Patent number: 7922021Abstract: A closure for a container comprises a base and a top cover. The base comprises a flange trap, a seal lock, and an opening. The top cover comprises a seal boss, a seal lock, a flange boss, and a top surface. The flange trap and flange boss secure the closure to a container when the closure is in a closed position. The seal locks are positioned to engage one another when the closure is in the closed position. The seal boss extends into the container when the closure is in the closed position to help prevent sauce or other liquid from leaking out of the container. A method for using a closure for a container and a container combination provides a closure and a container and arranges the closure so that the container is within the opening of the closure.Type: GrantFiled: May 6, 2004Date of Patent: April 12, 2011Assignee: Pactiv CorporationInventor: Craig A.

Patent number: 7913870Abstract: An improvement to a container of the type that includes a vacuum formed transparent base and lid, the container having opposite sides that each forms a base flap (20) and a lid flap (22) that lie adjacent and parallel to each other, wherein the container indicates if it has been opened after a store clerk has loaded food into the container. An indicator sheet (34) lies between the base and lid and has cut-out characters (60) lying in holes (62) of a carrier (64), the carrier being bonded to the base flap and the characters being bonded to the lid flap. The container is opened by a person pulling up the lid flap, with the characters lifting out of their holes as they move up with the lid flap, and with the carrier that forms the character holes remaining on the base flap. When the lid is closed by pressing down the lid flap against the base flap, there will be some misalignment of the characters with the holes that they previously lay in, creating gaps that are readily noticeable.Type: GrantFiled: May 1, 2006Date of Patent: March 29, 2011Assignee: Pactiv CorporationInventor: Terry Vovan

Patent number: 7909164Abstract: Nestable packaging lids are described. Generally, the packaging lids include a generally planar lid member having an upper surface and a lower surface, a plurality of dome expansions extending upwardly from the lid member, and a plurality of elongate projections extending downwardly from the lower surface of the lid member. Each dome expansion defines a downwardly facing recess and includes a base perimeter defining a base center, and the dome expansions are arranged in longitudinal rows and transverse columns. In an implementation, at least one projection is disposed transversely between a longitudinally adjacent pair of dome expansions and at least one projection is disposed longitudinally between a transversely adjacent pair of dome expansions.Type: GrantFiled: April 1, 2005Date of Patent: March 22, 2011Assignee: Pactiv CorporationInventors: Alan Andrews, David Furstoss

Patent number: 7904996Abstract: A slider is adapted for use with a reclosable fastener for bags containing material. The reclosable fastener includes a first track and a second track. The first track includes a first profile, while the second track includes a second profile. The first and second profiles are releasably engageable to each other. At least one of the first and second profiles has an interior portion. The slider comprises a body that includes a top, a first side, a second side and a separation member on an underside of the top. The separation member is adapted to open and close the fastener and includes a slider finger that extends generally downwardly from the top. The slider finger extends into an interior portion of the first profile so as to assist in removing material trapped in the interior portion of the first profile when closing the reclosable fastener.Type: GrantFiled: December 29, 2009Date of Patent: March 15, 2011Assignee: Pactiv CorporationInventors: David V. Dobreski, Toby R. Thomas, David P. Cameron

Publication number: 20110033138Abstract: A reclosable package comprises a first panel having first and second side sections and a second panel having first and second side sections. The first panel opposes the second panel and is joined to the second panel along the first and second side sections. A bottom extends between the first and second side sections of the first and second panels with the first and second panels joined to each other. A mouth is disposed opposite the bottom and extends between the first and second side sections of the first second panels. A closure member extends along the mouth, with the closure member including a first fin joined to the first panel and second fin joined to the second panel. A sealing member having a first and second ends is disposed proximate the mouth. The ends of the sealing member can be attached to the fin or panel such that at least one of the first end or second ends of the sealing member is attached with peelable seal.Type: ApplicationFiled: October 22, 2010Publication date: February 10, 2011Applicant: Pactiv CorporationInventors: David Cameron, Craig Soller, Michael Bohn, Roger E.

Patent number: 7878355Abstract: Foldable container including a base having a first base portion and an opposing second base portion. The base has a base surface free of hinge lines between the first base portion and the second base portion. A sidewall surrounds the base and extends generally upward from the base to define a compartment. A rim having a first rim portion and an opposing second rim portion is disposed proximate the top edge of the sidewall. At least one transition region is formed in the sidewall to allow the first base portion to pivot between an open position and a closed position, When in the open position, the container defines a plate. When in the closed position, the first base portion defines at least a portion of a cover relative to the second base portion.

Patent number: 7846987Abstract: Expanded and extruded biodegradable polymer foams are obtained using biodegradable polymers and environmentally benign non-VOC methyl formate as a blowing agent. The blowing agent can be a blend further including at least one co-blowing agent, preferably an environmentally friendly species (e.g., non-VOC), which 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 include any combination of methyl formate and one or more co-blowing agents. The polymer foam can include a biodegradable polymer or its blends with other biodegradable polymers or conventional (non-biodegradable) polymers. The methyl formate-based blowing agent blends produce stable foams for various applications, including containers, packaging systems, as well as for insulation and protective cushioning.Type: GrantFiled: December 12, 2007Date of Patent: December 7, 2010Assignee: Pactiv CorporationInventor: Y.
