AI Technical Summary

Technical Problem

The three-layer sole structure on the market has problems such as poor wearing comfort, poor overall sturdiness, easy delamination and water seepage, and poor aesthetics, which cannot meet the diverse needs of consumers.

Method used

It adopts a three-layer structure, including a transparent plastic layer, an elastic foam material layer, and a plastic layer. The transparent plastic layer is wrapped around the foam material layer to form a two-layer adhesive structure, and grooves and anti-slip stripes are set in the heel to enhance the sturdiness and comfort.

Benefits of technology

It improves the aesthetics, comfort, and overall durability of the sole, reduces the risk of delamination and water leakage, and enhances the support comfort and shock absorption of the heel.

Description

TECHNICAL FIELD

[0001] The utility model relates to a sole. BACKGROUND

[0002] The three-layer sole structure on the market has many defects, such as poor wearing comfort, poor overall firmness of the multilayer sole structure, easy delamination and water seepage, poor aesthetic effect, and the like, which cannot meet various demands of consumers. SUMMARY

[0003] The utility model aims at the above problems and provides a three-layer sole which is beautiful, comfortable to wear, and has good overall firmness.

[0004] The utility model discloses a three-layer sole, which is composed of an upper layer, a middle layer and a bottom layer.

[0005] The utility model discloses a groove is equipped with on the bonding surface of the heel part of the plastic glue layer and the foamed material layer.

[0006] The utility model discloses a non-slip stripe is equipped with on the ground surface of the heel part of the plastic glue layer.

[0007] The utility model discloses a three-layer sole, which is composed of an upper layer, a middle layer and a bottom layer.

[0008] The utility model discloses a three-layer sole, which is composed of an upper layer, a middle layer and a bottom layer. BRIEF DESCRIPTION OF DRAWINGS

[0014] Referring to Figures 1 to 4 The embodiment is a three-layer sole, which is composed of an upper layer, a middle layer and a bottom layer. The upper layer is a transparent plastic glue layer 1, the middle layer is a foamed material layer 2 with elasticity, and the bottom layer is a plastic glue layer 3. The transparent plastic glue layer is integrally formed by a surface layer 11 and a rim 12 to form a recessed part 13 completely filled with the foamed material layer. The depth of the recessed part is consistent with the thickness of the foamed material layer, and the recessed part forms an exposed two-layer adhesive structure around the sole after the upper layer, the middle layer and the bottom layer are bonded. The plastic glue layer is provided with a groove 31 on the bonding surface of the heel part and the foamed material layer. The plastic glue layer is provided with an anti-skid stripe 32 on the ground-contacting surface of the heel part.

[0015] According to the manufacturing method of the embodiment, the foamed material layer with elasticity is completely lined and bonded in the recessed part of the transparent plastic glue layer integrally formed by the surface layer and the rim. The transparent plastic glue layer and the foamed material layer are changed into a one-layer sole layer through the rim covering, and then bonded with the bottom layer of the plastic glue layer. In this way, the three-layer sole is changed into a sole with an exposed two-layer adhesive structure, and the overall firmness is better.
