The same applies to the container 1 and the valve body 23 with the associated spring body 22 , It is clear that the applicator and the container have only a very few components, whereby the assembly and manufacturing costs are kept low. In the embodiment shown here, the valve body 23 and the spring body 22 from the mouth area 3 opposite end inserted into the container. Therefore, the container 1 at this end, as shown, during assembly still open and is only after installation, for example, by the in 1a closed closure fold shown.

1c shows a side view of the in 1a illustrated container. Clearly visible here are the on the container 1 patch applicator device 2 with the main body 9 and the cap 16 ,

The 2a . 2 B and 2c show an enlarged view of the applicator 2 as well as the container only partially shown 1 , This shows 2a the applicator device with closed metering valve, while in 2 B the open position of the metering valve is shown. 2c shows the situation with removed applicator device and closed dispensing valve 21 ,

In the 2a . 2 B and 2c is clearly the design of the metering valve 15 to recognize which in the applicator device 2 is integrated. The metering valve 15 has that in the body 9 trained valve seat 19 which is formed by a recess in the base body, which has a frusto-conical shape. The in the closed position on the valve seat 19 fitting valve body 18 also has a frusto-conical shape and is configured in cross-section V-shaped.

With the valve body 18 connected is the spring body 20 , which has spirally arranged spring arms, with the valve body 18 are connected. At the valve body 18 opposite side of the spring body 20 is an annular holding section 24 formed, which clamped to the body 9 is held. These are in the main body 9 on the inside several clamping projections 25 provided, which the holding section 24 of the valve body 23 hold in position.

The spring body 20 of the metering valve 15 is on the tank 1 opposite side of the valve seat 19 arranged. The valve body 18 This way, it will be in one direction on the container 1 biased towards.

Furthermore, the 2a . 2 B and 2c clearly in the container 1 arranged dispensing valve 21 to recognize. The valve body 18 has a frusto-conical portion, which with a corresponding inclined peripheral surface of the discharge opening 11 interacts. Also the spring body 22 the dispensing valve 21 has elastic spring arms, which with the valve body 23 are connected. The spring body 22 is at the valve body 23 opposite side with an annular holding portion 26 connected, which is clamping in the cylindrical mouth area 3 is held. The spring body 22 clamps the valve body 23 towards the outlet 4 in front. The dispensing valve 21 can thereby via an operating section 27 to be moved, which with the valve body 23 connected is. The valve body 23 , the operating section 27 and the spring body 22 with the holding section 26 can be made as a one-piece plastic injection molded part made of elastic material. The operating section 27 , which is formed in a pin-shaped, thereby extending through the outlet opening 4 through and stands on the outside side of the container 1 in front.

The spring body 22 the dispensing valve 21 is on the outlet 4 opposite side of the valve body 23 arranged.

In the illustrated embodiment, the dispensing valve becomes 21 through the applicator device 2 actuated. This is due to the applicator device 2 an actuating surface 28 intended. When the applicator device 2 on the container 1 is placed, the formed on the body actuating surface comes 28 at the operating portion 27 to lie and pushes it against the action of the spring body 22 in his in the 2a and 2 B illustrated opened position. This is the exit opening 4 as long as the applicator device 2 on the container 1 is attached. 2c shows the situation with the applicator device removed. As the dispensing valve 21 not now by the actuating surface 28 is pushed into the open position, the container 1 through the dispensing valve 21 under the action of the spring body 22 closed automatically. This will cause unwanted leakage of the substance from your container 1 avoided, for example, when the applicator device 2 is replaced.

The actuating surface 28 is by a projecting pressure section 35 formed, over one or more webs 34 on the body 9 is held. The printing section 35 and the actuating surface 28 are between the metering valve 15 and the exit opening 4 in the inflow channel 31 arranged.

But even if the applicator device 2 on the container 1 is attached, the substance can not escape uncontrollably. This is done by the dosing valve 15 prevented. If no pressure is exerted on the container, the dosing valve is located 15 in his in 2a shown closed position. If there is an increased pressure in the interior of the container, for example by the user pressing on the container wall in the container 1 generates an overpressure, under the effect of this pressure, the valve body 18 of the metering valve 15 in his in 2 B shown open position moves. Now is the connection channel 14 open so that the fabric is out of the container 1 through the valve seat 19 and valve body 18 resulting gap-shaped gap and to the discharge opening 11 can get.

In the 2a . 2 B and 2c is still clearly seen that between dispensing valve 21 and the metering valve 15 remaining residual volume can be kept small. This is partly because the sealing area 29 of the metering valve 15 on the container 1 facing side of the applicator device is arranged. The sealing area 29 is located immediately adjacent to the outlet opening 4 , If, as in 2c represented, the applicator device of the container 1 removed and the cap 16 is set, the applicator device applicator device 2 Container side through the metering valve 15 and on its opposite side through the discharge opening 11 closing cap 16 locked. In this way, a closed, protected against dehydration chamber is formed in the applicator.

In addition, the residual volume remaining between the metering valve and the dispensing valve is reduced in that an annular channel section 30 is provided. This forms a the outlet opening 4 with the metering valve 15 , more precisely, with its inlet opening connecting inflow channel 31 , In the illustrated embodiment, this is done on the main body 9 the channel section 30 designed as a cylindrical circumferential region which the outlet opening 4 encloses. The channel section 30 is on its outside of one on the container 1 formed projecting support section 32 surround. This is formed by a protruding circumferential edge, wherein between support portion 32 and channel section 30 a sealing surface 33 is formed in the shape of a rounded bead. The support section 32 is in an annular recess of the body 9 added.

The 2a . 2 B and 2c let continue clearly the promoter 12 recognize which is removable on the body 9 is arranged. For this purpose are s.der promoter 12 on the inside of one or more detents 36 molded, which in one on the body 9 trained groove clamped intervention.

While in the 2a and 2c the applicator with attached cap 16 show, this is in 2 B removed, so that the substance can be dispensed from the container.

The 3a . 3b and 3c show a further embodiment of the invention, which in numerous points with the in connection with the 1a to 2c match described embodiment. Therefore, the same reference numerals are used for parts having the same function. Reference is made to the description in this regard, which for the 3a . 3b and 3c applies accordingly.

Both 3a . 3b and 3c is the mouth area 3 of the container 1 differently trained, since here a use 38 is provided. In this is the outlet 4 educated. Farther the insert has a cylindrically formed here in the interior of the container 1 protruding section 39 on which the dispensing valve 21 receives. Advantage of this embodiment is that these from the side of the mouth area 3 can be mounted by the insert 38 with the section 39 into the container opening 40 is used clamping and sealing. This makes it possible for the container 1 at its mouth area 3 opposite end already before the final assembly, z. B. by the closure fold 7 to close. Another advantage of this design is that the use 38 with the dispensing valve 21 regardless of the container 1 can be produced.
