DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] Because the related technology has a technical problem that when taking out a large-screen product from a packaging box, the upper cover needs to be removed first, that is, the upper cover needs to be lifted as a whole to a position higher than the product. However, the large screen has a certain height. In the process of removing the upper cover, the upper cover is easy to touch the large-screen product, thereby easily causing the large screen to tip over.

[0029] In order to solve the above technical problems, this embodiment provides a packaging container, which is matched with electronic products, specifically for packaging electronic products. The electronic products can be televisions, monitors, electronic blackboards or other large-screen electronic products that need to be protected by external packaging. Figure 1 The packaging container includes a first box body 100 and a second box body 200, and the first box body 100 and the second box body 200 are usually made of corrugated paper.

[0030] See also Figure 1-2 The first box body 100 includes a first bottom plate 110 and a plurality of first side plates 120, each of which is connected to the first bottom plate 110. When the first box body 100 is made of corrugated paper, the first bottom plate 100 and the plurality of first side plates 120 are planar structures after the same cardboard is cut by a die-cutting device. The connection between the first bottom plate 100 and the plurality of first side plates 120 has an indentation line. It can be understood that when used for electronic product packaging, the flat cardboard is folded according to the indentation lines at different parts to obtain the first box body 100 with the first installation cavity 100a. The first installation cavity 100a forms a first opening 100b on the upper surface of the first box body 100, and the first opening 100b is opposite to the first bottom plate 100. Through the first opening 100b, it is convenient for users to put electronic products into the first installation cavity 100a, and the first installation cavity 100a is used to package the electronic product.

[0031] See also Figure 1-2The second box body 200 includes a second bottom plate 210 and a plurality of second side plates 220, each of which is connected to the second bottom plate 210. When the second box body 200 is also made of corrugated paper, the manufacturing steps are the same as those of the first box body 100. The second bottom plate 210 and the plurality of second side plates 220 are enclosed and define a second installation cavity 200a. The second installation cavity 200a forms a second opening 200b on the lower surface of the second box body 200, and the second opening 200b is opposite to the second bottom plate 210. Through the second opening 200b, when the second box body 200 is sleeved on the first box body 100, the remaining part of the electronic product can enter the second installation cavity 200a through the second opening 200b. The second box body 200 cooperates with the first box body 100 to carry out all-round packaging of the electronic product.

[0032] Part of at least one of the second side panels 220 can be expanded outward, so that the second box body 200 can rotate around the first box body 100 and form an escape area for taking out electronic products.

[0033] In this embodiment, since the second box body 200 is mounted on the first box body 100, the second box body 200 has a different position relative to the first box body 100. A portion of at least one second side panel 220 of the second box body 200 can be expanded outward, so that the second box body 200 rotates around the first box body 100 and forms an escape area for taking out electronic products. In this way, there is no need to lift the second box body 200 as a whole to a position higher than the product, and the electronic product can be exposed, thereby reducing the possibility of the second box body 200 contacting the electronic product, thereby reducing the risk of the electronic product tipping over due to contact.

[0034] In accordance with the above, the plurality of first side panels 120 and the plurality of second side panels 220 are distributed in a one-to-one correspondence, that is, each first side panel 120 corresponds to a first second side panel 220, and the first side panel 120 and the corresponding second side panel 220 are arranged opposite to each other, and the two are almost close together, and the gap between the two is approximately between 1 mm and 4 mm. In this way, if the first box body 100 is set on the second box body 200, the first box body 100 will also be almost close to the second box body 200, preventing the second box body 200 from shaking relative to the first box body 100 during transportation, thereby ensuring the stability of the overall structure. Secondly, the close fit between the first side panel 120 and the second side panel 220 reduces the friction and collision caused by shaking, and can effectively protect electronic products.

[0035] In order to prevent the second box body 200 from falling off from the first box body 100, see Figure 1-3A pair of opposite first side panels 120 has at least one first slot 120a, and a second side panel 200 opposite to the first side panel 120 has at least one second slot 220a. The packaging container also includes at least one connecting member 300, which can be detachably inserted into the first slot 120a and the second slot 220a to connect the first box body 100 and the second box body 200.

[0036] The cross-sections of the first slot 120a and the second slot 220a can be circular holes, elliptical holes, rectangular holes, triangular holes, diamond holes, etc. In this embodiment, it is preferred that the cross-sections of the first slot 120a and the second slot 220a are the same. After the connecting piece 300 is inserted into the first slot 120a and the second slot 220a, the connecting piece 300 fits tightly with the side walls forming the first slot 120a and the side walls forming the second slot 220a, which can prevent the connecting piece 300 from falling off from the first slot 120a and / or the second slot 220a.

[0037] In the embodiment of the present application, there may be a plurality of first slots 120a and a single second slot 220a, see Figure 2-3 In this embodiment, two first slots 120a are provided on a first side plate 120, and two second slots 220a are provided on a second side plate 220 opposite to the first side plate 120 for exemplary description:

[0038] The first side plate 120 includes two first slots 120a, the second side plate 220 has two second slots 220a, the two first slots 120a are spaced apart along the depth of the first installation cavity 100a, the two second slots 220a are spaced apart along the depth of the second installation cavity 200a, and the second box 200 has a first position and a second position;

[0039] If the second box body 200 is in the first position, the two first slots 120a correspond to the two second slots 220a respectively, and the first box body 100 is completely covered in the second installation cavity 200a.

[0040] The first slot 120 at the lower end of the first side panel 120 and the first slot 120 at the lower end of the second side panel 220 are in the same plane, and the first slot 120 at the upper end of the first side panel 120 and the first slot 120 at the upper end of the second side panel 220 are in the same plane, wherein the first slot 120a and the corresponding second slot 220a form a connecting hole, thus forming two connecting holes, and two connecting members 300 are respectively inserted into the two connecting holes, at this time, the first box body 100 is completely covered in the second installation cavity 200a, is not easy to shake, and has higher stability.

[0041] If the second box 200 is in the second position, the second slot 220a at the lower end of the second side plate 220 and the first slot 120a at the upper end of the first side plate 120 are in the same plane, and the first box 100 is partially covered in the second installation cavity 200a.

[0042] In this state, since there is only one connecting hole formed by the first slot 120a and the corresponding second slot 220a, the second box body 200 can rotate around the axis formed by the connecting piece so that part of the second side panel 220 can be expanded outward and form an escape area for taking out electronic products.

[0043] The user can first take out the connecting member 300 from the first slot 120a and the second slot 220a, and then adjust the position of the second box 200 relative to the first box 100 according to actual conditions, so that the second box 200 is in the first position or the second position.

[0044] In some other embodiments, there are two first slots 120a on a first side plate 120, and there is one second slot 220a on a second side plate 220 opposite to the first side plate 120. For example, as shown in FIG.

[0045] The first side plate 120 includes two first slots 120a, the second side plate 220 has a second slot 220a, the two first slots 120a are spaced apart along the depth of the first installation cavity 100a, and the second box body 200 has a first position and a second position;

[0046] If the second box body 200 is in the first position, the second slot 220a and the first slot 120a at the lower end of the first side plate 120 are in the same plane, and the first box body 100 is completely covered in the second installation cavity 200a.

[0047] If the second box body 200 is in the second position, the second slot 220a and the first slot 120a at the upper end of the first side plate 120 are in the same plane, and a portion of the first box body 100 is covered in the second installation cavity 200a.

[0048] In this embodiment, since the second side plate 220 has only one second slot 220a, the processing procedures are reduced. In addition, the user can connect the first box body 100 and the second box body 200 using only one connector 300, thereby shortening the installation steps and improving the installation efficiency.

[0049] It should be understood that, since at least one portion of the second side plate 220 can be expanded outward, that is, one portion of the second side plate 220 can be expanded outward, or two or more portions of the second side plates 220 can be expanded outward.

[0050] If a portion of the second side panel 220 can be expanded outward, when the second box body 200 is in the first position, the edge of the second side panel 220 facing the second opening is closer to the ground or closer to the supporting surface supporting the first box body 100. At this time, the remaining second side panels 220 are blocked by the ground or the supporting surface, and the second box body 200 cannot rotate around the first box body 100, and an escape area for taking out electronic products cannot be formed.

[0051] When the second box body 200 is in the second position, the edge of the second side panel 220 facing the second opening is far away from the ground or the supporting surface supporting the first box body 100, and the ground or the supporting surface will not interfere with the rotation of the second box body 200. After the second side panel 220 is partially unfolded outward, the second box body 200 can rotate around the first box body 100, so that an escape area for taking out electronic products can be formed at the upper end of the first opening 100b.

[0052] If parts of multiple second side panels 220 can be expanded outward, taking a pair of oppositely arranged second side panels 220 as an example, if the second box body 200 is in the first position, since parts of the two second side panels 220 can be expanded outward, when the second box body 200 rotates toward the side of one of the two second side panels 220, part of the other second side panel 220 can be expanded outward, avoiding contact with the ground or the supporting surface, and does not affect the rotation of the second box body 200. However, it should be noted that during the rotation process, electronic products must not come into contact with the second side panels 220.

[0053] See also Figure 2-3 In some embodiments, the part of the second side panel 220 that can be unfolded outward forms a folding portion 221, and the folding portion 221 has a packaging state and an unfolding state. In the unfolding state, the folding portion 221 unfolds outward to facilitate users to take out or put in electronic products from the first box body 100; in the packaging state, the connecting member 300 detachably connects the folding portion 221, the first side panel 120 and the second side panel 220 to limit the unfolding of the folding portion 221, so that the second box body 200 cooperates with the first box body 100, thereby completing the packaging of the electronic products and facilitating storage and transportation.

[0054] It should be understood that while restricting the unfolding of the folding portion 221, the rotation of the second box body 200 is also restricted. At this stage, the second side panel 220 is in contact with the first side panel 120, ensuring the stability of the overall structure.

[0055] Please continue reading Figure 2-3A pair of edges of the folding portion 221 are connected to a connecting portion 222, and the connecting portion 222 has at least one third slot 222a. The connecting member 300 can be detachably inserted into the first slot 120a, the second slot 220a and the third slot 222a to limit the folding portion 221 from unfolding.

[0056] By inserting the connecting member 300 into the first slot 120a, the second slot 220a and the third slot 222a, the folding portion 221 is restricted from unfolding, and the rotation of the second box body 200 is also restricted. At this stage, that is, when in the packaging state, the connecting portion 222 is located between the second side panel 220 and the opposite first side panel 120, and is tightly fitted with the second side panel 220 and the first side panel 120, thereby ensuring the stability of the overall structure.

[0057] The third slot 222a on a connecting portion 222 can be one or more. When there are more than one third slot 222a on a connecting portion 222, and there are more than one first slot 120a and more than one second slot 220a, and the more than one first slot 120a, the more than one second slot 220a and the more than one third slot 222a can form a plurality of connecting holes, then the entire structure can be made more stable by inserting a plurality of connecting members 300.

[0058] In this embodiment, a folding indentation line is provided between the folding portion 221 and the unfolded portion of the second side panel 220. The existence of the folding indentation line enables the second side panel 220 to be folded along a preset line, thereby facilitating the user to unfold or fold as needed. On the other hand, by reasonably designing the folding indentation line, damage to the second side panel 220 during the folding and unfolding process can be reduced, thereby extending its service life.

[0059] In this embodiment, the first direction X is perpendicular to the second direction Y.

[0060] Further, there are four second side panels 220, two second side panels 220 are arranged at intervals along the first direction X, and two second side panels 220 are arranged at intervals along the second direction Y. Among the two second side panels 220 arranged at intervals in the second direction Y, a portion of one second side panel 220 can be expanded outward, and when the second box body 200 rotates around the first box body 100 to a preset position, the edge of another second side panel 220 abuts against the opposite first side panel 120. This design can be used to help the user determine whether the second box body 200 is rotated to the right position. If it is rotated to the right position, the user can take out the electronic product from the first installation cavity 100a at this time.

[0061] In some embodiments, the connector 300 is inserted into the connecting hole formed by the first slot 120a and the second slot 220a, so that the connector 300 will form a rotating shaft, so that the second box body 200 can rotate around the axis of the connector 300 until the edge of the second side panel 220 abuts against the opposite first side panel 120. In this way, after rotating to a preset position, the second box body 200 can be fixed relative to the first box body 100, without the user having to remove the second box body 200 from the first box body 100, which also facilitates the subsequent repackaging of the electronic product.

[0062] Since at the openings of some packaging boxes, the flaps used to seal the openings need to be fixed with tape, which not only wastes resources but also has a certain impact on the environment. In order to reduce the impact of fixing with tape, in this embodiment, see Figure 5 The second bottom plate 210 includes two first swing covers 211, and the two first swing covers 211 are respectively connected to a group of opposite second side panels 220 along the second direction Y. Specifically, when corrugated paper is used to make the second box body 200, a crease line is also provided between the first swing cover 211 and the second side panel 200, so that the first swing cover 211 can be folded according to a preset line.

[0063] One of the two first swing covers 211 is connected with an inserting tongue 211a, and the other of the two first swing covers 211 is provided with an inserting hole 211b. The inserting tongue 211a is plugged into and matched with the inserting hole 211b to relatively fix the two first swing covers 211.

[0064] The plug-in cooperation between the plug tongue 211a and the plug hole 211b can provide a relatively stable connection, so that the two first swing covers 211 can maintain a certain stability in the closed state and are not easily separated by external force.

[0065] In this way, by providing the inserting tongue 211a or the inserting hole 211b on the first swing cover 211, rapid closing can be achieved without causing waste of resources and environmental pollution.

[0066] Please continue reading Figure 5 , an insertion tongue indentation line is provided between the insertion tongue 211a and the first swing cover 211. The design of the insertion tongue indentation line enables the insertion tongue 211a to be easily folded out from the main body of the first swing cover 211 to form an independent structure that can be inserted into the insertion hole 211b. This design not only enhances the connection strength between the insertion tongue 211a and the first swing cover 211, but also improves the accuracy and efficiency of the plugging operation.

[0067] In addition, the indentation line of the insert tongue also helps to maintain the shape stability of the insert tongue 211a. During the folding and insertion process, the indentation line of the insert tongue can ensure that the insert tongue 211a remains flat and straight, so that it is easier to insert into the insertion hole 211b.

[0068] Furthermore, the inserting tongue 211a includes a plurality of inserting tongues 211a, which are arranged at intervals along the edge of the first swing cover 211. The dispersed layout of the plurality of inserting tongues 211a can more effectively disperse the external force, so that the first swing cover 211 is not easily deformed or loosened when subjected to external force. When the first swing cover 211 needs to completely close the opening of the carton, the plurality of inserting tongues 211a can ensure that the first swing cover 211 and the second side plate 220 are in closer contact, reduce gaps, and improve the overall sealing performance.

[0069] Further, see Figure 5 In some embodiments, the second bottom plate 210 includes two second swing covers 212, and the two second swing covers 212 are respectively connected to a group of opposite second side plates 220 along a first direction X, and the second direction X is perpendicular to the first direction Y.

[0070] The second flap 212 serves as an inner flap, and the first flap 211 serves as an outer flap. The inner flap can first cover the electronic products in the second accommodating cavity 200a, while the outer flap further enhances the sealing and structural stability of the second carton 200, preventing external factors such as moisture and dust from invading the second accommodating cavity 200a, thereby ensuring the safety and cleanliness of the electronic products during storage and transportation.

[0071] The distribution direction of the two second flaps 212 is perpendicular to the distribution direction of the two first flaps 211, so that the overall structure of the second carton 200 is strengthened. This design can effectively prevent the entire second carton 200 from being deformed or damaged due to external forces during transportation or storage.

[0072] As one of the ways to remove electronic products, specifically:

[0073] Moving the second box 200 from the first position to the second position;

[0074] Insert the connecting member 300 into the second slot 220a at the lower end of the second side plate 220 and the first slot 120a at the upper end of the first side plate 120;

[0075] Open the folding portion 221, and flip the second box body 200 around the connecting member 300, until the second side plate 220 opposite to the second side plate 220 where the folding portion 221 is located abuts against the corresponding first side plate 120;

[0076] The electronic product is taken out from the first installation cavity 100 a of the first box 100 .
