Abstract
A tubular packaging container includes a body (10) which includes a peripheral wall (34) defining top and bottom openings, at least one of which is closed by an end member. The body is formed from at least two panels (20, 30) of a suitable card material cut from flat stock. The panels are secured together in face-to-face relationship by adhesive (32) distributed across the mutually contacting faces thereof. The panels are then curved to the required shape to form a tube with marginal portions (31) of at least one of the panels secured together in overlapping relationship.
