To all whom it may concern:

Be it known that 1, WILLIAM PRATT, of the 1 and Province of Quebec, Canada, have invented certain new and useful Improvements in Tin Cans or Receptacles; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to cans or receptacles constructed of tin or like material and intended to be sealed after filling, opened, and kept in use for some time, the original cover being retained for further use. Ileretofore the constructions for such purpose have been such as to render it somewhat diflicult to set the cover in place both at the time when the cover is first secured to the body and after it c has been removed, considerable diflicultybeing also experienced in removing the cover after its insertion subsequently to the first opening of the can.

My invention. consists in making the cover with a peripheral rim shaped in part to fit within the body and to rest upon the edge of same, the part fitting inside being soldered to the body and forming a beading of special cross-section in such body just below the portion to which the cover is sgldered, which portion, the same as in other well-known forms, has an extended free overlappingend vhereby upon taking hold of such free end and forcibly pulling upon same the portion of the body above the heading will be detached along the line of the beading from the main section of the body and from the cover-rim to which it was soldered, and the shape of the beading and the rim of the cover make it possible to reuse the cover without any degree of trouble. For full comprehension, however, of the. in vention, reference must be had to the annexed drawings, forming'part of this specification,

parts, andwherein- Figure 1 is a plan view of a blank,'s howing the line of the beading aud'the preferable manner of securing the extended free over lapping end for detaching purposes. Fig. 2 is an enlarged transverse vertical section of such blank. Fig. 3' is a perspective'elevation, partly broken away, of the can as originally closed; Fig. 4, a similarview showing the connecting portion of the body partly detached,

and Fig. 5 a similar view showing the can closed by the original cover after having been opened by removing the connecting-strip.

A is the cover of the can, having .an upwardly-projecting-peripheral rim, presenting a vertical portion uparallel to the sides of the can and a horizontal flange a to rest on the top edge of the body.

B is the body, formed from ablank, such as shown in Fig. 1, having a heading h of the form or cross-section shown in Fig. 2 pressed in it parallel with its top edge and at such a distance below the same as to mark oi the upper portion B of the can (which portion is the connecting-strip) at a depth about corresponding to that of the vertical portion a of the cover-rim. This heading 1) is of an obtuse or wide -V-shaped form or cross-section in the main,but has a more acute depression or extension 1) at its apex, the formation of which extension slightly stretches or abrades the coating or exterior of the metal and allows of the easy and uniform detachment of the connecting-strip B along the line of such apex. It will also be noticed that the wide V-shaped form of the head 1) serves to strenghen the cans both before and after the severance of the connecting-strip.

C is an extension at the end of the connecting-strip B, which when the ends of the body are brought together, overlapped (with the end having such extension outermost) and soldered, remains free to project, so that by drawing upon it in the usual way by the use of the flat slotted key Dlindicated in Figs. 3 and 4) moved. hen this is accomplished, a clean smooth upper edge, slightly flared, is left upon the body of the can, and the cover is equally free from any abrasions or unevenness that such connecting-strip is readily remight interfere with its easy insertion into very easy to remove the cover after it has been inserted subsequently to the turing the cans the cover and body can be more readily fitted together, owing to the peripheral rim of the cover being devoid of plain edges for insertion, as in former constructions.

What I claim is asfollows:

opening of the can. I might also point out that in manufae- IOO 1. A tin can or receptacle the cover of which is formed with a peripheral rim shapedin part to fit within the body and to rest upon the edge of same, and the body having an integral detachable connecting-strip, to which the insertedportion of such cover is soldered, and means for detaching said strip, as set forth. 2. A tin can or receptacle the cover of which is formed with an upwardly-projecting pebody and to rest upon the edge of same, the

body having an integral detachableconnecting-strip, to which theinserted portion of such cover is soldered, and said strip having an extended free end to furnish a holdfast for its removal.

3. .A tin can or receptacle the cover of which is formed with a peripheral rim shaped in part to fit within the body and to rest upon the ripheral rim shaped in part to fit within the purposes set forth.

edge of same, and after being soldered to the body-is removable therefrom and capable of reuse by the removal from cover and body of a detach able conneeting-stripprovided by an outwardly-pressed V-shaped beading or depression in suchbody near its upper edge, adapted to be severed at its apex to allow the removal of said strip and present an outward- 'ly-flaring edge for the easy reinsertion of said cover, as set forth.

4. A tin can or receptacle having upon its perimeter a beading, the cross-section of which is of-an obtuse or wide V-shapediform in the main with anextended acute apex, for the WILLIAM PRATT. Witnesses:
