OBJECT OF THE INVENTION.
[0001] The object of the present invention is a pressurised gas sprayer, of among the atomizers
or sprayers intended for the diffusing of a liquid contained in a recipient in an
atomised form.
[0002] The present invention is characterised in that it is capable of achieving the high
pressure spraying of the liquid contained inside a recipient due to a gas which, when
expanded, produces an interior high pressure without the liquid inside being discharged
mixed with the gas in any way in the spraying.
[0003] Therefore the present invention lies within the ambit of the atomising or spraying
of liquids contained in recipients, in which the diffusion is carried out at high
pressure.
BACKGROUND OF THE INVENTION.
[0004] There are numerous inventions existing on the market which disclose systems of pressurised
spraying, using for this a recipient inside which are held in a separate manner both
the liquid contained in the interior thereof and a gas at high pressure.
[0005] An aerosol or spraying device is known in which the distribution of the liquid contained
in its interior is effected propelled by a gas which is at high pressure in the interior,
both the product to be dispensed and the gas being discharged together.
[0006] For this purpose, in the interior of the container a cartridge is mounted which has
inside the product to be dispensed. Inside the cartridge there is a piston, which
constitutes the bottom of the cartridge once the latter is full. The space lying between
the external container and the cartridge of the product to be dispensed is filled
with pressurised gas, refilling being possible through the lower part of the assembly.
[0007] This system has the drawback of complexity in the construction of the assembly of
the device in order to be able to dispense a product, wherein also the dispensing
has necessarily to be carried out in a joint manner of the product and the gas.
[0008] Other systems of delivering products by means of sprayers with the objective of being
able to carry out the spraying at high pressure have abutting upon the actual dispensing
gun some means of supplying gas to the interior of the internal receptacle with the
objective of pressurising the container.
[0009] These systems have the drawback of having to effect the continuous pressurisation
of the container, said pressurising means having to be continuously abutting upon
the dispensing gun.
[0010] Therefore, it is an objective of the present invention to overcome the aforesaid
drawbacks, developing for this a pressurised gas sprayer, in which the distribution
of the product to be dispensed is not carried out in a manner mixed with gas, wherein
also the means of pressurising the internal product are not abutting upon the delivery
gun.
[0011] It is known from the State of the art a pressure container as the one disclosed in
DE 4039632, in the pressure container there are two different chamber, a fluid chamber and a
gas chamber being keyed engagement, having the gas chamber an inlet valve, and means
for emptying the pressurises gas contained within. Now the objective of the present
invention is to overcome the drawback derived from the structure of the pressure container
disclosed in
DE 4039632, which is the fact of being necessary additional emptying means for dispensing the
gas into the fluid chamber. This drawback is overcome in the invention.
DESCRIPTION OF THE INVENTION.
[0012] The disclosed invention of a pressurised gas sprayer basically consists of a recipient
container of the product to be dispensed in the interior of which is housed a refillable
reservoir of pressurised gas.
[0013] Said refillable gas reservoir is fastened to the dispensing means, namely the activating
trigger and the discharge valve, and it is mounted so that when the dispensing means
are fastened on the recipient container the compressed gas reservoir is left on the
inside of said recipient container.
[0014] The refillable gas reservoir has a double-acting valve for filling and emptying and
is connected by means of a wire or tape with a seal arranged on the body of the dispensing
means.
[0015] Through said seal it is possible to completely empty the gas from the reservoir to
the container or bottle, wherein the liquid is contained, increasing the internal
pressure of the bottle from 1 atmosphere to 3 atmospheres.
[0016] By acting on the dispenser trigger pressure is applied to a discharge valve causing
the liquid contained at high pressure inside the bottle to escape under pressure to
the exterior.
[0017] The liquid in the interior of the bottle escapes to the exterior without being mixed
with the gas, since a small tube connects the discharge valve with the bottom of the
bottle where there is always liquid until its exhaustion.
DESCRIPTION OF THE DRAWINGS.
[0018] To complete the description that will be given below and with the object of assisting
in a better understanding of the characteristics thereof, the present descriptive
specification is accompanied with a set of drawings in figures of which, by way of
illustration and not restrictively, the most significant details of the invention
are represented.
[0019] Figure 1. It shows a representation of the pressurised gas sprayer object of the
invention wherein the main elements which form the same are observed.
PREFERRED EMBODIMENT OF THE INVENTION.
[0020] In the light of the aforementioned figures a description of a preferred method of
embodiment of the invention disclosed is given below.
[0021] In figure 1 it can be observed how the pressurised gas sprayer is formed by a pressurised
gas reservoir (1) abutting upon the body (10) wherein the dispensing means (10) are
located in such a way that with the dispensing means fastened on the bottle, the gas
reservoir (1) remains on the inside of the bottle.
[0022] Moreover, the pressurised gas reservoir (1) has a double-acting valve (2) which allows
the filling with and emptying of the gas contained in the interior thereof. Said valve
(2) is connected by means of a wire or a tape (3) with a seal (4) mounted on the body
(10) of the dispensing means, so that by acting on said seal and pulling on the wire
or tape (3) the discharge of the gas contained in the reservoir (I) takes place into
the interior of the bottle, achieving the pressurising thereof, producing an increase
in pressure from 1 atmosphere to 3 atmospheres approximately.
[0023] On the other hand and with the object of achieving the distribution of the liquid
inside, the device has an activating trigger (5) which presses on a discharge valve
(6) which is connected by means of a small tube (9) with the bottom of the bottle
wherein the liquid to be dispensed is located, in this way the spraying of the interior
liquid is achieved at high pressure without it being mixed with the gas, escaping
through a diffuser (7).

- A body (10) in which dispensing means are mounted,
- Dispensing means consisting of a trigger (5) which presses on a discharge valve
(6) which in turn is connected with a small tube (9) which extends to the bottom of
a bottle container containing liquid,
- An external seal (4) mounted on the body of the dispensing means,
characterised in that:
- a gas reservoir (1) is joined to the body (10) of the dispensing means, so that

gas reservoir with gas.
- The external seal (4) is connected to the double effect valve (2) through a wire
or a tape.
whereby the sprayer allows the spraying of the liquid contained inside the bottle
which escapes through a diffuser (7) without being mixed with the gas.
