Technical Field of the I nvention

The invention subject matter of the application is related to a glass household object such as drinkwares, bottles and bowls that have rough surfaces which enable gradual bubbling and which is developed to regulate the amount of foam at liquid level, to regulate the formation rate of gas such as carbon dioxide and to regulate the bubble formation (bubbling) rate depending on the liquid level on contact surfaces of gaseous drinks with glass household objects.

Background of the I nvention ( Prior Art) During production of gaseous beverages, foaming on the beverage surface or bubbling in the beverage is a requested property. Bubble formation is also known as nucleation or bubbling. However, in the known state of the art, the foam forming on the surface of the gaseous beverages or the bubbles forming on the points where the beverage contacts the surface of the glass household object diminish in a short time.

I n the known state of the art, in order to make the bubble and/or foam formation constant, glass household glass objects having rough surfaces on base region are used. When the beverage contacts said regions, the gas such as carbon dioxide contained within emerges and bubbles are formed. I n some beverages, while formation of bubbles provides foam formation on liquid level, in others it only provides a visual quality. Since the rough surfaces are on the bottom (base) of the glass, while drinking; the beverage is continuously in contact with said surface, thus intense bubble formation continues due to emergence of gas such as carbon dioxide. As the amount of the beverage decreases, this situation may cause too much bubble formation relative to the amount of the drink, emergence of gas such as carbon dioxide and a change in the taste of the drink due to decreasing gas concentration. Brief Description of the I nvention

I n the glass household object of the invention, the rough surfaces that enables gradual bubbling in the beverage are not only limited to the base of the glass household object, but rough surfaces with different roughness rates or rough surface levels are included to internal side surfaces while the roughness on the base is decreased.

The goals while developing the glass household object of the invention are;

• Providing a controlled bubble formation and/or hence foam formation while the beverage is consumed, · Preserving the taste and visual quality of the beverage by holding the amount of foam on the liquid level at a certain level due to the decrement in the bubble formation as the amount of the beverage decreases,

• Distribution of rough surfaces to the internal side surfaces and the base of the glass household object in accordance with the volume of the beverage, · Providing visual properties to the beverage by creating rough surfaces on the internal side surfaces of the glass household object in the form of logo or labels.

Detailed Description of the I nvention

It is a glass household object ( 1 ) that is developed to enable bubble formation, i.e. bubbling on contact surfaces of the gaseous beverages with glass household objects (1 ) and it comprises rough surfaces (2) distributed on internal base surfaces (3) and on internal side surfaces (4) at different height levels in order to regulate the amount of bubbles in liquid level, to regulate the formation rate of gas such as carbon dioxide and to regulate the bubble formation rate depending on the liquid level. I n some beverages, while bubble formation causes foam accumulation on liquid level, in others it only provides a visual quality. Therefore, bubbling effect and amount and density of rough surface (2) application may change depending on the type of the beverage.

I n the glass household object ( 1 ) of the invention, the rough surfaces (2) on the base internal surfaces (3) are decreased and gradually distributed on the internal side surfaces (4) along the height of the glass household object ( 1 ) . Thus, when the liquid level goes under each level, the bubbling effect of the rough surface (2) on beverage is gradually decreased. Accordingly, the emergence rate of the gas such as carbon dioxide, bubble formation (bubbling) rate and/or foam formation rate in the beverage are decreased. I n the example shown in Figure 1 , the circular rough surfaces (2) are gradually distributed along the height of internal side surface (4) of the glass household object (1 ) . Moreover, there is a rough surface (2) on the base internal surface (3) . Thus, the bubbling effect provided by the glass household object (1 ) is also distributed over said surfaces (3 and 4) .

I n this example, rough surfaces (2) are shown as grouped in levels and the ratio of the rough surfaces (2) on base internal surfaces (3) is 30% . The ratio of the circular rough surfaces (2) gradually positioned depending on the height are 20% , 25% and 30% , respectively. These ratios may change in regions where the beverage volume changes depending on the geometrical shape of the glass household object ( 1 ) as well as depending on the gas concentration in the beverage to be consumed. When the liquid level goes below the rough surfaces (2) positioned on the internal side surfaces (4) , since the step above the liquid level has no contact with the liquid, the bubble formation effect is decreased.

The rough surfaces (2) positioned on the internal side surfaces (4) suggested in the invention can be in horizontal circular form as well as being positioned vertically as shown in Figure 4. Moreover, as the rough surfaces (2) can be formed linearly, they can also be positioned regionally. The rough surfaces (2) that are gradually distributed in groups when in linear form are distributed in regions when in logo or letter form ( Figure 2 or 3) . The number or regions of the rough surfaces (2) formed on internal side surfaces (4) in linear steps or regions and the number of rough surfaces (2) in the steps may change depending on the type of beverage and the form of the glass household object (1 ) . Furthermore, roughness depth, height and roughness density of the formed rough surfaces (2) may change depending on the type of the beverage and the geometric form of the glass household object ( 1 ) , similarly. The amount of rough surface (2) on the internal side surface (4) of the glass household object may change depending on the geometric form of the glass household object (1 ) and the properties of the beverage.

I n the case that the amount of the rough surface (2) is determined depending on the geometric form of the glass household object ( 1 ) , rough surfaces (2) are formed in proportion with the liquid volume changing along the height and bubble formation can be regulated. I n other words, the amount of used rough surfaces (2) can be increased depending on the volume increasing from the base to the top. Moreover, in the height levels where the diameter of the glass household object (1 ) is large, additional vertical rough surfaces (2) can be included as seen in Figure 4.

I n order to decrease the amount of rough surfaces (2) of which the beverage contacts as the amount of beverage in the glass household object ( 1 ) decreases, as circular gradual rough surfaces (2) can be used along the height levels of the glass household object ( 1 ) , the amount of rough surfaces (2) can be decreased by forming rough surfaces (2) in logo or letter form and thus a visual quality can be provided.

Circular, spiral and vertical rough surfaces have a linear characterization and rough surfaces (2) in logo or letter form has a regional characterization. I n the invention, it is possible to form rough surfaces (2) only on the internal side surfaces (4) of the glass household object ( 1 ) by removing the rough surfaces (2) on the base internal surface (3) of the glass household object (1 ) entirely.

I n the glass household object ( 1 ) that provides gradual bubble formation, the rough surfaces (2) ; can be formed by laser ablation or mechanical abrasion methods as well as being formed by paint engraving method. I n formation of rough surfaces (2) by abrasion, pits form on the surface. I n the engraving method, protrusions form on the surface. The depth and height of the pits and protrusions affect the bubbling effect and thus bubble formation. Moreover, the amount of pits/protrusions on a certain region (roughness density) may change the bubbling effect. The roughness density along with the depth and/or height can be changed depending on the geometric form of the glass household object (1 ) and the type of the beverage.

I n the case that the consumed beverage is a beverage containing gas such as carbon dioxide at high concentrations, in the glass household object (1 ) of the invention, the amount and density of the rough surfaces (2) must be decreased. Similarly, in the case that the gas concentration of the consumed beverage is low, in the glass household object ( 1 ) of the invention, the amount and density of the rough surfaces (2) must be increased.
