Problems solved by technology

[0009] None of these documents overcomes the problems of WO2008 / 001078, and therefore there is nothing in the art that represents a robust and reliable valve to refill simulated cigarettes at the relatively high pressures they require

Embodiment Construction

[0046] The simulated smoking device comprises a simulated cigarette 1 as described in WO 2009 / 001078, except for its refill valve. The simulated cigarette 1 has a reservoir for the inhalable composition, an exhalation valve and a refill valve as described below. Apart from the refill valve, the cigarette will not be further described here. Further modifications of the simulated cigarette device are disclosed in the applicant's previous applications WO 2010 / 073018, WO 2011 / 015825, WO 2011 / 015826 and WO 2011 / 117580.

[0047] The composition of the reservoir is described in WO 2009 / 001085. Further details are provided in WO 2014 / 033437.

[0048] The remainder of the simulated smoking device is the refill device. This includes the main housing part 2, which is a plastic moulding. It is surrounded by a thin card sleeve 3 on which various information, such as promotional information, is printed. The size of the housing is preferably similar to the size of a cigarette pack, and ...

Abstract

A pressurized refill canister (5) comprising a reservoir (31) of a composition comprising a propellant and nicotine or a pharmaceutically acceptable derivative or salt thereof. The reservoir (31) is at a pressure greater than 400 kPa at 20°C. The refill outlet valve (20) comprises a tube (6) having an axial hole (24) open at the axial end furthest from the reservoir (31 ) to provide an axial direction The upper outlet discharges the composition. When no external force is applied, the tube is biased to a closed position by a first elastic member with a spring force greater than 10N, from which the tube (6) can overcome the action of the first elastic member to move into the dispense position to open the flow path from the reservoir to the outlet.

Description

technical field [0001] The present invention relates to a pressurized refill tank having an outlet valve. In particular, the pressurized refill tank has been designed for refilling simulated cigarettes such as disclosed in WO 2009 / 001078. However, the pressurized refill tank may also be used in other products requiring pressurized gas refilling. Background technique [0002] In WO 2009 / 001078 a simulated cigarette is proposed, the size of which is similar to that of a conventional cigarette. The cigarette has a reservoir for receiving pressurized gas comprising a propellant. The reservoir has a breath actuated valve at one end (this is described in more detail in WO2011 / 015825, WO 2011 / 015826) and a refill valve at the other end. [0003] The refill box has the shape and size of a normal cigarette box, is provided with a cylinder of refill gas and has a fill valve arranged to match the refill valve in the cigarette to periodically refill the cigarette. [0004] As descri...
