Abstract
To guard against injury to persons engaging the trim edges of a hinged container, a protective flap extends from the lid on either end of the axial hinge. The flaps extend from the corners of the lid adjacent respective trim edges of the hinge. The flaps have a rounded bottom portion which is extended past the axial hinge line. The curved structure of the protective flaps helps to gently deflect objects, such as fingers, away from any sharply angled trim edges of the hinge, thereby guarding handlers from accidental injury.
Claims13
A plastic thermoformed hinged container comprising:
- a thermoformed plastic sheet having a trim edge and comprising a lid and a base formed from a thermoformable plastic material;
- the thermoformed sheet including a hinge connection between adjoining edges of the lid and base for pivoting of the lid and base between open and closed positions;
- the lid and base in the closed position forming a generally rectangular perimeter of the closed container with the hinge connection forming one edge of the rectangular perimeter;
- the hinge connection comprising:
- a hinge line aligned along an axial hinge axis;
- abutting planar wall portions of the lid and base adjacent either side of the hinge line having upper planar wall surfaces lying in a common plane when the lid and base are in the open position, the upper planar wall surfaces being in mating planar engagement while the hinge line forms the one edge of the container perimeter when the lid and base are in the closed position;
- the hinge line and abutting planar wall portions having opposing first and second trim edges recessed inwardly from the rectangular perimeter;
- and
- first and second protective flaps extending from the lid and spaced from the first and second trim edges by first and second rounded trim edge inlets, respectively, the flaps forming hinge guards restricting access to the first and second trim edges of the hinge line, wherein each flap has a rounded trim edge perimeter that lies in the common plane and overlaps the hinge line.
