  "abstract": "A fixing device for fixing a dispensing member to the neck of a receptacle, the fixing device includes a fixing ring having a bottom skirt engaging a neck of a receptacle, a member for receiving a dispensing member, and a top socket which extends in the direction opposite to the direction in which the skirt extends; and trim which extends around the ring so as to mask it at least in part, the trim having a body defining a top end forming an inwardly-extending rim that extends inwards and then downwards so as to define an inner sleeve. The sleeve comes into engagement with the inside surface of the socket; and the inner sleeve forms a resilient tab which extends outwards and upwards so as to define a free end which comes into contact with an inside surface of the socket.",
  "claims": [
    "1. A fixing device for fixing a dispensing member to the neck of a receptacle, said fixing device comprising: a fixing ring comprising a bottom skirt serving to come into engagement with a neck of the receptacle, member-receiving means for receiving a dispensing member such as a pump or a valve, and a top socket which extends in the direction opposite to the direction in which the skirt extends, said socket defining an outside surface and an inside surface; and trim which extends around the ring so as to mask it at least in part, the trim comprising a body defining a top end forming an inwardly-extending rim that extends inwards and then downwards so as to define a substantially cylindrical inner sleeve, said sleeve coming into engagement with the inside surface of the socket; wherein the inner sleeve forms at least one resilient tab which extends outwards and upwards so as to define a free end which comes into contact with the inside surface of the socket.",
    "2. A device according to claim 1, in which the free end of the resilient tab bites into the socket.",
    "3. A device according to claim 1, in which the socket forms an inwardly-projecting shoulder under which the free end of the tab is received.",
    "4. A device according to claim 1, including at least three resilient tabs distributed circumferentially.",
    "5. A device according to claim 1, in which the tab is formed by a cutout in the sleeve.",
    "6. A device according to claim 1, in which the inwardly-extending rim and the sleeve form an annular recess in which the socket is engaged via its free top end, the body of the trim being spaced apart from the socket at the free top end.",
    "7. A device according to claim 1, in which the free ends of the tabs form rotation-preventing corners preventing the trim from rotating on the fixing ring.",
    "8. A device according to claim 1, in which the socket forms a bevel serving to facilitate engaging the trim on the ring."

  "description_excerpt": "The present invention relates to a fixing device making it possible to fix a dispensing member such as a pump or a valve to the neck of a receptacle. This type of device is in frequent use in the fields of perfumes, cosmetics, or indeed pharmaceuticals, for fixing a pump or a valve to the neck of a receptacle forming a reservoir in which the fluid to be dispensed is stored.\n\nIn general, this type of fixing device comprises a fixing ring and trim which extends around the ring so as to mask it at least in part. The trim has an aesthetic appearance function, but it can also perform a technical function in co-operation with the fixing ring. Usually, the trim is made of metal for reasons purely of aesthetic appearance. However, the trim can also be made of a plastics material. Conventionally, the fixing ring includes a bottom skirt serving to come into engagement with the neck of the receptacle. The bottom skirt can extend inside the neck, but in general it extends around the neck. A variety of techniques are used for fixing the skirt into or onto the neck. For example, when the skirt extends around the neck, it is possible for the neck to form one or more inside snap-fastening profiles serving to come into engagement under a reinforced portion or “lip” formed by the neck. The skirt can be in the form of a continuous cylinder, or else it may have flexible tabs extending side-by-side around the periphery of the skirt. The trim can then serve as locking means for holding the tabs in engagement under the lip.",
