Abstract
An easy-open, spiral wound container for packaging refrigerated dough products includes a spirally wound fibrous core layer, forming an unbonded spiral butt joint. The container also includes an inner liner layer and an outer label layer, each having a seam. The outer label layer is weakened along the butt joint to facilitate opening of the container. An end closure member seals an end of the container.
Claims3
A no-peel, easy-open composite cylindrical container for refrigerated dough products, comprising:
- a container body comprising:
- a fibrous tubular core including a longitudinal butt joint;
- an inner liner adhesively bonded to an inner surface of the fibrous core, the inner liner having a longitudinal seam located proximate the butt joint;
- an outer label layer adhesively bonded to an outer surface of the fibrous core;
- means for weakening the outer label layer located substantially in radial registry with the butt joint while providing sufficient strength to resist internal container pressure and opens upon application of external pressure along the outer surface of the container along the butt joint without removal of a portion of the container body prior to opening;
- and
- at least one end member for sealing the container, wherein the end member is suitable for vacuum packaging;
- and further comprising a second end member suitable for vacuum packaging.
A no-peel, easy-open composite cylindrical container for refrigerated dough products, comprising:
- a container body comprising:
- a fibrous tubular core including a longitudinal butt joint;
- an inner liner adhesively bonded to an inner surface of the fibrous core, the inner liner having a longitudinal seam located proximate the butt joint;
- an outer label layer adhesively bonded to an outer surface of the fibrous core comprising a polymer film, wherein the polymer film is biaxially oriented;
- means for weakening the outer label layer located substantially in radial registry with the butt joint while providing sufficient strength to resist internal container pressure and opens upon application of external pressure along the outer surface of the container along the butt joint without removal of a portion of the container body prior to opening;
- and
- at least one end member for sealing the container.
