Abstract
Description
[Technical field]
[0001] The present invention relates generally to volatile substance devices, and more particularly to methods of enhancing fragrance delivery devices, their uses, and related products and services. [Background technology]
[0002] Volatile fragrance manufacturers have long sought to make sample fragrances available to customers and / or consumers to encourage purchases. Volatile fragrances, such as consumer fine fragrances, are advertised in multiple types of media and are typically sold at the sales counter of a retail store. While brand name recognition is important to fragrance consumers, so is the actual smell of the fragrance. Often, fragrance consumers will want to try new and / or unfamiliar fragrances before purchasing a large quantity of the fragrance.
[0003] One device used to economically dispense fragrance samples is the sample atomizer. Atomizers are used in point-of-sale displays to spray measured amounts of fragrance into the air or onto the customer's hand or wrist. One drawback of atomizers is that they are difficult to use when spraying into the air to obtain good scent samples. However, when spraying onto the customer's hand or wrist, the number of different scent samples that can be made is effectively limited to two, one on each hand or wrist.
[0004] Of course, unscented paper card stock or blotters, such as those used by perfume scientists, can be used as a substrate to apply and absorb the volatile fragrance. The user can then smell the volatile fragrance emanating from the sprayed blotter. However, as the volatile fragrance gradually evaporates, the scent loses intensity and therefore its shelf life. Furthermore, when sampling multiple fragrances, it is easy to forget which volatile fragrance was applied to which blotter, unless the user manually records the information on the blotter or affixes a label to the blotter detailing each volatile fragrance.
[0005] Other common devices for sampling fragrances include so-called "peel and sniff" or "scratch and sniff" cards, as described in US Pat. No. 5,399,623 or US Pat. No. 5,499,636. These fragrance-containing sample cards are often distributed in magazines or by mail. The basic idea of a peel and sniff or scratch and sniff card is to adhere (e.g., using a lacquer or adhesive) an absorbed fragrance (e.g., on talc) or an encapsulated volatile fragrance (e.g., gelatin or plastic microspheres) to the card surface. Typically, the sample card has a reversibly removable water-blocking layer that covers the scented area. When the scented area of the card is uncovered, scratched, and / or pressed, the volatilized fragrance is exposed and can be smelled. These cards are often printed with indicia relating to details about the fragrance, e.g. brand name, manufacturer, composition, etc., however the adhesives used in this technology often prevent an accurate reproduction of the "real" scent of the perfume product and / or may deteriorate over time.
[0006] Of course, other types of fragrance delivery devices are known. For example, US Pat. No. 5,399,433, assigned to SAS Carestia, describes a rectangular plate with two outer walls that sandwich an inner plate and one or more typical capsules. The inner plate is made in the form of an open cell foam plastic, in the form of a nonwoven fabric, or in a structure that has the effect of slowing down the time it takes for the volatile material to migrate from the capsule to the permeable outer wall. The outer wall is reported to be permeable to the fragrance, but the reported construction material is paper or cardboard with a basis weight in the range of a typical business card or invitation. No details of the capsules (e.g. shell, fragrance, solvent, textural properties, etc.) are given.
[0007] Another odorant or freshener article described in U.S. Patent No. 5,393,333 assigned to R.J. Reynolds Tobacco Company includes embedding or infusing a fragrance into a web or filament tow material in liquid or powder form, or in the form of frangible fragrance-containing capsules, and may further include an antistatic additive for use in clothes dryers. Again, details of the capsules (e.g., shell, fragrance, solvent, textural characteristics, etc.) are not described.
[0008] Thus, new devices and methods for sampling and / or marketing volatile fragrances are needed to overcome one or more deficiencies of conventional approaches. [Prior art documents] [Patent documents]

[0011] Certain aspects of the present disclosure are set forth in the appended claims. The subject matter described herein has additional features and advantages. They will become apparent as the present specification proceeds. The various features of the claims and the various embodiments described below can be used in combination or separately. For example, a specified range can include its stated end point unless expressly excluded. Any particular embodiment does not need to provide all of the features described above, nor does it need to solve all of the problems or address all of the problems described above.
[0012] According to an embodiment of the present invention, there is provided a fragrance delivery device comprising, consisting essentially of, or consisting of a plurality of fragrance-filled capsules, an absorbent medium disposed adjacent to the fragrance-filled capsules in both directions along an axial direction, and an outer paper cover surrounding and containing the fragrance-filled capsules and the absorbent medium. The outer paper cover allows the fragrance compound to diffuse through the outer paper cover and also includes a user-visible printed indicia, for example including or consisting of a one-dimensional or two-dimensional barcode. The fragrance-filled capsule is a seamless capsule including (consisting essentially of, or consisting of) a capsule shell surrounding a liquid core including the fragrance compound and a non-glyceride solvent, the liquid core having a relative density between 0.85 and 0.99. The capsule shell of the seamless capsule includes a hydrocolloid mixture, and the shell has an initial breaking strength (C i The capsule shell is a frangible shell having a pressure of 0.5-2.5 kg, an elasticity of up to 60%, and a shape ratio of 0.9 or greater. Upon application of sufficient frangible force to rupture the capsule shell, the adjacent absorbent medium absorbs the liquid core, thereby gradually transporting the fragrance compound toward the outer paper cover and then diffusing into the adjacent surroundings. Surprisingly, it has been found that fragrance delivery devices including the fragrance-filled capsules described herein provide users with a longer-lasting sensory experience with greater fidelity of top, middle, and bottom notes compared to conventional blotters.
[0013] According to one embodiment of the present invention, the fragrance delivery device is combined with a remote server to further provide a fragrance delivery system that allows a user to utilize the portable electronic device to obtain information about the fragrance-filled capsules when the portable electronic device detects indicia, such as a 1D or 2D barcode, printed on the surface of the outer paper cover. The fragrance delivery system also allows for two-way information exchange, where end users can register accounts and provide feedback about the fragrance delivery device.
[0014] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and, together with the general description of the invention given above and the detailed description given below, serve to explain the invention. It will be understood that reference numerals have been repeated in the drawings for clarity and where considered appropriate to indicate corresponding features. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Unless otherwise explained, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. In case of conflict, the present specification, including explanations of terms, will control. The singular terms "a," "an," "at least one," and "the" include plural referents unless the context clearly indicates otherwise. Similarly, the word "or" is intended to include "and" unless the context clearly indicates otherwise. The term "comprising" means "including." Thus, "comprising A or B" means including A or B and including A and B together.
[0017] 1 is a plan view of a fragrance delivery device 10 comprising a plurality of fragrance-filled capsules 12 (shown in dashed lines) and an outer paper cover 16 that surrounds and contains the fragrance-filled capsules 12. The outer paper cover 16 includes printed indicia 18 and capsule location markings 20 that are visible to an observer. These visible features allow an observer to obtain information regarding the fragrance-filled capsules 12, as well as the location of each capsule beneath the outer paper cover 16, as will be described further herein.
[0018] FIG. 2 is a cross-sectional view along dashed line 1A-1A of the fragrance delivery device shown in FIG. 1, illustrating a first embodiment in which the absorbent medium 14 is arranged in a continuous configuration in both directions along the axial direction adjacent to the fragrance-filled capsule 12.
[0019] FIG. 3 is a cross-sectional view along dashed line 1A-1A of the fragrance delivery device shown in FIG. 1, showing a second embodiment in which individual portions of absorbent medium 14 having length c are positioned adjacent to the fragrance-filled capsule 12 in both axial directions.
[0020] 1-3, the fragrance-filled capsule 12 comprises a capsule shell 22 enclosing a liquid core 24 containing a fragrance compound and optionally a solvent.
[0021] According to an embodiment of the present invention, the term "capsule" refers to a core-shell structure in which the capsule shell 22 surrounds a liquid core 24, as distinguished from a matrix system in which small droplets of liquid are dispersed within a continuous matrix of shell-forming material. According to an embodiment of the present invention, the fragrance-filled capsule 12 is seamless, eliminating the need to weld two half shells together, as is the case with so-called "soft gel" capsules. The seamless fragrance-filled capsule 12 therefore has the advantage that leakage associated with the rupture of weak welds can be avoided.
[0022] According to an embodiment of the present invention, the term "fragile capsule" refers to a capsule whose shell can be broken by applying a force to opposing sides of the capsule's exterior, as defined above. Upon application of sufficient breaking force to rupture the capsule shell 22, the liquid core 24 is absorbed into the adjacent absorbent medium 14, thereby causing the fragrance compound to gradually diffuse towards the outer paper cover 16 and then into the adjacent surroundings. The frangible capsule according to the present invention has a hardness (initial breaking strength (C)) between 0.5 and 2.5 kg. i ) and thus can be broken by applying a force between two fingers, making an audible noise upon breaking.
[0023] The capsule shell 22 according to the invention advantageously comprises at least one hydrocolloid gelling agent. Preferably, the hydrocolloid gelling agent is a bio-based polymer. By "bio-based" is meant a synthetic polymer at least partially (generally more than 20%) or entirely derived from biomass or its derivatives. The bio-based nature of a polymer can in particular be determined from its C14 content according to the ASTM D6866-21 standard.
[0024] The hydrocolloid gelling agent of the capsule shell 22 of the fragrance filled capsule 12 is preferably selected from the group consisting of gellan gum, gelatin (of animal or biotechnological origin), collagen, alginate, carrageenan, agar, chitosan and its derivatives, pectin, gum arabic, gum ghatti, pullulan gum, mannan gum, starch and starch derivatives, vegetable proteins, or modified cellulose, and combinations thereof. To prepare a seamless capsule that is not of animal origin, the shell material of the breakable capsule should be free of any gelatin of animal origin.
[0025] In a preferred embodiment, the hydrocolloid gelling agent comprises gellan gum, used alone or in combination with gelatin. In another preferred embodiment, the hydrocolloid gelling agent comprises carrageenan. Based on the total mass of the dry weight ingredients in the shell, the hydrocolloid gelling agent is present in an amount ranging from about 10% to about 95% by weight, preferably 15% to 75% by weight, more preferably 20% to 50% by weight.
[0026] The shell material further comprises a filler. Exemplary fillers include, but are not limited to, starch derivatives such as dextrin, maltodextrin, inulin, sucrose, allulose, tagatose, cyclodextrin (alpha, beta, gamma, or modified cyclodextrin), cellulose derivatives such as microcrystalline cellulose (MCC), hydroxypropyl cellulose (HPC), hydroxypropylmethylcellulose (HPMC), methylcellulose (MC), or carboxymethylcellulose (CMC), polyvinyl alcohol, nonplastic polyols, trehalose, erythritol, maltitol, mannitol, xylitol, sorbitol, glycerol, triacetin, polyethylene glycol, plasticizing or moisturizing polyalcohols, or combinations of two or more of the foregoing. Based on the total mass of the dry weight ingredients in the shell, the filler can be present in an amount ranging from about 10% to about 90% by weight, preferably 15% to 75% by weight, and more preferably 20% to 50% by weight.
[0027] As further described below, the seamless fragrance-filled capsule 12 is formed by co-extrusion, whereby a gellable aqueous mixture of dry ingredients (e.g., hydrocolloid gelling agent, fillers, and other additives) is formed by mixing with water. Typical weight ratios of water to non-aqueous (dry) ingredients range from 1:1 to 20:1. Preferably, the water used in the external phase is purified water, such as distilled water, deionized water, or reverse osmosis water, although treated water is viable. The gellable aqueous mixture may further include crosslinkers, colorants, sequestering agents, and the like.
[0028] The liquid core 24 comprises at least one perfume formulation / fragrance compound and at least one non-glyceride lipophilic solvent. Advantageously, the non-glyceride solvent is miscible with ethanol and has the following properties: a) at a temperature of 25° C. and at least 10 s -1 a) has a viscosity of less than 10 mPa sec when measured at a shear rate of 850 mm 2 / 10 minutes; and c) have a relative density between 0.85 and 0.99.
[0029] An important technical advantage of the present invention is that the non-glyceride lipophilic solvent allows for the encapsulation of the liquid core using co-extrusion techniques to obtain a frangible and stable capsule, which further provides good transport of the perfume composition (by absorption into the adjacent absorbent medium 14) to the outer paper cover 16.
[0030] In fact, those skilled in the art of perfumery know that in conventional perfume compositions, the presence of a large amount of ethanol "carries" the perfume molecules, allowing the perfume to evaporate, thus providing the fragrance effect. However, co-extrusion encapsulation of liquid core compositions containing a large amount of ethanol is not feasible because ethanol is hydrophilic and destabilizes the interface between the liquid core and the aqueous shell-forming composition. If ethanol is simply replaced with a conventional lipophilic co-extrusion solvent, such as medium chain triglyceride (MCT), co-extrusion is likely to be successful, but MCT not only significantly limits the diffusion of perfume molecules, but may also leave a greasy feeling on the skin or oily stains on clothing.
[0031] Advantageously, the non-glyceride lipophilic solvent is miscible with both the ethanol and the perfume formulation, and furthermore does not have an odor that interferes with the aroma of the perfume composition. As used herein, the term "miscible" is understood to mean that the non-glyceride lipophilic solvent can be mixed with the perfume and ethanol to form a homogenous mixture. In some cases, depending on the degree of lipophilicity of the perfume, it is advantageous to use a small amount of ethanol (e.g., 0-10% by weight) in the liquid core composition during the co-extrusion process, most of which evaporates during drying of the capsule. Similarly, a small amount of glyceride solvent is also acceptable. However, the non-glyceride lipophilic solvent used in the embodiments of the present invention is the major solvent, i.e., more than 50% by weight.
[0032] Thus, the non-glyceride hydrophilic solvent defined in accordance with the present invention provides the following advantages to the liquid core 24: a) stable liquid core formulation, b) good transportability for transporting the perfume formulation through the absorbent medium 14 to the outer paper cover 16, c) good evaporation profile of the perfume composition through the outer paper cover 16, d) no sticky or oily feeling, and e) no staining of clothing materials.
[0033] In one embodiment, the non-glyceride lipophilic solvent is selected from the group consisting of non-glycerol esters (e.g., isopropyl myristate, isoadipate, and / or cococaprylate), silicones (e.g., polydimethylsiloxane, octamethyltrisiloxane, and / or dimethicone), vegetable oils (e.g., grapeseed oil), and combinations thereof. In one embodiment, vegetable oils are preferred to obtain a bio-based and biodegradable capsule. In another embodiment, the non-glyceride lipophilic solvent is selected from the group consisting of isopropyl myristate, isoadipate, cococaprylate, polydimethylsiloxane, octamethyltrisiloxane, dimethicone, and grapeseed oil, and combinations thereof.
[0034] The relative density of the non-glyceride lipophilic solvent is preferably between 0.85 and 0.99. By definition, the relative density of a composition corresponds to the ratio of the density of said composition measured at 20°C to the density of water at 4°C. This range of relative densities of the non-glyceride lipophilic solvent ensures good results during the manufacture of capsules by the so-called co-extrusion process. Advantageously, the relative density of the total composition of the liquid core (e.g., flavor formulation, lipophilic solvent, ethanol if present) is between 0.85 and 0.99.
[0035] Advantageously, the non-glyceride lipophilic solvent is dissolved at a temperature of 25° C. and for 10 s. -1 Viscosity (η) measurements, expressed in mPa·sec, were performed using a Haake MARS III rheometer at 25°C, using a 5 mm cone with a 2 degree angle, at a shear rate of 10 sec -1 It is held.
[0036] Non-glyceride lipophilic solvents are 850mm 2The diffusion value (or diffusivity) of any substance is generally defined as the ability of said substance to cover a surface in a certain time. Advantageously, the diffusion value of lipophilic solvents (chosen from esters, silicones, vegetable oils and mineral oils) can be calculated at 10-minute intervals using the equations cited from "Esters, Silicones, Vegetable Oils and Mineral Oils" (2003). In fact, after statistical analysis by partial least squares regression, the viscosity (x) measured at 25°C was found to be the most reliable variable for predicting the diffusion value (y) as a function of the nature of the non-glyceride lipophilic solvent, according to various chemical-specific logarithmic regressions: for esters: y=-255xlog(x)+1315, for silicones: y=-222xlog(x)+1670, for vegetable oils: y=-101xlog(x)+748. These equations can be used for screening or selecting non-glyceride lipophilic solvents.
[0037] According to an embodiment of the present invention, the non-glyceride lipophilic solvent is between 10% and 99.99% by weight based on the total weight of the liquid core composition. A small amount of ethanol (e.g., between 0 and 10% by weight based on the total weight of the liquid core composition) and / or a small amount of a glyceride solvent (e.g., between 0 and 5% by weight based on the total weight of the liquid core composition) can be used together with the non-glyceride lipophilic solvent. For example, the non-glyceride lipophilic solvent can be present in the liquid core at between 15% and 90% by weight, or between 20% and 80% by weight, or between 25% and 75% by weight based on the total weight of the liquid core composition.
[0038] Exemplary perfume formulations / fragrance compounds useful in the liquid core 24 of the fragrance-filled capsule include, but are not limited to, one or more aromatic or fragrance molecules as conventionally used in the formulation of flavor or fragrance compositions. For example, fragrance molecules include aromatic, terpene and / or sesquiterpene hydrocarbons, more specifically, essential oils, alcohols, aldehydes, ketones, phenols, various forms of carboxylic acids, aromatic acetals and ethers, nitrogen heterocycles, sulfides, disulfides, and mercaptans, which may be aromatic or non-aromatic. Such odorants are described, for example, in "Fragrances of the Odorless" by John Wiley & Sons, Inc., 1999, pp. 111-114, 2002, or "Fragrances of the Odorless" by John Wiley & Sons, Inc., 1999, pp. 111-114, 2002, and ... The perfume formulation may also include one or more captive agents, including, but not limited to, Orcanox® 1,5,5,9-tetramethyl-13-oxatricyclo[8.3.0.0]tridecane, Betahydrane® (3-benzyl-tetrahydropyran), Antillone® (9-decen-2-one), Noreenal® ((±)-6,8-dimethylnon-7-enal), and / or Pescagreen® (2-(2,4,4-trimethyl-cyclopentyl)-acrylonitrile). In one embodiment, the perfume formulation in the liquid core is between 0.01% and 90% by weight, based on the total weight of the liquid core composition. For example, based on the total weight of the liquid core composition, the perfume formulation may be present in the liquid core in an amount of 1% to 85% by weight, or 5% to 80% by weight, or 10% to 75% by weight.
[0039] According to one embodiment, the amount of fragrance formulation in the liquid core may be defined based on the end use, e.g., aromatherapy, fragrance sampling, air freshening, etc. Additionally, the diameter of the dried fragrance-filled capsule 12 and / or the thickness of the capsule shell may be adjusted to achieve a desired volume of liquid core for a particular end use.
[0040] Advantageously, fragrance formulations and other ingredients can be rated for their environmental impact using MANE's GREEN MOTION® Index. The index rates the health, safety, and environmental impact of raw materials produced in the flavor and fragrance industry on a scale of 0-100. The safer and less impactful the process, the higher the rating. The GREEN MOTION™ Index is essentially tied to the 12 principles of green chemistry proposed by Anastas and Warner (4). However, GREEN MOTION® focuses on seven basic concepts: hazards and toxicity of raw materials, solvents, and reagents, hazards and toxicity of reactions, processes, and final products, and waste.
[0041] In addition to the perfume formulation and the non-glyceride lipophilic solvent, the liquid core 24 of the fragrance-filled capsule 12 can advantageously include a fixative in the formulation to inhibit the rapid evaporation of the perfume formulation and provide a longer-lasting scent. Fixatives are less volatile than the perfume formulation itself and therefore reduce the rate of evaporation of the fragrance ingredients. Non-limiting types of suitable fixatives include absolutes, concretes, resins, derivatives of glucose, sucrose, sorbitol, citric acid, and salicylic acid, cellulose (especially ethyl cellulose), seaweed extracts, triglycerides, oils such as castor oil and its derivatives, emollients such as certain esters such as ethylhexylglycerin, polyurethanes, polyamides, certain silicones, liquid paraffins, glycol ethers, pyrogenic silica, and quaternary ammonium salts.
[0042] According to a preferred embodiment of the present invention, the liquid core 24 of the fragrance-filled capsule 12 represents 50% to 95% (w / w), preferably 80% to 92%, more preferably 85% to 92% of said capsule. Conversely, in this preferred embodiment, the capsule shell 22 of the fragrance-filled capsule 12 represents 5% to 50% (w / w), preferably 8% to 20%, more preferably 8% to 15% of said capsule.
[0043] Seamless fragrance-filled capsules 12 can be produced by a co-extrusion process, as described in US Pat. No. 5,399,363. A general procedure for preparing seamless capsules is described below. The outer phase of a gellable aqueous mixture of dry ingredients (e.g., hydrocolloid gelling agents, fillers, and other additives) and the inner oil phase of a liquid core are pumped through a separately immersed coaxial nozzle assembly to form a concentric composite stream, which separates into separate concentric droplets under the influence of applied vibrational energy. The discharge from the coaxial nozzle is immersed in a carrier fluid (e.g., medium chain triglycerides (MCT)) at a temperature lower than the gelling temperature of the gellable aqueous mixture. The gellable aqueous mixture is thus cooled to form the hydrated hydrocolloid-containing shell portion of the capsule. The capsules thus formed are then collected and centrifuged to remove most of the residual MCT. The centrifuged capsules are further treated with a desiccant or drying agent (e.g., starch or silica) and subsequently dried in air at 30-45°C. The resulting dry capsules are then collected and sieved. The dry fragrance-filled capsules 12 prepared according to the embodiments of the present invention have a homogenous and smooth appearance and are spherical or substantially spherical (measured by the average ratio of the width to the length of the microcapsule). In a preferred embodiment, the dry seamless fragrance-filled capsules 12 have textural properties (e.g., initial breaking strength or elasticity) that allow them to withstand further manipulation and incorporation into a fragrance delivery device, but can be broken by the force of squeezing between two fingers (with an audible pop upon breaking).
[0044] Advantageously, the outer diameter of the dry fragrance-filled capsule 12 is between 2 and 10 mm, preferably between 3 and 5 mm, more preferably between 3.4 and 4.8 mm, and even more preferably between 3.5 and 4.5 mm. The thickness of the shell 22 of the fragrance-filled capsule 12 is between 10 and 500 microns, preferably between 30 and 150 microns, and more preferably between 50 and 80 microns, and the capsule diameter / shell thickness ratio is in the range of 10 to 100, preferably in the range of 50 to 70. The dry fragrance-filled seamless capsule 12 has an initial breaking strength (Ci ) is 0.5-2.5 kg, elasticity is up to 60%, and shape ratio is 0.9 or more. For the purpose of determining the above characteristics, the moisture content of the dried capsules (measured by Karl Fischer titration) is less than 5% by weight, based on the total weight of the capsule.
[0045] Initial capsule breaking strength (C i ) (also called hardness or force at break) is measured using a TA.XTplus texture analyzer from Stable Micro System Ltd. (Surrey, UK) in compression mode with a 5Kg load cell. Probe: P0.5-1 / 2 diameter DELRIN® cylinder, cylinder speed 0.5mm / sec, resolution 0.01Kg, taking an average of 20 capsules. The capsules are placed between the base of the TA.XT plus device and the probe. A vertical compressive force is then applied continuously to one particle until the frangible shell ruptures, while a built-in gauge simultaneously records the force (in kilograms (Kg)) and position (in millimeters (mm)). The capsule ruptures, accompanied by an audible noise indicating the rupture and release of the liquid core.
[0046] "Deformation" is the ratio of the distance at break to the initial size of the capsule, and "distance at break" (mm) is the distance covered by the probe from contact with the capsule to the point of capsule breakage, measured using the TA.XTplus texture analyzer as described above. "Elasticity" is the deformation value expressed in percentage.
[0047] The shape ratio (or symmetry) of the dry capsules is ≥ 0.9. The equivalent diameter and symmetry / shape ratio are measured by a CPA2-1 from Haver&Boecker. The CPA is a photographic optical unit for measuring the size and shape analysis of dry particles (e.g. capsules). The CPA unit consists of a feeding unit, an optical sensor, a camera, a special light source, and an electronic module. The capsules are dropped in front of the camera. The shadow projection is detected by the camera and evaluated in real time in the CPA Serv software.
[0048] The fragrance-filled capsules 12 are embedded in an axially disposed absorbent medium 14 that is surrounded and retained by an outer paper cover 16. The diffusivity of the fragrance can be enhanced by modifying certain properties of the absorbent medium 14 (such as chemical composition, density, pressure drop, hardness, shape, and diameter) and / or by modifying certain properties of the outer paper cover 16 (such as coating, perforation, weight, and porosity).
[0049] As shown in Figure 2, the absorbent medium 14 may have a continuous configuration with a cavity for accommodating a substantially spherical or spherical fragrance-filled capsule 12. Alternatively, the absorbent medium 14 may be in discrete portions, as shown in Figure 3. Although not shown, the absorbent medium 14 may be configured with radially extending or axially extending channels to enhance the absorption and / or diffusion rate of the fragrance.
[0050] According to one embodiment of the present invention, the absorbent medium 14 comprises a biodegradable / biodegradable polymer. As used herein, a "biodegradable" material means a material that can be rapidly decomposed under natural conditions within one year using standard test methods (ISO14855-2:2018), where biodegradation is the process by which organic materials are broken down by microorganisms (mainly aerobic bacteria) into simpler substances such as carbon dioxide, water and ammonia.
[0051] Conventional cigarette filters are made of cellulose acetate, a chemically modified natural polymer. While acetylation of cellulose's hydroxyl groups confers favorable and useful properties, this hydrophobized form also inhibits cellulose's ability to biodegrade. Thus, cellulose acetate is not considered to be biodegradable unless it is combined with other components or materials that promote deacetylation, such as the "biodegradation promoters" described in U.S. Pat. No. 6,399,431, or materials that catalyze the hydrolysis of cellulose acetate filaments, as described in U.S. Pat. No. 6,399,431.
[0052] Non-limiting examples of biodegradable absorbent media materials include cellulose, flax, cotton, abaca, polylactic acid or polylactide, and biodegradable polyesters (e.g., polyglycolic acid, polylactic acid, polyhydroxyalkanoates, polycaprolactone, polybutylene succinate adipate, and copolymers or blends thereof) as described in US Pat. No. 5,399,363, assigned to RJ Reynolds and incorporated herein by reference in its entirety. Non-limiting examples of commercially available bio-based and biodegradable absorbent media materials include Eastman ESTRON® (Kingsport, Tennessee), biodegradable tow from Tianjin NAT Technology (Tianjin, China), Greenbutts® from Greenbutts LLC (San Diego, California), Cerdia® DE-Tow from Cerdia International GMBH (Basel, Switzerland), or ECO Active® from Essentra Filter Products Development Co. Pte. Ltd (Singapore).
[0053] In one embodiment, the absorbent medium 14 material may include randomly oriented regenerated cellulose and cellulose acetate fibers and may further include a binder. As used herein, the term "regenerated cellulose fibers" refers to cellulose fibers formed by processing natural cellulose materials to provide cellulose fibers with desired physical properties. A typical process for forming regenerated cellulose fibers includes pulping natural cellulose materials, such as wood chips, to form a pulp, subjecting the pulp to one or more treatment steps to modify the physical properties of the cellulose, and forming regenerated cellulose fibers from the treated pulp, for example, by passing the pulp through a triangular spinneret to spin the cellulose fibers and provide a Y-shaped cross section.
[0054] According to one embodiment of the present invention, the absorbent medium material is characterized by a denier filament in the range of 2.5Y-8.0Y and a total linear density of 10000-40000. Denier filament is weight in units of length and is defined as the weight in grams of 9000m of linear cellulosic material. Denier is a direct metric measure, with smaller numbers indicating finer dimensions and larger numbers indicating thicker dimensions. A single filament of 9000m length and weighing 1 gram is equal to denier 1. Total denier is the weight in grams of a 9000m length of absorbent material fiber. Absorbent medium materials can be characterized by their denier filament and total denier. For example, a 6.0Y17000 absorbent material has a denier per filament (or filament denier) of 6.0 and a total denier of 17000, with a cross section Y that is commonly used in the tobacco industry. In one embodiment, the absorbent medium material has a filament denier of 4.0-8.0 and a total linear density of 12,000-30,000.
[0055] Advantageously, the use of an absorbent material comprising randomly oriented regenerated cellulose improves degradation of the filtration media, as the randomly oriented fibers are more easily dispersed after the fragrance delivery device 10 is discarded, especially when compared to the substantially continuous filaments of conventional cellulose acetate tow materials. Increasing fiber dispersion increases the exposure of individual fibers to the environment, thus increasing the rate of degradation of the cellulose material.
[0056] Cellulose and its derivatives, including those used in more traditional paper applications, are preferably sourced responsibly. Exemplary environmental certifications such as FSC (Forest Stewardship Council) or PEFC (Programme for the Endorsement of Forest Certification) are well-known certifications to ensure traceability of the source of pulp. European Standard EN643 "European List of Standard Grades of Recycled Paper and Recycled Cardboard" defines paper and cardboard materials and products that can be recovered through recycling. According to one embodiment, the absorbent material is manufactured from responsibly sourced or recycled cellulosic materials.
[0057] According to one aspect of the present invention, the absorbent media material is formed into a substantially cylindrical or cylindrical shape using a binder composition. One common binder material is triacetin. In one embodiment, the binder composition may further include one or more of dimethyl isosorbide, propylene carbonate, methyl benzyl alcohol, glycerol carbonate acetate, glycerol carbonate ethyl ether, and mixtures thereof. In another embodiment, the binder composition does not include any of dimethyl isosorbide, propylene carbonate, methyl benzyl alcohol, glycerol, and glycerol derivatives such as glycerol carbonate acetate or glycerol carbonate ethyl ether, or mixtures thereof.
[0058] The triacetin or triacetin-containing binder composition is preferably present in an amount of from about 1% to about 15% by weight of the absorbent medium, more preferably from about 5% to about 13% by weight of the absorbent medium, and most preferably from about 8% to about 12% by weight of the absorbent medium.
[0059] The fragrance-filled capsule 12 and absorbent medium 14 are surrounded and held by an outer paper cover 16. Like the absorbent medium 14, the outer paper cover 16 is also biodegradable. Suitable materials for constructing the outer paper cover include, but are not limited to, cellulose and its derivatives, with or without fillers. In one embodiment, the outer paper cover 16 is non-porous. The porosity of the outer paper cover 16 is expressed in CORESTA Units (CU) and is the porosity of the outer paper cover 16 at 1 cm under a pressure difference of 1 kPa. 2 The volumetric flow rate (cm) of air passing through the substrate sample 3 / min). In one embodiment, the porosity of the outer paper cover is less than 5 CU, such as 4 CU, 3 CU, 2 CU, 1 CU, or 0 CU, or within a range between any two of the aforementioned values.
[0060] In one embodiment, the outer paper cover 16 is coated or impregnated. Coating or impregnation can be performed utilizing a blade coater, roll coater, dipping roll, curtain coater, size press, or other conventional coating and impregnation methods. Non-limiting examples of commercially available bio-based and biodegradable outer paper covers 16 include plug wrapper manufactured by Delfort Group (Traun, Austria) or plug wrapper manufactured by Schweitzer-Mauduit International, Inc. (Alpharetta, Georgia).
[0061] Basis weight or grams is a fundamental property of the outer paper cover 16. The basis weight of a paper is its weight per unit area. It is expressed in grams per square meter (gsm or g / M 2 ) according to one embodiment, the gram weight of the outer paper cover 16 can vary from 22 gsm to 90 gsm, which provides good diffusion of the fragrance, good feel of the device, and rigidity of the fragrance delivery device 10, while still inhibiting migration of solvent / oils to the user's fingers and maintaining the relative cylindrical shape of the device during use. For example, the gram weight of the outer paper cover 16 can be 22-90 gsm, 24-80 gsm, 26-70 gsm, or 30-60 gsm.
[0062] As shown in Figure 1, in accordance with an embodiment of the present invention, the outer paper cover 16 has printed indicia 18 and position markings 20 printed on its surface. Printing may be performed after assembly, but it is preferred to print the outer paper cover 16 while the paper is flat, prior to assembly. Printing (which may be colored) on the flat outer paper cover 16 allows the indicia and markings to be printed with an accuracy of + / - 2mm. The capsule position markings 20 allow for easy and quick identification of the location of the fragrance-filled seamless capsules.
[0063] As shown in FIG. 4, the printed indicia 18 may provide information directly identifiable to the user, such as a company name, brand name, trademark, or any other information related to the fragrance composition within the device. Advantageously, the printed indicia 18 includes a scannable one- or two-dimensional barcode (e.g., Code 39, Code 128, QR, UPC-A, EAN-8, EAN-13, and ITF barcode) or any other smartphone scannable code that can be photographed / detected by the portable electronic device 38, allowing the consumer to instantly and directly link to a specific internet URL site on the remote server 40. Thus, the printed indicia 18 allows the user to use the portable electronic device to obtain information about the fragrance-filled seamless capsule. For example, the user may have direct access to information about the fragrance, such as the fragrance composition, origin of the ingredients, supplier information, the GREEN MOTION® index, and other details related to the user, such as ratings and comments from other users and perfumers.
[0064] The remote server 40 may also be configured to allow two-way information exchange, whereby an end user may register or create an account and provide feedback or evaluation regarding the fragrance delivery device 10 and the contents of the fragrance-filled capsule 12. Thus, the remote server 40 is linked to the fragrance delivery device 10 via the printed indicia 18, and upon detection, decoding, and / or transmission of the printed indicia 18 by a visual detection application residing on the portable electronic device 38 to the remote server 40, information regarding the fragrance delivery device 10 is transmitted to the portable electronic device 38 and displayed. Additionally, a user-created file or account may be utilized to store personal information about the user, including the quantity and / or type of fragrance composition sampled, and also serves as a record of the user's likes and dislikes. The user-created file may be stored on the portable electronic device 38 and / or on the remote server 40.
[0065] Thus, in one embodiment of the present invention, a fragrance delivery system is provided, comprising, consisting essentially of or consisting of a fragrance delivery device 10 and a remote server 40 linked to a printed indicia 18, said remote server 40 adapted to transmit and display information about the fragrance delivery device 10 to / on the portable electronic device 38 upon detection, decoding and / or transmission of the printed indicia 18, such as, for example, a one-dimensional or two-dimensional barcode, by a visual detection application belonging to the portable electronic device 38. Furthermore, the user of the portable electronic device 38 and the fragrance delivery device 10 may be provided with a file for storing personal or product-related information, said file being stored on the portable electronic device 38 or on the remote server 40.
[0066] Based on the substantially spherical or globular shape of the fragrance-filled seamless capsule and the known technology of manufacturing cigarette filters with flavor-filled capsules, the fragrance delivery device of the present invention can be manufactured using conventional cigarette and capsule packaging machines. This assembly of the substantially spherical or globular fragrance-filled capsule 12, the absorbent medium 14, and the outer paper cover 16 may further include the use of an adhesive to secure the fragrance-filled capsule 12 and / or the absorbent medium 14 to the outer paper cover 16 and to bond the seams of the outer paper cover 16. Suitable biodegradable adhesives for securing the fragrance-filled capsule 12 and / or the absorbent medium 14 and to bond the seams of the outer paper cover 16 include, for example, polyvinyl acetate (PVA) or biodegradable hot melt (HM) adhesives.
[0067] The adhesion of the absorbent medium 14 to the outer paper cover 16, together with the physical properties of the absorbent medium 14 to the outer paper cover 16 itself, provides good structural integrity to the fragrance delivery device 10. For example, the Borgwald hardness, which represents the remaining height of the diameter of the fragrance delivery device relative to its original diameter after a test with a load of 2 kg and a set time of 10 seconds, can be used to characterize the fragrance delivery device 10. The Borgwald hardness test is performed using a Borgwald DD60A density meter (manufactured and commercially available by Heinr. Borgwaldt GmbH, Germany). According to an embodiment of the present invention, the fragrance delivery device 10 has a Borgwald hardness of 50% or more, preferably 75% or more, and more preferably 80% or more.
[0068] According to an embodiment of the present invention, and further referring to Figures 1-3, the fragrance delivery device 10 is comprised of a cylindrical body including a distal end 30 and a proximal end 32, and a plurality of seamless fragrance-filled capsules 12 aligned axially along the central axis of the cylindrical body, the plurality of capsules being spaced and separated by portions of an absorbing medium 14. The length and diameter dimensions are not limited with respect to the implementation of the fragrance delivery device 10. The length (L1) of the cylindrical body can be in the range of about 5 cm to about 25 cm, preferably in the range of about 10 cm to about 20 cm, and the diameter (D1) of the cylindrical body can be, for example, in the range of about 4 mm to about 15 mm, preferably in the range of about 5 mm to about 10 mm.
[0069] In one embodiment, the diameter (D1) of the fragrance delivery device 10 is related to the capsule diameter (a), and the diameter (D1) of the fragrance delivery device 10 is larger than the diameter (a) of the fragrance-filled capsule 12. As shown in Figure 2, the fragrance-filled capsule 12 having a diameter (a) is housed within the fragrance delivery device 10 having an overall diameter (D1), but is preferably not in contact with the outer paper cover 16 and is spaced apart by a distance (b), thereby minimizing damage to the fragrance-filled capsule 12 during assembly of the fragrance delivery device 10.
[0070] Additional modifications and features can be added to enhance the sensory experience of using the fragrance delivery device described herein. For example, as shown in the embodiment depicted in FIG. 1, small perforations 36 can be strategically placed in the outer paper cover 16 to enhance the diffusion of the fragrance immediately after the capsule is broken without undue exposure of the user to liquid leakage. Although not shown, the absorbent medium 14 may be provided with axial or radial channels to facilitate diffusion of the fragrance compounds towards the external environment. In another embodiment, the outer paper cover 16 of the fragrance delivery device 10 is not provided with perforations.
[0071] The dried, frangible fragrance-filled capsule 12 is combined with an absorbent medium 14 and wrapped in an outer paper cover 16 to form the fragrance delivery device 10, and the absorbent medium 14 is secured to the outer paper cover 16 using one or two strips of adhesive (e.g., hot melt adhesive or polyvinyl alcohol adhesive) and the seam of the outer paper cover 16 is glued using one adhesive line to form a single exterior surface of the device 10. The fragrance delivery device 10 can be manufactured using standard or modified cigarette filter manufacturing machines equipped with a capsule inserter. For example, machines manufactured by ITM Group (e.g., ITM Poland or ITM Solaris) or Hauni Group (e.g., FLEXPORT CI module) can be used to prepare the fragrance delivery device 10 described herein.
[0072] According to yet another embodiment of the present invention, a method of using the fragrance delivery device 10 is provided. The method includes providing the fragrance delivery device 10 to a person, detecting, decoding and / or transmitting a two-dimensional barcode to a remote server 40 by a visual detection application residing on a portable electronic device 38, transmitting information about the fragrance delivery device 10 from the remote server 38 and receiving said information at the portable electronic device 38, and displaying said information on the portable electronic device 38. The method can be performed before, after or simultaneously with breaking the fragrance-filled seamless capsule 12 and the subsequent olfactory experience. Advantageously, the user can directly access information related to the fragrance, such as the fragrance composition, origin of the ingredients, supplier information, GREEN MOTION® index, and other details that may be relevant to the user, such as ratings and comments from other users or inspirational comments from the perfumer who created it. In another embodiment, the method further includes creating a file storing personal or product-related information, which can be stored on the portable electronic device 38 or on the remote server 40. According to an embodiment of the present invention, the method further includes rupturing the capsule shell 22 by applying a disruptive force sufficient to release the liquid core 24, which is then absorbed by the adjacent absorbent medium 14, thereby gradually transporting the fragrance compound over a period of seconds towards the outer paper cover 16, and thereafter dispersing into the adjacent surroundings, allowing a person to experience the fragrance compound.
[0073] The present invention will now be illustrated by the following examples, which should not be construed as limiting the scope of the invention.
[0074] Working Example: General procedure for preparing the external aqueous phase: A measured amount of process water is heated and the hydrocolloid gelling agent is mixed therein until complete dissolution is achieved. Fillers, crosslinkers, and / or other additives are added and the resulting mixture is stirred and co-extruded to produce frangible seamless capsules. Exemplary formulations for preparing the external aqueous phase of the gellable mixture are shown in Tables 1 and 2.
[0075] [Table 1]
[0076] [Table 2]
[0077] General procedure for preparing the internal oil phase liquid core: Mix the desired amount of fragrance ingredient with a measured amount of non-glyceride solvent. Optionally, a small amount (<10 wt%) of ethanol may be used to homogenize the liquid core. The final liquid core formulation should be a stable liquid at room temperature. Exemplary formulations of various liquid core formulations including fragrance, isopropyl myristate (IPM) solvent, and ethanol are shown in Table 3.
[0078] [Table 3]
[0079] A general procedure for preparing capsules: the external aqueous phase of the gellable shell mixture and the internal oil phase of the liquid core are each pumped through an immersed coaxial nozzle assembly, thereby forming a concentric composite stream that is broken into individual concentric droplets by vibrational energy imparted thereto. The output of the coaxial nozzle is immersed in a carrier fluid (e.g., medium chain triglyceride (MCT)) at a temperature lower than the gelling temperature of the gellable mixture. This cools the gellable shell mixture and forms the hydrated shell portion of the capsule. The capsules thus formed are then aged at 4°C for about 1 hour, collected, and centrifuged to remove most of the residual MCT. The centrifuged capsules are mixed with a portion of a desiccant (e.g., silica or starch), and then air-dried at 35°C until the moisture content of the dried capsules is reduced to the desired amount (<5% moisture by weight), and then collected and sieved.
[0080] The dry, frangible, fragrance-filled capsules prepared according to embodiments of the present invention have a uniform and smooth appearance, are spherical or substantially spherical (i.e., shape ratio >0.9), and have a desired hardness (C i ) and elasticity (see Table 4).
[0081] [Table 4]
[0082] A dry, frangible fragrance-filled capsule 12 is combined with an absorbent medium 14 and wrapped in an outer paper cover 16 to form the fragrance delivery device 10, and is manufactured using standard or modified filter manufacturing techniques and equipment equipped with a capsule inserter.
[0083] [Table 5]
[0084] [Table 6]
[0085] Sensory Testing and Comparison: As shown in Figures 5 and 6, a conventional perfumer's fragrance blotter strip (150 mm x 7 mm) dosed with a measured amount of fragrance composition equivalent to the amount of capsule core (22 μL) was compared to the fragrance delivery device 10 of the present invention made with device 1 or 2 in Table 6. Eight panelists tested the fragrance delivery device of the present invention against the conventional blotter every day for 15 days except weekends. Fragrance A was evaluated at specific time intervals (0 hours, 2 hours, 3 hours, 4 hours, 5 hours, 6 hours, and 2-15 days) for top, heart, and bottom notes (Figure 6), as well as overall fragrance strength (Figure 5), and rated on a scale of 0-10. It was demonstrated that while the conventional blotter provided a stronger sensory experience in the first 2 hours, the fragrance delivery device 10 of the present invention was significantly longer lasting even after several days. Furthermore, the fragrance delivery device of the present invention provided better and longer lasting diffusion of the top and heart notes compared to the conventional blotter. Furthermore, the fragrance delivery device 10 of the present invention allows the user to smell the top and bottom notes simultaneously, especially on the first day of evaluation. Advantageously, the fragrance delivery device 10 of the present invention also comprises multiple fragrance-filled seamless capsules, which has the added benefit of allowing the destruction of another capsule even after several weeks.
[0086] These sensory panel results were confirmed by HS-GC / MS analysis, which showed that the fragrance delivery device of the present invention had quantitatively more fragrance remaining after 24 and 48 hours than the conventional blotter. The evaporation of fragrance on the device of the present invention and on the standard blotter was studied by measuring the residual fragrance A over time. For this, a 7890 gas chromatograph (Agilent) equipped with two injectors and two detectors (FID and MS detector 5977MSD Agilent) was used. The analytical system was driven using ChemStation software (Agilent, version E01.00.237). A 2 cm section was cut around each capsule of the device of the present invention. A 2 cm section of the blotter was also prepared. T0: The capsule of the device of the present invention was cracked and 22 μL of fragrance was deposited on the blotter section with a micropipette. The fragrance deposited on the blotter was the same as in the core capsule (fragrance A in 50% isopropyl myristate), and 22 μL represents the volume of one capsule. Extraction of the fragrance remaining in each device was performed after different evaporation times by precise addition of the internal standard (20 mg of a 30% solution of methyl octanoic acid in heptane) and 10 mL of dichloromethane. The samples were stirred at 300 rpm for 30 min on a shaking table. The organic phase was filtered through PS and injected into a GC-MS for identification and quantification. The quantification approach uses FID integration data. Compliance with the ISO11024 standard was previously verified. The internal calibration curve is determined by four reference solutions containing different ratios of fragrance and internal standard in 10 mL of dichloromethane. The fragrance quantified at T0 is defined as the amount of fragrance available in each device.
[0087] The present invention has been described by way of a description of one or more embodiments thereof, and while the embodiments have been described in considerable detail, it is not intended that the appended claims be restricted or limited to such details. Additional advantages and improvements will readily occur to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative products and / or methods, and examples shown and described. The various features of the exemplary embodiments described herein may be used in any combination. Thus, departures may be made from such details without departing from the scope of the general inventive concept.
