 B31B

Note(s)

  1. In this subclass, envelopes or bags are regarded as being essentially flexible containers, the final shape of which is determined by their contents.
  2. In this subclass, the following expression is used with the meaning indicated:
    • "boxes or cartons" includes bags formed similarly to cartons, trays with upstanding side-walls, barrels, tubes and cups, other than articles formed by winding.
  3. In groups B31B 3/00-B31B 41/00, it is permitted to classify inventions in subgroups which have not been printed in the Classification. The subgroups which may be used for this purpose correspond exactly in wording, hierarchical position and subgroup numbering to the relevant subgroups of group B31B 1/00. For example, a machinery specifically for folding sheets around mandrels could be classified either in group B31B 9/26 (which is printed) or in group B 31 B 9/28 (which is not printed).
