  • Patent number: 4215888
    Abstract: A pick-up device is disclosed which may consist of a rigid hollow sleeve having a bottom wall, a top wall and a pair of sidewalls. The sleeve is open at least at one end to receive a corresponding tray having a base wall and at least one, although preferably three generally upstanding sidewalls defining a substantially continuous rim. The tray is slidably arranged within the sleeve to be movable back and forth between an extended and retracted position. The tray, in its extended position, is placed rim-down over an object or material to be removed so as to cover the object. The tray is then pushed or retracted into the sleeve and thereby scrapes or carries the object into the sleeve for subsequent disposal. The sidewalls of the tray and sleeve may be foldable, if desired, to satisfy requirements for various uses to which the device may be put.
