Patent ID: 7441650

Claim:
An ophthalmic lens 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 outwardly around an opening peripheral portion of the cavity and integrally formed with the lens storage portion; and a covering sheet superposed on the container body for covering an opening of the cavity, the covering sheet being strippably sealed around the entire circumference of the opening of the cavity to provide liquid tight closure to the lens storage portion, wherein a bottom inside face of the cavity is of generally concave spherical shape, with a radius of curvature rc in a diametrical direction along a vertical plane of the cavity that is greater than a radius of curvature R of a front face of the ophthalmic lens, wherein at least a portion on a circumference on an inside face of the opening of the cavity has at least one upright curving portion, with a radius of curvature re in the diametrical direction along the vertical plane that is smaller than the radius of curvature R of the front face of the ophthalmic lens, wherein a radius of curvature in the circumferential direction of the inside face of the opening of the cavity varies along the circumferential direction, giving the opening inside face of the cavity a planar shape generally resembling a heart shape, wherein the heart shape includes a constricted portion in the opening inside face of the cavity, with a radius of curvature ra of the constricted portion in the circumferential direction that is smaller than the radius of curvature R of the front face of the ophthalmic lens, wherein the heart shape includes two opposing side portions in the opening inside face of the cavity, with a radius of curvature rb of each of the two opposing side portions in the circumferential direction that is greater than the radius of curvature R of the front face of the ophthalmic lens, wherein a diameter dimension of an inscribed circle in the opening of the cavity is greater than the outside diameter dimension of the ophthalmic lens, and wherein two upright curving portions are provided at opposing portions in the inside face of the opening of the cavity, with the constricted portion of the heart shape interposed therebetween.
