  Hereinafter, embodiments of the OA roller packaging container of the present invention will be specifically described with reference to the drawings.

  In the schematic plan view of one container 10 of the OA roller packaging container of one embodiment of the present invention shown in FIG. 1, the container 10 has a tray shape whose outer shape viewed from above is roughly rectangular. Yes. The container 10 has an accommodating portion 11 having a recess for accommodating the OA roller R. A side wall portion 12 is provided around the housing portion 11.

  The accommodating part 11 and the side wall part 12 are integrally molded from a synthetic resin sheet by vacuum molding. The container 10 has a draft angle for removing the container 10 from the mold after integral molding, but since the draft angle is slight, the draft angle is not shown in FIG. 1 and the following drawings. . When the container 10 does not contain the OA roller R, for example, during storage, the container 10 is partially nested by stacking a plurality of containers 10 up and down. Thereby, the container 10 can be stored compactly.

  Examples of the integral molding method for the container 10 include vacuum molding. However, it is not limited to vacuum forming. The synthetic resin used for the container 10 is not particularly limited as long as it is a material applicable to the OA roller packaging container. For example, polypropylene, polyethylene, polycarbonate, polyethylene terephthalate, polyacetal, and the like can be used.

  A plurality of OA rollers R are accommodated in the accommodating portion 11 in parallel. In the illustrated container 10, ribs 111 that individually partition the OA rollers R to be accommodated are formed, and the OA rollers R are individually accommodated between the ribs 111. The illustrated rib 111 is formed for each OA roller R.

  The concave portion 112 for accommodating the OA roller R in the accommodating portion 11 includes a functional body concave portion 112a corresponding to the functional body R1 of the OA roller R, a shaft concave portion 112b corresponding to the shaft R2 of the OA roller R, A shaft support portion 112c is provided between the functional body recess portion 112a and the shaft recess portion 112b and supports the shaft R2.

  The functional body recess 112a has a diameter of the functional body R1 so that the surface of the functional body R1 of the OA roller R does not contact the bottom surface of the functional body recess 112a when the OA roller R is accommodated in the container 10. It is a deeper dent. When the container 10 is stacked on the upper side of the container 20, which will be described later, the shaft recess 112b has a shaft R2 in which the back side of the shaft recess 112b is close to the shaft R2 of the OA roller R accommodated in the container 20. It is a dent of a depth that can prevent the vertical movement of. The shaft support portion 112c is formed with a groove 112d that supports the shaft R2 and restricts movement in the horizontal direction.

  The side wall portion 12 of the container 10 has a flange 121 that extends horizontally by connecting to the upper edge of the recess formed in the housing portion 11, and an outer wall 122 that extends downward from the outer peripheral end of the flange 121. The side wall portion 12 has a hollow cross-sectional shape that is convex upward by the flange 121 and the outer wall 122, and when the container 10 and the container 20 described later are stacked one above the other, The upper part of the side wall part 12 can enter the hollow part of the side wall part 12 of the upper container 10.

  The side wall portion 12 has at least one of two long sides and two short sides facing each other with the accommodating portion 11 interposed therebetween, and in the illustrated example, both the two long sides and the two short sides. A plurality of partial recesses 123 extending between the flange 121 and the outer wall 122 are formed. The concave portion 123 is formed in the vertical direction of the side wall portion 12 as shown in FIG. 2 as a schematic front view of the container 10 of FIG. 1 and as shown in FIG. It is a recessed part which has the bottom 123a in the middle.

  FIG. 4 shows a schematic plan view of one container 20 of the OA roller packaging container according to an embodiment of the present invention that is paired with the container 10 shown in FIG. The container 20 shown in FIG. 4 has a housing portion 11 having a recess for housing the OA roller R. A side wall portion 22 is provided around the housing portion 11. The accommodating part 11 and the side wall part 22 consist of synthetic resins, and are integrally formed by vacuum forming.

  The structure of the accommodating part 11 has the same structure as the accommodating part 11 of the container 10 shown in FIG. Therefore, the overlapping description is omitted. Further, like the container of FIG. 1, the side wall portion 22 is connected to the upper edge of the recess formed in the housing portion 11 and extends horizontally, and the outer wall 222 extends downward from the outer peripheral end of the flange 221. And has a hollow cross-sectional shape that is convex upward by the flange 221 and the outer wall 222. The side wall 2 is a partial recess extending over the flange 221 and the outer wall 222 on both of the two long sides and the two short sides facing each other with the accommodating portion 11 in between. A plurality of recesses 223 having a bottom 223a in the middle of the direction are formed.

  The container 20 shown in FIG. 4 is different from the container 10 shown in FIG. 1 in that the recess 223 provided in the side wall portion 22 of the container 20 is different from the recess 123 provided in the side wall portion 12 of the container 10. The point is that they are formed at different positions. Due to this difference, when the container 10 and the container 20 are stacked one above the other as described below, the upper container functions as a lid for the lower container.

  The OA roller packaging container 1 of this embodiment is a combination of a container 10 and a container 20. FIG. 5 shows a schematic front view of the container 10 shown in FIG. 1 and the container 20 shown in FIG. 4 stacked one above the other. When the upper container 10 and the lower container 20 are stacked, the upper part of the side wall part 22 of the lower container 20 enters the hollow space formed on the back side of the side wall part 12 of the upper container 10. At this time, the position of the partial recessed part 223 provided in the side wall part 22 of the lower container 20 and the position of the partial recessed part 123 provided in the side wall part 12 of the upper container 10 are different. Thus, the upper end of the side wall portion 22 of the lower container 20 abuts on the back side of the bottom surface 123a of the partial recess 123 of the side wall portion 12 of the upper container 10. Therefore, in this state, the back surface of the functional body recess 112a of the housing portion 11 of the upper container 10 does not come into contact with the functional body R1 of the OA roller R housed in the housing portion 11 of the lower container 20. Since the upper container 10 is configured to cover the upper surface of the lower container 20 while having a gap, the upper container 10 serves as a lid for the lower container 20. This eliminates the need to prepare a separate lid for the OA roller storage container, and eliminates the need to manufacture and use the lid, thus reducing the cost of transporting the OA roller using the OA roller storage container. Can be reduced.

  Moreover, since the outer wall of the side wall part of both containers overlaps when the container 10 and the container 20 are stacked, the packaging container 1 for OA rollers of this embodiment is a container when both are stacked. It is possible to prevent dust from entering between the container 10 and the container 20 from the outside.

  Further, each of the containers 10 and 20 of the OA roller packing container 1 according to the present embodiment includes the shaft recess 112b when the container 10 is stacked on the upper side of the container 20 with the shaft recess 112b. Since the back side of the OA roller has a depth close to the shaft R2 of the OA roller R accommodated in the container 20, it is possible to suppress the vertical movement of the shaft R2 of the OA roller R accommodated in the container 20. Therefore, the OA roller R can be stably conveyed.

  The OA roller packaging container 1 shown in FIG. 5 has a container 10 stacked on a container 20. However, the vertical relationship of the stacking of each container is not limited to the illustrated example, and even when the container 20 is stacked on the container 10, all the effects of the above-described OA roller packaging container 1 can be obtained. . In addition, the containers may be stacked in pairs of the container 10 and the container 20.

  In the illustrated OA roller packaging container 1 of the present embodiment, the side wall portions 12 and 22 in which the partial recesses 123 and 223 of the side wall portions 12 and 22 of the containers 10 and 20 have a substantially rectangular shape when viewed from above. However, it is provided on at least two sides of either the long side or the short side, so that the effect expected in the present invention can be obtained. However, it is preferable to provide it on the four sides as shown in the figure because it can surely serve as a lid when the containers are stacked up and down.

  The positional relationship between the partial recess 123 of the side wall 12 of the container 10 and the partial recess 223 of the side wall 12 of the container 20 is viewed from above when the container 10 and the container 20 are stacked up and down. Need not be completely misplaced. In short, when the container 10 and the container 20 are stacked one above the other, the bottom (123a or 223a) of the recess (123 or 223) of one container (10 or 20) is placed on the other container (20 or 10). It is sufficient that at least a part of the upper end of the side wall (22 or 12) abuts and the movement of the container can be suppressed so that the containers do not enter further.

  Furthermore, the shape of the partial recessed parts 123 and 223 formed in the side wall parts 12 and 22 of each container 10 and 20 is not limited to the shape shown in FIGS. The principal part of the container of the packaging container 1 for OA rollers of another embodiment of the invention is shown in FIG. In the container 30 of FIG. 6, the side wall portion 32 has a curved corrugated flange 321 and an outer wall 322 connected to the flange 321, and the upper side of the outer wall 322 is a curved surface to form a recess. It is. When the plurality of containers are stacked up and down, the corrugated phase of the side wall is different at the corresponding position of the side wall, or the period is different. The side walls corresponding to the lower container and the lower container are formed at different positions, and the same effects as those of the above-described embodiment can be obtained.

  It is preferable that the rib 111 provided in the container 11 of the container 10 or the container 20 has a height protruding from the bottom surface of the container 11 larger than the diameter of the functional body R1 of the OA roller R. This is because when the container 10 and the container 20 are vertically stacked and some external force is applied downward to the central portion of the upper container 10, the bottom surface of the container 1 of the upper container 10 is The ribs 111 of the container 20 are preferentially contacted so that the bottom surface of the container 1 of the upper container 10 is brought into contact with the surface of the functional body R1 of the OA roller R housed in the container 11 of the lower container 20. This is because contact can be effectively avoided.

  Further, the ribs 111 of the container 10 or the container 20 are formed by stacking the containers 10 and 20 up and down and the bottom surface 123a of the recess 123 of the side wall 12 of the upper container 10 is in contact with the upper end of the side wall 22 of the lower container 20. It is configured that the bottom surface of the accommodating portion 11 of the upper container 10 approaches or comes into contact with the upper end of the rib 111 of the lower container 20 when touching, so that some external force is applied downward to the upper container 10. In this case, it is more preferable because the deformation of the upper container 10 is suppressed.

  The OA rollers R housed in the containers 10 and 20 of the OA roller packaging container 1 of the present embodiment may have different dimensions or shapes of the shaft R2 protruding from both ends of the functional body R1. When such an OA roller R is accommodated, the size and shape of the shaft recess 112b of the accommodating portion 11 of each container 10 and 20 may be different depending on the shaft. However, it goes without saying that the OA roller packaging container 1 of the present embodiment can be configured to accommodate OA rollers having the same shaft dimensions or shapes.

  Next, an OA roller packaging container 2 according to still another embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a schematic plan view of one container 30 of the OA roller packaging container 2 according to this embodiment, and FIG. 8 is one container of the OA roller according to this embodiment that makes a pair with the container 30.

The shaft recess 312b of the storage portion 31 of FIG. The shaft support portion 312c of the housing portion 31 in FIG. 7 corresponds to the shaft support portion 112c of the housing portion 11 in FIG. The groove 312d of the shaft support portion 312c in FIG. 7 corresponds to the groove 112d of the shaft support portion 112c in FIG. Since each member of these accommodating portions 31 is the same in use and function except for a relative position with respect to each member of the accommodating portion 11, repeated description of the uses and functions is omitted.

  The container 40 in FIG. 8 has a tray shape whose outer shape viewed from above is roughly rectangular. The container 40 has an accommodating portion 41 having a recess for accommodating the OA roller R. A side wall portion 12 is provided around the housing portion 31. The side wall part 12 of FIG. 8 has the same configuration as the side wall part 12 of the container 10 shown in FIG. Therefore, below, the overlapping description about the side wall part 12 is abbreviate | omitted.

  The container 41 shown in FIG. 8 is the container shown in FIG. 1 in that the container 41 as a whole is located closer to one short side of the side wall 12 than the container 11 shown in FIG. It differs from the ten accommodating parts 11, and has the same structure except that point. In FIG. 8, the accommodating portion 41 is located closer to the short side on the left side of the drawing than the accommodating portion 11. The ribs 411 of the housing part 41 in FIG. 8 correspond to the ribs 111 of the housing part 11 in FIG.

Since each member of these accommodating portions 41 is the same in use and function except for a relative position with respect to each member of the accommodating portion 11, overlapping description will be omitted below.

  The OA roller packaging container 2 of the present embodiment is a combination of a container 30 and a container 40. FIG. 9 shows a schematic front view of the container 30 shown in FIG. 7 and the container 40 shown in FIG. 8 stacked one above the other. When the upper container 30 and the lower container 40 are stacked, the upper part of the side wall part 12 of the lower container 40 enters the hollow space formed on the back side of the side wall part 22 of the upper container 30. At this time, the position of the partial recessed part 123 provided in the side wall part 12 of the lower container 40 and the position of the partial recessed part 223 provided in the side wall part 22 of the upper container 30 are different. Thus, the upper end of the side wall portion 12 of the lower container 40 abuts on the back side of the bottom surface 223 a of the partial recess 223 of the side wall portion 22 of the upper container 30. Accordingly, in this state, the back surface of the functional body recess 312a of the housing portion 31 of the upper container 30 does not contact the functional body R1 of the OA roller R housed in the housing portion 41 of the lower container 40. Since the upper container 30 is configured to cover the upper surface of the lower container 40 while having a gap, the upper container 30 serves as a lid for the lower container 40. This eliminates the need to prepare a separate lid for the OA roller storage container, and eliminates the need to manufacture and use the lid, thus reducing the cost of transporting the OA roller using the OA roller storage container. Can be reduced.

  Moreover, since the outer wall of the side wall part of both containers overlaps when the container 30 and the container 40 are stacked, the packaging container 2 for OA rollers of this embodiment is a container when both are stacked. It is possible to prevent dust from entering between the container 30 and the container 40 from the outside.

  Furthermore, each of the containers 30 and 40 of the OA roller packing container 2 of the present embodiment has the shaft recess 312b when the container 30 is stacked on the upper side of the container 40 with the shaft recess 312b. Since the rear side of the shaft has a depth close to the shaft R2 of the OA roller R accommodated in the container 40, it is possible to suppress the vertical movement of the shaft R2 of the OA roller R accommodated in the container 40. Therefore, the OA roller R can be stably conveyed.
