The closure is moved vertically by a rotating cam band having means indicative of the last previous time or event when the dispenser was opened.
BACKGROUND OF THE INVENTION Field of the invention This invention relates generally to dispensing containers and more particularly to recording dispensing containers in which a successive indication is given each time the container is opend for dispensing a pill.
Description of the prior art Devices are known in the prior art which permit opening of pill dispensers only upon the happening of a predetermined event and other devices which record the opening of the pill dispenser. Such devices are described in U.S. Patents 3,151,599 issued to Livingston on Oct. 6, 1964; 3,206,064 issued to Cantu et al. on Sept. 14, 1965; 3,261,455 issued to Gayle et al. on July 19, 1966; and 3,278,010 issued to Katz on Oct. 11, 1966. The present invention is an improvement in dispensers of this type and more specifically is an improvement over my Patent 3,355,067 issued Nov. 28, 1967.
SUMMARY This invention relates to a pill dispenser which has a cylindrical container having a dispensing opening at the top thereof which is closed by a vertically reciprocating closure and which is moved into open position by a rotatable cam band. Means are provided on the band for recording the last time that pills were dispensed from the container.
The primary object of the invention is to provide a pill dispenser which will record the time of the dispensing of the pills.
Another object of the invention is to provide a pill dispensing container of the type described above `which is inexpensive to manufacture, simple to assemble and use, and which is provided with a latch for preventing access to the pills by a child.
Other objects and advantages will become apparent in the following specification when considered in light of the attached drawings.

3,477,561 Patented Nov. 1l, 1969 "Ice DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail, wherein like reference characters indicate like parts throughout the several figures, the reference numeral 10 indicates generally a dispensing container constructed in `accordance with the invention.
The dispensing container 10 includes a general cylindrical hollow body 11 having a top wall 12 extending thereacross. A cylindrical guide sleeve 13 is integrally formed with the top wall 12 and depends therefrom in coaxial relation to the body 11. A generally circular cap 14 is pressed onto the lower end of the body 11 as can be clearly seen in FIGURES 2 and 3.
An outwardly extending annular shoulder 15 is formed on the outer face of the body 11 adjacent to but spaced from the bottom edge thereof.
A cylinder 16 is mounted on the cylindrical body 11 and is arranged for axial sliding movement thereon as well as a slight rotational movement with respect thereto. The cylinder 16 has an integral circular top wall 17 with an upstanding ring 18 integrally formed thereon `and axially arranged with respect to the cylinder 16. A cap 19 is pressed onto the ring 18 as can be best seen in FIGURES 2 and 3.
A combination pointer and cam tooth 20 is integrally formed on the lower edge of the cylinder 16 in depending relation thereto and is provided with an indicator point 21 at the lower end thereof.
A dispensing aperture 22 is formed in the sidewall of the cylinder 16 adjacent the top wall 12 and has an arcuate pouring spout 23 arranged in underlying relation thereto and integrally connected to the cylinder 16. The top wall 12 of the cylindrical body 11 has a dispensing aperture 24 formed therein for reasons to be assigned.
A cam ring 25 is positioned about the cylindrical body 11 in engagement with the shoulder 15 and is arranged for rotation on the cylindrical body 11. The cam ring 25 has a diameter equal to the diameter of the cylinder 16 and is arranged to engage the point 21 of the tooth 20. A plurality of cam surfaces 26 are formed on the upper edge of the cam ring 25 terminating at their upper edges in notches 27 as can be clearly seen in FIGURE 1.
A retainer shaft 28 extends through the guide sleeve 13 for vertical reciprocating motion therein and has its upper end provided with dat sides at 28 extending through an opening of the same shape in the center of the top wall 17 terminating within the ring 18 under the cap 19. The flat sides 28 and the same shaped opening in the top wall 17 prevent relative rotation of the top wall 17 and the shaft 28. The upper end of the retainer shaft 28 has an annular groove 29 formed therein to receive a bifurcated retainer washer 30 preventing the cylinder 16 from being detached from the retainer shaft 28. A relatively thick disc 31 is integrally formed on the lower end of the retainer shaft 28 and has a diameter slightly smaller than the inner diameter of the cylindrical body 11. A guide bar 32 is integrally formed on the inner surface of the cylindrical body 11 and extends upwardly from the bottom thereof at a slight angle to the vertical. A notch 33, formed in the peripheral edge of the disc 31, engages over the guide bar 32 so that the disc 31 is prevented from free rotation by the guide bar 32. A stop S is integrally formed on the upper end of the guide bar 32 in a position to engage and limit upward movement of the disc 31. A double bevel B is formed on one edge of the disc 31 for reasons to be assigned.
A U-shaped cut 34 in the side wall of the cylindrical body 11 adjacent to but spaced from the bottom thereof delineates a latch-tongue 35 which is integral with the cylindrical body 11 but is resiliently disposed with respect thereto. The latch tongue 35 has an inwardly projecting ange 36 with a triangular keeper member 37 formed ti ereon. An arm 38 depends from the disc 31 and has a triangular keeper member 39 integrally formed thereon for cooperative engagement with the keeper member 37 as can be seen in FIGURE 2.
A handle H is formed on the arm 38 to grip when removing the disc 31 from the cylindrical body 11. Inward press-ure on the latch tongue 35 moves the keeper member 37 inwardly out of alignment with the keeper member 39 so that the disc 31, as well as the cylinder 16, may move upwardly with respect to the cylindrical body 11. In assembling and disassembling the pill dispenser the cap 19 retainer washer 30 and cap 14 are removed and the disc 31 is pulled downwardly in the body 11. The double bevel B cams the keeper 38 out of the path of the disc 31 when moving in either direction.
Upon pressing the tongue 35 inwardly with one hand and simultaneously rotating the cam ring with the other hand the cylinder 16 is forced upwardly on the cylindrical body 11 moving the upper wall 17 out of the position shown in FIGURE 2, where it closes the aperture 24, into the position shown in FIGURE 3, where the aperture 24 is opened and generally aligned with the aperture 2. In this position the point 21 of the tooth 20 is engaged in the notch 27 and the pill dispenser 10 is tilted to feed pills through the apertures 24, 22 into the hand of the user. After suflicient pills for the required dose have been dispensed from the pill dispenser l0, the cam ring is turned an additional amount to disengage the point 21 of the tooth 20 from the notch 27 permitting it to drop to the position shown in FIGURE 1 thus closing the aperture 24 and the aperture 22 simultaneously engaging the keeper member 32 with the keeper member 37 latching the cylinder 16 to the cylindrical ybody 11 to prevent sliding motion therebetween.
As the disc 31 drops to close the pill dispenser the triangular keeper 39 cams the keeper 39 inwardly to permit the keepers 37, 39 to pass each other and then latch together as shown in FIGURE 2. the disc 31 is relatively thick to provide suicient weight to cause it to drop to closed position as the cam ring 25 is turned to closed position.
While not essential to the invention, it is preferable that the dispenser be constructed of a transparent plastic material such as the polyacrylic resins, the polystyrene resins, or an equivalent resinous material.
The construction of the instant invention requiring both the rotation of the cam ring while simultaneously holding the latch tongue depressed requires a dexterity and an understanding of the mechanism generally beyond the capability of young children but which can be easily operated by older children and adults when needed.
Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the invention.
