Abstract
Description
- 1. Field of the Invention
- The present invention relates to a pushbutton for operating a pump or valve for dispensing a fluid substance contained in a container.
- 2. Discussion of the Background Art
- To controlledly dispense fluid substances (in particular liquid or creamy substances contained in a container under or not under pressure), it is known to use valves or pumps mounted on the mouth of such containers: these pumps have an outwardly projecting hollow stem, on the free end of which there is mounted an operating pushbutton with a nozzle, insert or hole through which the fluid substance originating from the pump can be dispensed through said nozzle following axial translation of the pushbutton, when the pushbutton is pressed with a finger of one hand.
- In pushbuttons of known type the dispensing nozzle moves together with the pushbutton, to undergo a longitudinal translation in one direction or the other when the pushbutton is pressed or released: as a result, the fluid substance dispensed through the nozzle does not occupy a fixed position relative to the pump, but moves within space following the movement of the pushbutton: in many cases this represents a drawback, for example when the fluid substance is to be dispensed onto a well defined fixed point (which can be important if the substance is coloured or oily, or consist of a pharmaceutical substance which has to be applied to a well defined limited point).
- The main object of the present invention is therefore to provide a pushbutton mountable on the movable stem of a pump or the like and having a dispensing nozzle which maintains its position at rest and fixed relative to the pump, whatever the position assumed by the stem of the pump during its rest or operation.
- Another object is to provide a pushbutton of the aforestated type which is of economical production and reliable operation.
- These and other objects are attained by a pushbutton characterised by comprising:
- two separate pushbutton portions connected together and translatable axially one relative to the other, namely a movable free end portion operable by a finger of one hand and, respectively, a main pushbutton portion provided with elements for its retention on the pump or on a rigid body fixed to the pump;
- a seat provided in said pushbutton end portion, to sealedly house the free end of the stem of said pump;
- a nozzle for discharging the fluid substance to the outside of the pushbutton, said nozzle being provided within the pushbutton main portion in which there is also provided an aperture into which at least the pump stem can extend;
- two tubular appendices projecting one towards the other, one from said end portion and the other from said main portion of the pushbutton, the axes of said appendices being parallel to the axis of said seat for the stem end;
- conduits provided in the two pushbutton portions, to connect said seat for the stem to the cavity of that tubular appendix projecting from the pushbutton end portion and, respectively, to connect said nozzle to the cavity of that tubular appendix of the pushbutton main portion;
- one of said two tubular appendices being inserted into and sealedly translatable within the cavity of the other tubular appendix to hence directly connect said nozzle to said seat for the pump stem.
- Preferably, said retention elements consist of a plurality of appendices or a continuous tubular wall projecting from said pushbutton main portion on the opposite side to that from which the tubular appendix forming part of the pushbutton main portion projects, said appendices or tubular wall having dimensions such as to fit over the ring cap by which the pump is fixed on to the mouth of a container, and being provided with inwardly projecting teeth or ribs to secure the pushbutton to the ring cap.
- The structure and operation of the pump will be more apparent from the ensuing description of one embodiment thereof given by way of non-limiting example with reference to the accompanying drawing, in which
FIGS. 1 and 2 are sectional views of the pump in its rest position and, respectively, in its operating position for dispensing fluid substance. - From the drawing it can be seen that a
pump 2 is fixed by means of aring cap 3 onto the mouth of a container 1 (containing a fluid substance, not shown, to be dispensed): both the pump and the ring cap are of any known type. Ahollow stem 4, also of known type for operating the pump, projects from the pump upper end (with respect to the drawing). - The pushbutton of the present invention is shown in schematised section in
FIG. 1 (pump at rest) and inFIG. 2 (pump operated to dispense fluid substance represented as a dashed-line cone on the right ofFIG. 2 ). - The pushbutton comprises two separate pushbutton portions, namely a main portion indicated by 5 and a movable free end portion indicated by 6.
- The pushbutton
main portion 5 presents a central aperture (not shown in the drawing) through which both thestem 4 and the top of thepump 2 extend, the pump being securely fixed sealedly on the mouth of thecontainer 1 by thering cap 3. From the bottom (with respect to the drawing) of thepushbutton portion 5 there downwardly extends a continuous tubular wall 7 (which can also consist of a plurality of flexible appendices) bounding a space into which thering cap 3 is inserted and securely retained therein by arib 8 or a plurality of teeth having the same purpose and snap-engaging below the lower edge of the ring cap, to hence lock the pushbuttonmain portion 5 in a fixed position. - From the top of the pushbutton
main portion 5 there upwardly projects a cylindricaltubular appendix 9, thecavity 10 of which extends as far as anozzle 11 provided on one side of theportion 5; as can be seen from the drawing, the axis of theappendix 9 is parallel to the axis of thestem 4. From the lower end of thepushbutton end portion 6, two hollowtubular appendices stem 4 and of theappendix 9. - At the free end of the cavity of the
appendix 12 there is provided a seat into which the free end of thestem 4 can be sealedly inserted by pressing; the cavities of thetubular appendices conduits 15 which are closed at one end by aseal plug 16. - The cavity of the
appendix 13 has, at least in proximity to its free end, a diameter such as to enable at least an end portion of theappendix 9 to penetrate into and sealedly slide axially within it, as will be clear on comparingFIG. 1 withFIG. 2 . - It will now be assumed that the pushbutton and pump are in the rest condition shown in
FIG. 1 , in which fluid substance cannot flow from the container to the outside. On pressing the free upper end of thepushbutton portion 6 with a finger of one hand, thestem 4 translates axially downwards (to hence operate the pump) and the upper end of thetubular appendix 9 penetrates into the widened portion of the cavity of theappendix 13. In this manner, as is easily apparent, the pressurized fluid substance emerging from thestem 4 passes through theconduits 15 and thecavities tubular appendices nozzle 11. - A very important characteristic of the described pushbutton is that the
nozzle 11 remains at rest on the container, i.e. it maintains a constant stable position on the pushbutton main portion, whether the pump is in its rest or operating condition.
