Filling and emptying provisions for two-component spray cans

The innovation "relates to the filling and draining devices for two-component spray cans "or spray cans, in particular for spraying foams, with one can containing the synthetic resin or the like, while in another Can contain the hardening agent and propellant gas, which mixture ingredients are put into the can immediately before use be transferred with the synthetic resin or the like.

It is known to spray hard or soft foams from spray cans after those contained in two separate cans Components are combined in one of the two boxes using so-called "parent and parent valves" specially developed for this purpose have been.

The Kc ^ erunr; The object is to simplify storage of the valves for the two doses of a Zv v; earth.

According to the innovation, this object is primarily achieved in that both cans have a transfer valve xxnä that the valve of the can containing the synthetic resin or the like is provided with a riser. 5 ¹ For decanting, an intermediate nipple with an axial hole is provided, into which the nozzles of the valves of both cans are to be inserted.

For the valve of both components and after decanting the can containing the propellant gas is provided with a spray head, which is to be put on after decanting.

The axial bore of the intermediate nipple expediently has eir middle section with reduced diameter.

The! Inflation is now based on them for example reproducing drawing described, namely shows

The new un-rsrem'iße 'ifcfilling and emptying device is using the example of a Zv; eikomponenten 3prajdosensai; zes for spraying described by foam; however, it can also be used in other pills, including components and us

Fit · 1 of the drawing shows sv; ei spray cans A and B. of which the can A contains a precisely matched amount of synthetic resin or del. Without pressure or propellant gas, while the corresponding hardener 1 and the propellant gas are in the can B. The cans A and B are shown in the transfer position and have the same transfer valves 2 and 3, the structure of which is known and in. individual should not be described here. The only difference between the two valves 2 and 3 is that the valve 2 of the can A is provided on the inside with a riser tube M- .

An intermediate nipple 5 ax of an axial bore is used for decanting 6 is provided, which has a middle section 7 of reduced Has diameter and in outer sections 8, the spouts 9 of the valves 2 and 3 receives .. By pressing the both cans A and B in the position shown in the drawing the contents of can B (hardener and propellant gas) into the Can A was transferred to the synthetic resin or the like. Then the socket B and the intermediate nipple ρ τοη of the socket A are removed .. Bie Can A is shaken, whereby the substances brought together react.

To empty the contents of the can A (see SchsuEkunststoff) a spray head 10 (5 ¹ Ig- 2) is now placed on the sand 11 of the can A, a central socket 12 of the spray head 10 being connected to the nozzle 9 of the Yentil 2 brought = jird. The valve 2 is opened by pressing a finger plate 15, and the reacting Hasse (foam in the present application example) emerges from a nozzle 14 of the spray head 10.

The "fire" also applies to amendments to the "enclosed" Schxitz claims 1 outlined execution form and provides for sxciL but also, to all the HeuerungsmersHale, which in one -

or in combination - in the entire description and drawing are disclosed.
