[0002] Cup glass and method for producing a cup glass

[0003] The invention relates to a beaker and a method for manufacturing a beaker.

[0004] A beaker is one of the most frequently used items in a laboratory. A versatile glass vessel, it can be found in almost every laboratory. It is used for a variety of tasks, such as mixing, heating, measuring, and transferring liquids, or dissolving substances. A beaker is typically made of borosilicate glass, a heat-resistant and chemically resistant material. Borosilicate glass can withstand sudden temperature changes (e.g., heating on a hot plate or rapid cooling) without cracking and is insensitive to acids, bases, and organic solvents, making it suitable for use with a wide range of chemicals. A beaker has a straight, circular cylindrical shape with vertical walls and a radially outward-projecting, tapered spout at the top to allow for precise and drip-free pouring of liquids.Beakers are available with various nominal capacities. A beaker is designed so that when filled to its nominal capacity, it can be handled in the usual laboratory manner without the risk of spillage, because the fill level of the nominal capacity is significantly below the upper rim of the beaker and therefore below the non-printable area.

[0005] On the outside of the beaker is a scale, usually in milliliters (ml), which allows for an approximate determination of the volume of liquid inside. According to DIN standards (especially DIN-ISO 3819), the beaker must, in addition to the scale, bear the nominal capacity, the name of the manufacturer and / or seller, and the type of glass, all of which must be permanently legible. It should also have a writing area that can be written on with a pencil. All of this information can be printed onto the glass container, for example, using a screen printing process, particularly a single-stage process. In this process, the printing ink is applied to the glass container through a fine-mesh screen printing screen stretched over a screen printing frame. Due to its cylindrical shape, the glass container rolls on the screen printing frame and the screen printing screen, rotating around its central axis.However, it is important to ensure that the screen printing frame does not collide with the radially protruding spout. This is achieved by maintaining sufficient axial distance between the screen printing frame and the spout during the rolling process. However, this means that an annular cylindrical area located axially directly below the spout 13 and the upper rim of the glass container cannot be printed. For beakers with the nominal dimensions specified in the relevant DIN standard, this annular cylindrical area represents the fill level of the nominal capacity. Consequently, no scale can be printed.

[0006] The scale can extend up to the nominal capacity. Therefore, the vast majority of beakers on the market do not allow for a precise reading of the volume of a liquid filled to the nominal capacity, because their scale does not extend to the nominal capacity. Figures 1 and 2, described below, illustrate this relationship. A similar problem exists with inkjet printing, as a collision between the printhead and the spout must also be avoided in inkjet printing.

[0007] It is therefore the object of the present invention to provide a method that enables the production of a beaker in which a precise reading of the volume of the liquid filled is possible in a simple manner even when the beaker is filled to a range around the nominal capacity.

[0008] The problem is solved by a method characterized in that a scale (2) is applied to a glass container having a radially outwardly projecting spout (13) at its upper rim (12), the scale having several horizontal marking lines (3), the uppermost marking line marking the nominal capacity of the beaker, the glass container having an outer diameter A which, taking advantage of the tolerance permitted according to the standard, corresponds to the maximum permissible outer diameter A according to the standard.

[0009] The problem is solved - alternatively or additionally - by a method characterized in that a scale is applied to a glass container which has a radially outwardly projecting spout at its upper edge, the scale having several horizontal marking lines, wherein the uppermost marking line marks the nominal capacity of the beaker, wherein the glass container

[0010] a. has a nominal capacity of 25 ml, an outer diameter A of 35.2 + / - 0.5 mm and a height H of 51.0 + / -1 mm, or

[0011] b. has a nominal capacity of 50 ml, an outer diameter A of 43.6 + / - 0.5 mm and a height H of 61.0 + / -1 mm, or

[0012] c. has a nominal capacity of 100 ml, an outer diameter A of 55.0 + / - 0.5 mm and a height H of 73.0 + / -1 mm, or

[0013] d. has a nominal capacity of 150 ml, an outer diameter A of 62.5 + / - 0.5 mm and a height H of 81.0 + / -1 mm, or

[0014] e. has a nominal capacity of 250 ml, an outer diameter A of 72.5 + / - 1 mm and a height H of 96.0 + / - 1 mm, or3

[0015] f. has a nominal capacity of 400 ml, an outer diameter A of 83.1 + / - 1 mm and a height H of 112.0 + / - 1 mm, or

[0016] g. has a nominal capacity of 600 ml, an outer diameter A of 93.5 + / - 1 mm and a height H of 127.0 + / - 1 mm, or

[0017] h. has a nominal capacity of 800 ml, an outer diameter A of 104.0 + / - 1 mm and a height H of 137.0 + / - 1 mm, or

[0018] i. has a nominal capacity of 1,000 ml, an outer diameter A of 109.2 + / - 1 mm and a height H of 147.0 + / - 1 mm, or

[0019] j. has a nominal capacity of 2,000 ml, an outer diameter A of 135.5 + / - 1 mm and a height H of 186.5 + / - 1 mm, or

[0020] k. has a nominal capacity of 3,000 ml, an outer diameter A of 156.0 + / - 1.5 mm and a height H of 212.5 + / - 1.5 mm, or

[0021] l. has a nominal capacity of 5,000 ml, an outer diameter A of 177.0 + / - 1.5 mm and a height H of 272 + / - 2 mm, or

[0022] m. has a nominal capacity of 10,000 ml, an outer diameter A of 229.5 + / - 1.5 mm and a height H of 358 + / -2 mm.

[0023] The term "outer diameter" refers to the outer diameter of the beaker below the spout.

[0024] According to the invention, it was discovered that the problem described above can be solved in a surprisingly simple manner by deliberately deviating upwards from the value for the outer diameter specified in the DIN standard, up to the maximum permissible deviation (5% according to DIN-ISO 3819). This can be easily achieved using the usual and long-established methods for manufacturing glass containers. In this way, the fill level of the nominal capacity is reduced below the height of the non-printable area. It was discovered according to the invention that, for example, the maximum permissible deviation of 5% for the outer diameter specified in DIN-ISO 3819 is unrelated to the manufacturing tolerances, which are significantly smaller in all conventional manufacturing processes (especially blow molding or production based on glass tube sections).The same applies analogously to beaker standards of other countries, such as the US standard E960-93.

[0025] This further achieves, according to the invention, that a scale can be printed where the uppermost marking line indicates the nominal capacity of the beaker.4

[0026] The user of a beaker manufactured in this way therefore has the advantage that he can precisely determine the fill level even when the beaker is filled with a liquid whose volume is, for example, in the range of 90% to 110% of the nominal capacity, since the uppermost marking line, which marks the nominal capacity of the beaker, is available to him as a reference.

[0027] The deviation from the DIN standard outer diameter according to the invention represents an effective modification that can be implemented without significant effort. At the same time, the requirements of the standard are still met. Thanks to the uppermost marking line, which indicates the nominal capacity, handling the containers becomes more intuitive and reliable for the user. This significantly reduces the risk of measurement errors.

[0028] The invention allows a scale indicating the nominal capacity to be applied by a screen printing process, particularly a single-stage process. The screen printing process enables precise and uniform application of the scale. Applying the scale in a single-stage process reduces production time and costs, as the entire scale can be applied in one pass. It is particularly advantageous to apply an additional print and the scale simultaneously in the single-stage screen printing process. In this process, the ink can be applied to the glass container, as usual, by means of a screen printing mesh stretched over a screen printing frame, particularly a rectangular one, with the glass container being rolled against the stretched screen printing mesh. Preferably, a single-stage screen printing process is used in which the stretched screen printing mesh is the only mesh against which the glass container is rolled.In this way, the entire printing device can be designed to be comparatively simple and uncomplicated.

[0029] In a particularly advantageous design, the scale is printed using a ceramic ink containing glass particles, which are fused to the glass of the beaker wall through a firing process. This fusion of the ceramic ink with the glass during firing ensures that the scale is permanently integrated into the surface. This also has the advantage that (if present) even the thinner and shorter marking lines remain permanently visible even with frequent use and cleaning.

[0030] There are no fundamental restrictions regarding the printing method used to apply the scale. For example, applying the scale using inkjet printing is possible.

[0031] In general, it can be advantageous to provide a print on the beaker spatially next to the scale, which includes at least one of the following print elements:

[0032] contains:

[0033] • Indication of the nominal capacity,

[0034] • Indication of the manufacturer's name

[0035] • Specifying the name of the provider

[0036] • Mention of a brand name

[0037] • Display of a logo

[0038] • Indication of the glass type

[0039] • Labeling field writable with a writing instrument, especially a pencil, • Representation of a retrace code.

[0040] The imprint can advantageously be arranged directly to the right or left of the scale. However, according to an independent inventive concept, which can be implemented in any beaker both in combination with at least one of the features described in this application and independently of the other features described in this application, it is particularly advantageous if the imprint is arranged to the right of the scale, in order to be able to position the scale further to the left and to avoid covering the scale with the right hand reaching opposite the spout, which will be explained in more detail below.

[0041] As already mentioned, it can be advantageous to apply the imprint and the scale together using a screen printing process, particularly a single-stage process. Applying the imprint and the scale together in a single-stage screen printing process is particularly efficient and cost-effective. The imprint and the scale can advantageously be printed together with a ceramic ink containing glass components, which are fused to the glass of the container wall by a firing process.

[0042] The scale can advantageously have a scale value adjacent to at least one of the marking lines, particularly to the left or right of at least one of the marking lines, which corresponds to the fill level volume marked by the respective marking line. The arrangement of the scale values ​​to the left of the marking lines is particularly advantageous with regard to preventing accidental covering by the grasping hand.

[0043] In a particularly advantageous embodiment (and according to a further independent inventive concept, which can be used in combination with at least one of the features in this application6

[0044] The scale (which can be implemented in any beaker, regardless of the features described in this application) has several first horizontal marking lines with a length L and a line thickness T, wherein at least one second horizontal marking line is arranged between each pair of adjacent first horizontal marking lines, having a length of 0.5L and a line thickness in the range of 0.6T to 0.8T. This design offers a number of advantages, particularly in its precise and practical handling. The combination of the first and second horizontal marking lines allows for improved readability of the volume of the liquid and facilitates the measurement of the liquid volume, which is crucial in many applications, especially in laboratories and industry.The first horizontal marking lines provide a clear and highly visible reference, allowing for a quick and accurate estimation of the volume of liquid poured into the gauge. These lines offer a stable visual reference, which is particularly helpful for precisely aligning the liquid's mouth when the gauge is held freely in the hand while reading the scale. The distinct design of these first marking lines, compared to the second set of lines, has the significant advantage of ensuring they remain clearly visible even at first glance and in challenging lighting conditions.The second horizontal marking lines, preferably positioned between the first marking lines, are shorter and thinner than the first, creating a clear visual distinction. This reduced length and thickness also ensure that the overall appearance of the scale remains uncluttered. Their narrower profile allows for quick and accurate readings even when the meniscus of the liquid is precisely aligned with one of the second marking lines. Furthermore, the optically finer second marking lines, in combination with the first, provide the user with precise orientation, particularly for intermediate values. This is especially true when the user is not looking directly at the beaker, for example, during rapid or routine tasks.

[0045] The line thickness T of the first marking lines can advantageously be in the range of 0.5 mm to 0.9 mm. A line thickness in this range ensures that the marking lines are clearly visible without cluttering the scale or impairing readability. The line thickness is thin enough to allow precise readings, yet thick enough to ensure the scale's durability.

[0046] In an advantageous embodiment, exactly one second horizontal marking line is arranged midway between each pair of adjacent first horizontal marking lines. Alternatively or additionally, it can be advantageously provided that every second marking line7

[0047] The clear placement of the second marker lines relative to the first has the distinct advantage that the user can quickly orient themselves without having to mentally calculate the relevant distances or relationships. This saves time and reduces errors.

[0048] Preferably, the top marking line of the scale is one of the first marking lines. This gives the scale a quickly and clearly comprehensible visual hierarchy, which supports fast and intuitive readability. In particular, it can be advantageous to designate the top marking line as indicating the nominal capacity of the beaker. This prominent design of the top marking line facilitates quick and intuitive identification of the maximum fill quantity without requiring the user to examine the scale in detail.

[0049] Similarly, it may be advantageous to provide that the lowest marking line of the scale is one of the first marking lines, which also supports the quick and intuitive readability of the scale.

[0050] In an advantageous embodiment, the scale has a vertical reference line. This vertical reference line serves as an aid to help the user align the beaker correctly when taking freehand readings. In particular, it is advantageous for the first and second marking lines to terminate at the vertical reference line, facilitating quick and intuitive orientation during reading. The first and second marking lines can be positioned to the right or left of the vertical reference line.A particularly advantageous design is one in which the first and second marking lines, together with the scale values ​​associated with the first and / or second marking lines, are arranged to the left of the vertical reference line, because this reduces the risk of the marking lines and scale values ​​being covered by the right hand (especially the thumb or base of the thumb of the user's right hand) when the user grasps the beaker with their right hand opposite the spout.

[0051] The beaker preferably has no handle. However, the presence of a handle is not entirely excluded.

[0052] Preferably, the scale has a scale value adjacent to each of the first marking lines, in particular horizontally next to each of the first marking lines, which corresponds to the fill level volume marked by the respective first marking line. Alternatively or additionally, the scale can have a scale value adjacent to each of the second marking lines, in particular horizontally next to each of the second marking lines, which corresponds to the fill level volume marked by the respective second marking line. A preferred embodiment is one in which the scale adjacent to each of the first marking lines,8

[0053] In particular, the scale has a numerical value next to each of the first marking lines, while the second marking lines have no numerical values. Such a design is particularly clear and intuitively easy for the user to read.

[0054] A particularly clear and intuitive design is one in which the scale, on the side of the first marking lines facing away from the reference line and adjacent to each of the first marking lines, especially horizontally next to each of the first marking lines, has a scale value corresponding to the fill level volume marked by the respective first marking line. Similarly, the scale can, alternatively or additionally, have a scale value on the side of the second marking lines facing away from the reference line and adjacent to each of the second marking lines, especially horizontally next to each of the second marking lines, corresponding to the fill level volume marked by the respective second marking line.

[0055] In an advantageous embodiment, the scale is white. The advantages of the particular design of the scale according to the invention, with first and second horizontal marking lines of different lengths and line thicknesses, are enhanced by the white scale. The combination of longer and thicker first marking lines and shorter and thinner second marking lines is clearly emphasized by the choice of white as the scale color and makes orientation easier for the user.

[0056] In a particularly advantageous embodiment, the scale is positioned entirely between a vertical reference meridian half-plane passing through the center of the spout and a vertical meridian half-plane that forms an angle of less than 130 degrees, particularly less than 110 degrees or less than 95 degrees, and most especially less than or equal to 90 degrees, with the vertical reference meridian half-plane. Such an embodiment has the advantage that the scale is located where the user can still see it even when gripping the beaker with their right hand opposite the spout. It has been observed that users almost always grip beakers with their right hand opposite the spout. The left hand is then available, for example, to measure a liquid, while the right hand holds the gripped beaker.

[0057] This design also has the advantage that the scale is not covered at all, or only minimally, by the user's right hand (especially the right thumb) when they grip the beaker with their right hand opposite the spout. Particularly with regard to this aspect, it is advantageous that the printed marking (preferably applied together with the scale) is located to the right of the scale.

[0058] is arranged in such a way that it is possible to position the scale particularly far to the left, so that the risk of covering it with the grasping hand (especially with the thumb and / or the base of the thumb of the grasping hand) is avoided or at least significantly reduced.

[0059] In particular, it may be advantageously provided that at least the reference line of the scale is arranged in a meridian half-plane which has an angle of less than 130 degrees, in particular less than 110 degrees or less than 95 degrees and most in particular less than or equal to 90 degrees or exactly 90 degrees, to the vertical reference meridian half-plane which passes through the center of the spout.

[0060] Particularly with regard to this aspect, it is advantageous that the imprint (preferably applied together with the scale) is placed to the right of the scale, which makes it possible to position the scale particularly far to the left, so that the risk of covering it with the grasping hand (especially with the thumb and / or the base of the thumb of the grasping hand) is avoided or at least significantly reduced.

[0061] It is particularly advantageous if the glass container has a wall thickness of 1.5 mm for a nominal capacity of 25 ml, or for a nominal capacity of 50 ml, or for a nominal capacity of 100 ml, or for a nominal capacity of 150 ml, or for a nominal capacity of 1.7 mm, or for a nominal capacity of 250 ml, or for a nominal capacity of 2000 ml, or for a nominal capacity of 400 ml, or for a nominal capacity of 600 ml, or for a nominal capacity of 800 ml, or for a nominal capacity of 2.2 mm, or for a nominal capacity of 1,000 ml, or for a nominal capacity of 2,000 ml has a wall thickness of 2.2 mm, or a nominal capacity of 3.The beaker has a wall thickness of 2.2 mm for a nominal capacity of 000 ml, 2.5 mm for a nominal capacity of 5000 ml, and 2.7 mm for a nominal capacity of 10000 ml. These designs are sufficiently stable while also allowing space for liquid within the beaker, ensuring that the fill level remains well below the top edge of the beaker and below the non-printable area.

[0062] It is also particularly advantageous if the glass container has a wall thickness of 3 mm for a nominal capacity of 25 ml, or a bottom thickness of 3 mm for a nominal capacity of 50 ml, or a bottom thickness of 3 mm for a nominal capacity of 100 ml, or a bottom thickness of 3 mm for a nominal capacity of 150 ml, or a 10

[0063] has a base thickness of 3 mm, or in the case of a nominal capacity of 400 ml, has a base thickness of 3 mm, or in the case of a nominal capacity of 600 ml, has a base thickness of 3.3 mm, or in the case of a nominal capacity of 800 ml, has a base thickness of 3.3 mm, or in the case of a nominal capacity of 1,000 ml, has a base thickness of 3.3 mm, or in the case of a nominal capacity of 2,000 ml, has a base thickness of 3.3 mm, or in the case of a nominal capacity of 3,000 ml, has a base thickness of 4 mm, or in the case of a nominal capacity of 5,000 ml, has a base thickness of 4 mm, or in the case of a nominal capacity of 10,000 ml, has a base thickness of 4.5 mm.These designs are sufficiently stable on the one hand and on the other hand leave space for liquid inside the beaker, which helps to ensure that the fill level of the nominal capacity is significantly below the upper edge of the beaker and below the non-printable area.

[0064] The method according to the invention is particularly suitable for the mass production of a large number of beakers, in which each beaker is manufactured in the manner of the invention. This means that all manufactured beakers have the above-mentioned outer diameters and heights and preferably the above-mentioned wall and base thicknesses, and therefore all beakers have a scale indicating the nominal capacity.

[0065] According to the independent inventive concept mentioned above, a beaker is particularly advantageous if it has at least one of the following aspects 1 to 20, and a method is particularly advantageous if it has at least one of the following aspects 21 to 23.

[0147] The invention is illustrated schematically and by way of example in the drawings and is described below with reference to the figures, whereby identical or similarly functioning elements are usually provided with the same reference numerals even in different embodiments. The figures show:

[0154] Fig. 7 shows the third embodiment in a top view, and

[0155] Fig. 8 shows an embodiment according to the prior art.18

[0156] Fig. 1 shows a schematic illustration of a prior art method for applying a scale 2 and an imprint 7 with further information to a glass container 1 by means of a single-stage screen printing process. In this process, the printing ink is applied to the glass container 1 by means of a fine-mesh screen printing fabric 20 stretched over a screen printing frame 21. Due to its cylindrical shape, the glass container 1 rolls on the screen printing frame 21 and the screen printing fabric 20. The glass container rotates about its central axis during this process. Sufficient axial clearance between the screen printing frame 21 and the radially projecting spout 13 is ensured by maintaining a sufficient axial distance between the screen printing frame 21 and the spout 13 during the rolling process.

[0157] This means that an annular cylindrical area 22, located axially directly below the spout 13 and shown in Figure 2, and the upper edge of the glass container 1 cannot be printed on. For beakers with the nominal dimensions specified in the relevant DIN standard, the fill level of the nominal capacity lies within this annular cylindrical area 22. Consequently, a scale 2 extending to the fill level of the nominal capacity cannot be printed using this screen printing process.

[0158] In the example shown in Figure 2, the nominal capacity is 3,000 ml. However, only a scale extending to 2,500 ml can be printed, as the fill level of the nominal capacity of 3,000 ml lies within the non-printable area 22.

[0159] Figure 3 shows a first embodiment of a beaker produced according to the inventive method in a side view.

[0160] The beaker has a glass container 1 on which a scale 2 is applied. The glass container 1 has a straight, circular cylindrical shape with vertical walls and features a radially outward-projecting, tapered spout 13 at its upper rim 12. The beaker has a nominal capacity of 3,000 ml, an outer diameter A of 156.0 mm, and a height H of 212.5 mm ± 1.5 mm.

[0161] Scale 2 has several first horizontal marking lines 3 with a length L and a line thickness T. A second horizontal marking line 4, with a length of 0.5L and a line thickness in the range of 0.6T to 0.8T, is arranged midway between each pair of adjacent first horizontal marking lines 3.

[0162] The uppermost of the marking lines on scale 2 is one of the first marking lines 3. It marks the nominal capacity (in this example 3,000 ml) of the beaker. The lowermost 19

[0163] The marking line of scale 2 is also one of the first marking lines 3.

[0164] The scale also features a vertical reference line 5, which serves as a vertical orientation aid to help the user to correctly align the beaker when reading freehand. The first marking lines 3 and second marking lines 4 are located to the left of the vertical reference line 5 and terminate at the vertical reference line 5.

[0165] Scale 2 has a scale value number 6 to the left of each of the first marking lines 3, which corresponds to the fill level volume marked by the respective first marking line 3.

[0166] The beaker has a printed number 7 to the right of scale 2, which includes the following printed elements:

[0167] • Indication of the nominal capacity 8,

[0168] • Indication of a brand name 9,

[0169] • Representation of a logo 10,

[0170] • Representation of a retrace code 14

[0171] • Labeling area writable with a writing instrument, especially a pencil 11.

[0172] Due to the design and arrangement of the scale, the beaker has the distinct advantage that the scale 2 (and especially the scale values ​​6) is not covered by the user's right hand 1 (not shown in this figure) when the user grasps the beaker with their right hand 19 opposite the spout. This allows the user to easily and precisely read the volume of the liquid while holding the beaker freely in their hand 19.

[0173] Figure 4 shows a schematic illustration of the arrangement of the screen frame 21 and the screen mesh 20 relative to the glass container 1 in the production of the first embodiment of a beaker according to the invention. The specific dimensions ensure that the height of the fill level of the nominal capacity 8 is below the height of the non-printable area, allowing a scale 2 to be printed where the uppermost marking line indicates the nominal capacity 8 of the beaker. The user of a beaker produced in this way therefore has the advantage of being able to precisely determine the fill level even when the beaker is filled with a liquid whose volume is, for example, in the range of 90% to 110% of the nominal capacity 8, since the uppermost marking line, which indicates the nominal capacity of the beaker, is available as a reference.

[0174] Figure 5 shows a second embodiment of a beaker produced according to the inventive method in a side view.

[0175] The beaker has a glass container 1 on which a scale 2 is applied. The glass container 1 has a straight, circular cylindrical shape with vertical walls and features a radially outward-projecting, tapered spout 13 at its upper rim 12. The beaker has a nominal capacity of 400 ml, an outer diameter A of 83.1 ± 1 mm, and a height H of 112.0 ± 1 mm.

[0176] Scale 2 has several first horizontal marking lines 3 with a length L and a line thickness T. A second horizontal marking line 4, with a length of 0.5L and a line thickness in the range of 0.6T to 0.8T, is arranged midway between each pair of adjacent first horizontal marking lines 3.

[0177] The uppermost marking line of scale 2 is one of the first marking lines of scale 3. It marks the nominal capacity (in this example, 400 ml) of the beaker. The lowermost marking line of scale 2 is also one of the first marking lines of scale 3.

[0178] The scale also features a vertical reference line 5, which serves as a vertical orientation aid to help the user to correctly align the beaker when reading freehand. The first marking lines 3 and second marking lines 4 are located to the right of the vertical reference line 5 and terminate at the vertical reference line 5.

[0179] The scale 2 has a scale value number 6 to the right of each of the first marking lines 3, which corresponds to the fill level volume marked by the respective first marking line 3.

[0180] The beaker has a printed number 7 to the left of scale 2, which includes the following printed elements:

[0181] • Indication of the nominal capacity 8,

[0182] • Indication of a brand name 9,

[0183] • Representation of a logo 10,

[0184] • Labeling area writable with a writing instrument, especially a pencil 11.

[0185] Figure 6 shows a third embodiment of a beaker produced according to the inventive method in a side view.

[0186] The beaker has a glass container 1 on which a scale 2 is applied. The21

[0187] Glass container 1 has a straight, circular cylindrical shape with vertical walls and features a radially outward-projecting and tapered spout 13 at its upper rim 12. The beaker has a nominal capacity of 600 ml, an outer diameter A of 93.5 ± 1 mm, and a height H of 127.0 ± 1 mm.

[0188] Scale 2 has several first horizontal marking lines 3 with a length L and a line thickness T. A second horizontal marking line 4, with a length of 0.5L and a line thickness in the range of 0.6T to 0.8T, is arranged midway between each pair of adjacent first horizontal marking lines 3.

[0189] The uppermost marking line of scale 2 is one of the first marking lines of scale 3. It marks the nominal capacity (in this example, 600 ml) of the beaker. The lowermost marking line of scale 2 is also one of the first marking lines of scale 3.

[0190] The scale also features a vertical reference line 5, which serves as a vertical orientation aid to help the user to correctly align the beaker when reading freehand. The first marking lines 3 and second marking lines 4 are located to the left of the vertical reference line 5 and terminate at the vertical reference line 5.

[0191] Scale 2 is positioned, with respect to the outer circumferential surface of the beaker, entirely between a vertical reference meridian half-plane 15, which passes through the center of the spout 13 and the central axis 16 of the beaker, and a vertical meridian half-plane 17, which forms an angle of less than 95 degrees with the vertical reference meridian half-plane, as shown in Figure 7. Scale 2 is shown schematically as a dashed line in Figure 4.

[0192] The reference line 5 of the scale 2 is arranged in another vertical meridian half-plane 18 with respect to the outer circumferential surface of the beaker, which has an angle of less than 95 degrees to the vertical reference meridian half-plane 15, as is also shown in Figure 7.

[0193] Scale 2 has a scale value number 6 to the left of each of the first marking lines 3, which corresponds to the fill level volume marked by the respective first marking line 3.

[0194] The beaker has a printed number 7 to the right of scale 2, which includes the following printed elements:

[0195] Nominal capacity stated as 8.22

[0196] • Indication of a brand name 9,

[0197] • Representation of a logo 10,

[0198] • Representation of a retrace code 14

[0199] • Labeling area writable with a writing instrument, especially a pencil 11.

[0200] As also illustrated in Figure 6, the beaker has the distinct advantage, due to the design and arrangement of the scale, that the scale 2 (and in particular the scale values ​​6) is not covered by the user's right hand 1 when the user grasps the beaker with their right hand 19 opposite the spout. This allows the user to easily and precisely read the volume of the liquid while holding the beaker freely in their hand 19.

[0201] Figure 8 shows a prior art embodiment comprising a scale 2 whose uppermost marking line does not indicate the nominal filling volume and which is located to the right of the imprint 7. The disadvantage of such an embodiment is that it is not possible to read the volume of a liquid filled up to the nominal capacity precisely, because the scale 2 does not extend to the nominal capacity and because its position is such that, with the user's usual grip, at least the upper part of the scale is covered by the thumb or the base of the thumb of the hand holding the beaker.23
