Sealed condition inspection device

A method of inspecting a sealed condition of an element comprising:

• positioning an element adjacent a pair of opposing electrodes, the element being fabricated of a material and comprising a sealed portion at which portions of the material forming the element are sealed together;
• contacting the opposing electrodes to the sealed portion of the element at opposite sides of the sealed portion;
• supplying electric current to the electrodes in contact with the sealed portion so that the opposing electrodes are oppositely charged;
• detecting an electrical variable in the sealed portion;
• and
• judging a sealed condition of the sealed portion based on the detected electrical variable.

A sealed condition inspection device for inspecting a sealed condition of a sealed portion of a contents containing element, wherein the sealed portion is formed by portions of the element being sealed together comprising

• a support unit for supporting the element to be inspected for the sealed condition,
• a pair of electrodes adapted to be positioned in contact with the sealed portion to be inspected at positions across from one another so that the sealed portion devoid of the contents is positioned between the pair of electrodes,
• an electrical variable detecting unit for detecting an electrical variable in the sealed portion to be inspected,
• a sealed condition device for judging the sealed condition of the sealed portion of the element based on the electrical variable, and
• wherein the sealed portion is folded down over a surface of the element, and one of said electrodes comprises a wedge shaped portion positionable under the folded down sealed portion.

A method of inspecting a sealed condition of an element comprising:

• positioning an element adjacent a pair of electrodes, the element being fabricated of a material and comprising a sealed portion at which portions of the material forming the element are sealed together, the sealed portion being folded down over a surface of the element;
• positioning one of the electrodes under the folded down sealed portion so that the one electrode is positioned between the surface of the element and a facing surface of the folded down sealed portion;
• contacting the electrodes to the sealed portion of the element at opposite sides of the sealed portion;
• supplying electric current to the electrodes in contact with the sealed portion;
• detecting an electrical variable in the sealed portion;
• and
• judging a sealed condition of the sealed portion based on the detected electrical variable.
