Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a form of a cushioning material and a carton case of a carton case for packing products, semi-finished products and the like.

[0002]

[Prior Art]

 A conventional example is shown in a perspective view of FIG. 3A and a sectional view of FIG. In FIG. 3 (a), since the cushioning material is arranged at a predetermined position, the cushioning material is attached to a flat plate of another piece, or as shown in FIG. It was inserted in the slit provided in the. Also, the cushioning material was directly attached to the carton case with an adhesive.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned configuration has problems such as an increase in the number of parts and a lot of man-hours for bonding, and further, if an adhesive is used, it becomes impossible to disassemble and reassemble. was there. Further, the method of inserting the cushioning material into the cut-and-raised part has a problem that the product comes off due to an impact when the product is stored.

[0004]

[Means for Solving the Problems]

 Therefore, in the present invention, an inner flap provided with a protrusion having two folds, a carton case provided with a U-shaped notch on a side contacting with the inner flap, and a carton case inserted into the carton case to store stored items. There is a cushioning material to be fixed, and the cushioning material is provided with a slit into which the protrusion of the inner flap is inserted, and a hole for folding back and inserting the protrusion by the notch is provided on the surface opposite to the slit. It is characterized in that while the cushioning material is wound around the inner flap by a fold, the protruding portion formed by the notch is folded back and fixed in the hole.

[0005]

[Action]

 Therefore, it can be configured only by the carton case and the cushioning material, and the position of the cushioning material in the carton case can be accurately determined and fixed. Furthermore, since it can be disassembled and reassembled, it can be easily stored and the storage space can be reduced.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a cushioning material and a carton case according to the present invention, and FIGS. 2 (a) and 2 (b) are sectional views showing a mounting method thereof. In the figure, a carton case 1 is provided with a protrusion 4 having folds 3a and 3b on an inner flap 2, and U-shaped notches 6 for folding inward are provided on both side surfaces 5 in contact with the inner flap 2. ..

Then, there is a cushioning member 7 which is inserted into the carton case 1 to fix the four corners of the stored item. In this cushioning material, there are slits 9 for inserting the tips of the projections 4 of the inner flaps on the side surfaces 8 facing each other, and on the opposite side, the projections of the U-shaped notches 6 are formed. There is a hole 10 for inserting the part.

In the carton case 1 having the above structure, as shown in the cross-sectional views of FIGS. 2A and 2B, the cushioning material 7 is grasped from both side surfaces, so that the carton case for storing the product is obtained. It can be fixed in place without being disengaged even when it is impacted by 1. Further, the notch 6 of the carton case 1 serves as a grip portion for transportation, but since it can be lifted up together with the cushioning material 7, this grip portion can be significantly reinforced.

[0009]

[Effect of the device]

 According to the present invention, the cushioning material can be fixed without coming off even with a large impact. In addition, it can be easily disassembled and reassembled, reducing the storage space during storage.
