Abstract
A barrel of a flashlight has a front barrel portion defining a front receiving space, and a rear barrel portion connected to the front barrel portion and defining a rear receiving space for receiving a battery unit. A lamp is disposed in a reflector retained in the front receiving space of the front barrel portion. A conductor unit is disposed in the barrel and establishes electrical connection between the lamp and the battery unit. A coupling sleeve has a front coupling section formed with an internally threaded surface for engaging an externally threaded mouth of a light-transmissible bottle body of a plastic beverage bottle, a rear coupling section mounted securely on the front barrel portion, and an intermediate section interconnecting the front and rear coupling sections. A lens piece is mounted in the intermediate section of the coupling sleeve.
