A urinal can include a body defining a front end, a rear end opposite the front end, and an internal volume. The body can include an opening fluidly coupled to the internal volume of the body and positioned at the front end of the body. The urinal can include a handle integrally formed with the body. The handle can have a free end that can extend away from the front end of the body towards the rear end of the body. The urinal can include a recess directed into a bottom end of the body. The recess can be configured to receive a second handle of a second urinal.

Systems and methods for disposable urinals

Urinal

A co-injection extrusion apparatus and method. The first extruder cooperates with a first material delivery channel for delivering a first material to a die. The second extruder cooperates with a second material delivery channel for delivering a second material to a die. A first plunger is positioned in the first material delivery channel and a second plunger is positioned in the second material delivery channel. The plungers are movable between a first position in which to the plunger is extended in a respective material delivery channel toward the die, and a second position in which the plunger is retracted in the respective material delivery channel away from the die.
