工程数が増す嫌いがあった。(B) Prior art and problems When vacuum packaging, for example, sliced ham or other packaged items using a forming tool/packaging machine, especially a deep drawing type vacuum packaging machine, conventionally, for example, Japanese Patent Publication No. 56-355815 As disclosed in 2006, a pre-formed lower film with a molded recess for storing the packaged object is placed in the lower vacuum chamber, and the upper film is overlaid on the lower film to hold the packaged object. ,
After the inside of the molding recess is evacuated, the periphery of the packaged object is tightly sealed. However, in such conventional film sealing methods, when tightly sealing the periphery of the packaged object, the hot plate is lowered to heat and soften the upper film, and at that time the hot plate seals the packaged object. For this reason, it is possible to prevent the packaged items from being heated by making the heating plate recessed or using a weaker heating plate, but in the former case, the heating plate The shape structure becomes complicated, and the top film may be shaved into a concave shape and stretched.In the latter case, it takes time to heat and soften the top film prior to tight sealing, which reduces vacuum processing efficiency, which is another problem. occurs. Furthermore, the better the degree of tightness of the seal, the more difficult it will be to remove the packaged item from the product when opening the package.For this reason, V-cuts or other forms are usually applied to open the package, but the cut is formed after the sealing process. Therefore, another process is essential, which tends to increase the total number of processing steps.

。B) Structure of the Invention The film sealing method for a forming vacuum packaging machine according to the present invention includes:
In order to achieve the above purpose, the structure is such that the upper vacuum box has a first non-heating part that is slightly wider than the surface of the packaged product at the same position as the four formed parts of the lower film that come into contact during vacuum sealing. , Easy Open fJ [equipped with a movable heating plate provided with a second non-heating part of a corresponding position and size,
In the lower vacuum box facing the upper Makabe box, there is a space slightly larger than the molding recess of the lower film, and a seal receiving part that partitions each space and receives the hot plate with both the upper and lower films interposed between them. Equipped with. When vacuum-sealing the packaged items in the upper and lower vacuum boxes of a forming vacuum packaging machine, after creating a vacuum inside the upper and lower vacuum boxes, the hot plate is lowered to seal the surrounding area corresponding to the seal receiver slightly away from the packaged items. , leaving a non-sealed part for the easy open part in a part of the 7th part, first sealing, and then changing the inside of the lower vacuum box to atmospheric pressure, the pressure difference between the upper and lower vacuum hooks allows both the upper and lower sides to be closed. 7. The unsealed part of the film is brought into pressure contact with the lower surface of a hot plate, and the upper and lower films in the unsealed part are closely and secondary sealed together without heating the packaged item and leaving an easy-open part.

れない。The film sealing according to the present invention is carried out using such a molding vacuum packaging machine. Specifically, the inside of the vacuum box on both the upper and lower sides is sealed using a known method such as a vacuum line of a solenoid valve seal (not shown). ) to create a vacuum and lower the hot plate 2. As the upper vacuum box 1 is evacuated and the hot plate 2 is lowered, the upper film 11 comes into contact with the hot plate 2 and is heated and softened. However, at this time, the portions of the upper film 11 corresponding to the first non-heated portion T and the second non-heated portion 9 are not softened by heating.

分、更に加熱されることがない。By changing the pressure inside the lower vacuum box 3 to atmospheric pressure, a differential pressure is generated within the upper and lower vacuum boxes 1.3. [At this time, the inside of the upper vacuum box 1 remains evacuated. ] For this reason, the unsealed portions of both the upper and lower films 11, 4, 16. That is, the unsealed portion 15.16 left around the packaged object 6, especially the unsealed portion 15.16 of the upper film 11. is brought into pressure contact with the lower surface of the hot plate 2, and the upper and lower films 11.4 are closely and secondary sealed together while leaving the non-sealed part 14 for the easy open part 8. In the above-mentioned primary seal and secondary seal, the portion of the hot plate 2 corresponding to the packaged object 6 is provided with the first non-heating part 7, so that the packaged object 6 is heated. Never. Moreover, since the first non-heating portion 7 is made to have a slightly wider size than the surface of the object to be packaged 6, the surface of the object to be packaged 6 is not further heated.

分工程を省略できるという秀れた効果がある。(f) Effects of the invention The film sealing method for the forming vacuum packaging machine according to the present invention is as follows:
Since the content is as explained above, it has an extremely excellent effect, that is, (Since the first non-heating part was provided on the A+ hot plate,
Even when the hot plate is lowered and positioned directly above the packaged item, the packaged item is not heated at all, and the packaged item is uncured ham, other frozen foods, or fresh foods that do not like heat. The ability to vacuum seal without heating the packaged items further improves the quality of vacuum sealing. This leaves a non-sealed part for the easy-open part, which means that the easy-open part is formed on the product itself along with the seal. Conventionally, a separate process was required to form the V-cut for opening. It has the excellent effect of being able to omit the process compared to the other princesses.
