a shell formed by at least a first shell portion and at least a second shell portion distinct from each other and adapted for being assembled together, the first shell portion including a first peripheral rim edge, the second shell portion including a second peripheral rim edge, and the first peripheral rim edge and the second peripheral rim edge include, respectively, a first joining rim portion and a second joining rim portion adapted to be coupled to each other to fix the first shell portion with the second shell portion, wherein:
the first joining rim portion includes at least a joining channel including a bottom surface and a plurality of side surfaces, the joining channel being adapted to cooperate with a corresponding at least a joining projection including a concentration head and a body, the joining projection being included in the second joining rim portion,
the bottom surface is adapted to cooperate with the concentration head and the plurality of side surfaces are adapted to cooperate with the body,
the body has a section having two surfaces that are complementary in shape to two of the side surfaces of the joining channel,
the joining channel and the corresponding joining projection are fixable to each other by heat welding the concentration head of the joining projection includes a vertex adapted to cooperate with the bottom surface of the joining channel, the vertex being spaced from the two surfaces of the section of the body, and
the vertex has an internal angle in a range of 45 to 120 degrees.
