A fluid transfer connector or adapter for coupling to a container or pharmacy bottle for facilitating the transfer of fluid or medicine from the bottle to a syringe, or from the syringe to the bottle. Optionally, an additional connector can be provided for coupling the fluid transfer connector to the syringe.

A hinge assembly is mountable on first and second large drums or barrels so that the first drum or barrel can be lifted or raised to drain liquid from the first drum or barrel into the second drum or barrel. The hinge assembly includes inner and outer plates which clamp to the rim of each drum to secure the hinge assembly to the drums. The plates may be adjustable to fit different rim dimensions. The hinge assembly does not penetrate, damage or alter the drums. An optional handle can be mounted to the hinge assembly to facilitate lifting of the first drum.

A liquid direct injection assembly includes a direct injection supply kit to mix liquid components into a mixture and deliver the mixture to a treatment device. The supply kit includes liquid component containers that each include an elongated flexible bladder and a discharge nozzle to discharge a corresponding liquid component from the bladder. The supply kit also includes metering bodies each defining a metering orifice to control a flow rate of the corresponding liquid component from the bladder. The liquid direct injection assembly also includes a container tray configured to removably support a liquid component container.

A line coupling having a housing which has a tube connection piece and a housing head. A passage duct extends from a first opening, which is formed by the tube connection piece, to a second opening, which is formed by the housing head. A tube connection structure is arranged in the passage duct. The tube connection structure is connected in a form-fitting manner via first coupling means to a first end of an inner tube which extends out of the housing head through the second opening. The section of the passage duct between the first opening and tube connection structure and inner tube form a flow duct for fluid. A container is also disclosed having a container housing which forms a container hollow space and a container opening. The container opening is formed by an outwardly projecting connection piece, and has a line coupling.

The disclosure provides an electronic cigarette, wherein the electronic cigarette comprises an upper-cover assembly and a lower-cover assembly. The upper-cover assembly and the lower-cover assembly are cooperated to together form an oil-storing chamber. The lower-cover assembly comprises a connecting element, a bottom cover and a sealing element detachably connected to the bottom cover. One end of the connecting element is connected with the bottom cover, and the other end of the connecting element is connected with the upper-cover assembly. The bottom cover defines an oil-refilling hole. The connecting element defines a through hole communicating with both the oil-refilling hole and the oil-storing chamber. When the sealing element is connected with the bottom cover, the sealing element extends through the oil-refilling hole and is accommodated in the through hole. The electronic cigarette of the present disclosure has a simplified structure and is able to be refilled with oil conveniently, avoiding oil-leakage.

An electronic cigarette vaporizer is not dis-assembled for filling with e-liquid, but is instead filled from a user-replaceable e-liquid cartridge. The vaporizer includes a front section comprising a wick and heating assembly but no e-liquid cartridge, the front section being removably fitted to a body of the vaporizer to enable a replacement front section to be used once the original wick or heating element starts to degrade, that replacement front section being supplied to the end-user with no e-liquid in it.

The invention is an electronic cigarette vaporizer system operable in a discrete mode to reduce the amount of vapor produced by a vaporizer that forms part of the system, compared to a normal mode. The discrete mode causes the vapor produced to be less visible or noticeable, compared to a normal mode.

An electronic cigarette vaporizer that includes a heating element and further includes or co-operates with an electronics module that (i) detects characteristics of the delivery of power, current or voltage to the heating element and (ii) determines if those characteristics are associated with degradation of the heating element. A characteristic that is associated with degradation of the heating element is an increase or other change in the heating element resistance. The heating element resistance can be established by the electronics module sending a test current through the heating element that is sufficient to enable a measurement of resistance to be made.

An electronic cigarette vaporizer includes a heating element for heating an e-liquid and a microcontroller; the microcontroller determines the type and/or characteristics of the e-liquid being used and uses that as an input to automatically control the power delivered to the heating element to heat the e-liquid in a manner suitable for that specific type of e-liquid, or e-liquid with those characteristics. The e-liquid can be supplied from a cartridge and that cartridge then includes a record of the type of e-liquid stored in the cartridge and/or its characteristics and the microcontroller reads that record or is provided data from that record. A variable for the type of e-liquid and/or its characteristics is the water content of the e-liquid.
