 Introduction of our developed products,「APK Cap」「Rakka-Less」「BG Twin Cap」.

​ ◆APK Cap

It is a representative product of Hirohama which solved "capping damage to cap" and "setting damage to neck".We formerly sold AP Cap, but now we offer APK Cap for B40 Cap and B50 Cap after the improvement.We have already finished the development for B70 Cap.

​ ◆Rakka-Less

B type Rakka-Less Cap is a industry's first product which have projections to prevent packing from falling when cans are opened.

Most of packings drop from former cap when we open it and it causes dirty of hands or packing.This product solved those problems.


Former Cap


​◆BG Twin Cap

*It is a new version of popular BR Ring Cap.

*We raise sealing function by curling the bottom of protector.

*We can open it easily because protector is split from the surface of cut.

*It is suitable for food can because of high safety.

Former Twin Cap has some problems in terms of sealing function.

For example, it happened that the caps easily come off because of contacting with bottom of round cans during transportation or use of drivers.

BG Twin Cap was produced to improve safety by curling the bottom of protector.
We can prevent cap from being removed by driver.

It is also used for export can because of high air-tightness.

Please refer to a manual to open caps correctly.
