[0007] A sealed anti-overflow plastic cup includes a plastic cup body. A cup lid is threadedly connected to the upper surface of the plastic cup body. A water storage inner cavity is opened on the inner side wall of the plastic cup body. An overflow water port is opened through the top of the inner wall of the plastic cup body and extends into the water storage inner cavity. An arc-shaped groove is opened through the upper surface of the plastic cup body near the overflow water port. A limiting collar is movably installed at the top of the outer surface of the plastic cup body. The bottom end of the inner wall of the limiting collar extends into the arc-shaped groove and is welded with a connecting piece. The bottom end of the connecting piece is placed inside the water storage inner cavity and is welded with a water-blocking sealing block. A drainage assembly is further provided at the bottom inside the water storage inner cavity for draining the overflowed liquid in the plastic cup body.

[0008] Preferably, the drainage assembly includes a drainage hole opened at the bottom on one side of the inner wall of the water storage inner cavity, and an elastic sealing plug is clamped inside the drainage hole.

[0009] Preferably, a second sealing pad is fixedly installed on the upper surface of the limiting collar, and the lower bottom surface of the cup lid is mutually attached to the upper surface of the second sealing pad.

[0010] Preferably, a first sealing gasket is clamped at the top edge of the inner wall of the cup cover. The upper surface of the plastic cup body extends into the cup cover, and the upper surface of the plastic cup body abuts against the first sealing gasket.

[0011] Preferably, the area of one side of the inner wall of the water-blocking seal block is larger than the cross-sectional area of the opening of the inner wall of the overflow port. The two sides of the outer surface of the overflow port are respectively attached to the two sides of the inner wall of the water storage cavity, and the water storage cavity and the water-blocking seal block are engaged with each other.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] The opening of the plastic cup body is covered and sealed by the cup cover. When the plastic cup body is filled with liquid exceeding the overflow port, the limiting collar is rotated to move the water-blocking seal block to open the overflow port, so that the liquid in the plastic cup body exceeding the overflow safety overflows into the water storage cavity. When the cup cover is opened, the limiting collar is rotated to seal the overflow port by the water-blocking seal block, keeping the liquid level in the plastic cup body below the overflow port. Compared with the prior art, the present solution has the effect of facilitating the diversion of the overfilled liquid in the plastic cup body, improving the convenience of the plastic cup body during use, and solving the problem that the plastic cup body overflows to the external environment due to overfilling of the liquid, causing pollution.
