An easy-twist bottle cap

Abstract

The invention discloses a novel easy-to-twist bottle cap. The novel easy-to-twist bottle cap comprises a bottle cap body, wherein a mounting groove is formed in the upper end of the bottle cap body, aheat conduction block is arranged on the inner bottom wall of the mounting groove in a penetrating mode, the lower end of the heat conduction block extends to the interior of the bottle cap body, theheat conduction block is fixedly connected with the bottle cap body in a sealed mode, a sealing plate is connected in the mounting groove in a threaded mode, and a heating mechanism is installed at the lower end of the sealing plate; and the heating mechanism comprises a fixing rod fixedly connected to the lower end face of the sealing plate, a friction plate is arranged in the mounting groove, the friction plate abuts against the heat conduction block, and a rotating sleeve sleeves the fixing rod. Through the friction of the fast rotating friction plate and the heat conduction block, the heat conduction block is rapidly heated, and the heat is transferred to the air in a bottle, so that the thermal expansion volume of the air is increased, and the pressure difference between the bottle and the outside of the bottle is reduced, and the bottle cap body can be screwed more easily.

Description

technical field [0001] The invention relates to the technical field of bottle caps, in particular to an easy-to-unscrew bottle cap. Background technique [0002] The bottle cap is a very common item in our daily life. The main function of the bottle cap is to realize the sealing of the drink in the bottle and prevent deterioration. Among them, the rotary bottle cap is the most common. The most common problem when using the existing bottle cap is The bottle cap can't be screwed, and the bottle cap can't be screwed, which is generally the result of negative pressure inside the bottle, and the negative pressure is usually caused by storing some hot liquid in the bottle and tightening the bottle cap, as the temperature of the liquid in the bottle drops , the volume of the hot air in the bottle shrinks due to the drop in temperature, and a certain degree of negative pressure is formed in the bottle, making it difficult to twist and open the bottle cap.
