Disclosed is an ophthalmic lens storage container comprising: a container body including a lens storage portion having a cavity for storing a lens and a preserving solution, and a flange surrounding the cavity; and a cover sheet stripably sealed to the flange in a sealing zone that extends around the cavity to thereby fluid-tightly seal the lens storage portion. The flange of said container body includes an insulating portion located radially outward of an open-end peripheral portion of the cavity, extending circumferentially and includes a shoulder surface that extends in a first direction opposite to a second direction along which the cavity is exposed, and the sealing zone is located radially outward of the insulating portion of the flange.

1. An ophthalmic lens storage container comprising:a container body including a lens storage portion having a cavity for storing an ophthalmic lens and a preserving solution, and a flange extending radially outward around an open-end peripheral portion of said cavity; and a cover sheet superposed on said container body for covering an opening of said cavity and being stripably sealed to said flange in a sealing zone that extends around said open-end peripheral portion of said cavity over an entire circumference of said cavity, to thereby fluid-tightly seal said lens storage portion; wherein said flange of said container body includes an insulating portion located radially outward of said open-end peripheral portion of said cavity so as to extend circumferentially, said insulating portion has a shoulder surface that extends in a first direction opposite to a second direction along which said cavity is exposed, wherein said sealing zone to which said cover sheet is stripably sealed to said flange portion is exclusively located radially outward of said insulating portion of said flange, wherein and inner surface of said cavity includes a central portion and an open-end side portion that serves as a removal-guide surface whose radius of curvature is made different from that of said central portion, and wherein said removal-guide surface is smoothly connected to a plane surface extending in a direction perpendicular to said second direction, and being located axially upward of said sealing zone via said shoulder surface. 2. An ophthalmic lens storage container according to claim 1, wherein said flange of said container body further includes a lower surface spaced away from said opening of said cavity in said first direction, said lower surface serving for providing said sealing zone.3. An ophthalmic lens storage container according to claim 1, wherein said insulating portion is constituted by a groove open in a front surface in which said cavity is open, and said shoulder surface is constituted by an inner circumferential wall surface of said groove.4. An ophthalmic lens storage container according to claim 1, wherein said insulating portion, which is located radially outward of said open-end peripheral portion of said cavity, continuously extends over an entire circumference of said cavity.5. An ophthalmic lens storage container according to claim 1, wherein said open-end peripheral portion of said cavity extends circumferentially with an outwardly curved shape in cross section.6. An ophthalmic lens storage container according to claim 1, wherein said removal-guide surface consists of a plurality of segments having different radius of curvatures and being connected together in said second direction.7. An ophthalmic lens storage container according to claim 1, wherein said removal-guide surface continuously extends over an entire circumference of said cavity.8. An ophthalmic lens storage container according to claim 7, wherein said removal-guide surface has an outwardly curved shape in cross section.9. An ophthalmic lens storage container according to claim 8, wherein said radius of curvature of said removal-guide surface is partially made larger at a circumferential portion as an intended lens removal portion.10. An ophthalmic lens storage container according to claim 9, wherein said flange has a rectangular shape and said intended lens removal portion is approximately directed to a diagonal direction of said flange.11. An ophthalmic lens storage container according to claim 1, wherein said insulating portion is located radially outward of said open-end peripheral portion of said cavity with a spacing in between, said spacing including a plane surface.12. An ophthalmic lens storage container according to claim 1, wherein at least one circumferential portion of said sealing zone protrudes radially outward with a beak-like shape to thereby provide a beak-like portion.13. An ophthalmic lens storage container according to claim 1, wherein at least one circumferential portion of said sealing zone extends radially outward to thereby provide a seal-retaining portion that allows said cover sheet, which is partially stripped from the flange to expose said cavity substantially entirely, to be retained in said flange.14. An ophthalmic lens storage container according to claim 12, wherein said sealing zone extends radially outward to provide a seal-retaining portion at another circumferential portion that is opposed to said at least one circumferential portion where said beak-like portion is provided with said cavity interposed therebetween, said seal-retaining portion allows said cover sheet, which is partially stripped from said flange including said beak-like portion of said sealing zone to expose substantially entirely said cavity, to be retained in said flange.15. An ophthalmic lens storage container according to claim 14, wherein said sealing zone includes a pair of said beak-like portions formed at respective circumferential positions thereof opposed to each other with said cavity interposed therebetween, and one of said pair of beak-like portion serves as said seal-retaining portion.16. An ophthalmic lens storage container according to claim 1, wherein a width dimension of said sealing zone varies in a circumferential direction thereof so that said width dimension is maximized at two circumferential positions that are opposed to each other in one direction perpendicular to a direction along which said cover sheet is intended to be stripped off.17. An ophthalmic lens storage container according to claim 1, wherein said flange is provided with at least one cutout in a periphery thereof.18. An ophthalmic lens storage container according to claim 1, wherein said flange includes a peripheral wall that extends outward from a bottom of said lens storage portion in said first direction to be served as a support member.
