The effect of the blocking hole of raw material flow

Hanacobi is a professional manufacturer of functional storage containers which has put in continuous efforts in research and development to produce what LOCK&LOCK is today.

The difference between the generic storage container and the Lock&Lock container can be said to be the effect of the blocking hole of raw material flow, which proves its excellence in quality.

Blocking hole of raw material flow
¡æa. Weld line does not form around the hinge area
¡æb. Does not damage the lid and can use the product semi-permanently

The hinge is designed short-in-length in order to prevent any stiffness when opening & closing.

Reduced the residual stress coming from bending the hinge and was able to technically strengthen the part for a longer lasting life.

  Vocabulary
 
Hinge : Where the locking latch folds
Blocking hole of raw material flow : Hole in the middle along side the hinge between the two rectangular holes that lock
Weld line : Fine lines produced where two raw material flow of plastic resin meet when shaping of the container, liable to cause damage in the container when opening & closing the lid.
