Definitions

  • the invention relates to a tubular bag pack for lumpy packaged goods with a sleeve, which is formed from a flat, foldable packaging material, of which two strip-shaped edge zones on their inner sides are connected to one another in a connection area by a seal, preferably by a peelable cold seal, in one of these Edge zones a connection-free with a U-shaped punching is provided, which is directed with its legs against the connection area and which forms the beginning of a strip-shaped tear-open area.
  • a tubular bag pack of this type is known from EP-A-399420.
  • a connection-free area is provided in each of the two edge zones, both of which are arranged one above the other, while the U-shaped punching coincides with part of the delimitation of these areas.
  • a disadvantage here is that even if the two strip-shaped edge zones run slightly against one another during the manufacturing process, the U-shaped punching falls into the connection area and the opening is thereby made more difficult. Furthermore, the tear tab, the beginning of which is limited by the U-shaped punching, is not easy to handle.
  • tubular bag pack according to the invention of the type mentioned at the beginning, which is characterized in that the U-shaped punching is provided within the connection-free area and does not adjoin the connection area at its U-base, that the strip-shaped edge zone, the has the U-shaped punching, with an area which comprises the largest part of this punching, protrudes beyond the free edge of the other edge zone, and that at this edge zone an area which from this punching is covered on three sides, is folded outwards onto the surface of the pack.
  • Claims 2 to 5 relate to advantageous refinements of the invention.
  • this packaging material consists of a 0.015 to 0.20 mm thick biaxially stretched polypropylene film (OPP film), a 0.007 to 0.009 mm thick, printed aluminum film, a paper with a grammage of 30 to 100 g / m 2 and a latex-based cold adhesive coating applied in the profile (2 to 7 g / m 2 solid).
  • OPP film gives the composite mechanical strength
  • the paper forms the carrier layer of the composite material and the aluminum foil the layer that ensures the gas tightness of the composite.
  • a U-shaped punching is now attached to the packaging machine - for each package to be produced - on one of the edges of the packaging material web pulled off the roll, the legs of which are directed towards the center of the packaging material web.
  • the web of packaging material is folded around the continuously supplied packaged goods, for example waffles, its edges are sealed to one another within a strip-shaped connecting area, and the two are sealed to one another
  • Edge zones which are referred to as "fins" are turned over onto the packaging surface in such a way that the edge zone containing the U-shaped punching comes to lie on the outside.
  • the packaging material tube enclosing the packaged goods is now each provided with two transverse sealing seams running parallel to one another between two successive packaged goods and divided into individual tubular bag packs by separating cuts between these two transverse sealing seams. These transverse seals then form the "fins" of the tubular pouch that protrude from the packaging envelope.
  • connection area 1 now schematically shows a perspective view of a tubular bag pack for waffles produced in this way.
  • the edge zone 2 coming to the outside is wider than the edge zone 3, so that between the edge 4 and the connection area 1 in the edge zone 2 there remains a connection-free area 5 which extends beyond the edge zone 3 located below.
  • the U-shaped punching 6 is provided, which extends with the ends 7 of its legs into the connection area 1.
  • punchings 6 can either already be present in the delivered packaging material web or can be punched into the packaging machine shortly before the packaging material tube is formed.
  • the packaging material forms a grip tab 8 within the U-shaped punching 6, which forms the beginning of a "virtual" strip-shaped tear-open area 9 with boundary lines 10 parallel to one another.
  • the grip tab is pulled in the direction of the arrow 11, the packaging material being selected at the ends 7 of the U-shaped punching tears approximately along the imaginary lines 10.
  • Fig. 2 shows the tubular bag package in a top view in a partial view, the package cover being partially broken open at the location of the U-shaped punching.
  • the cold adhesive is applied to the edge zone 2 in a mitigate coating in the form of a cross line grid, which increases the peelability of the cold seal in this sub-area 13 than in the remaining area 14 of the connecting area 1. This makes it easier to pull off the tear-open area during the opening process.
  • an area of the packaging material, which is covered by this punching on three sides, is folded over by 180 ° to the side of the packaging material which is coming to the surface of the pack .
  • This folding is particularly stable if the multilayer packaging material used contains an aluminum foil.
  • Multi-layer packaging materials that tear along longitudinal lines in the tubular bag package according to the invention during the opening process are described in the published international patent application WO 91/06488.
  • the tubular bag pack according to the invention is primarily used as a pack for foods such as chocolates or baked goods.
