Liquid dispensing dosing device for a liquid receptacle
View Patent ↗The invention comprises a cylindrical reservoir ( 1 ) with a mouth ( 14 ), side through hole ( 3 ), shaft ( 28 ) and perimeter flange ( 8 ) whose top is associated with a concentric cover ( 2 ) anchored to the container ( 6 ) equipped with an upper mouth ( 13 ), vertical or diagonal grooves ( 16 ) and a lower mouth ( 11 ); the cover ( 2 ) enables the rotary or longitudinal sliding of the reservoir ( 1 ), which is activated by the pressure exerted by the cap (T) on said reservoir ( 1 ) which descends when the container is closed and takes the side through hole ( 3 ) out from inside the cover ( 2 ), descent that enables the reservoir ( 1 ) to be filled; when removing said cap (T), the reservoir ( 1 ) rises driven by the compression means ( 10 ), ( 17 ), ( 24 ) or ( 25 ) leaving the through hole ( 3 ) thereof enclosed inside the cover ( 2 ); the dose (Ds) is selected by tipping over the container ( 6 ) and when the liquid returns to the vertical position and is levelled, it is calibrated and when the cap is unscrewed, it is served and used, and so on.
1 . A liquid dispensing dosing device for a liquid receptacle with a dispensing neck that can be closed with a cap, the dosing device comprising:
first coupling means ( 12 ) for coupling the dosing device to a neck ( 5 ) of a liquid receptacle;
a liquid reservoir ( 1 ) comprising a liquid inlet hole ( 3 ), the liquid inlet hole ( 3 ) being arranged to be inserted into the liquid receptacle when the dosing device is coupled by means of the first coupling means ( 12 );
a cover ( 2 ) for the liquid inlet hole ( 3 ), the cover ( 2 ) and the reservoir ( 1 ) being slidably connected;
in which the reservoir ( 1 ) comprises a top, a bottom and a side wall that joins the bottom to the top, wherein the top is open to the outside, the side wall comprises the liquid inlet hole ( 3 ) and the bottom comprises a wall that extends to the side wall, preventing liquid from entering below the liquid inlet hole ( 3 ),
the dosing device having:
a first configuration wherein the cover ( 2 ) covers the liquid inlet hole ( 3 ) of the reservoir ( 1 ), preventing liquid from passing through the liquid inlet hole ( 3 ), the liquid reservoir ( 1 ) comprises a protrusion ( 8 ) configured to come in contact in a leak-tight manner with the cover ( 2 ) in the first configuration,
a second configuration wherein the cover ( 2 ) does not cover the liquid inlet hole ( 3 ), allowing liquid to enter the liquid reservoir ( 1 ) through the liquid inlet hole ( 3 );
second coupling means ( 29 , 88 ) for coupling to the cap (T) of the liquid receptacle configured to be pressed by the cap (T) in a closure of the dispensing neck ( 5 ) so as to cause sliding between the liquid reservoir ( 1 ) and cover ( 2 ), going from the first configuration to the second configuration;
return means ( 10 , 17 , 22 , 24 , 25 ) for returning from the second configuration to the first configuration and configured to cause sliding between reservoir ( 1 ) and cover ( 2 ), going from the second configuration to the first configuration by releasing the pressure exerted by the cap (T) on the second coupling means for coupling to a further cap ( 29 ) at the opening of the dispensing neck ( 5 );
characterized in that the return means ( 10 , 17 , 22 , 24 , 25 ) are adopted on the cover ( 2 ) as part of the cover ( 2 ).
2 . The dosing device according to claim 1 , characterized in that the cover ( 2 ) adopts as return means at least two spokes ( 25 ) which converge in a small cylinder ( 18 ), the cover ( 2 ) and the spokes ( 25 ) being made of an elastomeric polymer whose geometry, when altered by pressure and said pressure then ceasing, returns to the previous shape and position thereof.
3 . The dosing device according to claim 2 , characterized in that the small cylinder ( 18 ) is provided with a through hole ( 26 ) that receives anchoring tabs ( 29 ) of a shaft ( 28 ) that join it to the reservoir ( 1 ), the reservoir ( 1 ) being fastened to an inner shaft ( 28 ) of the reservoir and wherein the shaft ( 28 ) is joined to the cover ( 2 ) by the return means in the form of said spokes ( 25 ).
4 . The dosing device according to any one of the preceding claims , wherein the cover ( 2 ) comprises a face oriented towards the hole ( 3 ) of the reservoir and wherein said face has a protrusion configured to come in contact in a leak-tight manner with the reservoir ( 1 ) in the first configuration.
5 . The dosing device according to claim 1 , wherein the first coupling means ( 12 ) for coupling to a neck ( 5 ) comprise a bushing wherein the cover ( 2 ) is part of the bushing with a perimeter protrusion ( 12 ).
6 . The dosing device according to claim 5 , wherein the cover ( 2 ) comprises a channel ( 16 ) or a protrusion and the reservoir ( 1 ) comprises, respectively, a protrusion ( 15 ) complementary to the channel ( 16 ) of the cover or a channel complementary to the protrusion of the cover ( 2 ).
