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).
Claims11
A preform coating device having a horizontal direction normal to gravity, the preform coating device comprising:
- a rotary holder configured to:
- hold a preform comprised of an opening part, a hollow cylindrical body part adjoining the opening part, and a bottom part closing one end of the hollow cylindrical body part and having an axial line in the horizontal direction centered within the hollow cylindrical body part, and
- rotate the preform about the axial line, wherein the rotary holder grips the opening part of the preform and makes the preform rotate while a dispenser is discharging a coating solution;
- a preform support positioned, in a vertical direction, under a bottom part side end of the hollow cylindrical body part to support the bottom part side end of the hollow cylindrical body part of the preform while the dispenser is discharging the coating solution;
- and
- the dispenser having a slot and being configured to discharge the 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 device having a horizontal direction normal to gravity, the preform coating device comprising:
- a rotary holder configured to:
- hold a preform comprised of an opening part, a hollow cylindrical body part adjoining the opening part, and a bottom part closing one end of the hollow cylindrical body part and having an axial line in the horizontal direction centered within the hollow cylindrical body part, and
- rotate the preform about the axial line, wherein the rotary holder grips the opening part of the preform and makes the preform rotate while a dispenser is discharging a coating solution;
- a preform support positioned, in a vertical direction, under a bottom part side end of the hollow cylindrical body part to support the bottom part side end of the hollow cylindrical body part of the preform while the dispenser is discharging the coating solution;
- a conveyor conveying the preform by moving the rotary holder;
- the dispenser discharging the 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 the horizontal direction.
