Snap-on assembly for secure connection of closed bucket and liner bag

Abstract

The invention discloses a padlock type assembly capable of making a closed barrel and a lining bag stably connected. The padlock type assembly comprises a connecting piece, a connecting piece seal ring, a lock ring, a support, a barrel plug, a barrel plug seal ring, an outer seal cover and a lock piece. The lock ring is arranged on the outer side of a connecting piece outer overturned edge and isof a rigidity body structure, and the connecting piece is locked through cooperation of the lock ring, the lock piece and a telescopic groove. The telescopic groove corresponds to a protruding ridge and the lock piece. An annular clamp groove is formed in the connecting piece outer overturned edge, and the outer seal cover can be buckled to the connecting piece. The padlock type assembly has the advantages of being simple and novel in structure, suitable for reliable connection of multiple closed barrels and lining bags and very convenient to mount and dismount.

Description

technical field [0001] The invention relates to a connection technology of a closed barrel and a liner bag in the field of packaging technology, in particular to a buckle-lock assembly capable of stably connecting the closed barrel and the liner bag. Background technique [0002] At present, liquid chemical products usually use closed barrels as packaging containers, and these packaging containers usually need to be disposed of as hazardous waste after one use. With the environmental protection requirements increasing year by year, the cost of hazardous chemical waste disposal is getting higher and higher. , the pressure on environmental protection is also increasing, and the cost of use is getting higher and higher. [0003] Existing solutions: 1. Design a plastic part at the mouth of the inner lining bag to be directly buckled on the closed barrel. This solution is simple and practical, and can solve the packaging requirements of some liquid chemicals. When subjected to la...

Problems solved by technology

[0003] Existing solutions: 1. Design a plastic part at the mouth of the inner lining bag to be directly buckled on the closed barrel. This solution is simple and practical, and can solve the packaging requirements of some liquid chemicals. When subjected to large internal or external forces, The plastic parts are easy to get out of the barrel mouth, which is difficult to meet the requirements of dangerous goods packaging, and the actual application range is limited; 2. An interface piece consisting of a nut and a bung is designed at the mouth of the inner lining bag, and the inner lining bag and the nut piece Although this solution can form a firm combination with the mouth of the barrel and meet the packaging requirements of hazardous chemicals, it has the disadvantage of being difficult to locate during installation
