Abstract

An injection molded product may include a corner shingle resembling a single course of tiles that differ in size. The corner shingle may be a semi-crystalline thermoplastic and having a wood grain direction. Streaks may be formed in the corner shingle that are substantially parallel to the wood grain direction. The streaks may extend through an interior of the corner shingle and appear as contrasting streaks on an exterior of the corner shingle to form a variegated wood grain appearance. In addition, an injection molded vestige may be formed in the corner shingle. The injection molded vestige may be located adjacent a perimeter of the corner shingle, and may comprise the location at which material entered an injection mold through a gate.

First claim

What is claimed is:

1. An injection molded product, comprising:
a corner shingle resembling a single course of tiles that differ in size, the corner shingle comprising a semi-crystalline thermoplastic and having a wood grain direction;
streaks in the corner shingle that are substantially parallel to the wood grain direction;
the streaks extend through an interior of the corner shingle and appear as contrasting streaks on an exterior of the corner shingle to form a variegated wood grain appearance; and
an injection molded vestige in the corner shingle, the injection molded vestige is located adjacent to a perimeter of the corner shingle, and the injection molded vestige comprises the location at which material entered an injection mold through a gate.

2. The injection molded product of claim 1 , wherein the corner shingle is notched such that upper outer corners of the tiles are removed.

3. The injection molded product of claim 1 , wherein the corner shingle comprises only two tiles that are substantially orthogonal.

4. The injection molded product of claim 1 , wherein each tile comprises a headlap and an exposed portion below the headlap, the headlap further comprises a pair of flow runners that intersect at the injection molded vestige at the perimeter.

5. The injection molded product of claim 1 , wherein each tile has a different texture.

6. The injection molded product of claim 1 , wherein the corner shingle has a front or cavity side, and a back or core side, and both the front and back are textured, rather than smooth or flat.

7. An injection molded product, comprising:
a corner shingle, comprising:
a headlap;
an exposed portion below the headlap;
an injection molded vestige formed in the headlap;
at least a pair of flow runners within the headlap, wherein the pair flow runners intersect at the injection molded vestige; and

wherein the corner shingle resembles a single course of tiles that differ in size, the corner shingle comprising a semi-crystalline thermoplastic and having a wood grain direction with streaks in the corner shingle that are substantially parallel to the wood grain direction and extend through an interior of the corner shingle and appear as contrasting streaks on an exterior of the corner shingle to form a variegated wood grain appearance.
