The invention relates to a method for producing biodegradable, recessed moulded receptacle bodies (18) by baking an especially cellulose fibre-based baking material. According to this method, the baking material is simultaneously baked into several moulded receptacle bodies (18) between an upper and a lower baking mould in one baking operation. The baking material is baked into a flat body (12) between the two baking moulds, this flat body containing the moulded receptacle bodies (18) integrally and having a continuous closed surface. The moulded receptacle bodies (18) are then separated from the flat body (12). The advantages of producing flat bodies (12) of this kind lie in the handling during the removal of the flat bodies (12) from the baking moulds and during the subsequent surface-coating of the flat bodies (12).

La présente invention concerne un procédé permettant la réalisation de corps moulés de réception (18) creux biodégradables, par cuisson d'une matière à cuire basée en particulier sur les fibres cellulosiques. Selon ce procédé, la matière à cuire est cuite entre un moule de cuisson supérieur et un moule de cuisson inférieur durant un processus de cuisson pour obtenir en même temps plusieurs corps moulés de réception (18). Selon l'invention, la matière à cuire est cuite entre les deux moules de cuisson pour obtenir un corps plat (12) formant une surface continue, contenant l'intégralité des corps moulés de réception (18), lesdits corps moulés de réception (18) étant finalement séparés du corps plat (12). La réalisation de corps plats (12) de ce type présente des avantages de manipulation lors de l'extraction des corps plats (12) des moules de cuisson et lors d'un revêtement de surface final des corps plats (12).
