Abstract

Storage and dispensing devices are provided, which include a housing, a rotor disposed in the housing, a dispensing opening disposed in a bottom surface of the housing and configured to receive an individual medicament portion when a first channel of the rotor is aligned with the dispensing opening, and a recess disposed in the bottom surface of the housing and at least partially surrounding an axis of the rotor. Additional storage and dispensing devices are also provided.

First claim

What is claimed:

1. A storage and dispensing device, comprising:
a housing;
a rotor disposed in the housing;
a dispensing opening disposed in a bottom surface of the housing and configured to receive an individual medicament portion when a first channel of the rotor is aligned with the dispensing opening; and
a recess disposed in the bottom surface of the housing and at least partially surrounding an axis of the rotor,
wherein the bottom surface comprises a protrusion at least partially surrounding the axis of the rotor, the protrusion configured to prevent contamination particles from reaching the axis of the rotor.

2. The storage and dispensing device of claim 1 , wherein a plurality of webs on the rotor define a plurality of channels including the first channel, the plurality of webs overlapping a contact area on the bottom surface, the contact area being exposed to the medicament portions through the channels, and wherein the dispensing opening intersects the contact area to deliver the individual medicament portion as the medicament portions are swept by the webs upon a rotation of the rotor.

3. The storage and dispensing device of claim 1 , further comprising a retention component configured to engage with a channel aligned with the dispensing opening and to prevent a second individual medicament portion from being dispensed through the channel aligned with the dispensing opening.

4. The storage and dispensing device of claim 1 , wherein each of a plurality of channels of the rotor, including the first channel, comprises a first opening facing a receiving space of the housing and a second opening facing the bottom surface, and wherein the second opening is associated with a contact area on the bottom surface, over which contact area the medicament portions are guided upon a movement of the rotor.

5. The storage and dispensing device of claim 1 , wherein the rotor is arranged to provide a gap between a bottom of the rotor and the bottom surface, through which gap contamination particles can pass.

6. The storage and dispensing device of claim 1 , wherein at least a portion of the bottom surface is coated with a non-stick coating.

7. A storage and dispensing device, comprising:
a housing;
a rotor disposed in the housing;
a dispensing opening disposed in a bottom surface of the housing and configured to receive an individual medicament portion when a first channel of the rotor is aligned with the dispensing opening;
a recess disposed in the bottom surface of the housing;
at least one cleaning agent disposed on the rotor and configured to move contamination particles to the recess when the rotor turns; and
a gap between a bottom of the rotor and the bottom surface,
wherein the bottom surface comprises a protrusion at least partially surrounding an axis of the rotor, the protrusion configured to prevent contamination particles from reaching the axis of the rotor.

8. The storage and dispensing device of claim 7 , wherein a plurality of webs on the rotor define a plurality of channels including the first channel, the plurality of webs overlapping a contact area on the bottom surface, the contact area being exposed to the medicament portions through the channels, and wherein the dispensing opening intersects the contact area to deliver the individual medicament portion as the medicament portions are swept by the webs upon a rotation of the rotor.

9. The storage and dispensing device of claim 7 , wherein each of a plurality of channels of the rotor, including the first channel, comprises a first opening facing a receiving space of the housing and a second opening facing the bottom surface, and wherein the second opening is associated with a contact area on the bottom surface, over which contact area the medicament portions are guided upon a movement of the rotor.

10. The storage and dispensing device of claim 7 , wherein the rotor is arranged to provide a gap between a bottom of the rotor and the bottom surface, through which gap contamination particles can pass.

11. The storage and dispensing device of claim 7 , wherein at least a portion of the bottom surface is coated with a non-stick coating.

12. A storage and dispensing device, comprising:
a housing;
a rotor disposed in the housing;
a dispensing opening disposed in a bottom surface of the housing and configured to receive an individual medicament portion when a first channel of the rotor is aligned with the dispensing opening;
a recess disposed in the bottom surface of the housing; and one of:
a stop element comprising an elastic arm configured to engage with a toothed profile formed in an axis of the rotor and to avoid an unintended rotation of the rotor; and
a vibration device mechanically coupled to a contact area adjacent to the bottom surface, the vibration device configured to expose the housing to a vibration.

13. The storage and dispensing device of claim 12 , wherein a plurality of webs on the rotor define a plurality of channels including the first channel, the plurality of webs overlapping a contact area on the bottom surface, the contact area being exposed to the medicament portions through the channels, and wherein the dispensing opening intersects the contact area to deliver the individual medicament portion as the medicament portions are swept by the webs upon a rotation of the rotor.

14. The storage and dispensing device of claim 12 , wherein each of a plurality of channels of the rotor, including the first channel, comprises a first opening facing a receiving space of the housing and a second opening facing the bottom surface, and wherein the second opening is associated with a contact area on the bottom surface, over which contact area the medicament portions are guided upon a movement of the rotor.

15. The storage and dispensing device of claim 12 , wherein the rotor is arranged to provide a gap between a bottom of the rotor and the bottom surface, through which gap contamination particles can pass.

16. The storage and dispensing device of claim 12 , wherein the bottom surface comprises a protrusion at least partially surrounding the axis of the rotor, the protrusion configured to prevent contamination particles from reaching the axis of the rotor.

17. The storage and dispensing device of claim 12 , wherein at least a portion of the bottom surface is coated with a non-stick coating.

18. The storage and dispensing device of claim 12 , further comprising a retention component configured to engage with a channel aligned with the dispensing opening.
