Title:
SEALING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/198166
Kind Code:
A1
Abstract:
In this sealing method, two CIPGs with different viscosities are used in order to seal between a lower case (1) and an upper case (2). A first liquid sealing material (11) with a higher viscosity is applied with a dispenser in a line onto a sealing surface (5) of the lower case (1), and is cured with UV irradiation. The first liquid sealing material (11) forms a continuous loop, and a coating start section (11a) and a coating end section (11b) adjacent on the sealing surface (5) configure an overlap section (11c). On the overlap section (11c), a second liquid sealing material (12) with relatively low viscosity is coated along a groove (13) between a bead on the coating start section (11a) and a bead on the coating end section (11b). This suppresses reductions in sealing performance at the overlap section (11c).
