CONTAINER CAPABLE OF LIMITING QUANTITY OF CONTENTS REMOVED THEREFROM AND METHOD FOR REMOVING SAME

摘要

Disclosed are a container capable of limiting the quantity of contents removed therefrom and a method for removing same. The container includes a main body portion (101), a pressurizing portion (104) and an outflow channel (105), wherein the main body 5 portion (101) includes a space (102) for holding the contents and a space for gas (103), the pressurizing portion (104) is a device for increasing the gas pressure in the space for gas(103), and the outflow channel (105) is a device in communication with the space (102) for holding the contents so as to allow the outflow of the contents; it also includes a moving component in the outflow channel (105) movable with the contents to be taken out, and a 10 gas channel outlet moving with said moving component; on the movement track of the gas channel outlet there is an opening communicating with ambient air and in communication with the gas channel outlet; the other end of the gas channel (106) opens in the space for gas in the main body portion. By means of the container and the removal method therefor, the removal of a limited quantity or a determined quantity can be achieved so that the 15 contents removed therefrom each time will be no more than or even equal to a set value, thus improving peoples scientific living standard.
