Abstract: The present invention provides a resealable closure structure (999) which provides at least one region of continuous gas-sealing abutment (900) upon engaging the interengaging members (988, 978) of the closure. The closure provides a region of gas sealing abutment by one or more of. (i) mechanical abutment of closure features (1010, 1013) and associated therewith a caulking composition (990) and/or a sealing material (945); and (ii) defining a void region (1030) by proximity of closure features when interengaging members of the closure are engaged (1020, 1021) which has gas-sealingly infiltrated thereinto a caulking composition (945).

Abstract: The present invention provides a storage system having a storage device having at least one polymeric sheet sealed along a portion of its' periphery to provide an opening to a storage space; a resealable closure structure adapted to seal the opening to the storage space, the resealable closure structure comprising selectively engaging male and female profiles and a sealing compound comprising liquid silicone and at least one filler in proportions suitable for at least incidental contact to food items contained within the storage space; a vacuum valve assembly disposed on the polymeric sheet; a stand-off structure disposed adjacent to the vacuum valve assembly, wherein the stand-off structure has a series of raised surfaces facing the vacuum valve assembly; a portable vacuum pump assembly structured to engage the vacuum valve assembly; and a liquid separator assembly coupled to the portable vacuum pump assembly.

Abstract: Resealable closures for use in sealing polymeric packages are provided. The resealable closures include a sealant material that restricts fluid flow into and out of the resealable closure.

Abstract: A reclosable polymeric package having a zipper closure at its mouth and a venting feature that allows air or other fluid to be vented from the package interior when the zipper closure is sealed. In one example, the venting feature includes vents covered by a tape intermittently secured to the package to define fluid passageways. Methods of use are provided.

Abstract: A reclosable package, formed from at least one polymeric sheet, having a closure and a vacuum valve. The vacuum valve comprises a port, the port being aligned with an aperture in the first sidewall of the package. The vacuum valve allows gas to be removed from inside the package via a vacuum pump. A gas-impermeable layer, overlaying at least one of the aperture and the port, restricts gaseous communication between the vacuum valve and the inside of the package.

Abstract: A method of making and filling reclosable packages using a duplex machine includes the steps of providing a zipper profile, package film and a plurality of sliders; feeding the zipper profile; applying the sliders to the zipper profile; coupling the zipper profile to the folded web; sealing two edges of the folded web to form adjacent pouches; filling the pouches; sealing the pouches proximate a third edge thereof; and separating the pouches in order to form individual packages. The method employs a single rotating slider applicator having a programmable servo motor which is programmed in order to synchronize the application of the sliders to the moving zipper profile with the two at a time form, fill, seal and separate packaging operations of the duplex machine. A duplex machine is also disclosed.

Abstract: The present invention provides a vacuum storage bag system having a storage device having at least one polymeric sheet sealed along a portion of its' periphery to provide an opening to a storage space; a resealable closure structure adapted to seal the opening to the storage space, the resealable closure structure comprising selectively engaging male and female profiles and a sealing compound comprising liquid silicone and at least one filler in proportions suitable for at least incidental contact to food items contained within the storage space; a vacuum valve assembly disposed on the polymeric sheet; a stand-off structure disposed adjacent to the vacuum valve assembly, wherein the stand-off structure has a series of raised surfaces facing the vacuum valve assembly; a portable vacuum pump assembly structured to engage the vacuum valve assembly; and a liquid separator assembly coupled to the portable vacuum pump assembly.

Abstract: A reclosable package having a zipper closure, and optionally a slider device to open and close the zipper closure. The package includes a sealant stripe, which can be a peal seal, and a one-way fluid valve. In use, the valve is used to remove air from the interior of the package, and the sealant strip, in combination with the zipper closure, provides a better seal than the zipper alone. The package may be part of a storage system that includes stand-off structures adjacent to the valve, a vacuum pump assembly, and a liquid separator assembly coupled to the vacuum pump assembly.

Abstract: A reclosable package having a zipper closure with a venting feature that allows air or other fluid to be vented from the package interior. In one example, the venting feature includes vents in the package wall covered by a perforated tape intermittently secured to the package to define fluid passageways. A second tape covers the perforated tape. Methods of using are provided.
