A universal thread protector is provided for protecting either of the pin and box ends of a pipe. The thread protector has a cap with an open end the closed end. A seal element is positioned within and adjacent to the open end of the cap. A ring member is positioned against the seal element between the seal element and the closed end of the cap. Bolts are provided having an end positioned against the ring member. The bolts are movable from an unactuated position to an actuated position wherein the bolt applies a force against the ring member when in the actuated position. As such, the ring member pushes against the seal element so as to deform or compress the seal element against the outer diameter of the pipe positioned within the cap. A method of protecting the threaded ends of pipe is also disclosed.

A protective end cap has a sleeve portion and a distal portion connected to an end of the sleeve portion. The sleeve portion includes one or more recessed portions in which an elastomer material is received and extends above an interior surface of the sleeve portion. The distal portion defines an exterior surface and an interior abutment surface that is substantially perpendicularly disposed relative to the interior surface of the sleeve portion. When the sleeve portion receives a first length of a rod member, the rod member abuts the abutment surface and the elastomer material is compressed between the recessed portion and a side surface of the rod member to frictionally retain the rod member within the sleeve portion.

A thread protector comprises a hollow cylindrical body with a substantially closed end and a threaded inner annular wall extending from the substantially closed end. An annular ring extends inwardly from the substantially closed end. The annular ring has a sloped wall which is spaced-apart from and faces the threaded inner annular wall.

A magnetic flange protector for protecting the surface of a flange. The magnetic flange protector includes a planar member having an upper surface and a lower surface, a handle secured to the upper surface of the planar member, and a magnet secured to the lower surface of the planar member. The handle has a first end and a second end, wherein each end is secured to the upper surface. The magnet is secured to the lower surface of the planar member within a recessed area, thereby allowing the lower surface to rest flush against and cover a gasket face surface of a flange. In an alternate embodiment, the planar member is circular, wherein a concentric annular seal is secured to the lower surface, and the handle is arcuately shaped.

A thread protector for use with a threaded end of a tubular member comprises a first end having an opening with an inside diameter, a second end, and an interior having an inside diameter that is substantially the same as the inside diameter of the opening. The interior is adapted to accept and surround the threaded end. The thread protector may be actuated between a locked and an unlocked configuration. When the thread protector is in the locked configuration, a portion of the inside diameter is reduced, as compared to when the thread protector is in the unlocked configuration, so as to securely mount the tread protector to the threaded end.

This tubular member thread protector generally comprises an outer member capable of rotation in a first direction about an axis and an inner member coaxially integrated within the first member and capable of rotation in an opposite direction. The inner member comprises a flexible annular sleeve having an outer surface and an interior surface defining an interior annular space capable of receiving the tubular threaded end. One or more camming surfaces are disposed about the inner sleeve outer surface. The outer member comprises a generally annular structure having a closed end, an open end, an outer surface and an inner surface. One or more raised camming members are disposed about the outer member inner surface and are aligned with sleeve camming members during rotation, the outer member camming members press against the inner sleeve camming members to radially compress the sleeve inner surface against the threaded member.

A device for keeping canned drinks cold includes a tube having a diameter only slightly larger than the diameter of a can. A disclosed tube is long enough to accommodate six cans stacked end-to-end. At least one end of the tube has a removable cap. An insulating foam encases a major portion of the tube to provide thermal insulation and, optionally, to enable the device to float.

According to one aspect, a non-roll end sleeve is configured to be disposed on a seamless cylindrical paper tube, the non-roll sleeve having a rectangular cross-section perpendicular to a central axis of the cylindrical paper tube when disposed on the cylindrical paper tube. According to another aspect, a container includes a seamless paper tube having at least one end provided with a shape in cross-section generally having N sides, where N is an integer selected from 3 to 8, which at least one end is closed by flaps of material between openings cut into the at least one end that have been folded inwardly and secured in place to form an end closure.
