Abstract
Description
米国特許第6,245,199号は、トレイをパルプ成形する方法を説明する。ここで、開始材料は、セルロース繊維を含む懸濁液である。雄型半体は、懸濁液の槽に浸漬され、型半体は次に、加熱および加圧下で共にプレスされる。
本明細書の実施形態は、従来技術の設計にまだ存在する、調和が困難な相互関連した課題の複合体を解決することを意図する。

b.コアスペーサ構造を与え、成形パルプシェルの内側に補強スペーサ構造を接着する段階と、
c.成形パルプまたは別のフレキシブルな紙ベースの材料で作られる内側シェルを与え、コアスペーサ構造にそれを接着する段階と
を含む。
a.湾曲した成形パルプシェルを形成すべく、エラストマー材料でスプレーコーティングされた、または鋳造された第1雄金属型半体と、第2雌金属型半体との間に水ベースのパルプスラリーをプレスし、加圧下の高温でパルプスラリーを乾燥する段階と、
b.コアスペーサ構造を与え、成形された湾曲パルプシェルの内側に補強スペーサ構造を接着する段階と、
c.成形パルプで作られる内側シェルまたは別のフレキシブルな紙ベースの材料を与え、それをコアスペーサ構造に接着する段階と
を含む。
i)外側シェル17は、(例えば、パルプ成形装置およびそれに使用するための型と題した、出願人の同時係属中の特許出願第1550864−1号において説明される、大型の成形パルプ物体を製造するための新規な方法を用いることにより)3次元形状の成形パルプで作られる。これは材料の表面であり、滑らかで均一な表面を有し、複合的な3次元形状の設計を可能にする。
ii)これに限定されないが、Reboard(商標)のコアであり得るフレキシブルなスペーサ構造、紙のハニカム構造、成形コア構造(例えば、国際特許出願第WO2010138066A1に説明されるように)、または段ボールにに使用される、縦溝を付けることにより作製される波形のコア構造から成るコア18。
iii)成形パルプ、または例えば、内張りボードまたは紙ボード等のフレキシブルな紙ベースの材料で作られる内側シェル19。
i)サンドイッチ材料において外側シェルとして使用される機能性添加剤の添加の有り、または無しで、上述の装置を用いて3次元形状の成形材料17、または物体を与える段階と、
ii)サンドイッチ材料においてコアとして使用されるスペーサ材料18を与え、3次元形状の成形材料または物体に上記コアスペーサ材料を接着する段階と、
iii)スペーサ材料に接着することとなる3次元形状の成形材料または物体、あるいはフレキシブルな紙ベースの材料で作られる内側シェル19を与える段階と
を含む。
i)外側シェル17は、(例えば、パルプ成形装置およびそれに使用するための型と題した、出願人の同時係属中のスウェーデン特許出願第1550864−1号において説明される、大型の成形パルプ物体を製造するための新規な方法を用いることにより)3次元形状の成形パルプで作られる。これは材料の表面であり、滑らかで均一な表面を有し、複合的な3次元形状の設計を可能にする。
ii)これに限定されないが、Re−board(登録商標)のコアであり得るフレキシブルなスペーサ構造、紙のハニカム構造、成形コア構造(例えば、国際特許出願第WO2010138066A1に説明されるように)、または段ボールにに使用される、縦溝を付けることにより作製される波形のコア構造から成るコア18。
iii)成形パルプ、または例えば、内張りボードまたは紙ボード等のフレキシブルな紙ベースの材料で作られる内側シェル19。
