Embodiment Construction

[0017] Referring to the accompanying drawings, the dispenser according to the present invention consists of the following parts:

[0018] a pump 2, for example a screw pump, fed by an interchangeable liquid-containing flask 1 via line 12;

[0019] an intermediate tank 3, fed by said pump 2 via pipe 21, said tank being equipped with one or more level probes 31-33 and possibly a temperature probe 34;

[0020] a high-precision pump 4, preferably of the type with one or more pistons, fed liquid from said intermediate tank 3 via pipe 35 and valve 7;

[0021] A three-way solenoid valve 5 is arranged downstream of the high-precision pump 4, where the valve receives input liquid and has two output passages, one output passage is connected to the storage tank 3 via a pipeline 51, and the other output passage connected via a pipe 52 to a terminal receiver 6 for collecting the liquid to be delivered; and

[0022] A microprocessor unit for controlling and managing said pump 2 and said h...

Abstract

The present invention refers to a flask for liquids, for use in precision dispensers for liquids, which flask consists of a main body provided with a threaded neck equipped with means for the press-block coupling of an attachment of a dispenser, in which the bottom of the flask consists of a pair of surfaces, which are inclined and which converge centrally into a cup forming the lowest point of storage of the liquid in the flask.

Description

[0001] This application is a divisional application of the patent application whose application number is 00805062.7, the application date is March 14, 2000, and the invention title is "Precise Liquid Dispenser and Method for Measuring Liquid Dose". technical field [0002] The present invention relates to a precision doser for controlling the delivery of a liquid product, especially for the preparation of methadone or other pharmaceuticals, and to a flask for containing a liquid, especially for use in a precision liquid doser . Background technique [0003] In the prior art, known methadone liquid dispensers draw a predetermined amount of liquid from a feed tank via a screw pump. The liquid dose is then poured into a glass that will be taken by the patient. These known dosing devices are generally recognized and operated by computer for the management of the different patient scenarios. [0004] However, these known dispensers suffer from a number of deficiencies, especia...
