BEVERAGE BOTTLE ATTACHMENT AND BEVERAGE BOTTLE USING SAME

摘要

Disclosed is a simply-structured beverage bottle attachment with a two-stage screw head and a filter cylinder coaxially coupled to the screw head; also disclosed is a beverage bottle using the same. Tea leaves (T) are placed in a plastic bottle and a lower female screw portion on the two-stage screw head of the attachment is screwed into a male screw portion of the plastic bottle. When the plastic bottle is tilted, the tea in the plastic bottle passes through through-holes and flows out of a cylindrical section which forms an opening. The tea grounds in the plastic bottle are captured by the filter tube and prevented from flowing out.
