Description

[0001] The present invention relates to a container for a liquid containing carbon dioxide, wherein the container has a base, a side wall with an outer surface and an inner surface, a bottom, a container volume for receiving the liquid, wherein the inner surface of the side wall and the bottom define the container volume, wherein the side wall is at least partially transparent so that an observer can see through the side wall into the container volume, and a decorative element arranged on the outer surface of the side wall.

[0002] Furthermore, the present invention relates to a method for manufacturing a container for a liquid containing carbon dioxide, comprising the steps of: providing the container, wherein the container has a base, a side wall with an outer surface and an inner surface, a bottom and a container volume for receiving the liquid, and wherein the inner surface of the side wall and the bottom define the container volume and wherein the side wall is at least partially transparent so that an observer can see through the side wall into the container volume, and forming a decorative element on the outer surface of the side wall.

[0003] Such containers, in particular drinking glasses and beverage bottles, for liquids containing carbon dioxide are known in many variations from the prior art.

[0004] There are virtually no limits to the color and design of decorative elements. Examples include decorative elements in the form of brands, logos, but also purely decorative and design elements.

[0005] What all state-of-the-art decorative elements have in common is that they are static and leave no moving impressions on the viewer.

[0006] In contrast, the object of the present invention is to provide a container for a liquid containing carbon dioxide, in which the viewer gets the impression of a moving or animated decoration.

[0007] This problem is solved according to the invention by a container with the features of claim 1. To solve the problem, the container of the type mentioned above has a effervescent element on the inner surface of the side wall.

[0008] Effervescence refers to the rising of carbon dioxide in liquids containing carbon dioxide or carbonic acid, i.e., in particular, beverages containing carbon dioxide or carbonic acid. The term is often used for liquids with a relatively low carbon dioxide or carbonic acid content, such as white wine or sparkling wine. However, for the purposes of this application, effervescence is also used to describe the bubbling of liquids with a higher carbon dioxide or carbonic acid content, such as mineral water or beer.

[0009] The underlying idea of ​​the present invention is to selectively stimulate the outgassing and rising of carbon dioxide in the form of one or more bubbles by arranging an aerating element on the inner surface of the side wall. This adds an additional, dynamic element to the decoration when the container is used, namely the bubble or multiple bubbles, which are also perceived by the viewer. To create this overall dynamic effect, it is essential that the decorative element is located on the outer surface of the side wall and the aerating element on the inner surface of the side wall.

[0010] One variant of an effervescent element is known as the nucleation point in high-quality sparkling wine and champagne glasses. There, a discontinuity is introduced on the inner surface of the base of such a glass, particularly on the glass's axis of symmetry. This prevents the sparkling wine from appearing flat in the glass. In contrast, according to the invention, the outgassing and effervescence are shifted to the inner surface of the side wall and linked to the decorative element on the outer surface of the side wall.

[0011] The aerating element is designed in such a way that when the liquid is poured into the container volume, the carbon dioxide can develop into a bubble or a plurality of bubbles on the aerating element and bubble up from the aerating element.

[0012] According to current knowledge, it is advantageous for the outgassing of carbon dioxide from a liquid at an effervescent element if the effervescent element forms a discontinuity on the inner surface of the side wall.

[0013] Therefore, in one embodiment of the invention, the effervescent element is designed as a projection or as a depression of the inner surface.

[0014] In one embodiment, the effervescent element has one or more edges and corners. Preferably, at least one corner or edge of the effervescent element has an edge angle of 135 degrees or less.

[0015] Surprisingly, the formation and bubbling of gas bubbles is pronounced when the effervescent element is manufactured on the inner surface of the side wall of the otherwise finished container using a separating manufacturing process. In one embodiment, this separating manufacturing process involves machining with a geometrically undefined cutting edge, such as grinding or brushing, or engraving with a mechanical stylus or electromagnetic radiation (particularly a laser). In this way, the effervescent element is provided as a section of the inner surface with a roughened finish.

[0016] As an alternative to roughening the inner surface, a coating can be applied to the inner surface to form a projection or a multitude of projections. In one embodiment, the effervescent element is formed as a coating on the inner surface of the side wall with a ceramic paint. Such ceramic paints exhibit a high surface roughness, which promotes the formation and bubbling of gas bubbles from the liquid.

[0017] It is understood that the aerating element is located below the liquid level in the container at a typical fill level.

[0018] In one embodiment of the invention, the container has a fill line on the outer surface of the side wall. In one embodiment of the invention, the aerating element is arranged below the fill line. "Below the fill line" here means in a direction from the fill line towards the base.

[0019] In one embodiment of the invention, the aerating element is arranged above the lowest point of the container volume. In one embodiment, the lowest point of the container volume is defined as the point or plurality of points on the inner surface of the container that, measured in a direction perpendicular to the base, have the smallest distance from the base.

[0020] In one embodiment of the invention, the container has a container opening, the container volume having a height, the height being measured in a direction perpendicular to the base of the container between the lowest point of the container volume and the container opening. In one embodiment of the invention, the distance of the aerating element from the lowest point of the container volume, measured in a direction perpendicular to the base of the container, is at least 5%, preferably at least 10%, and particularly preferably at least 20% of the height of the container volume.

[0021] In a further embodiment of the invention, the distance of the effervescent element from the lowest point of the container volume, measured in the direction perpendicular to the base of the container, is at least 10 millimeters, preferably at least 20 millimeters and particularly preferably at least 30 millimeters.

[0022] A container is understood to be an object suitable for storing a liquid. Drinking vessels fall particularly under this general term. For the purposes of the present invention, a drinking vessel is understood to be any drinking vessel, regardless of its material. However, a drinking vessel made of glass is preferred. Drinking vessels as defined in this application include beakers, handled items such as mugs, cups, and pitchers, stemmed vessels, as well as bottles or drinking bottles.

[0023] In one embodiment, a liquid containing carbon dioxide is a carbon dioxide-containing or carbonated beverage, for example sparkling wine (e.g. Champagne, Sekt or Prosecco), beer, mineral water or lemonade.

[0024] The advantageous design effect can, in principle, be achieved with all beverages containing carbon dioxide. However, it has been found that the formation and rising of the bubbles (also known as perlage) can be particularly pronounced with the use of an effervescent agent, especially in sparkling wine and beer, or generally in beverages where the carbon dioxide is formed in the beverage through fermentation and is not added separately.

[0025] Therefore, in one embodiment, the carbon dioxide-containing beverage is preferably a sparkling wine or a beer.

[0026] The base refers to the outer surface of the container on which it is placed during normal use. The base defines the normal viewing situation and therefore forms an important reference point for the decorative element and the effervescent element, i.e., for the decoration. A ring-shaped contact area between the container and a surface it rests on, such as a tabletop, is also referred to as the base.

[0027] The bottom of a container typically encompasses the lowest point of the container's volume.

[0028] In one embodiment of the invention, the base includes at most the inner surfaces defining the container volume up to a distance of 5 mm from the lowest point. This distance is measured in a direction perpendicular to the base.

[0029] In one embodiment of the invention, the decorative element and the aerating element are designed and arranged such that, when the liquid is poured into the container, the decorative element and a bubble of carbon dioxide rising from the aerating element are perceptible to the observer as a partially animated graphic design. In other words, in one embodiment, the decorative element and the aerating element are logically related to each other.

[0030] In one embodiment of the invention, the decorative element and the effervescent element are arranged on opposing inner and outer surfaces of the same section of the side wall.

[0031] In one embodiment of the invention, the container has rotational symmetry about an axis of symmetry oriented perpendicular to the base. In such an embodiment, the decorative element and the aerating element are preferably spaced apart from each other by a maximum of 180 degrees in the circumferential direction. Preferably, in such an embodiment, the maximum circumferential distance between the decorative element and the aerating element is 90 degrees or less.

[0032] In one embodiment of the invention, the decorative element and the effervescent element are arranged such that, when the liquid is poured into the container volume, the decorative element and a bubble of carbon dioxide rising from the effervescent element can be observed simultaneously by the viewer.

[0033] In one embodiment of the invention, the decorative element and the effervescent element are arranged such that the decorative element conceals the effervescent element. In other words, in such an embodiment, the decorative element and the effervescent element are located in essentially the same position in the circumferential direction.

[0034] Such a covering of the effervescent element by the decorative element has the advantage that the effervescent element cannot be perceived by the viewer as a contamination of the container on the inner surface.

[0035] It has been shown that a majority of effervescent elements on the inner surface of the side wall are not perceived as contamination, especially when the effervescent elements themselves are arranged in an orderly and regular manner or in the form of a decoration.

[0036] In one embodiment of the invention, the container has a container opening. In another embodiment, where the container is a drinking glass, the drinking rim defines the container opening.

[0037] It has been found that the design impression resulting from the interplay of the decorative element and the bubble(s) that form on the effervescent element and bubble up from there also depends on the shape of the container above the effervescent element.

[0038] A clearly perceptible impression for the viewer, adjustable in speed of the rising gas bubbles, can be created if the gas bubbles brush along the inner surface of the side wall as they rise.

[0039] Therefore, in one embodiment of the invention, the aerating element is arranged such that the inner surface of the side wall extends radially inwards from the aerating element towards the container opening. In this way, gas bubbles formed at the aerating element bubble along the inner surface of the side wall towards the container opening.

[0040] A similarly good effect can be achieved if the inner surface of the side wall extends from the aerating element towards the container opening parallel to a straight line perpendicular to the base. This is the case, for example, with a cylindrical drinking vessel.

[0041] In one embodiment of the invention, the container opening has a maximum opening width. In an embodiment where the container opening is circular, the maximum opening width is equal to the diameter of the container opening. In another embodiment of the invention, the radial distance of the aerating element from the axis of symmetry is at least 5% greater than the maximum opening width, preferably at least 10% greater than the maximum opening width, and particularly preferably at least 15% greater than the maximum opening width.

[0042] In one embodiment of the invention, the effervescent element has a depression with a depth of at least 20 µm, preferably at least 50 µm. In another embodiment, the maximum depth of the depression is 100 micrometers or less.

[0043] In one embodiment of the invention, the decorative element comprises at least one layer of a printing ink, preferably a screen printing ink, a pad printing ink or a printed transfer image.

[0044] In one embodiment of the invention, a plurality of effervescent elements are provided on the inner surface of the side wall. These plurality of effervescent elements can be arranged distributed across the inner surface of the side wall and coordinated with the decorative element on the outer surface of the side wall.

[0045] According to the present invention, a combination of a container, as previously described in its embodiments, and an ultrasonic device is provided, wherein the ultrasonic device is arranged such that it couples ultrasound into the bottom or side wall of the container. This intensifies bubble generation and effervescence. In one embodiment of the invention, the ultrasonic device is integrated into a container base, in particular a coaster or beer mat.

[0046] The aforementioned problem is also solved by a method according to the independent claim directed thereto. To solve the problem, the method of the type mentioned at the outset further comprises, according to the invention, the step of forming a effervescent element on the inner surface of the side wall.

[0047] In one embodiment of the invention, forming the decorative element comprises printing the outer surface, preferably using a screen printing process or a pad printing process, or transferring the decorative element in the form of a printed transfer image.

[0048] Printing the decorative element on the outer surface of the side wall refers to direct printing onto the outer surface of the container. In this process, the printing ink is applied to the outer surface by a printing device, in particular a printing machine, such as a screen printing machine.

[0049] If a transfer image is chosen to create the decorative element, in one embodiment the desired decoration is first printed onto a carrier paper. The printed decorative element is then applied to the container in the manner of a sticker or decal. The applied transfer image is then cured, for example by applying heat (tempering) or by irradiation with UV light.

[0050] In one embodiment of the invention, the transfer image is printed with an organic color system.

[0051] In one embodiment of the invention, forming the effervescent element comprises machining the inner surface of the side wall using a subtractive manufacturing process, i.e., by material removal. In one embodiment, the subtractive manufacturing process is selected from a group consisting of - machining with a geometrically undefined cutting edge, e.g. grinding, brushing, - blasting with a particle jet, e.g. a sandblaster, - irradiation with electromagnetic radiation (especially with a laser) and - engraving, preferably with a mechanical stylus, in particular with an engraving robot, or a combination thereof.

[0052] If the effervescent element is produced by removing material from the inner wall, a rough, angular surface section is created, which forms the effervescent element.

[0053] As an alternative to removing material from the inner surface, in one embodiment the formation of the effervescent element includes applying a coating to the inner surface.

[0054] It is understood that applying a coating to the inner surface creates a protrusion on the inner surface. In one embodiment of the invention, a food-safe printing ink or coating is applied to the inner surface.

[0055] In one embodiment, the effervescent element is applied as a coating of ceramic paint to the inner surface of the side wall. Such ceramic paints have a high surface roughness, which promotes the formation and bubbling of gas bubbles from the liquid.

[0056] In one embodiment of the invention, forming the effervescent element comprises transferring the effervescent element in the form of a printed transfer image onto the inner surface.

[0057] If a transfer image is chosen to form the effervescent element, in one embodiment the desired arrangement of the effervescent element(s) is first printed onto a carrier paper. The printed effervescent element is then applied to the inner surface of the side wall, similar to a sticker or decal. The applied transfer image is then cured, for example by applying heat (tempering) or by irradiation with UV light.

[0058] In one embodiment of the invention, the transfer image is printed with an organic color system.

[0059] The invention is based on an overall design impression created by the decorative element and the gas bubbles generated at the aerating element during operation of the container. Therefore, the relative positioning of the decorative element and the aerating element relative to each other is essential for realizing the advantages of the invention. The deviation in the relative position between the decorative element and the aerating element must be comparatively small. In one embodiment of the invention, the tolerance of the relative positions of the decorative element and the aerating element is ±1 mm or less.

[0060] It has been found to be advantageous if the formation of the decorative element precedes the formation of the effervescent element. In this sequence, the decorative element, in one embodiment, serves as a register for machining the inner surface where the effervescent element is formed. In particular, in one embodiment, it is possible to perform the formation of the decorative element and the formation of the effervescent element inline, i.e., on the same production line.

[0061] In one embodiment of the invention, the effervescence element is formed using a laser beam through a side wall section opposite the effervescence point.

[0062] Further advantages, features, and applications of the present invention will become clear with reference to the following description of embodiments and the accompanying figures. In the figures, identical elements are designated by identical reference numerals. Fig. Figure 1 is a schematic side view of a goblet glass according to a first embodiment of the present invention containing a liquid containing carbon dioxide. Fig. Figure 2 is a broken-off schematic side view of the goblet glass made of Fig. 1 viewed from the opposite side. Fig. Figure 3 is a broken-off, schematic side view of a goblet glass according to a second embodiment of the present invention containing a liquid with carbon dioxide. Fig. Figure 4 is a broken-off schematic side view of the goblet glass made of Fig. 3 viewed from the opposite side. Fig. Figure 5 is a broken-off, schematic side view of a goblet glass according to a third embodiment of the present invention containing a liquid containing carbon dioxide. Fig. Figure 6 is a broken-off schematic side view of the goblet glass made of Fig. 5 viewed from the opposite side. Fig. Figure 7 is a broken-off, schematic side view of a goblet glass according to a fourth embodiment of the present invention containing a liquid with carbon dioxide. Fig. Figure 8 is a broken-off, schematic side view of the goblet glass made of Fig. 7 viewed from the opposite side. Fig. Figure 9 is a broken-off, schematic side view of a goblet glass according to a fifth embodiment of the present invention containing a liquid containing carbon dioxide. Fig. Figure 10 is a broken-off, schematic side view of the goblet glass made of Fig. 9 viewed from the opposite side.

[0063] The Fig. Figures 1 to 10 show variations of a goblet glass 1 as a container for holding a carbon dioxide-containing liquid in the form of a sparkling wine 2.

[0064] In the figures, the figure labeled with an odd number shows a schematic side view of the glass 1, as it would appear to a viewer. The figures labeled with an odd number show the glass 1 filled with sparkling wine 2, so that a liquid level 3 of the sparkling wine 2 is visible.

[0065] The figures labelled with even numbers each show the same glass as the lower-ranking odd-numbered figure, but in a view from the opposite side and without sparkling wine 2, so that effervescent elements 4 are also visible on the respective inner surface 11.

[0066] All figures show a glass of the same type with identical dimensions. In the embodiments shown, the glass is a stemmed glass 1. Each glass has a glass base 6, which forms a surface 7 on its underside. The glass 1 can be placed on this annular surface 7 when not in use. The stemmed glass 1 shown has a side wall 8 and a base 9. The side wall 8 naturally has an outer surface 10 and an inner surface 11. In addition to a decorative element 5, each glass 1 has a nucleating element 4 (glass made of the Fig. 5 and Fig. 6) or via a plurality of effervescent elements 4 (the glasses from the other figures).

[0067] The overall impression that a viewer receives from the respective glass 1 is determined by the optical and design interplay between the decorative element 5 and the effervescent element(s) 4. The relative arrangement of elements 4 and 5 to each other is particularly important for the design impression.

[0068] Furthermore, for the impression received by the viewer, it is also important that the distance A of the aerating element 4 from a lowest point 14 of the container volume 15, measured in a direction perpendicular to the base 7 of the container 1, is sufficiently chosen. In the examples, this distance A is at least 50 millimeters.

[0069] The decorative element 5 and the effervescent elements 4 are arranged on the outer surface 10 and the inner surface 11 of the side wall 8 in such a way that, when the glass is used with the carbon dioxide-containing liquid 2, a moving decoration 12 is created for the viewer, which consists of the decorative element 5 and the gas bubbles 13 that form on the effervescent elements 4 and bubble up from there to the liquid level 3.

[0070] In all the glasses shown, the decorative elements 5 are screen-printed onto the outer surface 10 of the side wall 8. In contrast, the effervescent elements 4 are incorporated as rough indentations into the inner surface 11.

[0071] In the examples shown, the effervescent elements 4 were produced with a laser beam by ablating glass material from the inner wall, such that the respective effervescent element is formed from a rough, angular surface section.

[0072] The overall design impression of the glasses is best determined by the decorative element 5 and the gas bubbles generated at the aerating elements during operation of the glass.13 For this reason, a relative positioning of the respective decorative element 5 and the aerating elements 4 to each other is essential.

[0073] Therefore, the respective decorative element 4 was printed prior to the laser cutting of the effervescent elements 4. The decorative element then serves as a registration mark for processing the inner surface 11 with the laser to form the effervescent elements.

[0074] In all embodiments of the Fig. 1 to 10, all aerating elements 4 are arranged at a distance from a lowest point 14 of the glass that is greater than 50% of the height of the container volume 15 of the glass 1. This distance is measured in a direction perpendicular to the base 7. The height of the container volume is the distance between the lowest point 14 and the drinking rim 16 of the glass 1, measured in a direction perpendicular to the base 7 of the glass 1.

[0075] Furthermore, all aerating elements 4 are arranged at a position on the glass from which the glass tapers upwards towards the drinking rim 16. In this way, gas bubbles 13 forming on the aerating elements 4 bubble along the inner surface 11 of the side wall 8 towards the drinking rim 16 and thus the opening of the container.

[0076] Fig. Figure 1 shows the arrangement consisting of a logo as a decorative element 5 and four nucleation points 4, which are concealed by the letter "O" at the top of the logo. During use of the glass 1 with the sparkling wine 2, carbon dioxide forms glass bubbles at the nucleation points 4, which then rise along the inner surface 11 of the side wall 8 towards the liquid level 3.

[0077] These gas bubbles 13 rising through the nuclei of the effervescent elements 4 are clearly visible to the observer, i.e. the gas bubbles are more concentrated than in the rest of the liquid 2.

[0078] The other embodiments of the Fig. 3 and Fig. 4, Fig. 5 and Fig. 6, Fig. 7 and Fig. 8 or 9 and Fig. 10 differ from the embodiment of the Fig. 1 and Fig. 2. due to the different graphic design. Fig. Figure 3 shows a crown as a decorative element 5 and three effervescent elements 4 on the three points of the crown 17. The embodiment from the Fig. 5 and Fig. Figure 9 shows a house 18 as a decorative element 5, with a single effervescent element 4 arranged on the inner surface 11 of the side wall 8 at the chimney of house 18. Therefore, when the glass 1 is filled, it looks as if the chimney is smoking. The smoke is represented by the gas bubbles 13. In contrast, the Fig. 7 and Fig. 8. A decoration that makes it look as if the roof of the house is lit up. 18. The Fig. 9 and Fig. Figure 10 shows an embodiment in which the effervescent elements 4 and the decorative element 5, in the embodiment shown an aircraft 19, do not overlap each other.

[0079] For the desired effect when viewing the glasses 1, it is important that the aerating elements 4 and the respective decorative elements 5 are each arranged in the same half of the glass when viewed in the circumferential direction. In other words, the respective decorative element 5 and all aerating elements 4 of the respective glass are spaced apart from each other by less than 180 degrees in the circumferential direction. In the embodiments of the Fig. 1 and Fig. 2, Fig. 3 and Fig. 4, Fig. 5 and Fig. For 6, 7 and 8, the distance in the circumferential direction is even less than 90 degrees.
