UNITED STATES PATENT OFFICE.
THOMAS IV. FORSTER, OF DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF TO BUHL STAMPING COMPANY, OF DETROIT, MICHIGAN.
CAN-CLOSURE.
Specification of Letters Patent.
Patented Oct. 10, 1905.
Application filed December 20, 1902. Serial No- 185,953-
To (t/Z 'IIf/L OIIL it may concern.-
Be it known that I, THOMAS IV. F oRsTER, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan,
have invented a certain new and useful Improvement in Can-Closures; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to IO make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to can-closures, and has for its object an improved can-closure that 5 is especially adapted for use with milk-cans.
The serious objection that has been found in the use of milk-cans closed by cap-like structures with a cavity on the under side of the cap arises from the separation of the cream and the milk and the conversion of the cream into butter by the churning motion incident to the transportation of the can. One attempt that has been made to overcome the objection has introduced into the art the use of a wooden plug, which overcame this source of objection,
but introduced another objectionable feature incident to the character of the materlal em- 1 ployed for the closure, as a wooden plug cani not practically be kept clean, or so clean as requisite for use in milk-cans. The stopper or plug to be used must lit tightly to prevent the escape of the fluid and to prevent the introduction into the fluid of undesirable matter, especially such undesirable matter asrainwater, where the can is exposed to a rainstorm. The cover must also be easily and readily removable from the can, and there should be no projecting part, especially no part which projects upward in a way to prevent the stacking or piling up of empty cans on one another.
I. have devised a form which contains none of the objectionable features mentioned and which overcomes the difficulties incident to l l l l I can with which the plug is used and with the cup-bottom in close proximity to the surface of the liquid contained in the can, and there are no seams to be at any time in contact with the liquid where such seam may receive and retain portions of the liquid which becomes sour or tainted and from which the soured or tainted portions are with difficulty removed, or frequently notremoved at all.
The plug 1 has integral side and bottom walls 2 and 3. The upper rim of the cup is rolled or beaded over a strengthening-wire 4, and this strengthening-wire i is preferably provided with a loop 5, that is bent outward from the circle of the wire and is arranged to engage a chain or other holding means 6. In the top of the cup is inserted and secured closure 7. This closure is also preferably cupshaped but shallow, and the upper rim of the shallow cup which forms the closure is rolled or beaded over the roll which terminates the upper edge of the larger cup. The en tire plug is thus formed with a hollow or with an internal chamber entirely closed in and without seam or joint between the two parts which form the plug except the joint which-is at the extreme upper edge. The upper surface of the plug is sunk slightly below the extreme upper rim. To the upper surface of the sunken face of closure 7 is secured a rivet-plate 8 and a ring 9, by means of which the plug is easily withdrawn from the can K, but which when not in use for the purpose of withdrawal drops into the cavity above the plate '7 and presents no part that projects above the rim.
\V hat I claim isl. A closure for cans, comprising a deeplyconcaved part and a shallowly-concaved part, a rim-wire over which the walls of both parts are beaded, the said rim-wire being provided with a projecting loop, substantially as described.
2.. In a can-closure, in combination with a deeply-concaycd part to lit the can-neck, a shallowly-concaved part forming a closure to the top of the deeply-concaved part, means for securing the two together and a liftingring secured to the shallowly-concaved part and adapted to lie in the cavity thereof, substantially as described.
In testimony whereof I sign this specification in the presence of two witnesses.
THOMAS IV. FORSTER. Witnesses:
