Problems solved by technology

[0002] After the existing metal barrel is manufactured, its inner cavity is directly used to fill the corresponding product. In the actual use process, the original product will inevitably remain on the inner wall of the metal barrel, which will cause the metal barrel to be filled again. Impurities or the same products of different qualities will be mixed in after the items, which makes the recycling rate of metal drums low, and the use cost of metal packaging drums is high

specific Embodiment

[0024] Specific examples, see figure 1 , the vertical inner ring 11 is provided with a sealing thread groove 112, and the outer ring surface of the plastic cover 10 is provided with a corresponding sealing thread 101, and the plastic cover 10 is sealed and connected to the sealing thread groove 112 through the sealing thread 101; The lower part of the buckle structure 12 is provided with a plugging inlet 121, and the upper part of the plugging inlet 121 is provided with a positioning cavity 122. The side convex roll seal 8 enters into the positioning cavity 122 along the plugging inlet 121 and is fixedly fastened. After the convex roll seal 8, it cannot be opened without being damaged by external force; the plastic mouth seat 9 and the flexible bag 4 are integrally structured, and they need to be replaced as a whole.

[0025] Its working principle is as follows: a flexible bag is arranged in the inner cavity of the metal barrel, which allows the loaded product to enter the inl...

Abstract

The invention provides an iron and plastic composite barrel. A metal packaging barrel is recycled conveniently and reliable, impurities of different qualities cannot be mixed into a product packaged next time, the purity of the product packaged into the metal packaging barrel every time is ensured, and the using cost of the metal packaging barrel is lowered. The barrel comprises a metal barrel body, a feeding inlet and a discharging outlet are formed in the metal barrel body, a flexible bag is arranged inside an inner cavity of the metal barrel body, a feeding inlet and a discharging outlet ofthe flexible bag extend to the position of the feeding inlet and the discharging outlet, an inner cavity of the metal barrel body is filled with the flexible bag in the expanded state, and the flexible bag is used for containing a corresponding product.

Description

technical field [0001] The invention relates to the technical field of packaging barrel structures, in particular to an iron-plastic composite barrel. Background technique [0002] After the existing metal barrel is manufactured, its inner cavity is directly used to fill the corresponding product. In the actual use process, the original product will inevitably remain on the inner wall of the metal barrel, which will cause the metal barrel to be filled again. Impurities or the same products of different qualities will be mixed in after the items, which makes the recycling rate of metal drums low, and the use cost of metal packaging drums is high. Contents of the invention [0003] In view of the above problems, the present invention provides an iron-plastic composite drum, which makes the reuse of metal packaging drums convenient and reliable, and does not cause impurities of different quality to be mixed into the reloaded products, ensuring that the metal packaging drums a...
