[0002] This application claims priority to Chinese patent application No. 202520525130.0, filed on March 24, 2025, entitled “Foam Box”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of express delivery and logistics, and in particular to a foam box. Background Technology

[0004] Currently, the express delivery industry commonly uses foam boxes for packaging to insulate or protect items. After the lid and body of the box are closed, tape is often used to seal the box. Because the seam between the box and the lid is not obvious, it is difficult for the recipient to find the gap and accurately cut the tape when opening the box. If the tape is cut onto the foam box, it will affect the lifespan of the foam box.

[0005] In related technologies, adhesive-cutting grooves are provided on the side walls of the box and the side walls of the lid, so that fingers can be inserted into the adhesive-cutting grooves and pulled up to cut the tape. However, the adhesive-cutting grooves on the box or lid are often groove structures. When the opening of the groove is covered by tape, it is inconvenient for the person opening the box to insert their fingers into the adhesive-cutting groove due to the obstruction of the tape. Summary of the Invention

[0006] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a foam box in which the fingers of the person opening the box can be inserted through a second opening into a first tape-cutting groove and pulled outward to easily cut the tape.

[0007] The foam box according to a first aspect embodiment of this application includes:

[0008] A housing, the housing defining a receiving cavity for receiving articles;

[0009] A lid that closes to the box body to seal the accommodating cavity;

[0010] The side wall of the box cover defines a first glue-breaking groove, and the first glue-breaking groove forms a first opening on the side wall of the box cover. The first glue-breaking groove is configured to extend along the thickness direction of the box cover and penetrate to the top wall of the box cover to form a second opening on the top wall of the box cover.

[0011] The foam box according to the embodiments of this application has at least the following beneficial effects:

[0012] The operator can insert their fingers through the second opening into the first tape-cutting groove and move them outwards towards the first opening until they come into contact with the tape. Pulling the tape outwards then removes the tape covering the first opening, making it easier to cut. After the tape is cut at the first tape-cutting groove, the operator can use the cut point as a starting point to tear off the tape wrapped around the perimeter of the foam box, allowing the lid to be separated from the box body without needing to cut the tape around the seam, thus avoiding damage to the foam box with a knife. Furthermore, the upward-through design of the first tape-cutting groove allows the operator to cut the tape easily and reliably from the groove, unaffected by the tape's adhesive position.

[0013] According to some embodiments of this application, either the lid or the body of the box is provided with a slot along its circumference, and the other is provided with a protrusion along its circumference. When the lid is closed on the body of the box, the protrusion is inserted into the slot.

[0020] According to some embodiments of this application, the second adhesive break groove also has a third sidewall and a fourth sidewall adjacent to the second bottom wall, the third sidewall and the fourth sidewall being disposed opposite to each other;

[0021] The third sidewall and the fourth sidewall each have a locking groove, and the two ends of the rigid component are respectively inserted into the locking groove of the third sidewall and the locking groove of the fourth sidewall.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] Currently, the express delivery industry commonly uses foam boxes for packaging to insulate or protect items. After the lid and body of the box are closed, tape is often used to seal the box. Because the seam between the box and the lid is not obvious, it is difficult for the recipient to find the gap and accurately cut the tape when opening the box. If the tape is cut onto the foam box, it will affect the lifespan of the foam box.

[0044] In related technologies, adhesive-cutting grooves are provided on the side walls of the box and the side walls of the lid, so that fingers can be inserted into the adhesive-cutting grooves and pulled up to cut the tape. However, the adhesive-cutting grooves on the box or lid are often groove structures. When the opening of the groove is covered by tape, it is inconvenient for the person opening the box to insert their fingers into the adhesive-cutting groove due to the obstruction of the tape.

[0045] To address the aforementioned problems to some extent, this application proposes a foam box comprising a box body 200 and a lid 100. It should be noted that the foam box of this application can be made of EPS (polystyrene) material, which is relatively inexpensive. In some examples, the foam box of this application can also be made of EPP (expanded polypropylene) material. EPP foam boxes have high strength and toughness, can withstand certain external impacts without easily being damaged, can be reused multiple times, have a long service life, and are suitable for long-term use and frequent transportation. Furthermore, EPP foam boxes have excellent thermal insulation performance. Due to their unique closed-cell structure, they can effectively prevent heat conduction, convection, and radiation, thus maintaining a stable internal temperature for a long time.

[0046] As shown in Figures 1 and 5, the box body 200 defines a receiving cavity for storing items and a top opening communicating with the receiving cavity. Operators can remove items from the receiving cavity through the top opening or place items into the receiving cavity through the top opening. The box lid 100 can be connected to the box body 200 and closes to the top opening of the box body 200, so that the receiving cavity is in a relatively closed state, thus providing good thermal insulation and protective performance.

[0047] As shown in Figures 2 and 3, the side wall of the box lid 100 defines a first adhesive-breaking groove 110. The first adhesive-breaking groove 110 forms a first opening 111 on the side wall of the box lid 100. Furthermore, the first adhesive-breaking groove 110 extends upward along the thickness direction of the box lid 100 until it penetrates to the top wall of the box lid 100, forming a second opening 112 on the top wall of the box lid 100. It is understood that when the sealing tape is wrapped along the side wall of the box lid 100, it must be ensured that at least a portion of the tape is located on the first adhesive-breaking groove 110.

[0048] Because the first adhesive-cutting groove 110 of this application extends upward to the top wall of the box lid 100, whether the tape covers part or all of the first opening 111, it will not affect the opening action of the person opening the box. The person opening the box can insert their fingers into the first adhesive-cutting groove 110 through the second opening 112 and move them outward along the direction close to the first opening 111 until they come into contact with the tape, and then pull the tape outward to remove the tape covering the first opening 111, thus facilitating the cutting of the tape. Alternatively, the person opening the box can also use a stick, bar, or other tool to insert into the first adhesive-cutting groove 110 through the second opening 112 and pull the tape to cut it. Alternatively, the person opening the box can also use a blade or the like to insert into the first adhesive-cutting groove 110 through the second opening 112 and cut the tape.

[0049] After the tape is cut at the first tape-cutting groove 110, the person opening the box can use the cut tape as a starting point to tear off the tape wrapped around the foam box, and then separate the box lid 100 from the box body 200 without having to cut the tape around the seam 300, thus avoiding scratching the foam box with a knife. In addition, due to the upward through-groove design of the first tape-cutting groove 110, the person opening the box can cut the tape more easily and steadily from the first tape-cutting groove 110, without being affected by the adhesive position of the tape.

[0050] In some embodiments, as shown in Figures 2, 5, and 6, the lid 100 is provided with an insertion groove 140, which is arranged circumferentially around the lid 100 and located near the edge. As shown in Figures 5, 6, and 7, the box body 200 is provided with an insertion protrusion 220, which is arranged circumferentially around the box body 200. When the lid 100 is closed on the box body 200, the insertion protrusion 220 is inserted into the insertion groove 140. It can be understood that the cooperation between the insertion protrusion 220 and the insertion groove 140 helps to initially restrict the movement of the lid 100 and the box body 200 on the horizontal plane, thereby facilitating the sealing personnel to wrap tape to fix the lid 100 and the box body 200. On the other hand, the cooperation between the lid 100 and the box body 200 through the protrusion and groove enhances the sealing and waterproof performance of the foam box.

[0051] It is understood that in other embodiments, the cover 100 may also have a plug-in protrusion 220 and a plug-in groove 140.

[0052] In an exemplary 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, as shown in Figures 3, 5, and 6. The first bottom wall 113 is the groove wall opposite to the first opening 111, and the first bottom wall 113 protrudes from the first opening 111 along the direction directly opposite to the first opening 111. As shown in Figure 6, along the direction close to the body 200, the distance from the first bottom wall 113 to the side wall of the lid 100 gradually decreases, that is, along the direction from top to bottom, the groove depth of the first glue-breaking groove 110 gradually decreases.

[0053] Taking the embodiment shown in Figure 6 as an example, 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 arranged circumferentially along the main body. As shown in the bottom view in Figure 2, the first protrusion 120 and the second protrusion 130 are arranged in a ring structure with intervals. 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. As shown in Figure 6, the first glue-breaking groove 110 is disposed through the box cover 100 along the thickness direction of the box cover 100. Thus, the first glue-breaking groove 110 is partially located on the main body and at least partially located on the first protrusion 120. If the first glue-breaking groove 110 has a uniform depth structure, the thickness of the first protrusion 120 will be thinner after the first glue-breaking groove 110 is opened, and its structural strength will be greatly affected, making it prone to breakage. In this embodiment, the first glue-breaking groove 110 is set in an inclined shape. The closer it is to the bottom of the box cover 100, the smaller the groove depth of the first glue-breaking groove 110, thereby reducing the impact on the structural strength of the first protrusion 120.

[0054] In other embodiments, the insertion groove 140 is directly formed on the main body of the cover 100, so that part of the first glue-breaking groove 110 is located between the groove wall of the insertion groove 140 and the side wall of the cover 100. The inclined design of the first glue-breaking groove 110 can reduce the impact on the structural strength of the cover 100.

[0055] In some embodiments, as shown in FIG4, the first adhesive-breaking groove 110 has a first sidewall 114 and a second sidewall 115 adjacent to the first bottom wall 113, and the first sidewall 114 and the second sidewall 115 are disposed opposite to each other. Along the direction from the first sidewall 114 to the second sidewall 115, the distance from the first bottom wall 113 to the sidewall of the lid 100 gradually increases and then gradually decreases. The first bottom wall 113 can be a conical structure formed by the intersection of two inclined surfaces, or it can be an arc surface (refer to FIG4). The middle groove of the first adhesive-breaking groove 110 is deeper and the side grooves are shallower, thereby reducing the amount of material removed from the lid 100 and thus reducing the impact on the structural strength of the lid 100.

[0056] In some embodiments, as shown in Figures 5, 6, and 7, after the box body 200 and the box lid 100 are closed, a seam 300 is defined between the box body 200 and the box lid 100. The side wall of the box body 200 defines a second adhesive-cutting groove 210, which extends toward the box lid 100 to connect to the seam 300. Thus, in cases where the tape is applied too low, making it inconvenient to pull the tape up from the first adhesive-cutting groove 110, the person opening the box can also cut the tape from the second adhesive-cutting groove 210.

[0057] In one example, the first tape-cutting groove 110 extends toward the box body 200 to the connecting seam 300, and the first tape-cutting groove 110 and the second tape-cutting groove 210 are connected. Thus, an operator can insert their fingers (or other tools) through the second opening 112 into the first tape-cutting groove 110 and the second tape-cutting groove 210 to pull up and cut the entire tape.

[0058] In one example, as shown in Figures 6 and 8, 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 prevent 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 or puncture the tape in the first direction as shown in Figure 8, the rigid component 230 can protect the foam box and prevent damage to the box body 200 when the person opening the box uses excessive force.

[0059] In one example, 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, with the third side wall 213 and the fourth side wall 214 arranged opposite to each other. As shown in Figure 8, both the third side wall 213 and the fourth side wall 214 are provided with locking grooves. One side wall of the locking groove is flush with the second bottom wall 212 of the second adhesive-breaking 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 side wall 213 and the fourth side wall 214 respectively, thereby fixing the rigid component 230 in the second adhesive-breaking groove 210.

[0060] During the installation of the rigid component 230, it is inserted from top to bottom into the second adhesive break groove 210. Since the first adhesive break groove 110 and the second adhesive break groove 210 are connected, to prevent the rigid component 230 from sliding from the second adhesive break groove 210 to the first adhesive break 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 break groove 110 and the seam 300 must be less than the groove depth at the connection between the second adhesive break groove 210 and the seam 300. That is, the groove depth at the lower end of the first adhesive break groove 110 is less than the groove depth at the upper end of the second adhesive break groove 210. Thus, as shown in Figure 6, when the box cover 100 is closed on the box body 200, the box cover 100 blocks the upward movement path of the rigid component 230. In other embodiments, the box cover 100 directly abuts against the top of the rigid component 230, thereby confining the rigid component 230 within the second adhesive break groove 210.

[0061] 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.

[0062] 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. The first edge 150 can be a rounded corner structure as shown in Figure 6, or it can be an arc-shaped structure as shown in Figure 9, or a beveled structure as shown in Figure 8.

[0063] 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.

[0064] In addition, in the top view of the box cover 100 shown in Figure 2, 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.

[0065] 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.

[0066] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
