Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bag-like container with a pump used as a container for liquid detergents, cosmetics, seasonings, and the like, and a bag-like container pump to be attached to the bag-like container.
[0002]
[Prior art]
In recent years, bottle containers equipped with a manual pump are widely used as containers for liquid detergents, cosmetics, seasonings, and the like. This type of bottle container with a pump has an advantage that the contents can be extracted without lifting the bottle container, and the contents can be accurately extracted by a desired amount.
The bottle container with a pump is formed of a plastic resin or the like and has a relatively long service life, so that only the contents are provided for refilling. In such a case, as a container for the contents for refilling, a bag-shaped container made of a plastic film that has necessary durability and water resistance and is easy to be disposed of is often used.
[0003]
However, the bag-like container as described above is flexible when the entire container including the extraction port part is flexible, and it is difficult to control the direction and amount of extraction of the contents. There is a possibility of spilling things.
Then, the extraction tool for bag-like containers provided with the hard extraction pipe | tube inserted in the extraction port of a bag-like container, and the fixing member with which the outer peripheral part of an extraction cylinder is mounted is proposed (for example, patent document 1, 2).
According to such an extraction tool, rigidity can be imparted to the extraction port of the bag-like container, so that when the contents are extracted from the bag-like container, the extraction direction and the extraction amount of the contents can be easily controlled. There are advantages.

[Problems to be solved by the invention]
By the way, if you continue to use a bottle container with a pump while refilling the contents, you can easily transfer the contents from the bag-like container to the bottle container by using the extractor as described above, but you can attach the extractor. Since work and removal work increase, there is still a problem that it takes time to refill the contents.
In addition, when the contents are refilled, there is a possibility that different kinds of contents may be mixed due to misidentification of the bottle container. For example, it may be possible to mistakenly transfer a refill shampoo to a rinse container.
[0006]
Therefore, it is proposed that the contents of the bag-like container are directly extracted from the bag-like container and used without being transferred to a bottle container with a pump.
However, when the contents of the bag-like container are directly extracted and used, even if the aforementioned extraction tool is attached, it is necessary to lift and incline the bag-like container when extracting the contents. Not only is it less convenient than a bottle container with a pump, but it also becomes difficult to accurately extract a desired amount of contents.
Moreover, if it is a self-supporting bag-like container, it can be stored in a self-supporting state. However, as shown in Patent Documents 1 and 2, if an extractor is attached to the corner portion of the bag-like container, the left-right balance is achieved. There is also a problem that the bag shape collapses and the bag-like container easily falls.
[0007]
The present invention has been considered in view of the above circumstances, and the contents of the bag-like container can be directly extracted from the bag-like container without being transferred to another container, and can be used.
