    Abstract: A storage bag device is provided to facilitate improved opening of a re-sealable storage bag. The device comprises a uni-body bag container having a set of ring tabs attached thereto, and a sealing means disposed on opposing inner surfaces of said bag container. The bag container may be any resilient and reusable bag with a single opening at the top, defined by the bag container's upper edges. Ring tabs extending from the center of said upper edges are designed to receive at least one of a user's fingers. To open the bag, a user pulls the ring tabs outward in opposing directions, thereby causing the sealing means to disengage and open the bag. The sealing means may then be firmly pressed together to close the container and create an air and moisture tight seal.

If the first or second film becomes tucked into the groove left by the perforations such that the gripper ridges are difficult to access even after tearing the perforations, then the end of the opening may be flexed up or down, thereby causing separation of the convex area and concave area to provide access to the gripper ridges.

  • Patent number: 7017240
    Abstract: A container (120) includes a closure device (121). The closure device includes interlocking fastening strips (130, 131) and a slider (132) slidably disposed on the fastening strips for facilitating the occlusion and deocclusion of the fastening strips. The slider includes a separator (133) that facilitates the deocclusion of the fastening strips. The container includes a seal (129) to provide a leak-proof closure by facilitating the occlusion of the closure device (121) after the slider (132) has been moved in the occlusion direction (114) and reached the end of the fastening strips. The seal (129) includes a curved portion that further facilitates the leak-proof closure. Additionally, a tactile indication that the closure device (121) has been fully occluded is given as the separator (133) passes over the seal (129). Similarly, an audible indication may also be provided. The seal may be accomplished by heat sealing, ultrasonic sealing or adhesives that attach the sidewalls together.

  • Patent number: 6986920
    Abstract: A composite web of packaging material for making gusseted packages having openable and reclosable interlocking seals, the seals having male and female portions, snap detents, and formed transversely to the direction of material flow. The packaging material is provided at package length intervals with thermoformable strips secured thereto transversely to the running length of the packaging material, and is fed to a modified standard vertical form, fill and seal packaging machine with gussets forming tooling where the packaging material is formed into a bag with the thermoformable strips inside at the upper end of the bag, product deposited into the bag, the bag sealed, the reclosable interlocking seal formed, and the bag severed from the next bag being formed. The reclosable seal provides auditory and tactile indications of seal closing. Some packages are formed with the thermoformable strips in the gusset, and some are formed with the gusset free of strip material.

  • Patent number: 6954969
    Abstract: A reclosable fastener strip for securing to a film web comprises first and second flangeless, elongated profile strip having a plurality of interlocking hooks, recesses and protuberances. Each hook, as extruded, has a half arrowhead-shaped tip, a concave or partial-concave tail, and a generally upstanding neck connecting the tip and tail. Each recess has a base with a pair of generally upstanding neck elements disposed on opposite ends of the base. The base does not extend laterally beyond the neck elements. Each protuberance, as extruded, has a rounded tip, a concave or partial-concave tail, and a generally upstanding neck portion connecting the tip and tail. The profile strips are readily secured to the web without entrapping air between the profile strips and the film web and form an airtight and watertight seal. The interlocking hooks, recesses and protuberances are dimensioned to provide and airtight and watertight seal upon interconnection thereof.

  • Patent number: 6951420
    Abstract: A plastics bag has at least one seal (34, 36) extending parallel to the mouth of the bag to close the sides. Preferably, a reclosable zipper seal (36) is provided below a top seal (34). A novel tag is provided, secured to the zipper seal (36) and extending through the top seal (34). The tag (11) is generally M-shaped in cross-section with its outside legs secured to the seals and with an inner tuck which the consumer can withdraw from the mouth of the bag and break open to make an access hole through the seal or seals into the interior of the bag to facilitate full opening of the mouth of the bag. Methods of manufacturing such bags are also described, particularly for use with form-fill-seal machines.

  • Patent number: 6767131
    Abstract: A multi-compartment reclosable bag that includes closures that effectively separate the compartments' contents and reduces accidental mixing is described. In addition, perforations in the bag facilitate selective dispensing of a portion of the bag's contents. The reclosable bag includes first and second panels joined along their side edges. An upper closure comprises a male profile having opposing first and second barbs. The first barb is substantially longer than the second barb. An intermediate closure is positioned between the upper closure and a bottom edge of the bag. The intermediate closure comprises a male profile having opposing third and fourth barbs. The third barb is substantially longer than the fourth barb. The first barb is oriented downwardly and the third barb is oriented upwardly for reducing accidental opening of the closures.

  • Patent number: 6709157
    Abstract: A closure arrangement for a reclosable polymeric bag is disclosed, the closure arrangement comprising convex and concave areas that facilitate opening the bag. To initially open the bag, first and second films are separated from each other by tearing perforations. Next, interlocked closure profiles are detached from each other by grabbing onto gripper ridges and pulling the opening of the bag apart. If the first or second film becomes tucked into the groove left by the perforations such that the gripper ridges are difficult to access even after tearing the perforations, then the end of the opening may be flexed up or down, thereby causing separation of the convex area and concave area to provide access to the gripper ridges.
