Definitions

  • the present invention relates to plastic bags, and more particular!/ to an opening apparatus for use with a plastic bag, being reclosabie or not.
  • Thermoplastic bags are now commonplace for storing items such as foodstuff and the like.
  • the closure devices typically include registrable multiple profiles disposed on opposed inner surfaces of pouch walls.
  • two sets of inner profiles are disposed on pouch walls wherein each set includes a male and a female closure element.
  • the profiles are engaged with each other by applying closing forces against the outer surface of the pouch walls, typically by sliding a users thumb and forefinger along the entire length of the clsoure device, while simultaneously applying the forces. While the closure of the seal is elegant and straightforward, problems often arise when the user comes to re-open the closed pouch. Generally speaking, opening the closed pouch is difficult and cumbersome to achieve.
  • a number of zipper systems have been designed to permit opening and closing of the seal.
  • Ausnit in U.S. Pat. No. 4,787,880 discloses a bag which has two zipper strip bases secured to opposing wall panels of the bag.
  • the bases each includes at least two arrow-shaped profiles extending therefrom to engage with the profiles of the opposing base, wherein the profiles of the same base are adjacent one another.
  • Malin in U.S. Pat. No. 6,167,597 discloses a zipper strip for a reclosabie package, wherein the zipper strip includes a male and a female profile.
  • One or both of the profiles includes at least one high compression member that extends from a base thereof to touch a base of the opposite profile to allow the profiles to be sealed without crushing or distorting the interlocking members.
  • First and second closure mechanisms are disposed on the internal sides of the first and second bag walls, wherein the closure mechanisms are parallel and spaced between about D.1 inch (2.54 mm) and 0.3 inch (7.62 mm) apart.
  • the first closure mechanism may have a first closure characteristic and the second closure mechanism may have a second closure characteristic different than the first closure characteristic
  • Pawloski et al. in US patent No. 7,850,368 disclose a reclosable pouch comprises a body portion having first and second pouch walls.
  • a first closure mechanism is disposed on internal sides of the first and second walls.
  • the first closure mechanism includes a first female profile having first and second spaced legs and a first male profile.
  • a second closure mechanism is disposed on the internal sides of the first and second pouch wails.
  • the second closure mechanism includes a second female profile having third and fourth spaced legs and a second male profile.
  • One of the first, second, third, or fourth spaced legs is longer than the other leg of the same female profrfe.
  • the first and second closure mechanisms comprise differing opening and closing characteristics.
  • Gzybowski in US patent No. 7,029,178 discloses one-way, zip-locking closure for bag-type containers that include slider zipper arrangements.
  • the locking mechanism includes a series of registration structures that is provided along one side of the mouth of the containers and a catch mechanism that is provided within the slider.
  • the catch mechanism engages the series of registration structures as the slider is moved to close the mouth of the container, and thereby prevents movement of the slider in the opposite direction.
  • Fratti et al. in US patent No. 8,262,289 disclose a reversible fastener is provided for a resealable bag-type container having first and second opposing wall panels, each of the first and second opposing wall panels having an interior face and an exterior face.
  • the fastener includes first and second closure mechanisms,
  • the first closure mechanism includes first and second complementary interlockable components disposed on the interior face of each of the first and second opposing wall panels proximate a top periphery of the first and second opposing wall panels.
  • the second closure mechanism includes first and second complementary interlockable components disposed on the exterior face of each of the first and second opposing wall panels proximate a top periphery of the first and second opposing wall panels.
  • plastic bags are provided either on a roll and typically reieasabiy secured to one another in an end-to-end configuration with prepunched scored lines as found in fresh vegetable and fruit departments of food stores/markets, or simply separately from one another.
  • an opening apparatus for use with a plastic pouch being reclosable or not, where the apparatus allows for a quick and easy opening of the pouch.
  • the present overcomes many of these problems, and provides a unique and advantageous design for a novel non-slip opening apparatus for a reclosable pouch or bag similar to the ZiplockTM designs currently on the market.
