1 Claim.

This invention relates to a non-removable and non-rellable bottle closure. Heretofore various forms of non-rellable bottle closures have been devised, which have in the most part been so 5 constructed that they could be removed relatively easily, or else tampered with, so that the bottle could be easily refilled. In addition, most of them are rather complicated and expensive, which is, of course, objectionable. With such obstacles in mind, it is an object of this invention to provide a closure of the character referred to which will effectively prevent any refilling of the bottle on which it is used, and which is tamper-proof and at the same time adapted to permit the contents of the bottle to be easily and quickly poured.

Another object is to provide a bottle valve or closure of this type which is adapted to be securely aiiXed with ease to the neck of a bottle and in such a manner that it can not be removed without the bottle to which it is attached being destroyed.

A further object is to provide a closure of this nature which is both pleasing to look at and relatively inexpensive to manufacture and apply to a bottle.

These and various other objects as well as the various other novel features and advantages of the invention will be apparent when the following detailed description is read in conjunction with the accompanying drawing, of which Fig. 1

is a vertical section taken through a bottle closure constructed in accordance with the invention; Fig. 2 an elevational View of the closure illustrated in Fig. 1; and Fig. 3 a horizontal section taken on the line III- III of Fig. 1.

Referring in detail to the drawing, the numeral l designates the neck of an ordinary bottle provided with a cap-engaging thread 2. Onto this thread in accordance with the invention there is secured an internally threaded dome-like shell 3 which is provided with a threaded orifice 4 at its upper end and adapted to 'lt somewhat loosely on the thread 2 of the bottle, being provided with a sufliciently larger diameter at its threaded portion than the neck of the bottle to afford a small clearance between the two.

For positively securing this dome or Cover 3 onto the neck of the bottle the space between its thread and that of the bottle is filled with some suitable cement or adhesive of a permanent nonsoluble character. This may be accomplished in various ways, but to facilitate such operation and at the same time allow the lower end of the shell to be abutted firmly against a shoulder 5 provided for such purpose on the bottle so as to form 1934, serial No. 729,839

a tight-fitting seal, a hole 6 is drilled or otherwise formed in the side of the shell through which the cement can be poured into the assembly after the shell is screwed onto the bottle.

At the upper end of the bottle engaging thread 4 on the shell 3 there is provided an internal shoulder I between which and the top of the bottle a washer-like yieldable gasket 8 made of cork or any suitable material is placed to form a seal between the shell and the bottle, and also to form a seat for a valve 9 located in a chamber II provided in the dome of the shell. As shown in Fig. 1, the gasket 8 projects inwardly over the mouth of the bottle a small distance to receive the valve, although the bottle itself may be constructed for this purpose.

The valve 9 comprises a small disc which is made flat on its under surface so as to seat rmly on the gasket 8 by gravity, and provided with a diameter which is suiiciently less than the diameter of the interior of the shell 3 to permit the contents of the bottle to ilow past it readily as well as the air bubbles which replace the contents as the bottle is emptied. However, it is not so small that it will not in all positions cover the opening I2 in the gasket 8.

On the upper surface of the valve and about its periphery there is spaced a plurality of upwardly projecting lugs I3 which engage the roof of the chamber I I and space the valve sufliciently therefrom when the bottle is in pouring position to allow its contents and the incoming air bubbles to flow freely past it. To further facilitate the rapid emptying of the bottle the dome portion of the shell 3 is made relatively long so that the valve chamber II will afford free and roomy movement of the valve as well as the liquid and air, and the roof of the chamber is preferably tapered into the opening in the shell to eliminate as much as possible obstruction to the ow.

While a cork or any suitable stopper may be employed to close the opening in the shell 3, a screw cap I4 is preferably employed for this purpose, being engaged on the threads 4 on the exterior of the shell.

As will be appreciated by those skilled in the art, the parts of the assembly comprising this invention may be made of any suitable material. However, porcelain or a transparent glass is recommended for reasons of economy and appearance, and a feature of the invention is that the cement can be put on in liquid form when the bottle is lled and allowed to set while the bottle is in storage or being shipped. Hence, no delay in the attachment of the closure need be experienced. At the same time a permanent connection is made.

According to the provisions of the patent statutes, We have explained the principles and mode of operation of our invention, and have illustrated and described what we now consider to represent its best embodiment. However, we desire to have it understood that, within the scope of the appanded claim the invention may be practiced otherwise than as specically illustrated and described.

We claim:

A non rellable bottle closure comprising a bottle neck provided with a. helical thread, a dome shaped covering shell having a pouring spout at its upper end and a threaded skirt at its lower end threadably secured to said bottle neck and xedly attached thereto by a layer of cement disposed between said skirt and the exterior of said neck, an inwardly projecting shoulder in said shell extending over the mouth of said bottle neck above the threads at the end thereon, a hollow Washer type gasket tted between said shoulder and the mouth of said neck, a disk shaped valve of lesser diameter than the interior of said shell seated by gravity on said gasket above the opening therein, a plurality of spaced upwardly projecting bosses on the upper side of said valve for preventing it closing the spout opening in the shell when the assembly is inverted, and means of closing said spout.
