Description

J. E. BARRANGER.
JAR CLOSURE.
APPLIGATION FILED APR.1,1909.
Patented July 13, 1909.
UNITED sTATEs PATENT oEEIoEy V` `JOSEPH E. BARRANGER, or 'rHILAnELrHm PENNSYLVANIA.
JAR-CLOSUBE.
To all whom it may concern:
Bc it known that I, JOSEPH E. BARRANGER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain .mprovements in Jar-Closures, of which the following is a specification.
My invention relates to that particular class of closures for bottles, jars, tumblers or like receptacles, (hereinafter, for convenience, termed a jar) which are known as vacuum closures and in which the cap or cover is held in place upon the jar by the pressure of air thereupon, a vacuum or partial vacuum having been established in the jar.
The object of my invention is' to so construct a closure of this class that when the cap or cover is subjected to the pressure of the air and is forced downwardly thereby it will exert a properly applied compressing force upon the sealing gasket used in connection therewith and will have no tendency to distort said gasket or displace itfrom its seat below the mouth of the jar, another object of the invention being to so shape the sealing gasket that it can be cut from a tube of proper diameter without waste.
In the accompanying drawing-Figure 1 is a vertical sectional view,on an enlarged scale, of the upper portion of a jar constructed and provided with a sealing gasket and cover in accordance with my invention; Fig. 2 is a similar view, illustrating the relation of the parts to one another after the vacuum has been established, the cover subjected to the air pressure and the sealing of the jar effected, and Fig. 3 is a view similar to Fig. 2, but illustrating a modified construction of the seat formed upon the jar for thereception of the sealing gasket.
ln the drawing, 1 represents part of the body of the jar which has,` on the outside of the same immediately below the mouth, a vertical wall 2 terminating at its basein a horizontal shoulder 3, a rib 4 referably rounded on its outer face, being coated at the angle which would otherwise be formed between the vertical wall 2 and horizontal shoulder 3. j
in connection with the jar thus constructed I employ a sealing gasket 5 of wedgeshaped cross section, said gasket having a vertical face for contact with the wall 2 of the jar anda horizontal face for resting upon the f horizontal shoulder 3, and having inner and outer beveled faces, the inner beveled face,
Specicationof Letters Patent. Application filed April 1, 1909. Serial No. 487,283.`
Patented .my is, 1909.
when the gasket is first applied to the jar, bearing lightly upon the rib 4 at the junction of the vertical wall 2 and horizontal seat 3, as shown in Fig. l.
p The cap 6 has a depending flange with reversely curved portion 7, and when said cap is first applied to the ar this depending flange rests upon the outer face of the sealing gasket 5 but permits ready escape of the air from the interior of the jar when the vacuum is established in the chamber containing said jar.
When downward pressure is applied to the cap the shoulder 3 prevents downward movement of the gasket, and the vertical wall 2 of the jar prevents inward movement of the same, conse nent-ly compression is exerted upon the gas et 5 substantially in the direction of the arrows .r in ifi. 1, so as to force the inner face of the gaszliet over the projecting rib 4, press ilsinner and bot-tom faces lirmly a ainst the vertical wall and horizontal shou der of the jar and drive the surplus material upwardly between said vertical wall of the jar and depending portion of the ca and downwardly on the outside of the horizontal shoulder 3 of the jar, the diameter of the lower portion of the cap being so much in excess of the diameter of the shoulder as to permit this action. l
Below the shoulder 3 the jar has a proj ecting rib 9, which projects slightly beyond the depending iiange of the cap and revents loosening of said cap by protecting t ie lower edge of the liange from upward pressure.
In some cases l may substitute a beveled face 4 for the rib 4 at the junction of the vertical wall and horizontal shoulder of the jar, but the rib is preferred, owing to the positive indentation of the inner face of the sealing gasket caused thereby, and the more secure joint caused by reason of such indentation. j
The wedge-shaped gaskets 5 can be readily cut from a tube without waste, by forming reversely inclined diagonal cuts in said tube.
I claim :u
1. 'Thezeombination of a jar having a vertical face, `a horizontal shoulder and a seat at the junction of the two with a wedgeshaped packing gasket presenting faces for contact with the vertical wall, luirizontal shoulder and intervening seat, and a cap having a portion for pressing upon the beveled outer face of the gasket. h
2. The combination of ajar having a vertidal Wall, a horizontal shoulder end a ribbed I In testinfiony whereof, I have signed my seat at the jlnnetion ofthe two, wlth a wedgename ,to this specification, in the presence of shaped ses ing gasket having faces bearing two subscribin(r Witnesses.
