Definitions

  • the invention relates to a valve for a pressurized container, or aerosol can, of the type which includes a valve body intended to be fixed in a cup mounted on the can, a valve stem movable axially in the valve body, and elastic return means for returning the valve stem to a closed position, while the opening of the valve is obtained by a driving action on the stem, said valve being combined with a valve sensitive to the action gravity capable of closing the outlet of the valve when the container occupies a position away, beyond a predetermined limit, from its normal position of use.
  • the container is intended to be used either upside down, or upside down, with its substantially vertical axis.
  • the aforementioned valve intervenes to close the outlet of the valve if the axis of the container is too far from the vertical and / or if the head of the container does not occupy the normal position.
  • FR-A-2 375 111 shows a valve of this type, in particular in FIG. 5 where the valve sensitive to the action of gravity comprises a ball forming a shutter member.
  • the valve sensitive to the action of gravity comprises a ball forming a shutter member.
  • the orifice intended to be closed by the ball of the valve has a relatively reduced diameter creating a significant additional pressure drop, in normal operation.
  • DE-A-1 955 397 relates to a dispensing device according to the preamble of claim 1 which makes it possible to dispense a product contained in a pressure container provided with a dispensing head both upside down and upside down.
  • the valve body of the dispensing head can be closed in the head-down position by a ball, and the wall of the valve body is provided with an opening, an opening which is never closed.
  • the object of the invention is, above all, to make the valve of the kind defined above such that the presence of the valve sensitive to the action of gravity does not introduce any significant additional pressure drop for the flow of the fluid in normal operation. .
  • the invention also aims to provide a valve whose valve reacts to a bad position given to the container. This is particularly advantageous in the case of containers pressurized with the aid of a compressed gas, in particular compressed air, which should be saved to avoid too frequent inflation of the container; in fact, during a bad position given to the container, the spraying is not satisfactory and there is a significant loss of the propellant.
  • the return of the valve to the open position should also be reliable, when the container returns from a bad position to a good position.
  • a valve for a pressurized container, or aerosol can of the kind defined above, is characterized in that the orifice is a micro-orifice which is closed when the rod is pressed so as to prevent any passage of fluid of the container in the valve body through the micro-orifice and which is open when the rod is not pressed to establish a communication between the interior volume under pressure of the container and the zone of the valve situated downstream of the member for closing the valve in the closed position, in order to balance the pressures on either side of this closure member and to facilitate its return to the open position under the action of gravity.
  • the orifice is a micro-orifice which is closed when the rod is pressed so as to prevent any passage of fluid of the container in the valve body through the micro-orifice and which is open when the rod is not pressed to establish a communication between the interior volume under pressure of the container and the zone of the valve situated downstream of the member for closing the valve in the closed position, in order to balance the pressures on either side of this closure member and to facilitate its return to the
  • the force corresponding to the product of the section of the valve seat by the internal pressure of the container can be greater than the weight of the closure member, this force being counterbalanced by an opposite force obtained thanks to the micro-leakage created by the micro -orifice.
  • the closure member When the valve is associated with a dip tube extending from the valve body to the bottom of the container, which is intended to be used with the head at the top, the closure member can be placed in the dip tube which is closed axially at its lower end and is provided with at least one inlet offset radially from the axis of the tube, the seat of the closure member, in particular consisting of a ball, being provided at the end of the valve stem on which the dip tube is engaged.
  • the closure member can be placed in a lower appendage of the valve body.
  • the dip tube can open laterally into this appendage, the seat of the closure member being located at a reduced distance from the bottom of this appendage.
  • the valve In the case of a valve for a container intended to be used upside down, the valve has on its body a lateral extension with a gas inlet in the upper part and a seat in the lower part, the shutter member being able to move in this lateral extension.
  • the micro-orifice is advantageously produced in the form of a notch of reduced dimensions provided on an edge of the valve body intended to come to bear against a sealing washer urged by the valve stem.
  • the valve may comprise a micro-orifice for the passage of gas provided in the valve body and a cap turning its concavity in the opposite direction to the valve body, capable of moving in sliding in this valve body, cap which constitutes the stem of the valve.
  • this cap having at its bottom at least one passage hole and on its periphery two circular sealing rods spaced axially and arranged so that in normal operation, cap pressed, the passage micro-orifice is trapped between the two rods, while in normal position, valve in closed position, the aforesaid micro-orifice establishes a passage between the interior of the valve body and the container.
  • the closure member in particular a ball, is retained in a housing provided in the valve stem.
  • the invention also relates to a pressurized container, or aerosol can, equipped with a valve as defined above.
  • Figure 1 of these drawings shows, schematically in section, a pressurized container and a valve, with dip tube, according to the invention, a detail being shown on a larger scale.
  • Figure 2 shows, on a smaller scale, the container of Figure 1 upside down, that is to say in the wrong position, its operation being made impossible.
  • FIG. 3 illustrates an alternative embodiment of the valve with a quick-closing system.
  • Figure 4 is another variant of the rapid shutter system.
  • Figures 5 to 7 show, respectively head up, head down, and return to the head up position, a valve according to another alternative embodiment.
  • FIG. 8 illustrates a valve according to the invention intended for head-down operation, and which is in the blocking position according to this FIG. 8.
  • FIG. 9 finally, illustrates the valve of Figure 8 in its normal operating position upside down.
  • a pressurized container of the aerosol can 1 type containing a liquid 2 to be sprayed and a propellant 3 preferably consisting of an inert gas, in particular air, compressed or else still a propellant or a mixture of liquefied gases.
  • a propellant 3 preferably consisting of an inert gas, in particular air, compressed or else still a propellant or a mixture of liquefied gases.
  • the container 1 has an opening 4 on which a cup 5 is crimped.
  • a dispensing valve 6 is fixed, generally by crimping, to the center of the cup 5.
  • the valve 6 comprises a valve body 7 provided, at its end fixed on the cup, a peripheral bulge 8 or valve shell.
  • the edge of this bulge 8, remote from the bottom of the container 1, is provided with a peripheral rib 9 of triangular cross section, determining an edge against which a sealing washer 10 is pressed, for example made of elastomeric material.
  • the crimping of the central part of the cup 5 on the bulge 8 keeps the outer edge of the washer 10 tight against the edge of the rib 9 so as to provide a seal at this level.
  • communication remains between the interior of the container 1 and the annular zone comprised between the cylindrical external surface of the bulge 1 and the internal surface of the zone adjacent to the cup 5.
  • valve body 7 At its end opposite to the rib 9, the valve body 7 is extended by a tube 11, of reduced diameter, forming a valve stem.
  • a valve stem 12 is mounted axially movable in the body 7, this stem being extended by a portion 13 of smaller diameter projecting outside.
  • An axial channel 14 is provided in part 13 and opens at the free front end. This channel 14 communicates, at its other end, with a radial channel 15 opening laterally into a peripheral groove 16 provided at the junction of the extension 13 and the part of larger diameter of the rod 12 located in the body 7.
  • the edge 17 of the central hole of the washer 10 has a diameter slightly less than the diameter of the groove 16 and squeezes the bottom of the groove by forming, when the rod 12 is not pressed, a sort of lip curved towards the outside so as to ensure the sealed closure of the inlet of the channel 15, with respect to the interior volume of the body 7.
  • the rod 12 is held in the rest or closed position, represented in FIG. 1, by a return spring 18 provided between a shoulder of the body 7 and the rod 12.
  • a sufficient radial space is provided between the external surface of the rod 12 and the internal surface of the body 11 to allow free passage of the fluids.
  • valve 6 The user can cause the valve 6 to open by acting on a push button (not shown), provided with a spray nozzle communicating with the channel 14, so as to push the rod 12 against the force of the spring 18.
  • a push button (not shown), provided with a spray nozzle communicating with the channel 14, so as to push the rod 12 against the force of the spring 18.
  • This action makes it possible to put the radial channel 15 into communication with the internal volume of the body 7, the sealing washer 10 deforming at its internal edge to allow this communication while maintaining a seal around the base of extension 13, facing the outside.
  • the container 1 shown in FIG. 1 is intended to be used head up and a dip tube 19 is engaged around the tube 11, this tube extending to the bottom of the container.
  • the valve 12 is combined with a valve C sensitive to the action of gravity and capable of closing the outlet of the valve when the container 1 occupies, as illustrated in FIG. 2, a position, upside down, which is not not the normal position of use.
  • the valve C comprises a seat 20 formed by the end of the tube 11 remote from the body 7 and a shutter member constituted by a ball 21, movable under the action of gravity, and adapted to be applied in leaktight manner against the seat 20, so as to close the tubing 11 and prevent any product from escaping through the valve stem 12.
  • the ball 21 is placed in the dip tube 19 which is closed axially at its lower end by a bottom 22.
  • the tube 19 is provided with a lateral inlet 23 provided near the bottom 22.
  • the inlet 23 is provided in the cylindrical wall.
  • one or more inlets 23, for example constituted by holes, could be provided in the bottom 22, in being offset radially with respect to the axis of the tube 19.
  • a micro-orifice F is provided in the wall of the valve body 7 to establish communication between the interior pressurized volume of the container 1 and the zone of the valve located downstream of the ball 21 in the closed position. This micro-orifice is closed by the washer 10 when the valve stem 12 is pressed.
  • the micro-orifice F is constituted by a notch 24 of reduced size, in particular from the angular extended point of view, provided in the edge of the peripheral rib 9.
  • the mean plane of the washer 10 is substantially orthogonal to the axis of the valve, so that a micro-leak is created, by the notch 24, at the below the washer 10 between the interior volume of the container 1 and the interior volume of the valve body 7.
  • the washer 10 deforms, its interior edge being pushed towards the bottom of the body 7 , while its outer edge is maintained by crimping; the inner face of the washer 10 therefore takes a concave shape and closes the notch 24, so as to cut the micro-leak when the rod 12 is pressed and therefore when the valve 6 is open.
  • the ball 21 is applied against the seat 20. If the user pushes the rod 12, the interior space of the body 7 is placed in communication with the atmosphere by the channels 15 and 14. The ball 21 is applied firmly by the pressure prevailing in the container 1 against the seat 20 and opposes any outflow of fluid through the channels 15 and 14. In addition, the micro-orifice formed by the notch 24 is closed when the rod 12 is pressed in such a way so that there is no passage of fluid from the container 1 towards the interior of the body 7 through this micro-orifice.
  • the notch 24 opens again and allows the entry of pressurized gas inside the body 7 so as to balance the pressures on both sides of the ball 21 bearing against the seat 20.
  • the ball 21 leaves its seat 20 to move towards the bottom 22, under the action of gravity. This movement is not prevented by a pressure difference between the inside of the can 1 and the inside of the body 7, thanks to the communication established by the notch 24.
  • the seat 20 can have a large diameter relative to the diameter of the ball 21 as illustrated in Figure 1 of the drawings, which does not prevent the return of the ball 21 in the open position as soon as the container 1 is found head up, with the valve 6 closed.
  • Figure 3 illustrates an alternative embodiment of the container of Figure 1 according to which the ball 21 of the valve C is located in the axial proximity of its seat 120 so that the closure of the valve is faster than in the case of Figure 1 since the path to be taken by the ball 21 is reduced.
  • the tubing 111 in FIG. 3, is closed by a bottom 122 against which the ball 21 rests, when the container is in its normal position.
  • the seat 120 is constituted by a frustoconical shoulder provided axially in the vicinity of the connection of the tube 111 and of the body 7.
  • the dip tube 119 is connected to a lateral oblique nozzle 25 opening into the tube 111 upstream of the seat 120 so that, when the ball 21 is sealingly pressed against the seat 120, the tube 119 no longer communicates with the internal volume of the body 7.
  • the normal position for using the container of FIG. 3 is also head up.
  • the operation is similar to that of FIG. 1, but the shutter is obtained more quickly in the event of the wrong position of the container for spraying.
  • FIG. 4 illustrates another alternative embodiment of a valve according to the invention for aerosol canisters with normal head-up operation.
  • the tubing 211 of reduced axial length is provided with a bottom 222 against which the ball 21 rests when the container occupies its normal position.
  • This bottom 222 is crossed by passages 26 parallel to the axis of the tube 211 but spaced radially from this axis so that their extensions are beyond, in the transverse direction, of the contour of the ball 21 when it is in abutment against the center of the bottom 222.
  • These passages 26 allow the fluid from the container to flow.
  • the dip tube comes to cap axially the pipe 211.
  • a micro-orifice is provided as in the case of Figures 1 and 3 on the flange of the valve body.
  • FIGS 5 to 7 illustrate another alternative embodiment of a valve according to the invention for a container intended to be used head up.
  • FIGS. 5 to 7 identical or similar to elements already described with respect to FIG. 1 are designated either by the same numerical references, or by a numerical reference equal to the sum of the number 300 and the reference used in the figure 1. The description of these elements will not be repeated or will be made only succinctly.
