- the container is determined by measuring the enormous dimensions of the container.
- the inspection object M is accommodated in the sealed container 30 of the inspection apparatus 10 for the inspection object M filled with a beverage in a rectangular parallelepiped paper pack container. 30 communicates with a decompression means 40 having a known vacuum pump (not shown) as a component through a vacuum pipe 35. Then, the air inside the sealed container 30 is sucked by the vacuum pump, and the pressure is reduced to a negative pressure sufficient for the container outer walls Kl and K2 of the object M to be inflated.
- a decompression means 40 having a known vacuum pump (not shown) as a component through a vacuum pipe 35.

- the inspection object is inspected by the total value of the enormous dimensions of the outer wall on both sides of the paper pack container, but it is only easy to swell the container outer wall in one direction such as a cup-shaped or bag-shaped container. If the container cannot be measured, the container inspection according to the present invention can be carried out by measuring the huge dimension of one part of the container.
- the present invention performs decompression sufficient for enlarging the container outer wall of the object to be inspected, measures the enormous dimension of the outer wall of the container, and sets a predetermined threshold value for the enormous dimension of the outer wall at a predesignated decompression value.

Air that is intentionally injected into the object to be inspected and mixed into the milky beverage, and for objects that are poorly sealed, an object with a 0.2 mm ⁇ hole in the paper pack container must be opened. lj is used.
- the outer wall of each container starts enormously after the start of decompression of the sealed container.
- the enormous situation rapidly increases in the order of excessive air mixing, poor sealing, and non-defective products.
- the difference in the enormous velocity of the outer wall of the container is that the air present in the container of the object to be inspected with excessive air reacts most quickly to the surrounding pressure drop, and the volume is expanded to enlarge the outer wall of the container. This is probably because of this.
- the surrounding liquid pressure drops faster than a non-defective product due to the influence of the poorly sealed part of the container, in this case the 0.2 ⁇ hole.
- the dissolved air in the liquid is separated in response to this, and this separated air expands and enlarges the outer wall of the container.
- the outer wall of the flexible container is pulled by the surrounding negative pressure and the inside of the container becomes negative pressure. It is thought that the outer wall of the container will be enormously delayed by the inspection object.

- atmospheric pressure minus 94kPa For highly flexible containers, it was possible to effectively identify good products, poor sealing, and excessive air contamination.
- at a negative pressure of less than atmospheric pressure minus 94 kPa it is difficult to efficiently inspect and identify the object to be inspected because of the relatively high rigidity of paper bags and the like, and the container is sufficiently large in a short time. It is thought.
- the pressure reduction set value at high vacuum above atmospheric pressure minus lOOkPa is not required in practice, and considering the performance and cost of the vacuum pump, there is no particular limitation, but the range from atmospheric pressure minus 94kPa to lOOkPa It can be used as an area of the ultimate pressure reduction setting value for performing high-precision inspection for many inspection objects.
- the non-defective product and the defective product were identified by comparing the enormous size of the object M to be inspected at the specified inspection decompression value Pk with a threshold value.
- the pressure drop inside the sealed container 30 is approximately proportional to the time after the start of decompression, instead of the specified inspection decompression value Pk, the enormous dimension of the inspection object M at the specified elapsed time Tk after the start of decompression is measured. , Pre-specified The inspection object M can be inspected in comparison with the threshold value.

Reducing the pressure in container 30 to P1 and then returning to atmospheric pressure. At this time, the air in the filling liquid such as beverage in the container is separated in advance in the decompression process, and the enormous volume of the outer wall of the container is accelerated during the inspection of the inspection object M, and the difference depending on the state of the inspection object Appears clearly. For this reason, it is possible to measure the difference between inspection objects in a short time compared with the case where preliminary decompression is not performed, and to identify air overload, sealing failure, and non-defective products more clearly, and more accurate inspection. Can be performed efficiently.
