And upper and lower auxiliary pieces overlapping with each other.

Here, the size of the hollow portion varies depending on the number of can containers to be inserted and is not limited, but it is common to put three can containers in parallel in two rows. Also, the number of hollows installed in the simple packaging is not particularly limited. For example, when the number of loaded hollows is 6, the width of the tubular body is twice the diameter of the can container. Set to the length of
A partition wall may be provided in the center of the hollow portion. The rigid paper includes, for example, cardboard. Further, the fact that the auxiliary piece is outside the upper and lower tongue pieces means that the auxiliary piece is located outside the upper and lower tongue pieces with respect to the upper plate or the bottom plate of the can container placed in the hollow portion.

When formed in this manner, in the state where the can container is put in the hollow part of the tubular body, the upper and lower tongues provided on the tubular body form the inside of the upper peripheral edge portion and the inner side of the lower peripheral edge portion of the can container. And, respectively, so that the can container has a structure that does not come out of both openings, and
Since the auxiliary piece is interposed like a spring between the inner wall surface of the cylindrical body and the upper and lower tongues, the upper and lower tongues are pressed against the upper plate side or the bottom plate side of the can container. , The upper and lower tongues always keep the can container locked.
For example, an accidental detachment of the can container placed in the hollow portion due to an impact or the like during transportation is prevented.

According to the second aspect of the present invention, the auxiliary piece is formed so that the tip thereof coincides with the tips of the upper and lower tongue pieces. The upper and lower tongues can be pressed against each other to further secure the locked state, and in addition to the locking of the upper and lower tongues, the double locking by the auxiliary piece is performed. The loaded can container can be held more strongly.

Further, according to a third aspect of the present invention, the tip ends of the upper and lower tongue pieces and the respective auxiliary pieces are in a semicircular shape hitting along the upper peripheral edge portion and the lower peripheral edge portion of the can container. Since the can container is formed, the can container is aligned along the upper peripheral edge portion and the lower peripheral edge portion, and the can container can be locked in a more robust state.
