BUNG FIXTURE FOR CONTAINERS AND SEAL THEREFOR Filed Oct. 50. 1929 INVENTOR.
ATTORNEY,
Patented Aug. 15, 1933 PATENT OFFICE BUNG FIXTURE FOR CONTAINERS AND SEAL THEREFOR .Irvin H. Riel re, Auburn, lnd., assignor to Rieke' Metal Products Corporation, a Corporation of Indiana Application October 30, 1929. Serial No. 403,518
Claims. -(Cl 220-39) This invention relates to improvements in a bung fixture for containers .and seal therefor, the object being to provide means for conveniently sealing the, bung opening of a container independently of the bung for closing the bung fixture whereby leakage of the contents of the container during shipment, and unauthorized withdrawal of the contents of the container are prevented.
Another object is to provide a bung fixture and a seal therefor that is easily applied so as to close the bung opening of the container which will remain in position upon removal of the bung from the bung opening.
These objects are accomplished by the construction illustrated in the accompanying drawing in which:
Fig. 1 is a vertical section showing a preferred embodiment of the invention;
Fig. 2 is a side elevation of the seal for the bung fixture, shown in its initial form before being applied to the fixture, a portion being in section; and
Fig. 3 is a bottom plan view projected from Fig. 2.
until arrested by having contact with the flange 8 which is of less internal diameter than the lower end of the wall 12 of the seal.
The seal is applied by inserting it endwise through the bung opening 4 of the container and into the ring 1, so that the lower end of the wall 12 rests upon the flange 8 of said ring. The bung 5 is then screwed into; the ring 1, whereupon the lower end 13 of the bung has forceful contact with the seal, causing the wall 12 thereof to become crushed outwardly into the groove 7 in the ring, so that the seal is thereby secured definitely in sealing position and the lower end of said ring thereby sealed.
,An advantage of the invention is that the container may be filled and the seal subsequently applied to close the bung aperture so that leakage of the contents of the container through the bung opening is prevented, and, upon removal of the bung, the seal remains intact and thereby indicates the genuineness of the contents shipped in the container.
The contents of the vessel may be withdrawn through the bung opening by first removing the bung and then dislodging or cutting away the The embodiment ofgthe invention shown in the j seal. The seal may be removed by applying drawing consists of an internally threaded bung ring 1 having at one end thereof a external flange 2 that is permanently secured in the folds of an embossment 3- made in a metal sheet 4 that forms the wall of a container. The embossment 3 surrounds the bung opening 4 made in the wall of the container and is closed by a bung 5 that extends through said opening and has threaded engagement with the ring 1, there being interposed between the head of the bung andf the top of the embossment a gasket 6 which is applied in the usual manner for eifecting a tight joint between the bung' and the wall of the container. The inner end of the ring 1 has an anular groove 7 and an interal flange 8 adjacent thereto beneath the groove, the inner perimeter of the flange 8 being of less diameter than that of the threaded portion 9 of the ring. The seal 10 is in the form of a shallow inverted cup, the closed end of the cup forming a diaphragm 11, the outer wall 12 of the cup being contiguous with the diaphragm and slightly inturned around its free end. The seal 10 is made of a single piece of thin sheet metal of ductile characteristics so-that its peripheral wall becomes expanded upon pressure being applied endwise to the cup about its margin. The seal is so proportioned as to admit of its insertion freely through the threaded portion of the ring ,force with a suitable instrument, such as a hammer. By striking the diaphragm with the hammer applied through the bung opening, the seal becomes dislodged from the groove and leaves the bung opening free. Or, the diaphragm may be cut away by applying any suitable sharp instrument thereto.
A container provided with the bung fixture herein disclosed may be refilled and sealed repeatedly by applyinga new seal upon each filling, the invention being useful in the prevention of fraudulence by the substitution of spurious goods for that with which the container is filled at the point of shipment.
I claim:
1. In an appliance of the class described, the combination with a container provided with a bung opening, of a bung ring secured in the wall of the container concentric with the opening therein, said ring-being internally threaded and having an internal flange at its inner end of less diameter than that of its threaded portion, and having an internal groove adjacent said flange, a seal in the form of a cup, the peripheral wall of which is slightly inturned at its free end, the diameter of said peripheral wall beinginitially less than that of the threaded portion of said ring and greater than that of said internal flange, so that said seal maybe ing of the container and seated upon said flange, and a bung insertable into the outer end of said ring for closing said bung opening, adopted to compress said seal so that the peripheral wall thereof is crushed and thereby extended into said internal groove in the ring to secure the seal in place.
2. A sealing means for the bung opening of a container, consisting of an internal threaded bung ring extending into the container and secured to the wall thereof concentric with said bung opening, said ring having an internal flange at its inner end and a groove contiguous therewith, an inturned seal consisting of a diaphragm provided with a peripheral wall of less diameter than that of the threaded portion of said ring so that said seal may be inserted through said bung opening into said ring with theiree end of its said wall seated upon said flange, and a.bung insertable into said ring for closing said bung opening, which bung, when so inserted compresses said wall against said flange and causes it to become-extended into said groove and the seal thereby secured in P1808.
3. A sealing means for the bung opening of a container, consisting of an internally threaded bung ring secured to the wall of a container concentric with the bung opening therein, and
, 1,928,026 inserted into said ring through the bung openprovided with an internal flange at its lower end and a groove contiguous therewith, a seal having an inturned peripheral wall and insertable into the ring so its wall is seated upon and compressed against. said flange and extended into said groove by a hung upon insertion thereof into said ring against the seal.
4. A bung ring for a container in combination with a seal for closing one end thereof, said ring being internally threaded and provided. with an internal flange at one end and a groove contiguous therewith, said seal having an inturned peripheral wall adapted to be seated at its free end on said flange and compressed by a bung when said bung is inserted into the ring whereby said seal is extended into said groove and secured in place.
5. A container having a bung opening and a bung ring disposed concentrically with said opening, said ring being provided at one end thereof with an annularv groove and internal flange contiguous therewith, and a seal consisting of a diaphragm provided with a peripheral wall enga'geable at its free end by said flange upon insertion of the seal into the ring, said wall being so formed as to become extended into said groove upon pressure being applied to the top of the seal by a bung inserted into said ring.
