Description

The present invention relates to a bag-in-box. In particular, the present invention relates to a bag-in-box in which the outer box is provided with a handle for grasping with fingers to improve handling convenience.

For example, a so-called bag-in-box container, which has a double layer of an inner bag and an outer box, has a bag, which is a plastic container, inside the outer box that forms the outer shape, and is mainly used for storing liquids. It is widely used as a container for

The characteristics of this type of packaging container are that it is a composite container that combines a plastic container that can store liquids and a recyclable cardboard outer box, and is lightweight, easy to carry, and can be folded, making it ideal for commercial use. It is also used as a liquid container, and also has advantages in separate collection and disposal after use.

This is a big advantage compared to plastic bottles. Therefore, it is widely used in, for example, medicines, detergents, adhesives, alcoholic beverages, beverages, drinking water, and seasonings.

The high impact resistance and compressive strength of the outer box protects the contents from falling and vibration during transportation, and has advantages in ease of stacking and handling for storage. In particular, a rectangular parallelepiped or cubic outer box is space-saving, can be stacked on a pallet, and has excellent transportation and storage efficiency.

Moreover, the plastic inner bag is effective in preventing liquid leakage, preventing deterioration of the contents, and suppressing the influence of the environment on the contents. By connecting a spout to this plastic container, it is possible to pour out the contents from the outside of the outer box.

However, conventional bag-in-boxes have generally been installed on a desk or stand, and the liquid inside is poured out through a spout due to the pressure of the liquid contained therein.

For example, if the liquid content is a beverage, there is a method in which the beverage can be poured out by opening a cock attached to the spout. However, the problem with opening and closing the cock is that it is extremely difficult to adjust and requires skill.

Furthermore, in other cases, the outer box may be handled by directly holding it, and in that case, it is often slippery and there are problems with workability.

Patent Document 1 also describes an outer box with a handle, but the handle has a complicated structure and is difficult to manufacture and assemble, and the shape of the handle does not change due to the provision of the handle. The top surface was sloped, making it unsuitable for stacking.
