    [0002] Closing cap with extendable hinge for containers
    [0006] The object of the present application is the registration of a closing cap with an extendable hinge for containers.
    [0008] More specifically, the invention is intended to be used in the technical field of packaging food products, and especially beverages or the like, in particular for containers that have an opening in a neck provided with a threaded outer portion, the hinge connecting the Upper cap and lower ring vertically extendable during opening / closing operation.
    [0012] In the sector of packaging food products (solid, liquid, viscous substances, etc.), caps made from plastic material provided with an internal thread that can be threaded in a thread formed in the neck of a container have been used for many years. allowing the contents of the interior of the container to be kept airtight, for example, in the case of a bottle of the type used for bottling beverages, such as mineral water or the like.
    [0014] Although this system used is practical for the user and relatively inexpensive for manufacturers, it is not so attractive from an environmental point of view since the user sometimes discards the body of the bottle independently of the cap, which causes the failure to recycling of the cap, generating a non-degradable and environmentally damaging waste. Document No. ES 1217541 is known in the state of the art, which describes a closing cap that aims to solve the problem previously stated.
    [0016] However, a detected drawback lies in the fact that the ring remains tight in the area of the bottle thread when unscrewing the cap, it ensures that the cap does not rotate and bother when pouring the liquid, but does not prevent the upper cap it closes inadvertently during the pouring of the liquid due to the inclination of the container to facilitate the leakage of the contained liquid, resulting in this annoying aspect for the user as it can cause the liquid to spill.
    [0018] Furthermore, the applicant is not currently aware of an invention that has all the features described in this specification.
    [0022] The present invention has been developed in order to provide a cap that is configured as a novelty within the field of application and solves the aforementioned drawbacks, also providing other additional advantages that will be evident from the description that accompanies continuation.
    [0024] It is therefore an object of the present invention to provide a closing cap with an extendable hinge for containers, in particular intended for containers having an opening in a neck provided with a threaded outer portion, being of the type comprising a lower ring intended to be coupled to the neck of the container and an upper cap provided on its inner wall with a section that has a fastening means, for example, a thread that can be continuous or discontinuous, intended to engage tightly with the threaded outer portion of the opening of the container, the lower ring and the upper cap being articulated to each other by means of a hinged portion. In particular, the invention is characterized by the fact that it includes in the hinged portion a pressure-releasable locking means comprising a window located in a first section of the hinged portion linked to the upper cap (2), the window being defined by a upper edge and two lateral edges facing each other, and a projection that protrudes from a second section of hinged portion linked to the lower ring, with adequate dimensions to be nestable in the window, the upper edge of the window having an inclined ramp and one end of the projection with a termination free of straight edges.
    [0026] Thanks to the arrangement of these locking means, it is possible to keep the body of the upper cap completely open, thus facilitating the extraction of the liquid or to drink directly from the bottle, without the risk that the upper cap closes inadvertently and the liquid or drink can be spilled outside the reception area.
    [0027] In addition, it is worth mentioning that the fact that the projection has a termination, for example, rounded or curved, makes it easier for the projection to slide when it is inserted into the pressure window during the angular movement of the upper cover carried out by the user, being blocked or trapped said projection inside the window.
    [0029] Additionally, it is possible that the lower ring includes retaining means present in a diametral section of the inner edge of the lower ring, being provided to be in contact with the lower part of the outer threaded portion of the neck, the diameter being the minus a quarter of the total circumference of the lower ring and at most three-quarters of the circumference of the lower ring, such that the section of the lower ring where the hinged portion is located is devoid of such retention means.
    [0031] According to another aspect of the invention, the retention means comprise a plurality of flanges separated from one another by interstices, projecting from the inner rim of the lower ring.
    [0033] In an alternative embodiment, the retention means may comprise an elongated extension, projecting from the inner rim of the lower ring, having a contour parallel to a portion of the lower ring.
    [0035] According to another aspect of the invention, 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.
    [0037] In order to facilitate the turning operation (screwing / unscrewing) of the upper cap of the container neck, an outer surface of a lateral face defined on the upper cap has a non-smooth surface, for example a knurled surface.
    [0039] The cap described thus represents an innovative structure with structural and constitutive characteristics hitherto unknown for the purpose for which it is intended, reasons which, together with its practical utility, provide it with sufficient grounds to obtain the privilege of exclusivity that is requested.
    [0040] Other characteristics and advantages of the closure cap object of the present invention will be evident from the description of a preferred, but not exclusive, embodiment which is illustrated by way of non-limiting example in the accompanying drawings, in which:
    [0044] Figure 1.- Shows a perspective view of an embodiment of the closing cap with an extensible hinge for containers according to the present invention in a closed condition;
    [0045] Figure 2.- Shows a detailed perspective view of the hinged portion present in the cap shown in figure 1;
    [0046] Figure 3.- Shows a perspective view of the cap placed in a neck of a container in a closed position;
    [0047] Figure 4.- Shows a perspective view of the cap placed on a container in an intermediate position;
    [0048] Figure 5.- Shows a perspective view of the cap placed on the container in a completely open position; Y
    [0049] Figure 6.- Shows a plan view of the closure cap in an extended condition.
    [0053] In view of the aforementioned figures and, in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be seen in them, which comprises the parts and elements that are indicated and described in detail below.
    [0055] As shown in the attached figures, the closure cap for containers of the invention is in particular designed to close containers that have an opening in a neck (100) that externally includes a threaded 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 of thread (20), which in this case has a discontinuous thread intended to engage tightly with the threaded outer portion (101) of the container opening. The entire plug assembly is made from a single part made from an injection moldable plastic material or by alternative methods such as compression molding.
    [0057] The lower ring (1) and the upper cap (2) are articulated to each other by means of a vertically extendable hinged portion (3) (in a condition in which the container is supported on a horizontal surface), presenting the lower ring ( 1) Retention means (which will be detailed later) present in a diametrical section of the inner rim (11) of the lower ring (1), being provided to be in contact with the lower part of the threaded outer portion (101) of the neck. As can be seen, the diametral section corresponds to approximately half of the total circumference of the lower ring (1), such that a section (12) of the lower ring (1) where the hinged portion (3) is located is devoid of such means retention, so that it allows the flexion of this section (12) in an upward direction (see Figures 4 and 5) when the user carries out the action of unscrewing the upper cap (2), while a section (13) provided with the retention means it is not flexed. Mention that in an embodiment not represented, it is possible that the lower ring is devoid of the aforementioned retention means, since by means of a specific design together with a material with a greater degree of elasticity of the lower ring, an effect is achieved. retainer.
    [0059] In the embodiment shown in the figures, the aforementioned retention means comprise a plurality of flanges (4) separated from each other by interstices, projecting from the inner edge of the lower ring (1), as can be seen in figure 6.
    [0061] In addition, the hinged portion (3) includes a snap-release locking means (described below) specially designed to keep the upper cap (2) hooked on the lower ring (1), in an open position of the upper cap ( 2) when it is mounted on a container, so that the upper cap (2) is in an inverted position with respect to a closed position (see figure 5) in which the upper cap (2) is arranged on the ring lower (1).
    [0063] Going now in greater detail into the aforementioned pressure locking means, they comprise a window located in a first section of the hinged portion linked to the upper cap (2), the window (33) being defined by an upper edge and two facing lateral edges to each other, and a projection (34) protruding from a second section of hinged portion linked to the lower ring (1), having suitable dimensions and complementary to be nestable in the window, the upper edge of the window having an inclined ramp and one end of the projection (34) with a termination free of straight edges that facilitate the locking operation.
    [0065] As can be seen, these releasable locking means are located between two bridge sections (30) formed on each side of the window (34), capable of bending and acting as areas of articulation between the upper cap (2) and the lower ring. (1).
    [0067] Mention that the window is aligned with a fold line (31) with a smaller cross section present in each of the bridge sections (30). Additionally, also that the hinged portion (3) includes a pair of secondary fold lines (32) located on either side of the fold line (31).
    [0069] In the event that the separation of the assembly of the closure cap described in this specification with respect to the body of the bottle is appropriate, for example, in the waste treatment plant, the lower ring (1) can include a pair of zones weaker fracture that are made up of thinner cross sections that facilitate breakage.
    [0071] An outer surface (21) of a lateral face defined on the upper cap (2) has a non-smooth surface, for example, a knurled surface formed by ribs extending from the upper part to the lower part of the upper cap body ( two).
    [0073] Lastly, the closing cap can include a tamper evident seal that can consist of a plurality of breakable connection points (6) arranged along the perimeter edge, which connect the lower ring (1) and the upper cap. (2) prior to separation.
    [0075] The details, shapes, dimensions and other accessory elements used in the manufacture of the closing cap for containers of the invention may be conveniently replaced by others that do not depart from the scope defined by the claims included below.
