Last but not least, there is the fact that most of the current caps do not meet the aesthetic requirements necessary for incorporation into containers for direct use by customers in the room in the field of restoration.

DESCRIPTION OF THE INVENTION

The present invention relates to a dosing cap for liquids, which allows greater precision in use, as well as a regulation of flow intensity with a watt system so that the product does not lose properties. The cap of the invention is constituted as an integrated warranty seal, in addition to being economical and extremely versatile, since it admits very diverse uses and applications, both in the food sector, as in the beverage, industrial, pharmaceutical or medical sectors, To name a few applications. In addition, the entry of air or contaminating fumes from outside to the inside of the container is avoided at all times, both during the dispensation and in the closing position, which prolongs the organoleptic properties of the contained product, with the consequent appreciation by the users .

The cap proposed by the invention comprises a dosing body, which can be inserted into a neck of a container container and which, through the intervention of a dosing element, which can consist of a valve or a ball, can accommodate at least one dose of liquid to dispense The dosing body is the piece in charge of generating the doses to serve, which is possible thanks to its geometry.

Also, the cap comprises a base piece which in turn comprises an inner cylindrical wall and an outer cylindrical wall, preferably concentric, between which the neck of the container can be coupled, the base piece being attached to the metering body. The base piece is responsible for joining the cap with the bottle, strengthening its proper functioning, for this it includes projections and clips located on the inner face of its outer cylindrical wall that are what allow to ensure a good union to the bottle. According to a preferred embodiment, the base part incorporates a filter attached to the base. Dosing body and base piece are joined by clipping located in the upper area of the dosing body and the lower part of the inner cylindrical wall of the base piece.

Well, according to the invention, the cap comprises a dispensing piece which in turn comprises a cylindrical section, open at the bottom, which is extended in a spout, where the cylindrical section is housed internally in the wall

inner cylindrical of the base piece. The dispensing piece is responsible for pouring the oil.

Likewise, the cap comprises an activation wheel that is connected with the possibility of rotation with respect to the base piece, where said activation wheel comprises an outer cylindrical wall, on which a user acts, which is above the outer cylindrical wall of the base piece, and which extends inferiorly in an inner cylindrical wall that is positioned tightly between the inner face of the inner cylindrical wall of the base piece and the outer face of the cylindrical section of the dispensing part.

According to the invention, the outer face of the cylindrical section of the dispensing part comprises at least one projection or pivot, preferably two located in diametral opposition, in any case located inferiorly that is simultaneously housed in a diagonal gtia located in the cylindrical wall inside the activation wheel and in a vertical gtia, that is to say parallel to a generatrix of the cylindrical walls, which has the inner cylindrical wall of the base piece.

Thus, turning the activation wheel with respect to the base part produces a vertical displacement of the dispensing part, by virtue of the passage of said at least one projection, along the diagonal guide and the vertical guide simultaneously.

The vertical guide of the base piece is the conditioner so that the mouth can only exert a vertical movement. The activation wheel is the piece that executes the mechanism. The activation wheel and the base part are joined by a clipping that prevents vertical translation but allows rotation. It is designed so that the liquid cannot leave between these pieces.

The position of the pouring spout is a direct visual indicator of the closing or opening position of the plug, as well as the degree of opening.

The cap of the invention allows a dosage with great precision in use, where the flow intensity can be regulated, so it is very practical, in addition to the shrinkage of the pouring spout. The ford system causes the product to not lose properties.

The cap of the invention is economical and can be manufactured with materials such as plastic, metal, wood, cork, etc.

It is contemplated that the activation wheel comprises a horizontal surface that links the outer and inner cylindrical walls, wherein said horizontal surface comprises a dispensing orifice intended to face a correspondingly located hole in a horizontal surface that inferiorly closes the inner cylindrical wall of the base piece, so that the relative position of confrontation between both holes allows to regulate the flow rate of liquid dispensing.

In the case of not facing the holes, which obviously coincides with the lower position of the dispensing piece, the plug is in the closed position and the liquid dispensing is prevented.

The user turns the activation wheel, preferably up to a maximum of 180 °, and the system is operated. In the lower part, the hole can correspond to a quarter of a circle, thus being the hole that regulates the outflow. In this way, the cap can be designed so that in the intermediate position it is served at half flow and in the total opening position it can be served at 100% of the possible flow. To close the cap and not to leave liquid, the activation wheel is turned in the opposite direction to the opening until its end stop.

The possibility is contemplated that the cap comprises a cover that is attached without the possibility of turning to the base piece, where said cover comprises at least one recess that allows access from the outside to the outer cylindrical wall of the activation wheel, also comprising a hole that allows the passage of the pouring spout of the dispensing piece.

The lid is the element that hides the rest of the elements of the plug. The lid is pressurized by means of clips located on its two legs of the base piece, which prevents it from being fraudulently manipulated to fill the container, as well as its accidental loss, since it does not have to be manipulated to use the plug. The pouring spout or mouth of the dispensing piece, which is retractable, emerges from its orifice. When the activation wheel is turned, the dispensing piece moves vertically out of the hole in the top of the lid.

It is contemplated that the activation wheel comprises a protection zone that is facing superiorly, plugging, to the spout when the dispensing piece is in its lower position, simultaneously plugging the hole of the lid, of

so that the diagonal gda of the activation wheel is extended inferiorly in a horizontal section, which allows the removal of the protection zone by turning without vertical displacement of the dispensing part.

Finally, it is contemplated that the pouring spout of the dispensing piece comprises a narrow, external channel, which flows into an orifice that allows the excess liquid to be redirected during dispensing into the hollow interior of the dispensing piece. Thus, the external channel is constituted as a small slit along the entire diameter of the pouring spout that ends in a hole so that the excess oil flows through this area until it is reintroduced into the bottle by the force of gravity itself, thus having overflow and anti-drip means.

Considering that the plug comprises eight elements, its assembly sequence is as follows. First, a filter is attached to the base piece that holds the entire system to the bottle. The dispensing piece is inserted into the activation wheel, leaving the projections inside the gdas. This set is inserted on the base piece. The pressure activation wheel is introduced, until it stops with the base piece. The cover is placed, joined by snap clips, for which it must be aligned with the protection zone of the activation wheel. The ball of the dosing element is introduced on the lower lid to then attach this assembly to the dosing body. Once these pieces are assembled, the assembly is completed by joining the upper part of the dosing body with the lower part of the base piece.
