Description

Technical Field

[0001] This utility model relates to the technical field of foam packaging boxes, specifically a slotted foam packaging box cover. Background Technology

[0002] Foam packaging boxes are box-shaped packaging containers made of polymer materials containing a large number of air bubbles. Their interior contains many tiny pores, which give them lightweight, sound-insulating, and shock-absorbing properties. Foam packaging boxes are commonly used for transporting fruits, vegetables, and fresh food, thus requiring foam box lids for sealing. Existing slotted foam box lids, which are simply inserted, are prone to detaching and falling off during transport, resulting in poor performance.

[0003] According to Chinese Patent No. CN216510170U, a slot foam packaging box cover includes a cover body and an insertion component. The bottom of the cover body is connected to the insertion component, and ventilation holes are provided on both sides of the cover body. The insertion component includes multiple insertion blocks, and the interior of each insertion block is provided with a receiving groove. A reinforcing plate is attached to the interior of the receiving groove, and multiple sharp protrusions are connected to the reinforcing plate. A rubber bladder is attached to the interior of the receiving groove, and the interior of the rubber bladder is filled with adhesive. The height of the receiving groove is two-thirds of the height of the insertion block. The receiving groove matches the reinforcing plate, and the protrusions of the rubber bladder are connected to the receiving groove. The rubber bladder is made of flexible rubber.

[0004] In the above scheme, multiple insert blocks are inserted into the slots of the box body. When the insert blocks are inserted into the slots, the flexible rubber bladder protrusions contact the inner wall, and the other side of the rubber bladder is squeezed to contact the spike protrusions. The spike protrusions puncture the rubber bladder, and the adhesive inside the rubber bladder flows out, which glues the insert blocks to the box body and positions and installs the cover.

[0005] The above solution still has the following drawbacks: foam packaging boxes are made of polymer materials containing a large number of bubbles. They are lightweight and easily deformed. Inserting multiple reinforcing plates one by one increases time costs and can also easily cause the box to deform. Utility Model Content

[0006] The purpose of this utility model is to provide a slotted foam packaging box cover to solve the problem that foam packaging boxes are made of polymer materials containing a large number of air bubbles, which are lightweight and easily deformed. Inserting multiple reinforcing plates one by one increases time costs and is also prone to box deformation.

[0007] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a slotted foam packaging box cover, including a box cover, the box cover being disposed on the top surface of a foam box, limiting holes being opened on both the left and right sides of the box cover, a slider being slidably disposed inside the limiting holes, first limiting grooves being opened on both the left and right sides of the foam box, the slider being inserted into the inside of the first limiting grooves, a first webbing being disposed inside the limiting holes, a first adhesive being fixed to one side of the bottom surface of the first webbing, and the first adhesive being adhered to one side of the top surface of the slider.

[0008] Preferably, a second webbing is provided on the inner top surface of the limiting hole, and a second adhesive is fixed on one side of the top surface of the second webbing, and the second adhesive is bonded to the inner top surface of the limiting hole.

[0009] Preferably, the upper surface of the limiting hole has a cavity, the upper surface of the second webbing covers the leakage port of the cavity, and the cavity contains glue.

[0010] Preferably, the inner top surface of the box lid has a groove, and the top surface of the foam box is inserted into the inside of the groove.

[0011] Preferably, two protruding teeth are fixed on both the left and right sides of the foam box, and two second limiting grooves are opened on each of the left and right sides of the inside of the box lid. The outer wall of the protruding teeth is adapted to the inner wall of the second limiting groove.

[0012] Preferably, the first webbing is a ribbon or satin ribbon, and the second webbing is a ribbon or satin ribbon.

[0013] Compared with the prior art, a slotted foam packaging box cover adopting the above technical solution has the following characteristics:

[0014] Beneficial effects:

[0015] 1. In use, the operator inserts the lid into the foam box. Then, the operator pushes the sliders located on the left and right sides of the lid inwards. The sliders pass through the limiting holes and are inserted into the first limiting groove. When the lid needs to be opened, the first webbing is pulled outwards. Because the first webbing is attached to the top side of the slider by the first adhesive, when the first webbing drives the slider outwards to disengage from the first limiting groove, the lid can be directly pulled out. This simple push-pull operation enables the opening and closing of the foam box. Furthermore, the sliders and the foam box are made of the same material, improving work efficiency while saving costs. The first webbing used is a silk ribbon, which is lightweight, soft, and low-cost, and will not damage the lid or the foam box. It is also easy for operators to use, improving work efficiency.

[0016] II. During use, when the foam box needs to be protectively sealed for long-distance transportation, the worker tears off the first webbing and pushes the sliders located on the left and right sides of the box lid inward again. The sliders pass through the limiting holes and are inserted into the first limiting groove. At this time, the second webbing is pulled out, and the glue inside the cavity leaks out, sticking the sliders to the inside of the limiting holes, ensuring the safety of the contents inside the foam box during transportation. The simple operation can complete the protective sealing of the foam box, greatly improving work efficiency. The second webbing used is a ribbon, which is lightweight, soft, and low in cost. It will not damage the box lid and the foam box, and it is easy for workers to operate, improving work efficiency. The glue stored inside the cavity is latex glue, which is an environmentally friendly glue with good adhesion and flexibility. After the latex glue dries, the adhesive strength is high, which can ensure a strong bond between the foams. In addition, the evaporation of moisture after the latex glue dries will not have an adverse effect on the foam.

[0017] Third, during use, when the lid is inserted into the foam box, the two protruding teeth on both sides above the foam box slide into the second limiting groove on both sides inside the lid until the top surface of the foam box is inserted into the inside of the groove, ensuring that the limiting hole corresponds to the first limiting groove, which facilitates the sliding block to be pushed in and improves work efficiency.

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1-4As shown, a slotted foam packaging box cover includes a box cover 1, which is disposed on the top surface of a foam box 12. The box cover 1 is made of foam. Limiting holes 2 are provided on both the left and right sides of the box cover 1. A slider 3 is slidably disposed inside the limiting holes 2. The slider 3 is made of foam. First limiting grooves 9 are provided on both the left and right sides of the foam box 12. The slider 3 is inserted into the first limiting grooves 9. A first webbing 4 is disposed inside the limiting holes 2. A first adhesive 5 is fixed to one side of the bottom surface of the first webbing 4. The first adhesive 5 is bonded to one side of the top surface of the slider 3. The first webbing 4 is a ribbon.

[0025] In use, the staff inserts the lid 1 onto the foam box 12. At this time, the staff pushes the sliders 3 located on the left and right sides of the lid 1 inward. The sliders 3 pass through the limiting hole 2 and are inserted into the first limiting groove 9. When it is necessary to open the lid 1, the first webbing 4 is pulled outward. Because the first webbing 4 is attached to the top side of the slider 3 by the first adhesive 5, when the first webbing 4 drives the slider 3 to slide outward until it is disengaged from the first limiting groove 9, the lid 1 can be pulled out directly. The simple push and pull operation can realize the closing and opening operation of the foam box 12. At the same time, the slider 3 and the foam box 12 are made of the same material, which saves costs while improving work efficiency.

[0026] The first webbing 4 used is a silk ribbon, which is lightweight, soft, and low in cost. It will not damage the box lid 1 and the foam box 12, and it is easy for workers to operate, thus improving work efficiency.

[0027] like Figures 2-4 As shown, a second webbing 6 is provided on the inner top surface of the limiting hole 2. A second adhesive 7 is fixed on one side of the top surface of the second webbing 6. The second adhesive 7 is bonded to the inner top surface of the limiting hole 2. A cavity 8 is opened on the inner top surface of the limiting hole 2. The top surface of the second webbing 6 covers the leakage port of the cavity 8. Glue is stored inside the cavity 8. The second webbing 6 is a ribbon.

[0028] In use, when the foam box 12 needs to be protected and sealed for long-distance transportation, the staff tears off the first webbing 4 and pushes the sliders 3 located on the left and right sides of the box cover 1 inward again. The sliders 3 pass through the limiting hole 2 and are inserted into the inside of the first limiting groove 9. At this time, the second webbing 6 is pulled out, and the glue inside the cavity 8 leaks out, sticking the sliders 3 to the inside of the limiting hole 2, ensuring the safety of the contents inside the foam box 12 during transportation. The simple operation can complete the protective sealing of the foam box 12, which greatly improves the efficiency of the work.

[0029] The second webbing 6 used is a ribbon, which is lightweight, soft, and low in cost. It will not damage the box lid 1 and the foam box 12, and it is easy for staff to operate, thus improving work efficiency.

[0030] The adhesive stored inside cavity 8 is latex adhesive, which is an environmentally friendly adhesive with good adhesion and flexibility. After drying, the adhesive has high bonding strength, which can ensure a strong bond between the foams. In addition, the evaporation of moisture after the latex adhesive dries will not have an adverse effect on the foam.

[0031] like Figures 2-3 As shown, a groove 13 is provided on the inner top surface of the box cover 1, and the top surface of the foam box 12 is inserted into the groove 13. Two protruding teeth 10 are fixed on both the left and right sides of the foam box 12. Two second limiting grooves 11 are provided on each of the left and right sides of the inner surface of the box cover 1. The outer wall of the protruding teeth 10 is adapted to the inner wall of the second limiting groove 11.

[0032] In use, when the lid 1 is inserted into the foam box 12, the two protruding teeth 10 on both sides above the foam box 12 slide into the second limiting groove 11 on both sides inside the lid 1 until the top surface of the foam box 12 is inserted into the inside of the groove 13, ensuring that the limiting hole 2 corresponds to the first limiting groove 9, which facilitates the pushing of the slider 3 and improves work efficiency.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
