Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a container as a so-called shipping box used when transporting or conveying products.

[Prior Art] As shown in Japanese Utility Model Publication No. 54-20028, for example, a conventional container or transportation case has a box that is bent so as to have a handle hole in the center of both side plates, and a thickness of each side plate. It consists of a frame that hangs down with the same width and has a hook part between which the upper part of each side plate is inserted and which is hooked into the handle hole.When the frame is inserted into the upper part of the side plate of the box, the hook part It is hung in the handle hole while being elastically deformed.

In addition, as a container body installed in a container or a transportation case, for example,
As shown in Publication No. 177925, it has a large number of storage parts divided by a plurality of partition walls, and has a hanging piece that hangs down after extending horizontally at the upper end of the outer periphery. It is known that the device is attached by being hooked to the top of the three plates.

[Problems to be Solved by the Invention] However, in the case of the container or transport case described above, the frame is hooked to the box only through the hand holes in the pair of side plates facing each other.
Therefore, there is a problem in that the fixing strength between the box and the frame is weak.

Particularly, when carrying the frame attached to the upper part of the other side plate, which is not provided with a handle hole, there is a risk that the frame portion of the frame may come off the side plate and fall apart.

In addition, such containers and transportation cases are stacked in multiple tiers, but because the bottom surface of the container or transportation case located above is placed on the top surface of the frame, stacking is not possible. It is stable and has the risk of falling over with a small external force.

Furthermore, in the case of the container body attached to the container or transport case described above, the extension width of the latching pieces in the horizontal direction differs between adjacent side plates. For this reason, when forming the latching piece, high processing accuracy is required, resulting in high cost.

This invention was devised to solve the above-mentioned conventional drawbacks, and its purpose is to firmly fix the frame and the box body to have high strength and a stable state. To provide a container which can be stacked in multiple stages, and which can also be stably accommodated by simply fixing a container body for accommodating a product.

[Means for Solving the Problem] Therefore, the present invention has a rectangular frame shape, which hangs down on the inner side of the lower surface of the support stepped portion 11 formed planarly on the inner peripheral surface, and is spaced at appropriate intervals in the longitudinal direction.

Large diameter portion 7b and large diameter portion 7 that can be elastically deformed and gradually become larger in diameter
A product storage body 9 is integrally formed with a fixing pin 7 having a small diameter portion 7d on the opposite side to the insertion direction of b, and latching pieces 29a that are received in a number of storage portions 11 partitioned into a partition wall 29b. It is characterized by consisting of.

[Operation of the invention] Since the invention is configured as described above, the upper side plate of the box body bent into a box shape is inserted between the hanging wall and the support wall of the frame. At this time, the through hole of the support wall, the through hole of the side plate, and the hanging recess of the hanging wall are aligned. When the fixing pin is press-fitted into the through-hole of the support wall and the through-hole of the side plate in this state, the tip of the fixing pin is latched into the latching recess and elastically deformed, moving around the periphery of the through-hole of the support wall. The large diameter portion that has overcome this elastically returns and engages with the inner surface of the support wall, thereby preventing it from coming off.
