[0043] In the description of the utility model, the description of reference terms "one embodiment", "some embodiments", "illustrative embodiment", "example", "specific example" or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the utility model.In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example.Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0044] At present, the express industry generally uses foam boxes for packaging in order to keep the goods warm or protect them.When the box cover is closed with the box body, adhesive tape is often used to seal the box, and since the joint between the box body and the box cover is not obvious, it is difficult for the receiver to find the gap and accurately cut the adhesive tape when opening the box, and if the adhesive tape is cut on the foam box, the service life of the foam box will be affected.

[0045] In the related art, a broken adhesive groove is formed in the side wall of the box body and the side wall of the box cover, so that the fingers can be inserted into the broken adhesive groove and the adhesive tape can be pulled up to facilitate cutting the adhesive tape, but the broken adhesive groove on the box body or the box cover is often a groove structure, and when the opening of the groove is covered by the adhesive tape, it is not convenient for the person opening the box to insert the fingers into the broken adhesive groove.

[0046] To solve the above problems, the application provides a foam box, which comprises a box body 200 and a box cover 100, and it should be noted that the foam box of the application can be made of EPS (polystyrene) material, which has low cost; preferably, it can also be made of EPP (foamed polypropylene) material, and the EPP foam box has high strength and toughness and can withstand certain external impact without being easily damaged, it can be used repeatedly for many times, has long service life and is suitable for long-term use and frequent transportation.In addition, the EPP foam box has excellent heat preservation effect, and due to its unique closed cell structure, it can effectively prevent heat conduction, convection and radiation, so it can maintain stable temperature in the box for a long time.

[0047] As shown in Figure 1 and Figure 5 , the box body 200 defines a receiving cavity for accommodating articles and a top opening in communication with the receiving cavity, through which the operating personnel can take out or put in articles. The box cover 100 can be connected to the box body 200 and covers the top opening of the box body 200, so that the receiving cavity is in a relatively closed state, thereby having good heat preservation and protection performance.

[0048] As shown in Figure 2 and Figure 3 , the side wall of the box cover 100 defines a first glue breaking groove 110, which forms a first opening 111 on the side wall of the box cover 100 and extends upward along the thickness direction of the box cover 100 until it penetrates through the top wall of the box cover 100 and forms a second opening 112 on the top wall of the box cover 100. It can be understood that when the sealing tape is wound along the side wall of the box cover 100, at least part of the tape should be located on the first glue breaking groove 110.

[0049] Since the first glue breaking groove 110 of the present application extends upward to the top wall of the box cover 100, whether the tape covers part of the first opening 111 or covers the entire first opening 111, it will not affect the opening operation of the opening personnel. The fingers of the opening personnel can be inserted into the first glue breaking groove 110 through the second opening 112 and moved outward in the direction close to the first opening 111 until they abut against the tape and pull it outward, so that the tape covering the first opening 111 is pulled up, thereby facilitating the cutting of the tape. Alternatively, the opening personnel can also use a stick, rod or other tool to insert into the first glue breaking groove 110 through the second opening 112 and pull the tape to facilitate the cutting of the tape. Alternatively, the opening personnel can also insert a blade or the like into the first glue breaking groove 110 through the second opening 112 and cut the tape.

[0050] After the tape is cut at the first glue breaking groove 110, the opening personnel can tear off the tape wound around the foam box from the cutting point, and then separate the box cover 100 from the box body 200 without cutting the tape along the joint 300, thereby avoiding the damage of the foam box by the cutting tool. In addition, due to the upward penetration design of the first glue breaking groove 110, the opening personnel can more easily and stably cut the tape at the first glue breaking groove 110, which is not affected by the adhesive position of the tape.

[0051] In some embodiments, as shown in Figure 2 , Figure 5 and Figure 6As shown, the cover 100 is provided with a insertion groove 140, which is arranged circumferentially along the cover 100 and located near the edge. Figure 5 , Figure 6 and Figure 7 As shown, the box body 200 is provided with a plug-in protrusion 220, which is arranged circumferentially around the box body 200. When the box lid 100 is closed on the box body 200, the plug-in protrusion 220 is inserted into the plug-in groove 140. It can be understood that the cooperation between the plug-in protrusion 220 and the plug-in groove 140 serves two purposes: firstly, it helps to initially restrict the movement of the box lid 100 and the box body 200 on the horizontal plane, thus facilitating the sealing personnel to wrap tape around and secure the box lid 100 and the box body 200. Secondly, the cooperation between the protrusion and the groove enhances the sealing and waterproof performance of the foam box.

[0052] It is understood that in other embodiments, the cover 100 may also have a plug-in protrusion 220 and a plug-in groove 140.

[0053] Furthermore, in the embodiment where the lid 100 is provided with an insertion groove 140 and the body 200 is provided with an insertion protrusion 220, the first bottom wall 113 of the first glue-breaking groove 110 is inclined to reduce the impact on the structural strength of the lid 100. Specifically, the first glue-breaking groove 110 has a first bottom wall 113, such as... Figure 3 , Figure 5 and Figure 6 As shown, the first bottom wall 113 is the groove wall opposite to the first opening 111, and along the direction directly opposite to the first opening 111, the first bottom wall 113 protrudes from the first opening 111. Figure 6 As shown, along the direction close to the box body 200, the distance from the first bottom wall 113 to the side wall of the box cover 100 gradually decreases, that is, along the direction from top to bottom, the groove depth of the first glue-breaking groove 110 gradually decreases.

[0054] For example Figure 6 Taking the illustrated embodiment as an example for analysis, the box cover 100 includes a main body and a first protrusion 120 and a second protrusion 130 disposed on the main body. The first protrusion 120 and the second protrusion 130 are disposed circumferentially along the main body, such as... Figure 2 As shown in the bottom view, the first protrusion 120 and the second protrusion 130 are arranged in a spaced-apart ring structure, wherein the first protrusion 120 is located outside the second protrusion 130, and the outer surface of the first protrusion 120 is flush with the side wall of the main body. An insertion groove 140 is defined between the first protrusion 120 and the second protrusion 130. Figure 6As shown, the first glue breaking groove 110 is arranged along the thickness direction of the box cover 100, and thus, the first glue breaking groove 110 is partially arranged on the main body and at least partially arranged on the first protrusion 120. If the first glue breaking groove 110 is of an equal-depth structure, the thickness of the first protrusion 120 will be thinner after the first glue breaking groove 110 is opened, and the structural strength will be greatly affected and the first protrusion 120 will be easily broken. In the embodiment, the first glue breaking groove 110 is arranged in an inclined manner, and the groove depth of the first glue breaking groove 110 is smaller as it is closer to the bottom of the box cover 100, thereby reducing the influence on the structural strength of the box cover 100.

[0055] In some other embodiments (not shown in the drawings), the plug-in groove 140 is directly arranged on the main body of the box cover 100, and thus, part of the first glue breaking groove 110 is arranged between the groove wall of the plug-in groove 140 and the side wall of the box cover 100. The design of the inclined first glue breaking groove 110 can reduce the influence on the structural strength of the box cover 100.

[0056] In some embodiments, as shown in Figure 4 As shown, the first glue breaking groove 110 has a first side wall 114 and a second side wall 115 adjacent to the first bottom wall 113, and the first side wall 114 and the second side wall 115 are oppositely arranged. In the direction from the first side wall 114 to the second side wall 115, the distance from the first bottom wall 113 to the side wall of the box cover 100 first gradually increases and then gradually decreases. The first bottom wall 113 can be a tapered structure formed by the intersection of two inclined surfaces (not shown in the drawings), or can be an arc surface (see Figure 4 As shown, the first glue breaking groove 110 has a first side wall 114 and a second side wall 115 adjacent to the first bottom wall 113, and the first side wall 114 and the second side wall 115 are oppositely arranged. In the direction from the first side wall 114 to the second side wall 115, the distance from the first bottom wall 113 to the side wall of the box cover 100 first gradually increases and then gradually decreases. The first bottom wall 113 can be a tapered structure formed by the intersection of two inclined surfaces (not shown in the drawings), or can be an arc surface (see

[0057] In some embodiments, as shown in Figure 5 、 Figure 6 and Figure 7 As shown, after the box body 200 and the box cover 100 are closed, a joint 300 is defined between the box body 200 and the box cover 100, and the side wall of the box body 200 is provided with a second glue breaking groove 210 extending towards the box cover 100 and communicating with the joint 300. Thus, for the case that the position of the adhesive tape is lower and it is not convenient to pull up the adhesive tape from the first glue breaking groove 110, the unpacking personnel can also cut the adhesive tape from the second glue breaking groove 210.

[0058] Further, the first glue breaking groove 110 extends towards the box body 200 and communicates with the joint 300, and the first glue breaking groove 110 and the second glue breaking groove 210 communicate. Thus, the unpacking personnel can insert a finger (or other tools) into the first glue breaking groove 110 and the second glue breaking groove 210 from the second opening 112 to pull up and cut the entire adhesive tape.

[0059] Furthermore, such as Figure 6 and Figure 8 As shown, the person opening the box can also use a knife to insert into the second tape-cutting groove 210 along the first direction to directly cut the tape covering the second tape-cutting groove 210. To avoid scratching the foam box when cutting the tape, a rigid component 230 is provided in the second tape-cutting groove 210. Specifically, the box body 200 also includes the rigid component 230, the material of which is harder than the material of the box body 200, and is often a plastic sheet, metal sheet, etc. The second tape-cutting groove 210 has a third opening 211 formed on the side wall of the box body 200, and a second bottom wall 212 opposite to the third opening 211, and the rigid component 230 is laid on the second bottom wall 212. Thus, when the person opening the box uses a knife or other sharp tool, to cut the tape, the rigid component 230 can be inserted into the second tape-cutting groove 210. Figure 8 When the tape is torn or punctured by force in the first direction as shown, the rigid component 230 can protect the foam box and prevent damage to the box body 200 when the person opening the box uses too much force.

[0060] Furthermore, the second adhesive-breaking groove 210 also has a third side wall 213 and a fourth side wall 214 adjacent to the second bottom wall 212, the third side wall 213 and the fourth side wall 214 being arranged opposite to each other. Figure 8 As shown, both the third sidewall 213 and the fourth sidewall 214 are provided with locking grooves. One side of the locking groove is flush with the second bottom wall 212 of the second adhesive break groove 210, and the top of the locking groove extends to the top surface of the housing 200. The width of the locking groove is slightly larger than the width of the rigid component 230, so that both ends of the rigid component 230 can be inserted into the locking grooves of the third sidewall 213 and the fourth sidewall 214 respectively, thereby fixing the rigid component 230 in the second adhesive break groove 210.

[0061] During the installation of the rigid component 230, it is inserted from top to bottom into the second adhesive-breaking groove 210. Since the first adhesive-breaking groove 110 and the second adhesive-breaking groove 210 are connected, to prevent the rigid component 230 from sliding from the second adhesive-breaking groove 210 to the first adhesive-breaking groove 110 during transportation and from detaching from the foam box through the second opening 112, the groove depth at the connection between the first adhesive-breaking groove 110 and the seam 300 must be less than the groove depth at the connection between the second adhesive-breaking groove 210 and the seam 300. That is, the groove depth at the lower end of the first adhesive-breaking groove 110 is less than the groove depth at the upper end of the second adhesive-breaking groove 210. Thus, as Figure 6 As shown, when the lid 100 is placed on the box body 200, the lid 100 blocks the upward movement path of the rigid component 230. In other embodiments, the lid 100 directly abuts against the top of the rigid component 230, thereby confining the rigid component 230 in the second adhesive break groove 210.

[0062] Based on the above, the recipient can cut the tape using the first tape-cutting groove 110 and / or the second tape-cutting groove 210, and then separate the tape from the foam box. For some recipients, it is preferable to cut the tape at the circumferential seam 300 to sever the connection between the box lid 100 and the box body 200. Therefore, in some embodiments, the seam 300 of the foam box has been improved to allow the seam 300 to be located quickly and accurately.

[0063] Specifically, the lid 100 has a first edge 150 that connects to both the bottom wall and the side wall of the lid 100. The distance from the first edge 150 to the side wall of the lid 100 gradually decreases in the direction away from the box body 200. It should be noted that the first edge 150 can be formed by chamfering, and the first edge 150 can be as follows: Figure 6 The rounded corner structure shown, or the first edge 150, can also be as follows: Figure 9 The arc-shaped structure shown, such as Figure 8 The oblique structure shown.

[0064] Similarly, the box body 200 also has a second edge 240 that connects to the side wall and top wall of the box body 200 respectively. The first edge 150 and the second edge 240 define the seam 300. Along the direction away from the lid 100, the distance from the second edge 240 to the side wall of the box body 200 gradually decreases. The second edge 240 can be a rounded corner, a bevel, or an arc shape. The structure of the second edge 240 can be the same as or different from that of the first edge 150. For example, the first edge 150 can be a rounded corner structure, while the second edge 240 can be left untreated, forming a right-angle structure where the bottom and side walls meet. Alternatively, both the first edge 150 and the second edge 240 can be rounded corner structures to make the seam 300 more obvious and easier to find, facilitating the cutting of tape by personnel opening the box and reducing the probability of foam box particles falling out or being scratched.

[0065] In addition, in such Figure 2 In the top view of the box cover 100 shown, the top surface of the box cover 100 is provided with multiple partitions, each of which can be set to different functions. For example, one partition can be used to attach express waybills, another partition can be used to attach information codes, and the information codes can be scanned to display the current process information, etc.

[0066] In summary, the foam box of this application allows for easy removal of tape and opening of the box, improving the recipient's unpacking experience. Furthermore, by designing a system to guide recipients or delivery personnel in the correct opening procedure, the lifespan of the foam box can be extended, enabling its recycling and reducing delivery material costs. The convenient opening design of the foam box also reduces the shedding of particles during the opening process, thus minimizing environmental pollution.

Besides, the embodiment and the feature in the embodiment of the utility model can be combined mutually under the condition of not conflicting.
