Patent number: 7328548Abstract: A device comprising a plug positioned within a housing to regulate air within a container, for example, plastic storage containers or bags. The plug is positioned within the housing to occlude a port hole in the housing. The housing is positioned within a container so the port hole faces a wall of the container. A hole is created in the container above the port hole. To evacuate or inject air into the container, a hose adaptor with a specialized hose tip is connected to a vacuum or air hose. When inserted into the port hole, the hose tip temporarily displaces the plug from the port hole. Vents within the housing allow air to move through the housing and into or out of the hose tip. Removal of the hose tip allows the plug to resume position over the porthole to maintain the vacuum or air pressure within the container.Type: GrantFiled: September 12, 2005Date of Patent: February 12, 2008Inventor: Joseph M.

Patent number: 6952906Abstract: The present invention provides a chair having a removable outer cover. The chair has an air permeable bladder which houses compressible filler material. The compressible filler material allows the chair to be selectively compressed between various compressed states. A method for packaging the chair is provided which significantly reduces the weight and size of the chair. The method includes placing the chair in a vacuum chamber and suctioning air from the chair. The vacuum chamber may be partially open or closed during storage.Type: GrantFiled: September 15, 2003Date of Patent: October 11, 2005Assignee: Lovesac CorporationInventor: Shawn Nelson

Patent number: 6941727Abstract: A method and a system of transporting a commodity includes the step of placing the commodity in a flexible hermetic container. The commodity is stored in the flexible hermetic container for at least a specific time period. The commodity is then moved from the flexible hermetic container to a shipping container having an insect barrier liner. The commodity is transported in the shipping container. The specific time period is a sufficient time period to kill substantially all of the insects that have infested the commodity prior to placement in the flexible hermetic container. In one embodiment, a vacuum is drawn on the flexible hermetic container to reduce the specific time period and an optional small amount of pesticide can be injected into the flexible hermetic container to which a vacuum has been applied to further reduce the specific time period. An inert gas is used to reduce the specific time period.Type: GrantFiled: November 26, 2001Date of Patent: September 13, 2005Assignees: GrainPro, Inc., The State of Israel-Ministry of Agriculture & Rural DevelopmentInventors: Philippe Villers, Tom De Bruin, Shlomo Navarro

Patent number: 6918232Abstract: A package of a strip of material is formed by slitting or perforating a web to separate the web into side by side strips and fan folding the web to form a plurality of side by side stacks of the strips. The strip of each stack is spliced to the strip of the next stack to form a continuous strip through the package which can be unfolded for supply continuously to an end use machine. The package while compressed is wrapped by a packaging material which includes a bottom rigid plate, a top header and heat shrink bag wrapped around the package and under the bottom plate and heat sealed to a plastic layer covering a bottom surface of the bottom header plate.Type: GrantFiled: June 20, 2002Date of Patent: July 19, 2005Assignee: BKI Holdinfs CorporationInventors: Steve Sze Wan Lam, Alan Jeffrey Campbell, Randall Flaman

Patent number: 6901722Abstract: A multi-component bedding assembly, including a mattress or futon, is vacuum packaged in an air impermeable bag by drawing a vacuum at the open end of the bag and applying a ram or pushing force against the bedding assembly at the closed end of the bag. The pushing force may be intermittently cycled. The packaged bedding assembly also may be wrapped in a woven polyethylene overwrap and tied with bands before it is inserted into a shipping carton.Type: GrantFiled: September 25, 2003Date of Patent: June 7, 2005Assignee: Foamex L.P.Inventors: Paul N. Dextraze, Paul A. Haslanger

Patent number: 6889484Abstract: A method and apparatus for treating bagged materials. A bagging machine is equipped with feed tubes that feed a conduit through a bag filling tunnel of the machine and through the open end of the bag and into the bag. The conduit is perforated and when the bag is filled, the length of the conduits is extended out through the bag end to be connected to a treatment media, e.g., forced air. An opening is provided at the rear end to provide an exhaust opening for air that is forced into the conduit, out the perforations and through the bagged material. The air will dry the material to lower the moisture content or provide oxygen as may be desired to enhance decomposition. Water may also be introduced as desired.Type: GrantFiled: October 12, 1993Date of Patent: May 10, 2005Assignee: Miller-St. Nazianz, Inc.Inventors: Ronald V. Garvin, Larry R. Inman, Arthur P. Schuette

Patent number: 6880312Abstract: A process for delivering a cold or heat storage medium into a carrier material, in which the carrier material is located in a container which can be at least partially evacuated. The process includes the steps of: a) placing the carrier material in a container made of film material, b) at least partially evacuating the container made of film material, and c) delivering cold or heat storage medium to the at least partially evacuated container made of film material so as to saturate the carrier material with the cold or heat storage medium.Type: GrantFiled: July 18, 2003Date of Patent: April 19, 2005Assignee: Webasto Thermosysteme International GmbHInventors: Wolfgang Kraemer, Robert Lang, Kemal-Edip Yildirim

Patent number: 6862867Abstract: A system for sealing thermoplastic film includes one or more bag sealing units, each comprising a lower vacuum platen and a vacuum chamber cover adapted for sealing engagement on the platen to form a vacuum chamber. A sealing bar assembly includes a sealing bar designed for constant heated operation and a pair of cooling plates which function as heat sinks. The sealing bar assembly is pneumatically reciprocated between a raised, disengaged position and a lowered position with the sealing bar engaging the neck of a bag for hermetically sealing same. The cooling plates clamp the bag neck against a sealing support assembly. A method of sealing a thermoplastic film bag includes the steps of placing a packaging object in a thermoplastic bag and placing the bag on a cradle with the bag neck extending over a bag support assembly. A vacuum chamber cover is placed on the platen and evacuated to form a vacuum chamber. A sealing bar assembly melds the thermoplastic to form a sealed area across the bag neck.Type: GrantFiled: January 16, 2003Date of Patent: March 8, 2005Assignee: Pack-Tech, L.L.C.Inventors: Derril R.
