CAN.

Application tiled April 16, 1925. Serial No. 23,474.

My invention relates to cans of that type adapted to be openediby removal of an encircling tearing stri and to be temporarily closed, after being rst opened and during the time the contents are being consumed, by replacement of the upper severed part of the can as a reclosure` member.

Cans of this general type have been extensively used in recent years and are highly desirablefor many types of products. The usual construction involves the use of a sep-4 arate interior collar protruding above the tearing strip and providing a friction wall upon which the reclosure may be removably positioned. The cost of this additional member and the operations required for securing itin the can necessarily add considerably to the expense of manufacture. It is, therefore, the principal object of my invention to provide a colla-rless tearing strip can which can be manufactured at materially less cost than the ordinary interior collar can and which `will have most of the advanta of the latter, as well as certain others in c erent in its own construction.

A' highly desirable feature. of theinvention is that it may 'be embodied in the or dinary sanitary, or packers type can by a simple and well-known manufacturing operation and thus may be produced with standard machine This is important, both from the stan point of cost and of the character of the resulting container, whichv may be packed, shipped and handled in the same manner as standard cans of the kind indicated.

Other objects and advantages of the inv vention will be apparent as it is better unf dei-stood .from t e followingA description, which,ltaken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings, v Figurey 1 is an elevational view of a can in which my invention is embodied; and Fig. 2 is a view, partly in elevation and partly in section, of the upper part of said can, showing the tearing strip removed and the severed part of the can positioned as a temporary reclosure.

In said dra illust the best manner in which have thus ar contemplated ap lying the principles of my invention, t e reference character 11 indicates the body of the can, which, as stated `abovemay be of the ordinary sanitary or packers type, the ends 12 and 13 being applied in the usual manner. rl`he edges of the body blank are joined in the usual side seam 14 and an encircling tearing strip 15 is formed in the body by means of parallel score lines 16 and 17, which are cut into the blank before the can body is formed. A tongue 18 is provided at one end of the tear. ing strip and the latter is scored diagonally, as indicated at 19, in what is known as a herringbone score, the purpose of these score lines being to insure against tearing through the strip before it is completely removed.

A bead 21 is formed at a distance beneath `the tearing strip and the can is necked-in above said bead, as shown at 22, the necking* sired from a stock of standard can bodies which may be 4on hand. The body diameter, both at the top and bottom, is the same as that of the ordinary sanitary can of corresponding size and may be packed in similar cases and stacked in the same way. Furthermore, end members of standard size may be used and the body flanges may be of usual form and' are not affected by the necking-in operation, The, upper bend v 23 ofthis necked-im part isbetween the score lines 16 and 17, so that the wall diameter above the tearing strip is greater than the wall dianeter beneath said strip. The severed part of the can may2 therefore, be replaced as a temporary frlction closure, engaging the reduced wall part, there being no necessity for the'separate interior collar above referred to.

It is tho ht that the invention and many of its atten ant advantages will be understood from the foregoing descri tion, and it. will be apparent that variousiclhanges may `be made .inthe form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or sacrificing all of its material advantages, theform hereinbefore described being merelyA a preferred embodiment thereof. I claim:

A reclosure cylindrical tearing strip can having in combination a body the top and bottom of'which are of equal diameter, a top and bottom united with said body, said body being necked in at a, distance below the 5 top so as to be formed with a part of smaller diameter than the upper part of the body and also of smaller diameter than the' lower part of the body, and a tearing stripset oi around said body, the upper line of said 10 tearing strip beingA formed on the upper part of the body which is of larger diameter, and the lower line of said tearing strip being formed on the necked in portion of the body,

whereby, after the tearing strip has been removed, the part of the body above the tearing strip will t outside of and around said necked in portion, and the upper part of the can will be in line with the bottom part of the can.
