Methods of Closure Thread-engagement types (...) Press-Twist. The "press-twist" is another closure which attains its threads on the capping line. Primarily used for baby foods it also provides closure for sauces, gravies and juices. Applied in a steam atmosphere, the plastisol side gasket in the heated cap forms thread impressions when pressed against the glass finish. As it cools, permanent impressions are formed in the compound so the cap can be twisted to open and reseal similar to a CT cap.

OBS

The term "press-twist" must be considered as familiar.

OBS

Although the terms "closure" and "cap" may be seen as different when standing alone, we think they should be recognized as synonyms when properly qualify.
