JP-A-7-257571
A transport container having at least one side wall opened and a side plate detachably provided in the opening is conventionally known from Patent Document 1 described above. Further, a transportable container that is configured to be foldable and has a side plate that is detachably provided is known from Patent Document 2 described above. These transport containers have an advantage that articles can be taken in and out of the opening even when they are stacked in multiple stages.
[0004]
[Problems to be solved by the invention]
By the way, the transport container described in Patent Literature 1 has a protrusion formed on the inner edge of the opening for detachably engaging the side plate. For this reason, there is a problem in that the projections hinder an article from being put in and taken out of the container.
Further, the transport container described in Patent Document 2 has an engaging portion urged by an elastic body such as a coil spring on a side plate, and the engaging portion moves in and out of an end surface of the side plate by operating a knob. And the side plate is detachably engaged. Therefore, there is a problem that the structure is complicated and the manufacturing cost is increased.
[0005]
Therefore, the present invention is to solve the problems of these conventional transport containers in which the side plates are detachable.
[0006]
[Means for Solving the Problems]
For this purpose, the transport container of the present invention is detachably mounted on a container main body having a pair of side walls provided so as to face each other by standing upright from the bottom plate, and a side opening edge of the container main body. A transport container comprising a side plate, a sliding groove formed in a longitudinal direction on the inner surface of both side edges of the side plate, and an engaging piece is folded back into the sliding groove at an outer edge of the sliding groove. An opening is formed in the end face of the side wall so that the engaging piece can be loosely fitted therein so as to open over the outer surface of the side wall. The sliding groove is formed so as to open to the outer surface of the side wall.
Therefore, no irregularities or the like for engagement are formed on the inner surface of the side wall, and the article can be smoothly taken in and out.
[0007]
Further, the present invention is characterized in that, in the above-mentioned transport container, the ceiling surface of the introduction port is formed in an inclined surface shape which becomes higher as going to the inner part.
For this reason, when the side plate is lifted right above, the engagement piece hits the ceiling surface and is guided in the depth direction, so that the side plate is unlikely to come off.
[0008]
Further, according to the present invention, in the transport container, an upper engaging piece is formed at an inner edge of the sliding groove so as to protrude into the sliding groove, and the upper engaging piece is fitted to an upper end of the side wall. It is characterized by forming a groove.
For this reason, the state of attachment of the side plate becomes more firm.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view of a plastic transport container according to the present invention, FIG. 2 is a perspective view of a container body of the transport container, FIG. 3 is a perspective view of an outer surface of a side plate of the transport container, and FIG. It is a perspective view of the inner surface of a side plate. As shown in FIG. 2, the container body 1 is integrally formed on both long sides of a rectangular bottom plate 2 so that a pair of rectangular side walls 3 stand upright. It is open. Reference numeral 4 denotes a reinforcing rib formed on the outer surface of the side wall 3. As shown in FIGS. 1, 3 and 4, reference numeral 5 denotes a rectangular side plate which is detachably attached to a side opening edge of the container body 1. Reference numeral 6 denotes a reinforcing rib formed on the outer surface of the side plate 5.
[0010]
The side plate 5 is formed with sliding grooves 7 extending vertically in the inner surfaces of both side edges, and engaging pieces 8 are respectively formed on the outer edges of the sliding grooves at the lower portion of the side plate 5 so as to be folded back into the sliding grooves. It is formed so that it becomes. Reference numeral 9 denotes a through-hole that is necessarily formed at the bottom of the slide groove to form the engagement piece 8 by injection molding. Reference numeral 10 denotes a hook-shaped upper engaging piece formed on the upper inner edge of the sliding groove 7 so as to protrude into the sliding groove, and 11 denotes the upper engaging piece 10 formed by injection molding. The through hole is necessarily formed at the bottom of the sliding groove. The lower part of the sliding groove 7 is open downward, the upper part is closed by a horizontal part 12, and a hook-like part 13 is formed at the tip of the horizontal part. A pair of wedge-shaped protrusions 14 and a pair of protrusions 15 are formed on the lower edge of the side plate 5.
[0011]
On the other hand, as shown in FIG. 2, the container body 1 has an inlet 21 into which the engaging piece 8 can be loosely fitted to the end face 20 of the side wall 3 of the container body 1 so as to open over the outer surface of the side wall. The engaging groove 22 is formed so as to open downward on the outer surface of the side wall so as to extend downward from the inner part of the inlet, so that the engaging piece 8 can slide in the engaging groove. ing. In addition, the ceiling surface 23 of the inlet 21 is formed in the shape of an inclined surface that becomes higher as it goes deeper. Reference numeral 24 denotes a vertical groove formed so that the upper engagement piece 10 can be fitted to the upper end of the edge of the side wall 3. Reference numeral 25 denotes a concave portion formed near both ends of the upper side of the side wall 3, and reference numeral 26 denotes a locking hole formed in the upper side of the side wall 3. Reference numerals 27 and 28 denote engagement holes formed on the upper surfaces of both end edges of the bottom plate 2.
[0012]
In this transport container, when the side plate 5 is attached, the engaging piece 8 is inserted into the inlet 16 so that the end face 20 of the side wall 3 of the container body 1 enters the slide groove 7 of the side plate 5 as shown in FIG. The side plate 5 is lowered in this state, and the engaging piece 8 is slid into the engaging groove 17 to engage with the side plate 5 as shown in FIG. At this time, the upper engaging piece 10 fits into the vertical groove 24, the protruding piece 14 fits into the engaging hole 27, the protruding piece 15 fits into the engaging hole 28, and the hook-like portion 13 25 fits loosely. As described above, since the side plate 5 engages the engagement piece 8 with the engagement groove 17 on the outer surface of the side wall 3, unevenness for engagement is not formed on the lower inner surface of the side wall 3. , Articles can be smoothly put in and out. Moreover, since the edge of the side wall 3 is held by both side edges of the side plate 5, the side wall 3 is reinforced and rigid by attaching the side plate 5.
[0013]
In addition, since the side plate 5 is attached by sliding the engaging piece 8 into the introduction port 16 at the intermediate height and then sliding downward, the dimensional accuracy of the interval between the side walls 3 is reduced due to unavoidable deformation in plastic molding. At worst, it can be easily attached. In other words, since the engagement piece 8 is first loosely fitted into the introduction port 16 of the intermediate height portion where the deformation amount is relatively small, and then the engagement piece 8 is moved downward, the side plate is always attached. Becomes easier.
Further, the container body and the side plate can be integrally formed of plastic, respectively, and the number of components is extremely small, so that the manufacturing cost can be reduced.
[0014]
Also, by lifting the side plate 5 upward, the engagement piece 8 is disengaged from the engagement groove 17 and the upper engagement piece 10 comes out of the vertical groove 24. Can be easily removed. The detached side plate 5 can also be placed on the outer side surface of the side wall 3 by hooking the hook-like portion 13 on the locking hole 26.
[0015]
In addition, since the ceiling surface 23 of the inlet 21 is formed in an inclined surface shape that becomes higher as going to the depth, as shown in FIG. It is guided in the depth direction on the surface 23, and the side plate 5 does not come off in the front. For this reason, even if an operator raises the side plate 5 by mistake during transportation, the side plate 5 does not come off easily, and safety is increased.
[0016]
In this embodiment, only one engaging piece 8 is formed in each sliding groove 7. However, in a container having a higher height, a plurality of engaging pieces 8 are formed at appropriate intervals in the vertical direction, and By forming a plurality of openings 21 and engagement grooves 22 correspondingly, the mounting state of the side plate can be made more firm.
[0017]
Further, in this embodiment, the case where the side wall of the container main body is formed integrally with the bottom plate has been described, but the present invention can also be applied to a container whose side wall is foldably provided on the bottom plate.
Further, in this embodiment, a case where two side walls are opened is described, but it is needless to say that the present invention can be applied to a container having one side wall opened.
[0018]
【The invention's effect】
As described above, the transport container of the present invention has a sliding groove formed in a longitudinal direction on the inner surface of both side edges of the side plate, and an engaging piece is folded back into the sliding groove at an outer edge of the sliding groove. And an introduction port into which the engagement piece is loosely fitted is opened at the end face of the side wall of the container body so as to open over the outer surface of the side wall, and the introduction port is formed downward from a deep portion of the introduction port. Since the engagement groove in which the engagement piece slides is opened on the outer surface of the side wall, no projection or the like for engagement is formed on the inner surface of the side wall, and there is no obstruction, so that articles can be smoothly taken in and out. In addition, in the mounted state, the edge of the side wall is held by the both side edges of the side plate, so that the side wall is made firm, and further, there is a beneficial effect that the structure is simple and the manufacturing cost is reduced.
