Abstract
Biodegradable, recessed molded receptacles (18) are produced by baking a baking composition between upper and lower baking molds (22, 24) in one baking operation to form a plurality of molded receptacles (18) in a coherent sheet structure (12) having an unbroken surface and containing the molded receptacles (18) which are subsequently separated from the sheet structure (12).
Claims11
A process for producing biodegradable, recessed molded receptacle, said process comprising the steps of:
- baking a baking composition between upper and lower baking molds to form, in one baking operation, a plurality of molded receptacles formed in a coherent sheet structure which has an unbroken surface and which contains the molded receptacles as an integral part;
- and
- separating said molded receptacles from said sheet structure.
A device for forming biodegradable recessed molded receptacles, said device comprising:
- two baking molds arranged one above the other for baking a sheet structure, said molds being transferable from a contact position in which they form between them a plurality of receptacle forming cavities which are closed to the outside and which rest flat against one another with contact surfaces facing one another, around the cavities, to a lifted-off position in which the baking molds are lifted from one another with the formation of a baking composition yield space between the contact surfaces.
