Description

AUTOMATIC PILL DISPENSER

This application claims the benefit ofU.S. Patent Application No.09/293,090, filed April 15, 1999.

BACKGROUND OF TEE INVENTION

This invention relates generally to a method and device for dispensing pills or vitamins. More particularly, this invention relates to a novel device for automatically dispensing pills or vitamins that absolves the need for removing caps from bottles.

Many people, particularly the elderly, consume pills, vitamins, natural herbs, and/or other dietary supplements on a daily basis. The consumption of such pills ordinarily requires removing the screw cap from a small bottle. This can become quite cumbersome when performed on a daily basis, and, for individuals with arthritis or other ailments impairing the dexterity of their hands, it can develop into a challenging, if not impossible, task. Further exasperating efforts of the pill t,aker are the standard child safety caps, a required feature of most medicines, which are designed to prevent children from opening the bottles and accidentally consuming the medicine. Such caps often require the application of extra force, or the manipulation of small plastic parts, which can be extremely difficult for a person suffering from arthritis or similar afflictions.

Thus, there is a need for a system of automatically dispensing pills and vitamins that will avoid the problems associated with opening and closing several small bottles on a daily basis. Such a system should simply and reliably dispense pills. The present invention is designed to address this need. SUMMARY OF INVENTION

The present invention is a pill dispensing device designed to obviate the need for repetitive opening and closing pill containers. The device consists of a housing, a dispensing chamber, and means for rotating the chamber such that pills or vitamins are easily dispensed to the user.

One of the advantages of the invention is to provide a rotating chamber with a plurality of slots to contain pills to be dispensed to a user.

Another advantage of the invention is to provide a pill dispensing device that can be manually or automatically advanced such that the user's pills are dispensed.

Another advantage of the invention is to provide a pill dispensing device that contains a removable rotating chamber that can be filled with the desired pills directly by a pharmacist or a pill manufacturer.

Another advantage of the invention is to provide a pill dispensing device that contains a plurality of rotating cylinders such that a variety of pills can be dispensed.

Another advantage of the invention is to provide a pill dispensing device that contains a safety feature such that the pills are not dispensed without the use of a special key or computer code.

DETAILED DESCRD7TTON OF THE INVENTION

The present invention preferably relates to a device for automatically dispensing pills, vitamins, natural herbs, etc. As used in the specification and the appended claims, the term "pill" shall mean any ingestible pill-like item, whether it be medicine, vitamins, or herbs and the like. Referring to Fig. 1, the device 10 consists of a housing 11 that holds the dispensing chamber 12. The dispensing chamber 12 is a rotating chamber with a multitude of pill containment slots 14 in which the pills are placed. The pill containment slots 14 may be any size or shape, so long as there is at least one opening through which pills will be dispensed. Multiple openings may also be used. The slots 14 may be designed to hold a single pill, or a multitude of pills, and may be any size to fit the intended purpose. The chamber 12 can have any number of slots 14, but it is preferable to use a number of slots 14 that will match the calendar in some way so that the chamber 12 is refilled by the user on a regularly scheduled basis. For example, the chamber 12 may have slots 14 in multiples of seven (7) so that the chamber 12 is refilled on a weekly or bi-weekly basis.

Alternatively, the chamber 12 may have thirty (30) slots so that the dispenser is filled monthly. Those of skill in the art will readily recognize that any number of slots 14 may be useful in the present invention.

The housing 11 includes a pill dispenser or hole 15 at the bottom (see Fig. 2) through which the pills are dispensed. The chamber 12 is designed to rotate so that one slot 14 will align with the dispensing hole 15 and the pill will fall from the slot 14 and through the hole 15. Any commonly known means for rotating the chamber may be used. The means for rotating the chamber may be a completely mechanical system requiring a user to manually rotate the chamber or an automated system requiring minimal or no user input. One such means contemplated for the present invention is a battery operated motor 25. The motor may be activated by a standard electric switch 16 located on the housing 11. In Fig. 1, the switch 16 is in the form of a small button. The user may depress the button, causing the chamber 12 to rotate, until the next slot 14 is aligned with the hole 15 and a pill is dispensed. The device 10 may also use standard electricity from a household outlet to operate the motor. In the alternative, those of skill in the art will recognize that the chamber may remain stationary and the housing designed to rotate. Such a system is considered within the spirit and scope of this invention. The device preferably includes a lid or cover to protect the chamber from dust or other contaminants.

As will be readily apparent to those of skill in the art, there is no limit to the shape or configuration of the chamber in the present invention. Any chamber capable of rotating in such a manner that pills will fall through the dispensing hole is considered within the spirit and scope of this invention. The rotation of the chamber may be accomplished through any known means, and those of skill in the art will recognize a variety of known means that may be employed. However, known means are complex and expensive. Referring now to Figure 4, a simple and inexpensive way to accomplish the chamber rotation is through the use of a chamber 12 having gear teeth 35 whereby a corkscrew mechanism 30 engages the gear teeth 35 on the chamber 12. When the user activates the electric switch 16, the corkscrew mechanism 30 rotates, advancing the chamber. Alternatively, the rotation may be accomplished by attaching the motor 25 directly to the rotating chamber 12.

Another possible embodiment of the present invention involves multiple chambers within a single housing so that a variety of pills may be dispensed from a single unit. Such an embodiment is shown in Fig. 5. In Fig. 5, three chambers 12 are aligned for vertical rotation, rather than the horizontal configuration illustrated previously. In this configuration, the slots 14 may have holes in the side, or on one end, and such holes will align with dispensing holes 15 at the bottom of the housing

11 as discussed above. The multiple chambers could also have a horizontal configuration, but this would require an extremely large housing. Referring now to Fig. 7, a possible housing 11 for the pill dispenser is shown. The housing 11 includes a lid 17 that may be opened for access to the dispensing chamber 12 (shown as hidden in Fig. 7), and means for rotating the chamber. The lid 17 may include a loading chute 19 for loading pills into the chamber 12. The loading chute 19 may be any hole through which pills may be placed in the containment slots

14, and the hole preferably has a funnel-like shape for easy loading. To use the loading chute 19, the dispensing hole 15 needs to be covered. The chamber 12 is then rotated slot-by-slot so that pills may be loaded into each individual slot 14. The dispensing hole 15 may then be opened for later use. The loading chute 19 preferably includes a lid or some other means for closing the chute after the pills have been loaded.

It is contemplated that the pharmacist or user may load the pills into slots 14. Rather than supplying pill bottles, the pharmacist could instead place the pills in the device 10. When the user has consumed all of the pills in the device 10, he may return the device 10 to the pharmacist for a refill. Alternatively, the user may simply load the pills into the device 10 after purchase. This would reduce the number of times the user has to handle the cumbersome bottles, and provide a convenient method for maintaining and distributing the pills. In a preferred embodiment of the present invention, the chamber 12 may be removed from the device 10 to be refilled. The user may then take the chamber 12 to the pharmacist for filling, or purchase a new, pre-filled chamber 12 for placement inside the device 10. In this way, pill manufacturers may stock the shelves with pre-filled chambers for sale to the users. As shown in Fig. 6, this removable chamber 12 may also include the days of the week or calendar dates on the side of the chamber 12 which will be displayed when the chamber 12 rotates. This will assist the user in keeping track of dosages consumed.

Alternatively, the device 10 may simply be opened and the chamber 12 filled with pills while remaining with the housing 11. Also shown in Figure 6 is that the pill dispensing device 10 can be mounted under a kitchen cabinet 51, for example, using suspending brackets 52 connected to the underside of kitchen cabinet 51 and fashioned to removably accept an interlocking portion 53 fixed to dispensing device 10. One can then slidably and removably attach dispensing device 10 to brackets 52. Dispensing device 10 is thereby conveniently suspended from kitchen cabinet 51.

Preferably, the motor and switch providing rotation to the chamber are designed so that the chamber's rotation is controlled as opposed to a freely rotating chamber. For instance, the chamber 12 will preferably rotate only enough to allow the next slot 14 to align perfectly with the dispensing hole 15. The chamber 12 should then stop rotating and not move until the switch 16 is activated again. One simple and inexpensive way to accomplish this controlled rotation is through the use of a gear system, having a spring loaded stopper 40 (snap switch) with a stopper arm 41 as shown in Figs. 1 and 4. When the switch 16 is activated, the stopper 40 releases and the motor 25 turns the chamber freely. The chamber may have notches

20 such that rotation of the chamber stops when spring loaded stopper arm 41 engages a notch. When the stopper arm 41 engages the notch, it forms a connection with the stopper 40 which interrupts electric current to motor 25. This process is repeated each time switch 16 is activated. This controlled rotation means is included by way of example only and is not intended to limit the scope of the present invention.

Another preferred feature of the present invention is a system to prevent unwanted users from having access to the pills. This may also be considered a child safety feature. As described so far, any user could activate switch 16 and obtain a pill. This would be an undesirable feature if small children were in the home. To prevent unwanted access to the pills, a key system 54 as illustrated in Fig. 6 may be devised that would limit users. The switch 16 may easily be configured so that it does not activate the motor unless a key 54 or other type of triggering device is inserted into the device 10. This would avoid accidental or unwanted pill dispensing. The key device 54 is discussed as an example only, and it should be recognized that any type of security system that avoids unwanted pill dispensing may be utilized.

Referring now to Fig. 8, another embodiment of the present invention utilizes a computerized control pad 50 to control distribution of the pills. The computer may be programmed with date and time so that pills are dispensed only when needed. Once the user has obtained a pill, the chamber 12 will not rotate again until the designated time for another dosage. In addition, the computerized system may utilize a numeric combination keypad as the security device. Further, the computerized system may also include an alarm or other device so that the user may be notified when it is time to take particular medication or pills. The device may also automatically dispense the pills to a tray or holding device to be taken by the user at their convenience. It should be appreciated that the present disclosure does not include details regarding the computerized control pad. The design of such a computer interface is well within the ordinary skill in the art, and would be designed similar to the control interface of microwave ovens or NCRs.

In some cases it may be preferred to use a manual mechanism to rotate chamber 12 a fixed distance. Figs. 9a and b, and 10a, b, c, and d, show a simple and inexpensive means to produce manual rotation. As seen in Fig. 9a, chamber 12 has a series of angled teeth projections 60 attached to the top of chamber 12 and projecting vertically. Plunger or handle 61 has a spring 62 on the portion of plunger

61 external to housing 11. The internal portion of plunger 61 engages tooth projection 60. Figures 10a, b, c, and d, illustrate how plunger 61 rotates chamber 12. When a user pushes the external portion of plunger 61 inward, plunger 61 pushes against the flat portion of tooth projection 60 and rotates chamber 12 while spring

62 is compressed. When the user releases plunger 61, spring 62 pushes plunger 61 outward. As plunger 61 moves outward, the internal portion of plunger 61 moves up the angled portion of an adjacent tooth projection 60 and falls behind the flat portion of an adjacent tooth projection 60. The chamber 12 is now ready for a second rotation to the next pill containment slot 14. The tooth projections may also be placed at other sites on the chamber and the plunger may also function in other positions or as a lever. Because of the simplicity of the present invention, no mechanism is required to prevent reverse rotation of chamber 12. As chamber 12 rests on the bottom of housing 11 there is sufficient friction to prevent reverse rotation.

In some cases, it may be desirable to have a stopper mechanism to prevent reverse rotation of chamber 12. Figures 9a and b, and 11 illustrate a stopper tab. The inside portion of housing 11 contains a flexible stopper tab 63 which engages notch 20 on the side of chamber 12 during forward rotation. A slight force with the plunger or handle 62 as the notch engages stopper tab 63 will bend stopper tab 63. As the stopper tab 63 bends, the notch 20 passes the stopper tab 63, and the notch will prevent reverse rotation as it encounters tab 63, if chamber 12 tends to rotate in reverse. A similar ball and socket tab could also be used as shown in Figure 9b. Notches 20 on chamber 12 could be arranged to form a pocket or socket 70 to accommodate the ball-like head 71 of tab 63. Head 71 is biased towards socket 70 by spring 72.

Figure 11 shows a variation of the device shown in Figure 9. The teeth projections 60 project horizontally instead of vertically, and handle or plunger 61 has spring 62 on the inside of housing 11. In this case spring 62 is stretched as plunger 61 pushes against tooth projection 60. Figure 11 also shows how the device of the present invention can be constructed with multiple chambers for high volume use or for different time periods such as morning, noon, and night. The chambers may be arranged horizontally or vertically. Figure 12 shows another embodiment of the present invention where the handle or lever 61 for rotating chamber 12 pivots on the axle 64 of chamber 12 and extends outward from the side of housing 11. This lever 61 requires no spring for retraction as seen in Figures 9, 10, and 11, since it can be conveniently manually moved back and forth. However, the lever can incorporate a spring at the pivot point on axle 64 to bias lever 61 to the right or left as desired.

Figure 13 shows the preferred embodiment of the present manually operated invention, which does not require teeth projections 60 on chamber 12. This embodiment has a lever 61 similar to that shown in Figure 12 except that it has a hinged flexible tab 66 which will rotate forward, or to the right, for example, as the lever is moved to the left and the tab 66 encounters partition 65 of slot 14. Because tab 66 is hinged to rotate only to the right, for example, it can be moved over partition 65 by lever 61 as tab 66 rotates upward. Once tab 66 is over partition 65, the lever can be moved to the right and tab 66 will engage partition 65. Since tab 66 is hinged to rotate only to the right but not to the left, it will put force on partition 65 as the lever 61 is moved to the right and the chamber 12 will then rotate forward or to the right. The hinged tab may be constructed to provide either right or left rotation as the user needs. The lever may incorporate a spring at the pivot point on axle 64 to bias lever 61 to the right or left as desired. The lever 61 extends outside housing 11 through an opening. The width of the opening controls the extent of rotation. The opening may be variable in width. Instead of partitions circular slots with projections may be used to engage tab 66.

Figure 14 shows a further embodiment of the present invention where chambers 12 act as wheels connected in series by belt 67, as is seen customarily with a fan belt or pulley belt arrangement. A front view of this arrangement is seen in

Figure 15 along line a-a. Separate slots 14, or containers, are attached to belt 67.

A chamber 12 adjacent to housing 11 can contain teeth projections 60, and a handle, plunger, or lever 61 as shown in Figures 9 - 13 to rotate the chamber 12. The frictional nature of belt 67 as it engages chambers 12 will provide enough friction to prevent reverse rotation of the chambers 12. This embodiment allows for numerous slots in a relatively small space. The assembly of wheels, belt, and slots can be replaced with another assembly. The device may also contain multiple assemblies.

The assembly may be arranged in horizontal or vertical positions.

Because of the simplicity of the present invention, it can be miniaturized using either the motor version or handle versions so that the device can be portable and carried conveniently. Such a miniaturized version would preferably be 6 to 8 inches long, 3 to 4 inches wide, and VA to 1 " thick. Other ranges of sizes, however, are within the scope of the present invention.

The devices shown in Figs. 9 - 15 have additional features. They have (1) a housing having at least one opening through which pills are dispensed, when the chamber is rotated; (2) notations on the chamber or belt corresponding to a calendar, such markings being visible to the user, to assist the user in determining which day to dispense pills; (3) removable, replaceable chambers or assemblies; (4) a loading chute that may be used to load pills into slots; (5) a programmable computer control for rotating the chamber; and (6) the chambers or assemblies may be arranged horizontally or vertically.

While various modifications and changes of the device described herein will be apparent to one having ordinary skill in the art, such changes are included in the spirit and scope of this invention, and the invention should not be limited by the specific embodiments described herein.
