Abstract
An injection molded product formed from an inner layer, or substrate, to which an aesthetic IMD layer is bonded during a first injection molding process, leaving a portion of the substrate exposed about the perimeter(s) of the substrate. A transparent outer layer, or overmold, is then injection molded over the top of the IMD layer and substrate, bonding substantially to the IMD layer and to the substrate where it remains exposed following the first injection molding. The process of forming a product through the disclosed two-step injection molding process creates a customizable, aesthetic product with an aesthetic IMD layer completely encapsulated between the substrate and a clear overmold in such a way to protect the IMD layer from the environment in which the product is used.
Claims11
A polymer sealed in-mold decoration comprising:
- an in-mold decoration layer having an in-mold decoration surface area;
- a substrate having a substrate surface area larger than said in-mold decoration surface area and an external perimeter, said substrate is bonded to said in-mold decoration layer, thereby forming an exposed external portion of said substrate extending between said in-mold decoration and said external perimeter of said substrate;
- a first molded layer attached to said in-mold decoration layer with an exposed portion of said first molded layer extending beyond said in-mold decoration layer;
- a second molded layer covering said in-mold decoration layer and attached to said exposed portion of said first molded layer;
- wherein said in-mold decoration layer is sealed between said first molded layer and said second molded layer.
A polymer sealed in-mold decoration comprising:
- an in-mold decoration layer;
- a first molded layer attached to said in-mold decoration layer with an exposed external portion of said first molded layer extending past said in mold-decoration, formed by a first injection of a substrate material onto and past said in-mold decoration layer;
- a second molded layer attached to said in-mold decoration layer and said exposed external portion of said first molded layer, formed by an injection of an overmold material onto said in-mold decoration layer and said exposed external portion of said first molded layer;
- and
- wherein said in-mold decoration layer is attached to said first molded layer and said second molded layer and is sealed between said first molded layer and said second molded layer.
A polymer sealed in-mold decoration comprising:
- an in-mold decoration having an in-mold decoration surface area;
- a substrate having a substrate surface area larger than said substrate surface area and an external perimeter, said substrate is bonded to said in-mold decoration, thereby forming an exposed external portion of said substrate extending between said in-mold decoration and said external perimeter of said substrate;
- an overmold bonded to said in-mold decoration and said exposed external portion of said substrate;
- wherein said in-mold decoration is bonded to said substrate and said overmold and is sealed between said substrate and said overmold, and
- wherein said substrate, said in-mold decoration, and said overmold form a single seamless unitary part.
