<p>An apparatus for packaging a series of potentially odorous objects in individual packages along a length of flexible material from which odour can escape after a delay by osmotic action laterally through said tubing. Each package S, T, U, when formed, is automatically arrested by a clamping unit B to enable the tubing leading to the package to be twisted to close that package prior to being thrust further to enable a following package to be so arrested. A collector bag (7) is provided to receive each package whereby all packages in a length thereof can be removed in the bag when sealed, the bag being made of material inhibiting any osmotic action causing odour to escape from the bag.</p> |
