Lid for Airtight Containers
First Claim
1. A lid for airtight containers, including a lid body, and a plurality of locking flap handles coupled to the lid body so as to be rotatable, each of the locking flap handles having a locking protrusion to be locked to a locking depression formed in an outer edge of an upper end of a container body, whereinthe locking flap handles are connected to the lid body by respective film hinges, each of the film hinge comprising:
- an elastic hinge part continuous with an upper surface of the lid without having a stepped portion, the elastic hinge part being curved outwards at a predetermined curvature; and
a connection part for connecting the elastic hinge part to the locking flap handle, the connection part extending a predetermined length to disperse an impact generated when the locking flap handle is locked to the container body, wherein,when the locking flap handle is locked to the container body, the elastic hinge part is folded around an inner corner, forming a boundary between the elastic hinge part and the lid body, and is elastically brought into contact with an outer surface of the lid body.

Abstract
Disclosed herein is a lid for airtight containers. The lid according to the present invention includes a plurality of locking flap handles, which are coupled to a lid body so as to be rotatable, and each of which has a locking protrusion to be locked to a locking depression formed in the outer edge of the upper end of a container body. The locking flap handles are connected to the lid body by respective film hinges. The film hinge includes an elastic hinge part, which is continuous with the upper surface of the lid without having a stepped portion and is curved outwards at a predetermined curvature, and a connection part, which connects the elastic hinge part to the locking flap handle. The connection part extends a predetermined length to disperse an impact generated when the locking flap handle is locked to the container body. Thus, when the locking flap handle is locked to the container body, the elastic hinge part is folded around an inner corner, which forms a boundary between the elastic hinge part and the lid body, and is elastically brought into contact with the outer surface of the lid body.
