Description

Technical Field

[0001] The utility model relates to the technical field of cartons, and more specifically to a carton capable of preventing water seepage from the bottom. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the paper produced by different manufacturers (color, feel) is also different.

[0003] In order to facilitate sealing at both ends during carton processing, four pieces of cardboard are usually set at the two ends of the carton to seal the box body with creases. Generally, no other processing operations are performed after sealing. When the carton is placed on the ground, if the ground is wet or has moisture, the bottom of the carton will absorb water, causing water to penetrate from the bottom of the carton into the interior of the carton, affecting the items placed inside the carton. In addition, the hardness of the carton decreases after it becomes wet, and it is also prone to damage. Therefore, it is necessary to design a carton structure that solves the problem of water seepage at the bottom of the carton. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a carton which can prevent water seepage from the bottom.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a carton that prevents bottom water seepage, comprising a carton main body, a carton sealing piece is arranged at the top edge of the carton main body, a waterproof oil paper is arranged on the bottom lower surface of the carton main body, and a storage cavity is arranged inside the carton main body, a reinforcing gasket is installed at the bottom of the storage cavity, a groove is arranged on the top of the reinforcing gasket, a buffer layer is installed inside the groove, and a corrugated paper layer is placed above the buffer layer.

[0006] As a further improvement of the technical solution of the utility model, there are four carton sealing pieces in total, and a fold for rotation is provided between each carton sealing piece and the carton body.

[0007] As a further improvement of the technical solution of the utility model, the waterproof oil paper is specifically a component made of silicone oil paper, and the upper surface of the waterproof oil paper is fixed to the lower surface of the carton body by glue.

[0008] As a further improvement of the technical solution of the utility model, the reinforcing gasket is a component made of a foam board material as a whole, and the cross-sectional length and width of the reinforcing gasket are respectively smaller than the cross-sectional length and width of the storage cavity.

[0009] As a further improvement of the technical solution of the utility model, the cross-sectional length and width of the buffer layer are respectively smaller than the cross-sectional length and width of the groove.

[0010] As a further improvement of the technical solution of the utility model, the buffer layer includes a protective edge attached to the edge of the inner wall of the groove, and a plurality of honeycomb paperboards are evenly arranged inside the protective edge.

[0011] Beneficial effects of the utility model:

[0012] The utility model arranges waterproof oil paper made of silicone oil paper at the bottom of the carton body to enhance the waterproof performance, prevent water seepage from the bottom, and protect internal items from being affected by moisture. The arranged reinforcing gasket can improve the carrying capacity of the carton and protect the internal items. The reinforcing gasket is made of foam board material to prevent further waterproofing when the waterproof oil paper is severely worn and the waterproof ability is weakened. The top of the reinforcing gasket is designed with a groove, and a buffer layer and a corrugated paper layer are installed in the groove to provide additional buffering protection. The multi-layer structure design can effectively prevent water from seeping into the carton to affect the storage of items, and also reduce the problem of damage to the carton caused by moisture.
