Abstract
In a hogshead formed from convolutely wound paper tubes that are cut into complemental halves, reinforcing staves are adhered to the marginal cut edges of each tube moiety, and hinge members, comprising generally two part hinges, are secured to each stave with their turned ends embracing against the remote side edges of each stave to insure structural integrity for the hogshead particularly while the tobacco is being prized; the upper and lower interior edges of each tube half portion includes liners that are rigidly fastened thereto, while end closures having ring members that are arranged concentrically within the liners are fitted within the assembled hogshead to provide it with closure. The staves may be formed from metal that is pressed to expose a series of pointed spikes that may insure the retention of each stave to the paperboard tube, and the hinge means may be designed to provide their partial insertion within said tubes halves to further insure the structural integrity of the hogshead during usage.
