Description

[Detailed description of the invention] [Field of industrial application] The present invention is a method for dispensing the liquid filled in each chamber from a bag separated into two chambers by a partition film through a single spout. This invention relates to a bag with a spout that allows pouring without mixing.

[Prior art and its problems]

When installing a spout in a bag that is separated into two compartments by a partition film, for example,
As shown in Japanese Patent No. 94754, a structure in which a spout is provided in the film outside each chamber is common.

In this way, two spouts are provided, and each
Although it is possible to pour the contents into the chamber and pour out the contents without mixing the contents, it is impossible to manufacture the bag with a structure in which the bag is simply partitioned with a partition film to provide a spout, and the process is complicated. It was something that would become something.

[Problem to be solved]

To provide a bag with a pouring spout in which two chambers are formed simply by partitioning the bag with a single partition film and having two chambers provided with one pouring spout.

[Means for solving problems]

It has a double structure of an inner cylinder and an outer cylinder that are integrated at a partial connection part, the inner cylinder is longer than the outer cylinder, and the spout with a fixed part at the lower end of the inner cylinder and outer cylinder is a middle partition. This problem was solved by fixing the fixing part of the inner tube to the partition film of the bag and the fixing part of the outer tube to the outer film of the bag, which has two chambers formed by film.

[Effect]

The spout has a double structure of an inner tube and an outer tube, and the inner tube is longer than the outer tube, and is attached to the bag's partition film and outer film, respectively, so you can pour into the inner tube and outer tube separately. By fitting the removable nozzle, the contents can be injected into the two chambers without mixing, and can be poured out from the two chambers without mixing.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a partially broken explanatory diagram showing a partial cutaway of a bag in which a partition film 3 of the same size as the outer films is provided between the outer films 1 and 2, and two chambers A and B are sealed around the outer film by heat sealing. Dual structure of inner cylinder 6 and outer cylinder 7 integrated at connecting part 5, inner cylinder 6
is longer than the outer cylinder 7, and has a spout 10 with circular fixing parts 8 and 9 provided at the lower ends of the inner cylinder 6 and the outer cylinder 7, respectively, with the fixing part 8 inside the partition film 3 and the fixing part 9 This is a bag with a spout fixed to the inside of an outer film 1 by heat sealing.

Details of the spout 10 of the bag shown in FIG.
As shown in the figure, its structure is as described above.

As mentioned above, the inner cylinder 6 of the spout 10 is longer than the outer cylinder 7, but the inner cylinder 6 only needs to extend downward by at least the length.

Furthermore, if the inner tube 6 extends slightly upward as well as downward from the outer tube 7, it will be easier to fit the nozzle used when pouring out the contents.

The nozzle used for pouring out the contents may have a double structure and be fitted into the inner cylinder 6 and outer cylinder 7 of the spout, respectively.For example, as shown in FIG. and an inner wall 21 that is concentric with the outer wall 20. The outer wall 20 and the inner wall 21 are integrated by the top plate 22 of the outer wall 20, and the inner wall 21 extends outward from the top plate 22 and is connected to one place on the outer wall 20. The nozzle has a structure in which a cylinder 23 is provided.

When pouring in and out the contents of the bag with the above structure, instead of pouring in and out two different contents at the same time, for example, after using the developer in chamber A, such as developer, in the developing machine, the used waste liquid is discarded. It is also possible to collect it in room B.

〔effect〕

Since the bag of the present invention has the above-mentioned configuration, even though it is a two-chamber bag, it is possible to pour out two contents using one spout without mixing them, and the exterior body that houses the bag of the present invention requires only one hole and is easy to assemble for use.

Furthermore, since two chambers can be formed in the bag by simply providing one partition film between the outer films, the structure of the partition film, which was conventionally complicated to provide two spouts, can be simplified.

Claims (1)

[Scope of utility model registration request] It has a double structure of an inner cylinder and an outer cylinder that are integrated by a partial connection part, the inner cylinder is longer than the outer cylinder, and a spout with a fixing part at the lower end of the inner cylinder and outer cylinder is installed in the middle. A bag with a pouring spout formed by fixing a fixing part of an inner cylinder to the partition film of the bag and fixing a fixing part of the outer cylinder to an outer film of the bag, which forms two chambers with a partition film.
