摘要： A bung comprises a deformable member with a generally cylindrical middle portion generally coinciding with the bunghole when inserted, and upper and lower frusto-conical ends which increase in diameter as each end extends from the middle portion. The middle portion is preferably of a size less than the hole to facilitate insertion of bung into and removal from the bunghole. Where the hole is tapered, the middle portion is similarly tapered. The spool-like shape of the stopper helps to prevent unintentional disengagement of the bung from the hole and to prevent overinsertion of the bung into the hole. The bung may further comprise one or more pull tabs to facilitate removal. The bung may define a bore to allow gas pressure to escape from the container, thus acting as a stopper. A rigid annular insert at the opening of the throughbore prevents deformation of the circular shape of the opening.

摘要翻译： 栓包括可变形构件，其具有大致圆柱形的中间部分，当插入时大致与孔洞重合，并且当每个端部从中间部分延伸时，直径逐渐增大的上部和下部截头圆锥形端部。 中间部分优选地具有小于孔的尺寸，以便于将栓塞插入和移出孔。 在孔是锥形的情况下，中间部分也是锥形的。 止动器的线轴形状有助于防止栓从孔中的意外脱离，并防止栓塞过孔插入孔中。 栓可以进一步包括一个或多个拉片以便于移除。 栓可以限定孔，以允许气体压力从容器中逸出，从而用作塞子。 在通孔的开口处的刚性环形插入件防止了开口的圆形变形。
