2. Description of the Related Art Conventionally, as a protective material for mitigating impact on bottles when packaging sake bottles or Western sake bottles, shock-absorbing pad materials made of foamed synthetic resin such as styrofoam have been manufactured. There are known examples. However, such cushioning pad material made of foamed synthetic resin, after transporting the bottle, can only be disposed of or incinerated, and when it is disposed, it is hardly decomposed spontaneously. In the case of generating toxic gas etc.,
There was a problem that each had an adverse effect on the environment. In addition, the above-mentioned protective material is formed by sandwiching a corrugated corrugated cardboard or a frame-shaped body such as a honeycomb layer between two upper and lower cardboards (hereinafter referred to as “reinforced corrugated cardboard”).

2b and the diameter of each recess 22a, 22b is set to be slightly smaller than the diameter of the bottle B to be packed, each recess 22a, 22b
The bottom portion of the bottle B can be tightly pushed and fixed into the inside 22b. Further, since the frame-like body compression portions 25a and 25b immediately below the recesses 22a and 22b have a structure like a spring, it is possible to elastically support the bottle B, and thereby, the bottle that is the object to be packed.

Next, with reference to FIGS. 5 to 7, the contents of the method for producing the corrugated board protective material by the corrugated board processing apparatus 31 will be described. First, as shown in FIG. 5, a pressing force (not shown) driven by a hydraulic pressing device or an electric motor is used to generate a pressing force P2, which is transmitted to the corrugated paperboard cutter 32 by a pressing rod or the like. The pressing device (not shown) driven by a hydraulic pressing device, an electric motor, or the like corresponds to pressing means.

When the above-mentioned pressing force P2 is applied, the corrugated paperboard cutter 32 is brought into contact with the first surface thick paper 11 on the surface of the corrugated paper to be processed 10 and pressed by the predetermined force P2. By this predetermined force P2, first, the saw blades 34b1 and 34b of the bottle body
b2 and 34b3 bite into the first surface cardboard 11 on the surface of the corrugated cardboard 10 to be processed, and then the saw blade 34a at the bottle neck bites into the first surface cardboard 11 on the surface of the corrugated cardboard 10 to be processed,
Further, the saw blades 34c1 and 34c2 at the bottom of the bottle bite into the first surface cardboard 11 on the surface of the corrugated paper 10 to be processed. As a result, the first front side thick paper 11 is shown in FIG.

This concave portion has a flat bottom surface shape at the bottle neck portion, has a bottom surface shape such that the center portion is recessed in a substantially arc shape at the bottle bottom portion and the both side portions are flat, and the bottle barrel portion is substantially the same as the body portion of the bottle. Similar opening 5
It is a concave portion having 6.

Therefore, the corrugated paperboard protective material 51 as shown in FIG. 7 is manufactured. This corrugated paper protective material 5
1 can be protected with the bottle lying sideways.
At this time, since the frame-shaped body compression portions 55a and 55c immediately below the bottle neck recessed portion 52a and the bottle bottom recessed portion 52c have a spring-like structure, the bottle can be elastically supported, which allows the bottle to be packed.
