    Abstract: The present invention involves a unitary composite article (10) and method of making same. The unitary composite article (10) comprises a one-piece, plastic body (14) and a stiffening material (26). The one-piece plastic body (14) includes a collapsible first portion having an inner cavity defined by an outer wall formed by an injection molding process. The plastic of the outer wall has a thickness which makes the outer wall susceptible to collapse into the inner cavity during normal usage of the article. The stiffening material (26) substantially fills the inner cavity by an injection process. The stiffening material (26) provides rigidity to the article (10) to prevent collapse of the outer wall into the inner cavity when the plastic body (14) experiences substantial external forces at the first portion during normal usage.

    Abstract translation: 本发明涉及一体式复合制品(10)及其制造方法。 整体复合制品(10)包括一体式塑料体(14)和加强材料(26)。 一体式塑料体(14)包括可折叠的第一部分,其具有由通过注射成型工艺形成的外壁限定的内部空腔。 外壁的塑料具有使制品正常使用期间外壁容易塌陷到内腔中的厚度。 加强材料(26)通过注射工艺基本上填充内腔。 当塑料体(14)在正常使用期间在第一部分经受实质的外力时,加强材料(26)为制品(10)提供刚性,以防止外壁塌陷到内腔中。
