摘要： An expandable media filter structure is composed largely of biodegradable materials and is environmentally disposable. A plurality of pleated panels are interconnected at their edges so as to be collapsible for storage and shipping purposes but expandable for installation and use. A plurality of ribbons are ultrasonically welded to each of the panel edges, wit the ribbon portions between edges being of substantially equal lengths, thereby maintaining equal spacing between the panel edges when the filter is in the expanded condition but allowing an easy collapsing of the filter for storage. Forming a part of the disposable filter are pair of end plates, with each being adhesively attached to an end panel and having a pair of slots formed near their ends for attachment to a nondisposable support structure. The end panels are formed of multiple layers of paperboard which are adhesively bonded and compressed into a U-shaped structure that rigidly supports the filter in its expanded condition. The nondisposable support structure includes a pair of molded plastic side caps that fit over the respective ends of the filter panels and the end plates. Each side cap has a pair of flanges at its opposite ends which act to maintain the filter in its expanded condition when the end plates are placed in abutting position therewith. Each side cap also includes a boss which fits into a respective end plate slot to hold the end plates in their installed positions within the side caps.
摘要翻译：可膨胀介质过滤器结构主要由可生物降解的材料组成，并且是环保的。多个褶皱面板在它们的边缘处相互连接，以便可折叠以用于存储和运输目的，但可扩展以用于安装和使用。多个带被超声波焊接到每个面板边缘，边缘之间的带部分具有大致相等的长度，从而当过滤器处于膨胀状态时允许面板边缘之间的相等的间隔，但允许过滤器容易地折叠用于存储。形成一次性过滤器的一部分是一对端板，每个端板粘合地附接到端板并且具有在其端部附近形成的一对槽，用于附接到不可涂覆的支撑结构。端板由多层纸板形成，粘合地粘合并压缩成U形结构，其在其膨胀状态下刚性地支撑过滤器。非一次性支撑结构包括一对模制塑料侧盖，其配合在过滤板和端板的相应端部上方。每个侧盖在其相对端具有一对凸缘，当端板与其邻接的位置放置时，它们用于将过滤器保持在其膨胀状态。每个侧盖还包括凸台，该凸台装配到相应的端板槽中，以将端板保持在侧盖内的安装位置。
