Description

  The present invention relates to a foldable container container that can be stored flat by folding it flat when not in use and can store liquids, fluids, powders, etc. by installing an interior bag inside when in use. .

  Container containers with a rectangular outer shape are useful for transporting and storing goods because there is no dead space and good space efficiency when many containers are stacked and placed side by side during storage and transportation. .

  However, since conventional container containers are made of iron and are strong but heavy, and the container containers themselves take up the same space when not in use and are not used for storage or transportation, they are wide enough to store these container containers. It was necessary to secure a place.

  Therefore, recently, a folding container that can be assembled at the time of use by separating the six rectangular surfaces has been adopted, and when the container container is not used, it is folded to save space.

  In addition, the material of the plate-like body forming the six surfaces of the container container is not only a metal but also a light material such as a wooden or synthetic resin, and the container container itself can be reduced in weight. Has also been made convenient.

  Conventionally, when storing or transporting stored items such as liquids, fluids, granules, powders, etc., in order to prevent contamination of the inner wall of the container, the outer outer container is made of synthetic resin and sealed. Store the interior bag, store the liquid, fluid, granule, powder, etc. in the interior bag and store or transport it. After the storage or transport is finished, remove the stored item. The inner bag is taken out and discarded, so that it is not necessary to clean the inner wall of the outer container, and when it is used again, it is generally replaced with a new inner bag.

  Even in a foldable container container, it is possible to store and transport stored items such as liquids, fluids, granules, and powders by storing an interior bag therein (see, for example, Patent Document 1). ).

  As shown in the perspective view of FIG. 4, the tube port 7 a of the inner bag 7 when stored in the outer container 1 is held over a notch 3 a provided on the upper side of the pair of side plates 3 facing the outer container 1. It protrudes upward through the through-hole 5a of the plate 5.

  The actual mounting method of the interior bag 7 is as follows. First, the tube port 7a of the unused interior bag 7 in the folded state is passed through the through hole 5a of the holding plate 5, and in this state, the engaging groove 5b of the holding plate 5 is engaged. The engaging member 6 is inserted into the holding plate 5 to fix the inner bag 7.

  As shown in FIG. 5 (A), the fixing structure is such that the portion of the engagement recess 6a in the shape of the tip V groove of the engagement member 6 that advances in the engagement groove 5b is held as shown in FIG. 5 (B). It reaches the through hole 5a of the plate 5 and comes into contact with the body portion of the tube port 7a in the through hole 5a.

  Then, the bottom surface of the flange portion 7b of the tube opening 7a comes into contact with the engaging member 6, so that the tube port 7a is prevented from coming off.

  With the engaging member 6 engaged with the holding plate 5, the both-end locking portions 5 c of the holding plate 5 are hooked and fixed on the notches 3 a of the side plate 3 of the outer container 1, and then the air is internally supplied through the tube port 7 a. The interior bag 7 is inflated by appropriate means such as being introduced into the bag 7 to obtain the state shown in FIG.

  In the means for fixing the holding plate 5 (interior bag 7) to the outer container 1, the side plate 3 does not necessarily have to be provided with the notch 3a, and a mark or the like is added near the center of the upper side of the side plate 3, It is also possible to check the mark visually and hang the locking portion 5c of the holding plate 5.

  In the state shown in FIG. 4, storage items such as liquid, fluid, powder, and particles are stored in the interior bag 7 through the cylindrical port 7 a fixed near the center of the upper surface of the outer container 1.

  When the storage is completed, the tube port 7a is sealed by appropriate means such as binding the tube port 7a, and the engagement member 6 is pulled out from the engagement groove 5b of the holding plate 5, thereby releasing the tube port 7a from the holding plate 5 and dropping it downward.

  Thereafter, as shown in FIG. 6, the cover plate 4 is closed while the holding plate 5 is locked to the open upper surface of the outer container 1, and the belt 8 is further attached to the groove portion 2 a of the bottom plate 2 and the groove portion 4 a of the cover plate 4. The belts 8 are fastened with the belt 8 passing through the belt conducting portions 2b and 4b at the end portions of the respective groove portions 2a and 4a, and the belts 8 are connected to each other by a hook-and-loop fastener 8a provided at an appropriate place such as the end portion of the belt 8. Is fixed, the cover plate 4 of the outer container 1 is fixed, and the bottom plate 2, the side plate 3, and the cover plate 4 are firmly fixed to each other.

  The container containers having a rectangular shape in FIG. 6 are used by arranging a plurality of container containers as they are, storing them in a warehouse, transporting them in a vehicle or the like.

  After storage and transportation are completed, the hook-and-loop fastener 8a of the belt 8 is removed and the belt 8 on the cover plate 4 is removed, and then the cover plate 4 is removed and the tube port 7a that has been tied up from the interior bag 7 is released. The stored items are taken out by appropriate means.

  After the container container is used, the holding plate 5 is removed and the inner bag 7 is taken out. Further, the side plate 3 is removed from the bottom plate 2, and the side plate 3 is separated into pieces or the boundary between adjacent side plates 3 is folded into a flat plate shape. Then, it can be stored and transported after it is flattened by overlapping with the bottom plate 2 and the cover plate 4 so that the used outer container 1 does not take up space.

  FIG. 7 is a perspective view showing another example of the side plate 3 constituting the container container of the present invention. The side plate 3 of this embodiment is such that all the side plates 3 can be bent by hinges such as hinges at the side edges. Connected, it is a single square tube, and can be valley-folded along the vertical direction at the center of two opposing side plates 3 (side plates without cutouts 3a) when viewed from the outside with a hinge such as a hinge. A fold line 3b is provided.

  When the side plate 3 of this embodiment is stored as a container container before or after use, if the two side plates 3 are valley-folded along the fold line 3b as shown in FIG. 3 can be folded very easily into a flat plate having the same area.

  Thus, after making the four side plates 3 into one flat plate shape, the bottom plate 2 and the cover plate 4 are overlapped with the side plate 4 and the holding plate 5 sandwiched as shown in FIG. If the belt 8 is tied up to the grooves 2a and 4a of the bottom plate 2 and the cover plate 4 as described above, the exterior container can be stored compactly.

  FIG. 9 is a perspective view of a protective sheet 9 used in a container container according to still another embodiment of the present invention.

  The role of the protective sheet 9 is that if the interior bag 7 is damaged, the liquid, fluid, powder, etc., which is the stored item, has come out from the damaged portion of the interior bag 7 to the outside. Since the outer container 1 is likely to have a gap at the junction between the bottom plate 2 and the side plate 3 or the hinge portion between the adjacent side plates 3, the inner surface of the outer container 1 and the inner surface of the outer container 1 are prevented in order to prevent accidental leakage of stored items. It is interposed between the bags 7 and is made of a synthetic resin material having flexibility, flexibility, toughness and durability, such as made of vinyl chloride, and can be formed in a rectangular shape of the same type as the inner surface of the outer container 1. It has become.

  As a method for manufacturing the protective sheet 9, as an example, a synthetic resin formed in a cylindrical shape is bent inward at the opposite side of the side as shown in FIG. 9, and one end (the lower side in the figure) is X-shaped. The weld 9a is formed and sealed. At this time, the vertical dimension of the protective sheet 9 is set longer than the inner height of the outer container.

  Next, the part that is folded inward is widened, the other end (upper side in the figure) is formed into a square opening, the whole is made into a rectangular tube, and the lower end where the welded portion 9a is formed is also upper When the same bottom surface as the opening is formed, welding is performed at the four corners of the bottom surface as shown in a perspective view from above (FIG. 10A) and a perspective view from below (FIG. 10B). By spreading a surplus piece including the welded portion 9a generated for this purpose from the portion where the portion 9a is formed and by bending it at the bent portion 9b, the rectangular shape with the open top surface is obtained.

  At the time of manufacturing the protective sheet 9, when the rectangular shape shown in FIG. 10 is used, it is made to coincide with the dimensions of the inner surface of the outer container 1 to be used, and is stored in this shape on the inner surface of the outer container 1, The interior bag 7 is accommodated in the upper opening of the protective sheet 9.

  The protective sheet 9 shown in the drawing is merely an example, and can be manufactured by other known methods such as welding of five synthetic resin flat sheets to form a rectangular shape with an open top surface. In short, the obtained protective sheet does not affect the capacity of the interior bag, and has a toughness that can achieve the purpose of preventing the leakage of stored items when the interior bag is broken, Any material having durability may be used.

  FIG. 11 is a perspective view of the state in which this protective sheet 9 is combined with the side plate 3 shown in FIG. 7, and the bottom X shape and the folded shape of the four side plates 3 at the time of manufacturing the protective sheet 9 shown in FIG. In addition, the protective sheet 9 is stored in the folded side plate 3 in advance, and a plurality of places are detachably connected and fixed by appropriate means (such as a hook-and-loop fastener).

  At this time, as shown in the figure, the upper end sides of both are aligned, and the lower surface side where the welded portion 9a of the protective sheet 9 inevitably protrudes is folded back to the outside of the side plate 3 as shown in FIG. As shown, the outer container 1 can be compactly folded and stored while being integrated with the protective sheet 9.

  When the container container is used, the inner protective sheet 9 is also expanded into a rectangular shape at the same time by simply expanding the folding line 3b of the side plate 3 into a rectangular shape, and the outer container 1 can be easily assembled.

  As mentioned above, although embodiment of the folding container container of this invention was described, this invention is not limited to the content of the said embodiment, It can implement suitably changing within the range of the objective of this invention. it can.
