A liquid container is provided, which comprises a bag-forming flexible container body, a pouring outlet provided to communicate with an inside of the container body, and a support member provided in the container body for inhibiting deformation of the container body occurring near the pouring outlet when the contained liquid is sucked, in which the support members is a member reinforcing the container body with a form like a funnel narrowed at the pouring outlet. If the funnel-like reinforcing portion occupies almost one half of the surface area of the container proper, it can be prevented that the pouring outlet is closed even if the non-reinforced portion of the container body is housed in the support member when the contained liquid is discharged. Therefore, a contained liquid can be smoothly taken out, and the container is especially suitable for containing a liquid having a relatively high viscosity or a liquid sensitive to the contact with air and the like.
A liquid container which comprises a bag forming a flexible container body, wherein said container body is adapted to form an almost quadrangular prism which has an end face and bag side faces;
A liquid container which comprises a bag forming a flexible container body, a pouring outlet provided to communicate with an inside of the container body, and a support member contained in the container body for inhibiting deformation of the container body from occurring near the pouring outlet when a contained liquid is sucked through said pouring outlet, in which said support member reinforces the container body with a form like a funnel narrowed at the pouring outlet, wherein said container body forms a bag in an almost quadrangular prism shape, said bag having an end face;
A liquid container which comprises a bag forming a flexible container body that defines an interior volume, a pouring outlet provided to communicate with said interior volume of the container body, and a support member contained in the interior volume for inhibiting deformation of the container body from occurring near the pouring outlet when a liquid within said container body is removed through said pouring outlet, in which said support member reinforces at least part of the container body in an approximate funnel shape that is narrowed at the pouring outlet and is adapted to receive the non-reinforced portion of said container body as when the liquid contained within said container is removed through said pouring outlet.
