Title:
HOLLOW BODY AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/029761
Kind Code:
A1
Abstract:
Provided are a hollow body and a manufacturing method therefor, which do not use celluloid and with which advantages such as a fitting joint not being generated are obtained. A thermoplastic elastomer, which is able to crosslink to a high degree by chemical crosslinking, is placed in a mold with a crosslinking agent added. As a result of preforming by pressurizing and heating at a temperature and a time in which the crosslinking reaction does not occur or, if the crosslinking reaction does occur, the crosslinking is not completed, a hollow first half (7) with an opening (7a) on one side and a hollow second half (9) with an opening (9a) on one side are each separately obtained. Next, with the edge of the opening (7a) of the first half (7) abutted against the edge of the opening (9a) of the second half (9) inside the molds (1, 1), the halves are heated at a high temperature and crosslinked to unite the first half (7) with the second half (9) and form a hollow body (10), and to cause said hollow body (10) to have adequate hardness.
