Description

Technical Field

[0001] The utility model belongs to the field of packaging boxes, and specifically relates to a kraft paper packaging box. Background Art

[0002] Kraft paper is made of high-strength pure wood pulp fiber, and has the advantages of high packaging strength and strong tear resistance. At present, kraft paper has been widely used in the production of packaging boxes. Due to its preparation process, kraft paper has many micropores on its surface, and the surface is uneven and not smooth. If the code (such as the traceability code) is directly sprayed on the surface of kraft paper, the ink will "diffuse" after the code is sprayed, causing the code to be blurred and affecting normal use. Therefore, most of the kraft paper packaging boxes in the existing technology do not spray codes, which seriously affects the anti-counterfeiting effect of kraft paper packaging boxes.

[0003] In the prior art, for the convenience of use, the corrugated paper, kraft paper and other high-strength packaging boxes are generally pre-set with a handle integrally formed with the box body on the box body, and an easy-tear seam or an easy-tear strip is provided between the handle and the box body. When in use, the handle is opened along the easy-tear seam or the easy-tear seam and bent upward for use. For example, the utility model patent technology of packaging box with the announcement number CN208882335U authorized by the China Patent Office on May 21, 2019, the packaging box includes a box body and an upper cover plate, wherein the upper cover plate is formed with at least one set of handle plates and tear strips; a handle hole is formed on the handle plate, and the first side of the handle plate is flexibly connected to the upper cover plate; the second side of the handle plate is connected to the upper cover plate through the tear strip; wherein the first side is a straight edge. The packaging box of the above structure has a handle structure integrally formed with the upper cover plate, and no additional material is required to form the handle, so it has the advantage of low manufacturing cost, and the handle structure will not cause adverse effects on logistics stacking.

[0004] However, the packaging box with the above structure also has certain usage defects. After the handle is opened along the easy-tear seam or the easy-tear seam and used as a handle, a hole of corresponding shape will be formed on the upper cover plate. When there are still items left in the packaging box, consumers still hope that the box body can be simply closed. Since the handle plate cannot be reset after opening, the packaging box cannot be simply closed again. Utility Model Content

[0005] The utility model aims to provide a kraft paper packaging box, wherein a rotatable long strip or elliptical limiting plate is provided at the bottom of the handle integrally formed with the upper cover plate, and the limiting plate can be rotated to realize simple closure of the box body again after the handle is opened, and at the same time, a white ink layer is first provided at the coding location on the surface of the kraft paper, and then coding is performed, so that the coding on the kraft paper packaging box is clear.

[0006] The utility model is realized by the following technical solutions:

[0007] That is, a kraft paper packaging box, including a box body, an upper cover plate on the box body, a group of handle plates symmetrically arranged on the upper cover plate, and an easy-tear seam between the edge of the handle plate and the upper cover plate. It is characterized in that the lower end surface of the handle plate is provided with at least one long strip or elliptical limiting plate, the middle part of the limiting plate is connected to the handle plate through a rotating shaft, the width of the limiting plate is smaller than the width of the handle plate, and the length is greater than the width of the handle plate.

[0008] The limiting plate of the utility model is installed on the lower end surface of the handle plate through a rotating shaft. The limiting plate is in a strip or elliptical shape. By rotating, the limiting plate can be completely hidden in the lower end surface of the handle plate or partially protrude from the limiting plate.

[0009] After the handle plate is opened and used as a handle, when the packaging box needs to be simply sealed again, the handle plate is flipped to the hole, and the shaft is rotated so that the limiting plate partially protrudes from the handle plate and extends to the bottom of the upper cover plate to prevent the handle plate from tilting upward, thereby achieving a simple seal of the packaging box.

[0010] When the handle plate needs to be used as a handle again, the rotating shaft is rotated so that the limiting plate is completely hidden in the lower end surface of the handle plate, and the handle plate is flipped upwards.

[0011] The easy-tear seam of the utility model is also called an easy-tear line / cut line. The handle plate can be easily separated from the upper cover plate through the easy-tear seam, and the two handle plates are turned upward along the fold line to form a handle.

[0012] Furthermore, the box body of the utility model is provided with a coding area, and the box body at the coding layer is provided with a white ink layer and a coding layer from the inside to the outside.

[0013] The white ink layer of the utility model is common white ink, which is printed or sprayed on the surface of the box body to fill the micropores on the surface of the kraft paper, and the code is sprayed on the white ink layer, and the ink will not spread and will not cause blurring of the code.

[0014] As the above solution, the coding layer is exposed on the outer side of the box body.

[0015] Furthermore, the bottom surface of the limiting plate of the utility model is provided with a coding area, and the box body at the coding layer is provided with a white ink layer and a coding layer from the inside to the outside.

[0016] As the above solution, the coding layer is hidden inside the box body before the handle is opened. The coding can only be seen when the handle is opened, and the handle cannot be restored. The combination of the two enhances the anti-counterfeiting effect.

[0017] Furthermore, the cross section of the rotating shaft of the utility model is an I-shaped one, and a straight countersunk groove is provided on the upper end surface of the rotating shaft.

[0018] The upper end of the rotating shaft of the utility model is provided with a slotted countersunk groove, and the rotating shaft can be easily rotated by using a fingernail or other sheet-like hard objects, thereby driving the limit plate to rotate.

[0019] The utility model has the advantages of reasonable structure and convenient use. When using the packaging box of the utility model, the handle plate can still be easily sealed after being opened, and the packaging box is convenient to use. The utility model provides a white ink layer on the surface of the kraft paper, so that the inkjet code can be clearly displayed on the kraft paper packaging box, thereby improving the anti-counterfeiting effect of the kraft paper packaging box.
