Description

Technical Field

[0001] The utility model relates to the technical field of box-type sets, in particular to a box bottom structure of a box-type set. Background Art

[0002] At present, the box type used in the TV industry uses corrugated cardboard at the bottom, which is manually folded and formed on the production line, and then fixed with BOPP tape or locks, and then loaded with the bottom liner for use. This method has the disadvantages of poor moisture resistance, requiring one station and personnel for folding and forming on the production line, and the bottom of the box is easily deformed, which affects the automatic production line of box sets. Utility Model Content

[0003] In order to solve the problems existing in the prior art, the purpose of the utility model is to provide a box bottom structure of a nested box type. The utility model replaces the corrugated cardboard of the box bottom by laminating the lower liner, thereby achieving the purpose of reducing costs and improving efficiency.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a box bottom structure of a box-shaped box, including a lower liner located at the box bottom of the box-shaped box, the bottom surface of the lower liner and the surrounding of the bottom are covered with a composite film.

[0005] As a further improvement of the present invention, the color of the composite film material is consistent with the color of the carton on the box-type box body.

[0006] As a further improvement of the utility model, the height of the composite film covering the four sides of the bottom of the lower liner is 100mm-150mm.

[0007] As a further improvement of the present invention, the composite film is a composite film of PET and OPP, and has a thickness of 0.06 mm-0.1 mm.

[0008] As a further improvement of the present invention, the bottom structure of the box set is applied to TV products in the size range of 65-75.

[0009] The beneficial effects of the utility model are:

[0010] (1) Reduced material costs, reduced labor costs, reduced site usage area, and reduced factory process management.

[0011] (2) Even if the lower pad is cracked or disconnected after falling, the adhesive properties of the laminated composite film can fix the EPS in place, avoiding appearance problems such as foam dispersion and chipping.

[0012] (3) Utilize the barrier properties of composite film materials to improve moisture-proof performance.

[0013] (4) Solve the shortcomings of corrugated box bottom being easily deformed and affecting the automatic production line of box sets. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0021] Example

[0022] like Figure 1-Figure 4 As shown in the figure, a box bottom structure of a nested box is suitable for the box bottom of the nested box type, that is, the size segment of 65 and above. At the same time, considering that the size of 85 and above is inconvenient to carry after removing the packing tape, it is necessary to retain the PP connecting buckle to connect the box body and the bottom, so the actual application range is considered to be the size segment of 65-75.

[0023] In specific implementation, the bottom of the lower pad 1 is covered with a film, that is, covered with a composite film 2 to replace the bottom of the corrugated cardboard box. The coverage includes the bottom and surrounding of the lower pad 1, and the height is in the range of 100-150mm.

[0024] The film material is a composite film 2 of PET and OPP with good tensile strength and wear resistance, with a thickness of 0.06-0.1mm and an acrylic pressure-sensitive adhesive on the back; the color of the film material can be selected, preferably close to the color of the carton surface paper to improve the visual effect.

[0025] The utility model has passed a full set of transportation and machine strength test verifications, and the test results are qualified. After falling, the EPS corners of the lower liner 1 are cracked, and will not fall off or scatter under the effect of the coating, and has passed the machine strength related experiments.

[0026] Wear resistance comparison: After being dragged on smooth ground for 50 meters and rough ground for 50 meters, the coating has no obvious damage and meets the conditions for use.

[0027] Moreover, the lamination method is cheaper than the corrugated cardboard method, reduces one person on the production line, does not require the folding and pasting of corrugated cardboard on the production line, and reduces site usage area and factory process management.

[0028] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
