Background technology
Usually, when beverage need in the container liquid with as additive or auxiliary element, during such as carbon dioxide, vitamin powder or the like particulate or concentrated liquid mixing, the chamber that separates that vessel is useful on the storage auxiliary element is necessary.
The U.S. Patent number of comprising No.937 is arranged, and a lot of suggestions above 5,000 kinds of 049 (application on October 19th, 1909) are about being used for mixing at container the structure of two or more compositions.
Yet disclosed container in above-mentioned patent does not obtain business success owing to, processing technology low such as efficient, inconvenience use or the like problem.
Easier operation for lid arrangement has further needs, also need a kind of container, described container is used for mixing a kind of or more kinds of composition in the composition that is contained in container, does not produce the problem that bend pipe damages and change structure or implemented undue strength owing to opening eduction gear for use.
Recently, on January 17th, 2002 was advised other structure at the PCT/EP2002/004523 of Japanese publication and the Japanese patent application No. No.2001-00185428 of application on July 19 calendar year 2001, and still, it does not obtain business success.
Particularly, problem is arranged, promptly fall into container, and child may swallow it from discharging a slice that port cuts off in the structure of above-mentioned Japanese Patent Application Publication.In order to overcome this problem, can not be developed from the eduction gear that the new neck of container separates, still, this eduction gear can not be used traditional neck of container.
And, have the eduction gear at the neck place that remains on container, in described container, have pressure, when removing, the pressure in the container is opened.Yet this eduction gear can not use the container place that is not exerting pressure.
Equally, a kind of percussion mechanism is arranged, it is applicable to by shaking and disconnects diaphragm seal to use, enter container thereby discharge auxiliary element from storage chamber, but problem is that described percussion mechanism may be opened storage chamber owing to unexpected little impact.
In order to prevent that accident from opening storage chamber, described percussion mechanism should firmly assemble.Yet in this case, another problem has produced, and promptly the weight of percussion mechanism increases.
