Definitions

  • the invention relates to a film wrapping for objects, in particular goods packs, with an enveloping body which extends closed over a peripheral surface of the object and consists at least in sections of shrink film stretched in the circumferential direction.
  • Foil wrappings of the aforementioned type are known for ware packs of various types, in particular for cans, bottles or the like which are essentially cylindrical or have a cylindrical section, by widespread and thus obvious use.
  • the wrapping covers the closure or a prepared opening point of the goods package and thus also serves to protect the contents of the package, which is important for the consumer.
  • the wrapping that is necessary to open the goods package is designed because of the generally considerable tear and separation strength of the wrapping film, cumbersome and even difficult. It is therefore common practice to insert tear threads or tear tapes into the covering. This involves considerable effort in the mass production of such casings.
  • the object of the invention is therefore to provide a film wrapping which, with essentially undiminished cohesive strength, is distinguished by simple handling when opened and by low manufacturing outlay.
  • the solution to this problem according to the invention is determined in the case of a casing of the type mentioned at the outset by the fact that at least one film edge of the enveloping body A pair of pre-shaped, predetermined tear areas which engage in the edge area of the film edge and are limited in their engagement depth to this edge area and are arranged in the circumferential direction of the wrapped object at a mutual distance and which have a reduced tear and / or separation resistance in comparison to the adjacent film areas .
  • target tear areas of the aforementioned type which are limited in their extent to the edge of the film edge, offers the desired advantage of low manufacturing costs and, as detailed studies have shown, surprisingly enables a low effort without weakening the film across the width of the envelope manual, safe and complete separation process.
  • What is essential for this is the anisotropy generated by pre-stretching the film in the circumferential direction, which generally results in an increase in the tear propagation strength parallel to the direction of stretching, but a decrease in it transverse to the direction of stretching, ie in the direction of the intended crack propagation.
  • a suitable selection within the available film materials is necessary in order to exclude generally high values of tear strength.
  • polystyrene-based plastics are a particularly suitable material for the present film wrappings.
  • a further development of the task of the invention aims to use a film edge edge area, optionally provided with target tear areas of the type determined above, in order to achieve a functionally and aesthetically satisfactory design of the end face of goods packs.
  • the solution to this further task is based on a film wrapping for articles, in particular goods packs, with a wrapping body which extends closed over a circumferential surface of the article and preferably consists of shrink film which has been stretched in the circumferential direction, the wrapping body at least one at least along a circumferential edge has an end face of the encased object which extends around this peripheral edge and has at least one end face of the encased object which has a lower part with respect to the associated peripheral edge.
  • the task solution is determined by the fact that at least one of the end faces is provided with a disk-like cover element, the outer edge of which is held between the peripheral edge and the edge area of the film edge.
  • the cover element advantageously consists of transparent or translucent material.
  • the cover element can optionally also be provided with a desired three-dimensional shape and, for example, be concave or convex or can be designed in relief. In any case, there is the significant advantage that the insertion and mounting of the cover element does not cause any significant additional effort.
  • a sleeve-shaped packing body 1 is enclosed in an enveloping body 2 consisting of a shrink film and extending over the peripheral surface 4 of the packing body.
  • the film of the enveloping body is stretched in the circumferential direction of the packing body 1 according to arrow P.
  • Such a stretching direction results, for example, in the manufacture of the enveloping body from a film web stretched in its longitudinal direction, which extends in the circumferential direction of the wrapped object and is closed in a known manner, not shown here, in the axial direction by welding or gluing.
  • the enveloping body 2 encompasses the peripheral edges 1b of the end faces 1a of the packing body with film edge edge sections 6a on both sides.
  • the upper film edge edge section 6a visible in FIG. 1 is provided with two nominal tear areas 7 arranged in a small mutual circumferential distance in the form of elongated weak points, which emanate from the film edge 5a and at an angle - here essentially at right angles - to this radially in the Edge region 6a runs in and further around edge 1b, but is limited to the edge region 6aa directly adjoining this edge.
  • the target tearing areas consist of incisions, so that between them there results a handling section which lifts out of the film surface under the effect of the film tension and which can be comfortably gripped by hand.
  • a comparatively slight pull upwards or outwards and favored by the inherent tension of the film according to arrow P form 4 progressive tear lines R in the envelope within the unattenuated film areas on the circumferential surface, which experience shows that they maintain and close their axially parallel starting direction determined by the target cracking areas a complete separation of the envelope.
  • a lifting handling section is to be dispensed with, according to FIG. 3 it is advantageously possible to provide target marking areas 10 which are designed as notches and which maintain the cohesion of the film edge edge area 6a.
  • short gates 10a can be introduced on the film edge 5a without significant additional effort, to which notch groove sections 10b encompassing the edges are connected.
  • the film edge 5b lies with the adjacent edge area 6b of a cylindrical enveloping body 3 on the peripheral surface 4 of the same.
  • the inherent tension of the film when the target tear-off areas 9 are formed as incisions - as shown - generally leads to a striking lifting of the handling section H.
  • crack lines R. progressing axially parallel without continuous weak points in the envelope body.
  • the target tear areas 11 are designed as rows of perforations limited to the edge area 6b of the film edge, which in turn maintains the cohesion of the edge 5b of the film.
  • This allows the formation of a handling section H1 protruding from the peripheral surface 4 of the packing body 1 in the form of a rounded bulge in the edge area 6b of the film edge.
  • Such a film bulge can be produced in the production of the film web by a comparatively simple pressing process.
  • short gates 11a which do not significantly impair the cohesion of the film edge, can also be provided here, which facilitate scribing in the case of thicker films.
  • cylindrical enveloping bodies 3 are again provided, but with triangular cutouts 12 or 13 and sharp-edged inner edges 12a or 13a as the target marking areas.
  • This design offers certain manufacturing advantages and, in the case of the embodiment according to FIG. 6, to form a uniformly protruding handling section H2 of a pleasing outline shape.
  • a thread-like tear-open element 14 is formed, without any additional effort in the form of an already existing longitudinal weld seam of the enveloping body.
  • suitable seam bodies result for this purpose, on both sides of which the continuous tear lines R are formed without further precautions.
  • a protruding section 14a of the seam body which represents a comfortable handle for the formation of cracks, likewise results between the cutouts of the target scribe areas 13 without any special precautions.
  • FIG. 8 there is an opening on the end face 1a of the packing body 1 which is closed by an inserted cover D.
  • This cover forms a closing part 1c which is lower in relation to the associated peripheral edge 1b.
  • An enveloping body 2 in the manner of the embodiment according to FIG. 1 surrounds a circumferential edge of the packing body corresponding to a lower or upper edge area 6a or 6ab of the film edge. Between the upper peripheral edge 1b of the latter and the associated film edge edge region 6ab, the peripheral edge 15a of a disk-like cover element 15 is enclosed.
  • an additional product element Z for example a spoon, or an advertising medium or housed a giveaway.
  • Such a cover element can advantageously also be provided on package bodies with a closed and also with a flat end face design.
  • a spatially protruding, relief-like or dome-like design of the cover element - then again with the formation of a usable cavity - is particularly suitable.
