Description

[Detailed Description of the Invention] The present invention relates to the structure of an aluminum foil package wound in a roll around a cylindrical core.

Conventionally, rolled aluminum foil wound around a cylindrical core is generally shipped and sold in a long and narrow carton case, but in the case of a general household package with a capacity of about 10 to 20 m, Since it is relatively lightweight, it is sufficient to hold both ends of the cylindrical core with a single perforated piece, and there is little damage to the packaging box, and even if it is slightly damaged, it will not damage the rolled aluminum foil that is inside. The impact is small.

However, if a roll of long aluminum foil wound around 100 to 200 m long for commercial use is stored in a carton case in the same manner as for general household use, the roll itself has a considerable weight. As a result, the perforated pieces supporting both ends of the cylindrical core were broken or damaged due to impacts during transportation, disrupting the support structure within the case, and furthermore, the carton case was damaged during transportation and handling. In this case, there is an inconvenience that the aluminum foil may be hit and scratched.

This inconvenience becomes particularly problematic when it occurs at both end edges of the rolled aluminum foil, resulting in an obstruction to smooth unwinding during use.

The present invention relates to the structure of a packaging body that improves the above-mentioned drawbacks in a rolled aluminum foil packaging box having a length of 100 to 200 m or more, and an embodiment thereof is shown in the drawings. As shown in FIG. An inner box 6 is formed which includes an end wall surface 5 having a support hole 4 and has a size that fits exactly into the inner wall of the outer case 9, and houses a rolled aluminum foil 7 in the inner box 6. Both ends of the cylindrical core 8 of 7 are supported by the support holes 4.4 of the overlapping walls of the at least two end walls 5, 5, so that the aluminum foil 7 is substantially held against the inner surface of the inner box 6. The aluminum foil 7 is held in a non-contact state, and the aluminum foil 7 is housed in an outer case 9 together with the inner box 6.

Although the structure of the outer case 9 is not particularly limited, it has a volume that can accommodate the above-mentioned inner box 6 so that it does not move loosely, and a cutting saw blade 10 is provided at the free edge of the opening. A carton case having an integrally formed lid portion 11 that can be opened and closed is suitable.

In addition, the inner box 6 is preferably made of corrugated paper that is slightly thinner than a normal corrugated sheet, and as shown in FIG. An end wall surface 5 provided with a support hole 4 is provided at the end wall surface 5, and both ends of the core body 8 of the rolled aluminum foil 7 are provided with three end wall surfaces 5, respectively.
, 5.5 The aluminum foil 7 will be more robust if it is supported by the overlapping wall of 5.
can be retained.

As described above, the roll-shaped aluminum foil package according to the present invention is made of a lightweight paper material with high rigidity, and has at least three wall surfaces, the bottom surface 1 and both side surfaces 2 and 3, and at least two of the three wall surfaces that are extended and folded. It is provided with an end wall surface 5 having a support hole 4 in the central part of the curved part, and an exterior case 9.
An inner box 6 having a size that exactly fits into the inner wall is housed in an outer case 9, and the support holes 4 in the at least two end wall surfaces 5 of the inner box 6 allow both ends of the cylindrical core 8 of the rolled aluminum foil 7 to be attached. is supported, and the rolled aluminum foil 7 is accommodated in a substantially non-contact state with the inner surface of the inner box 6, and the supporting parts at both ends of the cylindrical core body 8 hold the rolled aluminum foil 7. Since it is formed by the end wall surface of the inner box 6 that is overlapped more than twice and that fits exactly into the outer case 9, the end wall surface is deformed by fitting the inner box 6 into the outer case 9. The end walls are double or triple layered, which increases the support strength and allows the package to maintain its roll shape even if it is subjected to some shock or vibration during handling. The accommodation posture of the aluminum foil 7 is not disturbed, and the inner box 6 protects against external force, thereby avoiding an accident in which the aluminum foil is damaged.

Moreover, by setting the rolled aluminum foil 7 in the inner box 6 and inserting this inner box 6 into the outer case 9, the rolled aluminum foil 7 can be easily attached and is securely supported by the plurality of end walls 5. can.

Furthermore, when in use, the above-mentioned support hole 4 exerts a bearing function, and as soon as the lid is opened, the bond can be pulled out smoothly as before, making it especially suitable for heavy rolls wrapped with long aluminum foil. It has a remarkable effect.
