Description

[Detailed description of the invention] The invention consists of an outer box and an inner box made of cardboard or the like, and the outer box and inner box are integrated with a connecting piece,
Relating to a container characterized in that a connecting piece is folded to accommodate an outer box and an inner box, and when in use, the inner box is slid forward by the repulsion of the folded connecting piece to take out the contents from the inner box. It is especially suitable for packaging stick-shaped confectionery, cheese, etc.

Hereinafter, the present invention will be explained in detail based on the embodiments shown in the drawings. First, as shown in FIG. 1, in the present invention, the developed material is a rectangular rear wall 4. The top wall 3 and the bottom wall 5 are connected to the left and right ends of the rectangular rear wall 4 through vertical fold lines, and the side walls 1 are connected to the top and bottom ends of the rectangular rear wall 4 through horizontal fold lines.
0 and 11 are arranged in series, and each side wall 10, 11
The top wall 3 and the bottom wall 5 are connected by a folding piece 19 which is approximately triangular in shape and has a fold line at the center, and further has fold lines m ₁ and m ₂ at the upper and lower ends of the respective side walls 10 and 11, respectively. A folding member having folding pieces 12 and 9 arranged in a row through the top wall 3, having a hole 18 in the free end of the top wall ₃ approximately at the center via the vertical fold line l1, and having folding locking pieces 1 and 20 on three sides of the periphery. The outer box material d formed by connecting the pieces 2 and the front wall 8, which has approximately the same shape and the same area as the rear wall 7, are connected through transverse fold lines n ₁ and n ₂ at the upper and lower ends of the front wall 8, respectively, and the transverse fold lines n ₁ , Approximately trapezoidal side walls 15, 145 with long bases of n ₂ are provided in series, and a glue allowance 16 is provided at the end of one of the side walls 15, 14, and a glue margin 16 is provided at the end of the other side wall (the short side of the trapezoid). The side part) has a protrusion 17 at the same height as the end part, the same width as the front wall, and in the center thereof, which engages with the hole 18 of the folded piece 2 of the outer box material a, and the protrusion 17 is provided through the vertical fold line. A lid piece 21 with an insertion piece 22 at the tip
The bottom wall ₅ of the outer box material a and the front wall 8 of the inner box material b are connected via the fold lines l ₂ and l ₄ , respectively. It is integrally connected to connecting pieces 6 and 7 which are successively provided via a central fold line _l3 .

In addition, in the above description, the side wall 1 of the inner box material b
4 and 15 are trapezoidal, but the oblique sides of the trapezoids may be waveformed as shown in FIG.
Further, the folding locking pieces 20 at the upper and lower ends of the folding piece 2 of the outer box material a are triangular in shape, but this shape is designed to closely abut the oblique sides of the folding pieces 9 and 12. It is sufficient if the oblique side portions of the pieces 9 and 12 and the folding locking piece 20 have complementary shapes.

In addition, the side walls 14 and 1 of the inner box material b may be added as necessary.
A tongue piece 23 may be provided at the side end of the vertical side part 5.

Next, how to assemble the present invention will be explained.

First, the top wall 3, bottom wall 5, side wall 1 of outer box material a
0 and 11 are folded vertically along the respective folding lines, and at the same time folded inward of the folding piece 19 to assemble the container body, and further folding pieces 9 and 11 at the tips of the side walls 10 and 11
12 are each folded inward by approximately 180° via fold lines m ₁ and m ₂ to form a double wall structure, and the folded pieces 2 are
The folding locking pieces 1 and 20 on the three sides of the periphery are folded vertically outward and then folded back approximately 180° inward. At this time, the folding locking piece 20 and the oblique sides of the folded pieces 9 and 12 closely abut each other, and the folded pieces 2, 9 and 12 are fixed, thereby completing the outer box A having a double wall structure. Next, the inner surface of the lower end of the rear wall 13 of the inner box material B and the glue margin 16 are joined together to form a cylindrical body, and the tongue piece 23, the lid piece 21, and the insertion piece 22 are folded in this order and the lid is closed. is completed.

Finally, bend the connecting pieces 6 and 7 outward by approximately 90 degrees along the fold lines 1 ₁ and _{1 2 respectively} .
At the same time, the connecting pieces 6 and 7 are bent and positioned on the inner surface of the bottom wall 5 of the outer box A, as shown in FIGS. 3 and 4.
Store it in outer box A as shown in the figure.

When using the present invention, for example, stick-shaped snacks, cheese, chocolate, etc. are stored in the inner box B, and then stored in the outer box A as described above, and the protrusion 17 of the inner box B and the outer box A are stored. When removing the contents, there is a slight gap between the front wall 8 of the inner box B and the top wall 3 of the outer box A, so use this to open the front wall 8. When pulled forward, it opens as shown in FIG. 3, from which the required amount of contents is taken out, and when closing again, the front wall 8 is pushed back to the state shown in FIG. 2. Furthermore, since the protrusion 17 and the hole 18 are engaged when taking out the contents, the inner box B does not come off more than necessary.

Since the present invention is structured as described above,
It has the following excellent practical effects.

(a) Since the inner box and the outer box are integrally formed, and the inner box is slidably stored within the outer box, it can be easily removed by simply pulling and rotating the inner box.

(b) Due to the repulsion of the connecting plate between the inner box and the outer box, the inner box can be easily taken out, and the inner box is firmly fixed within the outer box when resealing.

C. When taking out the contents, the inner box is rotated so that the opening is slanted, making it easy to take out the contents.

D. All four walls of the outer box have a double structure, making it durable.
