[0001] Smart, Reusable, and Refillable Dual -Fragrance Scent Dispensing Apparatus with Customizable Pods and Magnetic Locking System

[0002] CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY

[0003] The present application claims priority from the Indian provisional patent application no. 202411071886.

[0004] FIELD OF THE INVENTION:

[0005] The present teachings relate to a dual -fragrance scent dispensing apparatus, and more particularly, though not exclusively, to a device designed for portable and convenient dispensing of two distinct fragrances in a controlled and efficient manner.

[0006] BACKGROUND OF THE INVENTION

[0007] The subject matter discussed in the background section should not be assumed to be prior art merely because of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the fragrance system that is convenient, customizable, and caters to the requirements of a modem lifestyle.

[0008] The need for portable fragrance dispensing devices has significantly increased as individuals seek more convenient and efficient ways to manage personal scents throughout the day. Traditional fragrance dispensers, such as spray bottles or rollons, present various limitations, including bulkiness, limited fragrance capacity, and the inconvenience of carrying multiple devices for different scents. Most existing solutions are single-use or non-refillable, contributing to environmental waste and offering little flexibility for users who prefer to switch between multiple fragrances based on their preferences or the occasion.

[0009] Traditional perfume bottles are designed to hold only one type of perfume and are typically discarded once the fragrance reaches a certain minimum level, making them fit for single-time use. This design restricts users to a single fragrance and does not provide the flexibility to switch between scents according to their mood, occasion, or personal preference. Moreover, luxury perfumes are often sold in large quantities (50ml-100ml) with a high price range, making it a long-lasting investment that may not align with the changing preferences of consumers over time.

[0010] In the luxury fragrance market, offline purchase dominates, limiting the number of perfumes users can experience due to the constraints of physical stores. Customers may only have the opportunity to try out a limited range of 5-10 perfumes, further limiting their choices. Additionally, the bulky packaging of traditional perfume bottles poses challenges for travelers who wish to carry multiple fragrance options conveniently. Carrying several bottles becomes impractical and inconvenient, especially when users desire to use different perfumes for various moods, timings, or occasions. Even carrying a single perfume bottle in a pocket can be unrealistic due to its size and shape.

[0011] While smaller sample containers exist, they are typically manufactured as promotional items or for sampling purposes. The high packaging cost-to-contents ratio and the impracticality of buying such small quantities of perfume discourage users from purchasing these smaller containers for regular use.

[0012] Furthermore, the lack of personalization options is a limitation of traditional perfume bottles. Consumers are limited to purchasing perfumes in pre-formulated flavors provided by the manufacturers. This restricts users from tailoring the fragrance to their own preferences and needs. The process of carrying or buying multiple different perfumes at the same time becomes tedious, and there is no guarantee of accurately measuring and using the desired amount of each component.

[0013] Furthermore, leakage and inefficient dispensing mechanisms have been persistent issues with traditional fragrance dispensers. These devices often lack secure closure systems, leading to accidental spills or fragrance loss during transport. Another challenge with current fragrance devices is the inability to track fragrance usage. Users are often left guessing how much product remains, which can lead to unintentional depletion at inopportune moments.

[0014] With the rise of smart, compact devices in personal care, there is a demand for a solution that combines portability, ease of use, and modern technology. Consumers are increasingly looking for eco-friendly alternatives that allow them to reuse and refill their products instead of constantly discarding single-use bottles. Additionally, users need a dispensing mechanism that not only holds multiple fragrances but also provides a reliable way to track usage and alerts them when refills are needed.

[0015] To overcome these limitations, the subject invention proposes a convenient-to-carry pod-style fragrance system. This system allows users to carry desired perfumes from different sources in smart pod-like arrangement. Users have the flexibility to customize their fragrance collection according to their requirements, preferences, and changing moods. The pod-style system offers a compact and travel-friendly solution, enabling users to conveniently carry a variety of fragrances in their handbags, pockets, or travel bags. By allowing users to select and interchange different scents, the system provides versatility and caters to the demands of a modern lifestyle.

[0016] Moreover, the proposed fragrance system can help reduce costs as users can purchase smaller quantities of perfumes and refill the pods as needed, rather than investing in large bottles that may last for an extended period without being fully utilized. This approach provides a cost-effective alternative and minimizes waste by promoting a sustainable refillable system.

[0017] Overall, the pod-style fragrance system addresses the limitations of traditional perfume bottles by offering convenience, customization, versatility, and costeffectiveness. It provides users with the opportunity to carry multiple fragrances, personalize their scent experience, and adapt to their changing preferences and needs.

[0018] The present invention addresses these shortcomings by providing a reusable, refillable, and highly portable dual -fragrance scent dispensing apparatus. It not only holds two distinct fragrances but also integrates advanced mechanical features such as magnetic locking systems, smart spray counting sensors, and LED indicators to inform the user of fragrance levels. This invention caters to users' demands for convenience, environmental responsibility, and smart technology in their fragrance management routines.

[0019] The dual -fragrance scent dispensing apparatus thus represents a significant improvement over the current state of the art, addressing the need for portability, ease of use, refillability, and smart features in a single, efficient device.
