The present invention relates generally to electronic smoking devices and in particular to a tray for at least a portion of an electronic smoking device.
An electronic smoking device, such as an electronic cigarette (e-cigarette), typically has a housing accommodating an electric power source (e.g. a single use or rechargeable battery, electrical plug, or other power source), and an electrically operable atomizer. The atomizer vaporizes or atomizes liquid supplied from a reservoir and provides vaporized or atomized liquid as an aerosol. Control electronics control the activation of the atomizer. In some electronic cigarettes, an airflow sensor is provided within the electronic smoking device, which detects a user puffing on the device (e.g., by sensing an under-pressure or an air flow pattern through the device). The airflow sensor indicates or signals the puff to the control electronics to power up the device and generate vapor. In other e-cigarettes, a switch is used to power up the e-cigarette to generate a puff of vapor.
Since portions used in electronic smoking devices such as a liquid reservoir are potentially harmful if used inappropriately, e.g. by children, said portions of electronic smoking devices need to be contained in a child-safe manner.
In accordance with one aspect of the present invention, a tray is provided for containing at least a portion of an electronic smoking device in a child-safe manner.
The tray comprises at least one cavity for containing the portion. The tray is configured to be reversibly deformed from a default form (also referred to as undeformed shape) into a deformed form (also referred to as deformed shape) by finger interaction of at least two separate fingers of a user with interaction elements of the tray having a distance to each other of at least 90% of the average distance between thumb tip and index finger tip or a middle finger tip of an adult. The tray is configured to return to the default form once the finger interaction is terminated. The default form provides the at least one cavity for containing the portion in an inaccessible manner and the deformed form is required for accessing the portion.
The characteristics, features and advantages of this invention and the manner in which they are obtained as described above will become more apparent and be more clearly understood in connection with the following description of exemplary embodiments, which are explained with reference to the accompanying drawings.
In the drawings, same element numbers indicate same elements in each of the views:
Throughout the following, an electronic smoking device will be exemplarily described with reference to an e-cigarette. As is shown in
The battery portion 12 and atomizer/liquid reservoir portion 14 are typically made of metal, e.g. steel or aluminum, or of hardwearing plastic and act together with the end cap 16 to provide a housing to contain the components of the e-cigarette 10. The battery portion 12 and an atomizer/liquid reservoir portion 14 may be configured to fit together by a friction push fit, a snap fit, or a bayonet attachment, magnetic fit, or screw threads. The end cap 16 is provided at the front end of the battery portion 12. The end cap 16 may be made from translucent plastic or other translucent material to allow a light-emitting diode (LED) 20 positioned near the end cap to emit light through the end cap. The end cap can be made of metal or other materials that do not allow light to pass.
An air inlet may be provided in the end cap, at the edge of the inlet next to the cylindrical hollow tube, anywhere along the length of the cylindrical hollow tube, or at the connection of the battery portion 12 and the atomizer/liquid reservoir portion 14.
A battery 18, an LED 20, control electronics 22 and optionally an airflow sensor 24 are provided within the cylindrical hollow tube battery portion 12. The battery 18 is electrically connected to the control electronics 22, which are electrically connected to the LED 20 and the airflow sensor 24. In this example the LED 20 is at the front end of the battery portion 12, adjacent to the end cap 16 and the control electronics 22 and airflow sensor 24 are provided in the central cavity at the other end of the battery 18 adjacent the atomizer/liquid reservoir portion 14.
The airflow sensor 24 acts as a puff detector, detecting a user puffing or sucking on the atomizer/liquid reservoir portion 14 of the e-cigarette 10. The airflow sensor 24 can be any suitable sensor for detecting changes in airflow or air pressure, such as a microphone switch including a deformable membrane which is caused to move by variations in air pressure. Alternatively the sensor may be a Hall element or an electro-mechanical sensor.
The control electronics 22 are also connected to an atomizer 26. In the example shown, the atomizer 26 includes a heating coil 28 which is wrapped around a wick 30 extending across a central passage 32 of the atomizer/liquid reservoir portion 14. The coil 28 may be positioned anywhere in the atomizer 26 and may be transverse or parallel to the liquid reservoir 34. The wick 30 and heating coil 28 do not completely block the central passage 32. Rather an air gap is provided on either side of the heating coil 28 enabling air to flow past the heating coil 28 and the wick 30. The atomizer may alternatively use other forms of heating elements, such as ceramic heaters, or fiber or mesh material heaters. Nonresistance heating elements such as sonic, piezo and jet spray may also be used in the atomizer in place of the heating coil.
The central passage 32 is surrounded by a cylindrical liquid reservoir 34 with the ends of the wick 30 abutting or extending into the liquid reservoir 34. The wick 30 may be a porous material such as a bundle of fiberglass fibers, with liquid in the liquid reservoir 34 drawn by capillary action from the ends of the wick 30 towards the central portion of the wick 30 encircled by the heating coil 28.
The liquid reservoir 34 may alternatively include wadding soaked in liquid which encircles the central passage 32 with the ends of the wick 30 abutting the wadding. In other embodiments the liquid reservoir 34 may comprise a toroidal cavity arranged to be filled with liquid and with the ends of the wick 30 extending into the toroidal cavity.
An air inhalation port 36 is provided at the back end of the atomizer/liquid reservoir portion 14 remote from the end cap 16. The inhalation port 36 may be formed from the cylindrical hollow tube atomizer/liquid reservoir portion 14 or maybe formed in an end cap.
In use, a user sucks on the e-cigarette 10. This causes air to be drawn into the e-cigarette 10 via one or more air inlets, such as air inlets 38, and to be drawn through the central passage 32 towards the air inhalation port 36. The change in air pressure which arises is detected by the airflow sensor 24, which generates an electrical signal that is passed to the control electronics 22. In response to the signal, the control electronics 22 activate the heating coil 28, which causes liquid present in the wick 30 to be vaporized creating an aerosol (which may comprise gaseous and liquid components) within the central passage 32. As the user continues to suck on the e-cigarette 10, this aerosol is drawn through the central passage 32 and inhaled by the user. At the same time the control electronics 22 also activate the LED 20 causing the LED 20 to light up which is visible via the translucent end cap 16 mimicking the appearance of a glowing ember at the end of a conventional cigarette. As liquid present in the wick 30 is converted into an aerosol more liquid is drawn into the wick 30 from the liquid reservoir 34 by capillary action and thus is available to be converted into an aerosol through subsequent activation of the heating coil 28.
Some e-cigarettes are intended to be disposable and the electric power in the battery 18 is intended to be sufficient to vaporize the liquid contained within the liquid reservoir 34, after which the e-cigarette 10 is thrown away. In other embodiments the battery 18 is rechargeable and the liquid reservoir 34 is refillable. In the cases where the liquid reservoir 34 is a toroidal cavity, this may be achieved by refilling the liquid reservoir 34 via a refill port. In other embodiments the atomizer/liquid reservoir portion 14 of the e-cigarette 10 is detachable from the battery portion 12 and a new atomizer/liquid reservoir portion 14 can be fitted with a new liquid reservoir 34 thereby replenishing the supply of liquid. In some cases, replacing the liquid reservoir 34 may involve replacement of the heating coil 28 and the wick 30 along with the replacement of the liquid reservoir 34. A replaceable unit comprising the atomizer 26 and the liquid reservoir 34 is called a cartomizer.
The new liquid reservoir 34 may be in the form of a cartridge having a central passage 32 through which a user inhales aerosol. In other embodiments, aerosol may flow around the exterior of the cartridge 32 to an air inhalation port 36.
Of course, in addition to the above description of the structure and function of a typical e-cigarette 10, variations also exist. For example, the LED 20 may be omitted. The airflow sensor 24 may be placed adjacent the end cap 16 rather than in the middle of the e-cigarette. The airflow sensor 24 may be replaced with a switch which enables a user to activate the e-cigarette manually rather than in response to the detection of a change in air flow or air pressure.
Different types of atomizers may be used. Thus, for example, the atomizer may have a heating coil in a cavity in the interior of a porous body soaked in liquid. In this design, aerosol is generated by evaporating the liquid within the porous body either by activation of the coil heating the porous body or alternatively by the heated air passing over or through the porous body. Alternatively the atomizer may use a piezoelectric atomizer to create an aerosol either in combination or in the absence of a heater.
Essentially perpendicular to its upper surface, the tray 100 comprises two lateral surfaces being parallel to each other having a relatively longer distance to each other and two lateral surfaces 102, 103 being parallel to each other having a relatively shorter distance to each. These lateral surfaces 102, 103 have a width (distance between each other) perpendicular to the other lateral surfaces of at least 4.5 cm or more. According to embodiments of the present invention, said width (distance) between the lateral surfaces 102, 103 is greater than 5.0 cm, more preferably greater than 5.5 cm, more preferably greater than 6.0 cm, more preferably greater than 6.5 cm, more preferably greater than 7.0 cm, more preferably greater than 7.5 cm, more preferably greater than 8.0 cm and more preferably greater than 8.5 cm. In this sense, alternatively expressed, the shorter lateral surfaces have a width perpendicular to the longer lateral surfaces 102, 103 of at least 65% of the average distance between index finger tip or middle finger tip and thumb tip of an adult, more preferably of at least 65%, more preferably of at least 70%, more preferably of at least 75%, more preferably of at least 80%, more preferably of at least 85% and more preferably of at least 90%.
Accordingly, the separate lateral surfaces 102, 103 are spaced apart such that small childrens' hands are not able to press the two areas (lateral surfaces 102, 103) with the fingers of one hand at the same time. Even if a non-authorized user would press the lateral surfaces 102, 103 with different hands, the user would not be able to removed an electronic cigarette (or a part thereof) from the tray 100 because the unlocking mechanism (activated under sufficient pressure to the separate lateral surfaces 102, 103) is configured such that the electronic cigarette (or a part thereof) is only unlocked but not automatically ejected from the cavity 101 and accordingly another hand (not pressing the lateral surfaces 102, 103) is required to remove the unlocked electronic cigarette (or a part thereof) from the cavity 101 before releasing the pressure from the at least two interaction elements (lateral surfaces 102, 103).
The tray 100 comprises a (preferably deeply drawn) cavity 101 in which an exemplary elongated e-cigarette 10 is contained (or accommodated) with two ends extending parallel to the lateral surfaces 102, 103. The tray 100 comprises an outer portion 110 which surrounds two inner portions 120. There is a (deeply drawn) groove 140 located between the outer portion 110 and the inner portions 120. Each of the inner portions 120 surrounds one of the two ends in a manner that no finger can be put between the respective inner portion 120 and the respective end. Hence, the ends of the e-cigarette 10 cannot be accessed either by a child or by an adult without pressing the two interaction elements (lateral surfaces 102, 103).
In a remaining middle section of the e-cigarette 10, parts 111 of the outer portion 110 of the tray 100 surround the e-cigarette 10 directly without any of the inner portions 120 in between. The parts 111 surround the middle section in a manner that no finger can be put between the middle section and the outer portion 110. Hence, also the remaining middle portion of the e-cigarette 10 cannot be accessed either by a child or by an adult without pressing the two interaction elements (lateral surfaces 102, 103).
Thus, in a default form (undeformed shape), the tray 100 accommodates the e-cigarette 10 inaccessible by fingers of a user.
The tray 100 may be a plastic container, for example a thermoformed plastic container. In another exemplary and non-limiting embodiment the tray 100 is injection molded.
The outer portion 110 has (deeply drawn) indentations 130 extending from the lateral surfaces 102, 103 towards the middle section only separated therefrom by parts 110.
According to embodiments of the present invention, said predetermined pressure threshold may be such that it corresponds to 30%, more preferably of at least 35%, more preferably of at least 40%, more preferably of at least 45%, more preferably of at least 50%, more preferably of at least 55%, more preferably of at least 60%, more preferably of at least 65%, more preferably of at least 70%, more preferably of at least 75%, more preferably of at least 80%, more preferably of at least 85% and more preferably of at least 90% of the pressure an adult can apply in average with tips of the index finger or of the middle finger and of the thumb. In this sense, alternatively expressed, a force applied to tray 100 via the at least two interaction elements (lateral surfaces 102, 103) may be more than 0.1 N, more preferably more than 0.2 N, more preferably more than 0.4 N, more preferably more than 0.8 N, more preferably more than 1.6 N, more preferably more than 3.2 N and more preferably more than 5 N.
Simultaneous pressure on the lateral surfaces 102, 103 (or alternatively force on the tray 100 applied via lateral surfaces 102, 103) causes at least one of the inner portions 120 to be lifted with respect to the outer portion 110. Thereby, the e-cigarette 10 is lifted, at least partly, too. Particularly, the middle section of the e-cigarette 10 is lifted (but not completely ejected) at least partly above the part 111 of the outer portion. Thereby the middle section becomes accessible, i.e. it can be taken out with the fingers. However, when the e-cigarette 10 is not taken out and the pressure (or force) is removed, the e-cigarette 10 becomes inaccessible again, i.e. the e-cigarette 10 is locked again.
Thus, an adult capable of pressing the interaction elements (lateral surfaces 102, 103) with a single hand sufficiently strong can take out the e-cigarette with the fingers of the other hand while keeping the interaction elements (lateral surfaces 102, 103) pressed. In contrast, a child or teenager needs both hands for applying sufficient pressure (or force) and therefore cannot take out the e-cigarette 10.
The tray 200 depicted in
The cavities 201 are provided in a rotatable portion 220 which is rotatable around a normal of the top surface of the tray 200. The cavities 201 extend radially having openings at a cylindrical surface 214 of the rotating device 220. In the default form (undeformed state), the openings of the cavities 201 are at least partly covered by the outer portion 210. The tray 200 further comprises an outer portion 210. In a default form of the tray 200, the rotatable portion 220 is surrounded by the outer portion 210 such that the rotatable portion 220 is inaccessible for being rotated by hand. Alternatively or additionally, the rotatable portion 220 is blocked by the outer portion 210 from being rotated when the tray 200 is in its default form. Alternatively or additionally, the openings of the cavities 201 are at least partly covered by the outer portion 210 in the default form.
The tray 200 comprises, e.g. as part of the outer portion, lateral surfaces 202, 203 functioning as interaction elements and extending essentially perpendicular to the top surface. The separate lateral surfaces 202, 203 have a distance from each other as specified in connection with
Simultaneous pressure on the lateral surfaces 202, 303 causes the rotatable portion 220 to be lifted with respect to the outer portion 210 such that it becomes accessible for being rotated by hand and/or the blocking of the rotatable portion 220 by the outer portion to be released such that the rotatable portion 220 can be rotated. However, at least all but one opening of the cavities 201 remains at least partly covered by the outer portion 210 in the deformed state, too. Particularly all openings of the cavities 201 are partly covered by the lateral surface 205 even in the deformed state as long as the rotatable portion has not been rotated.
Therefore an adult (having a sufficiently large hand) capable of pressing said lateral surfaces with a single hand sufficiently strong can lift and/or release the rotatable portion 220 with the fingers of the one hand and use the other hand for simultaneously rotating the rotatable portion 220 in order to move the opening of one of the cavities to a position where its content can be accessed. But a child or teenager (having an insufficiently small hand) needs both hands for applying the pressure or for applying sufficient pressure and then cannot rotate the rotatable portion 220.
The deformed state can be achieved by pressure (or force) on the lateral surfaces 202, 203 of the tray 200. Hence, for achieving deformation with a single hand, the hand span must be large enough as specified above. Otherwise, two hands are required for applying sufficient pressure (or force) on the lateral surfaces 202, 103 of the tray 200 such that the tray 200 becomes deformed. Once pressure is released, the tray 200 immediately returns back into the default state, e.g. the tray 200 snaps back into the default state. In an embodiment, deforming requires a pressure exceeding a predetermined pressure threshold specified above or a predetermined force specified above.
Simultaneous pressure on the lateral surfaces 202, 203 causes the rotatable portion 220 to be lifted with respect to the outer portion 210 such that the cylindrical surface 222 becomes visible. Though lifted, all of the openings 221 of the cavities 201 are still partly covered by the lateral surface 205 of outer portion 210. By means of appropriate rotation, the opening of one the cavities may be aligned with an indentation 211. The indentation 211 is formed such that it allows access to content of a cavity having its opening aligned with the indentation 211.
The further lateral surface 205 has an indentation 211 arranged corresponding to the openings 221 such that, by rotating the rotatable portion 220, one of the openings 221 can be aligned with the indentation 211 and the e-cigarette's portion contained in the respective cavity 201 becomes accessible. According to embodiments of the present invention, the objects (electronic smoking device or a part of the electronic smoking device) may be fixed in the cavities 201 such that they can only be taken out with another device (e.g. battery 18).
Since rotation is only possible while simultaneous pressure is applied, both hands are required simultaneously for taking out the functional components of an electronic smoking device such as a cartomizer, a liquid reservoir, an atomizer/liquid reservoir portion or a mouthpiece portion. Therefore, only an adult can do so but a child or teenager cannot apply sufficient pressure with a single hand therefore not having a free hand for doing the rotation even if capable of applying sufficient simultaneous pressure with both hands.
The tray 200 may be a plastic container, for instance a thermoformed plastic container. In another exemplary and non-limiting embodiment the tray 200 is injection molded.
The tray 300 depicted in
The tray 300 surrounds the portions in a manner that no finger can be put between the portions and the tray 300 when the tray is in the undeformed state. Hence, also portions of the e-cigarette 10 contained or accommodated in the cavities 301 of the tray 300 cannot be accessed either by a child or by an adult when the tray 300 is in the undeformed state. Lid portions of the tray 300 cover openings of the cavities 301 in the undeformed state.
In the deformed state, the lid portions are flapped away from the openings such that portions of an electronic cigarette contained in the options become accessible. In some embodiments, the access is restricted to use of a further portion of the electronic smoking device. That is, in some embodiments the portions still cannot be taken out by hand even if the tray is in the deformed state. Instead, the further portion may be fit to the portion in the cavity, for example by a friction push fit, a snap fit, or a bayonet attachment, magnetic fit, or screw threads.
The tray 300 may be a plastic container, for instance a thermoformed plastic container. In another exemplary and non-limiting embodiment the tray 300 is injection molded.
In an exemplary embodiment of a first aspect of the invention there is a tray for containing at least a portion of an electronic smoking device in a child-safe manner. The tray comprises at least one cavity for containing the portion.
The tray is configured to be reversibly deformed from a default form into a deformed form by finger interaction with interaction elements of the tray having a distance to each other of at least 90% of the average distance between thumb tip and index finger tip or a middle finger tip of an adult.
The tray is configured to return to the default form once the finger interaction is terminated. The default form provides the at least one cavity for containing the portion in an inaccessible manner and the deformed form being required for accessing the portion.
The interaction elements may be located on opposite surfaces of the tray.
The finger interaction may comprise applying pressure on the interaction elements.
The pressure required for deforming the tray into the deformed form may be at least 90% of the pressure which an average adult can apply on the interaction elements using the thumb tip and the index finger tip or the middle finger tip.
By deforming the tray, an opening in the tray of the cavity may be opened to a width allowing the portion to be accessed and taken out.
By deforming the tray, the portion may be further moved, at least partly, through the opening.
The tray may comprise a rotatable portion providing the cavity. In the default form, the rotatable portion may be inaccessible for rotation by hand and/or may be blocked from being rotated. In the deformed form, the rotatable portion may be accessible for rotation. Rotation may be required of the rotatable portion in the deformed form for accessing the portion.
Rotation may be required of the rotatable portion in the deformed form a starting point to a predetermined point for accessing the portion.
Before the finger interaction is terminated for the tray returning into the default form, counter-rotation in the deformed form to the starting point may be required.
The cavity may be configured for containing an electronic smoking device.
The portion may be a mouthpiece portion, a liquid reservoir portion, a cartomizer or an atomizer/liquid reservoir portion.
The tray may comprise multiple cavities.
An advantage of certain embodiments may be that child-safe containment of electronic smoking devices and/or associated portions can be achieved.
While this invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the scope of the appended claims.
