Abstract
An apparatus and related method are provided for converting an open-topped container into a top-emptying container. The apparatus preferably includes a cover having ground-engaging feet and a discharge opening able to be opened and closed. A coupling device is included on the cover for coupling the cover to the open-topped container. A cradle having an entry side and supports provides lateral and back support for a container-cover assembly when the cradle is inverted, in a controlled manner, by a rotationally inverting device. The cradle further includes openable end members with a spacing apart when closed, so that end movement of the container-cover assembly in the cradle, during inversion of the cradle, will be substantially eliminated.
Claims12
A method of converting an open topped container including a base and walls upstanding from the base into a top emptying container when the method includes the steps of providing a cover for the open top of the container wherein said cover includes a discharge means and ground engaging foot means, providing an inverter including a container receiving cradle which is mounted on a cradle support so said cradle can be rotationally inverted end over end and wherein said cradle includes a compartment accessible through a first side of said cradle and also includes spaced apart open ends each fitted with an openable closure member, and the further steps of mounting said cover over the open top of the container, securing the cover to the container to provide a container-cover assembly, positioning said cradle with one of said closure members closed to provide a support on which said base can be placed and with the other of said closure members at least partially open, loading said container-cover assembly into said compartment through said cradle first side and standing said base on said closed closure member, closing said other of said closure members to thereby restrain said container-cover assembly against longitudinal movement between the closed closure members during inversion of said container-cover assembly, rotationally inverting said cradle so said container-closure assembly is inverted and stands on said foot means on said other of said closure members, then at least partially opening said one of said closure members and removing said container-cover assembly from said cradle through said cradle first side.
An apparatus for converting an open-topped container into a top-emptying container, comprising:
- a cover with a discharge opening adapted to be opened and closed said cover being capable of being fastened to a container for covering an open end of the container;
- and,
- a container cradle able to be rotationally inverted end-over-end, said cradle including a container receiving compartment with means for minimizing movement of a container within said container receiving compartment during inversion of said container cradle, said means for minimizing movement within said container receiving compartment in an end-to-end direction includes two openable end closure members for said compartment with a distance between said closure members approximating, but being no less than, the overall height of a container when fitted with said cover.
A method for converting an open-topped container into a top-emptying container, comprising the steps of:
- providing a cover having discharge means and adapted for standing on a support surface;
- placing the cover over an open top of a container;
- securing the cover to the container for providing a container-cover assembly which, when inverted, is able to stand alone upon the cover;
- providing a cradle having an entry side, lateral supports and a back support opposite the entry side of the cradle, whereby the container-cover assembly is supported during inversion and has openable end members which, when closed, substantially prevent endwise movement of the container-cover assembly during inversion;
- providing means for inverting the cradle end-over-end in a controlled manner:
- loading the container-cover assembly into the cradle through the entry side of the cradle when one of said openable end members is open;
- closing the openable end member of said loading step;
- activating said means for inverting the cradle;
- opening one of said openable end members;
- and,
- removing the so inverted, stand alone, said container-cover assembly from the cradle.
An apparatus for converting an open-topped container into a top-emptying container, comprising:
- a cover having ground-engaging foot means and a discharge opening able to be opened and closed;
- coupling means on said cover for coupling said cover to an open-topped container;
- a cradle having an entry side and supports for providing lateral and back support for a container-cover assembly when sail cradle is inverted;
- and
- means for rotationally inverting said cradle in a controlled manner, said cradle further including openable end members with a spacing apart when closed, so that end movement of the container-cover assembly in said cradle, during inversion of said cradle, will be substantially eliminated.
