Distribution devices for powder with one valve operated by a pusher

The present invention relates to distribution devices for powder with a valve operated by a pusher. The invention particularly relates to lightweight hand-held distribution devices such as those under the cover Known aerosol bombs. Devices correspond.

For the atomization of liquids in the form of solutions » Emulsions or flowable pastes are also used ■ Aiaten aerosol tubes are used. With these devices

let also the atomization of those in suspension fine powders possible, however the concentration may not exceed the * 8 powder in its liquid medium 15 # do not pour over it, as the stability of the Suspension is at risk and there is a risk that Verr clogging of the valve lines can occur.

With regard to the atomization of powders, attempts have been made to use aeroeol bombs of the classic type, the Contain only a single container in which the liquefied gas and the active product to be distributed are rented. These attempts were not entirely satisfactory, however, since the powder settles on the bottom of the container and consequently the atomization product essentially alone from the Propellant gas exists when the bomb is through the valve Pressing the push button opens. In this way, the hoped-for hail-like discharge of a powder cloud is not achieved obtain. . _ _ ■ - ·

In order to avoid these disadvantages, the applicant has already made the proposal to use a special type of aerosol distribution devices for the discharge of powders, which on the one hand comprise two containers, one of which is the liquefied gas serving as a propellant and the other the one to be atomized Receives powder, and which on the other hand have a push-button operated ejector. The propellant sucks the powder in at the moment of ejection due to the Venturi effect. In this case the difficulties regarding the stability of the powder in suspension and the compatibility of the latter with the propellant are eliminated, but there is still the risk of the valve being blocked by the powder. In addition, certain other disadvantages also arise, which are explained below. .

909843/027 $

The suction of the powder through the Venturi effect leads to a waste of propellant gas due to the Venturl effect the amount of gas sucked in that is supposed to entrain the powder, only a small rope, for example 1/100 or less, which represents the initial diameter of the propellant gas.

It has also been found that the powders tend to to agglomerate and the generally! narrow and narrow Pre-plug lines in which they are sucked in at a relatively low speed of a few centimeters per second. It has also been found that after suction a certain powder ner-ge the remaining in the container Powder has a tendency to form a kind of vault over the surface Has suction opening, such that the powder kei to the opening has more access.

Se are already known gate poles which improve the operation of Aercsol distribution devices of the above type in which the powder is displaced by the propellant gas instead of being sucked into it. In this embodiment, the propellant gas emerging from its container when the valve is opened is directed to the bottom of the powder container. This gas flow under pressure is intended to traverse practically the entire powder column and to create turbulence for practically the entire powder column and exit into the upper part of the powder container, dragging the powder emulsified as it passes through with it, which is distributed outward in the form of a cloud The 36 device has the disadvantage that it only works acceptably with powder volume below 0.3 liters. Moreover, finally, the condition occurs in certain clogging powders a, that the gas stream moves in ä.en same channels which he in

- 3 609843/0275

The stored powder has formed, and it no longer causes it to be entrained, due to the fact that the mixture of gas and powder released to the outside has a very fluctuating composition, is a further disadvantage.

In order to achieve better results, it has also already been proposed to use a pipe for the supply of the propellant and for the removal of the mixture of propellant and powder which is generally U-shaped and which is so disposed in the powder container is that it goes with the curved part of its U-part in near the bottom of this container. In this bent section of the tube two openings are provided in the cage of the container bottom wall, both of which are in such a way roughly to the powder mass above this part of the tube are directed that the perpendicular to these openings Central axes and the Rohrlüngsaohse at a certain distance cut above the bent part of the pipe. aside from that A fold is provided in the U-tube as well as the two openings. A major part occurs in this known arrangement of the propellant through the upstream opening, i.e. through the opening on the entry side of the propellant, a certain amount of powder being fluidized in the vicinity of this opening, and the resulting mixture of powder and propellant enters through the second, downstream opening on the other side of the fold the tube and is ejected from the top of the distribution device through the outlet leg of the U-tube.

Tests carried out with such a device have shown that a strong tendency to arch formation and / or sur clogging of the downstream opening in the Tube through which the powder is made. Even if the device works smoothly, the ratio of powder to Propellant at best only about 1: 1.
