  • Publication number: 20090255934
    Abstract: A method and apparatus prevents vacuum restraint during removal of a plastic trash bag liner from a trash container. The side wall of the trash container includes a vent port near the bottom of the container, and a flapper valve attached above the vent port on the inside of the container covers the port with a covering element while the trash bag rests. When the trash bag is filled and thereafter lifted out of the trash container, the covering element lifts to open the vent port and cause an inflow of air under the trash bag to prevent a vacuum forming.

  • Publication number: 20090194539
    Abstract: A vented trash receptacle that prevents a bag filled with refuse from becoming stuck therein by releasing the vacuum that can form as the bag is being pulled therefrom. The receptacle includes an open-topped container having a bottom wall with an opening and a side wall extending upwardly from the periphery of the bottom wall. A lid is removably positioned atop the side wall. A valve is secured to the bottom wall for closing the opening in the bottom wall. The valve has an anchor that is affixed to the bottom wall remote from the opening. The valve also has a float that is flexibly tethered to the anchor. The float normally rests upon the bottom wall above the opening so as to selectively prevent the flow of air and water through the opening. The float is buoyant in water.

  • Patent number: 7017761
    Abstract: A container comprises a substantially dimensionally stable outer wall and an easily deformable inner pouch which gradually contracts upon discharge of the contents of the container. As a result, pressure compensation is provided in the increasing space between the outer wall and the inner pouch. The outer wall and the inner pouch have, therebetween, a layer of a pressure compensating material that expands when acted upon by an agent.

  • Patent number: 6594876
    Abstract: A method and kit for modifying an existing trash can to minimize or to prevent the occurrence of a vacuum seal that may occur when a trash can liner is pulled out of the trash can. The method comprises making three holes substantially close to each other into a trash can wall near the opening of the trash can. Then threading one end of a conduit through one of the holes so that the first end of the conduit reaches deep within the inside of the trash can and the other end of the conduit extending through the hole and outside of the trash can. The two remaining holes are used to securely mount the conduit onto the inside surface of the trash can by threading a tie through these two holes and around the conduit. In modifying an existing trash can by this method, the vacuum seal that often is encountered experience when pulling the trash liner from a trash can is avoided because the conduit allows air to freely pass into the bottom of the trash can. The kit comprises a conduit, drill bit and a tie.

    Abstract: A process for the production of a container (1) comprising an outer container (2), an inner bag (3) disposed therein and a pressure equalization opening (10) disposed in the outer container (2), and also a container (1) produced according to this process, is described, wherein firstly a pre-molding, comprising two coaxial tubes, is first produced by co-extrusion with the help of a blow mold and with an outwardly-projecting base seam (5) being formed. The process is to form a pressure equalization opening (10) in the outer container (2) of the container (1) without endangering the integrity of the container (1), wherein a lower wastage rate and higher productivity are to be achieved. This is attained by a process wherein the base seam (5) is partially cut off and a force which acts in the direction of the seam is introduced into the pre-molding, which still has a temperature of 40° C. to 70° C.
