PURPOSE: A both side opening type air fresher is provided to prevent the leakage of aromatic material after both covers are stripped, for improving the emitting amount of aroma. CONSTITUTION: A manufacturing method of a both side opening type air fresher comprises: a step of extrusion(S100) for forming a case which has fixed holes on edge; a step for assembling(S200) the case and a molded jig assembled with the case; a step of implantation(S300) putting liquid aromatic material into the inside of the assembled case; a step of cooling(S400) cooling the liquid aromatic material; a step(S500) of demounting the molded jig after the aromatic material is solidified; a cutting step(S600) cutting the case with constant length; and a sealing step(S700) sealing the both side of the case by attaching thin covers. |
