Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a stick-shaped packaging bag for accommodating contents such as powder and granules.

[Conventional technology]

Conventionally, three-way or four-way seal packaging bags have been used for packaging powdered or granular medicines. In the packaging of this medicine, normally, the adult dose and the dwarf dose are not separately packaged, but a fixed amount of the drug is always contained in each packaging bag. For this reason, 1 adult, dwarf
The prescription is 1/2 package, and in order to take out 1/2 package for a small child, after taking out the whole amount from a general bag, it was divided into half according to the eye size.

[Problems to be solved by the device]

However, not only is it troublesome to take out the whole amount and then divide it in half, but there is a problem in that the divided amount varies considerably.

The present invention has been made in view of the problems of the present invention, and an object of the present invention is to provide a packaging bag capable of easily and relatively accurately extracting a predetermined amount of contents.

[Means for Solving the Problems] The present invention, which has been made to achieve the above object, has at least a stick-shaped inner bag containing the contents, and an inner bag containing the inner bag and the contents outside the inner bag. And a stick-shaped outer bag which is housed therein, and both ends of the inner bag are fixed to both ends of the outer bag, and the inner bag has an intermediate seal portion for sealing the inner bag near one end thereof. The gist of the present invention is a multi-layered stick packaging bag, wherein the outer bag has a cutting position indicating means at a position sandwiching the intermediate seal portion of the inner bag.

[Action]

According to the packaging bag having the above-mentioned configuration, when the packaging bag is cut in accordance with the cutting position indicating means above the intermediate seal portion, the outer bag is opened, but the inner bag has the intermediate seal portion, so that the inner bag remains sealed. Becomes As a result, only the contents in the outer bag can be taken out. Also, when the packaging bag is cut according to the cutting position indicating means below the intermediate seal portion, the outer bag,
The inner bag can be opened at the same time and the entire contents can be taken out.

〔Example〕

FIG. 1 is a schematic perspective view of a packaging bag for drug packaging according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line II-II of FIG. 3, and FIG. FIG. 4 is a schematic plan view showing the packaging bag in a disassembled state. The packaging bag generally designated by reference numeral 1 is an outer bag 2 made in a stick shape with a packaging material such as plastic film or synthetic paper, and a stick bag made with a packaging material such as a plastic film or synthetic paper. 2 and an inner bag 3 housed in the outer bag 2. A predetermined amount of medicine is contained in the outer bag 2 so as to be outside the inner bag 3, and a predetermined amount of medicine is also stored in the inner bag 3. Is stored as the contents 5. The amount of contents 4 and 5 will be the amount for adults when both are combined, and the amount of contents 4 in outer bag 2 alone will be the amount for dwarfs (for example, half of the amount for adults). It is set.
The outer bag 2 and the inner bag 3 have back seal portions 2a and 3a and have substantially the same length, and both ends thereof are sealed and fixed to each other by sealing both ends thereof with the seal portions 2b and 3b. Although the outer bag 2 and the inner bag 3 are both of the back seal type in this embodiment, the seal type is not limited to this and may be a side seal or the like.

The inner bag 3 has an intermediate seal portion 3c that seals the inner bag 3 at a position near one end thereof and away from the seal portion 3b. On the other hand, the outer bag 2 has cut position indicating lines 6a and 6b formed by printing as an instruction means for instructing the cut position at a position sandwiching the intermediate seal portion 3c of the inner bag 3. The instruction means is not limited to the instruction lines 6a and 6b formed by printing, and other means may be used. For example, when the outer bag 2 is a side seal type, a notch or V notch is formed in the seal so that the seal can be easily torn, and the notch, V
A notch or the like may be used as the indicating means.

The packaging bag 1 having the above structure can be manufactured as follows. That is, the long packaging material is filled with the contents while forming a bag, and the continuous inner bag 3 is created, and then the long packaging material is formed into the bag shape and the inner bag 3 and the contents are filled. After filling, it can be manufactured continuously by sealing and cutting the end.

Next, a method of using the packaging bag 1 will be described. When taking out the entire amount of the content and taking it, the packaging bag 1 is cut in accordance with the cut position indicating line 6b on the lower side of the intermediate seal portion 3c.
As a result, the outer bag 2 and the inner bag 3 are both opened, so that all the contents 4, 5 can be taken out. Moreover, when taking out a predetermined amount of a part of the content and taking it, the packaging bag 1 is cut according to the cut position indicating line 6a on the upper side of the intermediate seal portion 3c. As a result, the outer bag 2 is opened, but the inner bag 3 remains sealed by the intermediate seal portion 3c and is not opened. Therefore, only the predetermined amount of the contents 4 contained in the outer bag 2 can be taken out.

In the above embodiment, the case where the packaging bag 1 has a two-layer structure of the outer bag 2 and the inner bag 3 has been described, but the present invention is not limited to this case, and a structure of three layers or more is also possible. is there. FIG. 5 is a schematic sectional view showing a packaging bag 10 having a three-layer structure. The packaging bag 10 comprises an outer bag 11, an intermediate bag 12 and an inner bag 13. Each bag 11,1
Both ends of both 2 and 13 are sealed by a seal portion 14 and fixed to each other. The inner bag 13 is formed with a first intermediate seal portion 15, and the intermediate bag 12 is formed with a second intermediate seal portion 16 above the first intermediate seal portion 15. Second intermediate seal part 16
The inner bag 13 may be hermetically sealed. Outer bag
Cut position indicating lines 17a, 17b, 17c are provided on the 11 as cut position indicating means so as to be above and below the first intermediate seal part 15 and the second intermediate seal part 16. Each bag 11,12,1
Each of the three stores a predetermined amount of contents 18a, 18b, 18c.

In the packaging bag 10 having the above structure, by cutting along the uppermost instruction line 17a, only the outer bag 11 can be opened and only the contents 18a therein can be taken out, and the intermediate instruction line 17b
By cutting along the line, the outer bag 11 and the intermediate bag 12 can be opened and the contents 18a, 18b therein can be taken out,
Further, by cutting along the lowermost indicating line 17c, the whole can be opened and all the contents 18a, 18b, 18c can be taken out.

In the above embodiment, the packaging bag of the present invention is used for drug packaging, but the present invention is not limited to this case and can be used for packaging other powdery or granular materials. . For example, in the packaging bag 1 shown in FIG. 1, the outer bag 2 may be filled with coffee and the inner bag 3 may be filled with sugar.

[Effect of device]

As described above, the packaging bag of the present invention has a multi-layer structure having at least an outer bag and an inner bag, and each outer bag and the inner bag contain a predetermined amount of contents, and the inner bag has an intermediate seal portion. Since the outer bag is provided with cutting position indicating means at a position sandwiching the intermediate seal part of the inner bag, the outer bag is cut by the cutting position indicating means on the upper side of the intermediate seal part. Only the bag can be opened and only the contents in it can be taken out. Also, the outer bag and the inner bag can both be opened by cutting the packaging bag according to the cutting position indicating means below the intermediate seal part. It has the effect that the contents of can be taken out.
