Definitions

• the invention relates to a device for capping a container and to a container equipped with such a device.
• the invention relates to a device for capping a container provided with a neck, this device comprising a pourer, capable of being permanently mounted on this neck, and a cap capable of being mounted on this neck and / or this pourer being mobile between a first position where it isolates the neck and the pourer from the outside and a second position where it allows access to this neck and to this pourer, the pourer being disposed at least partially at the inside the neck.
• the cap is provided with a skirt extending, in the aforementioned first position and from an internal surface of the cap, up to the interior of the neck.
• This device is characterized in that this skirt carries at least one external bead capable of exerting, in the aforementioned first position and against an internal radial surface of the pourer, a force tending to press this pourer against an internal edge of the neck.
• the upe of the invention compresses the pourer against the neck of the container, which ensures sealing, on the one hand, between the pourer and the neck and, on the other hand, between the upe and the pourer.
• the seal between the spout and the spout is necessary throughout the lifetime of the container while the seal between the cap and the spout is useful as soon as a cover possibly blocking the spout has been removed. ie after the first use of the fluid contained in the container.
• the force concentration obtained thanks to the bead allows a localized and firm support of the pourer against the inner edge of the neck.
• the device incorporates one or more of the following characteristics:
• the aforementioned edge and skirt are generally cylindrical while the force exerted by the skirt on the pourer is centrifugal with respect to an axis of symmetry of the aforementioned edge.
• the bead In the first position, the bead is arranged opposite the edge of the neck, the force exerted by the bead tends to compress a part of the pourer against this edge.
• This pouring compression takes advantage of its deformable nature and provides the desired seal.
• the skirt is equipped with two external beads of support against the internal radial surface of the pourer, the second bead being provided to ensure the clipping between the cap and the pourer after the first use of the container. It is also possible to provide that the nominal outside diameter of the bead or beads is greater than or equal to the diameter of the internal radial surface of the pourer at the aforementioned edge. This ensures that the skirt of the cap tends to radially expand the pourer as soon as it is placed inside the pourer, this expansion preferably occurring at the edge of the neck, which makes it possible to effectively compress the pourer between the bead and the bottleneck.
• the skirt is made in one piece with the cap, in a material harder than the material of the pourer.
• the one-piece nature of the cap and the skirt gives them satisfactory solidity and rigidity, while the fact that the material constituting the skirt is harder than that of the pourer makes it possible to favor a deformation of the pourer when the skirt is pressed. against the pourer.
• the neck, the pourer and the cap are made of plastic material.
• the neck and the cap are made of high or medium density polyethylene while the pourer is made of low density polyethylene.
• the invention also relates to a container for liquid, in particular a plastic bottle, equipped with a closure device as described above.
• a container for liquid in particular a plastic bottle, equipped with a closure device as described above.
• Such container is transportable without risk of leaks before and after the first use of the fluid it contains, and can be easily recycled because it does not include an aluminum-based seal.
• the edge of the neck is filled by the inner end of a generally frustoconical zone of the neck.

• - Figure 2 is a perspective view similar to Figure 1 while the cap is in a second position;
• - Figure 3 is a section along line III-III in Figure 1;
• FIG. 4 is a section along line IV-IV in Figure 1 and
• FIG. 5 is a section on a smaller scale along the line V-V in Figure 2.
• the bottle 1 shown in the figures is a bottle intended to contain milk, produced by blowing a parison of high density polyethylene. Such a bottle is attractively priced while effectively fulfilling its function as a container.
• the neck 2 of this bottle is cylindrical and the or- X 2 -X ' 2 notes its axis of symmetry.
• This neck has a curved generatrix and it defines a generally frustoconical zone 21 whose inner end forms the edge 22 of the neck 2, the zone 21 being extended by a first flange 23 extending radially outward relative to the axis X 2 -X ' 2 .
• a section 24 connects the flange 23 to a second flange 25, itself connected by a second section 26 to the main body 11 of bottle 1.
• the closure device comprises a pourer 3 and an assembly 4 forming a cap made of plastic.
• the pourer 3 is molded from low density polyethylene while the assembly 4, which is in one piece, is molded from high or medium density polyethylene.
• the assembly 4 is therefore made of a more rigid material than that of the pourer 3.
• Other materials can be used for molding the elements 2, 3 and 4, the material of the pourer remaining less rigid than those of the neck 2 and the set 4.
• the pourer 3 is cylindrical and symmetrical about an axis X 3 -X ' 3 merged with the axis X 2 -X' 2 when the pourer 3 is mounted on the neck 2.
• the pourer 3 comprises a portion 31 with a substantially generatrix straight whose edge 32 opposite to the body 11 of the bottle 1 is curved outwards, so that it forms a surface 32e for the flow of milk without contact with the neck 2.
• the part 31 is disposed partially at the inside the neck 2.
• a skirt 33 intended to cover the zone 21 and the flange 23 of the neck 2, the skirt 33 being provided, at its edge 34 distant from the part 31, of an attachment cord 35 intended to come into engagement against a radial surface 23a of the flange 23 opposite the part 21. This allows immobilization by cooperation of shapes of the pourer 3 on the neck 2.
• the cord 35 has a divergent internal face 35a in the direction of the body 11, so that the pourer 3 can be put in place on the neck 2 by elastic snap-fastening by means of an elastic deformation of the skirt 33 when the pourer 3 is pushed on the neck 2 in the direction of the body 11.
• a cover 36 is connected to the part 31 by a zone
• the cover 36a of privileged rupture makes it possible to isolate the interior volume of the bottle 1 as long as it remains in place.
• the cover 36 is integral with a gripping ring 37 in which a user can pass the finger to exert a force F 1 directed opposite the body 11 in order to remove this cover when it is appropriate to use milk contained in the bottle.
• the assembly 4 comprises a ring 41 intended to be arranged around the neck 2, the ring 41 being provided with a hooking cord 42 capable of engaging against a lower surface 25a of the flange 25.
• a hooking cord 42 capable of engaging against a lower surface 25a of the flange 25.
• lower is meant that the surface 25a is oriented downwards when the bottle 1 is placed on a flat surface, its neck being turned upwards.
• the ring 41 also contributes to keeping the skirt 33 in position in engagement with the flange 23.
• the ring 41 is extended in the direction of the body of the bottle 1 by a ring 43 making it possible to hide the transition part between the neck 2 and the body and bottle 1.
• the internal face 42a of the cord 42 is also frustoconical and divergent in the direction of the body 11, which makes it possible to envisage an elastic snap-fastening of the ring 41 on the neck 2.
• the ring 41 is connected by a hinge 44, formed by an elastically deformable thinned zone, to a generally cylindrical cap 45 of which the center axis is denoted X 45 -X ′ 45 .
• the cap is connected by a band 46 to the ring 41 over almost the entire circumference of this ring, the axes X 2 -X ' 2 and X 45 -X' 45 being combined .
• the band 46 is respectively connected by two frangible zones 46a and 46b to the ring 41 and to the cap 45.
• a tongue 46c makes it possible to remove the ring 46 by rupture of the zones 46a and 46b, which allows a pivoting movement of the cap 45 around of the axis X 44 -X ′ 44 of the hinge 44 between the positions of FIGS. 1 and 2.
• the hinge 44 can be associated with bi-stable tongues, which makes it possible to preserve the orientation of the cap 45 in each of the positions shown in Figures 1 and 2.
• the cap 45 is fitted with a tongue or "cap” 451 making it possible to lift it by a force F 2 shown in FIGS. 3 and 5.
• the cap 45 is equipped with a skirt 452 which is cylindrical and centered on the axis X 45 - X '45 .
• the skirt 452 extends in the direction of the internal volume of the bottle 1 from the internal surface 453 of the cap 45 which is oriented towards this internal volume.
• the height H of the skirt 452 measured parallel to the axis X 45 -X '45 is such that in the closed position shown in Figures 1, 3 and 4, the lower edge 454 of the skirt 452 is located below the edge 22 of the neck 2, that is to say on the side of the interior volume of the bottle 1.
• the external radial surface 455 of the skirt 452 is provided with two beads, referenced respectively 456 and 457, which extend radially outward relative to the surface 455.
• the bead 456 is disposed near the edge 454, such so that it is situated at the edge 22 in the closed configuration of the cap 45 and that it is capable of exerting on the internal radial surface 31a of the part 31 a centrifugal force F 3 relative to the axes X 3 -X ' 3 and X 45 -X ′ 45 which are then combined, this effort F 3 tending to compress this part 31 against the edge 22.
• the effort F 3 therefore makes it possible to guarantee sealing on the one hand between the pourer 3 and the neck 2, that is to say between the part 31 and the edge 22, and on the other hand between the pourer 3 and the cap assembly 4, that is to say between the bead 456 and the part 31.
• the bead 456 makes it possible to concentrate the force exerted on the part 31 of the pourer 3 at the edge 22 which further improves the seal obtained.
• the external diameter D x of the bead 456 is chosen to be slightly greater than the internal diameter D 2 of the surface 31a at the edge 22, so that, by simply placing the skirt 452 inside the pourer 3, an effort F 3 of sufficient intensity is obtained.
• satisfactory results can be obtained with a difference between the diameters D x and D 2 of between 0.5 and 1 mm while these diameters are between 20 and 40 mm, preferably of the order of 30 mm.

• the fact that the skirt 452 is in one piece with the cap 45 gives it good rigidity while its cost price is particularly attractive.
• the invention has been described with an assembly forming a hinged cap. It is however applicable with a screwed cap.
