Abstract: A container closure is provided with internal threads which compensate for variations in the external threads of a container neck onto which the container closure is to be threaded. The container closure threads extend inwardly toward the central axis of the closure and, in the illustrative embodiment, define an angle of 30 degrees with respect to the central axis. The closure thread tapers inwardly as it extends toward the central axis and is generally flexible but is sufficiently rigid to prevent the lower thread from contacting an immediately higher thread during flexing of the threads.

Abstract: A self-sealing flange assembly includes an elliptical shaped hole in a blind wall, the greatest diameter of which is larger than the smallest diameter of an elliptical shaped inner flange. Attached at a right angle to the surface of the flange is an internally or externally threaded nipple, bushing, stud or fastener. An annular groove located on the circumference of the flange contains a sealing means. At least one dimple at an apex of the elliptical flange locates the flange in situ when it is inserted through the wall opening and positioned thereon. An outer elliptical washer type element is tightened against the outer wall by rotation of a nut on the threads of the nipple, bushing, stud or rotating the bolt in the fastener, compressing the elliptical inner flange and sealing means against the inner wall forming a one piece leak proof assembly. The dimple used to locate the flange in situ also prevents rotation of the inner flange during the tightening process.

Abstract: The disclosure relates to an explosives storage container for absorbing and containing the blast, fragments and detonation products from a possible detonation of a contained explosive. The container comprises a layer of distended material having sufficient thickness to convert a portion of the kinetic energy of the explosion into thermal energy therein. A continuous wall of steel sufficiently thick to absorb most of the remaining kinetic energy by stretching and expanding, thereby reducing the momentum of detonation products and high velocity fragments, surrounds the layer of distended material. A crushable layer surrounds the continuous steel wall and accommodates the stretching and expanding thereof, transmitting a moderate load to the outer enclosure. These layers reduce the forces of the explosion and the momentum of the products thereof to zero. The outer enclosure comprises a continuous pressure wall enclosing all of the layers.

Advantageously, the expandable, externally-threaded collar member can be applied to the top, neck portion of the container by merely sliding said collar member over the rim of the container. Once in place, the container can then be sealed by applying the internally-threaded cap member to the externally-threaded collar member.

Abstract: A pressure tank connector is described which is formed integral with the cylindrical side wall portion of the tank so that such connector deforms and acts as a safety valve when the fluid pressure within the tank exceeds a predetermined pressure. The deformed connector produces a space between it and an insert member which enables the pressurized liquid or gas within the tank to slowly leak out through such space. In the preferred embodiment, the connector includes a threaded cylindrical connector portion joined by a conical projection portion to the side wall of the tank. The fluid escapes from the tank through a space formed between the threads of such connector and those of an external fitting screwed into such connector.
