    • A manually operable ejector holder is provided for effecting discharge of a capsule-like cartridge (34). A capsule-like cartridge (34) comprising a cylindrical body of uniform diameter open at one end and provided with an annular flange (56) surrounding the open end, the other end being closed by an integral hemispherical end (62) of the same radius as the body and provided with an angularly extending discharge nipple (64) communicating with the interior of the hemispherical end of the body which may be loaded with a precisely measured quantity of a material and the open end closed by a plug slideably moveable along the body when one end is engaged by a plunger (18), are provided in combination with an ejector holder having a cylindrical body provided with an ejecting plunger (18) operated by a handle (22) in a cooperative pivoted lever member (24). The forward end (16) of the cylindrical body of the handle is partially cut away in a radial direction for a limited distance longitudinally to provide a hollow seat to receive the flanged end (56) of the cartridge (34), the seat having an undercut groove (58) to receive the flange (56) of said cartridge (34), and the side walls (36, 38) of the seat at the upper edges having limited flexibility and spaced apart a slightly less distance in the diameter of the cartridge body to effect a limited snap-acting connection of the cartridge (34) to the holder. The body and plug of the cartridge (34) are preferably molded from an opaque material impervious to the passage of light and the tip of the nipple (64) is closed by a cap (70) which may be colour coded to indicate various facts such as the type of material, weight or quantity thereof. Several embodiments of lever members and support mechanisms for the ejector holder are provided.
    • 提供了一种手动操作的喷射器固定器,用于实现胶囊状盒(34)的排出。 一种胶囊型盒(34),包括具有均匀直径的圆柱形主体,其一端开口并设置有围绕开口端的环形凸缘(56),另一端由相同半径的整体半球形端(62)封闭 作为主体并且设置有角度延伸的排出接头(64),其与主体的半球形端部的内部连通,该内部可以装载精确测量的材料量,并且开口端通过沿着主体可滑动地移动的插头封闭 当一端与柱塞(18)接合时,与具有圆筒体的喷射器保持器组合设置,所述喷射器保持器设置有在协作转动杆构件(24)中由手柄(22)操作的弹出柱塞(18)。 手柄的圆柱形主体的前端(16)在径向方向上被部分地沿着纵向方向被切除有限的距离,以提供中空的座位以容纳盒(34)的带凸缘的端部(56),座椅具有 底槽(58)以容纳所述盒(34)的凸缘(56),并且在上边缘处的座的侧壁(36,38)具有有限的柔性并且间隔开一点距离 盒体以实现盒(34)到保持器的有限的快动连接。 盒(34)的主体和插头优选地由不透光的不透明材料模制,并且乳头(64)的尖端被盖(70)封闭,盖(70)可以被颜色编码以指示各种事实,例如 作为材料的类型,重量或数量。 提供了用于喷射器保持器的杆构件和支撑机构的几个实施例。
