A method for coupling a tube to a tube fitting includes radially outwardly expanding a tubular compression collar from a constricted state to an expanded state, the compression collar having a throughway extending there through and being made of a resiliently flexible material. An end of the tube is inserted within the throughway of the expanded compression collar, the tube bounding a passageway. A tube fitting is inserted within the passageway of the tube. The compression collar is allowed to resiliently rebound back towards the constricted state so that the compression collar pushes the tube against the tube fitting.

A component comprising a first concentric element and a second concentric element is disclosed. The first and second concentric elements are positioned relative to each other in the positions in which they are to be bonded together. The first concentric element comprises a first bonding portion (48) with a first bonding face (50), and the second concentric element comprises a second bonding portion (58) with a second bonding face (60), a first passage (62), and a second passage (64). The second bonding portion (58) partially surrounds the first bonding portion (48) and the first and second bonding faces (50, 60) face each other. The first and second bonding faces (50, 60) comprise a first and second void face (56, 61) respectively. Collectively the first and second bonding faces (50, 60) comprise an alpha plug (52) having an alpha plug face, a beta plug (54) having a beta plug face, an alpha bearing face, and a beta bearing face, in which the alpha plug face is in sliding contact with the alpha bearing face and the beta plug face is in sliding contact with the beta baring face, the alpha plug (52) is integral with one of the first or second void faces (56, 61) and the alpha bearing face is integral with the other of the first or second void faces (56, 61), the beta plug (54) is integral with one of the first or second void faces (56, 61) and the beta bearing face is integral with the other of the first or second void faces (56, 61), and the alpha and beta plugs (52, 54) and first and second void faces (56, 61) collectively define a void. The first and second passages (62, 64) each extend through the second concentric element from a mouth which opens onto the void to a mouth in an accessible surface of the second concentric element.

A liquid storage bottle includes a bottle body having a resin-made first cylindrical part at one end, the first cylindrical part having an opening at its front end, and a tubular nozzle for pouring out the liquid contained in the inside of the bottle body by way of the opening, the tubular nozzle having a resin-made second cylindrical part bonded to the bottle body. The inner peripheral surface of the second cylindrical part is welded to the outer peripheral surface of the first cylindrical part. The outer peripheral surface of the first cylindrical part is provided with an annular groove extending in the circumferential direction and the annular groove is made to contain a part of the resin that is molten during the bonding operation.

A method for joining composite rods with tubular shape without expensive, machined connectors and without compromising the structural integrity of the composite rod includes internal and external collars applied to the ends of the composite rod and deformed via unidirectional compressive load applied by a clamp in the radial direction of the composite rod cross-section. The resulting plastic deformation of the metal collars and composite rod interlock those components to support both compressive and tensile loads. The deformed metal collars are easily joinable to other components via off-the-shelf hardware.

Exposure of a leftover material at a cartridge that forms a vapor product is prevented. There is provided a cartridge that is assembled in a part of a vapor product that includes a heating element for heating an aerosol source. The cartridge includes a first component and a second component, at least one of which being formed of resin, and a connection section whose one end is connected to the first component and whose another end is joined or welded to the second component. The second component includes a facing surface that faces the first component, and an outermost edge of the facing surface. The other end of the connection section is joined or welded to the facing surface of the second component, at a position away from the outermost edge.

A leftover material is prevented from being generated from a part, of a cartridge that forms a vapor product, where positioning is performed. There is provided a cartridge that is assembled in a part of a vapor product that includes a heating element for heating an aerosol source. The cartridge includes a first component and a second component, at least one of which being formed of resin, a connection section that extends between the first component and the second component, with one end connected to the first component and another end connected to the second component, and a guide section that extends from the first component, and that is not joined or welded to the second component. The second component includes a receiving section where the guide section fits.

A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.

Construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material may be provided in the inner liner layer.

Herein is described a pressure resistant shell for stabilizing a welding seam of a weldable tubing as well as a method of using it.

The present disclosure relates to systems, apparatuses, and methods for assembling cartridges for aerosol delivery devices. A system may include assembly cells each including an assembly track and assembly carriages that ride thereon and which engage components of partially-assembled cartridges. A transfer apparatus may transfer partially-assembled cartridges between the assembly cells. In another example system, cartridges may be assembled on platforms on a rotary track. The platforms may include assembly grippers with sequentially-opening clamps configured to receive the components of the partially-assembled cartridges. Related methods are also provided.
