Definitions

  • the present invention relates to a captive cap destined for the closing of a screw-neck container. More specifically, the captive cap is of the type which comprises a ring for the retaining thereof to the container and articulable arms that enable the cap to remain linked to the retaining ring while open.
  • Captive caps comprising a ring attached to the bottle and with arms linking the removable section with said ring are well-known in the state of the art. This makes it easier for the caps to be recycled together with the plastic of the bottles, instead of polluting the planet, for example by ending up in the sea via the sewer systems.
  • the arms extend over more than half the circumference of the cap, in such a way that the removable portion of the cap can be displaced to an open position without rotation, and remains in this position due to the resilience of the arms, with no need for locking.
  • the joint that acts as a hinge between the arms and the removable portion is not sized so that the removable portion can remain easily in the open position, but the user must force the same for this to be possible.
  • this type of cap might be improved in view of a cap retaining movement that is more convenient for the user.
  • the present invention provides a captive cap for a screw-neck container, comprising a cap shell with an internal thread sized to be screwed onto and unscrewed from the neck of the container, a ring for the retaining thereof to the container and two articulable arms which at their forward extremities are linked to the cap shell and at their rearward extremities are linked to the ring.
  • the cap shell comprises a capping wall and an annular wall, hermetically linked together, it being the annular wall that comprises the internal thread, and the capping wall that covers the container.
  • the captive cap may be positioned in the space in countless ways, but in order to facilitate the explanation and the understanding of the invention, it will be supposed hereinafter that the cap is positioned as it would be when screwed onto a bottle resting on its base, that is, with the cap shell above the ring, its upper extremity and its lower extremity being thus defined.
  • the separations produced between said cap shell, said ring and said articulable arms at the time of opening the cap are defined first by an upper frangible line, defining the separable section of the cap shell with regard to the ring and with regard to the articulable arms, and which extends circumferentially between 210° and 340°, while in the remainder of the circumference a frontal separation of between 150° and 20° is defined between the frontal extremities of the articulable arms.
  • the captive cap is characterised by the fact that the lower frangible line comprises a recess located at said frontal separation and facing the cap shell.
  • the rigidity and resilience of said joints is reduced; they can therefore be bent more easily and the tendency of the cap shell to return to its initial position is avoided.
  • This characteristic is combined with a sufficient length of the articulable arms to enable the threaded section to be displaceable to the side of the rearward extremities of the arms, with no need to rotate it round any spatial axis.
  • This combination of characteristics enables the threaded section to remain in a face-down position when open, without the user having to force it for it to remain in said position, and preventing contaminant particles from falling therein.
  • the recess comprises a horizontal upper section centred at said frontal separation.
  • the upper section coincides on the same plane as the upper frangible line.
  • the recess further comprises two oblique sections, which may be vertically defined, or preferably sloping, with a gradient of less than 90°. In this last case, the preferred gradient is 45°. The fact that they are sloping facilitates the coupling of the recess when closing the cap once again.
  • the upper section extends circumferentially between 10° and 90°.
  • each of the horizontal separations that is, on a horizontal plane
  • the upper frangible line extends angularly at between 260° and 300°
  • the upper section extends angularly at between 30° and 60°. Consequently, each of the horizontal separations between the extremities of the upper section of the recess and the extremities of the upper frangible line can extend angularly at between 15° and 20°.
  • the upper frangible line extends angularly at 270°, while the upper section extends angularly at 60°. Consequently, each of the horizontal separations between the extremities of the upper section of the recess and the extremities of the upper frangible line extend angularly at 15°.
  • the upper frangible line extends angularly at 262°, while the upper section extends angularly at 60°. Consequently, each of the horizontal separations between the extremities of the upper section of the recess and the extremities of the upper frangible line extend angularly at 19°.
  • the lower frangible line preferably extends angularly at between 230° and 320°. In a possible specific embodiment, the lower frangible line extends angularly at 300°. In another possible specific embodiment, where the extension of the articulable arms is less, the lower frangible line extends angularly at 240°.
  • the ring comprises at least one cut-out, centred at said rearward separation and below the upper frangible line. Preferably, this coincides on the same plane as the lower frangible line.
  • This cut-out enhances the hinge function performed by the joints between the rearward extremities of the articulable arms and the ring, making them less rigid and resilient when the cap shell is separated from the container. In other words, this cut-out enables said joints to be distorted with greater ease. On displacing the cap shell to one side of the container, said joints become twisted and do not attempt to return to their initial position, the cap shell remaining in an open position.
  • the cut-out extends angularly at between 10° and 90°, while each of the separations between the extremities of the cut-out and those of the lower frangible line extend at between 10° and 85°. Still more preferably, when the lower frangible line extends angularly at between 230° and 320°, the cut-out extends angularly at between 20° and 30°, while each of the separations between the extremities of the cut-out and those of the lower frangible line extend angularly at between 15° and 35°.
  • the cut-out when the lower frangible line extends angularly at 300°, the cut-out extends angularly at 28°, while each of the separations between the extremities of the cut-out and those of the lower frangible line extend angularly at 16°.
  • the height of the articulable arms defined as the axial separation between the upper frangible line and the lower frangible line along the length of the articulable arms, this 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 vary, provided that they maintain a sufficient distance between each other at the area where they overlap to form the articulable arms.
  • the geometry of the articulable arms is symmetric, with regard to a sagittal plane of the ring.
  • Figure 1 portrays the frontal view of the present embodiment, showing the following:
  • the recess (21) comprises a horizontal upper section (21A) centred in said frontal separation (31), and two oblique sections (21i, 21i') at each side of the upper section (21A), these having a slope of 45°.
  • FIG 2 portrays the rear view of the present embodiment, where the rearward extremities (32A, 32B) of the two articulable arms (3A, 3B) may also be seen, linked to the ring (2), these defining the rearward separation (32).
  • this rearward separation (32) we can see the cut-out (22), centred in, and in this embodiment, coinciding on the same plane as, the lower frangible line (20).
  • the cap shell (1), the ring (2) and the articulable arms (3A, 3B) are linked by one or more regularly- or irregularly-distributed bridges (10', 20'), whose dimensions are designed to be easily torn by a user when unscrewing the cap shell (1).
  • the frangible lines (10, 20) and the respective bridges (10', 20') may be created when moulding the cap or subsequently, by means of cutting operations.
  • Figure 3 portrays laterally a condition of the captive cap where the cap shell (1) is separated vertically from the articulable arms (3A, 3B) and the ring (2). This position is equivalent to the position adopted by the cap shell (1) when unscrewed from the container. Given that in this embodiment the geometry of the articulable arms (3A, 3B) is symmetric with regard to the sagittal plane of the ring (2), one of the articulable arms (3A) is hidden by the other.
  • Figure 4 portrays another condition of the captive cap, where in this case the cap shell (1) is displaced laterally. This position is equivalent to a possible final open position of the captive cap (1).
  • the joints between the articulable arms (3A, 3B) are twisted or distorted.
  • these joints have less rigidity and less resilience, causing the cap shell (1) to remain unmoving in said final open position, causing no difficulty to the user.
  • the dimensions of the articulable arms (3A, 3B) are suited to be articulated in such a way that the cap shell (1), in its unscrewed condition, is susceptible to be displaced to one side of the neck of the container without rotating on any spatial axis and without returning when released.
