JP 2011-88656 A JP-T-2001-509022 Japanese Patent Laying-Open No. 2015-50945

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

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

The present invention provides a food packaging bag that can separate and store a main ingredient and a fluid ingredient, and can easily break a bag portion in which a fluid ingredient is accommodated to combine two kinds of ingredients. The purpose is to provide.

In order to solve the above-described problems, a food packaging bag according to the present invention includes a first bag portion for storing main ingredients, and a second bag portion connected to the upper inner surface of the first bag portion. The weak connection part in which the 1st bag part and the 2nd bag part are weakly connected in the lower end part of 2 bag parts, and the 1st bag part inner surface and the 2nd bag part are connected more strongly than the weak connection part except the weak connection part Has a strong connection. And the 1st bag part to which the 1st sheet and 2nd sheet of a substantially rectangular shape were connected along the bottom and the side, and the 3rd sheet to the 1st sheet in the upper inner surface of the 1st bag part The first sheet and the third sheet except for the weak connection part, and the weak connection part having the two bag parts, the first sheet and the third sheet being weakly connected by thermocompression bonding at the lower end part of the second bag part. You may provide the strong connection part connected more strongly than the weak connection part by thermocompression bonding. Furthermore, a cutting auxiliary line may be provided on the first sheet and the second sheet below the weak connection portion.

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

Since the food packaging bag of the present invention is a packaging material for bags, it can be easily and inexpensively manufactured by stacking and connecting sheets. Two types of ingredients can be separated and stored, and when eaten, fluid ingredients can fall on top of the main ingredients and mix.

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.

EMBODIMENT OF THE INVENTION The form for implementing this invention is demonstrated in detail based on drawing. FIG. 1 is a plan view showing a food packaging bag, and FIG. 2 is a cross-sectional view taken along the line AA.

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

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

The first bag portion 2 is formed of a first sheet 6 and a second sheet 7 having substantially the same shape. 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 airtight and are preferably a material resistant to moisture and oil, and are preferably a plastic film or a composite sheet of plastic and paper. Further, the connection between the sheets is preferably one having high sealing performance at the connection portion, and for example, an adhesive or thermocompression bonding can be selected.

This will be described in more detail based on the example shown in FIGS. 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 substantially rectangular transparent or translucent plastic film, the width is substantially the same as in FIGS. 1 and 2, and the length is shorter.

The first sheet 6 and the second sheet 7 are connected along the bottom and side by thermocompression bonding. 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 in the vicinity of the central portion of the bottom side of the third sheet 8, and the strong connection portion 5 extends from both ends of the weak connection portion 4 to the vicinity of the end portion of the upper side of the third sheet 8. Is formed. This strong connection part 5 is formed in the shape of an inverted letter C which spreads from the bottom to the 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, for example, by changing the temperature of pressure bonding. The crimping temperature of the weak connection part 4 is lowered, and the crimping temperature of the strong connection part 5 is increased. Or the width | variety of an adhesion part may be changed, the width | variety of the weak connection part 4 may be made smaller, and the width | variety of the strong connection part 5 may be made wider.

Furthermore, in this example, the cutting auxiliary line is provided in the 1st sheet | seat and the 2nd sheet | seat below the weak connection part. This auxiliary cutting line 10 is provided above the height of the main food.

There is no restriction | limiting in particular in the main foodstuff accommodated in the 1st bag part 2, For example, it can use for various foodstuffs, such as a chopped vegetable for salad, a fried potato, and a takoyaki. A food suitable for adding to the main food can be selected for the second bag portion 3, but a fluid one is selected. Here, the fluidity may include liquid, cream, gel, etc., as well as powder. In other words, any food that does not have a fixed shape as a whole and can be easily moved downward, such as dressings, mayonnaise, ketchup, sauces, and other liquid or semi-liquid seasonings, salt, pepper, sugar, etc. Powdered foods 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 FIG. 1 and FIG. Therefore, the 1st bag part 2 to which the substantially rectangular 1st sheet | seat 6 and the 2nd sheet | seat 7 were connected along the base and the side, and the 3rd sheet | seat 8 in the upper inner surface of the 1st bag part 2 are the 1st sheet | seat. Weak connection part 4 which has the 2nd bag part 3 connected to 6, and the 1st sheet 6 and the 3rd sheet 8 are weakly connected by thermocompression bonding in the lower end part of the 2nd bag part 3 The first sheet 6 and the third sheet 8 other than the part 4 are packaged in the food packaging bag 1 having the strong connection part 5 to which the weak connection part 4 is connected more strongly by thermocompression bonding.

As a main ingredient from the mouth part at the top of the food packaging bag 1, chopped vegetables x for salad are put into the first bag part 2. Moreover, the salad dressing y is thrown into the 2nd bag part 3 as a fluid foodstuff from a mouth part. And the packaged food 20 is obtained by thermocompression-bonding to a mouth part, connecting the 1st sheet | seat 6, the 2nd sheet | seat 7, and the 3rd sheet | seat 8, and sealing. Here, the thermocompression bonding of the mouth portion is also connected more strongly than the weak connection portion 4.

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

When eating this food, first, the upper second bag portion 3 is crushed by pressure by hand. Thereby, the internal pressure of the 2nd bag part 3 increases, and the connection part of the 1st sheet | seat 6 and the 3rd sheet | seat 8 peels. Here, peeling starts at the weak connection portion 4 that is connected weaker than the other portions. Then, salad dressing y, which is a fluid food material, flows out from the second bag portion 3 from the peeling portion of the weak connection portion 4 and flows into the first bag portion 2. Since the weak connection part 4 is provided in the lowest end of the 2nd bag part 3, almost all the salad dressing y flows out. In this way, the chopped vegetable x for salad and the salad dressing y are mixed in the first bag part 2.

If you want to mix chopped vegetable x for salad and salad dressing y better, you can shake this food packaging bag. Since the 1st bag part 2 is still sealed, a foodstuff does not leak outside. When mixed well, you can open the food packaging bag and eat the finished vegetable salad. Although the vegetable salad may be eaten after being taken out to the plate, in this example, since the cutting auxiliary line 10 is provided, it may be opened along the cutting auxiliary line 10. When the upper part of the cutting auxiliary line 10 is removed, the remaining lower bag part becomes a container, and a salad can be eaten by inserting a ladder or fork through the opening. Therefore, a disposable plastic fork may be set.

According to the present invention, the main ingredients and the fluid ingredients are mixed immediately before eating, so that the freshness of each ingredient is maintained.

A second example of the 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 FIG. 1 and FIG. 2, but when connecting the upper edge, Close the mouth to fit. Thereby, a substantially tetrahedral package is formed. The 2nd bag part 3 also becomes a three-dimensional shape which extended also in the front-back direction in FIG. The foodstuffs put into the 1st bag part 2 and the 2nd bag part 3 may be the same as a 1st example. Since both the first bag portion 2 and the second bag portion 3 are three-dimensional, the volume is increased and more food can be stored. Moreover, it has a novel appearance different from conventional packaged foods.
