Description

[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a packaging bag capable of taking out contents little by little.
[0002]
[Prior art]
In this type of bag, when the outlet is opened to take out the contents, the contents are often excessively discharged or the amount of the taken out contents is often insufficient. Then, it is difficult to return the excessively discharged contents to the inside of the bag, and after all, it is often processed wastefully. In addition, if the amount of removal is not enough, the removal operation must be repeated many times.
[0003]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a packaging bag that can take out a certain amount of contents at a fixed rate, and can eliminate an excess or deficiency in the amount to be taken out.
[0004]
[Means for Solving the Problems]
In order to solve the above problem, the packaging bag of the present invention has a content storage space 4 between a content storage space 2 and a content outlet 5, and a first portion such as a chuck or the like is provided in the content outlet 5. And a second opening / closing member 13 capable of isolating the contents storage space 2 and the contents holding space 4 is attached inside the opening / closing member 8.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, the bag main body 1 is manufactured using a plastic sheet or the like, and has a content storage space 2 for storing a granular material, a fluid, and the like, and the periphery thereof is sealed. In the drawing, reference numeral 3 indicates a seal portion. The content storage space 2 communicates with a narrow content storage space 4, and the outer end of the content storage space 4 is a content outlet 5. That is, the content storage space 4 is provided between the content storage space 2 and the outlet 5.
[0006]
An opening space 6 is provided outside the outlet 5 so as to communicate with the outlet 5. The opening space 6 is also sealed around, but can be opened by cutting across the bag body 1 from a cut 7 provided at the side edge of the bag body 1.
[0007]
A first opening / closing tool 8 is attached to the outlet 5. For example, a chuck can be used as the first opening / closing tool 8. As shown in FIG. 3, this chuck is constituted by a male member 9 and a female member 10 made of two plastic sheets, and is closed by fitting the protrusion 11 of the male member 9 into the groove 12 of the female member 10. It can be configured to be in an open state by causing the protrusion 11 to escape from the groove 12.
[0008]
Another second opening / closing member 13 is attached inside the first opening / closing member 8 such as the above-mentioned chuck. The second opening / closing member 13 separates the contents storage space 2 and the contents storage space 4 from each other.
[0009]
The second opening / closing member 13 is composed of two plate springs 14 and 15 as shown in FIG. That is, as shown in FIG. 4A, the opening / closing member 13 is assembled such that two leaf springs 14 and 15 are brought into close contact with each other, and the two leaf springs 14 and 15 are brought into contact with no external pressure. In this state, the two plate-shaped springs 14 and 15 are kept in close contact with each other (this state is a closed state), and as shown in FIG. When pressurized in the direction, the two plate-shaped springs 14 and 15 are curved to separate the intermediate portion from each other (this state becomes an open state), and the pressurization is released. In some cases, the two plate-shaped springs 14 and 15 can be restored to the close contact state.
[0010]
As shown in FIG. 4, a convex portion 16 is formed on one of the contact surfaces of the plate springs 14 and 15, and a concave portion 17 is formed on the other contact surface. It is also possible to provide notches 18 and 19 at the intermediate portions in the longitudinal direction to make the two plate-like springs 14 and 15 bend easily. A material having elasticity, for example, plastic or metal can be used for the material of the plate springs 14 and 15.
[0011]
Further, as shown in FIG. 1, holes 20 and 21 having a size into which a finger can be inserted can be formed in the outer seal portion 3 where the second opening / closing member 13 is installed. That is, two fingers are inserted into the holes 20 and 21 so that both ends of the two plate springs 14 and 15 of the second opening / closing member 13 can be pressed. In addition, as shown in FIG. 5, it is also possible to provide notch recessed parts 22 and 23 which open to the side edge of the bag main body 1 instead of the holes 20 and 21.
[0012]
The second opening / closing member 13 is configured as described above so that it can be opened and closed independently of the outside first opening / closing member 8. That is, this is because the inner second opening / closing tool 13 can be opened and closed while the outer first opening / closing tool 8 is closed.
[0013]
In order to take out the contents 24 such as powders and granules from the contents storage space 2, first, the opening space 6 is opened as described above, and then the first opening / closing tool 8 on the outside is closed and the inside is opened. The second opening / closing member 13 is opened. To open the inner second opening / closing member 13, a finger is inserted into the holes 20 and 21 so that both ends of the plate-like springs 14 and 15 of the second opening / closing member 13 are sandwiched between two fingers. The plate-like springs 14 and 15 may be pressed toward the center in the longitudinal direction with the two fingers.
[0014]
In this state, the bag body 1 is turned upside down to drop the contents 24 from the contents storage space 2 to the contents storage space 4 as shown in FIG. When the contents 24 enter the contents storage space 4, the inner second opening / closing member 13 is closed, and the contents 24 in the contents storage space 4 are separated from the contents 24 in the contents storage space 2. In order to close the inner second opening / closing member 13, the pressing operation on the plate-like springs 14, 15 by the finger may be stopped as described above. As a result, the plate springs 14 and 15 are restored and the opening / closing member 13 is automatically closed.
[0015]
Next, while the inner second opening / closing member 13 is closed, the outer first opening / closing member 8 is opened to open the outlet 5. As a result, only a certain amount of the contents 24 in the contents storage space 4 falls outside.
[0016]
【The invention's effect】
In the packaging bag of the present invention, after the contents 24 are once placed in the contents storage space 4 and isolated, only the contents 24 in the contents storage space 4 can be taken out. It is possible to take out the contents 24 by the amount determined, that is, only the contents 24 that have entered the contents storage space 4. Therefore, it is possible to eliminate the excess and deficiency of the amount of the content 24 to be taken out.
