Description

{BOTTLE CAP FOR STERILIZATION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bottle cap, and more particularly, to a bottle cap for UV sterilization which is detachably coupled to the spout of a bottle container to UV sterilize the liquid contained in the bottle container.

Liquid beverage products in which drinking water, beverages, or other liquid contents (i.e., liquid contents) are packaged in bottle containers are being produced and sold. This liquid beverage product is opened by the consumer with the lid. After the lid is opened, the contents of the liquid contained in the container may be all consumed by the consumer. However, there are many cases where the lid of the container of the bottle is stored with the lid. Once the bottle container is opened, even if the lid of the bottle container is closed with the lid, there is a high possibility that the microorganisms including various bacteria propagate in the liquid contents in the bottle container. Particularly, the vicinity of the mouth of the bottle container is likely to cause a multiplication of bacteria.

On the other hand, there has been proposed a technique of UV sterilizing liquid content in a bottle container using a UV lamp disposed outside the bottle container. However, this technique can only be used for bottle containers made of materials that are far away from the liquid in the bottle and UV lamps and are capable of transmitting UV. In addition, even if the bottle container is made of a material allowing UV transmission, most of the bottle containers currently used are not highly transparent to UV, so that the utility of the technology is not realistic.

WO 2002/38447 (May 16, 2002).

On the other hand, if a UV light source is installed on the bottle cap coupled with the bottle container, the problem of the bottle container acting as a UV blocking wall can be solved. However, since the UV propagation distance between the UV light source installed on the bottle cap and the surface of the liquid contained in the bottle container is long, there is a limit to increase the sterilization efficiency of the liquid contained in the bottle container. Further, this technique has a limitation in that the lower the liquid level contained in the bottle container, the lower the UV sterilizing effect of the UV light source liquid. In addition, although the bottle container is generally susceptible to contamination, the bottle container is required to be more strongly sterilized, but it has been difficult to reliably sterilize the bottle portion of the bottle by conventional techniques.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a UV light transmitting member that includes a UV LED and a UV transmitting member that transmits UV from the UV LED, wherein when the bottle container is disposed such that the spout of the bottle container faces downward, The present invention provides a bottle cap for UV sterilization that can minimize the UV transmission distance to the liquid to be sterilized by directly contacting the liquid in the container.
