Abstract
Packages, systems, and methods of the present disclosure are generally directed to the use of side gating in injection molding to form packaging for contact lenses. As compared to gating along a top surface of a contact lens package, the use of a side gate in injection molding to form a package for contact lenses may significantly reduce the time required to cool plastic in the injection mold, thus offering potential to reduce the overall cycle time for the injection molding process and increase fabrication throughput of the package.
Claims10
A package for a contact lens, the package comprising:
- a base including a first surface and a second surface, the first surface opposite the second surface, the first surface and the second surface forming a reservoir, the first surface concave along the reservoir and defining a recess, the second surface convex along the reservoir, the first surface forming a rim region circumscribing the recess, and the rim region defining a plane;
- one or more walls, at least one of the one or more walls including a wipe surface and at least one draft surface, the at least one draft surface extending from the base in at least one direction oblique to the plane defined by the rim region, and the wipe surface perpendicular to the plane defined by the rim region;
- and
- wherein the wipe surface is located on the same wall as the at least one draft surface.
