FIG. FIG. 6 is a sectional view taken along line VI-VI of FIG.
[0011]
The transport container frame 1 has a box shape with a bottom and is detachably mounted on the upper surface of a synthetic resin container body 3 having a flange 2 on the outer periphery of the upper surface opening. A rectangular frame 11 made of synthetic resin corresponding to the outer periphery, a flange 12 provided on the inner periphery of the frame 11, and horns provided on two opposite sides of the frame 11. The frame body 11 includes a projection 13, a projection 14 with a hypotenuse, and a lid 16 that can be opened and closed via a hinge 15 provided on one side of the frame body 11. And a mounting portion 18 of a locking device provided on the lid 16 as necessary.
[0012]
The lower surface of the flange body 12 contacts the upper surface of the flange 2 of the container body 3 when the transport container frame 1 is mounted on the container body 3 to support the transport container frame 1. The distance between the lower surface of the body 12 and the upper surfaces of the angular projection 13 and the oblique projection 14 is set to be substantially equal to the thickness of the flange 2. When an elastic body such as a packing or a foam is provided on the lower surface of the collar body 12 in order to prevent rattling of the transport container frame 1, the distance between the two is taken into consideration in consideration of the thickness and the amount of deformation of the elastic body. Set.
[0013]
The horn-shaped protrusions 13 are provided one by one in the vicinity of both corners of one side of the frame main body 11, and the upper surface contacting the lower surface of the flange 2 is formed in a planar shape. As shown in FIGS. 5 and 6, a longitudinal groove 13 a for mounting a spacer 19 is provided on both side surfaces of the angular projection 13, and the flange body 12 is provided above the angular projection 13. A notch 12a for mounting the spacer 19 is provided.
[0014]
On the other hand, the oblique-side projection 14 is provided so as to substantially oppose the angular projection 13, and an inclined surface 14 a of which downward is directed toward the frame main body 11 is formed on a protruding end surface thereof. The size of the projection 14 with the hypotenuse is formed slightly smaller than that of the angular projection 13, but the distance between the upper surface thereof and the flange 12 is formed in the same manner as the angular projection 13.
[0015]
When mounting the transport container frame 1 configured as described above to the container main body 3, first, one side of the side on which the angular projection 13 is provided is brought into contact with the flange 2 of the container main body 3, and the flange 2 is attached. After being sandwiched between the angular projection 13 and the flange body, the side on which the hypotenuse projection 14 is provided is pressed against the container body 3 side. Thereby, the inclined surface 14a of the projection 14 with the hypotenuse moves so as to slide down the edge of the flange 2, and the projection 14 with the hypotenuse rides over the flange 2 and is locked on the lower surface of the flange 2, and is transported with the container body 3. The container frame 1 is integrated.
[0016]
When removing the transport container frame 1 from the container body 3, the frame body 11 on the side provided with the projection 14 with the oblique side may be lifted so as to spread outward. Thus, the locked state between the projection 14 with the oblique side and the flange 2 can be released, and the transport container frame 1 can be removed.
[0017]
In the mounting and dismounting of the transport container frame 1 described above, it can be more easily attached and detached as compared with the case where square projections are provided on both sides of the frame main body 11, and the mounting strength is improved as compared with the case where the inclined projections are provided on both sides. Can be.
[0018]
It should be noted that the closer the installation position of the beveled projection 14 is to the corner of the frame main body 11, the smaller the amount of deformation of the frame main body 11, so that the locking force between the beveled projection 14 and the flange 2 can be increased and ensured. . However, in this case, a large force is also required for attaching and detaching the transport container frame 1, so that the hypotenuse projection having the optimal size is located at an optimal position according to the size and strength of the container body 3 and the frame body 11. Preferably, 14 is provided.
[0019]
The spacer 19 is formed in a substantially L-shape when viewed from the side, and has a T-shaped notch having a protruding side 19 a having a projection 19 a that engages with the vertical groove 13 a of the square projection 13 on the base side. The groove 19b is provided, and the thickness (vertical dimension) of the angular projection 19c at the tip is set to be substantially the same as that of the angular projection 13.
[0020]
The spacer 19 is used when the transport container frame 1 is mounted on the container body 3 having an upper opening smaller than the transport container frame 1, and includes the horn-shaped projection 13 provided on the frame body 11 and the hypotenuse. It is used when the flange 2 cannot be locked with the attached projection 14.
[0021]
That is, when the spacer 19 is mounted on the angular projection 13 from above, the angular projection 19c at the tip of the spacer 19 projects toward the inner peripheral side of the frame main body 11, and the distance between the opposing oblique-side projection 14 is reduced. Therefore, the transport container frame 1 can be attached to the container body 3 having the upper opening one or two times smaller than the transport container frame 1 in the same manner as described above. Therefore, by preparing a plurality of spacers 19 in which the protrusions of the angular projections 19c at the tip end are different, one transport container frame 1 can be mounted on a container body having various opening dimensions.
[0022]
In addition, by providing the lid 16 made of synthetic resin, cloth, or the like on the transport container frame 1, the container body 3 having an open top can be used as a container with a lid, and dust and water can be prevented from entering. . Further, a locking device may be provided for security measures or the like. In this case, by forming the outer peripheral frame of the lid 16 firmly, it is possible to prevent the frame main body 11 from spreading outward when the lid 16 is closed, and the transport container frame 1 is moved from the container main body 3. It can be prevented from being removed.
[0023]
By forming the upper edge of the frame main body 11 in the same shape as the flange 2 of the container main body 3, the transport container frame 1 can be further mounted on the transport container frame 1.
[0024]
