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 ).
Claims
exact text as granted — not AI-modified1 - 18 . (canceled)
19 . 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.
20 . The preform coating method according to claim 19 , wherein the coating solution to be deaerated is not degassed in advance.
21 . The preform coating method according to claim 19 , wherein the coating solution is a barrier coating solution having a gas barrier property or a protective coating solution for protecting the barrier coating solution.
22 . The preform coating method according to claim 19 , wherein the coating solution has a viscosity of 25 mPa·s to 10000 mPa·s.
23 . The preform coating method according to claim 22 , wherein the coating solution has a viscosity of 50 mPa·s to 10000 mPa·s.
24 . The preform coating method according to claim 23 , wherein the coating solution has a viscosity of 100 mPa·s to 10000 mPa·s.Join the waitlist — get patent alerts
