Falsskopf with device for simultaneous! Filling and dosing of the propellant gas for

Aerosol cans

The subject of the invention is a head which is suitable to be used in propellant gas metering devices, wherein This head is especially suitable for making the seam connection of the valve with the can containing the liquid. is suitable and is also capable of doing the simultaneous Carry out filling and metering of the propellant gas.

It i & t known that it is presently used to manufacture the full-

constant filling of an aerosol can is necessary to first fill the can with the liquid to be distributed, then the can using a so-called folding machine »which the Flanging a collar of said valve around the Neck of the can itself makes * rait to connect the valve " During subsequent handling, the thus perfected can is placed under a filling and dosing device of the propellant gas brought over there; valve itself that Introduces propellant gas into the can at the required pressure »

The purpose of the present invention is to provide a head au realize, even with pre-existing machines can be applied and the fa ^ gates and the simultaneous Filling and metering of the propellant gas with a single handling vorirssrät, with both the to one of the two operations, folding or filling, as well as the time required to transfer from one to the other Machine can be saved according to the old method of necessary lost time *

The charging head according to the invention is simple and strong. ensures perfect operation and is suitable to do this, all the operations described above are carried out automatically to execute.

The invention is essentially characterized in that expansion clamps are provided coaxially opposite an adjusting ring of the valve and the can to be folded and filled, the lowering and the spraying apart of said expansion clamps being controllable by an adjusting ring on "the can itself, via the Ring of the inlet of a valve for the pressure fluid is to be opened, which by means of a piston adjusts a wedge for spreading the expansion clamps apart and further connecting means are provided between the gas inlet or the filling fluid with the can, the filling by means of light worlds and closable cross-sections , which are cover in predetermined.., positions of the expansion clamp, the can * valve spindle opposite, takes place »

The following for a better understanding of the invention detailed description,., which are merely illustrative » so is not restrictive and is based on conditional drawing, which is an axial section through an inventive Füll · »and the hemming head shows, refers to«

As the figure shows, the generally designated 1 comprises Head one of two connected to one another by means of bolts 4 Parts £ and> existing body.

With this head there are two entrances connected, one of which generally denoted by 5, for the propellant gas intended for filling the can, the propellant gas being indicated by the arrow <£ Takes barrel and comes from a dosing device of known design not illustrated in the drawing, and a second entry, generally designated 6 for the compressed air, the one indicated by the arrow A is intended interpreted run takes place *.

A ring 7 is connected to part 2 of the head 1 like a telestop * which in part 3 can be limited by the width of the slot 3 which cooperates with a pin 9 screwed onto part 2. *. - *

At these 1st ring 7, a second, for example, by screwed ν adjustable ring Io vbefestigt, a seat 11 2UR [receiving the upper VenfcHtöils, for connection to a j under the part 11 and not arranged in the drawing veran *. ; has real flashes. Jr

The position of the ring Io is opposite that of the Hinges 7 Screw connection and subsequent locking in the mutual Position in the middle of a counter nut 12 and a locking screw l> adjustable «you move the ring Io and

that of the ring 7 is caused by the action of a spring 14 influenced. At one end part of the ring 7 is a coupling provided with a pull rod 15 * di © after passing through an associated opening in the body 3 to a 'control button 16 of a valve 17 leads, the parts such are arranged that as soon as by means of the pull rod 15 against the spring 18, the shut-off valve 17 is adjusted becomes / the clear multiple to the passage of the from A in direction the arrow of the coming air remains open.

The body 2 of the head 1 opposite can in a 19 designated cavity slide a piston 2o, the tightness of which is guaranteed by a seal 21 *

This piston moves in opposition to a spring 22 and as soon as the piston lowers, he takes a WelliHnit, whereby the seal to the outside and especially for a · » If the propellant gas occurs through the seals 24, 25 and 26 is guaranteed. Inside is the wave 2> hollow and has an axial cavity 27 * the one with the inlet of the gas Q is in communication and opens into a wide cavity 28 in which a piston 29 is located.

The connection between the chamber 28 and the piston 29 is loosely, and the gas can in the cavity between the piston 29 and around the wall of the chamber fiS »

The body j5 opposite axially fixed However clamps Jo are provided this against radial swinging "the inclined at their end surfaces $ 1 have, so that, 'when the Kell integral with the axis of the shaft SJ is lowered J52, the clamps 30 radially be pushed outside ·.

A connecting head J3 can slide inside the wedge 32 and is firmly connected to the piston 29, which is held in the illustrated position by the action of a spring 24.

This piston carries at its end part a seal 25 which So formed is "that it represents a cavity" in the the shaft of the aerosol can to be filled click into place in a sealed manner can. The way of working is as follows:

The can to be filled with a superimposed but not yet attached valve is placed under the head, coaxially with the seat il, when the head I is lowered or when the filler is raised. Can this comes into contact with the slide 11 and the ring io is then raised against the spring 14 until the king f hits part 57 *, which acts as a stop.
