DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention is generally directed to pill fill trays and pill packaging systems and methods that provide proper alignment of a pill tray and a pill container (or pill card) when filling the pill container. One example embodiment is directed to a pill fill tray that includes an indexing member that extends from a surface of the pill fill tray that supports a pill card. The pill card includes a notch that aligns with and engages the indexing member thereby properly aligning the pill card relative to the pill fill tray.

Referring now to FIGS. 1-4, an example pill fill tray 10 is shown and described. Assembly 10 includes a base portion 12, first and second alignment walls 14, 16, a handle recess 18, and first, second and third indexing members 20, 22, 24. The base portion 12 includes first and second ends 26, 28, first and second sides 30, 32, top and bottom primary surfaces 34, 36, and a plurality of pill apertures 38 extending through the top primary surface 34. The first alignment wall 14 extends along the second side 32, and the second alignment wall 16 extends across the second end 28. The handle recess 18 is formed at the first end 26 and extends into the top primary surface 34.

The indexing members 20, 22, 24 are positioned along the second alignment wall 16. The members 20, 22, 24 include a height 40, a width 42, and a length 44 (see FIGS. 2 and 3). The height 40 is preferably great enough to provide engagement with a pill card having notches in an end of the pill card (see for example, the bubble card 60 shown in FIG. 13 and described in further detail below) engage the indexing members 20, 22, 24 when assembling the pill card with the pill fill tray 10. The height 20 may vary depending on such considerations as, for example, the thickness of the pill cards and the size or shape of the pill compartments (e.g., feature 72 in FIG. 13) of the pill card. The width and length 42, 44 may also vary depending on considerations such as features of the pill card. Also, there may be minimum and maximum dimensions of the indexing members 20, 22, 24 depending on the particular forming technique used for forming the assembly 10 such as, for example, molding, stamping, or other forming techniques.

Referring now to FIG. 13, an example pill card 60 is shown assembled with the pill filling assembly 10. The pill card 60 includes first and second ends 62, 64, first and second sides 66, 68, a plurality of apertures 70 (thirty-two total apertures), a plurality of pill housings or compartments 72, and first, second and third notches 74, 76, 78 formed along the second end 64. The layout of the apertures 70 substantially matches the layout of the apertures 38 of pill fill tray 10. The dimensions of notches 74, 76, 78 are also substantially equivalent to the width and length of the first, second, and third indexing members 20, 22, 24 of the fill tray 10. In some embodiments, the pill card 60 many include descriptive text related to the products held by the pill card 60 and other descriptive text related to, for example, the days of the week or time of the day in which the pills should be taken by a patient. The text may be oriented around the rows and columns of apertures 70. In some embodiments, it may be preferred to position the text between the first end 62 and the apertures 70.

The thirty-two aperture arrangement of pill apertures 38 may be well suited for a one-month pill schedule when using 1 pill aperture per day. The four columns of eight apertures shown in FIGS. 1 and 2 may also be well suited for an 8-day period of time in which a set of 4 pill apertures in each column corresponds to morning, midday, afternoon, and bedtime regime of pills.

Referring now to FIG. 14, an example notch 74 is shown in greater detail. Notch 74 includes an incoming radius R₁, a lower end radius, R₂, and a sidewall angle β. The specifications of the radiuses R₁, R₂, and sidewall angle β may provide certain advantages for both manufacturing of the notch as well as improving engagement between the notch 74 and a corresponding indexing member 20 on the pill tray 10. In one example, the angle β may be between about 0 and 30 degrees. The radius values R₁, R₂, may vary depending on, for example, the size of the corresponding indexing member to which it engages, material properties of the bubble card, the method of forming the notch (e.g., stamping versus molding), and other relevant considerations.

In one embodiment, the pill card 60 may include more notches than the number of indexing members on a corresponding pill fill tray. In still further embodiments, the bubble card may include several different notch sizes. Different notch sizes may be useful if corresponding indexing members also have varying sizes, or may be useful to improve the ease of alignment of the notches with the indexing members.

Referring now to FIGS. 5-8, another example pill fill tray 100 is shown. Tray 100 includes a base portion 112, first and second alignment walls 114, 116, a handle recess 118, and first, second, and third indexing members 120, 122, 124. The base portion 112 includes first and second ends 126, 128, first and second sides 130, 132, top and bottom primary surfaces 134, 136, and a plurality of pill apertures 138. Base portion 12 includes sixty-two pill apertures 138, which number of apertures may be well suited for any continuous 2-month period of time when using one of the pill apertures 138 per day.

Referring now to FIG. 9, another example pill fill tray 200 is shown and described. Pill fill tray 200 includes a base portion 212, first and second alignment walls 214, 216, a handle recess 218, and first, second and third indexing members 220, 222, 224. Base portion 212 includes first and second ends 226, 228, first and second sides 230, 232, top and bottom primary surfaces 234, 236, and a plurality of pill apertures 238. The arrangement of ninety pill apertures 238 may be well suited for a 3-month pill regime wherein each of the pill apertures corresponds to a single day.

Referring now to FIGS. 10-12, another example pill fill tray 300 is shown and described. Pill fill tray 300 includes a base portion 312, first and second alignment walls 314, 316, a handle recess 318, first, second and third indexing members 320, 322, 324 positioned along the second alignment wall 316, and fourth, fifth and sixth indexing members 350, 352, 354 positioned along the first alignment wall 314.

The base portion includes first and second ends 326, 328, first and second sides 330, 332, top and bottom primary surfaces 334, 336, and a plurality of pill apertures 338. The fourth, fifth and sixth indexing members 350, 352, 354 may be used in addition to or in place of the indexing members 320, 322, 324. Using two sets of indexing members may provide additional assurance of aligning the corresponding pill container (or pill card) along the top surface 334. Using two sets of indexing members may require that the card notches be fit down vertically over the top of the indexing members rather than sliding in horizontally in a plane of the surface 334 as may be possible with fill trays 10, 100, 200 described above.

The embodiments shown in FIGS. 1-13 include indexing members provided in sets of three. Other embodiments may include only a single indexing member along one of the alignment walls. In still other embodiments, the indexing member may be positioned along one of the first end or the first side end and configured so as to extend vertically above the top primary surface for engagement with a card resting on top of the top primary surface of the pill fill tray. In yet further embodiments, the card may include flanges or other bent structure that wrap around from a top surface to a side surface of the pill fill tray along at least one of the sides or ends of the pill fill tray. These flanges or bent edges may include notches formed therein that engage an indexing member positioned along the first end or first side. This type of configuration may eliminate the need to position the indexing member in a position protruding vertically above the top primary surface of the fill tray.

Various other configurations and embodiments may fall within the spirit and scope of the present invention. Such alternative embodiments may include some type of protrusion or recess that engages a respective notch or protrusion of the pill container or pill card that is to be filled to align features of the container/card with features of the fill tray. Alignment of the pill compartment of the container/card with apertures of the pill fill tray may be particularly important. In one embodiment in which the pill fill tray includes more apertures than the number of pill compartments of the container/card, proper alignment using the indexing features described herein may be especially useful.

The present invention should not be considered limited to the particular examples or materials described above, but rather should be understood to cover all aspects of the invention as fairly set out in the attached claims. Various modifications, equivalent processes, as well as numerous structures to which the present invention may be applicable will be readily apparent to those of skill in the art to which the present invention is directed upon review of the instant specification.
