Description

A packaging box that displays different images by opening and closing, its preparation method and uses. Technical Field

[0001] This invention belongs to the field of packaging technology, specifically relating to a novel packaging box that displays different images by opening and closing, its preparation method, and its uses. Background Technology

[0002] To meet the R&D needs of cigarette products—namely, to enhance consumer sensory experience, improve brand recognition, and create new selling points—cigarette packaging research has developed a multimodal interactive cigarette packaging structure design technology by studying multimodal interaction methods among consumers at three different levels of needs: basic layer, composite layer, and intelligent layer. Therefore, to increase product competitiveness, innovation in cigarette packaging should focus on multimodal interactive cigarette packaging structure design technology, providing consumers with a product experience that integrates visual, tactile, auditory, and emotional connections.

[0003] Patent CN2020101130671 discloses a technical solution where the front pattern of the outer box features different layers that alternate with each other. However, this patent is insufficiently disclosed, and its functions and effects cannot be achieved according to the disclosed technical solution. For example, it is unclear how presentation parts A and B are staggered, and how presentation part B moves with the inner box. Second, the presentation component of this patent requires a sleeve, and its inner box also has strips on both sides, meaning that its inner box requires two layers of side walls; this increases the amount of production materials used, and correspondingly increases its production cost. Third, the upper limit groove of the strips in this patent increases the volume of its inner and outer boxes, which increases the difficulty of calculating the internal control dimensions of cigarette packaging boxes (generally 10 packs); it also increases the amount of production materials used, and correspondingly increases its production cost. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a packaging box that displays different images when opened and closed, for use in cigarette packaging cartons. The packaging box of this invention presents two dynamic images when the inner box is opened and closed, offering a novel spatial dynamic experience and a strong visual impact.

[0014] The second aspect of this invention discloses a method for preparing a packaging box that displays different images by opening and closing, comprising the following steps:

[0015] S1: Cut a rectangular groove 31 from the middle of the left end of the rectangular piece, and cut a square cutout area 32 from the inner edge of the right end. The length of the square of the cutout area 32 is not less than the depth of the groove 31, to obtain the unfolded frame 3; cut the unfolded surface A into five sub-unfolded surfaces A1, A2, A3, A4 and A5 of equal area. Cut two slits of equal length from the left side on the upper and lower edges of the five sub-unfolded surfaces respectively, leaving the right side connected without cutting to form the sub-unfolded surface connecting strip M3; sequentially glue the upper edge M1 of the five sub-unfolded surfaces to the upper edge of the unfolded frame 3, and sequentially glue the lower edge M2 of the five sub-unfolded surfaces to the lower edge of the unfolded frame 3. There is a gap between the unfolded frame 3 and the unfolded surface.

[0016] S2: Place the card 41 vertically downwards at the left end of the rectangular piece. The width of the card 41 is slightly smaller than the width of the groove 31. Thicken the lower edge of the right end to form a card strip 42, thus obtaining a sliding piece 4 whose length and width are both smaller than the unfolded frame 3. Insert the sliding piece 4 into the unfolded frame 3 and the unfolded surface.

[0017] In the gap between them, the card strip 42 is on the left edge of the hollow area 32, and the card 41 is on the left edge of the groove 31;

[0018] S3: Cut the sealing surface B into five separate sealing surfaces B1, B2, B3, B4 and B5 with equal areas; cut two slits of equal length from the right side on the upper and lower edges of the five separate sealing surfaces respectively, leaving the left side connected without cutting to form the sealing surface connecting strip N3, where the first separate sealing surface B1 leaves a protruding part b11 on the right side; glue the upper edges N1 of the five separate sealing surfaces together in sequence, and glue the lower edges N2 of the five separate sealing surfaces together in sequence to obtain the overall sealing surface B;

[0019] S4: Adhere the protruding part b11 in the middle of the first sub-closed surface body b1 of the overall closing surface B obtained in step S3 to the sliding plate 4, so that the right edge of the first sub-closed surface body b1 is inserted under the left edge of the second sub-expanded surface body a2, and ensure that the first sub-closed surface body b1 completely covers the first sub-expanded surface body a1; the right edge of the second sub-closed surface body b2 is inserted under the left edge of the third sub-expanded surface body a3, and ensure that the second sub-closed surface body b2 completely covers the second sub-expanded surface body a2; the right edge of the third sub-closed surface body b3 is inserted under the left edge of the fourth sub-expanded surface body a4, and ensure that the third sub-closed surface body b3 completely covers the third sub-expanded surface body a3; the right edge of the fourth sub-closed surface body b4 is inserted under the left edge of the fifth sub-expanded surface body a4, and ensure that the fourth sub-closed surface body b4 completely covers the fourth sub-expanded surface body a4; the fifth sub-closed surface body b5 completely covers the fifth sub-expanded surface body a5.

[0020] S5: Attach the upper and lower edges of the unfolded frame 3 obtained in step S4 to the inner wall of the upper end face of the outer box 1; unfolded surface A is on the display window 10;

[0021] S6: Bond the five walls of the outer box 1 together to obtain an outer box 1 without a right side wall. The matching inner box 2 is inside the outer box 1, so that the card 41 is outside the left side wall of the inner box 2 and inside the left side wall of the outer box 1, and the card strip 42 is inside the inner box 2; that is, the packaging box is obtained.

[0022] The third aspect of this invention discloses the use of the packaging box that displays different images by opening and closing for use in cigarette packaging cartons.

[0023] Preferably, ten boxes of cigarettes are placed inside the inner box 2 of the cigarette packaging carton.

[0024] The present invention discloses a method for displaying different images on the unfolded surface A or the closed surface B on the display window 10 of a packaging box for holding ten small packs of cigarettes:

[0025] The inner box 2 of the packaging box is inside the outer box 1, and ten boxes of cigarettes (ordinary cigarette boxes) are inside the inner box 2. The packaging box is in a packaged state. At this time, since the closed surface B covers the unfolded surface A, the display window 10 shows the overall picture of the closed surface B. Pull the rope 22 in the horseshoe-shaped cutout 21, and the inner box 2 moves to the right while the outer box 1 remains stationary. After the inner box 2 moves a certain distance to the right, the left inner wall of the inner box 2 engages with the locking strip 42 on the sliding piece 4. The inner box 2 then moves the sliding piece 4 to the right. At this time, the first, second, third, and fourth closed surfaces (b1, b2, b3, and b4) slowly insert under the second, third, fourth, and fifth unfolded surfaces (a2, a3, a4, and a5). As the inner box 2 continues to move to the right, the locking strip 42 is engaged by the right side wall of the cutout area 32. At this time, the first, second, third, and fourth closed surfaces (b1, b2, b3, and b4) are completely inserted under the second, third, fourth, and fifth unfolded surfaces (a2, a3, a4, and a5), and the overall picture of the unfolded surface A is displayed on the display window 10. At this time, one or more boxes of cigarettes can be taken out.

[0026] Push the inner box 2 to the left, while the outer box 1 remains stationary. After the inner box 2 moves a certain distance to the left, the left outer wall of the inner box 2 engages with the card 41 on the sliding piece 4. The inner box 2 then moves the sliding piece 4 to the left. At this time, the first, second, third, and fourth closed surfaces (b1, b2, b3, and b4) slowly move out from under the second, third, fourth, and fifth unfolded surfaces (a2, a3, a4, and a5), and are gradually covered by the first, second, third, fourth, and fifth closed surfaces (b1, b2, b3, b4, and b5). Body 2 continues to move to the left until card 41 touches the inner left side wall of outer box 1. At this time, the first, second, third and fourth closed surfaces (b1, b2, b3 and b4) completely move out from under the second, third, fourth and fifth unfolded surfaces (a2, a3, a4 and a5). The first, second, third, fourth and fifth unfolded surfaces (a1, a2, a3, a4 and a5) are completely covered by the first, second, third, fourth and fifth closed surfaces (b1, b2, b3, b4 and b5). Inner box 2 is completely inside outer box 1, and the entire packaging box is in a packaged state. At this time, the overall picture of closed surface B is displayed on display window 10.

[0027] Therefore, the packaging box of the present invention can move the closing surface B left and right by opening and closing the inner box body 2, and display the image of the unfolded 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] The beneficial effects of this invention are:

[0029] The packaging box of this invention displays different images on its surface (display window) by opening and closing the inner box. Through clever design, the packaging box can also display different dynamic images on its surface (display window), providing consumers with an engaging and dynamic spatial experience and visual impact. The packaging box of this invention is used to hold ten cartons of ordinary cigarettes within its inner box and has been well-received by consumers. Attached Figure Description

[0050] As shown in Figures 1-13, a packaging box of the present invention that displays different images by opening and closing includes an outer box body 1 and an inner box body 2; a display window 10 is provided on the upper surface of the outer box body 1; the different images are displayed on the unfolded surface A or the closed surface B on the display window 10; the unfolded surface A is fixed on the display window 10; by opening and closing the inner box body 2, the closed surface B is moved left and right, and the image of the unfolded surface A or the image of the closed surface B is displayed on the display window 10.

[0051] The upper and lower edges of the unfolded surface A are respectively bonded to the unfolded surface frame 3. The upper and lower edges of the unfolded surface frame 3 are bonded to the inner wall of the upper end face of the outer box 1, and there is a gap between the unfolded surface frame 3 and the inner wall of the upper end face of the outer box 1. The upper and lower edges of the closing surface B are bonded to the upper surface of the sliding piece 4. The sliding piece 4 is arranged in the gap between the unfolded surface frame 3 and the inner wall of the upper end face of the outer box 1. The sliding piece 4 slides left and right in the gap by opening and closing the inner box 2.

[0052] As shown in Figure 3, the unfolded frame 3 is rectangular, with a rectangular groove 31 in the middle of its left end and a square cutout area 32 inside its right edge. The length of the square cutout area 32 is not less than the depth of the groove 31. As shown in Figure 4, the sliding piece 4 is rectangular, with its length and width being smaller than the length and width of the unfolded frame 3. The left end of the sliding piece 4 has a vertically downward-pointing piece called a card 41, and the lower right edge of the sliding piece 4 is thickened to form a card strip 42. The card 41 passes through the groove 31 and is fixedly vertically connected to the sliding piece 4. The card strip 42 is arranged within the cutout area 32, and the length of the card strip 42 can be greater than the length of the square cutout area 32.

[0053] The unfolded surface A is divided into several sub-unfolded surfaces A1, A2, A3, ... with equal areas; the closed surface B is also divided into closed surfaces B1, B2, B3, ... with the same number as the sub-unfolded surfaces A1, A2, A3, ...; the width of each closed surface B1, B2, B3, ... is slightly larger than the width of each sub-unfolded surface A1, A2, A3, ... and each closed surface B1, B2, B3, ... covers each sub-unfolded surface A1, A2, A3, ... respectively.

[0054] In this embodiment, as shown in Figure 7, there are five unfolded surfaces A1, A2, A3, ..., which are respectively the first unfolded surface A1, the second unfolded surface A2, the third unfolded surface A3, the fourth unfolded surface A4, and the fifth unfolded surface A5 (the reference numerals A2, A3, A4, and A5 are not shown). The shape of each unfolded surface is as follows: there are two slits of equal length starting from the left side on the upper edge M1 and the lower edge M2 of the unfolded surface. The right side of the unfolded surface is connected to form the unfolded surface connecting strip M3. The middle part is the main body of the unfolded surface. The five main bodies of the unfolded surface are respectively the first unfolded surface main body a1, the second unfolded surface main body a2, the third unfolded surface main body a3, the fourth unfolded surface main body a4, and the fifth unfolded surface main body a5 (the reference numerals a2, a3, a4, and a5 are not shown).

[0055] In this embodiment, as shown in Figure 8, there are five separating surfaces B1, B2, B3, ..., namely, the first separating surface B1, the second separating surface B2, the third separating surface B3, the fourth separating surface B4, and the fifth separating surface B5 (the reference numerals B2, B3, B4, and B5 are not shown). The shape of each separating surface is as follows: there are two gaps of equal length starting from the right side on the upper edge N1 and the lower edge N2 of the separating surface; the left side of the separating surface is connected to form the separating surface connecting strip N3; the middle part is the main body of the separating surface; the five main bodies of the separating surfaces are the first separating surface main body b1, the second separating surface main body b2, the third separating surface main body b3, the fourth separating surface main body b4, and the fifth separating surface main body b5 (the reference numerals b2, b3, b4, and b5 are not shown). The first separating surface main body b1 has a protruding part b11 in the middle of the right side.

[0056] The right edge of the first split-closed surface main body b1 is inserted below the left edge of the second split-unfolded surface main body a2, and the protruding part b11 in the middle is bonded and fixed to the sliding plate 4, and the first split-closed surface main body b1 completely covers the first split-unfolded surface main body a1. The right edge of the second split-closed surface main body b2 is inserted below the left edge of the third split-unfolded surface main body a3, and the second split-closed surface main body b2 completely covers the second split-unfolded surface main body a2. The right edge of the third split-closed surface main body b3 is inserted below the left edge of the fourth split-unfolded surface main body a4, and the third split-closed surface main body b3 completely covers the third split-unfolded surface main body a3.

[0057] The outer box 1 has no right side wall, as shown in Figure 12, which is a schematic diagram of the unfolded outer box of the packaging box of the present invention; the size of the inner box 2 is adapted to the outer box 1; the inner box 2 has no upper side wall, and there is a horseshoe-shaped cutout 21 in the middle of the right outer side wall of the inner box 2, and a pull rope 22 is provided in the horseshoe-shaped cutout 21; as shown in Figure 2.

[0058] The present invention provides a method for preparing a packaging box that displays different images by opening and closing, comprising the following steps:

[0059] S1: Cut a rectangular groove 31 from the middle of the left end of the rectangular piece, and cut a square cutout area 32 from the inner edge of the right end. The length of the square cutout area 32 is not less than the depth of the groove 31, thus obtaining the unfolded frame 3, as shown in Figure 3. Cut the unfolded surface A into five sub-unfolded surfaces A1, A2, A3, A4 and A5 of equal area. Cut two slits of equal length from the left side of the upper and lower edges of the five sub-unfolded surfaces, leaving the right side connected without cutting, as the sub-unfolded surface connecting strip M3. Glue the upper edges M1 of the five sub-unfolded surfaces together in sequence as shown in Figure 7. Then glue the glued upper edges M1 to the upper edge of the unfolded frame 3. Glue the lower edges M2 of the five sub-unfolded surfaces together in sequence. Then glue the glued lower edges M2 to the lower edge of the unfolded frame 3. There is a gap between the unfolded frame 3 and the unfolded surface; as shown in Figures 7 and 11.

[0060] S2: Place the card 41 vertically downwards at the left end of the rectangular piece. The width of the card 41 is slightly smaller than the width of the groove 31. The lower edge of the right end is thickened into a strip 42. The strip 42 is larger than the length of the square of the hollow area 32, thus obtaining a sliding piece 4 whose length and width are both smaller than the unfolded frame 3, as shown in Figure 4. Insert the sliding piece 4 into the gap between the unfolded frame 3 and the unfolded surface, with the strip 42 at the left edge of the hollow area 32 and at the bottom of the square of the hollow area 32. In this way, the sliding piece 4 and the unfolded frame 3 are locked together, and the card 41 is at the left edge of the groove 31. In the figures 5 and 6, where the unfolded frame and the sliding piece are combined, the sliding piece 4 has slid a distance to the right.

[0061] S3: Cut the sealing surface B into five separate sealing surfaces B1, B2, B3, B4 and B5 with equal areas; cut two slits of equal length from the right side of the upper and lower edges of the five separate sealing surfaces, leaving the left side connected without cutting to form the sealing surface connecting strip N3, where the first separate sealing surface B1 leaves a protruding part b11 on the right side, as shown in Figure 8; glue the upper edges N1 of the five separate sealing surfaces together in sequence, and glue the lower edges N2 of the five separate sealing surfaces together in sequence to obtain the overall sealing surface B, as shown in Figure 9.

[0062] S4: Adhere the protruding portion b11 in the middle of the first sub-grouting surface body b1 of the overall grouting surface B obtained in step S3 to the sliding sheet 4 surface, while ensuring that the right edge of the first sub-grouting surface body b1 is inserted below the left edge of the second sub-expanding surface body a2, and that the first sub-grouting surface body b1 completely covers the first sub-expanding surface body a1; the right edge of the second sub-grouting surface body b2 is inserted below the left edge of the third sub-expanding surface body a3, and that the second sub-grouting surface body b2 completely covers the second sub-expanding surface body a2; the right edge of the third sub-grouting surface body b3 is inserted below the left edge of the fourth sub-expanding surface body a4, and that the third sub-grouting surface body b3 completely covers the third sub-expanding surface body a4. The main body a3 of the open surface, the right edge of the fourth closing surface main body b4 is inserted below the left edge of the fifth unfolding surface main body a4, and the fourth closing surface main body b4 completely covers the fourth unfolding surface main body a4. The fifth closing surface main body b5 completely covers the fifth unfolding surface main body a5, as shown in Figure 11. Figure 11 is a schematic diagram of the unfolding surface frame and the sliding piece after the overall unfolding surface of Figure 10 is bonded to the unfolding surface frame and the overall closing surface is bonded to the sliding piece. The five closing surface main bodies partially cover the five unfolding surface main bodies respectively. Figure 10 is a schematic diagram of the relative positions of the overall unfolding surface and the overall closing surface in the combination of the unfolding surface frame and the sliding piece.

[0063] S5: Attach the upper and lower edges (shaded parts of the upper and lower edges in Figure 11) of the unfolded frame 3 obtained in step S4 to the inner wall of the upper end face of the outer box 1; the overall unfolded surface A is on the display window 10.

[0064] S6: Bond the five walls of the outer box 1 shown in Figure 12 together to obtain an outer box 1 without a right side wall. The matching inner box 2 is inside the outer box 1, so that the card 41 is outside the left side wall of the inner box 2 and inside the left side wall of the outer box 1, and the card strip 42 is inside the inner box 2; that is, the packaging box is obtained, as shown in the overall schematic diagram of the packaging box of the present invention in Figure 1, and the schematic diagram of the inner box of the packaging box of the present invention in the fully opened state in Figure 13.

[0065] The present invention relates to a packaging box that displays different images by opening and closing, which is used for cigarette packaging cartons. The inner box 2 of the cigarette packaging carton contains ten cartons of cigarettes.

[0066] The packaging box of this invention, used for cigarette carton packaging, has been industrially produced and is now available on the market. Figures 14-18 are photographs of the packaging box of this invention in different states.

[0067] The method of displaying different images on the unfolded surface A or the closed surface B on the display window 10 of the packaging box of the present invention:

[0068] As shown in Figure 14, the inner box 2 of the packaging box is inside the outer box 1, and the packaging box is in a packaged state; at this time, since the closed surface B covers the unfolded surface A, the display window 10 shows the overall picture of the closed surface B.

[0069] Pulling the rope 22 in the horseshoe-shaped hollow 21 moves the inner box 2 to the right, while the outer box 1 remains stationary. After the inner box 2 moves a certain distance to the right, the left inner wall of the inner box 2 engages with the locking strip 42 on the sliding piece 4. The inner box 2 then moves the sliding piece 4 to the right. At this time, the first, second, third, and fourth closed surface main bodies (b1, b2, b3, and b4) slowly insert under the second, third, fourth, and fifth unfolded surface main bodies (a2, a3, a4, and a5), as shown in Figure 1. In the photos of Figures 5 and 16, the closed surface B partially covers the unfolded surface A; as the inner box 2 continues to move to the right until the clip 42 is blocked by the right side wall of the cutout area 32, the first, second, third and fourth closed surface main bodies (b1, b2, b3 and b4) are completely inserted under the second, third, fourth and fifth unfolded surface main bodies (a2, a3, a4 and a5), and the overall picture of the unfolded surface A is displayed on the display window 10, as shown in the photos of Figures 17 and 18;

[0070] Push the inner box 2 to the left, while the outer box 1 remains stationary. After the inner box 2 moves a certain distance to the left, the left outer wall of the inner box 2 engages with the card 41 on the sliding piece 4. The inner box 2 then moves the sliding piece 4 to the left. At this time, the first, second, third, and fourth closed surfaces (b1, b2, b3, and b4) slowly move out from under the second, third, fourth, and fifth unfolded surfaces (a2, a3, a4, and a5). The first, second, third, fourth, and fifth unfolded surfaces (a1, a2, a3, a4, and a5) are gradually covered by the first, second, third, fourth, and fifth closed surfaces (b1, b2, b3, b4, and b5), as shown in photographs 15 and 16. Box 2 continues to move to the left until card 41 abuts against the inner left side of outer box 1. At this point, the first, second, third, and fourth closed surfaces (b1, b2, b3, and b4) completely move out from under the second, third, fourth, and fifth unfolded surfaces (a2, a3, a4, and a5). The first, second, third, fourth, and fifth unfolded surfaces (a1, a2, a3, a4, and a5) are completely covered by the first, second, third, fourth, and fifth closed surfaces (b1, b2, b3, b4, and b5). Inner box 2 is completely inside outer box 1, and the entire packaging box is in a packaged state. At this time, the overall image of closed surface B is displayed on display window 10, as shown in photo 14.

[0071] Therefore, the packaging box of the present invention can move the closing surface B left and right by opening and closing the inner box body 2, and display the image of the unfolded 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.

[0072] The overall unfolded surface A of this invention displays the "Double Ninth Festival" pattern, as shown in Figure 14; the overall closed surface B displays a cartoon pattern, as shown in Figures 17 and 18. The packaging box of this invention can display two different images in the display window by opening and closing the inner box. This invention can also integrate the images on the unfolded surface A and the closed surface B, presenting a dynamic image in the display window by moving the closed surface B left and right.

[0073] The above embodiments are not intended to limit the present invention, nor is the present invention limited to the examples described above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the present invention are also within the protection scope of the present invention.
