Definitions

  • the present invention generally relates to at least partially transparent compositions intended for human or animal use and to the packaging of such compositions.
  • One embodiment of the present invention relates to an at least partially transparent container containing an at least partially transparent aqueous alcoholic composition.
  • the container comprises at least one polarizer that makes liquid crystals present in the composition visible.
  • Alcoholic compositions are well established products in the beverage and cosmetics industry today. Innovations in this segment mainly reside in new alcoholic drinks, alcopops, perfumes, after shaves or eau de colognes with functional care ingredients.
  • Alcoholic cosmetic compositions may be combined with proteins or phospholipids for skin care purposes, for example.
  • Perfumes usually contain significant amounts of essential oils.
  • alcoholic drinks may be combined with a lipid and/or protein content for a different mouthfeel and/or taste, for example.
  • Proteins usually render a composition opaque and often visually unattractive to the consumer. Protein-enriched compositions are therefore usually sold in an opaque packaging.
  • compositions are desirable.
  • hydrolyzed whey proteins that are clear in solution and therefore suitable for see-through bottles are available.
  • the inventors further found that if a transparent food grade composition comprising liquid crystals is viewed through a polarizer the liquid crystals are visible for the consumer who can check for presence and abundance of the active ingredients.
  • liquid crystals if viewed through a polarizer create a new visual effect for a transparent composition, with rainbow-like colours and/or black&white waves which are enhanced by movements or agitation. This dynamic visual effect is perceived as attractive by the consumer.
  • one embodiment of the present invention is an at least partially transparent container containing an at least partially transparent aqueous alcoholic composition, characterized in that at least a part of the surface of the container is covered by at least one polarizer, and the composition comprises food-grade liquid crystals.
  • the alcohol present in the composition is preferably ethanol.
  • the alcohol content of the composition is not particularly limited. Typically, the compositions may have an alcohol content in the range of 2 - 90 Vol-%. For alcoholic beverages, the alcohol content may be in the range of 2 - 50 Vol-%, preferably 3 - 15 Vol-%. For cosmetic preparations the alcohol content may be in the range of 5-90 Vol-%, preferably in the range of 40-80 Vol-%.
  • the container may be made from glass or plastic, for example.
  • the glass or plastic may or may not be coloured but has to be at least partially transparent.
  • Typical plastics that may be used for the production of the container include poly(ethylene terephthalate)(PET) or polypropylene (PP), for example.
  • the at least partially transparent container may consist of a partially transparent material.
  • the container may also only contain a window made from transparent material, while the rest of the container is made from opaque material or covered by an opaque label.
  • visible light can enter and exit the container through an at least partially transparent section.
  • the at least partially transparent section of the at least partially transparent container exhibits a degree of transparency of at least 75 % for at least a fraction of visible light.
  • the degree of transparency always relates to a material thickness of 1 cm unless otherwise indicated.
  • the at least partially transparent section is at least partially covered by at least one polarizer.
  • At least one polarizer may be attached to the outer surface of the container. Attaching the polarizer to the outer surface of the container has the advantage that it may be easily attached and easily removed, e.g., for recycling purposes.
  • a transparent container may be combined with polarizing labels. This would allow the visual inspection of the liquid crystals and at the same time it generates appealing visual effects.
  • the polarizer may also be attached to the inside of the container, if there is no risk associated with the direct contact of the composition with the polarizer.
  • the at least one polarizer may be an integral component of the container wall. This would have the advantage that the polarizer would then be even more scratch resistant.
  • any type of polarizer may be used for the purposes of the present invention.
  • the polarizer may be an absorptive polarizer and/or a linear polarizer.
  • the polarizer may be arranged around the whole container.
  • the direction of the polarizer is parallel or orthogonal to the axis of the container, a maximal amount of light will pass through the polarizer. As a result, the liquid crystals can be seen in front of a very bright background.
  • the direction of a polarizer is defined by its specific transmission axis, through which the light passes, limiting the oscillations of electromagnetic wavers to a specific plane.
  • the direction of the polarizer differs by 45° from the axis of the container, light passing through the container will pass through two polarizer planes with a difference in direction of 90°. As a result, only light diffracted by the liquid crystals will be visible. The liquid crystals can be seen clearly in front of a dark background.
  • any difference between the direction of the polarizer and the axis of the container may be chosen to fine tune brightness of the image and crystal contrast of the resulting image. It is a matter of very simple practical experimentation to determine the desired image.
  • the container may also contain more than one polarizer. If more than one polarizer is used, the directions of the polarizers may differ from each other.
  • the container may comprise an even number of polarizers, wherein the angle between the directions of polarizers located opposite to one another is identical for all polarizer pairs, whereas neighboring polarizers differ in direction.
  • the container may be any kind of at least partially transparent container that is commonly used to package drinks or cosmetic compositions.
  • the container may be a bottle or a sachet.
  • the liquid crystals may be any food grade liquid crystals.
  • the liquid crystals may be made from functional ingredients.
  • the liquid crystals may consist of proteins or phospholipids, for example.
  • liquid crystals are stable even in a wide acidic pH-range and therefore suitable for most beverages on the market today.
  • Liquid-crystalline phases are abundant in living systems.
  • biological membranes and cell membranes are a form of liquid crystals.
  • the liquid crystals may consist of protein. They may be protein fibril assemblies, such as ⁇ -lactoglobulin crystals.
  • ⁇ -Lactoglobulin is a common whey protein with many well known health benefits.
  • the food grade liquid crystals may have any size as long as it is large enough so that the crystals can be seen through polarizers. They may have average dimensions in the longest dimension of at least 400 nm, preferably at least 800nm.
  • the food grade liquid crystals may be present in any amount that is large enough, so that they are noticed through the polarizers. They may be present in an amount of at least 0.04 mg/ml of the composition, preferably at least 0.1 mg/ml of the composition.
  • the liquid crystals may be present in the composition in a concentration range from about 0.4% wt to 4.5% wt.
  • liquid crystals Any kind of liquid crystals may be employed in the framework of the present invention.
  • the food grade liquid crystals may be selected from the group consisting of thermotropic liquid crystals, lyotropic liquid crystals or combinations thereof.
  • the food grade liquid crystals may be present in a crystal phase selected from the group consisting of the discontinuous cubic phase, the hexagonal phase, the lamellar phase, the bicontinuous cubic phase, the reverse hexagonal columnar phase, the inverse cubic phase, the nematic phase, the smectic phases, the chiral phases, the blue phases, the discotic phases, or combinations thereof.
  • Crystals in different crystal phases produce differing images when viewed through polarizers. Hence, the proper selection of a crystal phase may be used to produce a desired image.
  • the crystal phase may also be selected in a way that the crystals are easy to produce and/or stable in the specific conditions of the composition.
  • nematic or smectic ⁇ -lactoglobulin crystals may be used for the purposes of the present invention.
  • Any kind of alcoholic composition may be used in the framework of the present invention as long as it is at least partially transparent.
  • Such at least partially transparent composition may have a degree of transparency of at least 50 %, preferably at least 75 %, even more preferred at least 85 % for at least a fraction of visible light.
  • the composition may be colored or colorless. It may be liquid or in gel form, for example.
  • the at least partially transparent composition may be selected from the group of consisting of alcoholic beverages, perfumes, eau de perfume, eau de toilette, after shaves, perfumes, eau de colognes, or skin care compositions.
  • Perfumes usually have an essential oil content in the range of 20 vol-% to vol-40%, eau de perfume in the range of 10 vol-% to 30 vol-%, eau de toilette in the range of 5 vol-% to 20 vol-% and cologne in the range of 2 vol-% to 8 vol-%.
  • the complete container of the present invention filled with the composition comprising the liquid crystals and comprising the at least one polarizer may have a degree of transparency of at least 35 %, preferably at least 50 %, even more preferred at least 75 % for at least a fraction of visible light.
  • Fractions of visible light are for example violet light with a wavelength of 380-450 nm, blue light with a wavelength of 450-495 nm, green light with a wavelength of 495-570 nm, yellow light with a wavelength of 570-590 nm, orange light with a wavelength of 590-620 nm, and/or red light with a wavelength of 620-750 nm.
  • Example 1 explains the preparation of b-lg ( ⁇ -lactoglobulin) powder to make liquid crystals.
  • BioPURE- ⁇ -lactoglobulin (Davisco Foods International Inc., Le Sueur, MN), which consisted of 95.9 % of ⁇ -lactoglobulin (variant A, 55.6%; variant B, 44.4%) was dissolved in Milli-Q water at 10 wt % concentration, adjusted to pH 4.6 using a 1 M HCl solution, centrifuged at 15 000 rpm for 15 min at 20°C using a Sorvall Evolution RC high speed centrifuge (Rotor SLA-1000), in order to remove non-"native"proteins.
  • Rotor SLA-1000 Sorvall Evolution RC high speed centrifuge
  • the supernatant was recovered and adjusted to pH 2, using a 1M HCl solution, and filtered through a 0.22 ⁇ m Millipore filter to further remove possible residual traces of insoluble proteins.
  • a dialysis was performed to remove traces of ions, which affect ⁇ -lactoglobulin aggregation.
  • the protein solution was dialyzed first against pH 2 Milli-Q water and second against Milli-Q water, using a Spectra-Por Dialysis Membrane 1, with a MWCO of 6000-8000 Da (Spectrum Laboratories, Inc., Los Angeles, CA). Dialysis tubes were previously boiled for 10 min in demineralised water in the presence of 1 mM EDTA and extensively rinsed with demineralised water.
  • the volume ratio between the solvent and the protein solution was kept constantly at around 40 during the dialysis.
  • the dialysis was performed at 4°C with at least 4 h between the dialysis buffer changes.
  • the solution was adjusted back to pH 2.
  • the solution was freeze-dried and placed in a desiccator at room temperature.
  • Example 2 describes the synthesis of the protein fiber-based liquid crystals.
  • Dialyzed and freeze-dried ⁇ -lactoglobulin powder was dissolved in Milli-Q water at a concentration of 2 % wt at room temperature, centrifuged at 10800g over a period of 1 h at 20°C using a Sorvall RC3C Plus centrifuge (DuPont, Newtown, CT), adjusted to pH 2 and filtered through a 0.45 ⁇ m Millipore filter.
  • the 2% ⁇ -lactoglobulin solution was then distributed in 100 mL flasks, which were hermetically sealed and placed in a water bath for heating at 90°C during 5h. Each flask contained a magnetic bar to stir the solution during the heating process. After heating, the flasks were immediately cooled by immersion in ice-water mixtures to quench the aggregation process. The solution was checked visually for transparency.
  • the protein solution was concentrated by a gentle concentration method at room temperature, in order to reach a final concentration of 4% wt. This was accomplished by a nitrogen flux circulating over the solution to concentrate, which dries the water vapor forming at its surface.
  • the solution was poured in a large beaker (at least twice the volume of the solution) which was hermetically covered with a two-hole top, one for the nitrogen flux input and one for air output.
  • the beaker was placed onto a plate stirrer (Vibramax 110, Heidolph Instruments, Germany) and was kept in agitation in order to avoid the formation of gel crowns on the surface during the drying process.
  • the concentrated solution was still liquid and clear. This procedure allowed the production of mixtures with beverages with a lower incorporation of water and enabled reaching higher final concentration of fibers.
  • Example 3 gives information on the polarizers used for our experiments and the tested packagings.
  • linear polarizers from ITOS GmbH (Germany), ref. XP38-18S. These are self-adhesive polarizers of 1.8 mm thickness, that can be sticked directly onto the packagings surface.
  • ITOS GmbH Germany
  • XP38-18S self-adhesive polarizers of 1.8 mm thickness, that can be sticked directly onto the packagings surface.
  • three types of packaging a small square PETG bottle, on which two polarizers were sticked on opposite surfaces, a rectangular-shaped bottle in glass (Nescafe jar), on which two polarizers were sticked on opposite surfaces, and a round-shaped glass bottle, on which one band of polarizer was wrapped ( Figure 1 ).
  • Example 4 shows the influence of the angle between the polarizers on the visual effect.
  • liquid crystals in these bottles produce the same visual effects as in the square bottles.
  • Example 5 demonstrated that liquid crystals are still present and visible when mixed with alcohol-water solutions.
  • Liquid crystals were found to be in particular well visible from 1% to 40% in ethanol. At 99% ethanol, the liquid crystals were very diluted and difficult to see between cross-polarizers.
  • Example 6 shows that liquid crystals can be incorporated in a commercial Eau de Cologne.
  • Liquid crystals were incorporated in a commercial eau de cologne, which has an alcohol concentration of 63%.
