Liquid container

Abstract

The invention provides a liquid container and belongs to the technical field of machinery. The problem of low filling volume of an existing liquid container is solved. The liquid container which is ofan improved structure comprises a bucket-shaped shell, a flexible inner bag which is arranged in the shell and used for storing liquid and a liquid outlet valve which controls flow-in and flow-out ofliquid in the inner bag, the inner bag is fixedly connected with the liquid outlet valve, a bag opening of the inner bag and the liquid outlet valve form seal, and the shell and the liquid outlet valve form seal; one end of the liquid outlet valve is connected to the shell, a ventilation structure which can control gas to enter and leave from the shell is further connected to the shell, and a separation bag is further arranged between the inner bag and the shell in a sleeving mode; the separation bag is a flexible bag, a plurality of protrusion portions which protrude out of the surface of the separation bag are arranged on the separation bag, each protrusion portion extends in the direction away from the bag opening of the separation bag from the bag opening of the separation bag, a first auxiliary air channel which is used for air circulation is formed between two adjacent protrusion portions, and the first auxiliary air channel can always be communicated with the ventilation structure. The filling volume of the liquid container which is of an improved structure is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a container, in particular to a liquid container. Background technique [0002] There are many kinds of liquid containers on the market, such as a wine barrel, which is a tool for holding wine. Generally, there is a wine spear at the mouth of the barrel, and the wine spear cooperates with the dispenser to realize the wine barrel Squeeze out the alcohol inside. At present, the barrels commonly used in the market are hard metal barrels. The hard metal wine barrel can resist the high pressure generated by the internal gas and provide enough strength to ensure that it will not be burst. However, this kind of metal wine barrel is costly and troublesome to clean. Generally, merchants do not have special equipment for cleaning metal wine barrels. Therefore, after the wine in the barrel is used up, the empty barrel needs to be transported to the manufacturer for cleaning. , thus incre...

Problems solved by technology

However, if the exhaust has a certain hardness, although the exhaust structure can maintain its original shape and extend to the middle or bottom of the outer barrel smoothly after inverting the entire liquid container, but when the inner bag is continuously filled with liquid and opened, it should have hardness. If the exhaust is too soft, it will be easily affected by gravity or the inner bag will be stretched when the liquid is poured upside down. During the process, it is folded or tilted due to the friction and extrusion of the inner bag, so that the exhaust structure is still accumulated on the neck of the outer barrel, and the gas at the bottom is still not discharged, and the bottom space that can store liquid is still wasted

Therefore, it is still impossible to effectively improve the filling capacity of the liquid container in the prior art.
