However, in the mixing packaging bag as described above, the compartment seal part has a compartment that is partitioned at the time of distribution, etc., but has a structure that can be peeled off and mixed with different contents during use. Is necessary, but small quantities such as liquids, viscous materials and liquids, viscous materials, or salts (powder) and water (liquid), antibiotics (powder) and infusions (liquid), etc. Although packaging bags for mixing powders with large amounts of highly soluble liquids are known, to date, the packaging bag has the same amount as liquids and powders. On the other hand, the fact is that no satisfactory product has been proposed.
For example, a conventional mixing packaging bag stores powder and liquid in the same amount in two chambers, and then peels off the division seal section divided into the two chambers, so that the packaging bag can be removed from the outside. Even when the powder and liquid are mixed, so-called “dama” is easily generated as a lump of undissolved powder at the corner of the peripheral seal portion of the packaging bag, and the viscosity of the mixture increases. Therefore, it is difficult to uniformly mix the powder and the liquid.
In addition, in conventional mixing packaging bags, pinholes may be generated in the corners inside the outer peripheral edge during transportation or due to external impacts such as dropping, and the contents may leak from that portion. There is.
Further, in the conventional packaging bag for mixing, if the inner dimension of the section seal portion is a bag shape longer than any inner dimension of the two chambers orthogonal to the section seal section, the outer peripheral end portion is more than the section seal portion. There is a possibility that pressure is applied to the seal portion and the seal portion at the outer peripheral end is opened.
For example, in the packaging bag described in the above-mentioned Patent Document 1, a seal portion is provided in the peripheral portion to form a bag body, and a part of the bag is used as a temporary bonding portion that divides the bag body into two chambers. -Since the seal portion is provided via a dip peel tape, the position of the seal when the heel peel tape is interposed and sealed in the packaging bag There is a drawback that it is necessary to seal so as not to shift, and it is necessary to make the bag making machine difficult.

Conventionally, when cooking okonomiyaki, takoyaki, hot cake, crepe, etc. as a powder and mixing ingredients and liquid, water or a seasoning liquid mainly composed of water, just before cooking, The ingredients are weighed with a measuring cup or the like and placed in a bowl or the like, stirred with a whisk or the like, mixed uniformly, and then cooked.
For this reason, in the measurement of liquids such as the above-mentioned powdery constituent materials and seasoning liquids, it is impossible to cook properly if the measurement of each material is mistaken.Therefore, there is a complicated operation of measurement. It was necessary to clean the used containers and measuring cups.

Conventionally, as for impression materials for taking a tooth profile used in a dental clinic, a raw powder mainly composed of alginate and water or a liquid mainly composed of water are weighed with a measuring spoon, a measuring cup, etc. It is known that it is taken up in a ball made of the product, stirred and mixed using a spatula or the like, and then poured into a tooth taking device and cured to take a tooth form.
In material weighing, if the material weighing operation is incorrect, it does not harden as set, and there is a complicated operation of weighing, and when mixing raw material powder and water, curing will proceed if the impression material is left in the mixed state For this reason, speed and skill are required for the stirring and mixing work.Furthermore, after mixing, the impression material adheres to the container and spatel used for mixing in a cured state, so a long cleaning work is required. there were.

  Therefore, the present invention improves the bag shape, the ratio of the dimensions of the chamber and the division seal part, the shape of the chamber, the shape of the division seal part, etc. in the packaging bag for mixing powder and liquid, Although the chamber is partitioned, the contents of the same amount of powder and liquid can be mixed easily by selectively peeling only the section seal part without opening to the peripheral seal part in use. Furthermore, it is an object of the present invention to provide a packaging bag useful for mixing powder and liquid, which can be used and does not leave undissolved powder at the corners of the peripheral seal and can be mixed uniformly.

FIG. 8 is a schematic view illustrating the seal shape of the division seal portion in the packaging bag according to the present invention. FIG. 9 is a schematic view of the outer peripheral end seal portion in the packaging bag according to the present invention. FIG. 10 and FIG. 11 are plan views illustrating an example of the seal shape inside the outer peripheral end portion in the packaging bag according to the present invention. FIG. 12 is a plan view illustrating the seal shape. Of the structure of the packaging bag according to the present invention manufactured using the laminate shown in FIG. Example is a perspective view showing a.

First, in the present invention, as a laminate constituting the packaging bag, as shown in FIG. 1, at least the base material 2 and the easy peel layer 4 are sequentially laminated from the outside to the inside. A laminate 10 can be used.
In addition, in the above, it can laminate | stack on the base material 2 and the easy peelable layer 4 via an adhesive bond layer.
Next, in this invention, as another laminated body which comprises a packaging bag, as shown in FIG. 2, it is at least the base material 2, the intermediate | middle layer 6, and an easy peel property layer from the outer side toward the inner side. 4 can be used. In the above, the intermediate layer 6 may be a barrier layer or a layer imparting pinhole resistance.

Next, an example of the structure of the packaging bag according to the present invention will be described by exemplifying a packaging bag manufactured using the laminate 10 shown in FIGS. 1 to 2. As shown in FIG. Using the laminate 10 manufactured in the above, the surface of the easy peelable layer 2 is overlapped facing each other, and the section seal portion 12 for partitioning the chamber by heat fusion is provided in two chambers parallel to the section seal portion 12. The two chambers 24 and 26 are divided so that the inner dimension L is shorter than any of the inner dimensions M and N in the direction orthogonal to the section seal portion, and powder is divided into each of the two chambers partitioned by the section seal portion 12. A chamber 24 for storing the powder 14 and a chamber 16 for storing the liquid 16 by storing the body and liquid contents 14 and 16 and sealing the peripheral portion 8 of the outer peripheral end of the packaging bag by heat sealing. 16 and the above-described section seal portion 1 when used. The by peeling is to produce a packaging bag 20 which is capable of mixing the contents 14, 16 of the powder and liquid.
