Beverage bottle cap with self-cooling device and beverage bottle thereof

Abstract

The invention discloses a beverage bottle cap with self-cooling device and a beverage bottle thereof, wherein the beverage bottle cap comprises an annular cover body, a top cover and a self-cooling device; the top cover is provided with a ventilation hole I, a ventilation hole II and a straw hole which penetrate through the top surface of the top cover; the self-cooling device comprises a fan-shaped sealing plate, a three-way control valve, a refrigerant storage container, a refrigerant output pipe and an elastic suction pipe. The beverage bottle cap with the self-cooling device adopts the waythat the control valve core of the three-way control valve is driven by the rotary fan-shaped sealing plate, in the state of self-cooling, on the one hand the beverage bottle body can achieve internal and external connection through the ventilation hole I, and on the other hand the bottom of the liquid level of the beverage entering the beverage bottle body can be heat-absorbed and vaporized, andthe temperature of the beverage is reduced; in the state of drinking, on the one hand the beverage bottle body can achieve internal and external connection through the ventilation hole II, and on theother hand directly drinking can be achieved without opening the bottle cap, resolving the problem that the refrigerant accelerates to evaporate, which is particularly suitable for containing the antipyretic beverage in summer.

Description

technical field [0001] The invention relates to a beverage bottle cap and a beverage bottle thereof, in particular to a beverage bottle cap and a beverage bottle with a self-cooling device capable of realizing beverage self-cooling function, and belongs to the technical field of liquid packaging. Background technique [0002] Cold drinks are people's first-selected antipyretic drinks in summer. Drinks are usually placed in refrigerators or freezers for refrigeration, but cold drinks cannot be enjoyed in places without refrigeration conditions such as the wild. Although the existing beverages mostly adopt the method of encapsulating the pressurized gas together with the beverage and adding it to the beverage bottle, that is, the pressurized gas vaporizes and releases the heat during the drinker's drinking process, but opening the beverage bottle in an environment with high external temperature usually The pressurized gas in the beverage will quickly overflow, on the one hand,...

AI Technical Summary

Problems solved by technology

Beverage bottles with this structure also have the problem of opening the bottle cap for drinking and accelerating the vaporization speed of the refrigerant in a completely open way, and the installation of the pipeline penetrating into the bottle body is more complicated, and there is a risk of beverage leakage
