Definitions

  • the invention relates to a device for closing a container with threaded neck, to a threaded neck able to be closed by such a device and to a container comprising such a neck closed by such a device.
  • the closure device is placed in position by screwing the cap, the notches of the tamperproof ring then coming opposite the notches provided on the neck, this ring having to expand radially at the end of screwing in order to pass over a retaining flange of the ring in order to position the notches which are opposite one another.
  • the couple necessary for screwing the cap is relatively high since the notches rub on one another.
  • the notches provided respectively on the tamperproof ring and on the neck remain in abutment “apex on apex”, which induces a radial expansion of the ring which may result in a plastic deformation thereof. This is very inaesthetic.
  • the notches provided on the threaded neck project radially towards the outside and may be damaged, for example during manipulations prior to filling a bottle, which reduces the efficiency of the tamperproof ring.
  • the invention relates to a device for closing a container with threaded neck which comprises a cap, including a bottom and an internally threaded skirt adapted to cooperate with an external threading of the neck, and a tamperproof ring linked by frangible means to this skirt and equipped with notches provided to cooperate with complementary notches provided on the neck.
  • This device is characterized in that the notches of the ring are oriented in the direction of the bottom of the cap.
  • the former can be provided with heights of teeth much less than in the devices of the state of the art, a saving of material thus being able to be made.
  • the device incorporates one or more of the following characteristics:
  • the notches are formed on an annular surface of an internal projection of the tamperproof ring.
  • This annular surface advantageously extends in a plane, substantially perpendicular to a central axis of the device.
  • this annular surface may be substantially parallel to the bottom of the cap.
  • the projection is provided with a substantially truncated surface convergent in the direction of the bottom of the cap. This surface may cooperate with a corresponding surface of the neck to constitute a ramp for radial expansion of the tamperproof ring when the device is positioned on the neck of a container.
  • the notches are inclined, each notch having a first face oriented towards the annular skirt of the cap and a second face inclined with respect to this first face.
  • the inclined nature of the notches allows a movement of these notches with respect to the corresponding notches provided on the neck in a sense of screwing of the device, but opposes a movement in a sense of unscrewing.
  • the invention also relates to a threaded neck of a container which may be closed with a device such as described hereinabove and which is characterized in that it comprises notches oriented opposite the opening of the neck with respect to an outer radial flange thereof.
  • Such a neck may be easily moulded and the orientation of the notches that it comprises allows them to be operational as soon as a traction is exerted on a closure device in a sense of opening of the container, these notches not tending to expand a tamperproof ring radially.
  • this neck incorporates one or more of the following characteristics:
  • the notches are formed on an annular surface of the flange extending in a plane substantially perpendicular to a central axis of the neck.
  • the flange is provided with a truncated surface convergent in the direction of the opening of the neck, this surface forming a ramp for radial expansion of a tamperproof ring during positioning of a closure device.
  • the notches are inclined, each notch having a first face parallel to a central axis of the neck and a second face inclined with respect to this first face.
  • the invention relates to a container comprising a neck as described hereinabove closed by a device as described hereinabove.
  • FIG. 1 is an axial section of a closure device and of the part forming the neck of a container in accordance with the invention, before the device is mounted on the neck.
  • FIG. 2 is a view similar to FIG. 1 when the device is being mounted on the neck.
  • FIG. 3 is a view similar to FIG. 2 when the device is mounted on the neck, and
  • FIG. 4 is a partial section along line IV-IV in FIG. 3.
  • the container 1 shown in FIGS. 1 to 3 is a bottle of which the neck 2 is made in one piece with the principal part 3 of the bottle 1 .
  • the neck 2 is provided with an external thread 4 .
  • X 2 denotes a central axis of the neck 2 , this axis being an axis of symmetry of revolution of the neck 2 , apart from the fact that the thread 4 is inclined.
  • 2 a denotes the opening of the neck 2 , i.e. the disc-shaped surface constituting the boundary between the internal volume of the neck 2 and the outside of the container 1 .
  • the neck 2 is provided with an external flange 5 defined between a substantially truncated surface 5 a convergent in the direction of the opening 2 a and an annular surface 5 b substantially perpendicular to axis X 2 .
  • P 5 denotes the geometrical plane of the surface 5 b . This plane is perpendicular to axis X 2 .
  • the surface 5 b is provided with notches 6 which extend in the direction of a lower flange 7 and the principal part 3 of the body 2 .
  • the notches 6 are thus opposite the opening 2 a with respect to the flange 5 .
  • the closure device 10 provided to be mounted on the neck 2 is centred on a axis X 10 .
  • the device 10 comprises a cap 11 of which the bottom 12 extends in a cylindrical skirt 13 provided with an internal thread 14 adapted to cooperate with the thread 4 .
  • the bottom 12 is also provided with a second skirt 15 intended to come into abutment against the internal cylindrical surface 2 b of the neck in the vicinity of the opening 2 a .
  • the skirt 15 is equipped with an outer bead 15 a intended to improve the seal of the abutment of the skirt 15 against the surface 2 b.
  • the device 10 also comprises a tamperproof ring 16 connected to the cap 11 by frangible or breakable zones 17 defined between openings 18 made between the ring 16 and the cap 11 .
  • the shape of the openings depends on a choice of design and is not limited to that shown. According to a variant of the invention (not shown), the openings 18 may extend in the direction of the bottom 12 of the cap 11 .
  • the ring 16 is equipped with an inner ring 19 defined between a truncated surface 19 a convergent in the direction of the bottom 12 and an annular surface 19 b substantially perpendicular to the axis X 10 .
  • P 19 denotes the geometrical plane of the surface 19 b . This plane is substantially perpendicular to axis X 10 and parallel to the bottom 12 of the cap 11 .
  • the surface 19 b is provided with notches 20 which extend in the direction of the neck 12 and of which the geometry is such that they can cooperate with the notches 6 provided on the neck 2 .
  • Screwing continues until the surface 19 b passes beyond the surface 5 b in the direction of arrow F 2 in FIG. 2, which brings the ring 16 into the configuration of FIGS. 3 and 4 where the notches 10 are opposite the notches 6 .
  • the notches 19 are not stressed radially, this avoiding a risk of rupture or of plastic deformation of the ring 16 .
  • the radial expansion of this ring during this movement is progressive and uniformly distributed about axes X 2 and X 10 as it results from the slide of the surface 19 a on the surface 5 a.
  • the notches 20 and 6 are inclined. More precisely, the notches 6 each have a face 6 a substantially parallel to the axis X 2 and a face 6 b inclined with respect to the face 6 a . In the same way, the notches 20 have a face 20 a substantially parallel to the axis X 10 , i.e. oriented in the direction of the skirt 13 , and a face 10 b inclined with respect to this face 10 a . Taking into account the inclined geometry of the notches 6 and 20 , the latter are compatible with a movement of screwing of the device 10 on the neck 2 , this resulting in a displacement in the direction of arrow F 3 in FIG. 4, but oppose a movement of unscrewing as represented by arrow F 4 , the surfaces 10 a in that case coming into abutment against the surfaces 6 a.
  • the latter may have relatively small heights.
  • the height h 6 of the notches 6 may be included between 0.3 and 0.5 mm, in the same way as the height h 20 of the notches 20 .
  • the invention has been represented with a neck 2 and a closure device 10 both provided with notches over the whole periphery of the flange 5 and of the ring 19 .
  • a neck 2 and a closure device 10 both provided with notches over the whole periphery of the flange 5 and of the ring 19 .
  • the notches 6 are provided so that they can be demoulded by the so-called “shell” principle.
  • the neck 2 may be in one piece with the principal part 3 of the container 1 or connected thereon.
