1 Claim.

My invention consists in a new and useful irnprovement in bottle Stoppers and is designed to provide a device for application to an ordinary beverage bottle whereby the bottle is rendered non-rellable. The particularly novel and useful features of my improved stopper are the means which I provide for attaching the device to the neck of an ordinary bottle so that removal therefrom is effectually prevented, and the provision of a plurality of radially disposed longitudinal conduits for the passage of air and liquid, to eiectively break the vacuum when the valve of the device opens for emission of liquid from the bottle. These conduits are provided by the novel structure of a pail` of concentric shells associated with a freely oating gravity actuated valve disc designed to permit egress of liquid from the bottle and prevent ingress of liquid thereto.

While I have illustrated in the drawings led herewith and have hereinafter fully described one speciiic embodiment of my invention, it is to be distinctly understood that I do not consider my invention limited to said specific embodiment, but refer for its scope to the claim appended hereto.

In the drawings:

Fig. 1 is a vertical section of the upper portion and neck of a bottle provided with my improved stopper.

Fig. 2 is a vertical section similar to Fig. 1, showing the parts in position to allow emission of liquid from the bottle.

Fig. 3 is an enlarged horizontal section on the line 3--3 of Fig. 1.

As illustrated in the drawings, my improved stopper has a shell S designed for insertion into the neck N of the bottle B. This shell S is provided near its top with a pair of circumferential shoulders I and 2 forming an annular groove 3 therebetween in which is mounted a resilient gasket 4 of any suitable material adapted to effect an air-tight joint with the inner wall 5 of the neck N, when the stopper is inserted therein. I provide a cap C having a depending sleeve B received in the upper end of the shell S and connected therewith by any suitable fastening means, such as rivets 1. The cap C has a depending flange 8 adapted to fit snugly about the outer Wall 9 of the neck N. The cap C is suitably threaded at III to receive thereon a threaded cover II. The shell S is formed with a reduced lower portion I2 forming the interior annular seat I3, and at its lower end with a further reduced portion I4 forming the interior annular seat I5. Suitably mounted on the portion I4 is a resilient gasket IE of any suitable material adapted to be compressed so as to pass through the neck N and then expand to contact the inner surface Il of the bottle B about the neck N. It is to be noted that the portion I4 on which the gasket I6 is mounted has a diameter designed to provide suflicient space between the portion Ill and the inner wall 5 of the neck N, for the passage of the compressed gasket I6 therethrough. Positioned in the portion I2 of the shell S, on the seat I5, is the valve seat I8 of any suitable material. Associated with this valve seat I8 is the valve disc I9 having a lower sphero-convex face 20 to coact with the annular concave face 2| of the seat I8. The disc I9 is provided on its upper face With an annular upstanding flange 22.

An inner shell S' is snugly fitted within the outer shell S, its lower end received against the seat I3. This shell S comprises a lower tubular portion 23, a frusto-conical portion 24 and a reduced upper tubular portion 25. The lower portion 23 is provided with a plurality of longitudinal concavities 26 forming conduits between the shells S and S. The shell S is provided in its lower end with a frusto-conical bale 2l mounted on the lower end of the tubular portion 23 by straps 2S, thereby forming arcuate slots 28 between the outer rim of the baille 2l and the portion 23, and a central orifice 30.

When the shell S has been positioned in the shell S, seated on the seat I3, the shell S may be tapped to provide an inner boss 3l at a suitable point to prevent relative `longitudinal movement of shells S and S.

From the foregoing description of the details of construction or my improved stopper, its operation and use will be obvious.

When the bottle B has been lled with the liquid which is to be purveyed, my improved stopper is applied to the bottle B by inserting it' in tne neck N, the gasket iti being compressed to pass in the space between the portion I4 and A the wall ti. The parts are so designed and related that when the portion i4 carrying the gasket iii passes out of the neck N into the bottle B to permit the gasket I6 to expand and contact the wall I'I to prevent removal of the stopper, the cap C is properly positioned upon the upper end or the neck N and the ange 8 engages the wall 9, thereby preventing the stopper from being forced downwardly through the neck N into the bottle B. Also it is to be noted that the flange 8, acting as a skirt about the top of neck N, prevents prying up the stopper by inserting a wedge between the cap C and top of neck N.

When the bottle B is tilted (as illustrated in Fig. 2) the valve disc I9 is caused to move by gravity from the valve seat I8, thereby opening a passage for emission of liquid from the bottle B. It is to be noted (Fig. 2) that the disc I9 is received against the shell S in such a Way as to expose the inner ends of the conduits 26 and also the slots 28 and orifice 35], since only the edge of the flange 22 contacts the straps 29 on the end of the shell S. This adjustment of the parts permits ilow of air under atmospheric pressure, through the conduits 26 and ilow of the liquid through the slots 28 and orifice 30. Thus, by the novel arrangement of the parts of my improved stopper, the Vacuum, tended to be caused by the emission of the liquid from the bottle B,4 is'broken by ingress of air through the conduits 26.

It is obvious that when the bottle B is upright (as illustrated in Fig. 1), the valve disc I9 is seated upon the valve seat I8, forming a liquidproof seal to eiectually prevent ingress of liquid to the bottle B, whereby my improved stopper renders the ordinary bottle B Anon-reiillable.

Having described my invention, What I claim is: In a bottle stopper, adapted to render an ordinary bottle non-reflllable, the combination of a shell adapted to be irremovably mounted in the neck of a bottle; a valve seat mounted at the lower end of said shell; a second shell xed in said iirst shell and having longitudinal grooves on its outer surface to provide conduits between said shells; a bafe plate With a central orice mounted in the bottom of said second shell by radial straps providing arcuate slots between the edge. of the plate and the second shell; and a valve member disposed between said seat and said second shell, and having an upstanding peripheral flange.
