The multilayer container includes a container body having a multilayer structure and a multilayer head of the container. The multilayer body of the container has at least one barrier layer connected, on one side, to at least one thermoplastic layer and heat sealed in a longitudinal overlapping joint formed of the edges of these layers. The body has its external surface covered with a polymeric coating, and the multilayer head of the container includes at least one non-metallic barrier layer connected, on one side, to at least one thermoplastic layer and is wholly extruded in the co-extrusion process. The essence of the invention is also a method for producing such a container.

A guard for providing a cut-resistant pathway through a body orifice or incision to circumferentially protect tissue at the margin is provided. The guard is made of flexible, cut-resistant mesh material having a plurality of interwoven thermosetting filaments. The guard has a central lumen and at least one flared end. The flared end, which serves to anchor the guard in the body opening, is deformable into a reduced configuration to facilitate its insertion and removal. The layer of mesh stretches laterally to increase the diameter of the central lumen. The flexibility and expandability of the guard allows the guard to conform to body openings of different sizes. The guard may include a drawstring to cinch the flared distal end from the proximal end. The guard is thermoset with the flared distal end that is biased to spring back to its normal, undeformed configuration when released from a deformed configuration.

Described is an apparatus for heating end portions of pipes made of thermoplastic material, comprising an internal heating element, designed to be inserted at least partially inside an end portion of a pipe made of thermoplastic material for heating an inner cylindrical surface of the portion, the heating element comprising at least one infra-red ray radiation unit which has an operating zone designed to face at least partially the inner cylindrical surface, the operating zone extending longitudinally along a predetermined direction, parallel to a central axis of the pipe to be heated.

Described is a method for chamfering the end of a pipe (2) made from thermoplastic material, comprising the following steps: localised and circumferential heating of an axial portion (3) of the pipe (2) at a predetermined temperature; plastic deformation of the heated axial portion (3) using a tool (4) for forming a chamfer on the axial portion (3).

An embodiment of a portable tube flaring system for flaring a flexible plastic tube end includes a hand-held wand with a heating element for heating a tube heater receptacle, which provides direct contact heating of the tube end about the entire outer periphery of the tube end. A mandrel device is configured for manual insertion into the heated tube end by the user after the tube end is removed from the wand and heater receptacle. A power/control unit is connected to the wand by a wiring bundle to provide electrical power to the heating element, and to optionally provide a visual and/or audio signal to the user for indicating when the tube end should be removed from the wand receptacle, and thereafter, when the mandrel may be removed from the tube end after sufficient cooling or curing time. The system may be carried by a person.

An expansion tool includes a housing, a motor supported in the housing, and a plurality of jaws, a mandrel moveable relative to the housing between a retracted position and an extended position, a drive mechanism configured to convert rotational input from the motor into translational movement of the mandrel between the retracted position and the extended position, and an actuator movable between a first position and a second position. The mandrel is engageable with the jaws to expand the jaws in response to movement of the mandrel to the extended position. The drive mechanism is operable in a high speed configuration when the actuator is in the first position and a low speed configuration when the actuator is in the second position.
