Description

[Detailed Description of the Invention] The present invention relates to a roll-shaped product in which a wide aluminum foil is wound in a long length around a core shaft, that is, a packaging box for a wound roll of aluminum foil.

Wide aluminum foil produced at a manufacturing factory is packaged and shipped in the form of a long roll wound around a cylindrical core.

Conventional packaging boxes used for this type of shipping are generally made with the bottom wall and all four surrounding walls integrally joined together inseparably, with the primary purpose of protecting the aluminum foil. The reality is that no consideration has been given to improving the work efficiency of opening boxes and adding more products, and furthermore, there is no consideration given to the repeated use of packaging boxes or the ease of transporting empty packaging boxes. However, it does not have a completely satisfactory structure.

This invention not only protects the aluminum foil that is stored, but also makes it easy to open the box and rub out the product, and there is no risk of damaging the product when storing or taking it out. To provide a packaging box for a rolled product whose height can be reduced by horizontally laying one part down and which can be returned and transported in a compact form.

Below, we will explain the drawings showing the embodiment of the present invention.
, 3 are both side walls, 4 is a bottom plate, 5 is a lid plate, 6 is an aluminum foil winding roll body, and 7 is a core shaft of the roll body 6, and the roll body 6 is inside the packaging box main body 1. Both ends of the core shaft 7 are supported, and the core shaft 7 is stored in a floating state inside the box and packed with the lid closed.

The present invention includes buttons on such a packaging box, as shown in exploded view in FIG.
, 3 are separable, and at least the front and rear walls 2, 2 have a double structure consisting of an inner wall button and an outer wall. A support recess for supporting the lower circumferential surface of the core shaft 7 of the winding roll body 6 with a dimension larger than the winding radius of the winding roll body 6 from the bottom plate 4 of the inner wall 2A of the half portion 2-1. 8, 8, and a presser concavity 9 for pressing the upper peripheral surface of the core shaft 7 of the Ronil body 6 by rolling it up on the lower edge of the inner wall 2B of the upper half portion of the front and rear walls 2, 2,
9 are formed from the upper end of the inner wall 2B with a dog dimension apart from the radius of the wound aluminum foil of the winding roll body 6, and furthermore, the inner wall 2B and the outer wall 2D of the upper half portion 2-2 of the front and rear walls 2, 2 are formed.
A strut member 11° 11 is provided between the front and rear walls 2, 2 to be inserted into the gap 10 between the two inner walls and the outer wall 2C of the lower half portion 2-1 of the front and rear walls 2, 2. By lowering the upper half portion 2-2 of the front and rear walls 2, 2 from above the lower half portion 2-1, the strut members 11.11 are moved between the inner and outer walls 2A, 2C of the lower half portion 2-1. At the same time, the core axis I of the winding roll body 6 is regulated in an immovable state by the support recess 8°8 and the presser recesses 9, 9, and the front and rear walls 2° By pulling out the upper half portion 2-2 of 2 upwardly, the core shaft 7 of the housed wind-up roll body 6 is exposed.

Furthermore, as shown in the figure, the lower half portion 2-1 of the front and rear walls 2, 2
The height of the outer wall 2C is smaller than that of the inner wall 2A, and the height of the outer wall 2D is larger than that of the inner wall 2B for the upper half part 2-2, so that when the upper half part 2-2 is separated, the lower half part The support recesses 8, 8 of 2-1 are exposed from the outer wall 2C,
This also exposes the lower part of the core shaft 7 so that a lifting belt or wire can be easily wrapped around it.

Note that there is no particular limitation on the means for making the upper half portion 3-2 of the two divided side walls 3, 3 detachable from the lower half portion 3-1, but for example, as shown in the figure,
On both sides of the inner surface of the upper half portion 3-2, the front and rear walls 2,
Vertical beam 12 extending vertically along the inside of the two people

It is preferable to press the button so that it can be held in place so that it can be joined in an inverted state.

Further, as can be understood from FIG. 2, the left and right end surfaces of the front and rear walls 2, 2 of the double structure described above are located on the inner surfaces of the above-mentioned both side walls 3, 3. Upper half part 2-
2 can be stored on the bottom plate 4 during empty box transportation.

As described above, in the packaging/box of the aluminum foil winding roll according to the present invention, the upper halves 2-2 and 3-2 of the main body 10 of the packaging box 10, the front and rear walls 2, 2, and the side walls 3, 3, respectively, can be separated. Therefore, the winding roll body 6 is carried in with the upper half of the packaging box main body 1 removed and supported on the support recesses 8, 8 at the upper end of the lower half, or the support recess 8 is , 8, and the upper half does not get in the way at all, so it is easy to carry in and out, and the aluminum foil does not collide or come into contact with the upper half and be damaged when carrying in or out. The work of storing and taking out the winding roll body 6 is easy, and there is no risk of damaging the product when taking it out.

In addition, by storing the recruited upper half in the lower half, the bulk of the empty box during transport can be halved.

Further, the front and rear walls 2゜2 have a double structure consisting of an inner wall button and an outer wall, and a support recess 8 is provided at the upper edge of the inner wall 2A of the lower half portion 2-1 of the front and rear walls 2,2, and the upper half portion 2. Since the presser recess 9 is formed at the lower edge of the inner wall 2B of -2, the position of the core axis I of the housed winding roll body 6 is firmly regulated, and the winding roll body 6 is not held in the box. It can be stored immovably in the hollow of the
The aluminum foil can be transported reliably without being damaged.

Further, the height of the outer wall 2C is made smaller than the inner wall 2A of the lower half portion 2-1 of the front and rear walls 2, 2, and the height of the outer wall 2D is made larger than the inner wall 2B of the upper half portion 2-2. Because there are
When the upper half part 2-2 is separated, the support recesses 8, 8 of the lower half part 2-1 are exposed beyond the upper edge of its outer wall 2C, so the lower part of the core shaft 7 of the rolled-up sheet roll body 6 is also exposed. Therefore, it is easy to wrap a lifting belt or wire around this core shaft 7, and the work of storing or taking out the winding roll body 6 becomes extremely easy. Accidents such as damage to surfaces can be prevented from occurring.

Furthermore, there is a gap between the inner wall 2B and the outer wall 2D of the upper half portion 2-2 of the front and rear walls 2, 2, and between the two inner walls and the outer wall 2C of the lower half portion 2-1 of the front and rear walls 2, 2. Strut material 1 inserted into 10
1, the support member 11 can be easily inserted into the gap between the lower half part 2-1 and the upper half part 2-2.
can be jointed and erected on the lower half part 2-1, and while the upper half part and the lower half part can be separated to obtain the above-mentioned effect, they can be integrally connected in the joined state, and the winding roll body 6 can be It has many beneficial effects as a transport link for aluminum foil take-up rolls, such as being able to store and hold the aluminum foil in a safe manner.
