JAR AND cLosURE THEREFOR Filed June 3, 1930 lnvenlor A llorney Patented June 7, 1932 UNITED STATES PATENT OFFICE JAB AND OLOSUBE THEBEFOB Application med I une 3,

This invention relates to structural improvements and refinements embodied both in the construction of a fruit jar and an especially designed closing cover therefor.

The invention has more particular reference to the style of jar which includes a reduced neck and a cover which lits thereon and which is retained in place through the medium of a hardened fparaiine seal.

The novel structural eatures defining the distinguishable contributions to this art will become more readily apparent from the following description and drawing. In the drawing: u

Figure 1 is a fragmentary view primarily in section showing the improved neck construction and the seal retained telescopically fitting cover.

Figure 2 is a top plan view of the jar neck construction with the cover removed to expose the structural details.

In'Figure 1, the body of the jar is designated by the reference character 3 and this is of suitable proportions and material. The reduced neck is re resented at 4 and this joins to the body t rough the medium of a curvate web 5 which forms a connecting shoulder. It will be noticed that the neck 4 is slightly tapered, that is, thickened toward the free upper edge portion thereof.

Adjacent the shoulder there is an outstanding circular ledge 6 and just inward of this is an annular channel 7 which may be designated as the primary sealing channel. There is also a similar channel formed in the upper edge of the neck and this may be distinguished as the secondary channel. This secondary channel includes inner and outer stepped walls 8 and 9 respectively. The in- Q0 ner wall is higher'than the outer wall to cause sealing wax to overiow the outer wall and to run down the outer surface of the neck. ,y It will be noticed that in forming this sec- *3 ondary channel, the glass or other material from which the ar is made is so shaped as at 10 to form a sort of convenient pouring spout for aiding in emptying the contents from the jar by tilting. The intermediate portion of the upstand- 1930. Serial No. 459,055.

ing neck 4 is provided with a circumferential groove which serves to accommodate the packing ring 11. This is of a conventional rubber gasket construction.

The cover is generally re resented by the l5 numeral 12 and is prefera ly composed of glass. The marginal rim portion 13 has its lower edge fashioned to fit firmly down into the primary channel 7 In addition it has an outstanding flange 14 which cooperates with 00 the ring-like ledge. The inner walls of the rim 13 is formed with a groove of semicircular configuration to accommodate the projecting half of the packing ring 11.

The disc-like portion 15 of the cover has 55 a concentrically arranged annular depression 16 formed therein to receive the projecting up er edge of the wall 8. In addition this part o the cover carries a depending annulus 17 which fits down in the chaimel walls 8 70 and 9. These two channels might well be de-V fined as circular keyways and the portions o f the cover itting'therein may well be designed as keys fitting telescopically thereinto.

The gist of the jar construction is in the 'provision of the reduced neck which merges into the body portion through the medium of a web defining a shoulder, said shoulderrhavingthe primary channel or keyway therein and also having the outstanding annular ledge associated therewith.

In addition, the neck is characterized by the provision of the semi-circular circumferentially arranged groove for accommodating one-half portion of the gasket ring. Then there is a thickened tapered design of this neck with the terminal decidedly increased in thickness which serves to permit the formaP tion of the secondary channel and which denes the inner and outer walls 8 and 9.

The companionate features of the cover 12 comprising the iiange 14 and the annular depending key 17 render it distinctively novel. It is understood that in use the inner and outer main and auxiliary channels are filled with paraiin. Then the cover is shoved down over the neck. When the paraiin hardens a permanent closure is provided.

It is a feature of this closure that the rubber gasket is held and engaged in place. It also avoids any necessity of abnormal clampinv upon the jar and closure.. A

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawing. Therefore, a more lengthy description is regarded as unnecessary.

Minor chan es in sha e, size, and rearrangement of etails coming within the field of invention claimed may be resorted to in actual practice if desired..

I claim:

1. As a new product of manufacture, a jar comprising a body open at its top and having a reduced portion defining a neck, the juncture between the neck and body defining a shoulder and having a primary annular channel formed therein and an outwardly projecting annular ledge therewith, the terminal upper edge of said neck being thickened and formed with a secondary channel and a cover fitting over the neck and having a depending rib on the underface of its top portlon, fitting in the -secondary channel with its lower edge fitting in the primary channel, and said cover having an outwardly extending flange adjacent its lower edge for engaging the annular ledge and sealing material in both channels, between the flange and the ledge and between the cover` and the neck.

2. As a new product of manufacture, a jar comprising a body open at its top and having a. reduced portion defining a neck, the juncture between the neck and body defining a shoulder and having a primary annular channel formed therein and an outwardly projecting annular ledge therewith, the terminal upper edge of said neck being thickened and formed with a secondary channeL' said secondary channel having its inner wall of a height greater than the outer wall to facilitate pouring of the contents from' the jar and to promote overowing of sealing fininga shoulder and having a primary annular channel formed therein and an outwardly projecting annular led therewith, the terminal upper edge of sai neck being thickened and formed with a secondary channel, said secondary channel having its inner wall of a height greater than the outer wall to facilitate pouring of the contents from the jar and to promote overflowing of sealin material over the top of the short wall, an a cover fitting over the neck and having a depending annular rib on the under face of its top part fittin in the second channel, and the lower edge o the cover fitting in the rimary lchannel and an outwardly exten ing flange adjacent the lower edge of the cover engaging the ledge, the under face of the top part of the cover having an annular groove therein for receiving the edge of the high wall of the secondary channel, said neck having an annular groove in its exterior face intermediate the ends thereof and the depending part of the cover having an annular groove in its interior face which aligns with the last-mentioned groove when the cover is'in position, and a packing member located in the annular space formed by said two grooves said sealing material located in both channels, between the flange and the ledge and between the cover and the neck.

In testimony whereof I aiix my signature.
