Definitions
- the present invention relates to a valve housed in the outlet end of an airless distribution system also called “airless”, that is to say without air intake, assembled on a container in which is conditioned a fluid product.
- Said tip comprises an outlet channel opening on an outlet orifice, the valve closing the outlet orifice when the dispensing system does not deliver the packaged product into the container.
- the tip equipped with such a valve is commonly referred to as the shutter tip.
- the airless distribution systems are designed to prevent the product packaged in the container from coming into contact with the air before it is dispensed. They are used to dispense fluid, liquid or pasty products that must not be in contact with air before their use, for example -excluding- pharmaceutical or cosmetic products.
- These dispensing systems are generally equipped with a non-return pump to ensure the dosage and allow the evacuation of the packaged product in the container.
- the packaged product circulates from the container to the pump, then from the pump to the discharge port under the effect of the movement printed to the pump by means of a push button,
- the pump is normally equipped with an inlet valve and an outlet valve to allow its operation. At rest, when the dispenser is not used, said valves are closed. The packaged product is therefore not in contact with air from the container to the pump outlet valve.
- the object of the invention is to provide a shutter tip equipped with a valve much simpler and therefore much more reliable and cheap than a shutter valve movable, while having a barrier property "l ' air as effective as the barrier provided by said movable shutter valves.
- the valve of the invention also offers excellent directional control of the outlet jet of the packaged product.
- the valve according to the invention consists of a rigid endpiece having in its center a shaft of axis xx 'and a valve. Said valve is characterized in that:
- said valve is monobloc and has a flexible wall located opposite a free end of the rod, the flexible wall is perforated with a concentric orifice with the end of the rod,
- the orifice has a contour substantially homothetic to that of the contour of the end of the rod in a plane P perpendicular to the axis xx 'of the rod, the orifice has a surface smaller than a projected area of the end of the rod in the plane P,
- valve is in the closed position when the flexible wall is in contact with the end of the rod, on the entire perimeter of the orifice and in the open position when the flexible wall is distant from the end of the rod on at least part of the perimeter of the orifice,
- valve and the stem constitute a sealed assembly when the flexible wall is in contact with the end of the rod over the entire perimeter of the orifice
- valve is connected to the end piece by a non-deformable fixed connection
- valve moves from the closed position to the open position by deformation of the flexible wall
- the flexible wall bears on the end of the rod at any point on its surface in contact with the said end
- said support is obtained by elastic deformation of said flexible wall, said deformation resulting from the assembly of the valve and the nozzle and,
- the flexible wall is part of a cone of substantially flattened convex revolution, coaxial with the axis xx ', the angle of the wall with the axis xx' being between 90 ° and 135 °, preferably between 90 ° and 90 °; ° and 120 ° when said flexible wall is supported on the end of the rod.
- the axis xx ' is directed in the direction of flow of the product from the inside of the nozzle to the outside.
- the angle of the wall is measured as illustrated in Figure 3. When said angle is between 90 ° and 135 ° as shown in Figure 3 the flexible wall has a convex conical shape.
- the rigid wall can be indifferently directed towards the inside or the outside of the cavity.
- the valve according to the invention therefore comprises a valve housed in the cavity that constitutes the outlet channel when it opens on the outlet orifice of the dispensing system.
- valve the assembly combining the outlet tip of said dispensing system and the valve housed in said nozzle to make a mouthpiece said shutter.
- the valve is thus sealed in the rest position.
- the elastic deformation of the valve is that it is in support that is to say in prestressed support on the rigid wall of the rod.
- the opening and closing of the passage of the product are obtained by the complementary deformation and thus the displacement of the flexible wall in the axis xx 'under the effect of the pressure of the product resulting from the setting in motion of the pump.
- the rod is disposed inside - substantially in its center - of a cavity pierced with a first opening, the free end of the rod being disposed at the center of said first opening, the first opening being part of a plane substantially perpendicular to the axis xx '.
- the product can thus flow outside, the cavity and said first opening constituting the end of the outlet channel and the outlet of the dispensing system of the product.
- the valve is equipped with a chimney, of which a first end is connected to a peripheral zone of the flexible wall, said valve is fixed on the endpiece by fitting of the chimney in the cavity along the axis xx ', a outer face of the chimney and an inner face of the wall of the cavity describe a substantially annular shape of revolution cooperating with each other, said outer face being in sealing engagement on the inner face of the wall of the cavity, the rod being disposed inside the chimney after assembly, the rod and the chimney being then substantially coaxial and concentric.
- the valve is thus simply mounted on the tip by eon fitting into the cavity.
- the valve forms a one-piece assembly, the valve consisting of an elastic polymer shape memory.
- the valve is fixed and monobloc decreases the number of parts, the connection between the valve and the nozzle being made without additional assembly part.
- the valve being made of elastic polymer shape memory, the deformation of its flexible wall during the fitting creates a pressure thereof on the rigid wall of the rod and allows not only to ensure sealing at rest Also, its automatic return to the support position after evacuation to the outside of the dosed product in the pump.
- the tip forms a one-piece assembly.
- the tip thus consists of the rod and the cavity located at the end of the discharge channel, the opening of the cavity constituting the outlet of the product.
- the flexible wall is flat when it bears on the end of the rod.
- the flexible wall may be substantially flat and substantially perpendicular to the axis xx 'without departing from the scope of the invention.
- the flexible wall will have a cone shape whose generator has an angle less than 90 ° with the axis xx 'before assembly (cone entering the inside of the tip). The deformation resulting from the assembly and the bearing on the end of the rod gives the wall a convex cone shape more or less flattened.
- the orifice and the projection of the end of the rod in the plane P are circular in shape.
- This arrangement ensures a more homogeneous passage at any point of the perimeter of the orifice when the valve is in the open position.
- a traditional lip shutter consists of two lips resting on one another in a jaw shape.
- the shutter according to the invention consists of a flexible perforated wall of an orifice, preferably circular and central, held in abutment on a rigid wall on its perimeter area around the orifice.
- This arrangement provides control and perfect consistency of the support of said flexible wall at any point of said perimeter area on the rigid wall.
- This provides a perfect seal, equivalent to that obtained by means of a complex and fragile sealing system equipped with movable valves.
- the system is optimized if the orifice is circular and the end of the rod shaped circular cap.
- the wall of the valve is convex conical when it bears on the end of the rod, that is to say present with the axis xx 'an angle of between 90 ° and 135 ° ° as shown in Figure 3.
- the complementary deformation of the flexible wall in the axis xx 'under the effect of the pressure of the conditioned liquid is an elastic strain of elongation type in the vicinity of the orifice, which induces an important restoring force which guarantees the sealing of the valve in the rest position after evacuation of the dispensed liquid.
- the modularity of the opening angle of between 90 ° and 135 ° makes it possible to optimize the closing force of the valve as a function of the elasticity of a previously determined polymer.
- the orifice and the projection of the end of the rod in the plane P are of circular shape, other shapes are possible for the orifice, for example a shape of ellipse more or less flattened if the Industrial wants a jet of product of more or less flattened form. It will then be necessary to adapt the profile of the rod near its end to the shape of the orifice so as to preserve a substantially constant support of the flexible wall at any point of the perimeter area around the orifice.
- the invention also relates to an airless distribution system with pump comprising a valve with at least one of the preceding characteristics providing the shutter tip function and integrated into the push button of said system, the product to be broadcast being brought by a channel housed in the push button and opening into the cavity and escaping through the orifice through a passage.
- the tip and the push button may constitute a one-piece assembly, this mistletoe contributes to further simplify the device and "reduce the cost of manufacture.
- the airless delivery system with pump comprises a valve having at least one of the preceding characteristics and simultaneously providing the valve outlet valve function and shutter tip. This possibility stems from the high quality of the airtightness of said valve and makes it possible to further reduce the manufacturing cost of the dispensing system.
- the invention also relates to an airless flexible tube device having an orifice, characterized in that it comprises a valve with at least one of the preceding characteristics, said valve being housed in the orifice and constituting a shutter tip said flexible tube.
- the flexible tube is another type of container whose volume is likely to correspond at any time of its use to the residual volume of the product it contains.
- the orifice of the tube is open. When the user releases the pressure on the wall of the tube, the air enters the tube as a total or partial substitution of the evacuated cream. In use, there is therefore a large amount of air in the tube, especially when the tube wall has a large memory shape, which is often the case for the tubes used to package care creams.
- the orifice of the flexible tube is equipped with a valve forming a shutter tip.
- the pressure created in the tube opens the valve and releases the passage of the tube orifice, as soon as it interrupts this pressure, the valve closes preventing the penetration of the tube. air in the tube.
- This application of the invention is therefore of great interest insofar as it makes it possible to have a packaging without air, without the use of a pump, which is more expensive than the device, and whose ergonomics are moreover poorly adapted to the association with a flexible tube type container.
- the endpiece also supports a second flexible valve fitted in the rod and resting on a face opposite the first opening, said second valve constituting with the tip an additional anti-return valve.
- the flexible tube thus has two barriers to the air inlet into the container, the two barriers being arranged "in series" with respect to each other.
