Description

Fragrance product, dispenser and dispenser assembly

This application is a divisional application of the chinese patent application having application number 200680045500.0 (international application number PCT/US2006/039185), application date 2006, 10/6, entitled "fragrance product, dispenser and dispenser assembly".

Background

In many industries, product marketing can be a challenging and complex process, and despite the inherent product advantages, marketing approaches play an important role in product success and ultimately the success of the seller. In particular, in modern industries, such as fashion apparel, fashion accessories, cosmetics, fragrances, and other personal beauty products, the marketability of the product is determined in large part by the aesthetically pleasing packaging and appearance of the product. Thus, the ability to develop and display products in a unique and pleasing form is the most preferred consideration for modern product sellers.

In the case of personal beauty products, consumers may prefer to purchase products packaged in an aesthetically pleasing manner. Accordingly, manufacturers have developed techniques to conceal or hazy non-decorative and functional packaging components. Such techniques include the use of creative designs and colors on the exterior of the container. Other manufacturers provide such ornamentation on both the interior and exterior packaging components to conceal the packaging component or the product itself. In particular in the case of perfume products (fragrance products), the dispensing mechanism presents a considerable aesthetic challenge.

In view of the above, there is therefore a continuing need in the industry for improved product packaging. In addition, there is a continuing need for new and unique techniques for product design and packaging by manufacturers in order to gain a competitive advantage.

Disclosure of Invention

According to one embodiment, a fragrance product comprises a container containing a liquid fragrance and a dispenser assembly for dispensing the liquid fragrance, wherein the dispenser assembly comprises a transport assembly and a tube connected to the transport assembly and extending into the liquid fragrance. According to this embodiment, the tube and liquid fragrance each have a refractive index, and the difference (absolute value) between the refractive indices of the tube and the liquid fragrance is no more than about 0.04.

According to one embodiment, the container is substantially transparent. Various degrees of transparency are suitable, it being understood that the degree of transparency of the container varies with the packaging and the preference of the consumer. While opaque containers for fragrance products have been used in the industry, the containers of the present invention are typically at least translucent or more typically substantially transparent. The use of a substantially transparent container herein facilitates the viewing of the liquid fragrance and creates a clear and secure feel for the consumer of the purchased product. Most commonly, substantially transparent containers have one shade or tint, and generally not all of the shade or tint of the container material (typically glass, e.g., silica-based glass) itself.

With respect to liquid fragrances within containers, the term "fragrance" as used herein is intended to define a substance which is applied to a person and which emits a fragrance as its aesthetic and/or functional quality. According to one embodiment, the liquid fragrance comprises at least one of a base note (base note), a middle note (middle note) and a top note (top note). The term "note" may refer to a single scent of a fragrance, or it may refer to the volatility of certain aromatic compounds. Therefore, the ingredients classified as top notes have the highest volatility and thus the fragrance is short lived. Depending on the manufacturer, top note varieties of aroma compounds typically last only a few minutes, referred to as an "off-the-nose" or "heavy" note. Ingredients classified as middle notes (also known as heart notes) have a moderate volatility and appear after the top note has evaporated. Middle notes develop from any time about 10 minutes to 1 hour after initial application. The base fragrance component has the longest lasting fragrance, is a strong or thick fragrance, and usually develops about 30 minutes to 1 hour after the initial application. According to one embodiment, the perfume contains more than one fragrance profile component, which is referred to as a blend or combination of various fragrances, resulting in different and unique fragrances. In another embodiment, the perfume comprises a mixture of all three notes.

According to another embodiment, the liquid fragrance is classified as perfume (perfume extract), perfume, lotion, cologne or after-shave lotion. The difference between these classes of personal perfume compositions indicates the percentage of fragrance compounds present in the perfume. As used herein, a fragrance comprises about 20-40% aroma compounds, while a perfume comprises about 10-20% aroma compounds. The lotion comprises about 5-10% of the aromatic compound, the cologne comprises about 2-3% of the aromatic compound, and the aftershave comprises about 1-3% of the aromatic compound. Note that: although these values may vary from manufacturer to manufacturer, the classification levels employed by manufacturers are consistent. Regardless of the percentage differences between manufacturers, the present liquid fragrance is suitable as any fragrance composition regardless of the specific percentage of fragrance compounds present. Embodiments disclosed herein relate specifically to perfumes, fragrances, eau de toilette, and even more specifically to perfumes and eau de toilette.

Further with respect to liquid fragrances, according to another embodiment, the liquid fragrance generally comprises a carrier compound. As the name suggests, the carrier compound serves to dilute and carry the aroma compound, and suitable carrier compounds include oils or alcohols. Thus, suitable carrier oils include naturally occurring compounds, such as those derived from nuts and seeds. For example, common carrier oils are extracted from soybean, sweet almond, aloe, apricot, grape seed, calendula, olive oil, jojoba, peach kernel, and combinations thereof. Carrier compounds alcohol-based compounds may also be used, including, for example, ethanol, isopropanol, phenol, glycerol, or alcohols more commonly known as fatty alcohols, and combinations thereof.

According to yet another embodiment, the liquid fragrance further comprises an aroma compound. In one embodiment, the aroma compound is a naturally occurring organic compound, such as an essential oil or a mixture of essential oils. Generally, essential oils are a large class of volatile oils extracted from plants, fruits or flowers with characteristic odors. Typically, the characteristic odor of essential oils arises from the presence of two basic organic building blocks in the composition, which are either isoprene units or benzene rings. The aroma compounds may also be derived from another class of naturally occurring organic compounds, such as animal-based extracts. Alternatively, the aroma compounds can be synthetically produced to mimic odors or even reproduce chemical compositions to reproduce the characteristic odors of naturally occurring organic compounds. According to another embodiment, the aromatic compounds may be synthetically produced to produce a unique odor that is not reproducible from naturally occurring organic compounds.

Regardless of the nature of the compound (whether it be natural or synthetic), aromatic compounds emit a particular fragrance from aromatic functional groups. Typically, the aromatic functional group is composed of a chemical combination of the above isoprene units or benzene ring structural units. Thus, suitable aromatic functional groups include alcohols, ethers, aldehydes, ketones, esters, lactones, castor oil products, nitrites, terpenes, paraffins, and heterocycles or combinations thereof. Typically, one aromatic functional group produces one fragrance, but as discussed above in connection with the base, middle and top notes, liquid fragrances may contain mixtures of aromatic compounds and mixed fragrances. Thus, the liquid fragrance product may contain one or more fragrant compounds having one or more fragrant functional groups.

The liquid fragrance product may further comprise a fixative, such as a substance for binding various aroma compounds and allowing the aroma to last for a longer period of time. Suitable fixatives may include naturally occurring substances such as balsams, angelica, calamus, orris, or animal based extracts such as ambergris, civet, castoreum or musk. Alternatively, the fixative may be a synthetic or other material containing derivatives or equivalents of natural materials, such as phthalates or glycerin.

Typically, the liquid fragrance has a refractive index of less than about 1.50, for example in the range of about 1.32 to 1.45. In one embodiment, the liquid fragrance has a refractive index in the range of about 1.35 to 1.42, such as in the range of about 1.36 to 1.40. In other embodiments, the liquid fragrance has a refractive index in the range of about 1.37 to 1.39.

With respect to dispenser assemblies, dispenser assemblies typically include a mechanism for dispensing liquid fragrance, such as a delivery assembly. According to one embodiment, the delivery assembly comprises a pump for transferring the liquid fragrance product from the inside of the container to the outside (e.g. for administration to a human). Typically, the pump uses a pressure differential that is activated by various mechanisms, such as a button, trigger or ball (bulb) that is actuated by the consumer. According to another embodiment, the transport assembly comprises a pneumatic assembly. In one embodiment, the liquid fragrance is a perfume and the delivery mechanism is a pneumatic assembly to enable the perfume to be released to the consumer in the form of a mist to provide effective dispersion of the fragrance, e.g., over a large area on the body, to provide a large evaporation area for the perfume. Thus, in one embodiment, the delivery assembly comprises a nebulizer or atomizing nozzle for releasing the liquid fragrance in the form of a mist.

With respect to the tube, the tube provides a reservoir for transporting the liquid fragrance product from the container to the consumer via the delivery assembly. The tube extends into the liquid fragrance, which fills the tube to a specific level by capillary action. In one embodiment, the tube is a plastic material, in particular a fluoropolymer. According to one embodiment, the tube may comprise a fluoropolymer material such as Polytetrafluoroethylene (PTFE), tetrafluoroethylene and Perfluoroalkylvinylether (PFA), tetrafluoroethylene and hexafluoropropylene (FEP), tetrafluoroethylene and ethylene (ETFE), polyvinylidene fluoride (PVDF), Polychlorotrifluoroethylene (PCTFE), ethylene tetrafluoroethylene (EFEP), modified ethylene tetrafluoroethylene, polyfluoroacrylates, polytrifluoroacetate, tetrafluoroethylene and hexafluoropropylene and vinylidene fluoride (THV), and combinations thereof. Of the foregoing materials, ethylene tetrafluoroethylene (EFEP), tetrafluoroethylene and ethylene (ETFE), and a combined material of tetrafluoroethylene and hexafluoropropylene (FEP), and combinations thereof, are particularly suitable tube materials.

With further regard to the tube, according to one embodiment, the tube is made from a material having a refractive index of no more than about 1.50. According to another embodiment, the refractive index of the tube may be no more than about 1.45, 1.43, 1.40, or even no more than about 1.38.

With further regard to the tube, a material having suitable transparency contributes to a desirable, low-visibility optical effect of the tube when immersed in and containing the liquid fragrance. According to one embodiment, the tube is made from a material having a transparency of not less than about 80% based on the percent transmission of light having a wavelength of 500 microns through a 3mm thick sample. In another embodiment, the tube is made from a material having a transparency of not less than about 85% (or even 88%). In yet another embodiment, the tube is made from a material that is more transparent, such that the transparency is not less than about 90% (or even about 92%).

According to one embodiment, the tube is hollow, thin-walled, has a good geometry with an ID (inner diameter) in the range of about 0.1mm to about 3.0mm, for example 0.1 to about 2.0mm or 0.1 to about 1.0 mm. The ID of a particular sample was 0.95 mm. The OD (outer diameter) is generally in the range of about 0.25mm to 10.0mm, for example, 0.5 to 5.0mm or 0.5 to 3.0 mm. A specific example of OD is 1.65 mm. Typically, the tube has a uniform wall thickness in the range of about 0.05mm to about 3.0mm, for example 0.1mm to 1.0mm, most often in the range of about 0.1mm to 0.75 mm. A specific example of the thickness is 0.35 to 0.38 mm.

In the case of a tube, the tube is made from a material having a suitable crystallinity, which contributes to the low visibility optical effect of the tube when immersed in and containing the liquid fragrance. According to one embodiment, the crystallinity of the material comprising the tube is no more than about 13%, such as no more than about 11%. Typically, the crystallinity does not exceed 10%, for example not 8%. Indeed, certain embodiments have been found to have a crystallinity of no more than about 6%. Notably, the above crystallinity values are based on X-ray diffraction (XRD) measurements. Note that other crystallinity measurement techniques (e.g., Differential Scanning Calorimetry (DSC)) can provide different crystallinity data; however, the crystalline content specified herein is strictly quantified by XRD. The specific XRD characterization parameters are as follows:

voltage: 45kv, current: 40mA, XRD machine: bruker D8Discover w/Gadds detector, 0.3mm slit, 0.3mm collimation, Cu radiation, Goebel mirror (parallel beam), oscillating 0.5mm along the tube length, 5 frames (about 15 °/frame), 72 seconds/frame, ω 7 °, midpoint of detection frame 14 °, 29 °, 44 °, 59 °, 74 °.

According to a particular feature, embodiments (embodiments) can be prepared using a quenching procedure that facilitates the production of high clarity and/or low crystallinity tubes having particular significance in the context of thin-gauge, thin-walled tubes as described above. In one example, EFE-4040 (modified ethylene tetrafluoroethylene) was extruded to make a tube with an outer diameter of 1.65mm and an inner diameter of 0.95mm under the following conditions: melting temperature: 520 ° F to 540 ° F, linear velocity: 100 to 125fpm, quench bath temperature: 80-90 DEG F, distance between the quench tank and the extruder die head: 1". Further testing revealed that quenching is critical to ensure high clarity and/or low crystallinity. Samples of the same material without quenching were found to have a crystalline content of 18% (annealed at 155 ℃ for 1 hour), 13% (annealed at 155 ℃ for 5 hours) and higher (e.g., 29% and 33%). Such a comparative sample was also found to be cloudy and not able to achieve high clarity. It is expected that a fine size tube may contribute to achieving an overall uniform temperature profile by virtue of the thickness of the tube, thereby further improving transparency and/or reducing XRD crystallinity.

According to a particular feature, when the tube is immersed in and contains liquid fragrance, the difference between the refractive index of the tube and the liquid fragrance is no more than about 0.04, such as no more than about 0.035. As used herein, the term "delta" or "difference" of refractive index is the absolute value of the refractive index of the material comprising the tube minus the refractive index of the liquid fragrance. In certain embodiments, such systems having a tube immersed in and containing liquid fragrance have a delta of no more than about 0.030, such as no more than about 0.027 or 0.025. In some embodiments, the refractive index δ may be smaller, for example, no more than about 0.020 or 0.010. In fact, the refractive indices may be the same (zero δ).

According to embodiments herein, the refractive feature has a specific meaning. The prior art has developed container assemblies for storing, transporting and dispensing liquids that have structural components with refractive indices approximating that of the liquid. For example, US 6,276,566 describes a technique for providing a three-dimensional pattern within a container to mask functional components of a dispensing container. The disclosed delivery tube and liquid products (typically liquid soaps, shampoos, lotions, oils and beverages) have refractive indices within about 0.50 of each other, preferably within about 0.25 of each other. While perhaps in some applications, an index of refraction spread index (index of refraction spread) of this order of magnitude can result in a delivery tube with low visibility, it has been found that, particularly in the case of liquid fragrance products, the desired concealment or low visibility of the structural elements requires the refractive index to be more nearly the same. Further details are provided below in connection with the figures.

Furthermore, we focus on the use of fluoropolymers as described above. Certain fluoropolymers, such as ethylene tetrafluoroethylene (EFEP), tetrafluoroethylene and ethylene (ETFE), and tetrafluoroethylene and hexafluoropropylene (FEP), have been found to be particularly useful in the practice of embodiments of the present invention. In this regard, such fluoropolymers have not generally been used in perfume products, most of which is believed to be due to the high crystalline content of the polymer being particularly undesirable in achieving the target level of clarity in the tube. In contrast, embodiments herein use materials that control crystalline content, as well as materials having the transparency values described above. In addition, it is particularly noteworthy that embodiments herein utilize certain fluoropolymers that desirably have the refractive indices described above (most often no more than 1.45, 1.43, 1.40, or even no more than about 1.38). That is, the refractive index of polymers commonly used in the prior art is generally in the range of about 1.4668 to about 1.5894. Such polymers generally do not meet the hiding requirements of perfume products.

Detailed Description

The low visibility optical effect of a tube immersed in and containing a liquid is illustrated in the drawing. FIG. 1 illustrates a tube immersed in and containing a liquid fragrance, wherein the difference in refractive index between the tube and the liquid fragrance is about 0.10. The liquid fragrance here is a perfume with a refractive index of 1.37, while the tube has a refractive index of 1.47. The tube is made of polymethylpentene (PMP). As shown in fig. 1, the features of the tube (i.e., the edges of the inner and outer walls) are clearly visible within the liquid.

Figure 2 illustrates a system having a tube immersed in and containing a liquid. The delta for this system is about 0.02. The low visibility optical effect of the tube within the system is illustrated by a comparison between the systems of fig. 1 and 2. As shown in fig. 1, the features of the tube (e.g., inner and outer walls) are clearly visible, but these same features shown in fig. 2 are not apparent and are less visible. The delta decreases from 0.10 in fig. 1 to 0.02 in fig. 2, significantly reducing the visibility of the tube features, providing a low visibility optical effect.

Figure 3 illustrates a system in which a tube is immersed in and contains a liquid. The delta for this system is about 0.00 (zero). The low visibility optical effect of the system with low delta is illustrated by a comparison between the system of fig. 1 and the system of fig. 3. The tube features (e.g., inner and outer wall edges) that are clearly visible in fig. 1 are clearly less visible in fig. 3, so that the tube has a low visibility optical effect and is substantially invisible in the system.

Fig. 4 illustrates a system in which the tube is immersed in and contains a liquid, where δ is about 0.02. Here, unlike the embodiments described above with respect to fig. 1 and 2, the refractive index of the liquid is greater than that of the tube. The low visibility optical effect of the system with a delta of 0.02 is illustrated by comparing fig. 4 with fig. 1 and 2. As shown in fig. 1, the features of the tube (e.g., the inner wall edge and the outer wall edge) are clearly visible, but in fig. 4, these features are significantly less visible, so that the tube has a low visibility optical effect. In a comparison of the systems of fig. 4 and 2, the visibility of the tubes in each system is approximately equal. The comparison of the low visibility optical effects is enhanced by having air pockets in a portion of the tube shown in fig. 4. The presence of a portion of the tube with entrapped air represents a portion of the system where δ is significantly greater than 0.02. The inner and outer walls of the portion of the tube containing the entrapped air are more visible than the portion of the tube containing the liquid. This comparison further demonstrates that a delta of about 0.02 provides a low visibility optical effect.

Fig. 5 illustrates an embodiment of a fragrance product comprising a container 501 holding a liquid fragrance 503, and further comprising a dispenser assembly having a delivery assembly consisting of a cap structure 507 and a pump member 509. Depressing the pump member causes liquid fragrance to be dispensed (most commonly in an atomized manner). The dispenser assembly further comprises a tube 505 which substantially disappears as it extends into the liquid fragrance 503 and which acts to feed the delivery assembly with a continuous supply of liquid fragrance until the majority of the liquid fragrance is used. In fact, the embodiments demonstrate the extraordinary ability to achieve almost complete disappearance of the tube when it extends into the liquid fragrance. When full, the fragrance product appears completely "tubeless", and the tube is virtually indiscernible upon temporary inspection.

While the invention has been illustrated and described in the context of specific embodiments, it is not intended to be limited to the details shown, since various modifications and substitutions can be made without departing in any way from the scope of the present invention. For example, additional substitutions or equivalents may be provided, or additional or equivalent preparation steps may be employed. Accordingly, other variations and equivalents of the invention herein disclosed may occur to persons skilled in the art using no more than routine experimentation, and all such variations and equivalents are believed to be within the scope of the invention as defined by the following claims.
