Description

1. Title of the invention Writing instrument with integrated mini perfume atomizer 2. Technical field. The present invention relates to the field of writing instruments (ballpoint pens, fountain pens, felt-tip pens or gel pens) with an integrated additional function for liquid dispensing. More precisely, it relates to a hybrid instrument that combines a system for storing and atomizing miniature perfume, which is ergonomically and safely integrated into the object's body. 3. State of the art Simple writing instruments with integrated liquid reservoirs already exist on the market. However, these devices have significant disadvantages, which the present invention attempts to overcome: • Lack of safety: Existing systems often allow accidental spraying when the pen is carried in a pocket or bag. • Premature evaporation: The volatile nature of perfumes (alcohol) leads to rapid liquid loss when the pen is not properly sealed. • Complex refilling: Most models are disposable or require complete disassembly, which carries the risk of damaging the writing mechanism. 4. Technical problem to be solved The problem that the present invention purports to solve is the design of a "2-in-1" writing instrument that ensures the following: • Complete safety against unintentional activation of the atomizer. • A hermetic seal to preserve the fragrance long-term. • Smooth ergonomics that allow switching from the writing function to the perfume function through simple and intuitive handling. 5. Proposed technical solution To solve these problems, the invention proposes an instrument consisting of two separate bodies whose functions are mechanically coupled via a helical control cam. The unlocking of the perfume pump is physically linked to the extension of the writing tip. This architecture makes it possible to use the rotary motion required for writing as a "security key" for the atomizer. 6. Advantages of the invention • Increased safety: It is impossible to accidentally perfume yourself (or stain your clothes) unless the pen is in the "ready to write" position. • Sustainability: An infinitely refillable system that reduces plastic waste. • Quality preservation: The perfume's olfactory properties are maintained through enhanced insulation. • Compact design: Integration of a reservoir of up to 20 ml without compromising the instrument's aesthetics. DESCRIPTION The present invention relates to the field of precision writing instruments with an integrated cosmetic function. In particular, it relates to a writing instrument equipped with a secure and refillable atomizing device for liquids (perfume). Detailed description of the invention The instrument consists of a tubular body which is divided into two main sections: an upper part (1) which serves as a casing for the cosmetic function, and a lower part (2) or shaft which is dedicated to the writing function. 1. Architecture of the atomization system (FIG. 1) The upper part (1) houses a miniature atomizing system comprising: • An internal reservoir (3): With a capacity between 5 ml and 20 ml. According to the invention, this reservoir can be made of inert materials such as glass (soda-lime glass, borosilicate glass), engineering polymers (PET, PMMA), or metals (aluminum, stainless steel, precious metals). • A micropump (4): Attached to the upper end of the reservoir and connected to a dispensing nozzle. • A spray opening (6): Arranged laterally in the wall of the upper part (1), preferably opposite the mounting clip (10) for optimal ergonomics. • A trigger element (5): In the form of a push button located at the axial end of the body. 2. Safety mechanism with helical control cam (7) The originality of the invention lies in the mechanical coupling of the two functions (writing and perfume). An internal helical control cam (11) couples the movement of the lower part relative to the upper part: • Working position: A rotation of the body (for example, to the right) simultaneously extends the writing tip (8) (ballpoint, nib, felt, or gel tip) and mechanically unlocks the micropump. The pump pin aligns with a slot in the control cam, which allows the push button (5) to be pressed. • Resting position: A rotation in the opposite direction (to the left) retracts the tip and places a rigid stop under the pump mechanism, thus preventing any accidental atomization. 3. Sealing and thermal insulation The invention comprises a conical seat seal (or a high-performance O-ring) that interacts with the atomizer unit. This seal performs two functions: • Preventing liquid leakage due to pressure fluctuations (air transport) or temperature fluctuations. • Hermetically sealing the alcoholic phase of the perfume to prevent premature evaporation when the instrument is at rest. 4. Simplified refill system (FIG. 2) • The reservoir (a) is designed to be refilled without disassembling the atomizer. The base of the reservoir has a one-way filling valve (b). • The process involves placing the base of the instrument onto the exposed pin of an external reservoir vial. • Vertical pressure transfers the fluid directly from the reservoir vial (c) into the internal reservoir by pumping action or pressure differential, ensuring clean and rapid refilling. 5. Variants and ergonomic options The upper part can optionally integrate a translucent viewing window for level monitoring. Furthermore, the fastening clip (10) can be configured in one variant to serve as a radial actuating lever, either in addition to or replacing the axial push button (5).

The invention relates to a writing instrument with an integrated perfume atomizer, comprising a top part equipped with an internal reservoir, a micropump, and a lateral outlet opening. The invention is characterized by a helical curve mechanism that extends the writing tip and simultaneously unlocks the activation of the micropump only in the working position, thereby preventing accidental atomization in the resting position. The device can include a mounting clip that acts as a radial operating lever, as well as a viewing window for monitoring the liquid level. The reservoir can be refilled via a one-way valve without disassembly. A conical-seat sealing system ensures the hermetic isolation of the liquid when at rest, preventing evaporation of the alcoholic phase. This instrument enables a safe and ergonomic synergy between the writing function and the application of a customized fragrance. Advantages of the invention • Discreet: The mini perfume spray has an inconspicuous design. • Dual function: Combines writing and perfume in one item. • User-friendly: Simple and quick to use every day. • Unisex: Ideal for both women and men. • Space-saving: Compact solution that saves space in your bag. • Practical: Can be securely attached to a blouse or jacket pocket. • Versatile: A perfect gift or a high-quality promotional item. 1 Top part: Receptacle for perfume capsule (cap). 2.
