Definitions

  • the present invention relates to an opening arrangement for packing containers comprising a wall with a pouring opening and a tear-off cover strip applied over the same in a sealing manner.
  • Packing containers of the non-returnable type are used for the packaging of various contents such as milk, juice and the like.
  • the packing containers are usually manufactured by folding and sealing of laminated material in the form of sheets or a web which comprise at least on the outside a layer of thermoplastic material serving on the one hand as a liquid-tight layer, on the other hand makes possible the sealing together of the packing container.
  • the packing container is usually provided with some form of opening arrangement, e.g. in the form of a cover strip which covers a pre-punched pouring opening in the wall of the packing container and can simply be torn off when the packing container is to be opened and the contents are to be emptied out through the pouring opening.
  • the pouring opening is customarily placed near the edge of one wall of the packing container, in particular a plane top wall.
  • the cover strip is applied over the pouring opening and is sealed to the wall material around the pouring opening so that a completely liquid-tight seal is achieved.
  • an opening arrangement for packing containers comprising a wall with a pouring opening and a tear-off cover strip applied over the same in a sealing manner has been given the characteristic that one end of the cover strip is doubled and given the form of a grip-lug, the cover strip having a moulded part which provides a gap between the free end of the grip-lug and the main part of the underlying main part of the cover strip.
  • the packing container shown in fig.1 is of a known type and is made from two laminated sheets of packing material which on the outside have layers of thermoplastic, that is to say heat-sealable, material.
  • One sheet is bent into U-shape and forms a back wall 1, a bottom wall 2 and a top wall 3 of the packing container.
  • the other sheet too is bent substantially into a U-shape and sealed to the first sheet so that it forms a curved casing wall 4 for the packing container.
  • the two sheets are heat-sealed to one another at their contact surfaces.
  • This known package type is chosen only as an example of a suitable packing container on which the opening arrangement in accordance with the invention can be used, but it is understood that any known or new type of packing container whatever which has a substantially plane container wall can be provided with an opening arrangement in accordance with the invention.
  • the one container wall of the packing container shown, more particularly the top wall 3, is provided with a cover strip 5 which is applied over a non-visible pouring opening in the top wall 3.
  • the cover strip 5, which is shown more clearly in fig.2, has a doubled front end which serves as a grip lug 6.
  • the grip-lug 6 is separated from the main portion of the cover strip sealing the pouring opening by a folding line 7 which extends substantially along the edge line of the container wall 3.
  • the grip lug 6 is folded over about 180 0 in relation to the main part of the cover strip and situated with its free edge 8 on a level with the underlying pouring opening which is not visible in fig.2 but whose contour is indicated by a moulded, recessed part 9 of the main part of the cover strip, this part having a size and shape which substantially correspond to the underlying pouring opening.
  • the moulded part 9 extends so far down into the pouring opening that it can serve as a reclosing element, since the contact between the edges of the moulded part 9 and the edges of the pouring opening provides a friction grip which retains the cover strip relatively securely over the pouring opening when the cover strip is applied again in its original position after the opening of the packing container.
  • the doubled grip lug 6 Since the doubled grip lug 6 is folded over about 180° and thus lies flat against the top portion of the packing container, no part of the grip lug will project from the top wall 3 either, which also contributes to the prevention of any unintentional opening.
  • it may be suitable in certain cases, e.g. when a material is used for the manufacture of the cover strip 5 which is hard to fold, to seal the grip lug 6 to the cover strip 5. This is accomplished by a detachable seal along the edges of the grip lug 6 and in particular by elongated sealing zones along the longitudinal edges of the cover strip 5 on both sides of the moulded part 9.
  • the moulded part 9 may be utilized for the reclosing of the packing container by virtue of its friction contact with the edges of the pouring opening.
  • This moulded part may be in the form of a semicircular raised part or be constituted of two parallel projecting zones which prevent the centre portion of the free edge 8 of the grip lug from resting fully against the underlying main part of the cover strip 5 when the grip lug 6 is folded over about 180°.
  • this design of the cover strip in accordance with the invention it is likewise possible to prevent unintentional unfolding of the grip lug 6 by providing seals of appropriate strength at the free corner or parallel edges of the grip lug.
