Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag suitable for packaging so-called processed food with broth such as boiled fish, which is composed of a solid matter boiled in a seasoning liquid and its broth. Is.

[0002]

2. Description of the Related Art In general, processed foods are generally processed foods in a packaging bag and packaged so as to be distributed at room temperature. After putting and packaging, distribute at refrigeration temperature (about 0-10 ° C), or after packaging at about 80-100 ° C for about 20-
Heated for 30 minutes, pasteurized and then chilled at a refrigerated temperature (0 to 10 ° C), or a chilled food that is appropriately processed. Or, when it is made into a frozen food which is frozen and distributed after being subjected to a pasteurization treatment of being heated at a temperature of about 80 to 100 ° C. for about 20 to 30 minutes after packaging, and a properly processed food. Approximately 15 at 120 ° C in a packaging bag
In some cases, a retort pouch food is prepared by high-temperature sterilization treatment of heating for up to 25 minutes and then distribution at room temperature.

By the way, when a so-called boiled processed food consisting of a solid substance boiled in a seasoning liquid and the broth such as the above-mentioned boiled fish is used as a room temperature food, a chilled food, a frozen food or a retort food. In any of the above cases, when the solid matter boiled in the seasoning liquid and the broth are put together in one packaging bag and packaged, the broth becomes solid during heat sterilization treatment, transportation and storage. Since it excessively penetrates into the product and becomes a boiled-boiled product, the fresh taste and flavor immediately after cooking in this type of processed food with broth are deteriorated.

Therefore, conventionally, when packaging processed foods with broth as described above, a gelling agent such as gelatin is added to the broth among the solid and the broth filled in one packaging bag, Boiled broth is gelled, or the solid matter and the broth are filled in separate packaging bags for packaging.

[0005]

However, gelling the broth as in the former can prevent the broth from penetrating into the solid during transportation and storage, but the broth becomes solid during the heat sterilization treatment. Not only can it be prevented from penetrating excessively, but also when heated prior to eating, the broth will penetrate too much into the solids, which will reduce the taste and flavor. From the viewpoint of taste, it may not be possible to use a gelling agent, and in addition, since the broth is gelled, there is a problem that it cannot be eaten without heating.

[0006] In the latter case, in which the solid matter and the broth are put in separate packaging bags for packaging, the separate packaging bags are prepared and the two packaging bags are combined into one. In addition to having to prepare a packaging bag that can be put together, the cost of packaging materials will increase, and the cost for significantly increasing the cost will be doubled because the number of steps for filling different packaging bags will be doubled. There is.

It is a technical object of the present invention to solve these problems all at once and to provide a packaging bag which can be manufactured at low cost.

[0008]

In order to achieve this technical object, the present invention provides a packaging film with an opening at one side edge to form a bag, and the opening of the bag is the opening. At a site between the one side edge and the other side edge opposite the one side edge,
A heat welding line for heat-sealing the front film and the back film in the bag body is provided, and the bag body is divided into a main storage portion near the one side edge and a sub storage portion near the other side edge,
Further, the heat welding line is provided with at least one narrow non-welding portion that communicates the inside of the main storage portion with the inside of the sub storage portion.

[0009]

[Operation] In this configuration, a processed food with broth consisting of a solid matter and broth thereof is filled into the main storage portion of the bag through the opening at one side edge, and then the bag is
A vertical orientation such that the opening at the one side edge faces upward, or a posture in which the auxiliary storage section is tilted so as to be lower than the main storage section, or the bag at the one side edge has an opening With the broth consisting of solid matter and its broth in the main storage part through its opening in a vertically oriented position or in a position where the sub-storage part is tilted so that it is lower than the main storage part. Fill with processed food.

Then, of the processed food with broth filled in the main storage part, solids remain in the main storage part, and only the broth is provided with a bag on a heat welding line which divides the main storage part and the sub-storage part. Since it flows down from the main storage part to the sub-storage part through the narrow non-welded part, the processed food with broth is automatically separated into solid matter in the main storage part and broth in the sub-storage part. It can be separated.

Therefore, in the same manner as described above, the bag body is set in a vertical posture so that the opening at one side edge thereof faces upward, or in a posture in which the sub storage portion is tilted so that it is lower than the main storage portion. In the state, at the opening at one side edge of the bag body, the front film and the back film in the bag body are heat-welded together and sealed, so that the processed food with broth is squeezed by one bag body. It is possible to package the solids and the broth of the processed foods separately.

Therefore, in the subsequent sterilization treatment by heating, the bag body is placed in a vertical posture so that one side edge thereof faces upward or in a posture in which the sub storage portion is tilted so as to be lower than the main storage portion. By heating in the state, it is possible to prevent the broth from penetrating into the solid material excessively,
Also, when heating before eating, the bag body is in a vertical position with one side edge facing upward or in a tilted position so that the sub storage unit is lower than the main storage unit. By heating with, it is possible to prevent the broth from permeating into the solid material excessively.

Further, even during handling such as transportation or storage, the bag body is tilted so that one side edge of the bag body faces upward or the sub-storage portion is lower than the main storage portion. By making the posture in such a state, it is possible to prevent the soup from permeating into the solid matter excessively. In order to reliably prevent the broth in the sub-storage part from flowing back into the main storage part through the non-welding part provided in the heat-welding line, after sealing the opening of the bag, the bag body is sealed. It suffices to close the non-welding portion by folding the two in two with the location of the heat welding line as a fold, or to close the non-welding portion by heat welding.

[0014]

Therefore, according to the present invention: It is possible to reliably package a processed food with boiling water such as boiled fish in a state where the fresh taste and flavor of the processed food immediately after cooking are not deteriorated. ． When filling the processed food with broth into the packaging bag, it is only necessary to fill the main storage part of the bag with the processed food with broth. As in the past, the solid matter and the broth are packed into separate packaging bags. Since it is not necessary to do so, it is possible to reduce the labor required for filling and the amount of packaging material. In addition to this, use a packaging bag that is very commonly used and do not weld to this bag body. Since it suffices to provide a heat welding line having a section, the cost required for packaging can be significantly reduced. Have the effect of.
