Description

The present invention relates to a container holder, a spout, a spouted bag container supported by the container holder, and a composite container combining a container holder and a spouted bag container.

Pouch containers equipped with a hard plastic dispensing device (also referred to as a "spout") are widely used as refill containers for refilling bottle containers. Products packaged in pouches have the advantage of being available at lower prices than products packaged in bottles. However, when the contents are transferred from the pouch container to a reusable bottle container, there is a risk that bacteria may be mixed in and propagate within the bottle container, which poses a hygiene problem.

When a pouch container is used as it is rather than for refilling, it can stand on its own at the beginning of use, but as the contents decrease, the bag bends and becomes unable to stand on its own. Therefore, container holders (supporting tools) for standing pouch containers upright are disclosed in Patent Documents 1 to 3.

The container holder described in Patent Document 1 and Patent Document 2 has two vertically long rectangular sheets. The left sides of each sheet are connected to each other, the right sides are connected to each other, and a portion of the top side is connected to each other. The upper end of the container holder is provided with an opening through which the pouring tool is inserted. The container holder has a bag-like shape with an open bottom end. When the bag of the pouch container is placed inside the container holder, each sheet deforms so that its cross section has an outwardly convex arc shape. The lower side of each sheet also has an arc shape, and the lower end of the container holder has an elliptical shape (including a substantially elliptical shape). This allows the container holder to stand on its own while supporting the bag upright.

The container holder described in Patent Document 3 has a front part and a back part which are vertically long rectangular sheets. The upper sides of the front part and the back part are connected to each other via the top part. A hole is provided at the top through which the pouring tool of the bag container is inserted. The lower sides of the front part and the back part are connected to each other via the bottom part. The distance between the front part and the back part gradually increases from the upper end toward the lower end. The container holder has an overall wedge shape with a pointed upper end. A bag body is arranged inside the container holder. This allows the container holder to stand on its own while supporting the bag upright.

In the container holder described in Patent Document 1 and Patent Document 2, when a bag is placed inside the container holder, each sheet deforms so that the cross section has an outwardly convex arc shape. However, this container holder is weak against downward pushing force, and for example, when the pump lid member supports a pouch container attached to the dispensing tool and the push-down head is pushed downward, there is a risk that the container holder may be bent. There is. Further, in the container holder, when the contents of the bag decrease, the bulge of each sheet becomes smaller. As a result, the curvature of the arc shape of the lower side of each sheet becomes smaller, and the elliptical shape (minor axis) of the lower end of the container holder becomes smaller. Therefore, the holder becomes difficult to stand on its own while being used.
