f Plug-like atomizer head for a container

with walls that can be pressed in by hand.

The innovation relates to the atomization of liquids that are in containers with walls that can be pressed in by hand.

Stopper-like attachable atomizer heads for containers with flexible walls are known per se; Such containers contain liquid products , in particular liquid pharmaceutical products or products used in the household. The main disadvantage of these atomizers, however, is that they atomize the * products too coarsely and only sparingly space them out.

fanned out.

The present innovation is therefore based on the task of avoiding the disadvantages of the known atomizer heads.

The object of the innovation is an atomizer head that can be attached in the manner of a plug for a container with walls that can be pressed in by hand; This atomizer head is characterized in that it has a ^{vortex chamber which is arranged coaxially 1} with the stopper and which can be connected through the stopper to the air in the container on the one hand and to the liquid in the container on the other.

-A-

According to one embodiment of the subject matter of the innovation is the swirl chamber between the end face of an axially directed pipe part formed in the I plug and a This pipe part covering nozzle is cut out and receives the liquid through an axial bore in this pipe part and the air through ducts formed between the side wall of the nozzle and hollow grooves in the side wall of the pipe part are.

According to a further embodiment of the subject matter of

/ The innovation is the vortex chamber in the underside of a transverse wall formed, which is located in the upper part of the stopper, and is partially through the face of the liquid Sealed supply line leading into the swirl chamber.

The innovation also affects containers that can be pushed in by hand Walls, as far as they are equipped with such plug-like atomizer heads.

Some embodiments of the innovation are given below described with reference to drawings showing the following:

1 shows an axial section through a first embodiment ν 'of a plug-like atomizer head according to the invention

without nozzle;

Fig. 2 is a plan view of the atomizer head of Fig. 1;

3 shows a view of the atomizer head according to FIG. 1 and with the associated nozzle, partly as an external view, partly on average;

Fig. 4 shows a bottom view of a second embodiment

a plug-like atomizer head according to the invention;

FIG. 5 is a sectional view taken along line V-V in FIG. 4.

The plug-like atomizer head according to FIGS. 1 to 3 comprises a main part which extends into the neck of a (not drawn) container with soft walls can be pressed; the atomizer head can be extended up to the ring shoulder 2 and it is held on the annular ribs 3 by friction.

( ) The atomizer head contains a cylindrical tube part 4 which runs coaxially with the main part 1 and in the lower section of which a feed line 5 is inserted and held at its upper end; the other end of the supply line 5 extends down to the bottom of the container. The feed line 5 conveys the liquid located in the container through the bore into a swirl chamber 6.

In addition, there are several holes 8 in a disk-shaped part 9 which connects the tube part 4 to the main part 1

“Drilled through which the inside of the container is connected with four grooves 10 which are cut laterally into the pipe part. These grooves 10 form together with the side wall of the Tube part 4 covering nozzle 11 lines for the supply of air into the vortex chamber 6. This chamber 6 is located between the nozzle 11 and the end face of the pipe part 4.

If the user exerts a hand pressure on the depressible walls of a container, which with the one shown in Figs. up to 3 atomizer head shown is equipped, the following happens:

- the liquid rises through the supply line 5 and the bore 7 into the vortex chamber 6,

- at the same time is in this vortex chamber 6 through the Lö-

ϊ more like 8 and air is stirred into the grooves 10,

ί - an air-liquid mixture emerges from the chamber 6

through the atomizer opening 12 under pressure.

The plug-like atomizer head in the embodiment according to FIGS. 4 and 5 differs from that above
very flat only through the design of the vortex chamber and the air supply line.

ΐ Then the liquid feed line 5 is taken from the four

^J jumping edges 13 of a blind hole with a cruciform cross-section held, in which the grooves 14 in connection

with said supply line 5, form the air supply from the container into the chamber 15, which is located in the transverse wall 16 of the stopper is formed and is partially closed by the end face of the liquid feed line 5.

When the container is pressed in by hand, the air from the container is prevented from entering the chamber through the grooves 14 15 while the liquid is conveyed through the feed line into the chamber.

) The pressure then causes the atomization of the air-liquid

keits mixture caused through the opening 17 therethrough.

Of course, the innovation is not limited to the embodiments described and drawn; it can depending on the various intended fields of application are executed in numerous variants familiar to the person skilled in the art, without leaving the scope of the innovation.
