Description

Technical Field

[0001] This invention relates to the field of packaging box technology, specifically a gift box combination set. Background Technology

[0002] In the gift packaging industry, especially for perfumes, essential oils, high-value beverages, high-end cosmetics, and home fragrance diffusers, modular gift boxes are highly favored due to their excellent display capabilities, premium feel, and convenient gifting experience. These diffuser bottles typically contain multiple individual items, and the widely used packaging and securing method is "pre-formed die-cut lining." This involves precisely cutting holes or slots matching the shape of the diffuser bottle into a cardboard sheet of a certain thickness using a mold. The glass bottle is then directly placed into these holes during packaging, thus achieving the partitioning, positioning, and display of the diffuser bottle.

[0003] However, in the process of designing gift boxes, cost, functionality and aesthetics need to be taken into account. The inner lining cardboard used often has an upper limit in terms of stiffness and resilience. During the transportation or handling of the aromatherapy bottle, if the gift box is accidentally inverted or subjected to violent vibration, the glass bottle inside is very likely to fall out from the pre-formed holes, which will increase the breakage rate of the glass bottle.

A ninth crease is provided between the side support plate, diagonal support plate and straight support plate. A second shearing opening is provided between the diagonal support plates on both sides. The straight support plate is bonded and fixed to the inner wall of the packaging shell. The side support plate is located on the outer edge of the arc plate. Beneficial effects

[0013] This invention provides a gift box combination set. It has the following beneficial effects: In this invention, during the opening process of the door, the flipping strip attached between the door and the outer side of the placement platform can be used to pull the placement platform so that it rotates along the second crease to face the front, making it convenient to access the aromatherapy bottle in the placement hole.

[0014] In the process of opening and closing the door in this invention, the flipping strip bonded between the extension and the inner side of the placement platform can be used to pull the placement platform to rotate 90° along the second crease to face the support frame. The side support plate of the support frame abuts against the outside of the aromatherapy bottle in the placement hole, so that the aromatherapy bottle will not fall off during the transportation or handling of the aromatherapy bottle.

[0015] In this invention, by opening a horizontal shearing slit two on the diagonal brace and the side brace, the middle part of the support frame can be bent and protruded inward to limit the outer side of the aromatherapy bottle. The upper and lower sides protrude towards the side wall of the packaging shell and are bonded to the inner wall of the packaging shell. On the one hand, the inner and outer protruding structures can form a rhomboid structure, which improves the rigidity of the support frame. On the other hand, the upper and lower parts of the shearing slit two corresponding to the flipping belt can provide displacement space for the flipping belt to pull the placement platform, preventing the support frame from getting stuck on the flipping belt.

[0016] In this invention, the flip plate is limited by the folding plate and the fixing plate, and the rotation angle of the opening and closing door is restricted so that the opening and closing door can just rotate the placement table to the specified angle. In the open state, the opening and closing display effect is improved. In the closed state, the aromatherapy bottle can be directly aligned with the side support plate of the support frame, avoiding misalignment that could cause the aromatherapy bottle to loosen.

[0017] This invention, through the design of the blade structure, allows the gift box set to fold into a box shape that simulates an aromatherapy bottle. The opening and closing door drives the placement platform to flip, increasing the sense of ritual when opening the box and enhancing the aesthetics and fun of the packaging.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] This invention provides a gift box combination set, such as... Figure 1-9 As shown, it includes a packaging shell, drawers, a flip-up base, and a placement table.

[0022] like Figures 1-3As shown, the packaging shell includes a rear panel 1, a left side panel 2, a right side panel 3, and a lower side panel 4. A fourth crease is provided between the rear panel 1 and the left side panel 2, right side panel 3, and lower side panel 4. The rear panel 1 includes an integrally formed lower cavity and an upper cavity. The left and right sides of the lower cavity are provided with shaped beveled edges. The left side panel 2 and right side panel 3 are provided with shaped beveled edges that fit the shaped bevels. A front panel 5 is provided on the outer side of the left side panel 2 and right side panel 3. A fifth crease is provided between the front panel 5 and the left side panel 2 and right side panel 3. The edges of the rear panel 1 and the left side panel 2, right side panel 3, and lower side panel 4 are provided with adhesive edges for bonding. The front panel 5, rear panel 1, and left side panel 4 are connected to the left side panel 4. Panel 2, right side panel 3, and lower side panel 4 can be folded along the fourth and fifth folds to form a lower cavity shell for holding the aromatherapy bottle. A display opening for storing and displaying the aromatherapy bottle is provided between the two front side panels 5. An opening and closing panel 6 is integrally formed on the outer side of the front side panel 5. A first fold 101 is provided between the opening and closing panel 6 and the front side panel 5. An opening and closing door 7 is glued and fixed on the opening and closing panel 6, so that the opening and closing door 7 can rotate along the first fold 101 to open and close the display opening. A bending piece is provided at the end of the opening and closing door 7. An opening and closing fold crease is provided between the opening and closing door 7 and the bending piece. An integrally formed extension is provided on the inner side of the packaging shell for the opening and closing door 7.

[0023] like Figure 3 As shown, the lower side plate 4 is sequentially connected to a front sealing plate 8, a lower sealing plate 9, a rear sealing plate 10, an upper sealing plate 11, and an opening / closing sealing plate 12. An eighth crease is provided between the front sealing plate 8, the lower sealing plate 9, the rear sealing plate 10, the upper sealing plate 11, and the opening / closing sealing plate 12. The upper sealing plate 11, the opening / closing sealing plate 12, and the lower connecting plate 15 are bent together to form an opening / closing slot. When the opening / closing door 7 is closed, the bent piece can be inserted into the opening / closing slot to keep the opening / closing door 7 in a closed state.

[0024] like Figure 3 As shown, the upper side of the upper cavity is integrally formed with an upper connecting plate 13, a front connecting plate 14, a side connecting plate 14, and a lower connecting plate 15. A sixth crease is provided between the upper connecting plate 13 and the front connecting plate 14, the side connecting plate 14 and the lower connecting plate 15. The lower connecting plate 15 is bonded and fixed to the upper side of the left side plate 2 and the right side plate 3. The rear side plate 1, the front connecting plate 14, the side connecting plate 14 and the lower connecting plate 15 are folded into a pull-out opening. The two lower connecting plates 15 are bonded together in a cross pattern and are set between the upper cavity and the lower cavity, serving as the top plate of the display opening and the bottom plate of the pull-out opening.

[0025] like Figure 3As shown, the drawer includes a drawer bottom panel 16 and four drawer side panels 18. A seventh crease is provided between the drawer side panels 18 and the drawer bottom panel 16. The four drawer side panels 18 are glued together and together with the drawer bottom panel 16 form a drawer with an upper opening. The drawer is slidably installed in the pull-out opening.

[0026] like Figures 6-7 As shown, the placement platform includes an adhesive plate 22, an arc plate 23, and two upper and lower semi-circular plates 24. The adhesive plate 22 is fixed to the flip plate 21. A third crease is provided between the adhesive plate 22 and the semi-circular plates 24. A butt crease is provided between the arc plate 23 and the adhesive plate 22. A placement hole 17 is provided in the middle of the arc plate 23. The adhesive plate 22, the arc plate 23, and the upper and lower semi-circular plates 24 can be bonded together along the third crease and the butt crease to form a semi-cylindrical structure. The upper and lower sides of the middle of the arc plate 23 are provided with... A horizontally extending shearing notch 104 is provided. Two concave creases 103 are symmetrically arranged on both sides of the placement hole. Folding along the concave creases 103 can form a concave structure for placing the aromatherapy bottle. The adhesive plate 22 provides rear support for the aromatherapy bottle on the inner side, and the inner edge of the placement hole provides lateral support for the aromatherapy bottle, keeping the outer edge of the aromatherapy bottle located on the inner side of the outer edge of the arc plate 23. A support plate is provided on the front side of the adhesive plate 22. The support plate is in a concave-convex fit against the rear side of the arc plate 23, which can improve the structural strength of the placement platform.

[0027] like Figures 1-2 As shown, the line connecting the first crease 101 and the second crease 102 forms a 45° angle with the horizontal plane. A flip-up strip 25 is bonded to the extension 26 and the opening / closing door 7, respectively. The flip-up strip 25 is made of elastic material. The bonding positions of the flip-up strips 25 on the extension and the opening / closing door 7 are equidistant from the first crease 101. The flip-up strip 25 connected to the extension 26 is bonded to the inner side of the placement platform, and the flip-up strip 25 connected to the opening / closing door 7 is bonded to the outer side of the placement platform. The two flip-up strips 25 are staggered and arranged on the upper and lower sides of the placement platform, respectively. When the opening / closing door 7 is rotated, the lengths of the two flip-up strips 25 can be adjusted. The degree of change remains constant. During the opening and closing of the door 7, the flipping strap 25 connected to the outside of the placement platform on the door 7 gradually tightens and pulls the placement platform outward around the second crease 102 until the door is fully open, so that the placement platform faces outward for easy access and display of the aromatherapy bottle. When the door 7 is closed, the flipping strap 25 connected to the inside of the placement platform on the extension 26 gradually tightens and pulls the placement platform inward around the second crease 102 until the door 7 is fully closed, so that the placement platform rotates 90° toward the side wall of the packaging shell and, by abutting against the outside of the arc plate 23, prevents the aromatherapy bottle in the placement hole from falling out.

[0028] like Figures 4-5As shown, the flip-up seat includes a connecting seat 1 and a connecting seat 2 that are interlocked together. Both connecting seat 1 and connecting seat 2 include symmetrically arranged folding plates 19 and fixing plates 20. A shearing notch 107 is provided in the middle of the folding plate 19, and the bent shearing notch 107 together form a positioning groove. The folding plate 19 of connecting seat 2 is perpendicular to the folding plate 19 of connecting seat 1. The positioning grooves of connecting seat 1 and connecting seat 2 are interlocked and fixed. The fixing plate 20 of connecting seat 2 is bonded and fixed to the packaging shell. The folding plate 19 of connecting seat 2 abuts against the rear side of the fixing plate 20 of connecting seat 1, which keeps the fixing plate 20 of connecting seat 1 fixed. A flip-up plate 21 is integrally formed on the outer side of the fixing plate 20 of connecting seat 1. The flip-up plate 21 and the fixing plate 20... A second crease 102 is provided between the 0 and 0. The placement platform is glued and fixed to the flip plate 21. The width of the placement platform is equal to the sum of the width of the flip plate 21 and the fixed plate 20. The flip plate 21 is glued to the outer part of the placement platform, which allows the placement platform to rotate around the second crease 102. When rotating outward, the fixed plate 20 of the connecting seat 1 can limit the placement platform, so that it can only rotate forward to face the outside. When rotating inward, the folding plate 19 of the connecting seat 2 can limit the placement platform, so that it can only rotate backward to 90° towards the side wall of the mounting shell. Furthermore, the rotation angle of the opening and closing door can be limited by the flipping belt 25, so that it can only open 90°. This can solve the problem in the above technical solution where the rotation angle of the opening and closing door is too large, causing the rotation angle of the placement platform to be too large, which affects the display effect of the aromatherapy bottle.

[0029] like Figures 8-9As shown, a support frame is bonded to the inner wall of the packaging shell. The support frame is located near the outer edge of the arc plate. The support frame includes a side support plate 27 and diagonal support plates 28 and straight support plates 29 symmetrically arranged on both sides of the side support plate 27. A ninth fold is provided between the side support plate 27, diagonal support plates 28, and straight support plates 29. The straight support plate 29 is bonded and fixed to the inner wall of the packaging shell. A second shearing opening 105 is provided between the diagonal support plates 28 on both sides. The second shearing opening 105 penetrates the diagonal support plate 28 and the side support plate 27. The distance between the second shearing opening 105 and the upper and lower edges of the diagonal support plate 28 is greater than the width of the mounting strip. The portion between the two second shearing openings 105 bends and protrudes towards the center along the ninth fold, making... The side support plate 27 protrudes to the outer edge of the arc plate 23 and is located at the front of the center of the placement platform after rotating 90°. It forms an outer limit on the aromatherapy bottle in the placement hole, preventing the aromatherapy bottle from falling off during transportation or handling. At the same time, the outer part of the second shear 105 bends and protrudes towards the side wall of the packaging shell. This part of the side support plate 27 is bonded to the side wall of the packaging shell, forming a diamond structure, which improves the structural strength of the support frame. In addition, the second shear 105 can make the lower part protrude inward, and the front part provides stretching space for the flipping belt 25, avoiding the support frame from blocking the flipping belt 25 and ensuring that the flipping belt 25 is stretched smoothly. This can solve the problem of the support frame jamming the flipping belt 25 in the above technical solution.

[0030] Working principle: In this invention, since the line connecting the first crease 101 and the second crease 102 forms a 45° angle with the horizontal plane, the bonding position of the flip-over strip 25 is equidistant from the first crease 101, so that during the rotation of the opening and closing door 7, the displacement difference between the bonding position and the placement table during the rotation process is always equal, that is, the placement table can be smoothly rotated by rotating the opening and closing door 7.

[0031] When the opening and closing door 7 is opened, the flipping belt 25 connected to the opening and closing door 7 is gradually tightened and drives the placement table to rotate outward around the second crease 102 to a horizontal position. During this process, the rotating placement table will simultaneously pull the flipping belt 25 connected to the extension 26 so that it partially wraps around the front side of the arc plate 23, which makes it convenient to pick up, put down and display the aromatherapy bottle on the placement table. When the opening and closing door 7 is closed, the extension 26 gradually rotates away from the second crease 102. The flipping belt 25 connected to the extension 26 gradually tightens and pulls the placement platform to rotate in the opposite direction around the second crease 102 until the opening and closing door 7 is completely closed. The placement platform flips 90°. At this time, the placement hole of the placement platform is directly opposite the side support plate 27 of the support frame. The side support plate 27 forms a support limit on the outside of the aromatherapy bottle in the placement hole, so that the aromatherapy bottle will not fall off during the transportation or handling of the aromatherapy bottle.
