Abstract

A device for dispensing a liquid product, comprising a bottle (10) for liquid product having a sprayer (11) that can be separated and refilled, provided with a spray pump with or without air intake, comprising walls (13) that are flexible, in order to move towards each other under finger pressure or following the creation of negative pressure inside the sprayer, and that are resilient, for a return movement after the finger pressure has been released or when said negative pressure becomes zero, such that the vacuum created by the compressing of the walls (13) or by the negative pressure results in the liquid product being sucked from the bottle (10) into the sprayer (11), and the compressing of said walls (13) in turn producing pressure to discharge the liquid product from the sprayer (11) back into the bottle (10).

Description

DEVICE FOR DISPENSING A LIQUID PRODUCT

Domaine techniqueTechnical area

The present invention relates to a device for dispensing a toilet product or an industrial product in liquid form, in particular of the type comprising a bottle or a bottle having a separable and rechargeable sprayer.

Technique antérieurePrior art

A device of the type mentioned, for example, by the published patent application GB-A-2 485 196 is known. This prior device comprises a container containing a liquid product, particularly a perfume, under pressure, and having a disconnectable segment. and which is arranged to be connected to the container so that the contents of the container can automatically pass into the segment through a fill valve, to reload the segment. The rechargeable segment also provides the sprayer for spraying the liquid product.

With the device described in this patent, the container in use having an internal pressure greater than the segment, and said segment is filled when connected.

In order to allow the segment to be filled, when the latter uses an air-return type spray pump, an air release mechanism is provided for the segment, before filling the segment with the contents again. of the container. However, the device with such mechanism does not return the liquid product segment in the container.

It is also known to use in this segment, or in a similar separable sprayer, a type of spray pump without air intake, which allows to create in said segment a depression which provides for the subsequent filling of said segment. The use of a pump of this type with a separable sprayer is described, for example, in the published French patent application FR-A-2 854 131. In this case, the pressure inside the filling container of liquid product is substantially equal to or less than the atmospheric pressure. However, it is also impossible to return the liquid product of the segment into the container.

It has been found that certain liquid products, particularly perfumes and the like, may be subject to changes or loss of their original characteristics over time, more rapidly in the refillable segment than in the container. Therefore, it would be desirable that the user can return the liquid product of the rechargeable segment in the container, easily and without loss of product, when it does not need to have it available. The present invention provides for it.

Meilleure manière de réaliser l'inventionBest way to realize the invention

Referring first to Figures 1 and 2 of the drawing, numeral 10 represents a bottle or bottle for containing a liquid product, which is shown in gray, at the bottom portion of the bottle. This bottle 10 is provided with a refillable sprayer 11, which is arranged to be detachably housed in a recess 12 preferably disposed at the upper part of the body of the bottle 10. Appropriate staples may be provided on the sprayer 11 or in the recess region 12 to removably fix the sprayer 11 in the recess 12.

The sprayer 11 has a body which is prismatic in shape and has opposite end walls 13 at a distance from each other (only the front end face is shown in the figures) and the peripheral walls 14 connecting the walls. 13 opposite ends. The sprayer body forms a cavity, which is adapted to be at least partially filled with the liquid product from the bottle 10. This cavity in the sprayer body communicates with a tubular valve member 15, wherein the product liquid can pass.

Preferably, the tubular member is rotatably connected to the sprayer body so that it can be rotated by the user between a lowered operative position, as shown in FIG. 2, and a raised non-operative position. wherein the tubular member is received within a suitable recess 16 of the lower peripheral walls 14 of the sprayer body, as shown in FIG. 1, and closes a passageway leading to the cavity of the sprayer body.

A tubing 17 is provided inside the body of the bottle 10, to allow the passage of the liquid product between the bottle 10 and the sprayer 11. An end portion of the tubing 17 is submerged in the liquid contained in the body of the bottle 10 and the opposite end portion of the tubing 17 leads to an opening 18 at the bottom of the recess 12 and is adapted to be received within the tubular element of the sprayer 11. This opening 18 can be conveniently provided with a removable cap (not shown) or other sealing means, capable of providing a seal, when the sprayer 11 is removed from the recess 12.

The end walls 13 of the sprayer body, which are normally spaced apart from each other, are made of a flexible and flexible material so that they can move toward each other under the pressure of the fingers. or following a depression created inside the cavity, and to make a return movement, when the pressure of the fingers is released or said depression becomes zero. The peripheral walls 14 of the sprayer body are however in a rigid material, since they do not have to be flexible and elastic. The design details and materials used for the end walls 13 and the peripheral walls 14 may vary.

In order to cause the passage of the liquid product in the sprayer 11, assuming that it does not contain the liquid product as shown in Figure 1, the user must remove the sprayer 11 from its chamber 12 of the bottle 10 and put the tubular member in the lowered operative position, as shown in FIG. 2. Then, the user presses the sprayer 11 into the region of the end walls 13 of the sprayer body to expel the air at the same time. the interior of the sprayer body by the tubular member, thereby creating a vacuum within the cavity of the sprayer body. While keeping the body of the sprayer compressed by finger pressure, the user then returns the sprayer 11 to its chamber 12 and, in doing so, inserts the tubular element completely into the open end of the tubing 17. At this point, the user can release finger pressure. This causes the liquid product in the bottle 10 to be drawn through the tubing 17 and the tubular member into the cavity of the sprayer body as shown in FIG. 3. Finally, the user removes the sprayer 11 of its housing in the recess 12 and returns the tubular member in the non-operative position raised within its recess 16 of the body of the sprayer. The sprayer 11 can now be used to dispense the liquid product onto the user's body while the user is in motion.

As can be seen in FIG. 4, the sprayer 11 is provided with a spray button 19, preferably placed on the upper peripheral wall 14 of the sprayer body. This spray button 19 operates a spray pump inside the sprayer 11, so that the liquid product is sprayed through a suitable spray nozzle, preferably placed on one of the end walls 13.

This spray pump can be of the type with or without air intake. In the latter case, the sprayer is filled through a suitable filling valve (not shown) which is in sealed communication with a collection tube of the bottle 10 separate from the tubing 17. However, with a pump without resumption of air, the user does not need to compress the sprayer 11 to expel the air inside the body of the sprayer after the first filling and use, since the depression created inside the body of the sprayer induces the suction of the liquid product contained in the bottle 10 in the subsequent filling. In addition, the deformation of the flexible walls caused by the depression inside the sprayer cavity indicates to the user when the liquid product is at an end.

An important aspect of the invention is that it allows the user to return the unused liquid product from the sprayer 11 to the bottle 10 through the tubular member. This can be done as follows. First, the user places the tubular member in the lowered operative position and returns the sprayer 11 into its recess 12 of the bottle 10, so that the tubular member is inserted over a substantial portion of its length into the tubing 17. Then, the user compresses the sprayer 11 in the region of the end walls 13, so as to create a pressure inside the cavity of the sprayer 11, which makes the liquid product contained in the sprayer 11 returns in the bottle 10 passing through the tubular element and the tubing 17.

Ideally, the liquid product contained in the bottle 10 can be dispensed by the sprayer 11, when it is housed in the recess 12 of the bottle 10. In another embodiment, the bottle 10 can also be provided with a separate dispensing mechanism, which allows to distribute the liquid product, when the sprayer 11 is detached from the bottle 10. In this case, the bottle 10 is provided with a spray button 19 and a nozzle 20 for dispensing the product liquid.

Although the invention has been described according to an embodiment given by way of example, it goes without saying that many variations and modifications, which will become apparent to those skilled in the art, can be carried out without departing from the scope. of the invention.
