Patent ID: 7727457

Claim:
A method for manufacturing a plastic lacrosse head including a frame element having a base portion, a scoop portion located opposite the base portion, a pair of opposing sidewall portions generally extending between the base portion and the scoop portion, and a projection extending rearwardly from the base portion for engaging a lacrosse handle, comprising: defining a mold cavity that is sized and shaped to meet the dimensions of the plastic lacrosse head, such that the resultant molded head includes the open frame, which includes an upper portion defining a ball receiving area and a lower portion defining a ball retention area; determining at least two separate and distinct locations in an interior of the plastic lacrosse head where at least two substantially hollow cavities having a generally predetermined size and shape will be disposed; injecting into said mold cavity a plastic material that is slightly less than a volume of said cavity to form the plastic lacrosse head; and injecting a fluid into said plastic material in the mold cavity and directing the fluid generally into the at least two locations to form said substantially hollow cavities, wherein said at least two locations include at least one of the pair of opposing sidewall portions, the base portion, and the scoop portion, wherein the cavities are adapted to reduce the weight of the head without significantly impacting the strength and performance of the head, wherein the remaining portions of the sidewall portions, the base portion and the scoop portion are solid and non-hollow.
