FRUIT-JAR.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed December 7, 1906. Serial No 346,816.

1 To all whom it may concern:

Be it known that I, GEORGE F. WELL- HOUSE, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in Fruit-Jars, of which the following is a specification.

, This invention relates to fruit-jars, and the primary object thereof is to so construct the same and the closing device therefor that all air will be effectually driven out of the jar by the seating of the closing device, thereby preventing the spoiling of the contents, due to the presence of air ordinarily retained in jars for reserving fruit, etc. after the closure is mac e.

I accomplish the foregoing by providing a Vent from a point on the inside of the jar be low the top, to a point on the-outside thereof at or near the top, through which the air and surplus contents of the jar are driven out by the forcing inward of the closing medium, and which when completely seated, serves to seal the inner opening of the vent.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts constituting the invention to be hereinafter referred to and illustrated in the accompanying drawings which form a part of this fipeciiication in which is shown the preferre embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings, in which similar reference numerals indicate like parts in the different figures: Figure 1 represents a vertical, central section of the upper portion of a jar filled with liquid, with the closure device in the position which it assumes before being seated; and, Fig. 2 is a view similar to Fig. 1 with the closing medium in position.

In the drawings, the reference numeral 1 indicates the upper portion of a fruit ar, which may be constructed in any form best suited to the uses to which it is to be put; and in order to illustrate this invention, the drawings show a jar provided with a short neck 2 terminating in a beading 3 having on one side an integral pouring lip 1. Extending from a point on the interior of the neck of the jar to a point preferably on the bottom floor of the lip 4 is a vent5 of a suitable diameter to permit the surplus contents of the jar to escape therethrough.

The sealing medium illustrated in this case consists of a cork 6 of such an appropriate diameter as will effectually close the jar, and of such a depth that when completely seated, it ill cover the lower inner end of the Vent 5.

In closing a jar constructed in accordance with this invention, I preferably fill the jar with the liquid which it is to contain, to a height substantially equivalent to that shown in the drawings, and then place the cork 6 in the position indicated in Fig. 1. This cork is then forced downward, which drives out the surplus liquid tlnough the vent 5 until the cork has passed the lower, inner end thereof, which effectually seals the same.

In order to effectually exclude all air from the jar when sealed, experience has shown that it is best to fill the same as shown in Fig. 1, so that when the cork 6 is placed in the position therein indicated, it will rest on and be in contact with the liquid itself, thereby avoiding any air space between the cork and liquid, and as the cork descends, no air is permitted to gather thereunder, and when the cork has reached the position shown in Fig. 2, it has closed the vent and sealed the jar with the absolute exclusion of all air.

This device affords an unusually simple and effective means for preserving various substances in liquidv and insures their preservation therein, due to the absence of air, an effect but indifferently obtained by the ordinary jars now in common use. It will be further noted that it will not be necessary to heat the jar or its contents in order to produce the customary partial vacuum ordinarily sought in jars using other sealing means.

What I claim and desire to secure by Letters Patent, is

The combination in a device of the class described, of a jar having a hollow neck provided at the top thereof with a pouring lip with a depressed cavity therein and further provided with a duct formed in the wall of said neck, extending from a point positioned near the bottom of the neck below which it is ICO desired to keep the fluid in the jar and from In testimony whereof I have hereunto set thence outwardly and upwardly to the botmy hand in presence of two subscribing Wittom of the cavity in said pouring lip, and a nesses.

closure device of an appropriate diameter to GEORGE F. WELLHOUSE. force out any fluid existing above the lower Witnesses: end of said duct and of suflicient length when G. E. HUMPHREY,

seated to seal the same. GLENARA Fox.
