Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically a multifunctional foldable food delivery box. Background Technology

[0002] With the booming development of the internet economy and the accelerated pace of life, industries such as food delivery, fresh food cold chain, and central kitchen food transportation continue to expand. As key equipment in these industries to ensure the safety, hygiene, warmth, and integrity of food during transportation, food delivery boxes are facing increasing market demand, and the requirements for their functionality, convenience, and intelligence are becoming increasingly stringent. Traditional food delivery boxes mostly adopt a rigid, fixed box structure, consisting of a bottom plate, side panels, and a lid. While this structure is sturdy and durable, it has a significant drawback: the volume of the box when empty is the same as when fully loaded, resulting in a huge space requirement for warehousing and return transport. For delivery merchants, the stacking of a large number of empty boxes incurs expensive warehousing costs; for delivery personnel, the inefficient use of vehicle space limits the number of orders that can be delivered per trip, reducing operational efficiency.

[0003] Currently, some foldable food delivery boxes have appeared on the market, which reduce the volume when not in use to some extent. However, the above-mentioned foldable boxes still have the following problems in actual use: the folding structure and stability are contradictory. In order to pursue foldability, many foldable boxes sacrifice the structural rigidity and stability of the box after unfolding. The connection between the side panel and the bottom panel is often loose. When subjected to bumps or compression during transportation, it is easy to shake or even fold accidentally, which poses a risk of food spillage. The shape is loose after folding. After folding, some boxes lack effective binding and fixing between the various parts (side panels, lid), forming a loose "package". It is easy to fall apart when handling and stacking, which increases the management difficulty and does not truly achieve the original intention of "convenience". Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional foldable food delivery box that has the advantages of efficient space utilization and orderly folding.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multifunctional foldable food delivery box, including a base plate, with baffles fixedly provided on both sides of the top of the base plate, and a second side plate provided on the top of the baffles, with the bottom edge of the second side plate connected to the top edge of the baffles via a connecting hinge, a first side plate slidably rotatably provided on both the front and back of the base plate, the first side plate being connected to the adjacent second side plate via a locking component, and locking their positions after the first and second side plates are unfolded, so that a large cavity for placing food is formed between the first and second side plates and the base plate, a restraining component is provided on the side of the base plate, and a box lid is snapped onto the top of the base plate.

[0006] A further feature of this invention is that the inner side of the stop is provided with a sliding groove, and the bottom of the first side plate is provided with a slider via a connecting shaft, the slider being slidably connected to the sliding groove.

[0007] A further feature of this invention is that the locking component includes a positioning groove and a positioning seat. The positioning groove is disposed on both sides of the first side plate, and the positioning seat is disposed on the inner side of the second side plate. When the first side plate and the second side plate are unfolded to a vertical state, the positioning seat engages with the positioning groove.

[0008] A further feature of this invention is that: a guide hole communicating with a positioning groove is provided on the outer side of the first side plate, a positioning rod is slidably provided inside the guide hole, a connecting seat is fixedly provided at the outer ends of the two positioning rods located on one side, and a positioning spring sleeved on the outside of the positioning rod is installed between the connecting seat and the first side plate, and a positioning hole corresponding to the positioning rod is provided on one side of the positioning seat.

[0009] A further feature of this invention is that the upper surface of the base plate is provided with multiple slots, and a partition is engaged inside the slots to divide the interior into multiple small cavities for placing food.

[0010] A further feature of this invention is that: a sealing seat is fixedly provided at the bottom of the box cover and engages with the top of the large cavity; the sealing seat is made of rubber; a handle is provided in the middle of the box cover; a guide groove is provided on the surface of the box cover to slide with the handle; folded edges are provided at the bottom of both sides of the handle to limit movement; and finger grooves are provided on the surface of the handle.

[0011] A further feature of this invention is that the restraint component includes a connecting ring and an elastic restraint band. The connecting ring is fixedly disposed on both sides of the base plate, and hooks are fixedly disposed at both ends of the elastic restraint band. After the first side plate and the second side plate are folded, the hooks at both ends of the elastic restraint band are connected to the connecting rings on both sides respectively.

[0012] A further feature of this invention is that the interior of the first side plate and the second side plate is hollow and filled with thermal insulation cotton.

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. It achieves high efficiency in space utilization. The folding process is orderly and regular. Through a unique combination of sliding rotation and hinge structure, the folding of the side panels is not chaotic, but follows a clear sequence. First, the two side panels are folded into the two stops of the bottom plate. Then, the two side panels are folded down and covered on the side panels. This sequential stacking folding method makes all the components compactly gathered in the projected area of ​​the bottom plate, forming a regular flat whole. This greatly reduces the space occupied during idle and return transportation, and significantly improves storage and vehicle efficiency.

[0015] 2. The rigidity and stability of the unfolded container are guaranteed, and operation is convenient and reliable. When unfolded, the container's stability is no different from a fixed container. Through locking components on side panels one and two, specifically the design where the positioning rod automatically engages with the positioning hole under spring action, each side panel can be quickly and effectively locked in the vertical working position. This locking mechanism is simple to operate; simply pull the connecting seat outward to unlock, and it will automatically lock under spring return action, ensuring that the container will not accidentally loosen due to bumps during transportation, greatly guaranteeing the safety of the food inside during transport.

[0016] 3. Significantly improved sealing performance and heat preservation effect of the box. While focusing on folding function, the core requirement of heat preservation and delivery is not sacrificed at all. First, rubber sealing lips are set at the joints of all adjacent side panels to effectively prevent hot and cold air from leaking out of the gaps. Second, the rubber sealing seat at the bottom of the lid fits tightly with the top of the box to form a second line of defense. More importantly, the inside of the side panels is hollow and filled with heat insulation cotton to form a highly efficient heat insulation layer. These three measures work together to enable the box to maintain the internal temperature for a long time after unfolding, meeting the strict requirements of cold chain or hot food delivery.

[0017] 4. The internal space layout has been optimized to enable food to be stored in categories. Multiple slots on the bottom plate allow users to flexibly insert partitions according to the specific types and quantities of food delivered each time, freely dividing the large cavity into multiple independent sub-chambers. This design effectively avoids the problem of different foods (such as cold drinks and hot meals, fruits and soups) mixing flavors, being squeezed or cross-contaminated during transportation, thus improving the professionalism of the delivery service and the quality of the food.

[0018] 5. The handle on the lid is cleverly designed. Its sliding and retractable feature prevents bumps when stacking or storing the cases. Simply pull it up when in use, which is very effortless. The finger grooves on the handle surface further enhance the comfort of gripping. The folding restraint components, namely the elastic restraint strap and hook, can easily and tightly restrain the entire folded case, making the folded case a whole unit that is easy to move and stack, and very convenient to manage.

[0027] The present invention will be further described below with reference to the accompanying drawings of the embodiments thereof.

[0028] Please see Figures 1-7In this embodiment of the utility model, a multifunctional foldable food delivery box includes a base plate 1. An anti-slip pad is fixedly provided at the bottom end of the base plate 1 for anti-slip purposes. Both sides of the top of the base plate 1 are fixedly provided with stop seats 101. The top of the stop seats 101 is provided with a second side plate 3. The bottom edge of the second side plate 3 is connected to the top edge of the stop seat 101 via a connecting hinge 301. The bottom of the second side plate 3 and the top of the stop seat 101 are provided with grooves for installing the connecting hinge 301, allowing the second side plate 3 to be folded and unfolded. The front and back of the base plate 1 are slidably provided with a first side plate 2. The first side plate 2 is connected to the adjacent second side plate 3 via a locking component. After the first side plate 2 and the second side plate 3 are unfolded, their positions are locked, forming a large cavity for placing food between the first side plate 2, the second side plate 3, and the base plate 1. The upper surface of the base plate 1 is provided with multiple slots 103. The interior is fitted with a partition 4, dividing the interior into multiple small cavities for food storage, allowing for the categorization and placement of different foods. The side panels 2 and 3 are hollow and filled with insulating cotton for heat insulation. Adjacent side panels 2 and 3 have rubber sealing lips to seal the joints. The side panels 2 and 3 can be folded and unfolded. When folding the box, first fold side panel 2 between the two blocks 101, then fold side panel 3 above side panel 2, stacking them sequentially to reduce space usage. The bottom plate 1 has restraining components on its side to secure the folded side panels 2 and 3. A lid 5 is fitted on the top of the bottom plate 1 to protect the food inside. A raised strip is located on the top of the outer side of side panel 3 for handling the unfolded box.

[0029] In this embodiment, preferably, the inner side of the stop 101 is provided with a sliding groove 102, and the bottom of the side plate 2 is provided with a slider 202 through the connecting shaft 201. The slider 202 is slidably connected to the sliding groove 102. The sliding cooperation between the slider 202 and the sliding groove 102 guides the movement of the side plate 2. When the side plate 2 needs to be folded, the side plate 2 is first pulled upward and then the side plate 2 is folded inward by the rotational cooperation between the connecting shaft 201 and the slider 202. Then, under the action of gravity, the side plate 2 can be placed horizontally on the base plate 1.

[0030] In this embodiment, preferably, the locking component includes a positioning groove 203 and a positioning seat 302. The positioning groove 203 is disposed on both sides of the first side plate 2, and the positioning seat 302 is disposed on the inner side of the second side plate 3. When the first side plate 2 and the second side plate 3 are unfolded to a vertical state, the positioning seat 302 engages with the positioning groove 203, thereby limiting the position of the unfolded first side plate 2 and the second side plate 3 by the engagement between the positioning seat 302 and the positioning groove 203. The outer side of the first side plate 2 is provided with a guide hole 204 communicating with the positioning groove 203. A positioning rod 205 is slidably disposed inside the guide hole 204, and the outer ends of the two positioning rods 205 located on one side are fixedly connected. The connecting seat 206 and the side plate 2 are fitted with a positioning spring 207 that is sleeved on the outside of the positioning rod 205. The positioning seat 302 has a positioning hole 303 on one side corresponding to the positioning rod 205. When the box is changed from unfolded to folded, the connecting seat 206 is pulled outward to separate the positioning rod 205 on one side of the connecting seat 206 from the positioning hole 303, thereby releasing the lock on the position of the side plate 2 and the side plate 3. Then the side plate 2 and the side plate 3 are folded. In the unfolded state, the positioning rod 205 can be engaged in the positioning hole 303 under the elastic action of the positioning spring 207, thereby locking the position of the side plate 2 and the side plate 3.

[0031] In this embodiment, preferably, the bottom end of the lid 5 is fixedly provided with a sealing seat 501 that engages with the top of the large cavity. The sealing seat 501 is made of rubber and can play a sealing role after the lid 5 is installed, and limit the position of the lid 5. The middle part of the lid 5 is provided with a handle 503. The surface of the lid 5 is provided with a guide groove 502 that slides with the handle 503, so that the handle 503 moves to the bottom under the action of gravity when not in use, reducing the space occupied. The bottom of both sides of the handle 503 is provided with folded edges 504 that play a limiting role, which can limit the position of the handle 503 and prevent the handle 503 from falling off the lid 5. The surface of the handle 503 is provided with finger grooves to facilitate the lifting of the handle 503. A sealing ring is embedded on the lower surface of the lid 5, which increases the sealing between the lid 5 and the side plate 2 and the side plate 3 after the lid 5 is installed.

[0032] In this embodiment, preferably, the restraint component includes a connecting ring 6 and an elastic restraint band 601. The connecting ring 6 is fixedly disposed on both sides of the base plate 1, and hooks 602 are fixedly disposed at both ends of the elastic restraint band 601. After the side plate 1 2 and the side plate 2 3 are folded, the hooks 602 at both ends of the elastic restraint band 601 are connected to the connecting rings 6 on both sides respectively, and the position of the folded side plate 1 2 and the side plate 2 3 is limited by the elastic restraint band 601.

[0033] When in use, lay the folded box flat and unfold it. First, flip the side plate 2 3, which is connected to the stop 101 by the connecting hinge 301, upward so that it is perpendicular to the bottom plate 1. Then, hold the side plate 2 and lift it up between the two stops 101. This process is precisely guided because the slider 202 at the bottom of the side plate 2 is slidably connected to the groove 102 inside the stop 101. After side panel 2 is lifted to the top, it is rotated to fit against the inner wall of the already erected side panel 3. During this process, the positioning seat 302 located on the inner side of side panel 3 aligns with the positioning groove 203 on the side of side panel 2. At the same time, inside side panel 2, the positioning rod 205 located in the guide hole 204 is precisely inserted into the positioning hole 303 on the positioning seat 302 under the return force of the positioning spring 207, which automatically completes the rigid interlock between side panel 2 and side panel 3, forming a stable rectangular box frame. Finally, the box cover 5 is pressed down, so that the rubber sealing seat 501 at its bottom end is tightly engaged with the box opening formed by the top of side panel 2 and side panel 3. The elastic deformation of the rubber achieves the seal. At this time, a complete and sealed large cavity is formed inside the box, which can be used to place food.

[0034] When delivery is complete and the box is empty, it needs to be folded to save space. First, pull the connecting seats 206 on both sides of side panel 2 outwards simultaneously. The connecting seats 206 drive the two positioning rods 205 to overcome the elastic force of the positioning springs 207 and retract into the guide holes 204, so that their ends completely exit from the positioning holes 303 of the positioning seats 302, thereby releasing the lock between side panel 2 and side panel 3. After releasing the lock, first lift side panel 2 slightly outwards and upwards, and then rotate it inwards with its bottom connecting shaft 201 as the axis, so that it lies flat on the bottom plate 1. Located between two stop seats 101; then, with the connecting hinge 301 as the axis, the second side panel 3 will be flipped down so that it covers the already flattened first side panel 2; after all the side panels are folded, the hooks 602 at both ends of the elastic binding strap 601 are hooked onto the connecting rings 6 on both sides of the bottom plate 1 respectively. Using the elastic contraction force of the elastic binding strap 601, the stacked first side panel 2 and second side panel 3 are tightly bound to the bottom plate 1, and the partition 4 and the box cover 5 are placed flat on top of it in sequence to form a compact whole, preventing it from falling apart and making it easy to transport and stack for storage;

[0035] After the box is unfolded, the lower edge of the partition 4 can be inserted into different slots 103 on the bottom plate 1 according to delivery needs, thereby flexibly dividing the large cavity into multiple independent small chambers to achieve classified storage of food and avoid cross-contamination of odors and compression. During the entire transportation process, the insulation cotton filled in the internal cavity of side plate 1 2 and side plate 2 3 continuously plays a heat insulation role, effectively slowing down the exchange of heat between the inside and outside of the box. Combined with the sealing seat 501 at the box opening and the sealing lip at the side plate joint, the sealing system formed together ensures that the temperature inside the box is stable for a long time, meeting the requirements of heat preservation or cold preservation for delivery. After folding and securing, you can hold the finger groove on the surface of the handle 503 and pull it upwards. The handle 503 can slide along the guide groove 502 for carrying. When the box is lowered, the handle 503 automatically slides down to the lower position under the action of gravity.

[0036] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
