Abstract

1. Spray device for an aerosol product in which the nozzle (23) is spaced from the container by being mounted at a first end of an elongate tip (21) the other end of which is connected to a push-button (22) the actuation of which controls the opening of a valve (2) through the said push-button, the tip being constituted by a flexible extruded tube (21) and a semi-rigid plastically deformable thread-like element (33), characterized in that the thread-like element (33) is incorporated in the wall of the tube (21) during the extrusion of the said tube.

Description

The present invention relates to a product diffuser device

  aerosol in which the diffuser member,

  or nozzle is removed from the container, can or bottle. The

  is mounted at a first end of a tube-shaped tip whose second end is connected to the

  outlet of the can, on a pusher, whose actuation com-

  request the release of a valve.

  There are two types of such diffusers: a) the tip is rigid and has no possibility of orientation relative to the pusher, itself fitted on the valve controlling the mechanism; b) the tip is adjustable, it has one or more

  degrees of freedom from the pusher.

  It is this second type that concerns the present invention. The advantages of this arrangement, compared to the rigid tip are: - less space, after folding the tip, both for the conditioner, for the user; - operational safety in the folded position, the connection being cut, and the folded endpiece coming into

  besides blocking the operation of the pusher.

  However, the development of these last few bits remains limited because users complain about

  the poor sealing of the device.

  Indeed, the swivel tips have an articulated joint that gives rise to leaks. This is in

  effect of a cheap piece that is part of a packaging

  lost, made of molded plastic.

  The manufacturing conditions do not allow any

  machining and absolute sealing can not be ensured.

  The present invention makes an important contribution

  to this technique by providing an ori-

  table with absolute watertightness in all

  sions. According to the present invention, there is provided an aerosol dispenser device in which the

  nozzle is removed from the container by being mounted at a first

  first end of an elongate tip whose other end is connected to a pusher whose actuation controls the triggering of a valve through said pusher. It comprises a flexible tube whose one end is sealingly connected to the outlet of the valve in the pusher, and whose other end is connected to the nozzle, associated with deformable rigid means for maintaining the

  flexible tube in at least two different orientations.

  In another embodiment, the device

  has an elongated rigid element, a first end

  mity is connected to the pusher by a mechanical connection such as a hinge or a ball joint and on the second

  end at which is fixed the nozzle.

  In another embodiment, the tube is associated with a semi-rigid element, plastically deformable, 3. placed in the tube or surrounding the tube, for example made of metal

such as stainless steel.

  Other features of the invention appear

  will be discussed in the description that follows, given in

  As a non-limiting example, with reference to the accompanying drawings, which will make it clear how the invention can be realized. In the drawings: FIG. 1 is a sectional view of embodiment of the invention, of a mouthpiece

In the embodiment of the

a first mode

diffuser in

  of the nozzle of the other mode along the line in Figure 4 for Figure 3 Figures 1 and 2, over a large part of its length, the tip has the shape of a gutter, which can for example, to widen from the free end to the articulated end 10b. The free end 10a has an end opening 12 in which can be housed a nozzle. For some products, the opening can itself form the nozzle. This opening 12-communicates

  with a channel 13 in which is engaged the first

  mity of a tube 14, whose second end is connected,

  in the pusher 11 at the outlet of a valve well 15.

  The gutter shape of the tip allows to place the tube

easily to assembly.

  As we know, the depression of the pusher 11 pro-

  the opening of a valve, not shown, and the flow of fluid under pressure in the valve well. From there, the fluid, which may be a liquid or a mixture of liquid and dissolved gas in the course of disengagement, is passed through the tube 14 to the opening 12 where it is atomized, either by the shape and the size of this opening 12,

  either by the action of a separate jet.

  In the position shown in Figure 1, the tip 10 is perpendicular to the valve well 15 of the

  pusher, that is to say perpendicular to the axis of the recess

  on which is mounted the pusher 11. The jet is

  then spaced as far as possible from the container.

  The articulation of the tip can be achieved simply by two small pins 16 placed on the sides of the end 10Ob of the tip, and engaged in holes

  corresponding pusher. Figure 2 shows the bottom end

  abut 90 down. We see that at the end 10b of the tip is formed a step 17, which in the folded position

  (Figure 2) comes on a rebord 18 with a cap 19. This

  fishing the depression of the pusher. It is a security

  singing the maneuver and ejection of the product when the tip is folded. The enlarged end 10b of the tip, articulated

  on the pusher has a cylindrical portion 10c,

  putting during tilting of the mouthpiece, to stay at

  vicinity of a wing 11a of the pusher. This improves the

  thetic and prevents the entry of dust and other foreign bodies. This cylindrical portion 10c has a slot d for the passage of the tube 14 when the tip is raised, in the working position (Figure 1). The end 10b can be reinforced by ribs 19. Such an arrangement allows

  the deflection of the tip on an angle of 90 in a plane.

  Instead of a hinge, we can provide a kneecap if we

  the desire. In all cases, the fluid passes on

  these whose watertightness is perfectly controlled, and there

has no flight.

  Figures 3 and 4 show an alternative embodiment of the invention. A flexible plastic tube 21 is connected at one end to a pusher 22 of an aerosol valve and at its other end carries a nozzle 23. In the tube 21 is placed a rigid or semi-rigid body 25 plastically deformable, such as annealed stainless steel wire. By a rigid or semi-rigid body, we mean

  a body of rigidity significantly greater than that of the tube.

  In the context of this invention, a plastic deformation is such that the force exerted on this body gives it a stress located in the plastic zone of the chosen material

  (Hooke's law) sufficient to overcome the natural effort

  elastically flexible tube. Under these conditions, the tube 21 takes the form of the wire 25, which can be brought to

any desired shape.

  FIG. 5 is a variant section of a tube 31, which comprises a large channel 32 for the passage of the fluid, and a small channel housing the wire 3. This wire can

be extruded with the tube.

  In FIG. 6, the tube 41 is sheathed over part of its length by a tube 42, for example aluminum, which can be plastically deformed to communicate with the

tube 41 the desired orientation.
