Abstract: A resealable vacuum-tight closure mechanism has 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.

Abstract: A storage bag includes first and second side surfaces that form an interior of the bag with an opening to the interior. A first closure profile connected to the first side surface and positioned adjacent to the opening of the bag has a top edge and includes an interlocking member that extends between the first and second sides. A second closure profile connected to the second side surface and positioned adjacent to the opening of the bag has a top edge and includes an interlocking member. A lip extends between the interlocking member and the top edges of the first and second closure profiles. The lip is a single, continuous web having certain dimensions from the interlocking member to the top edges of the first and second closure profiles.

Abstract: A process of manufacturing a roll of plastic bags. The process includes forming a tubular blown film, and collapsing the tubular blown film so that the tubular blown film includes a first side, a second side, a first edge, and a second edge. Openings are cut in the collapsed tubular blown film, and sealing closure mechanisms are inserted through the openings into the collapsed tubular blown film. The sealing closure mechanisms are then fixed to the collapsed tubular blown film.

Abstract: A storage bag includes first and second sidewalls having a top edge, a top portion, and a bottom portion. The bottom portion of the first sidewall includes at least one shift region about which the bag is capable of shifting. The shift region includes a score line, an indentation, or a crimp formed into the first sidewall. The top portions of the sidewalls include a cuff region includes a textured patterned band to provide a visual cue to a user as to where to fold and to cuff the bag. The bag shifts between (i) a flat configuration with the sidewalls positioned adjacent to each other, and (ii) a stand-up configuration with the sidewalls separated from each other. In the stand-up configuration, the bag has a substantially flat base. The cuff region can be shifted to a cuffed position with the cuff region forming the opening to the bag.

Abstract: A system and process for making a container or pouch that separates the cutting and sealing steps into two distinct steps with a separate step of rotating the container or pouch template 90 degrees relative to a direction of travel between the cutting and sealing steps.

Abstract: A storage bag is provided with visually distinct features that facilitate opening and closing of the bag. The visually distinct features result in the bag having an asymmetric appearance about one or more imaginary lines along the bag. The visually distinct features and resulting asymmetries provide a visual cue for a user as to how the bag should be grasped when being opened. The visually distinct features, as well as other features of the bag, may also facilitate manufacturing of the bag.

Abstract: A storage bag includes first and second side surfaces that form an interior of the bag with an opening to the interior. A first closure profile connected to the first side surface and positioned adjacent to the opening has a top edge and includes an interlocking member that extends between first and second sides of the first closure profile forms a lip between the interlocking member and the top edge. A second closure profile connected to the second side surface and positioned adjacent to the opening of the bag has a top edge and includes an interlocking member. A first portion of the lip of the second closure profile smoothly transitions into a third portion of the lip of the second closure profile, and the third portion of the lip of the second closure profile smoothly transitions into a second portion of the lip of the second closure profile.

Abstract: A storage bag shifts between a flat configuration with first and second sidewalls positioned adjacent to each other, and a stand-up configuration with the sidewalls separated. In the stand-up configuration, the bag has a substantially flat base (i) formed by the bottom portion of the first and second sidewalls, and (ii) outlined by at least one of the shift regions of the sidewalls. An angle ? is defined between each of (i) the first shift region of the first sidewall and an adjacent edge of the bag and (ii) the first shift region of the second sidewall and an adjacent edge of the bag, and (b) a differing angle ? is defined between each of (i) the second shift region of the first sidewall and a bottom edge of the bag and (ii) the second shift region of the second sidewall and the bottom edge of the bag.

Abstract: A storage bag includes a first sidewall having a top edge and a bottom edge, and a plurality of shift regions about which the bag is capable of shifting. At least one of the shift regions includes one of a score line, an indentation, and a crimp formed into the first sidewall, and extends a distance along the first sidewall starting from near the bottom edge of the first sidewall. A second sidewall is connected to the first sidewall so as to form an interior of the bag with an opening to the interior and having a top edge and a bottom edge. At least one of the shift regions of the first and second sidewalls extends across and intersects with another of the shift regions of the first and second sidewalls, to facilitate shifting of the bag. The bag shifts between a flat configuration, and a stand-up configuration.

Abstract: A storage bag is provide with features that facilitate unsealing an opening of the bag, including shaped lips and visual cues for areas that the lips that should be grasped during the unsealing process. The visual cue may include relative coloring of portions of the lips of the bag. The storage bag also includes features that facilitate sealing the opening of the bag, including textured areas and dimples. Such features may provide visual cues, tactile feedback and/or audio feedback in order to facilitate the sealing process.

Abstract: A storage bag includes first and second sidewalls that are directly connected without a pleat between the sidewalls at a bottom of the bag. The bag includes a plurality of shift regions at bottom portions of the sidewalls. The bag can be moved about the shift regions such that the bag is shiftable between a flat configuration with the first and second sidewalls positioned adjacent to each other and a stand-up configuration with the first and second sidewalls separated from each other. In the stand-up configuration, the bag is shifted about the shift regions such that a substantially flat base is formed for the bag. The stand-up configuration is thereby achieved without a pleat being provided between the sidewalls at a bottom of the bag. The bag further includes a cuff region that is disposed below the top of the bag for cuffing of the top of the bag.
