Next, a gas or particularly carbon dioxide gas is fed in the clearance between the inner face of boring pipe 7a and the outer face of the liquid discharging pipe 8a to discharge liquid B like beer or the like and recover it through the pipe 8a by the pressure.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for discharging a liquid filled with reveal or juice from cans such as beer cans and juice cans.

[Conventional technology]

Bottles are normally used as containers for beer, juice, seasonings, etc. For example, in the case of beer, a method is used at a beer factory to fill the bottle with a predetermined amount of beer and ship it. .

Beer bottles are automatically filled with a predetermined amount of beer, but immediately after the filling equipment starts operating, operating conditions are not stable, so the amount of beer filled into the bottle may not reach the predetermined amount. It may not be possible to reach it. on the other hand,
Beer bottles to be shipped must be filled with a specified amount of beer, and bottles filled with more than the specified amount or allowable amount cannot be shipped, and this is considered an incompletely filled bottle. .

The poorly filled bottles are removed from subsequent processes such as the filling process and the labeling process, sent to a recovery process, uncorked, and the beer inside the bottle is drained and recovered.

The present applicant has developed a method and device for discharging and collecting liquid, especially beer, from a bottle filled with liquid such as beer, and has published this in Japanese Patent Application No. 1184564 and Japanese Patent Application No.
184564 (both filed on July 19, 1999).

The above two inventions detect when the amount of beer filled in a beer bottle has not reached a specified amount, uncork the beer bottle, drain the beer, and collect the drained beer in a tank, The equipment that has implemented this has been operating extremely effectively.

However, the method and apparatus for recovering the liquid in the container are limited to recovering the liquid filled in the bottle, and cannot recover canned beer.

A method for recovering liquid from a can-shaped container, which comprises inserting the can-shaped container into the container and discharging the liquid in the can-shaped container by blowing air through a gap between the inner surface of the perforated pipe and the outer surface of the liquid drainage pipe. .

Furthermore, as a means for effectively carrying out the invention, there is provided a liquid recovery method for a can-like container, characterized in that a hole is made in the bottom of the can-like container, a plurality of perforated pipes are arranged in parallel, and each of the perforated pipes is inserted into the perforated pipe. 1. A can-shaped container for liquid, characterized in that the perforated pipes are constructed so that the perforated pipes move independently, and the plurality of liquid drainage pipes move in and out at the same time. It provides a collection method.

[For production]

The end of the can-shaped container, especially the bottom, is perforated with a perforated pipe, a draining pipe is inserted into the perforated pipe, and gas such as carbon dioxide is injected through the gap between the two pipes to fill the container through the draining pipe. Drain the liquid that was
It can be recovered.
