AI Technical Summary
Existing foam packaging boxes require significant clamping force during handling to prevent slippage, resulting in high labor intensity for workers. At the same time, increased material thickness leads to higher costs, and structural strength cannot be adequately addressed.
Heat shrink film is wrapped around the lid and outer surface of the packaging box, and thickened or pleated edges are formed on the sides. The thickened or pleated edges make it easy to lift, and the design with ventilation holes improves structural strength and saves materials.
It achieves increased structural strength of packaging boxes without increasing material thickness, reduces labor intensity for workers handling the boxes, and ensures vegetable freshness through ventilation holes, all at a low cost.

TECHNICAL FIELD
[0001] The utility model relates to the packaging field, concretely relates to a film-coated packaging box convenient to lift. BACKGROUND
[0002] Foam packaging box is common packaging material, can be used to package vegetables, and the vegetables are transported conveniently. The packaging box needs to be carried during loading and unloading. In the past, the workers hold the packaging box from the bottom of the box body to lift the packaging box, which makes the bending range large and the operation relatively hard. If the packaging box is held from the side, a large clamping force is needed to prevent the palm from sliding on the side of the box body.
[0003] The existing packaging box needs to use a thick wall thickness to ensure the structural strength. This requires thick materials to make, increasing the cost. If the thickness is reduced without taking other strengthening measures, the structural strength cannot be guaranteed.
[0004] Therefore, the present application is produced in view of the above-mentioned defects in the prior art. SUMMARY
[0005] The main purpose of the utility model is to provide a film-coated packaging box convenient to lift, which has the characteristics of improving the strength of the packaging box and facilitating the lifting of the packaging box, can save material cost and reduce the labor intensity of workers.
[0006] In order to achieve the above purpose, the solution of the utility model is as follows:
[0007] A film-coated packaging box convenient to lift, comprising a cover body and a box body, the cover body is combined on the upper part of the box body to form a box cover combination, and the outer surface of the box cover combination is covered with a heat shrinkable film; the heat shrinkable film forms an opening on the opposite sides of the box cover combination, and the edge of the opening forms a thickened edge or a folded edge for the user to lift.
[0008] Further, the thickened edge is integrally formed on the edge of the heat shrinkable film.
[0009] Further, the thickened edge is folded by at least two layers of heat shrinkable film.
[0010] Further, the heat shrinkable film is made of transparent material.
[0011] Further, the heat shrinkable film on the other surface without the opening is bonded to the box cover combination.
[0012] Further, the box cover combination is in the shape of a rectangular parallelepiped.
[0013] Further, the box body is provided with a ventilation hole.
[0014] Further, the cover and the box are made of foamed plastic material.
[0015] With the above structure, the film-coated packaging box of the present application has at least the following advantages:
[0016] I. By attaching a layer of heat-shrinkable film to the outer surface of the lid assembly, the structural strength of the packaging box is improved, and the cover and the box are prevented from separating. Due to the improved structural strength, the wall thickness can be designed to be smaller, thereby saving materials. The opening is provided on the side of the heat-shrinkable film, and the thickened edge of the opening edge facilitates the workers to lift the packaging box.
[0017] II. The thickened edge is formed by folding the edge of the heat-shrinkable film, without the need to add new components, and the cost is low. By bonding the heat-shrinkable film to the surface of the lid assembly, the structural strength of the film-coated packaging box is further improved.
[0018] III. The air vents serve the purpose of allowing the vegetables to breathe, which is conducive to ensuring the freshness of the vegetables.
[0019] Compared with the prior art, the film-coated packaging box of the present application is provided with a film and an opening with a thickened edge on the side of the film, which ensures the strength of the packaging box and facilitates the workers to lift the packaging box.

[0027] In order to further explain the technical scheme of the present application, the present application will be described in detail below through specific embodiments.
[0028] As Figures 1 to 4As shown, it is a kind of convenient lifting's film packaging box of the utility model, including cover body 1 and box body 2, the cover body 1 covers in the upper portion of box body 2 to form the lid combination body;Preferably, the cover body 1 and box body 2 are made of foam plastic material.The outer surface of the lid combination body is covered with heat shrink film 3;The heat shrink film 3 is formed with opening 31 on the opposite sides of the lid combination body, and the edge of the opening 31 is formed with thickened edge 32 or crimped edge 33 for the user to lift.
[0029] In this way, the film packaging box of the utility model is convenient to lift, a layer of heat shrink film 3 is attached to the outer surface of the lid combination body, which improves the structural strength of the packaging box and avoids the separation of the cover body 1 and the box body 2. Due to the improved structural strength, the wall thickness can be designed to be smaller, thereby saving materials. The opening 31 is provided on the side of the heat shrink film 3, and the thickened edge 32 or the crimped edge 33 on the edge of the opening 31 facilitates the workers to lift.
[0030] Preferably, the thickened edge 32 is integrally formed on the edge of the heat shrink film 3. Further, as shown, Figure 4 The thickened edge 32 is folded from at least two layers of heat shrink film 3. The thickened edge 32 is formed by folding the edge of the heat shrink film 3, without the need to add new components, and the cost is relatively low. Preferably, the heat shrink film 3 is made of transparent material.
[0031] Alternatively, preferably, the thickened edge 32 is calendered; as Figure 5 The crimped edge is formed by W-shaped indentation on the edge of the heat shrink film, and after heat shrinkage, the crimped edge is formed on the edge of the opening. The crimped edge facilitates the user to hook the heat shrink film with fingers, thereby lifting the packaging box.
[0032] Further, the box body 2 is provided with a ventilation hole 21. The ventilation hole 21 serves to ventilate the vegetables, which is beneficial to ensure the freshness of the vegetables.
[0033] Preferably, the heat shrink film 3 on the other faces without the opening 31 is adhered to the lid combination body. By adhering the heat shrink film 3 to the surface of the lid combination body, the structural strength of the film packaging box is further improved. The heat shrink film 3 is provided with an opening corresponding to the ventilation hole 21.
[0034] Preferably, the lid combination body is in the shape of a rectangular parallelepiped. As shown, Figures 1-3 The opening 31 is located on the smaller two sides of the rectangular parallelepiped lid combination body.
[0035] Compared with the prior art, the utility model sets the film and the opening 31 with the thickened edge 32 on the side of the film, which ensures the strength of the packaging box and facilitates the workers to lift the packaging box.
