Definitions

  • Tube use of a plastic bag and method of making a tube
  • the invention relates to a tube and the use of a plastic bag with a plastic film material which forms an end wall and two side walls of the tube.
  • Resealable bags for holding liquid or pasty goods are usually made of plastic material with very thin walls. These bags are therefore very unstable and flexible. Therefore, they are not suitable as tubes.
  • the primary object of the invention is to design a tube in such a way that the risk of tipping over as described above is reduced when the tube is placed on the closure cap as indicated.
  • the film material is advantageously a laminate which has at least a 60 to 200 ⁇ m thick inner sealing layer made of polyolefin and a 10 to 25 ⁇ m thick outer layer made of polyester, the strip-shaped side edge sections each having a width of at least 6.5% of the total width of the side walls, however, they are at least 4 mm wide in any case.
  • the side walls are two stripes
  • Fig. 1 is a side view of a bag tube
  • Fig. 2 is a section along the line 2-2 in Fig. 1 and
  • Fig. 3 on a larger scale a cross section through the film material of the bag tube, approximately in the area of circle A in Fig. 2.
  • the bag tube shown in Figs. 1 and 2 has two side walls 11 and 12 and an end wall 13, all of one Pieces of film material are formed from plastic.
  • the film material is preferably thin, light and flexible. According to the invention, it is above all a laminate with an inner sealing layer 14 (FIG. 3), whose thickness d L is 60 to 200 ⁇ m, and with an outer layer 15, whose thickness d 2 is 10 to 25 ⁇ m.
  • the inner sealing layer 14 consists of polyolefin, preferably polypropylene, polyethylene or a copolymer. It can also consist of several layers of different polyolefins.
  • the outer layer 15 consists of polyester, preferably polyethylene terephthalate or polyethylene naphthalate or a copolymer of, for example, 90% to 95% PET and 10% to 5% PEN.
  • a barrier layer 16 can expediently be arranged between the inner sealing layer 14 and the outer layer 15.
  • the barrier layer 16 can consist of aluminum with a thickness d 3 of 7 to 12 ⁇ m or of para-aramid (in particular "Kevlar®").
  • the two side walls 11 and 12 are connected to one another in a surface-tight manner along two strip-shaped side edge sections 17 and 18 and along an end edge section 19, in particular welded.
  • the width B of the side walls 11, 12 is approximately 100 mm in the exemplary embodiment.
  • the side edge sections 17 and 18 each have a width b, which in the exemplary embodiment is approximately 7%, but generally approximately 6.5% to 10% of the width B of the side walls 11, 12.
  • the width b is at least 4 mm.
  • the width b of the weld seams Both side edge sections 17, 18 optimally ensure a substantial stiffening of the tube body.
  • a shoulder piece is fastened to the end wall 13 and has a closable opening in the form of an outlet connector 20.

Abstract

Une paroi frontale (13) et deux parois latérales (12) du tube ou de la poche plastique utilisée comme tube, sont constituées d'un laminat comportant une couche de scellement interne en polyoléfine d'une épaisseur de 60 à 200 mu m et une couche externe en polyester d'une épaisseur de 10 à 25 mu m. Les parois latérales (12) sont assemblées de façon plate par leurs deux bordures (17, 18) en forme de bandes de telle façon que les extrémités de délimitation internes opposées dans la zone de la paroi frontale (13) soient repliées l'une vers l'autre vers l'intérieur. Un épaulement (20, 22, 23, 24) présente une ouverture refermable ayant la forme d'un raccord de sortie (20) et un flasque (22) relié à la paroi frontale (13). Les bordures latérales (17, 18) en forme de bandes ont une largeur (b) au mois égale à 6,5 % de la largeur totale (B) des parois latérales (12). Cette conception du tube permet de réduire le risque que les parois latérales (12) ne s'affaissent et que le tube ne se renverse lorsque le tube dont le raccord de sortie (20) est fermé par un bouchon (21), est posé à l'envers sur ce bouchon.
