  The front wall 16a, the flange 17a, the side walls 19a, 19b, the upper wall 20, and the front end wall 18 form an upper opening B2 on the upper case A2 side of the outlet B, and the upper side of the outlet B by the cam plates 22a, 22b. The opening / closing mechanism is formed.

Next, the effect of this storage container is demonstrated.
The lower case A1 and the upper case A2 of the storage container A are each molded by injection molding, thermoforming or the like using PE or other flexible synthetic resin.
In the molded lower case A1 and upper case A2, the storage container A is obtained by overlapping the flange 3 and the flange 17 and welding the flanges 3 and 17 in a predetermined range.

  The outlet B is formed by welding while leaving the overlapping portions of the flange 3a and the flange 17a and the arc portions 25a and 25b for forming openings.

At that time, the upper surfaces of the upper and lower cam plates 8a, 8b of the lower case A1 are in contact with the upper wall 20 of the upper case A2, and the lower surfaces of the cam plates 22a, 22b are in contact with the lower wall 6 of the lower case A1. ing.
Further, the convex strips 10a, 10b and the convex strips 23a, 23b of the cam plates 8a, 8b and the cam plates 22a, 22b are concave grooves provided in the front end wall 4, the front wall 2a, the front end wall 18, and the front wall 16a. 11a and 11b and the grooves 24a and 24b are engaged, and the upper and lower flanges 3a and the flanges 17a maintain a tight contact state.

Next, the opening and closing of the outlet B and the operation and effect at that time will be described.
As shown in FIG. 5, when the flanges 3a and 17a are pressed from both sides, the inclined cam surfaces 7 of the cam plates 8a and 8b and the inclined cam surfaces 21 of the cam plates 22a and 22b are pressed against each other and slid to each other. The protrusions 10a and 10b, the protrusions 23a and 23b and the grooves 11a and 11b and the grooves 24a and 24b are disengaged, and the cam plates 8a and 8b and the cam plates 22a and 22b move relative to each other. The wall 6 is moved downward and the upper wall 20 is moved upward, so that a gap is formed between the flange 3a and the flange 17a, and an opening 26 is formed.

  At that time, the thickness of the side walls 5a and 5b, the lower wall 6, the side walls 19a and 19b, and the upper wall 20 is larger than the thickness of the flange 3a and the flange 17a, so that the flange 3a and the flange 17a are first deformed to be inclined. Then, as shown in FIG. 5 (b), the lower wall 6 and the upper wall 20 are opened so as to widen the space vertically.

Next, the upper surfaces of the cam plates 8a and 8b and the lower surfaces of the cam plates 22a and 22b come to be joined, and as shown in FIG.
Further, when both ends are pressed, the cam plates 8a and 8b are greatly separated to form a substantially circular opening 26 as shown in FIG. 5 (d).

  The shape of the outlet B is determined by the size and shape of the granular material, and the extent of the opening 26 in each of the above states is determined by the user according to the size and shape of the contents. I can leave it to you.

  When closing the outlet B, if the pressing on both sides of the flange 3a and the flange 17a is stopped, the flange 3a and the flange 17a are made of a flexible synthetic resin. When the wall 6 is lightly pressed from above and below, the cam plates 8a and 8b and the cam plates 22a and 22b also return to the initial state, and the convex strips 10a and 10b and the convex strips 23a and 23b correspond to the concave grooves 24a and 24b and concave portions, respectively. The outlet B is closed by fitting into the grooves 11a and 11b.

  The opening of the outlet B can be easily advanced even if the pressing force is small because the cam plates facing each other move in the vertical direction by the inclined cam surface. It is reliably performed by a simple operation only by light pressing from above and below.

In the said embodiment, although shape | molded so that the shape of an upper case and a lower case might differ, an upper and lower case can also be made into the same shape.
In that case, since the storage container can be formed simply by stacking the cases molded with the same mold and welding the required portion of the flange, the production cost can be reduced.

Since the outlet of the storage container is opened by the inclined cam surface of the opposing cam plate, the opening can be easily made by pressing both sides of the outlet with a small pressing force.
As a result, the opening state can be selected according to the size and shape of the granular material, and the range of use of the granular material container can be expanded.
