Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a machine-formed, moisture-retaining, and tamper-proof packaging box. Background Technology

[0002] Chinese Patent Publication No. CN220702036U, published on April 2, 2024, discloses a novel humidified cigarette box with a unique opening structure. The box includes a main body with an opening at the top after packaging. This opening is a folded section cut from the cigarette box, with its upper edge connected to the main body and the other three sides folding upwards. The folded opening forms a window on the main body, matching its shape. Adhesive labels are affixed to the inner surface of the main body and the window. When sealing, the edges of the opening are adhered to the adhesive labels. To open, the opening is peeled off from the outer surface of the main body. This invention utilizes adhesive labels on the inner surface of the cigarette box, preserving its overall color and texture without requiring surface printing, thus reducing manufacturing costs. The reduced thickness and contact area also minimize contact with creases, reducing the impact on crease stiffness and increasing durability. The existing technology has the following drawback: cigarettes need to be stored at a relatively ideal humidity level to maintain their quality and aroma, such as between 60% and 70% relative humidity. Excessive humidity can lead to mold growth, while insufficient humidity can cause the tobacco to become dry and brittle. Given this, the existing technology only uses adhesive tape to seal the opening, which is insufficient to guarantee proper moisture retention. Therefore, improvement is urgently needed.

[0021] Please refer to Figure 1-4 According to the first embodiment shown, this utility model provides a machine-formed moisturizing and tamper-proof packaging box, including a box body. The upper part of the box body has an outward-turned surface 21 formed by cutting and tearing lines on one side along the length direction. A first moisturizing film layer 19 is glued and fixed to the upper surface of the outward-turned surface 21. The area of ​​the first moisturizing film layer 19 is larger than the area of ​​the outward-turned surface 21. A first non-removable adhesive layer 23 with an area equal to that of the outward-turned surface 21 is provided on the side of the outward-turned surface 21 facing the first moisturizing film layer 19. A first removable adhesive layer 24 with an edge corresponding to the side edge of the first moisturizing film layer 19 is provided around the outer side of the outward-turned surface 21.

[0022] The first moisturizing film layer 19 comprises, from the outside to the inside, a PET composite film anti-scratch layer, an aluminum foil composite film barrier layer, and a thermoplastic polyurethane film layer, which are sequentially laminated and fixed. This structural arrangement ensures that the first moisturizing film layer 19 balances flexibility and strength, thus guaranteeing its service life.

[0023] The box body includes a first adhesive fold 10, a first fold 11, a second fold 12, a third fold 13, a fourth fold 14, a fifth fold 15, a sixth fold 16 formed on opposite sides of the width direction of the first fold 11, a second adhesive fold 18 formed on opposite sides of the width direction of the second fold 12, and a third adhesive fold 20 formed on opposite sides of the width direction of the third fold 13. A tear line is cut across one side of the first fold 11, the second fold 12, and the third fold 13, forming an outward-turned surface 21. A first moisturizing film layer 19 is adhered and fixed on the first fold 11, the second fold 12, and the third fold 13 on the outward-turned surface 21. A first removable adhesive layer 24 is provided on the first fold 11, the second fold 12, and the third fold 13 in areas other than the outward-turned surface 21 and in positions covered by the first moisturizing film layer 19.

[0024] When the box is in the forming state, the first fold 11, the second fold 12, the third fold 13, and the fourth fold 14 are folded at 90° in sequence and then glued and fixed to the fourth fold 14 by the first adhesive fold 10. The second adhesive fold 18 on both sides and the third adhesive fold 20 on both sides are glued and fixed to the fifth fold 15 and the sixth fold 16 on the corresponding side, respectively.

[0025] The portion of the outward-folded surface 21 located on the third fold surface 13 has a centrally formed, protruding first semi-circular nail position 25. The portion of the first moisturizing film layer 19 located on the third fold surface 13 and corresponding to the position of the first semi-circular nail position 25 has a protruding second semi-circular nail position 22; the second semi-circular nail position 22 is set as a non-adhesive area 26. The first adhesive fold surface 10, the second adhesive fold surface 18, and the third adhesive fold surface 20 are all provided with a second non-removable adhesive layer.

[0026] When it is necessary to disassemble, the person pinches the second semicircular nail position 22 and lifts the first moisturizing film layer 19. During the process of lifting the first moisturizing film layer 19, the tear line of the outer flip-out side 21 is simultaneously broken. After the removal action is completed, the first moisturizing film layer 19 is bonded to the first removable adhesive layer 24 to achieve reclosure. The outer flip-out side 21 is also returned to the closed state, which facilitates secondary use.

[0027] In this embodiment, the upper part of the box has an outward-facing panel formed by a tear line along its length. To open it, the outward-facing panel must be torn along the tear line. This destructive opening method gives the structure anti-counterfeiting and anti-tampering functions. A first moisturizing film layer is adhered and fixed to the upper surface of the outward-facing panel. On one hand, after the outward-facing panel is opened, the first moisturizing film layer keeps the opening sealed. On the other hand, the first moisturizing film layer provides moisture retention to the opening of the outward-facing panel, thereby maintaining the quality of the product inside the packaging box. Furthermore, the box body is a one-piece molded structure, meeting the requirements of packaging machine processing, thus ensuring good production efficiency. This product can be used for cigarette packaging.

[0028] Reference Figure 5-6 In the second embodiment shown, based on the first embodiment, the sixth fold 16 is provided with a removable surface 17 formed by a rectangular tear line. After the removable surface 17 is detached from the box body, it forms a push-out window. A second moisturizing film layer 27 is attached to the sixth fold 16 at the position corresponding to the push-out window through a second removable adhesive layer. In actual operation, after removing the removable surface 17 along the rectangular tear line to form the push-out window, and after peeling off the second moisturizing film layer 27, a finger can be inserted into the push-out window to push the individual packaging box located inside the box body towards the outward flip 21, thus making it convenient for the user to take out the individual packaging box from the outward flip 21. After completing the push-out action, the second moisturizing film layer 27 is covered and the second removable adhesive layer is used to maintain the seal of the push-out window, thereby maintaining good moisturizing function.
