WO2011014092A1 - Method and vessel for producing a stereoscopic and/or lenticular image in a liquid - Google Patents

Abstract

The present group of inventions relates to a method for obtaining optical (stereo and/or lenticular) effects in liquid media, and to a vessel for implementing said method. The method for producing a stereoscopic and/or lenticular image in a liquid contained in a vessel comprises forming a stereo and/or lenticular template, which is placed on the wall of the vessel, and using an optical system for producing a stereo and/or lenticular image from the template when the latter is viewed through the liquid. The optical system comprises a lenticular lens-type raster and a liquid contained in a vessel. The lenticular lens-type raster is arranged on one wall of the vessel and the template on the opposite wall. The focal distance of each lens of the raster is calculated based on the location of the focus on the template.

Description

 METHOD AND VESSEL FOR FOR PRODUCING STEREOSCOPIC AND / OR VARIO IMAGES IN LIQUID

Technical field

 The group of inventions relates to methods for

optical (stereo and / or vario) effects in liquid media for various purposes located in vessels.

 State of the art

 As practice shows, to a large extent, the marketing of products placed in a vessel depends not only on the quality of the products, but also on the performance of the vessel and the creative solutions embedded in its design. This is especially important for perfumes, vodkas, which are often used in the form of gifts and souvenirs, as well as mineral water.

 The basis of creative solutions in the claimed group of inventions is the use of such effects as a “stereo effect” and / or “effect”.

 The use of such effects is currently quite widespread in film and photography, in advertising, printing (calendars, postcards), etc.

 So, for example, in television systems stereoscopic images can be obtained using the method known from the published application of the Russian Federation for the invention N ° 93052685, cl. H04N 15/00, 1996

 Obtaining stereoscopic images on monitors of computers is possible through the method disclosed in the patent of the Russian Federation N ° 2339985, cl. G02B27 / 22, 2008

These effects, as well as the means for their preparation, are described in sufficient detail in the literature and there is no need to dwell on their description in detail. We only note that the use of the stereo effect allows you to get three-dimensional images, and the use of the vario effect allows you to get a change from one image to another when changing the viewing angle. The main elements for obtaining these effects are stereoscopic and / or vario images (templates) and optical elements - lenticular lenses that decompose the image in the corners and the user sees either a three-dimensional image (stereo) or images that vary depending on the viewing angle (vario) . The use of these effects is the basis of the claimed group of inventions, which makes it possible to obtain various high-quality spectacular images in a liquid placed in a vessel. This makes this product very attractive to the buyer. In addition, the use of such an effect in vessels with liquids allows to protect the liquid placed in the vessel from falsification.

 Templates for obtaining stereo and / or vario effects (stereo and / or vario templates) can be obtained in various ways. So, for example, an ordinary photograph can be divided into layers that move relative to each other. The result is a stereo image in which some layers are closer to the viewer, and others further. This is a very persistent method and it is used as a rule for small print runs of advertising media designed for an unassuming target audience.

Depth maps, point group methods, etc. are used as more complex methods for obtaining such patterns. These methods involve the use of rather sophisticated software, but they justify themselves when creating complex multi-angle images. For example, there is a known method for producing stereoscopic raster photographs, according to which parallograms are formed on a flat substrate from images of the left and right frames of a stereopair and a parallaxogram is placed at a constant distance from the linear raster, and the resulting images are divided into vertical stripes, equal to the width of the linear slit raster, and the parallaxogram is formed by replacing the stereo pair of even bands in the image of the left frame with the even numbers of the right frame of the right frame number Hereopar.

 (see RF patent N ° 2129725, class G03C9 / 02, 1999).

 This template allows you to get a stereoscopic image of photos.

 To obtain a stereoscopic and / or vario effect without the use of complex optical systems, in addition to a stereo and / or vario template, it is necessary to have optical elements - lenses. To achieve the specified technical result, lenticular rasters can be used. The lenticular raster is a set of lenses, the number of which per inch (Ipi) varies from 10 to 200, depending on the application. The term “lenticular” means “lens-like”. The term “lens lens” is also used. To obtain high-quality stereo and / or vario images, the correct selection of the parameters of the raster lenses is very important.

One such parameter is the frequency of the lenses that fit on an inch (measured in Ipi - lepses reiPSh). This parameter is determined based on the resolution of the human eye. So for small-format products (calendars, postcards), a raster with a frequency of 85 Ipi and higher is preferable. For outdoor advertising, rasters with a frequency of 10 - 20 Ipi, for decoration of exhibition stands - up to 75 Ipi, for souvenir products - more than 75 Ipi.

 The second parameter of the raster lenses is the angular resolution of each raster micro lens (determines the minimum angle within which separation of two adjacent angles is possible and, accordingly, the maximum possible number of varioframes or stereo angles for a given raster), which should be within 0.5 - 5 degrees. Outside this range of values, only one angle will be visible and no stereo or vario effect will be observed.

 To obtain stereoscopic images without the use of complex optical means, a device is known that contains two stands, one of which (near) is for mounting lenses, and the second (far) is for placing photographs forming a stereo pair. Stands are installed on the base at a distance from each other, which is calculated in a known manner and allows you to see the volumetric image in full size. The device is implemented in the form of a book - postcards, the base of which is the back of the cover made of paper or thin cardboard. To obtain a stereoscopic image, you need to open the book - postcard, spread the stands in such a way that they are located one after another and view the images through the lenses, observing the stereo image.

(see RF patent for utility model N ° 10525, class A47G1 / 14, 1999).

The stereoscopic effect is also used on decorative products. So, for example, a curtain made of transparent material is known, on the wrong side of which stereoscopic applications are placed (see RF patent N ° 2206463, class B44F1 / 06, 2003). Thus, the use of stereoscopic and vario effects, including on various products, is currently being carried out quite widely.

 In this group of inventions, these effects are used to obtain stereo and / or vario images in liquids placed in vessels, which can be used including as souvenirs or gifts.

 In practice, the use of vessels with the liquid placed in them in the form of souvenirs is very common. The most commonly used vessels are souvenirs.

 For example, a bottle is known with a souvenir placed inside it, made in the form of a ship, which is introduced into a bottle filled with liquid through its neck. To facilitate the placement of a souvenir in a bottle, it is made of metals with the “shape memory” properties.

(see published application of the Russian Federation N ° 94 020004, class B44C5 / 00, 1997) This solution of a bottle in the form of souvenir products is traditional, but in this case it must be borne in mind that a metal placed in a liquid can adversely affect the properties liquids.

 A well-known bottle is a souvenir, which contains a glass case closed by a cork, in which a silver jewelry is placed in a bag attached to the cork.

(see RF patent for utility model Ns8337, class B65D1 / 02, 1998).

This solution is also based on placing a souvenir bottle inside and is traditional, as above.

Known capacity for food fluid, made in the form of a bottle with a neck. Inside the bottle is a float made of impact-resistant food plastic, placed on which is made, for example, by spraying, a label of a noble metal or an alloy of noble metals. The label contains information about the manufacturer of the product, the date of production. A noble metal coin is attached to the bottom of the float, on which information is deposited, allowing the consumer to participate in lotteries organized by the manufacturer. The coin can also be made in the form of a souvenir, allowing you to collect a collection of, for example, zodiac signs. Naturally, the dimensions of the float and coins must be such that they pass into the neck of the bottle. When liquid (alcoholic or non-alcoholic drinks) is placed in a bottle, its transparency must be such that the information on the label is visually read.

(see Utility Model Patent N242028, CL B65D1 / 10, 2004).

 As a result of the analysis of the implementation of this capacity, it should be noted that, like the above, it is based on the premises inside souvenirs. It is very significant that these souvenirs allow the buyer to participate in the draws of goods, collections can be assembled from them, they are made of precious metals and have a certain value. In addition, using these souvenirs, it is possible to control the transparency of the liquid placed in the vessel. Naturally, this performance of the container, in comparison with the two above, is more preferable for use as a gift or souvenir.

Known utensils for drinking, designed for special occasions, made in the form of a bowl-shaped container with a support to give it stability. A vibration sensor and emitters associated with the control unit. The emitters are optically coupled to the cavity of a bowl-shaped container. Piezoelectric elements with red and green radiation were used as emitters. The emitter and sensor are connected to the control unit and the power source. During the celebration, when containers (for example, wine glasses) collide, electrical signals appear at the output of the vibration sensor, which are transmitted to the emitters through the control unit. Emitters through optical communication alternately emit different colors into the liquid (for example, champagne), that is, in the liquid in the bowl cavity the effect of the play of colors is created,

(see RF patent N ° 2100006, A47G19 / 02, 1997).

 As a result of the analysis of the implementation of this vessel, it should be noted that its use allows to realize the color effect inside the liquid placed in the vessel, that is, in this solution, the optical properties of the liquid placed in the vessel are used. However, the execution of this dishware is very difficult, which complicates its practical implementation.

 The second direction, which determines the effective implementation of the products visited in the vessel, is to protect the placed liquid from falsification (fake), which is quite common.

To solve this problem, vessels are increasingly found on which means are placed that confirm the authenticity of both the vessels themselves and their contents. This, as noted above, to a large extent applies to the vessels used to place alcoholic beverages, soft drinks, perfume liquids, liquid medicinal media, various fuels and oils in them. To solve this problem, holograms have recently been used quite often, which are performed on the basis of being attached (glued) to the surface of the vessel and its presence is a confirmation of the authenticity of both the vessel itself and the product placed in the vessel.

 Thus, a vessel with a holographic label is known, which is attached to the vessel so that the holographic layer of the label is facing outward.

 (see, for example, published application Ns97109849, CL B65CZ / 18, 1997).

 Undoubtedly, such a label improves the appearance of the vessel, but does not protect its contents from falsification.

 A well-known vessel is a bottle for alcoholic beverages, on the outside of which a protective element is glued, representing a hologram applied to the base, which forms different images at different angles of view (see published application N ° 2007115812, class B64D15 / 00, 2007). This security feature confirms the authenticity of the bottle, but not its contents.

 A known vessel having side walls and a bottom. A holographic layer coated with a label with protruding edges is fixed on one outer wall of the vessel or directly applied to this surface. The label simultaneously acts as a substrate for the holographic layer and at the same time protects it from damage.

The light penetrating through the transparent walls and the transparent liquid illuminates the holographic layer, creating an image that the observer sees through the transparent wall of the vessel and the transparent liquid. The volume holographic image appears to be located inside the vessel, in its fluid. Hologram can also create intense highlighting of part of the liquid, including with shades of different tonality,

(see RF patent N22272761, class B65CЗ / 08, 2006) - the closest analogue for the method and device.

 As a result of the analysis of this solution, it should be noted that it allows one to obtain a volume holographic image in the liquid volume and at the same time control such a liquid parameter as transparency.

 The disadvantage of this solution is the impossibility of obtaining stereoscopic and / or vario effects, as well as the high cost of implementation due to the need to use a large hologram. This solution allows you to control only one fluid parameter - transparency.

 SUMMARY OF THE INVENTION

 The objective of this group of inventions is to develop a method for obtaining a stereoscopic and / or vario effect in a liquid and a vessel, in which the liquid is placed and which can be used as souvenir products, while at the same time protecting the contents of the vessel from falsification.

The objectives are provided by the fact that in the method of obtaining a stereoscopic and / or vario image in a liquid placed in a vessel, comprising forming a stereo and / or vario template that is placed on the vessel wall and using an optical system to obtain a stereo and / or vario image from the template when viewed through a liquid, it is new that the optical system includes a lenticular lens raster and a liquid placed in the vessel, the lenticular lens raster is placed on one wall of the vessel, and the template on the other a goy opposite, while the focal length of each raster lens is calculated from the condition of the focus on the template, which can be approximated to the lenticular raster by means of a plano-convex lens mounted between the lenticular raster and the template.

 The vessel is made of transparent material and contains a housing with a hole for filling and removing liquid, a lenticular raster is placed on one wall of the case, and a stereo and / or vario template on the other wall opposite, and the geometry of each lens of the lenticular raster is selected so that its focus, when placed in a vessel of liquid, was on the template, while the vessel can be equipped with a flat-convex lens placed on the body between the lenticular raster and the template, a stereo and / or vario template is applied to one of the sides of the label attached to the body so that the template faces the lenticular raster.

 When conducting patent research from the prior art, no solutions were identified that are identical to the declared one, and, therefore, the claimed invention meets the “new” condition of protection.

 The essence of the invention does not follow explicitly from solutions known from the prior art, and therefore, the claimed invention meets the eligibility condition "inventive step".

 The information set forth in the application materials is sufficient for the practical implementation of the invention.

 inventions.

 The claimed vessel may be made of glass or plastic. The material of the vessel must be transparent so that it transmits light rays. This condition is met by a wide range of materials currently used for the manufacture of vessels for various purposes. The vessel may have different shapes and sizes, which depend on the type of liquid placed in them, for the storage of which they are intended.

 So, for example, a vessel for natural, mineral drinking water is made in the form of a bottle of glass or a polymeric material with all the attributes inherent in a given type of product: body, neck, cork, etc.

 The vessel for alcoholic drinks is usually made of glass, of course, with a neck, cork, place for a label, etc.

 A vessel for storing oils, both food and industrial, fuels, various media, is usually made of polymeric material and, as already mentioned above, it has all the properties of vessels of this class.

 It should be noted that the liquids placed in the vessels must be sufficiently transparent to transmit light rays.

The implementation of the vessel will consider the example of the design of the bottle. The vessel contains a housing 1 with a bottom, a neck (hole) 2 for filling and removing liquid. The most acceptable shape of the body is when it has a horizontal plane in cross section in the form of a polyhedron with an even number of faces (square, rectangle). On one of the walls of the housing 1 there is a lenticular raster

3. The lenticular raster 3 can be formed directly on the vessel body during its manufacture. Raster 3 can be made separately on the basis of (plastic sheet) and fixed on the body, for example, glued along the contour. This is not essential for the execution of the vessel.

 The term “lenticular” is currently used quite widely. The term “lenticular” means “lens-like”. The lenticular raster is usually a set of lens microflows - lenticles.

 The manufacturing techniques of such rasters, as mentioned above, are known to those skilled in the art.

On the side (edge) of the housing 1, opposite to the raster 3, a stereo and / or vario template 4 is placed. This template (image) can be applied to the vessel body. The template can be formed on the substrate 5, which is attached (for example, by means of glue) to the vessel body so that the template faces the vessel wall (towards the raster 3). The template can be applied by printing. The peculiarity of this image is that, depending on the angle of view, it forms various pictures. The technology for obtaining such images is very complex, but they are known to specialists. A label 6 can be placed on the substrate 5 from the outside. The label can itself serve as the basis (substrate) for applying the template 4, but for this it must be sufficiently rigid. On the outer surface of the label 6 is applied the usual information characterizing the contents of the vessel information, advertising information and other related information that is generally accepted for each type of product placed in the vessel. In the case where a standard plastic plate with a lens row on one side with the lens focus on the opposite (smooth) side is used as a lenticular raster 3, it is necessary to optically transfer the image of the template to the focal point of the lenses, i.e. on the smooth side of the plastic. For this, a cylindrical flat-convex lens 7 is placed on the vessel body between the lenticular raster 3 and the substrate 5 with the template 4, which is fixed on the vessel body 1. The parameters of this lens should provide focusing of the image of the template on the smooth side of the plastic, taking into account the optical properties of the walls of the vessel and the liquid placed in it. Structurally, the installation of the lens can be carried out in various ways. So, in the wall of the vessel body on which the substrate is fixed, a pocket can be formed, in the pocket, for example, the lens 7 is fixed by means of glue. The pocket is closed by the substrate 5, which is fixed along its contour, and the template 4 is turned towards the lens. A protrusion, preferably of a closed shape, can be formed on the vessel body, in which a lens is fixed to the vessel body 1, and the substrate is mounted on the outer surfaces of the protrusion. The lens can also be an integral part of the vessel wall when casting. The essence of the declared decision does not change from this.

 2, the symbol L denotes the distance between the lenticular raster and the template. The symbol V denotes the distance between the lenticular raster and the plano-convex lens. The symbol U indicates the distance between the plano-convex lens and the template.

A method of obtaining a stereoscopic and / or vario effect in a liquid placed in a vessel is as follows. To obtain a stereoscopic and / or vario effect in a vessel, the implementation of which was described above, in a known manner pour liquid, for example, water, close the vessel.

 It is easy to notice that the optical system providing a stereo and / or vario effect includes a lenticular raster, vessel walls, a liquid placed in a vessel, a cylindrical plano-convex lens (if available, if a standard lenticular plate is used as a lenticular raster). The parameters of the elements of the optical system and the distance between them should be calculated so that the focus of each lens of the lenticular raster is on the surface of the template in one of its images.

 The calculation of the optical system is carried out according to the rules well-known to specialists (see, for example, B. M. Yavorsky and Yu.A. Seleznev, “Physics Reference Manual”, Moscow, Hayka, 1989, pp. 352–356. H. P. Zakaznov “Special issues of calculation and manufacture of optical systems”, Moscow, “Nedra”, 1967, etc.).

 If a flat-convex lens is used in the design of the vessel, the formula can be used to calculate the optical system:

1 / v = 1 / f - 1 / u, where:

 v is the distance between the lenticular plate and the plane - convex lens;

 f is the focal length of a plano-convex lens;

 u is the distance from the plane - convex lens according to the template.

The applicant, these calculations were carried out using the universal program OrtisWorks 2007, developed by Ortis. Given the calculated parameters for each liquid, an individual vessel is produced with the parameters of the optical system calculated for a particular liquid, and the liquid itself is part of the optical system of the vessel.

 When looking at the substrate through a lenticular raster, each lens of the lenticular raster provides its own calculated angle of refraction of vision, which varies taking into account the refraction of the walls of the vessel and the liquid placed in it. When the focus of the lens is found on the corresponding image of the template, a stereo and / or vario effect is observed, that is, a high-quality image in a liquid medium. In the presence of a flat convex cylindrical lens, the stereo and / or vario image from the template is projected by means of this lens onto the smooth surface of the lenticular plate facing the vessel body. Given that the focus of the lenses of this plate is on its rear surface, thereby providing a stereo and / or vario effect. In this case, the template is placed on the case inverted.

 Using such an optical system allows one to obtain various stereoscopic and / or vario images (pictures) inside the vessel that appear to be located in the liquid itself and change depending on the change in the angle of view, that is, the stereoscopic and / or vario effect is realized. The possibility of obtaining such an effect in a liquid medium placed in a vessel favorably distinguishes this product from similar products.

When pouring any other liquid into the vessel (counterfeit), the refractive index of such a liquid will be different, and this will lead to a change in the parameters of the optical system, which reduces the quality of the stereoscopic and / or vario - effect. Thus, by the quality of stereo or vario images, it is possible to judge the authenticity of the liquid placed in the vessel.

 The method will be more clear from the following example of its implementation.

A vessel is used for mineral water made of PET (polyethylene terephthalate), square cross section, horizontal plane, wall thickness 0.5 mm, wall distance 64 mm. Glass refractive index 1.46,

the refractive index of water is 1.33. As a template, an encoded image of two paintings is used. The number of raster lenses to be formed on the wall of the housing is 18. The width of one lens is 5 mm. The estimated focal length of the lens is 68 mm.

 To calculate the radius of each lens, the above program was used, for the calculation of which the above parameters were entered.

 As a result, the following indicators were obtained: the radius of each lens should be equal to 14 mm.

 It should be noted that the vessel may have a different cross section, for example, a circle. To obtain the above effects in this case, it is necessary to carry out the calculation according to known methods of the parameters of each lens of the raster 3, ensuring the position of its focus on the template 5.

 Thus, the implementation of the invention provides reliable protection of the contents of the vessel from counterfeiting. Considering that the possibility of obtaining a stereoscopic and / or vario effect characterizes the original design of the vessel, it can be successfully used as a souvenir.

Industrial applicability The vessel, the substrate, the lenticular raster are made according to technologies known to specialists, the shape and size of the vessels can be different. The parameters of the vessel for the implementation of the stereoscopic and / or vario effect are calculated in a known manner.
