摘要： There is provided a new and useful protective cover for an optical disc of circular configuration having a circular aperture centered therein and having an outer edge. The protective cover is a sheet of film of generally circular configuration corresponding to the configuration of the disc, wherein the film is of a material that will not interfere with the read process of the disc when the cover is in place about the disc. The protective cover has a plurality of clasps spaced about a circumferential edge of the film to engage the disc about its outer edge in a snap fit. The invention also relates to a method of applying such a protective cover to such an optical disc comprising the steps of holding the cover with the clasps in a closed position oriented relative to the film toward said disc, expanding the clasps to an open position wider than an outside diameter of the disc, placing the disc within the expanded clasps, concentric with the cover and returning the clasps to the closed position whereby they engage the disc about the outer edge in a snap fit.
摘要翻译：提供了一种用于圆形构造的光盘的新的和有用的保护盖，其具有以其中心的圆形孔并具有外边缘。保护罩是与盘的结构相对应的大致圆形构造的薄片，其中，当盖在盘周围的适当位置时，该膜是不会干扰盘的读取过程的材料。保护罩具有围绕胶片的圆周边缘间隔开的多个扣环，以卡扣配合使其围绕其外边缘接合。本发明还涉及一种将这样的保护盖应用于这种光盘的方法，包括以下步骤：将盖子保持在相对于胶片朝向所述盘定位的关闭位置中，将该卡扣扩大到比盘的外径，将盘放置在膨胀的钩中，与盖同心并将扣返回到关闭位置，由此它们以卡扣配合的方式接合盘周围的外边缘。

摘要： There is provided a new and useful apparatus for applying a removable protective cover to an optical disc in which the optical disc has a circular configuration, an aperture centered therein and an outer edge. The cover comprises at least one sheet of film of generally circular configuration which corresponds to the circular configuration of the disc. The cover is constructed of a material that will not adversely interfere with the read process of the disc when the cover is in place about the disc. The cover further comprises a plurality of resilient clasps spaced about a circumferential edge of the film to engage the disc about its outer edge in a snap-on spring-like fit. The apparatus has a base to hold the cover with the clasps in a closed position oriented upwardly away from the base, a moveable expanding means to urge the clasps from the closed position to an open, disc-receiving position, centering means to orient and hold the disc concentric with the cover and a top having an inside face and an outside face. The top comprises press means to exert a force on the disc in the direction of the cover, whereby the force urges the edge of the disc to co-operate with the expanding means to expand the clasps into the open disc-receiving position while urging the disc in position within the cover whereby the clasps return to the closed position thereby engaging the edge of the disc in the snap-on spring-like fit.
摘要翻译：提供了一种用于将可移除的保护盖应用于其中光盘具有圆形构造的光盘的新的有用的装置，其中的孔径和外边缘。该盖包括至少一片大致圆形构造的薄片，其对应于圆盘的圆形构型。盖子是由一个材料构成的，该材料不会对盖子在盘上就位时对盘的读取过程产生不利影响。盖子还包括围绕胶片周向间隔开的多个弹性扣环，以卡扣弹簧状配合的方式使其围绕其外边缘接合。该装置具有底座，用于将盖子保持在相对于底座向上取向的关闭位置的夹子;可移动的膨胀装置，用于将夹子从关闭位置推动到打开的盘接收位置;定心装置定向和保持所述盘与所述盖同心并且具有内表面和外表面的顶部。顶部包括沿着盖的方向在盘上施加力的压力装置，由此该力促使盘的边缘与膨胀装置协作，以将扣子膨胀到打开的盘接收位置，同时推动盘在盖内的适当位置，由此卡扣回到关闭位置，从而以卡扣弹簧状配合接合盘的边缘。
