ABSTRACT:
A molded plastic snap hinge box comprises two halves (U, L) with a hinge (H) formed from parts integrally molded to the two halves. One half of the hinge consists of three balls (20, 24) in a row, all on ball support arms extending from the box. The middle ball is larger than the two side balls; the two side balls are of equal diameter. Two coaxial cylindrical spacers (30) are mounted on spacer support arms extending from the other box half. The cylinder ends are dished spherically with radii equal to the ball radii; the cylinders snap in between the balls to form the hinges. When the hinge is assembled the three balls are each centered on the cylindrical spacers' axis, which runs parallel to the rear edge of the box in the plane of the box opening rim. The box may be closed with a latch closure (C) comprising a plate (40) on either box half. The plates are each coplanar with the opening rim. Each plate has a hole (44) and a post (42), the post of one plate mating with the hole of the other. The posts are inclined from the plane of the plates so that they interfere slightly with the holes when entering. This latches the box. The plates are offset from each other to provide for unlatching by finger forces.
