Definitions

  • the present invention relates to a gusseted paper bundle such as a gusseted bag or bag, a method for producing such a gusseted paper bundle and the use of the gusseted paper bundle according to the invention.
  • Transport containers made of paper have the advantage that they do not regularly pollute the environment and, for example, can be easily recycled or decomposed. Since they are based on renewable raw materials, their energetic utilization does not generally contribute to a worsening of the carbon dioxide balance. However, practicable handling in daily use usually presupposes that such paper bags or pouches can be filled easily and without problems. Self-standing paper bags, which can be filled with both hands even when empty without the help of third parties, have hitherto had to be large in size and have a block bottom. Its production is material-intensive and often requires additional work steps. The present invention was therefore based on the object of making paper bags and pouches available which do not have the disadvantages of the prior art and which, in particular, are self-standing, regardless of their size, even when empty.
  • a gusseted paper pack such as a gusseted paper bag and a gusseted paper bag was found with a pack base or a pack base area, a front wall with an upper pack edge and a pack inside and outside as well as opposite longitudinal fold edges, a rear wall with a top pack edge and a pack inside and a pack outside and opposite longitudinal fold edges, and opposite first and second side walls, each with an upper container edge and a container inside and an outside, each containing at least one, in particular precisely one, side fold.
  • the front wall is, in particular along a first folding edge, in one piece into a first part of the container base area with a first outer edge
  • the rear wall also, in particular along a second folding edge, in one piece into a second part of the container base area with a second outer edge.
  • this gusseted paper pack is in the area of the transition from the front wall to the first part of the pack base area, in particular in the area of the first folded edge, in particular on the first folded edge, at least in sections, in particular completely, with a first break and in the area of the transition from the rear wall to the second Part of the bottom area of the container, in particular in the area of the second folding edge, in particular on the second folding edge, is provided with a second fold at least in sections, in particular completely.
  • the first side wall merges in one piece, in particular along a third folded edge, into a third part of the container base area
  • that the second side wall merges in one piece, in particular along a fourth folded edge, into a fourth part of the container base area and that in the area of the transition from the first side wall to the third part of the container base area, in particular in the area of the third folding edge, in particular on the third folding edge, there is a third rupture at least in sections, in particular completely
  • the first and second pre-folds and in particular also the third and fourth pre-folds are preferably pre-prepared pre-folds.
  • a pre-break is generally understood to mean the scoring of paper with pre-break tools known to those skilled in the art, for example embossing tools.
  • pre-break tools known to those skilled in the art, for example embossing tools.
  • the paper With the application of a crease, the paper is generally changed in such a way that a sharp-edged fold is guaranteed for subsequent folding processes.
  • a pre-break can be produced by a so-called rotating creasing knife against a rubber shaft or base. Too much creasing can damage the paper and then tear the material in the fold during production. Inaccurate folds can result if the creases are too small. A fold line is thus indicated with a fold, but without the fold being formed.
  • the first and second fold edges and in particular also the third and fourth fold edges represent fold edges produced downstream in the region of the first, second, third and fourth pre-folds.
  • Such gusseted paper packs according to the invention solve the problem on which the invention is based, namely to provide a size-independent, self-standing paper container, particularly well in which the first and second folds and in particular also the third and fourth folds are on the inside of the pack, from the front wall and rear wall and, if appropriate, from first side wall or second side wall are present.
  • the upper pack edge of the front wall is below the upper pack edge of the rear wall when used in accordance with the generic type.
  • a generic use occurs, for example, when a gusseted paper bag is carried by the handles so that the bottom of the bag points downwards.
  • a gusseted paper pack that is placed on a base and can be filled with both hands without the help of a third party also represents a generic use.
  • the first part of the container base area of the gusseted paper container according to the invention forms an essentially rectangular base area.
  • the first part of the container base area preferably has a greater extension (A) away from the transition of the front wall into the first part of the container base area, in particular from the first folding edge, than the second part of the container base area has an extension (B) away from the transition of the rear wall in the second part of the container base region, in particular from the second folding edge, and specifically in particular to the extent that the upper container edge of the front wall is below the upper container edge of the rear wall.
  • the first part of the pack base area covers the second part of the pack base area at least in sections, in particular essentially completely.
  • this also results in a particularly dense and stable floor design.
  • the first part of the container base area extends essentially up to or adjacent to the transition the rear wall into the second part of the container base area, in particular the container base area essentially up to or adjacent to the second folded edge.
  • Another particular advantage of the gusseted paper pack according to the invention is that the amount of adhesive required to form a tight pack bottom area can be kept very small. This is achieved, for example, in that the first part of the container base area is connected, in particular glued, on the inside to the second part of the container base area, in particular exclusively, adjacent to the transition of the rear wall into the second part of the container base area, in particular to the second folded edge.
  • the front wall, rear wall, first side wall and second side wall as well as the first, second, third and fourth part of the pack base area are preferably in one piece.
  • the first part of the container base area of the gusseted paper container according to the invention is preferably designed in one layer or predominantly in one layer. This also contributes to a saving in material during production.
  • a particularly advantageous production and handling is regularly achieved with such side-folded paper bundles according to the invention, in which the distance between the first outer edge and the first prefold is essentially in the range from half the width to the width of the first and/or second side wall.
  • the distance between the second outer edge and the second fold is essentially in the range from one third of the width to two thirds of the width of the first and/or second side wall, preferably essentially in the region of half the width of the first and/or second side wall.
  • the gusseted paper pack according to the invention has a first carrying handle, in particular paper carrying handle, attached to, in particular, the inner wall of the pack, the front wall and/or, in particular and, via a second carrying handle, in particular paper carrying handle, attached to, in particular the inner wall of the pack, the rear wall .
  • a first carrying handle in particular paper carrying handle
  • the gusseted paper pack according to the invention does not have any carrying loops or handles and also no grip holes, it can generally be referred to as a gusseted bag.
  • At least one reinforcement layer can be provided in the area where the handles are attached to the front wall and/or, in particular, at least one reinforcement layer can be provided in the area where the handles are attached to the rear wall.
  • the paper used for the gusseted paper pack according to the invention has a grammage in the range from 30 g/m 2 to 120 g/m 2 , preferably in the range from 40 g/m 2 to 90 g/m 2 .
  • the paper of the front wall, rear wall, first side wall and second side wall as well as of the first, second, third and fourth part of the pack bottom area is laminated on the inside and/or outside or with a sealing wax is provided.
  • Moist objects can also be transported and stored with such gusseted paper bundles according to the invention.
  • such gusseted paper containers are suitable as compost collection and/or carrying containers.
  • Particularly expedient embodiments of the gusseted paper pack according to the invention also include a transverse fold line or transverse fold edge, which extends in the area of the first part of the pack base area at a distance from the first outer edge, in particular essentially parallel or parallel to the first outer edge, in particular in the area between the first and second side walls.
  • An embodiment of the side-folded paper pack according to the invention is particularly preferred in which the transverse fold line or transverse folding edge is spaced apart from the first outer edge in the area of the first part of the pack base area, in particular essentially parallel or parallel to the first outer edge, and in the area of the second part of the pack base area from the second outer edge, in particular essentially parallel or parallel to the first outer edge, and in the area of the third part of the container base area at a distance from the second outer edge, in particular essentially parallel or parallel to the first outer edge, and in the area of the fourth part of the container base area at a distance from the second outer edge, in particular essentially parallel or parallel to the first outer edge, in particular continuously, extends.
  • particularly dense container bases are obtained.
  • steps of introducing one or a multiplicity of linear pre-folds and the attachment of the first and second perforation line and optionally the attachment of the first and/or second carrying handle can be carried out sequentially in any order or also simultaneously. It is also possible to carry out two steps in pairs simultaneously.
  • This step is regularly carried out first by the user of the gusseted paper bundle according to the invention.
  • the formation of longitudinal fold edges to obtain the front wall, rear wall and first and second side wall and the formation of the side folds of the first and second side wall can be compared to the overlapping bringing together of the first and second side edge of the paper web to form a tube and connecting the first and second side edge be ahead of time.
  • These two method steps can be carried out essentially simultaneously, particularly in the case of mechanical production.

  • the gusseted paper pack according to the invention has a uniformly small thickness in the flat, stackable state, for example compared to block-bottom bags. This can be attributed to the fact that with the gusseted paper packs according to the invention in the flat, stackable state, as is initially obtained in the manufacturing process, the pack base as such is not yet formed and therefore cannot be applied.
