1. A collapsible container (1) for liquids and the like, comprising: two deformable membranes (2) placed side by side along an intermediate plane (2a), said deformable membranes (2) comprising: a plurality of mutually bound edges (3) able to define a housing volume for liquids and,an aperture (4) made of two mutually unbound edges and able to make an inlet for said liquids, said deformable membranes (2) defining: a rest configuration in which said two deformable membranes (2) are close to the mutual contact along said intermediate plane (2a), anda working configuration in which said two deformable membranes (2) are elastically deformed and form an arrow in a direction of mutual removal, by defining a containment volume for liquids and the like, and wherein said membranes (2) define in a view perpendicular to said intermediate plane (2) and parallel to said aperture (4) and in said rest configuration, two convex segments of which said convexity being facilitated by a step (3a) present at said edges (3), and wherein said step (3a) has a shape of an arrow, both in a rest and working configuration, defined by a portions of said two membranes (2) adjacent to said welded edges (3), and wherein said collapsible container (1) comprises: a groove at the center of said collapsible container (1), at said aperture (4), able to further increase the concavity of said deformable membranes (2) and to form a folding line for a working configuration; and wherein said deformable membranes (2) have a shape tapering from said aperture (4) to an opposed end (5), and in which said aperture (4) is opposed to a top edge (3) which defines a bottom of said collapsible container (1), said container (1) having along said intermediate plane (2a) a triangular shape with an edge (3) made of a curved top, so as to connect the two oblique sides of said triangular shape; and wherein said a working configuration is attained when a user holds with one hand said container (1) at its edges (3), and said hand is exerting a deformation movement, substantially parallel to said intermediate plane (2a) and to said aperture (4), using elastic deformation of said membranes (2) to achieve said working configuration of said container (1); and wherein said rest configuration is attained when a user stops exerting a deforming force, so that said membranes (2) are free to release a stored energy of said elastic deformation, by returning consequently said container 1 in a rest configuration; and wherein said two convex segments have a mutual maximum separation comprised between 1 and 3 mm. to allow the collapsible container to contain a liquid even in a rest configuration and facilitate the moving in opposite directions of said convex segments when both edges (3) are squeezed using only one hand. 2. The collapsible container (1) according to claim 1, wherein said aperture (4) is formed by a linear segment and made of two mutually unbound edges and able to form an inlet for said liquids. 3. The collapsible container (1) according to claim 1, substantially without a bottom or support base to an outer surface. 4. The collapsible container (1) according to claim 1, further comprising, at said aperture (4), handles for inserting a collar or a similar support. 5. The collapsible container (1) according to claim 1, wherein said membranes (2) are made of a polymeric, thermoplastic material. 6. The collapsible container (1) according to claim 1, wherein said membranes (2) are mutually bound by thermal welding.
