4 Claims, 6 Drawing Figures PATENTEU W 1 73 INVENTORS. JOHN A. MCCONNELL EVERETT W. WILLIAMSON ATTORNaS PILL DISPENSING DEVICE HAVING PLURAL CUT-OFF TRAP CHAMBER I DESCRIPTION OF THE INVENTION This invention relates to a pill dispensing device.

An'object of this invention is to provide an improved pill dispensing device which is adapted to be placed into the neck of a pill container and which is operable by the cap or closure provided to the container.

Another object of this invention is to provide an improved pill dispenser which is provided with safety features so that it is difficult to obtain a pill from the container after the cap of the container is removed.

Another object of this invention is to provide an improved pill dispenser device for a pill container, said device being provided with a pill transferring means employing a pair of rotatable members having a fixed member sandwiched therebetween, these members are provided with holes so that as the container cap is rotated, a pill entering the hole of the outer rotatable member is transferred to a hole in the fixed member and therefrom into a hole in the inner rotatable member to be removed from the pill container, this pill dispensing operation taking place as the cap of the pill container is turned through a predetermined angle.

Other and further objects of this invention will be apparent to those skilled in the art to which it relates from the following specification, claims and drawing.

In accordance with this invention there is provided a pill dispensing device that is positioned in the neck of the pill container to be operable by rotating the cap or cover of the container through a predetermined angle. When a pill is to be removed from the container, the container is inverted so that one of the pills falls into a hole provided to a rotatable member which is supported adjacent a fixed member. This rotatable member is turned by turning .the cap and after it is rotated through a predetermined angle the hole therethrough is aligned with a hole in the fixed member and the pill is transferred from the rotatable member to the hole in the fixed member. Further rotation of the container cap aligns the hole in another rotatable member with the hole in the fixed member whereby the pill is transferred from the fixed member to the hole in this rotatable member and from this latter hole the pill is dropped into the hollow member positioned in the neck of the container from which it may be removed by removing the cap completely from the container. Suitable means is provided for limiting the rotation angle of the rotatable members with respect to the fixed member and after a pill is dispensed through these members the cap of the container must be rotated in reverse direction in order to condition the device for the removal .of another pill from the container.

Further details and features of this invention will be set forth in the following specification, claims and drawing, in which:

FIG. 1 is a fragmentary view partially in section showing this pill dispensing device positioned in the neck of the pill container which is shown in inverted position;

FIG. 2 is an exploded view of the parts of this pill dispenser shown inverted between the neck of the container and the container cap;

FIG. 3 is a plan view of the innermost rotatable member of this device;

FIG. 4 is a plan view of the innermost rotatable member with the hole therethrough aligned with the hole in the fixed member which is positioned adjacent to one side of the rotatable member;

FIG. 5 is a plan view partially broken away showing the hole of another rotatable member which is positioned on the other side of the fixed member and which is aligned with the hole in the fixed member; and

FIG. 6 is a sectional view taken along the line 6-6 of FIG. 2 showing the rotation limiting groove in the one surface of the outer rotatable member.

Referring to the drawing in detail reference numeral 10 designates a container made of plastic, glass, or the like, and provided with a neck 11. A cup 12 is positioned in the neck and this cup is provided with ribs 13 which frictionally engage the inner walls of the neck and prevent rotation of the cup inside of the neck. The cup 12 is provided with a flange 14 that engages the lip of the mouth of the neck and limits the distance that the cup may be pressed into the neck. The cup 12 is also provided with a bottom 15 which is attached to the sidewall of the cup by suitable cement, glue, or the like, or it may be made integral with the sidewalls.

Another cup 16 is positioned inside of the cup 12 and is rotatable with respect to the latter. The cup 16 is provided with a bottom 17 which is integral with the sidewall or is attached to the sidewall by suitable cement, adhesive, or the like. The bottom 17 is positioned adjacent to the inner surface of the bottom 15 of cup 12. The exterior surface of the bottom 17 is provided with a groove 18 and the bottom 15 is provided with an annular projection 19 which fits into this groove. A hole 20 is provided extending through the bottom 17 and a similar hole 21 is provided extending through the bottom 15. The bottom 15 is also provided with an inclined groove 22 which gradually slopes from the outer surface of this bottom into the hole 21.

Centrally disposed holes 23 and 24 are provided to the bottoms 15 and 17, respectively, for receiving the rod 25 that is attached to the disc 26. The disc 26 and rod 25 are rotatable with respect to the bottom 15 through a portion of a turn as determined by the stop pin 28 that is attached to the bottom 15 and which extends into a groove 27 provided to the inner surface of the disc 26 as shown in FIG. 6. The inner end of the rod 25 is attached to the bottom 17 in the hole 24 by suitable cement adhesive, glue, or the like. The disc 26 is provided with a hole 29 extending therethrough and a groove 30 is formed in the outer surface of this disc gradually sloping from the surface thereof toward the hole 29.

This device is also provided with a cap 31 similar to the cap provided to the device shown in U.S. Pat. No. 3,424,355. This cap is provided with a cylindrical portion 32 that extends into the inner cap 16 and frictionally engages the ribs 16a provided on the inside of this cup. Thus, when the cap 31 is turned it turns the inner cup 16 and the bottom 17 of this cup and also the disc 26 within limits of the groove 27 and stop pin 28. The parts shown in the exploded view FIG. 2 are assembled in the neck of the bottle as shown in FIG..1 in which the bottle is shown in its inverted position so that the pills 33 are resting on thedisc 26. Thus, one of the pills will enter the hole 29 of the disc 26 when the bottle is inverted or a a pill will slide down the inclined groove 30 into the hole 29 as the disc 26 is turned by turning the cap 31.

Initially it is assumed that the holes 20, 21 and 29 are disposed with respect to each other as shown in FIG. 3. The holes 20 and 29 which are carried by the members 17 and 26, respectively, are rotatable together when the cap 31 is turned. However, the hole 21 which is carried by the member is stationary since the member 15 is attached to or is a part of the outer cup 12. The pin 28 is then positioned in the end 27a of the groove 27 adjacent to the hole 29. When the disc 26 is turned in the direction indicated by the arrow 34 by turning the cap 31 in this direction, while the bottle is in inverted position, the hole 29 passes over the hole 21 of member 15 and the pill 33 which was lodged in hole 29 drops into the hole 21 in member 15. Continuing the turning of the cap 31 in this same direction brings the hole of member 17 in line with hole 21 of member 15 and when these holes are aligned the pill 33 drops from hole 21 into hole 17 and out of the hole 20 into the inner cup 16.

At this time the pin 28 will be at the end 27b of the groove 27 thereby limiting rotation of the cap 31 in the direction indicated by arrow 34. The cap 31 may then be removed by pulling the cylindrical part 32 thereof out of the inner cup 16 and the pill dispensed by the device may be removed from the cap. No further pills may be dispensed from the bottle until the cap 31 and the cylindrical part 32 thereof are reassembled with the bottle by inserting the portion 32 into the inner cup 16 and rotating the cap in the reverse direction indicated by arrow 35 to bring the rotatable members 17 and 26 to the position with respect to the fixed member 15 shown in FIG. 3.

While we have shown and described a preferred embodiment of the invention, it will be apparent that the invention is capable of variation and modification from the form shown so that the scope thereof should be limited only by the scope of the claims appended hereto.
