Problems solved by technology
Also, since the metering chambers are much smaller than cigarettes, they are not suitable for refilling simulated cigarettes
So refilling requires pressing the cigarette against the valve multiple times, which won't work in practice if the cigarette needs to be vented before filling
[0009] None of these documents are able to overcome the problems of WO 2008 / 001078, so the prior art does not propose a robust and reliable valve capable of refilling simulated cigarettes at the relatively high pressures required for them

Embodiment Construction
[0042] The simulated smoking device comprises a simulated cigarette 1 as described in WO2009 / 001078 except for the refill valve of the simulated cigarette 1 . The simulated cigarette 1 has a reservoir for inhalable composition, a breath operated valve and a refill valve as described below. Apart from the refill valve, the cigarette will not be further described here. Further modifications to the simulated cigarette device are disclosed in our own earlier applications WO2010 / 073018, WO2011 / 015825, WO2011 / 015826 and WO2011 / 117580.
[0043] The composition of the reservoir is described in WO2009 / 001085. Further details are provided in WO2014 / 033437.
[0044] The remainder of the simulated smoking device is a refill device. The refill device comprises a main housing part 2 which is a plastic moulding. The main case part 2 is surrounded by a thin card sleeve 3 on which various information such as promotional information is printed. The dimensions of the housing are preferably ...

Abstract
A pressurized refill tank (5) comprising a reservoir (31) of a composition comprising a propellant and a non-metered refill outlet valve (20) comprising a stem (6 ), the lever can be displaced from the first position to the dispensing position against the action of the elastic member. Said rod (6) comprises a blind hole open at the outlet end and closed at the opposite end and a transverse hole (27) in the side wall of said rod (6) leading to said blind hole. Said refill outlet valve further comprises an annular seal (22) surrounding said stem (6), whereby in said first position said transverse bore (27) does not communicate with the interior of said tank, but In the dispensing position, the transverse hole (27) is arranged to move relative to the seal (22) inside the canister to open the The flow path from the blind hole to the outlet port.
Description
technical field [0001] The present invention relates to a pressurized refill tank having an outlet valve. The pressurized refill tank is especially designed for refills for simulated cigarettes such as disclosed in WO 2009 / 001078. However, the pressurized refill tank can also be used in other products requiring pressurized gas refilling. Background technique [0002] In WO2009 / 001078 a simulated cigarette is provided which has similar dimensions to conventional cigarettes. The cigarette has a reservoir to hold a pressurized gas comprising a propellant. The reservoir has a breath actuated valve at one end (as described in detail in WO 2011 / 015825 and WO 2011 / 015826) and a refill valve at the opposite end. [0003] A refill pack having the shape and size of a normal cigarette pack is provided with a cartridge of refill gas and has a fill valve arranged to cooperate with a refill valve in a cigarette to periodically refill the cigarette. [0004] As described in WO2009 / 0010...
