CHARLES VAN AMBURGH, OF TACOMA, WASHINGTON.

AIR-TRAP NON-REFILLABLE BOTTLE.

Application filed March 16, 1915.

To all "whom it may concern."

Be it known that 1, CHARLES VAN AM- BURGH, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of \Vashington, have invented certain new and useful Improvements in Air-Trap Non-Refillable Bottles, of which the following is a specification.

This invention aims to prevent the reuse of a bottle or like container after the same has been emptied of its contents and, furthermore, prevents the replenishing of such bottle after a portion of the liquid contents has been drawn off, thereby protecting the consumer as well as the party or concern placing a liquid upon the market under a given trade name or brand.

In accordance with this invention the bottle or like necked container is formed with a trap in its neck, an air passage extending around such trap and opening at its ends into the neck and bottom of the bottle and a filling opening in the bottom of the container which is adapted to be sealed in a manner to prevent the uncovering of such opening without rendering the bottle useless for further service.

The invention further aims to provide a bottle or like container with a trap disposed in the length of the neck thereof, such trap serving to prevent the refilling of the bottle. In this connection it is necessary to provide for the admission of air to fill the space formed by drawing off the liquid contents from the bottle.

A further purpose of the invention is the provision of a bottle or like container having an air passage formed in a side thereof and extending from a point within the neck of the bottle to a point adjacent the bottom so that air will readily flow into the bottle to replace the contents drawn therefrom.

The invention consists of the novel features, which hereinafter will be more particularly set forth illustrated in the drawings hereto attached and pointed out in the appended claims.

In the accompanying drawing;Figure l is a vertical central section of a bottle constructed in accordance with the invention; Fig. 2 is a horizontal section on the line 22 of Fig. 1; Fig. 3 is a vertical section of a flask embodying the invention; Fig. 4 is a horizontal section on the line l1 of Fig. 3.

Corresponding and like parts are referred Specification of Letters Patent.

to in the following description and indicated in all the views of the drawings by the same reference characters.

The container may be of any shape or capacity so long as it is formed with a neck. In Figs. 1 and 2 the container 1 is of circular outline and has the ordinary appearance of a bottle and is provided at one side with a passage 2 which is located wholly within the body of the bottle so as not to interfere with the usual external configuration. he passage 2 opens at its upper end within the neck 3 of the bottle, at 4, and communicates at its inner end with the bottom of the bottle, at 5. The passage 2 admits air into the bottle when drawing off the liquid contents thereof and the bottle is turned so that the air passage 2 occupies the uppermost or highest position to admit of air entering the air passage at 4 and passing into the bottle at A trap is formed in the neck of the bottle, Jreferably as a part thereof, and is adapted to be sealed by the liquid when at tempting to refill the bottle. The trap is indicated at 6 and is of S-form and ob structs the neck of the bottle. The trap may be formed in any manner and consists of an S-shaped passage formed in a partition extending across the neck of the bottle. The entrance 4 of the air passage 2 is located between the trap and the mouth of the bottle, thereby admitting of air passing into the bottle through the passage 2 when the bottle is properly positioned to draw off the liquid contents thereof. The mouth of the bottle is adapted to be sealed by means of a stopper 7 or other type of closure generally employed for sealing necked containers or receptacles of the bottle type.

A bottle or container constructed in accordance with this invention is provided in its bottom with a filling opening 8 which is adapted to be hermetically sealed in any manner so as to prevent the uncovering of the filling opening after the same has been sealed. The closure 9 for sealing the filling opening 8, may be pressed into the opening or may be cemented therein, and in the event of such closure being of metal and secured in the filling opening by crimping or in any other way, a packing 10 is placed in the filling opening so as to extend over the seal and prevent direct contact of the contents of the package or container with the closure.

The container 1 shown in Figs. 3 and 4,

is of flattened form and is of the type designated as a flask. The air passage 2 is formed in an edge of the flask and is located exterior thereto, as indicated most clearly in Fig. The air passage communicates at its upper end with the neck of the container and at its lower end with the bottom thereof in substantially the same manner as described in connection with Fig. 1. The trap 6 arranged within the neck 3 of the flask is substantially the same as the trap 6 and subserves the same purpose. The filling opening in the bottom of the flask is designated by the numeral 8 and is closed by means of a seal 9, which is protected by a packing 10.

A container embodying the invention has its neck sealed by means of a closure 7 and is inverted with the filling opening 8 uppermost when filling the same with the liquid contents to be marketed. After the container has been tilled the opening 8 sealed in such a manner as to prevent the uncovering of the filling opening without mutilating or otherwise rendering the container unserviceable for further use. \Vhen it is required to draw oil the contents of the bottle or other receptacle or container, the closure 7 is removed and the bottle or container is tilted in the manner well known to admit of pouring off the contents thereof. Care must be taken to hold the bottle in such position that the air passage uppermost or on the high side so that air may pass into and through the air passage into the bottom of the bottle while the liquid contents flows oil through the lower portion of the neck without interfering with the inflow of air through the neck of the bottle into the passage 2. When the bottle is in upright position and an attempt is made to replenish the same the lower end of the air passage is sealed and the liquid is trapped in the S or tortuous passage constituting the trap, hence it is practically impossible to refill the bottle. it will be understood from the foregoing taken in connection with the accompanying drawing that the invention provides a simple and etiective way for preventing the reuse of a bottle or similar package or con tainer and, furthermore, that the trap in the neck and also the air passage may be formed in any manner so long as they accomplish the ends set forth herein, therefore it is to be understood that within the purview of the invention as claimed changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is:

A bottle having a partition formed in its neck as a part thereof, and having a trapped passage in said partition, said bottle having a portion along a side of the body and neck thereof made thick and having an air passage in said thickened portion opening at its inner end within the bottle near the bottom thereof and at its outer end within the neck between the trapped partition and the mouth and adapted to be closed at its outer end by the cork used for sealing the bottle.

In testimony whereof I aflix my signature in presence of two witnesses.
