ABSTRACT:
The following specification discloses a container such as a box, packing or shipping container for items that are to be maintained in a vapor proof environment. The container is made out of a sheetlike material, such as plastic derived from one of the olefin family of plastics. It is formed with bumpers, guards, and reinforcing and expanded portions of the case for protection and reinforcement thereof. The sealing and closure means comprise a pair of channel members that are secured over the edge of the walls of the container. One of the channel members provides an elongated depressed seat for an elastomeric seal therein, and the second channel member provides a mating tongue that seats against the elastomeric seal. Both of the channel members are hinged, latched or clamped together with the edge regions of the container walls lying within the channels. The channels have barbs or tangs which impinge against the container wall portion. The barbs are on opposite channel walls and are offset against said wall portion. This provides a bending moment to the container wall and a sealing of the wall portion against the barbs or tangs. The container wall section is further sealed in the channel by means of a non-hardening sealant.
