2 Claims.

This invention relates to new and useful improvements in non-rellable bottles, and it is among the objects thereof to provide ajvalve arrangement in the neck of a bottle whichwill permit emptying the contents from the bottle in its tilted position while preventing refilling of the bottle in any position and which shall embody means for preventing iiow of the liquid contents when the bottle is in a horizontal position.

These and other objects of the invention will become more apparent from a consideration of the accompanying drawings constituting a part hereof in which like reference characters designate like parts and in which:

Fig. 1 is a fragmentary cross-section of a bottle neck and valve mechanism embodying the principles of this invention;

Fig. 2 a similar View of a slightly modified form of the device shown in Fig. l;

Fig. 3 a fragmentary cross-sectional View of a bottle valve and neck of Fig. 1 with its axes disposed horizontally;

Fig. 4 a similar view of the bottle neck and valve in a tilted position for pouring;

Figs. 5 and 6 a cross-section and plan View respectively of the valve. cap; Y

Figs. 'l and 8V plan and crosse-sectional views respectively of the valve body;

Fig. 9 an elevational view of a ball member;

Figs. 10 and 11 plan and cross-sectional views respectively of the valve;

Figs. 12 and 13 plan and cross-sectional views respectively of an end member for the valve body;

Figs. 14 and 15 a plan and cross-sectional view respectively of a cork liner;

Figs. 16 and 17 a cross-section and elevational view respectively of a modified form of cap member; and

Fig. 18 a fragmentary view in elevation of a bottle neck embodying the valve of Fig. 2 of the drawings.

In the drawings the numeral I designates a bottle neck of somewhat larger diameter than the neck of a conventional bottle having a cylindrical inner wall 2 slightly enlarged near the end as indicated by the reference numeral 3, the outer wall of the neck being provided with a bead 4 of conventional form and a thread 5 for receiving a cap or closure 6.

The bottle neck for the different forms of valve elements of Figs. 1 and 2 is identical. Disposed within the neck I is a valve housing 1 more clearly illustrated in Figs. 7 and 8, the

exterior of which is provided with a constricted y portion 8 for receiving a cork strip 9, Figs. 14 and 15, which functions as a seal between the valve body and bottle neck. Thecork liner E may be grooved at II] to receive a tab `with printed indicia thereon to designate the brand, origin or serial number of the liquid contents or shipment or to designate the manufacturer of the bottle or both, as shown in Fig. 18. c

The interior of the valve body l is hollowV and grooved as 'shown at I I and ribs I2 are provided as tracks for the ball member I3 to permit the flow of uid around the ball through a plurality of flow passages I4, four of such passages being shown in Fig. 7. The upper endof the valve body 1 is provided with lugs i5 and a projection I6 that cooperate with the lugs I'l and wall IS of an end cap generally designated by the =nu meral I9 shown in Figs. 5 and 6, the surfaces I8 and I6 being spaced to provide a flow passage and the lugs I5 and I prevent seating of the end cap on the top of the valve body l at any portion excepting on lugs I5 and I'l. Thezend cap I9 is provided with a central hemispherical 'portion 20 to divert the flow of the fluid leaving`-passages I4 and as will be seen in Fig. 8 the top of the valve body l is concave at itsvmidportion to prevent the projection from contacting the end of the valve body. The end cap I8 Ai-s `fused to the valve body 1 at the lugporh tions only to firmly secure the two parts into an integral member.

A hollow plug 2l, Figs. 12 and 13, is adapted to be inserted in the bottom end of the valve body 'l as shown in Fig. 1, and a fiatdisk valve 22, Figs. 10 and 11, is adapted to rest on the member 2l to control the flow of liquid through the central passage 23. Valve 22 is shaped as shown in Fig. 10 so that the lugs 24 Contact the inner wall II of the valve body to center the valve on the flow passage 23 When in its closed The valve element is placed in the neck of the w bottle I after the bottle has been filled, the parts having previously been assembled as shown in When the bottle is brought to its uprightposi- Y Y tion, the Weight of the ball will again sealyalve 20 Fig. 1', the valve body beingcemented to Ythe inner wall 2 of the bottle neck. Y

In the position shown in Fig. 1 the ball I3 rests upon the valve 22 `to seal the contents of the bottle, at the same time permitting venting of any gas pressure generated in the bottle chamber. When it is desired to pour liquid from the bottle, it is tilted as shown in Fig. 4V in which position the ball I3 abuts the inner projection I 3a of the valvebody and the valve disk 22 drops away from its seat Vto permit the fluid to 'ow from passage 23 around the ball I3 through the passages formedl by theV ribs I2 and out through'passages I4 into the end cap from which Y it ows in a divergent path between the'space formed Vbythe walls I6 and I8 through the openings formed by the spacing lugs I5 and I1.

22 and if the bottle is disposed in a horizontal Vposition as shown in Fig. 3, the curvature Vofthe ribs I2 and the inner wall II of the valve body will force the ball against the disk 22 aspshown in Fig. 3, thus preventing ythe flow of fluid from the mouth of the bottle. While the force Vof the uid within the bottle is sufcient to displace ,theV valve 22 and ball I3 in the horizontal position of the bottle, the atmospheric pressure on the open side ofthe valve will hold the valvev closed as the displacement of any liquid from the interior of the bottle will reduce the pressure on' the inner side of the valve.V This is an impor- Y `tant feature of the bottle valve. Y' In the modificafrom.

A suitable closure cap- 6 may be provided for z the form of end cap shown in Figs. 2 and 18,

this being desirable to prevent exposure of the mouth of the bottle and valve to the atmosphere. While kmany Vforms of non-refillable bottles have been heretofore proposed, it is evident fromV the foregoing description of this invention that ka valve structure made in accordance therewith not only provides for the easy'pouring-of the i 'contents' of the bottle and prevents refilling of the bottle but also prevents spilling of the con-- tents when the bottle is placed in a horizontal position. Also, with the arrangement shown theY ValveV cannot be removed from the bottle neck without kdestroying the entire bottle. The valve parts, when made of porcelain, can ybe economically produced in commercial quantities so that the use of the valve will-'not materially increase Y the cost of the contents.

Although one embodiment of the invention has been herein illustrated andV described, it will be evident to those skilled in the art that Y modifications may be made in the details of construction withoutv departingy from ples` herein set forth.

Iclaimz. 1. In a'non-refillable bottle the combination with a bottleneck of a valve therefor, said valve consisting of a main body portion extending sub-` the princistantially the full length of the neck having aY Y hollow interiorY of curved and ribbed walls, an

end cap adapted to be fused to the top of the Y valve body to Vform flow passages leading to the hollow interior of the valve, a hollowend mem: ber` for the bottom ofthe valve having a restricted ow passage of lesser diameter thanthe inner wall of the valve, a flat disk seated on said end member, and a ballyfreelymovable on the interior of the valve body, the curved wall of Vthe valve body extending Ybeyond the seatV of the disk valve whereby the ball is forced against theV valve in any position of the'bottle betweenV a perpendicularV and horizontal axis. Y

2. InY a non-refillable bottle the combination with a, home neck having a. cy1indrica1 inner Y* bodyi having flow passages formed by the spac- K ing of the cap with the end surfaces of the valve Y body, a valve seat with a constricted flow passage disposedrin the lower end of the vvalve body,

'a valve disk disposedon said seat, a ball within the hollow interior of the valve body adapted to engage said valve, and a packingrmaterial'disposed around the exterior ofthe valve body extending a portion of its length and yieldingly engaging the inner wall. of the bottle neck.
