ABSTRACT:
A thermoplastic case which has an interlocking bottom peripheral edging (20) with a lobe (26) on the outside surface to which a vacuum formed bottom (28) has been conformed completely enveloping the lobe creating a structural bond for fastening the two parts together. A lid edging (30) and case lid (38) are formed in the same manner completing the case. A resilient cord (46) may be added to assure the seal between the edgings and a bonding agent in the form of cement (50) or tape (52) may be employed to complete a hermetic seal for the case. Webbing (56) may optionally be added formed integrally with the edging for suspending articles within the case.
