Description

UNITED STATES PATENT OEEICE.
MAX AMS, OF NEW YORK, N. Y.
COVER FOR SHEET-METAL CANS.
SPECIFICATION forming part of Letters Patent No. 581,257, dated April 27, 189'7. Application filed December 11,1896. Serial No. 615,381. (No model.)
To all whom it may concern:
Be it known that I, WAX AMS, of New York city, county and State of New York, have invented an Improved Cover for Sheet-Metal Cans, of which the following is a specification.
This invention relates to a head or cover for sheet-metal cans, and more particularly to novel means for permitting such head or cover to be quickly opened.
In the accompanying drawings, Figure l is a side View, partly in section, of the upper part of a sheet-metal can provided with my improved cover. Fig. 2 is a longitudinal section throughthe cover before being upset. Fig. 3 is a plan of the cover, showing it closed; Fig. 4, a plan of Ithe cover, showing it partly opened.
The letter a represents a sheet-metal packing-can of the usual or suitable construction.
b is the cover or head, which is composed of a countersunk central portion b', an upright neck or wall b2, and a laterally-extendin g flange b3, which is adapted to be connected to the fiange a of can a by a lap-joint, Fig. l. The central or countersunk portion of cover b is provided with two indented or weakened concentric circles c c,that form between them the ring c2. The outer circle c should be formed close to the neck b2, so that when the can is opened no objectionable raw edge or fin is left standing around such neck.
Through a transverse slit c3, cut across annular section c2, there is introduced one end of a sheet-metal tongue d, Which projects partly into and partly out of the cover. The
inner or concealed end of this tongue is soldered to the inner side of the ring c2, while the outer or protruding end of the tongue remains disconnected from the ring and is placed at upon the same.
Vhen the cover is to be opened, the exposed endv of the tongue d is grasped by a key in the usual manner, and thus the ring c2 is gradually coiled up and torn out, Fig. 4, to remove or partly detach the countersunk section ofthe cover.
It will be seen that by countersinkin g the indented portion of the cover and also the tongue beneath the chime of the can-body these parts are effectively protected against injury and against accidental opening. The advantages connected with my improved cover are that it requires but little material, forms a perfect joint, and can be readily opened.
A can-cover having a vertical neck or wall, a laterally-extending flan ge which forms a lapjoint with the top edge of the can; and provided' with two indented or weakened concentric circles that form a ring between them, the outer circle being formed at the base of the vertical neck or wall; combined with the can, having a flange at its top over which the flange on the cover forms a lap-joint and a tongue secured to one end of the ring through a cut therein, the tongue being protected by the chime of the can-body, substantially as shown.
MAX AMS.
