Storage container for a storage and dispensing station for pharmaceuticals
A storage container for a storage and dispensing station for pharmaceuticals is provided. The storage container includes a housing, which encloses a receptacle chamber having a guide section, wherein an inner wall of the guide section defines a circular-cylindrical guide chamber. A singulating unit is arranged in the guide section of the housing having a central axis of rotation. The singulating unit has a main section and multiple projections, wherein each projection has two end sections and a middle section. One pharmaceutical duct is formed between each two end sections of adjacent projections, wherein the middle sections of the projections are recessed and one or both end sections of each projection bear on the wall of the guide section. Gaps between the singulating unit and the inner wall allow pharmaceutical dust to fall through to avoid pharmaceutical dust formed during singulation causing increased friction between the singulating unit and the wall of the storage container.
1. A storage container for pharmaceutical portions, comprising:
a housing enclosing a receptacle chamber for pharmaceutical portions, the housing comprising a guide section and a bottom face, wherein an inner wall of the guide section defines a circular-cylindrical guide chamber and wherein the bottom face has a dispensing opening;
a singulating unit arranged in the guide section of the housing and having a central axis of rotation, the singulating unit when viewed from above comprising a main section and a plurality of projections arranged around the main section, wherein each projection has a first end section outer wall, a second end section outer wall and a middle section outer wall collectively forming a single radial surface disposed in a parallel plane to the bottom face and laterally and circumferentially in perpendicular relation to a central axis of rotation, and a plurality of pharmaceutical ducts, wherein each pharmaceutical duct is formed between adjacent end sections of adjacent projections; and
wherein for each projection the middle section outer wall and the first end section outer wall are radially recessed the same distance and closer to the central axis of rotation than the second end section outer wall the second end section outer wall formed such that its outermost surface bears on the inner wall of the guide section.
2. The storage container of claim 1 , wherein the second end section outer walls having lateral surfaces that bear on the wall of the guide section are distributed uniformly around the central axis of rotation.
3. The storage container of claim 1 , wherein the second end section outer walls of the projections bearing on the wall of the guide section are distributed uniformly over the singulating unit.
4. The storage container of claim 1 , wherein the projections have an anti-adhesive coating at least in a region of the middle section outer wall facing toward the wall of the guide section.
5. The storage container of claim 1 , wherein the singulating unit has a conical surface comprising a plurality of depressions.
6. The storage container of claim 5 , wherein the plurality of depressions are aligned at the pharmaceutical ducts.
7. The storage container of claim 1 , wherein the main section has setbacks above the pharmaceutical ducts.
8. The storage container of claim 1 , wherein the singulating unit has four projections and four pharmaceutical ducts.
9. The storage container of claim 1 , wherein the singulating unit has three projections and three pharmaceutical ducts.
10. The storage container of claim 1 , wherein a vertical height of each of the plurality of projections and each of the plurality of pharmaceutical ducts is the same.
11. A storage container for pharmaceutical portions, comprising:
a housing enclosing a receptacle chamber for pharmaceutical portions, the housing comprising:
a guide section having an inner wall defining a circular-cylindrical guide chamber; and
a bottom face having a dispensing opening; and
a singulating unit disposed in the guide section, the singulating unit comprising:
a plurality of projections disposed on a common circumferential plane, each projection having two end sections and a middle section; and
a plurality of pharmaceutical ducts, each pharmaceutical duct disposed between two adjacent end sections of adjacent projections,
wherein for each projection, the middle section is recessed radially in relation to the corresponding end sections and an outer surface of each end section bears on the inner wall of the guide section.
12. The storage container of claim 11 , wherein the end sections of the projections are distributed uniformly over the singulating unit.
13. The storage container of claim 11 , wherein the projections have an anti-adhesive coating in at least a portion of the middle section on a lateral surface facing toward the wall.
14. The storage container of claim 11 , wherein the singulating unit has a conical surface comprising a plurality of depressions aligned at the pharmaceutical ducts.
15. A storage container for pharmaceutical portions, comprising:
a housing enclosing a receptacle chamber for pharmaceutical portions, the housing comprising:
a guide section having an inner wall defining a circular-cylindrical guide chamber; and
a bottom face having a dispensing opening; and
a singulating unit disposed in the guide section, the singulating unit when viewed from above comprising:
a plurality of projections disposed circumferentially in relation to a central axis of rotation, each projection having a first end section outer wall, a second end section outer wall and a middle section outer wall collectively forming a single radial surface disposed in parallel to the bottom face, the radial surface being laterally, circumferentially and perpendicularly oriented to the central axis of rotation; and
a plurality of pharmaceutical ducts, each pharmaceutical duct disposed between adjacent end sections of adjacent projections,
wherein for each projection, the middle section outer wall and the first end section outer wall are recessed radially closer to the central axis of rotation than the second end section outer wall and an outer surface of the second end section outer wall bears on the inner wall of the guide section, and wherein the middle section outer wall is recessed radially equally to the central axis of rotation as the first end section outer wall.
16. The storage container of claim 15 , wherein the second end section outer walls of the projections are distributed uniformly over the singulating unit.
17. The storage container of claim 15 , wherein the projections have an anti-adhesive coating in at least a portion of the middle section outer wall facing toward the wall of the guide section.
18. The storage container of claim 15 , wherein the singulating unit has a conical surface comprising a plurality of depressions aligned at the pharmaceutical ducts.
