BetMtxgungsknopf with automatic interruption of the outflow of pressurized liquids.

Numerous devices are known that automatically stop or interrupt the outflow of aerosolized or non-aerosolized liquid substances under pressure as soon as the button is manually interrupted »

The known devices have the disadvantage of being entangled and thus expensive. On the other hand, their mode of operation is not always satisfactory, especially with very dense liquid substances.

Another purpose of the invention is to develop an automatic locking actuator button into one low price, attachable to aerosol nozzles at any time and therefore generally usable.

The invention also aims to provide an actuating button that can be used for aerosolized or flexible substances Container can be used, which is the pressure of a propellant gas or are subjected to pressure exerted by hand.

The invention aims essentially to avoid the disadvantages mentioned or to achieve the above purpose and suggests an actuation button with automatic interruption; of the outflow of the pressurized liquid Substances that may or may not be aerosolized, which is detachably attached to the valve stem, thereby characterized in that it consists of an elastic hollow part which sealingly closes the outflow channel of the distributor nozzle can when the valve is in the closed position, and under the Pressure of the substance to be distributed is deformable by expansion in such a way that the aerosolized or not aerosolized Substance can flow out when the distributor nozzle is open.

In the drawing are some exemplary embodiments of the invention shown schematically with further details according to the invention

Fig. 1 is a section of the actuator button end, geiaäss one first embodiment of the invention;

FIG. 2 shows an illustration according to FIG. 1 of a first variant j

3, FIG. 3 shows a representation according to FIG. 1 of a second variant

FIG. 5 shows a representation, partly in section, of an aerosol valve stem which is provided with an actuating button according to FIG. 1 or 2 or 3;

Figures 4 and 6 are schematic representations from which it can be seen how the actuating button with a tilt valve cooperates or an inclined arrangement of the button with respect to the valve stem axis is possible.

Identical parts or with similar functions are given the same or similar reference symbols in the description below designated.

In FIGS. 1, 2, 3 _{and 5 f} , the left part represents the rest position with respect to the axis, and the right part represents the working position or the position when the actuating button is actuated and the valve stem is in the corresponding open position.

With UG the end (vertßilerdüse) of the actuating button EA is designated, which is provided with radial boring rings AE for the outflow, which were formed by compression molding, these radial bores extending from an axial channel CA of the actuating button. According to the invention, a plug-shaped component GI made of elastically deformable material is provided, which is provided with a central opening FI, which in the rest position (Fig. 1) exerts a lateral pressure on the full end part SP of the actuating button in such a way that a tight seal is achieved in this position . In the embodiment according to FIG. 1, the elastic key part 61 provided with an opening FI is designed like a plug and with an inner one

Rib SA provided with; a complementary groove SO des Actuation button engages; to do this with the Actuator button to stay firmly connected

The mode of operation is as follows:

As soon as the actuating button is pressed, the pressurized substance can flow out, whereby the same flows out of the bores AE and the elastic wall of the plug is deformed in such a way that a distribution of the substance over the outlet opening FI of the cap GI is obviously caused «As soon as the pressure of the conditioned en StojPfes ceases _t eg by closing the (known per se) the valve stem, the darning is automatically returned by elastic return action in the locking position, thus preventing the product discharge (see liken part of the figure 1).

The design according to FIG. 2 differs from that of FIG. 1 by a different nipple profile, this profile being that of the full mushroom-shaped button end SP is complementary, as well as by a frustoconical shape trained rib SA ', which on the one hand facilitates egg construction, and on the other hand prevents the stopper removal.

The embodiment according to Fig. 3 differs from that of Figs. 1 and 2 in that the elastic cap consists of a small washer DS, which is provided with the outflow opening FI and next to its opening FI sealing with a full axial end SP * of the button works together. A stiff clamp PR fixes the edge of the disk DS and is rigidly coupled to the mentioned end UG of the actuation button.

The mode of operation is basically the same as in FIG. 1.

It should be noted that the beta release button (Fig. 5) is formed with a flange FL, which like an end stop against the border capsule CU of the body CR (see Arrow Fl) of the actuating button cooperates in order to close the opening of the valve stem of the valve VA at the end. enable.

Fig. 6 shows an inclined arrangement of the operation button j Fig. 4 is an illustration of the valve W in a tilting design (which is already known per se).

As can be seen from the above, the invention is applicable to all valve stems of known construction.
