Bottom bearing lower opened type liquid and solid packaging bag

Abstract

The invention discloses a bottom bearing lower opened type liquid and solid packaging bag. A flexible bag body is included. The bag body is divided into an upper part and a lower part which are a bagmain body and a lower bearing part correspondingly. The upper end and the lower end of the bag body are opened. A loosening and tightening bundle port is sewn in the top edge position of the bag body,and an upper rope drawing hole is formed in the end portion of the loosening and tightening bundle port and internally provided with a top pull rope used for tightening the top of the bag body. A lower rope drawing hole is formed in the bottom edge of the bag body and internally provided with a lower pull rope used for tightening the bottom of the bag body. A plurality of inverted-U-shaped hoisting belts are evenly arranged on the periphery of the top end of the bag body, hoisting rings are formed at the upper ends of the hoisting belts, the lower ends of the hoisting belts downwards extend to the bottom of the bag body, and the parts, corresponding to the bag main body, of the hoisting belts are sewn on the bag main body. A bottom rope drawing structure is adopted in the packaging bag, unloading is conducted at the bottom of the bag body, the whole unloading process is simple and fast, and the unloading efficiency is high; and the U-shaped hoisting belts are used for assisting, the sealing firmness of the bottom of the bag body is improved, and the unloading work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of packaging bags, and more specifically relates to a bottom-supporting and bottom-opening liquid and solid packaging bag. Background technique [0002] As an important product of petrochemical industry, asphalt has been widely used in road and engineering construction and other fields. The annual output of asphalt in my country is about 25 million tons. Asphalt has two storage forms, liquid and solid. Due to the inherent characteristics of asphalt itself and storage Transportation requirements have special requirements for its packaging. For a long time, asphalt has been traditionally packaged in paper bags or iron drums. Iron drums generally cost more, occupy more space, and often need to be heated repeatedly during use. , the transportation cost increases, and leakage accidents cannot be avoided, and asphalt often adheres to the asphalt bucket, resulting in waste; while the asphalt packaging bags in the pri...

[0002] As an important product of petrochemical industry, asphalt has been widely used in road and engineering construction and other fields. The annual output of asphalt in my country is about 25 million tons. Asphalt has two storage forms, liquid and solid. Due to the inherent characteristics of asphalt itself and storage Transportation requirements have special requirements for its packaging. For a long time, asphalt has been traditionally packaged in paper bags or iron drums. Iron drums generally cost more, occupy more space, and often need to be heated repeatedly during use. , the transportation cost increases, and leakage accidents cannot be avoided, and asphalt often adheres to the asphalt bucket, resulting in waste; while the asphalt packaging bags in the prior art generally use the upper discharge port of the bag to discharge, which is not convenient for asphalt discharge. Reduce the efficiency of transportation operations

Therefore, the existing asphalt transport packaging mode is far from being able to meet the needs
