Beverage container having circular arcs

1. A beverage container for storing a product under positive pressure, comprising:

a body portion having an outer wall made of plastic, the body portion having a symmetrical cross-sectional shape formed by a plurality of circular arcs, each of the plurality of circular arcs having a center of curvature located inwardly relative to the container, the centers being spaced apart from one another, the body portion being recessed from other portions of the beverage container,

a maximum circumferential portion having an outer wall made of plastic, the maximum circumferential portion having a symmetrical cross-sectional shape, the maximum circumferential portion providing the maximum width and depth of the beverage container, the maximum circumferential portion including a band-shaped portion that extends parallel to a central vertical axis of the container, the maximum circumferential portion including a first maximum circumferential portion and a second maximum circumferential portion,

a shoulder portion adjacent to the first maximum circumferential portion located above the body portion, and

a bottom portion adjacent to the second maximum circumferential portion located below the body portion,

wherein, at least part of the shoulder portion and the bottom portion has the same cross-sectional shape as the body portion.

2. The beverage container of claim 1 , wherein each of the plurality of circular arcs has a same radius of curvature.

3. The beverage container of claim 2 , wherein the body portion has the cross-sectional shape formed by two, three, four, five, or six circular arcs, and further comprising depressed portions between the circular arcs.

4. The beverage container of claim 3 , wherein the depressed portions are configured to be held by fingers, and one, two, or three of the circular arcs are fit between the fingers holding the depressed portions.

5. The beverage container of claim 2 , wherein the body portion has the cross-sectional shape entirely or partially, and the first maximum circumferential portion is located above the body portion and the second maximum circumferential portion is located below the body portion.

6. The beverage container of claim 5 , wherein the first maximum circumferential portion and the second maximum circumferential portion have the same cross-sectional shape as the body portion.

7. The beverage container of claim 2 , wherein the body portion has the same cross-sectional shape in a longitudinal direction of the container.

8. The beverage container of claim 2 , wherein centers of the plurality of circular arcs form a polygon.

9. The beverage container of claim 2 , further comprising an outlet for the product.
