Sleeve joint part 1 is round tubular, and is sleeved on the inlet pipe 4 on the upper end of ton barrel 3. As shown in Figures 3-5As shown, both ends of the sleeve 1 are provided with raised reinforcing rings 5 ​​to improve the strength of the sleeve 1 and prevent the sleeve 1 from tearing due to deformation when it is connected to the inlet pipe 4 by tension. The blocking part 2 is flared, and its cross-sectional area increases in the direction away from the sleeve 1. In this embodiment, the blocking part 2 is a conical tube.

[0031] like Figure 6 and Figure 7 As shown, the installation steps of this utility model are as follows: 1. With the blocking part 2 facing down, insert the flat opening into the ton 3 from the inlet pipe 4; 2. Pull out the sleeve part 1 and make it higher than the inlet pipe 4; 3. Flip the sleeve part 1 outward to form a U-shape with the opening facing down, and sleeve it on the inlet pipe 4 from top to bottom.

[0032] like Figure 8 As shown, when the inner liner bag is filled with liquid material, the blocking part 2 is pulled upwards out of the ton 3, so that it unfolds into a cone shape with the opening facing upwards, forming a funnel shape, which is used to block the splashing liquid, so that the splashing liquid will only adhere to the inner wall of the blocking part 2 and will not fly out of the blocking part 2.

[0033] like Figure 9 As shown, after the liquid material in the inner liner bag is filled, the blocking part 2 is rolled up along its axial direction and placed inside the ton container 3, so that when the material in the inner liner bag shakes, it only comes into contact with the flat opening. The diameter of the rolled blocking part 2 is smaller than the distance between the upper inner wall of the ton container 3 and the liquid surface inside the inner liner bag. With this configuration, the blocking part 2 is subjected to pressure from both the upper inner wall of the ton container 3 and the liquid surface, causing the rolled blocking part 2 to deform, thus making its structure more stable.

[0034] The beneficial effects of this utility model are: when liquid materials splash during filling and when the material shakes during transportation after filling, they will only come into contact with the flat opening. When the material inside the ton container 3 needs to be replaced, a new inner liner bag and flat opening can be replaced. The rubber ring and the lid can be reused.

First, the blocking part 2 is inserted downwards into the ton container 3. Then, the sleeve part 1 is pulled out from the inlet pipe 4 and flipped outwards to form a U-shape with the opening facing downwards, fitting the inlet pipe 4 from top to bottom. A radially T-shaped inner plug 6 is inserted into the inlet pipe, its upper end abutting against the upper end of the inlet pipe 4, and the sleeve part 1 is clamped between the inner plug 6 and the inlet pipe 4 through an interference fit. An inlet flange 7 is threadedly connected to the inlet pipe 4. An inwardly extending pressure ring is provided at the upper end of the inlet flange 7, and the upper end of the inner plug 6 is clamped between the lower end of the pressure ring and the upper end of the inlet pipe 4. A lid 8 covers the inlet flange 7 through a threaded connection, sealing the inlet flange 7. This configuration not only facilitates the installation and removal of the flat opening but also allows for fast installation and removal with high efficiency.
