摘要： Embodiments include container assemblies for presentation of contents. In one example, a container assembly for writing instruments may include a slideable platform with a threaded hole configured to operably receive a threaded post therethrough, a housing having at least one guide rail, a manually rotatable base configured to rotate, such that rotation of the manually rotatable base moves the slideable platform within the housing along the at least one guide rail, and at least one platform stopper configured to prevent the slideable platform from advancing past the pre-determined height, wherein the pre-determined height is selected such that the writing instruments are retained by the housing in the container assembly when the slideable platform is in contact with the at least one platform stopper.

摘要： A double-chuck mechanical pencil comprises: a barrel; a barrel cap attached to the barrel; a lead tank axially slidably inserted in the barrel; a back chuck fixedly joined to the front end of the lead tank; a chuck ring loosely fitted on the chucking head of the back chuck; a tubular member disposed so as to surround the front portion of the lead tank; a back elastic member placed in the tubular member so as to bias the lead tank backward; a coupling member combined with the tubular member, and provided in its inner circumference with stopping portions with which the tubular member and the chuck ring come into contact, respectively; a front chuck fixedly joined to the front portion of the coupling member; and a front elastic member interposed between the barrel cap and the coupling member so as to bias the coupling member backward. A rotation prohibitor permits the axial movement of the coupling member and prohibits the rotation of the same relative to the tubular member. A tail cap is attached to the back end of the barrel and a push cap is detachably put on the back end of the lead tank. Another rotation prohibitor permits the axial movement of the push cap and prohibits the rotation of the same relative to the tail cap.
摘要翻译：双卡盘自动铅笔包括：桶; 桶盖附在桶上; 轴向可滑动地插入桶中的铅槽; 固定地连接到铅罐的前端的后卡盘; 卡盘环松动地安装在后夹盘的夹头上; 管状构件，其设置成围绕铅罐的前部; 背部弹性构件，其放置在所述管状构件中，以将所述铅槽向后偏置; 联接构件与管状构件结合，并且在其内周设置有分别与管状构件和卡盘环接触的止动部分; 固定地连接到所述联接构件的前部的前卡盘; 以及插入在所述筒盖和所述联接构件之间以将所述联接构件向后偏置的前弹性构件。旋转禁止件允许联接构件的轴向运动并且禁止其相对于管状构件的旋转。尾盖连接到桶的后端，并且将推盖可拆卸地放置在铅罐的后端。另一个旋转禁止件允许推盖的轴向移动并且禁止其相对于尾盖的旋转。
