Patented Aug. 10, 1954 PLASTIC PRESSURIZED CONTAINER AND DISPENSER Ralph D. Cooksley, Elizabeth, N. J., assignor, by

mesne assignments, of one-half to Packaging Corporation,

ration of New Jersey Application September 24, 1953,

4 Claims.

This invention relates to a plastic pressurized container of a type ada ted to contain a liquid or gas under pressure and having a manually opleirable valve to dispense the fiuid therefrom at W1 It is an object of the invention to provide a pressurized container which has substantially all It is another object of the invention to provide a plastic pressurized container wherein the plastic parts will be assembled by hand without mg from the end of the cap and manually depressible by a finger to permit the release of the fluid past the protruding stem of the valve element upon the same being depressed and wheremember.

It is another object of the invention to pro vide a plastic pressurized container adapted to be filled with the use of a special filling head that may dispense the pressurizing gas, such as Freon, without the need for refrigeration to maintain the stability of the gas while passing it to the container.

Other objects of the invention are to provide a plastic pressurized container which is of simple construction, durable and so proportioned a to For a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure l is a vertical sectional view of the container with the cap and its valve parts asscmbled thereon;

Fig. 2 is a perspective view of the container with the cap broken away to show the interior construction of the valve.

tion as when the container is being filled.

Generally, the invention comprises a valve stem of different diameters assembled in the cap such a way that when the valve stem is completely depressed or in the filling position there is a sufiioiently large orifice to permit rapid and low pressure filling; after the container has been filled and the valve stem is in the operating position for dispensing, the middle diameter or metering portion is located in the choke area of the plastic cap with a very close tolerance. The cover cap or cover is so designed that during the dispensing action the middle circumference of the valve stem cannot be depressed out of the choke area and, therefore, the product can be dispensed in very small quantities with a short and highly atomized display pattern which is very desirable for personalized products.

Referring now to the figures, Ill represents a round container body portion having a bottom it and an internally threaded open upper end 12. Adapted to be secured to the internally threaded open upper end is a cap I 3 having a depending externally-threaded sleeve portion [4. Upon the cap being assembled with its parts, it is permanently secured to the upper end of the container i it by cement so as to prevent the same from being loosened and to render the container fluid-tight. The threads also avoid the neces sity for any jig or fixtures to hold the parts together until the cement sets, reduces assembly costs, and adds immeasurably to the strength of the container. The exterior of the cap I 3 is serrated, or ribbed, as indicated at IE to provide a good hand grip to tighten the cap upon the container body It. Both of these parts are formed of rigid thermoset plastic material.

The cap it has a central opening [6 extending therethrough and terminating in a depending threaded sleeve portion I! to which a bottom funnel and spring retaining member l8 or adaptor is threadedly connected. This makes an easy hand assembly and makes it unnecessary to cement the adaptor due to the equal pressure inside the adaptor and the container which would tend to prevent transmission of the fluids between the adaptor and the container. Thi retaining member i8 is also of plastic and has a hole 99 extending through its lower end and through a reduced diameter portion 20 to which there is fitted a piece of flexible plastic tubing providing a syphon tube 2| that leads to the bottom of the container l0 and which has a hole 22 in its lower end to prevent the end of the syphon tube from ever being blocked ofi by being bottomed on the bottom of the container.

Extending upwardly from the top of the cap 13 is a nozzle projection 23 which forms the body of the valve itself and is an integral part of the cap and eliminates soldering, menting a valve as such into the container, thereby reducing construction costs. 23 has a tapered upper end Zlwith an'aperture 25 therein. This aperture 25 is of a diameter adapted to receive an intermediate portion 26 of a valve element 21. This aperture 25 is of adiameter made to receive valve portions close tolerance to provide the choking or metering effect of the valve when in the dispensing position. This valve element has a-rubber 'seal-- ing sleeve 28 surrounding the portion at the I root of the same that has its lower edge fitted into an annular groove 2c in an enlarged diameter portion 38."

Withinthe dependingsleeve member i8 a spring 3! preferably made of stainless steel and which bears against bottom enlargement iii of the'valve element 21. The valve element has a depending stem 3! to help keep the spring 32 centered.

Extending upwardly beyond the portion 2B of the valve element 2'! is a stem 33 of reduced diameter which i depressed into the aperture to form a large entrance into the container in the manner as shown in Fig. 3 and by a special pressure filling head indicated generally at A.

An over cap or cover member formed of a flexible plastic or rubber is indicated at 34 and is snapped over the nozzle 23 and fitted in tight sealing relationship due to a flange 23' which snaps into a groove on projection 23. A large flange 35 fits into an annular recess 35 in the top of the cap 13. The top of the over cap 34 base thin membrane 3'5 that is pliable and can be depressedby a finger, as illustrated in Fig. 2. However, the over cap 34 is designed in such a way that the stem cannot be depressed far enough to get-portion 26 on the stem out of aperture 25 "in the cap. This maintains the metering of the productwhen being dispensed. The stem 33 of the valve-element engages the underside of this membrane 3'? and accordingly when the membrane is pushed downwardly against the action of spring 3! to cause the rubber seal 28 to be lowered and allow the product to pass through the choke area of the valve. Upon release of the finger, the valve element will be returned so 'that'the portion 25- andthe rubber ring or sleeve 28 will positively seal off the aperture 25 from the underface of the tapered end'oi the'nozzle 23. Since the over cap or cover member is duringthe filling'operation, it ispossible to depress the small diameter of the stem into the choke area and remove the choke portion of the stem out of the way. The-valve element 21 is made of nylon or'other similar plastic and is molded to close tolerance.

On the over cap 34' is a small nozzle element 38 formed of hard plastic and having an aperture 39 through which an atomized spray will be projected upon depressing the valve element 2?. This nozzle element 38 has a flange'de engaging the outer face of the cover cap 34. This small nozzle element 38 is formed of hard plastic so that the aperture '39 is not closed.

It should now be apparent that there has-been.

As the aerosol industry grows, and especially in the direction of the cosmetic trade, it will be possible, using this type of container, to furnish a wide variety of shapes and colors which will mean a freedom of design to indicate the individual products that are prevalent today from a pachagingstandpoint in the cosmetic industry. A great-many cosmetic houses have refrained from exploiting the possibilities in the aerosol field as they refuse to put their product, as they say, in a beer can.
