DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(13) While various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.

(14) To facilitate the understanding of this invention, a number of terms are defined below. Terms defined herein have meanings as commonly understood by a person of ordinary skill in the areas relevant to the present invention. Terms such as a, an and the are not intended to refer to only a singular entity, but include the general class of which a specific example may be used for illustration. The terminology herein is used to describe specific embodiments of the invention, but their usage does not delimit the invention, except as outlined in the claims.

(15) The phrase and/or, as used herein should be understood to mean either or both of the elements being referred to, i.e., elements that are conjunctively present in some instances and disjunctively present in other instances. Other elements may optionally be present other than the elements specifically identified by the and/or clause, whether related or unrelated to those elements specifically identified unless clearly indicated to the contrary. Thus, as a non-limiting example, a reference to A and/or B, when used in conjunction with open-ended language such as comprising can refer, in one embodiment, to B without A (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

(16) It will be understood that the term preferably as used throughout the specification refers to one or more exemplary embodiments of the invention and therefore is not to be interpreted in any limiting sense. It will be further understood that terms of orientation and/or position as may be used throughout the specification, such as upper, lower, rear, side, forward, downward, upward, inner and so on, as well as their derivatives and equivalent terms, relate to relative rather than absolute orientations and/or positions.

(17) Referring to the drawings, and to FIG. 1 in particular, a pill counting apparatus 1 in accordance with an exemplary embodiment of the present invention is illustrated. The apparatus 1 may be interchangeably referred to herein as a pill tray or a pharmacy tray. As referred to herein, a pill is any suitable pharmaceutical dosage form. The pill counting apparatus preferably comprises a first trapezoidal portion 9, second trapezoidal portion 19, open-ended spout 40, common sidewall 50 and substantially transparent surface 70. Together the first trapezoidal portion 9, second trapezoidal portion 19, spout 40 and sidewall 50 define base portion 60 (FIG. 2).

(18) As illustrated in FIGS. 3 and 4, first trapezoidal portion 9 comprises a substantially planar first floor surface 10 having first 11, second 12, third 13 and fourth 14 sides. First side 11 and third side 13 are substantially parallel to each other, with first side 11 having a length that is less (i.e., shorter) than that of third side 13. The second trapezoidal portion 19 comprises a substantially planar second floor surface 20 having first 21, second 22, third 23 and fourth 24 sides. First side 21 and third side 23 are substantially parallel to each other, with first side 21 having a length that is less (i.e., shorter) than that of third side 23. Third side 23 of second trapezoidal portion 19 adjoins first side 11 of second trapezoidal portion 9. As shown in FIG. 5, second floor surface 20 form an obtuse angle 30 with respect to first floor surface 10. Common sidewall 50 extends upward from first floor surface 10, second floor surface 20 and third floor surface 43 (below), as shown in FIGS. 5 and 6.

(19) Without intending to limit the present invention to any specific dimensions, in one embodiment, the height of sidewall 50 as measured from first floor surface 10 is preferably at least 1.5 inches and more preferably at least 2.0 inches. The height of sidewall 50 as measured from third floor surface 43 is preferably within the range of 1.0 to 1.5 inches. The thickness of sidewall 50, first floor surface 10 and second floor surface 20 are all preferably within the within the range of 0.10 to 0.30 inches. The third side 13 of first trapezoidal surface portion 9 preferably has a length of at least 7.0 inches, more preferably at least 8.0 inches. The overall length of the pill counting apparatus (i.e., from third side 13 to spout 40) is at least 7.0 inches.

(20) As illustrated in FIGS. 6 and 7, open-ended spout 40 extends from second trapezoidal portion 19, and includes a third floor surface 43 that adjoins first side 21 of the second trapezoidal portion 19. As used herein, the term spout refers to any nozzle, funnel other opening through which the liquid or solids contents of a container may be passed or poured. Spout 40 is preferably shaped to fit within the opening of standard prescription vials such that the contents of apparatus 1 may be poured directly into a container such as a prescription vial. Without intending to limit the present invention to any specific dimensions, in one embodiment, open-ended spout 40 has a height of at least 1.0 inches.

(21) As illustrated in FIGS. 8-10, substantially transparent surface 70 covers second floor surface 20 and is immovable with respect to base portion 60. In another embodiment, substantially transparent surface 70 covers second floor surface 20 and a portion of first floor surface 10. In yet another embodiment, substantially transparent surface 70 covers a portion of third floor surface 43 (not shown). As illustrated in FIGS. 6 and 7, in one embodiment the substantially transparent surface 70 comprises a downwardly extending lip 72 that engages side wall 50. Substantially transparent surface 70 is preferably fixed to side wall 50 by a variety of attaching means known in the art including, but not limited to adhesives, glues, cements, welding, thermal bonding, injection molding and soldering. Alternatively, substantially transparent surface 70 is removably attached (i.e., for cleaning) to side walls 50 by a variety of attaching means such as clips, clamps, bolts and the like. Regardless of whether the substantially transparent surface 70 is fixed or removeably attached to the base portion 60, it is said to be immoveable with respect thereto because, when in use, the portion of the substantially transparent surface 70 is fixed relative to the base portion 60. The location of substantially transparent cover 70 relative to second floor surface 20 allows a user to visualize the entire base portion 60 such any pills lodged within pill counting apparatus 1 may be identified. Without intending to limit the present invention to any specific dimensions, in one embodiment, substantially transparent surface 70 is preferably characterized by a thickness within the range of 0.05 to 0.15 inches, a length of within the range of 6.5 to 7.5 inches and a width within the range of 2.5 to 3.5 inches.

(22) Firm plastics and flexible adhesives known in the art may be used to provide an apparatus capable of withstanding repetitive use as well as high impact forces, such as when inadvertently dropped to the floor. In one embodiment, first trapezoidal portion 9, second trapezoidal portion 19 and spout 40 are comprised of one or more polymers such as high density polyethylene (HDPE), low density polyethylene (LDPE) and polypropylene (PP). Similarly, transparent cover 70 is comprised of polymers such as high density polyethylene (HDPE), low density polyethylene (LDPE) and polypropylene (PP). Due to the wide variety pill colors and compositions (i.e., hard shelled capsule, soft shell capsules, gelatin capsules, capsules enclosing liquids, capsules enclosing powders etc.) the polymers used to form the first trapezoidal portion 9, second trapezoidal portion 19 and spout 40 preferably include a color that provides a high contrast (for example, light blue) with such pills while limiting the build-up of chalky binding agents.

(23) It will be understood that polymers such as the ones listed above are amenable to a variety of forming methods including, for example, vacuum forming and injection molding. These forming methods provide smoothly contoured transitions between the components of a pill tray, thereby avoiding edges, crevices, ledges, burrs etc. within which pills may become temporarily lodged. As best illustrated by FIG. 6 (shadowed lines), sidewall 50 extends upward from first floor surface 10 and second floor surface 20 with a smooth (e.g., rounded, tapered, gradual) contour that prevents pills from getting temporarily stuck. Spout 40 extends from second trapezoidal portion 19 with a similar smooth contour.

(24) Pill counting apparatus 1 may comprise a variety of sizes and shapes, and is in no way limited to the dimensions provided in the present figures. In a preferred embodiment, pill counting apparatus 1 with the approximate dimensions of 862 (lengthwidthheight) is able to hold the contents of a standard 60 dram prescription flat across first floor surface 10. The greater length of third side 13 of first floor 10 relative to first side 11 maximizes the area in which pills may be poured and counted. A user may count pills on first floor surface 10 while advancing them with a spatula towards spout 40. The dimensions of pill counting apparatus 1 defined by first trapezoidal portion 9 and second trapezoidal portion 19 permits the user to tip pill counting apparatus 1 such that the pills slide and/or roll towards spout 40. The height of sidewall 50 permits the entire contents of a prescription to be poured back into the original prescription vial without any spillage. Substantially transparent cover 70 allows the user to visually verify that no stray pills remain lodged within the pill counting apparatus. In the unlikely event that a stray pill is identified, the user may gently tap spout 40 against the outer rim of the prescription vial to dislodge the pill.

(25) All of the compositions and/or methods disclosed and claimed herein can be made and executed without undue experimentation in light of the present disclosure. While the compositions and methods of this invention have been described in terms of preferred embodiments, it will be apparent to those of skill in the art that variations can be applied to the compositions and/or methods and in the steps or in the sequence of steps of the method described herein without departing from the concept, spirit and scope of the invention. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit, scope and concept of the invention as defined by the appended claims.
