Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a method for discharging a filled liquid such as beer or juice from cans such as beer cans and juice cans.

[Conventional technology]

Bottles are used as containers for ordinary beer, juice, or seasonings. For example, in the case of beer, a method of filling a predetermined amount of beer into the bottle and shipping it in a beer factory is adopted. .

In the beer bottle, a predetermined amount of beer is filled into the bottle by automatic filling, but immediately after the operation of the filling device is started, since the operating conditions are not stable, the amount of beer filled in the bottle is reduced to the predetermined amount. May not be reached. On the other hand, beer bottles to be shipped must be filled with the specified amount of beer in the bottle note, and those filled with an amount other than the specified amount or the permitted amount cannot be shipped. Becomes

A method is adopted in which the poorly filled bottle is removed from subsequent steps such as a filling step and a label applying step, sent to a collecting step, and unplugged, and the beer inside the bin is discharged and collected.

The present applicant has developed a method and an apparatus for discharging and recovering liquid, especially beer, from a bottle filled with liquid such as beer, and has developed this method.
