DETAILED DESCRIPTION OF THE INVENTION

[0057] FIGS. 1-6 show a medicine dispensing device 1 according to a first exemplary embodiment of the invention. The medicine dispensing device 1 is used to dispense sorted drugs, medicaments or medicine items (not shown), such as tablets or pills, or other dosed portions of medicine in a drop direction D into a collection unit of a medicine packaging machine as disclosed in WO 2014/081286 A1.

[0058] As best seen in FIG. 2, the medicine dispensing device 1 comprises a tray 2 and a drop plate 3 below the tray 2 in the drop direction D. The tray 2 is provided with a tray body 20 and a plurality of storage cavities 21 formed in said tray body 20 for receiving one or more of the medicine items. As shown in FIG. 1, the storage cavities 21 are arranged in an matrix of rows and columns. Alternative configurations of the storage cavities 21 also fall within the scope of this invention.

[0059] As best seen in FIG. 1, the drop plate 3 is provided with a plate body 30 and a plurality of drop openings 31 formed in said plate body 30. The drop openings 31 are dimensioned to allow for passage of the medicine items through the drop plate 3 in the drop direction D. The drop plate 3 is slidable relative to the tray 2 in a sliding direction S perpendicular to the drop direction D between a hold position, as shown in FIGS. 1-5, and a drop position. When sliding from the hold position into the drop position and vice versa, the drop plate 3 is moved relative to the tray 2 in or along a dispensing stroke or path X extending from a first endpoint E1 defined by one of the hold position and the drop position up to a second endpoint E2 defined by the other one of the drop position and the hold position. In this exemplary embodiment, the first endpoint E1 corresponds to the hold position and the second endpoint E2 corresponds to the drop position.

[0060] In the hold position, the plurality of drop openings 31 are out of line with the plurality of storage cavities 21 in the drop direction D. In other words, in the hold position, the plate body 30 effectively closes the cavities 21 in the drop direction D. In the drop position, the plurality of drop openings 31 are aligned with the plurality of storage cavities 21 in the drop direction D to drop or dispense the medicine items from the cavities 21 in said drop direction D.

[0061] In this exemplary embodiment, the number of drop openings 31 is equal to the number of cavities 21 in the tray 2. Hence, each drop opening 31 is associated with or dedicated for opening and closing a respective one of the cavities 21. More in particular, the drop openings 31 are arranged in a similar array of rows and columns, such that they are all equally offset and aligned in the hold position and the drop position, respectively. Alternatively, two or more cavities 21 may have a common drop opening, i.e. in the form of a drop slot—not shown but known per se—that can be aligned with several cavities 21 at once.

[0062] As best seen in FIG. 3, the drop plate 3 is provided with a pull member 32 to manually pull the drop plate 3 in the sliding direction S from the hold position at the first endpoint E1 into the drop position at the second end point E2. As shown in FIGS. 1 and 3, the tray body 20 is provided with a corresponding pull recess 22 at the location of said pull member 32 to allow manual access to said pull member 32. Note that the pull member 32 is spaced apart from the tray body 20 in the hold position at the first endpoint E1 over a clearance W, as shown in FIG. 3, that allows for further sliding movement of the drop plate 3 beyond the first endpoint E1, as will be explained in more detail hereafter.

[0063] The drop direction D is preferably vertical or substantially vertical, so that the medicine items may drop from the cavities 21 under the influence of gravity.

[0064] In the exemplary embodiment as shown in FIG. 2, the cavities 21 are open at the side of the tray body 20 that faces away from the drop plate 3, i.e. the upper side of the tray body 20, to receive the medicine items from above. In an alternative embodiment—not shown—the cavities 21 may be closed at the side of the tray body 20 that faces away from the drop plate 3, in which case medicine dispensing device 1 can be inverted to receive the medicine items via the drop openings 31 of the drop plate 3 into the cavities 21. The drop plate 3 is then moved into the hold position to close the cavities 21 and the medicine dispensing device 1 is turned back to its original orientation. From that moment, the medicine dispensing device 1 can dispense the medicine items from the cavities 21 through the drop openings 31 in the same way as previously described.

[0065] As shown in FIGS. 1 and 3, the medicine dispensing device 1 further comprises one or more retaining members 4 for retaining the drop plate 3 relative to the tray 2 in the drop direction D when the drop plate 3 is in the dispensing path X between the first endpoint E1 and the second endpoint E2. In this exemplary embodiment, the one or more retaining members 4 are arranged for coupling, connecting and/or retaining the drop plate 3 directly to the tray 2, i.e. without additional means such as a frame. The one or more retaining members 4 can be located in a central area of the tray 2 and/or the drop plate 3, for example, spaced apart from the edges thereof, to prevent deflection of said drop plate 3 relative to the tray 2, in particular when said drop plate 3 is relative large and thin.

[0066] As best seen in FIG. 1, each retaining member 4 comprises a male element 5 associated with one of the tray 2 and the drop plate 3 and a female element 6 formed in the other of the tray 2 and the drop plate 3. The male element 5 and the female element 6 can be arranged to engage with each other through some form of mechanical interlock, e.g., a form-lock.

[0067] In particular, the female element 6 comprises a retaining slot 61 extending parallel to the sliding direction S and a keyhole 62 that is arranged in communication with said retaining slot 61 at one end of the retaining slot 61 for receiving the male element 5 from the retaining slot 61. The dispensing path X extends along or is defined by at least a part of the retaining slot 61. The dispensing path X may however be shorter than the length of the retaining slot 61, e.g., when it is limited in movement relative to the tray 2 by suitable limiting elements (not shown). As shown in FIG. 3, the male element 5 comprises a stem 51 that fits through the retaining slot 61 in the drop direction D and a head 52 at one end of the stem 51 that fits through the female element only at the keyhole 62. Consequently, the keyhole 62 corresponds to or defines the release position P.

[0068] The head 52 can have a head dimension H in the sliding direction S and the release position P is spaced apart from the dispensing path X over a distance that is equal to or greater than half the head dimension H, to prevent accidental and/or unintentional release of the drop plate 3 from the tray 2. The release position P can be spaced apart from the first endpoint E1 of the dispensing path X in the sliding direction S over at least three millimeters, for example, at least five millimeters.

[0069] In this exemplary embodiment, the female element 6 is formed in the drop plate 3 and the male element 5 is connected to, coupled with or associated with the tray 2.

[0070] The male element 5, when engaged with the female element 6, is arranged to remain engaged with the female element 6 as long as the drop plate 3 is in the dispensing path X. However, as briefly discussed before, the drop plate 3 further slidable in a release direction R outside of the dispensing path X, in particular beyond the first endpoint E1, and more in particular parallel to the sliding direction S within the clearance W as shown in FIG. 3. As such, the drop plate 3 may be slid into a release position P in which one or more retaining elements 4 are arranged to release the drop plate 3 from the tray 2 in the drop direction D. In particular, the male element 5 is arranged to disengage from the female element 6 when the drop plate 3 is in the release position P. More in particular, the release position P corresponds to the position in which the head 52 of the male element 5 is aligned with the keyhole 62 of the female element 6.

[0071] It is noted that the drop plate 3 still at least partially overlaps with the tray 2 in the release direction R when the drop plate 3 is in the release position P, as for example shown in FIG. 6. This allows for the drop plate 3 to be released from the tray 2 without sliding the drop plate 3 completely clear of the tray 2 in the release direction R. In other words, the drop plate 3 only has to be moved over a small distance beyond the dispensing path X to be released from the tray 2.

[0072] The one or more retaining members 4 are arranged for releasing the drop plate 3 from the tray 2 in the drop direction D so that the mechanical interlock between the male element 5 and female element 6 can be terminated quickly and effectively. More specifically, the head 52 of the male element 5 can be retracted through the keyhole 62 of the female element 6 in a direction parallel to the drop direction D to release the drop plate 3 from the tray 2.

[0073] In addition or as an alternative to said spacing, the medicine dispensing device 1 is provided with one or more blocking members 7, as shown in FIGS. 1 and 4, for blocking and unblocking the drop plate 3 from sliding in the release direction R outside of the dispensing path X, in particular beyond the first endpoint E1 of the dispensing path X, towards and/or into the release position P. Each blocking member 7 can comprise a stop element 71 associated with one of the tray 2 and the drop plate 3 and a catch 72 formed in or by the other of the tray 2 and the drop plate 3. In this exemplary embodiment, the stop element 71 is associated with, connected to or formed by the tray 2 and the catch 72 is associated with, formed in or formed by the drop plate 3. The stop element 71 is arranged to abut the catch 72 in the release direction R when the drop plate 3 is in the first endpoint E1 of the dispensing path X.

[0074] The stop element 71 can be movable between a block position in which the stop element 71 engages with the catch 72 and an unblock position in which the stop element 71 is disengaged from the catch 72. Each blocking member 7 can further comprise a block bias element 73 for biasing the stop element 71 from the unblock position into the block position.

[0075] In some embodiments, the stop element 71 is manually movable, e.g., without tools, against the bias of the block bias element 73 from the block position into the unblock position.

[0076] The catch 72 may be conveniently shaped as a catch slot that extends in the sliding direction S. The catch slot can be positioned in such a way that it receives or accommodates the stop element 71 when the drop plate 3 is at any position along the dispensing path X. In particular, the stop element 71 is biased to automatically move into a block position in the catch slot as soon as the drop plate 3 is in the dispensing path X.

[0077] As best seen in FIG. 4, the stop element 71 and the block bias element 72 are integrally formed. In this exemplary embodiment, the block bias element 72 is a leaf spring that is directly connected to or integral with the stop element 71.

[0078] In this exemplary embodiment, the tray 2 is provided with one or more blocking member accommodation recesses 23 for accommodating at least a part of a respective one of the one or more blocking members 7, in particular the block bias element 72 thereof.

[0079] As shown in FIGS. 1, 5 and 6, the medicine dispensing device 1 further comprises one or more slide biasing members 8 for biasing the drop plate 3 from the drop position into the hold position. Each slide biasing member 8 can comprise a spring 80 that acts on one or both of the tray 2 and the drop plate 3 in the sliding direction S. In this exemplary embodiment, the tray 2 is provided with one or more slide bias slots 24 for accommodating at least a part of a respective one of the one or more slide biasing members 8. Each slide bias slot 24 extends in or parallel to the sliding direction S.

[0080] In this exemplary embodiment, each slide biasing member 8 further comprises a pin 81 that is arranged to engage the drop plate 3, as shown in FIG. 5. The drop plate 3 is provided with a corresponding pin aperture 33 that is suitable dimensioned to receive and retain said pin 81 in the drop direction D. As shown in FIG. 6, the pin aperture 33 can be suitably positioned in the drop plate 3 such that the pin 81 is automatically aligned with the pin aperture 33 in the drop direction D when the drop plate 3 is placed in the release position P relative to the tray 2. In particular, the corresponding slide bias slot 24 in the tray 2 is of such a length that the pin 81 stays behind in the slide bias slot 24 resting against one end of said slide bias slot 24 when the drop plate 3 is released from the tray 2, wherein said one end of the bias slot 24 corresponds to or is aligned with the pin aperture 33 in the drop direction D. Hence, no additional actions are required to couple the slide biasing member 8 with the drop plate 3, other than just simply placing the drop plate 3 in the release position P and moving it into the dispensing path X to tension the spring 80.

[0081] The combination of the slide biasing member 8, the blocking member 7 means that after the drop plate 3 has been moved against the bias of the slide biasing member 8 into the drop position to drop the medicine items, it can be biased to automatically return to the hold position where it is blocked by the blocking member 7 against further sliding towards the release position P. Optionally, the slide biasing member 8 still biases the drop plate 3 in the hold position so that, when the drop plate 3 is unblocked, the bias from the slide biasing member 8 automatically causes the drop plate 3 to move towards and/or into the release position P.

[0082] A method for dispensing medicine items using the aforementioned medicine dispensing device 1 will be elucidated below with reference to FIGS. 1-6.

[0083] During a method of dispensing medicine, the drop plate 3 and/or the tray 2 need to be cleaned regularly, e.g., at specified intervals. The method therefore comprises the step of sliding the drop plate 3 in the release direction R into the release position P outside of the dispensing path X, in particular beyond the first endpoint E1 of the dispensing path X, and releasing the drop plate 3 from the tray 2 in said release position P. The sliding of the drop plate 3 into the release position P is an act that can be performed relatively easily as an extension of the sliding that already occurs within the dispensing path X. There is no need to loosen and remove each retaining member 7 individually. The sliding of the drop plate 3 into the release position P can be effectuated in the same way as the sliding of the drop plate 3 within the dispensing path X, e.g., manually without the need to use tools. Once the drop plate 3 is released from the tray 2, the drop plate 3 and/or the tray 2 can be cleaned.

[0084] The drop plate 3 and the tray 2 can be put back together again in the reverse order with the same ease, e.g., by positioning the drop plate in the release position relative to the tray and by subsequently sliding the drop plate in the sliding direction from the release position into any position within the dispensing path.

[0085] When the drop plate 3 is blocked by the one or more blocking members 7 in the hold position, the method comprises unblocking the drop plate 3 prior to the sliding of the drop plate 3 into the release position P. The unblocking may be performed manually. Conveniently, when the drop plate 3 is biased to move in the sliding direction S towards the release position P, then the drop plate 3 merely requires manual unblocking and the bias on the drop plate 3 will do the rest.

[0086] FIGS. 7 and 8 show an alternative medicine dispensing device 101 according to a second embodiment that differs from the previously discussed medicine dispensing device 1 in that it is provided with a frame 109 to receive and/or hold the tray 2 and in that it comprises a slightly modified drop plate 103 that is arranged to be connected, coupled and/or retained directly to the frame 109 instead of the tray 2. Hence, the drop plate 3 is still retained relative to the tray 2, yet indirectly via the frame 109.

[0087] In particular, the alternative medicine dispensing device 101 comprises one or more alternative retaining members 104 for retaining the drop plate 103 directly to the frame 109. For this purpose, the alternative retaining members 104 are moved to a position close to the frame 109 to engage said frame 109. In particular, each alternative retaining members 104 comprises a male element 105 and a female element 106 similar to the ones previously described, yet positioned close to or at the frame 109 to facilitate the direct retaining of the drop plate 103 to the frame 109. In this particular embodiment, the male element 105 is provided at the frame 109 and the female element 106 is provided at or formed in the drop plate 103.

[0088] The frame 109 can be provided with one or more flanges 191, 192 that act as a sliding guide for the sliding movement of the drop plate 103 relative to the tray 2. The one or more alternative retaining members 104 may be provided at the location of said one or more flanges 191, 192.

[0089] FIG. 9 shows a further alternative medicine dispensing device 201 according to a third embodiment of the invention that differs from the previously discussed medicine dispensing devices 1, 101 in that it features a drop plate 203 that is arranged to be moved in a release direction R that is transverse or perpendicular to said sliding direction S. Consequently, the release position P of the drop plate 203 is located outside of the dispensing path X in a direction transverse or perpendicular to said dispensing path X.

[0090] In this particular example, the further alternative medicine dispensing device 201 comprises one or more retaining members 204 that differs from the previously discussed retaining members 4, 104 in that its female element 206 is provided with a retaining slot 261 extending in the sliding direction S and a keyhole 262 to the side of the retaining slot 261 in a direction parallel to the release direction R. The keyhole 262 communicates with the retaining slot 261 to receive the male element 5 when the drop plate 203 is moved in the release direction R. In this exemplary embodiment, the keyhole 262 is located at a position alongside the retaining slot 261 somewhere along the length of the retaining slot 261, e.g., at an intermediate position between the first endpoint E1 and the second endpoint E2. Alternatively, the keyhole 262 may be arranged alongside the retaining slot 261 at or near one of the ends of the retaining slot 261.

[0091] In the further alternative dispensing device 201 according to the third embodiment of the invention, the drop plate 203 can thus be moved out of the dispensing path X when the male element 5 is aligned with the keyhole 262 in a direction parallel to the release direction R.

[0092] To prevent that the drop plate 203 is accidentally released from the tray 2 when its male element 5 is aligned with the keyhole 262, the further alternative dispensing device 201 is provided with one or more blocking members 207 that are movable into a block position for blocking the movement of the drop plate 203 in the release direction R. The one or more blocking members 207 can be manually moved into an unblock position. The one or more blocking members 207 can be biased to move into the block position. In this exemplary embodiment, at least one of the one or more blocking members 207 is movable into a block position between the retaining slot 261 and the keyhole 262 of a respective one of the retaining members 204 to block access to the keyhole 262 from the retaining slot 261. Effectively, this prevents that the drop plate 203 can be moved in the release direction R.

[0093] Optionally, the drop plate 203 may be biased to move from the drop position into the hold position, e.g., with a slide biasing member similar to the slide biasing member as previously described, provided that said slide biasing member does not interfere with the transverse movement in the release direction R. The drop plate 203 may for example be provided with a slot-shaped aperture extending in the release direction R to receive the pin of the slide biasing member. Alternatively, the slide biasing member may have an alternative rest position offset in the release direction R, yet aligned with the pin aperture when the drop plate 203 is in the release position P.

[0094] FIG. 10 shows a bottom view of a further alternative medicine dispensing device 301 according to a fourth embodiment of the invention. The further alternative medicine dispensing device 301 has a frame 309 similar to the frame 109 as shown in FIGS. 7 and 8, to receive and/or hold the tray 2 and a drop plate 303 that is arranged to be connected, coupled and/or retained directly to the frame 309 instead of the tray 2. The further alternative medicine dispensing device 301 differs from the previously discussed medicine dispensing devices 1, 101, 201 in that it features one or more alternative retaining members 304 different from the slot/keyhole interaction as described in the previous embodiments.

[0095] In particular, each alternative retaining members 304 still comprises a male element 305 and a female element 306. However, the male element 305 can be formed as a cam while the female element 306 can be formed as a recess that is aligned with the male element 305 in the drop direction D when the drop plate 303 is moved into the release position P. In this exemplary embodiment, the male element 305 is provided at the drop plate 303 and the female element 306 is a recess in the frame 309. The frame 309 may be provided with flanges or grooves 391, 392 that retain the male element 305 to the frame 309 in the drop direction D as long as the drop plate 303 is not in the release position P.

[0096] FIG. 11 shows a top perspective view of a medicine dispensing device 1 tray 2 with a cover 400 on it; FIG. 12 shows a top view of the tray 2; FIG. 13 shows a cross-sectional view of the tray along line A-A; and FIG. 14 shows a view of the tray 2 with cover 400 removed.

[0097] Tray 2 can be the top or receiving side of the dispensing device 1, and could have any of the bottom embodiments as discussed in relation to FIGS. 1-10, the embodiment shown and discussed in relation to FIGS. 16-18, or other embodiments.

[0098] Tray 2 includes storage cavities 21 for receiving one or more medicine items, as previously discussed in relation to FIG. 2. Storage cavities 21 are shown in this embodiment as having a rectangular shape with two opposing corners having a more rounded off shape. The configuration shown includes the storage cavities 21 having mirrored configurations and placements along centre lines running in each of the width and length directions of the tray. In the embodiment shown, tray 2 includes 64 cavities, though other trays could have more or fewer cavities 21. In addition, cavities could have a different shape and/or configuration in different embodiments.

[0099] Tray 2 includes front 402, back 404, and sides 406, 408. Each of front 402 and back 404 extend generally in a straight line though with center front and back recessed portions 412, 414 which are recessed toward the middle of tray 2. In front 402, pull member 32 (discussed in relation to FIG. 3) sits in front recessed portion 412.

[0100] Tray also includes an outer lip 416 extending around an upper surface of tray 2 in which cavities 21 sit, generally extending around the outer edge of tray 2 and which forms a ledge 418 around the upper surface of tray 2, except at back recessed portion 414. At back recessed portion 414, lip 416 is interrupted such that there is no lip 416 and no ledge 418. Ledge 418 forms the surface for receiving and holding cover 400 in place over tray 2 cavities 21. Cover 400 is generally shaped to fit just within ledge 418 of tray 2, though can vary in some embodiments. Ledge 418 does not extend around back recessed portion 414 to allow tray 2 to be inserted into another device or machine (e.g., a filling or emptying station) for emptying and/or filling tray 2. Back recessed portion 414 can help to guide the tray 2 for alignment with and/or proper insertion into another device.

[0101] By leaving back recessed portion without the outer lip 416 and ledge 418, a user can easily see if the tray is being inserted the wrong way. For example, if a user tried to insert the front side 402 of tray 2 into another device instead of the back side 404, lip 416 and ledge 418 at front recessed portion 412 would prevent full insertion and/or alignment thereby alerting the user that the tray 2 needed to be removed and turned around for correct insertion.

[0102] Ledge 418 is typically similar in height to the thickness of the cover 410 (for example, 3 mm), thereby forming a generally smooth tray 2 upper surface when cover 400 is connected. This also helps to ensure that tray 2 is not inserted into or connected with another device while cover 400 is still on tray 2. When cover 400 is connected to tray as shown in FIG. 11, cover 400 forms a ledge around back center recessed portion 414. This would also prevent full insertion into and/or alignment with another device (e.g., a filling station), alerting the user that the cover 400 has not yet been removed and needs to prior to insertion and/or connection with another device, for example, to allow medicines to be place into cavities 21.

[0103] Cover 400 is typically a transparent or semi-transparent plate, and can be further secured to tray 2 by rotatable clips 410 on sides 406 and 408. Cover 400 is generally symmetric along each of long central axis A.sub.L and short central axis A.sub.S, and sized to fit just inside ledge 418 of tray. This allows for easy and quick placement of cover 400, as a user does not have to rotate to find the proper alignment position, and can place in any position as long as the long axis aligns with the long axis of tray 2. Ledge 418 helps to guide and secure cover 400 into the proper position to ensure it stays in position to cover cavities 21, thereby ensuring any medicines stay within cavities 21 and remain protected, for example, from falling and/or environmental conditions.

[0104] Clips 410 are shown in cross-sectional views in FIGS. 18A-18B, and can also function as handles for holding the tray 2. Clips 410 rotate outward around a spring pivot 419, which is generally S-shaped, and includes a flat portion 420, as shown in FIGS. 15A-15B. Pivot 419 rotates between a closed position shown in FIG. 15A, and an open position shown in FIG. 15B. In a closed position, clips 410 extend partially over cover 400, with pivot 419 supported to stay in the closed position by flat surface 420 aligning with lower flat surface 422. Clip 410 and pivot 419 can then rotate from the closed position to the open position shown in FIG. 15B, where cover 400 can be removed from tray 2. Pivot 419 rotates in the opening direction, and flat portion 420 snaps clip 410 into the open position, (and then holds clip 410 in the open position) by flat portion 420 aligning with side flat surface 424. S-shaped pivot 419 acts as a spring, exerting an outward force which helps pivot 419 and therefore clip 410 snap and stay in either an open or closed position. Additionally, the pivot axis of the clip 410 is positioned below the projection of clip 410 which overlies cover 400. Thus, the edge of cover 400 lays beyond the pivot axis of the clip 410. Therefor the upper part of clip 410 needs to be slightly deformed when moving from the closed position to the open position for passing the edge of cover 400 during a pivoting movement. Thus, the snapping effect of the clip is achieved by pivot 419 and by the edge of the cover 400.

[0105] Thus, clips 410 with pivots 419 are a simple yet secure way to connect cover 400 to tray 2, while allowing for easy removal without a lot of complicated parts. The simple pivot 419 design with part of clips 410 extending over cover 400 allows for easy positioning and opening and closing of clips 410 with a minimum number of parts. Additionally, the securing of cover within ledge 418 and by clips 410 extending at least partially over cover allows for a planar, symmetric design which does not need additional holes, notches or other features to ensure retention and alignment. This can make it such that cover is easier to manufacture and/or replace when necessary.

[0106] The design of tray 2, with lip 416, ledge 418, clips 410, and front and back recessed portions 412, 414 results in an aesthetically pleasing, more simplified tray which also helps to reduce human error (e.g., in insertion of tray, connecting of cover). The use of lip 416 and ledge 418 which extends generally around the edge tray 2 with an interruption at the back recessed portion 414 helps to reduce errors, for example, associated with insertion of tray 2 into another machine or device (e.g., filling and/or emptying station) in the wrong direction. Ledge 418 would block insertion in the wrong direction, thereby alerting a user to the error.

[0107] The use of a symmetric cover 400 which is complementary in shape to the ledge 418 (only a bit smaller) allows for a user to easily place cover 400 on tray 2 without having to arrange for the correct alignment as there is no “front” or “back” edge of cover. Thus, cover 400 can be connected over tray 2 at the orientation shown in FIG. 11, or rotated 180 degrees. The use of a cover 400 which is similar in height to ledge 418 helps to prevent accidental insertion of tray 2 into a filling or emptying device with cover 400 still on (thereby preventing filling and/or emptying) as cover 400 then forms a ledge which blocks insertion when connected. Clips 410 provide a simple yet effective way to secure cover 400 to tray 2, thereby ensuring medicines stay within cavities 21, yet which is also easily removable when desired by simply rotating clips 410 to an open position. The securing of cover 400 with clips 410 extending partially over also allows for a more simple cover which doesn't need additional connection or alignment features, which can save on manufacturing time and expenses.

[0108] FIGS. 16-18 show a bottom views of the tray 2 of FIG. 11, in stages of closed (FIG. 16), open (FIG. 17) and release (FIG. 18). The tray 2 shown works in much the same manner as described above, with drop plate 3 being slideable to move from a closed position to an open position, and to the release position shown in FIG. 18 where drop plate 3 can be completely removed from tray 2, for example for cleaning, as discussed in detail in relation to the embodiments previously described and will not be further discussed here. Pull member 32 can be used to easily facilitate this movement.

[0109] Tray bottom also includes grips 430, which can be one or more indentations, channels and/or cavities extending into the bottom surface of tray 2. Such grips 430 allow for a user to easily grip the tray 2 for sliding and/or other handling movements during use of the tray. This can be especially useful for removing from another device, for example, a filling or emptying station.

[0110] Tray bottom also includes one or more alignment features 432, which can be one or more grooves, holes, protrusions, channels or other physical features which can help with ensuring that tray 2 is properly aligned in a filling and/or emptying station. Alignment features 432 can interact with other complementary features on another device to ensure that tray 2 is in a proper position for filling and/or emptying medicines into or from cavities 21.

[0111] Such a filling station can be, for example, the filling station shown and described in WO2021/228603, “Docking station and method for loading a medicine transport plated,” filed 3 May 2021, which is hereby incorporated by reference, or another type of filling station. Such a filling station could be a manual filling (as in WO2021/228603) or an automatic filling station, where, for example, a robot or other machine places medicines into cavities 21. Then the device with at least some cavities 21 with medicines inside can be removed from the filling station (manually or automatically), have cover 400 placed on tray 2, and transported to another machine or device for emptying, removing cover 400 before inserting into the emptying machine or device. Any and/or all of these steps could also be done manually, or with automation, for example, a robot or other conveying device (e.g., conveyor belt) transporting the tray from the filling station to an emptying device, such as WO2014/081286 “Device and method for dispensing and packing solid substances”, filed 19 Aug. 2013.

[0112] FIG. 19 shows a partially transparent view of a corner of tray 2 with an identification device 440, for example an RFID chip. Identification device 440 is located in a back corner of tray 2, enabling for easy reading of the identification device when connected to another device or machine, for example, a filling station. The identification device can include information about the tray 2, medicines within the tray or other information, and is a simple way to ensure that the correct tray 2 and/or medicines are in use at any time.
