Definitions
- the so called aerosol containers for these products are generally provided with a valve which is; biased closed by a spring, and forced open by manual operation, as for example, by finger pressure. Due to the required dimensions for the valve, and in particular, the valve body and valve seat, the pressure acting on Ithe valve, i.e., the pressure of the propellant gases of the aerosol prod- -uct are not sufficient to force and maintain the valve closed and in all cases, the spring is absolutely necessary to eifect Athe closing actuation and to maint-ain the valve sealed. Furthermore, in the conventional aerosol valve, the distance from the valve seal to Ithe outlet opening of the container is relatively long which may interfere with the quality of the spray produced.
- One object of this invention is a novel aerosol valve construction which may solely -rely on the pressure of the propellant for the closing and sealing actuation.
- a further object of this invention is an aerosol valve which may be manufactured much more cheaply than the conventional aerosol valve.
- a still further object of this invention is an aerosol valve in which the path from the valve seal to the outlet opening is relatively small, whereby a good spray effect is obtained.
- Fig. 1 is Va vertical section of an ⁇ embodiment of an aerosol valve, in accordance with the invention, positioned in place on an
- Fig. 2 is a vertical section of the valve shown in Fig. l in its closed position
- Fig. 3 is a vertical section of the valve shown in Fig. 1 in open position
- Fig. 4 is a vertical section of -a further embodiment of an aerosol valve, in accordance with the invention, positioned in place on -an aerosol container neck.
- valve body which is positioned for sealing engagement with the valve body and which may be manually Iactuated out of sealing engagement with the valve body Iand a movable diaphragm connected to the valve seat and positioned to be acted on by the pressure inran aerosol container to which the valve is attached to resiliently force the valve seatY in sealing engagement with the valve body.
- the valve preferably is in the form of a hollow body, having a resilient wall portion defining a diaphragm, with a valve seat connected thereto as, for example, defined on a neck, forming an extension of the body.
- A11 outlet ice passage is dened Kfrom the interior of the hollow body through the valve seat and a valve body, such as a valve cone is positioned on a valve stem extending through the hollow body for sealing engagement with the valve seat.
- the valve seat may be manually moved out of sealing engagement with the valve body against the fluid pressure in the interior of said hollow body, as for example, by finger pressure applied to a cap positioned on the neck which define-s the valve seat.
- 1 represents a container or can which contains the aerosol product with the pressurized propellant gas.
- the aerosol valve is positioned in the neck portion 2 of the container.
- the valve consists of a hollow valve body preferably for-med of a flexible synthetic resin such as a polyamide, polyethylene or the like and having a lower section designated 3, and an upper section, designated 4.
- the lower ⁇ Section has a cylindrical portion 3a and ⁇ a conically narrowing portion 3b.
- the upper portion has a cylindrical wall portion 4a and an elongated cylindrical, slightly tapering neck 4b which defines, at its upper end, the conical valve seat.
- the neck portion 4b is connected to the cylindrical wall portion 4a by means of a resilient upper wall portion 8 which forms a diaphragm.
- the lower portion of the section 3 has a cylindrical tubular extension 15 -to :which the hose or dip tube 16 is connected.
- a stationary valve stem 5 is connected to the bottom portion 14 of the section 3 and extends upwardly through the hollow interior of the body and through the neck 4b.
- the conical valve body 6 Positioned at the end of the valve stem 5 is the conical valve body 6 which is in sealing engagement with the valve seat defined at the end of the neck portion 4b.
- the hollow body 3 4 is firmly seated in sealing engagement with the container neck 2 with the lower conical portion 3b and cylindrical portion 3a of the body 3 pressed in contact with the neck and with the upper end of the neck flanged over the hollow body at 1b.
- a metal cap 17 may 4be provided to hold the body in place and reinforce the neck portion of the container.
- the topy of the cap 7 is pressed, as :for example, with yartinger, forcing the neck portion 4b downwardly with an inward flexing of the diaphragm S against the pressure in the interior of the hollow body 3-4.
- the yforcing downwardly of the neck portion 4b moves the valve seat at the end thereof away from the conical valve body 6 so that the valve is opened and contents of the aerosol container by means ofthe pressure of the propellant will be forced up through the dip tube 16, the interior of the connection 15, the interior of the hollow body 3 4, the neck 4b, pastvthe valve seat through the hollow passageway '-11, the nozzle 13 ⁇ and same is sprayed through the discharge opening 12.
- the downward movement of the neck 4b and valve seat at the end thereof is limited by the projection 10 Icoming in contact with the top ⁇ of the conical valve body 6 as is shown in Fig. 3 which depics the valve in the open position.
- the diaphragm-S can Vbe increased in size as desired so that the closure pressure acting on the valve through the diaphragm 8 maybe made as large as desired withont the necessity of a spring.
- a spring may also be employed, lbeing positioned, for example, between the diaphragm and the bottom 14 of the body portion 3.
- rEhe valve i.e., the conical valve body 6 and the engaging valve seat
- the passage 11 which is annularly shaped due -to the projection 1G, provides an eddying of the flow stream emerging therethrough, so that excellent atomization maybe obtained at the outlet opening i rhe embodiment as shown in Fig. 4 is identical in construction and operation except in the manner in which the body 4 is secured to the neck of the container.
- the portion 4 of the hollow body may be provided with an annular ange ⁇ 18 and cylindrical collar 19".
- the outer sunface of the cylindrical collar 19 is pressed in sealing engagement with the inner surface of the cylindrical neck of the aerosol container and the flange ES and collar 19 may be provided with a rigid closure piece 2l. which fits in an annular recess 20 in the section 4 of the hollow body.
- the upper end of the CTL collar 19 and closure piece 21 may be clinched in place at @a as shown inthe left hand part of Fig. 4 or ilanged in place as shown at b in the right hand part of Fig. 4.
- the closure part 2i should be rigid enough and secured in place so that the pressure in the container does not cause movement of the same or the hollow valve body and only acts upon the diaphragm.
- the construction in accordance with the invention, provides a great savings ⁇ in manufacturing costs, the manufacturing costs being only about one-tenth to one-fifth of the manufacturing costs of the conventional aerosol valve. Furthermore, the construction allows a better spray effect to be obtained and in eliminating the need for the spring, not only is the cost thereof avoided, but failure caused by corrosion of the spring by the aerosol product is eliminated. By suitable adjustment of the diaphragm 8 without the use of the spring, it is possible to make the valve closure pressure as large as desired.
