Document Type and Number:
WIPO Patent Application WO/2018/008894
Kind Code:
A1
Abstract:
Disclosed is a vacuum-sealed container wherein a large negative pressure is applied inside the container compared with a conventional one without using a pump such that a high degree of vacuum can be maintained, making it possible to store food for a long time; the container can be sealed without using a packing such that, by dispensing with the packing, the manufacturing cost can be reduced; the structure of coupling between the container body and the lid is not complicated such that the same is easy to make, and alien substances can be easily removed; and there is no such inconvenience as having to fit a packing, which is released during use, again. The vacuum-sealed container comprises: a container body having a lid coupling groove formed along the periphery of the upper end portion of an opening and arranged along a closed path; a lid body formed to be convex upward using an elastic material, the lid body having a sealing portion formed thereon such that the same is inserted into the lid coupling groove along the periphery thereof so as to seal the inside of the container body; and a valve installed on the lid body so as to provide a passage, through which air inside the container body is discharged to the outside, and so as to expose/cover the passage.
