The present invention relates to a funnel apparatus for filling of liquids, which comprises a funnel, a sealing means, a locking means, and a soft tube. The funnel apparatus has a fluid receiving member and a tubular member provided for carrying fluid. The latter has a passageway that has a top end portion installed with a handle, and a bottom end portion equipped with a stopper provided for blocking movement of the tubular member. The plunger rod has recessed portions patterned in a longitudinal orientation across its surface. The locking means has an assembly bore and a rim connected with a series of spokes; the assembly bore is fixedly disposed at an end of the receiving member so the plunger rod stretches over the assembly bore and can move axially thereby. The soft tube is inserted into the recessed portions on the plunger rod for providing an air exchange functionality. |

1. A funnel apparatus for filling liquid into a filling opening, comprising:
a funnel which comprises a receiving member and a tubular member extended downwardly from said receiving member for allowing liquid to flow therethrough, wherein one end of said receiving member defines a limiting portion surrounding an inner surface of said receiving member, wherein said tubular member has a passageway, a top portion, and a bottom portion, wherein said tubular member is arranged for being locked into said filling opening, wherein said passageway is configured to allow said fluid to flow into said filling opening therethrough; a locking means fixedly locked on said limiting portion, wherein said locking means comprises an assembly bore portion having a bore, a rim and a plurality of spokes extended between said assembly bore portion and said rim; a sealing means which comprises a plunger rod, a handle and a stopper, wherein said plunger rod has a plurality of recessed portions, a top end disposed with said handle, and a bottom end disposed with said stopper, wherein said tubular member of said funnel is blocked by said stopper; a connecting hub disposed with said locking means, wherein said connecting hub comprises an extended lip defined at one end of said connecting hub and a tubing defined by another end of said connecting hub, wherein said extended lip is disposed against an end of said assembly bore portion, and said tubing is attached on an inner surface of said bore of said assembly bore portion, wherein said tubing of said connecting hub allows said bottom end of said plunger rod to pass therethrough; and an elastic tube, which is made of soft material, inserted through said recessed portions of said plunger rod and said stopper for extending into said filling opening, wherein another end of said assembly bore portion defines a plurality of extended fingers, and said stopper has a circular recessed groove provided thereon, wherein when said extended fingers of said assembly bore portion are pushed into said recessed groove of said stopper, said stopper is apart from said tubular member and said passageway of said tubular member is opened, and when said stopper is pressed to detach from said assembly bore portion, said stopper is capable of blocking said passageway of said tubular member. |
