Abstract: Disclosed is a frame for glasses with a front-piece, two temples connected each to the front-piece by a hinge which allows the rotation of the temples from a working position which is substantially perpendicular to the front-piece, when wearing the glasses, up to a rest position which is substantially parallel to the front-piece, when putting the glasses away. The front-piece includes two rims for supporting the lenses, and possibly a bridge connecting the rims. A pivot allows one of the temples or overturning temple and the relative hinge to rotate about an overturning axis substantially parallel to the front-piece. The overturning axis has a set inclination with respect to a straight line passing through the two centers of the rims, the inclination having a value that ranges from 2.5° to 25° and preferably from 5° to 25°.

Abstract: A glasses frame includes a front-frame and two temples (4, 5) connected to the front-frame through hinges which allow the rotation of the temples (4, 5) from a work position substantially perpendicular to the front-frame, to wear the glasses, as far as a home position substantially parallel to the front-frame, to put away the glasses. The front-frame includes two rims (2, 3) for lens support and possibly a bridge (1) connecting the rims and at least a pivoting element (C) apt to allow the mutual rotation by at least 180° of the rims (2, 3) around a rotation axis (X-X) substantially lying in a plane containing the two centers of the rims (2, 3) and perpendicular to the rims. The temples (4, 5) are directly hinged onto the rims (2, 3).

Abstract: Preform, made of plastic material for the manufacturing of hollow bodies through a blow-molding process, in which said preform comprises a substantially cylindrical body (1) having an open end (2) and a closed end {4), in which said closed end (4) has an outer surface with a varying curvature which is entirely enveloped within a hemispherical surface having a radius equal to the outer radius (R) of the cylindrical body (1) of the preform, said outer surface with varying curvature being tangent to the hemispherical surface in which it is enveloped in correspondence of the circular crown C and of the preform vertex.

Abstract: A preform (1) of plastic material for manufacturing bottles through a blow-moulding process includes a substantially cylindrical central body (3) having an open end (2) and a closed end (4). In correspondence of the central area of the closed end (4) there is provided a hollow appendix (5), projecting outwards of the preform, capable of internally housing the tip end of a stretching rod of the preform (1). Both the hollow appendix (5) and the remaining side portion of the closed end (4) of the preform may be spherical, conical, elliptical or parabolic.

Abstract: A disposable bottle (1) having a gradually collapsible structure, of the type in which the sidewalls (2) of the bottle have an accordion-like structure comprising several adjacent folds. Each fold is formed by two opposed surfaces (7, 8) of different width, comprising blocking means to prevent the recovery of the fold, under a predetermined force, once the same fold has collapsed for the first time.

Abstract: A multiple socket comprises a plurality of individual electric outlets (S, I) which are housed in a support (1) provided with a cable (C) and plug (P) for supplying electric power to said outlets (S, I). Said support (1) consists of several elements (2) which are hinged on the same axis (a), each element (2) being freely rotatable with respect to the adjacent elements (2). Each of said elements (2) houses at least one, preferably two opposite, and up to four of said individual electric outlets (S, I).
