Description

Technical Field

[0001] This utility model belongs to the field of packaging structure technology, and in particular relates to a hexahedral packaging box. Background Technology

[0002] L-Ascorbyl palmitate is a non-toxic and harmless multifunctional nutritional antioxidant preservative. It possesses antioxidant and nutritional fortification functions, and is used as an antioxidant brightener for Vitamin E, exhibiting a very significant antioxidant effect in oils. It is also heat-resistant, suitable for pharmaceuticals, health products, cosmetics, and as an antioxidant for baking and frying oils, with better antioxidant effects on lard than on vegetable oils. It is commonly used in oily foods, edible oils, animal and vegetable oils, and high-end cosmetics, and can also be used in various infant foods and milk powders. The packaging of L-Ascorbyl Palmitate powder requires high standards during transportation and storage, necessitating tight seals and handling with care to avoid damage.

[0003] Currently, L-ascorbic acid palmitate powder on the market is generally packaged in cylindrical cardboard drums. However, the cylindrical packaging design not only results in low space utilization during transportation and storage, thus increasing logistics and warehousing costs, but also has weak corner support, making it prone to sliding, tilting, and rolling. This increases the risk of instability and damage during stacking, resulting in lower safety during transportation and storage. A rough comparison of the space utilization rates of traditional cylindrical packaging boxes and hexagonal packaging boxes can be made. (See the instruction manual attached.) Figure 5 and 6 As shown, during transportation, the two types of packaging boxes are placed on pallets of the same size and then loaded into trucks of the same size; during warehousing, the two types of packaging boxes are placed in spaces of the same size. It can be seen that the cylindrical packaging box and the hexahedral packaging box occupy the same space. Assuming the radius of the circular outline of the cylindrical packaging box is R, the length and width of the hexahedral packaging box are both 2R. The height of both packaging boxes is H. Therefore, the volume of a single packaging box is V. 六面体 =4HR 2 V 圆柱体 =πHR 2 V 六面体 / V 圆柱体 =4 / π = 1.2732, meaning the hexahedral packaging box has approximately 1.2732 times the space utilization rate of a traditional cylindrical packaging box, or about 27.32% more space. Therefore, the space utilization rate of L-ascorbic acid palmitate powder packaged in the market using traditional cylindrical packaging boxes is lower than that of hexahedral packaging boxes. Furthermore, common packaging boxes on the market also suffer from drawbacks such as the lack of handles or grooves on the outer surface for easy handling, and pressure imbalances between the inside and outside of the box leading to difficulty in opening and closing, deformation, and damage.

[0004] For example, Chinese utility model patent (authorization announcement number: CN203143287U) discloses a cylindrical packaging box, including a box body and a box lid. The box body has a flange, and an inner liner is installed on the top of the box body. The inner liner is in the shape of an inverted boss. The box lid is connected to the box body by threads, with the inner surface of the box lid close to the inner liner and the bottom end of the box lid close to the flange. This utility model has a simple structure and, compared with traditional cylindrical packaging boxes, has the advantages of good protective performance, beautiful appearance, and durability.

[0005] However, the aforementioned cylindrical packaging boxes still suffer from the problems described above: "low space utilization during transportation and storage, leading to increased logistics and warehousing costs; weak support at the edges and corners of cylindrical packaging, making it prone to sliding, tilting, and rolling, thus increasing the risk of damage due to unstable stacking and lower safety during transportation and storage; and the lack of handles or grooves on the outer surface of the packaging box, hindering easy handling, and the imbalance of air pressure inside and outside the box leading to difficulty in opening and closing and deformation damage." Therefore, it is necessary to design a new solution to address these issues. Utility Model Content

[0006] The purpose of this utility model is to provide a hexahedral packaging box, which aims to solve the technical problems in the prior art such as "the structural design of cylindrical packaging boxes leads to low space utilization during transportation and storage, increasing logistics and warehousing costs; the plane corner support of cylindrical packaging boxes is weak, making them easy to slide, tilt and roll off, resulting in low safety during transportation and storage; the design of the packaging box leads to inconvenient handling, difficult opening and closing, and deformation and damage."

[0007] To achieve the above objectives, this utility model provides a hexahedral packaging box. The top surface of the hexahedral packaging box has a limiting protrusion, and the bottom surface has a limiting groove. When the hexahedral packaging boxes are stacked, the limiting groove and the limiting protrusion fit together to prevent relative sliding between the upper and lower packaging boxes in the horizontal direction. The hexahedral packaging box consists of a top cover and a bottom box. A bottom box finger groove is provided at the intersection of the bottom surface of the limiting groove and the side surface of the bottom box. The top cover has a sleeve portion, and the bottom box has an insertion portion. The insertion portion has a corrugated plate, and the corrugated plate is detachably connected to the sleeve portion.

[0008] Optionally, a top cover finger groove is provided at the intersection of the top surface of the limiting protrusion of the top cover and the side surface of the top cover, and when the hexahedral packaging boxes are stacked, the top cover finger groove of the lower hexahedral packaging box is aligned with the bottom box finger groove of the adjacent upper hexahedral packaging box.

[0009] Optionally, the top cover is provided with at least one top cover gripper; the bottom box is provided with at least one bottom box gripper.

[0010] Optionally, the top cover gripper has four grippers; the bottom box gripper has four grippers.

[0011] Optionally, the inner and outer sides of the top cover and the inner and outer sides of the bottom box of the hexahedral packaging box are provided with rounded corners.

[0012] Optionally, the top cover is provided with vent holes on its side.

[0013] The above-mentioned technical solutions of the hexahedral packaging box provided in this utility model embodiment have at least one of the following technical effects: 1. The structural design of the hexahedral packaging box has a higher space utilization rate during transportation and storage than that of the cylindrical packaging box, thereby reducing logistics and warehousing costs; 2. The structural design of the hexahedral packaging box has stronger support force on the plane edges and corners than that of the cylindrical packaging box, and it is also provided with limiting grooves and limiting protrusions, making it less likely for the stacked boxes to slide, tilt and roll off, or even be damaged, thus improving the safety of transportation and storage; 3. The design of the finger grooves, grippers and ventilation holes makes it more time-saving, labor-saving, efficient and convenient to handle and open and close the packaging box.

Detailed Implementation

[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0024] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, such as Figures 1-6As shown, the hexahedral packaging box can be either a cube or a cuboid. The top surface of the hexahedral packaging box 10 has a limiting protrusion 110, and the bottom surface has a limiting groove 210. When the hexahedral packaging boxes 10 are stacked, the limiting groove 210 and the limiting protrusion 110 fit together to prevent relative sliding between the upper and lower packaging boxes in the horizontal direction. The hexahedral packaging box 10 consists of a top cover 100 and a bottom box 200. A bottom box finger groove 220 is provided at the intersection of the bottom surface of the limiting groove 210 and the side surface of the bottom box 200. The top cover 100 has a sleeve portion 140, and the bottom box 200 has an insertion portion 240. The insertion portion 240 has a corrugated plate 241, which is detachably connected to the sleeve portion 140. The corrugated plate 241 has good cushioning performance, absorbing external impact and protecting the items inside the packaging box. During stacking and transportation, the joints are susceptible to pressure. The design of the corrugated board 241 enhances its pressure resistance, preventing the packaging box from deforming or even being damaged. The corrugated structure of the corrugated board 241 also effectively disperses external forces, making the joints stronger and less prone to deformation or breakage. During the opening and closing of the packaging box, the joints bear significant stress and are the most susceptible to wear. The toughness of the corrugated board 241 reduces wear and fatigue damage, significantly improving its durability and extending the lifespan of the packaging box. The elasticity of the corrugated board 241 also allows for a more flexible connection between the top cover 100 and the bottom box 200, resulting in smoother opening and closing and enhancing user comfort. Furthermore, the texture of the corrugated board 241 adds a design element to the joints, allowing them to blend seamlessly with other parts and enhancing the overall aesthetics.

[0028] Specifically, during transportation, when placed on pallets 400 of the same size and loaded into a carriage 500 with the same space, the hexahedral packaging box 10 has a higher space utilization rate than the cylindrical packaging box. During storage, occupying the same space, the hexahedral packaging box 10 has a higher space utilization rate than the cylindrical packaging box. Therefore, the structural design of the hexahedral packaging box 10 reduces logistics and warehousing costs compared to the cylindrical packaging box. The hexahedral packaging box 10 has stronger support at the planar edges and corners than the cylindrical packaging box, and also features limiting grooves 210 and limiting protrusions 110, making it less likely for stacked packaging boxes to slip, tilt, roll off, or even be damaged, thus enhancing transportation and storage safety.

[0029] In another embodiment of this utility model, such as Figures 1-4As shown, a top cover finger groove 120 is provided at the intersection of the top surface of the limiting protrusion 110 of the top cover 100 and the side surface of the top cover 100. When the hexahedral packaging boxes 10 are stacked, the top cover finger groove 120 of the lower hexahedral packaging box 10 is aligned with the bottom box finger groove 220 of the adjacent upper hexahedral packaging box 10, leaving space for fingers or robotic arms to exert force to move the hexahedral packaging boxes 10. The top cover finger groove 120 and the bottom box finger groove 220 are aligned at least once; in this embodiment, they are aligned at four times, which facilitates multi-angle and multi-directional force exertion by fingers or robotic arms, and avoids the top cover finger groove 120 and the bottom box finger groove 220 being blocked after the hexahedral packaging boxes 10 are tightly stacked, causing inconvenience. During the loading, unloading and handling of the hexahedral packaging boxes 10, the space left by the top cover finger groove 120 and the bottom box finger groove 220 directly supports the bottom of the hexahedral packaging box 10, which has a good force distribution effect and is convenient and efficient. A slot is made on both the top cover 100 and the bottom box 200 so that the wall thickness of the top and bottom surfaces of the hexahedral packaging box 10 is not significantly increased while ensuring the strength and stability of the hexahedral packaging box 10.

[0030] In another embodiment of this utility model, such as Figure 1 As shown, the top cover 10 is equipped with at least one top cover gripper 130, which allows for the application of vertical force to open the cover by gripping the top cover gripper 130. This avoids the traditional methods of prying open the top cover 100 by connecting it to the periphery of the bottom box 200 or pulling it upwards by applying friction to the vertical side of the top cover 100, thus preventing compression or even damage to the top cover 100 and providing a faster and more efficient opening. During the opening process, gripping the top cover gripper 130 also allows for quicker alignment and prevents compression of the top cover 100. The bottom box 200 is equipped with at least one bottom box gripper 230, allowing for direct gripping of the waist of the hexahedral packaging box 10 during loading, unloading, and handling to move the hexahedral packaging box 10. This prevents damage caused by compression of the sides of the bottom box 200 or slippage of the hexahedral packaging box 10, and also makes it more convenient and comfortable to use. Four top cover grippers 130 are provided, facilitating opening and closing of the top cover 100 from multiple angles and directions, improving ease of use and work efficiency. The base box has four grippers 230, which allows for gripping from multiple angles and directions, improving ease of use and work efficiency.

[0031] In another embodiment of this utility model, such as Figures 1-3As shown, the inner and outer sides of the top cover 100 and the inner and outer sides of the bottom box 200 of the hexahedral packaging box 10 are all provided with rounded corners 300. The rounded corners 300 design reduces stress concentration, avoids deformation or tearing caused by collisions during movement and handling, and improves the stability and durability of the overall structure. The rounded corners 300 design can reduce wear caused by friction with other objects during transportation, stacking, or handling, extending its service life. Moreover, during use, opening, closing, and handling, the hexahedral packaging box 10 will enter the user's or staff's field of vision, and may even require manual opening, closing, and handling. At this time, the rounded corners 300 design can avoid sharp right angles causing scratches to the user, is more ergonomic, and the rounded arcs can also avoid aggression and be more approachable, thereby improving sensory comfort.

[0032] In another embodiment of this utility model, such as Figures 1-2 As shown, the top cover 100 has ventilation holes 150 on its side. Ventilation holes 150 ensure pressure balance inside and outside the box, allowing air to circulate freely. This prevents excessive pressure buildup inside the box or negative pressure compressing the box, which could cause deformation or damage, thus protecting the packaging and contents. Ventilation holes 150 also facilitate smoother opening and closing of the box, enhancing user comfort. Specifically, when closing the box, ventilation holes 150 allow air to escape smoothly, reducing resistance and making the top cover 100 easier to close; when opening the box, ventilation holes 150 prevent the top cover 100 from being difficult to open due to negative pressure. Promoting air circulation also prevents moisture buildup inside the box, reducing the risk of the contents becoming damp; simultaneously, it prevents odor retention, reducing odor buildup and keeping the air inside the box fresh. The vent 150 allows the hexahedral packaging box 10 to adapt to temperature changes, preventing expansion or contraction. In environments with large temperature variations, it avoids deformation of the packaging box due to thermal expansion and contraction. The vent 150 is located on the side of the box, preventing dust, liquids, and other foreign objects from easily entering the box without affecting its appearance. The small size of the vent does not compromise the structural strength of the hexahedral packaging box 10 and ensures stability during stacking, balancing functionality and aesthetics, and enhancing the practicality and reliability of the packaging box.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
