Definitions
- the invention relates to a simplified metering pump, particularly a pump comprising: [a] a main body with a first surface, [b] first fixing means to a neck of a bottle, [c] second fixing means of a suction tube, [d] an inlet valve, [e] a head, where the head has a second surface facing the first surface and where the first surface and the second surface define a pumping chamber, where The head is made of a material with elastomeric properties capable of being elastically deformed by manual effort and has an external acting surface capable of being deformed by the finger of a user, and [fj an outlet valve at the exit of the Ia pumping chamber, where the outlet valve comprises a valve seat and a moving part suitable for moving between a first position, corresponding to the closed outlet valve and in which the part and mobile is in contact with the valve seat, and a second position, corresponding to the open outlet valve, where the mobile part extends from the head forming a partition, where the mobile part forms a single piece with the head,
- a material with elastomeric properties is any material capable of being subjected to a sufficient elastic deformation to meet the requirements of the invention, in particular, capable of generating a pumping effect of a liquid contained in a bottle.
- elastomeric materials should be included in this group of materials, but also included other plastic materials, such as polypropylene, which, with a suitable geometry, can be subjected to considerable elastic deformation and can regain their initial shape when the external force causing their deformation ceases.
- dosing pumps are known for a plurality of applications. Frequently the dosing pumps are attached to liquid container containers that are for single use only. In this sense, the cost of the dosing pump has to be very tight since it should not greatly affect the total cost of the product. On the other hand, it is common that the dosing pump, apart from having to perform the technical function of pumping the liquid, must have a certain aesthetic appearance, which often imposes important geometric conditions that must be compatible with the correct operation. of the pump. In this sense, there is a permanent need to develop new simplified dosing pumps that allow cost savings and that condition the aesthetic appearance that you wish to give as little as possible.
- the object of the invention is to overcome these drawbacks.
- This purpose is achieved by means of a simplified metering pump of the type indicated at the beginning characterized in that when the moving part is in the first position, and there is a depression in the pumping chamber, then the depression exerts a force that presses the moving part against The valve seat. Indeed, this way the pumping effect is improved.
- the outlet valve does not perform an optimal closure, since when in the pumping chamber there is a depression, thanks to which it is filled with liquid from the reservoir, then the valve The output is closed only thanks to the elastic forces of the head, which is made of a material with elastomeric properties.
- the depression existing in the pumping chamber tends to open the outlet valve, since the outlet valve has, downstream, the atmospheric pressure of the external environment whereby the difference in pressure is against the closure of The outlet valve.
- the moving part is arranged in such a way that the depression existing in the pumping chamber forces the moving part against the valve seat.
- the depression inside the pumping chamber helps the elastic force of the elastomeric head to keep the outlet valve closed, that is, the elastic recovery force and the force due to the depression in the pumping chamber. pumping act in the same direction.
- the moving part of the outlet valve has two faces, one of them oriented upstream (the inner face) and the other oriented downstream (the outer face).
- the moving part when the outlet valve is closed, the moving part has the face that is oriented upstream (the inner face) subjected to the depression inside the pumping chamber, while the face that is oriented downstream ( The external face) is subjected to atmospheric pressure from the outside. Therefore, the pressure difference tends to move the moving part upstream, pressing it against the valve seat. This improves the closure of the outlet valve, which prevents air from entering the pumping chamber and improves the pumping effect of the pump.
- the partition that forms the movable part can have any geometry, whether it is flat, in the form of a cylindrical surface, in the form of a spherical cap, waved, etc. It is only required that the force caused by the difference in pressure (depression inside the pumping chamber and atmospheric pressure at the outlet of the outlet valve) press the partition against the valve seat, which basically consists of a frame on which will support the perimeter of the tabi ⁇ que.
- the partition is a flat surface or a surface cylindrical file Specifically, the cylindrical surface allows it to be better housed in the pump assembly, in which the majority of the surrounding surfaces are also cylindrical.
- a preferred embodiment of the invention is obtained when the partition is a cylindrical surface that extends a certain relatively small angle, generally less than 90 ° and even less than 45 °. In this way, the curved shape of the partition does not stiffen excessively so that it can move by flexion.
- another preferred form of the invention is obtained when the partition is a cylindrical surface that extends 360 °, that is, so that it forms a cylinder that surrounds the second surface.
- the outlet valve communicates the pumping chamber with an annular outlet duct that surrounds the entire pumping chamber.
- the valve seat is formed by a second partition also in the form of a cylinder and is arranged in the main body, such that the second partition surrounds the first surface.
- the partition (which is the moving part of the outlet valve) is supported on the second partition (which is the frame or fixed part of the outlet valve) when the outlet valve is closed.
- the cylindrical septum When compressing the liquid contained in the pumping chamber, the cylindrical septum is completely bent out allowing the liquid to pass to the annular outlet duct.
- the second surface is curved and convex towards the outside of the pumping chamber, and is preferably a spherical cap.
- this geometry optimizes the pumping chamber for a minimum surface area of the head.
- it has a good elastic return force, which causes the external actuation surface to return to its original geometry, overcoming the depression that is generated inside the pumping chamber.
- it is possible to make the second surface flat.
- the external actuation surface of the head does not protrude from its contour, which makes it possible to design pumps that, for example, can be stacked on the head.
- the first surface has a curved and concave area towards the inside of the pumping chamber, and is preferably a spherical zone.
- this geometry optimizes the volume of the pumping chamber with respect to its surface.
- this geometry also adapts in a particularly effective way to the form that the second surface will adopt when deformed by a finger.
- the curved area and the second surface come into contact at the limit of the path followed by the second surface during a pumping movement. In this way, the residual volume of the pumping chamber is minimized, with which the size of the pump can be optimized.
- the curved area to have an outer flange that is convex towards the inside of the pumping chamber.
- This outer flange serves as support for the second surface allowing it to deform in a "softer” way, preventing strong deformations (and, therefore, strong tensions) from forming on the edge of the second surface, that is to say in the junction zone between the part of the head that moves and the part of the head that is attached to the rest of the pump.
- the outer flange serves to further reduce the residual volume of the pumping chamber.
- it also serves to facilitate the return of the second surface to its original position (extended position).
- the support surface between the partition and the frame is increasing, so that the force that tends to close the partition is distributed over a larger surface.
- the moving part has a contact area with the valve seat that has a decreasing thickness as it approaches its free end.
- the head has two parts, the external actuation surface with its corresponding second surface and the movable part of the outlet valve that defines a partition, which make totally different functions.
- the head is a single piece and is made of an elastomeric material, so that the deformation experienced by the head during pumping, which It should be located strictly on the external actuation surface, it can actually affect the moving part of the outlet valve influencing the closing thereof. Therefore, it is advantageous that the pump has at least one column on the first surface that extends to the second surface and is arranged in an area close to the outlet valve.
- the column stops as such that the deformation of the head is stopped by the column and the region of the head in which the moving part of the outlet valve is arranged is not affected.
- the columns Preferably have a height such that they come into contact with the second surface when the second surface is in its extended position. In this way, as soon as the deformation of the external actuation surface starts, the columns exert their support function and the head area in which the moving part of the outlet valve is located does not suffer any deformation due to the deformation of the external actuation surface.
- the pump according to the invention can have a main body that is a single piece comprising first fixing means to the neck of the bottle, second fixing means of a suction tube, and the seat of an inlet valve. This solution minimizes the amount of components of the pump.
- the projection also serves to close the passage of the inlet valve, which also avoids the liquid outflows caused by overpressing the container and / or putting it in an inverted position. This is preferably achieved by making the projection, when the fixing body and the main body are in the closed position, make a tight seal with the second surface.
- the relative displacement is greater than the relative movement.
- the relative displacement is greater than the relative movement.
- the main body comprises a second annular lip that performs a tight seal with an annular partition arranged in the fixing body when the pump is in the closed position, where the annular partition is circling an aeration hole. In this way possible losses of liquid through the aeration orifice are also avoided.

- a simplified dosing pump is shown according to the invention. It comprises a main body 1, a fixing body 3, a head 5 and a ball 7 which is the moving part of an inlet valve 9 arranged in the fixing body 3.
- the main body 1 has a first surface 11 that is cooled ⁇ tatated to a second surface 13 arranged in the head 5. Between them a pumping chamber 17 is defined.
- the head 5 is made of material with elastomeric properties, and has an external actuation surface 15 suitable for being deformed by a user's finger between an extended position, corresponding to the resting position shown in Fig. 1, and a deformed position, corresponding to the end of pumping position shown in Fig. 15.
- the ac surface ⁇ external situation 15 is substantially coincident with the second surface 13, only taking into account that the external actuation surface 15 is that which is physically in contact with the exterior and with the user's finger and the second sup surface 13 is the surface facing the inside of the pump, specifically towards the pumping chamber 17.
- a suction tube 19 is further shown, which is fixed at one end to the fixing body 3 by means of second fixing means formed substantially by a cylindrical projection suitable to accommodate inside the tube 19 aspiration.
- the suction tube 19 has its other end immersed in the liquid to be pumped contained in a bottle, not shown in the Figures.
- the fixing body 3 has first fixing means consisting of a threaded section 21 suitable for being fixed on the neck of a bottle. It also has projections 23 that are housed in helical regattas 25 arranged in the main body 1 so that by subjecting the main body 1 to a rotation with respect to the fixing body 3, apart from the rotation a transfer movement is performed.
- the fixing body 3 has, in addition, a projection in the form of a tubular rod 27 that envelops the inlet valve 9 and extends in the direction of the longitudinal axis and towards the head 5 .
- the tubular rod 27 When the pump is in the closed position the tubular rod 27 is introduced inside the pumping chamber 17 until it touches the head 5, specifically the second surface 13.
- the second surface 13 has a second cylindrical projection 29 that improves the sealing between the second surface 13 and the tubular rod 27.
- the inlet valve 9 is completely closed so that the liquid contained inside the bottle cannot pass through the inlet valve 9 and be poured out although the inside of the bottle is subjected to an overpressure and / or placed in an inverted position.
- the main body 1 has a first annular lip 31 that makes a sealed closure with the outer wall of the tubular rod 27. In this way the pumping chamber 17 is closed without the possibility that the liquid held therein passes inside. of the main body 1.
- the pump has an aeration hole 33 disposed in the fixing body 3 and which allows the entry of air into the bottle to replace the pumped liquid.
- the contact area between the projections 23 and the helical regattas 25 is not airtight, so that the air can pass into the main body 1 and into the bottle through the aeration hole 33.
- the fixing body 3 has an annular partition 35 surrounding the aeration hole 33, and the body main 1 has a second annular lip 37 that makes a closure being with the annular partition 35 when the pump is in its closed position. In this way, the possible flow of liquid from the bottle through the aeration hole 33 is also avoided.
- the partition 41 can be elastically bent so that it performs a movement approximate rotation around the junction zone between the partition 41 and the rest of the head 5 between a first position, corresponding to the closed outlet valve 43, in which the partition 41 is in contact with the valve seat 45, and a second position, corresponding to the open outlet valve 43, in which the partition 41 has been bent arching due to the pressure of the liquid contained inside the pumping chamber 17 (in Figures 6 to 8 it would correspond to a bent to the left).
- partition 41 shown in Figs. 6 to 8 is a cylindrical surface that extends an approximate angle of about 30 °.
- this geometry can be different, such as the partition 41 can be flat, wavy, or any other geometry.
- its perimeter can be substantially rectangular, but it can be with other geometries, such as oval.
- Figure 16 shows another embodiment of a pump according to the invention.
- the partition 41 is a cylinder (that is, a cylindrical surface that extends 360 °) that completely surrounds the second surface 13.
- the partition 41 is in contact with a second partition 47 arranged in the main body 1 and which defines the valve seat 45 of the outlet valve 43.
- the second partition 47 surrounds the first surface 11.
- the pump has two columns 57 that protrude from the first surface 11 and extend until practically touching the second surface 13 when it is in its extended position. Both columns 57 are arranged in an area close to the outlet valve 43. As can be seen in Figure 15, these columns 57 prevent the head 5 from being deformed in the area near the partition 41, that is, in the area close to Ia outlet valve 43. In fact what the columns 57 is to delimit in a clearer way what is the external actuation surface 15 and the second surface 13 of what is the outlet valve 43. Thus, when the external actuation surface 15 has been deformed, as shown in Fig. 15, it is avoided that this deformation extends to the area of the partition 41, which could cause the outlet valve 43 to malfunction.
- the second cylindrical projection 29 of the second surface 13 practically comes into contact with the upper end of the tubular rod 27, when the pump is in the open position and The second surface 13 is in a deformed position.
- a preferred embodiment of the invention is obtained when the relative displacement made by the upper end of the tubular rod 27 when moving between the closed position and the open position is greater than the relative movement made by the second cylindrical projection 29 when moving the second surface 13 between the extended position and the deformed position. In this way it is avoided that, when the pump is in the open position, the second cylindrical projection 29 comes into contact with the upper end of the tubular rod 27 thus reducing the risk of the second cylindrical projection 29 being engaged in the upper end of the tubular rod 27 during a pumping movement.
- the partition 41 is always next to the end of the external actuation surface 15 (which is a spherical cap). However, it is not necessary that this be so, but that, for example, the part of the head 5 and the main body 1 corresponding to the outlet valve 43 could be extended towards the outlet tube so that the partition 41 is more separated from the pumping chamber 17 (for example, halfway between the position in Ia which is in Fig. 1 and the exit hole). This would also reduce the effect of the deformation of the external actuation surface 15 on the partition 41.
