Technical Field
[0001] This utility model relates to the field of packaging, and in particular to an outer box packaging structure. Background Technology
[0002] Currently, gift boxes with slots commonly found on the market often have handles that, after being attached, are prone to falling off due to external pressure causing the handle head to flatten and deform, affecting their carrying and use. Utility Model Content
[0003] The purpose of this utility model is to provide an outer packaging structure that can effectively prevent the handle from coming off, and solves the problem that the handle head of the existing packaging box is easily detached after being flattened and deformed by external force after the handle is attached, which affects the use of the box.
[0004] The purpose of this utility model is achieved as follows: an outer packaging structure includes a box body and a handle. An inner cover plate and an outer cover plate are provided at the opening of the box body. A handle opening is provided on the outer cover plate. The inner cover plate has two handle holes and two through holes. The two handle holes are located between the two through holes. A connecting plate is provided at the through holes, and a limiting hole is provided on the connecting plate. A first baffle is provided at the handle hole, and a second baffle is provided on the limiting hole. The handle includes a handle strap and two handle heads. The middle part of the handle head is connected to the corresponding end of the handle strap. When the connecting plate is folded inward into the box body and abuts against the inner surface of the inner cover plate, the handle head can pass through the corresponding handle hole and the limiting hole in sequence and be limited to the inner side of the inner cover plate. The first baffle can be blocked on the inner side of the handle strap, and the second baffle can be blocked on the inner side of the handle strap and sandwiched between the handle strap and the handle head. Part of the handle strap can pass out through the handle opening.
[0005] In a preferred embodiment of the present invention, the side of the connecting plate near the limiting hole is connected to the edge of the through hole, and at least a portion of the side of the two first baffles near each other is connected to the edge of the corresponding handle hole; when the connecting plate is folded into the inside of the box and abuts against the inner surface of the inner cover plate, at least a portion of the side of the two second baffles near each other is connected to the edge of the corresponding limiting hole.
[0006] In a preferred embodiment of the present invention, the shape of the first baffle matches the shape of the handle hole and can completely cover the handle hole, and the shape of the second baffle matches the shape of the limiting hole and can completely cover the limiting hole.
[0007] In a preferred embodiment of this utility model, the limiting hole and the handle hole are both elongated oval holes, and the first baffle and the second baffle are both elongated oval pieces.
[0008] In a preferred embodiment of the present invention, the surface area of the first baffle is smaller than the cross-sectional area of the handle hole, and the surface area of the second baffle is smaller than the cross-sectional area of the limiting hole.
[0009] In a preferred embodiment of this utility model, the limiting hole and the handle hole are both oblong holes, and the first baffle and the second baffle are both rectangular pieces.
[0010] In a preferred embodiment of this utility model, the limiting hole and the handle hole are both elongated oval holes, and the first baffle and the second baffle are both arc-shaped pieces.
[0011] In a preferred embodiment of this utility model, the major axis of the oblong hole is 17mm-18mm and the minor axis is 4.5mm-5.5mm; the length of the arc plate along the major axis of the oblong hole is 11mm-12mm and the width along the minor axis of the oblong hole is 1mm-2mm.
[0012] In a preferred embodiment of this utility model, the shape of the connecting plate matches the shape of the through hole and can completely cover the through hole, or the surface area of the connecting plate is smaller than the cross-sectional area of the through hole.
[0013] In a preferred embodiment of this utility model, the through hole is a rectangular hole with rounded corners, and the connecting plate is a rectangular plate with rounded corners.
[0014] As described above, the outer packaging structure of this utility model can achieve integrated molding, allowing the operator to insert the handle in a very short time. By setting a connecting plate at the through hole, and setting a first baffle and a second baffle at the handle hole and the limiting hole on the connecting plate respectively, after the handle is inserted, the first and second baffles act as a barrier to the handle strap, creating resistance to the handle and effectively ensuring that the handle head does not come off and does not affect the carrying. By folding the connecting plate inwards towards the box body, the assembly gap of the handle can be reduced simultaneously. At the same time, the first and second baffles can be formed by cutting the handle hole and the limiting hole respectively. Each cut can form a pre-compression constraint during the assembly of the handle head, effectively avoiding the risk of detachment caused by flattening and deformation of the handle head due to external pressure. The fixing effect of the handle is strengthened from both structural strength and assembly stability dimensions, effectively ensuring structural stability. Meanwhile, the connecting plate can be formed from the waste material during the cutting process of the through hole, and the first and second baffles can be formed from the waste material during the cutting process of the handle hole and the limiting hole. The factory supplier does not need to add other materials to process the connecting plate, the first baffle and the second baffle, thus avoiding resource waste. The carton supplier's production process can also reduce a waste removal process, which can effectively improve production efficiency. Attached Figure Description

[0030] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.
[0031] like Figures 1 to 9 As shown, this application provides an outer packaging structure, including a box body and a handle 4. An inner cover plate 2 and an outer cover plate 3 are provided at the opening of the box body. A handle opening 31 is provided on the outer cover plate 3. The inner cover plate 2 has two handle holes 21 and two through holes 22. The two handle holes 21 are located between the two through holes 22. A connecting plate 23 is provided at the through holes 22. A limiting hole 231 is provided on the connecting plate 23. A first baffle 211 is provided at the handle hole 21. A second baffle 232 is provided on the limiting hole 231. The handle 4 includes a handle strap 4. 1 and two handle heads 42, the middle part of the handle head 42 is connected to the corresponding end of the handle strap 41; when the connecting plate 23 is folded into the inside of the box and abuts against the inner surface of the inner cover plate 2, the handle head 42 can pass through the corresponding handle hole 21 and the limiting hole 231 in sequence and be limited to the inner side of the inner cover plate 2, and the first baffle 211 can be blocked on the inner side of the handle strap 41, the second baffle 232 can be blocked on the inner side of the handle strap 41 and sandwiched between the handle strap 41 and the handle head 42, and part of the handle strap 41 can pass out through the handle opening 31.
[0032] Therefore, the outer packaging structure of this application can achieve one-piece molding, allowing the operator to insert the handle 4 in a very short time. By setting a connecting plate 23 at the through hole 22, and setting a first baffle 211 and a second baffle 232 at the limiting holes 231 on the handle hole 21 and the connecting plate 23 respectively, after the handle 4 is inserted, the first baffle 211 and the second baffle 232 block the handle strap 41, thereby creating resistance to the handle 4, effectively ensuring that the handle head 42 does not come out, and without affecting the lifting. By folding the connecting plate 23 inwards towards the inside of the box, the assembly gap of the handle 4 can be reduced simultaneously. Meanwhile, the first baffle 211 and the second baffle 232 can be formed during the cutting process of the handle hole 21 and the limiting hole 231, respectively. Each cut creates a pre-compression constraint during the assembly of the handle head 42, effectively preventing the risk of detachment caused by flattening and deformation due to external pressure on the handle head 42. This strengthens the fixing effect of the handle 4 from both structural strength and assembly stability perspectives, effectively ensuring structural stability. Furthermore, the connecting plate 23 can be formed from waste material during the cutting process of the through hole 22, and the first baffle 211 and the second baffle 232 can also be formed from waste material during the cutting process of the handle hole 21 and the limiting hole 231. The factory supplier does not need to add other materials to process the connecting plate 23, the first baffle 211, and the second baffle 232, avoiding resource waste. The carton supplier's production process can also reduce a waste removal step, effectively improving production efficiency.
[0033] In a specific implementation, the side of the connecting plate 23 near the limiting hole 231 is connected to the edge of the through hole 22, and at least a portion of the side of the two first baffles 211 near each other is connected to the edge of the corresponding handle hole 21. When the connecting plate 23 is folded into the inside of the box and abuts against the inner surface of the inner cover plate 2, at least a portion of the side of the two second baffles 232 near each other is connected to the edge of the corresponding limiting hole 231. This ensures that after the handle head 42 passes through the handle hole 21 and the limiting hole 231 in sequence, the first baffle 211 can be blocked on the inside of the handle strap 41, and the second baffle 232 can be blocked on the inside of the handle strap 41 and sandwiched between the handle strap 41 and the handle head 42.
[0034] The inner surface of the inner cover 2 mentioned here refers to the surface facing the inside of the box after the inner cover 2 is closed over the opening of the box. The inner side of the handle strap 41 is also the side facing the inside of the box. The structure of the handle 4 is an existing structure, refer to... Figure 6 The handle 4 can be made of a single injection-molded plastic part. The handle strip 41 is a long rectangular strip. The two handle holes 21 are arranged between the two through holes 22 along the length of the handle strip 41. The handle head 42 is a plate-like structure. The end of the handle strip 41 is connected to the middle of the handle head 42. The two parts of the handle head 42 located on both sides of the end of the handle strip 41 are bent at an obtuse angle. The connection between the handle head 42 and the handle strip 41 is flexible and bendable. The total thickness of the handle strip 41 and the handle head 42 is less than the width of the handle hole 21 and the limiting hole 231. When installing the handle 4, combined with... Figures 6 to 9 First, bend the connection between the handle head 42 and the handle strap 41 so that part of the handle head 42 fits snugly against the handle strap 41. Then, let the handle head 42 pass through the handle hole 21 and the limiting hole 231 in sequence, and then bend the handle head 42 again so that the second baffle 232 is sandwiched between the handle head 42 and the handle strap 41 to block the inside of the handle strap 41. The middle part of the handle strap 41 can be passed out through the handle opening 31 and arch outward to facilitate lifting.
[0035] Optionally, the first baffle 211 can at least partially block the handle hole 21, and the second baffle can at least partially block the limiting hole 231. When all the holes are blocked, the anti-slip limiting effect on the handle 4 is better; when the holes are partially blocked, while ensuring the anti-slip effect on the handle 4, it is easier for the operator to put the handle 4 through.
[0036] For example, refer to Figure 1 , Figure 2 and Figure 7 The shape of the first baffle 211 matches the shape of the handle hole 21 and can completely cover the handle hole 21. The shape of the second baffle 232 matches the shape of the limiting hole 231 and can completely cover the limiting hole 231. The specific shapes can be determined according to... Figure 2As shown, the handle hole 21 and the limiting hole 231 are both elongated holes, and the first baffle 211 and the second baffle 232 are both elongated plates. The surface area of the first baffle 211 is equal to the cross-sectional area of the limiting hole 231, and the surface area of the second baffle 232 is equal to the cross-sectional area of the limiting hole 231.
[0037] For example, refer to Figures 3 to 5 The surface area of the first baffle 211 is smaller than the cross-sectional area of the handle hole 21, and the surface area of the second baffle 232 is smaller than the cross-sectional area of the limiting hole 231. The specific shape can be determined according to... Figures 3 to 5 As shown, both the handle hole 21 and the limiting hole 231 are oblong holes, and both the first baffle 211 and the second baffle 232 are rectangular or arc-shaped pieces. In this example, the arc-shaped piece is less prone to bending than the rectangular piece, resulting in a better anti-slip effect. The arc-shaped piece has a slightly curved shape, as shown in the reference... Figure 4 and Figure 5 The straight edge of the inferior arc shape is connected to the edge of the corresponding handle hole 21 or the limiting hole 231, and the arc edge of the inferior arc shape protrudes into the corresponding hole.
[0038] The width of the handle 41 is generally 15mm-16mm. The dimensions of the handle hole 21 and the limiting hole 231 should be adapted to the handle hole 21. When both the handle hole 21 and the limiting hole 231 are oblong holes, the length of the major axis of the oblong hole is usually 17mm-18mm, and the length of the minor axis is 4.5mm-5.5mm. When both the first baffle 211 and the second baffle 232 are arc-shaped pieces, the length of the arc-shaped piece along the major axis of the oblong hole is 11mm-12mm, and the width along the minor axis of the oblong hole is 1mm-2mm. This facilitates the operator to insert the handle 4 and also prevents the handle 4 from coming out.
[0039] Optionally, the connecting plate 23 can at least partially block the through hole 22; that is, the shape of the connecting plate 23 matches the shape of the through hole 22 and can completely block the through hole 22, or the surface area of the connecting plate 23 is smaller than the cross-sectional area of the through hole 22. The specific shape can be determined according to… Figures 1 to 3 as well as Figure 7 The through hole 22 shown is a rectangular hole with rounded corners, and the connecting plate 23 is a rectangular plate with rounded corners.
[0040] Of course, the shape and size of the handle hole 21, the limiting hole 231, the through hole 22, the first baffle 211, the second baffle 232 and the connecting plate 23 can be determined according to actual needs. This embodiment is only an example.
[0041] The aforementioned box can be made of cardboard or other materials. When the box is unfolded... Figure 1As shown, it is a flat structure consisting of multiple side panels 11, multiple bottom flaps 12, and multiple top flaps 13. When folded, it can form a cuboid or cube structure. After folding, the top of the box has an opening. The first side of the inner cover 2 and the first side of the outer cover 3 are respectively connected to the opposite sides of the opening. An inner insertion hole 24 is provided at the connection between the opening and the inner cover 2. An inner insertion tongue 25 is provided on the side of the opening directly opposite the inner insertion hole 24. An outer insertion tongue 32 is provided on the second side of the outer cover 3 (this second side is opposite to the first side of the outer cover 3), and an outer insertion hole 33 is provided at the connection between the outer cover 3 and the outer insertion tongue 32. When folding and packaging, after the bottom and sides of the box are closed and fixed, first cover the inner cover 2 onto the opening, then cover the outer cover 3 onto the inner cover 2. The outer cover 3 and the inner cover 2 will overlap at least partially, so that the handle strap 41 on the inner cover 2 can correspond to the handle opening 31 on the outer cover 3. Then insert the outer tongue 32 into the hole, and then insert the inner tongue 25 into the outer hole 33.
[0042] The number of external tongues 32 and external holes 33 is the same, and the number of internal tongues 25 and internal holes 24 is the same. The specific number can be determined according to needs, for example, in this embodiment, according to... Figure 1 The number of external tongue 32 and internal tongue 25 shown are both two.
[0043] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
