Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box technology, specifically a highly airtight corrugated cardboard box. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to create corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging products, including calcium-plastic corrugated boxes. For over half a century, corrugated boxes have gradually replaced wooden crates and other transport packaging containers due to their superior performance and easy processing, becoming the mainstay of transport packaging. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated boxes are environmentally friendly products, benefiting both environmental protection and ease of loading and unloading.

[0003] The existing corrugated cardboard box structure is not strong enough. After long-term use, the tape joints at the bottom of the corrugated cardboard box are prone to cracking, which seriously affects the sealing performance of the corrugated cardboard box.

[0004] Therefore, a highly airtight corrugated cardboard box is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a corrugated cardboard box with high sealing performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A highly airtight corrugated cardboard box, comprising: Corrugated cardboard box body; The bottom of the corrugated cardboard box body is connected to a reinforcing base; The bottom of the reinforcing base is connected to a cross-shaped base support, and a connecting strip is fixed on the outer wall of the cross-shaped base support. A connecting plate is fixed to one end of the connecting strip near the corrugated cardboard box body. The connecting plate is connected to the corrugated cardboard box body with glue, and the cross-shaped bottom bracket is connected to the bottom of the reinforcing base with glue.

[0007] Preferably, the reinforcing base is attached to the bottom of the corrugated cardboard box body by adhesive.

[0008] Preferably, a connecting block is fixed to the top of the connecting strip, a connecting groove is provided on the top of the connecting block, a support strip is connected in the connecting groove, and a support plate is fixed to the top of the support strip.

[0009] Preferably, the bottom of the support plate abuts against the top of the corrugated cardboard box body.

[0010] Preferably, the outer wall of the connecting strip has a threaded hole that communicates with the connecting groove, and a threaded post is threadedly connected in the threaded hole. One end of the threaded post is fixed with a rotating shaft, and the other end of the threaded post is fixed with a fixing plate that abuts against the support strip.

[0011] Preferably, the reinforcing base is made of a moisture-proof material.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses glue to connect the reinforcing base to the bottom of the corrugated cardboard box body, which can reinforce the bottom of the corrugated cardboard box body. Furthermore, the bottom of the reinforcing base is connected to a cross-shaped base support, and a connecting strip is fixed on the outer wall of the cross-shaped base support. A connecting plate is fixed to one end of the connecting strip near the corrugated cardboard box body. The connecting plate is connected to the corrugated cardboard box body with glue. With the cooperation of the cross-shaped base support, connecting strip, and connecting plate, the reinforcing base can be reinforced, which indirectly further reinforces the bottom of the corrugated cardboard box body. Compared to existing designs, this invention strengthens the bottom of the corrugated cardboard box body to prevent cracking at the tape joints, thereby improving the sealing performance of the corrugated cardboard box body.

[0013] This utility model places the support bar into the connecting groove, and then rotates the shaft, which drives the threaded column to move in the threaded hole. After the fixing plate at one end of the threaded column abuts against the support bar, the support plate can be fixed to the top of the corrugated carton body. Under the action of the support bar and the support plate, the corrugated carton body can be supported, avoiding damage caused by excessive pressure on the corrugated carton body and improving the sealing performance of the corrugated carton body. Furthermore, the support plate can also reinforce the top of the corrugated cardboard box, preventing cracks at the tape joints on the top of the corrugated cardboard box and thus improving the sealing performance of the corrugated cardboard box. By rotating the shaft, the threaded column moves within the threaded hole. Once the fixing plate at one end of the threaded column is in contact with the support bar, the support plate can be disassembled, making it convenient to store items inside the corrugated cardboard box or to remove items from inside the corrugated cardboard box. This makes it quite convenient to use. Attached Figure Description
