DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a dosing apparatus for dispensing predetermined quantities preferably of beverages from a bottle or a similar object, said dosing apparatus being adapted to be fastened at the orifice of the bottle and comprising an inlet opening, an outlet opening as well as a magnetically operated first valve device, which by activation enables the beverage to flow from the dosing apparatus through the outlet opening, and said apparatus having an air valve for equalizing pressure in the inner of the bottle during outflow.
BACKGROUND ART
Dosing apparatuses are known having a valve device which, when activated by an electromagnet, preferably disposed in a ring through which the dosing apparatus is placed at the dispensing, is opened for a predetermined period of time, so that the beverage is allowed to flow out of the bottle with the dosing apparatus through said dosing apparatus, until the valve device is closed again. These known dosing apparatuses which thus deliver a predetermined quantity of beverages determined by the opening time of the valve device claim an exact adjustment of time dependent on the viscosity of the beverage in question.
DISCLOSURE OF INVENTION
The dosing apparatus according to the invention is characterised in that the apparatus comprises a total cavity corresponding to the desired dosage quantity, and in that the apparatus comprises a second valve device adapted to turn off the outflow of beverage from the bottle to the dosing apparatus, while the first valve device is open to outflow, in that the apparatus comprises means ensuring a forced closing of the second valve device before the first valve device is opened, and an automatic opening of the second valve device, when the first valve device has been closed.
A dosing apparatus is hereby provided which permits dispensing of predetermined quantities of beverages independent of a specific time interval, as there will never flow more liquid out of the dosing apparatus than is present in its inner cavity. This is especially due to the fact that because of the second valve device the dosing apparatus permits no liquid to flow out of the bottle as long as the dispensing takes place, i.e. as long as the first valve device is open. Of course, the quantity dispensed corresponds to the size of the cavity, which may be adjusted by means of adjustment parts capable of being screwed in. Due to the fact that the second valve device is also in closed position, while the first valve device is open, the dosing apparatus may if desired be connected with a locking arrangement securing that a bottle placed through a fixed, annular actuation device cannot be removed before the locking arrangement is released after a predetermined time interval. The user is hereby prevented from interrupting the dispensing before it is ended by raising the bottle in advance. By leaving the first valve device open for a comparatively long time it is ensured that the customer will always get the quantity of beverage corresponding to the volume of the dosing apparatus irrespective of the beverage being of low or of high viscosity.
In an especially advantageous embodiment the first and the second valve device may each comprise a loose, separate valve body, adapted to cooperate with the outlet opening and the inlet opening, respectively, so that the opening in question is closed tightly, when the valve device in question is in closed position.
Furthermore according to the invention the magnetical activation of the first valve device may be ensured by means of a separate, magnetically activable displacement body constructed to be moved forwards and backwards in a predetermined path within the dosing apparatus in such a way that by activation it is displaced in one direction of the path and hereby pulls the first, loose valve body away from its closed position, substantially immediately after the second valve body has been brought into closed position. It is hereby made possible to construct a displacement body which is comparatively big and t
