citizen of the United States, residing atlaccompanyingdrawings.

Columbus', in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Preserving-J ars, of which the following is a specification.

My invention relates to preserving-jars, and has for its object the provision of a device of this character provided Witha cap which will not be liable to become disengaged from the jar during transportation of the device.

' Itis desirable in packing soups, meats, and other articles of food to employ a jar of substantially the form shown in Fig. 2 of the This jar is widest at its mouth and is muchythe shape of an ordinary glass tumbler. When a jar of this general form is used, the contents thereof may be readily removed, there` being, no shoulders or`recesses to retain the contents, as is thefcase when a jar having a reduced neck is used. It has been found, however, that when ordinary jars of this character are packed the fact that the sealing-caps are wider than the Widest portion of the jar brings said caps into contact with each other,

and the edges of the caps engaging with each vother during the movement of the jars inci- `dent to transportation loosens the caps and permits the contents of the jar to ow therefrom. It has been found in some instances that as high as twenty per cent. of the material shipped in a crate or box has been lost from thscause.

It is therefore'an object of the present invention to provid-e an efficient sealing-ca' for a jar of this kind, in combination wit means for preventing the edges of said caps from coming into contact with each other, whereby the foregoing difficulties are obviated.

Further objects and advantages of the invention will be set forth in the detailed description which now follows. In the accompanying drawings, Figure 1 is a side elevation of a sealingfcap, which will be hereinafter described, showing the shape of said cap before it has been crimped upon the jar. Fig. 2 is a vertical section of a jar constructedin accordance with the invention and lhaving the sealing-cap applied thereto, and Fig. 3 is a fra mentary view of aportion of the cap after it as been crimped 'upon the jar.

y lLike numerals designate corresponding parts in all of the figures of the drawings. -Referrimrg; to the drawings, the numeral 5 designates'a jar the sides of which flare outwardly toward the to of the jar. Formed upon the outer face o the upperportion of the j ar are annular rounded ribs 6 and 7, the rib 6 being somewhat smaller in diameter than the rib 7 and being cut away, as at 8, to form a shoulder 9. A cap 10, which flares outwardly at its lower edge 11 before it is placed in position upon the jar, is adapted to -olose the top of saidjar. After the contents of the jar have been placed therein an elastic ring 12 is placed around the cut-away portion 8 of the-rib 6, the lower edge of said ring resting upon the shoulder 9. The cap 10 is then placed upon the jar, after which the air is exhausted from the jar in the usual manner, it being understood that the formation of a vacuum in the jar takes place before the cap is crimped upon said jar. The cap is then crimped, as illustrated in Fig. 3, the inturned portion 13 of the cap resting in the recess 14, formed between the ribs 6 and 7. The extreme ,lower edge of the cap then lies upon the upper portion of the rib 7 and is directed outwardly to permit the vready insertion of a tool thereunder when itis desired to remove the cap.

When a number of jars constructed as illustrated in Fig. 2 are packed side by side, the ribs 7 thereof contact with each other and separate the caps. In some instances these jars are packed in pasteboard cylinders, at which time the rib 7 prevents the lower edges of the caps from coming in contact with the walls of said cylinders, thereby protecting the caps and preventing the accidental displacement thereof.

The seal provided by the present construction is of such nature as to permit the contents of the jar to be boiled after the cap has finally been crimped thereon.l This final boiling sterilizes the contents of the jar and effectually removes any germs which may be containedtherein. This renders it possible to pack goods of the nature setforth without the use of preservatives of any kind. It is a well-known fact that boracic acid and other injurious preservatives are used in packages which are not completely air-tight to prevent the goods from spoiling. i

From the foregoing description it will be seen that simple and efficient means are pro- IOO IOS

vention; but while. the elernents set forth are well adapted to serve the purposes for which they are intended it is to e understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

1. A jar having outwardly-Haring walls and a pairotl annular ribs extending around the jar at the top thereof, and a cap which closes the jar and has a depending flange engaging the under side of the upper of the ribs, the lower of said ribs being'of greater diameter than the upper rib whereby when a plurality of said jars are placed side by side, said lower ribs prevent the caps from contacting with each other.

2'. A jar having outwardly-flaring walls and a 'pair of annular ribs extending around the jar at the top thereof, and a cap which closes the jar and has a depending flange engaging the under side of the upper of the ribs, the lower of said ribs being of greater diameter than 'the upper rib whereby when aplurality of said jars are placed side by side, said lower ribs prevent the caps from contactingr with each other, and an elastic ring located in the recess formed about the upper edge of the Jar.
