1. A moisture tight container comprising:
a body defining an interior configured for housing product, and an opening leading to the interior;
a lid that is connected to the body by a hinge, the lid being movable with respect to the body between a closed position in which the lid covers the opening and is mated to the body, and an opened position in which the lid is not mated to the body;
a plurality of seals between the body and the lid and in series when the lid is in the closed position, the plurality of seals including at least a first seal requiring an opening force to transition from the closed position to the opened position, and a second seal in combination with the first seal not requiring more than the opening force to transition from the closed position to the opened position, the first seal being formed by mating incompressible thermoplastic-to-thermoplastic sealing surfaces, the first seal including an undercut of the body relative to a central axis of the body, the second seal being formed by mating elastomer-to-thermoplastic sealing surfaces, wherein the elastomer-to-thermoplastic sealing surfaces include an elastomer, that is compressible and resilient, formed in the lid or on the body,
wherein a combination of the first and second seals in series reduces a moisture vapor ingress of the container while maintaining the opening force in a range that is ergonomically advantageous to a consumer,
wherein the elastomer is injection molded with the body and lid in a multi-shot injection molding process,
wherein the opening force is from 3 to 7 lbf (pound-force).
