Description

2. Technical field

[0001] 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.

[0002] 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 guarantee that the atomizer is blocked during the active flame, which poses a risk of flame flashbacks or explosions. • Thermal decomposition of the liquid: The heat generated during prolonged use of the lighter is often transferred to the casing, which can alter the olfactory properties of the perfume or cause the internal pressure in the cosmetic container to rise dangerously. • Odor contamination: If the seal is inadequate, fuel emissions (gas or gasoline) contaminate the fragrance and render it unusable. 4. Technical problem to be solved

[0003] The aim of the present invention is to construct 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 pressure requirements, especially in air transport. 5. Solution to the problem (disclosure of the invention)

[0004] To solve these problems, the invention proposes an architecture with two reservoirs (reservoir A for the fuel and reservoir B for the cosmetic) that are strictly separated by a high-performance thermal partition (G) (preferably made of PEEK, technical ceramic or borosilicate glass).

[0005] 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 pump mechanism of the atomizer. Perfume atomization is physically impossible. •. In closed position: The lock is released, allowing the atomizer to be used via the operating button (D).

[0006] 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 ignition of the spray mist by the lighter flame. • Preservation of the fragrance: The heat shield (PEEK / borosilicate / technical ceramic) prevents a temperature increase of 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 dense construction, the device is ideally suited for daily transport and meets the safety standards of civil aviation. Description 1. Architecture and internal subdivision

[0007] The invention is based on a one-piece or assembled housing that is vertically divided by an insulating structural partition (G). This partition divides 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 release valve. In the case of an electric lighter, it contains a rechargeable battery. • Chamber B (Cosmetic Unit): Located on the side opposite the hinge, it contains a reservoir designed for perfume. The reservoir is 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”)

[0008] 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 displacement of the cosmetic pump piston when the ignition area is exposed. • Resting configuration (cap closed): The actuating button (D) is freely movable in its axial stroke. The user can trigger the spraying process. • 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 actuating button (D) or blocks the micropump piston. This physical locking prevents atomization while the flame zone is exposed, thus eliminating any risk of flame flashback into the alcoholic spray cloud. 3. Thermal protection and sealing

[0009] 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.

[0010] 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

[0011] 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.
