Description

BACKGROUND OF THE INVENTION

[0001] This invention relates to a pill dispenser that aids in the dispensing of pills from a medicine bottle or container typically used for over the counter or prescription medicines in pill form. The task of shaking one or two pills from an irregularly shaped bottle or cylindrical container can often be challenging. Frequently, more pills than are desired spill into the hand and the excess have to be returned to the bottle. In addition to the potential for contamination of the replaced pills, the task is annoying and may be frustrating to seniors with impaired functionality of their hands. The spiral pill dispenser of this invention is an inexpensive solution that controls the movement of pills in a pill bottle that is either irregularly shaped or is cylindrical in form as is frequently used for prescription medications in pill form.

[0002] The spiral pill dispenser of this invention is designed for use with an existing pill bottle or for incorporation into the inner surface of a pill bottle during the manufacturing process. These and other features of the spiral pill dispenser are described in relation to the preferred embodiments set forth in the detailed description of the preferred embodiments.

SUMMARY OF THE INVENTION

[0003] The invented spiral pill dispenser is designed and constructed to aid in the discharge of pills from a pill bottle. The term, "pill" includes both conventional compressed powder formulations and capsules, including liquid-filled capsules. Similarly, the term "bottle" includes both irregularly shaped bottles such as plastic or glass aspirin bottles, and cylindrically shaped bottles such as the plastic canisters that are typically used for pharmaceutical drugs in pill or capsule form. The spiral pill dispenser is in the form of a raised coil on the inside wall of the bottle. The raised coil is provided on at least the portion of the inside of the container next to the opening. The raised coil spirals from a start point within the bottle to a termination next to the bottle opening.

[0004] One are more pills are retrieved by a simple sequence. After removing the bottle cap on a bottle containing pills and tipping the bottle in a customary fashion, the bottle is then gently rotated to guide contained pills along the spiral to the opening for discharge. A gentle shake can accompany the rotation to control the sequential discharge, so that only one or two pills are dispensed under the user's control. This simple mechanical addition to the ordinary pill bottle, along with the intuitive rotation of the bottle, facilitates the expedient discharge of pills, one by one.

[0005] The dimensions of the raised coil or ridge on the inside wall of the pill bottle naturally depend on the size and configuration of the pills. Smaller pills will require a reduced size in the height of the coils and the spacing of one coil from another in the spiral. It is to be understood that while the preferred embodiment would incorporate the raised coils directly into the wall of the container during manufacturing, other embodiments allow addition of the spiral coil to existing bottles. For example, a preformed coil having an adhesive contact surface can be installed on the inner wall of the bottle. Alternately, for cylindrical canister-type bottles, a tubular sleeve with a raised helical coil on its inner wall can be inserted into the entire length of the bottle, or for both cylindrical and irregular-type bottles, into just the neck of the bottle. These and other features are disclosed in the detailed description that follows a brief description of the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Referring to FIGS. 1 and 3, the pill dispenser, designated in general by the reference numeral 10, is shown in two different embodiments. In FIG. 1 the pill dispenser 10 is integral with a pill bottle 12. In FIG. 3 the pill dispenser 10 is an added accessory element to a pill bottle 11 of the type typically used for pharmaceutical drugs.

[0010] In the unitary embodiment of FIG. 1, the irregularly shaped bottle is typical of the type found in retail stores for over the counter medicines. In this embodiment, the pill dispenser 10 is in the form of a raised spiral coil 14 that is located at the neck 16 of the pill bottle 12 and comprises approximately three turns of the spiral coil 14 formed during the manufacturing process of the bottle. In molding plastic pill bottles, the incorporation of a pill dispenser 10 that is integral with the bottle adds a convenience for the user that is a small additional expense.

[0011] The pill bottle 12 of FIG. 1 is shown in cross-section to illustrate the raised spiral coil 14 that spirals to the bottle opening where it terminates. The raised spiral coil 14 is shown enlarged in the partial cross-sectional segment of FIG. 2. In FIG. 2, the configuration of the coil 14 is parabolic to provide rounded internal edges to minimize any chaffing to the pills 18 during dispensing and to guide pills into the trough 20 between the raised coils 14. Preferably, there should be at least three turns of the spiral coil and the size of the raised coils 14 and width of the trough 20 should correspond generally to the size of the pills 18 contained by the bottle 12. The width of the trough 20 should be slightly greater than the width of a pill 18 and preferably slightly less than its length to insure a sequential disposition during dispensing.

[0012] It is to be understood that the term "pills" includes capsules. Capsules are frequently elongated and therefore require a greater width to the trough 20 than a circular or elliptical pill in order to round the helical path in the neck 16 of the bottle 12 during dispensing. The preferred number of turns can be reduced to accommodate pills of larger size.

[0013] The pill bottle 12 of FIG. 1 has a top 22 with a lip 24 that engages a press-on cap 26 in a conventional manner. It is also to be understood that an irregularly shaped bottle 12 is differentiated from the cylindrical pharmaceutical pill bottle 28 of FIG. 3 only for purposes of showing how the invented spiral coil pill dispenser can be adapted to a variety of conventional pill bottles. The shape of the bottle 12 shown in FIG. 1 is merely an example of one irregularly shaped bottle. If the dispenser 10 is integral and fabricated during the manufacture of the bottle, the bottle may have a longer neck than the typical bottle to add additional turns of the coil. Alternately, the bottle with the integral spiral coil dispenser 10 may be cylindrical in shape and of the type shown in FIG. 3.

[0014] Referring now to FIG. 3, the pill dispenser 10 is in the form of a cylindrical (or slightly truncated conical) sleeve 40. The sleeve 40 has a shell 42 with a top 44 having a thin rim 46 which seats on the top 48 of the cylindrical bottle 28. For convenience the sleeve 40 and the bottle 28 are transparent to illustrate the internal raised spiral coil 49 in dotted line on the inside wall 50 of the sleeve. The exploded view of FIG. 4 illustrates the manner the sleeve 40 is inserted into the conventional pharmaceutical pill bottle 28. The pill bottle 28 has a cap 52 that seats over the thin rim 46 of the sleeve 40 and engages a flange 54 at the top 48 of the cylindrical bottle.

[0015] It is to be understood that just as the integral or unitary raised spiral coil can be incorporated into the wall of a cylindrical bottle during manufacture, a sleeve with an internal raised spiral coil can be adapted for insertion into the neck of an irregularly shaped bottle. Additionally, other modifications can be made without departing from the spirit and scope of the invention. For example, the dispenser can be in the form of a coil that is adhesively attached to the wall of the bottle in a short spiral.

[0016] During use, the method of dispensing pills from a pill bottle having a raised spiral coil in the neck of the bottle located next to the top opening is intuitive. The pill bottle is gently tipped to urge contained pills seated in the trough between raised turns of the coil toward the opening. The pill bottle may optionally be gently shaken to advance the pills to the neck and opening of the bottle. The pill bottle in the tilted position is gently rotated with a clockwise motion to dispense individual pills. Although the procedure is designed for the ease of a right-handed person, a left-handed person can easily adapt with a counter-clockwise rotation. Alternately, a raised spiral coil can be constructed with an opposite rotation for a left-handed person, particularly for the inexpensive insert embodiment.

[0017] These and other features have been described with respect to multiple preferred embodiments to illustrate the scope of the invention which is set forth in the claims that follow.
