BEST MODE FOR CARRYING OUT THE INVENTION

[0009] In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. Throughout this description, the embodiments and examples shown should be considered as exemplars, rather than as limitations on the invention. That is, the following description provides examples, and the accompanying drawings show various examples for the purposes of illustration. However, these examples should not be construed in a limiting sense as they are merely intended to provide examples of the invention rather than to provide an exhaustive list of all possible implementations thereof.

[0010] Specific embodiments of the invention will now be further described by the following, non-limiting examples which will serve to illustrate various features. The examples are intended merely to facilitate an understanding of ways in which the invention may be practiced and to further enable those of skill in the art to practice the invention. Accordingly, the examples should not be construed as limiting the scope of the invention. In addition, reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" or “in some embodiments” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

[0011] Referring to Figure 1, the pre-roll filling device 100 includes a base 101 with bilateral stanchions 102 and 103. Suspended between the stanchions 102 and 103 is a sleeve

104 which, in some embodiments is generally conical in shape and has an open top and an open bottom. In some embodiments, the sleeve 104 is mounted to a pivot pin 105 which rests on or is attached to the top of the stanchions 102 and 103. In some embodiments, the pin

105 facilitates rotation or swinging of the sleeve 104 to allow the sleeve 104 to be repositioned and/or agitated manually as further described herein. In some embodiments, an end of the pin 105 includes a wheel 105’ to facilitate manual rotation of the pin 105, and therefore the sleeve 104. Above the sleeve 104 is a hopper 106 which in some embodiments comprises a funnel-shaped element or may comprise a cup or other container. With reference to Figures 2A-2D, in some embodiments, the hopper 106 is configured as an extender- adapter to receive a larger pre-roll cone as further described herein. In some embodiments, the top of the sleeve 104 and/or the hopper 106 is threaded or has other attachment components, such as magnetic connections, to removably receive and retain corresponding threads or attachment components on the thereon and/or to removably receive and retain other devices such as the discharge section of a grinder 300 or container such as that described in Applicant’s U.S. Patent Application Nos. 16/285,582, 16/285,609, 16/285,628, 16/285,651, 16/285,678, which applications are hereby incorporated by reference in their entirety. This functionality is shown in detail in Figures 2A-2D.

[0012] In some embodiments, an electronic scale 107 is disposed beneath the sleeve 104 and used to weigh the contents of the pre-roll during the filling process as further described herein. The scale 107 is incorporated into the base 101, which base 101 houses certain electronic components of the device 100, including a power source 108, such as a battery or external power supply (for example, a USB-C charger), a microcontroller 109, a communications device 110, a display 111, one or more buttons 112, and a sensor array 113. [0013] Also included is a lighter 114, which can comprise a heating element which is triggered by a motion or proximity sensor or by a physical button inside the cavity of the lighter. This allows the lighter to activate when it senses the insertion of a pre-roll cone, cigarette or like smoking implement. In some embodiments, the heating element is triggered by a momentary, closed circuit switch. The lighter 114 may also include a circuit, shown in Figure 3, which includes a UV-LED, a temperature sensor, a humidity sensor, an infrared volume sensor, and a smoke detection sensor.

[0014] The microcontroller 109 provides power and communication connectivity for the various system components including the communications device 110, display 111, and sensor array 113. In some embodiments the microcontroller 109 comprises a processor (CPU), memory, and control programming for the various input and output peripherals. The communications device 110 may comprise a modem, Wifi chip, a Bluetooth chip, a NFC chip, a Universal Serial Bus (USB) port, or combinations thereof. In some embodiments the communication device 110 is configured to communicate with an external computing device such as a computer or smartphone in order to send and receive data including status information, scale information, and commands. Such data transmission can be accomplished through a customized application running on the smartphone or computer.

[0015] The display 111 may comprise an LED, LCD, OLED, or like display that can be used to output various information including contents weight, battery status, communications status, and the like. The buttons 112 are used as onboard control interface and may be multi-function and programmed to operate different functions based on the number and duration of presses. In some embodiments one or more of the buttons 112 is a multi-touch touch screen for added functionality.

[0016] In some embodiments, the sensor array 113 functions as a scale transducer to measure the mechanical energy, i.e. the pressure applied to the scale 107 by the contents placed thereon, and converts the pressure to an electrical output (e.g. current or voltage differential). The electrical output at the sensor is processed into a digital signal by the microcontroller 109 which digital signal can then be outputted on display 111 or through the communications device 110.

[0017] In some embodiments, an electronics-enabled cover 400 is provided, which is removably received over the hopper. The cover 400 can also include a microcontroller, one or more indicator lights (such as LEDs), a sanitizing UVC light, an infrared volume sensor, a fan or air pump, a vibration unit, a power source (for example, a battery and/or external power source such as a USB-C charger), and one or more buttons. These features allow for manipulation of the contents of the hopper 106, such as by applying air flow or vibration to agitate ingredients to facilitate filling or to provide air flow to the surrounding environment. The UVC light may be used to sanitize the ingredients in the hopper 106 and/or sleeve 104 prior to filling, or to otherwise sanitize the surfaces of the components of the device 100.

[0018] In use, the user places a pre-roll cone (cigarette paper) 201 into the sleeve 104 and then fills the pre -roll cone 201 with ingredients (tobacco, cannabis, herbs, cloves, medicaments, etc.) from the hopper 106. The ingredients displace downward into the pre-roll cone 201 which is supported by the sleeve 104. In some embodiments, the scale 107 is employed to weigh the contents of the pre-roll cone 201 and when the desired weight is reached, the now-filled pre-roll cone 201 is removed from the sleeve 104 and set aside. In that way, the end of the pre-roll cone 201 rests against the scale 107 in order for the contents to be weight. Accordingly, as shown in Figure 1, in some embodiments, an end of the pre-roll cone (where 201 points) extends beyond the open bottom of the sleeve 104. The cover 400 can be employed to facilitate filling through airflow or vibration.

[0019] Optionally, a removable ashtray accessory 500 may be employed may be a standalone device or which may be disposed inside or adjacent to the device 100 and may be attachable to the thereto, for example, by magnets or the like that attach to the base 101 or other component thereof. In some embodiments, the ashtray accessory 500 includes one or more receptacles 501 which can be used to store a cigarette or cigar. In some embodiments the ashtray accessory 500 includes an additive such as a desiccant, odor eliminator, air freshener, flavorant (i.e. flavoring agent), or colorant. In some embodiments, the additive is a liquid or gel ingredient that can emit flavorants and/or colorants that can change or enhance the flavor, odor, and/or color of the material filled into the pre-roll cone 201. In some embodiments, the ashtray accessory 500 may include a small battery-powered fan 502 to ventilate the ashtray and/or circulate the additive.

[0020] As noted above, the container includes connectivity features such that the communications device 110 can communicate with an outboard smartphone or computer for added functionality. In some embodiments the device is “app-enabled” and works in conjunction with control and notification software. The user can utilize an application running on a smartphone or computer to obtain information from the container such as weight, battery status, or the like. In some embodiments, the scale 107 obtains a weight measurement and stores corresponding weight data in the memory of the microcontroller 109. Then, each time of the user loads the application on his computing device, the stored weight information is automatically synchronized to the application.

[0021] It is appreciated and understood that the present invention provides an easy to use, feature-rich filling device for the filling and management of herb such as tobacco, hemp, Chinese herbal medicine, spices etc. for smoking or other uses. Convenience features such as the integrated scale, display, onboard communications, and various storage areas provide an

“all-in-one” solution that addresses many wants and desires in the art.
