Wine barrels are tools for holding wine and are generally divided into metal wine barrels and plastic wine barrels. The plastic wine cask has low cost and light weight, and has considerable advantages in moving and carrying, so the plastic wine cask is more and more widely applied in the current market. The wine bag is filled with wine liquid through the action of the distributor, the wine bag is guided through the guide pipe or the guide part to realize filling, and the wine bag filled with the liquid is distributed into various containers through the gas extrusion action from the distributor.

Generally, in order to fully utilize the volume of the container, the volume of the inner bag needs to be made larger, that is, the length and the width of the inner bag when the inner bag is laid flat are larger than the length and the width of the container, and a flow guide pipe with the length slightly smaller than the height of the container is arranged in the inner bag to help filling and flow guiding. And because the length of the inner bag is greater than the height of the container, after the inner bag with the flow guide pipe inside is placed into the container, the part of the bottom of the inner bag, which is greater than the height of the container, is bent to form a bent shape similar to an L shape. In the process of positive filling, wine liquid firstly reaches the bottom of the vertical part through the guide pipe, the wine liquid cannot be smoothly diffused into the transverse bending part due to the bending of the inner bag, and the bag body of the vertical part slightly expands and is pressed on the transverse bending part under the action of the gravity of the wine liquid along with the continuous filling of the wine liquid, so that the part is difficult to unfold, namely the transverse bending part cannot be filled with the wine liquid all the time, namely the inner bag is not unfolded sufficiently, so that the inner bag cannot be completely filled with the wine liquid. And along with filling the progress, the space of vertical part is used up or can't expand and continue to expand, and the wine liquid is constantly filled and is led to dragging to the connected position of vertical part and lance joint, easily pulls the inner bag and breaks. Sometimes, even if the bent portion is partially or completely unfolded, the vertical portion is still unfolded.

Therefore, an improvement in the prior art is disclosed in chinese patent application No. 201710735013.7, which discloses a liquid container, wherein a flow guide tube welded to a wine lance is provided in a bag, and the wine barrel is required to be filled upside down, i.e. the bottom of the barrel is arranged upward and the opening of the barrel is arranged downward. After the wine is filled in the inverted bag, the whole inner bag is also placed in the inverted bag, the top of the bag is arranged downwards, so that the liquid at the top of the bag enters the bag, is filled with the wine barrel under the action of gravity and is attached to the wine barrel, and is gradually unfolded from the top of the bag to the bottom of the bag, so that the bottom of the bag is not pressed or is bent to be difficult to unfold, and the bag is unfolded fully. However, in this manner, since the top of the bag is first filled with liquid, the top of the bag will engage the inner wall of the barrel under the force of gravity and block the vent at the neck of the barrel. Then, along with the continuous expansion of the inner bag, the gas between the wine barrel and the inner bag is gradually extruded to the bottom of the wine barrel, namely the upper part of the wine barrel during inverted wine filling, and cannot be discharged, so that a part for separating the wine barrel and the inner bag for exhausting needs to be additionally arranged between the inner bag and the wine barrel, namely a separation bag is additionally arranged, and a structure such as a convex part and the like capable of conveying the gas to the outside is arranged on the separation bag, so that the gas at the bottom of the wine barrel is smoothly discharged to realize the full utilization of the inner space of the container, and the arrangement can realize the full expansion of the inner bag but is complex and inconvenient. In addition, the material of the inner bag is improved in the prior art, so that the inner bag can not be broken under certain bearing capacity, can be fully unfolded without great force, and is relatively expensive in manufacturing cost.
