Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a packaging bag for packaging foods such as chicken and fish in a vacuum state.

[Prior Art] Generally, foods such as smoked chicken and smoked salmon are produced by smoking chicken thighs or half-grated salmon. Recently, however, smoked foods have become popular, in which whole chickens with only the internal organs removed or salmon with the bellies and internal organs removed are smoked as they are, in order to maintain an appearance that is more similar to the raw material. It's coming.

FIG. 9 is a perspective view showing a conventional smoked chicken. This smoked chicken 10 is prepared by smoking and cooking a whole chicken whose neck has been cut off and its internal organs taken out. The smoked chicken 10 cooked in this manner has a hollow portion 11 formed by removing the internal organs.

The smoked chicken 10, which is still round and has a hollow portion 11, is housed in a transparent bag 12 made of polyester or the like in the direction of arrow A [see FIG. 9]. The bag 10 has an overall rectangular parallelepiped shape as shown in FIG. 10, and when the smoked chicken 10 is housed inside the bag 12, the air inside the bag is sucked into the bag through the opening 13 of the bag 12. In this state, the opening 13 of the bag 12 is heat sealed. When the heat-sealed portion 14 is formed in the opening 13 of the bag body 12, the smoked chicken 10 having the hollow portion 11 is attached to the bag body 1.
2, the inside is vacuumed and sealed and packaged [see Figure 11].

The smoked chicken 10 sealed and packaged in the state shown in FIG. 11 is immersed in a hot water tank for a certain period of time. As a result, airborne bacteria attached to the surface of the smoked chicken 10 are thermally sterilized from the outside of the bag 12 before it is housed in the bag 12.

[Problems to be Solved by the Invention] However, when the smoked chicken 10 is sealed and packaged in a vacuum state inside the bag 12 having an overall rectangular parallelepiped shape as described above, when the air inside the bag 12 is sucked, Hollow part 11 of smoked chicken 10
The air inside will also be sucked in. As a result, the smoked chicken 10 that is hermetically packaged with the opening 13 heat-sealed has a collapsed shape as the air in the hollow part 11 escapes, and the appearance is more similar to that of the raw material. It becomes impossible to express the shape. Moreover, air tends to remain in the hollow part 11 of the smoked chicken 10, which is kept in a sealed state, and perfect vacuum packaging may not be possible. Therefore, the hollow part 1 where air remains
Airborne bacteria grow inside the food storage area, which poses a problem in the sanitary storage of food.

In addition, 10 pieces of smoked chicken are cooked inside the boiling water tank.
When sterilizing airborne bacteria adhering to the surface of bag body 1,
Although heat sterilization of the outer portion in contact with the inner surface of the bag body 12 is possible, the hollow portion 11 that is not in contact with the bag body 12
The surface of the food was said to be difficult to sterilize using boiling water, and this was also considered a problem in sanitary food storage.

An object of the present invention is to hygienically package a food product having a hollow portion while maintaining the appearance of the food product.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides packaging in which a food having a hollow portion is housed inside a bag, and the food is hermetically sealed while the inside of the bag is in a vacuum state. In the bag, the bag body is provided with a pouch portion that hermetically covers the inner surface of the hollow portion under a vacuum condition inside the bag body.

[Function] According to the present invention, the hollow portion of the food is hermetically encapsulated by the pouch portion of the bag, and the entire surface of the food, including the hollow portion, can be completely vacuum packed with the entire bag. becomes. This makes it possible to hygienically package a food having a hollow portion while maintaining the appearance of the food.

The smoked chicken 20 shown in FIG. 1 is formed by smoking a whole chicken whose neck has been cut off and its internal organs and feathers removed. That is, the smoked chicken 20 is formed by first cutting off the neck and removing the internal organs from the cut neck of the chicken from which the feathers have been removed. Next, the surface portion including the hollow portion 21 from which the internal organs have been removed is washed with water or the like, and the washed chicken surface is seasoned and cooked. Once seasoned, the whole chicken is smoked for several hours using beech, cherry, or other wood chips. The whole smoked chicken 20 that is cooked and formed in this manner is vacuum packaged by the bag body 22.

The bag body 22 is made of a transparent resin material pasted with a synthetic resin film, and has an opening 23 at one end. The bag body 22 has a pouch portion 24 attached to the center on the other end side with respect to the opening portion 23. That is, the pouch portion 24 is formed in such a manner that a small pouch protrudes from the main body portion of the pouch 22 . The smoked chicken 20 is stored in the bag 22 by being inserted from the opening 23 in the direction of arrow B, as shown in FIG. At this time, the smoked chicken 20 is
