Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sprayer for lotions, perfumes, sanitary products and the like, the operation of which is controlled by a push piece, whether of the propellant gas spray type or the pump spray type. be done. The operation of said type of sprayer is:
It is brought about by the pressure applied to the push piece, possibly by continuous pressure if the atomizer is of the so-called pump type.

In order to prevent the push piece from being accidentally pushed, 198
French patent application S3-:07441 of May 4, 2003 discloses a fixed covering housing surrounding at least the push piece of the atomizer, the covering housing comprising at least one window;
The window exposes a surface of the push piece on which pressure must be applied for propulsion of the push piece by a finger engaged thereto. The said patent application discloses that the said patent application is constructed as a sliding element guided in a covering housing and can be moved over a distance equal to the travel of the pushing piece in front of a window of the covering housing. A push piece is proposed that includes a hole that provides a grip.

This conventional sprayer embodiment offers great protection against accidental manipulation: however, if the sliding element forming the push piece is caught through the window, the possibility of such accidental manipulation is reduced. It still remains.

The aim of the invention is to completely eliminate such a risk by making spraying possible only after at least one activation operation, so that spraying does not occur as a result of spontaneous actuation. Only happens.

U.S. Patent Nos. 3,702.608 and 3.698.
No. 604 also proposes protecting the push piece by a cover housing which is rotatably mounted on the top of the container of the liquid to be sprayed, the cover housing being formed with a window. , the window reveals in one direction a passage to the push piece and likewise a passage for the atomized liquid jet. In U.S. Pat. No. 3,702,668, the sheathing housing is made of two cylindrical sheaths, the inner sheath is fixed to the container, and the outer central sheath is pivotable. Each jacket is provided with diametrically opposed holes that must be aligned to allow spraying. In both of these embodiments, the outer surface of the covering housing is rotated to allow use of the sprayer, and the surface is textured with ridges and ridges to avoid accidental rotation. The latch that prevents rotation of the outer covering must be provided with metal means, which complicates the implementation of the construction. Furthermore, the presence of windows in the outer jacket and the presence of a seal between the outer jacket and the atomizer body are aesthetically detrimental.

According to the invention, the improvement is a covering housing surrounding the pusher piece of the atomizer, comprising at least one window in the covering housing, the window being able to propel the pusher piece by means of a finger engaged thereto. and diametrically opposed windows for the passage of the atomized liquid jet, at least 90°
The pushing piece, which includes a bearing surface having an angular range of The rotation of the pusher piece within the covering housing due to the torque imparted to a portion of the core of the pusher piece visible through is to bring the bearing surface or smooth surface of the pusher piece in front of the window.

According to another feature of the invention, the pusher piece is latched so as not to cause longitudinal propulsion causing operation of the atomizer in other positions than the position of use of the pusher piece. . This configuration prevents longitudinal frictional forces from manipulating the atomizer.

According to another feature, the push piece is prevented from rotating at least in the closed position and preferably in the spraying position by a resilient snap device.

According to another feature, the covering housing is made up of two half housings that fit snugly into each other, thus making access to the container containing the contents possible for refilling or replacing the container. The opening of the sheathing housing (7) brought about is provided by a cam action between a bevel that is fixedly connected to the pusher piece and a bevel that is fixedly connected to one half-housing. This feature prevents children from opening the covering casing and therefore prevents the access of the container by children as well as the pushing piece freed from the covering casing, especially if the rotational force to be applied is sufficiently high. access is prevented. According to an embodiment, the rotary pushing piece includes a pair of interdigitated flange accessible from the window, which flange can be applied with a lateral opening torque to the covering housing by a finger or a tool. give.

Other features of the sprayer according to the invention will become clearer from reading the detailed description of the bathroom sprayer in conjunction with the accompanying drawings.

In the figure, 1 indicates a front half-casing, and 2 indicates a rear half-casing. In horizontal section, the central part 3 bulges out in the arc of a circle in its upper part, while the lateral parts 4 and the lower part 5 correspond to the cross-section of a parallelepiped.

The half-casings 1, 2 each have a window 6 in the center below them, which window 6 allows the volume in the glass container 7 housed between the two half-casings 1.2 to be A flange is formed above said window 6 by a second window 8 which is an access window to the push piece of the atomizer. The two housing halves 1.2 are assembled by fitting the half-thickness separation edges 9 into each other, the gap 10 remaining after assembly avoiding separation by lever action. It has been made as small as possible.

The container 7 corresponds to the shape of the covering housing consisting of the two half-casings 1.2 and has a height such that its upper surface 11 is at the level of the upper edge of the window 6. It is. The center of the core is fixed to the pressure pump 12. If the liquid to be atomized is under pressure in the container, the pressure pump 12 may also be a known pressure valve. In the case of a pump, the pump can be kept in place by screwing its end into a threaded neck that allows filling the container. The push piece 13 forming the pump head has a fitting sleeve for the pump head 14 and a passage which connects to the end of the delivery tube 15 and terminates in a spray nozzle 16 radially directed on the push piece body. -7- includes a cylindrical body provided at its bottom. A longitudinal groove 17 is formed in front of the spray nozzle, which groove 17 cooperates with a joint 18 on the inner surface of the front housing half 1 so that the joint 18 and the groove 17 coincide. The pushing piece 13 is allowed to descend only occasionally.

The joint 18 also engages under the lower edge of the skirt 19 in the other orientation of the push piece 13.

The push-post body is formed with a diametrical hole 20 for engagement of the index finger, the diameter of which is sized to snugly engage the upper part of the cover housing containing the window 8.

The pushing piece 13 is moved by 2 due to the torque applied to its circumferential surface.
Can be rotated between two primary positions. Its primary use position is shown in FIGS. 3 and 5, and its closed position is shown in FIGS. 2 and 6. In the position of use, the holes 20 are aligned with the windows 8 of the two housing halves 1, 2, the spray nozzle 16 faces the front window 8 of the front housing half 1, and the groove 17 faces the joint 18. do. Therefore, the pusher piece 13 is propelled with the index finger engaged in the hole 20, making it possible to spray or jet the liquid. In the closed position (FIG. 6), the hole 20 is located between the two half-casings 1, 2, and the joint 18 engages directly below the scars 1-19 of the push piece 13. In order to maintain the pushing piece 13 in the two positions, the elastic protrusion 21 is pressed against the pump 12.
, the elastic protrusion 21 is formed by two notches 22 . around the inner wall of the skirt 19 of the pushing piece 13 .
23, the positions of the notches 22,23 corresponding to the two main positions.

In order to be able to open the covering housing 1.2, a cam 24 is formed on the inner surface of the part 3 of the rear housing half 2 at the level of the skirt 19 of the push piece 13. In said position, the skirt 19 is cylindrical, covering half of its inner circumference, and is offset above its other half, which half covers the other half of the circumference 25 of the protrusion of the cam 24. It is smaller at the top. In this embodiment, the pushing piece 13 is indicated by the arrow F.
When rotated from the open position (Fig. 5) as shown, skirt 1
9 applies thrust to the cam 24 which disengages the flanges 9 of the half-casings 1 and 2 from each other.
