    • A tamper-evident container assembly comprises a container and a cap. The container has a dispensing end that includes an opening through which the contents of the container can be dispensed, a threaded surface, and a frangible tab extending outwardly from the threaded surface. The cap is internally threaded with the threads of the cap being complementary to those of the threaded surface of the dispensing end of the container and being formed prior to the cap being placed on the dispensing end of the container. The cap has a vertical notch therein extending from the lower edge thereof of a size sufficient to receive at least a portion of the tab so that the tab is readily visible therethrough. The cap is initially placed axially over the dispensing end of the container so that the tab is received within the notch in the cap.The cap can not be initially removed from the container without separating at least a portion of the tab from the threaded surface of the dispensing end of the container. The tab is separated from the threaded surface of the container by twisting the cap with respect to the container, so that the absence of the tab from the threaded surface of the dispensing end of the container indicates that the container has previously been opened.
    • 防窃启容器组件包括容器和盖。 该容器具有分配端,该分配端包括可以分配容器内容物的开口,螺纹表面和从螺纹表面向外延伸的易碎片。 盖子内螺纹,帽子的螺纹与容器的分配端的螺纹表面的螺纹互补,并且在盖子被放置在容器的分配端之前形成。 盖子具有从其下边缘延伸的垂直切口,其尺寸足以容纳至少一部分突片,使得突片容易通过其中可见。 盖最初轴向地放置在容器的分配端上,使得突出部被容纳在盖的凹口内。 顶盖不能从容器中首先取出,而不会将突片的至少一部分与容器的分配端的螺纹表面分离。 通过相对于容器扭转盖,突片与容器的螺纹表面分离,使得从容器的分配端的螺纹表面没有突片指示容器先前已经打开。

    • A headed thermoplastic tube is formed solely from a thermoplastic extruded, stretched, sleeve by positioning the sleeve over a forming mandrel so the sleeve has an exposed portion. While rotating the forming mandrel which holds the sleeve, the inner surface of the exposed portion of the sleeve is heated above the glass transition temperature of the thermoplastic material to render the inner surface molten while the outer surface provides support for the exposed portion of the sleeve. The heated exposed portion is then shaped into a conical shape, such as by heating the outer surface, the rotation of the mandrel is stopped and pressure applied to the conical shaped exposed portion to form a headed thermoplastic tube. The headed tubes produced have a body portion, shoulder portion and neck portion, without any seams, all of which are formed from the starting thermoplastic extruded, stretched sleeve.
    • 通过将套筒定位在成形心轴上,使得套筒具有暴露部分,仅由热塑性挤出的拉伸套筒形成头部热塑管。 在旋转保持套筒的成形心轴的同时,套筒的暴露部分的内表面被加热到高于热塑性材料的玻璃化转变温度以使内表面熔融,同时外表面为套筒的暴露部分提供支撑 。 然后将加热的暴露部分成形为圆锥形,例如通过加热外表面,停止心轴的旋转,并将压力施加到锥形暴露部分以形成头部热塑管。 所制造的头管具有主体部分,肩部和颈部,没有任何接缝,所有这些都由起始的热塑性挤出拉伸的套筒形成。
