383059000 | Including auxiliary means for forming leakproof closure seal | 8 |
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 |
20090324141 | RECLOSABLE VACUUM-TIGHT POUCH AND RESEALABLE VACUUM-TIGHT CLOSURE MECHANISM THEREFOR - A resealable vacuum-tight closure mechanism comprises a first closure element that includes a first base and a second closure element that includes a second base. A first contact surface on a first interlocking profile depends from the first base and a second contact surface on a second interlocking profile depends from the second base. The first and second contact surfaces provide a maximum occlusion distance when the first and second interlocking profiles are in an occluded state. A first sealing member extends from the first base, has a first length, is spacedly disposed from the first interlocking profile, and has a first sealing surface disposed thereon. A second sealing member extends from the second base, has a second length, is spacedly disposed from the second interlocking profile, and has a second sealing surface disposed thereon that is complementary to the first sealing surface. A sealing reservoir protrusion is disposed between the first sealing member and the first interlocking profile and has a volume sufficient to form a first gastight seal in a first occluded space between the first and second closure elements and bounded by the first and second occluded sealing members and the first and second occluded interlocking profiles upon formation of an end-stomp at an end of the first and second closure elements. A sum of the first and second lengths of the respective first and second sealing members is greater than or about equal to a length necessary to maintain a second gastight seal between the first and second sealing surfaces when the first and second interlocking profiles are in the occluded state. | 12-31-2009 |
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 |
20110002558 | HOODED BAG WITH RECLOSABLE TOP - A bag has an elongated bag opening held closed by a fastener assembly, wherein the fastener assembly has a first fastening member and a second fastening member attached along respective sides of the bag opening, and a sliding actuator to interlock or to unlock the first fastening member and the second fastening member. The bag opening is covered by a hood having a section covering the bag opening, and having other sections secured to the first fastening member and the second fastening member, to resist tampering by cutting or peeling, and the sliding actuator protrudes outwardly from the hood for inspection to detect tampering. | 01-06-2011 |
20110091136 | SEALABLE ENCLOSURE - A pocket closure assembly can have a pocket and a first member coupled to the pocket, where the first member has a first surface. A second member may be rotatably coupled to the first member, where the second member has a second surface that mates with the first surface to form a seal for the pocket if the second member is rotated to a closed position. | 04-21-2011 |
20120128273 | Self Sealing Waterproof Bag - A waterproof self sealing container sealed by magnet to magnet contact, making the container airtight and water resistant. The water resistant container has a body made of flexible water resistant material. The body is formed as a sheet. An opening is formed at an end of the body. The body opening has a body opening first side and a body opening second side. A first magnet strip is bonded to the body opening first side. A first bonding layer bonds to the body. The first magnet strip is bonded to the first bonding layer and wherein the first bonding layer is bonded to the body opening first side. A second magnet strip is bonded to the body opening second side. A second bonding layer is bonded to the body. | 05-24-2012 |
20130243354 | SELF SEALING WATERPROOF BAG - A waterproof self sealing container sealed by magnet to magnet contact, making the container airtight and water resistant. The water resistant container has a body made of flexible water resistant material. The body is formed as a sheet. An opening is formed at an end of the body. The body opening has a body opening first side and a body opening second side. A first magnet strip is bonded to the body opening first side. A first bonding layer bonds to the body. The first magnet strip is bonded to the first bonding layer and wherein the first bonding layer is bonded to the body opening first side. A second magnet strip is bonded to the body opening second side. A flap magnet contact area is formed where the first magnet strip and the second magnet strip are free from the sidewalls of the body. | 09-19-2013 |
20140133783 | Sift-Resistant Bag - A sift-resistant valve bag is disclosed herein. The bag includes an upper end, the upper end being at least partially closed, a lower end opposite the upper end, the lower end being closed, a valve in the upper end, the valve being configured to receive flowable material for filling the bag, and a patch in the upper end and opposite from the valve, the patch being configured to restrict leakage of material flowing through the valve, wherein the patch includes a cuff. | 05-15-2014 |
