The side opening type container of the present invention will be described with reference to FIG. 3 which is a perspective view of the nesting state.
[0009]
In the open side container C according to the present invention, a side wall 2 in which no opening recess is formed is erected from one opposite side portion of the bottom portion 1 having a flat bottom surface. From one opposite side, a side wall 3 having an appropriate height, for example, approximately one third of the height of the side wall 2 where no opening recess is formed (hereinafter, this side wall is referred to as the conventional side wall). As in the case of the open side container, the “open side wall” is simply set up. 4 is a fitting piece extending upward from both ends of the upper end portion 3a of the opposite open side wall 3 and having a substantially square front shape when viewed from the open side wall 3. The fitting piece 4 has an opening recess. It is preferable that the height of the side wall 2 that is not formed is less than one third of the height. Reference numeral 5 denotes a fitting groove formed in the vicinity of both ends of the outer wall of the opposite open side wall 3 and extending substantially vertically. The lower end 5a of the fitting groove 5 is open, and the fitting groove A top wall 5 b is formed at the upper end of 5.
[0010]
As shown in FIG. 2, the side-open container C includes a side-open container C <b> 1 located above and a side-open container C <b> 2 located below are side walls on which no opening recesses are formed. 2 are arranged so as to be orthogonal to each other, and then the bottom 1 of the upper side open container C1 is placed on the upper end 3a of the open side wall 3 of the lower side open container C2.
