1. A sealing device comprising:
- a liquid agent container in which a sealing agent is contained, the liquid agent container having a discharge aperture at a bottom portion thereof for discharging the sealing agent, and the discharge aperture being sealed by a seal member;
a compressor for applying pressure to the sealing agent and supplying the sealing agent into a pneumatic tire;
an injection unit disposed further down than the discharge aperture, the injection unit opening the seal member by the liquid agent container moving axially downward in a translational motion relative to the compressor and relative to the injection unit, letting the sealing agent flow out from the discharge aperture.

Abstract
Provide a sealing device with which simple and reliable operation can be performed. When stored, a liquid agent container, in which a sealing agent is contained, is temporarily held above a injection unit. When the liquid agent container is forcibly pressed downward in use, the upper end of a pressing jig penetrates through an aluminum seal into the container, and the sealing agent flows out to a compressor unit is activated and compressed air is supplied into the liquid agent container to place the pressurized sealing agent into a pneumatic tire through a joint hose.

13. A sealing device, comprising:
-
a casing; a liquid agent container in which a sealing agent is contained, the liquid agent container having a discharge aperture which is sealed by a seal member; a compressor unit disposed on the casing and which applies air to the liquid agent container; an injection unit connected to the discharge aperture, wherein the injection unit opens the seal member when the liquid agent container moves downward relative to the casing, and the sealing agent discharges from the discharge aperture; and a projection projecting upwardly from the casing and which supports the liquid agent container, and wherein a flange comprising a bridging portion is movable with the liquid agent container, and wherein the projection breaks the bridging portion in response to a downward force applied to the liquid agent container.
