Abstract
Description
Technical Field
[0001] The invention relates to a blank for forming a packaging box, in particular to a packaging box with a double-layer carrying handle function. Background Art
[0002] In the packaging industry, as people's awareness of environmental protection is awakened and countries pay more attention to the damage of plastic products to the ecology, de-plasticization has become the focus of this field. How to design a de-plasticization packaging box with convenient carrying and sturdy handle function is very important.
[0003] Nowadays, although a variety of all-paper packaging boxes have been developed, they are often equipped with a plastic handle for easy carrying. This method cannot achieve the requirement of de-plasticization. Alternatively, holes are directly dug in the packaging box to serve as handles. This method not only damages the appearance of the packaging box but also makes it easy for foreign objects to enter and contaminate the packaged items. Another design is a multi-piece combination type, in which a packaging box body component is combined with a handle component. Although this method meets the requirements of environmental protection, it increases material costs.
[0004] Based on cost and environmental considerations, the packaging box or carrying device used for this type of packaging must be formed with the least amount of material as possible, and waste must be reduced to a minimum, which is an important issue in the packaging box field. Summary of the invention
[0005] In view of this, the present invention provides a packaging box with a double-layer handle, wherein the integrally formed blank has a packaging box structure that can form a carrying handle, and the handle is easy to unfold when in use and easy to store when not in use.
[0006] The present invention discloses a double-layer hand-held packaging box, which is formed by folding a packaging box blank sheet, and comprises: a first box surface, and a plurality of side surfaces are extended from each side of the first box surface, wherein a first side surface is connected to a second box surface at the opposite side of the first box surface, and a first auxiliary sheet is extended from each of the remaining two corresponding sides of the first side surface; the second box surface is connected to a buckle sheet at the opposite side of the first side surface, and a second auxiliary sheet is extended from each of the remaining two corresponding sides of the second box surface; a third auxiliary sheet is extended from each of the buckle sheet to the opposite sides; the first box surface is connected to the opposite side of the first side surface, and a second auxiliary sheet is extended from each of the remaining two corresponding sides of the second box surface; A second side surface is connected, and the second side surface is connected to a first inner wall at the opposite side of the box surface; a fourth auxiliary piece is extended from the remaining two corresponding sides of the second side surface; the remaining two corresponding sides of the first box surface are a third side surface and a fourth side surface, and a second inner wall and a third inner wall are extended in the direction away from the box surface; the second inner wall and the third inner wall each extend a handle fixing portion on a side close to the second side surface, and then extend a handle holding portion and a handle movable portion; and the second side surface and the buckle piece each have a handle hole at the corresponding position.
[0007] When in use, the double-layer handle grip of the packaging box with double-layer handles of the present invention arches out the handle hole into an arc shape for carrying. The double-layer handle grip structure can enhance the strength of the handle and increase the load-bearing capacity of the packaging box.
[0008] In one embodiment of the present invention, after the handle is used, the gripping portion of the handle can be pushed into storage in the direction of an indication mark, and can be reused next time. BRIEF DESCRIPTION OF THE DRAWINGS
