Application April 7, 1943, "Serial No. 482,079-

2 Claims. (Cl. 21540) This invention appertains to bottle and jar stoppers and more particularly to a reuseable closure for effectively sealing a bottle or other container irrespective of any internal pressure therein.

Much difficulty is now being experienced in tightly sealing bottles and other containers due to the scarcity of war critical materials, such as I metals, and it is therefore one of the primary objects of my invention to provide a novel stopper or closure, which can be formed from non-critical war materials, (such as glass, plastic and the like) for locking engagement with the bottle or other container.

Another salient object of my invention is to provide a bottle stopper or jar closure, in which the stopper or other closure and the bottle or jar are provided with like wide, mating, sealing and closure therefor constructed with my invention.

Figure 3 is a top, plan view of the jar closure.

Figure 4 is a detail, fragmentary, perspective view of a tool which can be utilized for opening and closing the fruit jar.

Referring to the drawing in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter B generally indicates a bottle, and S my novel. stopper therefor. I

The bottle B can be of any desired size, shape or character, and as illustrated the same includes a neck 5 having the usual annular head or lip 6 onits upper end. In accordance with my invention the interior of the neck at its upper end faces with cooperating means in the stopper and 3 bottle, orclosure and jar, for drawing said faces into intimate sealing engagement, whereby loss.

of the contents due to leakage or spoilage is prevented.

A further important object of my invention is to provide a bottle or jar neck having a reversely curved stopper seat extending from the lip of the bottle or jar inwardly into the neck a material distance and a stopper adapted to fit in said neck having its outer surface shaped to stopper consists of a solid circular body [I having seat when the stopper is inserted in the neck and turned a portion of a revolution.

A still further important object of my invention is to provide a bottle stopper or jar closure of the above character whichis durable and efficient in use, one that is simple and easy to manufacture, and one that can be placed upon the market at a low cost.

With these and other objects in View, the invention consists in the novel construction, ar-

rangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawing, in which drawing:

Figure 1 is a fragmentary, side elevational View, partly in section, of a bottle neck showing my novel stopper connected therewith.

Figure 1a is a fragmentary, detail, sectional view of the bottle neck illustrating one of the locking grooves formed in the stopper seat.

Figure 2 is a fragmentary, side, elevational view, partly in section, showing a preserving jar is provided witha novel seat I forthe stopper S.

As illustrated, the seat I takes substantially the fform of a reverse curve in cross section, similar to an ogee curve; Hence, in effect, the reversely curved seat I forms a continuous sealing surface fromthe upper face of the lip 6 down into the interior of the neck for a considerable distance.

By referring to Figures 1 and la, it can be seen that the seat I provides upper and lower annular shoulder seats orv surfaces 3 and 9 respectively with an intermediate sealing surface Ill.

, The stopper S; can be formed from any desired material and can be advantageously molded from glass or other desired plastic material. The

an annular peripheral bead l2 which is adapted to seat against the outer surface of the bottle lip 6. Below the annular head [2, the stopper S has formed. on its outer surface the reversely curved face l3 which corresponds identically with the seat I so that when the stopper is inserted in the neck the curved surface l3 will intimately contact with the seat I throughout its entire area. The lower face of the stopper is preferably of a convex form. r e

The curved face l3 of the stopper has formed thereon at diametrio opposite. points radially extending locking cam lugs I4. It is to be noted that the upper faces of the lugs 14 are inclined or of a wedge shape.

v The interior of the bottle neck is provided at diametric opposite pointswith bayonet slots in accordance Attention is called to,

the stopper will be held on its seat by the engagement of the cam or wedge lugs I4 with the walls of the grooves and hence the stopper cannot be blown off of its seat by internaipressurein the. bottle.

. In Figures 1 and lo I have-shown the features of my, invention incorporated with a bottle neck jar neck with the reversely curved seat a wide, sealing surface of great area is provided and this gives a positive seal.

If preferred a sealing gasket 30 can be placed between the flange 21 of the closure C and the jar neck. If desired the gasket can take a circular shape in cross section and the lower face of the flange 21 can be provided with an annular groove to receive the gasket.

For convenience in turning the closure C, the same can be provided with a cross shaped depressiorrill and a tool 32 having a cross shaped head 33. can beprovided- The head 33 can be inserted in the depression 3! and upon rotation of the tool the closure can be conveniently turned in either direction;

I From the foregoing description, it can be seen and stopper and obviously the various features of my invention can be incorporated with various types of closures for other containers. In Figures 2 and 3 I have shown the principles of my invention utilized in a fruit or similar jar. Re-

ferring to these figures theflruit jar is indicated by the reference character. J and my novel. closure by the reference character C.

The jar J includes a body 20 of any preferred size and configuration having the neck 2! on its. upper end. The interior of. the neck is provided with the reversely curvedv seatZZ and. this seat is of the same shape and configuration as the seat 'I previously described and hence upper and lower annular shoulder seats 23 and 24 are respectively provided with an. intermediate curved face therebetween. The inner surface of the neck can be. provided, atquarters, with the bayonet slots orgrooves 25 and these slots or grooves 25 are formedbetween the seats 23 and The jar closure C includes a body 26 having formed on its upper end the annular outstanding flange 21 which is adapted to extend over the seat. 23 and over the outer lipof the neck. The body of the stopper C, below the flange, has its outer surface. provided with the reversely curved face 28 which corresponds directly with the shape of the curved seat 22 forv intimate sealing engagement therewith. The bottom surface .of the stopper 0- is also preferably of a convex form.

Thebody of the. closure below the flange 21 is provided, at quarters, with radiallyv extending cam orv wedge shapedlocking lugs 29 which are adapted to be inserted in the bayonet slots or rooves 25.

In. use of my closure the jar is filled in any approved. manner after which the closure 0 is inserted in the jar neck with the cam or wedge shaped lugs. inserted in the bayonet slots. The closure is now given a slight turn so as to move the wedge shaped lugs in the right-angular portions. of the bayonet slots or grooves. and the contacting of the wedge or cam lugs with the walls of the grooves will forcibly bring down the closure within thejar neck so that the curved seal.- ing.v face 28 thereof will be brought into tight engagement with the curved seat 22 in-the jar.

By forming the stopper and. closure in the manner described and by providing the bottle and that I have provided an exceptionally simple and durable closure which can be effectively formed from non-critical war materials. Obviously the stoppers and closurescan be continuously reused and as the same are formed tromglass or plastic, cleaning thereof is. easily effected.

Changes in details. may be made. without departing from the spirit or the scope of my in.-

vention,. but what I'claimas new is;

l. The combination with. acontainer having a neck provided with an interior. reversely curved closure seat, said seat extending. from the outer surface ofv the neckinto the. interior of said neck and defining an. upper annular. shoulder seat and a lowerv annular shoulder seat. of. less. diameter than the upper annular shoulder seat and an intermediate connecting curved surface, of a closure removably fitted in the neck. having a curved surface shaped to correspond to said seat for contact. therewith, said closure and neck having cooperating cam Iugsand grooves for drawing the curved surface of. the closure into tightseali'ng contact with the upper and lower shoulder seats and the intermediate curved surface of. the

neckv upon the insertion' of. the cam lugs in the grooves and the turning of the closure.

2. The combination with a bottle having a neck provided with anannular lip and an interior annular seat extending from said .lip into the neck, said seat: having a reverse. curve in cross section. defining. upper andlower annular shoulder seats andan. intermediate connecting curved surface, of a stopper .insertable in said neck including a body provided with an annular bead and a reversely curved annular surface below said bead. for contacting with the interior annular seat, said bead engaging the outer face of the lip, the seat having formed therein in the intermediate curved surface between the upper and lower shoulder seats L-shaped grooves, and radially extending cam lugs formed on the curved surface of the stopper for insertion in said grooves, whereby upon turning of the stopper and movement of the logs in the lower ends of the grooves, the curved surface of, the. stopper will be drawn into intimate sealing engagement with the upper and lower shoulder seats and the intermediate. curved surfacev andthe head into engagement with the lip.
