BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 369,332, dated September 6, 1887.

Application filed May 25,1886. Serial No. 203,205.

To all whom t may concern.-

Be it known that I, GUsTAvUs A. GEssNER, of Fremont, in the county of Sandusky and State of Ohio, have invented certain new and useful Bottle-Stopping Mechanism, of which the following is a specificatiomreferenco being had to the accompanying drawings.

The object of my invention is to provide an improved stopper mechanism of that class adapted to be applied generally to jars Aand bottles as ordinarily made with a lip or annular flange or projection around the top of the neck at the mouth of the bottle, so that thelip in all cases shall serve as a stop or bearing to resist or counteract the force applied to press the stopper down to place for sealing the bottle. I provide, as has heretofore been done Vby the use of this class of bottle-Stoppers, for

forcing the cap or stopper' down to placein or over the mouth of the bottle perpendicularly without rotating it. I thus avoid injury to the stopper-packing, which, it is well understood, is liable to result from rotary motion of the cap or stopper while being forced down to place.

In the accompanying drawings, illustrating my improvements, Figure l is a side view of the upper part of a bottle with my improvements applied. Fig. 2 is a diametrical section of the same. Fig. 3 is a view of the rotary ring, and Fig. 4 is a similar View showing a modification.

Referring to the letters upon the drawings, A indicates an ordinary jar or bottle having the usual annular lip, iiauge, or projection, B, around the mouth ol' its neck.

O indicates a loose or rotary ring iitting around the neck beneath, and bearing by its upper edge against the lip B, and provided with thumb-lugs D or the like for turning it. It may be made of one piece of plate metal bent and united at its ends,or of two semicircular pieces united. In this instance this ring is provided with screw-thread sections E, between which are spaces or plain surfaces I1 rlhe cap or stopper G has corresponding screw-thread sections, G', and spaces or plain surfaces H between them. I show in the drawings two formsone in which there are four sections of a single screw-thread, preferably of large size, on the ring and cap, and in the other of which there is an interrupted (No model.)

thread, which, without the interruptions or cut-away portions, would constitute a single continuous thread composed of several convolutions. These forms of brokenor interrupted threads enable the cap to be put in place over the ring readily, so that by turning the ring the cap will be drawn tightly over the mouth of the bottle to seal it, andthe strain or downward pressure will be evenly distributed, so as to bring the cap down truly to place and form a perfect seal.

I do not claim that this plan of using several separated sections of threads for slipping together and then uniting two parts by screwconnection is broadly new, as itis common in hose-couplings, &c.; but I adopt it because it is useful in the species of bottle stopping mechanism to which my improvements relate,where a rotary ring is employed to force down the cap. In this class of Stoppers for bottles, jars, &c., it has been usual to employ rubber packing and paratline packing separately; but these materials have not been used together in such a way as to effect a perfect seal, and at the same time prevent the con'- tents of the scaled vessels from coming in contact with the rubber, and also to prevent the rubber from being exposed to the atmosphere, which causes its deterioration and decay.

In my device I provide in the interior of the top of the cap an annular recess, K, into which I insert a neatly-fitting rubber ring, Il. Over this ring and within the annular groove or recess I place a close-tting parafue-paper disk, M. The resultis that when the cap is brought down pcrpcndicularly to place without turning a perfect seal is formed, and only the paraffine surface can be brought in contact with the contents ol" the bottle or vessel, and at the same time the rubber packing is thoroughly protected from exposure to the atmosphere. The compression of the rubber between the cap and circular lip or edge of the bottle will cause the periphery of the rubber within the groove of the cap to thicken up, so that the margin of the parafiiue disk will be pressed downward against the annular shoulder or ledge N, forming the bottom part of the annular recess of the cap, so as to seal the rubber itself tightly within the groove in the cap and exclude the atmosphere. This IOC l form of .stopping mechanism is designed for wide-mouthed bottles or jars intended to be used for containers of fruit, snuff, tobacco, confectionery, chemicals, powdered drugs, baking-powder, dac.; also, as a substitute for ground-glass stoppers for druggists7 wideinouthed shelf furniture. A positive and equal traction at all points of the inner surface of the cap is secured with the exertion of much less force than is required for other sealers.

rThe working of this species of stopper is so simple and certain that any child can successfully manipulate it.

The employment of combined protective rubber and parafne-paper seal in my bottlecap increases the durability of the rubber, prevents the contents of the bottle or jar to which it may be applied from coming in contact with any metailic surface, thereby obviating destructive corrosion of the metallic parts of the cap and the consequent contamination of the contents of such containers. The rubber or paraiiine disks may be removed independently of each other as occasion may require.

I secure the perfect adaptation 0I' the rubber packing to any unevenness of the upper surface of the lip of the bottle or jar by eonlining the rubber ring in the annular recess immediately over the lip of the bottle, forcing the rubber to distribute. itself around the circle over the lip. I thus get a certain and perfect seal with more ease and convenience than any other with which I am acquainted. The ring can be turned Without a spanner or wrench by the thumb and forefinger, either for sealing or unsealing.

The interposition of the paraffine-paper disk between the rubber band or disk and lip of the bottle or jar effectually prevents the rubber from adhering to the glass, as is the case with many forms of self-Sealers, and which greatly increases the difficulty of opening or unsealing after jars or bottles have been sealed for a long period.

The ring and cap of my device in either of the forms shown may be made entirely by stamping'out thin metal, so that they will be inexpensive. The ring is generally made in two parts and secured together in any usual and desired manner, the points of junction forming thumb-lugs for conveniently rotating the ring to seal and unseal the vessel.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

A bottle-stopping device comprising a cap formed with an annular recess, a rubber packing seated in said recess, and a disk of parafne closely fitting the interior of the cap and covering the rubber packing, substantially as set forth.

In testimony whereof I have hereunto subscribed my name.
