Abstract
A liner structure includes a liner main body and an insert located inside an opening of the liner main body. The liner main body is made of a polybutylene material. The liner structure has relatively good heat resistance within a temperature range corresponding to conventional liquid water, and can be used for containing hot water. Moreover, a feasible manufacturing method is provided. The method can overcome defects of material characteristics through process optimization, so that can implement manufacturing the liner structure.
Claims8
A liner structure, comprising a liner main body and an insert located inside an opening of the liner main body, wherein the liner main body has a portion which is at the opening and covers a top surface of the insert, so that the insert is not exposed on an outside of the liner main body, wherein the top surface of the insert faces an opening direction of the opening of the liner main body, wherein the liner main body is made of a polybutylene material;
- wherein the insert and the opening of the liner main body are nested with each other;
- wherein the insert is provided with a via, and an extension protruding from the portion of the liner main body is disposed at the opening of the liner main body and extends through the via;
- wherein a diameter of a front end of the extension is larger than a diameter of the via, wherein the front end of the extension faces away from the portion of the liner main body and extends beyond the via.
A blow-molding manufacturing method for a liner structure, wherein the liner structure comprises a liner main body and an insert located inside an opening of the liner main body, wherein the liner main body has a portion which is at the opening and covers a top surface of the insert so that the insert is not exposed on an outside of the liner main body, wherein the top surface of the insert faces an opening direction of the opening of the liner main body;
- wherein the insert and the opening of the liner main body are nested with each other;
- wherein the insert is provided with a via, and an extension protruding from the portion of the liner main body is disposed at the opening of the liner main body and extends through the via;
- wherein a diameter of a front end of the extension is larger than a diameter of the via, wherein the front end of the extension faces away from the portion of the liner main body and extends beyond the via;
- the blow-molding manufacturing method for the liner structure comprising:
- preheating the insert;
- and
- conveying a polybutylene material blank from a neck ring mold, wherein a temperature range of the material blank is 170° C. to 230° C. when the material blank is conveyed from the neck ring mold.
