DESCRIPTION OF A PREFERRED EMBODIMENT

[0024] In light of the aforementioned figures, and in accordance with the adopted numbering, one may observe therein a preferred exemplary embodiment of the invention, which comprises the parts and elements indicated and described in detail below.

[0025] As shown in the attached figures, the closing cap for containers is particularly intended for containers that have an opening in a neck (100) provided with an outer threaded portion (101), comprising a lower ring (1) intended for being coupled to the neck (100) of the container and an upper cap (2) having an inner threaded region (20) (see FIG. 6) configured for being coupled to the outer threaded portion (101) of the container neck.

[0026] The upper cap (2) and the lower ring (1) are articulated to each other by means of a hinged portion (3), which makes it easier for the user to manipulate the closing cap and prevents both portions from being separated, as the entire set is made of a single piece of injectable plastic material.

[0027] An outer surface of the lateral face defined by the body of the upper cap has a non-smooth surface (21), for example, a knurled surface formed by ribs extending from the upper portion to the lower portion of the body of the upper cap.

[0028] The lower ring (1) of the closing cap is made up of an annular-shaped body and has a first section (10) with a diameter larger than a second one (11) that corresponds to the remaining section of the annular-shaped body, the hinged portion (3) being located in the section (10) with the larger diameter. As can be clearly seen in FIGS. 1 and 2, both sections (10) and (11) are attached by two curved sections (12) arranged diametrically opposed to each other.

[0029] It should be noted that the section with the smaller diameter has a diameter such that it is located in a region (104) defined by two circumferential rims (102, 103) provided in the lower portion of the neck of the container, so that during the operation in which the upper cap rises to separate the upper cap (2) from the upper opening of the container, the ring remains in this region at all times.

[0030] Thus, these two sections with different diameters enable a controlled stretching and subsequent return to the initial position thereof, which enables, once the upper cap has been unscrewed, the lower ring (1) to be comfortably stretched, holding from the upper cap (2), to house a portion of the section with the larger diameter (10) and the hinged portion (3) below the lowermost circumferential rim (103) of the container, as shown in FIG. 5. In this way, the upper cap (2) is perfectly locked, as the inner face of the hinged portion (3) abuts the lower portion of the circumferential rim (103).

[0031] Returning again to the hinged portion (3), as can be seen in FIGS. 1 and 2, it is formed by an extension of a substantially rectangular shape that at the upper end thereof is attached to the upper cap (2) and at the lower end thereof is attached to the lower ring (1), such extension being devoid of fold lines, unlike other closing cap systems known in the current state of the art.

[0032] Additionally, the closing cap is provided with a tamperproof seal located between the upper cap (2) and the lower ring (1). As can be seen, this tamperproof seal is made up of a plurality of breaking points (4) located on a rim (5) of the lower ring (1) that protrudes outwards and attached to a lower edge of the upper cap (2).

[0033] As can be seen in the attached figures, the rim (5) that protrudes outwards is located only in the smaller diameter section (11).

[0034] FIGS. 7 and 8 show a second preferred embodiment of the closing cap, wherein the same portions or parts are indicated with the same numerical references as in the example described above. In this second embodiment, the upper cap (2) advantageously includes an abutment means configured for being in contact with the circumferential rim (103) of the neck (100) in the open position of the upper cap with respect to the lower ring, so that it is ensured that the upper cap (2), when it is in the open position, does not rotate in an undesired way by effect of the hinged portion (3) to return to the rest position thereof, that is, when the upper cap (2) is on top of the lower ring (1).

[0035] As can be seen, the abutment means consists of a flange (22) that extends outwardly from the inside of the body that makes up the upper cap (2) and parallel to the hinged portion (3). As can be seen in FIG. 7, said flange (22) takes a position practically or completely parallel to a longitudinal axis of the neck itself (100) and the hinged portion (3) is housed below the circumferential rim (103).

[0036] Lastly, it should be mentioned that the smaller diameter section (11) of the lower ring includes a circumferential projection (13) that protrudes outwards.

[0037] The details, shapes, dimensions and other accessory elements, used to manufacture the closing cap of the invention, may be suitably substituted for others which do not depart from the scope defined by the claims which are included below.
