An example of the operation of a box spacer according to the present invention is shown in Figures 6 to 8. According to an embodiment of the present invention, there is provided a packaging system comprising a box spacer as described above. The packaging system according to this description comprises a pair of spacers 1 and a box. According to an embodiment of the invention, the spacers 1 may be formed integrally with the box or may be formed separately from the box and then inserted into the box.

According to an embodiment of the present invention, additional portions may be formed between the second sections 23, 34, 44 and 54 and the attachment portion 80. That is, an extension can be formed as long as it is not critically obstructed by the spacer 1, which is brought into close contact with the inside of the box. The spacer member 1 according to the invention has only the first section and the second section, but the possibility of connecting additional parts, such as third, fourth, etc. sections, as long as they do not significantly interfere with the functions of the first and second wing sections is not ruled out. However, only the first sections and the second sections have been described here for ease of description.

A packaging system comprising a spacer for a box according to the invention comprises two spacers 1 and a box. According to an embodiment of the invention, the spacers 1 may be integrally formed with the housing or may be formed separately from the housing and then inserted into the housing.

The spacers 1 are individually located on two opposite inner sides of the box. The spacers 1 are positioned so that the ends of the wings 20, 30, 40 and 50 are individually in contact with the edges of the inner sides of the housing. Since the second sections 24, 34, 44 and 54 of the wings 20, 30, 40 and 50 are longer than the first sections 22, 32, 42 and 32, respectively. 52, a space is formed between the base 10 and the inside of the box, and gaps are formed from the sides that are in contact with the wings 20, 30, 40 and 30, respectively, from the main folding portions 60 and the partial folding portions 70. 50. Accordingly, the box can be manufactured at low cost and can be carried safely, the impact being prevented by spacers 1, which can be made of the same material as the box.

Connecting portions 111 are formed in the box that can engage the attachment portions 80 of the spacers 1. According to an embodiment of the present invention, the attachment portions 80 may extend from the upper wing 20. The attachment portion 80 may be smaller than the wing widths 20, 30, 40. and 50. Accordingly, the connecting portion 111 can be formed so that the mounting portion 80 can be mounted in a box. According to an embodiment of the present invention, the connecting portion 111 may be a passing surface through which the surface of the box partially passes.

The spacers 1 are located on two sides facing each other from the four inner sides of the box. The spacers 1 are positioned so that the longitudinal free ends Y1, Y2, Y3, and Y4 of the second wing sections 20, 30, 40, respectively. 50 are individually in contact with the edges of the inner sides of the box. Since the spacer 1 according to the present invention conforms to [Formula 1] to [Formula 4], a space is formed between the base 10 and the inside of the box, and the gaps on the sides in contact with the wings 20, 30, 40 and 50 are formed by main folding parts X 1, X ₂ , X 3, and X 4 and partial folding parts Z 1, Z 2, Z 3, and Z 4. Accordingly, the product located between the spacers 1 can be stably supported and protected, and damage to the product due to the impact that can occur when carrying the box can be prevented.

That is, the product to be packaged is placed between the bases 10 of the spacers 1 located on the inside of the box. The product to be packaged may be another box which has rectangular surfaces the same as the shape of the base 10 and which is inserted into the box. The product to be packaged is fixed by the bases 10 of the spacers 1 located on the sides in the box and is spaced from the inside of the box by the wings 20, 30, 40 and 50.

According to the invention, the packaged box can be very easily removed from the box. The upper wing 20 is flat during packaging, as shown in Fig. 10. When the two sides of the upper wing 20 are pulled up, that is, the upper wing 20 is rotated substantially 90 degrees with respect to the main folding portions X 1, X _2. , X ₃ , and X ₄ , as can be seen in Fig. 11, the two spacers 1 move 5 along the inside of the box 1 and extend outwards, so that the product wrapped between the spacers 1 can be easily removed. Accordingly, user comfort can be increased.

It will be apparent to those skilled in the art that the invention described in the foregoing description is not limited to the above embodiments and accompanying drawings, and that changes may be made without departing from the scope and spirit of the disclosure.
