FIELD OF THE INVENTION The present invention relates to a mating metering closure for dense materials, e.g. for dripping high viscosity creams from a container.

In everyday life such dense substances can be foods, e.g. mustard, ketchup, mayonnaise, etc., perfumes, e.g. shower gel, liquid soap, shampoo, etc., or even glue, bodies, etc. Containers known to date for such materials generally have drainage apertures which do not contain a dispensing head which would allow the delivery of eseppments. Which would be of great importance, since the containers currently in use can only be used to extract stored materials in a very wasteful way. Thus, the primary objective of the invention was economy.

For the same purpose, air inlet valves such as those described in US 2 / O02 / O1 / 2839 are used to seal bottles. the valve, like the other known closures, is made of circular cross-section and thermosetting material. Here, as with each of the prior art closures, the metering opening is subsequently cut through a separate operation step. material.

This latter disadvantage is eliminated by the closure of the metering valve of our patent application P06ÖÖ831; after installation it is closed with a cover with a sealing slot.

The neck is implanted with an elastic valve valve similar to that disclosed in U.S. Patent Application No. P0600831. Further experiments on the self-developed flexible valve have led to the idea that in order to be able to easily open the valve numbers defined by the gaps even under reduced pressure, I have to weaken the line of the valve wings.

Thus, our aim was to provide a closure which, while eliminating the disadvantages of known similar solutions, was able to load both the closure and the dispenser as easily and efficiently as possible.

The present invention has led to the discovery that, if the invented known zaanaknpakha is intended to be met with a metering valve, it is easy for the valve to open easily under reduced pressure and. with pressure befcfezi to back down just as easily, then for alto I have to grow o the whole valve from a weaker, mgalmasabh material, hanoin is enough to weaken the valve wings only, and so the task set for colul is accomplished.

Your badge has served a purpose. The present invention provides a stepless delivery of substances, such as high viscosity, from a storage vessel for dispensing stopper beer material, which fits into a socket and has a lid opening that is permeable to the container when temporarily pressurized. placed on the neck, togahnas selcpt body w implanted, inside the mucosa there are uomomebot projecting to the azsleptesf, the valve roofs on the side of the container facing the neck. the cushioning foot is formed along its perimeter, and the extension to the inside of the neck is attached to the sole, and the opposite end of the extension is provided by the cows, under the pressure of the storage space, the azeepad is displaced from its own plane by a temporary deflection - it is formed in such a way that the surface of the slits between the slits is deepened by the weakening trenches which are traced through the membrane along the slits are located between the endpoints farthest from the center of the star, the azefept

A further feature of the invention is that the weakening curse is supplemented by a medial direction.

The effective operation of the dispensing closure is advantageous for the shampoo, with the inner peripheral surface of the neck and the matching outer peripheral surface of the protrusion week tightly fitting to each other.
