Description

CLAIM FOR PRIORITY

The present application claims the benefit of and priority to U.S. Provisional Application No. 63/394,851, entitled VAPING CARTRIDGE and filed on Aug. 3, 2022, the entire contents of which are herein incorporated by reference.

TECHNICAL FIELD

The present disclosure relates generally to devices using liquid inhalable precursors. More specifically the disclosure relates to cartridges which can be used with vaping devices.

BACKGROUND

Vaping devices, vaporizing devices, and vaping systems may be used for portable vaping. A vaping device may vaporize a pre-vapor formulation, such as an oil, liquid, or fluid that may or may not contain one or more cannabinoids, to form a vapor. The vaping device may include a reservoir that holds the pre-vapor formulation or oil and a heating element that vaporizes the pre-vapor formulation or oil by applying heat to at least a portion of the pre-vapor formulation or oil. Vaping devices are often sold and shipped directly to local oil manufacturers, where they are filled with a pre-vapor formulation or oil, and then capped by the local oil manufacturers.
In use, the vapor produced by heating and vaporizing the oil is inhaled by a user as the user draws on a proximal end of the device. Specifically, produced vapor travels through interior lumens or channels within the device and exits a proximal outlet. If the travel distance of the vapor is sufficiently long, the vapor cools significantly within the interior lumen or channel before exiting the device. While a degree of coolness is desired so that a user is not burned when inhaling the vapor, if the vapor cools too much and/or too quickly, particles within the vapor can deposit on surfaces of the interior lumen or channel. Deposition of vapor particles can build up or aggregate within the interior lumen or channel and clog the interior lumen, leading to breakage or failure of the vaping device. Devices with narrow interior lumens or channels exacerbate this problem, as the vapor particles are moving in a smaller volume and more likely to collide and deposit on surfaces of the interior lumen or channel.

DETAILED DESCRIPTION

The present disclosure relates generally to a system and device for vaping. As used herein, “proximal” refers to a portion of the system or device that is closer to the user's mouth when the vaping device is in use and “distal” refers to a portion of the system or device that is farther from the user's mouth when the vaping device is in use. For example, the systems and methods herein may have a mouthpiece connectable to a proximal end of a tank, and a base connectable to a distal end of a tank. The mouthpiece has a distal end for connection to a tank and a proximal end for a user to draw.
FIGS. 1-2 show a vaping cartridge, generally indicated at 10, with a tank or body 15 and a center post 20, which may extend proximally beyond a proximal end 14 of the tank 15. The tank 15 defines a reservoir 18 (FIG. 2 ) for holding a liquid or oil to be vaporized. A distal end 16 of the tank 15 and/or a distal base 26 of the center post 20 may be connectable to a threaded base 17, which may be for connecting the vaping cartridge 10 to a power source, such as a battery. In some embodiments, the threaded base 17 is connectable to the distal end 16 of the tank 15 and/or the distal base 26 of the center post 20 through one or more projections 19. For example, as illustrated in FIG. 2 , the threaded base 17 may include two projections or pins 19 that mate with or are received by slots 27 in the distal base 26 of the center post 20 (see FIG. 3 ). In some embodiments, the threaded base 17 may include a circular and substantially continuous projection 19 that mates with or is received by a circular and substantially continuous slot 27. In other configurations, the base is in connection with the center post and/or tank through other suitable methods. The connection may be removable or nonremovable.
In some configurations the center post 20 is made of a ceramic material, a material that contains at least some ceramic, or a non-ceramic material can also be used.
As illustrated in FIG. 2 , the tank body 15 has a thickness and includes an inner wall or inner surface 15 a and an outer wall or surface 15 b of the tank body 15. The thickness of the tank body 15 extends from the inner wall or inner surface 15 a to the outer wall or surface 15 b. The thickness of the tank body 15 may be continuous. In some embodiments, the tank body 15 is made from a clear or substantially transparent material, such that a level of a liquid or oil to be vaporized contained within the tank body 15 can be viewed. For example, the tank body 15 may be constructed from an acrylic, plastic, glass, or other appropriate material. In other embodiments, the tank body is formed of non-transparent materials.
As seen most clearly in FIG. 3 , the center post 20 includes a proximal vapor outlet portion 20 a and a distal atomizer housing portion 20 b. The proximal vapor outlet portion 20 a includes a proximal end 21 that extends proximally beyond the proximal end 14 of the tank 15. In some embodiments, an atomizer is housed within the distal atomizer housing portion 20 b of the center post 20. For example, the distal atomizer housing portion 20 b may define a cavity 23 for housing or otherwise receiving the atomizer and/or other elements. As the atomizer heats oil, it is vaporized and when a user inhales through the mouthpiece, the vapor travels proximally through the proximal vapor outlet portion 20 a (i.e., proximally through a lumen 24) to the mouthpiece.
The proximal vapor outlet portion 20 a defines a lumen 24 through which the vapor travels proximally through the cartridge 10. The lumen 24 is in fluid communication with the cavity 23 of the distal atomizer housing portion 20 b, where an atomizer is housed. That is, the lumen is in fluid communication with an atomizer. Specifically, the lumen 24 is in fluid communication with the cavity 23 such that vapor produced by an atomizer travels proximally from the cavity 23 through the lumen 24.
The proximal vapor outlet portion 20 a also includes a transition or shoulder 22, where the center post 20 transitions from the proximal vapor outlet portion 20 a to the distal atomizer housing portion 20 b. The presence of the shoulder 22 allows for varying distances between portions of the center post 20 and the inner surface 15 a of the tank body 15. For example, the distal atomizer housing portion 20 b is wider than the proximal vapor outlet portion 20 a and, thus, will be closer to the inner surface 15 a of the tank body 15 compared to a distance between the proximal vapor outlet portion 20 a and the inner surface 15 a.
The distal atomizer housing portion 20 b defines a cavity 23 and includes a median flange 29, a distal base 26, and one or more voids 25. Defined between the median flange 29 and the distal base 26 is a groove 28 (see FIG. 3 ). The groove 28 may receive a seal or gasket 30 (see FIG. 4 ) to attach or connect the tank body 15 to the center post 20. The seal or gasket 30 may create an air-tight seal between the tank body 15 and the center post 20. In some embodiments, the one or more voids 25 in the distal atomizer housing portion 20 b are located just above the median flange 29. The one or more voids 25 place the cavity 23 in fluid communication with the reservoir 18 defined by the tank body 15. Specifically, the one or more voids 25 allow oil contained within the reservoir 18 to flow through the one or more voids 25 into the cavity 23 and contact the heating element housed within the cavity 23.
In some embodiments, the cavity 23 houses a plurality of operating components for the cartridge 10. For example, referring to FIGS. 4-5 , the cavity 23 may house a heating element (e.g., an atomizer) and a wire 52 for the heating element 50. The wire 52 may be in electrical communication with an electrode 40, such that the electrode 40 can supply electrical current to the wire 52, thereby heating and activating the heating element 50. The electrode 40 may be housed within a cavity of the threaded base 17. The cavity 23 of the distal atomizer housing portion 20 b may also receive one or more insulating sleeves, such as sleeves 60 and 62.
The sleeves 60, 62 may surround or wrap around the heating element 50 and/or the wire 52. The sleeves 60, 62 ensure the heating element 50 and the wire 52 are isolated or insulated from surrounding metallic elements of the cartridge 10 (e.g., the threaded base 17), so that no current passed to the heating element 50 from the electrode 40 is lost. The sleeves 60, 62 also ensure that the heating element 50 remains properly positioned within the cavity 23 during manufacture, filling, and shipping of the cartridge 10. In some embodiments, a third insulating sleeve (not illustrated) is wrapped around the electrode 40 and housed within the threaded base 17 to insulate the electrode 40 from the threaded base 17.
The configurations shown in FIGS. 2-5 illustrate a center post 20 that includes a base in which the housing for the threaded base 17 of the cartridge 10 is in-bored into the center post That is, the threaded base 17 is inserted at least partially within the distal base 26 of the center post 20, as best seen in FIGS. 4-5 . This configuration leaves the distal base 26 of the center post 20 exposed near the base of the cartridge 10. The bottom of the tank 15 interfaces with the top of the distal base 26 of the center post in this configuration.
FIGS. 6-7 also illustrate various configurations of cartridge tanks with measurements, in millimeters (mm), shown. FIG. 7 shows a configuration in which a distance between the distal atomizer housing portion 20 b to the inner surface or wall 15 a of the tank 15 is at least 1.8 mm. In some examples, the distance from the distal atomizer housing portion 20 b to the inner surface is greater than 1 mm, greater than 1.1 mm, greater than 1.2 mm, greater than 1.3 mm, greater than 1.4 mm, greater than 1.5 mm, greater than 1.6 mm, greater than 1.7 mm, greater than 1.8 mm, greater than 1.9 mm, or greater than 2.0 mm. In some configurations, the distance from the distal atomizer housing portion 20 b to the inner surface 15 a is about 1.2 mm to about 2 mm, or from about 1.3 mm to about 1.8 mm, or from about 1.5 mm to about 1.8 mm, or a distance within a range defined by any two of the foregoing values.
A greater distance between the distal atomizer housing portion 20 b and the inner surface 15 a allows a greater volume of oil to be stored in the tank body 15 between the inner surface 15 a and the distal atomizer housing portion 20 b. This can lead to an overall shorter column of oil within the cartridge 10, which can have thermodynamic advantages, while maintaining the same volume of oil stored within the tank body 15. For example, by having a shorter column of oil within the tank body 15, each oil particle has a shorter distance to travel in order to reach the heating element contained within the distal atomizer housing portion 20 b. As the oil has a shorter travel distance, more oil will complete the full travel distance to contact the heating element and be vaporized. Correspondingly, less oil will be lost due to adherence of the oil to the inner surface 15 a of the tank body 15.
Similarly, there may be a greater distance between the proximal vapor outlet portion of the center post 20 and the inner surface 15 a of the tank body 15. The presence of the shoulder 22 between the proximal vapor outlet portion 20 a and the distal atomizer housing portion 20 b allows for variable distances between the inner surface 15 a and portions of the center post 20. In some examples, the distance from the proximal vapor outlet portion 20 a to the inner surface 15 a is greater than 2.1 mm, greater than 2.2 mm, greater than 2.3 mm, greater than 2.4 mm, greater than 2.5 mm, greater than 2.6 mm, greater than 2.7 mm, greater than 2.8 mm, greater than 2.9 mm, greater than 3 mm, greater than 3.1 mm, greater than 3.2 mm, greater than 3.3 mm, or greater than 3.4 mm; the distance between the proximal vapor outlet portion 20 a and the inner surface 15 a may be within a range defined by any two of the foregoing values. As before, a greater distance between the proximal vapor outlet portion 20 a and the inner surface allows a greater volume of oil to be stored in the cartridge 10 between the inner surface 15 a and the proximal vapor outlet portion 20 a, resulting in an overall shorter column of oil within the cartridge 10, which can have thermodynamic advantages.
The greater distance between the proximal vapor outlet portion 20 a of the center post and the inner surface 15 a of the tank also has been found to improve the filling process. The tanks may be filled by hand, or they may be filled by automated machines. During filling, oil is inserted into the tank between the center post and the inner surface 15 a of the tank. That is, the oil must be injected between the center post and the inner surface 15 a of the tank. With a larger space between the center post and the inner surface 15 a of the tank, the filling can be done more easily and faster and a lower cost. Because there is a greater space, the degree of error is increased. Whether for human manual filling or automated machine filling, a greater degree of error allows for faster filling at lower costs.
In some configurations, the length of the proximal vapor outlet portion 20 a is less than 30 mm, less than 25 mm, or less than 20 mm (see FIG. 6 ). In one configuration the length is about 18-20 mm. This reduced length of the proximal vapor outlet portion 20 a can have several advantages. For example, a shorter proximal vapor outlet portion 20 a of the center post 20 means the entire center post 20 is closer to the atomizer located within the atomizer housing portion of the center post 20. This may allow more effective heating of the entire center post 20. The proximal end of the center post (which is also the proximal end of the proximal vapor outlet portion of the center post) is closer to the atomizer and can heat more effectively compared to a longer center post. This increased heating of the proximal vapor outlet portion 20 a can reduce condensation and accumulation of oil within the vapor lumen 24 of the proximal vapor outlet portion 20 a.
In some embodiments, a length of the entire center post 20 ranges from 25-40 mm. The length of the center post 20 may be measured from the distal base 26 to the proximal end 21. In some embodiments, the distal base 26 is connectable to a threaded base 17, which connects the cartridge 10 to a power source. In such embodiments, the distal base 26 abuts the distal end 16 of the tank 15 and may be substantially flush with the distal end 16 of the tank 15.
Additionally, in some embodiments, the center post 20 can be made from ceramic or ceramic blends. The center post 20 being at least partially of a ceramic material also allows for more effective heating of the entire center post 20, as ceramic materials are capable of efficient thermal conductivity. Not only will the center post 20 heat more efficiently, the center post 20 will also heat more uniformly, meaning hot and/or cold spots within the center post 20 will be reduced or eliminated. A uniform heating of the center post 20 will reduce condensation and accumulation of oil within the entire center post 20 (e.g., within the entire vapor lumen 24). In other configurations, the center post 20 can be made from other materials, such as metals, plastics, etc.
The shorter center post 20 can also improve manufacturing techniques and increase reliability. A shorter center post 20 has been found to manufacture more reliably compared to longer center posts. Additionally, the proximal vapor outlet portion 20 a is relatively thin compared to the distal atomizer housing portion 20 b, and this proximal vapor outlet portion 20 a tends to fail more than other portions of the device (i.e., the proximal vapor outlet portion 20 a the portion of the center post 20 is more difficult to reliably manufacture and mold). By decreasing the length of the center post 20, and particularly the length of the proximal vapor outlet portion the center post 20 can be more reliably manufactured. For example, multiple molds can be reliably run and various materials, such as ceramics and ceramic blends, can be used for manufacturing the center post.
According to another aspect, the lumen 24 of the proximal vapor outlet portion 20 a of the center post 20 has an inner diameter greater than 2.4 mm, greater than 2.5 mm, greater than 2.6 mm, greater than 2.7 mm, greater than 2.8 mm, greater than 2.9 mm, or greater than 3 mm. In some configurations, the inner diameter is 2.7 mm (see FIG. 8 ). This larger inner diameter of the lumen 24 can reduce clogging within the lumen 24. Additionally, it can reduce the tendency for the lumen 24 to act like a straw and draw oil that has condensed within the lumen 24 proximally.
In some configurations, the base 26 of the center post 20, i.e. the distal end of the center post 20, is wider than 7 mm, wider than 7.5 mm, wider than 8 mm, wider than 8.5 mm, wider than 9 mm, wider than 9.5 mm, wider than 10 mm, wider than 10.5 mm, wider than 11 mm, wider than 11.5 mm, wider than 12 mm, wider than 12.5 mm, or wider than 13 mm. In one configuration the base of the center post has a diameter of 13 mm (see FIG. 7 ). This wide base 26 can have thermodynamic advantages. For example, the distal base 26 may be heated more efficiently and uniformly, which may keep oil near the atomizer in a flowable state. Maintenance of the flowable state may increase the vapor efficiency of the atomizer.
FIGS. 8-9 show perspective, exploded views of two cartridges, 10 and 10′, respectively, having different configurations on the distal end of the cartridge. FIG. 8 shows a cartridge that utilizes a center post similar to the one shown in FIG. 3 , with a base 26 that includes a slot 27 (not visible in the view of FIG. 8 ) to receive a projection 19 of the threaded base 17. This connection between the center post and the threaded base 17 leaves at least a portion of the base 26 of the center post 20 exposed or on an external side of the cartridge.
In contrast, FIG. 9 shows a configuration in which the center post 20′ has a distal end 26 which nests within the base 17. Rather than the center post extending down around the base as shown in FIG. 8 , the base extends up around the center post in FIG. 9 . This allows the center post 20 to compress fit within the base 17. This configuration can have less leakage due to the center post being compression-fit within the base 17. It may also have different durability, as less ceramic is exposed on the external side of the cartridge. This configuration may also have different thermodynamic properties. With more plated metal on the base extending around the distal end 26′ of the center post 20, this may act as a heat sink, for example.
The center post may be simple to manufacture and lead to fewer manufacturing failures through cracking. The wide base coupled with the shorter center post can lead to a more robust and replicable manufacturing process. The center post can be formed of ceramics, heat safe plastics/polymers, metal, and/or any other suitable material.
