FRUIT-JAR-SEALING-R ING 0?ENER.

Application file-d August '7, 1922. Serial No. 580,223.

T 0 all whom it may concern v Be it known that wel /ennui. M. SAUN- nnns and LLOYD V. ROY, citizens of the United States, residing at Reading, in the 5 county ot Middlesex and State of Massachusetts, and Beverly in the county of Essex and State of Massachusetts, respectively have invented certain new and useful improvements in Fruit Jar Sealing Ring Openers, of which the following is a specification. i

This invention has reference to fruit jar sealing ring openers and its object is to provide means, whereby the fruit jar seal may be broken when it is desired to gain access to the contents of the jar. a 'Q 1 Ordinarily, fruit jars are providedjwith sealing rings of rubber or like material and often times considerable ditliculty is bad in breaking the seal with the result that sometimes an implement is employed which is liable to break or injure'the jar'in some way in the eilort to remove the top of the jar. Even with the use of a tool provided for the purpose, difficulty is often encountered in loosening the top becauseof the vacuum conditions present. f

" In accordance with the invention, the fruit jar ring instead'of being a simple flat I so ring of rubber, is a composition ring having.

the usual flat rubber ring elements, and in addition thereto another element of similar character and possessing considerable strength whereby the sealing ring may be ruptured so as to admit air to the interior of the jar and thus break the vacuum, after which the to of the jar may be easily Teinoved,'.usuall y by unscrewing, conditions no longer being present. so A sealing ring constructed in acc'ordan e with the invention, includes the usual: rubber ring with an interior member of rubberized fabric which may serve as a tearing member and is removable from beneath the jar cap to the exterior thereof whereby the fabric may be grasped by the fingers of the human hand and withdrawn in a manner to se 'iarate the rubber ring and admit air to the interior of the jar, thusbrealring the vacuum.

It is essential that the rubberized cloth or othertearing element run through the ring and it may extend part of the way around the inside of the, ring. It is not necessary that the rubberized element be sunk flush with the inside circumference although this the vacuum latter arrangement will make a heater finish than otherwise.

cations mark no material departure from the salient features of the invention as expressed in theappended claim.

In the drawings Figure 1 is a perspective view of the upper end of a fruit jar with the sealing ring partially pulled out.

, Fig. 2 is a plan view of the complete sealing ring ready for use.

Fig. 3 is a diametric section thereof; Referring to the drawings, there isshown a fruit jar 1 provided with a top or cover 2 shown as of the screw type, but it is to be understood that any type of jar cover ma be used.

mployed in conjunction with the cap is a sealing ring 3. p

Such sealing ring 3 may be in the mainof the customary llat rubber type to serve as a gasket lodged between the cover meniber'or cap 2 and the top ledge d otthe jar whereby such ring when lodged between the cap and the ledge of the jar constitutes a vacuum proof seal in accordance with. the usual practice in rendering jars vacuum proof. 3

in conjunction with the rubber jar ring is a piece of rubberized fabric built into the rubber ring in such a manner that one end lid till

protrudes from the exterior or outer periphcry of the rubber ring 3 and the tearing strip 5 may be vulcaniz d together with the rubber ring so that lea age under normal conditions cannot take place, the elastic nathe tab is grasped between the thumb and fingers and pulled in a direction tangentiall away from the jar thus resulting in tearlng that part of the rubber ring from which the rubberized fabric protrudes, this tearing action continuing until air is ad mitted to the jar thereby breaking the vacuum so that the cover of the jar may be easily lifted ofi or unscrewed as the case ills of course meansthat the sealing ring is destroyed for any further use, but this is the case so ,far as the life of any sealing ring such as is used on fruit jars is concerned.

Theadvantages of the numerous. There is no danger of the jar employed to open the jar.

invention are or cover being damaged in opening, as so often occurs when an ordinary ring is pierced with a knife, an ice-pick or similar implement, often causing the container to leak when the attempt is .made to use. it again. The jar is quickly and easily opened by a single pull, there beingno hunting for something to open the jar with or for somebody with strong hands. Also there is no danger due to slipping of the implement The composite ring is of very cheap construe ion and plac tically as cheap as the ordin ry variety of 1 sealing. rings and the improved ring is positive 1n operation and in air sealing quality. What is claimed is A fruit jar sealing device comprising a flat sealing ring of compressible material with an inextensible tearing strip vulcanized to the sealing ring along its inner edge and traversing the ring to its outer edge,

and beyondthe latter formed into a finger hold.

In testimonywhereof, We aflix our signatures hereto.
