Abstract: An improved watering device comprises a cap member including a fastening portion provided at the upper side thereof for screwing with a container, and including a hollow tapered insertion element couplingly disposed at the lower side thereof and communicating with the fastening portion for forming a water passageway therein, and the cap member containing an air flowing duct extending in the air venting end of the cap member and having an air admitting end formed at the outer portion thereof for screwing with a rotating knob, wherein the air admitting end of the air flowing duct includes a tapered outer thread portion attached thereon so that as screwing with the rotating knob, an air admitting sacs between the inner and outer thread portions may be formed, thereby the outside air may flow into the air flowing duct, any by using the control member, the outflow amount of fluid may be stably regulated.

Abstract: Top via pattern for a bond pad structure has at least one first via group and at least one second via group adjacent to each other. The first via group has at least two line vias extending in a first direction. The second via group has at least two line vias extending in a second direction different from said first direction. The line via of the first via group does not cross the line via of the second via group.

Abstract: A watering device comprises a watering container, a cap, a control knob, and an air tube. The cap is fastened with the water container such that an air inlet of the cap and a channel of a tapered projection of the cap are in communication with the hollow interior of the water container. The tapered projection of the cap is provided with at least one water discharging hole in communication with the air inlet of the cap. The control knob is rotatably fastened with an outer end of the air inlet such that the control knob can be turned to block the air inlet. The air tube is fastened at one end with an inner end of the air inlet such that other end of the air tube is extended into the hollow interior of the water container.
