Patent number: 8763866Abstract: The compressed CO2 gas source is an insert that can be fixed in a sealed manner in an opening of the vessel. The insert has a high-pressure CO2 cartridge, a pressure-regulating valve for discharging CO2 therefrom and a rotary knob that is accessible from the outside. The rotary knob cooperates with an axially guided slide, which can be actuated to pierce the high-pressure CO2 cartridge with a piercing needle.Type: GrantFiled: May 27, 2006Date of Patent: July 1, 2014Assignee: Huber Packaging Group GmbHInventors: Kurt Oberhofer, Timm Oberhofer

Patent number: 8251257Abstract: The compressed CO2 gas source is an insert that can be fixed in a sealed manner in an opening of the vessel. The insert has a high-pressure CO2 cartridge, a pressure-regulating valve for discharging CO2 therefrom and a control element that is accessible from the outside and that can be actuated to pierce the high-pressure CO2 cartridge. The control element can be automatically interlocked and blocked against further actuation after it has first been actuated.Type: GrantFiled: May 27, 2006Date of Patent: August 28, 2012Assignee: Huber Packaging Group GmbHInventors: Kurt Oberhofer, Timm Oberhofer

Patent number: 7784651Abstract: A tap for removing liquid from a container has a sleeve (10) made of plastic, in which a piston (12) is guided, and which sleeve has a passage opening (28) for the liquid. A hood that can be set onto the sleeve (10) in front of the passage opening (28), so that it covers the passage opening (28), serves as a foam throttle. The hood encloses a labyrinth channel (36), together with the sleeve, which channel is open at one end, towards the interior of the container, and ends in the passage opening (28) at the other end.Type: GrantFiled: July 1, 2004Date of Patent: August 31, 2010Assignee: Huber Packaging Group GmbH + Co.

Publication number: 20100140265Abstract: The invention relates to a container that can be filled with fluid and closed pressure-tight and from which fluid can be removed, having an insert that can be fixed in an opening of the container while sealing the same. The insert has a high-pressure CO2 cartridge (14), a pressure regulating valve for dispensing CO2 therefrom, and an actuator accessible from outside, the actuation of which taps the high-pressure CO2 cartridge (14). An overpressure safeguard provides, upon undesired increases in pressure in the container, a flow path from the head space thereof through the insert to the atmosphere. The overpressure safeguard is designed as a burst safeguard. It bursts after an internal pressure is exceeded at which the container visibly crowns, but before reaching an internal pressure at which the container explodes.Type: ApplicationFiled: May 6, 2008Publication date: June 10, 2010Inventors: Kurt Oberhofer, Timm Oberhofer

Patent number: 7380683Abstract: The closure has a bung bushing (10) of elastic material which fits sealingly into the charging hole of the container. The bung bushing (10) has a central opening. A bung plug (18) is seated sealingly in the central opening. The bung plug (18) can be pushed out in the direction of the inside of the container. It is the valve member of a manually operable pressure-compensating valve.Type: GrantFiled: August 17, 2000Date of Patent: June 3, 2008Inventors: Kurt Oberhofer, Karl Batschied

Publication number: 20080057243Abstract: The invention relates to a container which has a sealed, external diffusion barrier layer which covers the whole surface and which is made of a film material, and a continuous supporting plastic layer which forms the top surface. The plastic layer does not require use of a plastic material having a superior barrier effect against oxygen and/or carbon dioxide diffusion.Type: ApplicationFiled: September 16, 2005Publication date: March 6, 2008Inventors: Kurt Oberhofer, Timm Oberhofer

Patent number: 6742682Abstract: The tap has a tap bushing (10) with a passage opening (34) for the liquid to be discharged. A piston (12) is guided so as to move axially within the tap bushing (10) and has an entry opening (36) and an exit opening (38) for the liquid. The piston (12) closes off the passage opening (34) in a locked position when it is moved in. The entry opening (36) of the piston (12) is in connection with the passage opening (34) in an extended position of the piston (12). A locking bushing (14) that is guided to rotate on the piston (12) is seated in the piston (12), which locking bushing (14) optionally closes off the exit opening (38) or brings it into connection with a passage opening (44) of the locking bushing (14).Type: GrantFiled: December 30, 2002Date of Patent: June 1, 2004Assignee: Oberhofer Werkzeugbau GmbHInventors: Karl Batschied, Kurt Oberhofer

Patent number: 6161716Abstract: The closure has a bung-type socket (10) of soft elastic material with a flange-like outer bearing portion (12), a circumferential sealing portion (16) sealingly receiving the rim of the hole, and a circumferential snap-action portion (18) engaging the inside of the rim of the hole from behind. In the sealing portion (16) and the snap-action portion (18) of the bung-type socket (10) there is embedded a coaxial reinforcing ring (20) of hard plastic, which is radially rippled over the circumference and thereby is covered by the soft-elastic material in thickness varying over the circumference. The bung-type socket (10) has a central orifice (24), in which a manually adjustable valve element (26) of the pressure-compensating valve occupies a sealing closed position and a pressure-compensating position.Type: GrantFiled: July 2, 1999Date of Patent: December 19, 2000Inventors: Kurt Oberhofer, Karl Batschied, Udo Schreiner

Patent number: 6065631Abstract: The closure has a bung-type socket (10) of elastic material which fits sealingly into the filling hole and is provided with a central orifice (18). The valve element (20) of the pressure-compensating valve occupies in the central orifice a clearly defined closed position and a clearly defined pressure-compensating position, between which it can be turned within limits defined by stops. The bung-type socket (10) has a lateral pressure-compensating duct (42), the outside end of which is disposed above the liquid level in the completely filled container. The valve element (20) in pressure-compensating position opens up a flow path from the inside end of the pressure-compensating duct (42) to the upper side of the bung-type socket (10), while in closed position it shuts off the path on the inside, covers it on the outside and seals it tightly on both inside and outside.Type: GrantFiled: July 2, 1999Date of Patent: May 23, 2000Inventors: Kurt Oberhofer, Karl Batschied, Udo Schreiner
