ABSTRACT:
An article holder characterizd by a unitary construction forming a living hinge structure provided by integral sheet portions and sections coupled together across hinge lines to provide ease of mounting an article on and removing the article from the holder and to permit significant reduction in the number of the component members and elements and accordingly the production cost of the article holder. Such an article holder comprises comprising a base section hingedly connected to the bracket portion, a flap section hingedly connected to the base section across split first hinge lines which extend laterally of the unitary member, an intermediate joint section intervening between the base section and flap section and having a portion extending into the base section and a portion extending into the flap section, the joint section being defined by a second hinge line intervening between the base and joint sections, a third hinge line intervening between the flap and joint sections, and a pair of cut lines extending between the second and third hinge lines. The split first hinge lines are aligned with each other across the intermediate joint section and the second and third hinge lines extend in parallel with the first hinge lines. A generally cylindrical spool portion axially extends from one side face of the flap section for engagement with the article to be supported by the holder.
