Abstract

Improved case, which has no hinge or hinge, essentially characterized, being constituted by two equal frames (1), formed by three arms of triangular section, which have the internal vertex (2) flattened, to increase the contact surface of closure, whose opposite triangular face, (18) is the concave outer face attached to the single sheet (5), which forms the outer and inner part of both covers with the frames (1), suitably spaced at their ends, to form the spine (3) of the case, with the addition of two internal folds (4), for ease of closing the case; for presenting the central arm of the frame (1), with internal bulge (6) in its middle, provided with a cavity (9), in which a prism (10) is housed, in u, which has an axis (8), which protrudes from a hole (7), to promote the opening of the case; by presenting a flexible sheet (11), housed in a slot (1.2), of the cavity (9), whose sheet acts as a spring, supporting the prism (10) and yields by finger pressing the shaft (8); for presenting the frame that constitutes the bottom of the case, an axis (13,), provided with a suitable notch (14), that when introducing the shaft (13,), in the hole (16) of the respective bulge (6), it enters the hole (17), engaging the notch (14), with the wall of the prism (1.0), pressed outwards by the action of the spring sheet (11), closing the case; because the axis (1, 3) is attached to a prism (15), housed in the respective cavity (9), of the bottom frame.
