摘要： An internal pressure inspection apparatus for a sealed container having a can lid that is attached to any of an upper end and a lower end of a can trunk, and that is deformed by an internal pressure of the container. A laser sensor adapted to measure a distance from the can lid by irradiating the can lid is situated parallel to the can lid while being allowed to move relatively with the can lid. The inspection apparatus integrates relative displacement values between a reference point closer to a center of the can lid than a seamed portion and other points closer to a center of the can lid than the reference point, and acceptability of the internal pressure is judged based on the value of integration.

摘要： A method for inspecting sealing defects of a container using infrared light, which can be carried out to inspect all of containers in a non-contact and non-destructive manner using a comparatively inexpensive apparatus, even if it is not just after a heat sealing operation.
For this purpose, the infrared light in a wavelength range of 1450nm±20nm is irradiated from a phototransmitter onto the sealed portion of a sample container. The infrared light reflected from or transmitted through the sealed portion of the sample container is received by a photoreceiver 8, and transmitted to a photodetector 10 through an optical fiber 9. The photodetector 10 outputs a voltage according to an amount of the infrared light transmitted thereto, and the voltage thus outputted is then converted into an analog voltage value and further transmitted to a controller 12. The controller 12 sets a threshold based on the analog voltage value transmitted thereto. Then, the infrared light in a same wavelength range as the case of inspecting the sample container is irradiated onto the sealed portion of a container to be inspected. The infrared light reflected from or transmitted through the sealed portion of the inspected container is also converted into the analog voltage value and transmitted to the controller 12. If the infrared light is reduced to be smaller than the threshold set on the basis of the sample container, the sealed portion of the inspected container is judged as a sealing defect.摘要翻译： 一种使用红外光检查容器的密封缺陷的方法，即使不是在热封操作之后，也可以使用比较便宜的装置以非接触且非破坏性的方式检查所有的容器 。 为此，将1450nm±20nm的波长范围的红外光从光传递器照射到样品容器的密封部分上。 从样本容器的密封部分反射或透过的红外线由光接收器8接收，并通过光纤9传输到光电检测器10.光电检测器10根据传输到其的红外光的量输出电压 ，然后将这样输出的电压转换成模拟电压值，并进一步传输给控制器12.控制器12基于传输到其上的模拟电压值设定阈值。 然后，与检查容器的情况相同的波长范围的红外线照射到要检查的容器的密封部分。 从被检查容器的密封部分反射或透过的红外光也被转换为模拟电压值并传输到控制器12.如果红外光减小到小于基于样品容器设定的阈值 被检查容器的密封部分被判定为密封缺陷。

摘要： A canned product heating apparatus comprises: a non-contact type temperature detecting element 12 which is not in contact with a surface of a can container 2; a directional microphone 13 oriented to a closure 22 of the can container 2; an interrupting circuit which interrupts an electrical supply to a high-frequency induction heating coil 11 based on a signal transmitted from the directional microphone 13. The electrical supply to the high-frequency induction heating coil 11 is stopped by the interrupting circuit in case the directional microphone 13 captures sonic waves within a predetermined range.
