Definitions

  • the present invention relates to a valve for equipping a pressurized container.
  • Such valves are used in particular in the field of cosmetics for the distribution of hair products (lacquers, styling sprays, etc.) of personal care products, make-up products, or products protecting against the harmful effects. of the sun.
  • valves in a most common configuration, comprise a valve body within which is mounted an opening / closing member in the form of a valve stem, a portion of which emerges outside the valve body .
  • the valve stem is able to slide sealingly into engagement with a sealing member in the form of an annular seal.
  • valve stem is traversed by an axial channel, one end of which opens axially outside the valve body, and is intended to be placed in communication with a passage passing through an actuating member of the valve comprising at least one orifice of exit.
  • the other end of the channel opens radially via an inlet orifice, or several inlet orifices arranged in the same axial position.
  • the (or) inlet (s) is (are) opposite the sealing element.
  • valve sink In response to an actuation command, the valve sinks axially, and the inlet port (s) of the valve stem is (are) brought into communication with the pressurized product within the valve body.
  • the product is then conveyed, via the valve stem and the passage passing through the actuating member, to the dispensing orifice.
  • these are placed in communication simultaneously with the valve body.
  • valves in addition to actuating in response to axial movement, may be actuated in response to a force exerted laterally to the valve stem. Such valves are called "tilting".
  • the opening / closing element does not emerge outside the valve body.
  • a portion of the actuating member is engaged within the valve body, and controls the opening or closing of the valve.
  • valve in a different configuration is described for example in the patent FR 2,725,182.
  • the valve body is crossed by a purge port for the distribution, together with the product, or separate, propellant.
  • the actuation control causes a movement of the opening / closing element, and its passage from a closed position to an open position in which the product is dispensed at a determined rate and unique.
  • the first type of valve it is the section of the inlet orifice (s), and / or their number, which determines the output flow rate.
  • a valve of the type described in FR 2,725,182, mentioned above it is the depth and / or the width, and / or the number of grooves formed on the inner surface of the valve body.
  • a container equipped with a valve allowing a first flow is used.
  • a container equipped with a valve for a second flow greater than the first.
  • Variable flow valves are described in US-A-3,292,827, US-A-3,195,569 and US-B-6,296,155. By their configuration, the two positions with different rates are very close to each other. In particular, the two flows are obtained by transmitting to the valve stem a force in the same direction, more precisely by more or less significant depression of the valve stem.
  • US 4,139,128 discloses a variable flow tilt valve.
  • This valve comprises a valve stem through which a channel opens, on the one hand, on an outlet port of the product and, on the other hand, on an inlet passage of the product delimited between two parts of the valve stem.
  • this passage is communicated with the pressurized product within the valve body.
  • the valve stem is tilted, the two parts of the valve stem that delimit the product inlet passage apart from each other so as to enlarge the passage. Again, the two flows obtained are not clearly distinct.
  • valve capable of dispensing a product at different flow rates, depending on the desired spray characteristics, clearly distinguishing the actuating movements to distribute the product according to different flows.
  • a tilt type valve for dispensing a product contained in a pressurized container, said valve having a longitudinal axis X and comprising a single opening / closing member provided with at least two inlet ports, the opening / closing element being adapted, in response to a force transmitted to the opening / closing element laterally to the X axis, to move from a closed position at a first open position in which the pressurized product is dispensed at a first rate, and which, in response to a force transmitted to the opening / closing element parallel to the X axis, is able to move from the closed position to a second open position in which the product is dispensed at a second rate, different from the first.
  • the two open positions are positions each authorizing a different delivery rate, each of which can be obtained under normal conditions of use by manual actuation, particularly with the finger, and can be maintained as long as desired.
  • the product in a first open position, is distributed in a relatively low flow, in the form of a lacquer. In a second open position, the product is distributed at a higher rate in the form of a spray.
  • the same device can then be used for both distribution modes.
  • the movement to actuate the opening / closing element to dispense the product at a first rate is relatively different from that for dispensing the product at the second rate.
  • the force transmitted to the opening / closing element is the force exerted by the user directly on the opening / closing element.
  • the first rate is obtained by flipping the opening / closing element while the second rate is obtained by depressing it, which allows the user to easily differentiate the two rates.
  • the opening / closing element is surmounted by an actuating member, for example a push-button
  • the force transmitted to the opening / closing element is that transmitted by the push button in response to the force exerted by the user on the push button.
  • the two flows can also be easily identified by identifying for example two distinct surfaces on the push-button, a first surface for transmitting to the opening / closing element a force laterally to the X axis, and a second surface allowing to transmit to the opening / closing element a force parallel to the axis X.
  • the valve may be in communication with the product via a dip tube, the product then being propelled by means of a liquefied or compressed gas.
  • the product is contained inside a pocket with flexible walls, outside of which is the propellant gas.
  • the opening / closing element may consist of a valve stem, a portion of which emerges outside a valve body, said valve stem being traversed by a axial channel opening, on the one hand, outside the valve body via an outlet orifice and, on the other hand, via at least two inlet ports which, in the closed position, are isolated from the valve body .
  • the valve may comprise a sealing element, in particular in the form of an annular seal, disposed inside said valve body, and the valve stem may comprise an annular portion disposed inside the valve body, said annular portion being provided with a lip adapted, in the closed position, to bear against the sealing element so as to define, with said sealing element, an annular space isolated from the valve body, a first orifice entrance opening into the annular space.
  • a sealing element in particular in the form of an annular seal
  • the valve stem may comprise an annular portion disposed inside the valve body, said annular portion being provided with a lip adapted, in the closed position, to bear against the sealing element so as to define, with said sealing element, an annular space isolated from the valve body, a first orifice entrance opening into the annular space.
  • At least a second inlet orifice opens laterally opposite said sealing member, in the closed position.
  • the first and second inlet ports may be of identical sections, or of different sections.
  • the flow rate is not necessarily a direct function of the number and size of the orifices. Indeed, in the case where the product enters the valve stem via at least two separate orifices, the product flows via the different orifices may, depending on the relative position of the orifices, interfere with each other, so that the resulting flow may be different from the sum of the flow rates specific to each orifice, taken independently.
  • the first and second inlet ports may be at different angular positions. This configuration makes it possible to reduce the transient phenomena between the flow rates corresponding to each of the opening positions.
  • a device for packaging and dispensing a product, in particular a cosmetic product, the device comprising a pressurized container containing the product to be dispensed, and equipped with a valve according to the present invention.
  • the product can be pressurized with compressed or liquefied gas.
  • the propellant may be in contact with the product or separated from the latter by a piston or a flexible bag inside which is disposed the product.
  • the device may further comprise a member for actuating the valve and dispensing the pressurized product via at least one dispensing orifice situated for example inside a nozzle, in particular a swirling nozzle.
  • the actuating member may comprise two separate bearing surfaces for actuating the valve, a first bearing surface for axially moving the opening / closing element and a second bearing surface for moving laterally the opening / closing element.
  • the first bearing surface may for example be a surface passing in a plane substantially perpendicular to the axis X.
  • the second bearing surface may for example pass in a plane parallel to the axis X or a surface passing through a plane substantially perpendicular to the X axis formed at a distance from the X axis and which does not contain it.
  • the device according to the invention can advantageously be used for packaging and dispensing under pressure a cosmetic product, in particular a hair product, a personal care product, a make-up product, a cosmetic product or a cosmetic product. skin care product or a protective product against the harmful effects of the sun.
  • the device 100 shown as a whole in FIG. 1 comprises a cylindrical container 20, in particular made of aluminum or tinplate, and surmounted by a head 30 for the actuation of a valve 10 (which will be described in detail later) and for the distribution of a composition, in particular capillary, through a dispensing orifice 31.
