20090238702 | FOOD STORAGE BAG VACUUM PUMP - A vacuum pump comprises a casing having a bottom forming an aperture therein and a chamber slidably coupled within the casing. The chamber has a bottom forming an aperture therein. The vacuum pump further comprises a piston slidably coupled within the chamber. The piston includes an upper portion generally parallel to the chamber bottom. The piston further includes a hollow shaft extending from a bottom surface of the upper portion. The shaft has a first end adjacent to the upper portion and a second opposing end. The shaft is configured to fit within the chamber aperture and the casing aperture. The shaft includes at least one aperture positioned at the first end. The second end of the shaft is coupled to the casing at the casing aperture. The vacuum pump is configured to evacuate air from a flexible storage container by pushing the chamber in a downward direction. | 09-24-2009 |
20100209021 | POLYMERIC BAGS WITH PRESSURE RELIEF VALVES - Polymeric bag includes first and second opposing body panels attached to each other along a pair of opposing sides and a bottom bridging the sides, a reclosable fastener extending along a mouth formed opposite the bottom, a pressure relief opening defined in the first body panel, and a pressure relief valve attached to the first body panel. The valve includes a cover member to cover the opening. The cover member includes an upper layer and a lower layer, the lower layer including a first portion attached to the body panel and a second portion contiguous with the first portion but not attached to the body panel. The upper layer has a first end hingedly connected to the second portion of the lower layer on a first side of the pressure relief opening, and the upper layer has a second end fixedly attached on a second side of the pressure relief opening opposite the first side with the upper layer covering the pressure relief opening. An additional aspect includes a seal line extending proximate the pressure relief opening. | 08-19-2010 |
20110317942 | SLIDER TRACK WITH IMPROVED SEAL STRENGTH - Rolling action reclosable fastener comprises a male track including a male profile, a female track including a female profile, and a slider disposed on the male and female tracks to matingly engage the male profile and the female profile. The slider includes a back and a pair of sidewall depending therefrom. The slider also includes a separator finger depending from the back between the pair of sidewalls and shaped along its length to first press together a bottom of the male and female profiles and then roll the profiles closed toward a top thereof as the slider moves toward the closed condition. The male profile comprises a base and a rib with a hook portion having an inwardly-directed surface including a projection defining an engagement surface. The female profile comprises a base and a first flange having an inwardly-directed surface including a projection defining an engaging surface. The engaging surface of the female track engages the engagement surface of the male track when in a closed condition with at least a portion of the male profile received by at least a portion of the female profile. A reclosable plastic bag with a rolling action reclosable fastener is also provided. | 12-29-2011 |
20140259571 | Reclosable Fastener And Reclosable Bag Having Same - Reclosable fastener includes a first track having a first engagement profile and a first retention feature extending therefrom, the first retention feature disposed substantially level with or above a bottom of the first engagement profile and having a first outward extension and a first upward extension extending upwardly from the first outward extension; a second track having a second engagement profile and a second retention feature extending therefrom, the second retention feature disposed substantially level with or above a bottom of the second engagement profile and having a second outward extension and a second upward extension extending upwardly from the second outward extension; and a slider disposed on the first and second tracks and interlocking the first and second engagement profiles together when moved from an open position toward a closed position along the first and second tracks. A method of forming a reclosable fastener is also provided. | 09-18-2014 |
20140270588 | End Stops For Reclosable Fastener And Reclosable Bag Having Same - Reclosable fastener assembly includes a fastener comprising a pair of interlocking tracks including a first track having a male profile and a second track having a female profile, the fastener having a height and a width when the tracks are interlocked, a slider slidably mounted to the tracks for movement between a closed position and an open position, and at least one end stop located at an end of the fastener, the end stop formed integrally from at least one of the first and second tracks, the end stop having a wedge shape with a first end, a second end, and a lateral extent, the first end being proximate the fastener and having a height no greater than the height of the fastener, the end stop having a decreasing height from the first end to the second end, and the lateral extent extending beyond the width of the fastener. | 09-18-2014 |
20140270589 | Vertical Action Reclosable Fastener And Reclosable Bag Having Same - Reclosable fastener includes a first track including a first engagement profile having a first hook portion opening in a first direction along a reference axis substantially perpendicular to a burst direction of the fastener and a second track including a second engagement profile having a second hook portion opening in a second direction opposite the first direction along the reference axis and configured to engage the first hook portion in a closed configuration. The first and second hook portions are configured to engage each other when the first and second tracks are urged toward each other along the reference axis, and the first and second hook portions are configured to disengage each other when the first and second tracks are urged away from each other along the reference axis. A reclosable bag having a reclosable fastener and a slider for a reclosable fastener are also provided. | 09-18-2014 |
