Description

Personal care fluid manual dosing device, personal care fluid dispenser combination and method for dosing a personal care fluid with such a manual dosing device The present invention relates to a personal care fluid manual dosing device, comprising: a housing connectable to a personal care fluid container; a micropump, having a micropump basis including a pump chamber that is stationary connected to the housing and that is provided with a feed opening towards the personal care fluid container, and having a micropump plunger with a micro-pump filling spring that is moveable relative to the micropump chamber and that is provided with a micropump plunger stem incorporating a personal care fluid transit channel leading towards a fluid nozzle; a fluid nozzle tip connecting to the micropump plunger stem, provided with a tensioned closing valve; and a housing cap moveable connecting to the housing, covering the housing and the micropump, provided with a opening leaving through the nozzle side of the micropump plunger stem. The invention also relates to a personal care fluid dispenser combination, comprising such a dosing device that is gas-tight attached to a personal care fluid container as well as to a method for dosing a personal care fluid with such a manual dosing device.
Inthe prior art the outflow of a dispenser may be generated (“driven”) by an overpressure of the fluid to be dispensed, in which case only an outflow opening has to be opened or closed or as an alternative the outflow may be generated by a manual operated (micro)pump that is incorporated in the dispenser, which (micro)pump generates an overpressure (in a pump chamber) as a result of operating the (micro)pump by a user. The present invention is only related to the manual operated dispenser type where a (micro)pump is incorporated in the dispenser and which (micro)pump is driven by a manual operation. In the existing manual operated dispensers the output (outflow) of manual personal care dispensers are often complex of structure and requires pressure to be exerted on opposite sides of the housing cap. The goal of the present invention is to provide an improved personal care fluid manual dosing device, an improved personal care fluid dispenser combination and an improved method for dosing a personal care fluid that enables to dispense a personal care fluid with a single finger operation and independent of the orientation of the manual dosing device / personal care fluid dispenser. To realize that goal the present invention provides a personal care fluid manual dosing device according to claim 1, wherein the housing cap is provided with internal guide surfaces to contact both, the housing, and the fluid container. In an embodiment the internal guide surfaces of the housing cap of the dosing device are located at at least two spaced-apart locations; a first, the housing contacting internal guide surface, at a location closer to the opening leaving through the nozzle side of the micropump plunger stem and a second, the fluid container contacting internal guide surface, at a location further away from the opening leaving through the nozzle side of the micropump plunger stem. In the context of the present invention with “personal care fluid” is referred to all types of fluids like liquids, gels, liquid/gas mixtures, gel/gas mixtures and even mixtures of liquids, gels, gasses with solid particles and so on that are used for body care (e.g. soaps, mousses, gels) but also to (semi-)medicinal products (e.g. ear and eye drops, nasal sprays, ointments) to be administered to a body or body orifice.
Due to the double guidance, preferably at spaced apart positions, the relative orientation of the housing cap to the housing that is connectable to a personal care fluid container is during all relative positions stabilised, independent of the relative positioning of the housing cap and the housing. Thus the use of the dosing device is simplified as a person using the dosing device does not have to pay any attention to the relative orientation of the housing cap as is required in the prior art personal care fluid manual dosing devices where normally forces from two opposite sides must be applied to the housing cap. In practise according to the prior art this is solved by an operation of the housing cover by means of two fingers that thereby engage on opposite sides of the housing cap to ensure evenly distributed forces on the housing cap during operation. The requirement of exerting evenly distributed forces however limits user-friendliness of such a prior art personal care fluid manual dosing device. With the present invention such limitation of the user- friendliness has disappeared. The internal guide surfaces to contact both, the housing, and the fluid container ensure position stability of the housing cap during operation also when operating forces are unevenly distributed over the housing cap, for instance when the housing cap is operated only with a single finger (thus from one side of the housing cap). The present is personal care fluid manual dosing device is not only user-friendly but due to its stability also more reliable. The internal guide surfaces may be embodied as consecutive internal cylindrical guide surfaces. In a specific embodiment the internal guide surfaces may be embodied as a first, the housing contacting internal cylindrical guide surface, at a location closer to the opening leaving through the nozzle side of the micropump plunger stem, and a second, the fluid container contacting, internal cylindrical guide surface, at a location further away from the opening leaving through the nozzle side of the micropump plunger stem, which second internal cylindrical guide surface has a larger diameter than the first internal cylindrical guide surface. Such internal guide surfaces are relatively easy (and thus cheap) to manufacture and do not require special attention during the assembly of the dosing device according to the present invention.
In a further improvement the fluid nozzle tip may be provided with internal flow guides, which internal flow guides may have a curved shape. With such guides the outflow of personal care fluid may be influenced, for instance to provide a rotating spray pattern.
It may also be advantageous to provide the fluid nozzle tip with an external longitudinal profile, for instance embodied as external longitudinal slots. With such an external longitudinal profile an overpressure may be prevented in a body cavity (e.g. ear of nose) during the supply of a personal care fluid to such a body cavity.
For a sideways outflow of a personal care fluid of the fluid nozzle the fluid nozzle tip may protrude transversely from the longitudinal direction of the housing. In this respect “sideways” is to be understood as sideways relative to the container to which the dosing device may be attached, which also implies that the fluid nozzle tip protrudes transversally from the housing cap. Such a dosing device expands the utility and, for specific applications, facilitates the supply of personal care fluid to particular body orifices. In a further embodiment the micropump chamber may be connected to a “diptube” for supply of personal care fluid to the micropump. Such a diptube is to be placed in the personal care fluid container to which the dosing device is attached and enables to supply personal care fluid from a lower location (the bottom) in the personal care fluid container, e.g. by suction.
Yet in another embodiment the fluid nozzle tip connecting to the micropump plunger stem may be provided with a tensioned closing valve. By such a closing valve may prevent pollution to enter the fluid nozzle tip which may, for example, clog it.
The invention also provides a personal care fluid dispenser combination, comprising a dosing device according to the present invention that is gas-tight attached to a personal care fluid container, wherein an internal guide surface of the housing cap of the dosing device is contacting an external surface of the fluid container. The dosing device may be detachable from the personal care fluid container, but as an alternative the fluid dispenser combination may also be offered as a non-detachable combination, dependent whether there is a demand for refillable or, on the contrary, when a personal care fluid is used that should be shielded from external influences.
In an embodiment of the fluid dispenser combination the personal care fluid container may be provided with an internal piston separating a personal care fluid compartment from an air filled compartment that is in open communication with the outside air. This embodiment enables to keep the personal care fluid separate from outside air and may also be helpful to provide the feed of personal care fluid to the micropump independent on the orientation of the fluid dispenser combination , thus further increasing the ease and the possibilities of use.
The personal care fluid container may also be assembled from a bottom part and an upper bottle part, allowing to include an internal piston in the fluid container and/or allowing a bottom filling of the container.
Furthermore the present invention also provides a method for dosing a persona! care fluid with a manual dosing device according to the present invention, wherein the housing cap with a dispensing stroke is urged from a starting position relative to the fluid container during which relative movement the housing cap is guided by at least two internal guide surfaces along an outer surface of both the housing and the fluid container. In an alternative embodiment of the dosing method the housing cap may relatively be moved away from the fluid container towards the starting position, during which return movement the housing cap may be guided by at least two 5 internal guide surfaces along an outer surface of both the housing and the fluid container. When referring to a “relative movement” is indicated that the housing cap (that is connecting to the micropump plunger, micropump plunger stem with the fluid nozzle and fluid nozzle tip) and the fluid container (with connected housing) are movable with respect to each other. For instance the housing cap with the fluid nozzle tip may be held in a stationary position (e.g. to bring the cap/nozzle tip in an immovable correct position connecting to a body opening or body part) while the fluid container is moved by exerting a pressure to the bottom side. However the relative movement may also imply a movement from both sides or only form the cap/nozzle tip side). With such method of dosing personal care fluids the advantages may be realised as above listed in relation to the personal care fluid manual dosing device and the personal care fluid dispenser combination according to the present invention, which advantages are hereby also included by reference in relation to the dosing method according to the present invention.
During the dosing at least two of the internal guid surfaces of the housing cap may be contacting the two outer surfaces of the housing and the fluid container at longitudinally separated positions; providing the housing cap during the dispensing stroke and/or the return stroke a stable orientation relative to the housing and fluid container.
In an alternative embodiment of the dosing method an internal piston located in the fluid container may during the return stroke be sucked in a direction towards the housing cap resulting in outside air being sucked in an air filled compartment that is located on the side of the internal piston faced away from the housing cap. So contact between the personal care fluid in the container and outside air may be prevented which may be advantageous for maintaining the quality of the personal care fluid in the container. Furthermore this method may enable the use of a dosing device in any desired orientation.
To enable a well-controlled dosing it is desired that the internal piston located in the fluid container during the dispensing stroke is held in a stationary position. Holding the internal piston at this stage of the dosing process in a stationary position enables to maintain a minimum level of pressure on the personal care fluid in the container. The invention will further be illuminated in relation to the non-limitative embodiments shown in the attached figures. Herein shows: figure 1 a perspective view on a personal care fluid dispenser combination according to the invention, comprising a dosing device that is attached to a personal care fluid container; figure 2 a perspective view of a cross-section through the personal care fluid dispenser combination as shown in figure 1; figures 3A — 3C three perspective side views on different fluid nozzle tips as being part of the personal care fluid manual dosing device according to the invention; figures 4A — 4C three internal perspective views on different fluid nozzle tips with internal flow guides as being part of the personal care fluid manual dosing device according to the invention, and figure 5 a cross section through an alternative embodiment of a personal care fluid dispenser combination according to the invention with a transverse to the fluid nozzle tip; and figure 6 a cross section through an alternative embodiment of a personal care fluid dispenser combination according to the invention including a diptube supply to the micropump.
Figure 1 shows a perspective view on a personal care fluid dispenser combination 1 according to the invention, showing a part of a personal care fluid container 2 and a housing cap 3. The housing cap 3 is in longitudinal direction moveable relative to the fluid container 2, and is provided with a fluid nozzle tip 4. The housing cap 3 has a pre-shaped outside with a support surface 5 that is suitable for engagement by one or more finders of a user.
Figure 2 a perspective view of a cross-section through the personal care fluid dispenser combination 1 as shown in figure 1. A personal care fluid manual dosing device 10 is attached to the fluid container 2 which has a bottleneck 11. The dosing device 10 comprises a housing 12 that is connected to the fluid container 2 which housing holds a micropump 13 with a micropump basis 14 including a pump chamber 15 that is stationary connected to the housing 12. The pump chamber 15 has a feed opening 16 that connects to a personal care fluid compartment 17 of the fluid container 2. The micropump 13 furthermore has a micropump plunger 18 with a micro-pump filling spring 19 that is moveable relative to the micropump chamber 15 and that is provided with a micropump plunger stem 20 incorporating a personal care fluid transit channel 21 leading towards a fluid nozzle 22. The fluid nozzle tip 4 connects to the micropump plunger stem 20. Furthermore the housing cap 3 is moveable connected to the housing 12, covering the housing 12, the micropump 13 and an upper part of the fluid container 2. The housing cap 3 has an opening 23 leaving through the nozzle side of the micropump plunger stem 20. For stability of the orientation of the housing cap 3 relative to the housing 12 and the fluid container 2 the housing cap 3 has two spaced-apart internal guide surfaces 24, 25 — here internal cylindrical guide surfaces 24, 25 - to contact both, the housing 12, and the fluid container 2.
This figure 2 also shows that personal care fluid container 2 has an internal piston 26 separating the personal care fluid compartment 17 from an air filled compartment 27 that is in open communication with the outside air. The fluid container 2 here shown is assembled from a bottom part 28 and an upper bottle part 29 that allows the introduction of the internal piston 26 in the container 2 before assembly of the bottom part 28 and the upper bottle part 29. The fluid nozzle tip 4 connecting to the micropump plunger stem 20 here is shown including a tensioned closing valve.
Figures 3A — 3C show three perspective side views on different fluid nozzle tips 30, 31, 32 as being part of the personal care fluid manual dosing device 10 as shown in figure 2. The nozzle tip 30 shown in figure 3A has a smooth tapered shape, while the nozzle tip 31 shown in figure 3B has a tapered shape wherein some fongitudinal grooves 34 (external longitudinal slots) are provided to enable compensation of undesired over- and/or underpressure differences in a body orifice during use of the personal care fluid dispenser combination 1. In figure 3C the nozzle tip 32 shows a tapered shape with a heavily longitudinal profiled surface 35. Figures 4A — 4C show three internal perspective views on different fluid nozzle tips 40, 41, 42 with internal flow guides 43, 44, 45 as being part of the personal care fluid manual dosing device 10 as shown in figure 2. These internal flow guides 43, 44, 45 show varying curved shapes to enable the outflow of various helical spray patterns.
Figure 5 shows an alternative embodiment of a personal care fluid dispenser combination 50 according to the invention wherein the features that are identical with the corresponding features in the personal care fluid dispenser combination 1 as shown in figures 1 and 2 are referred to with identical reference numbers. Different from the dispenser combination 1 here the micropump plunger stem 20 of the dispenser combination 50, that also incorporates a personal care fluid transit channel 21 leading towards a fluid nozzle 51 with a fluid nozzle tip 51. Different form the dispenser combination 1 in figures 1 and 2 here the fluid nozzle 51 is transverse to the longitudinal direction of the housing 12 (as well as to the longitudinal direction of the fluid container 2). This also results in an alternative housing cap 53 with a side discharge enabling an alternative directed supply method of the personal care fluid that in specific usage conditions may be desirable Or even necessary. Figure 6 shows a further alternative embodiment of a personal care fluid dispenser combination 60 according to the invention, again wherein the features that are identical with the corresponding features in the personal care fluid dispenser combination 1 as shown in figures 1 and 2 are referred to with identical reference numbers. The pump chamber 15 of the micropump 13 here has a feed opening 61 that connects to a diptube 62 which in turn connects to the bottom side of the personal care fluid compartment 17 of a fluid container 63. The diptube 62 feed of personal care fluid from the fluid container 63 requires a specific - mainly vertical - orientation of the fluid container 63 during suction of personal care fluid out of the fluid compartment 17. A further difference with the fluid dispenser combination 1 as shown in figures 1 and 2 is that the internal piston 26 as shown there is superfluous which also makes it possible to use a single pieced fluid container 63 (thus without separate bottom and upper bottle parts 28, 29 as used in the previous fluid dispenser combination 1.
