VALVE DEVICE FOR AEROSOL VESSEL Filed May 31, 1962 INVENTOR ATTORNEY United States Patent 3,186,683 VALVE DEVIQE FOR AEROSOL VESSEL Masayoshi Azechi, 141 l-chome, Katuyama-dori, Tennojiku, Osaka, Japan Filed May 31, 1962, Ser. No. 198,880 Claims priority, application Japan, Apr. 19, 1962, 37/ 16,199 1 Claim. (Cl. 251-342) The present invention relates to a valve device of aerosol vessel. As is well known, the valve closes the content of pressure within the aerosol vessel without leakage when the content is not used, and it releases the content of pressure out of the aerosol vessel smoothly when the con tent is used.
Conventional valve devices for aerosol vessels are very much complicated in mechanism and very much rich in variety. And in most cases, the valve device is provided with a mounting cup, a valve housing projected within the mounting cup, a dip tube engaged with the valve housing, a rubber sheet inserted in the valve housing, a shoulder cup engaged with the rubber sheet by means of a spring, a valve stem connected to the rubber sheet and projected outwards, and an actuating button set on the valve stem. By pushing the actuating button the rubber sheet is deformed in such a manner that a spray is released from between the rubber sheet and the shoulder cup.
It is never an economical fact that such a developed valve device as above described is always thrown together with the vessel itself after the vessel is emptied of the content.
The present invention aims to provide a simple and economical valve device for aerosol vessel. It is not inferior at all in function to the conventional ones. More particularly, the valve device of the present invention is composed only of a mounting cup, a projected cup in the middle of the mounting cup, and an actuating button. It is not equipped with any of valve housing, rubber sheet, shoulder cup, valve stem and spring.
Referring to the drawings which are for illustrative purposes only;
FIG. 1 is a sectional view showing the closing state of a valve device, an embodiment of the present invention, which has a projected cup in the middle of the mounting cup made of a different material from the projected cup, and an actuating button is provided over it.
FIG. 2 is a sectional view showing the spraying state of the valve device shown in FIG. 1.
FIG. 3 is a sectional view showing the closing state of a valve device, another embodiment of the present invention, which forms a projected cup in the middle of the mounting cup, and an actuating button is provided over it.
FIG. 4 is a sectional view showing the spraying state of the valve device shown in FIG. 3. V
In the present invention, a projected cup A, which is made of a material different from that of the mounting cup L, is provided in the middle of the mounting cup L (the lid of the vessel), or a projected cup B is formed, by projecting the mounting cup L itself, in the middle of the mounting cup L. And an eyelet A or B is provided at the top of the projected cup A or B. Also provided is an actuating button which is made of elastic material such as rubber or synthetic resin, and the actuating button is equipped with a tongue piece E inside the upper part thereof and with a nozzle F at one side of the upper part thereof. The clip tube C is inserted into the projected cup A or B. I
In the valve device of the present invention as above described, the eyelet A or B is firmly closed, as shown in FIG. 1 or 3, usual case when it is contacted with the tongue piece E. But when the actuating button is pushed sidewards by the thumb, the tongue piece E is put out of the contact with the eyelet A or B, as shown in FIG. 2 or 4, so that the contained liquid is released from the dip tube C through the eyelet A or B, and then sprayed through the nozzle F after going round the tongue piece E.
When the pushing thumb is removed oil, the actuating button will naturally recover to the original form and position, because it is made of an elastic material, so as to close the eyelet with its tongue; thus the spraying is stopped.
In the present invention, the eyelet (the outlet for contained liquid) is closed or opened by the tensile stress and elasticity of the body of actuating button. The valve device of the present invention, therefore, does not need the valve housing, spring, shoulder cup and rubber sheet all of which are indispensable to the conventional valve device. Such is 'a great feature of the present invention.
The pressure will be around 5 lrg./cm. within the aerosol vessel. As for the elastic material for actuating button, even vinyl chloride which is lowest in strength against pressure can stand against a pressure over 70 kg./cm. and natural hard rubber can stand against a pressure around 700 kg./cm.
It can be said from the above fact that the eyelet A or B is kept pressed certainly enough with the tongue E. The tip of the tongue E is good, therefore, to be made of the same material as the button body itself.
What I claim is:
A valve device, comprising, in combination: a mounting cup for mounting the valve device to control fluid flow from a container; a projection cup-having an eyelet of a diameter substantially smaller than that of the projection cup at the top of the projection cup and connected to said mounting cup and adapted to be connected to a source of pressurized fluid; and a hollow actuating button connected to said mounting cup to cover said projection cup and enclosing the projection cup between the actuating button and the mounting cup, said actuating button including a tongue projecting downwardly from the top of the actuating button, said tongue having a convex rounded tip which extends to form the sole means for sealing the eyelet, the contact area between the projection cup and said rounded tip being only slightly larger than the area of the eyelet, said actuating button forming an annular chamber about said contact area which extends upwardly about the tongue and downwardly about the projection cup for part of the length of the, latter, said actuating button having an opening therethrough in communication with said annular chamber, said button being made of an elastic material thereby to be deformed upon the lateral application of exterior force to move the tongue from over the eyelet to permit flow of fluid through said eyelet into said button and out through said opening.
