Abstract: A thermoformed screw type closure of semi-rigid material having a plurality of projections located between the uppermost point of the thread and the top of the closure which is recessed to lie inwardly of the root of the thread to engage the neck of a container onto which the closure is to be applied. The projections deform upon screwing down of the closure onto the container producing a good seal and fit and preventing the closure from backing off. A die is also disclosed for making closures of the foregoing type which utilizes the recessed portions of the closure as an aid in removing the closure from the die.
Abstract translation: 半刚性材料的热成形螺钉型封闭件，其具有位于螺纹的最上部点和闭合件的顶部之间的多个突起，该突起凹入以位于螺纹根部的内侧以与容器的颈部接合， 封闭将被应用。 当将密封件拧紧到容器上时，突起变形，产生良好的密封并配合并防止封闭件脱落。 还公开了一种用于封闭上述类型的模具，其利用封闭件的凹陷部分作为帮助从模具移除闭合件。
