TATE PATNT JOHN E. DOLDT, OF PORTLAND, MAINE, ASSIGNOR T0 STAR SEAL COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW' YORK.

SEALING DEVICE.

Application filed February 1, 1913.

To all whom it may concern:

Be it known that 1, JOHN E. Donor, a citizen of the United States, residing at Portland, county of Cumberland, State of Maine, have invented certain new and useful Improvements in Sealing Devices, of which the following is a specification.

This invention relates to sealing or protecting devices, and particularly to a bung seal or protector to be used on barrels, kegs, casks and analogous liquid containing receptacles.

For a long time there has been a demand among manufacturers and distillers for a bung seal which could be applied to the receptacle so as to make impossible access to the contents thereof without mutilating or destroying the seal, thereby preventing fraudulent tampering with the container. These manufacturers and distillers usually desire to place upon the receptacle containing their goods, an assurance or guaranty that the contents of the receptacle are genuine and have not been tampered with since leaving their plants.

To this end I have devised my present invention in which I employ an annular ring attached to the receptacle and a flexible diaphragm adapted to be applied over the bung of the receptacle and expanded under the ring, the seal thus provided effectually preventing access to the contents of the receptacle without mutilating or destroying the diaphragm. The receptacle when thus sealed is incapable of being refilled without giving evidence of having been tampered with, thereby assuring the user that the contents are the original and genuine product.

The construction and operation of my device will be more fully disclosed in the specification which follows, and as illustrative of my invention I have shown in the accompanying drawings an embodiment which I have found practical and well adapted for commercial purposes.

Throughout specification and drawings similar characters of reference are employed to denote corresponding parts, and in these drawings Figure 1 is a sectional view through that part of a containing receptacle adjacent the bung hole illustrating the position of my seal with reference to the bung hole.

Specification of Letters Patent.

Patented July MD, 1917.

Serial No. 745,593.

Fig. 2 is a similar View showing the hung in the bung hole and the bung seal fastened down upon the bung.

Fig. 3 is a plan view, and

Fig. 4 is an enlarged fragmentary section illustrating the position of the diaphragm when it has been forced down upon the bung and engaged beneath the ring on the receptacle.

I have indicated at 5 that portion of a containing receptacle in which the bung is mounted. This part has a hung hole (3 in which is seated a suitable bung 7 The portion 5 is counter-bored slightly so as to provide an annular recess 8 which may be, as shown in the drawings, in the shape of a V. This recess surrounds the bung hole externally but has no connection therewith. A flat annular ring 9 is attached to the container by any suitable fastenings 10 and has an annular opening concentric with, but of slightly greater diameter than the bung hole.

The bung seal proper consists of a flexible diaphragm 11 depressed around its edge as at 12 to provide an upturned flange 13 of substantially the shape of the annular recess 8 of the container.

The advantage gained by cutting the recess 8 in the shape of a V is important. This counter-bore is V-shaped in order not to cut away the length of the bung hole. The thickness of the board is therefore only reduced by such an amount as will enable the ring to have a flat lodgment around the outer edge of the bung hole, the seal being so shaped as to accommodate the bung and so applied as not to reduce the length of the bung hole. When it is considered that such devices as are commonly used have the effect of driving down the bung and thereby shortening the length of the bung hole, the advantage of the present invention is apparent as affording a construction which will not drive the bung too deeply when the seal is set, or shorten up the length of the bung hole.

In use, the bung is inserted in the bung hole and the diaphragm placed on the bung and its edge forced down into the recess of the container by any suitable expanding tool. This causes the upturned flange 13 to bear against the under face of the ring 9, as best shown in Fig. 4t. The bung is now sealed and unauthorized access to the contents of the receptacle can not be had Without mutilating the diaphragm.

The depressed portion 12 may be made to coincide exactly with the corresponding face of the annular recess 8 or may be set at a sharper angle so as to be tilted when the seal is set, thus forcing the upturned flange 13 more firmly against the lower face of the ring 9.

Various modifications in the construction and operation of my invention may obviously be resorted to if Within the limits of the appended claims.

That I therefore claim, and desire to secure by Letters Patentis:

1. In combination with a container having an opening therein and having an adjacent recess, a member secured to the surface of said container and slightly overlying said recess therein, and a sealing member covering said opening of the container so as not to materially reduce the effective length thereof and comprising a depressed portion so disposed as to be tilted when the seal is set and a portion adapted to be forced against one face of the rigid member by the tilting of the depressed portion.

2. In combination With a container having an opening therein and having an annular recess, a member secured to said container and partially overlying said annular recess therein and a second member covering said opening of the container and disposed so as not to materially reduce the effective length thereof and depressed about its edge to fit said recess and to provide a flange to bear against the under face of said first named member.

3. In combination With a container hav- JOHN: noLnr; IVitnesses:
