Description

Technical Field

[0001] The invention belongs to the technical field of packaging, and in particular relates to a novel packaging box which can display different pictures by opening and closing, and a preparation method and use thereof. Background Art

[0002] Focusing on the cigarette product R&D needs of "enhancing consumers' sensory experience, increasing cigarette brand recognition and creating new product selling points", cigarette packaging has constructed a multimodal interactive cigarette packaging structure design technology by studying the multimodal interaction methods of consumers at three different demand levels: basic layer, composite layer and intelligent layer. Therefore, in order to increase product competitiveness, cigarette packaging box innovation should focus on multimodal interactive cigarette packaging structure design technology, and should provide consumers with a product experience that integrates interactive functions such as vision, touch, hearing, and emotional connection.

[0003] Patent CN2020101130671 discloses a technical solution in which the front pattern of the outer box body appears at different levels and alternates with each other. However, the patent is not fully disclosed, and its functions and effects cannot be achieved according to the technical solution disclosed therein, such as how the presentation part A and the presentation part B are staggered and distributed, and how the presentation part B moves with the inner box body. Second, the presentation component of the patent requires an envelope, and slats are also provided on both sides of the inner box body, that is, the inner box body needs to have two-layer walls on both sides; this increases the amount of production materials and correspondingly increases its production cost. Third, the setting of the upper limit groove of the slats of the patent increases the volume of the inner and outer boxes, which increases the difficulty of calculating the internal control dimensions of the small cigarette packaging box (generally 10 packs); at the same time, it increases the amount of production materials and correspondingly increases its production cost.

[0024] The packaging box for containing ten small cigarette boxes of the present invention, the method of displaying different pictures on the unfolding surface A or the closing surface B on the display window 10:

[0025] The inner box body 2 of the packaging box is inside the outer box body 1, and ten boxes of cigarettes (ordinary cigarette boxes) are inside the inner box body 2, and the packaging box is in a packaged state; at this time, since the closed surface B covers the unfolded surface A, the entire image of the closed surface B is displayed on the display window 10. Pull the pull rope 22 in the horseshoe-shaped hollow 21, the inner box body 2 moves to the right, and the outer box body 1 is stationary; after the inner box body 2 moves to the right for a distance, the left inner wall of the inner box body 2 clamps the clamping strip 42 on the sliding plate 4, and the inner box body 2 drives the sliding plate 4 to move to the right. At this time, the first, second, third and fourth sub-closing surface bodies (b1, b2, b3 and b4) are slowly inserted under the second, third, fourth and fifth sub-expanding surface bodies (a2, a3, a4 and a5), and as the inner box body 2 continues to move to the right, until the clamping strip 42 is clamped by the right side wall of the hollow area 32, the first, second, third and fourth sub-closing surface bodies (b1, b2, b3 and b4) are completely inserted under the second, third, fourth and fifth sub-expanding surface bodies (a2, a3, a4 and a5), and the overall picture of the expansion surface A is displayed on the display window 10; at this time, one or more boxes of cigarettes can be taken out;

The body 2 continues to move to the left until the card 41 abuts against the left inner wall of the outer box body 1. At this time, the first, second, third and fourth sub-closing surface bodies (b1, b2, b3 and b4) are completely moved out from under the second, third, fourth and fifth sub-expanding surface bodies (a2, a3, a4 and a5), and the first, second, third, fourth and fifth sub-expanding surface bodies (a1, a2, a3, a4 and a5) are completely covered by the first, second, third, fourth and fifth sub-closing surface bodies (b1, b2, b3, b4 and b5). The inner box body 2 completely enters the outer box body 1, and the entire packaging box is in a packaging state. At this time, the overall picture of the closing surface B is displayed on the display window 10.

[0027] Therefore, the packaging box of the present invention can drive the closing surface B to move left and right by opening and closing the inner box body 2, and display the image of the expanded surface A or the image of the closed surface B in the display window 10, that is, two different images can be presented in the display window 10.

[0028] Beneficial effects of the present invention:

[0029] The packaging box of the present invention can present different pictures on the packaging box surface (display window) by opening and closing the inner box body. The packaging box of the present invention can also present different dynamic pictures on the packaging box surface (display window) through clever design, giving consumers an interesting spatial dynamic experience and visual impact. The packaging box of the present invention is used for containing ten boxes of ordinary cigarettes in the inner box body, and is well received by consumers. BRIEF DESCRIPTION OF THE DRAWINGS
