Definitions

  • metal for example aluminium having a thickness of about 0,1 mm. and provide them with a tab or linger grip by means of whichl the closure or cap may be opened by being torn.
  • Sucli closures may be produced and applied without heating'and their application maybe eected merely by tightening, for instance, a wire loop around a closur placed on the neck of a bottle. When the wire loop or the like is tightened the closure is tight- I ened over the mouth and the top of the neckA of the bottle and at the same time it is drawn into the annular recess of the neck below the upper, bead thereof.
  • the present invention concerns the manufacture of a closure adapted to beremoved by tearing, which is cheaper than'such closures consist-- ing exclusively .of aluminium, for example 0.1 mm. thick, arid which consists mainly of nonmetallic material, but which may, however, be shaped and applied withoutY heating.
  • a container closure l or bottle cap having a linger grip by means of which it may be torn open consists of one or more metallic layers adhered 'to one or more nonmetallic layers, and its several layers are of such 40 thickness that the metallic layer or layers are of the or approximately the minimum thickness required to give Ythe necessary stiffness to the closure perse to allow it to be produced and applied without heating.
  • said closure 5 preferably consists for example of one or more aluminium layers, the thickness of which is between 0,02 and 0,06 mm., in combination with a cheap non-metallic material; it becomes there.

  • Such closures are however of adiierent type from a closure according to the invention for they are :glutinant or an agglutinant forming part of the non-metallic layer or layers of the material.
  • Al- 30 ternatively one ormore oi the non-metallic layers may consist of materials adhering automatically to the metal when applied, thereto, for instance the closure or material may be provided with a surface layer of a lac-like composition.
