Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a foldable container suitable for storing and transporting a bulky and relatively lightweight packaged cargo, particularly an egg packaged in a commercial plastic container.

[0002]

[Prior Art]

 For example, the transportation and storage of eggs packed for business use is carried out by loading them on a fixed rack. However, since the size of the rack does not conform to the size of the pack, it may cause damage to the pack or rupture of the egg due to misalignment during transportation, causing instability in transportation. In addition, the height of the rack is low, the height of the transportation vehicle cannot be used effectively, the transportation efficiency is low, and the empty rack cannot be folded when it is collected, so it requires the same volume as the net transportation, increasing the transportation cost. ing.

[0003]

[Problems to be solved by the device]

 In consideration of the above situation, the inventor has a tall container that is efficient during transportation and storage in order to eliminate instability during transportation and improve transportation efficiency, and can be folded when not in use. The present invention was completed based on the idea of making the frame on the wife side of the container foldable and allowing it to be pulled out in two stages.

[0004]

[Means for Solving the Problems]

 According to the present invention, (A) a collapsible girder frame which is provided with side pillars, intermediate pillars, upper girders and lower girders at the opposite side edges of the pallet having a bottom plate, and which is provided so as to be foldable and erectably fixed ( B) A pull-out gable frame which is composed of a loose-fitting side column, a loose-fitting intermediate column and an upper cross girder which are respectively loosely fitted in the side column and the intermediate column of the gable frame, and which can be pulled out and fixed from the folding gable frame; (C) A lower frame in which side ends are detachably mounted between the opposing end frames in the standing state; (D) Between the pull-out end frames placed and held on the lower frame. A foldable container is provided, which comprises an upper frame to which side ends are detachably mounted. That is, a foldable gable frame is provided on the side edge of the container, the drawer gable frame is stored in the gable frame, the folding gable frame is erected, and then the drawer gable frame is pulled out from the folding gable frame and fixed. The upper and lower side frames are attached between the left and right upper and lower gable frames to form a container.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view after assembly. Folding gable frames 3 and 3 are erected on opposite gutter side edges of a pallet 1 provided with a bottom plate 2, and withdraw gable frames 4 and 4 are pulled out from the grate frames. , It is fixedly installed on the side pillar of the folding gable frame. Between the folding gable frames 3 and 3, the lower frames 5 and 5 are fixedly erected with both end portions fitted respectively, and the upper frame 6 is placed and held on the lower frame between the upper drawer gable frames. , 6 are fitted and fixed to form a container.

The method of erection of the folding gable frame may be a publicly known appropriate method, but in this embodiment, as shown in FIG. 2, a gable frame base material 8 having a mountain cross section surrounding the side pillar 7 of the folding gable frame is vertically An elongated guide hole 9 is provided, and a guide pin 10 projecting from the side pillar 7 is loosely fitted in the guide hole 9, so that the folding gable frame can be rotated inward to be folded. Further, a fixing pin 11 is provided on the side pillar 7, and the supporting pin is erected to pull up the guide pin along the guide hole to fit the fixing pin in the fitting groove 12 of the base material and to stand vertically. The side pillars 7 of the folding gable frame are made of square pipes, the drawer side pillars 13 are loosely fitted in the pillars, and the middle pillars 14 are made of square pipes or channel members, and the drawer middle pillars 15 are loosely fitted, The drawer gable frame 4 can be pulled out or pushed in from the folding gable frame. As shown in FIG. 1, the pull-out gable frame 4 is pulled up to the upper end, and is removably fixed to the side column of the folding gable frame with a stopper 16. Next, as shown in FIG. 3, the side pillar portion of the lower frame 5 and the folding pillar frame side pillar portion are joined together by inserting the lower frame into the groove surface of the side pillar 17 and inserting it from above along the side pillar of the wife frame. Then, the L-shaped member 19 provided between the inner surface of the side pillar 17 of the lower frame and the lower edge member 18 is brought into contact with the inner surface of the gable frame base material 8 and the latch metal fitting provided at the corner of the side pillar 17. Insert 20 into the side pillar 7 of the gable frame and fix. In the upper frame 6, the pins provided on the lower surface of the lower edge member of this frame are inserted and held in the pin insertion holes punched corresponding to the upper surface of the upper edge member of the upper frame 6, and the upper frame 6 shown in FIG. The latch metal fittings 21 provided at the corners of the upper edge material are inserted and fixed in the drawer side columns 13 of the drawer grate frame, and the assembly of the container is completed.

[0007]

[Action]

 Next, a case of using it for a commercial packed egg will be described. The container is erected on the left and right girder frames as above, and egg packs are loaded on the bottom plate. For example, 6 eggs are arranged in a row, 6 rows of these eggs are staggered between the upper and lower packs of a plastic egg receiver, and the upper egg pack is inserted into the space formed between the lower egg receivers. For example, stack 6 levels. A vertical partition plate is placed between the stacked packs on the left and right to prevent the packs from swinging. Next, an empty pack is placed with the edge plane facing up to form a horizontal plane with the pack edge planes laid side by side, and the horizontal plate of the inner size of the container is placed on this. The egg pack is packed up on this side plate as described above. The pack load from above is received by the horizontal plate supported by the vertical partition plate to support the load and prevent the load from being locally concentrated. After loading, attach the front and back upper and lower frames for transportation and storage. After loading and unloading the container, release the latch fittings, remove the upper and lower frames on the front and rear, retract the drawer gable frame, remove the fixing pin of the folding gable frame from the fitting groove of the base material, and remove the guide pin. It can be folded inward using the fulcrum, and the upper and lower frames, vertical partition plates, and horizontal plates can be stacked to easily combine them into a small volume. Although the case of the egg pack has been described above, it can be similarly used for transportation and storage of a relatively lightweight and bulky item that is easily damaged.

[0008]

[Effect of the device]

 According to the present invention, unlike the conventional rack, the height of the container can be increased and the container can be folded, so that it can be folded into a small volume when not in use, which makes it easy to handle and greatly reduces logistics costs. In particular, egg packs are useful because they can carry a large amount of load and prevent rupture of eggs.
