| 发明名称 | Method for manufacturing hollow structure for breathing mask | ||
| 摘要 | A method for producing a filled hollow structure includes producing an open hollow structure of a first material, positioning the open hollow structure on a tool adapted to hold the open hollow structure, filling the open hollow structure with a filler medium, and closing the filled open hollow structure with a second material. A hollow structure may be produced by such method, and a tool may be structured to perform such method. | ||

| 主权项 | 1. A method for producing a filled hollow structure of a breathing mask, comprising: producing an injection-molded open hollow structure of a first material; positioning the open hollow structure on a tool adapted to hold the open hollow structure; filling the open hollow structure with a filler medium while the hollow structure is positioned on the tool; closing the filled open hollow structure with a second material while the hollow structure is positioned on the tool; and curing the second material when the second material is in a different state than the first material, wherein the second material is an elastomer, and wherein an end portion of the hollow structure forms a contact zone configured to rest against a patient's face. | ||
