Abstract
A moisture tight container (100, 300) includes a container body (101, 301) and a lid (101, 120, 320) preferably linked to the body (101, 301) by a hinge (140, 340). The body (101, 301) and lid (101, 120, 320) include at least a first seal (462) and a second seal (464) in series to provide a moisture tight seal (460) between the body (101, 301) and the lid (101, 120, 320). The first seal (462) includes mating of thermoplastic-to-thermoplastic sealing surfaces of the body (101, 301) and lid (101, 120, 320) respectively. The second seal (464) includes mating of thermoplastic-to-elastomeric sealing surfaces of the body (101, 301) and lid (101, 120, 320), respectively, or of the lid (101, 120, 320) and body (101, 301), respectively.
