- a method for charging a dry ice drinking vessel with dry ice comprising:
- the Invention can comprise an apparatus and method for loading dry ice into a perforated dry ice chamber defined by a dry ice drinking vessel.
- the dry ice drinking vessel has an interior communicating with the dry ice chamber by at least a primary and a secondary perforation.
- liquid carbon dioxide is allowed to expand from the liquid to the gaseous phase and is simultaneously introduced into the dry ice chamber of the dry ice drinking vessel.
- the liquid carbon dioxide flashes into gas because of the sudden drop in pressure.
- the sudden change is state of the carbon dioxide causes a sudden drop in temperature of the carbon dioxide and causes a portion of the carbon dioxide gas to freeze into dry ice.
- the dry ice is trapped in the dry ice chamber by a filter, charging the dry ice chamber of the drinking vessel.

- the interior defines an interior longitudinal axis and the body defines a body longitudinal axis.
- the interior and the body longitudinal axes are coincident when the body and interior are in engagement.
- the orifice appears on the body longitudinal axis at a free end of the body and the primary perforation appears at a corresponding location on the interior longitudinal axis, which provides for the alignment of the orifice and primary perforation.
- the filter and the opening in the body may be annularly arranged about the orifice on the cylindrical body.
- the one or more secondary perforations are arranged to align with the opening and the filter when the body and interior are in engagement.
- the body holds the filter in position against the secondary perforations when the body and interior are in engagement.
- the body may be hollow.
- the shape of the body corresponds to the shape of the drinking vessel. If the drinking vessel interior is cylindrical, the body also will be cylindrical.
- the filter may be attached to the free end of the body and the periphery of the filter is bonded to and supported by the free end of the body.
- the filter may be circular to conform to the cylindrical interior of the dry ice drinking vessel.
- the filter is selected to allow the passage of carbon dioxide gas in the quantities that are discharged by the apparatus while preventing escape of dry ice powder.
- the cylindrical body and the circular filter engage the inside surface of the interior of the drinking vessel when the body is placed into engagement with the drinking vessel.
- the cylindrical body holds the circular filter in place against the secondary perforations of the chamber, thus filtering the carbon dioxide powder from the escaping carbon dioxide gas and air, when the apparatus is engaged with a drinking vessel and liquid carbon dioxide is being discharged into the chamber.
- the filter also serves to restrict bypassing of the primary perforation by dry ice flowing from the orifice.
- the drinking vessel is placed in engagement with the body, with the body engaging the interior of the drinking vessel, the orifice is aligned with the primary perforation and the filter is in engagement with the secondary perforations.
- the valve is opened and liquid carbon dioxide is injected into the chamber.
- the liquid carbon dioxide flashes into carbon dioxide gas upstream of the orifice. Expelled air and carbon dioxide gas pass through the secondary perforations of the chamber and through the filter. Frozen carbon dioxide powder is filtered from the gas stream by the filter and is retained in the dry ice chamber.
- the chamber contains an adequate amount of carbon dioxide powder, the flow of liquid carbon dioxide gas is stopped and the drinking vessel removed from the apparatus.
- a beverage is dispensed into the drinking vessel and a portion of the beverage freezes into a composite solid with the carbon dioxide powder.
- the carbon dioxide in the resulting dry ice/beverage composite then sublimates, causing a boiling, smoking effect of the beverage.
- the creation of the dry ice/beverage composite has the benefit of extending the visual effect compared with charging the dry ice drinking vessel with dry ice pellets because the dry ice in the composite sublimates slower than the dry ice alone.
- the creation of the dry ice using liquid carbon dioxide to create the dry ice also is a benefit because the liquid carbon dioxide may be easily transported and stored indefinitely at room temperature, unlike dry ice pellets.
- the apparatus may include a pressure relief valve to prevent application of excessive pressure to the apparatus.
- the apparatus may include a fixture to hold the drinking vessel in the correct position when the drinking vessel is being charged with dry ice.
- the fixture may comprise a dry ice charging station having a base containing the pressure vessel and the valve.
- the dry ice charging station may include a dry ice drinking vessel containment to enclose the dry ice drinking vessel during charging.
- the apparatus may include an electrically operated valve to control the flow of liquid carbon dioxide.
- the invention is an apparatus and method for charging a dry ice drinking vessel with dry ice.

- d. collecting dry ice formed within said dry ice chamber from the received carbon dioxide, and releasing gas from said dry ice chamber through said secondary perforation and said filter; and
- e. removing said interior of the dry ice drinking vessel from engagement with said body.
- It should be appreciated that the Invention can comprise an apparatus and method for loading dry ice into a perforated dry ice chamber defined by a dry ice drinking vessel. The dry ice drinking vessel has an interior communicating with the dry ice chamber by at least a primary and a secondary perforation. To load solid dry ice into the dry ice chamber, liquid carbon dioxide is allowed to expand from the liquid to the gaseous phase and is simultaneously introduced into the dry ice chamber of the dry ice drinking vessel. The liquid carbon dioxide flashes into gas because of the sudden drop in pressure. The sudden change is state of the carbon dioxide causes a sudden drop in temperature of the carbon dioxide and causes a portion of the carbon dioxide gas to freeze into dry ice. The dry ice is trapped in the dry ice chamber by a filter, charging the dry ice chamber of the drinking vessel.
- The carbon dioxide is maintained in liquid form under high pressure at room temperature in a pressure vessel. A valve and piping controls the flow of the liquid carbon dioxide from the pressure vessel. The apparatus has a body that is configured to selectably engage the interior of the dry ice drinking vessel. The body includes an orifice. The orifice is plumbed to receive carbon dioxide from the pressure vessel by way of the valve. When the interior of the dry ice drinking vessel is placed in engagement with the body, the orifice is aligned with a central perforation of the chamber. The carbon dioxide is propelled from the orifice through the primary perforation and into the dry ice chamber when the valve is opened.
- The liquid carbon dioxide from the pressure vessel may flash into carbon dioxide gas and then into dry ice upon exiting the orifice. Alternatively, the change of state may begin upstream of the orifice at an expansion valve located within the system piping.
- The frozen dry ice takes the form of a powder. Air in the dry ice chamber and the portion of the gaseous carbon dioxide that does not freeze are expelled by the pressure of the incoming carbon dioxide from the dry ice chamber through one or more secondary perforations. An opening in the body is aligned with the one or more secondary perforations when the interior of the dry ice drinking vessel is in engagement with the body. The frozen carbon dioxide is prevented from being expelled from the chamber by a filter. The filter is mounted to the body and is interposed between the one or more secondary perforations and the opening defined by the body. The portion of the carbon dioxide gas that does not freeze passes through the filter, while the filter substantially prevents the dry ice powder from exiting through the secondary perforations in the dry ice chamber.
- The interior of the dry ice drinking vessel and the body may be placed in selectable engagement. The interior defines an interior longitudinal axis and the body defines a body longitudinal axis. The interior and the body longitudinal axes are coincident when the body and interior are in engagement. The orifice appears on the body longitudinal axis at a free end of the body and the primary perforation appears at a corresponding location on the interior longitudinal axis, which provides for the alignment of the orifice and primary perforation.
- The filter and the opening in the body may be annularly arranged about the orifice on the cylindrical body. The one or more secondary perforations are arranged to align with the opening and the filter when the body and interior are in engagement. The body holds the filter in position against the secondary perforations when the body and interior are in engagement.
- The body may be hollow. The shape of the body corresponds to the shape of the drinking vessel. If the drinking vessel interior is cylindrical, the body also will be cylindrical. The filter may be attached to the free end of the body and the periphery of the filter is bonded to and supported by the free end of the body. The filter may be circular to conform to the cylindrical interior of the dry ice drinking vessel. The filter is selected to allow the passage of carbon dioxide gas in the quantities that are discharged by the apparatus while preventing escape of dry ice powder.
- The cylindrical body and the circular filter engage the inside surface of the interior of the drinking vessel when the body is placed into engagement with the drinking vessel. The cylindrical body holds the circular filter in place against the secondary perforations of the chamber, thus filtering the carbon dioxide powder from the escaping carbon dioxide gas and air, when the apparatus is engaged with a drinking vessel and liquid carbon dioxide is being discharged into the chamber. The filter also serves to restrict bypassing of the primary perforation by dry ice flowing from the orifice.
- In use, the drinking vessel is placed in engagement with the body, with the body engaging the interior of the drinking vessel, the orifice is aligned with the primary perforation and the filter is in engagement with the secondary perforations. The valve is opened and liquid carbon dioxide is injected into the chamber. Alternatively, the liquid carbon dioxide flashes into carbon dioxide gas upstream of the orifice. Expelled air and carbon dioxide gas pass through the secondary perforations of the chamber and through the filter. Frozen carbon dioxide powder is filtered from the gas stream by the filter and is retained in the dry ice chamber. When the chamber contains an adequate amount of carbon dioxide powder, the flow of liquid carbon dioxide gas is stopped and the drinking vessel removed from the apparatus.
- A beverage is dispensed into the drinking vessel and a portion of the beverage freezes into a composite solid with the carbon dioxide powder. The carbon dioxide in the resulting dry ice/beverage composite then sublimates, causing a boiling, smoking effect of the beverage. The creation of the dry ice/beverage composite has the benefit of extending the visual effect compared with charging the dry ice drinking vessel with dry ice pellets because the dry ice in the composite sublimates slower than the dry ice alone. The creation of the dry ice using liquid carbon dioxide to create the dry ice also is a benefit because the liquid carbon dioxide may be easily transported and stored indefinitely at room temperature, unlike dry ice pellets.
- The apparatus may include a pressure relief valve to prevent application of excessive pressure to the apparatus. The apparatus may include a fixture to hold the drinking vessel in the correct position when the drinking vessel is being charged with dry ice. The fixture may comprise a dry ice charging station having a base containing the pressure vessel and the valve. The dry ice charging station may include a dry ice drinking vessel containment to enclose the dry ice drinking vessel during charging. The apparatus may include an electrically operated valve to control the flow of liquid carbon dioxide.
