Container capable of limiting quantity of contents removed therefrom and method for removing same

摘要

A container capable of dispensing a quantity of contents less than or equal to a set value. The container includes a main body portion, a pressurizing portion and an outflow channel, wherein the main body portion includes a space for holding the contents and a space for gas, the pressurizing portion increases the gas pressure in the space for gas, and the outflow channel communicates with the space for holding the contents to allow the outflow of the contents; it also includes a moving component in the outflow channel movable with the contents to be taken out, and a 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 opens in the space for gas in the main body portion.

主权项

1. A method for limiting the quantity of contents removed from a container, comprising:
A: according to a volume of contents required to be removed, determining a distance, by which a gas outlet in communication with a gas for pressurizing is required to move, from start of movement to being in communication with an ambient gas; B: using the gas to increase a pressure in a container holding the contents, and pushing the contents to move towards an outlet channel of the container; C: the contents in movement driving a moving component in the outlet channel of the container to move along; D: the gas outlet in communication with the gas for pressurizing moving along with the moving component; and E: when the gas outlet moves to be in communication with the gas outside the container, the pressure in the container decreasing, and the contents stopping moving outwards, so that the removal process of the contents ends.
