MAKING PAPER ARTICLES; WORKING PAPER (making layered products not composed wholly of paper or cardboard B32B; handling thin material, e.g. sheets, webs, B65H)
 B31

Note(s)

  1. The word "paper" in this class is to be interpreted as covering material worked in a manner analogous to paper, e.g. plastic sheet materials, laminated materials or metal foils. This class does not include making articles directly from paper pulp, which is covered by D21J.
  2. This class is to be understood as restricted to adaptations or associations of handling sheets, webs, or blanks peculiar to paper-working, e.g. bag or box making, machinery. Handling sheets, webs, or blanks of wider applicability, irrespective of whether described or claimed only for paper-working machinery, is to be regarded as of a more comprehensive nature and as such classified in B65H.
 B31B
MAKING BOXES, CARTONS, ENVELOPES OR BAGS (incising, scoring, in general B26D 3/08; combined making and filling B65B)
 B31B

Note(s)

  1. In this sub-class, envelopes or bags are regarded as being essentially flexible containers, the final shape of which is determined by their contents. Boxes or cartons, on the other hand, are regarded as being essentially rigid or semi-rigid containers, the final shape of which is not determined by their contents. The term "boxes or cartons" is to be interpreted as including bags formed similarly to cartons, trays with upstanding side-walls, barrels, tubes and cups, other than articles formed by winding.
  2. If any further subdivision of any of groups B31B 3/00-B31B 41/00 becomes necessary, the new sub-groups to be provided will correspond exactly in wording and sub-group numbering to the relevant sub-groups of group B31B 1/00.
