GRAY STAUNTON, OF MUSKEGON, MICHIGAN, ASSIGNOR T0 STAUNTON JAR CORPORA- TION, OF BUFFALO, NEW YORK, A CORPORATION OF NEW YORK.
CLOSURE MEANS FOR HERMETICALLY-SEALEB JARS.
Specification of Letters Patent.
Application led May 3, 1913, Serial No. 765,186. Renewed June 9, 1916. Serial No. 102,800.
To all whom it may concern Be it known that L GRAY STAUN'roN, a citizen of the United States, residing at Muskegon, rin the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Closure Means for Hermetically- Sealed J ars, of which the following is a specification.
My invention relates to improvements in vessels to be hermetically sealed.
One of the objects of my invention is to provide in a vacuum package new and improved means for establishing a hermetically sealed joint between'a containing vessel and closure therefor.
More specifically one of the objects of my invention is to so fashion the opening 'of the package and the coperating parts of the closure thereof that the packing, or sealing ring, will be so distorted by the effect of pressure, due to the vacuum tendency within the package or vessel as to provide a broken joint or tortuous passage, between.
the ring and the vessel parts, for the air that ma pass into the jar as a result of any de ects' thereof, thereby more easily and surely to maintain the desired rarefac- -tion, or attenuation, within the vessel.
Another object of my invention is to so form the sealing surfaces of the vessel, and of the cover with whichthe sealing 4ring cornes in Contact, as to be free from crizzles and checks that are usually produced in the surface of molded glass articles at the time when the parts are molded.
Other and further objects of my invention will become apparent to those skilled in the art from a consideration of the following description when taken in conjunction with the drawing, wherein;
Figure 1 is a vertical central'section of `an all-glass preserving jar or vessel, showing the parts in place, as when sealed. Fig. 2 is a plan view of the jar. Fig. 3 shows the parts in their relative separated position in vertical plane, before being assembled for sealing. `lFig. i is an enlarged, fragmentary'sectional view of a -portion of the jar and cover, showing themeans for breaking the seal.
1n all of the views the same reference characters are employed to indicate similar parts.
lin my co-pendng application, vacuum packages, and means for sealing the same,
serial No. 708,965, eiedauiy 12th, 1912,
I have shown one l,means by which a jarl of the character about to be described may y be sealed, wherein a pump, having a base portion resting upon the upper edge of the jar and overlying the cover, operates as a means for exhausting the air within the jar, while the cover,I underlying'the pump base, operates as a check valve during the sealing process. Of course my presentI invention is not limited to the specific means disclosed in my earlier application for the purpose of sealing the vessel, as any means effective for this purpose may be employed.
In the specific embodiment illustrated same. material. rlhe inner surface of the j ar opening is provided with an angular ledge or shoulder, 7, lthe surface of which is atv substantially forty-five degrees l() to a vertical plane, in which is contained the sealing surface 8. rlhese angularly disposed surfaces comprise the sealing surfaces for the packing ring and in the construction of a machine-molded jar these surfaces are usually free from crizzles, checks or cracks.
The cover or closure 6 is provided with an annular, overhang-ing ange 9, having right angle annular contact surfaces 10 and 11. These surfaces are also free from crizzles, cracks and checks usually found` on salient edges in the manufacture of devices of this character, and for this reason they are well adapted for affording a seat for the packing ring.A The ring 12 is referably made of yielding, compressible material, such as pure rubber, or the like. It is preferably rectangular in cross-section, and is of such diameteras to easily slip over the shoulder 11 of the cover 9, its outer diameter permitting it to pass well within the opening of the largest` diameter 8 in the jar 5.
`When the jar has been exhausted of air Patented Jan. 16, 191'?.
The wedging effect of the yielding ring 12 is a large factor toward securing a perfect and effective joint between the jar and the,
cover, and the portion 14 overlying the 11pper, inner shoulder of the jar, increases the difficulty or impossibility of the air in passing into the .jar by the tortuous path thus established.
The over-hanging ledge 9 of the cover 6 is notched as at 15 for access to the sealing ring. To remove the cover 6 it is only necessaryto admit air into thejar 5, and to accomplish, this a pin 16 may be passed into the notch 15, along vthe verticalwall 17 of the cover and between said vertical wall and the inner surface of the ring 12, permitting the air to pass between the ring and the vertical wall, through apertures effected by the insertion of the pin 16, the wall 17 serves 'as a guide for the point of the pin, and permits 'the pin to be pressed between the said wall and the inner surface of the ring without penetrating the ring.
, A vessel once sealed by the means described will remain sealed until the cover is removed in the manner mentioned, and should only a portion of the contents of the vessel be used the vessel maybe immediately resealed and the remaining contents thus preservedfor further use.
The device disclosed 1s sanitary and very efficient, all parts being made of glass eX- cept the-packing ring, and new packing rings may be used with each successiveuse of the receptacle and closure.
bodiment of my invention for purposes of suicient disclosure it is evident that changes -may be made therein without departure from the spirit of the invention and within the scope `of the appended claims.
- Having thus described my invention, what I claim is: I
1. In a device'of the character described, a vessel having an opening bounded by a `vertically extended surface and an adjoining contact with-the inwardly tapering surface ofthe jar, the narrower portion of the ring' confronting the interior of the jar, the vertical wall of the cover being the other boundary of said ring when sealed.
2. In a device of the character described,
a vessel having an openlng bounded by a vertically extended surfaceand an adjoin? ing' inwardly-inclined, tapering surface; a cover having a overhanging flange and an underlying vertical surface, aording an abutment and a seat for a packing v ring respectively; apacking ring, of rectangular cross section, when not compressed, for insertion on said cover before sealing,g.adapt ed to be compressed to a wedge-shaped cross section by contact with the inwardly tapei`- ing surface of the jar, the narrower portion of the ring confronting the interior of the jar, the vertical wall of the cover being the other boundary of said ring when sealed, and a notch in said ange terminating inwardly in the plane of said yring seat along which to inserta pin to break the seal.
In testimony whereof I hereunto` set my hand in the presence of two witnesses. Whlle I hereln have shown a single em GRAY STAUNTON.
