Product made using a mass comprising natural polymers, wherein the product comprises at least a first and a second product part, connected by a hinge construction, wherein the hinge construction comprises at least one flexible sheet element and one bridge portion made of said mass comprising natural polymers, wherein the hinge construction is designed such that, prior to a first time hinging, the at least one bridge portion forms a more rigid connection between the first and second product part than the flexible sheet element and by hinging said bridge portion is severed, such that the first and second part are substantially only connected by the or each flexible strip.
A product made using a mass comprising natural polymers, wherein the product comprises at least a first and a second product part, connected by a hinge construction, wherein the hinge construction comprises at least one flexible sheet element and one bridge portion made of said mass comprising natural polymers, wherein the hinge construction is designed such that, prior to a first time hinging, the at least one bridge portion forms a more rigid connection between the first and second product part than the flexible sheet element and by hinging said bridge portion is severed, such that the first and second part are substantially only connected by the or each flexible sheet element.
A method for manufacturing products, wherein a mass comprising at least natural polymers, such as starch, is introduced into a mold and the mass in the mold is heated, such that it involves at least cross linking of the natural polymers, where the mold comprises at least two product part forming parts, connected by a bridging portion, wherein at least one flexible sheet element is placed in and/or on said bridging portion, preferably prior to introducing said mass into said mold, said at least one flexible sheet element extending at least partly into the product forming parts on either side of the bridging portion and is connected to the mass introduced into the mold, wherein during introduction of the mass into the mold at least part of the mass flows over the bridging portion, over and/or alongside said at least one flexible sheet element, forming at least one bridge portion in the product to be formed, connecting the product parts formed in said product part forming parts, wherein preferably the mass covers at least part of at least one surface of the flexible sheet element.
An apparatus for forming a product from a mass comprising at least natural polymers, such as starch, comprising a mold, where the mold comprises at least two product part forming parts, connected by a bridging portion, wherein the apparatus comprises a system for placing at least one flexible sheet element in and/or on said bridging portion, preferably prior to introducing said mass into said mold, said at least one flexible sheet element extending at least partly into the product forming parts on either side of the bridging portion, to be connected to the mass introduced into the mold, preferably such that the mass covers at least part of at least one surface of the flexible sheet element, connecting the product parts formed in said product part forming parts.
