Abstract

The tablet dispenser comprises a drawer, which is adapted to be extracted into engagement with a stop from one end of a tubular protective housing and in its extracted position is adapted to be supplied with a columnlike stack of tablets. The tablets can be advanced as far as to an ejector, which is mounted on that portion of the drawer which protrudes from the protective housing. The ejector is operable to eject each tablet transversely to the longitudinal direction of the stack while the tablet is guided between spaced apart side guides. The side guides consist of clamping holders, which protrude beyond the end of the tubular protective housing and which receive one tablet at a time. Each tablet can be pushed between the clamping holders in that the drawer is raised. The drawer is provided near its bottom end with a foot for supporting the tablet stack. A tilting of the tablets in the housing is prevented by longitidinal guides.

Claims

1. In a tablet dispenser comprising

a tubular protective housing having a top end and provided at said top end with inwardly protruding detent means,

a drawer, which is axially slidably mounted in said housing and protrudes from said housing at said top end and is adapted to be upwardly extracted from said housing to a top position, in which said drawer engages said detent means,

a columnlike stack of tablets, which is contained in said drawer and comprises a plurality of tablets, each of which is in sliding contact with said drawer and said protective housing, said drawer being adapted to receive such a stack of tablets when said drawer is in said top position,

two mutually opposite side guides, which are mounted on said housing and extend above said top end thereof and are adapted to receive one of said tablets from said stack and to guide said one tablet transversely to the axis of said drawer, and

an ejector, which is movably mounted in said drawer outside said protective housing and is operable to eject said one tablet on one side of said drawer transversely to the axis of said drawer when said one tablet is disposed between said side guides,

the improvement residing in that

said side guides comprise laterally spaced apart clamping holders, which are connected to said housing and extend above said top end thereof and hold said one tablet between them,

said drawer has a bottom end disposed in said housing and near said bottom end is provided with a foot, which supports said stack of tablets, and

after the ejection of said one tablet said drawer is adapted to be raised in said housing to move the uppermost tablet of said stack to a position between said clamping holders.

2. The improvement set forth in claim 1, wherein

said drawer is formed with longitudinally extending, continuous openings and

said housing is provided with longitudinal guides, which extend through said longitudinal openings and engage said stack of tablets to prevent a tilting of said tablets in said drawer.

3. The improvement set forth in claim 2, wherein said longitudinal guides are in positive engagement with said tablets.

4. The improvement set forth in claim 2, wherein said longitudinal guides engage all tablets of said stack in said drawer.

5. The improvement set forth in claim 1 as applied to a tablet dispenser in which said tablets are basically rectangular, wherein

said one tablet has a forward portion extending between said clamping holders only to approximately the length center of said uppermost tablet, and a rear portion laterally protruding from said clamping holders toward the other side of said drawer,

said housing comprises housing wall portions which laterally guide said rear portion of said one tablet and corresponding rear portions of the tablets of said stack,

said drawer comprises drawer wall portions which extend from said housing wall portions and guide said tablets of said stack at side portions other than said rear portions, and

said housing is provided with additional longitudinal guides in sliding contact with opposite end faces of said tablets.

6. The improvement set forth in claim 5, wherein said additional longitudinal guides comprise rakes.

7. The improvement set forth in claim 1, wherein

said clamping holders comprise resilient tongues, which are integrally formed with said housing and resiliently biased toward each other and have confronting sides, which are formed with grooves for retaining and guiding said one tablet.

8. The improvement set forth in claim 1, wherein

a guide member is mounted in said drawer at said bottom end of said drawer at a distance below said foot,

said guide member and said foot have been inserted into said drawer through said top end of said protective housing, and

said clamping holders are arranged to prevent an extraction of said foot and said guide member out of said protective housing.

9. The improvement set forth in claim 5, wherein said additional longitudinal guides are spaced a distance apart which is smaller than the length of each tablet whereby the additional longitudinal guides form grooves in the end faces of said tablets.
