Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the container disclosed in Patent Document 1, since the unevenness is formed only at the bottom, the stirring effect of the liquid inside is insufficient, and in order to uniformly diffuse and elute powders, granules, etc. into the liquid, it was necessary to increase the number of times of rotating the container.

[0005] The problem to be solved by the present invention is to provide a beverage container that can efficiently stir the liquid without using a stirring rod or a spoon when eluting powders, granules, etc. into the liquid.

Means for Solving the Problems

[0006] The beverage container of the present invention comprises a cylindrical body with an open top and a closed bottom, and a projection that protrudes radially from the inner wall of the body and is curved in an arc shape so as to be convex along the circumferential direction of the body from a base point at a predetermined height position of the body toward the end point of the bottom. The tip of the circumferential protrusion of the projection that is convex in the circumferential direction of the main body is formed at a position higher than the bottom. It is characterized by the following.

[0007] The projection is characterized in that it protrudes so as to be inclined toward the circumferential direction of the main body with respect to a normal line from the inner wall of the main body toward the axis, and when it is convex along one circumferential direction of the main body, it protrudes so as to be inclined toward one circumferential direction of the main body.

[0008] The projection has a first inclined surface on the side with a larger area and a second inclined surface on the side with a smaller area, and the inclination angle of the second inclined surface with respect to the inner wall of the main body is in the range of 40 to 100 degrees.

[0009] The projection is characterized in that it protrudes such that the horizontal distance between the projection and the axis gradually decreases from the base point to the endpoint. [Effects of the Invention]

[0010] According to the beverage container of the present invention, by rotating the beverage container containing liquid in a horizontal circular motion, the liquid inside is effectively stirred, so powders, granules, etc., can be easily dissolved into the liquid without using a stirring rod or the like.

[Figure 11] This is a cross-sectional view of a beverage container according to a second modified example of the present invention, along the DD line. [Modes for carrying out the invention]

[0012] The beverage container according to the present invention will be described below with reference to Figures 1 to 11. In Figures 1, 6, 8, and 10, the internal and back shapes, which are not visible from the outside, are shown with dashed lines.

[0013] First, a beverage container 1 according to the first embodiment of the present invention will be described with reference to Figures 1 to 5. As shown in Figures 1 and 2, the beverage container 1 is cylindrical and consists of a bottomed main body 2 with an open top. A projection 7 extends radially from the inner wall 3 of the main body 2 from a base point 5 at a predetermined height position of the main body 2 toward an endpoint 6 at the bottom 4, and is curved in an arc shape so as to be convex along the circumferential direction of the main body 2.

[0014] Figure 3 is a cross-sectional view of the main body 2 along the line A-A in Figure 1. When a virtual inner wall auxiliary line 9 shown by a dashed line is assumed so that the inner wall 3 forms a circumference at the portion where the protrusion 7 is formed, the protrusion 7 protrudes so as to incline in the circumferential direction of the main body 2 with respect to the normal line 11 shown by a dashed-dotted line from the center point 10 of the inner wall auxiliary line 9 toward the axis 8, and is arc-shapedly curved so that the protrusion 7 protrudes convexly along the circumferential direction of the main body 2. By the protrusion 7 inclining in the circumferential direction of the main body 2, the protrusion 7 forms a first inclined surface 12 on the wider side and a second inclined surface 13 on the narrower side.

[0015] Figure 4 is also a cross-sectional view of the main body 2 along the line A-A in Figure 1. When the intersection point of the second inclined surface 13 and the inner wall 3 of the main body 2 is taken as the intersection point 14 and the tangent line shown by a chain double-dashed line in the circumferential direction passing through the intersection point 14 is taken as the inner wall tangent line 15, the inclination angle 16 of the second inclined surface 13 with respect to the inner wall tangent line 15, that is, the inner wall 3, is set to be in the range of 40 degrees to 100 degrees.

[0016] Also, in the first embodiment, as shown in Figure 5, the protrusion 7 protrudes such that the horizontal distance between the protrusion 7 and the axis 8 gradually decreases from the base point 5 to the end point 6.

[0017] Due to the structural features shown above, as shown in Figure 5, when the beverage container 1 is swung in the swinging direction 17 so as to draw a clockwise circle, the liquid inside the beverage container 1 is stirred by receiving the pressure of the second inclined surface 13 of the protrusion 7, so that a clockwise liquid flow 18 can be efficiently generated.

[0018] Also, since the protrusion 7 is arc-shapedly curved so as to protrude convexly in the circumferential direction, while the liquid inside the beverage container 1 receives the pressure of the second inclined surface 13 of the protrusion 7, the liquid existing in the lower part closer to the bottom 4 than the tip of the circumferential convex part of the protrusion 7 that protrudes convexly in the circumferential direction of the main body 2 is sandwiched between the inner wall 3 and the second inclined surface 13 and a flow is generated that is drawn into the direction of the bottom 4, and is stirred when hitting the bottom 4, so that powders, granules, etc. sinking to the bottom 4 can be efficiently dissolved in the liquid.

[0019] Here, if the inclination angle 16 of the second inclined surface 13 is less than 40 degrees, the height of the projection 7 from the inner wall 3 decreases, so the pressure on the liquid due to the second inclined surface 13 decreases. Furthermore, the passage sandwiched between the inner wall 3 and the second inclined surface 13 becomes narrower, and the amount of liquid drawn towards the bottom 4 decreases, thus reducing the stirring effect. Also, if the inclination angle 16 is greater than 100 degrees, the liquid is more likely to flow over the projection 7, so the flow drawn towards the bottom 4 weakens, and the stirring effect decreases.

[0020] Furthermore, since the projection 7 is formed such that the horizontal distance between the projection 7 and the axis 8 gradually decreases from the base point 5 to the endpoint 6, the second inclined surface 13 of the projection 7 widens as it approaches the bottom 4. As a result, the liquid is stirred more strongly closer to the bottom 4, allowing powders and granules to be dissolved into the liquid with fewer oscillations, and enabling the dissolution of viscous particulate matter, which was difficult with conventional techniques.

[0021] Next, a beverage container 21 according to the second embodiment of the present invention will be described with reference to Figures 6 and 7. In the beverage container 21, as shown in Figure 6, a projection 27 that protrudes radially from the inner wall 23 of the main body 22 from a base point 25 at a predetermined height position of the main body 22 toward an endpoint 26 at the bottom 24 is curved in an arc shape so as to be convex along the circumferential direction of the main body 22, with the circumferential direction being opposite to that of the first embodiment.

[0022] Figure 7 is a cross-sectional view of the main body 22 along line BB in Figure 6. When an inner wall auxiliary line 29, shown as a dashed line, is imagined in the portion where the projection 27 is formed, the projection 27 protrudes inclined toward the circumferential direction with respect to the normal line 31, shown as a dashed line, which extends from the center point 30 of the inner wall auxiliary line 29 toward the axis 28, so that the projection 27 is curved in an arc along the circumferential direction of the main body 22 and becomes convex. By inclining the projection 27 toward the circumferential direction of the main body 22, the projection 27 forms a first inclined surface 32 on the side with a larger area and a second inclined surface 33 on the side with a smaller area.

[0023] In Figure 7, the point where the second inclined surface 33 and the inner wall 23 of the main body 22 intersect is defined as the intersection point 34, and the tangent line shown by the dashed line passing through the intersection point 34 in the circumferential direction is defined as the inner wall tangent line 35. In this case, the inclination angle 36 of the second inclined surface 33 with respect to the inner wall tangent line 35, i.e., the inner wall 23, is set to be in the range of 40 to 100 degrees.

[0024] In the second embodiment, by oscillating the beverage container 21 in a counterclockwise circular motion, the liquid inside the beverage container 21 is agitated by the pressure of the second inclined surface 33 of the projection 27, efficiently generating a counterclockwise liquid flow. A portion of this flow is drawn towards the bottom 24 and agitated, thus efficiently dissolving powders, granules, etc., that have settled at the bottom 24 into the liquid.

[0025] Next, a beverage container 41 according to a first modification of the first embodiment of the present invention will be described with reference to Figures 8 and 9. In the beverage container 41, as shown in Figure 8, a projection 47 that protrudes radially from the inner wall 43 of the main body 42 from a base point 45 at a predetermined height position of the main body 42 toward an endpoint 46 at the bottom 44 is formed in an arc shape so as to be convex along the circumferential direction of the main body 42, and the internal structure of the container is the same as in the first embodiment.

[0026] Figure 9 is a cross-sectional view of the main body portion 42 along the CC line in Figure 8. In the first modified example, no recess is formed on the outer surface of the main body portion 42, so the beverage container 41 can be gripped comfortably at any height position of the main body portion 42.

[0027] Next, a beverage container 61 according to a second modification of the first embodiment of the present invention will be described with reference to Figures 10 and 11. The second modification is made of ceramic, and in the beverage container 61, as shown in Figure 10, the main body 62 is narrowed at both the opening and the bottom 64 height positions, and a projection 67 that protrudes radially from the inner wall 63 of the main body 62 from a base point 65 at a predetermined height position of the main body 62 toward an endpoint 66 at the bottom 64 is curved in an arc shape so as to be convex along the circumferential direction of the main body 62.

[0028] In the second modified example, since the main body 62 is egg-shaped, even when the beverage container 61 is swung in a clockwise circular motion, it has the effect of preventing the liquid inside from overflowing from the opening.

[0029] Figure 11 is a cross-sectional view of the main body 62 along the DD line in Figure 10. Because it is made of ceramic, the apex of the projection 67 and the base of the projection 67 and the inner wall 63 have a rounded shape.

[0030] Furthermore, the number of protrusions formed inside the beverage container is not limited to one; multiple protrusions may be formed. The material of the beverage container can be plastic, glass, metal, ceramics, etc., but is not limited to these. Also, the shape of the main body is not limited to each embodiment.
