Application filed November 15, 1924. Serial N04 75(l,054.
My invention relates to improvements in means for sealing the ends of containers, particularly of the class commonly called tincans, whereby the contents will be securely retained in an air-tight manner and access may be had to the contents by breaking a frangible sealing means.
In carrying out my invention I provide a container, preferably in circular form and'of relatively thin sheet metal, and within one of its open ends I insert a sealing member, such as a disk having a flan e extending toward the adjacent edge 0 the container body, such edge having preferably been indented slightly inwardly, and I then curl such edge of the body inwardly against the flange of the sealing member to force such flange tightly against the can body to provide a substantially air-tight or hermetic seal between such body and flange, whereby the flanged sealing member provides a tight closure for the corresponding end of the canbody. Theopposite end of the body having been left open, permits the contents of the body to be filled through such end and after charging the body a bottom or closure is applied to the body, as by double-seaming the same thereon or in any other suitable way to secure said parts together.
' or more pieces, in the usual way. In con- My invention comprises novel details of improvement that will be more fully hereinafter set forth and then pointed. out in the claims.
Reference is to be had to the accompanying drawings forming a part hereof, wherein Fig. 1 is a sectional detail of a portion of a container body illustrating steps in the construction of my improvement;
Fig. 2 is a similar view illustrating a further step;
Fig. 3 is a sectional view illustrating another step in producing a. container body, provided with my improvement;
Fig. 4 is a partly sectional plan view of part of Fig. 3, the cover being omitted; and Fig. 5 is a perspective view of the breakable sealing means.
Similar numerals of reference indicate corresponding parts in the several views.
The container or can body is illustrated at 1 and may be of any suitable construction, such as an ordinary so-called tin can having a longitudinal seam or a drawn shell, of one structing .my improvement both ends of -*-against the flange 3 thus locking such in contact with its inner wall adjacent to the open end thereof with the outer edge of the flange ad acent to the inner portion of the ducked edge of the container, substan- After the sealing member or disk 3 has been lnserted in the canbody the indented edge portion 2 thereof beyond the sealing memher is curled or rolled inwardly, so that the 1nner edge of the ortion 2 will be turned outwardly and \wil engage the flange 3 of the sealing member or disk and force the same tlghtly against the adjacent inner surface of the container body, as indicated in Fig.3. A convenient means for curling the portlon 2 of the container body against the flange 3 of the sealin disk is to first, in a sulta'b-le machine, partdy curl the portion 2 1nto place without forclng it tightly against the flange 3, as indicated in Fig. 2, and then the container body is passed to a second station in the machine where a second set of curhng rolls engages the edge portion 2 that has. been partly curled and forces it tightly an e tightly between the inner edge or the body I portion 2 and the adjacent surface of the and the container body. The contents of the container body may be charged into the same through the open end thereof opposite the seal 3, and thereafter a suitable bottom or head 4 may be attachedv to such charging end of the body" in any suitable or well known manner, as by double-seaming the flange 4 of said bottom to a flange 5 at the charging end of the body, in a well known l fhen it is desired to extract the contents of the container it is merely necessary .to-
break or cut out the sealing member 3, which tiall-yas indicated in dotted lines in Fig. 1. V
' with a tight fit on the body. The cover may be readily removed by rotating it reversely. An indenture or depression 9 in the cover, adap'tedto fit against the inner surface of the edge portion 2 of the container body,
provides a tight fit to exclude air when the issued Januar I stood that a s ip cover or any other desired which the head or bottom 4 has been seal 3 has been broken or removed. The construction of the cover with the threads and indenture shown in the drawings is similar to the container disclosed in Letters Patent of Charles Gueritey, No. 1,443,682,
30, 1923. It will be underform of detachable cover for thecan body may be provided. f
While it will be understood that after the open end portion of the body has been ducked inwardly and the sealingmeans inserted the top portion of the ducked edge of the body is inverted and squeezed" against the flange 3* of the sealing member, and I have described several steps to'accomplish the purpose specified, my invention is not limited to such steps since the curling in of the ducked edge of the body against the flange 3 may be accomplished in any other desired way.
My invention is not limited to applying the seal. to a body having both ends open, since the seal may beapplied to a body to reviously attached, so that after the contgnts have been charged into the body the sealing member 3 may be applied in manner before set forth, the last named body" including one having the bottom attached by seaming, sol- .said body, the container having a portion adjacent. to its open end curled inwardly and projecting outwardly against the flange, the flange being substantially uncurled, the container portion having its free edge pressing the flange against said wall of the body. "2'. A container comprising a body having an inner sealing member adjacent to one end, the sealing member having a flange extending along the inner wall of Said body, the container having aportion adjacent to .its open end curled inwardly and projecting outwardly against the flange, pressmg the latter against said wall of'the body, the sealing member being'of paper and the inner edge of the curled portion of the body pressing the flangeof the sealing member against the container body.
3. The method of constructing a container having an inner paper sealing member consisting in inserting a sealing member having a flange within the body and indenting an edge portion of the body beyond the sealing member, and curling the indented portion of the body inwardly and turning its edge outwardly against said flange and pressing the latter tightly against the container body.
4. The method oi' constructing a container having an inner paper sealing member consisting in indenting an edge portion of the body adjacent to an open end thereof, inserting a paper sealing member having a flange within the body, and curling the in dented portion of the body inwardly and turning its edge outwardly against said flange and pressing the latter tightly against the container body.
