20080232722 | VENTING DOUBLE ZIPPER AND RECLOSABLE STORAGE BAG USING SAME - A reclosable storage bag and zipper tape for use in conjunction with same is disclosed. The reclosable bag includes first and second panels which are sealed about bottom, left, and right edges leaving an open top. The closure system further includes first and second closure assemblies or zippers which can be individually or simultaneously closed to seal the contents within the bag. Even after the first and second zippers are engaged thereby closing the bag, excess air within the bag can be removed simply be manually compressing the bag and thereby forcing the air through the vent apertures provided between the zippers. A valve internal to the closure system may be provided proximate the vent apertures and open upon sufficient application of pressure thereby allowing for air to be evacuated from the bag. | 09-25-2008 |
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 |
20090053445 | PLASTIC BAGS AND ZIPPERS MANUFACTURED OF A POLYMERIC MATERIAL CONTAINING INORGANIC FILLER - A polymeric substrate is disclosed that comprises a plastic matrix and an inorganic filler dispersed in the plastic matrix, wherein the polymeric substrate exhibits improved OTR and WVTR. The disclosed polymeric substrate may be used in manufacturing of plastic containers, such as plastic bags for containing food products. Preferably, the improved OTR and WVTR of the polymeric substrate contribute to better storage performance of the plastic bags, eg. keeping the food products within the plastic bags from degradation and/or dehydration | 02-26-2009 |
20090265898 | CLOSURE MECHANISM HAVING INTERNAL PROJECTIONS TO DECREASE SLIDER PULL-OFF - A slider actuated closure mechanism includes internal projections that extend from interior sides of closure elements and retention members that extend from exterior sides of the closure elements. A slider is disposed over the first and second closure elements and includes first and second sidewalls each including a shoulder inwardly extending from a distal end thereof. When the slider is disposed over the first and second closure elements, the first sidewall and the first closure element are minimally horizontally separated by a distance d | 10-29-2009 |
20100014786 | VENTING CLOSURE MECHANISM - A venting closure mechanism for a pouch includes first and second closure profiles that interlock and third and fourth closure profiles that interlock. A sealing flap extends from the first closure element between the first and third closure profiles and engages the second closure element to form a releasable gastight seal therebetween. When the first and second closure elements are occluded, a first plurality of longitudinally spaced first exhaust channels is disposed on a product-side of the sealing flap and a second plurality of longitudinally spaced second exhaust channels is disposed on a user-side of the sealing flap. A first pouch sidewall is attached to the first closure element at an exterior surface thereof between a user-side edge of the first closure element and the sealing flap. An interior surface of the first pouch sidewall is textured with a pattern that provides flow channels therealong. | 01-21-2010 |
