Definitions

  • the present invention relates to a captive cap intended to close a container with a threaded neck. More specifically, the cap is of the type that comprises a retaining ring to the container and articulated arms that allow the cap to be attached to the retaining ring while it is open.
  • Captive caps that comprise a ring attached to the bottle and arms that join the removable section with said ring are known in the state of the art. Thanks to this, it is easier for the caps to end up being recycled together with the plastic from the bottles, instead of polluting the planet, for example, ending up in the sea through the sewage system.
  • the arms extend more than half the circumference of the cap, so that the removable section of the cap can be moved to an open position without having to rotate it, and stay in it thanks to the resilience of the arms, without the need to lock it.
  • the joint that acts as a hinge between the arms and the removable section does not it is dimensioned so that the removable section is easily kept in the open position, if not the user must force it to make it possible.
  • this type of cap could be improved with a view to a more comfortable retention movement of the cap for the user.
  • the present invention provides a captive cap for a container with a threaded neck, which comprises a closing casing with an internal thread dimensioned to screw and unscrew from the neck of the container, a retaining ring to the container and two articulated arms that at their front ends they are attached to the closure casing and at their rear ends they are attached to the ring.
  • the closing casing comprises a closing wall and an annular wall, hermetically joined to each other, the annular wall being the one that comprises the internal thread, and the closing wall the one that covers the container.
  • the cap can be found positioned in space in infinite ways, but to facilitate the explanation and understanding of the invention, from now on the assumption is made that the cap is positioned as it would be when be threaded on a bottle that is seated at its base, that is, with the closing casing above the ring, thus defining its upper end and its lower end.
  • the separations that occur between said closing casing, said ring and said articulated arms at the time of opening the cap are defined firstly by an upper frangible line, which defines the separable section of the closing casing with respect to the ring and with respect to the articulated arms, and which extends circumferentially between 210° and 340°, while in the rest of the circumference a front separation between the front ends of the articulated arms of between 150° and 20° is defined.
  • a lower frangible line which defines the separable section of the ring with respect to the closing casing and with respect to the articulated arms, and which extends circumferentially between 180° and 330°, while in the rest of the circumference it remains defined a rear separation between the rear ends of the articulated arms of between 30° and 180°.
  • the captive cap is characterized by the fact that the lower frangible line comprises a recess located in said front separation and projected towards the closing casing.
  • these joints reduce their rigidity and resilience, so they bend more easily and prevent the tendency of the closure casing to return to its initial position.
  • This feature is combined with a length of the articulated arms that is sufficient for the threaded section to be movable to the side of the rear ends of the arms without the need to rotate it in any spatial axis. This combination of characteristics allows the threaded section to be easily maintained in an upside down position in its open condition, without the user having to force it to remain in said position and preventing contaminating particles from falling inside it.
  • the recess comprises an upper section, horizontal and centered on said front separation.
  • the upper section coincides in the same plane with the upper frangible line.
  • the recess also comprises two oblique sections, which can be defined vertically, or preferably inclined with a slope of less than 90°. In the latter case, the preferred inclination is 45°. The fact that they are inclined makes it easier to fit the recess when closing the cap again.
  • the upper section extends circumferentially between 10° and 90°. Since the extension range of the upper frangible line is between 210° and 340°, each of the horizontal separations (that is, in a horizontal plane) between the ends of the upper section of the recess and the ends of the line upper frangible extend angularly between 5° and 30°.
  • the upper frangible line extends angularly between 260° and 300°, while the upper section extends angularly between 30° and 60°. Accordingly, each of the horizontal spacings between the ends of the upper portion of the recess and the ends of the upper frangible line may angularly extend between 15° and 20°. In a possible specific embodiment, the upper frangible line extends angularly 270°, while the upper section extends angularly 60°. Consequently, each of the horizontal gaps between the ends of the upper section of the recess and the ends of the upper frangible line extend angularly by 15°.
  • the upper frangible line extends at an angle of 262°, while the upper section extends at an angle of 60°. Consequently, each of the horizontal gaps between the ends of the upper section of the recess and the ends of the upper frangible line extend angularly by 19°.
  • the lower frangible line preferably extends angularly between 230° and 320°.
  • the lower frangible line extends angularly 300°.
  • the lower frangible line extends angularly 240°.
  • the ring comprises at least one cutout, centered on said rear parting and below the upper frangible line. It is preferably coincident in the same plane as the lower frangible line.
  • This cut enhances the hinge function performed by the joints between the rear ends of the articulated arms and the ring, making them less rigid and resilient when the closure casing is separated from the container. In other words, this cut allows said joints to deform more easily.
  • the cut extends angularly between 10° and 90°, while each of the spacings between the ends of the cut and those of the lower frangible line extend between 10° and 85°. Even more preferably, when the lower frangible line extends angularly between 230° and 320°, the cut extends angularly between 20° and 30°, while each of the separations between the ends of the cut and those of the lower frangible line are They extend angularly between 15° and 35°. In a particular embodiment, when the lower frangible line extends angularly 300°, the cut extends angularly 28°, while each of the gaps between the ends of the cut and those of the lower frangible line extends angularly 16°.
  • the height of the articulated arms defined as the axial separation between the upper frangible line and the lower frangible line along the articulated arms, it is up to 10 mm and preferably between 1 mm and 2.5 mm. It is conceivable to allow the axial position of the frangible lines to be varied, as long as they maintain a sufficient distance from each other in their overlap zone to form the articulable arms.

This position is equivalent to the position assumed by the closing casing (1) when it is unscrewed from the container. Given that in this embodiment the geometry of the articulated arms (3A, 3B) is symmetrical with respect to the sagittal plane of the ring (2), one of the articulated arms (3A) is covered by the other.
