DETAILED DESCRIPTION OF THE INVENTION

(9) According to the aforementioned figures, the present invention, i.e., “DISPENSING DEVICE FOR PRESSURIZED FLUIDS WITH AN ANTI-ACTUATION SYSTEM”, comprises a cover (T) that has a body (1) connected to an actuation button (2), wherein said actuation button (2) has a spray channel (3) and an anti-actuation system (4) that prevents the actuation button (2) from moving coaxially to an actuation valve (VA) stem.

(10) The body (1) is the outer part of the lid (T), which has a thin wall and a base (11) essentially cylindrical with an open bottom and which tapers toward the top that is closed.

(11) In an embodiment of the present invention, the base (11) connects to a concave radius (13), forming an edge (12) at the junction of the two parts. The curvature of the concave radius (13) decreases until it reaches the inflection point where the convex radius (14) starts. Said convex radius (14) increases the curvature to the flat top (15), where said flat top (15) forms the body (1) cover.

(12) The base (11) has fixation means on its inner side, where said fixation means hold the body (1) in a pressurized vessel (VP), such as an aerosol or congener spray, either directly in the vessel or in the actuation valve (VA). In an embodiment of the present invention, the fixation means is made up of a rib (5) of semicircular profile that runs through the circumference of the inner wall and a limiter ring (6), that limits the portion of the pressurized vessel (VP) that enters the body (1) of said cover (T).

(13) The top of the body (1) has a gap where the actuation button (2) is housed, in the inner part of the gap there is a guide wall (16) that prevents any lateral displacements of the actuation button (2) and protects the inside of the body (1).

(14) Said actuation button (2) is located below the top of the body (1), so that it is protected from accidental shocks or activation. Said actuation button (2) is connected to the body (1) by a flexible region (7) that imparts to the actuation button (2) a pivoting movement and allows coaxial movement to the stem of the actuation valve (VA), so that pressing the actuation button (2) causes the release of fluid from inside the pressurized vessel (VP).

(15) In an embodiment of the present invention, the actuation button (2) forms a flat, essentially rectangular and of inclined surface, forming a ramp that converges towards the top of the body (1). Alternatively in this embodiment, a rib (21) can be used at the lower edge of the actuation button (2) in order to give greater structural rigidity to said actuation button (2).

(16) In a possible embodiment of the present invention, the body (1) has in its front portion a chamfer (17), which is an angled cutout, essentially flat, where the gap (9) through which the spray channel passes is located.

(17) At the bottom of the actuation button (2) is the valve stem fitting (8), which is where the actuation valve stem (VA) engages, and said valve stem fitting (8) is connected to the spray channel (3).

(18) In an embodiment of the present invention, the valve stem fitting (8) and the spray channel (3) are arranged at an angle between 90° and 180°, with the spray channel (3) facing the front of the cover (T), and there may be a gap (9) in the front portion of the body (1), where the end of said spray channel (3) is located.

(19) In an embodiment of the present invention, the end of the spray channel (3) can receive another element in its outlet, in a fixed or removable way, such as a duct, flexible or rigid, to assist in the deposition of material in places of difficult access, for example.

(20) Additionally, the spray channel (3) may be able to receive a rupture insert, mechanical or non-mechanical.

(21) The spray channel (3) can have more than one outlet, allowing a dispersion in different directions or with a larger dispersion area.

(22) The anti-actuation system (4) prevents the actuation button (2) from moving, thereby preventing the actuation valve stem (VA) from being pressed, consequently preventing the release of fluid from the pressurized vessel (VP).

(23) In an embodiment of the present invention, the anti-actuation system (4) is composed of a locking element (41) that has an articulation (43), which allows said locking element (41) to perform a pivot movement toward the spray channel (3). In the closed position, the locking element (41) prevents the movement of the spray channel (3), thus preventing the movement of the actuation button (2), as shown in FIG. 1. In this embodiment, it is preferable that there is a reinforcement (31) next to the spray channel (3) for improved rigidity, as a way to prevent said spray channel (3) from being flexed. When rotating the locking element (41) to the open position, the spray channel (3) is released, previously anchored/supported, thus allowing the activation of the actuation button (2). In FIG. 2, one can see the locking element (41) moving to the open position, rotating on the “AA” axis. FIG. 6 shows a complete illustration of the movement of the locking element (41).

(24) The articulation (43) can be positioned above or below the spray channel (3). Alternatively, the articulation (43) can have a spring effect, which maintains the locking element (41) in the open or closed position. Additionally, means to secure and hold the locking element (41) can be used in the open or closed position. In an embodiment of the present invention, there is a fixing recess (46) that accommodates the locking element (41) when in the open position and maintains said locking element (41) in position through protrusions (42) in the form of ribs or embossed dots on the body (1).

(25) The anti-actuation system (4) may contain a locking element (41) with a hollow region (44) for accommodation of the spray channel (3), so when the locking element (41) is in the closed position, said hollow region (44) accommodates the spray channel (3), preventing the spray channel from moving. Said hollow region (44) can have the geometry of the spray channel (3). Additionally, in this embodiment, the locking element can contain a recess (45), which forms a wall, in the same direction as the movement of the actuation valve stem (VA), for better accommodation of the spray channel (3), in the hollow region (44).

(26) In another embodiment of the present invention, said locking element (41) may be a non-hollow housing where the spray channel (3) accommodates when the locking element (41) is in the closed position. Said housing can have the shape of the spray channel (3), of a circle, of a square, or another shape that allows said spray channel (3) to be accommodated inside when the locking element (41) is in the closed position, preventing the actuation button (2) from moving.

(27) In still another embodiment of the present invention, there is anti-actuation system (4) where the locking element (41) has in its inner part ribs that, when said locking element (41) is in the closed position, prevent the actuation button (2) from moving.

(28) To facilitate the opening of the locking element (41), an opening recess (18), located on the body (1), can be used so as to make the start of the locking element (41) movement to the open position easier. Another way to facilitate the opening is to use a tab in the locking element (41), so that it is possible for the user to position his/her finger on said tab to move the locking element.

(29) Additionally, the locking element (41) can be built in the closed position, with breaking points in the form of a seal that breaks at the first opening of the locking element (41). In this embodiment, the breaking points can be around the locking element (41) or in the housing of the spray channel (3).

(30) One can also have as a sealing element breaking points between the body (1) and the actuation button (2), which break with the first activation of said actuation button (2).

(31) The main advantage of this invention is that it offers a spraying device for pressurized vessels (VP), such as aerosols, which is functional and manufactured as a single piece, thus facilitating the production and assembly process in the pressurized vessel (VP), in addition to presenting an effective, simple, and easy-to-handle anti-actuation system, which prevents or hinders accidental or improper activation in the open or closed position and can also perform the sealing function.

(32) It should be understood that this description does not limit the application to the details described herein and that the invention is capable of other modalities, as well as to be practiced or executed in a variety of ways within the scope of the claims. Although specific terms have been used, such terms should be interpreted in a generic and descriptive sense, and not for the purpose of limitation.
