Abstract
The present invention provides a preform coating device (5) provided with: a rotating and holding part (9) that holds a preform (1) in a horizontal direction, and rotates the preform (1) about an axis (A) of the preform (1); and a dispenser (6) that has a slot (62) and discharges a coating liquid in a plane form from the slot (62) to the preform (1), wherein the discharge direction of the coating liquid is the direction of the normal to an outer peripheral surface of the preform (1).
Claims24
A preform coating device comprising:
- a rotary holder holding a preform in a horizontal direction and making the preform rotate about an axial line of the preform;
- and
- a dispenser having a slot and discharging a coating solution toward the preform from the slot in a planar state, wherein
- a direction of discharge of the coating solution is a normal line direction of an outer circumferential surface of the preform.
A preform coating method comprising:
- a step of holding a preform in a horizontal direction and making the preform rotate about an axial line of the preform;
- and
- a step of discharging a coating solution toward the rotating preform from a slot of the dispenser in a planar state, wherein
- a direction of discharge of the coating solution is a normal line direction of an outer circumferential surface of the preform.
A preform coating device comprising:
- a rotary holder holding a preform in a horizontal direction and making the preform rotate about an axial line of the preform;
- a conveyor conveying the preform by moving the rotary holder;
- a dispenser discharging a coating solution toward the preform;
- and
- a dryer arranged separated from the dispenser and drying the coating solution coated on the preform, wherein
- the conveyor conveys the preform in a state held in a horizontal direction.
A preform coating method comprising:
- a step of using a deaeration module having hollow fiber membranes to deaerate a coating solution;
- and
- a step of coating the deaerated coating solution on a preform.
