Backpack type packaging box}

The present invention relates to a backpack-type packaging box, and more specifically, to a box body whose bottom is sealed by the bottom of the box and whose open upper part is opened and closed by a box cover, and shoulder straps connected as a pair to the rear side plate of the box body. A structure in which the cover plate is folded and rotated based on the top of the rear side plate, and the box cover is opened and closed through latching and unlatching using the tension force of the tension locking part of the opening and closing piece provided on the top of the front side plate and the locking hole of the inner wall plate. By applying it, the opening and closing of the cover covering the open top of the box body can be easily done through a tension locking and releasing structure, and at the same time, it can be easily carried by carrying it on both shoulders as a backpack type through a pair of shoulder straps. This is about a backpack-type packaging box that allows

Generally, the packaging box that protects and displays the product is placed in a separate bag so that the user can conveniently carry it.

However, in this case, there is a problem that a separate bag must be prepared to put the packaging box in, and various bags must be prepared according to the size of the packaging box.

Therefore, in order to solve this problem, a variety of technologies are being proposed that include a packaging box with a string that the user can carry.

First, the prior art related to this technology includes Public Utility Model No. 20-2011-0004063, 『Packaging Box Equipped with a Mirror for Use as a Bag』, which forms a receiving space with only the upper surface open inside to store gifts. A main body, a cover that is rotatably connected to one corner of the open upper surface of the main body to open and close the open upper surface, and is foldable installed on one side of the lower surface of the cover, so that when the cover closes the open upper surface, A mirror that unfolds when the folded and opened upper surface is opened to keep the cover open from the main body, and is detachable to form a handle that can be held by hand by wrapping across the main body and the cover to secure the cover from opening from the main body. We present a packaging box that doubles as a bag and has a mirror made of ribbon tape.

However, the prior art is to form a handle by adjusting the length of the ribbon tape fixed to the packaging box. The handle can easily fall off, and as it is fixed using male and female snap buttons, a separate post-processing process for button insertion is required. There is a problem that more is needed.

In addition, there is a prior art, Publication Patent No. 10-2010-0041306, “Assembly structure of a bag-type paper box,” which is a main plate consisting of a front plate, a back plate, a bottom plate, and a lid plate on a single plate, and the top plate is formed from the bottom plate, respectively. It is made up of three plates, including the left and right side plates assembled between the front plate, which stands and folds at a right angle, and the two ends of the back plate, and is easy to separate except for one place at the upper corner of the front plate to maintain the connection ecology of the front plate and each side plate. We are presenting a bag-type paper prefabricated box that boasts a neat appearance because the assembly binding elements (rivels) are not exposed at all.

However, the above prior art involves assembling plates composed of a plurality of powders using ribbeds, cap nuts, etc., and each powder can be separated by weight depending on the product being stored, and each powder is manufactured separately, thereby reducing the manufacturing process. There is a problem that this cannot be unified.

Furthermore, there is a prior art, Public Utility Model No. 20-2007-0000669, 『Gift Box with Handle Strap Attached』, which involves decorating the outside of the gift box with a ribbon and then acting as a box handle on the inner and outer cylinder joints. You can carry the box by connecting the ribbon so that you can carry it around. If you remove the ribbon decoration attached to the gift box in the form of a handle and lift it without having to tie it with a separate packing string or attach it with tape, the box lid will not open, making gift packaging even better. We are presenting a gift box that is easy to make.

However, the prior art is a technique of simply combining a handle with a general packaging box, and there is a problem in that the packaging box can be easily opened because a separate device for fixing the lid and the body is not provided.

Furthermore, there is Public Utility Model No. 20-2010-0012894, 『String Handle Assembly Box』, in which the prior art is composed of paper fabric as an integrated piece based on the bottom surface, and fastening holes are formed on the left and right sides where the wings are located. The front and back sides without wings are perforated and fastened with strings of various materials and shapes. Even when dismantled, all sides are folded up and down based on the floor to minimize the volume as much as the floor for movement and storage. We present this simple, convenient to use, and cleanly reusable string handle assembly box.

However, the prior art has a problem in that it is difficult for users to easily carry the product because the top is open, making it difficult to store the product.

Moreover, the packaging boxes according to the prior art as described above had a problem in that the cover portion could not be easily opened and closed, and at the same time, it was not easy to carry them, such as by carrying them on the shoulder.

Therefore, there is a need for research and development on a backpack-type packaging box that allows easy opening and closing of the cover that covers the open top of the box body, and at the same time allows for easy carrying by carrying it on both shoulders as a backpack type. am.
