Definitions
- the present invention relates to a fluid dispenser comprising a reservoir intended to contain fluid and defining a wall which is pressed to decrease the volume of the tank.
- the dispenser includes a dispensing orifice through which the fluid is dispensed each time the tank wall is actuated.
- distributors of this type already exist in the prior art. They are especially used in pharmacy, cosmetics and perfumery. We find some also in the form of a free sample for advertising purposes containing small doses of fluid.
- the distributor then takes the form of a simple packaging formed by a flexible reservoir with a dispensing orifice. The user grasps the packaging between the thumb and forefinger and presses the flexible walls of the reservoir to let fluid flow out through the orifice of distribution.
- this type of distributor often does not have good quality.
- dispensing in particular spraying, in the case of liquid product like perfume. This is explained by the fact that the spraying is directly dependent on the force with which the user presses on the walls of the tank flexible. If the user presses slowly, the spraying will not be good and the fluid will tend to drip and not be sprayed.
- the distributor described in document FR-2 778 639 recommends giving the actuating wall a predetermined threshold of resistance to deformation that must be overcome to deform it. Wall actuation does not deform immediately upon user pressure. The user will have to press hard enough to overcome the resistance threshold. The depression of the actuating wall is then rapid and brutal, which ensures immediate pressurization of the product stored in the tank of the distributor. The product is then distributed with good spray quality.
- the object of the present invention is to define another distributor of this type, i.e. with a tank with a deformable wall, where the product stored in the tank is distributed in a perfectly proportioned manner with good quality of spray.
- Document US Pat. No. 4,795,063 describes a dispenser comprising a reservoir flexible formed of two sheets welded together on their periphery.
- the reservoir contains a pump consisting of a base forming a piston and a body in which the piston of the base slides.
- the base also forms an inlet valve while the body forms an outlet valve.
- the body also forms a welding collar on which an opening formed by one of the sheets is welded.
- the base and the body are moved away from each other by a spring. By bringing the base towards the body against the force exerted by the spring, the volume of the pump chamber decreases and the product fluid is discharged through the outlet valve which constitutes the dispensing orifice.
- the base of the base can be likened to a pusher, and this base is located below of a deformable wall of the reservoir. Therefore, the base of the base can be moved by pressing on the deformable wall of the tank.
- the repressed fluid product by the pump leaves the distributor at the outlet valve which is located in the axis of movement of the base. Care must therefore be taken when actuating this distributor, not to obstruct the outlet valve with a finger, since the ideal position of the finger serving as a reaction to the thrust exerted on the base is that of the outlet valve. Therefore, the fingers should be positioned next the outlet valve, so that the dispensed product can come into contact with the fingers, which is not the goal. It is therefore not at all easy to use such a distributor. This is due to the fact that the dispensing orifice is formed by the valve outlet valve and that this outlet valve is located at, or opposite to, the deformable wall of the tank.
- the object of the present invention is to remedy the drawbacks of this art prior.
- the present invention provides a fluid dispenser comprising a reservoir intended to contain fluid product and defining a actuating wall, and a dispensing orifice through which the fluid product is distributed on each actuation of the tank wall, the tank containing in addition to a pump defining a pump chamber provided with an inlet valve to communicate with the tank and an outlet valve, the pump comprising a pusher which is pressed to decrease the volume of the pump chamber, said pusher being disposed below the actuating wall of the reservoir, a discharge pipe connecting the outlet valve of the pump to the orifice of distribution, characterized in that the pump plunger is formed by a wall deformable from the pump chamber.
- a principle of the present invention lies in the fact of fully integrating a pump inside a conventional container wall packaging deformable.
- the integration of a pump inside such packaging has still other advantages: for example, the actuating wall of the tank does not need to have a shape memory, since its return to the state initial is ensured by the return force of the pump which tends to bring back the pusher in the rest position.
- the actuating wall of the reservoir can thus have a constant shape in rest position whatever the filling state of the tank.
- the pump inside the tank ensures a certain resistance to this so that the user has an easier time entering it.
- the pump is mounted on a piece of support defining the dispensing orifice.
- the conduit of backflow is formed by the support piece.
- the reservoir is fixed to the support part.
- the reservoir is formed from two sheets deformable welded together on their peripheries. This is a conception quite classic for a distributor serving as a free advertising sample.
- deformable sheet is meant both film complexes and thermoformed shells or a combination thereof.
- the support part comprises an attachment appendage on which the tank sheets are fixed, preferably by welding. So, the fixing appendage closes the tank.
- the support piece forms a housing in which component parts of the pump are inserted.
- the support piece defines a valve seat for the valve. pump inlet.
- the support piece is therefore part of the pump, since it cannot function without it.
- the fluid dispenser according to the invention comprises a reservoir 1 containing fluid.
- This reservoir 1 is formed with an actuating wall deformable 14 which can be pressed to deform the tank and thus reduce its volume.
- the reservoir may be in the form of a flexible pocket produced from one or more sheets of complex films.
- the tank can be made from a sheet of complex film folded back on itself and welded on its periphery.
- the tank can also be made from of two sheets of complex films welded together on their peripheries.
- the tank can be formed from a shell of advantageously thermoformed plastic material on which a film has been welded sealing to thus form the reservoir 1.
- the tank in the form of a tube flexible type of toothpaste which is welded at one end and which is provided with its other end of a dispensing orifice.
- the material of the tank as well as its shape therefore matters little, provided that one of these walls is deformable by so as to reduce the internal volume of the tank.
- the tank is in the form of a welded deformable sheet or shell on its periphery to another sheet or another deformable shell.
- Wall actuation 14 is carried out at the level of the sheet or shell 11.
- the two sheets or shells are welded together over their entire peripheries 10 except on the side where a dispensing orifice 20 is formed.
- the dispensing orifice 20 is formed by a support piece 2 which extends from the dispensing orifice 20 towards the inside of the tank 1.
- This support piece 2 forms an appendage of attachment 23, which is here a welding appendage on which the sheets or shells 11 or 12 are welded.
- this appendix of welding 23 is in the form of a diamond or an eye, which facilitates the welding of sheets or shells 11 and 12 on the appendix, as well as together at level of the commissures of the eye formed by the appendix 23.
- the appendix of welding 23 closes the reservoir 1 by forming the dispensing orifice 20 as is can see it in figure 3.
- the dispensing orifice is formed at one end of a nozzle which extends towards the inside of the tank beyond the appendage of welding 23 and which internally defines a discharge conduit 21.
- the support part 2 supports a pump 3. More specifically, the support piece 2 forms a housing 24 in which the the pump 3 are mounted, for example, by force. On the other hand, the support piece 2 forms an inlet channel 22 which is separated from the discharge conduit 21 by a stud 25.
- the support piece certainly supports part of the pump, but does also an integral part of the pump by defining the inlet channel 22 and the discharge pipe 21.
- the pump 3 defines a pump chamber 31 provided with an inlet valve 32 which communicates the pump chamber 31 with the reservoir 1 through the channel inlet 22.
- the pump chamber 31 is also provided with an outlet valve. 33 which communicates the chamber 31 with the dispensing orifice 20 through the discharge channel 21.
- the inlet valve 32 opens when a vacuum is created in the pump chamber 31, and closes when the product inside the chamber 31 is pressurized.
- the outlet valve 33 opens when the product in the pump chamber is pressurized and closes when a depression is created inside the pump chamber.
- the pump is also provided with a pusher 34 which makes it possible to make decrease the volume of the pump chamber 31 and thus put the fluid product content inside under pressure.
- the plunger 34 of the pump 3 is arranged below the actuating wall 14 of the reservoir 1. Consequently, when the pressure is pressed actuating wall 14, the push-button 34 is also pressed, which has the effect activate pump 3.
- the pump is completely invisible since completely contained inside the tank 1. A metered amount fluid product is thus distributed with a good quality of distribution.
- the pump 3 secured to its support piece 2 ensures the dispenser is held and also gives the actuating wall 14 the restoring force necessary to return the wall 14 to its initial position. Indeed, the actuating wall 14 takes advantage of the return force of the pusher 34.
- the pump 3 is a deformable diaphragm pump.
- the pusher 34 is formed by a wall deformable of the pump chamber 31.
- the deformable wall 34 is formed by a dome-shaped part 38, the upper part of which is formed by the wall 34 and whose substantially cylindrical peripheral part 36 is engaged inside the housing 24 formed by the support piece 2.
- the pump includes a plate 37 pierced with two through holes 372 and 373 which are located in line with valves 32 and 33. Part of the plate 37 serves as a valve seat for the outlet valve 33.
- the pump 3 comprises a membrane 35 which forms the two movable valves 32 and 33.
- This membrane 35 can appear in the form of a disc from which two small have been cut discs which however remain attached to the rest of the membrane. These two little ones discs form the two valves 32 and 33 capable of pivoting along the segment which connects them to the rest of the membrane.
- the membrane 35 is supported at the bottom of the housing 24 which forms a flange 27 which defines the valve seat for the valve input 25.
- the membrane is supported on the pad 25.
- the support part constitutes a pump member, or more precisely, the part of the support piece forming the housing 24 is part of the pump. The fact that the support piece further defines the appendage of fixing and / or outlet is only an advantageous embodiment.
- the pump formed by its dome 38, its plate 37, its membrane and its housing 24, could be fixed to a support piece which defines the outlet orifice and / or the attachment appendix.
- the fact of housing in one piece with the support piece is only an advantageous embodiment.
- the pump 3 represented in FIG. 2 is particularly simple in design, since it comprises only four constituent organs, know the dome 38, the plate 37 and the membrane 35 and the support piece, which are organs very easy to manufacture; this results in a particularly good pump market.
- the support piece 2, which can for example be made in one piece molded plastic, is very simple to manufacture and therefore inexpensive. he It is therefore possible to manufacture a dispenser serving as a free sample.
