Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging products, in particular to a foldable heart-shaped packaging box. BACKGROUND

[0002] Heart-shaped gift boxes are favored in the jewelry, chocolate, cosmetics, and fine gift industries due to their unique emotional expression characteristics. Their unique shape can directly convey romantic, caring, and cherished emotions, thereby enhancing the experience of the gift recipient.

[0003] In traditional heart-shaped gift boxes, there are generally fixed integrated structures or simple upper and lower cover forms. The fixed integrated structure uses pulp molding, injection molding, or fixed pasting processes to permanently combine the box body and the box cover into a solid three-dimensional heart shape. This structure has a complete appearance and a high-quality feel, but it has no deformation ability at all. The upper and lower cover form uses a heart-shaped base and a heart-shaped cover. Although it can be opened and closed, its three-dimensional shape still occupies almost the same space as the fixed structure in the closed state.

[0004] However, the traditional heart-shaped gift box has a very low space utilization rate and high logistics and storage costs due to its fixed three-dimensional shape during transportation and storage. SUMMARY

[0005] To solve the above technical problems, the present application provides a foldable heart-shaped packaging box that can be folded, reducing the occupied space and reducing storage costs.

[0022] The technical solutions in the present application will be described clearly and completely in the following with reference to the drawings in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] In view of the problem that the traditional heart-shaped gift box adopts a fixed integrated structure or an upper and lower cover form, resulting in large occupied area and high transportation cost, the present application provides a foldable heart-shaped packaging box which can be folded to reduce the occupied space and reduce the storage cost. The specific implementation structure of the present application is described as follows: Referring to Figures 1 to 9 The present application first provides an embodiment of a foldable heart-shaped packaging box, which comprises: Box body 01 and box lid 02; Box body 01 includes a first side wall portion 03 and a second side wall portion 04, which are connected and enclose to form a heart-shaped receiving groove; the first side wall portion 03 has three parallel first vertical creases 05, and the second side wall portion 04 has three corresponding parallel second vertical creases 06; the positions of the first vertical creases 05 and the second vertical creases 06 are symmetrically distributed about the axis of symmetry of the heart-shaped receiving groove; Box lid 02 includes a first cover plate 07 connected to the first side wall portion 03 and a second cover plate 08 connected to the second side wall portion 04, the free ends of the first cover plate 07 and the second cover plate 08 overlapping each other; heart-shaped receiving groove A pull plate 09 is provided at the bottom of the groove, and the outline of the pull plate 09 matches the bottom outline of the heart-shaped receiving groove. A flexible traction piece 10 is provided on the lower surface of the pull plate 09, and the other end of the flexible traction piece 10 is connected to the lower part of the inner side wall of the second side wall 04. A pull strap 11 is provided on the side of the pull plate 09 near the second side wall 04. When the pull plate 09 is lifted upward by the pull strap 11, the flexible traction piece 10 drives the second side wall 04 and the first side wall 03 to move closer to each other. The connection between the first side wall 03 and the second side wall 04 extends outward. The first side wall 03 unfolds inward along the first vertical crease 05, and the second side wall 04 unfolds inward along the second vertical crease 06.

[0024] The box body 01 is formed by the first side wall 03 and the second side wall 04. The heart-shaped receiving groove is the space formed between the first side wall 03 and the second side wall 04 when the box body 01 is unfolded. This space is used to hold gifts (such as chocolates, jewelry, etc.).

[0025] The ends (both ends) of the first side wall 03 are connected to the ends (both ends) of the second side wall 04. After the connection, they form a heart-shaped space (i.e., a heart-shaped receiving groove). Divided by the line connecting the two ends, when the box 01 is unfolded, the first side wall 03 is half of the heart shape and the second side wall 04 is the other half of the heart shape. The first side wall 03 and the second side wall 04 are arranged symmetrically (with the line connecting the two ends as the line of symmetry).

[0026] The first sidewall 03 and the second sidewall 04 are integrally connected and arranged symmetrically to form a complete and sturdy three-dimensional heart-shaped container for holding gifts (such as chocolates and jewelry). Creases are provided at the joint to improve folding efficiency and accuracy.

[0027] It is understandable that a connecting component, such as a hinge or hinge, can be provided at the connection between the first side wall portion 03 and the second side wall portion 04. In this case, the first side wall portion 03 and the second side wall portion 04 are two independent components.

[0028] The first vertical crease 05 on the first sidewall portion 03 and the second vertical crease 06 on the second sidewall portion 04 are symmetrically distributed about the axis of symmetry of the heart-shaped receiving groove. The crease is a pre-set weakening line formed by pressing, die-cutting, or other methods on a substrate such as cardboard or cardboard, guiding the material to bend precisely along the line.

[0029] The lid 02 includes a first cover plate 07 connected to the first side wall portion 03 and a second cover plate 08 connected to the second side wall portion 04, the free ends of which can overlap each other. The overlap method can be a simple overlap, or it can be equipped with fixing elements such as magnetic tabs and buckles.

[0030] The active end refers to the end that is not connected to the box body 01, such as the end of the first cover plate 07 that is not connected to the first side wall portion 03.

[0031] Pull plate 09 is a plate set at the bottom of the heart-shaped receiving groove, and its outline matches the bottom outline of the heart-shaped receiving groove. When the box body 01 is unfolded, pull plate 09 serves as the bottom plate of the receiving groove, providing support; when folded, pull plate 09 becomes a component that drives the box body 01 to fold (in cooperation with flexible traction piece 10).

[0032] The flexible traction piece 10 is a piece of flexible material (such as a fabric strip, a plastic sheet, or a paper tongue cut from a substrate), with its two ends connected to the lower surface of the pull plate 09 and the lower part of the inner sidewall of the second sidewall 04, respectively.

[0033] During the folding process, the flexible traction piece 10 converts the upward movement of the pull plate 09 into an inward pulling force on the second side wall 04, ensuring that the movement of the second side wall 04 is synchronized with the movement of the pull plate 09.

[0034] The pull strap 11 is a gripping strap or protruding paper tongue located on the side of the pull plate 09 near the second side wall 04. It allows the user to easily apply force to lift the pull plate 09 and start the folding process.

[0035] When this application changes from the unfolded state (heart-shaped receiving slot) to the folded state: the user hooks or pulls the pull strap 11 and applies an upward pulling force. At this time, the pull plate 09 is lifted upward, and the pull plate 09 rises, pulling the flexible traction piece 10 connected to it. The flexible traction piece 10 then pulls the lower part of the second side wall 04 inward (towards the center of the box 01). Finally, the two side walls are folded flat, the connection point protrudes, and the entire box 01 transforms from a three-dimensional heart shape into a flat, approximately two-dimensional shape mainly composed of the connecting plate 12 and the side walls, greatly reducing the thickness and space occupied.

[0036] When fully folded, the heart-shaped receiving groove is compressed and contracted, and the pull plate 09 is in a vertical state. The pull plate 09 is held by the first side wall portion 03 and the second side wall portion 04 on both sides. The end of the pull plate 09 (the end opposite to the position of the pull strap 11) is flush with the lower surface of the first side wall portion 03 and the lower surface of the second side wall portion 04. The first cover plate 07 and the second cover plate 08 are also held by the pull plate 09 on both sides respectively. The first cover plate 07 is parallel to the first side wall portion 03, and the second cover plate 08 is also parallel to the second side wall portion 04.

[0037] It should be noted that, in the unfolded state, the area where the two first vertical creases 05 on the first side wall 03 are located is outwardly protruding. During the folding process, the outwardly protruding area will gradually shrink inward (towards the location of the second side wall 04), and the connection between the two ends of the first side wall 03 and the second side wall 04 will gradually move outward (away from the center of the heart-shaped receiving groove).

[0038] In the unfolded state, the pull plate 09 is located (parallel to) the bottom of the heart-shaped receiving groove. The edge of the pull plate 09 is in contact with the first side wall portion 03 and the second side wall portion 04. When the pull plate 09 is not pulled up, the first side wall portion 03 and the second side wall portion 04 are supported apart by the pull plate 09.

[0039] In this embodiment, the first sidewall 03 and the second sidewall 04 form a box body 01, and the first cover plate 07 and the second cover plate 08 form a box cover 02. For the box body 01, three parallel first vertical creases 05 are provided on the first sidewall 03, and three parallel second vertical creases 06 are provided on the second sidewall 04. The first sidewall 03 and the second sidewall 04 are connected to each other and form a heart-shaped receiving groove. A pull plate 09 is provided at the bottom of the heart-shaped receiving groove. The outline of the pull plate 09 matches the bottom outline of the heart-shaped receiving groove. The pull plate 09 is connected to the second sidewall 04 by a flexible traction piece 10, and a pull strap 11 is provided on the pull plate 09. When the pull plate 09 is lifted upward by the pull strap 11, the flexible traction piece 10 drives the second sidewall 04 and the first sidewall 03 to move closer to each other, so as to realize the folding of the box body 01. Therefore, compared with traditional integrated structures or top and bottom cover forms, this application has a folding function. When in use, it unfolds to form a heart-shaped receiving slot. When not in use, the heart-shaped receiving slot is folded down by the pull plate 09. The first side wall 03 and the second side wall 04 come together to achieve folding. During transportation and storage, after being folded and stored, it can transform from a fixed three-dimensional form into a flat, near two-dimensional form when not in use, which can reduce the occupied area, improve space utilization, and reduce storage costs.

[0040] Please continue reading. Figure 4 and Figure 9In an optional embodiment, a connecting plate 12 is provided at the bottom of the heart-shaped receiving groove. The connecting plate 12 is movably connected to the first side wall portion 03 and the second side wall portion 04 respectively. A third crease is provided on the connecting plate 12, and the third crease is aligned with the axis of symmetry of the heart-shaped receiving groove.

[0041] The connecting plate 12 is a plate-like structure set at the bottom of the heart-shaped receiving groove. The connecting plate 12 is movably connected to the first side wall 03 and the second side wall 04 through folds or other means (that is, it is not fixed and can move relative to each other).

[0042] The third crease is a crease pressed onto the connecting plate 12. The third crease is aligned with the axis of symmetry of the heart-shaped receiving groove, that is, it divides the connecting plate 12 into left and right parts along the central axis of the heart. When the sidewalls fold inward, the bottom can also deform accordingly, avoiding stress concentration and folding resistance caused by the bottom material's inability to bend.

[0043] During the folding process, the third crease of the connecting plate 12 moves upward, causing both sides of the connecting plate 12 to fold downward along the third crease. The connecting plate 12 at the bottom not only supports the pull plate 09 when unfolded, but also limits the distance between the first side wall portion 03 and the second side wall portion 04 to prevent over-unfolding and maintain the heart-shaped shape when unfolded.

[0044] In this optional embodiment, a hollow area is provided at the center of the connecting plate 12, and the area of ​​the hollow area is smaller than the area of ​​the pull plate 09.

[0045] In this embodiment, the center of the connecting plate 12 is hollowed out. The edge of the hollowed-out area is aligned with the line connecting the first vertical crease 05 and the second vertical crease 06. That is, the area formed by connecting the first vertical crease 05 and the second vertical crease 06 is the same size as the hollowed-out area on the connecting plate 12.

[0046] By creating a hollowed-out area, interference-free movement space is provided for the pull plate 09. When the pull plate 09 is pulled upwards for folding, if the connecting plate 12 below the pull plate 09 were a complete flat surface, it might rub against, squeeze, or even jam with the moving pull plate 09. This hollowed-out area reduces interference with the movement of the pull plate 09, ensuring the reliability of folding.

[0047] Please continue reading. Figure 3 and, Figure 6 and Figure 8 In an optional embodiment, an abutment plate 13 is provided on the lower surface of the first cover plate 07. The abutment plate 13 extends horizontally toward the second cover plate 08 and is used to support the second cover plate 08.

[0048] The first cover plate 07 matches the "semi-heart" shape that the first side wall portion 03 surrounds when unfolded. An abutment plate 13 is fixed on the side of the first cover plate 07 facing the second cover plate 08. The abutment plate 13 is located on the lower surface of the first cover plate 07 and extends horizontally toward the second cover plate 08.

[0049] It should be noted that the abutment plate 13 can be integrally formed with the first cover plate 07, or it can be an additional component.

[0050] During the deployment phase, the first cover plate 07 is placed over the "semi-heart-shaped" area surrounded by the first side wall portion 03, and the second cover plate 08 is placed over the "semi-heart-shaped" area surrounded by the second side wall portion 04. The side of the second cover plate 08 facing the first cover plate 07 overlaps with the abutment plate 13, and the abutment plate 13 supports the second cover plate 08.

[0051] In this optional embodiment, a first magnetic block 14 is provided on the abutment plate 13, and a second magnetic block 15 is provided on the second cover plate 08. The second magnetic block 15 cooperates with the first magnetic block 14 to attract the second cover plate 08 onto the abutment plate 13.

[0052] The first magnetic block 14 is embedded or fixed to the lower surface of the abutment plate 13, and the second magnetic block 15 is embedded or fixed to the inner surface of the second cover plate 08 (or the side facing the first cover plate 07). The two magnetic blocks are positioned opposite each other. In one possible implementation, both the first magnetic block 14 and the second magnetic block 15 are permanent magnets, and the second cover plate 08 is attracted to the abutment plate 13 by the attraction of the permanent magnets. In another possible implementation, a combination of a permanent magnet and an iron sheet can also be used. However, it should be noted that the positions of the first magnetic block 14 and the second magnetic block 15 are designed so that they face each other when the lid 02 is closed.

[0053] In this embodiment, when the second cover plate 08 approaches the abutment plate 13, the magnetic fields of the first magnetic block 14 and the second magnetic block 15 interact, generating a strong attractive force. This attractive force guides the second cover plate 08 to move until it reaches the position of minimum magnetic resistance, i.e., a completely aligned and closed state, and remains stable in this position. The process does not require manual alignment or fastening by the user.

[0054] In this optional embodiment, a handle 16 is provided on the side of the second cover plate 08 near the second magnet 15.

[0055] The handle 16 is a raised structure located on the side of the second cover plate 08 near the second magnet 15. It can be a pre-cut semi-circular finger hole, an adhesive ribbon loop, or an inwardly recessed groove.

[0056] When the handle 16 is a ribbon loop, one end of the ribbon loop is connected to the lower surface (or side) of the second cover plate 08, and the other end protrudes upward through the gap between the second cover plate 08 and the first cover plate 07, so that the user can grasp the ribbon loop.

[0057] Users can naturally hook or press the handle 16 with their fingertips to easily apply an upward force to overcome the magnetic force, achieving easy and elegant opening. This avoids creases, damage, or deformation caused by users forcibly prying or pressing the center of the lid 02 due to a lack of leverage.

[0058] The first cover 07 and the second cover 08 are independent of each other. When the user pulls up the handle 16, the second cover 08, which is in a closed state, is opened, and then the first cover 07 can be manually lifted.

[0059] Unlike the method described above where the second cover plate 08 is fixed to the abutment plate 13 by magnetic attraction, which can still detach if there is significant vibration during transportation, in this optional embodiment, to improve the stability of the connection, the second cover plate 08 and the first cover plate 07 are connected by a snap-fit.

[0060] In this embodiment, the second cover plate 08 still overlaps the abutment plate 13, and the buckle is set on the abutment plate 13 or on the first cover plate 07. When the second cover plate 08 overlaps the abutment plate 13, the buckle is achieved.

[0061] Buckles include hook-type buckles, post-hole type buckles, and snap-on buckles, etc. The specific type to be selected is not limited here, but should be based on what is actually feasible.

[0062] In this optional embodiment, the edge of the first cover plate 07 is provided with a horizontally outwardly extending outer edge 17, which is used to abut against the top end of the first sidewall portion 03.

[0063] The outer edge 17 refers to a ring or section of plate-like structure extending horizontally outward from the edge of the first cover plate 07. When the lid 02 is closed, this outer edge 17 abuts tightly against the top of the first side wall portion 03, which is equivalent to adding a reinforcing ring or support frame at the opening of the box body 01. This effectively prevents the first side wall portion 03 from collapsing inward under lateral pressure, making the entire box body 01 more robust and upright.

[0064] In an optional embodiment, the box body 01 is made of corrugated cardboard or grey board.

[0065] In an optional embodiment, the first crease and the second crease are made using an indentation process.

[0066] Creasing, also known as "debossing" or "crease marking," involves pressing a groove into the surface of cardboard using a steel wire on a die, without completely cutting the material fibers. This groove is called a "crease."

[0067] An indentation creates a V-shaped or U-shaped groove on the material surface, significantly reducing the cross-sectional area at that point. When an external force attempts to bend the cardboard, the stress concentrates dramatically at this location where the cross-section suddenly shrinks, far exceeding that in other areas. Therefore, the material's yielding and bending preferentially and precisely occur along this pre-designed indentation line, resulting in a controlled and aesthetically pleasing fold.

[0068] In this application, the interior of box 01 (heart-shaped receiving slot) can be designed with corresponding linings and dividers according to different gift needs. The lining is made of soft materials, such as sponge or velvet, to protect the gifts; the dividers are used to separate different gifts and prevent them from colliding with each other.

[0069] The exterior of the box body 01 (outer side of the first side wall 03, outer side of the second side wall 04, etc.) can be decorated using printing, hot stamping, embossing, and other processes to enhance the aesthetics and perceived quality of the gift box. Furthermore, different patterns and texts, such as brand logos and greetings, can be customized according to customer needs.

[0070] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
