[Industrial applications]

 The present invention relates to a container used for liquid contents such as detergents, shampoos and rinses, and more particularly to a refill container that allows easy refilling of contents.

[0002]

[Prior Art]

 In recent years, as consumers have become more aware of the environment, their lifestyles have been revised, and consumer behavior has changed, and consumers are demanding packages that take environmental issues into consideration. From the viewpoints of environmental issues and effective use of resources, plastic product recycling movements and container reuse movements are becoming popular. Against this background of social conditions, it is necessary to use the same container body many times. Demand for refillable containers (containers with refillable contents) is increasing. As a container for refill contents sold separately for this refillable container, a plastic film such as a pillow package (a pillow-shaped bag) or a standing pouch (a self-supporting bag with a bottom gusset) has conventionally been used. Rigid packaging materials such as packaging materials and paper containers (bag-in-box) with a plastic inner bag were used.

[0003]

[Problems to be solved by the device]

 However, in the conventional container for refill contents described above, the contents have to be transferred to the refillable container body, and at the time of this transfer, the contents are spilled out of the container or the hands are soiled. I was afraid to do it. In addition, the entire contents could not be transferred and could remain. For this reason, consumers often dislike this transfer work, and even if they have prepared and placed containers with refillability, they often did not use them. In addition, the conventional refillable container for refilling contents has an unexpectedly high cost during distribution, and the display effect at the time of store display is not good due to the form of the container. The present invention eliminates the inconvenience of using the above-mentioned conventional refillable container, makes it easy to refill the contents, and also provides a container for the refill contents that is well displayed and exhibits an excellent display effect. It is intended to provide an easily refillable container equipped with the container.
