bottle by means of a conventional threaded system in such a way that it is possible to keep the cap attached to the container in a closed or open position.

During the operation of unscrewing the cap to access the interior contents of the container, it is the section of the lower ring where it is in a hinged section that rises, since the retention means that retain the lower ring in the lower part of the area are not available in that area threaded section of the neck or neck of the container.

In addition, when the lower ring has risen during the unscrewing process, when stretching and wanting to return to its initial position it will be fixed in the threaded section, which allows the lower ring not to rotate, the upper cap not being an obstacle or difficulty during the pouring action of the liquid or the drinking action directly from the container.

In a first embodiment of the invention, the retaining means comprise a plurality of tabs separated from each other by interstices, protruding from the inner flange of the lower ring.

In an alternative embodiment, the retaining means comprise an elongated extension (flexible or rigid), protruding from the inner flange of the lower ring, which has a contour parallel to a part of the lower ring.

Preferably, the retention means are present in approximately half of the total circumference of the lower ring, in which the section of the lower ring where the hinged portion is located is devoid of such retention means.

Advantageously, the closure cap is made of a single piece of injectable plastic material, which simplifies the manufacturing process and reduces costs.

According to another feature of the invention, the closure cap may include an inviolability seal. In a preferred embodiment, said inviolability seal may consist of a plurality of junction points linking the lower ring and the upper cap.

Other features and advantages of the closure cap for packaging object of the present

invention will be apparent from the description of a preferred embodiment, but

DESCRIPTION OF A PREFERRED EMBODIMENT

In view of the aforementioned figures and, according to the numbering adopted, an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated and described in detail below.

As shown in the attached figures, the closure cap for containers of the invention, is in particular intended to close packages (see Figure 5) having an opening in a neck (100) provided with a threaded outer portion (101 ), comprising a lower ring (1) intended to be coupled to the neck (100) of the container and an upper cap (2) provided on its inner wall with a section that has a filleting provided to engage tightly with the threaded outer portion of The opening of the container.

The lower ring (1) and the upper cap (2) are articulated together by means of a portion

hinged (3), the lower ring (1) presenting retaining means (which will be detailed

later) present in a diametral section of the inner flange (11) of the lower ring (1),

being provided to be in contact with the lower part of the threaded outer portion of the neck. As can be seen, the diametral section corresponds to approximately half of the total circumference of the lower ring, such that the section of the lower ring where the hinged portion (3) is located is devoid of such retaining means, which allows flexion of this section in the upward direction (see figure 6) when the user carries out the unscrewing action of the upper plug (2), as can be seen in figure 3.

In the embodiment shown in Figure 1, the aforementioned retaining means comprise a plurality of tabs (4) separated from each other by interstices, protruding from the inner flange of the lower ring.

In the embodiment shown in Figure 2, where equal parts have the same numerical references, the retention means comprise a single elongated flexible extension (4 '), protruding from the inner flange of the lower ring, which has a contour parallel to a part of the lower ring (1).

In Fig. 4 another alternative embodiment can be seen that differs from the previous ones, essentially in the fact that the retention means comprise a plurality of flanges (4 ") arranged in approximately 50% of the total length of the lower ring (1 ), each of the tabs (4 ") being raised and inclined with respect to a perpendicular axis.

In case the separation of the closure cap assembly described herein with respect to the body of the bottle is suitable, for example, in the waste treatment plant, the lower ring (1) includes a pair of areas of weakened breakage (12) that are formed by cross sections of smaller thickness that facilitate their breakage. Mention that each of the weakened break zones (12) on both sides of the hinged portion (3).

Finally, the closure cap may include an inviolability seal consisting of a plurality of junction points (5) that link the lower ring and the upper cap, as can be seen in Figures 5 and 6.
