Patent ID: 8505933

Claim:
A roll container including: (a) a base having a front side and a rear side, with an imaginary vertical center plane running along the center of the base from the front side to the rear side; (b) a number of transport rollers mounted on an underside of the base; (c) a first side wall attached to the base at a first lateral side of the base and extending upwardly from an upper surface of the base, and a second side wall attached to the base at a second lateral side of the base and extending upwardly from the upper surface of the base, the first and second side walls each having a respective front vertical end strut and a respective rear vertical end strut with one or more horizontal support struts connecting the respective front vertical end strut and rear vertical end strut; (d) wherein at least one horizontal support strut of the first side wall is aligned in a horizontal plane with a respective horizontal support strut of the second side wall to produce a respective insert base support in which the respective horizontal support strut of the first side wall provides a first horizontal support surface located between an inside surface of the front vertical end strut of the first side wall and the vertical center plane, and in which the respective horizontal support strut of the second side wall provides a second horizontal support surface located between an inside surface of the front vertical end strut of the second side wall and the vertical center plane; (e) a respective indentation in each front vertical end strut for each horizontal support strut connected thereto, each respective indentation being located on an inner side of the respective front vertical end strut in an area immediately above the respective horizontal support strut and opposing a respective indentation located on an inner side of the other front vertical end strut; and (e) an insert base adapted to be received and supported on a respective insert base support in an inserted position in which both a front portion of the insert base and a rear portion of the insert base are supported on a respective upper surface of the respective insert base support, the insert base (i) having a width less than the distance between the front vertical end strut of the first side wall and the front vertical end strut of the second side wall at the level of the respective opposing indentations therein, and (ii) having a first lateral side located proximal to the first side wall when the insert base is in the inserted position and a second lateral side located proximal to the second side wall when the insert base is in the inserted position, and (iii) having one or more lateral support elements at each lateral side of the insert base, and (iv) wherein each lateral support element includes an elongated rib member that extends along a lateral surface of the horizontal support strut at that lateral side of the insert base when the insert base is in the inserted position.
