Description

Technical Field

[0001] This utility model relates to the field of blister box technology, and in particular to a heat-insulating, pressure-resistant, and shock-proof blister box. Background Technology

[0002] Blister boxes are plastic packaging boxes produced using a vacuum forming process. They are primarily used to protect and display products. The manufacturing process involves heating a flat sheet of rigid plastic until it softens, then vacuum-forming it onto a mold surface, and finally cooling it to form the desired shape. Blister boxes offer advantages such as high transparency, lightweight portability, strong protection, low cost, and environmental recyclability. They clearly display products, attract consumer attention, and are easy to carry and store.

[0003] Chinese utility model patent CN214296901U discloses a fold-resistant reinforced blister packaging box, including an outer box, an inner box that is heat-fused to the inside of the outer box, a horizontal support plate that is fixedly bonded to the bottom surface of the inner box, and the top surface of the horizontal support plate that is fixedly bonded to the bottom of the inner box, vertical support plates that are fixedly bonded to the inner walls of the outer box, and one side of the vertical support plate that is fixedly bonded to the four walls of the inner box, a partition is provided inside the inner box, a top cover is provided at the top of the outer box, and a lower buckle is fixedly connected to the front of the outer box near the center of the top.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the dividers in the inner box of the packaging box are cross-shaped, dividing the inner box into four storage spaces. The size of the storage spaces is difficult to adjust according to the size of the products to be stored. When storing products of different sizes, it is necessary to change to different models of blister packaging boxes, which is inconvenient. Utility Model Content

[0005] To solve the above problems, this utility model provides a heat-insulating, pressure-resistant, and shock-proof blister box.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a heat-insulating, pressure-resistant, and shock-absorbing blister box, comprising an outer packaging box, an inner packaging box disposed within the outer packaging box, and a lid disposed on the top of the outer packaging box. An annular frame is fixed to the top of the inner packaging box, and snap-fit ​​grooves are provided on the inner walls of the annular frame. Multiple horizontal and vertical partitions are disposed within the inner packaging box. The width of the horizontal partitions is greater than the width of the vertical partitions, and the thickness of the horizontal partitions is equal to the thickness of the vertical partitions. A clearance groove is provided at the bottom of each horizontal partition to engage with the vertical partitions. Horizontal blocks are integrally formed at both ends of each horizontal partition near their top positions, and vertical blocks are integrally formed at both ends of each vertical partition near their top positions.

[0007] By adopting the above technical solution, multiple snap-fit ​​slots are evenly spaced on the inner side of the ring frame. The thickness of the horizontal block and the thickness of the vertical block are equal to the width of the snap-fit ​​slots. The staff can adjust the position of the horizontal and vertical partitions according to the size of the stored products. While ensuring the stability of product storage, it reduces space waste and expands the application range of blister boxes.

[0008] Furthermore, the top of the outer box of the packaging box is fixed with an annular protrusion, and the bottom of the box cover is provided with an annular groove that engages with the annular protrusion. The bottom of the box cover abuts against the top of multiple horizontal partitions.

[0009] By adopting the above technical solution, the annular protrusion and the annular groove are engaged, which makes it easy for workers to detachably connect the box lid to the outer box of the packaging box. The bottom of the box lid abuts against the horizontal partition, which plays a good limiting role and helps to ensure the stability of the horizontal partition and the vertical partition in the inner box of the packaging box.

[0010] Furthermore, an annular heat insulation layer is attached and fixed to the outer wall of the inner box of the packaging box.

[0011] By adopting the above technical solution, the setting of the annular heat insulation layer enhances the heat insulation effect of the inner box of the packaging box, which is conducive to improving the stability of the products stored in the inner box of the packaging box.

[0012] Furthermore, an anti-compression component is provided between the outer box and the inner box of the packaging box. The anti-compression component includes an annular bottom frame, a connecting rod fixed to the top of the annular bottom frame, and an annular top frame fixed to the upper end of the connecting rod. The inner and outer sides of the annular bottom frame and the inner and outer sides of the annular top frame respectively abut against the outer side of the annular heat insulation layer and the inner side of the outer box of the packaging box. Multiple connecting rods are provided.

[0013] By adopting the above technical solution, the annular bottom frame, connecting rod and annular top frame work together to achieve good structural reinforcement, enhance the structural stability and pressure resistance of the blister box, and improve the protection of the product inside the packaging box.

[0014] Furthermore, the inner box of the packaging box is provided with a shock-absorbing component, which includes bubble wrap laid on the bottom wall of the inner box.

[0015] Furthermore, the shock-absorbing component also includes a sponge layer disposed on top of the bubble pad, the bottom of the transverse partition is flush with the bottom of the longitudinal partition and abuts against the top of the sponge layer.

[0016] By adopting the above technical solution, the bubble wrap and the sponge layer work together to give the blister box a good shock absorption effect, which helps to protect the product inside the packaging box.

[0017] Furthermore, a heat insulation layer is attached and fixed to the bottom of the box lid.

[0018] By adopting the above technical solutions, the heat insulation effect of the blister box is enhanced, further improving the protection of the product.

[0019] Furthermore, the top of the box lid is integrally formed with splicing protrusions, and the bottom of the outer box of the packaging box is provided with splicing grooves that engage with the splicing protrusions.

[0020] By adopting the above technical solution, the splicing protrusions and splicing grooves are engaged, which facilitates the stacking of multiple blister boxes and ensures the stability of the stacked blister boxes.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This application reduces space waste and expands the application scope of blister boxes while ensuring product storage stability;

[0023] 2. In this application, the annular protrusion and the annular groove engage to facilitate the detachable connection of the box lid to the outer box of the packaging box by the staff. The bottom of the box lid abuts against the horizontal partition, which plays a good limiting role and helps to ensure the stability of the horizontal partition and the vertical partition in the inner box of the packaging box.
