Simple valve-provided bottle cap for carbonated beverage

Abstract

Carbonated beverage already becomes beverage known by people, and the sale volume of various specifications of bottled carbonated beverage is very considerable; however, large-volume bottles are not suitable for all people, in particular to people with the poor physique or the old, and a user feels relatively strenuous when taking a heavy bottle and completing uncapping and pouring motion. In addition, gas contained in the carbonated beverage plays roles in keeping pressure inside a bottle and retaining freshness, however, the large-volume bottles often need to be repeatedly uncapped, then, the user can drink the beverage, gas loses are necessarily caused, and remaining beverage in the bottles are not fresh any more and even cannot be drunk. In order to overcome defects in the prior art, the invention provides a simple valve-provided bottle cap for the carbonated beverage. The bottle cap is characterized by comprising a movable plug with a self-returning function, a thin and long straw and an integrated bottle cap base body provided with a pressing button and connected with a disposable security part. The bottle cap is simple in structure, convenient to operate, beneficial to batch production and more suitable for large-range application and popularization compared with the prior art.

Description

technical field [0001] The patent of the invention relates to a bottle cap for carbonated beverages, in particular to a simple bottle cap with a valve for carbonated beverages. Background technique [0002] Carbonated drinks have become a well-known drink. Based on people's daily needs, the sales volume of carbonated drinks is still very large. Similarly, the sales volume of bottles used to hold carbonated drinks is also very large. There are many kinds of bottle specifications for carbonated beverages, ranging from 0.33 liters, 0.5 liters, 1 liter, 1.5 liters, 2 liters to 3 liters. However, bottles with larger capacities are not easy for everyone to operate, especially Young children and people with poor constitution or the elderly, pick up the heavier bottle and complete the action of unscrewing the bottle cap and pouring the drink and then still relatively strenuous. In addition, the carbon dioxide gas in the carbonated beverage plays a role in maintaining the pressure i...

Problems solved by technology

There are many kinds of bottle specifications for carbonated beverages, ranging from 0.33 liters, 0.5 liters, 1 liter, 1.5 liters, 2 liters to 3 liters. However, bottles with larger capacities are not easy for everyone to operate, especially For young children, people with poor physique or the elderly, it is still relatively difficult to pick up a relatively heavy bottle and then complete the actions of unscrewing the bottle cap and pouring the drink

In addition, the carbon dioxide gas in the carbonated beverage plays a role in maintaining the pressure in the bottle to keep the carbonated beverage in the bottle fresh. However, the bottle with a larger capacity often needs to open the bottle cap multiple times to drink the beverage in the bottle due to its larger capacity. Complete, this will cause the loss of carbon dioxide gas in the bottle, resulting in the remaining carbonated drinks in the bottle no longer fresh or even undrinkable

For the above problems, the industry has proposed some solutions, but their solutions are either too complicated, and the assembly links are more expensive, or the operation is troublesome, which is not conducive to use, or the volume is too large or the cost is too high, which is not conducive to mass production.
