Definitions

  • the invention relates to a packaging container consisting of a body with an approximately rectangular cross section and rounded edges, which is provided with closure flaps at at least one end.
  • the invention has for its object to provide a packaging container of the type mentioned, which can be closed dust-tight.
  • This object is achieved in that two at least partially overlapping flaps are arranged by means of fold lines on the long sides, one of these flaps having such a shape and Dimension has that it fills and stiffens the opening cross-section of the fuselage and lies with its cut edges in particular on the inside of the rounded edges of the fuselage and that the edges between the fuselage and the folded-in flaps, on which cut edges of the container parts would be visible, are sealed in a dustproof manner by adhesive strips are, the adhesive strips in the region of the round edges of the fuselage are not interrupted and are attached both to a closure flap and to an outside of the fuselage.
  • the adhesive strip consists of a shrinkable plastic and is shrunk onto the closure flaps by heating to form a wrinkle-free and tight contact. It may be expedient to press the adhesive strip partially along the straight sides against the closure flaps before heating.
  • the shrinkage of the adhesive strip means that it adapts well to all unevenness.
  • the parts of the container are sufficiently secured against displacement by the adhesive strip, so that gluing between the closure flaps is not necessary.
  • the adhesive strip also covers the cut edges, which are unsightly in corrugated cardboard, and provides edge protection.
  • the adhesive strip can consist of an expanded polyester or polypropylene film.
  • an inner closure flap is designed as a narrow, folded-in strip and the other closure flap filling the opening cross section is on the outside and is supported on the inner closure flap.
  • a very good hold of the closure is also achieved according to the invention in that support flaps are arranged on the narrow sides of the packaging container, which abut the inside of the outer closure flap.
  • closure flap filling the opening cross section of the container body is on the inside and the outer closure flap covers the cut edges at the end of the body and rests on them.
  • the blank 1 consists of two long sides 2, two narrow sides 3 and 3a, the narrow sides 3a being glued to form an overlapping longitudinal seam, and the regions of the rounded edges 4, which are designed so that the cardboard material becomes one on the outer side smooth curve between the long and narrow sides can be bent.
  • at least one of the cover layers is provided in the regions of the edges 4 with incisions running approximately over the entire height of the container, which allow such a bending of the corrugated cardboard.
  • the inner flap 6 and the outer flap 7 are articulated on the longitudinal sides 2 via fold lines 5.
  • the area of the closure flaps corresponds approximately to the opening cross-section of the fuselage 10 erected from the blank 1, but at least the inner closure flap 6 is exactly as large as the opening cross-section, so that when folded (FIG. 2), on all sides, in particular, on the inner surfaces of the opening cross-section also lies in the area of the rounded edges and is clamped under slight tension.
  • a handle opening 8 is provided on the inner closure flap 6, which makes it easier to pull this flap out and is covered by the outer flap 7.
  • the outer closure flap 7 covers the inner flap 6 and also lies essentially on the upper cut edge of the fuselage 10 made from the blank 1.
  • the outer flap 7 is held on the fuselage 10 by a circumferential adhesive strip 9 and at the same time the container is sealed. To open it, just cut the adhesive strip.
  • the container can be provided with a carrying strap 13 which is held on the fuselage in a known manner by means of rivets 12.
  • the carrying strap 13 is preferably fastened with elongated holes 11 and, due to the shape of these holes 11, can be between two positions can be moved. In one position it is at a sufficient distance from the closed flaps 6 and 7 so that it can be gripped for carrying or can also be turned to the side, in the other position (FIG. 3) it is pressed onto the folded-in outer flap 7, so that after opening the container for the first time, the flaps are thereby held in a lockable position.
  • the bottom of the container is formed by an inner closure flap 16, which completely fills the cross section as described above, and an outer closure flap 17, which only partially covers the former.
  • a dustproof closure can be formed by gluing adhesive strips at least around the narrow sides of the fuselage 10 and the rounded edges adjoining them and accordingly on the closure flaps. Another adhesive strip also covers the free, straight end edge of the flap 17. (The adhesive strips in the embodiment according to FIG. 4 are not shown).
  • Fig. 5 shows a container with a plastic part 18 used as the bottom. This is tightly connected to the body 10 of the container by means of an adhesive strip 19, the adhesive strip being glued on as well as on the upper edge of the container so that it is approximately half its width rests on the outside of the fuselage 10 and is glued with its other half width to a base surface provided on the plastic part 18, which approximately coincides with the lower edge of the container.
  • FIG. 6 shows the edge of a blank 1 with the closure parts arranged on it, which can be used, for example, to form a base.
  • the side walls 2 and 3 resulting from the shaping of the fuselage and the rounded edges 4 are indicated in addition to the cut.
  • An adhesive zone 20 serves to form a longitudinal seam between the parts 3a of a narrow side.
  • At the edge of the blank there is an outer closure flap 27, a narrow, strip-shaped inner flap 26 and two support flaps 28.
  • the fold lines 25 of these flaps are offset from one another in accordance with the thickness of the cardboard material so that the outer surface of the outer closure flap 27 lies in the plane defined by the cutting edge 24 of the rounded edges 4, the flap 27 the opening cross section within the rounded Fills edges 4, and that the flaps 26 and 28 abut the inner surface of the outer closure flap 27.
  • the folded edges 25 thus also support the free straight cut edges of the outer closure flap 27. Since the narrow inner flap 26 is essentially shaped to round off the edges 4 adjacent to it, it contributes to the stiffening of the fuselage 10.
  • the folds around the fold lines 25 also secure all four straight sides against bending inwards or outwards.
  • Fig. 7 shows the section through a container end with folded flaps approximately from the blank according to Fig. 6, the cut being made transversely to the closure flap 27, i.e. from one longitudinal side 2 to the other.
  • the outer flap 27 is placed on the folded flaps 26 and 28 so that it is still within the rounded edges 4 and can be supported on the sides 2, 3 of the fuselage 10 via the folded edges 25.
  • the edge of the outer closure flap 27 is cut in such a way that the cutting edge 29 projects so far in the region of the straight sides 2, 3 that it is flush with these sides.
  • the adhesive tape .9 which is only indicated by dash-dotted lines, all joints at the cut edges 24 and 28 are covered and the closure flap 27 is held in the closed position.
  • the adhesive strip 9 is fastened smoothly and firmly against the outer closure flap 27 in the region of the rounded edges 4.
