ABSTRACT:
A liquid container having a stable shape that is easy to fill and that enables the user to pour out liquid to the last drop into an intended target using one hand only and without spilling the liquid. An internal space of a container is defined by a front surface portion, a rear surface portion having the shape identical with the front surface portion, and a pair of gussets each connecting together each confronting edges of the front and rear surface portions. The gusset has a folded arrangement. If liquid is filled in the container, V-shape of the gusset expands to provide a three dimensional container. The gussets extend to a neck portion. By the expansion of the gussets, a spout has a sufficient open area capable of controlled pouring of the liquid therethrough. If the liquid amount in the container is reduced, the spout is automatically closed when the container is self-standing on a table.
