Abstract:
An envelope-type container (10) made from a dinked flat element (11), said flat element (11) having:(a) lines to facilitate folding (12) which identify a first side (23) of said envelope-type container (10);(b) three closing flaps (24) and an openable and closable flap (24') associated with said first side (23), said three closing flaps (24) being folded along said lines of facilitated folding (12) and connected to each other to form a second side of said envelope container (10) which is opposite to said first side (23) of said envelope container (10);(c) said closing flaps (24) and said openable and closeable flap (24') having weakening lines (25) substantially parallel to said lines of facilitated folding (12), said lines of weakening (25) being spaced apart from said lines of facilitated folding (12) to provide thickness to said envelope container; and(d) said envelope container (10) having an opening (16) which allows access to said envelope container (10), said opening (16) being openable and closeable by means of said openable and closable flap (24'), said openable and closable flap (24') having opening means which comprise an semi-circular shaped incision (17) on said openable and closeable flap (24') that forms an inwardly foldable element, said semi-circular shaped incision having ends (18) which prevent said semi-circular incision from extending to an edge (19) of said openable and closeable flap (24'), said semi-circular incision (17) having on a radius of a semi-circular surface at least one line of weakening (21) that facilitates the formation of said inwardly foldable element, said at least one line of weakening (21) being orthogonal to said edges (19) of said openable and closeable flap (24').
