## Abstract

A nozzle for a two-chamber container for mixing two components and applying the mixture, comprises a foldable nozzle body, comprising a mainly ring-shaped connecting part for connecting the nozzle to a container body, wherein the connecting part is arranged at an outer diameter, a tip arranged mainly in the center of the nozzle body, the tip comprises a predetermined breaking line for providing an outlet in broken state, at least one intermediate folding ring connecting the tip with the connecting part so that the tip is movable relative to the connecting part in axial direction between a folded state, where the tip is arranged mainly radially inside the connecting part, and an unfolded state, where the tip is arranged mainly outside the connecting part, and a cover plate connected with the tip.

## Claims

### Claim 1

A nozzle for a two-chamber container for mixing two components and applying the mixture, the nozzle comprising
a foldable nozzle body made from a flexible material,
the nozzle body comprising
a mainly ring-shaped connecting part for connecting the nozzle body to a container body, wherein the connecting part is arranged at an outermost diameter of the nozzle body,
a tip arranged mainly in the center of the nozzle body, wherein the tip comprises a predetermined breaking line for opening an outlet of the tip, if the predetermined breaking line is in a broken state,
at least one intermediate folding ring connecting the tip with the connecting part such that the tip is movable relative to the connecting part in axial direction between a folded state and an unfolded state, wherein, if the tip is in the folded state, the tip is arranged mainly radially inside the connecting part, and wherein, if the tip is in the unfolded state, the tip is arranged mainly outside the connecting part, and
a cover plate connected with the tip at the predetermined breaking line of the tip and directly covering the outlet of the tip, if the tip is in the folded state and positioned inside a volume bordered by the intermediate folding ring directly connected to the connecting part,
wherein, if the tip is in the unfolded state and the nozzle body is located in an upright position, a total length of the tip is defined between a bottommost end of the tip adjacent to the intermediate folding ring and an uppermost end of the tip located opposite with respect to the bottommost end of the tip and adjacent to the outlet of the tip, and wherein, if the tip is in the unfolded state and the nozzle body is located in the upright position, the cover plate, the predetermined breaking line of the tip and the outlet of the tip are provided at the uppermost end of the tip,
and further wherein, if the nozzle body is located in the upright position, the predetermined breaking line is provided at a transition area between the tip and the cover plate at the uppermost end of the tip.

### Claim 2 (depends on 1)

The nozzle according to claim 1, wherein, if the tip is in the folded state, the intermediate folding ring directly borders a maximum area Afr in folded state and the cover plate comprises an area Acp, wherein the ratio Acp/Afr is 0.75≦Acp/Afr ≦1.20.

### Claim 3 (depends on 1)

The nozzle according to claim 1, wherein the predetermined breaking line is breakable by at least one selected from turning the cover plate and pulling the cover plate.

### Claim 4 (depends on 1)

The nozzle according to claim 1, wherein the tip is movable from the folded state to the unfolded state along an opening direction and is movable in the folded state against the opening direction along an opposite pushing direction.

### Claim 5 (depends on 1)

The nozzle according to claim 1, wherein the tip is movable from the folded state to the unfolded state due to a minimum pressure p applied to the at least one selected from the intermediate folding ring and the tip, wherein the minimum pressure p is applicable to a part of the intermediate folding ring directly connected with the connecting part by means of an outlet connection of a container, wherein 0.40 bar ≦p ≦3.00 bar applies.

### Claim 6 (depends on 1)

The nozzle according to claim 1, wherein the connecting part comprises a thread for being thread onto an outlet connection of the container.

### Claim 7 (depends on 1)

The nozzle according to claim 1, wherein the nozzle body is one-piece made from a thermoplastic elastomer.

### Claim 8 (depends on 1)

The nozzle according to claim 1, wherein the thickness of the nozzle body is thinner at a transition between at least one selected from (i) the connecting part and the intermediate folding ring, (ii) the intermediate folding ring and a further intermediate folding ring, and (iii) the intermediate folding ring and the tip.

### Claim 9 (depends on 1)

A container for storing and mixing two components, the container comprising
an upper chamber for storing a first component,
a lower chamber for storing a second component and mixing the first component with the second component,
a connection channel connecting the upper chamber with the lower chamber,
a plug for sealing the connection channel, wherein the plug is movably receivable by the connection channel, and
the nozzle according to claim 1 connected to an outlet connection provided by the upper chamber.

### Claim 10 (depends on 9)

The container according to claim 9, wherein the tip of the nozzle is moveable relative to the connecting part of the nozzle body towards the lower chamber of the container such that the tip pushes the plug through the connection channel into the lower chamber.

### Claim 11 (depends on 9)

The container according to claim 9, wherein the plug comprises a stem protruding at least partially through the upper chamber towards the tip of the nozzle.

### Claim 12 (depends on 9)

The container according to claim 9, wherein the outlet connection comprises an outer thread for screwing the nozzle with the upper chamber of the container.

### Claim 13 (depends on 12)

The container according to claim 12, wherein the outlet connection abuts the intermediate folding ring of the nozzle for pushing the tip from the folded state into the unfolded state, when the nozzle is screwed onto the upper chamber of the container.

### Claim 14 (depends on 9)

The container according to claim 9, wherein a first component and a second component are provided, wherein a mixture of the first component and the second component produces a gaseous component increasing an inside gas pressure inside the container.

### Claim 15 (depends on 9)

The container according to claim 9, wherein at least the lower chamber is made from a flexible material.

### Claim 16 (depends on 1)

The nozzle according to claim 1, wherein, if the tip is in the folded state, said volume is enclosed between the connecting part, the intermediate folding ring and the cover plate.
