Description

[Detailed Description of the Invention] The present invention relates to a packaging container made of folded paper such as cardboard.

Among the conventional packaging containers made of folded paper, there is a container described in Japanese Utility Model Application Publication No. 75741/1983, which eliminates or reduces the need for foamed polystyrene cushioning material when packaging items. This folded paper packaging container is shown in the upper half perspective view in Fig. 5, the vertical sectional view in Fig. 6,
As shown in the cross-sectional view of FIG.
A pair of buffer side plates 42, 43 each having a V-shaped cross section and supporting the side surfaces of the packaged object 41; Because of the formed structure, it is possible to stably cushion and support the packaged object 41 having a circular side surface, such as a 1.8 bottle, in the vertical and longitudinal directions.
Since the packaged object 48 having square side surfaces such as a rectangular parallelepiped only has its square edges in contact with the buffer side plates, there is a problem in that it tends to shift and cannot be stably buffered and supported.

The object of the present invention is to provide a packaging container made of folded paper that can stably cushion and support not only an object having a circular side surface but also an object having a rectangular side surface such as a rectangular parallelepiped.

Therefore, the present invention has a pair of flat side plates facing each other, and a pair of buffers having an M-shaped cross section that is adjacent to the flat side plates and supports the sides of the packaged object with two pointed heads that protrude inward. a side plate, an upper buffer plate with a V-shaped cross section that supports the upper surface of the object to be packaged with one pointed head that projects inward, and a V-shaped cross section that supports the lower surface of the object to be packaged with one pointed head that projects inward. A flat top plate disposed on the outside of the upper buffer plate so as to connect between the upper ends of the pair of flat side plates, and a flat top plate that connects the lower ends of the pair of flat side plates. The gist is a packaging container made of folded paper, consisting of a buffer plate and a flat bottom plate placed on the outside.

According to the present invention, the object to be packaged is positioned in the vertical direction by the upper and lower buffer plates each having a V-shaped cross section, and the two peaks of each of the pair of buffer side plates each having an M-shaped cross section are used to position the object to be packaged in the vertical direction. By supporting the side surfaces at two points on one side for positioning in the front-rear direction, and by buffering the points and the bending portions of the shock absorbing side plates and the flat side plates by pushing against each other, the It goes without saying that packaged items should be stably cushioned and supported by M-shaped cushioning side plates, and even for items that have square sides, such as rectangular parallelepipeds, the opposing sides should be placed on two sides slightly apart from the square edges. Stable cushioning support to press at a point.

An embodiment of the present invention will be explained below with reference to Figs. 1 to 4. Fig. 1 shows a developed view of a packaging container according to the present invention, which is a container made of folded paper.
Gluing allowance 1, first buffer side plate 2, flat first flat side plate 3, second buffer side plate 4, and second flat side plate 5
are sequentially connected via the broken line 6. A first top plate 7 and a first bottom plate 8 are connected to the upper and lower portions of the first flat side plate 3 via fold lines 9, respectively. Further, a second top plate 10 and a second bottom plate 11 are connected to the second flat side plate 5 in the same manner as described above. Both buffer side plates 2 and 4 have a butterfly-shaped center piece 13 having a small width at the center and a fold line 12 at the center, and a fold line 12 at both left and right ends of the butterfly-shaped central piece 13.
Joint pieces 14 and 15 are connected via 6. Further, hexagonal upper and lower buffer plates 18 and 19 and lower buffer plates 20 and 21 having a fold line 17 in the center are connected to the upper and lower ends of the center piece 13 of each buffer side plate 2 and 4 via a fold line 22. Note that 23 is a closing piece formed at the upper end of the second top plate 10, and 24 is a closing piece hole formed at a fold line between the first flat side plate 3 and the first top plate 7.

Next, to explain how to assemble the container, first, in the developed shape shown in FIG. After bending along
5 to face each other, and the first and second buffer side plates 2 and 4 to face each other. Next, by bending the center piece 13 and joint pieces 14, 15 of each buffer side plate 2, 4 along the fold line 16, and bending the center of the center piece 13 along the fold line 12, each The cross-sectional shape of the buffer side plates 2 and 4 is formed into an M-shape, and the central piece 1
3 and the joint pieces 14, 15 form two pointed parts 25, 26 that protrude inward. Next, by bending both lower buffer plates 20, 21 along the fold line 22 and bending the lower buffer plates 20, 21 along the fold line 17 at the center, the vertical cross-sectional shape is made into a V-shape as shown in Fig. 4. The center fold line portion is formed into a single point 27 that protrudes inward. And both lower buffer plates 2
0 and 21, the bottom plate 8,
11 are bent along the fold line 9, overlapped with each other, and fixed by appropriate means to form the bottom surface of the container. Next, after assembling the upper buffer plates 18 and 19 in the same manner as the lower buffer plates 20 and 21, the first top plate 7 and the second top plate 10 are sequentially bent along the fold line 9 and overlapped,
Insert the closing piece 23 into the hole 24 to complete the assembly.

In the container assembled as described above, the packaged object 28 having square side surfaces, such as a rectangular parallelepiped, is separated from the opposite front and rear sides by the pointed portions 25 and 26 of the first and second buffer side plates 2 and 4 in the front-rear direction a-b. Two points 28 each a little away from the square edge 28c among 28a and 28b
d, 28e are supported in a pushing manner, and the left and right direction c-
d, supported by both flat side plates 3 and 5, and vertically e-f
It is supported by the pointed parts 27, 27 of the upper and lower buffer plates 18, 21. For vibrations in the front-rear direction a-b, the bending portion 2 between the buffer side plates 2, 4 and the flat side plates 3, 5
9 and the peaks 25, 26 of the buffer side plates 2, 4 are pushed against each other to provide a buffer. Also, the vertical direction e-f
The upper and lower buffer plates 18, 19, 2
It is bulged and buffered by the pointed head 27 of 0.21. In addition, for the normal packaged object 28, in order to prevent vibrations in the left and right directions, insert a small piece of cardboard as a cushioning material into the gap 30 between the packaged object 28 and the flat side plates 3, 5, or As shown in FIG.
When the packaged object 28 has no problem with vibration in the left-right direction, for example, when the packaged object itself has a cushioning property in the left-right direction, or when the left and right ends of the packaged object are
It is not necessary to insert a cushioning material into the gap 30 in the case of a packaged item having a deformed square side surface such as a hexagonal shape or a circular side surface that comes into contact with the center piece 13 between 5 and 26.

As is clear from the above description, the present invention consists of a pair of flat side plates that face each other, and a cross section that supports the sides of the packaged item adjacent to the flat side plates with two pointed heads that protrude inward. A pair of M-shaped buffer side plates, an upper buffer plate with a V-shaped cross section that supports the top surface of the packaged object with a single pointed head that projects inward, and a single pointed head that projects the bottom surface of the packaged object inward. A lower buffer plate having a V-shaped cross section and supported by a lower buffer plate, a flat top plate disposed outside the upper buffer plate so as to connect the upper ends of the pair of flat side plates, and a lower edge of the pair of flat side plates. and a flat bottom plate disposed on the outside of the lower buffer plate so as to connect with the lower buffer plate.

Therefore, according to the present invention, it is possible to vertically position the packaged items using the upper and lower buffer plates each having a V-shaped cross section, and the two peaks of each of the pair of buffer side plates each having an M-shaped cross section can position the packaged items in the vertical direction. By supporting the side of the object at two points on one side, it is possible to position the object in the front-back direction, and by the point, the cushioning side plate, and the bent part of the flat side plate pushing against each other and providing cushioning, it has a circular side surface. It goes without saying that the object to be packaged must be stably cushioned and supported by M-shaped shock absorbing side plates, and even for objects to be packaged that have square sides, such as rectangular parallelepipeds, the opposing sides should be placed a little away from the square edges. It can be stably cushioned and supported by pushing at two points. In addition, the pair of buffer side plates and the upper and lower buffer plates can be formed integrally with the flat side plate, top plate, and bottom plate using paper such as corrugated cardboard, so there is no need to dispose of them as with conventional foamed polystyrene cushioning materials, and the number of parts is small. It has excellent effects such as being able to be manufactured at low cost.
