PIPE END CLOSURE USABLE AS THREADED STOPPER OR CAP |
摘要 |
This invention relates to a protective closure for threaded or non-threaded tubular articles or projections. This protective closure comprises a hollow cylindrical member having an open and a closed end and with at least one internal and one external circularly-shaped plateau. Joined to the open end of the cylindrical member is a flexible sleeve which can be folded back over the article which is to be protected. This folding ability of the sleeve serves as a locking device to retain the protective closure on certain tubular-shaped articles or projections. A number of helical threads can also be formed on each of the plateaus to provide a further locking device when the protective closure is used to protect a threaded article. |
