Abstract
A device for minimizing the blowback of carbon dioxide snow. Device includes a relatively planar body that includes an aperture for receiving a discharge horn. The discharge horn capable of being connected to a source of carbon dioxide and has an open bottom end for discharging solid carbon dioxide snow through the planar body into a container. The planar body further covering and opening to the container that is to receive the solid carbon dioxide snow with the planar body preventing blowback of solid carbon dioxide snow received into the container from exiting the container. In other words, the planar body acts as a shield against blowback of carbon dioxide snow as device is depositing same in the container.
