っていた。2. Description of the Related Art Conventional vacuum deaeration packaging is disclosed, for example, in Japanese Patent Laid-Open No.
The one disclosed in Japanese Patent No. 1-40291 stores a packaging bag in which a bag mouth is temporarily sealed to the extent that the contents are not exposed in a vacuum chamber, and the inside of the chamber is evacuated.
The packaging bag is shaped and completely sealed in a vacuum. In this vacuum deaeration packaging, it is necessary to seal the bag mouth in two steps, which causes a decrease in processing capacity. In addition, the vacuum deaeration process is expensive and complicated as a whole, such as providing a sealing machine in the vacuum deaeration vacuum chamber.

Disclosed is one in which a packaging bag sealed in a zigzag shape or a labyrinth so that a bag mouth of a packaging bag filled with contents communicates with the inside and outside of the packaging bag is evacuated in a vacuum chamber. This one does not require a special device or process together with the packaging device and the vacuum deaeration device, and is capable of vacuum deaeration shaping without lowering the capacity. In other words, the packaging bag with the zigzag or labyrinth-like seal described above is put into a vacuum deaeration device, and the packaging bag is pressed and vibrated while degassing from the minute gap of the bag mouth in the vacuum chamber of the vacuum deaeration device. Is added for shaping.

った形状となる。A conventional example will be described with reference to FIGS. The bag mouth 10 of the packaging bag 9 filled with the contents has a linear seal shape. When the packaging bag 9 provided with such a seal is put into the vacuum chamber and the vacuum pressure is increased, the packaging bag 9 expands greatly due to the pressure difference between the vacuum chamber and the packaging bag 8. At this time, the minute gap 1 communicating with the inside and outside of the packaging bag 9 also expands. Since the seal shape is linear, the minute gap 1 is also linear, and the minute gap 1 expands into the tunnel-shaped air passage 7 along this linear seal shape. In this way, the minute gap 1 releases the atmospheric pressure in the packaging bag 8 to the outside of the bag. However, since the linear seal is provided in the width direction of the packaging bag 9, most of the length of the minute gap 1 is small. The tunnel-shaped air passage 7 having the minute gap 1 in the width direction of the packaging bag 9 extends in the width direction of the packaging bag 9.
Becomes Further, the vicinity of the bag mouth 10 of the packaging bag 9 also has a shape along the seal shape.

ることは困難である。The air in the packaging bag 8 passes through the minute gap 1 and is discharged from the broken portions 2 and 3 of the linear seal to the outside 4 of the packaging bag and into the vacuum chamber. Air must be expelled approximately perpendicular to the seal. That is, the tunnel-shaped air passage 7 of the minute gap 1 has a shape extending in a direction perpendicular to the direction in which air is emitted, and the tunnel-shaped air passage 7 becomes a pipe and the length of the wall surface of this pipe. The air in the packaging bag 8 is discharged from the gaps (disconnection portions) 2 and 3 put in the direction. In other words, the greater the pressure difference inside and outside the packaging bag,
Since the packaging bag 9 expands and the shape of the tunnel-shaped air passage 7 becomes clearer, the gaps (broken line portions) 2 and 3 inserted in the length direction of the pipe are connected to the packaging bag 9 by the tunnel-shaped air. Road 7 closes it. However, if the vacuum pressure in the vacuum chamber is high, it is possible to forcibly deaerate the atmosphere in the packaging bag 8 by pressing or the like even when the gap 3 (broken line portion) 3 is closed. However, since the vacuum pressure in the vacuum chamber is high, the packaging bag 9 after vacuum deaeration shaping also has a high vacuum pressure in the packaging bag 8 and is a hard shaping packaging bag.
Furthermore, it is difficult to make a soft orthopedic bag product with this seal.

Become. Also, it was performed in a short time. However, since a vacuum deaeration shaping bag shaped with a high vacuum pressure is likely to be broken by the impact of subsequent transportation and handling, the packaging bag that can absorb this impact has a low vacuum pressure and is somewhat flexible. I came to ask for a bag.

Therefore, when the vacuum pressure is high, the vacuum degassing is surely performed at high speed. Formed but low vacuum pressure, eg -100mm
When it becomes less than Hg, not only time is required for vacuum degassing and shaping, but also the vacuum pressure of the vacuum degassed packaging bag varies, or when vacuum shaping is difficult when the vacuum pressure in the vacuum chamber is set lower. Was also occurring.

A packaging bag having an intermittent linear seal, wherein the inner seal portion that opposes the broken portion of the linear seal at the outer position is formed in a non-linear shape, and the linear seal at the outer position is formed. The seal disconnection portion is provided at a plurality of positions in the seal portion at the inner position facing the continuous portion of, and the above-mentioned problem is solved by arranging the insides of the packaging bags of the plurality of seal portions separated by the seal disconnection portion in an alternating manner.

いな真空脱気整形包装を可能としたものである。In general, the bag mouth of a packaging bag is generally sealed in a straight line in the width direction of the bag mouth. This is not effective even if a seal of a shape other than a straight line such as a zigzag shape is implemented, and not only does the processing cost of the seal base (heat bar) increase, but conversely, for example, a zigzag shape seal other than a straight line, This is because the pressure on the bag mouth of the packaging bag due to the impact during transportation may concentrate on the edge portion of the zigzag seal and cause the bag mouth to be destroyed.
From this, a linear seal becomes the mainstream, but the present applicant has clarified that in vacuum degassing, this linear seal is the cause of prolonging the degassing time related to vacuum degassing packaging, Even with the simplest straight seal, it is possible to perform plastic packaging by vacuum degassing in a short time and clean vacuum degassing plastic packaging even at low vacuum pressure.

The inner seal portion that opposes the disconnection portion of the linear seal is formed in a non-linear shape, and a plurality of seal disconnection portions are provided in the seal portion at the inner position facing the continuous portion of the linear seal at the outer position. The insides of the packaging bag of the plurality of seal portions separated by the seal disconnection portion are arranged alternately.

でなく、低い真空圧でも真空脱気整形が可能となった。During vacuum shaping, the inner seal portion, which opposes the broken portion of the linear seal at the outer position, is formed in a non-linear shape, so that the air passage between the two linear seals is formed. An air passage connecting between the outside and the outside of the packaging bag is surely secured. In addition, by arranging the insides of the packaging bags of the plurality of seal portions at the inner positions separated by the seal disconnection portion in an alternating manner, the air that communicates between the air passage between the two linear seals and the inside of the packaging bag It is possible not only to reliably secure the passage, to quickly release the atmosphere in the packaging bag from the air passage that communicates with the inside and outside of the packaging bag, but also to enable vacuum deaeration and shaping even at low vacuum pressure. ..
