A tank for a pressure-assist toilet flush system includes a base and a cover formed of a composite material including a polymer matrix of a crystalline polymer material, with a short fiber reinforcement material having a fiber length of 0.125 inch to 0.177 inch dispersed therein at a fill ratio of 25-35%. The base has a bottom wall and a plurality of base sidewalls extending upward from the bottom wall to an upper end of the base, with an outlet defined in the bottom wall. The cover has an inlet for receiving water into the tank and includes a top wall and a plurality of cover sidewalls extending downward from the top wall to a lower end of the cover. The inlet is defined in the top wall, and the lower end of the cover is connected to the upper end of the base.

Tank for toilet flushing system and manufacturing method

A tank for a pressure-assist toilet flush system includes a base having an outlet for discharging water from the tank and a cover connected to the upper end of the base at a tongue-and-groove joint. The base has a pair of first sidewalls extending downward from the upper end of the base along a length of the base, a pair of second sidewalls extending between the first sidewalls and downward from the upper end of the base, and a bottom wall connected to the first sidewalls and the second sidewalls, with the outlet defined in the bottom wall. The base also includes first and second cross-ribs connected to the first sidewalls and each having a bridge portion extending between the first sidewalls on opposite sides of the outlet, the first and second cross-ribs each having an opening between a bottom edge of the bridge portion and the bottom wall.
