DI SPENS ING DEVICE Patented Oct. 1, 1935 UNITED STATES PATENT OFFICE 17 Claims.

My invention relates to dispensing devices adapted to dispense liquid or other freely flowing materials in predetermined amounts from a bottle or other frangible container mounted thereupon.

More particularly my invention relates to such a dispensing device which is provided with means for detachably securing the same to a suitable support, whereby the device may be inverted and secured to the neck of a filled container in such a manner as to prevent separation thereof, without breaking the neck of the container.

My invention relates further to valve means within the frangible neck of a container for normally sealing the contents of the container, said valve means being operable by means for securing the neck of the container to the dispensing device for opening the valve as the annular end of the neck is brought into sealing engagement with a leakproof gasket in the dis pensing device.

A further object of my invention is the provision of valve means wholly within the frangible neck of a filled container for normally sealing the same, said valve means being operable to effect communication through the valve to the interior of the container and to break the neck of the container when operated to close the valve.

A still further object of my invention is the provision of socket means on a dispensing device for receiving and supporting the frangible neck of a container, said socket means and neck being provided with cooperating engaging means for drawing and securing the one within the other upon relative rotation; for establishing communication through normally closed sealing means between the container and dispensing device upon such relative rotation, and for preventing the closing of such sealing means and separation of the container from the socket of the dispensing device, upon further relative rotation, without breaking the neck of the container.

In order that my invention may be better understood, reference will now be had to the accompanying drawings, wherein:--

Fig. 8 is a perspective view of the sealing valve as it would appear in the neck of a filled container, the container neck being indicated in dotted lines. v 30 According to this invention it is desirable that the measuring and dispensing device, indicated broadly as A, be formed with a bracket 5 having a tapered base portion 6. As shown in Fig. 1 the base portion 6 is adapted to be removably 35 supported in an angularly flanged holder 7 secured to a vertical panel at the rear edge of a shelved member indicated at B so as to position the dispensing device A with its outlet spout 8 overhanging the shelf. 40

A strap-like member 9 is shown secured intermediate its free ends to the vertical panel above the flanged holder 1, the free ends of the strap being bent to extend in parallel planes and apertured to receive the shackle of a padlock or other 45 looking member ID. a As shown in Fig. 1 the strap member is preferably shaped to surround and fit within an annular groove in the body portion of a bottle-like container 0 so that the container C is firmly held by the strap against unauthor- 5O ized or accidental movement relative to the dispensing device A for reasons which will be more fully explained hereinafter. To facilitate the operation of locking the container to the shelved member B I provide one of the apertured ends 55 7 end of the strap to hold the ends together with I the container.

their apertures in registration for the ready insertion of a locking shackle as above explained.

The container C may take the form of a glass bottle having a neck i2. By reference to Fig. 3

it will be noted that the frangible neck I2 is formed with a relatively thick cylindrical end portion 53 and a weakened portion adjoining the cylindrical end portion. The weakened portion may take the form of an annular groove i and the cylindrical portion adjacent the groove may be further strengthened by an annular rib it to insure that breaking or fracturing of the neck will occur inwardly of the cylindrical end i3 to facilitate removal of a fractured end portion l3 from the socket I6 of the dispensing device A, all as will be hereinafter more fully explained.

At the lip or outer" end portion of thecylindrical neck i3, is formed a plurality of circumferentially spaced lugs H, each having an inclined inner edge, and the cylindrical bore of the socket H5 is provided with cooperating internal lugs it. The lugs 68 are spaced to receive the in clined edges of the lugs i! beneath their oppositely inclined facesto draw the neck portion l3 within the socket it to seating .and sealing engagement with an annular gasket 19 at the base of the socket upon relative rotation of the container C and socket of the dispensing device A. r

The parts above defined function to secure the container and dispensing device together so that the unit may be supported from the shelved member B in the manner illustrated in Fig. 1.

To provide means for normally closing and sealing the contents of a filled container, which means will be automatically operable to open communication between the container and the dispensing device when attached in the manner described and thereafter. prevent the closing of such sealing means and separation of the container from the dispensing device without mu tilating the container, I provide a neck sealing valve such as is illustrated in Figs. 4 to 8, inclusive.

This valve comprises one-way rotatable disklike members 2i and 22, each having two ports which are eccentrically disposed on opposite sides of a transverse web portion, the adjacent faces of the disk members being coated or otherwise provided with a sealing material indicated at 23, to prevent leakage between the members when disposed in abutting relation with their ports out of registration as illustrated in Fig. 8.

- The valve member 22 is rotatably mounted in the cylindrical bore of the frangible container neck i2, immediately behind the weakening groove it and is there held against axial movement by a shoulder 26 in the bore and the retaining member ii of the valve which is threaded 'into the neck to abut one side of the valve member 22. When thus assembled in the neck of a filled container by the use of an'assembling tool (not shown) the slots of the key- ways 25 and 26 are aligned by the tool which shifts the ports of the abutting valve members 2i and 22 out of registration to close and seal the contents of Reverse rotation of the retaining valve member 2! in the threaded hereof the neck is thereafter prevented through the wedging or clutching actionbf oppositely disposed spring 7 pressed balls 21 and 28 whichareinterposed between the threaded wall of the neck and eccentric grooves 29 and 30 formed in the peripheral surface of the valve member.

Disposed within the base of the socket 56, of the slots of the key- ways 25 and 23 in the transverse webs of the valve members 2i and 22. The cylindrical end portion [3 of the container neck I2 is thus centered and guided into the bore of the socket member 96, the lugs H on the neck passing between and beyond the lugs 18 in the socket.

The dispensing device may now be rotated on the neck I2 to bring the oppositely inclined faces of the lugs H and i8 into engagement which forces the lip edge of the neck firmly against the gasket it] at the base of the socket.

During this operation the key 33 is passed through the ported retaining valve member 2| and into the key-way 26 of the valve member 22 so that upon such relative rotation of the container and dispensing device, the valve member 22 is turned relative to its retaining member 25, bringing their ports into registration. The contents of the container C may now flow freely through the open sealing valve in the container neck into the chamber 34 of the measuring valve 35 in the body of the dispensing device A, as clearly shown in Fig. 4.

Reverse rotation of the container relative to the dispensing device to disengage the inclined 7 connecting lugs i! on the container neck from under the lugs l8 in the socket 5 3, without breaking the frangible neck, is therefore prevented by means now to be described.

The peripheral surface of the rotatable valve member 22 is formed on opposite sides with circumferentially extending, eccentric grooves 3t and 31, in each of which is freely mounted spring pressed balls 38 and 39. .By reference to Figs. 5

and 6 it will be seen that the balls 38 and 39 are retained within the grooves 36 and 31 by contact with the surrounding inner cylindrical wall of the frangible neck l2, immediately behind the weakening groove l4 formed in the outer surface of the neck. While the construction just defined will permit free rotation of the valve member 22 in one direction, rotation in the opposite direction will bring the eccentric surfaces of the grooves beneath the. balls 38 and 39, forcing the balls radially through the weakened portion of the frangible neck and destroying the container for further use, after separation from the dis pensing device. 7

It will be observed from the showings in Fig. 4

that upon rotation of the chambered valve 35 in to the other. The dispensing device is then rotated relative to the container. to disengage the connecting lugs I1 and I3 and align the key- way slots 25 and 26 of the valve members 2| and 22 so that the then fractured neck of the frangible container may be readily removed from the socket l6 of the dispensing device.

While it is possible with the construction of sealing valve herein described to manually rotate the disk valve member 22 relative to the ported retaining member 2| within the neck l2 of a container C apart from the dispensing device A, through the use of a specially constructed key (not shown) and thus open the valve by bringing its ports into registration, further rotation of the valve member 22 in the same direction to close the valve is prevented by engagement of the lug 40 on the disk 22, with a shoulder at the end of an arcuate groove Al in the adjacent face of the retaining valve member 2 I. Rotation of the valve member 22 in the opposite direction to close the valve, as heretofore explained, is prevented without fracturing the neck l2 and thus destroying the container C for further uses.

It will therefore be seen that I have provided means which may be operated automatically in conjunction with the dispensing device A, or manually apart from the dispensing device, to open the valve in the neck of a container C, but in each case, however, the means may not thereafter be operated to close the valve without breaking the neck of the container.

It Will be further noted that in the event the sealing valve of a container C has been manually opened, as above described, for pouring out its contents and possibly refilling the container, that it will thereafter be impossible to attach the container to the socket N3 of the dispensing device A as the slots of the key- ways 25 and 26 of the valve members 2! and 22 will be out of registration, preventing entrance of the key 33 into the valve member 22.

From the foregoing it will be seen that I have provided an improved dispensing means and container for use therewith, the construction and arrangement of parts being such as to readily adapt the device for use in dispensing beverages in measured quantities from a sealed container, without requiring opening of the seal prior to connecting the container to the dispensing means, and which will function to destroy the container for further uses when disconnecting the same from the dispensing means or otherwise attempting to close the sealing means thereof.
