PURPOSE: A liquid injector installed on a heat insulation pack is provided to prevent liquid contained in the pack from leaking due pressure. CONSTITUTION: A liquid injector (100) installed on a heat insulation pack includes two films (10) which are installed at a part of the heat insulation pack and allow contents to be injected into the heat insulation pack. Basic attachment lines (11) are attached to the right and left of the injector. Auxiliary attachment lines are formed around the basic attachment lines with an interval. A back flow prevention attachment line (13) is formed on the lower part of the auxiliary attachment lines to prevent the back flow of contents. When internal pressure increases, the back flow prevention attachment line endures the pressure or auxiliary attachment lines are broken and liquid flows into the pack.
