The present invention relates to a container, in particular a container for storing liquid and particularly, but not exclusively to a container configured to be refilled from a dispenser.
A smoking-substitute device is an electronic device that permits the user to simulate the act of smoking by producing an aerosol mist or vapour that is drawn into the lungs through the mouth and then exhaled. The inhaled aerosol mist or vapour typically bears nicotine and/or other flavourings without the odour and health risks associated with traditional smoking and tobacco products. In use, the user experiences a similar satisfaction and physical sensation to those experienced from a traditional smoking or tobacco product, and exhales an aerosol mist or vapour of similar appearance to the smoke exhaled when using such traditional smoking or tobacco products.
A smoking-substitute device generally uses heat and/or ultrasonic agitation to vaporize a solution comprising nicotine and/or other flavouring, propylene glycol and/or glycerine-based base into an aerosol mist of vapour for inhalation. A person of ordinary skill in the art will appreciate that the term “smoking-substitute device” as used herein includes, but is not limited to, electronic nicotine delivery systems (ENDS), electronic cigarettes, e-cigarettes, e-cigs, vaping cigarettes, pipes, cigars, cigarillos, vaporizers and devices of a similar nature that function to produce an aerosol mist or vapour that is inhaled by a user. Some electronic cigarettes are disposable; others are reusable, with replaceable and refillable parts.
Smoking-substitute devices typically resemble a traditional cigarette and are cylindrical in form with a mouthpiece at one end through which the user can draw the aerosol mist or vapour for inhalation, These devices usually share several common components: a power source such as a battery, a reservoir for holding the liquid to be vaporized, a vaporization component for atomizing and/or vaporizing the liquid and to thereby produce an aerosol mist and/or vapour, and control circuitry operable to actuate the vaporization component responsive to an actuation signal from a switch operative by a user or configured to detect when the user draws air through the mouthpiece by sucking or inhaling.
The reservoir may be either a replaceable or refillable container that is coupled to, or located in, the main body of the smoking-substitute device and that is typically made of a resilient plastic material such as high-density polypropylene. The reservoir generally contains a wicking material in which the liquid is stored but may just be a storage space without any wicking material. Once the replaceable or refillable reservoir is emptied it must either be replaced or refilled.
Replaceable type reservoirs are typically provided in the form of a pre-filled cartridge that can be. securely and removably engaged to, or within, the cylindrical main body of the smoking-substitute device. These reservoir and vaporization elements may also be integrated into a single component commonly known as a “cartomizer” that may be disposable or refillable. Additionally, replaceable type reservoirs may also be integrally formed with the mouthpiece.
In order to fit a replaceable type reservoir to, or within, the main body of a smoking- substitute device, features of the main body are configured to engage with complementary features formed on a portion of the reservoir to securely and removably couple the reservoir to the main body of the smoking substitute device and to thereby prevent the accidental or unintended separation of the reservoir from the smoking-substitute device. These complementary features typically secure the reservoir to the main body of the smoking- substitute device with a close or interference fit and the fitting step causes a portion of the reservoir to pierce the reservoir to permit liquid to be dispensed.
Alternatively, and most commonly, users utilise refillable type reservoirs. Typically, the refillable reservoir of the smoking-substitute device is refilled by dispensing liquid from a dispenser that commonly resembles the small dropper bottles used for dispensing eye drops. Refill dispensers are preferred principally for their low cost,
The ingredients of the liquid for producing the aerosol mist or vapour in smoking-substitute devices vary widely, but typically include water and flavourings in a propylene glycol and/or glycerol base. Nicotine may also be included in solutions intended to fulfil a nicotine replacement role, without the harmful products associated with tobacco smoke.
A person of ordinary skill in the art will appreciate that the term “liquid” as used herein, may include, but is not limited to, any liquids, gels, powders and gases together with liquids comprising mixtures of liquids, gels, powders and gases that are capable of being atomized or vapourized whether or not using heat and/or ultrasonics. Additionally, the term “liquid” as used herein may also include, but is not limited to, powders capable of being entrained in a fluid flow, for example an airflow.
Both pre-filled reservoirs of the replaceable type and refillable type reservoirs can be prone to leakage of liquid contents via a conduit by which these reservoirs are filled. It will be appreciated that this is undesirable, given the potential ingredients that these reservoirs can hold.
Aspects and embodiments of the invention were devised with the foregoing in mind.
According to an aspect of the present invention, there is provided a container operative with a dispenser comprising a dispense conduit, the container comprising:
a storage cavity for storing contents dispensed to the container from the dispenser;
an interface formation configured to receive the dispense conduit of the dispenser to open a conduit between the storage cavity and a reservoir of the dispenser to permit transfer of reservoir contents from the reservoir of the dispenser to the storage cavity; and wherein the interface formation comprises a rupturable, self-sealing membrane.
A rupturable, self-sealing membrane may be particularly suited to use with a dispenser having a sharp dispense conduit. This may obviate the need to provide a cap over a ruptured membrane to avoid leakage from the container due to the ruptured membrane “self-sealing” when a filling operation is complete. The rupturable, self-sealing membrane may comprise a suitable self-sealing material, such as, for example, silicone. In particular, the membrane may be made entirely of silicone.
The interface formation of the container comprises an arrangement that is complementary to the dispense conduit such that contents can he delivered to the storage cavity of the container from the dispenser. This may reduce the likelihood of spillage and/or contamination of the reservoir contents during transfer from the dispense conduit to the container to be filled. In a particular embodiment, the container is penetrable by the dispense conduit of the dispenser to deliver reservoir contents into the container. Penetration into the container to be filled further reduces the likelihood of spillage and contamination of the reservoir contents as they are transferred to the container. Penetration of the dispense conduit into the container provides for delivery of the reservoir contents from the dispense conduit into the container storage cavity thereby avoiding spillage of the reservoir contents during filling.
Suitably, the interface formation is disposed in an interface section of the container configured to fit to the open ended tube in order for the dispense conduit to engage with the interface formation.
The interface section is configured to be insertable into an open ended tube of a dispenser and in particular is configured to form a transition fit with the open ended tube. A transition fit assists in controllably guiding the interface section into the open ended tube such that it may interface with the dispense conduit.
In one or more embodiments, the interface section comprises an abutment surface configured to contact a complementary abutment surface of the dispenser. Thus, the container may be contacted by a user in order to actuate the dispenser thereby decreasing the likelihood of a user coming into contact with the dispense conduit due to the intermediary provided by the interface section.
The interface section may comprise formations complementary to formations in the dispenser for providing positive engagement therewith in order to inhibit inadvertent separation of the container from the dispenser during operation.
The interface section typically comprises a hollow member at one end of which is the interface formation such that in use a dispense conduit can enter into the hollow member to reach the interface formation.
Suitably, the container may be configured as a container for a nicotine vapour precursor liquid for a smoking substitute device, for example configured as a cartomiser. In embodiments in which the container is configured for a smoking substitute device such as a cartomiser, it is particularly convenient for the interface section to be configured as a mouthpiece. However, the interface section may be configured as a mouthpiece for use with containers other than for smoking substitute devices.
One or more embodiments in accordance with aspects of the present invention will be described, by way of example only, and with reference to the following drawings in which:
The dispenser 10 comprises an elongate, hollow, cylindrical housing 12, which is closed at a first end and open at a second, opposite end, and a cap 14 for closing off the second, open end.
When the cap 14 is removed, an end of a container to be filled can be inserted into the open ended tube 18 of the dispenser 10 via the aperture 16.
The pump device 20 comprises an intake conduit 22 in fluid communication with a pump arrangement 24. Pump arrangement 24 is configured for location at, adjacent, or about a first end of the reservoir portion 12a and is in fluid communication with a dispense conduit 26.
Intake conduit 22 (also known as a “dip tube”) extends from the pump arrangement 24 so that, when the pump device 20 is located within housing 12, the intake conduit 22 extends to a second end of the reservoir portion 12a distal the first end. The intake conduit 22 is configured for communicating contents in the reservoir portion 12a from the second end thereof to pump arrangement 24.
The intake conduit 22 comprises a notch across its walls (not shown in
Dispense conduit 26, such as, for example, a dispense tip, extends from the pump arrangement 24 and comprises a dispense aperture (not shown) at an end thereof. The dispense aperture is in fluid communication with the pump arrangement 24.
When pump device 20 is located within housing 12, the open ended tube (not shown in
The pump arrangement 24 comprises valve seat element 2400, a hollow cylindrical member 2410, an operating rod 2440, a body portion 2450 and a pump actuator 2460. The pump actuator 2460 is in fluid communication with body portion 2450 by way of operating rod 2440, and valve seat element 2400 is in fluid communication with body portion 2450 by way of hollow cylindrical member 2410. The valve seat element 2400 is in fluid communication with intake conduit 22 and the pump actuator 2460 is in fluid communication with the dispense conduit 26. Thus, a fluid passage is provided through the pump arrangement to provide a fluid passage from a remote end of the intake conduit 22, via the pump arrangement, to a remote end of the dispense conduit 26.
Referring now to
Pump device 20 comprises intake conduit 22 coupled to valve seat element 2400, which is coupled to hollow cylindrical member 2410. The pump device further comprises an upper valve 2420, a piston member 2430, operating rod 2440, a body portion 2450, and a pump actuator 2460. Cylindrical member 2410 has mounted thereunder the valve seat element 2400 and the intake conduit 22 to be placed in reservoir portion 12a of dispenser 10 and includes a reservoir chamber 2412, a top engaging portion 2414, an annular flange 2416 positioning thereon body portion 2420 to be seated against seat portion 12c, which is a flange disposed around the interior of reservoir portion 12a at said first end thereof. A lower portion of the cylindrical member 2410 is configured for coupling to said valve seat clement 2400 in which is located a ball 2418
Upper valve 2420 includes a body portion 2422 having a bottom positioning ring 2422c and two top concentric annular grooves 2422a, 2422b of triangular cross-section, an upper engaging medium 2424 having three upward rectangular wings 2424a respectively having three top inner triangular indentations 2424b to facilitate passing the liquid from three passages 2424c defined by wings 2424a to operating rod 2440, and a downward engaging rod 2426 having a bottom end 2426a split into three fingers 2426b. A compression spring 2428 is positioned in cylindrical member 2410 and mounted between positioning ring 2422c and valve seat element 2400.
Piston 2430 includes a through hole 2432, two concentric bottom annular teeth 2434, 2436 respectively engageable with grooves 2422a, 2422b, a top inner annular indentation 2438 and a top outer annular indentation 2439 and is sleeved in cylindrical member 2410 to be movable along the inner wall thereof.
Operating rod 2440 is hollow and includes a top end 2441, a bottom end having a bottom annular projection 2442 engageable in inner indentation 2438 when operating rod 2440 is pressed downward, and a through hole which includes a shoulder surface 2444 defining thereabove an upper hole 2446 and thereunder a lower hole 2448 receiving therein the upper portion of upper engaging medium 2424 bearing against shoulder surface 2444.

In operation, as shown in
The assembled dispenser 10 can be seen in cross section view in both
As can be seen in
The container 28 can be filled with liquid contained in the reservoir portion 12a of housing 12 by exerting a force (in the direction denoted by arrow X in the figure) on the exposed end of the container 28 to urge container 28 from a rest position into the dispenser 10. This action causes an end of the container 28 within the dispenser to abut an end of the pump arrangement (not shown in
Upon release of the depressing force, the compression spring within the pump arrangement urges the container 28 from the fully depressed position towards the rest position (i.e, in the direction denoted by arrow Y in the figure).
The container 28 can be moved through a number of depression and release cycles in order to fill the container. However, the pump device 20 optionally may be such that the container can be filled by way of a single depression and release cycle. The pump arrangement dimensions may be such that each depression and release cycle delivers a measured dose of contents such as a medicament in order to avoid inadvertent over medication by a user.
In a further illustrative example of subject matter related to the present invention, as illustrated in
The plug 34 comprises a disc-shaped element, which includes an annular recess 36 in a top surface thereof. The annular recess 36 surrounds a shaft 38 in which is provided an engagement formation (e.g. a helically threaded bore 40 as illustrated in
The plug 34 provides an additional feature (i.e. additional to cap 14) for inhibiting inadvertent contact with the dispense conduit 26.
In the illustrated example of
An example of a procedure for removal of the plug 34 from the open ended tube 18 is illustrated in
Container (cartomiser) 28 comprises, at a non-mouthpiece end thereof, an engagement formation, which conventionally is for securely and removably coupling the container (cartomiser) 28 to a complementary engagement formation of a battery unit of an e-cigarette device. In the illustrated example, engagement formation comprises a helically threaded shaft 42.
To remove the plug 34 from the open ended tube 18, container (cartomiser) 28 is located so that an end of helically threaded shaft 42 thereof is proximal helically threaded bore 40 of plug 34 such that a thread at the end of the helically threaded shaft 42 begins to engage the thread at the mouth of the helically thread bore 40. Relative rotation of the container (cartomiser) 28 with respect to the dispenser 10 (and thus to the plug 34) causes the helically threaded shaft 42 to move into the helically thread bore 40. Continued relative rotation causes the container (cartomiser) 28 to be tightened onto the plug 34 and thus securely couple the container (cartomiser) 28 to the plug 34.
With the container (cartomiser) 28 securely coupled to the plug 34 (see
The plug 34 is retained by the container (cartomiser) 28, which may avoid the plug 34 being misplaced when it has been removed from the dispenser 10.
An example of a procedure for filling, or refilling a container (from an initial state in which the dispenser is closed by both cap 14 and plug 34, to insertion of the container and “pumping” the container relative to the housing) is illustrated in
Removal of cap 14 (see
Container (cartomiser) 28 is located so that an end of helically threaded shaft 42 thereof is proximal helically threaded bore 40 of plug 34 such that a thread at the end of the helically threaded shaft 42 begins to engage the thread at the mouth of the helically thread bore 40. That is, by moving the container (cartomiser) 28 toward the open end of the dispenser 10 in the direction indicated by arrow C of
Rotation of the container (cartomiser) 28 relative to the dispenser 10 (and thus to the plug 34) causes the helically threaded shaft 42 to move into the helically thread bore 40 (see arrow D of
With the container (cartomiser) 28 securely coupled to the plug 34, the plug 34 can be removed from the open ended tube 18 by exerting a pulling force (see arrow E of
Rotation of the container (cartomiser) 28 through 180° (see arrow F of
As described above in relation to
Upon release of the depressing force, the compression spring within the pump arrangement urges the container (cartomiser) 28 from the fully depressed position towards the rest position.
The container (cartomiser) 28 can be moved through a number of depression and release cycles (indicated by arrow H in
The cartorniser 28 comprises a mouthpiece end 44 having a conduit 46 that extends into the body of the cartomiser 28. This conduit 46 can receive the dispense conduit 26 therein when the cartomiser 28 is located in the dispenser (during a filling process). The cartamiser 28 further comprises a reservoir 48 for holding a liquid and a heating arrangement 50 in fluid communication with liquid in the reservoir 48.
During operation of an e-cigarette device comprising the cartomiser 28, the heating arrangement 50 vaporises liquid stored in the reservoir 48, and vapour products are dispensed from the cartomiser 28 via conduit 46 (i.e. via a fluid communication path (not shown) that lead from the reservoir to the conduit 46).
The cartomiser 28 further comprises a rupturable, self-sealing membrane 52 configured to sealably close a liquid communication path between the conduit 46 and the reservoir 48. The rupturable, self-sealing membrane 52 does not interfere with the fluid communication path between the reservoir 48 and the conduit 46, such that vapour products created during use bypass the rupturable, self-sealing membrane 52 during passage from the reservoir 48 to the conduit 46 via the fluid communication path.
During a filling process of the cartomiser 28 (using the dispenser 10 described above), the dispense conduit 26 of dispenser 10 pierces material of the rupturable, self-sealing membrane 52 to provide a fluid passage from the dispenser 10 to the reservoir 48 of the cartomiser 28.
Optionally, self-sealing material of the membrane 52 may comprise, for example, silicone. This can be pierced by the dispense conduit 26, when the cartomiser 28 is introduced into the dispenser 10, and can self-seal when the cartomiser 28 is removed from the dispenser 10.
Although the container according to one or more embodiments of the present invention is described and illustrated as a container in which a filling conduit thereof is the same as a conduit through which contents are released during use, the container may comprise a separate filling conduct. In such a case, the rupturable, self-sealing membrane will be configured and located to seal the tilling conduit.
