[0044] Existing single bottled or canned products often have no special packaging when purchased individually, which is inconvenient for consumers to carry. At the same time, when the above products are given as gifts, there is no individual packaging, which cannot meet the requirements of consumers for giving as gifts. Existing packaging for bottled or canned products mostly uses an ordinary cardboard box to package several of the above bottled or canned products, and does not have a display effect.

[0045] Embodiment 1

[0046] To solve the above problems, as Figure 1 shown, in this embodiment, a portable packaging box is provided. The portable packaging box provided in this embodiment is mainly for the packaging and display of a single product. This portable packaging box can also be used to package bottled products such as beer, liquor and beverages, or canned products such as canned beer and beverages. This portable packaging box is mainly used to package a single product, and can also package two, three or four products. When the products are placed, they are placed in a single row or a double row, as long as the structural strength of this packaging box can bear the weight of the products. This packaging box in this embodiment is mainly used for the outer packaging of craft beer.

[0047] Specifically, the portable packaging box includes a base 1, two first side plates 2, and two second side plates 3. Among them, a receiving groove 10 matching the shape of the bottom of the product to be packaged is provided on the base 1. The shape of the receiving groove 10 is determined according to the shape of the bottom of the product to be packaged. In this embodiment, the receiving groove 10 is a circular groove. One opposite side of the base 1 is respectively connected with a first side plate 2. One second side plate 3 is respectively provided on the other opposite sides of the base 1. Each second side plate 3 is inserted into the two first side plates 2 and is snap-connected to the two first side plates 2. After snap-connection, the upper ends of the two second side plates 3 are relatively close to each other.

[0048] In this embodiment, the product to be packaged is placed in the receiving groove 10, and the receiving groove 10 fixes the bottom of the product. At this time, the product can be displayed. Also, because the two first side plates 2 are located on one opposite side of the base 1, and the two second side plates 3 are located on the other opposite sides of the base 1, and the second side plates 3 are simultaneously connected to the two first side plates 2. After the four side plates are connected to each other, the product is located between the four side plates, and the upper ends of the two second side plates 3 are relatively close to each other, serving as a handle end, which is convenient for consumers to carry by hand. The first side plates 2 and the second side plates 3 are connected in a snap-fit manner. During the product display process, through the assembly of the second side plates 3 and the first side plates 2, it can be taken away by consumers immediately. This packaging is convenient, fast, and beautiful. Single-bottle or single-can high-end products are more beautiful as gifts under this packaging, meeting the needs of consumers. When this packaging is not in use, the second side plates 3 are detachable, which is convenient for recycling. At the same time, because the above-mentioned first side plates 2 and second side plates 3 are connected in a snap-fit manner, and the first side plates 2 are connected to the base 1. Before folding, the base 1 and the first side plates 2 are regarded as a whole, and the second side plates 3 are regarded as a part, and they are stacked and transported separately, which is convenient for transportation and occupies little space.

[0049] This type of packaging box can be used for exhibition and sales, making it possible to purchase individually or in small quantities, which can greatly increase the sales volume of craft beer in the store. At the same time, the two second side plates 3 as a handle structure also make it more convenient for sellers to carry and transport the product.

[0050] Further specifically, as Figure 2 shown, the first side plate 2 and the base 1 are integrally formed. The first side plate 2 and the base 1 are unfolded and stacked during transportation, which is convenient for transportation. This packaging box selects B-flute corrugated cardboard as the packaging material, which has the advantages of environmental protection, easy recycling, and easy forming.

[0051] As Figure 2 shown, Figure 2 is the unfolded plan view of the base 1 and the first side plate 2. The specific structures of the first side plate 2 and the base 1 will be described below.

[0052] The base 1 includes a bottom plate 11. The first side plates 2 are connected to two opposite sides of the bottom plate 11. On the other two opposite sides of the bottom plate 11, a first folding plate 12 and a second folding plate 13 are sequentially connected. The first folding plate 12 is folded upward by 90°. After being folded, the second folding plate 13 is located above the bottom plate 11 and parallel to the bottom plate 11. A round hole 131 is provided on the second folding plate 13. The round holes 131 on the two second folding plates 13 and the bottom plate 11 form the above-mentioned receiving groove 10.

[0053] In addition, to ensure the stability of the above-mentioned first folding plate 12 and second folding plate 13, a socket 132 is provided on one of the second folding plates 13, and a tongue 133 that can be inserted and fixed in the socket 132 is provided on the other second folding plate 13. In this embodiment, the tongue 133 is located at the end of the second folding plate 13. After the position of the tongue 133 is fixed, the position of the socket 132 is determined.

[0054] A clamping plate 21 is further provided at the upper end of the above-mentioned first side plate 2. The clamping plate 21 is configured to fix the upper part of the product.

[0055] More specifically, to reduce the weight of the overall structure without adding other structures, a hook-shaped opening hole 211 is provided on the clamping plate 21. The upper part of the product is located within the hook-shaped opening hole 211. In this embodiment, the two hook-shaped opening holes 211 provided on the clamping plate 21 enclose a circular hole, and the upper part of the product is located within the circular hole for fixing the upper part of the product. This packaging box has a simple structure, does not require the use of adhesives for assembly and forming, can be shipped flat, is convenient to use and recycle, and saves a large amount of transportation and storage costs.

[0056] Continue to refer to Figure 2 and Figure 3 shown, the specific structure of the clamping of the above-mentioned first side plate 2 and second side plate 3 will be described in detail.

[0057] Two card slots 22 are provided on each first side plate 2. A first vertical through slot 31 is provided on the second side plate 3. The first side plate 2 and the second side plate 3 are hook-connected through the card slots 22 and the first vertical through slot 31.

[0058] Specifically, the specific structure of the first vertical through slot 31 is as Figure 2 shown. Figure 2 and Figure 3 The card slot 22 in Figure 3As shown, the included angle between the first inclined slot 222 and the second vertical through slot 221 is α, and the value of this included angle α is determined according to factors such as the size of the second side plate 3, and the position and size of the first vertical through slot 31 on the second side plate 3. As Figure 3 shown in the cross-hatched area of Figure 3 , there are first avoidance areas 223 on both sides of the second vertical through slot 221. The first avoidance areas 223 are connected to the first inclined slot 222. The first avoidance areas 223 enable the second side plate 3 located in the second vertical through slot 221 and in a vertical state to rotate into the first inclined slot 222. Specifically, in this embodiment, the first avoidance area 223 is a sector.

[0059] The card slot 22 further includes a second inclined slot 224. The second inclined slot 224 is located below the first inclined slot 222 and the two are not connected. Specifically, the second inclined slot 224 extends downward from the side of the first side plate 2 to communicate with the second vertical through slot 221. The second inclined slot 224 is located below the first avoidance area 223. The angle between the second inclined slot 224 and the second vertical through slot 221 is β, and the value of the angle between the two is determined according to actual needs. There are second avoidance areas 225 on both sides of the second vertical through slot 221. The second avoidance areas 225 are connected to the second inclined slot 224. In this embodiment, the second avoidance area 225 is a sector. The sizes of the second avoidance areas 225 provided on both sides of the second vertical through slot 221 are not necessarily the same. The size of the first avoidance area 223 is determined according to the size and position of the first vertical through slot 31 into which the second side plate 3 is inserted, and the value of the above-mentioned angle β. The second avoidance areas 225 enable the second side plate 3 inserted from the second inclined slot 224 to rotate into the second vertical through slot 221 and be in a vertical state.

[0060] Specifically, in this embodiment, the path for the second side plate 3 to be inserted into the first side plate 2 is as Figure 3 shown by the arrow marked in the card slot 22 at the left side in Figure 3 . Taking the arrow marked in the figure as an example for illustration. The second side plate 3 is inserted into the second inclined slot 224 (shown as a in the figure), and after rotating clockwise in the second avoidance area 225 (shown as b in the figure), the second side plate 3 becomes vertical. At this time, the part of the first side plate 2 located above the second inclined slot 224 is inserted into the first vertical through slot 31 of the second side plate 3. The second side plate 3 continues to rotate in the vertical direction by using the first vertical through slot 31 and the second vertical through slot 221 (shown as c in the figure). Then, it rotates clockwise in the first avoidance area 223 (shown as d in the figure) and continues to move obliquely upward along the first inclined slot 222 (shown as e in the figure), realizing the two second side plates 3 moving closer to each other.

[0061] More specifically, please refer to Figure 2, handle holes 32 or portable handles are provided on the second side plates 3. In this embodiment, handle holes 32 are provided on the second side plates 3. After the two second side plates 3 are moved closer to the middle, the handle holes 32 facilitate consumers to carry the product. In other embodiments, a detachable strap may also be installed at the upper end of the second side plate 3 for convenient hand carrying. When not in use, it is convenient to disassemble.

[0062] In summary, as Figure 1 shown, the packaging box is assembled from two parts, a box body part composed of a base 1 and a first side plate 2, and two second side plates 3 with handle functions. The circular accommodating groove 10 on the base 1 and the circular hole formed by the hook-shaped opening holes 211 provided on the clamping plate 21 are grooved and fixed according to the size of the wine bottle body. There are hollowed-out card slots 22 on the two first side plates 2 on both sides, serving as tracks for installing the second side plates 3 and changing the shape of the packaging box. The two second side plates 3 are combined and fixed with the box body part through the tracks, and then enter two different shapes through the card slots 22 as tracks. This variably and interactively packaged box can bring consumers a different box-opening experience, arouse consumers' curiosity, and increase product sales. The overall shape of the packaging box is simple and generous, with a modern sense of line. The rounded corners at the outer edges also break the convention of the square packaging, giving the packaging an affinity and making it more acceptable to consumers. At the same time, the normal use of the functional structure of this exhibition packaging does not require the use of adhesives. All connection parts use snap structures. This unique design facilitates its assembly and recycling, and is very environmentally friendly and saves production costs. It is also very convenient to use and assemble.

[0063] Embodiment 2

[0064] Based on the above Embodiment 1, the difference from the above Embodiment 1 is that the structure of the above card slot 22 is as Figure 4 shown.

[0065] Specifically, as Figure 4 shown, the card slot 22 includes a second vertical through slot 221 and a first inclined slot 222. Among them, the second vertical through slot 221 is arranged in the vertical direction, and the opening of the second vertical through slot 221 faces vertically downward. One end of the first inclined slot 222 extends upward from the second vertical through slot 221 in the direction close to the vertical center line of the first side plate 2. As Figure 4 shown, the included angle between the first inclined slot 222 and the second vertical through slot 221 is α, and the value of this included angle α is determined according to factors such as the size of the second side plate 3, the position and size of the first vertical through slot 31 on the second side plate 3, etc. Figure 4The first avoidance area 223 in the hatched area shown, there are first avoidance areas 223 provided on both sides of the second vertical through groove 221. The first avoidance area 223 is communicated with the first inclined slot 222. The first avoidance area 223 enables the second side plate 3 located in the second vertical through groove 221 and in a vertical state to rotate into the first inclined slot 222. Specifically, in this embodiment, the first avoidance area 223 is fan-shaped.

[0066] Figure 4 The direction of the arrow shown in the figure is the movement path of the second side plate 3. Taking the arrow marked in the figure as an example for illustration, the second side plate 3 is inserted into the second vertical through groove 221. At this time, the part of the first side plate 2 located above the second inclined slot 224 is inserted into the first vertical through groove 31, so that the first side plate 2 and the second side plate 3 are in a perpendicular state. The second side plate 3 moves upward in the second vertical through groove 221 by using the first vertical through groove 31 (as shown by a in the figure), then rotates clockwise in the first avoidance area 223 (as shown by b in the figure), and continues to move obliquely upward along the first inclined slot 222 (as shown by c in the figure), realizing the two second side plates 3 moving closer to the middle.

[0067] Embodiment Three

[0068] On the basis of the above Embodiment One, the difference from the above Embodiment One is that the structure of the above card slot 22 is as Figure 5 shown.

[0069] The card slot 22 includes a second vertical through groove 221 and a first inclined slot 222. Among them, the second vertical through groove 221 is arranged in the vertical direction. One end of the first inclined slot 222 extends upward from the second vertical through groove 221 in the direction close to the vertical center line of the first side plate 2. As Figure 5 shown, the included angle between the first inclined slot 222 and the second vertical through groove 221 is α, and the value of this included angle α is determined according to factors such as the size of the second side plate 3, and the position and size of the first vertical through groove 31 on the second side plate 3. As Figure 5 the first avoidance area 223 in the hatched area shown, there are first avoidance areas 223 provided on both sides of the second vertical through groove 221. The first avoidance area 223 is communicated with the first inclined slot 222. The first avoidance area 223 enables the second side plate 3 located in the second vertical through groove 221 and in a vertical state to rotate into the first inclined slot 222.

[0070] The card slot 22 further includes a second inclined slot 224 which extends downward from the side of the first side plate 2 to communicate with the second vertical through slot 221. A second avoidance area 225 is provided on one side of the second vertical through slot 221 close to the vertical center line of the first side plate 2. The second avoidance area 225 communicates with the second inclined slot 224, and the opening of the second inclined slot 224 is located above the second avoidance area 225. The second avoidance area 225 enables the second side plate 3 inserted from the second inclined slot 224 to rotate into the second vertical through slot 221 and be in a vertical state.

[0071] Specifically, in this embodiment, the path of the second side plate 3 inserted into the first side plate 2 is as Figure 5 shown by the arrow in the figure. Taking the arrow marked in the figure as an example, the second side plate 3 is inserted into the second inclined slot 224 (shown as a in the figure), and after rotating clockwise in the second avoidance area 225 (shown as b in the figure), the second side plate 3 becomes vertical. At this time, the A area of the first side plate 2 is inserted into the first vertical through slot 31 of the second side plate 3, and the second side plate 3 continues to move upward in the vertical direction by using the first vertical through slot 31 and the second vertical through slot 221 (shown as c in the figure). Then, it rotates clockwise in the first avoidance area 223 (shown as d in the figure) and continues to move obliquely upward along the first inclined slot 222 (shown as e in the figure), realizing the two second side plates 3 moving closer to the middle. This design can reduce the displacement of the second side plate 3 in the vertical direction. At the same time, it can also reduce the lengths of the first vertical through slot 31 and the second vertical through slot 221, making the overall structure easier to process, saving processing time, and reducing processing techniques.

[0072] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention.
