Problems solved by technology

[0004] However, most of the bottom sealing structures of the existing transport cartons are composed of four square plates, and tapes and other items are used for bonding and sealing. This sealing method is not fast enough to carry heavy items. At the same time, the bottom seal is easily opened by gravity, causing the items inside the carton to be spilled, causing damage to the items. In order to ensure the use of the carton, it is necessary to stick multiple layers of tape on the bottom, which is not conducive to the recycling of the carton. Affect its next use and increase input cost

Embodiment 1

[0059] see Figure 1-12 , a carrying carton with a self-weight locking and sealing structure at the bottom, including a carton body 1, the carton body 1 includes a box body 2, a gravity self-locking floor assembly 3 is connected to the lower end of the box body 2, and the gravity self-locking floor assembly 3 includes a narrow The side bottom plate 301, the narrow side bottom plate 301 is fixedly connected to the front and rear ends of the box body 2, the wide side bottom plate 303 located at the lower side of the narrow side bottom plate 301 is fixedly connected to the left and right ends of the box body 2, and the two wide side bottom plates 303 are close to each other One end is fixedly connected with a gravity self-locking plate 304 , and a self-locking plate hole 302 matching the gravity self-locking plate 304 is opened on the narrow side bottom plate 301 . Through the mutual cooperation of the narrow side bottom plate 301, the wide side bottom plate 303 and the gravity s...

Embodiment 2

[0069] see Figure 1-12 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 2 and embodiment 1 is: please refer to Figure 11 , the processing technology of carton body 1 is the following steps:

[0070] M1. Preliminary bonding: use the No. 1 dispensing equipment to bond the honeycomb reinforcement board 102 on both ends of the corrugated buffer board 103, and dry and fix it;

[0071] M2. Re-bonding: Use No. 2 glue dispensing equipment to bond the plastic moisture-proof board 101 on the outer end surface of the honeycomb reinforced board 102, and perform pressing, drying and fixing;

[0072] M3. Board making: according to the size of the customized carton body 1, use cutting equipment to cut out the composite board for making the carton body 1;

[0073] M4. Detail...

Embodiment 3

[0076] see Figure 1-12 , where the same or corresponding components as those in Embodiment 1 use the corresponding reference numerals as in Embodiment 1, and for the sake of simplicity, only the differences from Embodiment 1 will be described below. The difference between this embodiment 3 and embodiment 1 is: please refer to Figure 7-10 with Figure 12 , the method of using the gravity self-locking floor assembly 3 is as follows:

[0077] S1. Fold the two narrow bottom plates 301 toward the box body 2 to cover the lower end of the box body 2;

[0078] S2. Then insert the gravity self-locking plate 304 into the hole 302 of the self-locking plate, and drive the wide-side bottom plate 303 to fold toward the box body 2 until the gravity self-locking plate 304 completely enters the box body 2;

[0079] S3. Use your hands to press the wide-side bottom plate 303, so that the wide-side bottom plate 303, the narrow-side bottom plate 301 and the box body 2 are fastened;

Abstract

The invention discloses a carrying carton with a bottom self-weight locking and sealing structure, and belongs to the field of cartons. The carrying carton with the bottom self-weight locking and sealing structure comprises a carton body, wherein the carton body comprises a box body, the lower end of the box body is connected to a gravity self-locking bottom plate assembly, the gravity self-locking bottom plate assembly comprises narrow-edge bottom plates, the narrow-edge bottom plates are fixedly connected to the front end and the rear end of the box body, the narrow-edge bottom plates, wide-edge bottom plates and gravity self-locking plates can matched one another, so when objects are placed in the box body, the narrow-edge bottom plates, the wide-edge bottom plates and the gravity self-locking plates can be locked with one another through self weights of the objects, an adhesive tape is effectively omitted, the fastening performance of the bottom of the carton body is improved, the phenomenon that the bottom of the carton body is exposed due to the fact that objects are too heavy is effectively avoided, the objects are effectively protected, the breakage rate of the carton body is effectively reduced, the repeated utilization rate of the carton body is improved, and the input cost is reduced.

Description

technical field [0001] The invention relates to the field of cartons, in particular to a transport carton with a self-weight locking and sealing structure at the bottom. Background technique [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. Cartons are commonly used with three layers and five layers, and seven layers are rarely used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The color and feel are different, and the paper (color, feel) produced by different manufacturers is also different. [0003] With the increasing competition in modern society, people move more and more with the change of work and mood, and moving companies are also constantly rising. When moving companies provide customers with moving services, they need to use a large number of moving cartons to store custome...
