Definitions

  • the present invention relates to the field of tobacco, more specifically to the electronic cigarette which produces vapour.
  • Smoking devices which heat rather than burn vaporisable material, such as tobacco-containing substrate, to create a vapour for inhalation are becoming popular. They generally comprise a heat source powered by gas or electricity and a chamber for receiving a plug of vaporisable material or a disposable capsule containing a vapour-generating product. When in use, the plug or capsule is inserted into the device and heated by the heat source to generate a vapour for inhalation.
  • patent document US 2006174901 discloses a capsule containing additive materials such as flavour components.
  • the sealed capsule is subjected to external force, such as squeezing, by a smoker prior or during smoking of the cigarette in order to release at least a portion of the additive material from the one or more capsules and expose the additive material to mainstream smoke passing through the filter.
  • a smoking article including a capsule configured to release a liquid, preferably water, as an additive material providing modified sensory attributes.
  • the capsule may be a non-directional capsule or preferably a directional capsule.
  • a directional capsule is configured to break at predetermined rupture region and is adapted to direct liquid release into a desired direction or towards a particularly desired region of the smoking article.
  • capsules often have several drawbacks. For instance, some capsules are structurally integrated with the device and they are not easily replaceable or disposable. Other capsules may be disposable upon consummation; however, the volume of the liquid is either too little or too much to suit according to the needs of different users, as some users may have to carry additional capsules to replace the used capsules.
  • present invention relates to a disposable capsule for use in a vaping device, wherein the capsule having a housing for containing liquid substance, comprising a male connector provided on one side of the housing and a female connector provided on another side of the housing, wherein the male connector and the female connector comprises a surface to mate with a female connector and a male connector of other capsules, respectively;
  • the female connector comprises a substantially circular base area having an accepting lip element having a primary sealed opening;
  • the male connector comprises a substantially circular base area with a dome structure having a primary sealed opening; wherein when a male connector of a capsule and a female connector of another capsule, or vice versa, are mated, the primary sealed openings are ruptured, thereby allowing liquid substance of the capsules to communicate.
  • present invention relates to a plurality of disposable capsules assembly according to the present invention interconnected to form a capsule assembly.
  • the male connector and the female connector are provided on an opposite side of the disposable capsule. This allows the capsules to be connected longitudinally. As vaping device generally has an elongated body, the battery of capsules can thus be fitted into the body of the vaping device.
  • two, three or four pairs of male connectors and female connectors are provided to the capsule, wherein each pair of the male connector and the female connector are arranged on an opposite side of the capsule.
  • the accepting lip of the female connector comprises a surface and a periphery complimentary to the male connector such that when the female connector and the male connector are mated, the accepting lip of the female connector surround the male connector in a water-tight manner.
  • This configuration prevents liquid from leaking through the connection points.
  • the capsule especially the male and female connectors are made of elastomeric material, this allows leak-proof connection to be established.
  • At least a valve is provided to the capsule.
  • the valve not only prevents liquid leakage, but it can also be served as a check valve to prevent backflow of the liquid.
  • the at least one valve is provided to the male connector and/or the female connector and/or nipples of the capsule.
  • the valve is preferably provided to the male connector and/or the nipple in the protruding part as this allows an easy installation of the valve.
  • the valve is a flanged duckbill valve.
  • the accepting lip is a flanged duckbilled check valve.

  • the opening of the female connector is a tearable opening.
  • the opening of the male connector is a pressure-sensitive opening.
  • a tobacco-containing substrate can be any compound, mixture, particle matter, material and/or solution that contains and/or carries a constituent of tobacco, either artificially included or naturally contained in tobacco, e.g. tobacco, tobacco particles, tobacco flavor and/or nicotine.
  • the liquid substance according to the present invention may comprises the tobacco-containing substrate.
  • vaping device refers to a device for producing a vapour and/or aerosol that is intended to be heated rather than combusted in order to release volatile compounds that can form a vapour and/or an aerosol.
  • vapour refers to a material, upon heating, capable of releasing volatile compounds, which can form a vapour and/or an aerosol.
  • the vapour generated from liquid substance described herein may be visible or invisible and may include aerosol (for example, fine particles of substances, which are in a gaseous state, that are ordinarily liquid or solid at room temperature) as well as gases and liquid droplets of condensed vapours.
  • An electronic cigarette (e-cigarette) or similar devices like electronic pipes or heat-not-burn devices, as referred to in the present invention, are not particularly limited, and may be used to provide a user with an aerosol to inhale. It can, according to certain embodiments, comprise a mouthpiece, a heater, a receiving portion, e.g. a pod, stick, capsule and a casing.
  • FIG. 1A shows an exemplary of a capsule 20 according a first embodiment.
  • the capsule 20 can be provided in a cylindrical shape, having a male connector 12 and a female connector 14 provided on an opposite location of the capsule 20.
  • the male connector 12 is a protruding structure whereas the female connector 14 is an acceptor or a concave structure for accepting the male connector 12.
  • the female connector 14 is situated within the capsule 20.
  • the capsule 20 comprises a housing, wherein liquid substance is contained within.
  • the housing of the capsule 20 can be made of a plastic material such as polyethylene or silicone material in order to ensure for lightweight. Alternatively, biodegradable material can be used to make the housing such as said capsule can be degraded easily than plastic material.

  • a sealed opening 15 is provided on the surface of each of the male connector 12 and the female connector 14.
  • the sealed opening 15 may be a weakened point which is easily ruptured upon distortion.
  • the male connector 12 and the female connector 14 comprises a complimentary surface and shape to mate with a female connector and a male connector of other capsules, respectively, hence no liquid is leaked from the two connected capsules 20.
  • their sealed openings 15 are ruptured or broken due to the distortion force, thus allowing the liquid substance contained in the two capsules to communicate and flow freely through the sealed openings 15.
  • the female connector 14 comprises a substantially circular base area having an accepting lip element having a primary sealed opening 15.
  • the male connector 12 comprises a substantially circular base area with a dome structure having a primary sealed opening 15.
  • the primary sealed openings 15 are ruptured, thereby allowing liquid substance of the capsules to communicate.
  • the sealed openings 15 may preferably has a thickness of less than 0.5 mm, preferably less than 0.2 mm to allow easy rupture. The sealed opening 15 once being ruptured, a permanent opening will be created and thus the capsule 20 is no longer watertight.
  • multiple capsules can be stacked and connected with each other, like Lego pieces.
  • an airtight connection between the male connector 12 and the female connector 14 can be created, thus ensuring the liquid substance within the capsules 20 remained inside the capsules 20.
  • FIG. 2 shows an exemplary mode of operation of the capsules 20 with the vaping device 200, wherein a plurality of capsules 20 are loaded into the vaping device 200.
  • the vaping device may comprise a mouth piece 120, a power supply 220, a controller 240, an electric heater 160 and channels 180 for directing liquid substance from the capsule 20 towards the electric heater 160 such that the liquid substance can be heated to be vaporized.
  • a wick-like element may be incorporated with the electric heater 160 such that liquid substance from the capsules 20 are drawn constantly out of the capsules and fed towards the electric heater 160.
  • the vaporized liquid substance will be channelled towards the mouth end (see arrow head), passing through a mouth piece 120 and be inhaled by the user.
  • the capsules 20 are loaded into a capsule storing portion where typically between two and five capsules 20 of the present invention can be loaded therein.
  • the capsule 20 according to the present invention may be provided in different length such that the right total length of the capsules can be loaded into the capsule storing portion of the vaping device.
  • the vaping device comprises a capsule storing portion of at least 3 cm where at least one removable capsule or cartridge can be loaded therein.
  • FIG. 3A and 3B demonstrate a closed-up view of the internal of the male connector 12 according to an exemplary of the present invention, wherein a valve 33 is provided within the male connector 12.
  • the valve 33 is provided as an additional protection from leaking when the male connector 12 and the female connector 14 are mated.
  • the valve 33 can be situated within and accepted by the female connector 14.
  • the valve 33 can be provided also within the female connector 14, or within the nipple 22, 24 of the capsule 20.
  • the accepting lip of the female connector 14 comprises a surface and a periphery complimentary to the male connector 12 such that when the female connector 14 and the male connector 12 are mated, the accepting lip of the female connector 14 surrounds the male connector 12 in a water-tight manner.
  • This can be achieved as the material of said parts are elastomeric material so that the accepting lips for instance can wrap tightly around the other parts.
  • several valves 33 can be provided to the capsule 20.
  • the valve 33 can be provided to the male connector 12 and/or female connector 14 and/or nipple 22, 24 of the capsule 20.
  • the valve 33 can be for instance flanged duckbill valves.
  • Flanged duckbill valves are unique, one-piece, elastomeric components that act as backflow prevention devices or one-way valves or check valves. They have elastomeric lips 35 in the shape of a duckbill which prevent backflow and allow forward flow.
  • the main advantage of duckbill valves over other types of one-way valves is that duckbill valves are self-contained i.e., the critical sealing function is an integral part of the one-piece elastomeric component as opposed to valves where a sealing element has to engage with a smooth seat surface to form a seal. Therefore, duckbill valves are easily incorporated and assembled into the capsule 20 without the hassle or problems associated with the surface finish quality of mating seats and/or complex assembly processes.
  • valve 33 when the valve 33 is provided to the capsule 20 especially to the male connector 12, it has other advantages such as position independent, low opening pressure-immediate free flow, virtually no internal volume and dead space, corrosion resistant, wear resistant and cost effective.
  • the capsule 20 and/or the valve 33 according to the present invention can be provided in various elastomeric material such as medical and food-grade silicone or hydrocarbon-resistant fluoro-silicone rubber in order to handle a broad range of media and temperatures.
  • Figures 4A and 4B show another embodiment of the invention, wherein a secondary protruding element is provided to the male connector 12 and/or the female connector 14.
  • a nipple 22, 24 is provided to the top of the male connector 12 and the female connector 14, respectively, wherein a secondary sealed opening 25 can be seen provided on the surface of the nipple.
  • the characteristics and the features of the secondary sealed opening 25 can be identical to the primary sealed opening 15.
  • a two-step rupturing of the sealed openings 15, 25 are provided to the capsule.
  • the two capsules 20 When a user connects the male connector 12 of a capsule 20 with a female connector 14 or another capsule 20, the two capsules 20 are connected while the primary sealed openings 15 are being ruptured while the secondary sealed openings 25 remained intact.
  • a typical "click" sound may be heard when the two capsules 20 are connected to each other in order to notify the user that the connection has been established.
  • This can be realised by providing a pin or little protruding-like element on the male connector 12 and grooves on the female connector 14.
  • a plurality of capsules 20 can be connected in the similar manner, as seen in the Figure 4B .
  • the secondary sealed openings 25 can then be ruptured to established fluid communication when the user decides to operate the battery of capsules 20 by pressing the capsules for example through the two longitudinal ends. As the secondary sealed openings 25 are ruptured only after the primary sealed openings 15, a fluid communication of the liquid substance between the capsules 20 is therefore established. This allows the user to enjoy the content of the capsule with an increased volume without needing to replace the empty capsule frequently. Alternatively, the user has always some additional capsules 20 available and may decide whenever to furnish the vaping device with the additional liquid substance. This provides the user with a higher degree of freedom and flexibility.
