  • Method for checking the sealing of a package and apparatus for measuring viscosity
    Patent number: 5872309
    Abstract: A method for checking the sealing of a package, which includes a base part and a cover. A vibratory component is enclosed in a cavity in a gas of defined viscosity. Upon penetration from outside of a gas of different viscosity, the viscosity in the cavity, and thus also the vibratory properties of the vibratory element, are influenced. The sealing of the package can thus be checked at any time. The vibratory element can also be used generally to measure viscosity.
