Description
2~6~7~3 Spraying device fo~ defo~mable container.
The invention relates to a spraying device for a defor-mable aontainer J ~hich device comprises a closing cap for the ~ontainer and supporting means ~irectly or indirectly 5 conneçted therewith ta which a dip tube projecting in the container i~ mounted through which, on squeezing the contai-ner, liquid will be forced into a chamber situated ~ithin ; the cap, in which chamber the liquid is mixed with air flowing from the container into the chamher, fro~ which 10 chambe~ the mixture is discharged outwardly ~hrough an opening ~re~ent in the cap, which encloses ~n angle with the axis o~ khe cap and the con~ainer, through which opening air ran ~low into the container, when the container takes up its original ~hape again after discharge of the formed mixture.
~uch a de~ice is known from US-A-4.673.110. When with this known device the angle, which the opening in the clo-sing cap encloses with the axis o the ~ap, is t~o large, spraying of the liquid will be adversely affected.
Thus, with increasing deflection of the mixture or the 20 spray, the liguid drops will unite so that the size of the drops will lncrease. ~he sprayed mixture, e.g. the spray will also have a less uniform composition.
~ n order to ob~iate this difficulty and adapt the de~ice for spraying a liquid-air-mixture in several direc-25 tions, according to the invention it is provi~ed f~r, thatan opening situated in th~ closing cap ends laterally in a bore made in the cap, which bore is open at one end for discharge of the formed mixture outwardly, while an air duct ends in the bott~m of the bore, situated opposite the open 30 end, the axis of the alr duct extends substantially parallel ~ to that of sai~ bore and whiah air duct on th2 other hand is ! aonnected to a space in the container ~hich is n~rmally situated above the highest liquid level in the container.
Owing to the fact that the openin~ ends laterally in 35 the bore, it is achieved, ~hat the mixture arrivinq in the bore is subjected to an air flow emerging from said air duct and being substantially s~uare t~ th~ direction of flow of ~he mixt~re, which air flow produces the deflection of the ~ , ~
~066783 mixture, the spray, while maintaining its quality.
According to a preferred embodiment of the invention, it can be provided for, that a duct section, running practi-cally parallel to the axis of the cap and of the container, 5 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, ~uch that the inner end of the air duct connects directly to the space in the container which is normally 10 situated above the hignest liquid level.
The air duct can then simultaneously serve for sucking in air into t~e 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 considera-15 ble velocity, by which a good cleaning of the narrow dis-charge bore is guaranteed.
There is also the possibility that a duct section running substantially parallel to the axis of the cap and of the container connects to the ~ection of the air duct run-20 ning practically parallel to the axis of the bore, whichfirst 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 25 supporting means, in whi~h radially extending part one or more openings are situated for receiv1ng air in the contai-ner when after discharge of the formed mixture, it takes up its original shape again.
Naturally, both air ducts could be applied simultane-30 ousl~, but this only leads to a more complicated and thusmore expensive spraying device.
Although the axis ~f 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 35 encloses an angle between 10 to 150~ with the extension of the ~xis 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.
2~783 Further, it will be obvious, that the features applied with the invention are also useful with other embodiments of spraying devices, than described in the US patent specifica-tion mentioned above.
The invention will now be explained on the basis of embodiments, shown in the drawing, which shows a vertical section through a spraying device according to the inven-tion. In the drawing, a first embodiment is depicted in full lines and another possible embodiment in dash lines.
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 15 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. Opposite to the 20 valve seat 11 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 relati-on to the valve seat 11 and the cylindrical part 15 exten-25 ding downwardly with an opening 16 in the transition between both parts. The opening 16 end~ 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.
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 ~e 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 35 opening 16 into the cha~ber 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 2~7~3 opening 21, the axis 22 of which can exte~d 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 10 container 4, which space is in general above the level 30 of the liquid 31 present in the container 4.
As already mentioned above, a liquid-air-mixture will be formed in the chamber 17 upon squeezing the container 4.
This mixture leaves the chamber 17 through the opening 21 15 and arrives in the bore 23. Simultaneously, air is forced to the inner end of the bore 23 through the duct 25, so that the mixture flowing from the opening 21 in the direction of the axis 22 is ~eflected in the direction of the axis 24 of the bore 23.
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 ope-ning 21, along th~ upper plane 18 of the valve 12, through 25 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.
With dash lines it is indicated, that the section 27 of 30 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 o the valve 12. The seGtion 27 will then be replaced by the section 27a.
As already mentioned above, it is possible to apply 35 both a duct 27 and a duct 27a in the cap 1.
When one does not want ~o use the device described above for discharging a mixture, v~pour, liquid particles, but for discharging foam, means known per se can be applied.
For example, the mouth of the bore 23 can be enlarged and a sieve or other means can be mounted in the enlarged pa~t. ~y the presence of the air duct 26, 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 defor-5 mation.
Although in the drawing the axis 24 of the bore 23 is ~quare 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 acute angle B with the axis 8. For 10 example, this angle B can be between 10 and 150 , depending on the intsnded application of the deformable container.
Therein, the air duct 25 will remain parallel to the axis 24 of the bore 23.
It will be obvious, that only one possible embodiment 15 o~ a device according to the invention is illustrated in the drawing and discussed above, and that many modifications can be made without falling heyond the inventive idea.
Thus, the inventive idea can also be applied ~ith a spraying device which is not provided with a shut-off valve.
20 In general, the application of such a valve has the advan-tage, that upon squeeæing the contaiher, the mixture immedi-ately flows out, s~nce the level of t~e liquid in state of rest is up to beneath the valve.
The invention relates to a spraying device for a defor-mable aontainer J ~hich device comprises a closing cap for the ~ontainer and supporting means ~irectly or indirectly 5 conneçted therewith ta which a dip tube projecting in the container i~ mounted through which, on squeezing the contai-ner, liquid will be forced into a chamber situated ~ithin ; the cap, in which chamber the liquid is mixed with air flowing from the container into the chamher, fro~ which 10 chambe~ the mixture is discharged outwardly ~hrough an opening ~re~ent in the cap, which encloses ~n angle with the axis o~ khe cap and the con~ainer, through which opening air ran ~low into the container, when the container takes up its original ~hape again after discharge of the formed mixture.

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. Opposite to the 20 valve seat 11 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 relati-on to the valve seat 11 and the cylindrical part 15 exten-25 ding downwardly with an opening 16 in the transition between both parts. The opening 16 end~ 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.
