PURPOSE: A funnel is provided to conveniently inject liquid into a container having an open top because air in the container is exhausted to the outside when the liquid is injected. CONSTITUTION: A funnel is composed of a conical guide part (10) and a cylindrical injection part (20). The guide part has an upper hole (11) in which liquid is injected. The injection part is located under the guide part, and a lower hole is formed on the bottom thereof. A groove is formed on the circumference of the guide part and the injection part in a vertical direction. An opening and closing plate is installed in the lower hole through a hinge part. The hinge part is integrally connected to the bottom end of the injection part and the opening and closing plate. A connection rope is connected to one end of the opening and closing plate and is installed in the groove formed on the circumference of the guide part and the injection part. |
