Abstract

DC60 (28/09/42) This invention concerns a packaging container (10) for pourable food products, consisting of layers of cylindrical packaging material with finned ends (11, 12), which is produced by sealing and cutting the continuous fibers of the packaging material of a continuous container. The path (14) of the perforation extends across one angle of the end (11) to facilitate the opening of the container. The cutting edge of the finned end (11) with respect to the path (14) of the perforation is aligned with the curve (11d), so that the first side (11b) of the cutting edge extends closer to the product filling (13) of the container than the second side (11c) of the cutting edge. The second side (11c) of the cutting edge, which is further from the product filling of the container than the first side, is shaped by the handle (11a) for opening the perforation angle. This invention also concerns knife devices and methods for manufacturing packaging containers. This invention concerns A pourable food product container (10) is made of layers of cylindrical packaging material with finned ends (11, 12) which is produced by sealing and cutting the continuous fibers of the packaging material of a continuous container. The path (14) of the perforation extends across one angle of the end (11) to facilitate the opening of the container.

Claims (20)

1. The packaging containers (10, 10', 10'', 10''') for pourable food products consist of cylindrical packaging material in layers with two fin-like ends (11, 12; 28, 35; 36, 37) which are produced by sealing and cutting the continuous packaging material fibers between successive containers at the perforation path (14) which extends across the corners of these ends (11; 28; 35; 36) to facilitate the opening of the containers. A special feature in the cutting edges of the fin ends (11; 28; 35; 36) with the perforation path (14) is aligned with the curve (11d), so the first side (11b) of the cutting edge extends closer to the product filling (13; 13'; 13''; 13''') of the container than the second side (11c) of the cutting edge, which is further away from the product filling. Product of the container on the first side from the handle bar (11a) for opening the corner perforated 2. The container under claim 1 has a special feature in the curved edge (11d) attached close to the path (14) of the perforation. 3. The containers under claim 1 or 2 have a special characteristic in the cutting edges of the other ends (12) which are arranged in a consistent curve. 4. The packaging containers described in any of Claims 1-3 have a distinctive feature: a Z-shaped cut edge. 5. The packaging containers under any of the claims 1-4 have a special characteristic in the curved cut edge (11d) consisting of indentations (16) in the perforation path (14) of the ends (11; 28; 35; 36). 6. The containers under any of the above claims have special characteristics as tetrahedral containers (10). 7. The containers under any of the claims 1-5 have special characteristics as parallel tube containers (10'). 8. The containers under any of the claims 1-5 are of special characteristics and are wedge-shaped (10'') containers. 9. The packaging containers under any of the claims 1-5 have special characteristics as non-folding pillow-shaped packaging containers (10'''). 10. The cutting device for cutting the sealing strips of packaging material between successive containers in a production splitting machine for packaging containers (10,10',10'',10''') for pourable food products has a special feature which represents the cutting edge, which consists of the first edge (17a) and the second edge (17b), which are side-displaced from the first edge (17a), and the second edges (17a, 17b) are connected by the path of the third edge (17c), which is extended at an angle between the two aforementioned edges. 11. The knife device under claim 10 has a special characteristic in which the angle between the first edge (17a) and the third edge (17c) is between 90° and 145°. 12. The knife device under claim 11 has a special characteristic, having an angle of approximately 120°. 13. The knife device under any of the claims of 10-12 has a special characteristic in the cutting edge, which consists of a fourth edge (17d) which extends in a lateral direction from the third edge (17c). 14. The knife device according to claim 13 has a special characteristic in which the angle between the first edge (17a) and the fourth edge (17c) is approximately 90° and 145°. 15. The knife device under any of the claims of Rights 10-14 has a special characteristic in that the blade edges are arranged in the same plane. 16. The knife device under any of the claims of 10-15 has a special characteristic in which the opposite (19) is provided for contact with the knife edge during the cutting operation, and the opposite is made of thermosetting plastic. 17. The knife device under claim 16 has a special characteristic: it is made of thermosetting polyethylene plastic. 18. Method of manufacture of packaging containers (10, 10', 10'', 10''') for pourable food products. These containers consist of layered cylindrical packaging material (21) with two transverse ends (11, 12; 28; 35; 36, 37), which are produced by sealing and cutting the packaging material continuously between successive containers at a path (14) of perforations that extend across the angle of one of the ends (11; 28, 35; 36) to facilitate the opening of the container. A special feature is the cutting of the packaging material between the two sealing pieces in the sealing area between the two containers, while producing the trailing edge of the preceding container and the front edge of the subsequent container at the corresponding attachment edge, which is aligned with the curve (11d). Thus, the first side (11b) of the cutting edge extends closer to the product filling of the container, and the second side (11c) of the cutting edge extends closer to the product filling. Product refills for other containers (10, 10', 10'', 10''') 19. The method according to claim 18 has a special feature. In the process of installing the wide end of the container, at the end corner there is a path (14) of perforations at the corner of the handle bar (11a). 20. The method under claim 18 or 19 has a special feature in the installation phase, the curve (11d) lateral to the fiber reference line seals, so that the end of the grip bar is close to the perforation (14).
