SEAL FOR VACUUM JARS Original Filed Feb. 9, 1926 INV I TOR 071 Q M M RNEY Patented Feb. 3, 1931 V UNITED STATES GEORGE A. SYKES, OF WEEHAWKEN, NEW JERSEY SEAL FOB VACUUM JARS Continuation of application Serial No. 87,003, filed February 9, 1926. This application filed March 13, 1929. Serial No. 346,743.
' My present invention relates to an improved seal for containers .intended to preserve food stuffs andother perishable substances, and more especially for such as are kept under a vacuum.
This improved seal has been found eifective in maintaining a high degree of vacuum where dry substances are preserved insheet metal containers, and I shall describe the seal as so employed although my claims are not all limited to this embodiment of the invention. a
My improved seal is illustrated in certain preferred forms in the accompanying drawings wherein:
Figure 1 is a View of my seal in vertical section.
Fig. 2 is a similar view of a part of the same on an enlarged scale; and
Figs. 3, 4 and 5 are sectional views of preferred forms of rubber rings to be employed in my seal.
The upper part of a sheet metal container of circular form is shown at. 10. This container has a circular opening centrally located at the top and surrounded by a turned in skirt 11 for aifording. a firm frictional fit with the cover.
All around the top of this skirt there is a shallow concave seat 12 and surrounding this seat is the top of the container 13, so disposed as to afford a blunt circular ridge 14 thatforms the external boundary of the seat.
The cover is preferably outwardly convex in the middle as shown at 15, and is sur,
rounded by a cylindrical edge 16 which is spun over to form an external downwardly extending circular ridge 17 so located and proportioned as to fit down approximately over the ridge 14.
In closing the container the seal is formed by placing, between the outer edge of the cover and the top of the container a band of soft rubber 18, which lies principally over the seat 12 and hugs the cylindrical portion 16 of the cover. The band 18 may also be made of paper, or of various fiber compositions. V
In order to insure the rubber oro ther material being made to fill the space under and behind the ridge 17 as completely as possible, when presure is applied, I prefer to use a band 18 that roughly approximates a circular form in cross section, and three forms are shown in Figs. 3, 4c and 5 which conform to this definition and all three of which aiford at least one external ridge intended to be compressed between the external ridge on the cover and the blunt outer edge of the seat 12.
In Fig. 3 is a roughly diamon d-shaped ring presenting an external angle 19 all around the circle.
In Fig. 4 is shown a form of ring wherein the desired eiiect is produced by a circular cross section having oppositely disposed circular teats 20 within and without.
Inasmuch as the external teat 20 is alone desirable to afiord an extension under the circular ridge 17 on the cover, the form shown in Fig. 5 may be used instead of that shown in Fig. .4.
It will, of course, be understood that after production of a vacuum Within the container and the compression of the cover into place as shown in Figs. 1 and 2, the band or ring will be squeezed out of its original manufactured shape and will more or less entirely fill the space inside the ridge 17, as shown in Fig. 2.
It is to be further understood that my invention is not confined to the use of a particular form of band or ring. In some cases I have found the ordinary flat ring of thin rectangular cross section to be eflective.
This application is a continuation of my application Serial No. 87 ,003, filed February 9, 1926.
What I claim is:
1. A container having an opening surrounded by an inwardly extending skirt, and a top With a shallow concave seat surrounding the opening and bounded on the side away from the opening by a blunt ridge, in combination with a cover having a portion tightly fitting said skirt and having an external down turned ridge adapted to come down substantially directly over said blunt ridge on" the top of the container, and a ring of compressible material compressed against said concave seat under said ridge on the cover, and having a portion extending outwardly under the downturned ridge on the cover.
2. A container having an opening sur- 5 rounded by an inwardly extending skirt, and a top with a shallow concave seat surrounding the opening and bounded on the side awa from the opening by a blunt ridge, in com ination with a cover having a portion m tightly fitting said skirt and having an external downturned ridge adapted to come down substantially directly over said blunt ridge on the top of the container, and a rubber rin compressed against said concave seat um er said ridge on the cover, and having a portion extending outwardly under the downturned ridge on the cover.
3. A seal as in claim 1 wherein the ring has a roughly circular shape in cross section aflording an external ridge when compressed which extends under the downturned ridge in the cover.
4. A seal as in claim 2 wherein therubber ring has a roughly circular shape in cross section affording an external ridge when compressed which extends under the down turned ridge in the cover.
In witness whereof, I have hereunto signed my name.
so GEORGE A. SYKES.
