Document Type and Number:
WIPO Patent Application WO/2022/244648
Kind Code:
A1
Abstract:
[Problem] To provide a device for measuring the gas concentration in a packaging bag and a method for measuring the gas concentration in a packaging bag with which: it is no longer necessary to move, for every packaging bag to be measured, the tip part of a laser emission unit and the tip part of a laser reception unit by means of a reciprocating motion mechanism towards the obverse and reverse surfaces of the packaging bag, making it possible to reduce the packaging time; and it is possible to measure the gas concentration of the packaging bag without being influenced by the thickness of the packaging bag, without the need to adjust the separation distance between the tip part of the laser emission unit and the tip part of the laser reception unit in accordance with the thickness of the packaging bag. [Solution] In this device G for measuring the gas concentration of a packaging bag, both the tip part of a laser generation unit 2 and the tip part of a laser reception unit 4 are disposed, so as to face each other, on the side of one of the surfaces (e.g., surface Ha) of a packaging bag H.
