As shown in Fig. 2,2A, 2B and 3, knapsack can be included in laptop computer cover or the laptop computer cover independently in the back pocket of wall 20, as after will be disclosed in conjunction with Figure 20 to 23.In Fig. 2,2A, 2B and 3, this cover comprises and being connected in the back pocket and at a pair of buffering covering of first face wall, 20 back, each buffering covering comprises a plurality of isolated, parallel, permanent seal and the partially filled tracheae of being made by flexible elastoplast 40, between each tracheae 40 brace 48 is arranged in each buffering covering.In buffering covering each tracheae 40 each all towards the brace 48 of another buffering covering, thereby as Fig. 2 A as shown in, minimize when the space between these buffering coverings during without any thing the shared volume of these buffering coverings and as Fig. 2 B as shown in, cushioning be placed on these and cushion laptop computer 50 between coverings.

As mentioned above, these buffering coverings are by extending in when bump thereby absorbing energy and the elastoplast this energy not transferred on the laptop computer is made as PU or PVC.

As shown in Figure 3, this cover can also have the tracheae 46 at the permanent closure made by flexible elastomeric material and partially filled top, at these buffering one of coverings---be connected with top brace 48 between in this case for the top of this front covering and top tracheae 46 and be used for covering and cushion these and cushion space between coverings, and the tracheae 42 of the pair of sidewalls of being made by permanent seal and the partially filled flexible elastomeric material by identical and the tracheae 44 of bottom, thereby each sidewall and the place, bottom that are connected to the space between these buffering coverings further cushion the space shown in Fig. 2 and 3.

Referring now to Figure 20 to 23, the independently laptop computer cover of this utility model includes the fiber enclosing cover 52 of front covering and back side covering, and this front covering has the pocket 54 of top dress slide fastener, and this back side covering has the pocket 56 of top dress slide fastener.This front and back cover piece covering is connected to each other by bottom and the sidewall that angle brace sheet 60 extends across these pocket covers.Have vertical main slide fastener 58 top angle brace sheet 62 close cap periphery and the opening that is used for inserting and taking out laptop computer is provided.

Each all comprises a plurality of isolated, parallel, permanent seal and the partially filled tracheae of being made by flexible elastomeric material 40 at this a pair of buffering covering, between each tracheae 40 brace 48 is arranged in each buffering covering.These front and back buffering coverings insert front and back

cover piece piece

54 and 55 respectively by these top zipper on the direction of arrow in Figure 20.Each tracheae 40 of a buffering covering each all towards each brace 48 of another buffering covering, thereby minimize when the shared volume of these buffering coverings during of the space between these buffering coverings without any thing.In this space laptop computer is arranged, the laptop computer between these buffering coverings is cushioned.

Figure 21 illustrates this cover piece and be in decomposing state before the cover piece piece 54 that slide fastener is housed and 56 peripheries has been sewn to or has been connected on

angle brace sheet

60 and 62.

As shown in Figure 22, this cover also preferably includes the permanent seal made by flexible elastomeric material and partially filled top tracheae 46 and is used for covering and cushion space and wherein arbitrary laptop computer between these buffering coverings, cushions between one of coverings or the cover piece piece of this side and the top tracheae 46 at these and is connected with top brace 48.As shown in Figure 23, thus the tracheae 44 of the tracheae 42 of permanent seal of being made by flexible elastomeric material and partially filled pair of sidewalls and bottom is connected to each side and the place, bottom in the space between these buffering coverings further cushions this space.This provides

side fibre pipe

60a and 60c and bottom fiber pipe 60b to finish by giving angle brace sheet 60, they each the pipe 42 that is used for receiving on the direction of arrow in Figure 23 separately and 44 opening all arranged.After each pipe 42, as inserting successively 44 and 42 of illustrating among Figure 23, the angle brace sheet is sewn on the front and back cover piece covering to finish this

cover.Pipe
