Definitions

  • the present invention refers to a closure assembly for containers of the type that comprise a neck or neck and where the cap is always attached to said neck, both when the container is closed, and when it is open to dispense or pour the liquid or product contained within.
  • the closure assembly of the invention comprises, on the one hand, a neck and, fixed to it in an inseparable way during use, a closing cap by pressure and capable of, in the open position, remaining open at an angle of up to at least 180 ° that facilitates the extraction of the liquid or product contained in its interior without said stopper becoming an obstruction for its exit.
  • this type of plug has some drawbacks. Among them, it is worth mentioning the fact that, due to the fact that the closing lid cannot be removed because it is attached at the bottom to the neck of the container, sometimes the opening of said lid is not enough and the product (generally liquid) contained in the container stumbles or finds it difficult to leave the interior.
  • plugs of this type appeared in the state of the art but which incorporated means to keep the lid open at a certain angle, that is, both to ensure an opening position and a minimum degree of it in order to facilitate the extraction of the contents of the container in a comfortable way for the user.
  • stopper is that shown in ES2268082T5, which describes a plugging device such that a lid is articulated on a skirt by a double hinge system but in which an anchor point formed by a extension of the rear part of the upper surface of the lid itself and a heel formed by a vertical extension of said skirt and located between the two hinges.
  • the upper extension of the same approaches the aforementioned heel, reaching a point of friction with it when the lid is already in an opening position of approximately 180 °, point from the which, if you want to continue opening, it is necessary for the user to exert a force that forces said extension of the lid to move to an opening position greater than 180 °, at which time the cover is secured in said position, since by itself, without the user forcing it in the opposite direction again, it is not able to overcome the resistance of said friction point.
  • This system although it fulfills the function for which it has been designed, that is, to guarantee and ensure the opening of more than 180 ° of the lid, it can suffer from a significant problem. Specifically, this problem is that the upper part of the bead, intended to rest on the radial surface of the neck of the bottle, does not always rest in the same way or at the same point, since this will depend on how said bead is positioned with respect to the said neck, that is, the angle of rotation applied by the bottling head during assembly, since once the assembly is in place, it must remain fixed to prevent its rotation, that is, so that the user cannot rotate it.
  • said bead is partially supported on a thread.
  • this does not always happen in the same way, because depending on how the skirt on which the lid is articulated is located, the heel may rest on points of different heights of the crest of said thread, that is, on thread ridges of different heights.
  • said length or height of the heel that allows support on the upper edge of the neck of the container for the exchange of forces with the neck of the container, has the disadvantage that it can also constitute a support point during the closure of the lid. and, therefore, carry out an exchange of forces during said closing operation. That is, the contact between the heel and the upper edge of the neck of the container can hinder the closure, making it more uncomfortable for the user, who will not only have to overcome the resistance of the hinge but also that of said contact.
  • said point of support will be formed between the upper end of the heel and the lower part of the upper edge of the neck of the container, which is not a simple support or contact, but both elements may be "locked “Or” jammed “together for a certain moment of time.
  • this locking does not constitute a point of excessive resistance and the user can overcome it in the normal closing maneuver of the cap, it is true that it somehow hinders the aforementioned closing maneuver and, therefore, does not allow an optimal result.
  • this unwanted contact means that the angle and effort that the lid has to make is not controlled, since it will depend on how said contact is made between the upper edge of the neck of the container and the upper end of the bead, while it It is desirable to know exactly what is the response of all the elements and their contribution to both the opening and closing operations.
  • the closure assembly for containers that the present invention proposes solves the problems of the state of the art indicated above, since it not only guarantees that the stopper assembly remains linked to the container and thus avoid waste, but also allows a convenient and practical opening and closing of the lid, while providing a reliable, resistant and easy-to-manufacture fixing system for the same in maximum opening.
  • the cap that is part of the closure assembly of the invention also includes a guarantee seal that shows that the cap has been tampered with, that is, that the container has been opened. This, however, is carried out without entailing the generation of any residue, that is to say, said seal remains attached to the body of the cap after it has been removed to allow opening.
  • the closure assembly for containers of the present invention comprises a neck and a cap where:
  • the neck in turn comprises:
  • a circumferential top shoulder that maintains a constant height relative to the platform and the top edge of the container neck.
  • the plug in turn comprises:
  • a ring-shaped lower skirt A ring-shaped lower skirt; Y
  • a cover located superiorly on said skirt comprising, on its lower face, closure means that cooperate with the upper edge of the neck of the container for closing the container itself and, on its upper face, a tab formed by the extension of the rear part of said upper face;
  • a guarantee seal that shows the use of the closure and that once opened does not generate waste by being attached to the cap.
  • skirt and lid are hinged together thanks to two elastic strips that, at their upper end are attached to the lid and, at their lower end, are attached to the skirt.
  • the skirt of the cap is mounted on the neck of the container between the upper shoulder and the lower shoulder, in such a way that their separation is very difficult.
  • closure for the container of the invention provides an anchor or friction point that sets an opening degree of at least 180 ° of the lid with respect to the neck of the container, so that to overcome it both in the The opening and closing maneuver of the lid is necessary for the user to exert a force that overcomes the resistance created by said point.
  • This anchoring or friction point occurs between the tongue formed by the extension of the rear part of the upper face of the lid and a point of the skirt and is located between the two elastic strips on which the skirt and the lid hinge.
  • said point of anchoring or friction of the skirt is constituted by a heel formed by the vertical extension of the area of said skirt located between the elastic strips, and where said heel has a height such that its upper or free end is located substantially below the upper edge of the neck of the container to avoid the aforementioned problems of the state of the art.
  • the lid flap approaches the heel of the skirt, reaching the referred friction or anchoring point with it when the lid is already in a opening position of approximately 180 °, point from which, if you want to continue opening, it is necessary for the user to exert a force that forces said tab to move to an opening position greater than 180 °, at which time the The lid is secured in said position, since by itself, without the user forcing it again in the opposite direction, it is not capable of overcoming the resistance of said anchoring point or friction with the heel of the skirt.
  • the lid remains open at an angle of at least 180 °, remaining supported by the tongue on the heel, so that at that point there are forces of action F and reaction F ' such that the first is exerted by the tongue on the heel, which forces the skirt to rest exclusively on the upper shoulder of the neck and not on the upper edge of the neck as was the case in the state of the art, said shoulder being located at considerable distance from the upper edge of the neck, the part of the bottle that returns the corresponding reaction force F ⁇
