The specific embodiment

Before the EVA material liners to the utility model describes, be necessary to understand earlier the structure of EVA material liners of the prior art.

Accompanying drawing 1 shows the perspective view of the EVA material liners that is used for knapsack in the prior art.Sheet material as the EVA liner section bar of knapsack material normally utilizes thermoforming process to process can cut into suitable size and dimension with it according to actual needs and be used to make knapsack, for example as the back pad and the shoulder belt gasket material of knapsack.In order to strengthen the gas permeability of EVA material liners, also comprise a plurality of punchings on the gasket material of the prior art, so that air therefrom flows through.Accompanying drawing 2 shows the front view of the EVA material liners that is used for knapsack in the prior art, and has clearly illustrated the distribution of a plurality of punchings on it.

In the prior art, the EVA material liners that is used for knapsack is all processed one side usually and is the plane, and another side is repeated concaveconvex shape.Fig. 3 shows the side view of the EVA material liners that is used for knapsack in the prior art, therefrom can be clear that this structure of prior art EVA material liners.From the Fig. 1 that shows this EVA material liners perspective view, also can see this structure.

Preceding text are mentioned; Because the one side of EVA material liners is the plane in the prior art; So the contact area of the back side of knapsack and/or shoulder belt place and human body is bigger when the people bears knapsack; Cause in these contacts site to be difficult for ventilation and heat, so the user can gather heat when bearing knapsack for a long time between knapsack and human body back, shoulder, make the user not feel well.Even if on the EVA material liners, punching is set, can not obtain good circulation of air effect yet.

The utility model has proposed improved technical scheme to the EVA material liners of prior art.Utilize the EVA gasket material of the utility model, can significantly improve user's ventilation effect between knapsack and human body back and the shoulder when bearing knapsack, thereby reduce to minimum to the heat that back and shoulder place gather.
