Abstract: 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.

Abstract: A hand-held vacuum device is disclosed that includes a housing to hold an electric motor operable to drive a piston pump that is configured to draw a substantially continuous vacuum for each complete cycle of the piston pump. The hand-held vacuum device also includes an expansion chamber releasably connected to and in fluid communication with the housing and a vacuum interface that has a vacuum connector in fluid communication with the expansion chamber and is configured to releasably couple to a valve disposed on a container. The expansion chamber separates air and liquid from a fluid drawn into the expansion chamber.

Abstract: 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.

Abstract: A closure mechanism for a reclosable pouch includes a female profile having first and second legs extending from a first base of a first closure element and a sealing flange attached to each of the first and second legs. A slit is disposed through the sealing flange to define a first sealing flap that depends from the first leg and a second sealing flap that depends from the second leg. A male profile extends from a second base of a second closure element. The male profile is adapted to engage a portion of at least one of the first and second sealing flaps to form a seal therebetween when the male and the female profiles are occluded. Further, a surface of the second base is configured to engage at least one of the first and second sealing flaps to form a seal therebetween when the male and the female profiles are occluded.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A pouch has an 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 a pair of sealing members that form an air tight seal separate from the interlocking members disposed between the first and second pairs of interlocking members. The closure members are connected with opposing panels of the pouch in a manner designed to provide differential opening and closing forces. The pouch may include a check valve and air evacuation channels to aid in evacuating air from the interior.

Abstract: A resealable closure mechanism includes first and second closure strips. The first closure strip includes a plurality of discontinuous closure elements and the second closure strip includes a plurality of discontinuous closure elements. One or more of the discontinuous closure elements of the first closure strip randomly engages one or more of the discontinuous closure elements of the second closure strip.

Abstract: A resealable closure mechanism includes a first closure including a plurality of profiles including two functional male closure profiles and a first plurality of non-functional male closure profiles, wherein at least one of the non-functional male closure profiles is disposed between the two functional male profiles. A second closure opposes the first closure and includes two female closure profiles configured to interlock with the functional male closure profiles. The non-functional male profiles are configured such that the female profiles cannot interlock therewith.

Abstract: A reclosable pouch comprises a body portion having first and second opposing bag walls, wherein each bag wall has an internal side. First and second closure mechanisms are disposed on the internal sides of the first and second bag walls, wherein the closure mechanisms are parallel and spaced between about 0.1 inch (2.54 mm) and 0.3 inch (7.62 mm) apart. Further, the first closure mechanism may have a first closure characteristic and the second closure mechanism may have a second closure characteristic different than the first closure characteristic.

Abstract: A container comprises a first container portion and a second container portion joined to the first container portion to define a sealed cavity therebetween. A coolant is disposed within the sealed cavity. The container further comprises a pressure relief apparatus operable to limit pressure in the sealed cavity.
