Title:
貯蔵寿命試験ユニット
Document Type and Number:
Japanese Patent JP2004513333
Kind Code:
A
Abstract:
A testing apparatus for testing the level of retained gas at elevated pressure in plastic containers for carbonated beverages includes a manifold assembly for engaging the mouth of a test set of the containers. The apparatus additionally includes a gas supply for supplying a desired quantity of a selected gas to each container, the gas preferably helium. The apparatus further includes pressure measuring units for measuring the pressure in each container, and a data collection system coupled to the pressure measuring units for periodically collecting pressure data along with ambient temperature data as a function of time. The collected data can be analyzed to determine shelf life of the containers. Using helium, the shelf life determination can be accomplished in about 1/7th the time of conventional shelf life tests.
