Claims (6)

1. Skin cream applicator-dispenser, for tube or bottle comprising a ring, provided with a protective cover (12), characterized in that it comprises an applicator cap (6) comprising a domed upper part with a smooth exterior, a sealing skirt (7) fitting inside the ring (2) of the tube or bottle, a hooking skirt (8) being fixed on the ring (2), an outlet orifice (16) of the contents of the tube or bottle (1), an outer skirt (10), in that the attachment skirt (8) is reinforced by stiffening fins (11) and in that the protective cover ( 12) comprises a central sealing pin (13) closing off the orifice (16) of the applicator cap (6). 2. Skin cream applicator-dispenser according to claim 1, characterized in that the hooking skirt (8) is fixed on the ring (2) of the tube or bottle (1) by means of a rod bottom (15) engaged in a groove (4) of the tube or bottle. 3. Skin cream applicator-dispenser according to claim 1, characterized in that it comprises an anti-rotation device consisting of fins (9) integral with the inner surface of the domed part of the applicator cap (6) and of the attachment skirt (8), fins which are inserted into the outer grooves (3) of the ring (2) of the tube or bottle (1). 4. Skin cream applicator-dispenser according to claim 1, characterized in that the protective cover (12) comprises at the upper part an air exhaust hole (18) facilitating the mounting of said protective cover on the applicator cap (6). DESCRIPTION In perfumery, various products in the form of cream, such as care creams, make-up remover creams, sunscreens, washing creams, are packaged in plastic or metallo-plastic tubes with a screw ring. Body milks are packaged in flexible polyethylene screw-neck bottles. The shapes and volumes of the caps are different depending on the desired presentations. To use the product, it is placed in the palm of the hand and then applied to the face or body. To allow a direct and pleasant application of the product on the skin, the present invention proposes to create a cream applicator-dispenser. From a technical point of view, three essential criteria are met: — an external shape of the cap which allows a pleasant contact for a direct application on the skin, — the inviolability of the applicator cap on the tube, — the guarantee of tightness of the applicator cap to the product. The above results are achieved in accordance with claim 1. The following description, given with reference to the appended drawings given by way of non-limiting example, will make it possible to better understand the characteristics of the invention. In these drawings: Figure 1 shows in elevation and in half-section an applica-tor-distributor according to the invention. Figure 2 is a partial horizontal sectional magnification of the assembly of the applicator-dispenser on the tube ring. The flexible tube or bottle 1 with ring 2 has grooves 3 in the upper part, the lower part comprising a groove 4 itself connected to the grooves 3 by a ramp 5. The applicator cap 6, preferably made of polypropylene, has a domed upper part for gentle application and an ogival side part to allow easy fitting and removal of the protective cover 12. The applicator cap 6 has three skirts: — a sealing skirt 7 applied to the inner wall of the ring 2 of the tube or bottle 1, —■ a hooking skirt 8 on the tube or bottle 1 by means of a rod 15 which is inserted into the groove 4, — an outer skirt 10 on which the protective cover 12 is fixed. The attachment skirt 8 carries anti-rotation fins 9 which engage, after assembly, in the grooves 3 of the ring 2. Several, for example four, stiffening fins 11 are formed between the outer skirt 10 and the attachment skirt 8 to reinforce the structure of the applicator cap. The protective cover 12, preferably made of crystal polystyrene or polypropylene, has a central sealing stud 13 which, when the cover is fixed on the applicator cap 6, closes off the outlet orifice 16 thereof. On the outer skirt 17 of the protective cover 12 are formed, at the bottom and inside said outer skirt, sectors of hooking rods 14, for example four in number, which engage in a corresponding groove 19 of the outer skirt 10 of the applicator cap 6. At the upper part of the protective cover 12 is formed an air exhaust hole 18 facilitating the mounting of the cover 12 on the applicator cap 6. The applicator cap 6 and the protective cover 12 are delivered assembled to the tube manufacturer 1 who can mount them in a single operation on the ring 2. This assembly method appeared essential so that the packaging of the tubes is done on specific machines. The tubes being positioned upside down, the product is introduced through the bottom of the tube which is then welded. In the case of flexible bottles, the applicator caps and protective caps are delivered separately and assembled by the packager. The invention is not limited to the embodiment shown and described, but modifications can be made without departing from it. 2 5 10 15 20 25 30 35 40 45 50 R 1 drawing sheet
