ABSTRACT:
A transparent capsule is manufactured by using a lower die case having a substantially semi-spherical inner surface and an upper die cast having a substantially semi-spherical outer surface. The radius of the upper die cast is slightly smaller than that of the lower die cast. Transparent resin in the space between the lower die cast and said upper die cast is uniformly and gradually heated and then cooled in order to harden the transparent resin.
Thereafter, the upper die cast is separated from the lower die cast and the transparent resin formed in the shape of a sphere is removed from the die casts.
