Application filed June 554, 1922.

To all whom Z1 may concern.'

Be it known that l, ANTHONY ivi. BERNARD, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful improvements in Ready Openers for Gasket-Sealed Containers; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rlhis invention relates to a sealing device for a container of the open top or jar type and especially to a method and means for opening such a sealed container. lt is a common practice to seal open-ended jars with a cap comprising a flange disposed at the side of the container and spaced therefrom, a compressible gasket being disposed between said fia-nge and the side of the container for sealing the same. Such a flange is commonly employed with a cover known as the double seal cover which also contacts the top edge of the j ar, but the use of such a flange is not limited to such a cover. wWhen it is desired to open the jar it has heretofore been necessary to gouge out a piece of the compressed gasket with some implement in order to get hold thereof. After a hold is secured on the gasket or one of the broken ends thereof the same can be pulled from under the said flange and the cover removed. rlhis gasket removing operation is quite troublesome and difhcult, it usually being necessary to place the jar on one side in order to effectively use an implement thereon.

It is an object of this invention, therefore, to provide a method of sealing and sealing means for a jar by the use of which the gasket can be removed with no trouble and little effort.

It is a further object of the invention to provide such a-means comprising a strip of flexible material which is placed around the gasket, said strip having a free projecting portion which can be pulled to pull the gasket from under the sealing flange.

These and other objects and advantages of the invention will be fully set fort-h in the following description made in connection with the accompanying drawings in which like reference characters refer to the same Serial No. 570,422.

parts'throughout the different views. and in which, l

Fig. l is a view in side elevation of a sealed laf;

Fig. 2 is a view in vertical section thereof taken on the line 2-2 of Fig. l, as indicated bythe arrows; and

Fig, 3 is a partial similar vertical section on an enlarged scale.

Referring to the drawings, an open ended container or jar l is shown having thereon a sealing cover 2. The cover 2 extends across the top edge of the container and contacts therewith to form one seal andis further bent to have a flange 3 depending therefrom and spaced from the exterior of the container. A gasket 4, preferably of continuous annular form is disposed between the flange 3 and the side of the receptacle and compressed by pressing inwardly or crimping in the flange 3. This forms a second seal for the jar. The covers 2 are usually placed in position and pressed or crimped against the gaskets by a machine, although the operation may be performed by hand. In order to provide means for opening the ar a strip of flexible material 5 is used preferably made of thin fabric, which strip is passed around a gasket 4, as shown in Figs. 2 and 3 and has its ends depending at the sides of the receptacle. The strip is placed in position with the gasket and when the flange 3 is pressed against the gasket the strip is pressed against the gasket and, being of thin fabric, does not interfere with the sealing operation, the seal being just as tight as if the strip were not used.

l/Vhen it is desired to remove the cover of the jar, instead of it being' necessary to gouge out a portion of the gasket 4 it is only necessary to hold the j ar and pull upon the ends of the strip 5, a portion of the gasket is thus pulled from beneath the flange 4 and the gasket can be quickly peeled or drawn from under said flange entirely around the j ar. The cover 2 can then be lifted.

From the above description it will be seen that applicant has provided a simple and eflicient method of sealing a jar using means by which the sealed gasket can be very easily removed and the cover then lifted. The strip of material merely hangs at one side of the jar while the same is sealed or while the same is being handled in the trade. lf desired, the ends of the fabric can, of' course be placed under any label which it may be desired to add to the jar during the commercial handling thereof.

lt will, of course, be understood that varin ous changes may be made in the method or in the form, arrangement and material of the apparatus without departing from the vscope of applieants invention, which, gen-y erally stated consists in the matter shown and deseribec and set :forth in the appended claims.

What is claimed is:

l. The method orP sealing an open top container comprising positioningl a cover thereon having a flange spaced from the exterior of said container, placing a gasket between said flange and said Container, placing a strip of thin flexible material trans versely around said gasket so as to depend at the side rolf said container and pressing said flange against said gasket and strip to provide a tight seal.

2. A sealffor an open top container and opener therefor, comprising, a cap having flange spaeedfrom the side of said container, a gasket compressed between said flange and the container and the strip of think flexible material passed around said gasket and having a freely extending portion whereby said strip oan be pulled to extract a portion of lsaid gasket from beneath said flange.

3. The method of sealing a jar consisting in placing a cap thereon, in Contact with an annular gasket and placing a strip of thin flexible material around said gasket, said strip having a freely extending portion which can be pulled upon to remove a portion of said gasket from beneath said cap.

4l. A sealing and opening structure for a jar comprising, a cover, a gasket compressed between the same and the exterior of the jar, and a strip 0I" thin flexible material passing transversely around said gasket and having a freely extending portion at the exterior of the jar.

'5. A sealing structure for an open top Container comprising, a oap inelosing the top of said container and having a fiange projeeting downwardly at the side thereof, a gasket compressed between said flange and the exterior of said Container, andA a strip of flexible material passed transversely around said gasket in a plane extending substantially at right angles to the annular plane of said gasket, said stripbeing compressed with said gasket between said flange and container and adapted to be pulled to draw a portion of said gasket from underneath said flange. v

lntestimony whereof I affix my sifrnature. l
