Abstract: A flow control device is provided. The flow control device includes a body including a containing space, a discharge opening fluidly communicating with the containing space, and a pair of side holes configured to be in radial correspondence with each other; a flow control member installed in the containing space and including a pair of engaging portions corresponding to the side holes; an adapter including an adapting part coupled to the body and a hitching part for being coupled to an external container; a washer coupled to the adapting part and inserted into the body for installing the flow control member in the containing space; and a handle including an operational part, and a pair of engaging ends coupled to the operational part and engaged with the engaging portions through the side holes.

Abstract: A shoelace with a shoelace fastener includes a first retaining base at an end of a first lace and/or a second retaining base at another end of the first lace, and a ratchet and an elastic clipping element are disposed in the first retaining base and the second retaining base respectively, such that the ratchet can be pressed at an end of the elastic clipping element, and the ratchet is pressed by the elastic clipping element into a normal slantingly pressed down status. When use, a fabric shoelace or a serrated plastic groove is passed into the retaining base, and ends of the ratchets are provided for clamping a surface of the fabric shoelace or plastic shoelace to facilitate adjusting the tightness of the shoelace.

Abstract: A flow control device includes a hood, a ball valve, a sealing ring, and a handle. The ball valve is movably received in an interior receiving space of the hood and the ball valve is set in sealing engagement with the sealing ring. The ball valve and the handle located outside the hood are coupled together and are thus movable in unison with each other. The ball valve defines a flow passage. The hood forms a discharge opening. When installed on an opening of any kind of container, such as a PET bottle or a glass bottle, or an outlet tube of a water tank, by rotating the handle to move the ball valve, the flow passage can be selectively set in fluid communication with the discharge opening.
