WILLIAM DOUGLAS, OF TACOMA, WASHINGTON.

BOTTLE AND STOPPER THEREFOR.

To all whom it may concern:

Be it known that I, l/VILLIAM DOUGLAS, a citizen of the United States, residing at Tacoma, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in Bottles and Stoppers Therefor; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in bottles and stoppers therefor, and particularly to stoppers that are adapted to prevent or make extremely hard the refilling of the bottle, without destroying the stopper or bottle.

Another object in view is the provision of a bottle and stopper therefor arranged to act in conjunction with each other for preventing or substantially preventing the refilling of the bottle without mutilating or destroying the same or the stopper.

Another object in view is the provision of a bottle arranged for receiving a stopper,

and means for holding the stopper against movement, the stopper being adapted to freely permit the removal of the contents of the bottle, but to resist the forcing of liquid into the bottle.

A still further object of the invention is the provision of a bottle having a stopper provided with a plurality of tubes arranged with reciprocating valve members that permit the flowing in of liquid through the tubes when in a certain position, and prevent the flowing of liquid through the tubes when in any but that position, and a housing for protecting sai'd tubes and preventing tampering therewith.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a longitudina vertical section through the neck and part of a bottle and stopper constructed according to the present invention. Fig. 2 is a section similar to Fig. 1 showing the relation of the aperture in the valve tubes to the lip in the neck of the bottle.

' Fig. 3 is a section similar to Fig. 1 except Specification of Letters .Patent.

Application filed May 18, 1908.

Patented Apr. 19, 1910.

Serial No. 433,530.

Referring to the drawing by numerals, 1 indicates a bottle of any desired shape, and 2 the neck thereof, which may be of any desired shape exteriorly, but its interior must be either preferably straight or wider at the top than at the bottom in order to permit the insertion of the stopper hereinafter more fully described. Formed in neck 2 is a groove 3 that is adapted to receive a spring ring 1 which also engages a groove 5 forined'in casing (3 of stopper 7. The ring 1 is adapted to be placed in groove 5 and may be forced sufficiently therein to permit the insertion of the stopper 7 into the neck 2, and as the same is forced down until groove 5 comes even with groove 3, spring 4 will move over and fill groove 3 and artially fill groove 5, that is, will ex 921ml in the usual manner of a spring ring or engaging both grooves 3 and 5. This will prevent stopper 7 from being removed, unless the neck of the bottle is broken. This will usually be sufficient for holding the stopper 7 in position, but if desired I may provide the bottle 1 with a stop 8 upon which the stopper 7 may rest. The stop 8 is usually constructed in the manner of an offset or shoulder extending entirely around the neck 2 and usually there is placed a packing washer or ring 9 between the shoulder or stop 8 and the stopper 7 for forming a tight joint therebetween. If desired the ring 4: may be dispensed with and stop 8 and the stopper 7 held in by cement of any desired kind, though ordinarily the structure just set forth is preferable.

Stopper 7 is formed with a housing 6 that is provided with a plurality of apertures 10 near its upper end, and is adapted to engage or contact with packing 9 at its lower end. Positioned in the upper third or upper part of easing 6 at a reasonable distance below the apertures 10 is a filling 11 which may be made of cork, rubber or other desired material; and positioned in the lower part of easing 6 or the end opposite the apertures 10 is a second filling 11 which may be made of cork, cement or other material. These fillings are usually concave from below upward to form a well in their base. Positioned in the fillings 11" and 11 are tubes 12 and 13 that are adapted to form ways for the removal of liquid and the insertion of air. The tubes 12 and 13 are closed at the lower end but are open at the upper end. Though open at the upper end they are rounded or bent over at 1 1 and 15 re spectively so as to constrict or reduce the end of the tube, to prevent the valve members 18 and 19 from falling out of the tubes 12 and 13. Tubes 12 and 13 are also formed with apertures 16 and 17 respectively. This is arranged so that air may enter in through some of the openings 10 and pass through the tube 12 and out opening 16 into chamber 21, then through tube 13 and finally out opening 17 while liquid will pass through the same channels in the opposite direction.

Positioned in tubes 12 and 13 are auxiliary tubes or valve members 18 and 19 that are open at both ends, and are of such a size as to snugly fit the inner bores of tubes 12 and 13. These valve members are adapted to reciprocate freely in tubes 12 and 13 in order to open or close apertures 16 and 17, the apertures 16 and 17 being held closed by these valve members when the bottle is set in an upright position or held in substantially that position, but when the bottle is turned over or upside down valve members 18 and 19 are moved from covering openings 16 and 17 until they contact with the restricted or bent over portions 14: and 15. This will permit liquid to pass from opening 17, tube 13, valve member 19, through chamber 21 and thence through opening 16, and from thence out some of the openings 10. These valve members should be of such size and weight as will be sufficient to insure their movements. Valve members 18 and 19 are adapted to extend nearly the full length of their respective tubes 12 and 13 so that a very slight movement vthereof will cover the various apertures 16 and 17. The action of these valve members in closing the apertures and preventing the entrance of water depends on the contact of their lower outer circumference against the angle of the floor of the containing tubes, consequently it is essential that these valve members have a regular outline at their bases and that the tube floor be distinctly angular, not flat in relation to the wall of the tube. Water tends to enter the closed valve at the lower end of the valve members and air to make its entrance via the upper margin between the tube and the valve members. By reason of the restricted portions lt and 15 not only will the valve members 18 and 19 be prevented from moving out of their respective tubes but an instrument will be prevented from removing the same. The housing 6 is also adapted to prevent any use of tools in removing valve members 12 and 13.

The stopper 7 is adapted to be fitted into the lower end of neck 2 so that a cork or stopper 20 may be used if desired, although it will be evident that stopper 7 could be 7 positioned so that the upper end of casing 6 would be flush with the top of neck 2.

The space between fillings 11 and 11" in stopper 7 designated'chamber 21 takes the place of a reservoir and acts as an inverted unspilling ink well. chamber is acquired by the disposition and size of the tubes, the upper valve tube 12 being usually of larger or not less diameter than the lower tube 13 and this upper tube 12 protrudes not farther into the chamber 21 than is necessary to clear the upper margin of the aperture 16 in its wall. The lower tube 13 protrudes upward through the filling 11 to a distance not less than one half the diameter of the inside of that part of the stopper 7 contained in chamber 21 and the aperture 17 protrudes into the bottle cavity proper, the upper margin of aperture 17 being on a level with the lower margin of filling 11, to permit the escape of all fluid contents. The action of this chamber in preventing the inflow of liquids from without lies in the fact that liquid only can enter the chamber 21 while the valve member 18 is moved away from the aperture 16 and while the aperture 16 is facing downward consequently when a sufficient quantity 0 7 liquid has entered the chamber by reflux through valve tube 12 the aperture 16 becomes submerged and no more liquid can enter and the amount of liquid that has entered up to the submerging point of aperture 16 is insuiiicient under the disposition of the parts to reach the entrance 14 of tube 13 either in the horizontal or any other position, consequently no liquid can flow into tube 13. Should the liquid in chamber 21 be shaken into tube 13 the valve action prevents any escape into the bottle and any eiiort to open the valve in tube 13 removes the liquid back into chamber 21.

It is noticed that the escape of liquid in emptying the bottle provided with this device, is more free when the apertures 16 and 17 are in the same direction, consequently to aidin the ready removal of liquid in emptying the bottle it is usual to have some mark such as a lip 22 or elongation of the mark in the neck '2 of the bottle, this lip or elongation being in the oppositeside to the apertures 16 and 17 WVhat I claim is:

1. In a device of the class described, a bottle formed with a neck portion, a housing This action of the fixed in the neck portion, fillings arranged tion and to expose the said openings when the bottle is inverted.

2. In a device of the class described, a bottle formed with a neck portion, a housing fixed in the neck portion, fillings arranged within the housing, tubes arranged centrally and in axial alinement supported one by each of the fillings, and a valve member slidable within each of the tubes.

3. In a device of the class described, a bottle formed with a neck portion, a housin fixed in the neck portion, fillings arranged within the housing, tubes arranged centrally and in axial alinement supported one by each of the fillings, each of the said tubes having its lower end closed and its upper end open and formed with an opening in its side, and a tubular valve member slidable in each of the tubes, the said valve members being open at each end.

4. In a device of the class described, a bottle formed with a neck portion, a housing fixed within the neck portion, a partition arranged within the housing a tube arranged centrally and supported by the partition and extending therethrough, the said tube being formed with an opening in its side below the partition and with an open upper end, a tubular valve member slidable within the tube, a second partition arranged within said housing below said first mentioned partition, a tube arranged centrally of and supported by said second mentioned partition in axial alinement with said first mentioned tube, and a valve member slidable within said last mentioned tube.

5. In a device of the character described, a bottle formed with a neck portion, a housing positioned insaid neck portion, a plurality of tubes positioned centrally in said housing and in axial alinement, said tubes being formed with apertures near the ends thereof, tubular members positioned in said tubes and adapted to reciprocate therein, said tubular members being adapted to close said apertures when said bottle is in an upright position and to permit matter to flow through said apertures when said bottle is inverted, and means for holding said tubes in said housing.

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