[0002]

2. Description of the Related Art In general, a bottle washing machine has a carrier in which a large number of bottle holders are attached to an endless chain that is wound around a can body through a large number of sprockets, and a bottle holder in each carrier. A bottle supply section that supplies bottles, a jet cleaning section that sprays cleaning liquid onto a large number of bottles carried by a carrier, and a cleaning area that includes a dip tank that cleans by dipping these bottles, and this cleaning The bottle is provided with a bottle bottle that has been washed in the area and is taken out from the bottle holder of the carrier and discharged.

In particular, a single-ended container is provided with a bottle supply portion for supplying a bottle into each bottle holder of an endless carrier and a discharge bottle portion for taking out the bottle from the holder on the same end side of the can body. In the type of bottle washing machine, the bottle discharge part is located directly above the bottle supply part, and the bottle that has been delivered from outside is placed in the cleaning area below the position where the bottle is supplied to the carrier of the bottle supply part. A pre-immersion tank is provided to carry out pre-cleaning before carrying in, and above this pre-immersion tank, the inside of the can body and the end side where the above-mentioned bottle and bottle parts are arranged are cleaned. A partition for partitioning the region is provided (see Japanese Patent Publication No. 2-41965).

[0004]

Since the bottle before cleaning is carried in from the outside to the bottle feeding portion, the atmosphere on the bottle feeding side may be contaminated. Moreover, since the preliminary cleaning tank is provided below the bottle supply section, the vapor flowing from the preliminary cleaning tank causes the atmosphere on the bottle supply side to enter the upper bottle side. On the other hand, since the bottle discharge portion is a portion for discharging a clean bottle after washing, a clean atmosphere must be maintained. Therefore, it is preferable that the atmosphere on the side of the bottle portion and the atmosphere on the side of the bottle portion are completely cut off.
However, in the single-end type bottle washing machine as described above, the endless carrier is continuously hung between the bottle feeding section, the washing area having the jet washing section, the dipping tank and the like and the bottle discharge section. Therefore, it was impossible to completely shut off the bottle feeding part and the bottle discharging part by a partition or the like.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and prevents the atmosphere on the side of the bottle, the steam or the outside air from the preliminary dipping tank from entering the inside of the bottle, and It is an object of the present invention to provide a single-end type bottle washing machine capable of maintaining a clean atmosphere.

[0006]
