"Rotatable outlet cap"

The invention relates to an axially movable outlet closure for containers, in particular for Shut-off piston that contours the inner container are adapted and in the axial movement - during opening and closing - the deposited Substances are removed from the sealing piston by simultaneous radial movement »

Outlet closures with axially movable pistons are known. There are also sealing pistons known, which are adapted to the inner contours of the container to be closed "

These outlets are usually at the deepest Place on the bottom of the container so that the container can be completely emptied.

The remaining emptying of the container, especially in the case of the mixing container with a lower drive, is conditional the side installation of the spout at a certain angle of inclination on the container bottom. Inevitably, the shape of the piston must be used in the design of the aerodynamically favorable mixing container inner container contour can be adjusted, which creates a deposit option after the end of the mixing movement, especially with dry, powdery substances on the sealing piston. If after opening the If the sealing piston is completely emptied, the deposits on the piston will still be reclaimed in the emptied container ",

This can easily result in incorrect mixes or uselessness of the following batches »

It is therefore the task of this type of sealing piston during the opening movement also to be freed from residues. To solve the invention, it is proposed that the sealing piston during the axial movement to initiate a radial movement of at least 90 ° when opening, so that the deposits can be thrown off on the contours of the sealing piston «

For example, the invention is based on the Drawings are explained in more detail. These show in

Figure 2 = the open position of the lock piston.

The closure piston Λ is adapted to the shape of the container 2 in a flow-favorable manner and closes the container opening to the outlet housing 3.

The closing piston 1 is via a piston rod 4 · verbusden with a piston 5 * Through the alternating compressed air supply 6 and 6 ^ can the piston 5 in the air cylinder 7 moves back and forth be, whereby the Yerschlußkolben 1 the container opening closes or releases. According to the Yerschlußkolben 1 is during the axial Movement also moved radially by mimdestems 90 ° For example, a square guide 8 can cause the radial movement, which at the end of the hollow Piston position 4 is firmly attached «.

The square guide 8 slides during the
axial movement by means of an arbitrarily twisted animal velvet rod 9 which is fixedly arranged in the cylinder.
The locking piston 1 is thereby pivoted radially during the axial movement in accordance with the twisting of the profile rod 9 *

It is useful to seal the piston 1 first
from the closed position in a straight line and only initiate the radial movement when the piston 1 in the outlet housing 3 is free
This can be achieved, for example, by a straight! Guide 10 of the front part of the square bar 9 »

In the figure 2 the open position of the locking piston 1 is shown »The locking piston
1 has rotated in about 90 during the opening movement, with the deposits 11, possibly

with the support of eimee airflow 12 from the? spool piston 1 can be removed.

During the closing movement, the locking piston Λ is automatically rotated back into the starting position according to Figure Λ .
