However, the ready-to-use container (10) is not complete with Liquid filled, but also has an air-filled space (18) above the liquid level (17). Compressed air is fed into space (18). Inside the liquid container (10) is concentric to the jacket (12) a cylinder (19), the edge of which is attached to the bottom of the liquid container (10). The cylinder (19) has at its inner end a pressure accumulator valve (20) au / that is designed as a check valve and air only in the direction of the space (18) lets through. The cylinder (19) is, for example, screwably connected to the bottom of the liquid container (10). Around To fill liquid (16) into the liquid container (10), the cylinder (19) is screwed on. After partial filling with liquid, the cylinder (19) is screwed back into the bottom of the liquid container (10).

A hollow piston (21) is arranged displaceably in the cylinder (19). A manually operated air pump device (22) has the cylinder (19) and a piston (21). At the inner end of the piston (21) there is an air intake valve (23), which is also designed as a check valve and provides air access to a pressure chamber (24) between the cylinder (19) and piston (21) allows. The air intake valve (23) contains an axially displaceable valve body (25), which has three flexible pieces (26) with a body (27) and a sealing piece (28) on the periphery of the body (27) connected is. The valve body (25) is arranged a certain distance above the end position of the piston (21). That The air intake valve (23) is closed by means of the valve body (25), which is activated by compressed air in the pressure chamber (24) is applied. In the piston (19) there is an inclined surface (29) as a stop. Against the surface (29) places |

a shoulder (30) of a stem (3D.

The liquid container (10) also has a

Release device (32) which contains a cylindrical, axially elastic part (33) that is at the bottom of the Liquid container (10) is located. With the part (33) of the stem protruding into the hollow piston (21) is at one end tied together. The stem (3D has the inclined shoulder (30) and a cylindrical push portion (3-4) at its inner end on. The pushing section (34) opens the air intake valve (23) in a certain position of the valve body (25).

"- \ The cylindrical part (33) contains air passage openings (35)

j * and is inserted into the bottom of the hollow piston (23).

\ There is also a fastening device (36) for connecting

of the piston (21) with the jacket (12) of the liquid container

(10) present.

After filling the liquid (16) and screwing in of the cylinder ^ (19) in the liquid container (10), the piston (21) is moved back and forth in the cylinder (19). the The release device (32) moves with the piston (21) so that the air intake valve (23) remains closed. That Pulling out the piston (21) increases the volume of the Pressure chamber (24), so that a negative pressure is created in it. Therefore j () moves the valve body (25) into the pressure chamber (24),

wherein the air intake valve (23) is opened. The air in

\ Cylinder (19) and air flowing through the air passage openings (35)

flows into the pressure chamber (24). This air passes through

the opposite movement of the piston (21) in the

f Pressure chamber (24) compressed.

The repetition of the above-described reciprocating movements of the piston (21) increases the pressure in the pressure chamber. This Pressure is propagated into space (18) via the pressure accumulator valve (20). Which in the course of the piston movements Gradually increasing pressure creates a force that counteracts the piston movements, so that the piston movements in the course

slow down with time. The greater the pressure in the Pressure chamber (24), the more force is required for the piston movement.

A large force indicates that there is a sufficiently high pressure in space (18). In this case, in the Liquid container (10) pushed in piston (21) the part (33) pressed inwards. This causes the stem to move (3D against the air intake valve (23), which is opened by means of the push section (3A) and the compressed air in de /. Pressure chamber

rv (34) over the hollow cylinder (21) and the

Air passage openings (35) can escape. When the pressure in the pressure chamber (24) drops, it closes Pressure accumulator valve (20) in the liquid container (10).

Then the piston (21) is pushed into the interior of the liquid container (10) with little force in its one end position moved and attached to the liquid container (10).

If then pressure is exerted on the head (4), the valve (11) is opened, so that the liquid (16) under the high pressure prevailing in the space (18) via the suction pipe (15), the valve (11) and the outlet channel (9) enters the channel (6), } and is pressed from there into the guide tube (2)

the end (3) of which exits a jet of liquid which is directed onto the interdental spaces or the gums.

With the pipe socket (5) of the head (4) is in another embodiment, which is shown in Fig. 2, a guide tube (37) connected, one end of which is nozzle-shaped, while at the other end in a larger pipe section (38) a flutter valve (39) is arranged. The flutter valve (39) interrupts the flow from the head (4) into the guide tube (37) incoming liquid flow, so that at the end O) a pulsating liquid jet emerges, which is next to the Cleaning effect has a particularly good massage effect.

Fig. 3 shows a head (4) connected to a guide tube (40) * that as well as the guide tube (37) with a pipe section (38) is provided in which a flutter valve (39) is located. The free end of the guide tube (40) is designed as a shower head (41) from which jets of liquid emerge in a pulsating manner. This results in a good massage effect for the gums over a large area.

The ϊΰίΐ of the Lüftpüinpcinrichiung (23) srzeugbsrs pressure ini The liquid container (10) is because of the piston (21)
