The cold storage container of Patent Document 1 is an ordinary household container, is used repeatedly, and is not a food packaging material. The container used in Patent Document 2 is also a rigid wall such as a glass container, which is expensive and heavy to be disposable. Moreover, the two kinds of food materials are in direct contact with each other or separated only by the edible interface layer, and are not completely separated. Even when the separation is performed only by the edible interface layer, the food materials that can be separated are extremely limited.

Patent Document 3 also describes that a compartment pouch is provided, but in that case, the outer package and the inner pouch are manufactured separately, and it is necessary to separately feed and seal the foodstuffs. Furthermore, it is not easy to crush or break the pouch inside the package.

The present invention provides a food packaging bag in which a main food material and a fluid food material can be separately stored and the bag portion in which the fluid food material is stored can be easily broken to combine two kinds of food materials. The purpose is to provide.

In order to solve the above-mentioned problems, a food packaging bag of the present invention has a first bag portion for storing main ingredients and a second bag portion connected to an inner surface of an upper portion of the first bag portion, The weak connection part where the first bag part and the second bag part are weakly connected at the lower end part of the two bag parts, and the inner surface of the first bag part and the second bag part are stronger connected than the weak connection parts except the weak connection part. Has a strong connection. Then, a first bag portion in which the substantially rectangular first sheet and the second sheet are connected along the bottom side and the side edge, and a third sheet connected to the first sheet on the inner surface of the upper portion of the first bag portion A weak connecting portion that has two bag portions, and the first sheet and the third sheet are weakly connected by thermocompression bonding at the lower end portion of the second bag portion, and the first sheet and the third sheet other than the weak connecting portion. A strong connection portion that is more strongly connected than the weak connection portion by thermocompression bonding may be provided. Further, a cutting assist line may be provided on the first sheet and the second sheet below the weak connection portion.

In addition, the packaged food of the present invention has a first bag portion in which a substantially rectangular first sheet and a second sheet are connected along a bottom side and a side edge, and a third sheet is a third sheet on an inner surface of an upper portion of the first bag portion. A second connection part connected to one sheet, and a weak connection part where the first and third sheets are weakly connected by thermocompression bonding at the lower end part of the second bag part, and a second connection part other than the weak connection part. The 1st sheet and the 3rd sheet are packaged in a food packaging bag having a strong connection portion which is more strongly connected than a weak connection portion by thermocompression bonding,
The first bag portion contains the main food material, the second bag portion contains the fluid food material, and the first sheet, the second sheet, and the third sheet are weakened by thermocompression bonding at the upper side mouth portion. It is more strongly connected and sealed than the connection part. Vegetables may be selected as the main food material, and liquid seasonings may be selected as the fluid food material.

Since the food packaging bag of the present invention is a packaging material for a bag, it can be easily and inexpensively manufactured by stacking and connecting sheets. The two types of food can be stored separately, and when eating, the fluid food can be mixed so that it falls on the main food.

It is a top view which shows a food packaging bag. FIG. It is a front view which shows the 1st example of packaged food. It is a front view which shows the 2nd example of packaged food.

Embodiments for carrying out the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing a food packaging bag, and FIG. 2 is a sectional view taken along line AA of the same.

The food packaging bag 1 has a first bag portion 2 for storing main ingredients and a second bag portion 3 connected to an inner surface of an upper portion of the first bag portion 2. The second bag portion 3 is formed by connecting the sheet sandwiched inside the first bag portion 2 to the inner surface of the upper portion of the first bag portion 2. A weak connection portion 4 is formed at the lower end of the second bag portion 3 to weakly connect the first bag portion 2 and the second bag portion 3. Further, in a portion other than the weak connection portion, there is a strong connection portion 5 in which the inner surface of the first bag portion and the second bag portion are connected more strongly than the weak connection portion.

The food packaging bag 1 shown in FIG. 1 is in a state before packaging and is a bag body having an open upper portion. At the time of packaging, a main food material is placed in the first bag portion 2, a fluid food material that is a food material according to the second bag portion 3 is put, and the mouth portion is sealed by thermocompression bonding or the like to form a packaged food.

The first bag portion 2 is formed of a first sheet 6 and a second sheet 7 which have substantially the same shape. Then, the third sheet 8 is provided so as to be sandwiched between the first sheet 6 and the second sheet 7, and the second bag portion 3 is formed between the inner surface of the first sheet 6 and the third sheet 8. .. The first sheet 6, the second sheet 7 and the third sheet 8 are preferably made of a material having high airtightness and resistance to moisture and oil, and a plastic film or a composite sheet of plastic and paper is preferable. Further, the connection between the sheets is preferably such that the connection portion has a high sealing property, and for example, an adhesive or thermocompression bonding can be selected.

A more detailed description will be given based on the examples shown in FIGS. 1 and 2. In this example, the first sheet 6 and the second sheet 7 are substantially rectangular plastic films, and are transparent or translucent. The third sheet 8 is also a transparent or semi-transparent plastic film having a substantially rectangular shape, the width thereof is substantially the same as that of FIGS. 1 and 2, and the length thereof is shorter.

The first sheet 6 and the second sheet 7 are connected by thermocompression bonding along the bottom side and the side sides. This part is strongly bonded so as to have sufficient strength.

The first sheet 6 and the third sheet 8 are also connected by thermocompression bonding. In this example, the weak connection portion 4 is formed near the center of the bottom side of the third sheet 8, and the strong connection portion 5 is formed from both ends of the weak connection portion 4 to near the end portion of the upper side of the third sheet 8. Has been formed. The strong connection portion 5 is formed in an inverted C shape so as to spread from bottom to top.

The weak connection portion 4 and the strong connection portion 5 have different connection strengths, and the weak connection portion 4 is peeled off with a weaker force than the strong connection portion 5. In the case of thermocompression bonding, this difference in connection strength can be realized by changing the temperature of compression bonding. The crimping temperature of the weak connection portion 4 is lowered, and the crimping temperature of the strong connection portion 5 is raised. Alternatively, the width of the adhesive portion may be changed to make the width of the weak connection portion 4 smaller and the width of the strong connection portion 5 wider.

Further, in this example, the cutting assist line is provided on the first sheet and the second sheet below the weak connection portion. The cutting assist line 10 is provided above the height at which the main food material is stored.

There is no particular limitation on the main foodstuffs stored in the first bag portion 2, and for example, various foodstuffs such as chopped vegetables for salad, fried potatoes, and takoyaki can be used. Food materials suitable for addition to the main food material can be selected for the second bag portion 3, but fluid food materials are selected. Here, the fluidity may include liquid, cream, gel and the like as well as powder. That is, foods that do not have a fixed shape as a whole and can be easily moved downwards, such as dressing, mayonnaise, ketchup, sauce or other liquid or semi-liquid seasoning, salt, pepper, sugar, etc. Powdered food materials can also be selected.

Next, a first example of packaged food will be described. FIG. 3 is a front view showing a first example of packaged food. This packaged food 20 uses the food packaging bag of the example of FIGS. 1 and 2. Therefore, the substantially rectangular first sheet 6 and the second sheet 7 are connected to each other along the bottom side and the side side, and the third sheet 8 is the first sheet on the inner surface of the upper portion of the first bag section 2. A weak connecting portion 4 which has a second bag portion 3 connected to 6 and in which the first sheet 6 and the third sheet 8 are weakly connected by thermocompression bonding at the lower end portion of the second bag portion 3; In addition to the portion 4, the first sheet 6 and the third sheet 8 are packaged in the food packaging bag 1 having the strong connection portion 5 that is more strongly connected than the weak connection portion 4 by thermocompression bonding.

From the upper mouth of the food packaging bag 1, the chopped vegetables x for salad are put into the first bag portion 2 as a main ingredient. In addition, salad dressing y is put into the second bag portion 3 as a fluid food material from the mouth. Then, the packaged food 20 is obtained by performing thermocompression bonding on the mouth and connecting and sealing the first sheet 6, the second sheet 7, and the third sheet 8. Here, the thermocompression bonding of the mouth portion is stronger than the weak connection portion 4.

Thus, the chopped vegetables x for salad and the salad dressing y are completely separated and packaged. Therefore, the freshness of the raw vegetables is maintained for a long period of time.

When eating this food, first, the upper second bag portion 3 is pressed by hand and crushed. As a result, the internal pressure of the second bag portion 3 increases and the connecting portion between the first sheet 6 and the third sheet 8 is peeled off. Here, peeling starts at the weak connection portion 4 that is connected weaker than the other portions. Then, the salad dressing y, which is a fluid food material, flows out from the second bag portion 3 and into the first bag portion 2 from the peeling portion of the weak connection portion 4. Since the weak connection portion 4 is provided at the lowermost end of the second bag portion 3, almost all the salad dressing y flows out. In this way, the chopped vegetables x for salad and the salad dressing y are mixed in the first bag portion 2.

If you want to mix the chopped vegetables x for salad and the salad dressing y better, shake this food packaging bag. Since the first bag portion 2 is still sealed, the food material does not leak out. When mixed well, you can open the food packaging bag and eat the finished vegetable salad. The vegetable salad may be taken out on a plate and then eaten, but in this example, since the cutting assist line 10 is provided, it may be opened along the cutting assist line 10. When the portion above the cutting assistance line 10 is removed, the remaining lower bag portion becomes a container, and a salad or a fork can be inserted from the opening portion to eat a salad. Therefore, a disposable plastic fork may be used as a set.

According to the present invention, since the main food material and the fluid food material are mixed immediately before eating, the freshness of each food material is maintained.

A second example of packaged food will be described. FIG. 4 is a front view showing a second example of the packaged food. This packaged food 20 also uses the food packaging bag of the example of FIGS. 1 and 2, but when connecting the upper edges, the left and right corners B and C of the upper side of the original food packaging bag 1 are connected. Close the mouth so that they fit together. As a result, a substantially tetrahedral packaging body is formed. The second bag portion 3 also has a three-dimensional shape that extends in the front-back direction in FIG. The foodstuffs put in the first bag portion 2 and the second bag portion 3 may be the same as in the first example. Since the first bag portion 2 and the second bag portion 3 are three-dimensional, the volume is increased and more foodstuffs can be stored. In addition, it has a novel appearance that is different from the conventional packaged food.
