Plastic vessel comprising an accommodated metal element and method of producing the same

Plastic vessel comprising a metal element which is accommodated in its base, characterized in that:

• the plastic vessel comprises a vessel element and a cover such that the plastic vessel is formed in two pieces, wherein a recess is formed in the base of the vessel element, said recess being enclosed by the cover such that a central closed region of the recess is provided, which accommodates the metal element,
• wherein the vessel element and the cover are connected to one another thermoplastically under pressure by one of:
• thermoplastic shrinkage of the vessel element during cooling and curing thereof after the cover has been completely solidified, or
• thermoplastic shrinkage of the cover during cooling and curing thereof after the vessel element has been completely solidified,
• wherein the vessel element comprises a lower outer edge, which surrounds the recess and comprises an inner edge which is spaced apart from the outer edge and surrounds the central region,
• wherein a region of the recess is provided between the inner and the outer edge, which surrounds the central region, and wherein the cover comprises an arc which rises relative to a central region of the cover and surrounds the central region, and
• wherein the arc is formed corresponding to the recess such that, when the cover is arranged to provide the enclosed region the arc being disposed in the recess, and
• wherein the arc of the cover has an outer edge, which is the outer edge of the cover, and which corresponds to the outer edge of the vessel element and which is arranged adjacent thereto, and the arc of the cover has an inner edge which corresponds to the inner edge of the vessel element and which is arranged adjacent to said inner edge.
