[0002]

2. Description of the Related Art Conventionally, in an airtight packaging bag or airtight packaging container for foods such as confectionery and other various articles, a mountain line parallel to a longitudinal central portion of a thin packaging material and two parallel valley lines outside the mountain line are formed. There is known a packaging bag invented by the present inventor, which has a band portion formed by bending as a reference, and a back surface of a rising portion and a back surface of the band portion between the peak line and the valley line are thermally bonded to each other. .
(Japanese Utility Model Publication No. 02-35647)

The present inventor has already proposed an apparatus for continuously forming the above-described band-shaped bent portion of a packaging bag from roll paper (Japanese Patent Application Laid-Open No. 05-55520). According to this, the apparatus comprises a fixed base having a T-shaped cross section or an inverted L-shaped cross section made up of a horizontal plate and a vertical plate at the center position in the width direction of the packaging material sliding on the base; A wrapping material bent portion composed of a pair of bent plates mounted in parallel with a horizontal plate and a vertical plate of a fixed base and a predetermined distance apart from each other, and a heat roller that rotates the heated portion by press-fitting the bent portion. , And a pinch roller for feeding paper. This is an apparatus configured to pull the packaging material in the moving direction while the packaging material is located between the horizontal plate and the bent plate and between the bent plate and the base.

[0004] Further, the inventors have also proposed a structure for preventing a container from being ruptured due to expansion of air or water vapor in a hermetically sealed package for heating having a band-shaped bent portion formed by the above-mentioned device (Japanese Patent Application Laid-Open No. Hei 7-1995). -267274). According to this configuration, a part of the heat-bonded seal portion of the bent band is formed weaker than the other seal portions, and a through hole or a cut hole is provided near the crest line of the bent portion. It is. Thus, when the thermal expansion occurs, the weak seal portion is firstly peeled off from the adhesive, and immediately after that, the container is not ruptured by communicating with the atmosphere through a through hole or a cut.

[0005]

A bag-shaped container having a band-shaped bend is not limited to a certain degree of resistance to explosion and rupture. In particular, in recent years, consumer needs have been upgraded, and additional functions such as stimulation of purchase will have been required. Demands for designs that have been diversified from uniform ones are increasing in the industry. In order to respond to such a demand, it is not enough to use only a band-shaped bend formed at the center in the width direction as in the past.
It has become necessary to form a band-like bend at an arbitrary position in the width direction.

According to a test conducted by the inventor of the present invention, wrinkles are more likely to occur in the packaging container in the subsequent heat bonding step as the band-like bending position of this type of packaging material is shifted from the center in the width direction of the packaging material. However, it was recognized that the appearance was unsightly, and it was necessary to improve a molding apparatus which does not cause such a defect.

Further, conventionally, a separate process of forming and bonding a band-shaped bent portion using a packaging material provided with an expansion-rupture-resistant open hole in advance as a starting material has been exclusively employed. Therefore, since the productivity is low and the cost is high, an integrated process has been demanded.

[0008] In view of the above circumstances, the present inventor forms a band-like fold in the length direction at an arbitrary position in the width direction of the wrapping material, and does not generate wrinkles in the wrapping container in the heat bonding process of the fold. We have invented a bending machine with characteristics and have already filed an application. According to the present invention, the apparatus according to the above invention is further modified to form a band-like bend at an arbitrary position in the width direction of the heated packaging material, and furthermore, to create an open mouth for preventing the container from bursting during heating. It is an object of the present invention to provide a continuous manufacturing apparatus of a hermetically sealed package for heating, in which a weak adhesive bond is formed.
