Description

[0001] Washing device for bottles [

The present invention relates to an apparatus for cleaning a bottle-type container.

In general, a bootle type container is a container for storing liquid or powder, and has a narrow neck and container inlet. A container is provided with a cap at the inlet of the container to store various products such as drinks, cosmetics, . Hereinafter, the bottle type having a narrow neck and neck opening as described above will be referred to as a " container ".

Generally, it is essential to prepare a liquid product and wash the inside of the container before putting it in the container. Therefore, the product production line is provided with a separate container cleaning device and is subjected to a washing process.

Conventionally, in order to clean the container, washing water is injected into the container to clean the container, high-pressure air is injected, or the container is evacuated to remove foreign substances inside the container. Further, in order to facilitate removal of foreign substances in the container, a method of generating washing water or high-pressure air or vacuum after turning over the container is used.

Thus, in the conventional container washing apparatus, a large amount of washing water is required to use the washing water, and a facility for treating the washing water used and the washing water used is required. In addition, the pneumatic discharging method or the vacuum suction method is also required to generate a large amount of pneumatic or vacuum Additional facilities are required.

As described above, the conventional container cleaning apparatus requires a separate cleaning facility for cleaning the container in the product production line, and it is difficult to improve the productivity due to the waiting time for cleaning the container.
