• the peripheral areas (5) were made of standard steel for the lids of paint cans, steel which includes an internal coating, generally a varnish, and an external coating forming a decoration or an impression. These peripheral areas (5) were obtained by cutting and shaping, in particular by stamping, from material in strip or format.
• peripheral areas were produced in particular by taking standard steel covers of the state of the art and by cutting the surface S 'corresponding to the bowl.
• a series of covers (1) was made by cutting the same surface S 'from a whole series of covers of different shape and dimensions, and by assembling a same bowl (4), to obtain a whole series of covers (1) as illustrated in FIGS. 9d, 10a and 10b.
• peripheral pads (5) preferably multilayer materials comprising interior and / or exterior coatings sealable on PE, so as not to have to use a specific adhesive layer.
• the plug (6) forms a separate part, it is then produced separately and assembled by a simple axial snap-fitting, as it appears in FIGS. 7b, 11b and 12a, which is advantageous in terms of production cost .
• the inner edge (51) of the peripheral area (5) is introduced into the mold so as to form the bowl by overmolding of the inner edge (51).
• the bowl it is not necessary for the bowl to include an external projection (48) - a method not shown in a figure.
• the internal edge (51) has been heat-sealed by axial pressure with heating jaws on or under the external projection (48) of the bowl (4).
• the covers (1) according to the invention have very many advantages, because, on the one hand, they simultaneously solve many problems encountered by users of paints, by offering in particular for each container body (2) closed by these covers (1): - a bowl (4) forming a "retention tank" surrounding the orifice, so as to limit the risks of loss of paint and the risks of soiling, the two being typically linked,
• these covers also have advantages for the manufacturer and designer of covers and packaging for the conditioning of paint, namely:
• Manual gripping means 14 Vertical axis perpendicular to l2 15
• Joining means 60 Vertical positioning means of 6,600
