Sealant device for sealing a vehicle tyre, puncture repair kit with such a sealant device and a method for producing such a sealant device

1 . A sealant device for a sealant for sealing a vehicle tire, comprising:

a housing for containing the sealant, the housing including a housing section and closure unit operably coupled to the housing section, the closure unit having first and second openings, wherein the first opening is configured as an air inlet for permitting air into the housing, and the second opening is configured as a sealant outlet for permitting the sealant to exit the housing,

a tube having an internal passage, the tube being arranged to fluidly connect its internal passage with the first opening of the closure unit, wherein the tube extends into the housing and has a tube outlet within the housing through which air can flow from the first opening through the internal passage and into the housing,

a first sealing element configured to close air flow through the tube outlet when in a closed state, wherein the first sealing element is movable to an open state in response to air pressure via the first opening which thereby opens air flow through the tube outlet and permits air to flow from the first opening through the internal passage and into the housing, and

a second sealing element that closes the second opening,

a hose connector at the second opening for fluidly connecting hose to the device, the hose connector having an integrated cutting device configured to cut the second sealing element in response to insertion of the hose;

wherein the second sealing element is configured as a destructible closure that is fixed in relation to the second opening and which is configured to only permit opening of the second opening upon destruction of the second sealing element via cutting with the integrated cutting device.

2 . The device as claimed in claim 1 , wherein the tube outlet is located at an axial end of the tube, wherein the first sealing element is arranged at the tube outlet and is formed such that it can be detached from the end of the tube when moved into the open state.

3 . The device as claimed in claim 2 , wherein the tube extends from the first opening as far as the rear third of the housing.

4 . The device as claimed in claim 1 , wherein the first opening can be connected to a compressor.

5 . The device as claimed in claim 1 , wherein the second opening can be indirectly connected to a vehicle valve.

6 . The device as claimed in claim 1 , wherein the second opening is arranged substantially perpendicularly with respect to the first opening.

7 . The device as claimed in claim 1 , wherein the closure unit is not detachably connected to the housing section.

8 . The device as claimed in claim 1 , wherein the connection between the closure unit and the housing section is connected by means of ultrasound or snap closure.

9 . A puncture repair kit, comprising the sealant device as claimed in claim 1 and a pressure source.

10 . A method for producing the sealant device as claimed in claim 1 , comprising the steps:

manufacturing the housing section by blow molding or injection molding,

manufacturing the closure unit with the first and second openings by injection molding, and

connecting the housing section to the closure unit to form the housing of the sealant device by ultrasound or via a snap-on closure or via a bayonet closure.

11 . The device as claimed in claim 1 , wherein the first sealing element is a plug at the tube outlet, the plug having a seat that engages an end face of the tube outlet when in the closed state such that the plug is movably detachable from the tube outlet only in the flow direction of incoming air via the first opening.

12 . The device as claimed in claim 1 , wherein the second sealing element is a foil seal attached to an end face of the second opening.

13 . A sealant device for a sealant for sealing a vehicle tire, comprising:

a housing for containing the sealant,

a first opening configured as an air inlet that can permit air into the housing, and

a second opening configured as a sealant outlet that can permit the sealant to exit the housing,

a tube having an internal passage, the tube being arranged to fluidly connect the internal passage with the first opening, wherein the tube extends into the housing and has a tube outlet within the housing through which air can flow from the first opening through the internal passage and into the housing,

a first sealing element configured to close the tube outlet when in a closed state, wherein the first sealing element is movable to an open state in response to air pressure via the first opening which thereby opens the tube outlet and permits air to flow from the first opening through the internal passage and into the housing, and

a second sealing element that closes the second opening,

a hose connector at the second opening for fluidly connecting hose to the device, the hose connector having an integrated cutting device configured to cut the second sealing element in response to insertion of the hose;

wherein the second sealing element is configured as a destructible closure that is fixed in relation to the second opening and which is configured to only permit opening of the second opening upon destruction of the second sealing element via cutting with the integrated cutting device.
