Claims6
A molded plastic bottle carrying case comprising:
- at least four upright plastic solid Walls;
- a bottom wall attached to said at least four upright plastic solid walls;
- at least one handle defining an opening integrally formed with a first wall of said at least four upright plastic solid walls, said opening defining an upper region located between said opening and an upper edge of said first wall of said at least four upright plastic solid walls and a lower region located between said opening and a lower edge of said first wall of said at least four upright plastic solid walls;
- and
- a hollow gas injected reinforcing channel only in said upper region of said first wall of said at least four upright plastic solid walls, whereby said hollow gas injected reinforcing channel provides substantial reinforcement of said at least one handle thereby preventing said at least one handle from tearing out of said first wall of said at least four upright plastic solid walls when lifting said plastic bottle case by said at least one handle.
