The pad of the fingertip is applied to the lower end surface (lower edge) of the fitting portion 40 for the inner plate 16, and the tongue piece 44 is used as a gripping point (contact point) on the inner plate 14 side with the thumb and forefinger of the left hand. Grab it as if pinching from. In this state, by applying a force in the direction of lifting the upper lid 16 with a fingertip touching the lower edge of the middle plate fitting portion 40, the engagement between the middle plate 14 and the upper lid 16 is achieved by the engagement of the concave groove 36 and the ridge 42. Even if the stopper is strong, the upper lid 16 can be removed from the inner plate 14 with good workability.

That is, due to the presence of the recessed portion 50, the fingertips can be easily and reliably brought into contact with the lower edge of the intermediate plate fitting portion 40 that extends across the recessed portion 50. Even if the upper lid 16 is difficult to come off from the tray 14 carelessly, the operation of removing the upper lid 16 from the inner plate 14 can be performed with good workability. Since the recessed portion 50 is provided at the corner portion 28A, it is easier to insert the fingertip into the recessed portion 50 than if it is provided in the middle of the side portion.

The shelf portion 38 can be a portion (contact portion) that is pinched or pressed downward by a fingertip different from the fingertip inserted into the recessed portion 50 when the upper lid 16 is removed from the inner tray 14 . As a result, instead of gripping the tongue piece 44, the thumb of the left hand or the like is applied to the shelf 38, the thumb of the right hand or the tip of the forefinger is inserted into the recess 50, and the fingertip is inserted into the lower end surface 40A of the fitting portion 40 for the inner tray. You may make it hit to.

It can be changed appropriately as long as it does not occur.

For example, the recessed portion 50 does not necessarily have to be open to the middle plate flange portion 26, and a fingertip is placed from the outside on the lower edge of the middle plate fitting portion 40 of the upper lid 16 in a state where the middle plate 14 is mounted. If it is opened toward the lower edge of the middle plate fitting portion 40 of the top lid 16 attached to the middle plate 14 so that it can be easily applied, the upper lid fitting cylindrical portion 28 is opened. It is sufficient if it extends halfway to the edge. The depression 50 does not necessarily need to be provided at the corner 28A of the upper lid fitting tubular portion 28, nor does it need to be provided at each corner 28A. good.

The recessed portion 50 can also be applied to the case where the top lid fitting tubular portion 28 has a cylindrical shape or the like. That is, the shape of the upper lid fitting cylindrical portion 28 of the middle plate 14 and the middle plate fitting cylindrical portion of the upper lid 16 that are fitted to each other may be a cylindrical shape, an elliptical shape, a rectangular shape, a polygonal shape, or the like. may be The concave-convex engagement between the middle plate 14 and the upper lid 16 is achieved by forming a ridge in the upper lid fitting portion 28 and forming a groove in the middle plate fitting portion 40. It may be done by engagement. Further, the concave-convex engagement between the middle plate 14 and the upper lid 16 may be performed by engagement between a point-like convex portion and a concave portion, instead of using the protrusion 42 and the concave groove 36 .
