摘要:
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.

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.

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.

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.

A reclosable pouch includes interlocking male and female closure elements having elongate hollow closure profiles. The male closure profile has a hollow shaft section, and the female closure profile has a channel with at least one hollow side. Alternatively, a set of hollow male closure profiles may also form one or more female closure profiles therebetween. A set of pleated grip strips may be disposed adjacent the closure elements to aid in opening a pouch. The closure elements and grip strips may be integral with pouch sidewalls, may be secured and/or separately extruded on to, for example, a polymer, directly to pouch sidewalls, or may be secured to backing strips to form a closure strip, which may subsequently be secured to pouch sidewalls.
