摘要:
The present invention relates to a blowing device (1) for blowing gas through a gas-permeable tubular-shaped packaging material (29). The blowing device comprises at least one gas nozzle (19; 75, 77), adapted to blow gas from an outside of the tubular-shaped packaging material through the tubular-shaped packaging material, and a guiding member (3), which comprises a web passage (5) having a surface (7) adapted to face the tubular-shaped packaging material, such that the web passage surrounds or substantially surrounds the tubular-shaped packaging material. The present invention further relates to a use of the blowing device, to a sealing arrangement (27, 71) for transversely sealing a gas-permeable tubular-shaped packaging material (29) and to an arrangement (37) for manufacturing of pouched products (39), which arrangement comprises such a sealing arrangement. The present invention also relates to a method for transversely sealing a gas-permeable tubular-shaped packaging material and to a method for manufacturing a pouched product, e.g. a portion-packed pouched oral snuff product.

A package (1) including: a container (200); and a plug seal closure (310) operatively engaged with an open end (230) of the container; wherein the container has; a closed end (220) opposing the open end; a container wall (270) extending longitudinally between the closed end and the open end about a longitudinal axis (L); an end seam (295) extending at least partially across the closed end; and a longitudinal overlapping seam (300) extending from the end seam, a portion of the overlapping seam extending longitudinally along the container wall between the closed end and the open end; wherein the open end is narrower than at least a portion of the container away from the open end of the container; and wherein the closed end and the container wall consist of a one-piece thermoplastic substrate (210).
摘要:
Two components (32, 34), that may be thermoplastic composite components, are joined together by a thermoplastic film (36) forming a thermoplastic joint (31) between the components (32, 34). The thermoplastic film (36) is preferably amorphous and it preferably fuses during the formation of the join (31).
摘要:

摘要:
The method and apparatus are applicable in production of cans, bottles and more. It has enhanced weld quality, improved appearance and low waste. Laminated foil 2 moves with relatively constant speed and is formed around the mandrel 1. Over the foil edge 7 is placed compressing/cooling bar 10 having cooling channel 11, and over second edge 8 - compressing/cooling bar 12 having cooling channel 13. The profile of mandrel 1 in the heating area of overlapped edges 7 and 8 of foil 2 has step 5 to form cavity 6 between edges 7 and 8. The heating unit 3 is a nozzle supplying hot air into cavity 6. Melting of the foil 2 is limited only to the area, which is not in contact with compressing/cooling bars 10 and 12 and the mandrel 1. During further movement of foil 2 due to change in profile of mandrel 1, transforming into plane 9 the end 8 is lifted up while pressed the end 7 and the two together in compressing/cooling bar 10. After welding area there is cutter 4 to cut the tube into tubular bodies.?
