Abstract

Abstract A liquid pouring device comprises a conduit, a screwed cap, a partition plate, a tension spring, a valve collar and a funnel. The partition plate inserted in the conduit divides the conduit into one long channel and one short channel for the liquid and air to flow. The screwed cap with a gasket is fixed to the top end of the conduit for screwing on the container from which the liquid is to be poured. The stopper is fixed to the lower end of the partition plate and the valve collar is slidably fitted over the small part of the conduit. The tension spring is fitted over the conduit between the valve collar and the flange of the conduit. The funnel is connected with the valve collar. Thus, the liquid can be poured from the liquid container into an empty container smoothly and safely.
