Definitions

  • the present invention relates to a self-closing packaging according to the preamble of claim 1. Furthermore, it relates to a method for filling and closing the packaging.
  • a type of packaging for products that are present in pieces or in portions such as candies or lozenges, has a dispensing opening that is re-closable.
  • the opening and closing is done by moving an inner part relative to an outer part.
  • An opening of the inner part slides under an opening of the outer part, whereby an exit of the interior of the inner part is created and one or more portions or pieces of the product can be output.
  • the inner part is automatically moved back to the rest position, in which the openings are shifted from each other and thus the packaging is closed.
  • the inner part forms a substantially closed space, which receives the goods (product).
  • a package is from the CH-473,012 known.
  • Outer part as well as inner part are essentially the surfaces of a cuboid, wherein the cuboid of the inner part in the direction in which the opening movement takes place, is significantly shortened compared to the outer part. Otherwise, the inner part is dimensioned slightly smaller in order to fit into the outer part while being displaceable therein.
  • the outer part has two openings, namely a first, to which the inner part existing opening can be aligned to represent the product removal opening, and a second opening, through which on the inner part can be pressed to effect this alignment, ie to carry out the above-mentioned movement to open the packaging.
  • a first to which the inner part existing opening can be aligned to represent the product removal opening
  • a second opening through which on the inner part can be pressed to effect this alignment, ie to carry out the above-mentioned movement to open the packaging.
  • EP-A-1 048 577 is a cardboard packaging.
  • On the inner part is formed as part of the wall and then to the surface which is pressed to open and protrudes for this purpose on the outer part, a spring element, in which the wall part is folded inwards.
  • a disadvantage of this solution is that the interior is not a box closed on all sides because of the movable wall parts and the property contained can get into the resilient area where it jam or damage the moving during compression wall sections. It is also not excluded that parts of the material can escape unintentionally from the packaging through the gap between the movable wall parts, in particular after repeated use.
  • the spring action of the kinked carton of the movable wall parts significantly after several operations, whereby the risk increases that the packaging no longer automatically closes properly.
  • Such a package is specified in claim 1.
  • Preferred embodiments and a method for producing the packaging are in the other Claims specified.
  • the packaging 1 consists essentially of three parts: An outer part 3, which essentially has the shape of a cuboid without a lid, an inner part 5, substantially in the shape of a cuboid and a spring element 7 in the space between the outer part bottom 9 and the inner part bottom 11.
  • the inner part 5 is made slightly smaller than the outer part 3, so that it is easily displaced in the latter in the direction of the arrow 13.
  • Both outer part front wall 15 as well as inner part front wall 17 each have a discharge opening 19 and 20, respectively.
  • the inner part 5 can be moved downward, whereby the inner part discharge opening 20 is pushed under the outer part discharge opening 19.
  • the freedom of movement of the inner part 5 is limited by a limiting tongue 24 which projects through a limiting slot 26.
  • left outer part narrow side 29 is a window 31 through which the tear strip 33 is accessible.
  • the tear strip 33 connects the inner part 5 and outer part 3 and thus blocks the movement according to arrow 13. Only after tearing off the tear strip 33, the inner part 5 can be moved in the outer part 3 down to remove the goods contained.
  • the tear strip 33 thus serves as Clearö Maschinenssch.
  • Fig. 2 shows a one-piece blank from which the packaging according to Fig. 1 made in a simple way.
  • the lower half 37 represents a known in its general structure blank to form a cuboid box. It forms the inner part. 5
  • the upper half 39 structurally similar to the lower half 37, but it lacks the lid located in the figure right 41 to form the inner lid 22.
  • iensteilabrisk 37 and outer portion 39 are joined together by the tear strip 33.
  • the connection between tear-off strip 33 and inner part section 37 or outer section section 39 is designed as tear-open perforations 43.
  • the blank 35 is wound up starting with the inner part section 37, so that the wall adhesive tabs 45, 47 for the outer part 3 or inner part 5 with the opposite (in Fig. 1 left) narrow side or the likewise opposite Rear wall 52 of the inner part 5 can be glued.
  • the inner-part bottom flaps 54 and their gluing the inner-part bottom 11 is formed.
  • the inner part bottom flaps 54 are formed as elongated tabs as extensions of the inner narrow sides 55. They thus protrude beyond the lower edge of the outer part 3, when the tabs 56 are folded outwards.
  • the inner-part bottom flaps 54 can therefore be mechanically gripped, superimposed and glued inwardly to form the bottom 11.
  • the fundamentally possible design of the inner part bottom flaps analogously to the outer part flaps 56 leads to a very high outlay for the mechanical closure or even requires manual labor.
  • the spring 7 is placed and then the outer part bottom 9 formed by folding the outer part bottom flaps 56 and their bonding. After these operations, the packaging is functional, only the inner part cover 22 is still open to fill the estate can. If the product is in the packaging, the inner part 5 is closed by folding and gluing the inner part lid flap 41.
  • Folding, gluing, inserting the spring in the predetermined orientation and the filling and closing can be performed by machine, resulting in a high degree of rationalization.
  • FIGS. 3 and 5 show the spring 7 in different views.
  • it is a Z-shaped bent part made of plastic.
  • plastic Through the use of plastic, it is possible to hold the restoring force of the spring over a plurality of opening operations at a sufficiently high level to ensure a safe sliding back of the inner part 5 in the closed position, without having to accept an unnecessarily high initial spring force.
  • shape of a Z instead of a zigzag-shaped course according to the prior art, which at a given distance between the upper surface 61 and lower surface 63 of the spring 7, which abut the outer part of the tray 9 or inner part bottom 11, a much larger Hub results.
  • angles 65 decrease. at about 30 degrees.
  • thermoplastics with spring or rubber-elastic properties have proven to be suitable, for example of the type POM (polyoxymethylene), PA (polyamide) and also biodegradable variants, e.g. based on cellulose.
