JAR-CLOSURE.

Specification of Letters Patent. Patented July 11, 1911.

Application filed November 22, 1910'.- Serial No. 593,595.

To all whom 'it may Be it known that I, HERMANN OP DE Hm,

.a citizen of Germany, residing at Wehr,

' Grand Duchy of Baden, Germany, have invented a new and ,useful Jar- Closure,- of which thefollowing is'a specification.

This invention relates to a jar closure of novel construction, and more particularly to novel means for eflectin-g a tight and uni form packing between the jar and its cover.

In the accompanying drawing: Figure 1 is anelevation partly "section of 'a jar provided with my improved closure; Fig. 2 a'bottom view partly in section of the lid and-gasket; Fig. 2? a section through the joint before being'finally closed; Fig. 2 asimilar section through the finally closed joint; Fig. 2-a detail of a modification of 1 Fig. 6 a bottom -view the lid and gasket; Fig. 2 a detail of another modification thereof; Fig. 3 an ele-- vation partly in section of a jar showing a further modification of the lid and gasket; Fig. 4 a bottom viewof the lid. and gasket of Fig. 3; Fig. 5 an elevation partly in section of a-jar showing a further modification; artly in section of the lid and gasket of Fig. 5; Fig. 7 a verticalvsection 'of a further modification of the closure; Fig. 8 a bottom view partly in section of the lid and gasket of Fig. 7; F i 9.

an elevation partly in section of a furt er modification of .the closure; Fig. 10 a bottom view. partly in section of the lid and d is placed between 'jar rimand. lid the width,

gasket .of Fig. 9, and Fig. 11 an elevation partly in section of .a further modification of the closure.

The body a of a suitably shaped jar or vesselis provided with a symmetrically tapering upper edge or rim formed by an inneran'd an outer bevel, s'uch inner and outer. bevels extending respectively to the innerand outer sidesof the vessel. The lid is provided with-a groove 6 adapted to re- I ceive'. said edge and =made of flaring or inverted V-shape in cross section. At' its top or apezrgroove 6 opens into 'a contracted channel or recess c, .-the sides of which are substantially parallel. Channel 0 is symmetf' rical in cross section andis'centered verti cally above'the taper-in edge of. vessel a, When the lid is closed. flat flexible gasket of said gasket .exceeding that of the mouth of groove '6: lThus-when pressure is applied," the gasket be so bent as to lie snugly having s an annular groove i, that receives the outer rim-of gasket d. In'this modlficatmn' the ation the central zone of the gasket will be accommodated within recess 0, so that an undue compression of" the gasket is. here prevented, and the gasket will thus be uniformly compressed .throughout its width.

vertical pressure, and is subjected to a sliding or distending pressure only, so that a uniform adjustment of its particles is ef fected. This even distribution is assisted by a small groove e of the lid arranged concentric. to groove 6. Furthermore as the gasket becomes tightly stretched over the upper edge of the jar, a tight packing is also obtained along its central zone, immediately, below recess 0. It should further be noted,

that if owing to inaccuracies, either the inneror the outer bevel of the jar should not become tightly packed, this will be compensated for, by an increased efficiency of the packing at the other bevel. So also the packing will a-ccommo ateitself to inaccuracies ofthe joint, so that the latter need not be ground true, and a corresponding economy is effected. In order to pre-' vent gasket d from becoming unseated when the jar is opened or closed, it is provided with a] suitable number of inwardly extendin flaps or ears f. From the lid there depen s an inner rim g and above such mm are formed laterally extending recesses 72. adapted for the reception of the ears, so that the In Fig. 2 the recessed. rim 9 is replaced by a number of recessed bosses g dependlng between the flaring top of the jar'and the flaring-sides of groove 6. During this oper-y gasket is held in position without ten,- sion.

Inother words, the'gasket is relieved from from the "lid and adapted to receivev ears f, 1

while in-Fig. 2 the ears are received within apertured keepers g of the lid.

In Figs. 3 and 4 the lid is provided above rim g-with a continuous annular groove 2',

adapted for the reception of the inner rim of gaskets d, while outwardly extending flaps f v constitute jfinger. pieces.

In Figs. 5 and 6 the lid is provided with an outer rim 7 and 8 outer g besides In Fig parts '70, fmay be omitted if desired.

its la-for lugs 15, is provided .with

' In.;F 1gs. 9 and 10 tongue ff and slits k are 9' having slits k for securing the lugs f of gasket d.

retained, while additional projections f of the gasket are received within additional recesses m of flange g.

In Fig. 11 the slits is that receive tongues f, are partly open as at n for facilitating the introduction of the tongues into the slits.

I claim:

In a jar closure a vessel having a symmetrically tapering rim the inner and outer bevels of WhlCl'l extend respectively to the corresponding sides of the-vessel, combined with a cover having a symmetrically tapering groove the walls of which are arranged parallel to the corresponding rim-bevels and having also a channel opening into the apex of said groove, and with a flat gasket removably secured to the lower side of the cover and extending across the groove, said gasket being adapted to be bent over the tapering rim and to be uniformly forced against the groove-walls, whereby the surplusof material congregated at the crest of the gasket is free to enter the channel so as to effect a maximum and uniform compression of the gasket along both rim-bevels.
