Embodiment 1

[0060] see Figures 1 to 3 As shown, the insole of this embodiment has a hard shell 10 and a soft cushion body 20 connected with the hard shell 10 .

[0061] The aforementioned hard case 10 has a pad body 11 , a fixing portion 12 connected to the pad body 11 , and a support portion 13 connected to the pad body 11 and the fixing portion 12 . The pad body 11 has a rear part 111, a middle part 112, and a front part 113 connected in sequence, and the rear part 111, the middle part 112 and the front part 113 respectively have a medial surface and a The outer side of the side. The fixing portion 12 protrudes from the periphery of the rear portion 111 of the pad body 11 , and the fixing portion 12 has an inner surface and an outer surface opposite to the inner surface. The support portion 13 protrudes from the periphery of the midfoot portion 112 and the forefoot portion 113 of the pad body 11 and is connected to the fixing portion 12. The support portion 13 has an inner surface an...

Embodiment 2

[0064] see Figure 4 As shown, the insole of this embodiment is roughly as described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that in this embodiment, the mid-foot portion 112 of the pad body 11 is arched toward the direction of the cushion body 20, so as to correspond to the arched arch in the center of the sole of the human body, so it fits The position of the cushion body 20 corresponding to the midfoot portion 112 on the inner surfaces of the rear foot portion 111 , the midfoot portion 112 , the forefoot portion 113 , the fixing portion 12 and the support portion 13 is also toward the cushion body 20 . The direction of the top surface 21 is arched.

Embodiment 3

[0066] see Figure 5 As shown, the insole of this embodiment is roughly as described in Embodiment 2, and will not be repeated here. The difference between this embodiment and Embodiment 2 lies in that the insole in this embodiment further has a fabric layer 30 which is attached to the top surface 21 of the cushion body 20 to serve as a layer in contact with the sole of the foot. Specifically, the fabric layer 30 is bristle cloth, but not limited thereto.

Abstract

The invention relates to an insole. The insole comprises a hard case. The hard case comprises an insole body, a fixing portion and a soft insole body. The insole body is provided with a foot rear portion, a foot middle portion and a foot front portion, wherein the foot rear portion, the foot middle portion and the foot front portion are sequentially connected and are respectively provided with inner side surfaces and outer side surfaces opposite to the inner side surfaces. The fixing portion protrudes and extends to the periphery of the foot rear portion of the insole body and is provided with an inner side surface and an outer side surface opposite to the inner side surface. The soft insole body is provided with a top surface and a bottom surface opposite to the top surface, wherein the bottom surface is attached to all portions of the insole body and the inner side surface of the fixing portion. The hardness of the hard case is larger than that of the soft insole body. The hard case and the soft insole body are integrally formed by heating spray-bonded non-woven fabric. The invention provides a method for preparing the insole. The method comprises the steps of providing the spray-bonded non-woven fabric; providing a mold, wherein the mold corresponds to the insole in shape and is provided with a heating surface; placing the spray-bonded non-woven fabric into the mold and attaching the spray-bonded non-woven fabric to the heating surface; and enabling the heating surface of the mold to be warmed until the temperature is between 160 to 200 DEG C.

Description

technical field [0001] The invention provides an insole, especially an insole with good ventilation effect and good shaping effect. The invention further provides a preparation method of the insole. Background technique [0002] Most of the existing insoles are made of ethylene vinyl acetate copolymer (EVA). EVA is cheap, so when used to make insoles, the cost can be greatly reduced. However, because the insole made of EVA material has many disadvantages, such as being airtight and impervious to water, when the insole is used in the shoe, it is easy to stuff the feet, which not only causes discomfort to the user, but also makes the feet more likely to produce peculiar smell, and when there is sweat on the feet At the same time, sweat tends to stay on the surface of the insole, and the soles of the feet are in a damp state, so bacteria breed, which in turn greatly increases the chances of getting foot and other diseases. In addition, EVA insoles are soft and have a poor rec...
