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.

A liquid container includes a liquid container body and a protection member that is attached to the liquid container body. The liquid container body includes: a liquid supply port; a plurality of contact parts that are to be in contact with an electrode part; a first engagement-target part; and a second engagement-target part. The protection member includes: a sealing part that faces the liquid supply port; a first engaging part that engages with the first engagement-target part; and a second engaging part that engages with the second engagement-target part. A first direction denotes a direction in which the sealing part faces the liquid supply port, a second direction denotes a direction that is orthogonal to the first direction and is a direction from the liquid supply port to the plurality of contact parts, and a third direction denotes a direction that is orthogonal to the first direction and the second direction. The plurality of contact parts viewed in the first direction are located between the first engaging part and the second engaging part in terms of the third direction.

A lid to protect connectors of hydraulic and gasoline lines during its transportation, that has the ability to expand and adapt itself to many different connectors with different shapes and sizes, but still keeping its ability to remain properly installed during its working life, and at the same time to be able to be removed from the connector whenever necessary, as long as it is used within its designed rage of performance. The lid is different from all the existing connectors in the actual state of the art, which can only be used with the specific connector they were designed for.

A safety apparatus for fitting to a free end of an elongate member, for example a reinforcing bar, has a sleeve portion defining a receiving space for receiving a free end of the member and providing an opening of the receiving space to allow insertion of the member from a first end of the apparatus, and a covering portion which provides a barrier to prevent passage of the member through a second end of the safety device. The safety apparatus may have a gripping part which is resiliently deformable, so that it is resiliently deformed by insertion of the member so as to securely grip metal member, and so that it returns to substantially its non-deformed shape upon removal of the metal member. The receiving space may be tapered.

A temporary protector of a male end of a component of a threaded tubular connection, including externally at least one threading and a free end part. The protector includes a coupling to protect at least part of the external threading and the free end part and including a threading that can engage with the threading of the male end, and a sealing device configured to be placed in contact with the component, at least in a part located downstream of the external threading of the male end, and to provide a seal downstream of the external threading. The sealing device includes a portion of small diameter including an internal sealing surface that can interact hermetically with an external surface of the body, and a portion of large diameter including an internal sealing surface interacting hermetically with an external surface of the coupling, the sealing device being radially elastic.
