At this moment, muscle shape folding line Z is identical with the situation that main folding line A, B and other folding lines are set, and available known press-working method forms.

When this effective reinforcement shape folding line Z is subjected to the excessive impulsive force of the side of testing oneself at hollow two double walls 1,2, make above-mentioned end face 7a, flexibly deflection of 8a, up to the effect that absorbs impulsive force.

With two double walls form Outboard Sections on the sheet 9 and 10, parallel folding line Y, the length of sidewall sections vis-a-vis that promptly constitutes the another side of the recess S that cooperates usefulness dwindles, make it to cooperate the width dimensions of the recessed S of usefulness to be complementary with this.On two ends separately of this crevice 18,19, be provided with for being inserted into and be located at insert-connecting plate 18a, the 19a that two double walls form 1 li of cut channel on the sheet 7 and 8.

Below, the effect of said structure is described with reference to Fig. 6 of the running condition of representing liner 201.

When a corrugated board 101 as shown in Figure 1, that flatly launched keeping is folded into liner 201, arrest the left and right sides part of corrugated board 101 earlier, resemble as shown in Figure 2,, make the upright easily pleat that forms of each supporting blade 5 with rising two main folding line A, A bending downwards quickly.Folding line C, the D and each the banded folding line K that strengthens sheet 12 that make two double walls form the intersection of sheet 7,8 and bottom sheet 11A, 11B again upwards form to bending pleat respectively.

Then, as shown in Figure 3, two double walls of corrugated board about 101 (as shown in Figure 1) are formed sheet 7,8 be bent into " " word shape mutually inwardly, simultaneously folding line C, D upwards are converted into the right angle, corrugated board 101 is converted into the groove shape that is spill.

In the operating process of this bending, since approaching in opposite directions two outside wall surface 7a, 8a and make them upright in, make each supporting blade 5 two ends pressurized between two outer wall 7a, 8a, thereby the just easy upwards bending of each bar cut channel G, H of being provided with the half tangent line in the inboard, each supporting blade 5 is naturally and understandably stood upright on the sheet 6 of the inside.

Under this state, the supporting blade 5 of (in Fig. 1) about the inside sheet 6 constitutes the madial wall below part of hollow two double walls 3,4 as shown in Figure 3; And four supporting blades 5 in the middle of these supporting blades 5, the supporting blade 5 of per two adjacency is upright overlappingly, forms two overlapping states, and formation is the state of support base dough sheet 11A, 11B securely from two positions of downside.

Then, make each enhancing sheet 17 on the two side ends that is connected outside wall surface 7a, 8a inwardly be converted into the right angle, as the open end face in both sides that stops up the bending grooving shape part of living in to state.At this moment make little bent sheet 17a to the horizontal direction bending, the end face of support hollow two double walls 3,4.

At last, as shown in Figure 4, two double walls are formed sheet 9,10 inwardly be bent into " " font, simultaneously insert-connecting plate 18a, the 19a of narrow 18,19 both sides being inserted in two double walls respectively forms in each cut channel I set on 7,8, just can be different with the explanation of above-mentioned very long folding operation, can be folded into liner 201 extremely easyly, rapid and infallible.

Fig. 6 represents to be made into two liners 201 being converted into like this, with accurate electric device etc. the situation of bale packing article 300 usefulness corrugated fibre boxs 400 bale packings of cuboid.

In two end interlockings of the recess S of the cooperation usefulness of each liner 201 and bale packing article 300, under this state, bale packing article 300 are contained in the corrugated fibre box 400, just can finish the bale packing operation extremely easy, rapidly, reliably.

Under this bale packing state, about the both side ends of bale packing article 300, the front and back peripheric surface all is in the state that is enclosed among the hollow two double wall 1-4, and two overlapping bottom sheet 11A that support by supporting blade 5,11B then abuts against on the end face of both sides.

Like this, and combine, bale packing article 300 can be remained in the corrugated fibre box 400 with superior and not poor buffer status when using foamed styrene system liner in the past as the peculiar good buffer action of the corrugated board of liner 201 structure blanks.

Make hollow two double walls 1,2 of longitudinally of the liner 201 of elongated cuboid, compare with hollow two double walls 3,4 of Width, do not have enough strong structure, and because span is longer, thereby the function of function of support section lotus and even buffering all can be relatively poor.

But, because on end face 7b, the 8b of hollow two double walls 1,2, be provided with muscle shape folding line Z as illustrated in fig. 7, thereby be subjected at these hollow two double walls 1,2 under the situation of the other excessive impulsive force that comes from side, these two roof face 7b, 8b flexibly deflections as shown in Figure 8, thus can make excessive impulsive force decay effectively.

Because gap set between the top of end face 7a, 8a and supporting blade 5 when its width appropriate change, can make the anti-load performance of hollow two double walls 1,2 change, thereby can control the pooling feature of muscle shape folding line Z.

The integrated buffer performance of liner is further improved.

Fig. 9 and Figure 10 represent an alternative embodiment of the invention.

The main difference of the liner 202 of this embodiment and the liner 201 of the foregoing description is that this embodiment is the resettlement section of hollow two double walls 4 in hollow two double walls 1～4 being made the attached part in addition etc. of collection bale packing article.

In order to confirm in this resettlement section, whether to have collected little article from the outside, easily, circular window 20 is set in two double wall formation place 10.

Different corresponding with the shape of formed jut on the bale packing article and position, the shape that forms cut channel set on the sheet 8 at two double walls is also different with the position.And on two double walls form sheet 9, be provided with cut channel for same purpose.

Can the little bent sheet 13 that two double walls form on the sheet 7,8 be saved, make it when liner 202 folding operations, can not cause trouble.But, 13 pairs of structural strengths that improve liner 202 of this little bent sheet still are effective.

In above-mentioned various structures, muscle shape folding line Z is not limited to linearity, can be arranged to zig-zag or corrugated, also can separate proper spacing, is provided with many.And its formation position also is not limited to end face 7a, 8a, for example is such walls parallel with the impulsive force direction such as supporting blade 5 grades, by on the direction that intersects with the impulsive force direction muscle shape folding line Z being set, just can bring into play its buffer action effectively.

In addition, the each several part size of liner 201,202 can arbitrarily be set corresponding to the shape of bale packing article certainly.

Can be clear by above-mentioned explanation, the collapsible liner that corrugated board of the present invention is made with The liner of front foamed styrene system is compared, and good effect in the following described practicality is arranged.

(a) because on a corrugated board, as long as by folding line, perforation processing being set just Can make, thereby can provide cheaply.

(b) owing to can be taken care of and be transported with the state of the compactness that flattens, thereby can be significantly Keeping and freight are saved in degree ground.

(c) can play a role aspect the saving petroleum resources.
