Definitions
- the invention relates to a device for plugging a container with a threaded neck, a threaded neck which can be plugged by such a device and a container comprising such a neck plugged by such a device.
- a closure device comprising a stopper associated with a tamper-evident ring mounted on the neck in such a way that it cannot not be removed.
- unscrewing the plug necessarily results in a break in the connection between the plug and this ring.
- notches provided respectively on the tamper-evident ring and on the neck remain in abutment "point on point", which induces a radial expansion of the ring which can result in a plastic deformation of the latter. This is very unsightly.
- the notches provided on the threaded neck protrude radially outwardly and can be damaged, for example during handling prior to the filling of a bottle, which reduces the effectiveness of a sealing ring.
- the invention more particularly intends to remedy by proposing a new closure device wherein the cap screwing torque is lower than 1 'state of the art while, once in place,' the tamperproof ring is retained with certainty on the container neck.
- the invention relates to a device for closing a container with a threaded neck which comprises a stopper, comprising a bottom and an internally threaded skirt capable of cooperating with an external thread of the neck, and a tamper-evident ring connected by frangible means to this skirt and provided 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 plug. Thanks to the orientation of the notches of the tamper-evident ring, they do not have to slide on corresponding notches of the neck when the cap is screwed on since they are not oriented radially towards the central axis of this device.
- the device incorporates one or more of the following characteristics:
- the notches are formed on an annular surface of an internal projection of the tamper-evident ring.
- This annular surface advantageously extends in a plane, generally perpendicular to a central axis of the device. In particular, this annular surface can be generally parallel to the bottom of the plug.
- the projection is provided with a generally frustoconical surface converging towards the bottom of the plug. This surface can cooperate with a corresponding surface of the neck to form a radial expansion ramp of the tamper-evident ring when the device is placed on the neck of a container.
- the notches are inclined, each notch having a first face oriented towards the annular skirt of the stopper and a second face inclined relative to this first face.
- the inclined nature of the notches allows movement of these notches relative to the corresponding notches provided on the neck in a direction of screwing of the device but is opposed to a movement in a direction of unscrewing.
- the invention also relates to a threaded neck of a container which can be plugged with a device as previously described and which is characterized in that it comprises notches oriented opposite the outlet of the neck relative to an external radial flange of this one.
- Such a neck can be easily molded and the orientation of the notches that it comprises allows them to be operational as soon as traction is exerted on a closure device in a direction of opening of the container, these notches not having tendency to radially expand a tamper-evident ring.
- this collar incorporates one or more of the following characteristics:
- the notches are formed on an annular surface of the collar extending in a plane generally perpendicular to a central axis of the neck.
- the flange is provided with a frustoconical surface converging in the direction of the opening of the neck, this surface forming a ramp for radial expansion of a tamper-evident ring when a closure device is put in place.
- each notch is inclined, each notch having a first face parallel to a central axis of the neck and a second face inclined relative to this first face.
- the invention finally relates to a container comprising a neck as previously described, blocked by a device such as previously described.
- FIG. 1 is an axial section in principle of a closure device and the neck portion of a container according to one invention before mounting the device on the neck;
- - Figure 2 is a view similar to Figure 1 when the device is being mounted on the neck;
- - Figure 3 is a view similar to Figure 2 when the device is mounted on the neck and
- FIG. 4 is a partial section along the line IV-IV in Figure 3.
- the container 1 shown in FIGS. 1 to 3 is a bottle, the neck 2 of which is produced in one piece with the main 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, except that the thread 4 is inclined.
- the outlet of the neck 2 that is to say the disc-shaped surface constituting the border between the inside volume of the neck 2 and the outside of the container 1.
- the neck 2 is provided with a defined external collar 5 between a generally frustoconical surface 5a converging in the direction of the outlet 2a. and an annular surface 5h generally perpendicular to the axis X 2 .
- P 5 the geometric plane of the surface 5b. This plane is perpendicular to the axis X 2 .
- the surface 5b is provided with notches 6 which extend in the direction of a lower flange 7 and the main part 3 of the body 2.
- the notches 6 are thus opposite the outlet 2a. relative to the collar 5.
- the closure device 10 intended to be mounted on the neck 2 is centered on an axis X 10 .
- the device 10 comprises a plug 11, the bottom 12 of which is extended by a cylindrical skirt 13 provided with an internal thread 14 capable of cooperating with the thread 4.
- the bottom 12 is also provided with a second skirt 15 intended to bear against the internal cylindrical surface 2 h of the neck 2 in the vicinity of the outlet 2 a.
- the skirt 15 is equipped with an external bead 15a intended to improve the sealing of the support of the skirt 15 against the surface 2b.
- the device 10 also comprises a tamper-evident ring 16 connected to the plug 11 by frangible or breakable zones 17 defined between openings 18 formed between the ring 16 and the plug 11.
- the shape of the openings depends on a choice of design and n is not limited to that shown. According to a variant not shown of the invention, the openings 18 can extend in the direction of the bottom 12 of the plug 11.
- the ring 16 is equipped with an internal ring 19 defined between a frustoconical surface 19a converging towards the bottom 12 and an annular surface 19b generally perpendicular to the axis X 10 .
- P 19 the geometric plane of the surface 19b. This plane is generally perpendicular to the axis X 10 and parallel to the bottom 12 of the plug 11.
- the surface 19h is provided with notches 20 which extend in the direction of the neck 12 and whose geometry is such that 'They can cooperate with the notches 6 provided on the neck 2.
- the notches 20 and 6 are inclined. More specifically, the notches 6 each have a face 6a generally parallel to the axis X 2 and a face 6b inclined relative to the face 6a. Similarly, the notches 20 have a face 20a generally parallel to the axis X 10 , that is to say oriented in the direction of the skirt 13, and a face 20b inclined relative to this face 20a. Given the inclined geometry of the notches 6 and 20, these are compatible with a screwing movement of the device 10 on the neck 2, this resulting in a displacement in the direction of the arrow F 3 in FIG. 4, but s oppose a unscrewing movement as shown by arrow F 4 , the surfaces 20a then coming to bear against the surfaces 6a.
- the height h s of the notches 6 can be between 0.3 and 0.5 mm, as well as the height h 20 of the notches 20.
- the invention has been shown with a neck 2 and a closure device 10 provided with notches over the entire periphery of the collar 5 and of the rod 19. It is however possible to provide notches on only part of one or of these two protruding organs.
- the notches 6 are provided so that they can be removed from the mold by the principle known as "shells".
- the neck 2 can be in one piece with the main part 3 of the container 1 or attached thereto.
