  • Publication number: 20210276763
    Abstract: The present invention relates to a PET bottle which increases recycling rate of PET bottles, wherein the PET bottle comprises a label that assembles the cap 20 without a retainer ring 21 on to the body 10 of the PET bottle, seals from the top of the cap 20 to the upper portion of the body 10 with the one continuous label and safety seal film 50, and has vertical parallel perforated lines 51 on one portion of the sealed label and safety seal film 50. A flap 52 extends from the end of the upper end of the perforated lines 51 to assist with tearing the label. The sealed label and safety seal film 50 covers the upper portion of the body 10 in shape of an inverted funnel, such that when it is torn along the perforated lines 51, the film 50 will be separated naturally from the bottle.

  • Patent number: 7455054
    Abstract: A canister for a motor vehicle is connected to a fuel tank and a throttle pipe to adsorb fuel gas containing noxious constituents, which are generated in a fuel tank. A first space and a second space, through which the fuel gas flows, are defined, the fuel gas flows in opposite directions through the respective first and second spaces, the second space is divided into space parts by a plurality of support filters, a fuel gas reducing device is installed in one space part, which is delimited by two support filters, and air flow through the fuel gas reducing device is perpendicular to air flow through the first and second spaces.

  • Patent number: 6942721
    Abstract: Disclosed is a canister for a motor vehicle. A liquid trap provided to an upper surface of a canister body is formed to have a circular configuration. A plurality of intake pipe nozzles are connected at an angle to a guide pipe which is installed through a center portion of the liquid trap, such that the intake pipe nozzles extending in a radial direction are separated one from another by a predetermined angle along a circumferential direction. A bottom wall of the liquid trap is formed such that an upper surface of the bottom wall is inclined downward from a center portion thereof toward an edge portion thereof. A diffusion device is disposed directly below the liquid trap to uniformly distribute evaporated gas to be introduced into the canister body.
