and useful Improvements'in Hermetic (310-.

, sures for Receptacles, of which the following is a full, clear-,and exact specification,

This invention relates to improvements in Closures forthe hermetic sealing of jars, tumblers, and other rece tacles.

Figures 1 and 2 of t e drawings are en- I larged fragmentary side views in section of this im roved closure as applied to a plainrimmed tumbler arranged to seal against an outer zone of the tumbler-rim, Fig. 1 showing the parts in the position occupied by them during the air expelling or exhausting operation, while Fig. 2 shows the closure in its sealed position. Fig. 3 is a more complete side view, partially 1n section, of a tumbler with the gasket and cap insealed condition. :Figs. 4, 5, and 6 are views corresponding to Figs. 1, 2, and 3 and showing the parts arranged to seal the gasket against an inner. zone of a plain tumbler-rim. Figs. 7 and 8 are fragmentary side views in section of this improved closure as applied to a shouldered jar, the two figures showing the parts in their unsealed and sealed condition, res ectively.

This improved closure finds its c 'ef utility in the form known as a,wedging closure, in which the gasket is com ressed at an angle against a peripheral edge or shoulder of a re' .ceptacle by means of a tapering or flaring cap. The gaskets most commonly used for these wedging closures are of circular or other compact cross-sections These gaskets are sn 7 ported prior to the sealing operatiori just above the shoulder or edge a ainst which they are to be compressed, an it is necessary'to deform agasket of circular crosssection to a considerable extent from its original form in order to carry a sufficient amount of it across the sealing edge or zone of the receptacle upon which it is to be compressed. Inasmuch as the gasket should rest with comparative looseness'upon its seat during the air-exhausting operation,

it follows that the deforming of the gasket to carry it across its sealing-seat must take place during the sealing operation, which usually must be a very Moreover, the sealin inside the hermetical quick operation.- operation takes place y-sealed retort and bewith certainty yond the observation and direct control of form of gasket depend almost wholly upon the form and "uniformity of the sealin -seat and the cap' and upon the manipu ative methods employed in the sealing operation.

The gasket used in this improved formof closure is particularly well adapted for use in the wed ing ty e of closures, since it is comparative y thic at the middle portion, at which the rincipal pressure is applied, and thin towar the edges, where less rubber is required for the sealing o eration. One of these thin edges is utilize to project across the sealing-seat while still in its initial or airerrp'elling condition, thus insuring a safe and certain positioning of the gasket as it is originally placed upon the receptacle by the operator, who is thus enabled to observe that each closure is in proper position for the subsequent sealing'operation. Moreover, this form of gasket by disposing the material in the most advantageous manner e'fi'ects an economly in the use of the rubber of which the gas et is made by reducing the cost of the material required for a 'ven number of askets. The most suitab e material now known for these gaskets is a high grade of rubber, which by reason of its increasing use in the arts is constantly increasing in value. Hence economy in its use is a factor of increasing importance.

The closure-gasket here shown is especially suited for the sealing of tumblers, mugs, or other receptacles having plain rims, which have heretofore been difficult to seal on 210- unfits the receptacle for manysubsequenthousehold uses which might be served by a plain-rimmed receptacle, such as a tumbler or mug.

The present invention is therefore shown herein not only as applied to the sealing of a shouldered jar, but alscasappiied to the sealing'of an ordinary glass tumbler, as a goodexample of areceptacle well adapted to a variety of household uses after its original purpose as a sealed'package has been served.

The form of the gasket 26 used in this improved closure is best shown in Fig. 1. The cross-section is approximately that of a parallelogram having oblique angles, the parallel inner and outer sides 27 and '28 of which are coincident with the inner and outer cylindrical faces of the gasket, respectively. The inclined line of the cross-section is at an acute angle with the line-27 and is coincident with the exterior conical surface oi" the gasket, while the line 29 is inclined at an acute angle with the outer line 28 of the cross-section and iscoincident with the inner conical suri'u'e of the gasket. tion of this gasket is approximately that of a rhomboid or a rhombus the two opposite parallel sides of which are coincident with the cylindrical inner and outer faces oi" the gasket, which is, in cliect, a shortcylindcr having oblique upper and lower edges. These oblique upper and lower edges are herein shown to be parallel with each other. Obviously the an .gle ofobli uity may vary from that herein shown, anr these two edges may also differ from each other as to the angle of obliquity. This asket when of proper size will when placediupon the receiving-seat of a receptacle centralize and position itself in proper rela 'tion to the sealing seat with the thin acutc angled edge 33 projected'rwer and below the sealing-seat, as shown in Fig. 1. The edge 33 projects well below the outer edge of the rim 22 and between that rim and the cap flange, thus bringing the thickest portion of the gasket approximately to the position at which it is to be wedged against the rim of the tumbler by the subsequent scaling operation. The thin edges of the gasket above and below the sealing portion thereof constitute safety margins for the gasket to insure the proper positioning of the thicker central or sealing zone of the gasket, the thinning of these edges cfl'ccting a saving of the material of which the gasket is composed, not only without sacriiicing the cilicicncy ol the gasket, but actually increasing that efliciency. The proportions oi" these gaskets and the angles of the respective edges may be varied to any desired extent to suit different receptacles or caps or to suit diil'erent conditions or servicel The closure-cap employed in corn nection with these gaskets may be of different shapes, suited to the dillerent types of receptacles.on which the closure is to be employed. W'hen employed for making a seal upon the outer edge oi a receptacle, the cap may be of the form shown in Figs. 1, 2, 3, 7, and 8, the flan e of the cap being llared outwardly toward its lower edge. In making the seal against an inner edge of a receptacle the form of cap may he as shown in Figs. 4, 5, and c, in which the sealing portion of the flange ilarcs outwardly at the top. In either case the cap is provided witlta gasket-receiving seat, some portion of which is flared or inclined substantially in accordiance with the More technically, the cross-secoblique-

angled face

29 and 30 of the gasket,

this inclined seat being for the ultimate pur pose of wedging the gasket at anangle against the receptacle-rim. The cap 41 (shown in Figs. 1 and 2) is provided with a flange of a generally flaring form, more specifically having an ogee flare instead of astraight flare. The inclined portion 42 is slightl curved; but it approximately conforms to t 1e oblique face 30 of the gasket when resting loosely in the air-exhausting position shown in Fig. 1. Obviously, however, the inclined portion 42 of the cap 4.1 may be straight instead of being curved, or the,

oblique face

29 or 30, of the gasket may be slightly curved instead of being straight. The lower margin of the cap 41 below the inclined. gasket receiving and seal ing portion 42 is preferably adapted to engage with some portion of the cylindrical face 28 of the gasket, thereby aiding to centralize and retain the gasket in-proper position relative to the cap. l i

The cap 45 (shown in Figs. 4, 5, and 6) is provided with an inclined gasket receiving and sealing portion 46, approximately coincidin with the Obll( us face 29 of the gasket 34. This cap is a so preferably provided with an outer flange 4:7, extendingapproximately to or below the lower edge 35 of the gasket, which projects well below the inner edge of the tumbler-rim when resting in the air-exhausting position shown in Fig. 4. This closure is here represented as being adaptedp to wedge against the inside edge of a tumbler-rim. Therefore the gasket 34 is invert ed from the,position which it occu ies when employed ior outside sealing. hown in some of the other figures.) In Fi s.' Tend 8 this gasket is shown as applied to t e making of an outside seal on a. jar '51, having a shouldered sealing-seat 49, which is preferably rounded or chamfered at the zone which is to receive the effective sealing ressure. The

lower'thin ed e 52 of the as et iS'projects across and be ow the'siiou der 49 when resting in its initial or air-exhaustin position,

.cap 50 and the upper portion" f the jar,

thereby extending the supporting area of the asket and the cap intheir relation to, the ar to aid in positioning them thereon before sealing without having an unnecessary and undesirable bulk or thickness of the gasket at its upper edge, the'thinness of the edge perinitting the cap to tit more closely around the upper portion of the jar. The receptacles employed in makingthese wedging closures are )referably provided with a more or less roundedor chamlcrcd scalin -seat, upon which the wcdging pressure of t e gasket is received.
