[0002] The present invention relates to the field of personal grooming and hygiene tools, particularly to a novel shampoo dispensing scalp brush designed for convenient and efficient hair and scalp cleaning. It is specifically geared toward combining the functionality of a brush and a shampoo dispenser into a single, travel-friendly unit. This invention enhances user convenience by incorporating a refillable tank, ergonomic design, and replaceable parts that provide a more effective and hygienic grooming experience. The field encompasses portable grooming tools for personal care, particularly in the domain of travel-ready scalp and hair cleansing.Description of the Related Art

[0003] Personal grooming tools have evolved significantly over the past few decades, with growing emphasis on convenience, portability, and multifunctionality. In the realm of hair care, the traditional process of shampooing often involves several separate components: a bottle of shampoo, manual application, and a brush or scrubber for scalp stimulation. This multi-step process, while effective, can be time-consuming, messy, and inefficient, particularly in fast-paced environments like gyms, travel settings, or during outdoor activities. The desire for streamlined, all-in-one personal care tools has spurred innovation in this area, driving the market toward compact, user-friendly devices that combine multiple functionalities in a single unit.

[0004] Scalp hygiene plays a crucial role in maintaining overall hair health, and improper shampoo application or inadequate scalp stimulation can lead to issues like dandruff, clogged follicles, and even hair loss. The invention becomes particularly important for individuals who value cleanliness and grooming while on the move. The need for a compact, travel-safe, and refillable shampoo dispenser that can also serve as a scalp massager is highly relevant in today's fast-paced lifestyle. Furthermore, the ergonomic application of such devices can aid users with limited mobility or dexterity, providing ease of use without compromising hygiene or effectiveness.

[0005] The global hair care market is expected to surpass $100 billion by 2027, with a significant segment dedicated to scalp health and grooming tools. In recent years, several companies have launched scalp massagers and shampoo brushes, mostly made of silicone, focusing on tactile benefits and deep cleaning. Products like the “Heeta Scalp Brush” or “Vitagoods Scalp Massager” have gained popularity for their massage function, but they generally lack integrated shampoo dispensing mechanisms. Others have introduced shampoo bottles with built-in brushes; however, these are often bulky, non-refillable, or poorly designed for travel. While each of these tools offers partial solutions, none have seamlessly merged the elements of ergonomic design, TSA-compliant liquid storage, replaceable hygiene components, and one-handed usability into a single cohesive device.

[0006] The scalp brushes available today help promote blood circulation, exfoliate the scalp, and enhance shampoo lathering. They are usually constructed with soft silicone, making them gentle on the skin while being durable and easy to clean. Some electric versions offer vibrational massage, and a few have simple integration with shampoo application through external or squeeze-based mechanisms. These products cater to a wide audience looking for salon-like scalp care at home, and their general affordability and ease of use have contributed to their popularity.

[0007] Despite these advancements, users continue to face limitations. Most products require the use of a separate shampoo bottle, leading to messiness and wasted product. Furthermore, existing brush-based devices often fail to provide consistent shampoo flow, lack ergonomic grip for comfortable handling, and are not designed with portability in mind. Many of them are non-refillable or incompatible with TSA guidelines, limiting their utility during travel. Hygiene is another concern—brush heads are rarely replaceable, posing challenges for maintenance and long-term use. For users with physical limitations or time constraints, the lack of a truly multifunctional device means the hair-cleaning process remains inconvenient and fragmented.

[0008] The present invention, ShamPal, addresses these gaps with a novel, travel-friendly, and ergonomically designed shampoo-dispensing scalp brush. ShamPal integrates a 3.5-ounce refillable tank—perfectly aligned with TSA liquid restrictions—directly into the brush body. It features a three-way multifunctional knob that acts as a grip, seal, and a spring-activated dispensing mechanism, enabling one-handed use. At the base is the “ShamPad,” a replaceable silicone brush pad with an X-shaped slit that seals itself and dispenses shampoo directly onto the scalp. Its curved brush structure and variable-length bristles conform to the natural contour of the human head, providing a deep yet gentle cleaning experience. The entire unit is compact, easy to refill, and ideal for travel, gym, or home use.

[0009] The proposed invention uniquely bridges the divide between convenience, portability, and hygiene in scalp grooming. Unlike existing tools that offer only isolated features, this invention provides a fully integrated system that combines shampoo storage, application, and scalp stimulation in one compact design. It fulfills unmet user needs such as refillability, ergonomic handling, replaceable components, and compliance with travel regulations. By eliminating the need to carry separate shampoo bottles and scalp brushes, it reduces clutter and enhances user experience. ShamPal serves a wide range of consumers—from busy travelers to seniors and individuals with limited dexterity—making it a truly universal grooming solution. Its modular construction and sleek design also pave the way for a sustainable, long-term alternative in the personal care market.

Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

[0031] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. As used herein, the singular forms “a,”“an,” and “the” are intended to include the plural forms as well as the singular forms, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and / or “comprising,” when used in this specification, specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0032] The present invention is a portable, handheld grooming device designed to dispense shampoo directly onto the user's scalp while simultaneously scrubbing and massaging the area with an integrated brush. This device combines multiple hair care functions—storage, dispensing, scrubbing, and massaging—into a single compact unit that is refillable, travel-compliant, and user-friendly. It eliminates the need for separate shampoo bottles and scalp brushes, streamlining the hair-washing process and improving hygiene, portability, and efficiency.

[0033] As per its preferred embodiments, the assembly is composed of three main structural components: a refillable holding tank, a multi-functional dispensing knob, and a replaceable brush pad known as the ShamPad. The holding tank forms the body of the device and is made from a transparent or semi-transparent plastic material, allowing the user to visually assess the remaining volume of liquid. This tank is designed with a capacity of 3.5 fluid ounces (103.5 mL), making it compliant with TSA liquid regulations for carry-on travel, thereby enhancing its usability for travelers.

[0034] As per its further embodiments, the multi-functional knob located at the top of the device serves three primary purposes: it functions as a grip handle, a filling cap, and a dispensing actuator. The knob is ergonomically shaped, similar to finger grips used on the back of smartphones, allowing the user to hold and press the device comfortably with one hand. Internally, the knob houses a spring-loaded mechanism consisting of a coil spring wrapped around a flat-headed pin or plunger. When the knob is pressed, the spring compresses and pushes the pin downward through a dispensing outlet, allowing the liquid shampoo to flow through to the brush pad.

[0035] As per its further embodiments, the refillable tank is designed with a threaded port at the top, into which the dispensing knob screws securely. This design ensures both a leak-proof seal and easy access for refilling the shampoo or liquid contents. Users can simply unscrew the knob to pour shampoo into the tank, then reseal the unit. The tank's shape resembles a peanut or ergonomic pebble, allowing it to rest naturally in the palm for effortless maneuverability during use. This tank not only holds the liquid but also provides the structural integrity for the overall device.

[0036] As per its further embodiments, the proposed design is a detachable silicone brush pad that mounts at the bottom of the device. It features variable-length bristles arranged to match the natural curvature of the human scalp, making it effective in reaching uneven areas while providing a gentle scrubbing sensation. At the center of the ShamPad is a circular concave area designed to guide the actuator pin during dispensing. The X-shaped slit at the center acts as a self-closing valve, allowing shampoo to be dispensed when pressed from above but sealing itself afterward to prevent leakage or waste. The ShamPad can be easily removed and replaced, supporting long-term hygienic use.

[0037] As per its further embodiments, to operate the assembly, the user simply fills the tank with shampoo, secures the knob, and holds the device with their fingers gripping the top knob. During use, the user can apply the ShamPad directly to the scalp and press down on the knob, which actuates the spring-loaded pin. This action opens the X-shaped slit and allows shampoo to flow from the tank through the brush pad and onto the scalp. As soon as the knob is released, the spring pushes the pin back to its resting position, and the slit reseals. The silicone bristles then help spread the shampoo evenly and provide a soothing massage effect.

[0038] As per its further embodiments, one of the key innovations is its focus on hygiene and modularity. The replaceable part ensures that users can maintain a clean grooming surface, avoiding bacterial buildup or product residue. It also allows users to choose from different pad types—such as softer or firmer bristles—based on personal preference or sensitivity. The transparent tank makes it easy to clean and refill, and the spring-loaded mechanism is protected within the sealed knob housing, minimizing mechanical wear and exposure to moisture. The entire device is designed for tool-free disassembly, supporting ease of maintenance and cleaning.

[0039] As per its further embodiments, the assembly is ideal for a variety of user scenarios, including travel, gym use, outdoor activities, and home grooming routines. It is especially beneficial for users with mobility limitations, such as elderly individuals or those with hand / wrist conditions, who may struggle with handling multiple grooming tools. By integrating shampoo dispensing directly into the brush, it eliminates messy handling, reduces product waste, and enhances convenience. The ergonomic grip, compact form factor, and hygienic design make ShamPal not just a novel grooming device, but a next-generation personal care solution that aligns with modern user needs and lifestyle demands.

[0040] While a specific embodiment has been shown and described, many variations are possible. With time, additional features may be employed. The particular shape or configuration of the platform or the interior configuration may be changed to suit the system or equipment with which it is used.
