    A recipient for containing a beverage that supports a caustic image generator and a method for generating a caustic image of a recipient for containing a beverage.
    FIELD OF THE INVENTION
    The present invention relates to a container for containing a beverage that supports a caustic imager, more specifically a glass container for carbonated beverage or a metal beverage can. In addition, the present invention relates to a method for generating a caustic image of a container for containing a beverage.
    BACKGROUND OF THE INVENTION
    In product marketing, eye-catching packaging designs are extremely important, as are creating logos, brand names, etc. with a striking appearance. A recently developed technique in product packaging design is to generate a caustic image design by providing a caustic image-maker to the package that improves the attractiveness and visibility of the product.
    Recently, receptacles such as perfume or whiskey bottles have been proposed that include a caustic imager. The combination of computer algorithms for designing a container incorporating a caustic imager and highly precise molding provides a perfume cap or whiskey bottle that redirects incident light, thereby creating a brand logo or
    BE2017 / 5812 An image is created on a receiver such as a table, a wall, a screen.
    An important problem, however, is that in the packaging industry, and especially for the decoration of beverage containers, there is a clear tendency towards flexibility and personalization. It is clear that in such a context the use of pouring techniques for producing beverage containers that support a caustic image-maker is not sufficient.
    Another problem is that casting techniques are limited to use with plastic and glass, excluding, for example, metals or cardboard beverage containers that support a caustic imager.
    Another problem with regard to pouring techniques is that in order to obtain a glass container suitable for carbonated beverages with a strength and minimal internal bursting pressure, comparable to a blown glass container for carbonated beverages, it is mandatory to use significantly larger quantities of glass to obtain a higher wall thickness.
    In addition to casting, 3D printing is also proposed for producing containers that support a caustic image-maker (http: //web.media.mit.edu/~neri/MATTER.MEPIA/Theses/Joh n Klein MIT MSc Thesis Submission%) 20 (1) .pdf). However, the speed and production costs of 3D printing of articles, more specifically beverage containers, is not comparable with the speed, production costs and efficiency obtained with mass production facilities.
    BE2017 / 5812
    In view of the above, it is an object of the present invention to expand the range of material types that can be used to produce containers for containing a beverage adapted to generate a caustic image.
    More specifically, it is an objective to provide conventional containers for containing a beverage adapted to generate a caustic image.
    In addition, it is an object of the present invention to provide a method for obtaining receptacles comprising a caustic image-maker in a comparable inexpensive, fast and easily modifiable manner, and to bring its production process more to the field of digitization.
    It is a further object of the present invention to provide a method wherein a caustic image design can be made into suitable design elements for carbonated beverage containers, more specifically for blown carbonated beverage containers with a conventional glass wall thickness, strength and minimal internal burst pressure values. .
    Another object of the present invention is to provide a method that enables the production of metal containers that support a caustic image-forming device, more specifically carbonated beverage cans, and cardboard containers such as beverage cartons.
    Summary of the invention
    BE2017 / 5812
    The present invention is directed to a container for containing a beverage comprising a printed caustic imager on its outer surface.
    In addition, the present invention is directed to a method for generating a caustic image of a container for containing a beverage, comprising printing a refracting and / or reflecting geometry on at least a portion of the outer surface of the container, characterized because the geometry is a caustic imager.
    The container for containing a beverage is more particularly a carbonated beverage container.
    Detailed description of the invention
    The caustic image patterns are integrated light patterns that are created by materials that focus or deflect incident light through refraction or reflection. Caustic light patterns are known as random side effects that, for example, are visible at the bottom of a swimming pool, or are generated by many glass objects, such as drinking glasses or bottles. However, methods are known in the art for controlling caustic patterns to form a desired shape by optimizing the three-dimensional geometry of the reflective or refracting surface that generates the caustic light, described throughout this text as the caustic image-maker .
    In the context of the present invention, a container for containing a beverage can be any
    BE2017 / 5812 type of bottle, drinking glass, beverage can, of any shape, material, or size. The beverage that is included, or intended to be included, can be any type of beverage, and in particular carbonated beverages, such as carbonated water, soft drinks and beer.
    A caustic image pattern, or caustic design, generated by a method or container of the present invention can include any type of image, logo, text, graphic art, encoding a wall, a table, a screen, and the like.
    In a first embodiment of the present invention, a receptacle for containing a beverage is provided comprising a printed caustic imager on at least a portion of its outer surface. By applying to the container a caustic imager that is printed, any type of container, preferably made from inexpensive material, such as glass, plastic, metal, cardboard, and produced on an industrial scale, can easily and quickly be modified in a way that meets the trend in beverage container decoration with a view to flexibility and personalization.
    A container for containing a beverage according to the present invention can have a curved outer surface, i.e. at least the portion that supports the caustic imager can have a certain degree of curvature. Such a curvature can be at least in part from a cylindrical, conical, or spherical shape, or any shape that uses it
    BE2017 / 5812 is used for drinking glasses or containers for drinks. Because the refractive and / or reflective behavior of a curved surface differs from the refractive and / or reflective behavior of a flat surface, the geometry of a printed caustic imager on a curved outer surface can be adjusted versus a printed caustic imager on a flat outer surface to generate a similar, or substantially the same, caustic image pattern.
    In an embodiment of the present invention, a container for containing a beverage is provided wherein the printed caustic image generator generates a caustic image pattern mainly by reflection or mainly by refraction, or by a combination of both.
    The caustic image-generator can generate a caustic image by refracting and / or reflecting the visible light spectrum. A substantially visible portion of the visible spectrum can also be used. In such a case, for example, the caustic image-forming material or the outer surface of the receptacles can absorb the portion of the spectrum that is not refracted or reflected. In the case of a visible non-transparent container such as a metal beverage can or a ceramic drinking cup, the caustic image-maker can mainly reflect the visible spectrum, while in the case of visible transparent containers such as drinking glasses and glass bottles, the caustic image-maker can mainly refract the visible spectrum.
    BE2017 / 5812
    In an embodiment of the present invention, the printed caustic imager may comprise any type of material suitable for printing three-dimensionally, thereby forming a refracting and / or reflecting geometry on a container for containing a beverage, ie any material that can be printed on such a container by a suitable three-dimensional digital printing technique.
    Examples thereof are three-dimensional printing techniques based on extrusion deposition, photopolymerization, or inkjet printing or laser ablation, laser sintering or other powder bed printing techniques, etc. Examples of materials can be thermoplastics, metal alloys, photopolymers, resins, or compositions thereof, or inkjet inks.
    The caustic imager is preferably printed with inkjet ink.
    An advantage of a caustic image-maker printed with inkjet may be that it initially has a smoother surface after printing in comparison with other three-dimensional printing techniques, so that expensive and time-consuming post-processing steps, such as polishing, can be prevented.
    A caustic imager printed on a container according to the present invention can comprise one or more ink layers, preferably energy-cured ink, so that the container can be exposed to heat treatment, such as pasteurization, without damaging the caustic imager. Providing a heat-resistant caustic imager is especially important for
    BE2017 / 5812 pasteurized beverage bottles and cans, and for beverage containers for hot drinks.
    In a further embodiment according to the present invention, a container for containing a beverage can be provided in which a printed image is present between the printed caustic imager and the outer surface. Such a printed image can include any type of image, logo, text, law text, graphic art, coding (QR code, barcode). Thus, the recipient can support a printed image of any type and simultaneously generate an identical caustic image design, or a caustic image design of each type.
    The printed caustic imager preferably comprises colorless transparent inks to achieve optimum refraction, although translucent colored inks are also possible; the latter can generate a colored caustic image design.
    Not only the three-dimensional geometry of the caustic image-maker, but also the reflective and refractive properties of the ink, or combination of inks, influence the generated caustic image design.
    Therefore, in an embodiment of the present invention, the caustic imager may comprise a combination of more reflective and more refractory inks.
    In addition, a mixture of inks with different refractive indexes may also be present in the caustic image-generator.
    Alternatively, or in combination with the foregoing embodiments, the caustic image
    BE2017 / 5812 comprises a layer of more reflective material, e.g. a (partially) metal-containing ink or a foil, under a three-dimensional geometry of more transparent ink. Or, the caustic imager may comprise a three-dimensional geometry of more transparent ink, with on top a at least partial layer of a more reflective coating.
    In general, a receptacle, or at least the portion of the outer surface that supports the caustic imager, can be made of any type of material on which a caustic imager can be printed, more specifically with inkjet
    printed such as cardboard, glass, plastic, metal (more specific steel or aluminum), or a combination thereof. In a embodiment from the present invention is going to be and method provided for the
    generating a caustic image of a receptacle for containing a beverage, comprising printing a caustic imager on at least a portion of the outer surface of the receptacle.
    By printing the caustic imager onto the container, any type of container for containing a beverage, preferably made from inexpensive material, such as glass, plastic, metal, cardboard, and produced on an industrial scale, can be easily and quickly be efficiently and efficiently modified, thereby meeting the trend in beverage container decoration with a view to flexibility and personalization. More specifically, conventionally used containers for carbonated beverages can easily be modified
    BE2017 / 5812 for generating a caustic image, without compromising important properties such as strength, minimum internal burst pressure values, oxygen diffusion, etc.
    More specifically, a glass container supporting a caustic imager can be obtained with an internal burst pressure of at least 7 bar, or at least 8 bar, or at least 9 bar.
    Any technique suitable for printing a three-dimensional geometric structure on a beverage-containing container can be used, such as, for example, three-dimensional printing techniques based on extrusion deposition, photopolymerization, or inkjet printing.
    Depending on the topography, transparency, reflective and refractive properties, and the fact that the generation of a caustic image is intended to be displayed in a filled or empty state, the geometry and / or material used for printing the caustic imager.
    As already explained above in this description, the outer surface on which the caustic imager is to be printed may have a certain degree of curvature, depending on the type of container. Because the geometry of a caustic imager on a curved surface differs from the geometry on a flat surface, not only must the printing equipment be suitable for printing on curved surfaces, but also the printing process and the process parameters must be suitable for printing three-dimensional caustic image-forming structures
    BE2017 / 5812 that are more demanding than caustic image formers that are provided for a flat surface.
    In order to obtain the necessary processing speed and throughput as required in industrial processes, a cylindrical curvature may be preferred because containers with such a cylindrical curvature, e.g. bottles, glasses, beverage cans with a cylindrical body or at least one cylinder where the caustic image -former must be printed, may be very suitable for processing in industrial rotary printing devices, as further specified in this text.
    In addition, as already briefly explained above, three-dimensional printing is a digital printing technique, that is, custom-designed production of caustic image-generating receptacles can be achieved by simple selection of the desired caustic image and corresponding printing parameters from a library of computer-controlled caustic image formers .
    In a preferred embodiment according to the present embodiment, the printing of the caustic imager is performed by inkjet printing.
    An advantage of inkjet printing is that it allows the printing of a relatively flat three-dimensional caustic image-forming structure as compared to the printing of a caustic image generator that generates the same caustic image with an alternative three-dimensional printing technique, so that expensive and time-consuming post-polishing steps for improvement of the optical properties can be avoided.
    BE2017 / 5812
    Moreover, a smoother structure can be less susceptible to abrasion after manipulation of the container, which is especially important for beverage bottles and blocks that are manipulated in replenishments.
    Since small droplets of ink are sent on the surface during inkjet printing, it may be possible to make edges and other geometric irregularities in the surface smoother during the actual printing by applying compensation droplets after curing of a printed layer, as described in US2015093544 (A1 ).
    In a method according to the present invention, a combination of more reflective and more refractory inks can be used by printing from a plurality of different ink sources, and / or by means of a plurality of printheads.
    A mixture of inks with different refractive indexes can also be printed.
    In an alternative embodiment, a method according to the present invention may comprise depositing a reflective layer via printing or by adding a film, or any other technique, before printing a three-dimensional geometry of transparent inks. Or a three-dimensional geometry of transparent inks can first be printed which is then (at least partially) coated with a reflective layer.
    In order to obtain a three-dimensional structure, the caustic image-forming layer can be printed on the container via inkjet layer by layer. There must be no curing solvent or water-based
    BE2017 / 5812 inkjet inks are used; however, energy-curable ink is preferred, ie any layer of ink can be cured in any suitable manner, for example radiation cured by any suitable type of radiation such as, for example, ultraviolet, electron beam, or the like, or thermally cured in a convection oven , infrared lamps, or the like, or a combination of both radiation and thermal energy.
    Ink-jet printing techniques as used in the present invention can be piezo-electric ink-jet printing, continuous-type ink-jet printing, and thermal, electrostatic and acoustic drop-on-demand type.
    According to the present invention, three-dimensional inkjet printing processes can be used as described, for example, in WO2012093086 (A1), or WO2013167685.
    In an embodiment of a method according to the present invention, industrial inkjet printing apparatuses can also be used for printing the caustic imager such as, for example, described in WO2012022746 (A1) and WO201552240, which describes an apparatus for printing containers by means of of inkjet printing on a rotary device, a plurality of treatment stations including the print heads and optionally further devices required for pre-treatment and post-treatment of the containers.
    Another example is WO2015036334, which describes an apparatus for rotational
    BE2017 / 5812 printing on asymmetrical containers, preferably by digital printing.
    In an embodiment of a method according to the present invention, the caustic image generator to be printed can be processed with a computer from the desired caustic image design to be generated, i.e., the geometry of the surface of a real object must be reconstructed with only an image of the caustic image, called reverse computer processing of caustic image design.
    An example of a method for processing a caustic image-maker with a computer is described in US2013301139 (A1) comprising: segmenting a target image into a plurality of image pieces, each image piece corresponding to a lens piece in a two-dimensional array of lens pieces on a refractive surface; then, for each image piece, determining a plurality of areas in a source image corresponding to a visual appearance of the image piece, and determining, for the corresponding lens piece, a mapping for each of the plurality of certain areas that breaks light through the refractive surface at the eye of a viewer, assigning an agreement score to each of the plurality of mapping, and assigning one of the plurality of mapping to the figurine.
    Another method for reverse computer processing of a caustic image design is given in WO2016000926, incorporated herein by reference, which describes a methodology for designing a refractive surface,
    BE2017 / 5812 comprising providing a refractive object comprising a refractive surface with an initial geometry, determining a refraction of incident illumination through the refractive surface with the initial geometry to create a source beam distribution on a receiver; and determining a shape of the refractive surface of the refractive object such that a resulting radiation distribution on the receiver corresponds to a desired target irradiation.
    In a specific embodiment of a method for generating a caustic image design of a container containing a beverage, the caustic image-maker is processed with a computer to generate a caustic image of a filled container. In such a case, the optical properties of the container and the ink must also be taken into account, but also of the beverage to be included. For example, light incident on the caustic imager may already be refracted and / or reflected to a certain extent, depending on the alcohol content, glucose content, etc.
    The caustic image shaper can further be designed for projecting a caustic image onto a vertical surface such as a screen or wall, or onto a horizontal surface such as a table.
    In a further embodiment of a method according to the present invention, the method may further comprise a step of printing an image on the container, and the caustic imager can be printed over the image in a normal
    BE2017 / 5812 printing process step. Energy-curable inkjet printing is preferably used for reasons previously stated and because applying this embodiment through industrial inkjet printers can result in a high speed and a highly efficient caustic image-forming printing process on decorated containers.
    In particular in the case of generating a caustic image of a glass bottle for carbonated beverage that supports a cold-end coating (CEC), a method according to the present invention may comprise the step of removing the CEC before inkjet printing of the caustic image-maker. Adhesion as well as print quality of the caustic imager can be improved compared to the print quality on a glass substrate from which the CEC was not at least partially removed. Without wishing to be bound by theory, the assumed reason for an improved print quality is that by removing at least a portion of the CEC layer to a level where the CEC is almost completely removed, or where the remaining CEC layer has a thickness smaller than 20 nm, the homogeneity of the surface is increased and results in a reduced tendency of the mobile and low-viscous inkjet inks to move on the surface before being cured.
    In a preferred embodiment, the CEC can be at least partially soluble in water and can be removed at least partially by flushing with tap water, technical water, purified water or distilled water. Depending on the duration and the
    BE2017 / 5812 rinsing temperature, the level of residual CEC can be varied or optimized from less than 20 nm to two or a monolayers, or to a level where only individual traces remain on the surface, or until complete removal.
    In another embodiment of the present invention, a primer layer can be applied between the outer surface of the container and the caustic imager to be printed by ink jet to improve ink adhesion, ie on a CEC or on a hot plate. end-coating (HEC), or on a pyrosil. Such a primer can preferably be transparent and may comprise an adhesion promoter. Such a primer can also be oxidized by flame, corona, or plasma treatment to improve inkjet ink adhesion.
