Container for small objects, particularly pastilles and similar confectionery products

A container of the type having a hollow body having substantially the form of a right prism and including a rectangular base wall and two pairs of lateral walls of equal length which project from opposing sides of the base wall and define an entry opening into said body at their edges opposite the base wall, and a hollow, plastic closure element, the closure element including:

• a rectangular end surface of the closure element with dimensions corresponding substantially to the external perimeter of the edges of said lateral walls defining said entry opening;
• a skirt extending perpendicularly from said end and having, for a certain distance from said end, dimensions that it can be inserted into said hollow body and grip resiliently the internal surfaces of said lateral walls adjacent said entry opening in the assembled condition of a container, a rectangular aperture defined by said end and having a major axis coincident with the major axis of said end, said aperture being closable by a closure flap, said aperture extending from one of the minor sides of said flap for said aperture, said closure flap including a plate with flat parallel faces which is hingedly connected to said end of said aperture opposite said minor side about an axis parallel to the latter by an integral hinge constituted by a reduced section portion of the flap, said flap being of a length such that a terminal portion of its free end extends axially beyond said minor side and acts as a gripping tab when said flap is closed, and cooperating snap-engagement means formed on said terminal portion of said flap and on the minor wall of said skirt beneath the external end of said aperture, said snap-engagement means being of improved construction and comprising:
• a transverse projection heel formed parallel to said hinge axis, on the surface of the said projection facing towards the hinge of said closure flap, and a transverse groove having a section complementary to that of said heel and snap-engageable thereby formed in the external surface of said minor wall of the skirt, a frontal edge on side minor wall of the said front edge defining the top of said groove and said frontal edge having a central part which projects outwardly relative to its lateral parts;
• said lateral parts being set back slightly with respect to the external surface of said minor wall of the skirt, and being coplanar with the external surface of said minor wall;
• said closure flap having a smaller thickness than the end surface of said closure element, and two laterally-spaced, longitudinal ribs provided on a lower surface of said closure flap which extend from a zone of said flap spaced from said integral hinge to said heel;
• the length of said ribs being such that they extend from a zone spaced from said hinge.
