Description

Liquid funnel to prevent overfilling of a container

STATE OF THE ART

Funnels of the usual design, which can be used to fill liquids, in particular operating materials, into tanks or other containers, have a grip tab for holding the funnel when filling and a nozzle that tapers downwards, on the outside of which a groove is pressed in for ventilation.

PROBLEM

The invention specified in claim 1 is based on the problem of creating a funnel that takes up overfilled liquids and at the same time brings about a pressure equalization in the container to be filled and makes it possible to (re-)fill the overfilled amount of liquid into another container without spilling or loss.

SOLUTION

This problem is solved with the features listed in claim 1.

BENEFITS ACHIEVED

The invention achieves that

the overflow of the container to be filled is prevented because overfilled liquids are collected in the funnel. In particular, when refilling the fuel tanks of pleasure boats and aircraft, the funnel described can be used to prevent water or soil contamination;

overfilled liquids collected in the funnel can be returned to another container, e.g. a reserve canister or disposal container for operating materials, without loss;

Due to the ventilation of the container via the piston rod of the funnel, overpressure of the container's own ventilation cannot occur.

it is easy to operate by hand, the funnel can be adapted to the filling openings of the containers using an adapter for different closure systems and makes complex installations that are supposed to have the same effect unnecessary.

the funnel can be made from different materials for the respective application profile and can therefore be offered on the market at different prices.

FURTHER DEVELOPMENT OF THE INVENTION

An advantageous embodiment of the invention is specified in claim 2.

Claims (2)

Hans Weisniann, Dr: R<Jbert fillet,.: :.;. Annex to the application for registration of the brewery on 29 January 1994 -1- Protection claims MAIN CLAIM 1. Liquid funnel
characterized, that the thread or other closure system on the lower part, with nozzle and seal, can be used to create a firm and tight connection with the closed container for holding liquids, for example a fuel tank, that in the middle of the funnel housing below the mounting edge there is a cross-beam with guide for the piston rod with a groove for receiving the locking clip , that a piston rod with central ventilation, palm grip with pressure compensation and drip edge and locking piston with sealing ring and gripped hose nipple with flexible hose line and guide piece can be pulled upwards to the stop in an opening position and is held in this position by a locking clip, and that the piston rod can be pushed into a lower position and then closes the tank/container opening and prevents the liquid from running out of the funnel, whereby pressure equalization is achieved via the hose, the piston rod and the openings in the palm grip.

Annex to the application for registration of the registration form dated 29 January 1994 -2- SUB-CLAIM 2. Liquid funnel according to claim 1
characterized, that the funnel with the device described can be made in any size and from different materials (e.g. metal, plastic) and can be used for operating materials and other liquids, that the nozzle of the funnel can be adapted to different container closure systems using an adapter, that after the piston rod is pressed down, the sealing effect in the funnel neck via the closure piston with seal means that the overfilled liquid remains in the funnel housing and can then be refilled into another container without loss. that operating fluid escaping from the central ventilation drips back into the funnel via the drip ring on the palm grip and cannot get outside the container.
