Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spray device for perfumes, lotions and other similar products. The spray device includes a watertightly closed reservoir housing a metering pump that communicates with the reservoir at one end and communicates at the other end with a spray nozzle provided in a movable pushbutton at the top of the reservoir; The push button constitutes a means for actuating a metering pump which atomizes a metered amount of the liquid contained in the reservoir. Conventional devices of this type are usually made of glass. The device comprises a storage body made of steel and having a large cross section, the upper part of which is provided with a neck, into which a metering pump immersed in the storage body is fastened, in particular by snapping or screwing.

Due to this configuration, although there is a demand for a handbag (portable) spray device, it is not possible to manufacture a spray device with very small dimensions, especially small dimensions in the thickness direction.

SUMMARY OF THE INVENTION An object of the present invention is to provide a spray device that can be used as is or loaded into an outer case and that has extremely small dimensions, particularly small dimensions in the thickness direction.

In the device according to the invention, the storage body has a flat tubular shape;
Its lower end is occluded by an associated bottom and has engagement means operative to cooperate with engagement means provided on said dosing pump in order to secure the dosing pump introduced through the lower end of the reservoir. and an inwardly projecting annular flange near the top of the reservoir.

In a preferred embodiment, the annular flange projects from the wall of the reservoir with a passage opening parallel to the bottom wall of the reservoir and leading to the end of the metering pump adapted to be actuated by an operating pushbutton. It is configured. Advantageously, the engagement means cooperating on the annular flange and the dosing pump have on the one hand an annular edge projecting from the inner wall of the flange and on the other hand rock a stepped section corresponding to the change in the external shape of the dosing pump. .

According to a preferred embodiment, the bottom of the reservoir is advantageously provided with a filling opening that can be closed by a plug.

It is advantageous if the device according to the invention is made of plastic material and is a possible spare on a used bridge.

Since the metering pump is attached from the lower end of the reservoir and is fixed within the reservoir, the invention makes it possible to create devices with extremely flat cross-sections, with a thickness of less than about 10 aon, which was not previously possible. can.

For a more complete understanding of the invention, reference should be made to the accompanying drawings, which illustrate, by way of example, embodiments of the invention.

The illustrated device in spare form for handbag spray comprises a reservoir 1 made of plastic material in one piece and having a collar 2 on top. A movable push button 3 with a spray nozzle 4 can be slid vertically inside the collar 2.

As shown, the reservoir 1 and the pushbutton 3 have a flat tubular cross section.

The storage body 1 has a base 5 fixed to its lower part by suitable means, in particular by ultrasonic welding. This bottom B5 is provided with a central opening 6 which can be closed by a stopper 7.

Positioned within the reservoir 1 is a metering pump mechanism, generally indicated at 8, which pump mechanism communicates at its lower part with the closed area constituted by the reservoir 1 and whose upper part connects to the movable pushbutton 3. It communicates with the provided spray nozzle 4.

According to the invention, the metering pump 8 is introduced into the reservoir 1 by the lower open end and, after being fixed inside the reservoir 1, the bottom part 5 is attached.

For this purpose, the reservoir 1 has an annular flange 9 projecting inwardly from a wall (not shown) approximately below the collar 2 and parallel to the bottom wall 5.

In order to hook the metering pump 8 to the annular flange 9, the inner wall of the flange 9 is provided with an annular edge 10, which is provided with a stepped support surface 11 corresponding to the external shape of the metering pump 8. It engages the metering pump 8 by means of a ratchet mechanism.

After the metering pump 8 has been introduced into the reservoir 1 and fixed therein by means of a ratchet mechanism, the bottom 5 is attached and the reservoir 1 is filled through the opening 6 provided in its bottom, and the stopper 7 The bottom is closed by.

Although the invention has been described in connection with specific embodiments, the invention is not limited thereto, and it is understood that many changes and modifications may be made without departing from the scope and spirit of the invention. It's obvious.
