Definitions

  • the present invention relates to a stopper for a container.
  • the invention relates more particularly to a cap which is inseparable from the container even when the cap is open, in particular a cap usable on a brick-shaped container, for example made of cardboard.
  • a container such as a cardboard carton can be provided with a neck onto which a cap is screwed.
  • the neck can be attached to the cardboard carton, for example by gluing.
  • the term container here refers to any kind of container, without limitation of shape or use.
  • the stopper comprises, for example, a stopper body comprising a tubular skirt and a plate connected at its periphery to the skirt and intended to cover the opening of the neck.
  • the skirt comprises a thread arranged inside, intended to engage with a complementary shape of the neck.
  • the skirt is often extended by a tamper-evident ring designed to engage with a collar on the neck.
  • the tamper-evident ring is connected to the skirt by bridges between which extend through dividers.
  • bridges between which extend through dividers.
  • inseparable caps comprise the same elements as conventional caps except that the cap body is permanently connected to the tamper-evident ring by means of connecting arms.
  • These connecting arms are shaped by their length in such a way as to allow the cap body to move axially away from the tamper-evident ring, to detach from the neck and to be able to tilt towards an open position which allows the fluid contained in the container to be poured through the neck.
  • plugs are described in the documents WO2020/227813A1 And JP2014-061929A .
  • the invention aims to provide a cap and a cap assembly that is more practical, while complying with regulations and minimizing manufacturing costs.
  • the flow of liquid is no longer hindered by the cap body.
  • the cap is therefore convenient to use. The user only has to unscrew the cap and then rotate the cap to the intermediate opening position, or the fully open position, until the cap body is immobilized by means of the locking finger. Then, the user can freely pour the liquid contained in the container without having to hold the cap body.
  • the invention also provides a brick-shaped container, characterized in that it is equipped with a stopper assembly according to one of the preceding characteristics.
  • a container 10 is shown equipped with a cap assembly 12 according to the invention.
  • the container 10 is here of the cardboard brick type made by folding and gluing.
  • the invention is also suitable for other types of containers.
  • the cap assembly 12 is attached to an upper wall 14 of the container 10 which has an opening 15.
  • the cap assembly 12 is shown in more detail in the figures 2 and following. Here it has a threaded neck 14 and a cap 16 designed to be screwed onto the neck 14.
  • an axial orientation along the main axis A1 of the cap assembly 12 will be used, without limitation, i.e. along the axis of the neck 14, from bottom to top, considering the Figures 2 and 3 .
  • the cap assembly 12 is first described when it occupies its closed position on the neck 14, as shown in the figures 2, 3 And 4 .
  • the neck 14 is here provided at its lower axial end with a radial collar 18, or base, which allows the cap assembly 12 to be fixed to the container 10 in a hermetic manner.
  • the stopper 16 comprises a stopper body 20 comprising a substantially tubular skirt 22, along the main axis A1.
  • the skirt 22 is provided on its internal axial wall with threads 24 which allow it to engage with the neck 14 of the container 10 by screwing.
  • the cap 16 also includes a tamper-evident ring 26 which is retained axially on the neck 14 by a retaining rib 28.
  • the cap body 20 and the tamper-evident ring 26 are made in a single piece by injection of plastic material into a mold.
  • the tamper-evident ring 26 is connected to the skirt 22 by breakable material bridges 29. Unscrewing the cap body 20 relative to the neck 14 causes the material bridges 29 to break to allow the opening of the cap 16 and to give access to the neck 14.
  • the tamper-evident ring 26 comprises clamping elements 31 against the neck 14 to slow the rotation of the cap 16 on the neck 14 and to allow it to be held in a determined angular position.
  • the tamper-evident ring 26 here comprises, over a portion of its circumference, a connecting portion 30 of generally trapezoidal shape which extends upwards.
  • This connecting portion 30 therefore has an axial dimension greater than the axial dimension of the tamper-evident ring 26 over the rest of its circumference.
  • the connecting portion 30 extends, on each side of its apex 32, by two connecting arms 34, 36 which are each connected to the cap body 20 by a hinge 38, 39.
  • the hinges 38, 39 are here arranged close to the bottom wall 40 of the plug body 20.
  • the skirt 22 therefore comprises a notch 41 which generally follows the shape of the connecting portion 30.
  • the notch 41 comprises in particular two inclined edges 43, 44, on either side of the connecting portion 30.
  • hinges 38, 39 in the form of a thin veil of material to allow the pivoting of the cap body 20 relative to the tamper-evident ring 26, around a transverse pivot axis T1.
  • the pivot axis T1 is here generally tangent to the cylinder formed by the skirt 22.
  • the two connecting arms 34, 36 delimit between them a notch 42 whose bottom 45 corresponds to the top 32 of the connecting portion 30.
  • the cap body 20 comprises a locking finger 46 which is arranged between the two connecting arms 34, 36 and which extends axially towards the tamper-evident ring 26, here downwards.
  • the locking finger 46 comprises a free end edge 48 which is here substantially parallel to the pivot axis T1 and which extends in the vicinity of the apex 42, at the bottom of the notch 42, when the cap body 20 is in its closed position.
  • the transverse dimension of the locking finger 46 is here slightly less than the transverse dimension of the notch 42.
  • the locking finger 46 extends axially in the extension of the connecting portion 30, that is to say that the external axial surface 50 of the locking finger 46 is flush with the connecting portion 30 and with the rest of the skirt 22.
  • the upper section of the neck 14 comprises an external peripheral groove 52 which is delimited downwards by a lower rim 54 and upwards by an upper rim 56 intended to cooperate with the locking finger 46 in opening positions of the cap 16, as will be described subsequently.
  • the neck 14 comprises at its upper axial end a sealing lip 58 which is designed to be compressed against a sealing element of the cap 16, here an internal axial skirt 60, in the closed position of the cap 16 against the neck 14.
  • the sealing lip 58 extends in a generally radial plane, but slightly inclined towards the inside of the neck 14.
  • the sealing lip 58 projects slightly towards the inside of the neck 14. the outside of the neck 14, thus forming the upper edge 56 of the outer peripheral groove 52.
  • the cap body 20 can be unscrewed by a user. Since the cap body 20 remains connected to the tamper-evident ring by the hinges 38, 39, at the end of the unscrewing the cap body 20 is pivoted about the pivot axis T1 to an intermediate opening position O1, which is illustrated by the figures 5 And 6 .
  • the intermediate opening position O1 here corresponds to a pivoting of the cap body 20 by a first angle a1 of between 90 and 100 degrees, preferably 95 degrees, relative to its closed position.
  • the cap body 20 is held in the intermediate opening position O1 by the locking finger 46 which pivots with the cap body 20 and which comes to bear by its free end edge 48 against a first bearing zone on the neck 14.
  • the first bearing zone is constituted here by the lower edge 54 of the outer peripheral groove 52.
  • the plug body 20 is pivoted about the pivot axis T1 to a fully open position O2, which is illustrated by the Figure 7 .
  • the fully open position O2 here corresponds to a pivoting of the cap body 20 by a second angle a2 greater than or equal to 150 degrees, preferably substantially equal to 170 degrees, relative to the closed position.
  • the cap body 20 is held in the fully open position O2 by the locking finger 46 which comes to bear via the outer axial surface 50 against a second bearing zone on the neck 14.
  • the second bearing zone is constituted here by the upper rim 56 of the outer peripheral groove 52.
  • it is an end portion of the outer axial surface 50, located in the vicinity of the free end edge 48, which comes to bear against the upper rim 56.
  • the stopper body 20 is released from the neck 14 to allow the pouring of a fluid through the opening 15 of the container 10.
  • a first radial distance d1 from the pivot axis T1 to the free end edge 48 of the locking finger 46, is slightly greater than a second radial distance d2 to the lower rim 54 of the outer peripheral groove 52.
  • cap body 20 is able to pivot in the opposite direction, from each of its opening positions O1, O2 to the closing position.
  • the cap 16 and the cap assembly 12 according to the invention allow two indexed opening positions to be available. This allows the cap assembly 12 according to the invention to be implemented in many different container configurations, in particular for brick-shaped containers as in the Figure 1 where it is important to be able to maintain the open position when pouring liquid from the container.
