Title:
COVERING ASSEMBLY AND COVER THEREOF, AND COOKING UTENSIL
Document Type and Number:
WIPO Patent Application WO/2019/233139
Kind Code:
A1
Abstract:
The present application provides a covering assembly and a cover thereof, and a cooking utensil. The cover comprises: a glass layer; a polystyrene layer formed on the surface of the glass layer towards a hollow cavity by means of injection molding and forming an integrated structure with the glass layer; and a polyethylene layer formed on the polystyrene layer by means of injection molding and at least covering a region corresponding to the polystyrene layer and an opening of the hollow cavity so that the cover is hermetically matched with the hollow cavity. The cover adopts a structure of forming polystyrene and polyethylene on the glass by means of secondary injection molding, which solves the problem in the prior art that the glass and an internal support are easy to curl up or even fall off, and also solves the sealing problem of the cooking utensil such as a storage bin and an electric cooker. Moreover, compared with the previous double-sided gluing mode, the present application greatly improves the process efficiency of the cover and also solves the quality problem caused by gluing.
