Abstract

A lid for opening and closing a bucket container is disclosed, which is formed of paper material and can be easily attached to or detached from the bucket container using connecting wings. A lid for opening and closing a bucket container is formed of paper material and is coupled to a curling portion positioned at the top of the bucket container to shield the opening of the bucket container. It includes a shielding plate having a size corresponding to the opening of the bucket container, which is supported at the upper end of the curling portion to shield the opening of the bucket container, and coupling wings that are spaced at equal intervals along the circumferential direction along the edge of the shielding plate and are folded downwards from the shielding plate to be coupled to the curling portion.

Description

Opening and closing lid for bucket container The present invention relates to an opening and closing lid for a bucket container. Generally, cylindrical bucket containers are used in theaters or fast-food restaurants to package cooked food. At this time, a lid is attached to the top of the bucket container to prevent the contents contained in the bucket container from spilling and to maintain heat. However, conventional bucket lids were made of plastic, which resulted in high manufacturing costs and caused environmental problems. Furthermore, conventional lids for bucket containers were vulnerable to heat, causing deformation when exposed to hot contents or used in a microwave, as well as generating harmful substances. Meanwhile, conventional bucket lids are formed as a single-piece structure with a fixed shape through plastic injection molding; consequently, they are designed to be secured to the bucket only by applying pressure along the rim while placed on top of the bucket. Additionally, when separating the lid from the bucket, it must be detached sequentially by lifting the bottom section from one side. However, the conventional bucket container lids described above had the problem of being difficult to use because they were difficult to assemble and disassemble. In particular, there was a problem in that it was difficult to use because it was hard to attach or detach the lid from the bucket container with the other hand while holding the bucket container with one hand. FIG. 1 is a diagram showing the state in which an opening/closing lid according to an embodiment of the present invention is coupled to a bucket container. FIG. 2 is a plan view showing an opening and closing lid according to an embodiment of the present invention. FIG. 3 is a plan view showing a modified embodiment of a heat exhaust hole according to an embodiment of the present invention. Figure 4 is an enlarged view of section "A" of Figure 1.
