As the upper edge of the can-bod y will give or bend inward when engaged by the hey, l lind by actual experirnent that the can-body lying' inside the cover- B' at the hey-insertion groove 7)" does not prevent the easy insertion of the key through the cover-flange. This result is also due to the fact that the cover-flange B is only soldered to the can-body at its lower Zone or portion 7;, thus leaving the upper edge of the can-body free to yield inward when the hey is inserted.

rEhe key D is made of steel wire and has an integral loop-handle D', asharp point (Z2, and cutting edge (Z3, preferably slightly inclined, as shown, and a longitudinal slot d'1, forming the forks d (Z' to tit astride the tearing-strip 7) at the slot 7), so that by turning the key the tearing-strip will irst part along the transverse score or weakened line and then wind in the usual manner about the key. After the can has been opened by removing the tearing-strip the soldering zone or band of the deep iiange E of the cover forms a shoulder or stop for the slip-cover iange /T of the cover B. rihe upper end a of the can-body A., which lits within the flange Bf of the cover B, acts as a niandrei or support for the cover-fiange B in winding the tearing-strip about the key and causes the can to open with ease and certainty and prevents danger of the tearing-strip running out and failure of the can to open properly.

By iny invention the labor and expense 'of soldering separate tongues to the tearing-strip and also the 'uncertainty and failure of opening incident to the use of separate -piece tongues on the tearing-strip are entirely avoided and a inuch cheaper and better can produced. I

if claiml. The tongueless-tearing-strip key-opening paint-can herein shown and described, and comprising a can-bod y and a deep iiange-cover soidered to the bot at the lower riin or Zone of said deep iiange, the deep iange of the cover being provided with an endless and tongueless tearing-strip having' parallei scores or weakened lines, a score or weakened line extending transversely 'across the tearingstrip, and a key-insertion groove parallel to the tearing-strip adjacent to said transverse score or weakened line, said deep flange of the cover having a slip-cover flange riin or Zone above the tearing-strip for closing the can after it has been opened, the upper end of the can-body projecting within said cover-delige adjacent to said key-insertion groove there'n, so that a sharp or chisel pointed key can be inserted through said groove preliminary to opening the can to form a bend or notch in the upper end of thecan-body to receivetlie inturned flange or shoulder at the lower edge ofthe slip-cover iange of the cover after the can has been opened and thus adapt the can to be again closed by a slip-cover, substantially as specified.

Q. A tongueless-tearing-strip hey-opening can, having deep iange-cover and a body fitting and projecting' within the cover-Harige, the deep dange of the cover comprising a lower or soldering Zone, an upper or slip-cover flange Zone, an intermediate or tearing-strip zone, the deep iiange of said cover having parallel scores or weakened lines, and a tongueless tearing-strip provided with a transverse score extending across the saine, and a lzeyinsertion groove at the upper score of the tearing-strip adjacent to said transverse score; adapting the can to be opened by a sharp or chisel pointed key, the upper end of the canbody opposite the key-insertion groove being free to bend or yield inward as the key is inserted through the cover-Harige, and thus enable the liey to be inserted, substantially as speeilied.

3. A tongueless-tearing-strip key-opening can, having a deep iiange-cover and a body litting and projecting within the cover-flange, the deep "tl-ange of the cover comprising a lower or soldering' zone, an upper or slipcover flange zone, an intermediate or tearingstrip zone, the deep flange of said cover having parallel scores or weakened lines, and a tongueless tearingstrip provided with a transverse score extending across the saine, and a hey-insertion groove at the upper score of the tearingstrip adjacent to said transverse score, adapting the can to be opened by a sharp or chisel pointed hey, the upper end of the can-body opposite the key-insertion groove being free to bend or yield inward as the liey is inserted through the cover-flange, and thus enable the key to be inserted, the inward bend or notch at the upper end of the can-body produced` by the insertion of .the

key receiving the inturned flange or shoulder at the lower edge of the slip-cover flange of the cover after the can has been opened and thus adapting it to be again closed by the cover as a sli p-eo ver, substantially as specified.
