Description
TECHNICAL FIELD
[0001] The utility model relates to product outer package technical field especially a stable type packing box. BACKGROUND
[0002] In the existing packing box structure, folding side plates are usually adopted to realize the convenience of packaging and the space saving of transportation.
[0003] However, when the top of the packing box is designed as a raised structure, the side plates cannot support the raised part due to the folding design. Although some improved packing boxes add front plate structures to provide support by contacting the top, the folding connection mode of the two side plates still causes displacement under pressure, which reduces the support stability. In particular, when containing special-shaped articles, bearing external stacking pressure or being subjected to plastic packaging, the weak support parts of the existing structure are prone to collapse and deformation, affecting the structural integrity of the packing box and the protection effect of the contents. In addition, the existing solutions often compensate for defects by adding internal fillers or complex support structures, which not only increases the material cost but also reduces the packaging efficiency.
[0004] Therefore, there is an urgent need for a new packing box structure that can effectively improve the support strength of the raised top part without significantly increasing production costs. SUMMARY
