Title:
METHOD FOR MANUFACTURING DISPOSABLE CONTAINER PAPER LID AND DISPOSABLE CONTAINER PAPER LID
Document Type and Number:
WIPO Patent Application WO/2020/141673
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a disposable container paper lid and a disposable container paper lid, and the objective of the present invention is to form a paper lid capable of covering a disposable container through paper having a predetermined thickness, and to improve the edge structure of the paper lid, thereby more firmly maintaining contact with a curled portion (reinforcing rim) of the disposable container and remarkably increasing strength. To this end, according to the method for manufacturing a disposable container paper lid and the disposable container paper lid, of the present invention, a coupling part (220) formed at the edge of the paper lid (200) comprises: a wall surface contact part (221) formed to have a U-shaped cross section shape at the edge of a cover part (210), thereby coming in close contact with the inner surface of the upper end of a wall surface (110) of the disposable container (100); and a rim contact part (222) formed to have an inverted U-shaped cross section shape at the upper end of the edge of the wall surface contact part (221), thereby encompassing the reinforcing rim (111) of the disposable container (100). Therefore, when the paper lid (200) is put on the disposable container (100), the wall surface contact part (222) comes in close contact with the inner surface of the upper end of the wall surface (110) of the disposable container (100) and, simultaneously, the rim contact part (222) encompasses the reinforcing rim (111) of the disposable container (100) again so that the opened upper part of the disposable container (100) can be reliably covered.
