Disposable beer aseptic packaging bag and filling method

Abstract

The invention discloses a disposable beer aseptic packaging bag. The bag comprises a bag body, a beer filling opening, a lower cover and a beer outlet pipe assembly; the beer filling opening is formed in the bag body, beer can be injected or discharged in the bag body through the beer filling opening, the lower cover is arranged on the beer filling opening and used for connecting and sealing the beer filling opening, the beer outlet pipe assembly comprises a beer outlet pipe and a cover, one end of the beer outlet pipe is connected with the lower cover and communicates with the bag body, the other end of the beer outlet pipe is sealed by the cover, and the beer outlet pipe is an elastic hose, and the elastic hose is pressed or opened to be used for opening or closing a beer outlet passage of the beer outlet pipe. The invention further discloses a filling method of the disposable beer aseptic packaging bag. The beer packaging bag is low in packaging cost, due to the fact that in the drinking process, no air is contained in the packaging bag, remaining beer in the packaging bag is never in contact with the air, long-time storage is achieved, and the freshness retaining time is long.

Description

technical field [0001] The invention relates to the field of beer packaging, in particular to a disposable beer aseptic packaging bag and a filling method. Background technique [0002] How to enjoy a glass of fresh draft beer at any time is the pursuit of beer lovers, but the shelf life of draft beer is relatively short. At present, most of the existing beer is packaged in glass bottles and cans. After the container is opened, the beer is in contact with the air, and the preservation time is only a few hours. After a period of time, the fresh taste of draft beer will be completely lost. . Due to the high pressure of beer, fresh draft beer is packaged in stainless steel or PET barrels, etc., which need to be equipped with complex packaging machinery, wine sales and refrigeration equipment. The structure is complex, the cost is high, and it is not conducive to transportation. [0003] In order to solve the above problems, a variety of flexible packaging bags that can withst...

AI Technical Summary

Problems solved by technology

However, in order to withstand the pressure of the pressurized beverage such as beer, the beer packaging bag in this technical solution is made of multi-layer composite film materials. This material has high strength and is difficult to be pierced by the wine outlet pipe. It is convenient to insert the wine outlet pipe. In this technical solution, the beer in the bag is sealed by the gas nozzle or the sealing film, but the gas nozzle and the sealing film have poor pressure resistance. The bagged beer with these two structures is prone to leakage during transportation. The loss rate is high, resulting in increased production costs; and the use of a separate wine outlet pipe and bag, the structure is complex, and the difficulty of use increases
