Definitions

  • the invention relates to a folding box made of cardboard for a roll of cling film and with a tear-off device, wherein the folding box has side and end walls, forms a receiving space for the roll and has an outlet opening for the film and the tear-off device is externally accessible on a side wall in the area a box edge is protruding and extends over a large part of the length of this box edge.
  • the tear-off device is a flat metal strip which is stamped on the edge so that teeth are formed. It is fastened parallel to a long edge of the folding box on a first side wall of the folding box in such a way that its teeth protrude slightly from the adjacent, second side wall.
  • the outlet opening is formed on the other longitudinal edge of this second side wall, at this point the adjacent third side wall is not connected to the second side wall. Rather, the third side wall merges into a flap that is approximately the size of a side wall and that can be folded over the entire surface onto the second side wall. A gap remains between this flap and the second side wall, through which the film can be pulled off the roll located inside the folding box.
  • This roll usually has a stock of 20 or 30 m of film.
  • a disadvantage of the previously known household foil box is that, after tearing off a desired length, the piece associated with the supply roll typically sticks to the saw punched out of metal. If the film is removed again, it must first be detached from the tear-off device. Furthermore, tearing off is often difficult, in particular the beginning of a tearing-off process proves to be difficult. It is seldom possible to keep the tear line exactly on the course of the tear-off device, rather the film tears free - mostly in the last third of the tear line - whereby it is greatly stretched.
  • the invention has for its object to avoid the disadvantages of the carton with cling film of the type mentioned and to further develop the known carton in such a way that a much easier handling is made possible for the consumer, in particular the removal of a new piece including tear-off is easier.
  • the folding box With the design of the folding box according to the invention, a significantly better severing of the film can be achieved. In particular, the start of the tear-off process is much easier. It is no longer necessary to grasp the entire folding box with one hand in order to pull a piece of film pulled out at an angle with the other hand and thereby be able to tear it off at the tear-off device, rather the folding box can be placed anywhere near an edge and both can be Hands are used to peel and separate a piece of film. This has the great advantage that the film remains stretched out and cannot lie on top of one another twice or more. Once it has been placed on top of each other several times, it takes a lot of effort to separate the film. This applies in particular to PE cling films, as they are increasingly used.
  • the folding box according to the invention is also suitable for rolls with larger numbers of meters than is known for folding boxes according to the prior art. Overall, this results in a longer useful life for the consumer.
  • the teeth of the plastic saw perforate the cling film much better than the teeth of the metal bar according to the prior art.
  • the film is held better during the tear-off process, on the other hand, the tear-off process itself also runs better.
  • the outlet opening is formed on a third side wall adjoining the first side wall. It is therefore located in a side wall which is separated from the tear-off device by the first side wall. After each tear-off operation, a piece of film connected to the roll remains on the outside of the first side wall between the outlet opening and the tear-off device. When a new piece is to be removed, it can be easily gripped and pulled so that further stock can be removed from the roll. The one lying on the outside on the first side wall Part is not covered by a flap, as in the prior art, so that detection of the end is not difficult.
  • the outlet opening is a flap which is formed from the material of a side wall.
  • a partially arched dividing line runs in this side wall, which is completed by a folding line forming a joint to form a closed curve.
  • the width of the tongue is advantageously chosen to be somewhat larger than the depth of the plug-on profile.
  • the tongue itself does not have to have a large width, it is used only for fastening the plastic saw and forms an opening in the first side wall, which is otherwise not required. If the tongue is chosen somewhat wider than the depth of the plug-on profile, this plug-on profile is held well.
  • the folding box is made of corrugated cardboard with a wall thickness of about 1.7 mm, Fig. 1 shows the cut.
  • the folding box forms a cuboid, the length is approximately 33 cm, the front surface has the dimensions 7 x 7 cm.
  • the blank forms a first side wall 20 with the dimensions 7 ⁇ 33 cm (same for all side walls) in its central region.
  • This first side wall 20 seen in the figure downwards, is integrally connected to a second side wall 24 via a fold line 22, and upwards it merges accordingly into a third side wall 28 on a fold line 26.
  • all fold lines are shown in dashed lines, all solid lines are dividing lines on which a cut or a punching takes place.
  • a dividing line 30 running parallel to the folding line 22 and at a short distance from it, which ends in the end regions in an arc shape in the folding line 22. It extends practically over the entire length of the fold line 22, apart from approximately 12 mm wide areas at both ends of its arch pieces.
  • This dividing line 30 delimits a strip-shaped tongue 32 which can be folded around the folding line 22. When the folding box is used in practice, this tongue 32, which will be discussed later, is folded onto the surface of the second side wall 24.
  • An outlet opening in the form of a flap 34 is formed in the third side wall 28. It is delimited by an approximately C-shaped dividing line 36 and a folding line 38 which forms a hinge.
  • the dividing line runs essentially parallel and at a distance of about 12 mm from the folding line 26, with lateral space to the narrow sides of the third side wall 28. It then runs in an arc-shaped manner in the vicinity of these narrow sides, the arc pieces continuously opening into the folding line 38.
  • Semicircular punched-outs are also provided in order to be able to grip and open the flap 34. 1 that the flap 34 opens in the direction of the strip-shaped tongue 32.
  • the blank is completed by a fourth side wall 40, which merges upward into an adhesive flap which is glued flat to a region of the second side wall 24 which is lower in FIG. 1 when the folding box is set up.
  • the box is closed in a manner known per se by side flaps, which are not dealt with here.
  • Fig. 2 shows the ready-to-use state of the folding box, in the interior of which there is a roll of cling film.
  • the flap 34 is slightly opened, the slot formed between the free end of the flap 34 and the undisturbed region of the third side wall 28 forms the actual outlet opening for a piece of film 42 that has been pulled off.
  • the resistance to the trigger can be reduced of film 42 can be changed from a supply roll 44 (Fig. 3).
  • the clear film 42 extends so far from the outlet opening that it can be easily gripped. This also remains when a piece of film has been cut to length for the first time by means of the tear-off device 46 described below, then the remaining piece of film 42 is drawn somewhat longer than in FIG. 2.
  • the tear-off device 46 has an elongated plastic saw which is known per se and which is provided with the reference number 46 below. It consists essentially of a U-shaped Clip-on profile, from which teeth protrude in the form of a bar in the opposite direction to the opening of this profile.
  • the teeth are isosceles and project about 2 mm freely, their base is a triangle, they taper to the free end. Teeth are arranged approximately every three millimeters.
  • the U-shaped clip-on profile has clear internal dimensions of approximately 3 x 8 mm, the material thickness is approximately one millimeter.
  • the U-shaped plug-on profile is plugged onto the tongue 32, which is folded into the plane of the second side wall 24, and at the same time onto the part of this second side wall 24 which is covered by the tongue 32.
  • the push-on profile of the plastic saw is attached to the doubled material thickness of the cardboard material of the folding box. Since the double material thickness is about 3.4 mm, but the inside width of the clip-on profile is only about 3 mm, good clamping is achieved.
  • the tooth tips of the plastic saw 46 lie, as is also indicated in FIG. 2, in the plane of the lower surface of the plastic saw 46.
  • the supply roll 44 is located in the square inner cross section of the folding box and consists of a roll on a cardboard tube. The latter is a little longer than the winding of the film in a known manner. As described, the film runs through the outlet opening and, in the orientation of the folding box shown here, hangs downward parallel to the first side wall 20. After a first tear, the free end of the film 42 is in the immediate vicinity of the plastic saw 46.
  • the adhesive flap of the fourth side wall 40 is already connected to the side wall 24, the folding box is flat in the delivery state, two side walls, e.g. B. 20 and 28 and 24 and 40 are superimposed. After unfolding, the end wall on each side only needs to be closed to set up the folding box. Furthermore, in the delivery state, the dividing lines 36 and 30 are not completely continuous, but the tongue 32 and the flap 34 are still over narrow webs that can be easily cut, for example by finger pressure, and interrupt the dividing line 30 or 36 with the remaining side wall 20 and 28 connected. As a result, the folding box is initially closed, which is advantageous for transport, the tongue 32 is only pressed in at the user and the flap is lifted up by reaching under the semicircular punched-out portions, the webs tearing in each case.
