Description

[Technical Field]

[0001] This disclosure relates to a beverage container for holding beverages. [Background technology]

[0002] Patent Document 1 describes a pulp molded container used as a container for beverages such as coffee, tea, and juice, or for food products containing liquids such as soup and potage. The pulp molded container consists of a main body made of a pulp molded body and a resin layer that is non-adhesively housed inside the main body. A flange portion of a constant width is integrally formed around the entire circumference of the upper opening edge of the main body, projecting radially outward. After use, the resin layer is separated from the main body, and the main body is recycled as waste paper. [Prior art documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2012-77420 [Overview of the project] [Problems that the invention aims to solve]

[0004] The aforementioned pulp molded containers have a resin layer located inside the main body. Therefore, after use, the pulp molded container cannot be recycled unless the resin layer is separated. Thus, there is room for improvement in terms of recyclability. In beverage containers, condensation may occur on the outer surface of the container when a cold beverage is placed inside. When condensation occurs on the outer surface of a beverage container, hands or tables may get wet, so it is desirable to make it less likely for condensation to occur. Furthermore, beverage containers are required to suppress the rise in temperature of the beverage when a cold beverage is placed inside, and to provide a pleasant mouthfeel when the drinker consumes the beverage.

[0005] This disclosure aims to provide a beverage container that enhances recyclability and suppresses the rise in beverage temperature, resulting in a better mouthfeel. [Means for solving the problem]

[0006] (1) The beverage container relating to this disclosure is a beverage container for holding a beverage. The beverage container contains plant-derived residue, the plant-derived residue being malt feed and / or hop harvest. The beverage container comprises a body portion, which is the part that a drinker touches with their fingers to hold the beverage container, and a mouth portion, which is the part that a drinker puts their mouth to when drinking the beverage. The beverage container is made of pulp mold, and the density of the paper of the pulp mold is 0.3 (g / cm³). 3 ) greater than and 1.0 (g / cm³) 3 It is less than ).

[0007] This beverage container has a body that the drinker's fingers touch and a mouthpiece that the drinker's mouth touches, and is constructed from pulp mold. Therefore, because it does not have a resin layer, the beverage container itself can be recycled, thus increasing its recyclability. In this beverage container, the density of the pulp molded paper is 1.0 g / cm³. 3 It is less than 1.0 (g / cm³). 3 By having a density of less than 0.3 (g / cm³), the paper's breathability can be improved depending on its humidity control properties, thus preventing condensation from forming on the outer surface of the beverage container. In this beverage container, the density of the pulp molded paper is 0.3 (g / cm³). 3 It is greater than 0.5 (g / cm³). This allows for a higher density of beverage containers, thus suppressing the temperature rise of cold beverages. Furthermore, the density of pulp molded paper is 0.5 (g / cm³). 3 If it is larger than ), the surface of the beverage container can be made smoother, which can improve the mouthfeel when drinking the beverage.

[0008] (2) In the above (1), the beverage container has an inner surface that comes into contact with the beverage, and the arithmetic mean roughness Ra of the inner surface may be 6 (μm) or less. In this case, since the inner surface of the beverage container can be made smooth, the mouthfeel can be improved, and the pouring quality of the beverage poured into the beverage container can be enhanced.

[0009] (3) In the above (1) or (2), the beverage container has an outer surface facing the opposite side of the inner surface that comes into contact with the beverage, and the arithmetic mean roughness Ra of the outer surface may be 6 (μm) or less. In this case, since the outer surface of the beverage container can be made smooth, the appearance of the beverage container can be improved, and the cosmetic property and the sense of luxury of the beverage container can be enhanced.

[0010] (4) In any of the above (1) to (3), the density of the drinking mouth portion may be greater than the density of the body portion. In this case, due to the large density of the drinking mouth portion, while making the drinking mouth strong, the surface of the drinking mouth portion can be made smooth, so that the mouthfeel can be further improved.

Advantages of the Invention

[0011] According to the present disclosure, the recyclability can be enhanced, and the rise in the temperature of the beverage can be suppressed to improve the mouthfeel.

Brief Description of the Drawings

[0012] [Figure 1] FIG. 1 is a perspective view showing a beverage container according to an embodiment. [Figure 2] FIG. 2(a) is a plan view showing the beverage container of FIG. 1. FIG. 2(b) is a bottom view showing the beverage container of FIG. 1. [Figure 3] FIG. 3 is a cross-sectional view of the beverage container when cut along a plane extending in the vertical direction.

Modes for Carrying Out the Invention

[0013] The embodiments of the beverage container according to this disclosure will be described below with reference to the drawings. In the description of the drawings, the same or equivalent elements will be denoted by the same reference numerals, and redundant explanations will be omitted as appropriate. For the sake of ease of understanding, some parts of the drawings may be simplified or exaggerated, and the dimensional ratios, etc., are not limited to those shown in the drawings.

[0014] In this disclosure, “beverage” means a drinkable liquid. “Beverage” includes alcoholic beverages such as beer, sparkling wine, shochu cocktails, and wine, as well as non-alcoholic carbonated beverages and soft drinks. “Beverage” is, for example, a sparkling beverage. “Sparkling beverage” is, for example, a fermented alcoholic beverage containing gas such as carbon dioxide, and has foaming properties in which a layer of foam is formed on the liquid when poured into a beverage container, and foam retention properties in which the formed foam is maintained for a certain period of time or longer.

[0015] A carbonated beverage is, for example, a beer-flavored beverage. A beer-flavored beverage means a beverage that has the flavor and aroma of beer. Examples of beer-flavored beverages are not limited to these, but include, for example, those classified as beer, sparkling alcoholic beverages, and other carbonated alcoholic beverages as defined in Article 3 of the Liquor Tax Act (Law No. 6 of 1953). In addition, beverages that do not belong to the carbonated alcoholic beverages under the Liquor Tax Act and soft drinks (for example, non-alcoholic beer-flavored beverages) can also be called beer-flavored beverages. However, the beer-flavored beverages according to this embodiment are not limited to those exemplified above.

[0016] A "beverage container" is a container that holds a beverage. An example of a "beverage container" is a glass capable of holding a beverage. "Drinking" refers to a person consuming the beverage, and "drinker" refers to the person drinking. The following example will describe a case where the beverage is beer and the beverage container is a glass.

[0017] Figure 1 is a perspective view showing an example of a beverage container 1. For example, beverage container 1 is a disposable cup. Beverage container 1 is made of reusable materials. Beverage container 1 is made of pulp mold. Beverage container 1 is made of paper. For example, beverage container 1 does not contain resin.

[0018] In other words, beverage container 1 does not have any parts made of resin. In this case, it is possible to eliminate resin waste, thus contributing to Sustainable Development Goal (SDG) 12, "Ensure sustainable consumption and production patterns." Furthermore, since it becomes possible to eliminate the need for resin and reduce plastic waste, it contributes to Sustainable Development Goal (SDG) 14, "Conserve and sustainably use the oceans, seas and marine resources."

[0019] In this embodiment, paper is a concept that does not include resin. For example, if the beverage container 1 is made only of paper, the separation of resin during recycling becomes unnecessary, and the beverage container 1 can be easily recycled. Therefore, recyclability can be improved.

[0020] The beverage container 1 is made of pulp. A beverage container 1 made of pulp can be made of a more environmentally friendly material compared to beverage containers made of resin or the like. Furthermore, a beverage container 1 made of pulp can be made lighter than a beverage container made of glass or the like, making it easier to hold in the hand.

[0021] For example, the beverage container 1 may be made of virgin pulp. Virgin pulp is pulp that does not contain recycled paper. The beverage container 1 may contain, for example, plant-derived residues. Examples of plant-derived residues include malt feed, bagasse, hop harvest residues, lemon harvest residues, etc. The plant-derived residues may also be malt feed and / or hop harvest products. Malt feed is spent beer produced during the manufacturing of beer, and is the spent malt obtained during brewing. By including malt feed as a material for the beverage container 1, spent malt generated at a beer factory, for example, can be effectively utilized.

[0022] For example, the beverage container 1 is placed on a surface with its mouthpiece 3 facing upwards. The surface on which the beverage container 1 is placed is, for example, the top surface of a table. The height of the beverage container 1 (the vertical length of the beverage container 1 when it is placed on the surface) is 5 cm or more and 20 cm or less. For example, the width of the beverage container 1 (the horizontal length of the beverage container 1 when it is placed on the surface) increases towards the top.

[0023] The beverage container 1 comprises a body portion 2, which is the part that the drinker touches with their fingers to hold the beverage container 1, and a mouthpiece portion 3, which is the part that the drinker puts their mouth to when drinking the beverage. For example, the beverage container 1 has an upper portion 4 located between the body portion 2 and the mouthpiece portion 3, and a stepped portion 5 located between the upper portion 4 and the body portion 2, which is inclined relative to both the upper portion 4 and the body portion 2. The mouthpiece portion 3, the upper portion 4, the stepped portion 5, and the body portion 2 are arranged in this order from the top end downwards of the beverage container 1.

[0024] Figure 2(a) is a plan view of the beverage container 1. Figure 2(b) is a bottom view of the beverage container 1. As shown in Figures 1, 2(a), and 2(b), the beverage container 1 is a bottomed cylindrical shape. That is, in plan view, the beverage container 1 is circular in shape. For example, the minimum outer diameter of the body portion 2 in plan view is smaller than the minimum outer diameter of the stepped portion 5 in plan view. For example, the minimum outer diameter of the stepped portion 5 in plan view is smaller than the minimum outer diameter of the upper portion 4 in plan view. For example, the minimum outer diameter of the upper portion 4 in plan view is smaller than the minimum outer diameter of the drinking spout portion 3 in plan view. For example, in the beverage container 1, the outer diameter of the beverage container 1 increases from the bottom end upwards.

[0025] For example, the vertical length of the body 2 (the vertical direction when the beverage container 1 is placed on the mounting surface) is 50% or more and 70% or less of the height of the beverage container 1. For example, the width of the body 2 increases towards the top. For example, in a plan view, the body 2 is circular in shape. The outer diameter of the body 2 increases towards the top. For example, the maximum outer diameter of the body 2 is 5 cm or more and 10 cm or less, and the minimum outer diameter of the body 2 is 3 cm or more and 7 cm or less.

[0026] For example, the vertical length of the stepped portion 5 is 2% or more and 10% or less of the height of the beverage container 1. For example, the width of the stepped portion 5 increases as it goes upwards. For example, in a plan view, the stepped portion 5 is circular in shape. The outer diameter of the stepped portion 5 increases as it goes upwards.

[0027] The stepped portion 5 includes, for example, a lower stepped portion 5b extending upward from the body portion 2, and an upper stepped portion 5c located between the lower stepped portion 5b and the upper portion 4. For example, in a side view (when the beverage container 1 placed on a surface is viewed horizontally), the lower stepped portion 5b is recessed towards the center in the width direction (left-right direction in Figure 1, etc.) of the beverage container 1, and the upper stepped portion 5c protrudes outward in the width direction of the beverage container 1. The lower stepped portion 5b is curved so as to be recessed towards the center in the width direction of the beverage container 1, and the upper stepped portion 5c is curved so as to protrude outward in the width direction of the beverage container 1. For example, the portion between the lower stepped portion 5b and the upper stepped portion 5c is the portion where the curvature of the stepped portion 5 changes.

[0028] For example, the vertical length of the upper part 4 is 10% or more and 30% or less of the height of the beverage container 1. For example, the width of the upper part 4 increases towards the top. For example, in a plan view, the upper part 4 is circular in shape. The outer diameter of the upper part 4 increases towards the top. For example, the maximum outer diameter of the upper part 4 is 6 cm or more and 12 cm or less, and the minimum outer diameter of the upper part 4 is 5 cm or more and 10 cm or less.

[0029] The drinking spout 3 constitutes the upper end of the beverage container 1. For example, the vertical length of the drinking spout 3 is 2% or more and 10% or less of the height of the beverage container 1. For example, the width of the drinking spout 3 increases towards the top. For example, in a plan view, the drinking spout 3 is circular in shape. The outer diameter of the drinking spout 3 increases towards the top.

[0030] The drinking spout 3 includes, for example, a lower drinking spout 3b extending upward from the upper part 4, and an upper drinking spout 3c extending from the lower drinking spout 3b to the upper end of the beverage container 1. For example, in a side view, the lower drinking spout 3b is recessed towards the center in the width direction of the beverage container 1, and the upper drinking spout 3c extends in a straight line. In this case, the lower drinking spout 3b is a curved surface, and the upper drinking spout 3c is a flat surface. Note that the drinking spout 3 does not necessarily include both the lower drinking spout 3b and the upper drinking spout 3c, and may consist of only one of them.

[0031] For example, in a side view, the body 2, upper part 4, and drinking spout 3 (upper drinking spout 3c) are straight. The body 2, upper part 4, and drinking spout 3 are inclined with respect to the vertical such that their area in a plan view increases as they extend upward. That is, the body 2, upper part 4, and drinking spout 3 are inclined with respect to the vertical such that the width of the beverage container 1 increases as it extends upward.

[0032] For example, the angle of inclination of the fuselage 2 with respect to the vertical is greater than the angle of inclination of the upper part 4 with respect to the vertical. However, the angle of inclination of the fuselage 2 with respect to the vertical may be less than the angle of inclination of the upper part 4 with respect to the vertical. As an example, the angle of inclination of the fuselage 2 with respect to the vertical is 10° or more and 30° or less, and the angle of inclination of the upper part 4 with respect to the vertical is 5° or more and 25° or less.

[0033] The angle of inclination of the drinking spout 3 with respect to the vertical is, for example, greater than the angle of inclination of the body 2 with respect to the vertical, and greater than the angle of inclination of the upper part 4 with respect to the vertical. For example, the angle of inclination of the drinking spout 3 with respect to the vertical is 25° or more and 35° or less. In this case, because the drinking spout 3 is moderately inclined with respect to the vertical, the base of the drinking spout 3 can be made the same thickness as the body 2, while maintaining the strength of the drinking spout 3, and the tip of the drinking spout 3 can be made thinner. Furthermore, by providing strength to the base of the drinking spout 3, the beverage container 1 can be easily removed from the mold.

[0034] The beverage container 1 has a bottom surface 6 that faces downwards. When the beverage container 1 is placed on a surface, at least a portion of the bottom surface 6 contacts the surface. The bottom surface 6 has, for example, the marks of the wire mesh used during the molding of the beverage container 1. In this case, the bottom surface 6 is rougher than the other surfaces of the beverage container 1.

[0035] The bottom surface 6 includes, for example, a contact surface 6b that contacts the placement surface, and a curved surface 6c that curves obliquely upward from the outer periphery of the contact surface 6b in a plan view. As an example, the trace of the wire mesh is formed on the contact surface 6b. For example, the area of the contact surface 6b is 1000 (mm 2 ) or more and 20000 (mm 2 ) or less. The contact surface 6b is a flat surface, and the curved surface 6c is curved so as to bulge obliquely downward. For example, in a plan view, the contact surface 6b is circular, and the curved surface 6c is annular surrounding the contact surface 6b.

[0036] FIG. 3 is a cross-sectional view when the beverage container 1 is cut by a plane that includes the center of the beverage container 1 in a plan view and extends in the vertical direction. As shown in FIG. 3, the beverage container 1 has an inner surface 7 that contacts the beverage and an outer surface 8 that faces the opposite side of the inner surface 7. The inner surface 7 is formed inside the drinking mouth portion 3, the upper portion 4, the step portion 5, the body portion 2, and the bottom surface 6.

[0037] The area of the inner surface 7 is, for example, 25000 (mm 2 ) or more and 30000 (mm 2 ) or less. For example, the arithmetic mean roughness Ra of the inner surface 7 is 6 (μm) or less. The arithmetic mean roughness Ra of the inner surface 7 is smaller than the arithmetic mean roughness Ra of the bottom surface 6. For example, the arithmetic mean roughness Ra of the inner surface 7 may be 1 (μm) or more, 2 (μm) or more, or 3 (μm) or more. The arithmetic mean roughness of the inner surface 7 may be 5 (μm) or less, or 4 (μm) or less.

[0038] The area of the outer surface 8 is larger than the area of the inner surface 7. For example, the area of the outer surface 8 is 25000 (mm 2 ) or more and 30000 (mm 2 ) or less. For example, the outer surface 8 is formed outside the drinking mouth portion 3, the upper portion 4, the step portion 5, and the body portion 2. The arithmetic mean roughness Ra of the outer surface 8 is, for example, the same as the arithmetic mean roughness Ra of the inner surface 7. In this case, the arithmetic mean roughness Ra of the outer surface 8 is 6 (μm) or less. However, the arithmetic mean roughness Ra of the outer surface 8 may be different from the arithmetic mean roughness of the inner surface 7.

[0039] Next, the thickness of each part of the beverage container 1 will be described. The thickness of the drinking spout 3 is thinner than the thickness of the body 2. The thickness of the drinking spout 3 may also be thinner than the thickness of the parts of the beverage container 1 other than the drinking spout 3. For example, the thickness of the drinking spout 3 is 0.5 mm or more and 1.5 mm or less (0.6 mm as an example). The thickness of the drinking spout 3 may also be 1.0 mm or less, 0.9 mm or less, 0.8 mm or less, or 0.7 mm or less. The thickness of the drinking spout 3 may also be 0.55 mm or more and 0.65 mm or less.

[0040] The thickness of the upper part 4 is greater than the thickness of the drinking rim 3. The thickness of the upper part 4 is, for example, the same as the thickness of the stepped part 5. Alternatively, the thickness of the upper part 4 may be the same as the thickness of the body part 2. For example, the thickness of the upper part 4 is greater than the thickness of the bottom surface 6. For example, the thickness of the upper part 4 is 0.7 mm or more and 1.2 mm or less (0.8 mm as an example). The thickness of the upper part 4 may be 1.1 mm or less, 1.0 mm or less, or 0.9 mm or less. The thickness of the upper part 4 may be 0.75 mm or more and 0.85 mm or less.

[0041] For example, the thickness of the stepped portion 5 and the body portion 2 are the same as the thickness of the upper portion 4. The thickness of the bottom surface 6 is, for example, thinner than the thickness of the upper portion 4, the stepped portion 5, and the body portion 2. The thickness of the bottom surface 6 may be the same as the thickness of the drinking spout portion 3. In this case, the thickness of the bottom surface 6 is, for example, 0.5 mm or more and 1.0 mm or less (0.6 mm as an example).

[0042] The density of the pulp mold paper in beverage container 1 is 0.3 g / cm³. 3 ) greater than and 1.0 (g / cm³) 3 It is less than 0.4 (g / cm³). 3 ) or more, or 0.5 (g / cm³) 3 The density may be 0.9 (g / cm³). 3 ) or less, 0.8(g / cm 3 ) or less, 0.7(g / cm 3 ) or less, or 0.6 (g / cm³) 3 The following are also acceptable:

[0043] For example, the density of the drinking spout 3 is greater than the density of the body 2. The density of the drinking spout 3 may also be greater than the density of the parts of the beverage container 1 other than the drinking spout 3. For example, the density of the drinking spout 3 is 0.4 g / cm³. 3 ) or more, and 1.0 (g / cm³) 3 ) less than (for example, 0.7 (g / cm³) 3 The density of the drinking spout 3 is 0.5 (g / cm³). 3 ) or more, or 0.6 (g / cm³) 3 It may be 0.9 g / cm³ or more. The density of the drinking spout 3 is 0.9 g / cm³. 3 ) or less, or 0.8 (g / cm³) 3 The following are also acceptable:

[0044] The density of the upper part 4 is, for example, less than the density of the drinking spout 3. The density of the upper part 4 is, for example, the same as the density of the stepped part 5. The density of the upper part 4 may also be the same as the density of the body part 2. For example, the density of the upper part 4 is 0.3 g / cm³. 3 ) greater than and 0.9 (g / cm³) 3 ) or less (for example, 0.52 (g / cm³) 3 The density of the upper 4 is 0.4 (g / cm³). 3 ) or more, or 0.5 (g / cm³) 3 It may be ) or more. The density of the upper 4 is 0.8 (g / cm³). 3 ) or less, 0.7(g / cm 3 ) or less, or 0.6 (g / cm³) 3 The following are also acceptable:

[0045] For example, the density of the stepped portion 5 and the density of the body portion 2 are the same as the density of the upper portion 4. The density of the bottom surface 6 is greater than, for example, the density of the upper portion 4, the density of the stepped portion 5, and the density of the body portion 2. The density of the bottom surface 6 may be the same as the density of the drinking spout portion 3. In this case, the density of the bottom surface 6 is 0.4 g / cm³. 3 ) or more, and 1.0 (g / cm³) 3 ) less than (for example, 0.7 (g / cm³) 3 )) is.

[0046] Next, an example of a manufacturing method for beverage container 1 will be described. Beverage container 1 is manufactured using a drainage mold and a molding die. The molding die for beverage container 1 is made of metal (e.g., aluminum or iron). The drainage mold has holes formed in it. First, a mesh made of metal (e.g., stainless steel) is placed over the drainage mold. Next, the molding die is placed into the raw material (pulp dissolved in water). After the drainage mold is placed in the raw material, moisture from the raw material is drawn into the holes in the drainage mold. At this time, paper fibers contained in the raw material adhere to the wire mesh of the drainage mold. The paper fibers are transferred from the drainage mold to the molding die and molded by heat drying.

[0047] Next, the beverage container 1 is removed from the molding die. This concludes the explanation of an example of a method for manufacturing a beverage container 1. However, the steps and molding die for manufacturing the beverage container 1 are not limited to the above example and can be modified as appropriate.

[0048] Next, the effects obtained from the beverage container 1 according to this embodiment will be described. The beverage container 1 has a body portion 2, which is the part that the drinker's fingers touch, and a drinking spout portion 3, to which the drinker's mouth is placed. The thickness of the drinking spout portion 3 is thinner than the thickness of the body portion 2. Therefore, the discomfort when the mouth comes into contact with the drinking spout portion 3 can be reduced, making it easier to drink and more enjoyable. The beverage container 1 is made of pulp mold. Therefore, since it does not have a resin layer, the beverage container 1 itself can be recycled, thus increasing its recyclability.

[0049] In this embodiment, the drinking spout 3 is inclined with respect to the vertical direction such that the area of ​​the drinking spout 3 in a plan view increases as it extends upward. In this case, since the drinking spout 3 is inclined to widen as it extends upward, the mouthfeel of the drinking spout 3 can be further improved.

[0050] In this embodiment, the beverage container 1 comprises an upper part 4 located between the body part 2 and the drinking spout part 3, and a stepped part 5 located between the upper part 4 and the body part 2, which is inclined relative to both the upper part 4 and the body part 2. In this case, the beverage container 1 has a stepped part 5 between the upper part 4 and the body part 2, making it easier to hold the beverage container 1 by placing fingers on the stepped part 5. The stepped part 5, which is inclined relative to both the upper part 4 and the body part 2, makes it easier to remove the molding die used during molding, thus making it easier to manufacture the beverage container 1. Furthermore, when multiple beverage containers 1 are stacked, it becomes easier to separate each beverage container 1 from the multiple beverage containers 1.

[0051] In the beverage container 1 according to this embodiment, the density of the pulp molded paper is 1.0 g / cm³. 3 It is less than 1.0 (g / cm³). 3 By having a density of less than 0.3 (g / cm³), the paper's breathability can be improved, thus preventing condensation from forming on the outer surface 8 of the beverage container 1. In the beverage container 1, the density of the pulp molded paper is 0.3 (g / cm³). 3 It is greater than 0.5 (g / cm³). This allows the density of beverage container 1 to be increased, thereby suppressing the rise in temperature of cold beverages. Furthermore, the density of the pulp molded paper is 0.5 (g / cm³). 3 If it is larger than ), the inner surface 7 and outer surface 8 of the beverage container 1 can be made smooth, thus improving the mouthfeel when drinking the beverage.

[0052] In this embodiment, the beverage container 1 has an inner surface 7 that comes into contact with the beverage, and the arithmetic mean roughness Ra of the inner surface 7 is 6 (μm) or less. In this case, the inner surface 7 of the beverage container 1 can be made smooth, which improves the mouthfeel and enhances the quality of the beverage poured into the beverage container 1.

[0053] In this embodiment, the beverage container 1 has an outer surface 8 facing away from the inner surface 7 that comes into contact with the beverage, and the arithmetic mean roughness Ra of the outer surface 8 is 6 (μm) or less. In this case, the outer surface 8 of the beverage container 1 can be made smooth, which improves the appearance of the beverage container 1 and enhances its aesthetic appeal and sense of luxury.

[0054] In this embodiment, the beverage container 1 has a bottom surface 6 that faces downward, and the bottom surface 6 has the marks of the wire mesh used when the beverage container 1 was molded. In this case, by having the marks of the wire mesh on the bottom surface 6, it is possible to prevent the marks of the wire mesh from being formed on any part of the beverage container 1 other than the bottom surface 6. That is, the marks of the wire mesh are formed only on the bottom surface 6 that faces downward, and the marks of the wire mesh are not formed on the drinking spout 3 and the body 2. Therefore, since the marks of the wire mesh are formed only on the bottom surface 6 that faces downward and is hidden, the drinking spout 3 and the body 2 can be made smooth, and the aesthetic appeal of the beverage container 1 can be further enhanced.

[0055] In this embodiment, the density of the drinking spout portion 3 is greater than the density of the body portion 2. In this case, the higher density of the drinking spout portion 3 makes the drinking spout portion 3 stronger while also making its surface smoother, thus further improving the mouthfeel.

[0056] The embodiments of the beverage container relating to this disclosure have been described above. However, the beverage container relating to this disclosure is not limited to the embodiments described above, and may be modified within the scope of the gist described in the claims. That is, the shape, size, thickness, inclination, density, material, number, and arrangement of each part of the beverage container can be appropriately changed within the scope of the gist described above.
