20080226203 | Pouch and airtight resealable closure mechanism therefor - A pouch has an airtight elongate closure mechanism adapted to provide vacuum retention within an interior of the pouch over an extended period of time when sealed. The closure mechanism includes a first pair of interlocking members that resealably mate together, a second pair of interlocking members that resealably mate together, and sealing members that form an air tight seal disposed between the first and second pairs of interlocking members. The closure elements may be connected with opposing sidewalls of the pouch in a manner designed to provide differential opening and closing forces. The pouch may also include a check valve and air evacuation channels to aid in evacuating air from the interior. | 09-18-2008 |
20080310770 | Valve for a recloseable container - A valve for a reclosable container comprises first and second opposing layers of a film material, wherein an overlap region of the second layer overlaps the container, and the first layer is sealed to the second layer around a portion of the second layer. The second layer is sealed to the container around a periphery of the overlap region, and opposing surfaces of the first and second layers form a substantially airtight seal therebetween upon direct contact of the layers. First and second offset apertures extend through the first and second layers, respectively. One of the first and second apertures is in fluid communication with an interior of the container and the other of the first and second apertures is in fluid communication with an exterior of the container. Vacuum pressure disposed over both of the first and second apertures causes the first layer to separate from the second layer to allow air to exhaust from the container. | 12-18-2008 |
20080310771 | Offset closure mechanism for a reclosable pouch - An offset resealable closure mechanism adapted to provide an airtight seal for a pouch includes a first elongate closure element and a second elongate closure element. The first elongate closure element includes a first elongate closure profile extending therefrom and a second elongate closure element includes first and second legs extending therefrom to define a channel. A sealing flange extends across the channel and includes a slit therethrough adapted to receive the first elongate closure profile. The sealing flange forms an airtight seal with the first elongate closure profile when the closure mechanism is occluded. | 12-18-2008 |
20080310773 | Airtight closure mechanism for a reclosable pouch - An airtight closure mechanism for a reclosable pouch includes first and second complementary closure elements, the first closure element comprising a first interlocking profile and the second closure element comprising a complementary second interlocking profile. First and second sealing sections are disposed on respective complementary sides of the first and second interlocking profiles. The first sealing section includes a first protuberance having a first distal surface, a second protuberance having a second distal surface, and a sealing flange attached to and extending between the first and second distal surfaces of the first and second protuberances, respectively. The second sealing section includes a sealing member disposed on a base of the second closure element. The sealing member is located a distance from the second interlocking profile that places a distal surface thereof between the first and second protuberances when the first and second interlocking profiles are occluded. Additionally, when the first and second interlocking profiles are occluded, the distal surface urges against the sealing flange to form an airtight seal therebetween. | 12-18-2008 |
20080310774 | Pouch with a valve - A pouch with a valve includes first and second pouch sidewalls sealed to one another to define an opening. A resealable closure mechanism is attached to inner surfaces of the first and second sidewalls proximate the opening to define a pouch interior opposite the opening. A channel extends from the interior to the opening between a section of the first closure element and the first sidewall. A pleated thermoplastic member is sealingly disposed in the channel and has an aperture disposed through the member. A fluid path may provide direct fluid communication between the interior and an exterior of the pouch, wherein the fluid path passes through an edge of the pouch defined by at least one of the first or second pouch sidewalls. A valve is sealingly disposed in the fluid path, wherein the valve comprises a pleated thermoplastic member attached to at least one of the first or second pouch sidewalls and having an aperture disposed through the pleated thermoplastic member to provide fluid communication between the interior and the exterior of the pouch. | 12-18-2008 |
20080310776 | Flow channels for a pouch - A pouch includes first and second opposing pouch walls and a plurality of flow channel protuberances that defines a flow channel between the first and second pouch walls and is disposed on an inner surface of at least one of the first or second pouch walls. At least one of the plurality of protuberances includes a first component extending from the at least one of the first or second pouch walls and a second component extending at a non-zero angle from the first component. The flow channel extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening. | 12-18-2008 |
20100284632 | Pouch And Airtight Resealable Closure Mechanism Therefor - A pouch has an airtight elongate closure mechanism adapted to provide vacuum retention within an interior of the pouch over an extended period of time when sealed. The closure mechanism includes a first pair of interlocking members that resealably mate together, a second pair of interlocking members that resealably mate together, and sealing members that form an air tight seal disposed between the first and second pairs of interlocking members. The closure elements may be connected with opposing sidewalls of the pouch in a manner designed to provide differential opening and closing forces. The pouch may also include a check valve and air evacuation channels to aid in evacuating air from the interior. | 11-11-2010 |
20110085748 | Flow Channels for a Pouch - A pouch includes first and second opposing pouch walls and a plurality of flow channel protuberances that defines a flow channel between the first and second pouch walls and is disposed on an inner surface of at least one of the first or second pouch walls. At least one of the plurality of protuberances includes a first component extending from the at least one of the first or second pouch walls and a second component extending at a non-zero angle from the first component. The flow channel extends between an opening of the pouch and a portion of an interior of the pouch that is spaced from the opening. | 04-14-2011 |
