Description

[0001] Aerosol-Delivery Device with Inclined Trigger Actuation Direction

[0002] The present invention relates an aerosol-delivery device, a method for delivering an aerosol to a body cavity of a consumer and the use of a pump element in an aerosol-delivery device to provide pressure for the release of an aerosol.

[0003] Aerosol-delivery systems, in particular nicotine delivery systems, come in various forms, including electronic and non-electronic varieties. These systems may be designed to help individuals combat their smoking addiction by providing an alternative source of nicotine while reducing exposure to harmful tobacco smoke.

[0004] Typical examples of electronic nicotine delivery systems comprise heat-not-burn products, electronic cigarettes, e-cigarettes, and vaping devices. These battery-powered devices are designed to vaporize a variety of nicotine-containing substances, including liquids, solids, and amorphous forms.

[0005] Regarding non-electronic devices, one notable category used as an aid for quitting smoking is the nicotine spray. These sprays are mechanical devices designed to dispense a nicotine solution as an aerosol from a container. Consumers typically need to position the spray nozzle in front of their mouth or nose. The goal of the spray is to deliver nicotine through absorption in the nasal mucosa or mouth, providing rapid relief from the symptoms of nicotine withdrawal.

[0006] Conventional aerosol-delivery devices, in particular nicotine sprays, generally include a container equipped with a liquid reservoir that holds multiple doses of a nicotine solution. The spray features a compressible nozzle, which is designed to trigger a pump mechanism. The mechanism efficiently transfers the liquid from the reservoir to the nozzle, thus allowing for the dispensing of a single dose of the nicotine solution with each actuation. In these conventional devices, the nozzle is compressed in the direction of the longitudinal axis of the aerosoldelivery device.

[0007] Such a design presents several limitations. Firstly, consumers are required to exert an axial compressive force to operate the nozzle and pump mechanism. This axial compression may inadvertently result in hand movement during operation, making it challenging for consumers to precisely direct the spray toward specific areas of the mouth or nose. Additionally, existing sprays are designed to be sprayed from a distance away from the consumer’s mouth. Such an orientation often leads to an unintended waste of the spray, causing it to be dispersed outside the mouth rather than precisely targeting the intended location. Furthermore, the use of conventional sprays may cause discomfort for users, as they are required to significantly open their mouths during application.

[0008] According to a first aspect of the invention, there is provided an aerosol-delivery device, in particular for delivering an aerosol to a body cavity of a consumer. The body cavity may be the consumer’s nose cavity and / or mouth cavity. The aerosol-delivery device comprises a dispenser and a trigger element. The aerosol-generating device extends primarily along a longitudinal axis. The trigger element may be configured to be actuated through a force applied to the trigger element in an actuation direction. The trigger element may be configured to be actuated through a displacement of the trigger element or at least a part of the trigger element in the actuation direction. The actuation direction is arranged at an angle with respect to the longitudinal axis. Within the context of the application, being arranged at an angle means in particular an angle different from 0 degrees and different from 180 degrees, which means in particular not parallel to each other. The actuation direction may be inclined with respect to the longitudinal axis. The displacement of the trigger element or at least part of the trigger element may be a translational motion, in particular only along the actuation direction.

[0009] The present invention provides an aerosol-delivery device with a trigger element that can be actuated in a direction inclined with respect to the longitudinal direction of the device. Specifically, a dispensing mechanism for supplying a nicotine solution within the spraying device can be operated by a lateral button, enabling the spraying device to discharge fluid in a longitudinal direction. By eliminating the need for axial compression, as is the case with conventional aerosol-delivery devices in the prior art, the aerosol-delivery device of the present invention provides an improved and more comfortable user experience, facilitating use of the device. In addition, the present innovation allows consumers to position the nozzle more precisely within their mouth or nose, enabling them to achieve greater accuracy regarding the aerosol delivery.
