Definitions

  • the present invention relates to a personal olfactory device.
  • olfactive stimuli can have a strong emotional impact on the human being. It is a common experience that a pleasant olfactory sensation favours the achievement of a state of well-being and relaxation. Some studies exploit olfactory stimuli to attain beneficial effects on tackling stress, bad mood, eating disorders or mild states of depression. Furthermore, evidence shows that aromatherapy carried out with appropriate scents can control the craving for nicotine in smokers thus providing a concrete assistance in the process of getting out of the nicotine addiction and in quitting smoke.
  • vaporizers which are commonly known as “electronic cigarettes.” Such devices are based on the principle of causing the evaporation of an aqueous solution by supplying heat and have the drawback of requiring a battery power supply. These devices therefore, require internal electronic parts for operation and tend to be quite expensive to be manufactured. Additionally, these vaporizers are essentially conceived to offer an alternative to cigarettes or as an aid to quit smoking, using for the latter purpose suitable solutions having a nicotine content progressively reduced. For this reason, they are essentially designed to reproduce the sensation of smoking a cigarette, for example they develop a cloud of vapour at each inhalation to give to the users the visual sensation of smoke. Consequently, they are unsuitable for an olfactory stimulation having a broader and more diversified purpose.
  • EP 2978461 discloses a device for diffusing aromatic vapours forming part of a multimedia system for entertainment or educational purposes. It is therefore a device designed to involve an audience of people and not suitable for personal use. It should be noted that the persistence of an aroma in the air can saturate the olfactive cells and make the desired effect of aromatherapy disappear, for which a device capable of giving intermittent inhalation is preferable.
  • US 7484716 discloses a wearable olfactory cartridge which, like in the previous case, is designed to be used in a multimedia context. Said wearable cartridge is controlled by a central unit, for example a computer, to provide olfactory stimuli in a context of an audio-visual presentation.
  • a central unit for example a computer
  • US 7154579 discloses another example of an olfactive system synchronized with an audio-visual system.
  • US 6 803 987 discloses a portable olfactory device with forced ventilation operation achieved by means of a fan.
  • the device essentially comprises an inhalation mask and a separate unit to be worn for example at the waist, which contains the fan, the respective battery, and other electrical and mechanical components necessary for operation. This is therefore a rather complex device and not very comfortable to use.
  • the object is achieved with a device according to the attached claims.
  • the device comprises a housing for an interchangeable cartridge containing an olfactive substance and a dispensing nozzle communicating with the outside.
  • the cartridge containing the olfactive substance communicates with the nozzle through a path comprising a Venturi-effect convergent channel.
  • the Venturi-effect convergent channel accelerates the flow of air containing the olfactive substance toward the nozzle.
  • This acceleration has the effect of concentrating the molecules of the olfactive substance and that this phenomenon improves the olfactory sensory experience and makes it more engaging at parity of substance consumed.
  • the device is integrally contained in a portable body and has no further external components. It does not require fittings or connections to external units.
  • the device comprises a diffusion chamber located between the cartridge and the convergent channel.
  • Said diffusion chamber acts as an accumulation chamber, collecting a mixture of air and olfactive substance emanated from the cartridge.
  • the olfactive substance is represented by vapours of a volatile essence contained in the cartridge.
  • the diffusion chamber is isolated from the convergent and from the nozzle by means of a normally closed passive valve: this avoids the dispersion of the olfactive substance when the device is not used.
  • the device further comprises a manual dispenser whose actuation has the effect of expelling at least part of the olfactory mixture contained in the diffusion chamber by temporarily opening said valve, in order to put the diffusion chamber in communication with the nozzle and pump the olfactory mixture towards the nozzle itself through the convergent.
  • the passage of the mixture into the convergent achieves the desired effect of accelerating the flow.
  • the device according to the invention requires no battery power and has no mechanisms or moving parts inside it. It is therefore lightweight, little bulky and easy to manufacture.
  • the device is suitable to be used as an olfactory device for personal use, for any aromatherapy application.
  • a device according to the invention can be advantageously made with a body with an elongated shape and with a length preferably from 100 mm to 150 mm, more preferably from 130 mm to 140 mm, for example about 135 mm.
  • the body can have an essentially cylindrical shape with a variable diameter, and with a maximum diameter ranging between 20 and 25 mm, for example about 23 mm. With these dimensions, the device has substantially the proportions of a cigar and is easy to be used in any situation both indoors and outdoors.
  • the device can be used, with the appropriate essences, to create a state of satisfaction or relaxation in the user, so to evoke certain sensations or memories, or even as a healthy alternative to smoking.
  • the use of the device comprises, for example, placing the device in proximity of a nostril and operating the dispenser causing the expulsion of an olfactory mixture comprising an olfactive substance contained in a cartridge mounted in the device.
  • the device can be positioned with the nozzle close to the nostrils, for example at a distance of about 3 cm.
  • the convergent channel which achieves the desired flow acceleration due to Venturi effect is preferably located near the dispensing nozzle.
  • the device may comprise a single nozzle or a plurality of nozzles, for example arranged in a crown.
  • the emission axis of the nozzle can be tilted with respect to the axis of the convergent channel.
  • the nozzle may have an increasing cross-section area from the inlet to the outlet. The effect of said tilted axis and of said embodiment with increasing cross-section area is to improve the diffusion of the olfactive substance and consequently to obtain a better experience of use.
  • the diffusion chamber is preferably located between the cartridge and the nozzle and more preferably between the cartridge and the convergent.
  • the path of the olfactive substance consequently crosses, in order: the diffusion chamber, the convergent channel and finally the dispensing nozzle towards the outside.
  • the dispenser comprises a pressure zone that is elastically deformable when a pressure is applied by the user and that defines a wall portion of the diffusion chamber.
  • the device also comprises a valve located between the diffusion chamber and the nozzle and arranged to isolate the diffusion chamber from the nozzle. Said valve is arranged to open during the actuation of the dispenser and to close when the actuation of the dispenser stops.
  • the valve is preferably located at the outlet of the diffusion chamber.
  • the valve is represented by an orifice in a portion of the wall of the diffusion chamber wall, the wall is made of elastically deformable material, for example silicone.
  • the orifice has a closed configuration when the wall portion is undeformed in rest conditions, and an open configuration when the wall portion is elastically deformed due to the actuation of the dispenser.
  • the wall portion for example is represented by a membrane. More preferably, said membrane rests on the inlet section of the converging channel.
  • the device comprises: a cartridge holder compartment, a spout that can be separated from said compartment, and a dispensing body.
  • the spout includes the nozzle and the convergent- divergent nozzle.
  • the dispensing body can be fitted on the spout and is made at least in part of an elastically deformable material, preferably silicone.
  • the dispensing body comprises the diffusion chamber and a pressure zone accessible to the user.
  • the diffusion chamber communicates directly with the inside of the cartridge (containing the olfactive substance) while it is essentially isolated from the nozzle through the valve previously described.
  • the user By pressing on said pressure zone, the user causes the valve to open, putting the chamber in communication with the emission nozzle; at the same time the pressure causes an expulsion of the olfactive mixture from the diffusion chamber toward the nozzle through the convergent channel.
  • a further aspect of the invention is represented by a bayonet coupling between the interchangeable cartridge, containing the olfactive substance, and the device.
  • the interchangeable cartridge can be inserted into said housing by means of a bayonet coupling which is formed between a first coupling element integral with the cartridge and a second coupling element mating with the first one and associated with the housing.
  • the bayonet coupling comprises a male coupling element associated with the cartridge and a female element, mating thereto, obtained in the housing adapted to receive the cartridge.
  • the coupling elements are configured to achieve a bayonet coupling with a quarter turn of the cartridge relative to the housing.
  • a sealing ring made of deformable material, for example silicone, which ensures the sealing.
  • the male element associated with the cartridge can be provided, for example, on a neck of the cartridge, which is shaped like a small bottle.
  • the male element can also be used to fix a cap of the small bottle, which is removed before insertion into the olfactory device.
  • the male element is in the form of two fins extending from the neck of the small bottle.
  • the advantages of the bayonet coupling are essentially the following: the coupling is simple and fast; the slight compression contact with the sealing ring prevents the dispersion of the olfactive substance or the contamination of the substance with the external air; the bayonet coupling can have a perceptible feedback (for example in the form of a “click”) indicating the correct positioning of the cartridge.
  • a personal olfactory device with an interchangeable cartridge comprising a housing for receiving a cartridge containing an olfactive substance and at least one dispensing nozzle for realising the olfactive substance or a mixture containing the olfactive substance, wherein the cartridge can be inserted into said housing by means of a bayonet coupling between a first coupling element integral with the cartridge and a second coupling element mating with the first one and associated with the housing.
  • Yet another aspect of the invention is represented by an interchangeable cartridge for use in the aforementioned olfactory device, the cartridge containing an olfactive substance and having a first bayonet coupling element adapted to couple with a second bayonet coupling element provided in a seat of the olfactory device.

  • the corresponding female element, in the seat 35 is represented by two slots 351. If correctly aligned, the small bottle 50 can be inserted into the seat 35 by passing the fins 502 through the slots 351.
  • the fins 502 can also be used for fixing the cap 51 of the small bottle. Therefore, the cap of the small bottle can also have a bayonet-type clamping. For this reason, the cap can also comprise a suitable female seat adapted to house the fins 502.
  • Fig. 10 the reference numerals indicate details corresponding to those already described with reference to Fig. 2.
