Abstract
A process for sequentially forming a plurality of enclosed containers (32) comprising a product, the process involving passing a continuous web (10), comprising a strip of container material having two opposing edges (4, 6), to a folding station (12), whereupon each open container is sequentially formed by folding the web, to bring into contact two contiguous edge portions (9a, 9b) from only one edge of the web, then sealing the two edges together to form a portion of the web into an open container, depositing the product onto the web so that it is held within the open containers, and then sealing the open containers to form the enclosed containers.
Claims18
A process for sequentially forming a plurality of enclosed containers comprising a product, the process involving passing a continuous web, comprising a strip of container material having two opposing edges, to a folding station, whereupon each open container is sequentially formed by folding the web, to bring into contact two contiguous edge portions from only one edge of the web, then sealing the two edge portions together to form a portion of the web into an open container, depositing the product onto the web so that it is held within the open containers, and then sealing the open containers to form the enclosed containers.
An apparatus for sequentially forming a plurality of enclosed containers comprising a product, the apparatus comprising a folding station and a means for feeding a continuous web of container material having two opposing edges to the folding station, wherein the folding station comprises a folding means being arranged to form a respective open container by folding the web to bring together into contact two contiguous edge portions from only one edge of the web, the apparatus further comprising an edge sealing means arranged to seal the two edge portions together, thereby to sequentially form open containers, the apparatus further comprising a product deposition means and an open container sealing means, operable to sequentially form enclosed containers from the open containers.
A process according to clam 1, wherein the container material is flexible, preferably the material is so flexible that it can fold onto itself without requiring a pre-fold, at any point.
