A moisture-tight, re-sealable container comprising: a. a body having a generally tubular sidewall with first and second axially opposed ends, a base, and a dispensing opening axially spaced from the base and at least adjacent to the second end; b. an interior space disposed generally within the sidewall and at least generally between the base and the dispensing opening; c. the generally tubular sidewall having a cross-section having a major diameter and a minor diameter, wherein the ratio between the major diameter and the minor diameter of the sidewall cross-section is a value between 1.1: 1 and 10: 1, inclusive; d. a non-round body sealing surface located on the body and disposed about the dispensing opening, the body sealing surface having a major diameter and a minor diameter, wherein the ratio between the major diameter and the minor diameter of the body sealing surface is a value between 1.1: 1 and 10: 1, inclusive; e. a lid configured to seat on the body; f. a lid sealing surface located on the lid; g. the body sealing surface and the lid sealing surface being configured to mate to form a seal between the lid and the body when the lid is seated on the body; and h. the lid and lid sealing surface at least substantially closing the dispensing opening and isolating the interior space from ambient conditions; i. the container having a moisture ingress rate of 100-1000 micrograms per day, at 80% relative humidity and 22.2°C, and j. comprising a reinforcement (22, 162, 184, 206) stiffening the body sealing surface against deflection along an axis defined by the minor diameter when the lid is seated on the body, and characterized in that, the interior space is defined at least in part by the reinforcement (22, 162, 184, 206) stiffening the container against deflection along the minor axis and in which the reinforcement is an insert assembled with the container, or in which the reinforcement is defined at least in part by a liner, or in which the reinforcement comprises a spline within the interior space. a. a body having a generally tubular sidewall with first and second axially opposed ends, a base, and a dispensing opening axially spaced from the base and at least adjacent to the second end; b. an interior space disposed generally within the sidewall and at least generally between the base and the dispensing opening; c. the generally tubular sidewall having a cross-section having a major diameter and a minor diameter, wherein the ratio between the major diameter and the minor diameter of the sidewall cross-section is a value between 1.1: 1 and 10: 1, inclusive; d. a non-round body sealing surface located on the body and disposed about the dispensing opening, the body sealing surface having a major diameter and a minor diameter, wherein the ratio between the major diameter and the minor diameter of the body sealing surface is a value between 1.1: 1 and 10: 1, inclusive; e. a lid configured to seat on the body; f. a lid sealing surface located on the lid; g. the body sealing surface and the lid sealing surface being configured to mate to form a seal between the lid and the body when the lid is seated on the body; and h. the lid and lid sealing surface at least substantially closing the dispensing opening and isolating the interior space from ambient conditions; i. the container having a moisture ingress rate of 100-1000 micrograms per day, at 80% relative humidity and 22.2°C, and j. comprising a reinforcement (22, 162, 184, 206) stiffening the body sealing surface against deflection along an axis defined by the minor diameter when the lid is seated on the body, and characterized in that,
