Abstract

An apparatus for injecting a dose of medication into a bottle includes a tank, an outlet or mouth, a doser, and a conduit connecting the tank, the outlet mouth and the doser to each other. The conduit includes a portion disposed between the doser and the outlet mouth. The apparatus additionally includes a valve and a cursor movable internally of the portion of the conduit between an occluding position and an enabling position. A first magnet is borne by the cursor, while a second magnet arranged externally of the conduit is movable beside the conduit and interacts magnetically with the first magnet so that the second magnet is able to draw the cursor between the occluding position and the enabling position.

First claim

The invention claimed is:

1. An apparatus for injecting a dosed quantity of medicinal liquid internally of a bottle, comprising:
a tank containing a medicinal liquid;
an outlet mouth;
a doser for receiving the medicinal liquid from the tank and for expelling a dosed quantity of medicinal liquid through the outlet mouth and internally of a bottle;
a conduit connecting the tank, the doser and the outlet mouth to one another, which conduit comprises a first portion of the conduit which is interposed between the doser and the outlet mouth;
a valve interposed along the conduit between the tank and the doser, so as to prevent or enable passage of medicinal liquid between the tank and the doser;
a first cursor that is mobile internally of the first portion of the conduit between an occluding position, in which it occludes passage of medicinal liquid towards the outlet mouth, and an enabled position, in which it enables passage of medicinal liquid towards the outlet mouth, further comprising: a first magnet which is borne by the first cursor;
a second magnet which is arranged externally of the conduit, which is mobile by a side of the conduit and which is able to interact magnetically with the first magnet when the second magnet is at the first portion of the conduit, such that when the second magnet moves by a side of the first portion of the conduit, the second magnet is able to draw the first cursor between the occluding position and the enabled position, wherein:
the first portion of the conduit develops between a first end and a second end;
the conduit comprises a second portion of the conduit, which borders with the first end of the first portion of the conduit, and a third portion of the conduit, which borders with the second end of the first portion of the conduit;
a first abutment is arranged at the first end of the first portion of the conduit, which halts the first cursor when the first cursor reaches the occluding position; and
a second abutment is arranged at the second end of the first portion of the conduit, which halts the first cursor when the first cursor reaches the enabled position; and
wherein:
the second magnet is positionable by a side of the second portion of the conduit or by a side of the third portion of the conduit in a rest position in which the second magnet does not interact magnetically with the first magnet; and
the doser is configured and arranged with respect to the first portion of the conduit so that when the doser aspirates the medicinal liquid from the tank a depression is created at the first portion of the conduit which determines an abutment of the first cursor against the first abutment, and that when the doser expels a dosed quantity of medicinal liquid an overpressure is created at the first portion of the conduit which determines an abutment of the first cursor against the second abutment.

2. The apparatus of claim 1 , wherein the first abutment is defined by a first change in transversal section of the first portion of the conduit.

3. An apparatus for injecting a dosed quantity of medicinal liquid internally of a bottle, comprising:
a tank containing a medicinal liquid;
a doser for receiving the medicinal liquid from the tank and for expelling a dosed quantity of medicinal liquid through the outlet mouth and internally of a bottle;
a conduit connecting the tank, the doser and the outlet mouth to one another, which conduit comprises a first portion of the conduit which is interposed between the doser and the outlet mouth;
a valve interposed along the conduit between the tank and the doser, so as to prevent or enable passage of medicinal liquid between the tank and the doser; and
a first cursor that is mobile internally of the first portion of the conduit between an occluding position, in which it occludes passage of medicinal liquid towards the outlet mouth, and an enabled position, in which it enables passage of medicinal liquid towards the outlet mouth, further comprising:
a first magnet which is borne by the first cursor; and
a second magnet which is arranged externally of the conduit, which is mobile by a side of the conduit and which is able to interact magnetically with the first magnet when the second magnet is at the first portion of the conduit, such that when the second magnet moves by a side of the first portion of the conduit, the second magnet is able to draw the first cursor between the occluding position and the enabled position, wherein:
the first portion of the conduit develops between a first end and a second end; and
the conduit comprises a second portion of the conduit, which borders with the first end of the first portion of the conduit, and a third portion of the conduit, which borders with the second end of the first portion of the conduit;
further comprising a first abutment arranged at the first end of the first portion of the conduit, which halts the first cursor when the first cursor reaches the occluding position,
wherein:
the first portion of the conduit has an internal diameter that is greater with respect to the internal diameter of the second portion of the conduit;
the internal wall of the first portion of the conduit comprises a first part and a second part which conjoins the first part to the internal wall of the second portion of the conduit;
the second part of the first portion of the conduit forms, with the first part of the first portion of the conduit, an angle of greater than ninety degrees so that the first abutment is identified by the change of internal diameter which is defined between the first part of the first portion of the conduit and the internal wall of the second portion of the conduit.

4. The apparatus of claim 1 , wherein the second abutment is defined by a second change in transversal section of the first portion of the conduit.

5. The apparatus of claim 1 , wherein:
the first portion of the conduit has an internal diameter that is greater with respect to an internal diameter of the third portion of the conduit;
the internal wall of the first portion of the conduit comprises a first part and a third part which conjoins the first part with the internal wall of the third portion of the conduit; and
the third part of the first portion of the conduit forms, with the first part of the first portion of the conduit, an angle of greater than ninety degrees so that the second abutment is identified by the change of internal diameter that is defined between the first part of the first portion of the conduit and the internal wall of the third part of the conduit.

6. An apparatus for injecting a dosed quantity of medicinal liquid internally of a bottle, comprising:
a tank containing a medicinal liquid;
an outlet mouth;
a doser for receiving the medicinal liquid from the tank and for expelling a dosed quantity of medicinal liquid through the outlet mouth and internally of a bottle;
a conduit connecting the tank, the doser and the outlet mouth to one another, which conduit comprises a first portion of the conduit which is interposed between the doser and the outlet mouth;
a valve interposed along the conduit between the tank and the doser, so as to prevent or enable passage of medicinal liquid between the tank and the doser; and
a first cursor that is mobile internally of the first portion of the conduit between an occluding position, in which it occludes passage of medicinal liquid towards the outlet mouth, and an enabled position, in which it enables passage of medicinal liquid towards the outlet mouth, further comprising:
a first magnet which is borne by the first cursor; and
a second magnet which is arranged externally of the conduit, which is mobile by a side of the conduit and which is able to interact magnetically with the first magnet when the second magnet is at the f
