Abstract: A blow molded container includes a main member comprising a top, a first side orthogonal to the top, a second side orthogonal to the top, an external wall, and an internal wall defining a tool cavity. A corner portion is defined as a portion of the main member and includes least a first layer and a second layer. The first layer forming at least a part of the external wall and the second layer forming at least a part of the internal wall. The first layer and the second layer are adhered together to along a predetermined pattern to form at least a first line segment and a second line segment on one of the internal wall or the external wall of the corner portion.

Abstract: A blow molded container includes a main member (20) forming a tool cavity. The main member (20) has an inner surface. The main member (20) further contains at least one corner portion (30) and at the corner portion (30), the main member (20) includes at least a first layer (40) and a second layer (42). The first layer (40) forming the inner surface, and the first layer (40) and the second layer (42) are affixed together along a predetermined pattern while being separated from each other elsewhere. The first layer (40) is formed with a first protruding part (143) along the predetermined pattern, and the second layer (42) is formed with a second protruding part (145) along the predetermined pattern. The first protruding part (143) and the second protruding part (145) are affixed together.
