CURTIS L. LYNCH, OF.CHERRYFIELD, MAINE.

CONTAINER PACK.

Application filed October 22, 1923. Serial No'. 669,945.

To all 'UIZOLHL '52 may concern:

Be it known that I, CURTIS L. LYNCH, a citizen of the United States, residing at Cherryl'ield, county oi ll ashington, ,State of hilainc, have invented certain new and useful Improvements in Contain-er Packs, oi which the following is a specification.

in the n'eservation oi perishable food stuli's by sealing in closed containers, the canning process is greatly simplified and certainty of preservation greatly increased it air is excluded from the pack or it present is exhausted.

While the principles of preservation in vacuum or partial vacuum have been well understood and quite commonly practiced under various methods, the practice has been seriously limited by the expense so that domestic or small packs under vacuum have not been possible.

It is the object of my invention to provide a simple and inexpensive pack and as a basis "for such I contemplate a container or which may be of general standard characteristics, but which will make possible practical exhaustion after filling, wl'iereby it is possible to preserve even. fresh fruits and vegetables'and all without added expense or difiiculty.

Vi hile capable of embodiment in somewhatvaried forms and capable of use in a variety of methods and for almost all of the foods usually canned or preserved, i will without sin .oration set forth only one simple form as a basis oi my disclosure. This illustrative embodiment however will readily suggest to those skilled in the panic incart and to the manuiacturers oi preserving containers the other and more expensive forms which. may prove justified in coin mercial use or more extended domestic use. 'lhroughout specification and drawings like reference characters are employed to designate the parts and in the drawiu Fig. 1 is a central vertical section of a container in accordance with my invention.

liig. 2 is an end view thereof. Fig. 3 is a view showing; the exhausting step.

Fig. l is a view showing the jar sealed, and

Fig. is a view showing a nippled cover.

in providing a container in accordance with my invention a glass yar as 1 may be formed in the cover as at 4- and in both forms the nipple is protected in its recessed position.

in connecting with the exhausting,- pump or system the end of a. tube T can h slipped ov r the nipple l and allowed to grip under the shoulder formed by the cup 6. Upon the removal of the tube T the cup 6 is sealed preferably by wax or other fusiblesealing means.

Care must be taken of course in effecting his sealing without loss of vacuum, especially since in the usual domestic pack the air exhaustion is never very complete, although with the usual simple pump sul'licient exhaustion is had for practical purposes. There is need however to conserve the partial vacuum and in order to insure this where dependence can not be placed on the dexterity of the operator, I provide preferably an initial sealing of the vent 5 by a. soft paraitin filling P. This may be carried up as shown in Fig. 3 to fill the cup 6. Be fore the exhausting tube T slipped on the nipplethis filling P ispunct-ured to vent the contents; When the air is exhaust-ed the tube ll can be pulled oil with a slight lateral wiping movement of the linger which will smear over the puncture in the para'tiin and prevent the inrush of. air.

The cup 6 is preferably permanently sealed by sealing wax which may be applied as a disc or water shoved into the cup and fused in place.

lVhen so sealed the jars will stand any normal amount of handlingand yet may be refilled after the contents are used.

Various modifications in the form of my device may be resorted to without departing from the spirit of my invention it within the limits of the appended claims.

What I therefore claim and desire to secure by Letters Patent is:

1. A preserving container comprising an enclosed vessel having one Wall recessed and vented, and agnipple Within said recess; and below the surface of said Wall, and enclosing said vent and adapted to receive aneX- haust connection. a

2. A preserving container comprising a jar having a recessed bottom, a vent throughsaid bottom, and an exterior nipple enclosingsaid vent and disposed Within, said recess and below the bottom of the jar, and 1 adapted to receive an exhaust connection.

3;:A preserving container having a recessed end With a vent therethrough, and a nipple enclosing said vent and disposed below the plane ofthe container end and 15 adapted to receive an exhaust connection.

In testimony whereof I afiix my signature.

' CURTIS L. LYNCH.
