The specific embodiment

Below, describe the utility model in detail with reference to accompanying drawing.

Fig. 3 is to use the exploded perspective view when being divided into four vacuum forming damper element packed goods of the present utility model.Fig. 4 is contained in cross sectional drawing in the packing chest of Fig. 3 to goods of packaging etc.

Among Fig. 3, label 10 is goods, and label 21 is accessory cases, and label 20 is packing chests, and label 11 ' is the vacuum forming damper element.

As shown in Figure 4, vacuum forming damper element 11 ', goods 10 and accessory case 21 all are housed in the packing chest 20 of the cube chest made from corrugated board and so on, and, vacuum forming damper element 11 ' is supporting goods 10 with its step surface 15 from the below, and packaged goods 10 in clamping on the direction of all around.

The top of the not use vacuum forming damper element 11 ' clamping of goods 10 is covered on it with the accessory case 21 that annex, specification sheets and so on are housed, and cushions.If do not use accessory case 21, also can use other damper element, for example, corrugated board, foamed plastic damper element, vacuum forming damper element wait and cushion, and adopt the technical scheme of these damper elements all to be included in the scope of the present utility model.

As shown in Figure 4, four sides 22 that are the accessory case 21 of box type construction contact with roof with the sidewall of packing chest 20 with end face, and its bottom surface then is bearing on the upper surface 14 ' of vacuum forming damper element 11 '.Because four sides 22 of accessory case 21 all are on the outward flange position in addition of goods, and, the height from step surface 15 to end face 14 ' of damper element 11 ', be slightly larger than the height of the goods of packaging, so the load that applies from the packing chest top just all is pressed on the upper surface 14 ' of vacuum forming damper element 11 '.Because there is very sufficient space accessory case 21 inside on short transverse, very big distortion leeway is arranged, so accessory case 21 cores are very little to the goods applied pressure.In addition, the lateral wall 16 of damper element 11 ' and madial wall 17 are all made as shown in the figure skewed.

Fig. 5 is illustrated under the state that is packaged into Fig. 4, when a packing chest falls down, and when the vacuum forming damper element in the packing chest is subjected to impulsive force that goods applies, the variation that the damper element shape is taken place.

As shown in Figure 5, when pawning fallen packing chest and landing, the impulsive force by acceleration due to gravity produced that is placed on the goods 10 on the step surface just all acts on the above-mentioned step surface 15 of damper element.At this moment, owing to be provided with the reinforced rib of the concaveconvex shape that extends along the vertical direction on damper element 11 ' and the sidewall 16 packing chest contacts side surfaces, its rigidity is bigger, thereby the degree of dip of sidewall 16 changes less.And damper element 11 ' not with the sidewall 17 of packing chest contacts side surfaces on, because do not have to be provided with the reinforced rib of the concaveconvex shape that extends along the vertical direction, its rigidity is very poor, thereby causes the degree of dip of sidewall 17 to alter a great deal, step surface 15 is sunk, and the related degree of dip that strengthens sidewall 16.So, space (exaggerated among Fig. 5 this gap) just between the bottom surface of the end face of goods 10 and accessory case 21, occurred, thereby absorbed kinetic energy when falling with the distortion of damper element 11 ', reduced impulsive force to goods 10.

See also Fig. 6, because the reinforced rib of the concaveconvex shape that extends along above-below direction is arranged on damper element and the sidewall packing chest contacts side surfaces, its rigidity is higher, thereby the load that applied of the accessory case 21 that born of vacuum forming damper element 11 ', the above-mentioned sidewall that just all passes through damper element 11 ' is delivered on the bottom surface of damper element 11 '.When several packing chests 20 were stacked together, the above-mentioned sidewall that above-mentioned load also is piled up by each damper element transmitted downwards, reach nethermost packing chest after, pass to ground or floor at last.Therefore, adopt the vacuum forming damper element of the utility model structure, produce and load transmitted between packing chest, the overwhelming majority is all transmitted by damper element, and is not applied on the goods, thereby helps protecting the goods that is loaded in wherein.

See also Fig. 7, Fig. 8 and Fig. 9.Fig. 7 is the birds-eye view of vacuum forming damper element of the present utility model when making four block buffering spares, 11 ' a, and the damper element of this form is applicable to the goods that planar dimension is very big.Fig. 8 is the birds-eye view when vacuum forming damper element of the present utility model is made two block buffering spares, 11 ' b, and the damper element of this form is applicable to the goods of medium planar dimension.Fig. 9 is the birds-eye view of vacuum forming damper element of the present utility model when making a monoblock damper element 11 ' c, and the damper element of this form is applicable to the goods that planar dimension is less.
