The cooperation of multiple flexible structural layers can not only minimize the waste of solid materials, but also effectively avoid the influence of odor on operators, and at the same time, it can also effectively avoid the introduction of external foreign matter to cause pollution to the material. Considering the sealing effect and softness requirements, the thickness of each flexible structural layer of the utility model is preferably 0.05-0.15mm; more preferably, the thickness of the inner flexible structural layer is 0.05-0.15mm, and the thickness of the outer flexible structural layer is 0.15-0.25mm.

The material of the outer flexible structural layer is selected from one of thermoplastic polyurethane elastomer material, low-density polyethylene material or high-density polyethylene material.

[0029] In a specific embodiment, the feeding port is configured as a chuck-type interface, and the feeding port is configured as a chuck-type interface. It is understandable that the chuck-type interface of the utility model can not only realize the sealed connection between the feeder and the equipment to be fed, ensuring that the material does not leak and the odor does not spread, but also facilitates more convenient disassembly after the feeding is completed.
