Definitions

  • the present invention relates to a cap of the type which has a body provided with a pouring nozzle, whereby the bottle contents can be directly consumed, a nozzle which is usually displaced with respect to the centre of the cap body and which is closed by a stopper established at the top of the cap.
  • Document PCT ES02/00425 relates to a cap with tamper seal, which is constituted from a cylindrical body with coupling means on the corresponding bottleneck of the container which incorporates a pouring nozzle, through which the liquid from the bottle is poured or is directly consumed, a nozzle which is closed by a stopper established for said purpose in the top, articulated to the cap body via a bridge by way of a hinge.
  • a single piece is produced which forms the body and the open top, both joined by a hinge bridge.
  • lateral bending means close the top on the cap body, a manoeuvre wherein it is essential that the stopper is introduced in the pouring hole in a precise manner to avoid permanent deformations thereof.
  • a stopper guide consisting of a cylindrical extension, concentric to the stopper and with markedly greater height than it, a guide which has an internal inclined edge which, in contact with the outer periphery of the pouring hole, encourages the guiding and sliding of the stopper inside the pouring hole.
  • the stopper guide firstly impacts against the sector of its inclined surface farthest from the joint (front sector) on the corresponding section of the opening, to progressively increase the surface in contact between the guide and the opening as the top is bent downwards, until it makes contact with the inclined surface of the guide closest to the joint, rear sector, with the corresponding sector of the opening.
  • the initial contact of the front sector of the guide on the opening of the pouring hole determines the gradual positioning of the stopper towards the inside of the pouring hole.
  • the problem arises as a consequence of the ratio between the height of the guide and the height of a stopper being reduced, and that during the progressive sliding of the front sector of the guide in contact with the opening of the pouring hole it is not achieved that the stopper crosses said opening, coming to contact therewith instead of entering the pouring hole, becoming deformed.
  • Document EP-A-1 364 886 which is regarded as the closest prior art and upon which the preamble of claim 1 is based, discloses a cap with a hinged top and an excentric pouring hole.
  • the cap with hinged top which constitutes the object of this invention resolves the aforementioned problem satisfactorily by an optimized design of the stopper guide.
  • the cap after being produced by injection, consists of a body wherefrom there protrudes a pouring hole, out of phase in the upper part, and a hinged top which has said sealing guide which fits inside the pouring hole.
  • the sealing guide in accordance with the design proposed by the invention, favours, in the phase of bending the top towards the body of the cap, still hot after its production by injection, the progressive guiding of the stopper of the top and its subsequent positioning inside the pouring hole, avoiding any unwanted contact during the bending between said stopper and the opening of the pouring hole and, in consequence, any possible deformation of the stopper.
  • the sealing guide is devised with a general cylindrical configuration sectioned by an inclined plane which defines a height of the sealing guide which is progressively decreasing between a front sector of greater height, far from the hinge, and a subsequent section of less height, beside the hinge.
  • the height of the guide, in its highest sector is markedly greater than that of the conventional guides, in the order of 2 1 ⁇ 2 to 3 times the height of the stopper.
  • the height provided for the front sector permits that the guide comes into contact at an earlier point with the external inclined surface of the pouring hole, so that the stopper is positioned with respect to the pouring hole in a position distant from and above said pouring hole and, therefore, with greater margin of manoeuvre with respect to the opening, facilitating its progressive approximation and the perfect coupling of both elements
  • the reduced height of the rear sector of the stopper guide means that it practically does not intervene in the bending movement, the front sector of the guide being that which contacts with the outer surface of the pouring hole, guiding the stopper towards the inside of the pouring hole.
  • the cap with hinged top which constitutes the object of this invention, fundamentally consists of a piece produced after the injection process, which is formed by a body (1) provided with a pouring hole (5), decentred, and a top (2) articulated to the body (1), via a hinge bridge (6), a top which has on its lower surface a stopper (3), which fits inside the pouring hole (5) in the closed position of the top, to obtain the necessary watertightness, and a stopper guide (4), concentric and outside the stopper (3).
  • the stopper guide (4) shows a cylindrical configuration, sectioned by an inclined plane which defines a height of the stopper guide which is variable and progressive, which is of maximum height in the sector (4b) farthest from the hinge area, and at minimum height in the sector (4a) closest to the hinge area.
  • the height of the guide in sector (4b) is markedly greater than the height of the conventional guides, as in this case it is 2 1 ⁇ 2 to 3 times more than the height of the stopper.
  • This configuration allows the stopper guide (4) to come into contact with the pouring hole (5), via sector (4b) in a position wherein the stopper is greatly above and distant from the pouring hole, which allows a greater path to face one another and slide in said pouring hole.
  • the guide (40) had a homogenous height, contacting with the pouring hole (50) in a position of the top (20) with little margin for manoeuvre for the introduction of the stopper in the pouring hole (50) of the body (10).
  • the new morphology of the stopper guide gives the manoeuvre of the cap closure greater scope and margin of distances for the coupling, without damaging contact, between the stopper and the pouring hole.
