Spiral wound cylindrical container - has label and reinforcing strips removable separately for complete opening in two stages

The spiral-wound cylindrical container is for opening in two stages, having separate strip or label sections and reinforcing sections, and is for packing fresh doughy products mixed with a motive substance. It comprises a strip of stiffening material (2) wound in a spiral so that the edges butt together ( 7), and to which a flexible internal cladding strip (5) is attached. a tear-off reinforcing strip (6) is glued along the join (7). a removable label or strip attached to the outside of the stiffening strip, but not to the reinforcing strip or the parts of the stiffening strip adjacent to it. A collar section (3) fits closely inside one end of the container, and near this label or removable strip is not secured to the stiffening strip, thus forming a tear-off lug for the first stage of opening, without removal of the reinforcing strip. Other lugs are attached to the latter, for its removal during the second stage, this weakening the join (7) by at least 20%. This allows the join to be open-opened over its entire length for removal of the contents.
