Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention places a product to be packaged on a shallow box-shaped bottom frame made of corrugated cardboard and having a rising part on the periphery, and the lower end is released. The present invention relates to a packaging device in which the above packaging box is covered so as to cover the article to be packaged, and the lower portion of the packaging box is fitted to the outer periphery of the rising portion.

(Prior Art) Conventionally, in this type of packaging device, the bottom frame has a tongue piece formed at one end of the adjacent rising portions, and the tongue piece is overlapped with the other rising portion and fixed by a staple. Is formed into a shallow container shape, the article to be packaged is placed on this bottom frame via a buffer, and the lower part of the packaging box is covered by covering the article to be packaged with the packaging box whose lower end is open. It is adapted to be fitted around the outer periphery of the rising portion.

(Problems to be Solved by the Invention) In the above-mentioned conventional device, the rising portion is bent upward at a right angle to form the bottom frame, and the tongue piece and the rising portion are fixed with a stopper such as a staple. However, since the corrugated cardboard is compressed and crushed at the part fixed with the staple, it becomes easy to bend, and for this reason, the part of the rising part except the corner parts at both ends returns by springback and goes outside. There is a tendency to swell, for this reason, when fitting the lower part of the packaging box, there is a situation that the lower end of the packaging box is caught in a part of the rising part other than near the corner parts of both ends, and it is difficult to work, It is also practiced to make the packaging box a little larger so that it will not get caught, but if this is done, dust will enter the interior of the packaging box through the gaps and stain the items to be packaged inside, or treat it as a load. There was a defect that the packaging box was sometimes deformed by the amount corresponding to the gap.

Therefore, an object of the present invention is to perform a packaging operation easily, and to prevent dust from entering the inside of the packaging box to stain the object to be packaged or prevent the packaging box from being deformed during handling. To provide.

[Means for Solving the Problem] (Means for Solving the Problem) The present invention forms a shallow box-shaped bottom frame having a rising portion in the peripheral portion by bending the outer periphery of a corrugated board material upward, and this bottom An article to be packaged is placed on a frame via a cushioning body, a packaging box having an open lower end is covered so as to cover the article to be packaged, and the lower part of the packaging box is fitted to the outer periphery of the rising portion. , Adjacent corners of the rising portion, the corner portion of the rising portion is 90 ° to the bottom surface of the bottom frame.
It is characterized in that they are fixed to each other by a fastener so as to form an angle of less than and an escape recess is provided in a portion corresponding to the fastener.

(Operation) With the means described above, when the packaging box is covered with the bottom frame without making the packaging box large, it is possible to prevent the rising portion from being caught in a portion other than the vicinity of the corner portion of the measuring bridge, and therefore,
The packaging work is easy, and moreover, it is possible to prevent dust from entering through the gap to contaminate the article to be packaged, or to prevent the packaging box from being deformed when handling the load.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. A corrugated board material 1 is formed as shown in the development view of FIG. 2, and folds 1a to 1h are formed in this. Fold
1e and 1f are set to an appropriate angle of less than 90 ° to folds 1b and 1d, and folds 1g and 1f are also set to an angle of less than 90 ° to folds 1b and 1d. The folds 1a to 1d are respectively bent upward to form the rising portions 2 to 5, and the folds 1e to 1h are bent to form the tongue pieces 6 to 9. The tongues 6 and 7 are superposed on the rising portion 4 and are connected and fixed to each other by a stopper, such as a staple 10, and the tongues 8 and 9 are superposed on the rising portion 5 and are also connected and fixed to each other by the staple 10, to form a shallow container shape. Bottom frame
11 are composed. This bottom frame 11 has folds 1e and 1g set at an angle of less than 90 ° with respect to fold 1b, and folds 1f and 1h.
Is set at an angle of less than 90 ° with respect to the fold line 1d, so that the rising portion 4 has a bottom frame near the corners at both ends thereof.
It presents an angle of less than 90 ° to the bottom surface of 11, and
The rising portion 5 makes an angle of less than 90 ° with the bottom surface of the bottom frame 11 in the vicinity of the corner portions at both ends thereof. This bottom frame 11
A wooden frame member 12 for reinforcement is placed on the peripheral portion and the central portion of the inner bottom surface of the. Styrofoam cushions 13 are provided along the inner surfaces of the rising portions 2 and 3, and escape recesses 13a are provided at both ends of the shock absorbers 13 at the portions corresponding to the staples 10. Convex part 13 in the vicinity
Although the b is provided, the tongues 6 to 9 are provided with a fitting hole 14 into which the convex portion 13b is fitted and which fixes the cushioning body 13 to the bottom frame 11.

The object to be packaged 15 is placed on the buffer body 13 described above, the packaging box 16 is covered so as to cover the object to be packaged 15, and the lower end thereof is fitted around the rising portions 2 to 5. .

In the above-mentioned embodiment, the both ends of the rising portions 4 and 5 are bottom frames.
Since the corrugated cardboard is formed at an appropriate angle of less than 90 ° with respect to the bottom surface of 11, the corrugated cardboard is crushed at the portion fixed with the staple 10, and the corrugated cardboard bends at that portion and the corners of the rising portions 4 and 5 Even if a portion other than is returned by spring back in the direction of the arrow a, the angle between the portion and the bottom surface of the bottom frame 11 does not exceed 90 ° as in the conventional case. Further, since the buffer body 13 is provided with an escape recess 13a for escaping the staple 10 at a portion corresponding to the staple 10, even when the buffer body 13 is fitted and fixed to the bottom frame 11, both corners of the rising portions 4 and 5 are provided. Can be no more than 90 °. Therefore, if the inner circumference of the lower end of the packaging box 16 is formed to match the outer circumference of the lower portion of the bottom frame 11,
The 16 can be fitted into the bottom frame 11 smoothly.

[Effects of the Invention] As is apparent from the above description, the present invention forms a shallow box-shaped bottom frame having a rising portion in the peripheral portion by bending the outer periphery of a corrugated board material upward, and this bottom is formed. In the one in which the article to be packaged is placed on the frame via the cushioning body, the packaging box having an open lower end is covered to cover the article to be packaged, and the lower portion of the packaging box is fitted to the outer periphery of the rising portion. , The adjacent corner portions of the rising portions are fixed to each other with a metal stopper so that the vicinity of the corner portions of the rising portions forms an appropriate angle of less than 90 ° with respect to the bottom surface of the bottom frame, and the buffer body is fixed. Since a relief recess is formed in a portion corresponding to the metal fitting, when the packaging box is put on the bottom frame without enlarging the packaging box, the lower end of the packaging box has a lower end of the rising portion. Prevents getting caught in parts other than near corners Can, therefore, has a simple task of packaging, moreover, exhibits or stain the objects to be packaged from entering the dust from the gap, or, an excellent effect that its packaging at the factory handling can be prevented from being deformed.
