonally with respect to each other are apertured ears I4 and I5, each of which has formed thereon an upstanding lug I6. An ear I I is likewise formed with the ring l0 and extends inwardly thereof,

and has pivotally secured thereto one end of a lever I8 which is of alength to be received by either of the apertured ears l4 and I5 and has an opening in its free end for registration with the apertures of the last mentioned ears for a purpose which will be presently described. The lever is also provided with an opening adjacent its pivoted end for the purpose of receiving a pivot pin 19 that is mounted in the slot l3 of the arm l2.

It will be noted from the drawing that the expansion ring increases in width from its split ends and gradually tapers so that its greatest width or thickness is diametrically opposite the split. That feature retains the ring in substantially true circular formation at all times to assure proper sealing action and easy removal and application with respect to the container. The end portions of the ring are beveled as shown for a sliding fitting engagement with each other.

The lever l8 may have formed thereon or otherwise secured thereto a collar member 20 of rectangular configuration for the purpose of receiving an extension lever not shown, for increasing the leverage for expanding and contracting the expansion ring, as will be apparent.

The cap is preferably provided with a handle 2| of the bail type and which is secured to the body thereof by a flanged barrel member 22.

From the above description and disclosure of the drawing, it will be obvious that I have provided a closure for metallic barrels and the like, that can be easily and expeditiously applied and removed with respect to the barrel, and'when appliedthereto, in sealed position, a leak proof connection is assured. However, it might be stated that the, cap is disposed within the channel and against the gasket 9. The ring is then arranged. in the channel to bear against the crimped flange 8, with its curved upper face disposed for engagement with the upper wall of the channel. It will of course be understood that the ring is in its contracted condition when applying it within the channel and is held accordingly by the lever l8 having its free end received by the lug of the apertured ear M, as shown in Figure 1. After the expansion ring is so disposed, the free end of the lever I,8 is removed from the'lug of the ear I4 and disposed on the ear l5 to contact the lug I6 thereof, as shown in Figure 2. This action allows the ring to expand or be expanded against the crimped flange 8 and .the upper wall of the channel, the latter setting up a resilient action against the upper face of the ring, which is curved as above set forth in order to fit the upper wall and as clearly shown in Figure 3.

The lever may be locked ineither of its positions, through the instrumentality of a padlock 23.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
