Lighter with mini perfume spray

Abstract

Portable hybrid device comprising an ignition mechanism and an integrated atomizing system, provided with a main body housing a fuel reservoir (A) and a cosmetic reservoir (B) that are physically separate from each other, characterized by a mechanical safety mechanism coupled to a pivoting closure cap (C), wherein the mechanism comprises: • a hinge cam rigidly connected to the closure cap; • a translationally movable transmission slide; • a locking pin rigidly connected to the slide; wherein the mechanism is configured such that a rotation of the closure cap (C) into an open position displaces the locking pin in such a way as to block the stroke of an actuating button (D) for activating the atomizing system, thereby preventing any atomization of cosmetic liquid when the ignition mechanism is exposed.

Description

1. Title of the invention Lighter with mini perfume spray 2. Technical field The present invention relates to the field of portable ignition devices (gas, petrol or electric lighters) that integrate an additional liquid atomization function. In particular, it relates to a multifunctional hybrid device that combines a flame ignition system and a miniature perfume storage and atomization system, wherein both systems are thermally and mechanically isolated from each other to ensure operational safety. 3. State of the art Devices are known that occasionally integrate minor additional functions. However, hybrid objects that combine a heat source (lighter) with a highly flammable liquid (alcohol-based perfume) have significant disadvantages, which the present invention aims to overcome: • Risk of unintentional ignition: Existing systems do not ensure that the atomizer is blocked during active flame operation, which poses a risk of flame flashbacks or explosions. • Thermal decomposition of the liquid: The heat generated during prolonged lighter operation is often transferred to the casing, altering the olfactory properties of the perfume or causing a dangerous increase in internal pressure within the cosmetic container. • Odor contamination: In the case of inadequate sealing, fuel emissions (gas or gasoline) contaminate the fragrance and render it unusable. 4. Technical problem to be solved The objective of the present invention is the construction of a compact “2-in-1” object that ensures the following features: • Absolute safety in use through physical inhibition of the atomizer during the ignition phase. • Effective thermal protection of the perfume reservoir to preserve the chemical integrity of the fragrance. • Increased tightness that meets the pressure requirements, particularly in air transport. 5. Solution to the problem (disclosure of the invention) To solve these problems, the invention proposes an architecture with two reservoirs (reservoir A for the fuel and reservoir B for the cosmetic) which are strictly separated by a high-performance thermal partition (G) (preferably made of PEEK, technical ceramic or borosilicate glass). The key innovation is based on a hinge-controlled mechanical locking mechanism (so-called "hinge-lock" system). This system establishes a physical dependency between the cap (C) and the atomizer's operating button (D): • In the open position (lighter operation): The movement of the hinge immediately blocks the atomizer's pump mechanism. Perfume atomization is physically impossible. • In the closed position: The lock is released, allowing the atomizer to be used via the operating button (D). This physical and mechanical separation ensures that the ignition zone and the atomization zone can never be operated simultaneously. 6. Advantages of the invention • Preventive safety: Complete elimination of the risk of the spray mist being ignited by the lighter flame. • Fragrance preservation: The heat shield (PEEK / borosilicate / technical ceramic) prevents a temperature increase in the cosmetic liquid and extends its shelf life. • Sustainability and ecology: The system is designed as a dual-refillable device (fuel and perfume), thus reducing waste from disposable lighter and atomizer components. • Transport versatility: Thanks to its robust and sealed construction, the device is ideally suited for everyday transport and meets civil aviation safety standards. Description 1. Architecture and internal subdivision The invention is based on a one-piece or assembled housing vertically divided by an insulating structural partition (G). This partition separates the device into two sealed chambers: • Chamber A (ignition unit): Located on the hinge side, it contains the fuel reservoir. In the case of a petrol lighter, it includes absorbent cotton and a wick. In the case of a gas lighter, it contains a pressure vessel and a vent valve. In the case of an electric lighter, it includes a rechargeable battery. • Chamber B (cosmetic unit): Located on the side opposite the hinge, it contains a reservoir for perfume. The reservoir is designed to be either refillable or replaceable. This reservoir is equipped with a pre-compression micro-pump that ensures fine atomization without dripping. 2. Safety mechanism (“hinge-lock”) The safety mechanism is based on a direct mechanical coupling between the hinge of the lighter's cap (C) and the stroke of the atomizer's trigger button (D). This interaction is designed to physically prevent any axial movement of the cosmetic pump piston when the ignition zone is exposed: • Resting configuration (cap closed): The trigger button (D) is free to move in its axial stroke. The user can trigger the spray. • Ignition configuration (cap open): Opening the cap actuates a rotating cam rigidly connected to the hinge. This cam moves a locking rod or pivot lever that slides under the trigger button (D) or blocks the micropump piston. This physical locking makes atomization impossible while the flame zone is exposed, thus eliminating any risk of flame flashback into the alcoholic spray cloud. 3. Thermal protection and sealing To prevent the cosmetic liquid (which is flammable and heat-sensitive) from heating up, the partition (G) is designed as a heat shield. It can consist of a double wall with an insulating air gap or of an insert made of high-performance polymers such as PEEK (polyetheretherketone), borosilicate glass, or technical ceramics. The cosmetic reservoir is equipped with a spring-loaded conical seat seal. This ensures that even with slight thermal expansion, no leakage or evaporation of the alcoholic phase occurs. 4. Ergonomics and filling The sprayer's nozzle (E) is positioned laterally, so that the perfume stream is directed at an angle of 90° or 180° to the vertical axis of the flame. The base of the device has two separate filling ports: a standard valve for gas / petrol and a ball or lip valve for perfume, which allows refilling by simple pressure from a standard perfume bottle. Summary The invention relates to a portable hybrid device that combines a lighter and an integrated perfume atomization system in an ultra-compact housing. The device comprises two separate reservoirs (A for fuel, B for cosmetics) that are strictly isolated from each other by a thermal partition (G) made of high-performance materials (e.g., PEEK or ceramic) to prevent thermal decomposition of the fragrance. The key safety feature is a mechanical hinge-lock system coupled to the cap (C). A hinge cam and locking slider physically block the atomizer's activation button (D) once the cap is opened (ignition mode). This eliminates any risk of the spray mist being ignited by the flame. Additional safety features include a pressure relief valve with an internal absorption chamber for use in case of extreme heat exposure, as well as optional electromagnetic shielding for arc igniters. The system is fully refillable via separate interfaces at its base, enabling sustainable use. The invention thus offers a safe and ergonomic combination of a heat source and a volatile liquid for everyday use.
