Definitions

  • the present invention relates to a ripping device for a blank.
  • a blank may for example consist of a semi-rigid material, such as corrugated cardboard.
  • the invention also relates to a product of such a blank, for example a cardboard.
  • the European patent address EP 0 571 197 B1 discloses a ripper for corrugated board packaging.
  • the invention also relates to a container.
  • This can be made of double-sided corrugated board, that is a corrugated board with two smooth layers and a corrugated intermediate layer.
  • a separate tear strip is provided for the purposes of the invention.
  • a first weakening line is provided for the tear tape .
  • a second weakening line is still provided, which is intended to cooperate with a second edge of the band.
  • a special initial tab is formed on which the band can be grasped.
  • the invention is aimed to exploit the cutting action of the edges of the tear strip.
  • the weakening lines are intended to provide smoother cut edges.
  • the British patent GB 777,079 also relates to a container which can be made of a corrugated board material. Again, a tape is used, which in this case is adhesively bonded to the inside of the walls of the box. Also, various lines of weakness are provided to allow the opening of the container through the belt.
  • the patent DE 102 27 050 B3 also discloses a rip cord for corrugated board.
  • the tear line is created by cutting through both cover papers completely.
  • the wave paper should not be cut at all or only partly.
  • the cuts in both ceiling layers should be exactly opposite each other.
  • the publication DE 44 28 185 A1 discloses an apparatus for making tear perforations.
  • it is also a corrugated product.
  • the perforation should consist of separation points and scribe lines. Particular attention is paid to the separation points. These are to be produced by pressing roof-like recesses into the corrugated cardboard material or embossed.
  • the appropriate preparation of the corrugated material therefore requires an autwismees tool, which is presented as part of the invention.
  • the roof-like recesses will in turn affect at least the buckling stability of the corrugated cardboard in noticeably unfavorable manner.
  • the U.S. Patent 3,905,646 discloses a package for beer bottles with a ripper.
  • the present invention desires to provide a convenient ripping device in a simple economic manner with machines commonly used in corrugated board processing. This should be inexpensive to produce in a mass process, not unduly weaken the material and produce a smooth clean break line.
  • the invention thus relates to a tearing device.
  • a device for a blank of folding material may comprise both the folding material complementary elements, as well as weakening points, which may arise by omitting Faltmatarial in certain areas. Additional elements are, for example, tear threads. Such a tear thread can also be provided in the context of the present invention, but it is not required.
  • a first and a second Schicachungaline central elements of the tearing device can be listed, for example, by scratching and are also referred to below as the first and second scribe line.
  • the process by which the Line of weakness or weaknesses are produced, but rather on the result of a selective weakening of the folding material.
  • the tearing device is suitable for all typical folding materials, ie in particular for flexible, for example semi-rigid, materials, which also include textile materials and plastic materials.
  • Typical folding materials are paper and board materials.
  • a particularly preferred material herein is corrugated board.
  • Corrugated board typically consists of at least one intermediate layer which is corrugated. It also has one, but often two outer layers.
  • a preferred folding material is a three-ply, which has a wavy intermediate layer which lies between a smooth outer layer and a smooth inner layer.
  • Another preferred folding material is a five-ply. This has an outer smooth layer, a first corrugated layer, a smooth intermediate layer, a second corrugated layer and an inner layer.
  • outer layer and the inner layer need not differ in their properties.
  • outer layer and inner layer therefore usually designate two identical layers.
  • inner liner will of course always be used for the innerliner facing the product.
  • the outer layer and the inner layer may also be made of different materials.
  • the outer layer is made of a smoother and / or heavier material than the inner layer.
  • the basis weight of an advantageous outer layer could be 180 g / m 2
  • the basis weight of an inner layer or intermediate layer is only 125 or 140 g / m 2 .
  • blank is to be understood in the context of this invention in a broader sense. It may be a sheet of folding material, which is therefore typically further processed. It may be a typical blank, which is contoured and obtained for example by punching. This is usually flat after punching, but can be transformed into a space-filling product by folding and erecting steps. However, the term blank is also intended to be used herein for such products resulting from the processing of blanks.
  • corrugated cardboard folding materials are typically packagings, such as cartons, or also goods displays.
  • the tearing device has a course direction, which is given by the course direction and the first and the second scribe line. If these lines should not be run in parallel once, it should be averaged.
  • the tearing device extends over a first length. Perpendicular to the direction of extension, it extends over a first width.
  • the first width is generally simply the distance of the first scribe line from the second scribe line.
  • the separation of different parts of the blank takes place after tearing along a tear line. According to the invention results in a smooth tear pattern, which can be well described by a line, but should arise once a slightly rough or jagged image, it is by averaging over a certain length to determine the tear line.
  • the first width is to be selected with consideration of the folded material thickness.
  • the first score line and the second score line should be relatively close to each other.
  • the distance may be, for example, 0.1 times or 0.25 times or 0.5 times, single, double or more of the pleated material thickness. However, this distance should be less than 10 times, preferably less than 7 times or 5 times or 3 times the thickness of the folded material.
  • Particularly useful ranges for the first width are 0.25 times to 5 times the pleated sheet thickness, or 0.5 times to 1.5 times or 0.75 times to plain the pleated sheet thickness.
  • the tear line according to the invention runs along the first score line.
  • the first scribe line comprises a scoring of the outer layer. It has been shown that it is sufficient if the first scribe carved only the outer layer. It is alternatively also considered that the first scribe is the outer layer and an adjacent intermediate layer.
  • the first scratching can be a scratching that is continuous over the entire first length.
  • the first score may also be a perforation. In particular, a perforation with few retaining webs and long cutting lines would be suitable. For example, a suitable pitch would be one in which the cut length is at least 70% or 80% or even 90% of the total first length.
  • the second scribe comprises a perforation of the inner layer.
  • only the inner layer is scratched by the second scribe even.
  • the second score scratches the inner layer and at least one adjacent intermediate layer.
  • the second score scratches the inner layer and all intermediate layers. Under scratches is in connection with this second scribe perforation to understand.
  • Such a perforation thus produces cuts and holding webs in the scribing direction (sometimes also called breakpoints). It is expedient if the holding webs in the scribing direction occupy at least 10%, 20% or 30% or more of the scored stretch.
  • the length of the holding webs can be adapted, for example, for a carton or a merchandiser to the required stability, in particular to the required stacking crush pressure or BCT value. In order to ensure easy tearing you will usually go but not far beyond these requirements.
  • the length of the holding webs in the direction of scribe on the Faltmaterialdicke may be about 50% to 200% of the pleated material thickness.
  • a range of 80% to 120% has proven to be particularly advantageous. This results in holding webs of approximately square cross-section, holding webs thus their thickness (measured in the direction of Faltmaterialdicke) and their length (measured at the scribing) approximately equal to each other.
  • the second scribe line For example, if a three-ply corrugated cardboard (about 2 mm thick) is used, it is expedient for the second scribe line to provide cuts of 5 mm in length and holding webs of 1.5 mm in length. Furthermore, it is expedient for this Faltmaterialdicke to provide the first scribe line and the second Riztline at a distance of 1.5 mm.
  • the second scribe line is expedient for the second scribe line to provide cuts of 7 mm in length and retaining webs of 2 mm in length. Furthermore, it is expedient for this Faltmaterialdicke to provide the first scribe line and the second Riztline at a distance of 2 mm.
  • a five-ply corrugated cardboard of about 3 millimeters in thickness (consisting of a smooth, a corrugated, a smooth, a corrugated, and a smooth sheet, a so-called "EE wave” in this order) is used in this order it is useful for the second scribe line to provide cuts of 7 mm in length and retaining webs of 2 mm in length. Furthermore, it is expedient for this Faltmaterialdicke to provide the first scribe line and the second Riztline at a distance of 2 mm. In an EE wave, the second scribe line can also score both wavy layers and the smooth interlayer.
  • the course can be curved in many ways and in any case comprise at least one arc.
  • a carton of a folding material comprising a tearing device in the manner described and claimed herein.
  • at least one sidewall may comprise a tearing device. It is advantageous if all side walls or at least two or three adjacent side walls have a circumferential tearing device.
  • a tearing device which rotates about three side walls, it is possible to produce by tearing a lid, which is held by the other, usually fourth side wall, and thus (supported by this) can be opened. If a revolving around all four side walls ripping device is provided, even the complete removal of the lid is possible. It is also useful if a recess is provided adjacent to the tearing device.
  • a recess adjacent to the first score may be advantageously designed as engagement hatch for a finger, for example, circular or semicircular. Such a recess then makes it possible to exert pressure on the inner layer of the folding material with at least one finger and thereby initiate the tearing.
  • Another inventive carton has a lid and a closure flap connected to the lid.
  • the carton also has at least one wall section.
  • the locking tab have the tearing device.
  • the locking tab can in appropriate Way are connected to the at least one wall portion of the carton.
  • an adhesive compound into consideration.
  • Plug connections can also be durable, for example due to entanglements.
  • the locking tab with a part of the carton, preferably a wall portion are connected.
  • the tear line then allows the release of the locking tab of the wall portion without having to solve the original connection with the wall portion. Therefore, this compound can be stable and durable.
  • the tearing of the closure tab along the tear line of the tearing device then allows the carton to be opened.
  • the tearing device can be arranged so that the closure tab is divided into a first section and a second section.
  • the first section of the closure flap can then be permanently connected to a wall section.
  • the first section can be separated from the second section. The severed second portion may continue to remain connected to the lid. After separating the second section but the box can be opened.
  • a finger recess adjacent to the tear line of the tearing device is particularly contemplated that the tearing device runs along a V-shaped line. It is particularly advantageous if the finger recess adjoins the vertex of the V-shaped line.
  • Fig. 1 shows a section of a blank 10, which has as an essential element, an inventive tearing device 12. As a rule, as far as the blank 10 extends beyond the section shown, the tearing device 12 also extends beyond this cutout.
  • Fig. 1 shows a plan view of the outside of the blank.
  • Fig. 1 is related to Fig. 2 . 3 and 4 which, when taken together, allow a better understanding of the tearing device as a whole.
  • Fig. 2 shows a view of the inside and the 3 and 4 show two cross sections.
  • the first score line 18 can be seen. This scores the blank from the outside, it represents a continuous scribe.
  • the first score line 18 extends relative to the blank 10 in a position which is indicated by two arrow marks and designated P1. In Fig. 1 Also marked is another position P2. There runs the second score line 20, but which can be seen only in the following views.
  • Fig. 2 shows now a plan view of the inner layer 16.
  • the course of the second score line 20 This is designed as a perforation and accordingly has a plurality of web pieces or retaining webs 22. Since the first scribe line 18 does not scratch the inner layer 16, this is in Fig. 2 not visible. Their position is, however, marked by two simple arrows and the reference P1. The more accurate position of the first score line 18 and the second score line 20 to each other can be seen in the cross sections, which are shown below.
  • Fig. 3 shows a cross section along the line III-III.
  • the folding material assumes a folded material thickness D in this cross section.
  • the folding material for the Blank 10 consists of an outer layer 14 and an inner layer 16. These include an intermediate layer 24 a. This is executed wavy.
  • the illustrated folding material can therefore be thought of as a typical three-ply corrugated board.
  • a first scoring line is introduced into the outer layer.
  • a trough runs behind the scribe line.
  • the first score line 18 would typically not score the liner 24. It is even preferred within the scope of this invention that the first score line 18 be positioned relative to the corrugations of the spacer 24 so as not to be scribed.
  • the first scoring line 18 is preferably positioned at the level of a wave trough (which appears in the scribing direction) of the intermediate layer 24. Alternatively, however, it is also considered that one takes the full or partial scratching of the liner 24 in purchasing.
  • the second score line 20 is provided as a perforation, which shows holding webs, and this cross section is guided in the cutting plane by a holding web, located in the position P2 no scratching of the outer layer 14, inner layer 16 or the intermediate layer 24.
  • the folding material also in the region of the tearing device 12 overall good stability.
  • Fig. 4 shows a cross section along the line IV - IV of Fig. 2 , In the amount of the position P1, the scratching is recognizable by the outer layer 14 again. In this cross-section, however, also recognizes the second score line, which scratches the inner layer 16 and the liner 24. It is advantageous if, in the context of this invention, the second score line goes somewhat deeper into the fold material and thus in particular into the intermediate layer 24 than the first score. It may also be advantageous to position the second score line 20 in such a way that it always strikes a wave peak of the intermediate layer 24 (appearing in the scribing direction). At low scratch depth is thus always achieved a weakening or complete separation of the intermediate layer 24 in this way.
  • Fig. 5 shows a perspective view of a carton 30 from a blank.
  • This perspective view is reproduced somewhat schematically here for reasons of simplification.
  • the lower part or receiving part 32 of the carton For example, if the carton serves to deliver goods, they can be accommodated in receiving part 32. It can also be seen the lid part 34, which forms the top of the carton. Between the receiving part 32 and cover part 34 extends circumferentially on all (visible and non-visible) sides of the carton 30 a tearing 12. At the front of the carton this tearing device runs deeper than on the side panels. Further, a punched hole is provided centrally on the front, which creates an opening 36. Through this breakthrough 36 can easily be performed a finger. This can then exert pressure on the inner layer of the blank.
  • the carton 30 is torn open along the tearing device 12.
  • the tearing device 12 rotates around the entire carton 30, it is thus possible to completely separate the lid part 34 from the receiving part 32.
  • the cover part 34 can then be disposed of. What remains is the receiving part 32, which presents goods in an easily accessible manner. In this way, goods can be conveniently placed in a supermarket shelf.
  • Fig. 6 shows a blank 40 for a carton, as in Fig. 5 was shown as carton 30.
  • the cut is related to Fig. 5 self-explanatory; Therefore, not all details, but only the essential parts were called.
  • the blank consists essentially of wall parts 42 and tabs 44.

  • the wall parts 42 form the side walls. At this time, the areas 42A and 42B become the rear wall of the carton.
  • the regions 42C and 42D form the sidewall of the carton.
  • the areas 42F and 42G form the front wall of the carton and the Areas 42A and 421 form the other side wall of the carton.
  • the carton bottom is formed by the tabs 44A, 44C, 44F and 44H.
  • the carton top is formed by the tabs 44B, 44D, 44G and 441. These tabs are usually closed after loading the boxes with goods and
  • a tearing device can now be guided in such a way that a very useful carton is produced. In this can then be easily separated for a receiving part and cover part and on the other hand can be generated by the leadership of the tear line a pleasing and useful designed receiving part.
