- the pump according to the invention is of the type called "needle”, that is to say having in the upper part a free mounted needle in displacement between a closed position where it closes the end opening of the pump, and prevents product delivery, and an open position where it passes liquid through said end opening.
- pumps which, in a conventional way, comprise a first cylinder forming a pump chamber, which communicates with a gripping tube via a non-return valve, and in which a piston is slidably mounted. hollow. They also comprise a second cylinder, which communicates with the first cylinder, and in which is slidably mounted a second piston constituted by a needle, able to interrupt the communication between the first cylinder and a dispensing nozzle. They finally comprise elastic means, spring-type working in compression, which act on the needle tending to maintain the latter in a closed position where said communication is interrupted.
- these pumps are not designed to allow the pump to decline in several models that can deliver the product with different volumes of volumes. Indeed, we can not change the volume of the chamber without changing the dimensions of the pump. Also, it is necessary to provide packaging specific to each pump size, which leads to significant production costs.
- the invention aims to overcome these disadvantages.
- the pump comprises a needle consisting of a base surmounted by a rod, and a dispensing head movable manually on a pump body, between a rest position and a point of product punctual delivery.
- the head includes:
- a first cylinder forming a metering chamber of the pump, which communicates with a setting tube via a non-return valve, a piston being slidably mounted in the first cylinder;
- the dispensing head comprises means ensuring the passage of the liquid between the metering chamber and a second chamber formed at the end of the dispensing head, without the liquid being in contact with the return means.
- the second cylinder has a compartment in which are housed the elastic return means and is isolated from the second chamber by sealing means, the second chamber communicating with the orifice of the dispensing head.
- the passage means consist of at least one passage channel formed at least partially in a wall of the cylinder, one end of the channel opening into the metering chamber and the other end of the channel opening into the second chamber.
- the pump in such a way that the second chamber has a volume equal to a dose of product.
- This embodiment is however only an alternative embodiment of the invention.
- a pump having a volume smaller than that of a dose may also correspond to the pump according to the invention.
- the second chamber is a chemical or bacteriological treatment chamber of a dose of product.
- the return means consist of a spring working in compression.
- the pump according to the invention comprises means for assembling and centering the return spring with respect to said needle.
- the compartment of the closure means are constituted by a radial ring projecting on an outer wall of a needle base.
- the pump comprises a conduit for checking the seal between the compartment and the second chamber, the duct communicating with the compartment being formed through the wall of the cylinder, and being capable of being connected to pneumatic measuring means.
- it comprises a return spring of the dispensing head in the rest position.
- the dispensing head comprises an inner skirt and an outer skirt, between which the second compression spring is placed, the second cylinder being surrounded by the inner skirt. of the delivery head so that the liquid is not in contact with the second spring.
- the chamber has a volume preferably comprised between 30 and 250 ⁇ l.
- the pump according to the invention comprises support means and attachment to a product container to be dispensed.
- FIG. 1 illustrates, in sectional view, a pump according to a first embodiment of the invention
- the pump according to the invention which will now be described is particularly suitable for use in delivering a liquid or semi-liquid pharmaceutical product in the form of nasal sprays.
- a pump according to the invention could have different shapes, and that it could be applied to other areas than that of the pharmacy.
- the figures that will be discussed in the context of this example will not be limiting.
- a first step the embodiment of a pump 1 according to the invention will be described with reference to FIG. 1.
- a second step reference will be made to FIGS. 2 to 7 to describe the various steps relating to the delivery of a dose of product.
- the pump 1 comprises a needle 2 consisting of a base 21 surmounted by a rod 22, and a dispensing head 4 manually movable on a pump body 10, between a rest position and a position punctual delivery of the product.
- It also comprises means 3 of support and attachment to a product container to be dispensed.
- the head 4 comprises a first cylinder 41 forming a dosing chamber 7 of the pump, which communicates with a gripping tube 42 via a non-return valve 43, a piston 44 being slidably mounted in said first cylinder 41.
- the head 4 also comprises a second cylinder 5 in which the needle 2, forming an exhaust valve, is slidably mounted, as well as elastic return means 6 of the needle 2 in the closed position of an orifice 45 through which the product liquid is expelled.
- the dispensing head 4 comprises means ensuring the passage of the liquid between said metering chamber 7 and a second chamber 8 which is formed at the end of the dispensing head 4, without the liquid being in contact with the return means 6.
- passage means consist of at least one passage channel 46 which is formed at least partially in a wall 53 of the cylinder 5 so that one end of the channel 46 opens into the metering chamber 7 and the other end of the channel opens into the second chamber 8.
- the second cylinder 5 has a compartment 51 in which are housed the elastic return means 6 and which is isolated from the second chamber 8 by sealing means 52, the second chamber 8 communicating with the orifice 45 of the dispensing head 4.
- the volume of the second chamber 8 is smaller than that of the metering chamber 7.
- the second chamber 8 has a volume equal to a dose of product, and comprises means for chemical or bacteriological treatment of said dose, for example by contact with agents dispersed in the wall of said chamber.
- this embodiment has not been illustrated.
- the section ratio between the metering chamber 7 and the second chamber 8 is between 2 and 10. As part of this embodiment (illustrated in Figure 1), the ratio is 8.
- the return means of the needle in its closed position of the orifice 45 consist of a spring 6 working in compression.
- the pump described here comprises means for assembling and centering the return spring 6 with respect to the needle 2.
- centering and assembly means consist of a stud 23 projecting from the base 21, around which the spring 6 engages.
- the sealing means of said compartment 51 are constituted by a radial ring 52 projecting on an outer wall of the base 21 of the needle 2.
- the pump 1 according to the invention which is shown in the appended figures, comprises a duct 55 for checking the tightness between the compartment 51 and the second chamber 8.
- the conduit 55 communicates with the compartment 51 being formed through the wall of the cylinder 5 and being capable of being connected to pneumatic measuring means.
- These pneumatic measuring means may be, for example a manometer, which controls the internal pressure in the compartment 51: if the seal between the compartment 51 and the chamber 8 is not perfect, an air leakage can occur between the ring 52 and the inner face of the wall 53. This air leakage can be revealed through the manometer which then indicates a pressure drop.
- the duct 55 has a dual function since it allows the air contained in the compartment 51 to escape when the spring 6 is compressed, as illustrated in FIG. 4 in particular by an exit arrow S2.
- the dispensing head 4 then comprises an inner skirt 47 and an outer skirt 48 (Figure 1), between which the second spring is placed.
- the second cylinder 5 is surrounded by the inner skirt 47 of the delivery head so that the liquid is not in contact with the second spring 9 which could pollute or contaminate it.
- the sprays of liquid product are usually done in doses whose volumes are between 30 and 250 ⁇ L and it is therefore this volume range that has been chosen for the metering chamber 7.
- the very design of this pump 1 makes it possible to change the volume of the metering chamber without having to modify the packaging or packaging of the bottle provided with this pump.
- Figures 2 to 7 show the pump 1 in sectional view at different times of a spraying of a dose of liquid product, between the moment when a user begins to press the dispensing head 4, and the moment when the head 4 has returned to its rest position.
- FIG. 2 shows the pump 1 in its initial state, before the delivery of a dose of product, and after being primed, that is to say after having been actuated several times to expel the air contained in the chamber dosage, to replace it with a dose of product to be delivered.
- Figure 7 shows the pump 1 in its final state, after the delivery of a dose of product.
- FIG. 3 illustrates the pump 1 at the moment when a user begins to exert a pressure P (illustrated by an arrow in FIG. 3) on the dispensing head 4.
- the compressed product in the metering chamber 7 then exerts itself a pressure on the liquid contained in the passage 46, and indirectly on the liquid product contained in the second chamber 8.
- the pressure exerted on the liquid product contained in the second chamber 8 itself exerts a pressure on the base 21 of the needle 2.
- the base 21 of the needle being secured to the rod 22 of the needle, the latter moves away from the orifice 45 by releasing a passage through which the liquid product is ejected towards the outside of the pump, as indicated by the arrow S1.
- Figure 5 shows the pump 1 with its dispensing head 4 pressed at the maximum of its travel by the user, to its extreme low position.
- the piston 44 is in its highest position in the first cylinder 41, and the metering chamber 7 is penetrated by the end of the piston 44.
- the piston 44 no longer exerts pressure on the liquid contained in the chamber or in the passage 46.
- liquid product contained in the second chamber 8 no longer exerts pressure on the base 21 of the needle 2.
- the spring 6, which works in compression, will relax and remount the needle 2 until the end of the rod 22 comes to close the orifice 45 of the dispensing head 4. The distribution of the dose liquid ends well.
- the spring 9 which works in compression, tends to raise the dispensing head 4 by exerting a thrust at B, between skirts internal of the spray head.
- the dispensing head 4 being integral with the cylinder 41 comprising the metering chamber, drives the cylinder 41 back to its initial position.
- a depression is then created in the metering chamber 7, which then sucks up the liquid product contained in the setting tube 42.
- the dispensing head continues to rise under the action of the spring 9 until reaching its initial high position shown in FIG. 7, and the metering chamber 7 continues to fill under the effect of the depression that is created in the chamber (suction phenomenon).
- the pump 1 can again be actuated by the user to deliver a new dose of product.
- the pump 1 according to the invention is made to limit the expenses related to the packaging and packaging of the bottle on which it is mounted.
