Definitions

  • ABSTRACT A valve for delivering a liquid from an aerosol container, comprising a rigid body member seamed to a bottom attachable on a container mouth or inlet and having side and bottom walls defining a cavity, a first [451 July 16, 1974 shutter which is accomodated and movable within the cavity of said rigid body member, a tubular element having one end projecting from the bottom on the opposite side to that from which said body member projects and its other end fast with said first shutter, a resilient sealing member between the rigid body member and the bottom and having a hole, in which said tubular element is forced and can move and swing, at least one passage between the inside of the tubular e1- ement and the cavity of the rigid body member adjacent to said first shutter, at least one free hole in said side wall of the rigid body member, at least one spring acting on the first shutter by pressing it against said sealing member to close said passage, a hole being provided in the bottom wall of the'rigid
  • Ordinary aerosol containers have a liquid therein, directly contacting a propelling gas, the latter imparting the required pressure to the liquid for a violent ejection thereof through the nozzle of a delivery valve which is applied to the container.
  • a direct contact between the propelling gas and liquid to be delivered is absolutely undesirable and therefore is to be avoided on the whole.
  • the liquid being delivered through valves applied to these containers is mixed with the propelling gas.
  • Containers are also known as provided with valves, through which a liquid can be delivered by the action of a propelling gas, without any mixing or direct contact of the liquid with said gas, but in addition to being ofa rather complex structure, such valves requirethat the propelling gas is introduced into the container prior to seaming thereon the bottom to which the valve is applied, with a somewhat complex and expensive procedure.
  • the introduction of the propelling gas is accomplished through a hole in the bottom of the containers.
  • the main object of the present invention is to provide a valve which can be applied to an aerosol container and suitable to keep as separate a liquid to be delivered from the valve and a propelling gas within the contamer.
  • Another object of the invention is to provide a valve of the above character which, after being sealingly applied to a container, will allow for directly introducing the propelling gas into the container through said valve, avoiding any contact thereof with the liquid in a de- 4 formable bag which has been previously mounted on cavity, a first shutter which is accomodated and movable within the cavity of said rigid body member, a tubular element having one end projecting from the bottom onthe opposite side to that from which said rigid body member projects and its other end fast with said first shutter, a resilient sealing member clamped between the rigid body member and the bottom and having a hole, in which said tubular element is forced and can move and swing, at least one passage between the inside of the tubular element and the-cavity of the rigid body member adjacent to said first shutter, at least one free hole in said side wall of the rigid body member, at
  • FIG. 1 is an axial sectional view showing a valve mounted on a container, the valve being at a rest conditron;
  • FIG. 2 is a sectional view of the valve at operative or I delivery condition
  • FIG. 3 is a sectional view showing a valve as apropelling gas is being introduced into a container, on which said valve is mounted;
  • FIGS. 4, 5 and 6 are still axial sectional views showing respectively, a second embodiment of the valve at a rest condition and at an operative or delivery condition, and as a propelling gas is introduced under pressure into a container on which the valve is mounted;
  • valve respectively, at rest, operative or delivery conditions, and as a propelling gas is being introduced into a container, of which said valve is a part.
  • FIGS. 1-3 a first embodiment of the valve is shown therein.
  • a rigid body member having a side wall 4 and a bottom wall 5 defining a cavity within said rigid body member
  • a first shutter 7 and a second shutter 8 are ac.-
  • said finger 10 can oscillate in recess 9, causing the second shutter to oscillate, as a result of a sidewise oscillation of the first shutter.
  • a spring 11 is also accomodated within the cavity defined by said walls 4 and 5 of the rigid body member, one end of this spring abutting on a collar projecting from shutter 7, and the other end of the spring abutting on a collar projecting from FIGS. 7, 8 and 9 are axial sectional views for athird shutter 8, said spring acting to urge said two shutters away from each other, that is tending to retain the two shutters at the position as shown in FIG. 1.
  • a cavity is provided and a plurality of radial ribs 12 project therefrom, one end of a tubular element 13 being forced and clamped therebetween, which tubular element 13 is forced, movable and swingable through a hole provided in seal 6, and has its other end projecting from bottom 1 on the opposite side to that from which said rigid body member of the valve projects.
  • At least one hole 14 is provided in the side wall 4 of said rigid valve body member, whereas a further hole 15 is provided in the bottom wall 5, at which a hollow extension 16 projects and has the inlet 17 ofa deformable bag 18 mounted thereon, this bag 18 being made, for example, of plastic material or rubber.
  • This inlet 17 of bag 18 is somewhat elongated and extends on the side wall 4 of said rigid valve body member, overlying said hole 14 and sealing the same.
  • annular resilient strip which can be superimposed on the-outer surface of the sidewall 4 and seal the hole 14 in the sidewall.
  • the annular resilient strip is integrally formed with the bag 18.
  • the annular resilient strip can be formed as a distinct, resilient ring which is not an integral part of the bag.
  • shutter 8 is pressed on the bottom wall of the rigid body member of the valve and closes hole 15 communicating the inside of container 18 with the cavity of said rigid'body member.
  • a delivery cap 19 is mounted on the free end of said tubular element 13 and provided with outlet nozzles, the cap being capable of oscillating relative to the valve bottom.
  • Said machine end 20 operates on the tubular element 13, downward urging it until the lower end of finger rests on the second shutter 8, the latter being forced on the bottom wall 5 of the rigid valve body member and closing said hole 15, that is shutting off the communication between the deformable bag 18 and the'internal cavity of the rigid body member.
  • a pressure gas is supplied from themachine, the lower end 20 of which is schematically shown in FIG. 3, this pressure gas passing through the cavity of tubular element 13, the space between said ribs 12 and entering the cavity of said rigid valve body member, the pressure gas passing therefrom directly into the container 2 through hole 14, after causing the resilient container inlet 17 to be lifted off of said hole.
  • shutter 8 is held pressed on the bottom wall 5, keeping hole closed, also because of the gas pressure entering the cavity of body 4, as above described.
  • the gas pressure in the cavity of body 4 as the propelling gas is supplied to the container is higher than the pressure said gas has within the container and higher as well than the pressure existing within said bag 18, since said propelling gas undergoes load losses on passing through hole 14 and on being diffused through the space between the outer surface of wall 4 and the adjacent surface of the deformable bag inlet 17.
  • valve allows for introducing the propelling gas into the container 2, after said valve has been steadily and definitely mounted onto the container, and that any risk is avoided that the propelling gas may also enter the deformable bag 18.
  • the propelling gas can be totally at a gaseous state or partially at a liquid state, in which case there will be on the container bottom an amount 21 of liquified gaswhich would act as a reserve and would evaporate during the container use to make up for the decrease in volume of the deformablebag as a result of the delivery of liquid therein contained.
  • liquified gas which would act as a reserve and would evaporate during the container use to make up for the decrease in volume of the deformablebag as a result of the delivery of liquid therein contained.
  • the finger 10 of the first shutter operates on the second shutter 8, causing it to oscillate sidewise and at least partly lifting it off of the bottom wall 5 of the rigid body member, thus opening said hole 15 and enabling the liquid in the deformable bag, as compressed by the propelling gas entrained in the container 2, to exit through said hole 15, enter the cavity defined by walls 4 and 5 of the valve body and exit through the cavity of the tubular element 13 and then through the nozzles in the delivering cap after passing through the passage defined between the tubular element 13 and the first shutter 7, at said radial ribs 12, since the upper free edge of the first shutter would be no longer kept pressed on the entire periphery against seal 6.
  • the structure of the valve is very simple and its operation is reliable and, particularly, that the liquid in bag 18 cannot be mixed with the propelling gas either when the container is being pressurized, or during delivery step.
  • FIGS. 4, 5 and 6 an embodiment of the valve different from that in FIGS. l-3 is shown therein.
  • the same reference numerals have been used as those in the preceding figures to designate the same structural components, the container not having been shown in FIGS. 5 and 6, whereas on the free end of the tubular element 13 outwardly of the container neither the delivering cap, nor the lower end of the machine for introducing the pressure gas into the container have been shown.
  • FIGS. 4, 5 and 6 differs from that in FIGS. 1-3 essentially in that the tubular element 13 is fast with a shutter 22, similar to the above described shutter 7, and at its lower end having an elongated spoke 23 with a larger cross-section than that of the hole 15 in the bottom wall of the rigid valve body member.
