Description

Pressure regulator for spray cans and membrane herewith applied.
---------------------------------------------------------------------------------------------------------------
This invention relates to a pressure regulator for spray cans, especially a pressure regulator which makes use of a valve that is placed between a reservoir which is destined to be filled with a gas under high pressure and the useful reservoir of the spray can, and of a membrane that commands the valve. The invention also concerns the membrane which is applied for this.
It is known that a spray can may be equipped with a pressure capsule in order to put the medium to be dispersed under pressure. Such a pressure capsule consists mainly of a pressure reservoir that is destined to be filled with a gas under high pressure and a pressure regulator which releases gas out of the pressure reservoir into the useful reservoir of the spray can such until a well defined pressure, necessary for the dispersion of the medium, is created. The pressure regulator also then holds the pressure in the useful reservoir constant.
As known, such a pressure regulator lias a movable wall, such as a membrane, which can work together with the valve body of the aforementioned valve. With the known embodiments the movable wall is put under pressure on the one hand through the pressure which is created in the spray can and on the other hand through elastic means which act on the membrane, which either consist of a spring placed in an closed chamber, or of an amount of compressed gas at a well defined pressure which is notably higher than the atmospheric pressure, or through a combination of both.
These known pressure regulators show the disadvantage that their construction is relatively expensive, considering that in an automated fabrication process special means have to be foreseen either for the placing of the aforementioned springs, or for the filling of the chamber situated on one side of the membrane with gas under pressure. With fabrication of spray cans it is also a primary requirement for economic reasons that they may be manufactured with a minimum of fabrication steps.
The present invention also then relates to a pressure regulator for spray cans which can be manufactured in a particularly easy manner, whereby the aforementioned step, either the placing of the spring, or the installation of a well defined pressure in a space situated along one side of the membrane, is excluded.
For this purpose the invention consists of a pressure regulator for spray cans, in particular which make use of a valve that is placed between a reservoir that is destined to be filled with a gas under high pressure and the useful reservoir of the spray can, and of a membrane which commands the valve, with the characteristic that the pressure regulator has a membrane that mainly through its own elasticity provides the control operation of the valve. In the most preferable embodiment the pressure regulator then also shows no other single separate means that is special destined for the production of a well defined counteracting force on the membrane.
The desired magnitude of the control force can be achieved for example by adjusting the thickness of the wall of the membrane, by prestressing the membrane, or also by adjusting the displacement of the membrane before the valve 9 is closed.
The membrane consists preferably of plastic. In the most preferably embodiment use is made of polyacetal or a plastic on base of polyacetal. Also other plastic such as polyamides, polysulphon and polypropylene may be used.
In order to better show the characteristics according to the present invention, some preferred embodiments are described hereafter, as examples and without any restrictive character with reference to the enclosed drawings, in which: figure 1 shows in cross-section a spray can which makes use of a pressure regulator according to the invention;
figure 2 shows the spray can from figure 1 for another position of the pressure regulator;
figure 3 shows a variant of the invention.
In figure 1 a spray can with a pressure capsule is shown schematically. The spray can consists, as known, of a reservoir 1 for the medium 2 to be dispersed, a valve 3 to disperse the medium 2, and a push button 4 to operate the valve 3 which is provided v/ith an outlet such as a spray opening 5. The pressure capsule which works together with the spray can consists mainly of a pressure reservoir 6, which is for example provided with a filler opening 7, and a pressure regulator 8. The pressure regulator 8 consists mainly of a valve 9 and a membrane 10 which can command the valve 9. The valve 9 consists of a valve body 11, placed in the passage 12 between the pressure reservoir 6 and the reservoir 1 and connected with the membrane 10 via a valve spindle 13. The passage 12 first exits in a chamber 14 which is connected with reservoir 1 via openings 15. The ring 16 hereby exclusively performs the function of nonreturn valve.
A chamber 17 is situated above the membrane 10 which prevents the pressure out of the reservoir 1 from acting on the top of the membrane 10.
The particularity of the present invention consists in that the pressure regulator has a membrane that mainly through its own elasticity provides the control operation of the valve 9. As explained in the introduction this offers the advantage that no springs need to be installed in the chamber 17, nor a gas under a well defined pressure need be provided. It is also clear that an atmospheric pressure normally prevails in the chamber 17, such from during the assembly, which is however to be disregarded concerning the control operation.
In figure 2 the operation of the pressure regulator is shown. Hereby the pressure reservoir 6 is put under pressure with the result that the chamber 14 and the reservoir 1 are filled with gas from the pressure reservoir 6, whereby the membrane 10 is elastically stretched out to the position according to figure 2, the downward force as a result of the elasticity of the membrane 10, by the construction of the membrane, is so cnosen that the valve 9 reopens as soon as the pressure in the reservoir 1 falls under a defined value.
In figure 3 another variant is shown whereby the membrane has two functions, and is produced in the form of bellows.
With the depression of the bellows the wall 18 of the filled pressure reservoir 6 is pierced, through which the pressure regulator 8 is set in operation. The closing of the valve 9 is nearly exclusively determined by the counteracting force caused by the elasticity of the membrane 10.
In the most preferable embodiment use will also be made of a membrane 10 as shown in figure 1, that is circular and that shows a ring shaped part 1 9 wit h an arched cross-section .
The present invention is in no way restricted to the embodiments described as examples and shown in the drawings , but such pressure regulator for spray cans , and the membrane used herewith, may be developed in all kinds of forms and dimens ions without departing from the scope of the present invention.
