    Detailed description of embodiments of the invention
    The invention relates to a safety cover for an aerosol can 100 of known type such as for example shown in FIG. 1.
    The housing 100 is a cylindrical housing comprising an axial valve 101 in a cup crimped at the top of a dome 103 itself crimped on the body of the housing 100. The valve comprises a product outlet tube 102.
    On the housing is fixed the safety cover 1 itself shaped like a dome. The cover snaps onto the setting 110 between the housing and the dome and / or onto the setting 105 between the cup and the dome as will be seen below.
    The cover 1 is provided at its top with an axial opening 3 for access to an axial diffuser device 4 which is mounted on the outlet tube 102 of the valve 101 in the extension of an axis of revolution of the housing and which allows
    leaving theAccording to 1 spray East provided an opening invention, the hood lateral 2 closed or open at way of a part 5, maneuverable between a position masking of Opening lateral and a position of free access at Opening lateral.According to; Figure 2, the opening given 1 access to a
    pusher 6 for operating the valve 101 of the housing through the axial diffuser 4 comprising a tube conventionally receiving the outlet tube of the valve, the operation of the pusher making it possible to push the tube of the valve to open it.
    Still according to FIG. 2, the cover comprises a base 20 provided with a crown 21 forming a lower part of the dome and a cover 30 which is mounted on the base 20 in extension of the crown.
    The cover forms an upper part of the dome and has the axial opening 3 opposite the outlet of the diffuser 4 and which allows the outlet of the product to be sprayed.
    The axial opening 3 in the cover is a circular opening, the edge of which extends towards the inside of the cover by an annular wall 32.
    The side opening is for its part according to the example comprises an upper part 2a in the cover and a lower part 2b in the crown and the flap 5 is slidably mounted in slides 22a, 22b. As shown in particular in FIGS. 2 and 4 of the exemplary embodiment, a first so-called lower slide 22a is produced in the base by a gutter running along the internal edge of the crown. The second so-called upper slide 22b is produced between a rim of the opening in the cover and a bead internal to the cover 220b and shown in FIG. 3.
    The shutter 5 slides inside the cover 1 and moves in rotation around the axis of revolution of the housing, the slides extending well beyond the opening to accompany the shutter 5 over its entire travel.
    According to the example of FIG. 4, to define two extreme stable positions for retaining the shutter, completely closed shutter and completely erased shutter to leave the opening free, the ends of the lower slide 22a and of the shutter are provided with a device latching 51, 52. This device comprises spring hooks 51 at the lower hood corners and stops 52 for latching the hooks at the end of the slide 22a.
    This system ensures that the cover is retained sufficiently so that it does not move when the housing is manipulated, but reduced enough to allow the cover to be maneuvered with a finger. In addition, the spring hooks and the snap-in stops make it possible to have a sensitive feedback when the cover is snapped in and out.
    in an alternative embodiment, the latching device can be produced at the level of the cover.
    Referring to Figures 2 and 4, the base is provided with the axial diffuser device 4 and a central portion forming a wall 23 of semi-circular section around the axial diffuser device.
    The wall 23 is connected to the crown 21 by at least one beam 25. According to the example shown, the beam 25 comprises a platform and ribs 251, 252 reinforcing it.
    The axial diffuser device 4 is for its part secured to a semi-circular plate 4a which extends radially over about a quarter of its periphery by the pusher 6.
    The axial diffuser device is connected, via the plate 4a to the central part by one or more flexible links 24 forming a spring.
    Thus, the wall 23 partially surrounds the axial diffuser and protects the interior of the cover from product splashes and the crown 21 surrounds and protects the diffuser and actuator push assembly on its periphery.
    On the underside of the cover, with reference to FIG. 3, the semi-circular central part extends towards the housing by a skirt 23a provided with lugs 27 for fixing the base on a crimp 105 around the valve of the housing and shown in Figure 1. This allows to securely hang the cover on the housing closer to the valve.
    Complementarily or alternatively, the crown has an internal rim 210 for latching with a peripheral crimp (110) of the housing.
    In addition to fixing the cover, the fact that the crown covers the top of the case at the level of its dome / case body crimping prevents the crown from being pushed inwards and prevents the cover from being raised.
    Back towards the top of the cover, the cover 30 as seen previously comprises an annular wall 32 forming a chimney ending at the top of the cover by the axial opening 3 and visible in particular in FIG. 3.
    A lower part of this annular wall 32 joins the semi-circular wall 23 around the diffuser device 4 and shown in FIG. 2 so as to form an anti-splash channel.
    The lower end of the annular wall 32 surrounds the semi-circular wall 23, the annular wall and the semi-circular wall 23 comprising mutual hooking means 28, 33 adapted to secure the base and the cover.
    According to the example, the hooking means 33 of the annular wall are constituted by an annular flange while the hooking means on the semi-circular wall 23 are constituted by lugs with ramps 28 distributed around the periphery of the semi-circular wall allowing an easy snap-on of the cover on the base and an effective retention of this cover on the base.
    To complete the fixing of the cover to the base, the upper edge of the crown and the lower edge of the cover are also provided with mutual latching means 29, 34 adapted to secure the base and the cover. These means in the form of tongue grooves arranged on the upper edge of the crown 21 and the lower edge of the cover can be completed by bonding or ultrasonic bonding of the cover and the base.
    The cover of the invention which is not limited to the example shown, the lateral opening being able in particular to be made entirely in the cover by reducing the height of the crown and by increasing the height of the wall of the cover or on the contrary entirely in the base is easy to manufacture, robust, allows the hood to be personalized by a choice of different colors between the various parts and makes it possible to protect the fingers of the user from any projection of product and in particular of paint in the case of '' an aerosol can of spray paint.
