BOTTLE-STOPPER.

Specification oifl'Letters Patent.

Application filed January 2, 1912. seriai No. 568,879.

Be it. known that I, Unia/iin G. Gamin. a citizen of the United States, residingY :it Burlington, in the county ot Chittenden and State of Verniont, have invented certain. new and useful `linprovenients in Bottle- Stoppers, of which the following is a speci# fication, reference being had to the accompanying drawings.

This invention relates to bottle stoppers and more. particularly to an improved type of stopper for bottles containingI effervescent `liquids.

The main object of 'this invention to provide a stopper means for bottles intended for beers, ciders, etc., which can be placed in position without the lnecessity of using powerful and expensive material for the purpose.

Another object of this invent-.ion is to have the stopper arranged so that it can be manip factored at a minimum cost, and so that. it can be placed in p'osition quickly and without diiiciilty, by hand.

Other objects of this invent-ion 4will become apparent as it is more fully set forth.

The ordinary stopper for beer bottles and the like has to be placed in position by means ofy powerful and expensive machinA ery, Wliici very often breaksl the bottle andV spoils the liquid therein. An operator is usually required to take care ot' this machinery, which adds to the cost of stoppen is Y the bottles. This invention avoids the ii i of such machinery, and eliminates the neifcssity of such an operator.

The stopper consists of a roundA piece of cardboard rendered impervious to moisture l@ .,...riiifr oi paraffin. This is vii'ipcd into the. `neck of the bottle ter 'which it is intended and catches in the grooy` iptovided therein, the pressure of' gases Within the bottle act. upon it.

@rn the accompanying drawings which illustrate by Way of example an embodiment ol this invent-ion, Figure l represents a sectional View through the neck of the bottle emb dyingA this invention, and provided with a stopper of the kind referred to. 2 is a detail ofa stopper embodying is invention, and Fig. 3 is a sectional view through the stopper.

Similar reference characters refer to similar parts throughout the drawings.

Referring to the drawing, the numeral l designates the neck of the bottle which is latter will project inwardly to a greater extent than the upper Wall and produce an upwardly facingr ledge f2.

The stopper which is designed for use4 in the. bottle, is preferably constructed of some pliable substance such :is cardboard. which is stamped out to torni the structure illus trated in detail in Figs. l and 23, the same includiingIr a dishcd body portion with its con vexed 4side facing downi'vardly and a riiu portion 4 which extends entirely around the dished body portion of the stopper and pro jects upwardly and outwardly therefrom at a. well defined angle thereto. Ordinarily this `form will be given to the stamped cut piece of card-board by an ordinary stamp,l so that no special tools are usually needed for thisl purpose of giving the stopper the form in question. After the stopper has been cut out, it is suitably treated so as render it impervious to moisture. This is preferably done by coat ingrr the saine with paratlin. rlhe stopper. is then placed in the bottle 'by droppingr it into the neck thereof, with the conyeXed side downwardly disposed. This `can be readily done by the hand. The pressure Patented Sept. 24, 1912.

of. the rases Within the bottles tends to press upwardly on the conrexed stopper and to tin-fi it inside out, as it were. This action increuses the diameter of the stopper slightly .nu muses the same to extend into the V- shaped slot 3, and more securely close the opening in the bottle. The provision of ,the paratlin on the edges of the stopper tends to make a better 'fitting for the stopper as well as rendering the same impervious to the liquid within the bottle.

The bottle is opened by inserting a' knife or sharp point-ed instrument into the neck of the bottle and piercing through the stopper. It can be then readily removed. Thus it can be seen thatvthe arrangement While being very simple, has many advantages Which the ordinary type of stopper does not anticipate. The stopper is cheap, can be quickly and cheaply installed, and can be quickly taken ont of the bottle when it is desired tol open the same, and it tends 'sure 'within lthe same increases.

It is to be noted that the recess 3 Ahas its upper wall terminating outside ofthe plane of the inner Vedge of the lower wall and that the interior wall of the' mouth of the bottle from the recess 3 upwardly. is outwardly beveled in all directions leading to the recess. The dished body port-ion of the stopper 5 is of a diameter equal to the main interior wall of the bottle neck, where it merges into the lower wall or ledge 2 ot the recess 3 and that the diameter of the entire stopper, including its angularly disposed and upwardly and outwardly inclined rim 4, 'is initially or normally slightly less than theextreme diameter of the recess. Thus, the stopper may be easily inserted in place when it is thrust into the beveled mouth of the bottle and will seat itself on the ledge `2 with the rim 4 sprung into the recess 3. The action ot' seating the stopper' is facilitated, o wing to the `fact that the upper wall of the recess 3 is at `its inner circumference ot greater diameter' than the inner circumference of the lower wall, while at the same v spread out t-osome extent sol as to eftectuv time, this disposition or formation of said wallsl 1n connection with the run 4f of the stopper 5 in n0 Wise detracts trom the se curity of the stopper, owing to the factthat when the pressure Vwithin the bottle acts upon the convexed lower tace of the body portion ofthe stopper 5, the rim 4 will tend to move upwardly in the recess and will be forced by the upper Wall of the recess to 'rally resist any tendency toward dislodgf ment. i Having thus described this invention, what. is claimed is A bottle provided in its neck and near the rim edge thereof with a circular recess, the

walls of which project. outwardly in an up-A wardly inclined direction, the. inner circumference of the upper wall bein-g (if-greater diameter than the inner circumference ot the lower wall andthe interior wall of the bottle neck being beveled outwardly in all directions from the upper wall of the recess to the rim edge of the bottle, and a stopper' of pliable material embodying a dishe'd body portion with its convexed side facing downwardly and a rim extending around the body portion and angularly disposed in re-l lation thereto. and projecting upwardly and outwardly therefrom, the normal diameter.A

of the body portion being equal to the diameter of the interior circumference of the bot'- tcm wall of the recess and the normal diameter of the entire'stopper including its rim being normally less than the eXtreme diameter of the recess, the body portion ot the stopper fitting on the ledge formed by the bottom wall of the recess and the rim of the stopper engaging the upper wall of the recess, as and for the purpose set forth.

In testimony whereof I hereunto aix my signature in the presenceoftwo witnesses.
