Description

Technology Field

[0001] The present invention relates to an opening and closing lid for a bucket container. Background Technology

[0002] Generally, cylindrical bucket containers are used in theaters or fast-food restaurants to package cooked food.

[0003] 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.

[0004] However, conventional bucket lids were made of plastic, which resulted in high manufacturing costs and caused environmental problems.

[0005] 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.

[0006] 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.

[0007] However, the conventional bucket container lids described above had the problem of being difficult to use because they were difficult to assemble and disassemble.

[0008] 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. Prior art literature

[0009] Published Utility Model Publication No. 20-2011-0010832 The problem to be solved

[0010] The present invention has been devised to solve the aforementioned problems, and the purpose of the present invention is to provide an opening and closing lid for a bucket container that is formed of paper material and can be easily attached to or detached from a bucket container using connecting wings.

[0011] The problems of the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0012] An opening / closing lid for a bucket container according to an embodiment of the present invention for solving the above problem is coupled to a curling part disposed on the upper part of the bucket container to cover the opening of the bucket container, and is formed of a paper material.

[0013] It may include: a shielding plate supported at the upper end of the curling portion to shield the opening of the bucket container and having a size corresponding to the opening of the bucket container; and connecting wings spaced at equal intervals along the circumferential direction at the edge of the shielding plate and folded downwards toward the shielding plate to be coupled to the curling portion.

[0014] The shielding plate may include at least one heat exhaust hole capable of air flow.

[0015] The above coupling wings may be arranged at least three or more at the edge of the shielding plate.

[0016] Each of the above-mentioned connecting wings may include: a wing body disposed at the edge of the shielding plate and having a portion cut into an arc shape so as to be disposed at the lower part of the curling portion when folded toward the lower part of the shielding plate; and a connecting portion disposed at the cut portion of the wing body and supported by being caught on the curling portion when the wing body is folded.

[0017] The above-mentioned connecting part can be pressed between the curling part and the container body.

[0018] The above-mentioned joint can be formed in an arc shape.

[0019] The above joint may be formed in a wedge shape in which the width gradually decreases toward the end.

[0020] The above-mentioned connecting parts are arranged in multiple numbers and can be multiplely pressed between the curling part and the container body.

[0021] The above-described coupling portion includes: a press-fit area that is pressed between the curling portion and the container body; and a non-press-fit area disposed between the press-fit area and the wing body and exposed to the outside, and the relative ratio of the length of the non-press-fit area to the length of the press-fit area may be 1:2 or more and 1:5 or less. Effects of the invention

[0022] According to an embodiment of the present invention, since the opening and closing lid for a bucket container is formed of paper material, it is easier to mass-produce compared to a plastic lid, thereby reducing manufacturing costs, and it is easy to dispose of, thereby minimizing environmental problems.

[0023] In addition, it can be used safely even when exposed to heat, and can be safely used in a microwave even when attached to a bucket container.

[0024] In addition, the connecting wings arranged along the edges of the shielding plate have a structure that connects to the curling part of the bucket container when folded, making connection and separation easy. This allows the user to easily open and close the lid with one hand while holding the bucket container with the other.

[0025] In addition, since the connecting wings have a structure in which they are connected to the curling part at multiple locations, even if some connections are released, the connection state is maintained in the remaining parts, allowing for high shielding performance.

[0026] In addition, the connecting wings are not only supported by being caught on the curling part, but also have a structure that is pressed into the gap between the curling part and the container body, so the connecting force can be maximized.

[0027] The effects according to the present invention are not limited to those exemplified above, and a wider variety of effects are included within the present invention. Brief explanation of the drawing

[0090] Referring to FIG. 10, the opening / closing lid (100) can be configured to fix the wing body (21) to the container body (C1) when the connecting part (22) is connected to the curling part (C2).

[0091] More specifically, the connecting wing (2) may further include a wing fixing tab (23) that is positioned on the lower side of the wing body (21), folded inward toward the wing body (21), and connected to a wing fixing slit (C11) formed in the container body (C1).

[0092] Accordingly, the opening / closing lid (100) can maximize the fixing force through the connecting part (22) and the wing fixing tab (23).

[0093] FIG. 11 is a schematic diagram showing the connection structure of the connecting wings according to an embodiment of the present invention.

[0094] Referring to FIG. 11, the connecting wings (2) connected to the bucket container (C) can be configured to be connected to each other.

[0095] More specifically, the connecting wing (2) may include a wing connecting tab (24) that is placed on the wing body (21), folded outward from the wing body (21) to be connected to another connecting wing (2) adjacent to one side, and a connecting tab connecting slit (25) to which the wing connecting tab (24) of another connecting wing (2) adjacent to the other side is connected.

[0096] Accordingly, even when an external force is applied to the bucket container (C), the connecting wings (2) can be prevented from being separated or detached from the bucket container (C).

[0097] As such, according to an embodiment of the present invention, the connecting wings (2) arranged along the edge of the shielding plate (1) have a structure that is connected to the curling part (C2) of the bucket container (C) when folded, so that connection and separation are easy, and thereby the user can easily open and close the lid with one hand while holding the bucket container (C) with one hand.

[0098] In addition, since the connecting wings (2) have a structure in which they are connected to the curling part (C2) at multiple locations, even if some connections are released, the connection state is maintained in the remaining parts, allowing for high shielding performance.

[0099] In addition, the connecting wings (2) are not only supported by being caught on the curling part (C2), but also have a structure that is pressed into the gap between the curling part (C2) and the container body (C1), so the connecting force can be maximized.
