Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid storage bag for storing liquid such as detergent.

[0002]

2. Description of the Related Art Conventionally, detergents and the like used at home are packed in synthetic resin containers for sale. For example, if the detergent in the container is exhausted, it will be refilled in a synthetic resin bag. I bought a detergent and refilled this refill detergent in an empty container.

[0003]

Most of the conventionally known synthetic resin bags containing a liquid such as this kind of refilling detergent have a rectangular shape when viewed from the front, and the liquid is taken out of the bag and emptied. When refilling into the container, one corner of the top of the bag is cut with scissors to form a liquid outlet, and then the bag is held in the hand when working, and when there is a large amount of liquid in the bag, Even if the inflow (replacement) of air into the bag is insufficient, the liquid flows out vigorously from the liquid outlet, but if the amount of liquid in the bag is too small, the amount of air in the bag is insufficient and the inner surface of the liquid outlet There was a problem that the comrades came into close contact with each other, and liquid flowed out from several narrow mouths in an undetermined direction and spilled out of the container.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a liquid storage bag which allows the liquid in the bag to be taken out without spilling while maintaining a stable flow until the end. is there.

[0005]

In order to solve the above problems, the present invention relates to a liquid storage bag made of synthetic resin or the like in which a liquid such as detergent is stored. A liquid outlet and an air port are formed so as to project into a part of the heat-sealed portion at the upper end of the bag, and a hole is formed by hollowing the heat-sealed portion between the liquid outlet and the air port, The heat-sealing portion at the upper end of the bag is configured to be cut across the liquid outlet, the air port and the hole.

[0006]

With the above structure, when the heat-sealing portion at the upper end of the bag is cut across the liquid outlet and the air port to transfer the liquid from the bag into the container for refilling, the liquid and the air outlet from the liquid outlet are used. It is possible to take out the liquid in the bag with a stable flow until the end without the air entering is replaced and the inner surfaces of the liquid take-out port are not in close contact with each other. Further, the liquid outlet can be made small in width so that it can be inserted into the mouth of the transfer container, and the liquid can be refilled without spilling out of the transfer container.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 3, reference numeral 1 denotes a self-supporting synthetic resin bag called a so-called stand pack in which a liquid such as refilling detergent is stored, and the bag 1 has a rectangular shape when viewed from the front in a standing state. , The surroundings are closed by heat sealing. 2 is the heat seal part. 3 and 4 are liquid outlets and air ports formed at the upper end of the bag 1 in the upright state.
Is formed so as to project to a part of the heat seal part 2 at the upper end of the. Reference numeral 5 is a hole formed by hollowing the heat seal portion 2 between the liquid outlet 3 and the air outlet 4.

More specifically, the liquid outlet 3 is formed on one side of the bag 1, and the air port 4 is formed on the other side of the bag 1. 6 is a cut line that is drawn so as to cross the liquid take-out port 3, the air port 4, and the hole 5 in the heat-sealed portion 2 at the upper end of the bag 1, and by cutting along the cut line 6 with scissors or the like. The liquid outlet 3 and the air port 4 are both open.

In the above structure, when the liquid is taken out from the bag 1 containing a liquid such as detergent and the liquid is refilled into the transfer container 7, the liquid coming out of the liquid taking-out port 3 and the air coming in from the air port 4 are replaced. , Liquid outlet 3
Bag 1 without the inner surface of each other sticking together
The liquid inside can be taken out while maintaining a stable flow until the end. At this time, the liquid take-out port 3 has a small width so that it can be inserted into the inside of the mouth portion 7a of the transfer container 7, and the liquid can be refilled without spilling out of the transfer container 7.

In the embodiment shown in the drawings, the bag 1
Although it has a so-called stand pack shape with a swelled lower end, it may be formed so that four edges are heat-sealed and the edge is linear over the entire circumference. Further, the liquid take-out port 3 is directed right above in the state where the bag 1 is erected, and the air port 4 is inclined so that the tip is directed toward one side of the bag 1, but the bag 1 is erected. In this state, both the liquid outlet 3 and the air port 4 may be directed right above or opposite to each other.

[0011]

As described above, according to the present invention, when the liquid is taken out from the bag and is refilled in the transfer container, the liquid coming out of the liquid taking-out port and the air coming in from the air port are replaced, and the inner surface of the liquid taking-out port is replaced. The liquid in the bag can be taken out keeping the stable flow until the end without the mutual contact. Further, the liquid outlet can be made small in width so that it can be inserted into the mouth of the transfer container, and the liquid can be refilled without spilling out of the transfer container.

Claims (1)

[Claims] 1. A liquid storage bag made of a synthetic resin or the like in which a liquid such as a detergent is stored. The liquid storage bag protrudes to a part of a heat-sealed portion at an upper end of the bag when the bag is erected. While forming a liquid outlet and an air port, a hole is formed by penetrating the heat-sealed portion between the liquid outlet and the air port, and the heat-sealed portion at the upper end of the bag is connected to the liquid outlet, the air port, and the air port. A bag for storing liquid, characterized in that the bag is cut across the hole.
