Abstract

A manually operated piston pump for small dispensing containers, e.g. for cosmetic products or liquid soap, has a locking arrangement comprising a sleeve (8) which projects down into the body (1) of the pump around the stem (5) of the piston (4) and has in its upper rim an inverted L-shaped recess, co- operating with a rib (13) on the lower end of the actuating and dispensing button (7) so that in one angular position of the button (7) the button can be freely reciprocated, whilst in another angular position, preferably about 90 DEG from the first, it is locked in its rest position. A flange (10) on the sleeve (8) secures a screw mounting cap (2) to the pump body (1) whilst allowing relative rotation. <IMAGE>

Description

SPECIFICATION Manually operated pump for small dispensers This invention relates to a manually operated pump, for example for dispensing liquid or pasty products from small containers.
This method of dispensing is currently used for household or cosmetic products or for liquid soaps.
With the aim of avoiding unauthorised use, it is of advantage to be able to provide means for locking the pump which are easy to operate but which equally make it possible to prevent young children operating the pump accidentally.
The aim of the invention is to provide such a pump having the advantages of easy manufacture and assembly with minimum trouble, as well as the freedom to allow particular orientation in the event of such a pump being fitted to non-round containers, where the dispensing head is extended by the provision of a relatively long spout.
According to the present invention a manually operated pump for dispensing liquid or pasty products from small containers comprises a pump body secured to a cap for mounting on the neck of the container and containing a piston having an actuating stem of which the free end engages in the lower end of a dispensing head forming an actuating button, characterised in that it incorporates an intermediate sleeve freely surrounding the stem of the piston and the lower end of the button, the sleeve being in snap engagement and secured against angular and axial movement in the open end of the pump body, the sleeve having at an intermediate portion of its length a flange which comes into engagement with a annular shoulder on the cap to secure the cap to the pump body whilst allowing rotation, the sleeve having at its upper end a recess of inverted L shape co-operating with an external longitudinal rib or projection on the lower portion of the button to allow the button to be reciprocated when the rib or projection is in the vertical arm of the Land preventing such movement by abutment of the end of the rib or projection, when, by rotating the button, the rib or projection is brought over the lateral arm of the L in the rest position of the piston.
In one preferred embodiment, the open end of the body of the pump is surrounded by a flange which extends perpendicular to the axis of the pump and has a diameter slightly less than the internal diameter of the top wall of the cap, against which the flange engages to return the pump on the container in the desired angular position, by screwing down the cap on the neck of the container.
The inverted L recess in the sleeve could have a horizontal portion corresponding at least to the width of the rib on the lower portion of the button, this horizontal portion being joined to the vertical portion by a curved ramp, a side wall of the end of the vertical portion of the L forming a first abutment and the end of the horizontal portion forming a second abutment, for limiting the rotation of the button.
The angle through which the button rotates between the rest position and the operating position is preferably about 90 .
It is of advantage for the external surface of the stem where it is inserted in the body of the pump to have longitudinal splines preventing any rotation of the sleeve with respect to the pump body.
The invention wili be better understood by reading the following detailed description and inspection of the accompanying drawings which illustrate, by way of non-limiting example, one embodiment of the invention. In the drawings: Figure 1 is a diagrammatic elevation, partially sectioned, of a pump according to the invention; Figures 2 and 3 are perspective views of the locking system for the actuating button of the pump, shown in its rest position and its position of use.
The pump illustrated in the drawings comprises essentially a pump body 1 of which the upper end terminates in a flange 16 which allows the pump body to be clamped onto the neck 3 of the container by means of a standard screw cap 2. Within the pump body 1 a piston 4, ending in a stem 5, can reciprocate movements. Onto the free end of the stem of the piston 5 there is fitted the lower end of a stem 6 leading into a spray head forming an actuating button 7.
Into the open end of the pump body 1 there is forcibly inserted an intermediate sleeve 8 which has an annular rib 9 in snap engagement in a corresponding groove in the pump body 1 to secure the sleeve 8 in the pump body 1. On at least part of the surface of the sleeve 8 in contact with the internal surface of the pump body 1 longitudinal ribs or splines 20 which prevent any rotation of the sleeve 8 in the pump body 1.
The sleeve 8 has in its intermediate region above the rib 9 a flange 10 having a shoulder which comes into engagement with a complementary annular shoulder 11 on the cap 2.
The upper rim of the sleeve 8 is cut away to form a recess 12 of inverted L shape, of which the horizontal portion 18 is perpendicular to the axis of the sleeve and the vertical portion 19 is parallel to that axis. The side wall 14 of the vertical portion 19 subtends at the axis an angle of 90 with the end 15 of the horizontal portion 18. The lower edge of the horizontal portion 18 is joined to the inner edge of the vertical portion 19 by a ramp. The width of the vertical portion 19 is slightly greater than the width of a rib 13 carried on the external wall of the lower part of the actuating button 6, such as to allow free sliding movement of this rib 13 is in engagement with the side wall 14 of the vertical arm 19. The length of the rib 13 is such that in the rest position of the pump the button 7 can be turned in order to bring the rib 13 into engagement against the end 15 of the horizontal arm 18, such as to prevent any actuation of the pump.
It will be understood that modifications may be made. For example the rib 13 could be replaced buy a projection of any kind having the position and effect of the end of rib 13.
