- the synthetic keg container 15 is exposed at room temperature for a predetermined time, for example, for 15 to 40 minutes to perform a cooling or cooling process.
- the reason for cooling or cooling as described above is to lower the surface temperature of the synthetic keg container 15 to 35° C. or less, and the synthetic keg container 15 is transferred to a cooling conveyor (not shown) at a constant temperature at room temperature.
- the stopper member 11 is coupled to the inlet/outlet connector 3 formed in the upper center of the synthetic keg container 15 that has passed the inspection, and is inserted into the case member 7, and then the upper head The part 10 is coupled to the upper end of the case member 7 to finally complete the draft beer container 5 .
- the viewer window 6 is formed on one side of the case member 7, and the synthetic keg container 15 formed by coupling the winding member 2 to the liner body 1 is composed of a composite material and has a Since it is transparent enough to check the contents, when the viewer window 6 is checked, the remaining amount of draft beer can be checked. Therefore, when draft beer falls on the draft beer container 5 through the viewer window 6 , the user can easily prepare another draft beer container 5 .
- a draft beer keg container is manufactured by winding a wire mixed with glass fiber and resin on the outside of the liner structure by a filament winding method, so that the draft beer keg container is composed of a composite material, so draft beer made of stainless steel It is light in weight compared to keg containers, so transport is easy and internal corrosion does not occur, so the freshness of the draft beer stored inside can be maintained at a constant level.
- the draft beer container according to the present disclosure is composed of a composite material, heat conduction is very low, so that external heat has little effect on the inside of the draft beer container, so it is easy to preserve the contents contained in the draft beer container.
- the draft beer container of the present disclosure has good transparency because it is made of a composite material, it is possible to easily check the remaining amount of the internal contents through the remaining amount confirmation window provided in the outer case, and it is lighter and less expensive than the stainless steel draft beer container. can be reduced and the lifespan can be extended.
