Utility model application "Air inlet pipe ¹ Ref.: G 93 20 054.4

Description and representation of the invention:

Figure 1 shows a liquid dispenser with an air inlet pipe. All types of liquids - whether thin or thick - can be dosed 100%.

Bottles or canisters without the air inlet tube I invented cause residues that can pollute the environment because you cannot determine the desired dosage precisely. But not with the liquid dispenser, because it is equipped with an air inlet tube I invented which I describe below.

It is important that when you press the button and place it vertically, liquid flows evenly from the bottle or canister into the desired object. Once the desired object is filled with liquid, you let go of the button and no residue will be left behind, as no more suction can occur.

Bottles or canisters into which I insert a ventilation valve, which opens a liquid outlet by pressing a button in conjunction with a cord, which I then attach to the top of the flap and to the sheet metal of the lower part. A 0.5 mm thick spring pushes the flap upwards and thus keeps the outlet opening sealed.

State of the art:

Containers of conventional design are only equipped with a screw cap

which do not always seal completely. For example, when refilling *.···* exact dosing is not guaranteed, as "····

the liquid flows out quickly and bubbling and thus the environ- j ;

can be widely polluted. J ! &Idigr;

Issue: *.!··*

The invention is based on the problem of precisely dosing liquids and dispensing them without bubbling.

Invention:

I solve this problem as follows: My invention enables clean, controlled and bubbling-free dispensing of liquids, such as engine oil, fabric softener or acids, which means that the environment is no longer polluted. Since the container can be refilled again and again, it can be used an infinite number of times.

Claims (1)

Protection claims: Figure 1 shows the section of the filling and ventilation mechanism.·.. _# Figure 2 View of Figure 1. ·..·.* At the end of a plastic tube (7) there is a conical rubber plug (13) for opening and closing, which allows pressure equalization in the container. .****· This process is operated by a cord (2) which has a push button (1) at the upper end and which opens or closes the closure flap (11). This closure flap, which is made of plastic with an acid and oil resistant rubber coating, is attached to part 6, which is also made of resistant plastic, by means of two eyelets and a spring (14) which press on the closure flap and a steel pin (12). Part 6 contains two holes, one of which is used to attach the closure flap and the other to press the ventilation mechanism firmly into. In the narrowed plastic tube there is a spiral spring (3) which rests on this narrowed plastic tube. This spiral spring is connected to the jet wire (9), with a washer being attached to the cord via the spiral spring. This cord is fed into the plastic tube, where there is a thread at the bottom end to secure the cone plug. This is secured with self-locking nuts (15).
