Water bag
Abstract
Abstract Translated from Japanese (57)【要約】 【課題】 ウォーターバッグ本体の外周部分に集中す る圧力荷重により、比較的強度の弱い溶着部分が破損す るのを防止する。 【解決手段】 ターポリンシート1の縁部同士を溶着 して、ウォーターバッグ本体aを構成し、ターポリンシ ート1の溶着部分eを、ウォーターバッグ本体aにおけ る外周部を除く上面又は下面のどちらか片面の範囲内に 収めて構成し、内部圧力が溶着部eに集中して加わるの を回避する。 (57) [Problem] To prevent a welded part having relatively low strength from being damaged by a pressure load concentrated on an outer peripheral part of a water bag body. SOLUTION: An edge portion of a tarpaulin sheet 1 is welded to each other to form a water bag main body a, and a welded portion e of the tarpaulin sheet 1 is formed on one side of an upper surface or a lower surface excluding an outer peripheral portion of the water bag main body a. The pressure is set within the range to avoid the internal pressure from being concentrated on the welded portion e.
