Abstract:
The present invention relates to a container, particularly a cup, with a base and a first sidewall, whereas the first-sidewall comprises at least a first, at least partially circumferential shaping directed inwardly and/or outwardly.
Abstract:
The present invention relates to a process for the production of a cup having a bottom and a sidewall attached to the bottom, wherein the sidewall preferably comprises a rolled rimat its upper edge opposite to the bottom, wherein the sidewall comprises a single layer or a plurality of layers, wherein at least one of the layers is produced from a paper material, carton, plastic, PLA, a renewable and/or a biodegradable resource and or any other comparable material, wherein at least one shaping is shaped into at least one of the layers of the sidewall, wherein the shaping is at least partially ring-shaped, wherein the shaping extends at least partially over the perimeter of the sidewall, wherein the shaping is inwardly or outwardly directed, wherein the shapings are compressed in height such that an edge of each shaping touches an opposite segment of the shaping and/or that both edges of each shaping touch each other and are joined together, and a cup produced by this process.
Abstract:
The invention relates to a packaging (20) that can be designed as a paper cup (20) and to the production thereof. The packaging (20) comprises an outer surface made of composite material and having two side edges (15, 16), which are adhesively bonded to each other so as to overlap in a connection area. An outer layer of the outer surface is made from the material of a first web (11), which is coated with a second web on the side facing inward. Said second web (13) is formed into a tab (17) in the area of one of the side edges (16), said tab being laid around the side edge (16) as an edge protection. In the connection area, the following layer sequence results from the inside to the outside: second web (13), material of the first web (11), tab (17) made of the material of the second web (13), second web (13), and material of the first web (11).
Abstract:
The present invention relates to a multilayered packaging material, preferably with moisture-, aquous liquid- and/or grease-proved properties, comprising at least one substrate layer (4) and at least one barrier layer (5, 15) with such barrier properties for at least a defined period of time, wherein the substrate layer (4) is based on paper, paperboard, nonwoven fabric, moulded fibre or other material, in particular composed of renewable and/or preferably biodegradable raw materials, and at least a single- or multi-layer barrier layer (5, 15) in particular of renewable and/or preferably biodegradable raw materials and packagings preferably made thereof.
Abstract:
A method and an apparatus for manufacturing conical paperboard cups from a curvilinear side wall blank (16) and a circular bottom blank which are of polymer-coated paperboard. At least one of two side seam areas (17, 19) of the side wall blank (16) is heated with a laser beam (40) which is guided to move over the side seam area (17) as the blank (16) remains stationary, after which the side seam areas (17, 19) are laid on top of each other and pressed together for forming the side seam of the cup. The bottom seam of the cup can be formed in the same manner by using the laser beam for heating the polymeric coating before pressing the seam areas together.
