Claims
- 1. A container comprising:
a self-standing container body including a wall formed of a soft sheet and a bottom, wherein said bottom is expandable when content is contained within said self-standing container body such that said container stands unaided; a pouring port disposed at an end portion of said self-standing container; and a check valve mounted in said pouring port, said check valve being operable to open when a pressure within said self-standing container in greater than a pressure outside of said self-standing container and close when the pressure outside of said self-standing container is greater than the pressure within the self-standing container, wherein
an inside of said container is evacuated by a vacuum that is established by a weight of the content contained within said self-standing container body, and said wall contains a first pair of outward folds and a second pair of outward folds extending from said pouring port towards said bottom, said first and second pairs of outward folds being positioned such that said self-standing container body does not fold over when said container stands upright.
- 2. A container comprising:
a container body including a wall formed of a soft sheet, and a bottom attached to a first end of said wall, said bottom being expandable when content is contained within said container body such that said container stands unaided; a pouring port comprising a cylindrical member attached to a second end of said wall; and a check valve disposed in said pouring port, said check valve being operable to prevent the backflow of air into said container when the content is discharge from said container, wherein
an upper portion of said container is evacuated when said container is stood upright after a portion of the content is discharged by downward migration of a remaining portion of the content due to gravity, and said wall contains a first pair of outward folds and a second pair of outward folds extending from said pouring port towards said bottom, said first and second pairs of outward folds being positioned such that said container body does not fold over when said container stands upright.
- 3. A container as set forth in claim 1, wherein said check valve has a domed head containing a cut, wherein said cut is opened when the pressure from within said self-standing container is greater than the pressure outside of said self-standing container and closed when the pressure outside of said self-standing container is greater than the pressure within said self-standing container.
- 4. A container comprising:
a self-standing container body including a wall formed of a soft sheet and a bottom, wherein said bottom is expandable when content is contained within said self-standing container body such that said container stands unaided; a pouring port disposed at an end portion of said self-standing container; a check valve mounted in said pouring port, said check valve being operable to open when a pressure within said self-standing container in greater than a pressure outside of said self-standing container and close when the pressure outside of said self-standing container is greater than the pressure within the self-standing container, wherein an inside of said container is evacuated by a vacuum that is established by a weight of the content contained within said self-standing container body; and a flow velocity control mechanism located between said self-standing container body and said pouring port, said flow velocity control mechanism including a flow velocity control unit having a passage communicating between said self-standing container body and said flow velocity control mechanism, said passage eliminating a flow velocity of the content when the content flows into said flow velocity control unit from said self-standing container body.
- 5. A container as set forth in claim 2, wherein said check valve has a domed head containing a cut, wherein said cut is opened when the pressure from within said container is greater than the pressure outside of said container and closed when the pressure outside of said container is greater than the pressure within said container.
- 6. A container comprising:
a container body including a wall formed of a soft sheet, and a bottom attached to a first end of said wall, said bottom being expandable when content is contained within said container body such that said container stands unaided; a pouring port comprising a cylindrical member attached to a second end of said wall; a check valve disposed in said pouring port, said check valve being operable to prevent the backflow of air into said container when the content is discharge from said container, wherein an upper portion of said container is evacuated when said container is stood upright after a portion of the content is discharged by downward migration of a remaining portion of the content due to gravity; and a flow velocity control mechanism located between said container body and said pouring port, said flow velocity control mechanism including a flow velocity control unit having a passage communicating between said container body and said flow velocity control mechanism, said passage eliminating a flow velocity of the content when the content flows into said flow velocity control unit from said container body.
- 7. A container comprising:
a self-standing container body including a wall formed of a soft sheet and a bottom, wherein said bottom is expandable when content is contained within said self-standing container body such that said container stands unaided; a pouring port disposed at an end portion of said self-standing container; and a flow velocity control mechanism located between said self-standing container body and said pouring port, said flow velocity control mechanism including a flow velocity control unit having a passage communicating between said self-standing container body and said flow velocity control mechanism, said passage eliminating a flow velocity of the content when the content flows into said flow velocity control unit from said self-standing container body.
