Abstract: Door-barring lock apparatus has a bar member rotatably mounted to the wall near the doorway. When in a transverse or generally horizontal position, this bar member projects into the doorway for engaging the inside of the door near the opposite margin from the hinges for advantageously, positively barring the door against opening inwardly. By manipulation of a handle located inside of the building near the bar member, a person inside of the building can de-couple the bar from a locking rod extending through the wall to the outside of the building. Such de-coupling enables the person inside of the building to rotate the bar into an upright position for freeing the door to allow the door to be opened, regardless of whether this rod is locked against rotation. A lock assembly accessible from the outside of the building normally serves to lock the rod against rotation for normally locking the bar member in its transverse door-barring position.

Abstract: A method of forming a nozzle outlet in the stretchable, flexible wall for a container by providing rigid inner and outer sleeves adapted to mate together in taper-interlocked relationship by stretching a portion of the wall around the inner sleeve and becoming sandwiched between the mated sleeves. The inner sleeve has an outlet passage extending therethrough and has an exterior surface which tapers at a small angle, the outer sleeve having an interior surface tapering at a corresponding angle so the sleeves will engage together in a wedging-locking relationship with the stretched wall portion sandwiched and protected between them.
