apparatus for isning, frostning or imning of ihaliga bodies, in particular glass

摘要

Apparatus for icing, freezing or frosting containers such as drinking glasses comprising a tank containing liquefied gas under pressure which is supplied through a valve and a coiled capillary conduit to a nozzle which sprays the liquefied gas into the interior of the drinking glass. A displaceable receiver plate is adapted for placement of the glass thereon and, in response to pressure applied to the glass, the receiver plate is displaced to open the valve which releases the liquefied gas from the tank into the coiled capillary conduit and, then, from the nozzle into the interior of the glass. The coil configuration of the capillary conduit provides resilience thereof and allows the same to undergo deformation as the receiver plate is displaced. The capillary conduit also serves to convey the liquefied gas along an elongated path to provide heat exchange with the ambient atmosphere, pressure reduction of the liquefied gas and a time lag so that, at discharge from the nozzle the liquefied gas is in an ideal liquid-gaseous state.
