The invention relates to new and useful improvements in metal containers, and more particularly to a metal container of the r1p strip type provided with an inserted collar with which a cover makes slip engagement for re-closing. y i r i object of the invention is to provide a collar fora container of the above type made from a strip of metal having the ends thereof locked together byfthe' inter-engaging and folding of metal parts disposed relative to each other, so'that the outer face of the collar is of uniform diameter and makes intimate contact with'the inner face of the body wall of the container throughout the entire cir cumference of the collar.

.In the drawing i Figurel is a sectional view'through a container with the improved collar inserted therein; L

"Fig.2 is a sectional view on the line 22 of Fig. 1,'and-' f .Fig. 31is a view showing the ends of the collar detached andwith the holding lugs positioned at right angles to the face of the collar, 'andalso showing the depressions in the inner lap which are formed when the lugsfare turned down and pressure'applied thereto. g

The invention is directed to a metal container which includes a body portion having the ends oined thereto preferably by double seaming. The body wall adjacent one of the double seams is provided with score lines setting off a rip strip to which a key may be of the strip overlap each other. The inner lapping end is provided with an elongated open ng extending lengthwise of the strip; The other'end of the strip is provided with lugs which are cut from the strip and-bent so as to extend at right angles thereto. These lugs are so positioned that they pass through said elongated opening, afterwhich the lugs are folded down against the inner face of the strip. After the lugshave been folded down, pressure is applied and this will cause the lugs to form depressions in the inner lapped section, forcing the depressions into the openings in the outer lapped section formed by striking up the lugs. The end of the inner lapping portion is offset from the body of the strip so that the'outer face of the strip is of uniform diameterfthroughout, and

willmake intimate frictional contact with the inner face of the wall of the container body. I

Referring more in detail to the drawing, themetal' container as shown includes a'body portion 1 which isprefera'bly cylindrical in shape. Only one of theends is shown. This end is indicated at 2 and it is secured to the body portion 1 by a double seam 3. The wall of thecontainer body is provided with a score line 4 and also a score line 5. These score lines 4.- and5 setoff a ripping strip 6to which a key may be applied for tearing away the ripping strip and thus releasing the end or cover 2 from the container body. Inserted within the container prior to the applying of the end thereto, is a'collar 7 The collar together. The end f the collar is the outer lapping portion. This end is provided with lugs 9 and 10 which are struck up from the metal in th'e'collar, and are initially formed so collar.

7 has the ends thereof lapped and secured f 11 is formed, and by the striking up of the lug 10,'an opening 12 is formed. a

The end 13 of the collar band is the inner lapping end. This end 13either prior to the r oiningv of the ends, or during the joining of 1 a construction so that when the two ends are joined, the outer face of the collar adjacent the line 14 on one end of the collar, will be flush with the outer face of the other end of the collar. This produces a collar, which as clearly shown in Fig, 2, is of uniform diameter throughout, and therefore, the outer face of the collar will make intimate contact with the bodywa'll 1 of the container, as shown in this figure. The end 13 of the collar is provided with an opening 16 therethrough adapted to receive the lugs 9 and 10. After the lugs have been inserted in this opening, theyare folded down on to the inner face of the endsection118, andpressure applied. The pressure will cause the metal at the ends of the opening 16 to be depressed or forced into the openings; 11 and 12 as indicated at 15,15. This not only aids in the: locking of the two ends together, but it also produces a CI1Si3I'1lC1 contents of the container.

tion wherein the lugs are substantially flush with the inner face of the lapping section 13. The upper edge of the section 13 is inclined asindicated at 17 so" as to avoid any sharp inner corner at the upper edge portion of the collar,-

From the above it will be apparent. that I hav'eprovided a collar .for insertion in-a container body which is formed from a strip of metal having the ends thereof firmly locked together by an interlocking and folding of the metal parts ofthe collar. These parts are so disposed that the outer face of the collar is substantially of uniform diameter throughout so that when it is placed within the container body, it will make intimate contact with the inner wall of the container body substantially throughout the entire circumference of the collar. After the container is opened, the material in the container is passed through thecollar in the dispersing of the If the content is of a liquid type, then it is quite essential that the collar shall make a liquid-tight joint or connection with the body wall throughoutthe entire circumference of the collar. Otherwise, the liquid will pass under the collar and will run down the outer wall of the container instead of through the collar and discharge from the outer lip edge of the collar. No matter whether the liquid content is poured from the container over the connection betweenthe ends ofthe collar or at any other place, there is no chance for escape of the liquid beneath the collar, for the reason that the collar, when the ends are joined, as'described above, makes an intimate liquid-tight contact with the container wall throughout the entire region where the ends are joined.

fore, the collar may be made so that it will have a tight frictional grip with the body wall when inserted therein, andcan, at the same time, be rounded into form and forced into thistight gripping contact with the wall of the container.

The score lines 4 and 5 are so disposed in I the present embodiment of the invention, that when the rip strip is removed,th'ere will beat portion 18 of the body wall left-attached to V the end 2 which projects downwardly so as to make an outside slip engagement with the collar 7 for re-closure purposes. While I have shown the collar as used in connection with a container having an outside slip portion formed from the bodywall, it will bev understood that this depending portion remaining attached to'the end. and forming therewith a cover, may be otherwise formed. Likewise, the collar instead of being substantially of uniform diameter throughout and without any, rolled edge, may be otherwise shaped. The essential features of the invention reside in the joining of the ends of the collar so that the outer surface of the collar is of substantially uniform diameter through as to overlie the rip strip, one end of said.

collar having an offset portion overlying the other end of the collar, one end of said collar having an opening: therethrough and the other end of said collar having a lug struck up from the metal'forming an opening adjacent the lug, said lug extending through the opening in the other end of the collar and folded down against the face of the end of the collar and depressing a portion of said end into the opening formed by striking up the lug.
