Definitions

• the invention relates to the field of containers, generally bottles, the orifice of which is provided with a pourer, typically in the case of the packaging of liqueurs, aperitifs, alcohols.
• pourers are already known, associated with closure caps, which are distinguished in particular by their method of attachment to the neck of the container and by the pouring element itself.
• the pouring element itself, it can either be of fixed configuration, as shown in FIGS. 1 and 2, or of variable configuration, and in particular axially movable as described in patents FR 2,057,345, GB 922,188 , US 3,217,935 and US 4,569,464.
• the pourer can be force-fitted into the neck, the pourer generally being provided with circular sealing ribs as shown in FIG. 2, and described in patents FR 2,057. 345, GB 922,188 and US 3,217,935.
• pourers are associated with a closure cap and are therefore fixed to the neck during crimping of the closure capsule associated with said pourer, and this, by application of an axial force exerted on the head of the closure capsule, an axial force relatively high, which can range from 80 to 100 daN, being necessary for said pourer to be fixed irreversibly to the neck.
• closure caps may be damaged, in particular by buckling of the skirt or alteration of the easy opening means.
• the problem to be solved is therefore to have a pourer whose attachment to the neck requires only a relatively low axial force, typically less than 20 daN, so as to be able to associate said pourer with any type of closure cap, even the least mechanically resistant, taking into account the permanent tendency to reduce the thicknesses of materials and the weight of packaging.
• the pourer associated with a closure cap and intended to be fixed inside a neck of a container, comprises a peripheral skirt provided with a means for sealingly tight at the neck, a pouring element , and a means of temporarily assembling said pourer and said closure cap, and is characterized in that, a) said peripheral skirt comprises a lower part capable of undergoing a radial separation ensuring the fixing of the pourer to said neck, b) said pourer comprises a rigid part able to undergo an axial downward movement, inside said peripheral skirt, by passing, typically irreversible, from a position called high H to a stable position called low B when fixing said pourer and from said capsule to said neck, c) said pourer comprises a means of cooperation of said lower part and of said rigid part capable of transforming the axial displacement of said rigid part into displacement ement radially of said lower part, said axial movement starting only once said pourer placed in said neck, the axial force required by the axial movement of said rigid part relative to said peripheral skirt being greater than that
• the invention solves the problem posed. Indeed, with the means of the invention, on the one hand, the introduction of the capsule and of the associated pourer into the neck requires only a relatively small force Fi, called the introduction force, taking into account the choice of external dimensions of the peripheral skirt relative to the internal dimensions of the neck. On the other hand, the axial movement which follows the introduction of the pourer into the neck certainly requires an axial force F D , called displacement, greater than Fi, so that said axial movement cannot begin before the pourer is not correctly inserted into the neck, but this displacement force FD remains much lower than that required by the capsules with pourers of the state of the art.
• Figure 1 A is a partial view of a capsule (1) with its insert (2) and associated with a pourer (3), in axial section along the vertical axis (11) of the capsule, the pourer being introduced in the neck (9) of a container, the rigid part (6H) of the pourer still being in the high position, before fixing the pourer to the neck and therefore before any axial movement of this rigid part (6).
