PREFERRED EMBODIMENT OF THE INVENTION

[0024] A detailed explanation of a preferred embodiment of the object of the present invention is provided below, with the help of the aforementioned figures.

[0025] The anti-splash hinged closing cap for pouring holes for containers holding liquids described is intended to be attached to the neck of a container. The cap, shown in FIG. 1, consists of a lower ring (1), intended to be retained in the neck of the container, and an upper lid (2), intended to cover the pouring holes of the container to seal it. A hinging element connects the lid (2) with the ring (1) in a hinged manner.

[0026] The ring (1) comprises gripping means for its retention to the neck, when opening and closing the cap. The lid (2) comprises an upper base (3) attached to a lower perimeter wall (4). From an edge of the perimeter wall (4) projects a transversal visor (5) to allow the opening and closing of the lid (2) by manual operation.

[0027] The upper base (3) also includes a cylindrical skirt (6) emerging from its inner face and sized for its insertion inside the neck of the receptacle to improve the tightness of the closure.

[0028] FIGS. 1 and 2 show the rear part of the cap, where the hinging element between the lid (2) and ring (1) is arranged. As can be seen, in a sector of the perimeter wall (4) diametrically opposed to that from which the visor projects (5), there are two pairs of vertical notches (7) arranged parallel to an axial axis of the cap, which define the formation of two flexible joint strips (8) that link the lid (2) with the ring (1). These binding strips (8) have an upper end, attached to the lid (2), and a lower end, attached to the ring (1).

[0029] In this preferred embodiment, as shown in FIG. 3, the lid (2) comprises two recesses (9) located on the outer perimeter edge of its upper base (3) and a pair of perimeter incisions (10) in these recesses (9). The perimeter incisions (10) define a flexible junction with the respective upper ends of each of the binding strips (8), which are also configured to provide a continuous perimeter edge of the upper base (4). This feature allows the cap to be centered in encapsulation heads, thus facilitating packaging manufacture.

[0030] The upper base (3) has a tab (11), located between the recesses (9), which allows the cap to open more than 180. The ring (1) comprises a protrusion (12) arranged between the binding strips (8), intended to cooperate with the tab (11) when the lid (2) is in its open position, as shown in FIGS. 5 and 6.

[0031] This tab (11) and protrusion (12) configuration allows a lid opening (2) greater than 180. Said tab (11) also serves as a tipping point for the hinge. In addition, said tab (11) causes a clip when interacting with the protrusion (12), which serves as a warning to the user indicating that a correct opening has occurred.

[0032] The protrusion (12) has, on its outer face, a cleft (13) defined in its lowest sector, more specifically in the area intended to be in contact with the tab (11) when the lid (2) is open at an angle of approximately 180, as shown in FIGS. 5 to 7. In this way, the outermost end of the protrusion (12) is housed inside said cleft (13), helping to reduce the tension generated in the binding strips (8).

[0033] When the 180 opening of the lid (2) is exceeded, up to approximately 210 as shown in FIG. 8, the protrusion (11) slides towards an upper end of the cleft (13) until it comes out of it, generating a warning sound.

[0034] The ring (1) is, before the first opening of the cap, connected to the lid (2) by frangible bridges (14) which are intended to break during the first opening of the lid (2). These frangible bridges (14) make up tamper-evident seals and connect the top edge of the ring (1) and the bottom edge of the perimeter wall (4).
