Patent ID: 8695483

Claim:
A holder assembly ( 1 ) for a powdered ingredient ( 4 ) for preparing an instant drink, comprising: a holder; a conveyor screw ( 6 ) provided in the holder ( 5 ) along the base ( 30 ) of the holder; an outflow channel ( 7 ) provided on the holder ( 5 ) for dispensing that ingredient ( 4 ), an end ( 8 ) of the conveyor screw ( 6 ) protruding into the outflow channel ( 7 ), the outflow channel ( 7 ) extending in a longitudinal direction (L) of the conveyor screw ( 6 ); a threshold plate ( 9 ) which extends transversely to the longitudinal direction of the conveyor screw ( 6 ) and which is attached in the outflow channel ( 7 ) downstream of that one end ( 8 ) of the conveyor screw ( 6 ); a shut-off valve ( 10 ) arranged at an outflow opening of the outflow channel ( 7 ), the outflow opening being situated at a longitudinal end of the outflow channel ( 7 ), near the threshold plate ( 9 ); wherein the shut-off valve ( 10 ) comprises a shut-off body ( 11 ) which shut-off valve ( 10 ) and shut-off body ( 11 ) can be moved back and forth over the longitudinal end of the outflow channel ( 7 ) comprising the outflow opening, by hand, in the longitudinal direction (L) of the conveyor screw ( 6 ) between a release position ( FIG. 4B and FIG. 4C ) and a shut-off position ( FIG. 4A ); the shut-off body ( 11 ) being located in the release position on the downstream side of the threshold plate ( 9 ) and the outflow opening, set apart from that threshold plate ( 9 ) and the outflow opening; the shut-off body ( 11 ) being located in the shut-off position, viewed in a direction transversely to the longitudinal direction (L) of the conveyor screw ( 6 ), next to the threshold plate ( 9 ) and, in the transversal direction, being shaped in such a way that the shut-off body ( 11 ) and the threshold plate ( 9 ) together shut off the outflow opening of the outflow channel ( 7 ); and wherein the shut-off body ( 11 ) is shaped in such a way that the shut-off body ( 11 ) protrudes in the shut-off position, viewed from the downstream side of the threshold slate ( 9 ) in the upstream direction, along and past the threshold plate ( 9 ) on the upstream side of the threshold plate ( 9 ).
