Abstract: The child resistant safety closure is one that uses a common single start thread on the neck of a container and on a closure. In conjunction with this single start thread there is a single mating projection on the neck and on the closure. These mating projections are in an interference fit until the closure is distorted so that the closure bows outwardly in the region of the projections whereby the projection on the neck and the projection on the closure can pass by one another. The distortion is enhanced by having the plastic of the closure in the area of the projection of a decreased thickness and the neck having flattened portions to provide for a easy distortion of the closure. By the use of a single start common thread and one projection the same closure can be used for containers requiring a safety closure and those not requiring a safety closure. The difference will solely be in the neck finish of the container or on the inner surface of the closure. When the container is to have a safety closure the neck finish has a projection to mate with a projection on the closure. In the instance where the container is not to have a child resistant safety closure either the closure will not have a projection or the neck of the container will not have a projection. In such a case the closure can be freely removed from the container.

Abstract translation: 防儿童安全关闭是在容器颈部和封闭物上使用通用的单一启动螺纹。 结合这个单一启动螺纹，在颈部和闭合件上有一个单一的配合突起。 这些配合突起处于过盈配合状态，直到封闭件变形为止，使得封盖在突出部分的区域内向外弯曲，从而颈部上的突起和封闭件上的突起可以彼此通过。 通过在突出部分的区域中使封闭物的塑料具有减小的厚度并且颈部具有扁平部分以提供闭合件的容易变形来增强变形。 通过使用单个起始公共螺纹和一个突出部，相同的闭合可用于需要安全闭合的容器和不需要安全闭合的容器。 该差异将仅在容器的颈部或闭合件的内表面上。 当容器具有安全关闭时，颈部处理器具有与封盖上的突起配合的突起。 在容器不具有防止儿童安全关闭的情况下，封闭件将不具有突起，或者容器的颈部将不具有突起。 在这种情况下，封闭件可以从容器中自由地移除。
