Definitions

the invention relates to a spraying device as this is described in the preable of the main claim.
the liquid drops wille unite so that the size of the drops will increase.
the sprayed mixture e.g. the spray will also have a less uniform composition.
a duct section running practically parallel to the axis of the cap and of the container, connects to the section of the air duct running practically parallel to the axis of the bore, which first mentioned section extends through a substantially cylindrical part of the cap, such that the inner end of the air duct connects directly to the space in the container which is normally situated above the highest liquid level.
the air duct can then simultaneously serve for sucking in air into the container when, after a spraying has taken place, it is released and will take up its original shape again. Due to this, the inflowing air will have a considerable velocity, by which a good cleaning of the narrow discharge bore is guaranteed.
a duct section running substantially parallel to the axis of the cap and of the container connects to the section of the air duct running practically parallel to the axis of the bore, which first mentioned section extends as far as into the space which is situated within a substantially cylindrical part of the cap, which cylindrical part, near its innermost edge, is connected to a substantially radially extending part of the supporting means, in which radially extending part one or more openings are situated for receiving air in the container when after discharge of the formed mixture, it takes up its original shape again.
the axis of the bore can be square to the axis of the container and of the cap, according to the invention it can also be provided for, that the axis of the bore encloses an angle between 10° to 150° with the extension of the axis of the container and of the cap.
the discharged mixture or the spray can thus then be directed upward or downward, depending on the intended application of the deformable container.
the spraying device shown in the drawing comprises a closing cap 1, which is provided with screw-thread 2 for applying it onto the neck 3 of a deformable container 4, of which only a small part is shown in the drawing.
the supporting means 5 are connected to the innermost edge 7 of the substantially cylindrical part 6 of the cap 1.
the part 9 of the supporting means 5 running radially in relation to the axis 8 of the container 4 carries a valve support 10.
the valve support 10 is provided with the valve seat 11 on which the movable valve 12 rests.
the support 10 is provided with the dip tube 13, which extends as far as near the not illustrated bottom of the container 4.
the valve 12 consists of the part 14 sealing in relation to the valve seat 11 and the cylindrical part 15 extending downwardly with an opening 16 in the transition between both parts.
the opening 16 ends in a chamber 17, which is formed in the upper plane 18 of the valve 12. It is also possible that more than one opening 16 and chamber 17 are present.
liquid Upon applying pressure on the container 4 by hand, liquid will be forced under the valve 12 through the dip tube 13 and the valve 12 will then be lifted from its seat 11 and with its upper plane 18 come to lie against the inner plane 19 of the cap 1. The liquid will then flow through the opening 16 into the chamber 17 and there be mixed with air which is forced from the container 4 into the chamber 17 through at least one opening 20 in the radial part 9 of the supporting means 5.
the formed mixture will leave the chamber 17 through an opening 21, the axis 22 of which can extend in the direction of the axis 8.
the bore 23 connects to the opening 21, the axis 24 of which bore is practically square to the axis 22 of the opening 21.
a section 25 of an air duct 26 connects to the bore 23, which section 25 runs substantially parallel to the axis 24 of the bore 23.
the further section 27 of the air duct 26 extends through the cylindrical part 6 of the cap 1.
the inner end 28 of the air duct 27 ends in the space 29 of the container 4, which space is in general above the level 30 of the liquid 31 present in the container 4.
the container 4 When the pressure on the container 4 is relieved, the container 4 will take up its original shape again. Hereby, the valve 12 will be closed and air will be sucked into the container 4 through the bore 23, the air duct 26, the opening 21, along the upper plane 18 of the valve 12, through the chamber 17 and through the openings 16 and 20. This will contribute to cleaning of the naturally small openings 16, 21 and 23, so that these will not easily get jammed by any possible curing liquid.
section 27 of the air duct 26 can also extend as far as into the space 32, which is formed between the cylindrical part 6 of the cap 1 and the cylindrical part 15 of the valve 12. The section 27 will then be replaced by the section 27a.
the mouth of the bore 23 can be enlarged and a sieve or other means can be mounted in the enlarged part.
a better cleaning of the sieve or other means will be obtained here as well, when the container 4 takes up its original shape again after a deformation.
this axis 24 of the bore 23 is square to the axis 8 of the cap 1 and the container 4, it will be obvious, as already mentioned above, that this axis 24 can also enclose an angle ⁇ with the axis 8.
this angle ⁇ can be between 10° and 150°, depending on the intended application of the deformable container.
the air duct 25 will remain parallel to the axis 24 of the bore 23.
the inventive idea can also be applied with a spraying device which is not provided with a shut-off valve.
a shut-off valve In general, the application of such a valve has the advantage, that upon squeezing the container, the mixture immediately flows out, since the level of the liquid in state of rest is up to beneath the valve.
