  • Publication number: 20040083681
    Abstract: Waste disposal device including a container defining a waste storage chamber and a cartridge arranged in the container and containing a length of flexible tubing for encapsulating waste packages. A retention mechanism is arranged in the container to hold the waste package. A rotation mechanism is provided to cause relative rotation between the cartridge and the retention mechanism in order to form a twist above a waste package when the waste package is being held by the retention mechanism and thereby encapsulate the waste package in the tubing. Encapsulation of the waste package prevents the release of odors from the waste package and thus, the invention provides a convenient and sanitary disposal of the waste packages. A series of encapsulated waste packages is thus created in the container, each package contained within a portion of the tubing and sealed at each end by the twisting process.

  • Publication number: 20040020175
    Abstract: Waste disposal device including a housing defining a waste compartment for receiving enclosed waste and arranged to removably receive a cartridge containing a length of flexible tubing which operatively receives waste therein, a retention mechanism for holding a quantity of waste received in the tubing and a rotation mechanism for rotating the retention mechanism when the quantity of waste is held thereby and while the cartridge is stationary in order to twist the tubing and enclose the held quantity of waste. The compartment in the housing receives the enclosed waste. The waste is thus rotated while the cartridge is held against rotation thereby enabling the formation of the twist above the waste to enclose or encapsulate the waste. A pushing mechanism may be provided on a cover of the device to push the waste into engagement with the retention mechanism.

  • Patent number: 6685199
    Abstract: A cart has a collapsible frame which is foldable into a closed position for forming a narrow lateral profile and unfoldable into an unfolded open position. The frame has two support members. Each support member has a pair of legs extending downwardly from its opposite ends and a side arm extending between two of the legs on each opposite lateral side of the frame for securing the frame in the unfolded open position with the support members spaced apart. The side arms have hinges for folding the arms relative to a support member. A foldable tray interconnects the legs of the frame for forming a platform adjacent the bottom of the cart. Upon folding of the cart, the tray folds and the cart collapses into the closed position with the support members drawn together into close proximity to each other.

  • Publication number: 20030222545
    Abstract: Modular storage and/or display system including substantially rectangular modules each including opposed first and second sides, opposed third and fourth sides perpendicular to the first and second sides and coupled thereto. A male connecting member is provided on an outer surface of each of the first and third sides and a female connecting member is provided on an outer surface of each of the second and fourth sides. The female connecting member has a structure complementary to the male connecting member. An additional male or female connecting member is provided on each of the first and second sides. By providing the same male and female connecting members on all sides of the modules, each module is connectable to any other module by coupling a connecting member on that module to an opposite connecting member on the other module.

  • Patent number: 6443481
    Abstract: A movable cart having a collapsible frame with the frame being foldable into a collapsed or closed position for forming a narrow lateral profile and into an unfolded open position adapted to support a removable storage container. The frame comprises support members with each support member having a pair of legs extending downwardly from its opposite ends and a side arm extending between two of the legs on each opposite lateral side of the frame for securing the frame in the unfolded open position with the support members physically spaced apart to support the removable storage container. The side arms have hinges for folding the arms about a common plane lying in substantial parallel alignment with each support member. The frame also has a tray interconnecting the legs of the frame for forming a level platform adjacent the bottom end of the cart.
