Definitions

  • the invention relates to a pack for food or the like, which is hermetically sealed by means of an opening-side cover film, with a flag projecting radially outward beyond the package container edge and connected to the package container edge, which on its underside forms a cover film equipped with a tip. Piercing tool is formed.
  • Such a package equipped with a so-called opener is known from DE-PS 12 90 481.
  • the piercing tool is formed by a cut-away strip section of the container edge, the free end of which forms a tip on the underside in the form of a punch.
  • the strip section which extends freely along the edge of the container is to be lifted in order to carry out the perforation and pivoted over the perforable area of the cover film.
  • handling difficulties arise in that the punch comes out of its downward position; It takes considerable strength and skill to make the piercing.
  • the piercing plunger even assumes a position that is 90 ° to the piercing direction.
  • the corrective guiding of the strip section also means that the operator himself has to hold the pack more firmly in his hand. It is not uncommon for overpressure to occur, so that splashing of part of the contents cannot always be ruled out during punching.
  • the object of the invention is to avoid disadvantages of the type shown and a generic pack with cover film-through lancing tool so that the user is given a convenient tool that can even be used as a plug.
  • a generic pack for foods which can be opened comfortably and above all without the disadvantages described.
  • the cover sheet piercing tool remains an integral part of the packaging until it is used and is simply broken off from the edge of the container for use. It is held captive by a predetermined breaking point and is immediately recognized by the user as a means to be somehow associated with the removal of the contents, since it is designed in the form of a protruding, tangible flag.
  • the predetermined breaking point is directly adjacent to the cover sheet piercing tool. Accordingly, in addition to the actual function of serving as a tool, there is also the advantageous additional function of stiffening the surface of the flag, particularly in the area of the predetermined breaking point.
  • the flag can be broken off exactly.
  • the predetermined breaking point advantageously lies on the radial between the center of the container and that of the cover film piercing tool.
  • the piercing tool which has been completely detached from the container, can be used to close the pierced removal hole after the contents have been partially removed. This counteracts drying out, thickening or volatilization of the contents for some time.
  • a self-crusting perforation for example in the case of condensed milk as content, has been effectively countered.
  • the cover sheet piercing tool is arranged in the area-widened central section of the flag, the extended end of which is connected to the container edge by a second predetermined breaking point.
  • the area-widened central section of the flag enables the thumb to be conveniently attached as the link of the operating hand that applies the opening pressure.
  • the surface can go beyond the surface cross-section of the actual tool, which brings the simultaneous advantage of a splash guard if the internal pressure goes beyond what is assumed to be normal.
  • the predetermined breaking point is formed by a notch completely separating the cover film and partially severing the protruding container edge.
  • the cover film piercing tool Since the cover film is completely severed, detaching or breaking off the piercing tool in no way already results in the cover film being torn; rather, the hermetic seal is retained until the tool is placed in a willful manner. It is advantageous if the notch is approximately tangential to the circular container edge. This also makes it possible to incorporate part of the rim of the container into the material of the flag, which thereby becomes larger in area. Finally, it is also advantageous that the cover film piercing tool is designed as a hollow cone which is open at the top and which, together with the flag, is closed or overlaid by the cover film.
  • the hermetically sealable packaging for foodstuffs or the like shown in the drawing consists of a weakly conical cup-shaped container 1. Its wall 2 merges into a horizontally outwardly directed edge 3 at the top.
  • the container 1 is designed as a deep-drawn part made of plastic material.
  • the container opening is tightly covered by a cover film 4.
  • a cover film 4 As a rule, it is aluminum foil. This is sealed onto the edge of the container 3.
  • the production takes place in the following steps: deep drawing, filling, sealing, punching.
  • the container 1 When punching, the container 1 receives its final edge contour. It is released from the waste grid. If necessary, edge bridges can remain, so that there is always a pack group of several containers 1 as a so-called bar.
  • the pack container rim 3 continues into a similarly outwardly projecting flag F approximately the size of a fingertip. Its thickness corresponds to that of the edge 3.
  • the flag F is formed into a cover film piercing tool 6 equipped with a tip 5. It is a cone 7 that is deep-drawn at the same time. The tip 5 points vertically downwards.
  • the flag F is connected to the container edge 3 via a predetermined breaking point S. It is closely adjacent to the piercing tool-forming cone 7 and lies in the radial R between the center of the container and the center of the cone 7.
  • the predetermined breaking point S is formed by a cover film 4 which is firmly sealed on and the notch 3 'which partially cuts through the projecting container edge 3 runs approximately tangentially to the circular container edge 3. Taking into account the circular shape of the container outer edge 3 ', a segment-shaped section of the edge 3 still falls in the area of the flag F.
  • the notch 3 "is placed such that the container 1 after breaking off the Flag F remains hermetically closed.
  • the flag F continues beyond the broadened middle section in the embodiment according to FIGS. 1 to 3 into a tongue-like grip tab 10. Its outer edge is convexly rounded and merges smoothly into the circular shape of the container outer edge 3 'via grooves 8, 9.
  • the tool 6 can now be placed on the cover film 4 at any point, preferably near the inner edge, and inserted.
  • the contents of the filling can now be seen from the perforations created. If necessary, two perforations can be made on diametrically opposite edge parts. If there is only one perforation, in which case the filling content can be pumped out through the membrane-like cover film 4, the package can be closed again like a stopper by means of the piercing tool 6.
  • the breaking off of the flag F is promoted by the surface-stiffening effect of the cone 7 in the area near the breaking point, so that the separation is achieved after a small tilting angle of the flag downwards.
  • the latter as has been found, is completed before the tip 5 of the cone 7 approaches the wall 2.
  • the complete covering of the flag by the cover film 4 also leads to a surface-stiffening lamination. Even very flexible film material is given a surprisingly high surface stiffening by the sealed cover film 4.
  • the notch course in the perpendicular to the radial R is the embodiment shown in FIGS. 1 to 3 identified by the line L-L. While the relevant breaking line L-L extends in a stretched manner, in the exemplary embodiment according to FIGS. 4 and 5 it takes a course which corresponds to that of the circular container outer edge 3 '.
  • a cover foil piercing tool 6 of greater overall length is achieved by means of this design, which runs along a partial circumference, but without requiring a greater radial projection.
  • the cone 7 also lies there in an area-widened central section of the flag F.
  • This area widening which also extends up to a fingertip size, runs parallel to the rounding of the cone base in the outward-facing region, and then again in turn through grooves 8 and 9 into a tapering flag. Transition end portion 11 and at the other end to form a handle tab 10 now oriented in the circumferential direction of the container. The latter stands out as a tangible, tongue-like tab.
  • the predetermined breaking points S 1 and S 2 are designed in the form of small material bridges.
  • the predetermined breaking point S 1 lies in the radial R between the container center and the cone center.
  • the second predetermined breaking point S 2 is realized by a material bridge at the end of the flag end section 11, where the end section is rooted in the edge 3.
  • the cover piercing tool 6 can be easily removed from the edge 3 of the container 1, the surface-stiffening function of the cone 7 also proving to promote breakage here.
  • the predetermined breaking point S 1 After severing the predetermined breaking point S 1, it is easy to separate the material bridge of the predetermined breaking point S 2, which binds the long actuating handle in the form of the flag end section 11 to the container, by angling the flag F. This section tapers continuously into the material cross-section forming the breaking points.
  • the cover film tool 6 extends approximately over a quarter circle section of the container edge 3.
