According to the invention, the cover is equipped with a metering pump (3) which comprises a pump body (4) and a dip tube (5). By elsewhere, said pump (3) advantageously includes a plug (6) integral with the pump body (4) intended to cooperate with the means of fixing (MF) of the cover to be connected to it.

The cover (1) also includes connection means and locking (MC) intended to cooperate with means corresponding and complementary to the pot (2). According to the different embodiments described, the cover (1) is intended to be screwed or clipped to the pot (2). However, it goes without saying that said means of connection and lock could be of different type without for as much to leave the field of protection of the invention.

According to the first embodiment illustrated in Figures 1 to 6, the cover (1) includes a horizontal transverse wall (12) extended externally and downwards (BA) by a peripheral wall external (13). Said horizontal transverse wall is advantageously circular and includes the hole (7) intended to receive the dip tube (5) and / or the pump body (4) of the pump (3). The peripheral wall (13) is provided with connection and locking means (MC) intended for hermetically securing said cover (1) to the container (2). Said connection means (MC) are constituted, according to this mode of execution, by clipping projections (14) regularly arranged on the lower perimeter of said peripheral wall (13), said projections being intended to cooperate with a corresponding flange located peripherally on the opening of the container (2).

According to this first embodiment of the invention allowing to use a standard dosing pump (3) whose plug (6) is threaded, the fixing means (MF) of the plug (6) consist of a cylindrical peripheral wall (8) extending upwards (HA) of peripherally around the hole (7) thereby projecting towards the outside of the container (EXT), said wall (8) comprising a thread external (9) intended to cooperate with the internal thread (10) of the plug of the dosing pump (3), as shown in Figures 2, 3 and 6.

According to a variant not shown of this first mode of embodiment, the cover is intended to allow the use of a pump dosing machine of the type provided with a cap comprising an external thread, the fixing means then being constituted by a peripheral wall cylindrical with additional internal thread. note that said wall can thus project either outwards or towards inside the container.

In addition, said cover (1) can take various forms without however, depart from the scope of the invention. So the hole (7) intended for the passage of the dip tube (5) can be located for example on a hemispherical wall (16), as illustrated in FIG. 7, or be located on a portion of the peripheral wall, as illustrated in FIG. 8. moreover, that the cover (1) may have guide means (MG) of the dip tube (5) for positioning the end lower inlet (5a) of the dip tube (5) substantially at the bottom of the container (2), especially when said tube is advantageously made made of flexible material. In addition, said guide means (MG) can be mainly provided when the hole (7) is not located so as to naturally allow said positioning of the end of said tube substantially at the bottom of the container. Said guide means (MG) can be formed, as for example in the illustrated variants Figures 7 and 8 of a directional ramp (15).

According to a second embodiment illustrated in FIGS. 9 to 12, the cover (1) is of the type described above. It has a hole (7) intended for the passage of the dip tube (5) and / or the body (4) of the pump (3), fixing means (MF) intended to allow the fixing of the plug (6) of said pump and means of connection and locking (MC). In addition, said cover is provided with means adaptation (MA) intended to allow its use over a wide range of different containers.

According to this second embodiment, said means as shown in Figure 9, by an succession of external peripheral walls (13a, 13b, 13c) extending downwards (BA) the horizontal transverse wall (12), said walls peripherals being of different diameters, and gradually staging downward by increasing in diameter.

In addition, as shown in Figures 10 and 12, each wall external device (13, 13a, 13b, 13c) includes means for connection and locking (MC) intended to cooperate with means corresponding and complementary to the different pots on which the cover is intended to fit.

Thus, the succession of external peripheral walls (13a, 13b, 13c) of different diameters and progressively more and more large allows the lid to be used on pots different diameters, as shown in Figures 10a, 10b, 10c; the container opening diameters D1, D2, D3, corresponding advantageously to the diameters of the external peripheral walls on which locks the pot. According to this second mode of embodiment, the connection and locking means (MC) are also constituted by clipping projections (14), however said connection ways could be obtained by other types of devices such as screwing without leaving the field of protection of the invention.

According to a possible variant not shown, said means adaptation could consist of rings of diameter different intended to be removably attached to a wall external device of the cover or on its horizontal wall, said rings being provided with connection and locking means allowing the lid to be connected to the container, the opening of which is corresponding diameter. According to another variant not shown, the adaptation means may consist of walls external devices extending downwards, decreasing in diameter, said walls being slightly inclined relative to the vertical of so as to allow said cover to fit into the opening of the container.

It goes without saying that the cover can also, according to this second mode of realization, cover various forms like those illustrated in the variants of the first embodiment (Figures 8 and 9).

Of course, it is possible to provide a plug (11) intended to close the hole (7) when the cover (1) is not equipped with a pump dispenser (3), as shown in Figure 13.

FIG. 14 illustrates an improvement according to which it is provided a cap (30) intended to close the end (31) of the nozzle of the pump dispenser, said cap being able to be connected to said spout as according to illustration or be independent and removable or be advantageously secured to the cover.

Figures 15 and 16 illustrate an alternative embodiment according to which the connection and locking means and the means adapters consist of fixing lugs (32) distributed over the internal perimeter of the external peripheral wall (13) of the cover. Said fixing lugs are advantageously bevelled at their upper end so as to advantageously allow the adaptation of the cover by screwing and unscrewing, they are more made of flexible and elastic material so as to allow adapting said cover to pots of different standard diameters. In addition, the peripheral wall may be provided with recesses (33) to allow the mounting tabs to be easily removed especially when the lid is used on pots whose diameter is adjusted to the diameter of the outer peripheral wall.

Of course, the invention is not limited to the modes of realization described and represented as examples, but it includes also all technical equivalents and their combinations.
