Abstract

PURPOSE:To obtain a liquid containing bag wherein liquid in the bag can be taken out to the end while a stable flow is maintained. CONSTITUTION:When a bag 1 made of synthetic resin for housing inside liquid such as cleaning solution is stood, a liquid outlet port 3 and an air port 4 are formed to protrude on a part of a heat sealed part 2 at the upper end of the bag 1. When the heat sealed part 2 at the upper end of the bag 1 is cut across the liquid outlet port 3 and the air port 4 to put the liquid into a refill container, liquid flowing out of the liquid outlet port 3 is substituted by air entering from the air port 4, so that inner faces at the liquid outlet port 3 may not be attached to each other but the liquid in the bag 1 can be taken out to the end while a stable flow is maintained.

Description

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 inside the bag, Even if the inflow (replacement) of air into the bag is insufficient, the liquid flows out vigorously from the liquid outlet, but when 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 liquid came to flow out from several narrow mouths in a state where the directions were not fixed because the comrades were in close contact with each other.

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 capable of taking out the liquid in the bag while maintaining a stable flow until the end.

[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 take-out port and an air port are formed so as to protrude from a part of the heat-sealing part at the upper end of the bag, and the heat-sealing part at the upper end of the bag is cut across the liquid take-out port and the air port. Is.

[0006]

With the above construction, when the heat seal portion at the upper end of the bag is cut across the liquid outlet and the air port to take out the liquid from the bag and refill it into the transfer container, the liquid and air coming out of the liquid outlet It is possible to take out the liquid in the bag with a stable flow until the end without the air entering from the mouth being replaced and the inner surfaces of the liquid taking-out port being in close contact with each other.

[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. More specifically, the liquid outlet 3 is a bag 1.
The air port 4 is formed on one side of the bag 1 close to the other side of the bag 1, and the liquid take-out port 3 is inclined so that its tip is directed to the corner of the one side of the bag 1. Is the liquid outlet 3
The tip is inclined at an angle slightly larger than the inclination angle of 1 so that the front end faces the one side of the bag 1.

A cut line 5 is drawn on the heat seal portion 2 at the upper end of the bag 1 so as to cross the liquid outlet 3 and the air port 4, and liquid is obtained by cutting along the cut line 5 with scissors or the like. Both the outlet 3 and the air port 4 are opened.

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 in the transfer container 6, 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. Further, since the air outlet 4 is inclined in the same direction as the liquid outlet 3, if the bag 1 is strongly grasped while pouring the liquid from the liquid outlet 3 into the transfer container 6, the air outlet 4 will come out. It is possible to prevent the liquid from splashing, but the liquid from splashing in the direction in which it merges with the liquid from the liquid outlet 3, that is, toward the mouth of the transfer container 6, and splashing to the outside of the transfer container 6.

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 outlet 3 is inclined so that its tip faces the corner of one side of the bag 1, and the air port 4 is slightly sharper than the inclination angle of the liquid outlet 3 and its tip is on the side of the bag 1. Although it is inclined so as to face in the direction, the liquid outlet 3 and the air port 4 may be directed right above or in the opposite directions when the bag 1 is upright. Further, the bag 1 may be made of aluminum foil having a synthetic resin film mounted on the inner surface.

[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.
