PREFERRED EMBODIMENT OF THE INVENTION

[0036] FIG. 1 shows a cap 1 provided on the neck 20 of a container, in the open position.

[0037] The cap 1 is formed by the articulated joint between two superimposed parts, a lower part 2 and an upper part 3. The lower part 2 comprises gripping means for retention thereof on the neck 20 of the container, both during opening and closing of the cap 1. The upper part 3 comprises an upper base 5 joined to a perimeter wall 7. A transverse visor 9 is provided in said perimeter wall 7, capable of enabling the opening of the cap 1.

[0038] In accordance with the present invention, the visor 9 comprises a flap 10 transverse thereto and in correspondence with a complementary cut-out 4 provided on the upper edge of the lower part 2. Additionally, the flap 10 comprises, on the edge of its inner surface, a cord 11 disposed transversely to the axial axis of the cap 1 for executing the grip of the upper part 3 to the neck 20 of the container.

[0039] According to the described configuration, the cord 11 of the flap 10 goes over the ring of the neck 20 of the container in the closed position, constituting a click that indicates and stabilises said closed position.

[0040] Preferably, the upper base 5 may comprise a cylindrical skirt 21 that emerges from its inner face and is dimensioned for being inserted in the interior of the neck 20 of the container.

[0041] FIG. 2 shows a front view of the cap 1 in the closed position. As can be observed, said cap 1 consists of a substantially cylindrical body formed by the articulated joint between the lower part 2 and the upper part 3. Thus, the correspondence of the flap 10 of the upper part 3 with the cut-out 4 of the lower part 2 completes said cylindrical body of the cap 1.

[0042] According to a preferred embodiment and as shown in FIG. 2, the upper base 5 may have a diameter greater than the perimeter wall 7 of the upper part 3, such that said upper base 5 defines a rim which enables the use of mechanical cones in the capping stage. Thus, the positioning of the upper base 5 at the top end of the diametrical recess of said upper base 5 with respect to the perimeter wall 7, allows an industrial distribution of 80,000 bottles per hour in bottling lines.

[0043] FIG. 3 shows the rear part of the cap 1, wherein the upper 3 and lower 2 parts are articulated. As can be observed, two pairs of vertical slots 12 have been made in the perimeter wall 7, disposed parallel to the axial axis of the cap 1 and defining the formation of two joining strips 13 between the two parts 2, 3. Said strips 13 execute the articulation of the parts 2, 3.

[0044] As shown in FIG. 3, the lower part 2 may comprise a ridge 6 disposed between the strips 13.

[0045] FIG. 4 shows the interior of the rear part of the cap 1. As can be observed, on their inner face, the strips 13 may include a first perimeter relief 14 that reduces the inner diameter of the cap 1. By reducing the interior area of the cap 1, dust is prevented from entering the interior of the container.

[0046] Likewise, as shown in FIG. 4, the ridge 6 may include a second perimeter relief 15 to reduce the inner diameter of the cap 1. Thus, the cap 1 reduces the inner area thereof, improving the closure of the container and, therefore, preventing dust from entering the interior thereof.

[0047] According to a preferred embodiment, and as shown in FIG. 5, the upper part 3 may comprise two recesses 15 provided on the outer edge of its upper base 5 and a pair of perimeter slots 14 in said recesses 15.

[0048] As can be observed, the perimeter slots 14 define the formation of a joining tab 16 with each of the strips 13, wherein said tabs 16 are dimensioned so as to provide a continuous perimeter edge on the upper base 5. By maintaining the diameter of the upper base 5 constant, the invention makes it possible to centre the cap 1 on the capping heads, thereby facilitating the manufacture of containers.

[0049] Likewise, as shown in FIG. 5, the upper part 3 may incorporate a protrusion 17 between the recesses 15 which allows the cap 1 to be opened more than 180.

[0050] FIG. 6 shows the interior of the front part of the cap 1. As can be observed, on the inner face, the lower part 2 may incorporate a third perimeter relief 18. Said third relief 18 is disposed on a plane below the cut-out 4 and extends, at least, between the ends of said cut-out 4.

[0051] According to a preferred embodiment, and as also shown in FIG. 6, the ridge 6 disposed between the strips 13 may comprise at least one rib 8 joined in a frangible manner to the upper part 3 before the opening of the cap 1. Thus, the invention provides proof of cap 1 inviolability in the articulation zone between the parts 2, 3, as once the cap is opened the rib 8 is broken, informing the user that the cap 1 has been opened.

[0052] FIG. 7 shows a transverse cross section of the cap 1. As can be observed, the upper part 3 comprises a burr 19 on the lower edge of the inner surface of its perimeter wall 7 for coming into contact with the neck 20 of the container. Thus, the invention limits the entrance of dust and/or foreign matter in the zones that are in contact with the consumer's mouth.

[0053] FIG. 8 shows a detailed view of the interior of the upper part 3 of the cap 1. As can be observed, the inner surface of its perimeter wall 7 houses a pair of ribs 22. Each rib 22 is disposed on either side of the flap 10. Preferably, at least one part of each rib 22 is formed on the inner surface of the flap 10.

[0054] FIG. 9 shows a cross-section of a cap 1 wherein a portion of the ribs 22 shown in FIG. 8 can be observed. The ribs 22 improve cap 1 tightness, both before and after opening it. Likewise, they accentuate cap click closure.

[0055] Lastly, in light of this description and figures, the person skilled in the art may understand that the invention has been described according to some preferred embodiments thereof, but that multiple variations may be introduced in said preferred embodiments without detracting from the object of the invention as claimed.
