In 1969, when the company was in its seventh year of operation, a contest to design the company emblem was held as an event to celebrate the company reaching 100 million yen in annual turnover. A design created by an aspiring designer from the Nagoya Sales Office was adopted, and made into cloisonné ware.
Since tack labels at the time were increasingly used for sealing printing as labels to seal containers in order to protect their contents, the inside of the exterior modeled after a protective "shield" was divided into three levels representing the sky, sun and sea (blue-red-blue). "IL," the initials of IL Pharma Packaging, were placed inside the sun.
Due to later land readjustment, IL Pharma Packaging's address is inside Mitsui, Ichinomiya, but at the time the area was known as Tanyo-cho Mitsui, Ichinomiya. Tanyo, rendered as "丹陽" in Chinese characters, carries the meanings of morning (red) sun and a day of true devotion. For this reason, the letters "IL" are engraved inside the red sun.
