And

In the case body 2, a pair of side walls 4 are connected to each other by a band-shaped connecting wall 5 to form a granular material storage portion A, and a band-shaped window hole 6 is formed in the connecting wall 5 at the top. And
Further, an outlet 7 is formed in the upper part of the side wall 4. In the present embodiment, the side wall 4 has a vertically long rectangular shape, a radius is formed at two lower corners, a radius having a large radius of curvature is formed at one upper corner, and the other upper corner is an inclined side. And
The case body 2 is connected by the connection wall 5 having a relatively small width to form a thin, hollow rectangular parallelepiped case body 2 as a whole. The window hole 6 is formed in a band shape in the portion of the connecting wall 5 from the lower end of the inclined side to the lower end of the radius having a large radius of curvature through the upper side. Further, the outlet 7 is formed in a circular shape at a front position above the side wall 4 of the case body 2. Note that the shape of the outlet 7 is not limited to a circle, and various shapes can be adopted.

The lid 3 has a side plate 9 extending from at least one side edge of a top plate 8 whose rear side is rotatably connected to the connection wall 5 at the rear edge of the window hole 6 so that the side wall 4 of the window hole 6 is formed. The window hole 6 is fitted so as to be fitted between the upper end edges, and both sides of the finger hook 10 extending from the front end are projected and locked on the side walls 4 on both sides of the front end of the window hole 6 so that the window hole 6 can be opened and closed. In this embodiment, the case body 2 and the lid 3 are integrally formed of synthetic resin with the lid opened by about 180 ° (not shown), and the connecting wall 5 at the rear edge of the window hole 6 is formed. One side of the traversing side is rotatably connected to the other side via a thin hinge 11, and a finger hook portion 10 is extended at a free end of the end into a horizontal triangular prism shape. The finger hook 10 is configured such that the lower surface on both sides abuts against each inclined side of the side wall 4, and in this state, the window hole 6 is closed by the lid 3. The bottom plate 12 extends from the lower edge of the side plate 9 and the other side plate is not formed because it is integrally formed.

Further, an engagement projection 13 protruding from the side plate 9 to be detachably fitted to the outlet 7 is provided. The engaging projection 13 in the present embodiment is a dome-shaped projection having substantially the same size as the outlet 7, and is fitted to the outlet 7 to keep the closed state when the lid is open. When the lid 10 is pushed up to open, it is relatively easily detached from the outlet 7, and when the lid is opened, its edge engages with the upper surface of the case body side wall 4 to attach it in the closing direction by an elastic plate described later. The opening 7 is configured to be kept open against the force. The shape of the engagement protrusion 13 can be variously adopted depending on the shape of the outlet 7 as long as the shape can be disengaged from the fitted state of the outlet 7. However, the peripheral portion is tapered like the dome-shaped protrusion. The one formed is preferable in that the fitting with the outlet 7 can be released relatively easily.

In the present invention, the elastic plate 14 suspended from the lid 3 is provided.
The sliding protrusion 15 protruding from the lower part of the side surface of the case body side wall 4
The guide groove 16 is formed so as to be slidable up.
The elastic plate 14 can be elastically deformable in the front-rear direction. In the present embodiment, the elastic plate 14 has a flat plate shape that is vertically suspended from the front lower surface of the lid 3. Further, as shown in FIG. 2, the elastic plate 14 of the present embodiment also serves as a shielding plate for covering the front part of the window hole 6 which is opened when the lid is opened.

The guide groove 16 is formed such that the elastic plate 14 is not deformed when the lid is closed, and a biasing force is generated in the lid closing direction by the deformation of the elastic plate 14 when the lid is opened. As a specific example, the lower end of the guide groove 16 is provided at a position corresponding to the hanging position of the sliding protrusion 15 in the closed state, and the elastic plate is
The structure is such that a load is not applied to and a stable state without deformation occurs. At this time, the closed state can be maintained by fitting the engaging projection 13 to the outlet 7 and frictional force between the side surface of the lid and the case body.

Further, the upper end of the guide groove 16 is provided at a position deviated from the virtual rotation locus of the sliding protrusion, and when the sliding protrusion 15 is at its highest position, a load is applied to the elastic plate 14 to be in a deformed state. The lid 3 is configured to be urged in the direction of closing the lid.
The virtual rotation trajectory referred to here means that the lid 3 is moved at a predetermined angle from the hanging position of the sliding projection 15 in the closed state around the rotation connection portion (thin hinge 11) between the lid 3 and the case body 2. The rotation locus of the sliding protrusion 15 when rotated is referred to as shown in FIG.
It exists on a curve centered on the circle a. Further, in the open state, the edge of the engaging projection 13 is engaged with the upper surface of the case main body 2 against the above-mentioned biasing force, and the opening state of the outlet 7 is maintained.

The specific shape of the guide groove 16 can be variously selected as long as the above conditions are satisfied. In this embodiment, a linear guide groove is provided, and the sliding protrusion 15 in the open state is hung down. Guide groove extending linearly above the lower end corresponding to the position
16 are provided. In this embodiment, the guide groove 16 is formed as a cut groove penetrating the case body side wall 4, but is not limited to this, and may be formed as a concave groove provided on the inner surface of the side wall. However, in the case of a concave groove shape, it is difficult to integrally mold the case body and the lid. Further, in the case of the present embodiment in which the kerf-shaped guide groove is provided, the guide groove is exposed to the outside, but can be covered, for example, by attaching a label 17 as shown by a two-dot chain line in FIG.

When the lid 3 is opened by pushing up the finger hook 10 from the state shown in FIG. 1, for example, the engaging projection 13 comes off from the outlet 7, and the sliding projection 15 Is guided by the guide groove 16 to ascend to the upper end thereof, and the outlet 7 is opened. At this time, a force acts in a direction to close the lid 3 in order to return the elastically deformed elastic plate 14 to its original state,
On the other hand, the engagement projection 13 moves at least above the upper surface of the case body 2 and engages the edge thereof with the upper surface of the case body 2, and the opening of the outlet 7 is opposed to the urging force of the elastic plate 14 in the closing direction. Maintain state. Then, the stored particulate matter can be taken out from the outlet 7. After use, if the lid 3 is forcibly closed, the engagement projection 13 is disengaged and the lid 3 is closed, and the engagement projection 13 is fitted into the outlet 7 and the sliding projection 15 is The guide shifts to the lower end of the guide groove 16 in a state where no load is applied to the guide groove 16 to maintain a stable closed state.

FIGS. 5 to 9 show another embodiment of the present invention. In this embodiment, the linear guide groove 16 in the embodiment shown in FIG. A guide groove 16 is provided above the lower end portion corresponding to the hanging position of the sliding projection in FIG.
