Definitions

• the invention relates to a device for capping a container and to a container provided with such a device.
• a plastic closure device comprising a cap articulated on a skirt, itself provided to be immobilized around this collar.
• a breakable strip or bridges can connect the stopper to the skirt before the first opening of the bottle.
• the cap When the cap is tilted from its closed position to an open position, it is generally not held relative to the skirt so that, depending on the direction of inclination of the container, it can interfere with the liquid flowing from the neck.
• Such a stopper can also be inconvenient for a user wishing to drink from the neck of a bottle, in particular for applications in the field of mineral waters or drinking yogurts.
• tongues are provided making it possible to constitute a hard point to stabilize a plug articulated in a position making an angle of approximately 90 ° relative to its position for closing a container. In this 90 ° position, the stopper can hinder the spillage of the contents of the container and prevents a user from drinking from the neck. If the plug is tilted to its fully open position, it is no longer held relative to the rest of the device and can, again, be troublesome.
• the invention more particularly intends to remedy by proposing a closure device whose stopper can be effectively maintained in the open position, so that it does not create discomfort when using the liquid contained in the container.
• the invention relates to a device for capping a container provided with a neck, this device comprising a plastic stopper articulated on a skirt intended to surround this neck, characterized in that the stopper carries, in its articulation zone on the skirt, at least one section capable of coming to bear against a heel provided near the upper edge of the skirt, in a configuration for blocking the plug in the fully open position of the device.
• the plug is effectively kept in the fully open position thanks to the cooperation of the aforementioned section and heel.
• the completely open position of the device is that in which the plug is pivoted towards its tilting position in which it frees up the access to the rest of the device and to the neck of the container.
• This fully open position corresponds to an opening angle of the plug substantially greater than 90 °. It is noted that the stable nature of the opening of the stopper is obtained without resorting to a hinge provided with a spring, such a hinge being notably more complicated and more difficult to mold than the mechanism of the invention.
• the device incorporates one or more of the following characteristics:
• the geometry and positioning of the aforementioned section of the plug and the heel are such that the opening angle of the plug, in the fully open and locked position, is greater than or equal to 180 °. In these conditions, the cap is released from the neck when pouring a liquid contained in the container or when a person wishes to drink from the bottle.
• the aforementioned section of the plug is formed between two elastic strips which form a hinge and connect the plug and the skirt.
• two sections are provided on the plug to bear against a heel, these sections being distributed on either side of an elastic strip forming a hinge and connecting the plug and the skirt.
• the support of the plug section on the heel can be obtained by an elastic force exerted by the strips.
• the heel can be formed by a part of the upper edge of the neck.
• the heel can be formed by a one-piece tongue with the skirt and extending upwards from its upper edge.
• this tongue can come to bear, under the effect of a force exerted by the aforementioned section of the plug, against the external radial surface of the neck and transmit to this section a reaction force generated by the neck.
• Such a plug can have a curved external shape to give it a satisfactory aesthetic appearance and avoid the accumulation of liquid or dirt on its upper surface.
• a stopper When such a stopper has been opened, it is sometimes difficult to fold it towards its position for closing the neck of the container because the fingers of a user slide on the edge of the stopper opposite its zone of articulation on the skirt.
• the invention also relates to a closure device of the aforementioned type, the plug of which has a convex external face over the major part of its surface, while this external face is provided with a concave depression formed substantially at the 'opposite the articulation zone of the cap on the skirt.
• the depression formed on the external face of the stopper constitutes a zone for receiving the end of a finger of a user, which makes it possible to exert an effective effort to fold the stopper, limiting the risk that the user's finger slips relative to the external surface of the cap.
• the surface state of the depression is different from the surface state of the convex part of the external face of the plug.
• the depression has a rougher surface than the convex part.
• the coefficient of friction of the user's finger with this depression is relatively large, which further limits the risks of slipping.
• the depression is advantageously connected to an upper face of a nose projecting radially from the edge of the stopper, this nose allowing the opening force of the device to be exerted on the stopper.
• the invention also relates to a container provided with a neck and equipped with a closure device as previously described.

• the skirt 12 is provided with an internal rib 121 intended to cooperate with an external annular flange
• a depression 113 is provided in this face 111, opposite the zone 14, this depression 113 being concave, that is to say forming a hollow relative to the main part 112. This depression 113 constitutes a natural zone of exerting an effort on the plug 11.
• the depression 113 is provided rougher than the main part 112 of the face 111, so that the force F can be exerted without risk of slipping of the finger of a user.
• the surface 113 can be grained or striated.
• the upper face 116 of the nose 115 extends the depression 113, so that the surface on which the force F can be exerted is increased by the same amount.
• the plug 11 is also provided with a projection 117 extending substantially opposite the nose 115 relative to the axis XX ', that is to say in the zone 14.
• the projection 117 comes to rest from the outside against the tongue 122 under the effect of an elastic force F 5 exerted by the strips 15 and 15'. Due to this effort F 5 , the tongue 122 is pressed against the external radial surface 22 of the neck 2, near its upper edge 23, this surface 22 exerting a reaction force F 6 on the projection 117, the direction and the intensity of the forces F 5 and F 6 being such that a blocking of the plug 11 is obtained in the position of FIGS. 4 to 6. In the position of FIGS.

• This tongue 122 extends, from the skirt 12, to above the geometric axis AA ′ of articulation of the plug 11 on the skirt 12.
• the angle of opening ⁇ of the plug 11 is greater than 180 °, so that access to the neck 2 is clearly cleared, while even the plug 11 is provided with an internal skirt 118.
• the plug does not risk hindering a user who uploads content from the bottle, whatever the orientation of the cap 11 around the axis XX '.
• the stopper 11 does not interfere with a person wishing to drink directly from the neck of the bottle 11.
• closure device of the invention has the particular advantage of being able to be molded in the configuration of FIGS. 1 and 2 , that is to say in closed configuration, configuration in which it can be directly mounted on the neck 2 of the bottle 3.
• a molding in closed configuration allows a high density of imprints in the manufacturing mold.
