    Abstract: A container is adapted to contain a liquid and separate solids from the liquid. The container includes a body, a cover unit, and a ring-shaped filter plate. The body defines a receiving space adapted for receiving the liquid therein, and has a top opening and a pouring opening in spatial communication with the receiving space. The cover unit includes a cover member removably covering the top opening, and an insert member extending downwardly from the cover member into the receiving space. The filter plate is disposed in the receiving space at a position below the pouring opening, is sleeved on one of a bottom portion of the cover member and a top portion of the insert member, and is adapted for filtering out the solids during passage of the liquid therethrough.

    Abstract: A sealing cover with a two-way embedding buckle mechanism includes an upper cover member, a lower cover member, a fastener, an elastic element and a handle member. The fastener has two embedded buckle channels corresponding to each other, each includes a sliding path, a first embedding port and a second embedding port. The first and second embedding ports are formed on two ends of the sliding path respectively. The elastic element is elastically clamped between the upper and lower cover members. The handle member includes a knob handle and two support arms, and each support arm has a shaft, and each shaft selectively enters one of the first and second embedding ports and is capable of moving in each sliding path. This arrangement may improve the convenience of assembling and disassembling.
