Drinking bottled water is popular with most people. From observing found that the bottle caps of drinking water has a little catching area and slippery skin. So、 the opening of the bottle with use the exertion of squeezing the bottle caps directly、 it must to great exertion、 which is a problem for child、 woman、 the elderly and everybody who have less strength of the wrist、 because it must use two forces : the force of hand squeeze to increase the friction between the hands and the bottle cap、 and torque or rotation to open the bottle caps. Have a research was published from Japan through www.catdumb.com about why Japanese women cant open their bottled drinking-water. Because the opening of the bottle caps requires the force of hand squeeze 12-45 kgF. If the bottle caps of drinking water has slipperiness at medium level、 which it has the coefficient of friction is 0.5、 so it requires the force of hand squeeze 20 kgF. But the people generally have the average force of hand squeeze is 10 kgF、 so cant open the bottle cap. In addition、 encountered problems with collecting tube sucked by let it fall into a water bottle or folding them and clamping them on the bottle caps、 causes damage to the tube、 dirt or contact with external germs、 affecting the health of the consumer. This is a starting point to create named device "The drinking bottle opener"、 designed to have the handle for a force-saving according to the principle of torque. Moreover、 the device is small、 easy to carry、 ready for use anywhere、 has the tube sucked holder and has a cover lid for reduces the risk and protects the tube from damage、 dirt and contact with external germs. So that safe using device and consuming water bottled.
