20080240625 | Slider zipper with hinged secondary locking profile - The zipper assembly for a reclosable package or bag includes a zipper with exterior interlocking elements and flanges, and typically includes a slider. Additionally, a hinged secondary zipper formed from interior interlocking elements. A first interior interlocking element is hinged by an interior flange with respect to the first flange while the second interior interlocking element is attached to the second flange. The hinging of the secondary zipper causes forces or loads from within the reclosable package or bag to configure the secondary zipper in a shear configuration, rather than a peeling configuration, thereby increasing the interior burst strength of the package or bag. | 10-02-2008 |
20090052812 | Various gusset seals or treatments for reclosable packages - Reclosable gusseted packages or bags have improved resistance to leaking or spilling through the gussets by sealing the gussets together through apertures in the gusset walls, by sealing the zipper flanges together through apertures passing through the gussets in the package or bag, by folding portions of the gussets, or by sewing the gussets shut in areas proximate to the zipper. | 02-26-2009 |
20090067761 | High burst closure assembly for large packages - The present disclosure relates to a high burst closure which allows for bottom filling of packages, such as large bags, and further provides increased resistance to damage from the dropping or shock loading of the filled package. This is achieved by providing profiles that combine an upper portion of one profile and its related flange, so as to form a juncture above a peel seal joining one profile to the other, so that external forces on a package or bag from bottom filling or shock loading are directed toward the juncture thereby causing a shear force against the peel seal or other frangible connection, thereby increasing the resistance of the package to external forces. | 03-12-2009 |
20090257691 | HIGH BURST CLOSURE ASSEMBLY FOR LARGE PACKAGES - The present disclosure relates to a high burst closure which allows for bottom filling of packages, such as large bags, and further provides increased resistance to damage from the dropping or shock loading of the filled package. This is achieved by providing profiles that combine an upper portion of one profile and its related flange, so as to form a juncture above a peel seal joining one profile to the other, so that external forces on a package or bag from bottom filling or shock loading are directed toward the juncture thereby causing a shear force against the peel seal or other frangible connection, thereby increasing the resistance of the package to external forces. | 10-15-2009 |
20090258772 | METHOD OF PRODUCING HIGH BURST ZIPPER ASSEMBLIES FOR LARGE RECLOSABLE PACKAGES - The present disclosure relates to a method for producing a high burst slider zipper which allows for bottom filling of reclosable packages, such as large bags, and further provides increased resistance to damage from the dropping or shock loading of the filled package. This is achieved by providing a peel seal or other frangible or separable connection between the zipper profiles, and by sealing a portion of one of the flanges to itself by a hard seal above the peel seal. This causes the external forces on a bag from bottom filling or shock loading to be directed toward the hard seal and further directed so as to cause a shear force against the peel seal, thereby increasing the resistance of the package to external forces. | 10-15-2009 |
20090263051 | HIGH BURST ZIPPER ASSEMBLY FOR LARGE RECLOSABLE PACKAGES - The present disclosure relates to a high burst slider zipper which allows for bottom filling of reclosable packages, such as large bags, and further provides increased resistance to damage from the dropping or shock loading of the filled package. This is achieved by providing a peel seal or other frangible or separable connection between the zipper profiles, and by sealing a portion of one of the flanges to itself by a hard seal above the peel seal. This causes the external forces on a bag from bottom filling or shock loading to be directed toward the hard seal and further directed so as to cause a shear force against the peel seal, thereby increasing the resistance of the package to external forces. | 10-22-2009 |
20100021093 | RECLOSABLE FLEXIBLE PACKAGING HAVING HEADER WITH CUSTOMER TAKEAWAY - A package is provided of the type with a tear-away header which is separated from the product contents of the package by a zipper sealed to the interior of the package walls. The space within the header is used to package and an item such as a toy, game card, game token, coupon, or punched foam strip which can be used as a promotional or gift item. In this way, the item packaged within the header is kept separate from the product contents of the package. | 01-28-2010 |
20100069211 | METHOD OF PRODUCING HIGH BURST ZIPPER ASSEMBLIES FOR LARGE RECLOSABLE PACKAGES - The present disclosure relates to a method for producing a high burst slider zipper which allows for bottom filling of reclosable packages, such as large bags, and further provides increased resistance to damage from the dropping or shock loading of the filled package. This is achieved by providing a peel seal or other frangible or separable connection between the zipper profiles, and by sealing a portion of one of the flanges to itself by a hard seal above the peel seal. This causes the external forces on a bag from bottom filling or shock loading to be directed toward the hard seal and further directed so as to cause a shear force against the peel seal, thereby increasing the resistance of the package to external forces. | 03-18-2010 |
20100166341 | Reclosable Vacuum Storage Bag Having Flat Resealable Means - A reclosable vacuum storage bag that can be hermetically sealed by flat resealable means that extend across the full width of the bag. The flat resealable means are designed to provide a barrier to prevent ambient air from leaking into the evacuated interior volume of the bag. The storage bag is also provided with a plastic zipper. The flat resealable means can be arranged on the product side of the zipper, on the user side of the zipper, or in between two zippers installed in the storage bag. | 07-01-2010 |
