DESCRIPTION:
BRIEF SUMMARY
The invention relates to a flexible bottle making it possible to effect either spraying or drop by drop dispensing of a liquid contained therein, a bottle of the kind containing in its upper portion a spraying orifice associated with means for the take up of the liquid into the bottle, and a drop by drop dispensing orifice with a larger cross section than that of the spraying orifice, provision, moreover, being made for the selection of one of the orifices.
Such a bottle makes it possible to choose, depending on the use envisaged for the product of this bottle, between the spraying obtained by the forces of successive compression and relaxation of the wall of the bottle, and the drop by drop dispensing.
This is an appreciable advantage of this kind of bottle.
However, the handling of such a bottle, particularly with a view to producing the spraying, requires improvement.
The object of the invention is, above all, to provide a flexible bottle of the kind defined above which should be more convenient to handle and to use than the kind of bottles known to data whilst making it possible to ensure either the spraying or drop by drop dispensing in equally good conditions.
A flexible bottle of the kind defined above is characterised in that it has a flattened shape and has two narrow flat facing sides and that provision is made respectively for the spraying orifice and dispensing orifice towards the top of each narrow side and that the selection means comprise for each orifice, a push shutter which is displaceable in translation along the direction of the large dimension of the corresponding side, between one position wherein the orifice associated with the push plate is closed and another position wherein the said orifice is open.
Such a bottle is easy to manipulate and allows the direction of the jet which will emerge to be properly set before any pressure is exerted on the bottle walls with a view to spraying.
Preferably, the bottle is provided with a cap fixed by catch engagement in particular, this cap being provided with a sealing skirt capable of entering into the upper portion of the bottle and to bear in a leakproof manner against the internal surface of this bottle; the above mentioned orifices and push shutters are provided on the cap.
Each orifice is advantageously provided in a nozzle which comprises a flange projecting towards the outside capable of bearing in a leakproof manner against the opposite side of the push shutter, this push shutter comprising an opening with a larger diameter than that of the corresponding orifice, this opening being capable of coming to be opposite the orifice when the push plate is in the open position.
The bottle generally comprises, in the upper portion, a neck with a smaller cross section whereon the cap comes to be located, the cross section of the cap having substantially the same dimensions as those of the portion of the bottle situated below the neck.
The push shutters are guided in grooves provided on the cap. These push plates have a flat external surface essentially situated in the plane of the associated side of the bottle, the said external surface comprising, however, projecting ribs with a view to facilitating the action on the push plate.
The cap generally comprises a housing associated with each orifice intended to accommodate the corresponding nozzle. Moreover, a return forming an appendage of the cap towards the bottom of the bottle is associated with the spraying orifice, this return being intended to carry a plunger tube.
Generally, the two narrow sides of the bottle are joined to each other by two much wider sides which are slightly convex towards the outside. The compressive forces applied by the user to produce the spraying are exerted on these wider sides.
Apart from the arrangements set out above, the invention consists of certain other arrangements which will be discussed in greater detail below in relation to a particular mode of embodiment described with reference to the attached drawings but which is in no way restrictive.
