Document Type and Number:
WIPO Patent Application WO/2013/117060
Kind Code:
A1
Abstract:
Disclosed are a silica gel glass lid and packing container. The silica gel glass lid (10) comprises a lid plate (11) and a lid flange (12) protruding on a side face of the lid plate (11). The lid flange (12) is close to the edge of the lid plate (11) and is provided along the periphery of the lid plate (11) to form a seal. A silica gel rim (13) protrudes from the side edge of the lid flange (12) close to the edge of the lid plate (11). The silica gel rim (13) is securely connected to the lid flange (12) by means of a silica gel connector (14). The silica gel rim (13) is moulded as one piece with the silica gel connector (14). A through-hole (16) is provided on the lid plate (11) in a region enclosed by the lid flange (12), and an air extraction sealing device (15) is installed at the through-hole (16). When the silica gel glass lid is covering the container body, the silica gel glass lid seals the container body and residual air in the holding space formed between the silica gel glass lid and the container body can be vented by the air extraction sealing device. Retightening the air extraction sealing device forms a sealed holding space. Glass can be used to manufacture the container body of the packing container, an excellent seal can be achieved between the silica gel glass lid and the container body, while the invention is practical and simple and costs are low.
