1. Field of the Invention
The present invention relates to a packaging container, and more particularly to a container that is foldable to pack electric appliances, and includes a grip portion to carry the packed product.
2. Description of the Related Art
Generally, large and heavy electric appliances, such as washing machines or refrigerators, once produced, are wrapped in a packaging container to prevent a main body thereof from being broken, and are then conveyed to a container ship or a storage facility.
Such a packaging container has a hexahedral cube shape, of which a lower surface is opened, thus covering upper and side surfaces of a targeted electric appliance. A cushion member for buffering the bottom of the electric appliance is located on the opened lower surface of the packaging container.
Since it is difficult to convey electric appliances that are large in volume and heavy in weight, using manpower, the large and heavy electric appliances are wrapped in a packaging container, and are then conveyed by a conventional forklift, or a similar device. Some conventional packaging containers are conveyed by allowing a fork of the forklift to suspend an upper part of a side surface of the packaging containers, thereby causing electric appliances accommodated by the packaging containers to be conveyed.
A band is wound on the outer surface of each of the above packaging containers so that the packaging container containing the electric appliance and the cushion member can be lifted, and a grip portion is formed at the upper part of the side surface of the packaging container so that the fork of the forklift can be hung on the grip portion.
The above-described packaging container comprises a main body, provided with opened upper and lower surfaces, for surrounding side surfaces of an electric appliance, and a cover, attached to the opened upper surface, for covering an upper surface of the electric appliance and upper ends of the side surfaces of the main body. The main body and the cover are separately manufactured as folding cardboard, which is properly cut out and processed. The main body and the cover are then interconnected when the electric appliance is wrapped in the packaging container, thereby forming a hexahedral cube shape provided with an opened lower surface.
Since the main body and the cover of the conventional packaging container are separately manufactured, the above conventional packaging container causes difficulty for manufacturers, and requires an additional operation of interconnecting the main body and the cover when a product is wrapped in the packaging container, thereby causing difficulty when wrapping the product.
Therefore, an aspect of the invention is to provide a packaging container that achieves an easy packaging procedure of large and heavy products, such as electric appliances, conveyed by a forklift.
It is another aspect of the present invention to provide a packaging container that is simply manufactured.

For reference, the present invention will be exemplarily applied to a washing machine.
A packaging container 10 in accordance with an embodiment of the present invention serves to wrap large and heavy products such as electric appliances, including a washing machine and a refrigerator, and is made of bendable multilayered Dec. 22, 2004 cardboard. As is shown in
The side cover portion 20 includes a plurality of side covers 21, 22, 23 and 24 integrally formed and bent for covering each of the four side surfaces of the washing machine 1, i.e., a first side cover 21, a second side cover 22, a third side cover 23 and a fourth side cover 24.
The side cover portion 20 further includes a connecting portion 25 positioned at one edge of the fourth side cover 24, distant from the third side cover 23, and folded and connected with one edge of the first side cover 21 under the condition that the side cover portion 20 is folded so that the first, second, third and fourth covers 21, 22, 23 and 24 respectively surround the four side surfaces of the washing machine, and folds 26 positioned between the neighboring side covers 21, 22, 23 and 24 and between the fourth side covers 24 and the connecting portion 25, so that the first, second, third and fourth covers 21, 22, 23 and 24 and the connecting portion 25 are easily folded against one another.
The upper cover portion 30 includes a plurality of upper covers 31, 32, 33 and 34, i.e., a first upper cover 31, a second upper cover 32, a third upper cover 33 and a fourth upper cover 34, respectively extended integrally from the first, second, third and fourth side covers 21, 22, 23 and 24 and bent to cover the upper surface of the washing machine 1. The upper cover portion 30 further includes folds 35 formed between each of the upper covers 31, 32, 33 and 34 and the corresponding one of the side covers 21, 22, 23 and 24 so that the upper covers 31, 32, 33 and 34 and the side covers 21, 22, 23 and 24 are easily folded against one another. According to one embodiment, the upper covers 31, 32, 33 and 34 are designed such that each of the upper covers 31, 32, 33 and 34 covers half of the whole upper surface of the washing machine 1 under the condition that the packaging container is folded.
The packaging container 10 further comprises a grip portion 40 extended integrally from the packaging portion so that the packaging portion is lifted up using the grip portion 40. The grip portion 40, under the condition that the washing machine 1 is wrapped in the packaging container 10, is caught by a fork of a forklift, thereby allowing the packaging container 10 containing the washing machine 1 to be conveyed.
More specifically, the grip portion 40 includes a plurality of bending portions 41 and 42, which are positioned between the second side cover 22 and the second upper cover 32, are fixedly bent toward an outer surface of the second side cover 22, and integrally connect the second side cover 22 and the second upper cover 32. Accordingly, as is shown in
