Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container having a plurality of foldable legs on a bottom surface. 2. Description of the Related Art Conventionally, a liquid container used outdoors or the like has an inner container having a wide upper end, an outer case surrounding the inner container, a shoulder member connected to an upper end of the outer case, and an outer case. A bottom member coupled to the lower end of the case, a lid body detachably attached to the upper end of the shoulder member to open and close the wide opening of the inner container, a discharge mechanism for discharging the liquid in the inner container from the lower front surface, and a bottom member. Radially provided on the bottom surface at a predetermined interval, three U-shaped leg storage portions including left and right walls and a back wall, and foldable legs stored in each leg storage portion are provided. [0003] Then, drinking water such as cold water or warm tea is stored in the inner container, and the liquid container is carried to a place of use such as outdoors. Then, each leg in the leg storage portion is outwardly expanded, and the liquid container is opened. Was used in a standing state. [0004] However, in this type of liquid container, when the legs are opened, the lower end of the back wall of the leg storage portion comes into line contact with the back surface of the legs opened diagonally downward, so that the liquid container Weight (so-called full load) was supported by each leg. In addition, since the lower end of the back wall of the leg storage part under heavy load makes line contact with the diagonally downward leg, it is very unstable, and the leg is further greatly expanded outward, so that the predetermined liquid container If the height of the back wall cannot be maintained, or the back wall of the leg storage section is weak against the legs and curves outward, and if the back wall is not thick, There was a problem that damage was easily caused. Accordingly, the present invention has been made to solve the problem of the conventional liquid container, and has a very simple structure in which the lower end of the back wall of the leg storage portion and the obliquely downward leg are faced. An object of the present invention is to provide a liquid container having excellent stability without restricting outward expansion of the legs by making contact with the legs, or without increasing the thickness of the back wall of the leg storage portion. In order to achieve the above object, the liquid container of the present invention has an inner container 2 having a wide-open upper end, an outer case 3 surrounding the inner container 2, and an outer case 3 A shoulder member 4 connected to an upper end of the outer case 3, a bottom member 5 connected to a lower end of the outer case 3, and a detachably mounted upper end of the shoulder member 4;
