Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, specifically relating to a positioning packaging structure with support function and a packaging box. Background Technology

[0002] In the food packaging industry, existing technologies generally employ a method of individually packaging food items and then placing them inside a box liner to protect fragile foods such as mooncakes, pastries, and biscuits. However, current liner structures are typically simple flat designs, placed directly inside the box. The packaged items rely solely on gravity to remain stationary on the liner surface, lacking reliable horizontal and vertical restraint mechanisms. During transportation and handling, external vibrations, impacts, or tilting can easily cause disordered displacement of the packaged items on the liner, manifesting as bouncing up and down or sliding left and right. This displacement not only leads to collisions between food items but can also cause repeated friction or impacts between the food and the inner wall of the box, resulting in scratches, deformation, or even damage to the contents. Especially when the box contains multiple items, the liner cannot independently position each packaged item, significantly increasing the relative movement between items and multiplying the risk of damage. These shortcomings make existing packaging structures ineffective in addressing the challenges of protecting fragile foods in complex logistics environments and long-term storage, severely impacting product integrity. Utility Model Content

[0003] The purpose of this application is to provide a positioning packaging structure and packaging box with supporting function, which realizes the precise positioning of the packaged object in the horizontal direction and the buffer support in the vertical direction, effectively preventing displacement, collision and damage during transportation, while improving the stability and protective performance of the packaging structure.

[0004] One embodiment of this utility model provides a positioning packaging structure with a supporting function, which is installed in a box consisting of an outer box and an inner box, including an inner liner, several positioning baffles and supporting wings. The inner lining panel has multiple placement slots for positioning and placing the packaged object in the inner box; The positioning guard is arranged around the lower surface of the inner lining plate, and the positioning guard fits with the inner wall of the inner box to position the inner lining plate in the horizontal direction. The support wing is set on the upper surface of the inner liner, and the support wing fits with the inner wall of the inner box, and its top end abuts against the inner side of the outer box sleeve, so as to maintain a predetermined vertical distance between the inner liner and the outer box sleeve.

[0005] Furthermore, this application also proposes that the support wing is located at the center of the edge of the inner liner plate; and the positioning baffle is located on both sides of the support wing.

[0006] Furthermore, this application also proposes that the width of the support wing is 1.5-3cm and the width of the positioning baffle is 1-2cm.

[0007] Furthermore, this application also proposes that the placement slot be configured as circular, polygonal, or rectangular; The size of the placement slot is smaller than the maximum size of the object being packaged.

[0008] Furthermore, this application also proposes that the inner lining plate, positioning baffle, and supporting wing are an integral structure.

[0009] Furthermore, this application also proposes that the inner lining, positioning guards, and support wings are made of rigid cardboard, composite paperboard, or plastic sheet.

[0010] Furthermore, this application also proposes that a handle hole be provided in the central area of ​​the inner lining panel for removing the inner lining panel from the inner box.

[0011] Furthermore, this application also proposes a packaging box, including an outer box sleeve, an inner box body, and the aforementioned positioning packaging structure with supporting function, wherein the inner lining is housed within the inner box body.

[0012] Furthermore, this application also proposes that the outer box sleeve at least has a transparent top surface, and that the outer box sleeve and the inner box body are nested together to form a display window for displaying the packaged object contained in the inner box body.

[0013] Furthermore, this application also proposes that the inner box body is provided with a pull hole or pull strap on the side, the pull hole or pull strap being used to pull the inner box body out of the outer box sleeve.

[0014] As can be seen from the above, the positioning packaging structure and packaging box with supporting function provided by this application can achieve the following technical effects: the positioning edge and the inner wall of the inner box are matched to achieve precise horizontal positioning, and the supporting wing abuts against the inner side of the outer box to form a vertical buffer space, which effectively solves the problem of disordered displacement and direct transmission of external pressure of the packaged object during transportation. It has achieved precise horizontal positioning and vertical buffer support of the packaged object, effectively preventing displacement, collision and damage during transportation, and improving the stability and protective performance of the packaging structure.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please refer to Figures 1-5 One embodiment of this utility model provides a positioning packaging structure with a supporting function, which is installed in a box consisting of an outer box 4 and an inner box 5, including an inner liner 1, several positioning baffles 2 and supporting wing pieces 3. The inner lining 1 is provided with multiple placement slots 6 for positioning and placing the packaged object 7 in the inner box 5; The positioning baffle 2 is arranged around the lower surface of the inner liner 1, and the positioning baffle 2 cooperates with the inner wall of the inner box 5 to position the inner liner 1 in the horizontal direction. The support wing 3 is disposed on the upper surface of the inner liner 1. The support wing 3 fits with the inner wall of the inner box 5, and its top end abuts against the inner side of the outer box sleeve 4, so as to maintain a predetermined vertical distance between the inner liner 1 and the outer box sleeve 4.

[0020] Understandably, the inner liner 1 can be understood as a basic structure supporting the packaged object 7. Its main function is to achieve precise positioning of the packaged object 7 through multiple placement slots 6 set on it. In practical applications, the placement slots 6 can be formed by stamping, cutting, or molding, for example, by using rectangular grooves, arc grooves, or other groove designs adapted to the shape of the packaged object. The purpose is to restrict the free movement of the packaged object 7 in the horizontal direction. The support wing 3 refers to the structure set on the upper surface of the inner liner 1. Its main function is to control the vertical distance between the inner liner 1 and the outer box sleeve 4 by cooperating with the inner wall of the inner box 5 and the inner side of the outer box sleeve 4. In practical applications, the support wing 3 can be fixed to the inner liner 1 by folding, inserting, or pasting. The top of the support wing 3 can be designed as a flat surface, an arc surface, or other structure adapted to the shape of the inner side of the outer box sleeve 4 to ensure stable contact with the inner side of the outer box sleeve 4.

[0021] In this embodiment, the coordinated design of the inner liner 1, the positioning baffle 2, and the support wing 3 solves the problem of damage caused by the up-and-down or left-and-right swaying of the packaged object 7 during transportation. Compared with the prior art where the inner liner is placed directly inside the packaging box, this application achieves horizontal fixation of the inner liner 1 through the cooperation of the positioning baffle 2 with the inner wall of the inner box 5, while providing vertical support through the cooperation of the support wing 3 with the inner side of the outer box sleeve 4. This effectively restricts the free movement of the packaged object 7 during transportation, meeting the protection needs of fragile food during transportation and storage. In practical applications, the width of the support wing 3 is set according to the height of the packaged object. For example, the width of the support wing 3 is designed to be greater than half the height of the packaged object, so that the packaged object can simultaneously satisfy the effects of fixation and display, and the predetermined vertical distance between the inner liner 1 and the outer box sleeve 4 is between 1.5-3cm.

[0022] Please refer to Figures 1-3 Furthermore, this application proposes that the support wing 3 is located at the center of the edge of the inner liner plate 1; and the positioning baffle 2 is located on both sides of the support wing 3.

[0023] Understandably, the support wing 3 refers to the structural component used to provide vertical support force. It can be made of a material with a certain degree of rigidity, such as rigid cardboard or plastic sheet. By being precisely set at the center of the edge of the inner liner 1, it can ensure that the support force is evenly distributed along the edge and avoid the inner liner 1 from tilting due to the offset of the force point. The positioning baffle 2 refers to the constraint component used to limit horizontal displacement. It can be made of the same material as the support wing 3. By being symmetrically arranged on both sides of the support wing 3, it forms a two-way horizontal constraint mechanism, thereby effectively resisting the impact of external forces from the left and right directions.

[0024] In this embodiment, by precisely positioning the support wing 3 at the center of the edge of the inner liner 1, the contact effect with the inner side of the outer box 4 is optimized, allowing the support wing 3 to distribute pressure more accurately, thereby reliably maintaining the predetermined vertical distance between the outer box 4 and the inner liner 1, effectively preventing the packaged object 7 from shaking up and down; at the same time, the positioning guards 2 are symmetrically arranged on both sides of the support wing 3, strengthening the structure of the inner liner 1 to prevent deformation, while ensuring that the positioning guards 2 provide balanced constraint force in the horizontal direction; the above structural design not only improves the stability of the inner liner 1 during transportation, but also significantly reduces the risk of displacement of the packaged object 7 due to vibration. In addition, the layout of the support wing 3 and the positioning guards 2, together with the placement groove 6 on the inner liner 1, forms an overall positioning frame, further enhancing the stability of the packaging structure.

[0025] This application further proposes that the width of the support wing 3 is 1.5-3cm and the width of the positioning baffle 2 is 1-2cm. Understandably, the width range of the support wing 3 is set to 1.5-3cm. This width range provides sufficient contact area to maintain the predetermined vertical distance between the inner liner 1 and the outer casing 4, while avoiding insufficient support due to excessive narrowness or structural deformation due to excessive width. The width range of the positioning baffle 2 is controlled at 1-2cm, optimizing its fit accuracy with the inner wall of the inner casing 5. This ensures reliable horizontal constraint and avoids loose positioning due to excessive narrowness or affecting installation smoothness due to excessive width. In this embodiment, the design of the width parameters described above enables the support wing 3 and the positioning baffle 2 to work together effectively, enhancing the overall structure's resistance to shaking during transportation vibrations, thereby better meeting the protection needs of fragile foods during transportation and storage.

[0026] This application further proposes that the placement slot 6 be configured as circular, polygonal, or rectangular; the size of the placement slot 6 is smaller than the maximum size of the packaged object 7.

[0027] Understandably, circular, polygonal, or rectangular shapes can be adapted to different geometric shapes of the packaged objects 7, thereby ensuring a tight fit between the trough and the object. At the same time, the size of the placement trough 6 is set to be smaller than the maximum size of the packaged object 7. The purpose is to form continuous frictional resistance and elastic support in the vertical direction through appropriate interference fit, so as to prevent the object from bouncing or sinking due to external impact.

[0028] In this embodiment, the geometry and size parameters of the placement slot 6 are optimized to improve the positioning stability of the packaged object 7. For example, a circular slot is adapted to spherical or cylindrical items to achieve uniform circumferential constraint, a polygonal slot is used to ensure edge fit for regular geometric items, and a long slot provides linear support for slender items. This slot selection mechanism based on the shape of the object not only avoids gaps caused by shape mismatch, but also enhances the anti-slip capability in the horizontal direction through contour matching. In addition, the slight squeezing effect driven by size difference makes the object receive elastic support when embedded in the slot, thereby effectively suppressing the risk of dynamic displacement during transportation.

[0029] Please refer to Figures 2-3 Furthermore, this application proposes that the inner liner 1, the positioning baffle 2, and the supporting wing 3 are an integral structure.

[0030] Understandably, an integrated structure refers to the integral molding of the inner liner 1, the positioning flange 2, and the support wing 3 into an inseparable whole component; in practical applications, this structure can be achieved through processes such as die cutting, injection molding, or bending.

[0031] This application further proposes that the inner lining 1, the positioning edge 2, and the support wing 3 are made of rigid cardboard, composite paperboard, or plastic sheet.

[0032] Understandably, rigid cardboard refers to a paper material with high thickness and support performance, which can be achieved by pressing multiple layers of pulp and then surface treating it; composite paperboard can be understood as paperboard made of multiple layers of different materials or different support structures, such as corrugated paperboard, which improves the overall mechanical properties by laminating materials with different properties; plastic sheets, such as PET sheets, have good support performance and are easy to thermoform, and can be made into the required shape and structure through conventional processes such as vacuum forming and cutting.

[0033] In this embodiment, the moderate hardness and bending resistance of the cardboard enable it to effectively cope with short-term load pressure; the multi-layer structure of the composite paperboard provides additional compression resistance, making it particularly suitable for scenarios requiring long-term storage; and the plastic sheet ensures that the integrated structure maintains stable physical properties under various environmental conditions.

[0034] Please refer to Figures 2-3 Furthermore, this application proposes that the inner lining plate 1 is provided with a handle hole 8 in the central area, the handle hole 8 being used to pull the inner lining plate 1 out of the inner box 5.

[0035] Understandably, the handle hole 8 refers to an opening structure set in the central area of ​​the inner lining plate 1, which can be implemented in the form of a circle, ellipse or rectangle. In practical applications, the position of the handle hole 8 is selected based on the consideration of the center of gravity distribution of the inner lining plate 1 to ensure that the applied tensile force can be evenly applied to the center of the structure.

[0036] In this embodiment, the handle hole 8 is designed with a dedicated opening for finger insertion, allowing the user to directly apply vertical pulling force, thereby simplifying the process of removing the inner liner 1.

[0037] This application further proposes a packaging box, including an outer box sleeve 4, an inner box body 5, and the aforementioned positioning packaging structure with supporting function, wherein the inner liner 1 is housed within the inner box body 5.

[0038] In this embodiment, by combining the inner liner 1 with the positioning guard 2 and the support wing 3 in a collaborative design, the problem of shaking and damage caused by the inability of the inner liner to secure fragile food during transportation and storage is effectively solved, achieving the effect of securing the packaged object 7 in all directions. Specifically, the positioning guard 2 is arranged around the lower surface of the inner liner 1 and cooperates with the inner wall of the inner box 5 to achieve precise positioning of the inner liner 1 in the horizontal direction. The support wing 3 is arranged on the upper surface of the inner liner 1, and its top end abuts against the inner side of the outer box sleeve 4 to ensure that the inner liner 1 and the outer box sleeve 4 maintain a predetermined vertical distance, thereby restricting the vertical movement of the packaged object 7. In addition, the multiple placement slots 6 provided on the inner liner 1 can be tightly positioned according to the shape and size of the packaged object 7, further enhancing the stability of the overall structure.

[0039] This application further proposes that the outer box 4 is made of transparent material at least on the top surface, and the outer box 4 and the inner box 5 are nested together to form a display window for displaying the packaged object 7 contained in the inner box 5.

[0040] Understandably, transparent material refers to material that allows light to pass through and clearly observe the internal situation. It can be made of acrylic or transparent plastic, etc. The purpose is to optimize the display function of the packaging box so that users can directly view the internal items without opening the outer box 4. The display window refers to the visible area formed by precisely aligning the transparent material with the opening area of ​​the inner box 5. Its purpose is to provide an unobstructed observation window, thereby reducing structural displacement and item shaking caused by frequently opening the outer box 4.

[0041] In this embodiment, by setting a transparent material on the top surface of the outer box sleeve 4 and combining it with the nesting relationship between the outer box sleeve 4 and the inner box 5, an instant viewing function is achieved. Since the top surface is usually the direction of natural observation for users, especially when displayed on a shelf, the interior can be seen directly without adjusting the box angle. Therefore, the introduction of the transparent material significantly reduces the probability of damage to fragile food caused by repeated opening and closing. In addition, the display window formed by the nesting of the outer box sleeve 4 and the inner box 5 makes full use of the geometric fit between the two to ensure precise alignment between the transparent top surface and the opening area of ​​the inner box 5, thereby forming a clear and reliable observation window.

[0042] Please refer to Figure 1 This application further proposes that the inner box 5 is provided with a pull hole 9 or a pull strap on the side, the pull hole 9 or pull strap being used to pull the inner box 5 out of the outer box 4.

[0043] Understandably, the pull hole 9 refers to the through hole structure opened on the side of the inner box 5. It can be implemented in the form of a circle, ellipse or rectangle, etc., with the purpose of providing a force point for the user to insert their fingers and apply pull force. The pull strip can be understood as a flexible strip-shaped component fixed to the side of the inner box 5. It can be connected to the inner box 5 by sewing, pasting or embedding, etc., with the purpose of providing a better grip and more even pull force transmission.

[0044] In this embodiment, by integrating a pull-out hole 9 or a pull-out strap on the side of the inner box 5, the problem of difficulty in pulling out the inner box 5 is effectively solved. The pull-out structure is designed on the side because the side is convenient for user operation and does not affect other functions of the inner box 5. The pull-out hole 9, as an opening structure, allows fingers to be inserted directly to apply force, while the pull-out strap, as a flexible component, provides better grip and force transmission. The pull-out structure is set according to the side position so that the direction of the pulling force is consistent with the direction of movement of the inner box 5, avoiding jamming caused by lateral force. Through optimized structural design, the inner box 5 can slide smoothly out of the outer box 4.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
