CLOSURE.

Application fled hi a-1924. serm'mi. 723.930.

The present invention provides improved covering; means for closing.. receptacles,

jars,-fo1 ,example,such that. they ma be closed'quickly and easily, while desired tight- 6 guess of closure may be effected even though the covering means be-hurriedly or carelessly applied. 1

y he nature of the invention will be readily understood by reference to one practical eml -bodiment of the invention, which is shown,

for illustration, in the accompanying drawin s in which:

ig. 1 is a sectional elevation of the open end of a jar and its closure, the latter being shown in the position occupied when fully seated over the mouth of the jar;

Fig. 9;, a view similar to Fig. 1, shows the closure applied to a jar, but only partially seated over the mouth thereof;

Fi 3 is another sectional elevation, showing t e closure applied to the jar in a tilted position, and only partially seated, to illustrate the efl'ect of careless application of the closure.

Jar covers and the like heretofore have been open to certain objections, that apply with particular force to counter displayand dispensing jars or other receptacles, which.-

are intended to be kept tightly-closed, but

so which sales people are required to open and close frequently in making retail sales. With reference to these objections, it' may he said. that covers which have been capable ofmak ing adequately tight closures when carefully applied, have involved somewhatcompli cated procedure in applyino them. Screw topsfall in this category. l f well fittedand thoroughly screwed down, they will form satisfactorily tight closures. But the aver-' 0 age sales person, in the haste of retailtrade, is likely not to seat the top fully, to leave it only resting upon the jar mouth or partially screwed down so thattight closure is lacking. Furthermore, those covers which 46 are easily and quickly applied and removed (e. g., without being screwed on or oil) do not close the jars adequately ii carelessly applied The present invention aims to avoid these 5o objections, in a cover which may be easily applied and removed.

- Referring to the accompanying drawings,

the illustrative'embodiment of the invention includes a cover i applied to the mouth ms of a jar or the like.

and held against ionv Disregarding for the present the particum ARIDOR' company, or

lar fprm and material of the cover and of the ar mouth, the direct cooperation. bei tween the two is characterized by a resilient wall 6 on'one of the parts, arranged to form a. tight closure with the other part.

As shown, the resilient wall 6, carried by the top 4, is in the form ofa depending annular flange having a convert or torus-like inner surfaced, The leastYdiameter of the annular convex inner surface of the wall 6, e. g'., between the points a,, and h, Fig. 2, is slightly'less than the outside diameter of the jar mouth with which the resilient wall is intended to be engaged. With this arrangemerit, if the cover 4: is pressed down upon the jar mouth, the resilient wall will he compressed in cross section and will be made to grip the outer suriace oi the jar mouth.

From the points a and l), the convex surface 7 recedes to provide an enlarged circular opening at the lower extremity of the wall to receive the jar mouth when the top is initially applied; and also an enlarged annular space to receive the jar mouth when w the top is fully seated over the mouth of the jar.

The mater al oiiwh ch the wall is formed may be of such cons stency as to retain its normal sha "e. and atthe ,sarne,v time possess suiiicie'nt" pliability to be readily compressed,

sons to adaptitselif to the form off-the jar mouth at whatever angle the cover may he,

placed thereon.

lnthe specificemhodiment shown, the re silient wall 5 comprises a gasket of rubber or the like which maybe positioned within a depending wallportion oi the cover i,

a tudinal displacement with reference thereto or,"

. 9 adja cent its upper or inner e and v y a narrow inwardly extending annular flange ill formed on the lower or outer edge of the wall portion. 8.

The wall 6 may he provided on its outer, surface with a relatively loroad annular groove 11, thereby, producing a wall of cone; cavo-convex cross-sectional form which, in, addition to being compressible as above. mentioned, is capable also oi? heing distorted laterally when placed over the jar mouth.

It will be observed-that when thegasket is placed within the cover l, as shown, the, concave surface of the annular groove l1- on the outer suriaceoiE-the wall 6 will form an annular hollow chamber between the wall and the inner surface of the wall portion 8 of the cover to provide suflicient space for the maximum distortion or bulgin of the wall 6 of the gasket when the cover 1s placed upon the jar.

If desired, the wall 6 may be provided with an additional jar engaging surface in the form of a laterally and inwardly extending annular-flange 12, preferably at its upper or inner edge and adjacent the shoulder 9 of the cover 4.

It will be observed that when the cover and gasket in the form illustrated in the drawings, are positioned on the jar in proper ali ent therewith, as shown in Fig. 1, and in y seated over the mouth of the jar, there will be two separate areas of contact established between the gasket and the open end of the jar, i. e. where the wall 6 engages the outer annular surface of the jar mouth 5, and where the edge of the jar mouth engages the flange 12. The annular wall 6 of the gasket, by reason of its resiliency grips the outer annular surface of the jar mouth and, in addition to establishing a tight connection between the cover and jar, assists in preventing the accidental displacement of the cover. 1

To further assist in reventing the accidental displacement of the cover and to provide a more efiicient connection between the cover and jar, the neck portion of the latter may be provided with a narrow annular flange or flattened bead 13, andwhen the cover and gasket are placed over the mouth of the jar, the gasket, by reason of its pliability and resiliency, will be compressed or bulged outwardly as above described, and when the cover is pressed home will resume a position in back of the bead (see Fig. 1) thereby assisting, in a measure, the frictional contact between the gasket and jar in resisting removal of the cover, and providing additional surface for the contact of the gasket to prevent the admission of air. This also assists in holdin down the cover with a tight connection tween the flange 12 and mouth of the jar.

The H 12 in addition to providing a seat for the outer edge of the jar mouth,

tends to stiffen the inner edge of the wall 6 and prevent any possible collapsing, or withdrawal of the gasket from the cover when the latter is removed from the jar.

It will be observed that no matter how the closure is placed on the jar (see Figs. 2 and 3), a substantially air-tight connection is establ shed between the jar and closure; the pressure incidental to the mere. placing of t e closure on the jar being suflicient to to distort or compress the wall 6 of the gasket to provide contact throughout the periphery of the jar mouth.

In the use of the present invention, no

appreciable amount of time or care is required in placing the closure on the ]ar to insure a proper connection therebetween, for even though the closure be carelessly applied the jar immediately is made substantially air-tight. This is highly important and most desirable when jars or the like equipped with such closures are used as dispensing receptacles in stores, candy shops and Obviously the present invention is not.

limited to the particular embodiment thereof herein shown and described.

Having thus described my invention, I claim:
