US Patent:

7312253, Dec 25, 2007
Filed:

Dec 17, 2004
Appl. No.:

11/016312
Inventors:

Yash Paul Handa - Pittsford NY, US
Joseph A. Brackman - North Benton OH, US
Glenn C. Castner - Victor NY, US
Mohammad Zafar - Pittsford NY, US
Assignee:

Pactiv Corporation - Lake Forest IL
International Classification:

C08J 9/00
US Classification:

521 79, 521 98, 521142, 521146
Abstract:

A blowing agent blend for making thermoplastic polymer foams comprises methyl formate. The blowing agent blend can further comprise at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent (e. g. an inorganic agent, a hydrocarbon, a halogenated hydrocarbon, a hydrocarbon with polar, functional group(s), water or any combination thereof), or a chemical co-blowing agent, or combinations thereof. The thermoplastic polymer foam can be an alkenyl aromatic polymer foam, e. g. a polystyrene foam. The blowing agent blend can comprise any combination of methyl formate and one or more co-blowing agents. The methyl formate-based blowing agent blends produce stable foams for various applications, including containers, packaging systems, as well as insulation boards and building materials. A process for the preparation of such foams is also provided.

US Patent:

20060052465, Mar 9, 2006
Filed:

May 3, 2005
Appl. No.:

11/122158
Inventors:

Yash Handa - Pittsford NY, US
Glenn Castner - Victor NY, US
Mohammad Zafar - Pitsford NY, US
International Classification:

C08J 9/00
US Classification:

521079000
Abstract:

A blowing agent blend for making thermoplastic polymer foams comprises methyl formate. The blowing agent blend can further comprise at least one co-blowing agent, preferably an environmentally friendly chemical species (e.g., non-VOC and/or non-HAP). The co-blowing agent is either a physical co-blowing agent (e.g. an inorganic agent, a hydrocarbon, a halogenated hydrocarbon, a hydrocarbon with polar, functional group(s), water or any combination thereof), or a chemical co-blowing agent, or combinations thereof. The blowing agent blend can comprise any combination of methyl formate and one or more co-blowing agents, wherein the preferred co-blowing agent is 1-chloro-1, 1-difluroethane (HCFC-142b). The thermoplastic polymer foam can be an alkenyl aromatic polymer foam, e.g. a polystyrene foam. The methyl formate-based blowing agent blends produce stable foams for various applications, including containers, packaging systems, as well as insulation boards and building materials. A process for the preparation of such foams is also provided.

Filed:

Dec 17, 1999
Appl. No.:

9/466618
Inventors:

Daniel G. Carr - Rochester NY
Glenn C. Castner - Victor NY
Gary R. DelDuca - Canandaigua NY
Rollie H. DeMay - Newark NY

Assignee:

Pactiv Corporation - Lake Forest IL
International Classification:

A23B 400
US Classification:

426124
Abstract:

A modified atmosphere package includes first and second compartments separated by a partition member that is substantially permeable to oxygen. The first compartment contains an oxygen scavenger activated with an oxygen scavenger accelerator. The second compartment contains a retail cut of raw meat. Various techniques are employed to rapidly reduce the oxygen level in the second compartment below pigment sensitive levels so that the growth of metmyoglobin is inhibited. Some of these techniques increase the flow of oxygen from the second compartment to the first compartment through the partition member, while other techniques directly absorb oxygen within the second compartment by locating a second oxygen scavenger within the second compartment.

Hinged Lid Latching Mechanism
view source
US Patent:

55957692, Jan 21, 1997
Filed:

Jun 7, 1995
Appl. No.:

8/471879
Inventors:

Glenn C. Castner - Victor NY
Keith A. Messinger - Canandaigua NY
Donald E. Rowe - Newark NY
Assignee:

Tenneco Packaging - Evanston IL
International Classification:

B29C 5132
US Classification:

425183
Abstract:

The invention relates to a mold apparatus and a process for forming a lid latching mechanism in a thermoplastic container. The lid latching mechanism features a large, trapezoidally-shaped opening hole. The trapezoidal shape has been found to reduce the amount of tearing that can occur along the edges of an opening formed during the thermoforming process. The opening is created by the engagement between a fixed shear key mounted in a first mold member and a movable shear key which has a trapezoidally-shaped cutting surface and is mounted in a second mold member. The movable key travels along an inclined path as the mold members close on a preheated thermoplastic sheet to form a container.
