2. Description of the Related Art Conventionally, a box-shaped container having a rectangular parallelepiped box body with an openable lid is widely used as a container for storing powdered substances such as powder detergents and powder bleaching agents. Has been. However, in general, such a box-shaped container for powdery or granular material is entirely made of paperboard, so that it cannot be said that the peripheral wall surface of the box body or the ceiling surface of the lid portion is sufficiently strong. Furthermore, in a box-shaped container in which a reinforcing plate is attached and adhered to the inner wall surface of the box body, in the product transportation process from the production to the reach of the consumer or the consumer's use stage,
The particles in the box sometimes entered the gap between the box body and the reinforcing plate and stayed there, absorbing moisture and solidifying.

As a method for preventing the infiltration of powder particles into the gap, for example, it is considered that an adhesive is applied to the entire surface of the reinforcing plate and the reinforcing plate is attached to the entire inner wall surface of the box body without any space. Considering the productivity of the box making work, it is not a good idea to bond the entire surface of the box body and the reinforcing plate without any gap,
It is necessary to form a gap of about 0.3 to 3.0 mm between the box body and the reinforcing plate. For this reason, it is general that the box body and the reinforcing plate are dot-attached at a plurality of places so that a gap of about 0.3 to 3.0 mm is formed.

In order to achieve the above object, the present invention provides a powder grain having a box-shaped box body and a lid portion which is openably and closably capped on an upper opening surface of the box body. In a box-type container for storing objects, a reinforcing plate is attached by sticking at least along the inner wall surfaces of the front plate and the left and right side plates of the box body, and the lower side of the reinforcing plate is cut upward. The concave portion having a desired shape is formed.

With the above structure, even if the powder / granular material in the box enters the gap between the box body and the reinforcing plate, the powder / granular material that has entered is again removed from the notch formed in the lower side of the reinforcing plate. It is returned to the box body. Therefore, during the product transportation process from the production to the consumer's reach or the consumer's use stage, the powder and granules in the box do not enter the gap between the box body and the reinforcing plate and stay there. There is no need to absorb moisture in the gap and solidify. Also,
The reinforcing plate provides sufficient strength to the peripheral wall surface of the box body and the ceiling surface of the lid, and does not easily deform.

As the powdery or granular material to be stored in the box-shaped container of the present invention, the bulk density is 0.7 to 0.95 g / ml, 1000
The residue when sieving with a μm sieve is 16
% Or less, and a powder or granule having a passing content of 14% or less when sieved with a 150 μm sieve is suitable. When the powder or granules in such a range are stored, the above-mentioned operational effects are further exhibited.
