DESCRIPTION

OBJECT OF THE INVENTION

The present invention relates to a stopper, used to cover the outlet of the bottles or containers. Specifically, with a cap that fits all bottle or container mouth sizes.

BACKGROUND OF THE INVENTION

Various types of caps for bottles or containers are known, which comprise a pouring body that is inserted into the mouth of said bottle or container. The pouring body is closed with a lid and can comprise means that prevent refilling the bottle or container, for example, a sphere or ball that sits in a liquid inlet / outlet hole, which, once said body Pouring is positioned at the mouth of the bottle or container, it only allows the transfer of liquid to the outside of the bottle or container, and not, to the inside of it.

These pouring bodies of the known caps are shaped with dimensions that fit the size of the mouth of the bottles or containers, thus, a plastic injection mold is needed for each size of pouring body to be formed, corresponding to each mouth size of bottle or container to cover. Which has the disadvantage of the high cost of obtaining each injection mold.

For this reason, it is necessary to design a bottle or container cap that, in a simple and economical way, allows to overcome the previous disadvantage.

On the part of the applicant, it is unknown the existence of a cap for bottles or containers that shows similar characteristics to those presented by the invention that is recommended here.

The present invention is established and characterized in the independent claims, while the dependent claims describe other features thereof.

The object of the invention is a cap that fits in all sizes of mouth of bottles or containers. The technical problem to be solved is to avoid the plurality of plastic injection molds required for the conformation of different sizes of caps corresponding to the sizes of existing bottle or container mouths.

An advantage of the invention, in relation to claim 1, is that it manages to solve the technical problem raised, then, the particular composition of the elements that make up the cap, including a cork cylinder between the pouring body and the mouth of the bottle or container in which it is inserted, allows, for all sizes of bottle or container mouth, to use a single plastic injection mold for the conformation of the pouring body, which is then adjusted to the interior dimensions of the mouth of the bottle or container, varying the wall thickness of the cork cylinder to be arranged between them.

Another advantage in relation to claims 2 to 4, is that the pouring body is provided with means that, once inserted, prevent its extraction from inside the cork cylinder, as well as, the rotation between said elements.

Another advantage in relation to claim 5 is that the means preventing the rotation between the pouring body and the cork cylinder are shaped so as to facilitate the initial coupling of both elements.

Another advantage in relation to claim 6 is that the pouring body is provided with means that prevent refilling of the bottle or container.

Another advantage in relation to claim 7 is that the cover is provided with means for fixing a decorative cap thereon.

The present specification is complemented, with an illustrative figure of the preferred and never limiting example of the invention.

Figure 1 represents a front sectional view of the cap of the present invention coupled to the mouth of a bottle or container.

DETAILED EXHIBITION OF THE INVENTION

In view of the foregoing, the present invention relates to a stopper for employees to cover bottles or containers, as well as pouring the liquid contained therein.

As shown in Figure 1, the cap comprises:

- a pouring body (1) with a coupling end (1.1) that can be inserted into a mouth (2) of the bottle or container, and

- a cover (3) coupled to an outlet end (1.2) of the pouring body (1), closing the access to said pouring (1).

Preferably, between the coupling end (1.1) and the outlet end (1.2), the pouring body (1) comprises a lateral projection (1.3), which, once the pouring body (1) is inserted in the mouth (2) ) of the bottle or container, sits on the edge of said mouth (2).

Between the coupling end (1.1) of the pouring body (1) and the mouth (2) of the bottle or container there is a hollow cork cylinder (4), which adjusts the outer dimensions of the pouring body (1) to the interior dimensions of the mouth (2) of the bottle or container. The outer wall of the cork cylinder (4) could have a slight inclination, either in the direction inside or outside the bottle or container, as required by the type of product contained in said bottle or container.

Thus, it is only enough to vary the thickness of the wall of the hollow cork cylinder (4) so that a single size of pouring body (1) can be adjusted to the different sizes of mouth (2) of bottle or container where required insert. A unique plastic injection mold is necessary for the conformation of the pouring bodies (1), avoiding the high

costs that involve having a plastic injection mold for each size of pouring body (1) to be shaped.

On the other hand, it is preferred that the coupling end (1.1) of the pouring body (1) comprises at least one transverse retaining ring (1.11) in its outer wall, which, after inserting the pouring body (1) into the cylinder Cork (4), prevent its extraction. For example, in the embodiment shown in the figures, the transverse retaining ring (1.11) is conically shaped, with increasing generatrix towards the outlet end (1.2) of the pouring body (1). However, it could be configured in any other geometry, preferably that, at first, facilitates the insertion of the pouring body (1) into the cork cylinder (4), and then, prevents both elements from separating.

Likewise, it is preferred that the coupling end (1.1) of the pouring body (1) also comprises at least one longitudinal projection (1.12) in its outer wall, which prevents rotation of the pouring body (1) with respect to the cylinder of cork (4). Preferably, the longitudinal projection (1.12) comprises an insertion end (1,121) in the cradle-shaped cork cylinder (4), whereby said insertion of the pouring body (1) into the cork cylinder (4) is provided. ).

In a preferred embodiment of the invention, the coupling end (1.1) of the pouring body (1) is designed with a plurality of longitudinal projections (1.12) arranged equidistant from each other and extended from the lateral projection (1.3) of the pouring body (1) ). Following the longitudinal projections (1.12), in the direction of the interior of the bottle or container, a plurality of transverse retaining rings (1.11) are arranged.

On the other hand, it is preferred that the pouring body (1) houses inside a sphere (5), which acts as a means to prevent refilling of the bottle or container.

Likewise, it is preferred that the cover (3) comprises longitudinal stripes (3.1) on its lateral face, which allows a cap (6) to be snapped onto said cover (3). The cap (6) of the embodiment shown in the figure is cylindrical in shape, however, it could be shaped with any geometric configuration, with a view to giving a better or particular aesthetic appearance to the bottle or container cap.

Also, for example, for aesthetic purposes, the cap (6) could be made of wood.

Similarly, on the lateral projection (1.3) of the pouring body (1), and covering the mouth (2) of the bottle or container, in a tight manner, a guarantee closure (not shown in the figures) of the known, which allows to leave indications in case the pouring body (1) has been removed from the mouth (2) of the bottle or container; with a view that 5 possible manipulation or unauthorized change of the original contents of the bottle or container can be detected.
