Abstract: The present invention includes a system of multipart devices for the formation, pressing, and coating of molded pulp fiber articles. The system includes a mold device, a pressing device, and/or a coating device. Each device comprises a screen fastened or otherwise connected to the housing unit. The housing unit is a solid, non-porous housing element, and multiple housing units are configured to be reversibly connected to form a single device. When joined together, the screens of each housing unit form a continuous cavity for the molding, pressing, and coating of the product. The housing unit of a mold device comprises one or more vacuum systems which direct vacuum pressure to the product surface of the mold screen to form a pulp fiber product from a pulp fiber slurry. The pulp product is operable to be dried in the mold device, resulting in the formation of a stable, thin-walled pulp product.

Abstract: The present invention is directed to methods and systems for manufacturing molded fiber products using a pulp slurry and apparatus submerged in pulp slurry. The system utilizes a vacuum and mesh shaping of the product to pull fiber from the pulp slurry to the mesh shape while sucking the water through the mesh shape. The molded fiber product is then pressed to bolster the strength and structure of the product. The product is then coated using centripetal force to uniformly spread the coating across the selected area of the product. After coating, the product is pressed again to ensure the waterproof and airproof structure of the product. The materials used in manufacturing the molded fiber product are biodegradable, and the apparatus to form the molded fiber product is shaped according to the desired shape and size of the product.

Abstract: In a method for the production of coated substrates, a flowable, biologically degradable first coating which enhances gas tightness is applied to a cellulose-containing substrate. To obtain a packaging consisting only of natural components and offering good tightness, a second watertight coating made of animal and/or vegetable waxes and/or lipids is applied to the first coating.

Abstract: The invention relates to a receptacle (1) with a container (2) of fiber material having at least one opening (7) and a base (3) and a cover (10) for the opening (7), wherein the container (2) has a biodegradable coating. The invention further relates to a method for manufacturing the receptacle (1). The underlying problem of the invention is to provide a receptacle (1) which is formed exclusively from biodegradable components, which has a high gas-impermeability and a high mechanical stability and the manufacture of which is particularly flexible and cost-effective. To solve the problem, the container (2) has a biodegradable, cured impregnation which at least locally reinforces the structure of the container (2).

Abstract: The invention relates to a molded product made of fiber material with a connection element (11??). In order to achieve a particularly firm anchoring of the connection element (11??) in the fiber material of the molded product, the connection element (11??) has a connecting wall (17) with holes (18) through which the fiber material of the molded product projects.

Abstract: A packaging element for accommodating at least one product includes a blank which has a number of portions connected to one another by folding lines. The portions include an accommodating portion having at least one receptacle, the shape of which is matched to the shape of a product to be accommodated, a first side-wall portion, a first cover-wall portion, a second side-wall portion, and a second cover-wall portion. The first cover-wall portion may have at least one hollow, and the second cover-wall portion may have at least one protrusion with a shape and position complementary to the hollow.

Abstract: A packaging container having a top side, a bottom side extending parallel to the top side, and at least one side wall extending between the top side and the bottom side. The top side can have at least one protrusion, and the opposite side extending parallel can have at least one recess, into which a protrusion of a packaging container, for example, an identically shaped packing container, can be inserted. Such a packaging container can be produced in an economical and environmentally friendly manner, for example, by having holes punched in the top side and in the bottom side, and the protrusions and recesses attached in inserts, which are inserted into the packaging container.
