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.

Abstract: A cardboard container of substantially rigid construction comprises a peripheral wall panel defining a hollow body, the wall panel including an in-turned flange formed along a peripheral edge thereof, the flange extending continuously along an entire length of the peripheral edge of the wall panel and being foldably and integrally connected to the wall panel by a continuous score line, the flange further having opposite ends held in abutment with one another within the hollow body such that the flange is held in a state of compression and retained within the hollow body in face-to-face engagement with the wall panel without otherwise being secured to the wall panel; and a transverse member being retained within the hollow body by the flange.

Abstract: The peripheral wall of a box is formed as a band with abutting ends (12,13) at a joint (35), the abutting ends being secured together by means of a tongue (26) which is provided at one end of the band entering into a recess (30) provided at the other end of the band. Preferably, the tongue (26) is formed as an extension of a lateral marginal portion (24) of the band-forming material which is folded over the adjacent main portion (11) thereof, and the recess (30) being defined between the folded-over marginal portion (24) and the adjacent portion (11) at the opposite end (12) of the band. Preferably also end portions (16,17) of the band are folded inwardly at the joint (35).
