[0022] For the description of the invention and the understanding of the claims, the vertical, longitudinal and transverse orientations according to the reference V, L, T indicated in the figures, the longitudinal L and transverse T axes of which extend in a horizontal plane, will be adopted without limitation.

[0023] In the following description, identical, similar or analogous elements will be designated by the same reference numbers.

[0024] Figures 1, 3 and 9 show the upper end portion 10 of a bottle which is of generally axial tubular shape with axis Al (oriented in the figures in the vertical orientation and corresponding to the vertical orientation of the bottle resting by its base on a horizontal plane) of substantially constant section with external diameter Dext and internal diameter Dint.

[0025] This upper part 10 comprises an upper neck 12 which is delimited axially downwards by a radially external ring 18 and upwards by a free end upper edge 20.

[0026] The radially outer ring 18 has an annular shoulder 22 oriented axially downwards.

[0027] By way of non-limiting example, the upper neck 12 here comprises an intermediate radially external ring 26.

[0028] Below the radially outer ring 18, the upper part 10 of the bottle extends axially downwards by a lower axial section 24.

[0029] The upper neck 12 is here equipped with a closing cap 14 which is arranged axially above the radially outer ring 18.

[0030] In a known manner, and as illustrated in document EP3305680B1, the closing cap 14 comprises two articulated parts including a lower part or base 30 and an upper part 32 forming a cap or cover and which can be removed and replaced several times to pour all or part of the contents of the bottle.

[0031] The lower part 30 is here in the form of a ring which is arranged above the radially outer ring 18 and which is retained on the upper neck 12 by the intermediate radially outer ring 26.

[0032] The upper part 32 of the closing cap 14 comprises a ring 34 which, in the closed position, is superimposed on the lower part 30 to which it is connected by a thinned articulation 36 to be able to pivot around a transverse axis A2.

[0033] As can be seen in [Fig.2], to ensure the attachment of the upper part 32 to the lower part 30 of the closing cap 14, a flap 36 is provided with a notch which cooperates with the outer intermediate ring 26 in the closed position.

[0034] The upper part 32 comprises a flat upper plate 40 which, at its periphery, is extended by an external radial collar 42.

[0035] The safety cap 50 according to the invention, which is illustrated in particular in the figures, will now be described, in cooperation with the upper end part 10 of the bottle and with the closing cap 14.

[0036] The function of the safety cap 50, when secured to the bottle as shown in Figures 10 and 11, is to prevent any inadvertent or accidental opening of the closure cap 14.

[0037] For this purpose, the safety cap 50 comprises an internal housing 52 which is capable of receiving the upper end portion 10 of the bottle with the radially outer ring 18 above which the closing cap 14 is arranged in the closed position.

[0038] The closure cap 14 is kept in the closed position by housing the stack constituted by the radially outer ring 18 and by the closed closure cap 14 between two opposite wall elements, respectively a lower wall element 56 and an upper wall element 58 belonging to the safety cap 50.

[0039] This principle of retaining the closing cap by a safety cap according to the invention is applicable whatever the design of the closing cap arranged above a radially external ring 18, the latter being an element which is found present in an almost general manner, whatever the design and type of the bottle.

[0040] In particular, whatever the design of the means for retaining the lower part of the closure cap on the upper neck, above the radially outer ring 18, the principle of implementing a safety cap according to the invention consists of making the lower wall element 56 cooperate with the radially outer ring 18, and nota.

[0041] In particular with its annular shoulder 22 oriented downwards which appears in the form of an available clear surface.

[0042] The principle is also applicable when the lower part of the closing cap is mounted screwed onto the upper neck above the radially outer ring 18, as well as when the lower part is retained by fitting between the two radially outer rings 18 and 26 and when the upper part opens and closes by screwing onto the upper neck while remaining connected, or not, to the lower part when it is in the open position.

[0043] In the embodiment illustrated in the figures, the body 54 of the safety cap 50 comprises at its lower part a semi-annular stirrup 60 whose semi-annular transverse upper wall 56 here constitutes the lower wall element which axially delimits the housing 52 downwards.

[0044] Each free end 62 of the semi-annular stirrup 60 is extended by an arm 64 of greater width in such a way that, as can be seen in [Fig.7], the distance D2 separating the opposite internal faces 66 facing each other of the two arms 64 is less than the internal diameter DI of the semi-annular stirrup 60. The internal diameter DI is substantially equal to the external diameter Dext of the upper neck 12.

[0045] Thus, the two arms 64, which are elastically deformable, constitute a radial insertion inlet of the lower section 24 of the upper neck 12 into the stirrup 60.

[0046] Crossing the arms 64 constitutes a step called elastically tight mounting of the safety cap 50 on the upper neck 12.

[0047] In this same embodiment, the body 54 comprises an upper bottom plate 68 here in the form of a half-disc which is delimited downwards by an internal wall 58 which constitutes the upper wall element which vertically delimits the housing 52 upwards.

[0048] Beyond its diameter limit 72, the upper bottom plate 68 is extended by a thicker end portion 74 whose internal wall 76 is inclined downwards to constitute an insertion ramp.

[0049] To receive the peripheral collar 42 of the upper part 32 of the plug of closure 14, the body 54 here comprises a radially internal semi-annular groove 80 which extends the plane of the internal wall 58.

[0050] To facilitate the guiding and introduction of the peripheral collar 42 into the inner radial groove 80, and of the plate 40 under the plate 68, at each of its two ends, the semi-annular inner radial groove 80 is extended by a section of guide grooves 84.

[0051] As a complement, and as can be seen in particular in figures 4, 5 and 11, at its upper part, the safety cap 50 comprises a flange 90 which is made in a single piece with the body 54 in the form of a half-ring which allows its user to avoid losing the safety cap 50 when he is not using it and to have it easily available.

[0052] Indeed, the flange 90 allows a lace or a strap, or a shackle to be passed through it so as to connect the safety cap 50 for example to a container such as a bag.

[0053] By way of non-limiting example, the safety cap 50 is made in a single piece with its one-piece body 54 made by molding in plastic material.

[0054] The mounting of the safety cap 50 in the safety position on the upper part of a bottle whose upper neck 10 is equipped with a closing cap 14 in the closed position is illustrated with reference to FIGS. 9 to 11.

[0055] As can be seen in figure nine, the safety cap 50 is put in place by positioning it laterally relative to the closing cap 14 and, initially, by introducing the lower section 24 of the upper neck 12 between the arms 64 and by positioning the peripheral collar 42 of the upper part 32 of the closing cap 14 in the guide grooves 84.

[0056] Considering [Fig.9], the assembly continues by fitting the closing cap 54 by elastic deformation, moving the latter from right to left in such a way that, on the one hand, the lower section 24 comes to be housed inside the stirrup 60 and in such a way that the upper plate 40, after having run along the ramp 76, comes to be housed under the internal wall 58 of the upper bottom plate 68 with the corresponding portion of the peripheral collar 42 received in the internal radial groove 80.

[0057] The assembly thus produced is an elastically tightened assembly which ensures that the safety cap 50 is kept in place in its functional position.

[0058] The elastic clamping or elastic interlocking effect is achieved in different functional areas, some of which have been described previously.

[0059] The dimensions of the safety cap 50 and in particular of its housing 52 with the various functional parts of the latter are such that its fixing in the functional position is ensured by elastic clamping of the upper neck 12 with its radially outer ring 18 axially and / or radially.

[0060] To use the bottle again by opening the latter, it is sufficient to extract the safety cap 50 by acting again by elastic deformation in order to be able to freely access the closing cap 14 again.

[0061] The safety cap according to the invention can be marketed or distributed for promotional purposes, for example with a batch of bottles.
