Abstract
Withdrawal apparatus or dispenser for the withdrawal of a flowable product from a container, the dispenser being positionable on an outlet plug of the container, and comprising a pipe-shaped withdrawal channel, which can be closed by a closure element. The closure is formed by a plate-shaped closure flap which is rotatable around an axis piercing the withdrawal channel and being arranged orthogonally thereto, the closure flap being sealed with respect to the withdrawal channel by a surrounding or ring-shaped elastic seal.

Apparatus for withdrawing a flowable product from a container having an outlet plug, the apparatus being positionable on the outlet plug connected to the container and being provided with a tube-shaped withdrawal channel which can be closed by a closure element, said apparatus comprising:
- a plate-shaped closure flap (5) to define the closure element, said flap being rotatable on an axis diametric to the withdrawal channel (8), said closure flap being sealed with respect to the withdrawal channel (8) by a surrounding elastic seal (45);
- and,
- a pipe-shaped knife shell (15) in said withdrawal channel, said shell having a knife edge (16) directed toward the outlet plug (2) and characterized in that a taper (42) is provided at the end facing toward the closure flap (5), which taper is formed in such a way that the closure flap (5) can be partially opened without moving the knife shell (15) toward a closure plate (17).
Apparatus for withdrawing a flowable product from a container having an outlet plug, the apparatus being positionable on the outlet plug connected to the container and being provided with a tube-shaped withdrawal channel which can be closed by a closure element, said apparatus comprising:
- a plate-shaped closure flap (5) to define the closure element, said flap being rotatable on an axis diametric to the withdrawal channel (8), stub axles (6a, 6b) extending from the closure flap (5) define the bearing of said closure flap (5), the rotational axis of the stub axles coinciding with a dividing slit (7) in the apparatus, said closure flap being sealed with respect to the withdrawal channel (8) by a surrounding elastic seal (45);
- and,
- a pipe-shaped knife shell (15) in said withdrawal channel, said shell having a knife edge (16) directed toward the outlet plug (2) and characterized in that a taper (42) is provided at the end facing toward the closure flap (5), which taper is formed in such a way that the closure flap (5) can be partially opened without moving the knife shell (15) toward a closure plate (17).
Apparatus for withdrawing a flowable product from a container having an outlet plug, the apparatus being positionable on the outlet plug connected to the container and being provided with a tube-shaped withdrawal channel which can be closed by a closure element, said apparatus comprising:
- a plate-shaped closure flap (5) to define the closure element, said flap being rotatable on an axis diametric to the withdrawal channel (8), stub axles (6a, 6b) extending from the closure flap (5) define the bearing of said closure flap (5), the rotational axis of the stub axles coinciding with a dividing slit (7) in the apparatus, said closure flap being sealed with respect to the withdrawal channel (8) by a surrounding elastic seal (45), the surrounding seal (45) is arranged in a surrounding recess (46) and is provided with openings for the stub axles (6a, 6b);
- and,
- a pipe-shaped knife shell (15) in said withdrawal channel, said shell having a knife edge (16) directed toward the outlet plug (2) and characterized in that a taper (42) is provided at the end facing toward the closure flap (5), which taper is formed in such a way that the closure flap (5) can be partially opened without moving the knife shell (15) toward a closure plate (17).
Apparatus for withdrawing a flowable product from a container having an outlet plug and a frangible sealing plate, the apparatus being positionable on the outlet plug connected to the container and being provided with a tube-shaped withdrawal channel which can be closed by a closure element, said apparatus comprising:
- a plate-shaped closure flap defining the closure element, said flap being rotatable on an axis diametric to the withdrawal channel, said closure flap being sealed with respect to the withdrawal channel by a surrounding elastic seal;
- and,
- a pipe-shaped knife shell in said withdrawal channel, said shell having a knife edge directed toward the outlet plug and characterized in that a space is provided at the end facing toward the closure flap (5) in such a way that the closure flap (5) can be partially opened without moving the knife shell (15) toward the frangible sealing plate (17).
