Definitions

  • the invention relates to a bag made of plastic film according to the preamble of claim 1.
  • Bags of plastic film in particular for the packaging of lumpy goods, such as rolls of toilet paper, disposable towels, children's diapers, sanitary napkins u. Like. Especially light material often contain pieces in a side by side and / of superimposed shape.
  • a film material is both single-layer (mono) film as well as multi-layer (coex or laminate composite) film into consideration.
  • extremely thin foils of eg only 40 ⁇ thickness to use.
  • these give the content thanks to a corresponding tensile and tear strength and a shape closely adapted to the content sufficient support and sufficient dimensional stability as a total packaging. However, this is no longer the case when the bag is broken.
  • the composite With the removal of a part or individual pieces of goods, the composite is lost and the bag loses its shape and is disposed of. This, and also the division of piece goods, especially in the case of many-part contents, into individual, needs-oriented piece goods groups then forces the packaging to be dispensed with. The goods are loose and without cohesion for handling and otherwise unprotected.
  • a bag according to the preamble of claim 1 is known from DE 20 2006 015 505 U1 in which a bag with a dividing plane can be torn open along weakening lines and then unfolded, thereby exposing a cover lug with which at least one side of the torn bag can be covered along the dividing plane.
  • partial coverage and thus protection of the goods contained is at least partially achieved.
  • a cover with a loose cover tag is not suitable for keeping the covered part of the product in its shape. It is also to a limited extent able to provide protection against dust or other soiling as well as protection against crumpling or scratches on the surface.
  • the object of the invention is to provide a bag of the type considered here in such a way that it retains after opening and partial removal of goods, the remaining goods in a manageable, coherent form and protects against contamination and use loads, for such packaging in particular the For bulk goods to demanding low cost of materials, the simple mechanical manufacturing capability and further the simple machine fillability of the packaging must be maintained as the manufacturer of the goods.
  • this object is achieved by a bag according to the preamble of claim 1, starting with the characterizing features of claim 1.
  • a packaging line of weakness can be any part of the packaging then separate in a closed form and retains its uniform handling and protection of the contents. But even if the weakening line is not formed completely encircling and only a folding of the packaging allows it remains unapprehended on one side of the division level and holistically galleryammmenbonoldd. This also provides good protection of the content.
  • partition walls also provide a favorable during transport and storage subdivision of the content. Especially lumpy goods in the bag are better fixed and load the outer walls less in any handling or impact load, so that even with the extremely thin films improved robustness of the bag with the partitions can be achieved.
  • the partitions can be attached as individual partitions each for themselves on the main walls and possibly also on the narrow walls. But they can also be connected in a folded form with each other, so that they are connected in the region of a fold line with one of the main walls, wherein in the region of this fold line a line of weakness for the Divisibility is to be provided, which should then run at least near the division level.
  • a particularly advantageous embodiment of the intermediate walls for mechanical production takes place with a tubular initial shape, wherein the hose is attached to both opposing main walls, on both sides of two parallel attachment lines, between which a line of weakness for separation and to move apart of the two partitions are provided ,
  • the attachment to the main walls and possibly also on the narrow walls can be done by common means. Sealable sheet material will preferably be secured by heat sealing. In addition, in the field of plastics, fastening techniques such as welding or gluing are also considered.
  • lines of weakness can in principle be formed in various ways, for example by score lines and tear lines in the material.
  • perforation lines are suitable for marking a tearing.
  • one or more of the layers may be severed and thus give lines of weakness.
  • Line of weakness may also be provided between the dividing planes to provide openings for easy tearing of the partitions formed by the partitions To allow bag sections.
  • handles may be preferably provided on narrow walls for handling.
  • the unfilled bags are preferably delivered in a prefabricated but open along a narrow side shape so that the lumpy goods are inserted in a predetermined direction before the package is closed by sealing or welding.
  • the narrow walls on the filling side initially only as an extension of the adjacent walls, especially the main walls are present and are then brought in the desired shape after filling by folding and sealing or welding in their shape.
  • a bag 1 for packaging rolls of toilet paper is shown together with rolls 2 packed therein, which are arranged in three adjacent 2-column.
  • the bag 1 consists of a very thin plastic film of sealable material, in particular polyethylene (PE) with a film thickness of 40 ⁇ or even less.
  • PE polyethylene
  • the bag 1 is shown as enclosing the rollers 2 in a spacious manner.
  • a tight-fitting packaging is common, so that the bag is to handle as a unit together with the packaged lumpy goods.
  • the bag 1 can be thought of as starting from a cuboid shape into main walls, namely a front main wall 3 and a rear main wall 4, parallel to the front main wall 3, into two (upper and lower) narrow walls 5, 6 and into lateral narrow walls 7 , 8 members.
  • the interior of the bag 1 is divided according to the arranged therein in adjacent columns rollers 2 by two graduation levels 9,10, marked in the main walls and the lower and upper narrow walls respectively by lines of weakness 11,12, a slight tearing of the bag 1 and tearing off a Allow bag part.
  • the bags are also divided by intermediate walls 13,14,15 and 16 in the region of the two graduation levels, ie in pairs closely next to and on the one and the other side of the dividing plane.
  • the intermediate walls are formed in pairs by a tube 17 made of plastic film, as in Fig. 2 is shown.
  • This hose 17 has at least mentally predetermined sealing lines 18,19 and 20,21, which come in pairs to the plant with the front main wall 3 and rear main wall - respectively on the inside - and seal on which the tube shape on both sides of the line of weakness 11 and 12 respectively is.
  • the inserted tube 17 has between the sealing lines each have a line of weakness 22 and 23 in the form of a perforation, so that when tearing the package along one of the dividing planes 9 or 10 each half of the tube on one side and the other half on the other side remains. On each side then one of the two partitions (tube halves) is exposed as a partition wall.
  • FIG. 3 is still schematized in a plan view a complete, to be handled as a unit bag packaging 1 with rollers 2 contained therein.
  • the Fig. 4 shows the broken along the dividing plane 10 bag from which arise with the division two round packaged sub-units 24 and 25, which are to be handled by itself with the roller column enclosed therein and protect the rollers from contamination.
  • an embodiment of the bag is possible in such a way that for each division level 9,10 only one side a single partition is provided so that the tearing of the packaging along the dividing plane only on this side leads to a closed and packed bag part, the other side but then it is open. If, for example, all rolls of an individual item are to be regularly removed from packaged roll goods or if (larger) rolls are stored individually in a bag part, the dividing walls need not be provided twice.
  • the Fig. 5 illustrates that the bag 1, despite its complex interior design, is flat in manufacturing and flat fold after production for shipping.
  • the front main wall 3 is largely broken away, as are parts of the upper narrow wall 5, to represent the inside of the rear main wall 4 arranged and each formed by a tube 17 partitions 13,14,15,16.
  • the partitions are folded in the manner of a "flat" tube to one side and to the other side, so that the front main wall 3 and the rear main wall 4 come into contact with each other.
  • This folded shape of the upper narrow wall 5 is also fixed by being sealed at both ends in the folded form between the main walls 3 and 4 and between their extensions, which respectively form an outwardly folded half of the narrow walls 7 and 8.
  • the lower narrow wall 6 is not shown and in fact not formed. Instead, only sufficient extensions of the main walls 3 and 4 and the narrow walls 7, 8 are provided for this, as long as the bag laid flat in the shipping is still unfilled.
  • the narrow wall 6 is first formed with a transverse central sealing seam.
  • the bag 1 in the upper narrow wall may also be completed before filling.
  • a handle (not shown), in particular in the form of a flat strip or film strip and be folded. It can also be there weakening lines 25,26 for easier tearing of the packaging between the dividing planes, so be attached to the packaging parts.
