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.
Claims16
A process for sequentially forming a plurality of enclosed tetrahedral 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, wherein the open containers are tetrahedral containers, albeit with one face missing;
- wherein the edge which is folded alternates from one container to the next;
- 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 tetrahedral containers comprising the product.
An apparatus for sequentially forming a plurality of enclosed tetrahedral 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 means for folding the web 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 a means for sealing an edge arranged to seal the two edge portions together, thereby to sequentially form open containers, wherein the open containers are tetrahedral containers, albeit with one face missing, the apparatus further comprising a means for depositing product and a means for sealing open container, operable to sequentially form enclosed tetrahedral containers comprising the product from the open containers.
