DESCRIPTION OF SYMBOLS 100 Container main body 110 Bottom wall 111 Insertion hole 200 Partition plate 230 1st latching | locking part 300 Container with a partition

Embodiments of the present invention will be described below with reference to the drawings. In the present specification, “upward” refers to the upward direction in the vertical direction when placed on a horizontal surface with the opening surface of the container body of the partitioned container facing upward, Is the downward direction in the vertical direction.

  First, the container main body 100 of the container 300 with a partition of this invention is shown in FIG. 1A is a plan view of the container body 100, FIG. 1B is a cross-sectional view taken along the line AA, and FIG. 1C is a cross-sectional view in which the periphery of the insertion hole 111 in FIG. 1B is enlarged. 1 (d) shows a cross-sectional view along the line BB.

  The container body 100 includes a bottom wall 110, a front wall 120, a rear wall 130, a side wall 140, and a side wall 150 erected so as to surround the bottom wall 110. The front wall 120 and the rear wall 130 that face each other are parallel to each other, and the side wall 140 and the side wall 150 that face each other are also parallel to each other.

  Further, a linear insertion hole 111 extending in the longitudinal direction is formed near the center of the bottom wall 110. The insertion hole 111 is configured to be able to insert a partition plate 200 to be described later, and the width (length) L7 of the insertion hole 111 in the longitudinal direction is a width L5 (upper side of the partition plate 200). As described above, the width of the insertion hole 111 in the short direction is equal to or greater than the thickness of the main body 210 of the partition plate 200.

  The bottom wall 110 is formed with an elongated sandwiching piece 161 and a sandwiching piece 162 so as to sandwich the insertion hole 111 from both sides. The sandwiching piece 161 and the sandwiching piece 162 are parallel to each other, and constitute a partition plate sandwiching section 160 that sandwiches a partition plate 200 described later.

  Further, as shown in FIG. 1C, the recess 113 on the outer surface of the bottom wall 110 is formed in a long shape along both sides of the insertion hole 111. The recess 113 is a portion where the first locking portion 230 of the partition plate 200 comes into contact when the partition plate 200 is inserted into the container body 100 as will be described later. The outer surface of the first locking part 230 and the outer surface of the bottom wall 110 are configured to be flush with each other with the first locking part 230 in contact with the recess 113.

  Further, sandwiching pieces 171 and 172 are formed on the inner surfaces of the left and right side walls 140 and 150. The sandwiching piece 171 and the sandwiching piece 172 are formed in a long shape so as to extend upward from both ends of the insertion hole 111. And this clamping piece 171 and the clamping piece 172 are arrange | positioned mutually parallel, and form the groove | channel, The edge part 211 of the partition plate 200 mentioned later is inserted | pinched by the said groove | channel. Therefore, the sandwiching piece 171 and the sandwiching piece 172 serve as a partition plate sandwiching portion 170 that sandwiches a partition plate 200 described later. Note that the partition plate sandwiching portion 170 may be partially formed on the inner surface of the side wall 140 or the side wall 150.

  The container body 100 is manufactured by injection molding in which a synthetic resin such as PP is melted and poured into a mold. Specifically, the molten synthetic resin is poured into a space between a cavity (fixed side template) that forms the outside of the container body 100 and a core (movable side template) that forms the inside of the container body 100. . Next, the completed container body 100 is taken out by moving the core to the side facing the cavity and pulling it out. In addition, an opening 112 wider than the insertion hole 111 is formed as a gate for pouring synthetic resin into the space between the cavity and the core. The synthetic resin is poured from the end of the opening 112 of the bottom wall 110 of the container body 100 to prevent the remaining gate cut from being formed on the bottom wall 110.

  Here, in order to make it easy to extract the container main body 100 from the core, as shown in FIG. 1D, the widths of the opposing side wall 140 and the side wall 150 gradually increase from the lower end toward the upper end. . Therefore, the width L1 on the upper end side is slightly wider than the width L2 on the lower end side. Similarly, as shown in FIG. 1B, the interval between the clamping piece 171 and the clamping piece 172 of the partition plate clamping unit 170 gradually increases from the lower end toward the upper end. Therefore, the width L3 on the upper end side of the groove of the partition plate clamping portion 170 is slightly wider than the width L4 on the lower end side. In addition, the container main body 100 is a vertical surface because the mold is removed, but the inner surface is gradually formed thicker from the upper end toward the lower end.

  Next, the partition plate 200 of the container 300 with a partition of this invention is shown in FIG. 2A is a plan view of the partition plate 200, FIG. 2B is a front view of the partition plate 200, FIG. 2C is a cross-sectional view taken along the line CC, and is an enlarged cross-sectional view of the periphery of the edge 211, 2D is a cross-sectional view taken along the line DD, and is an enlarged cross-sectional view around the edge 211, FIG. 2E is a cross-sectional view taken along the line EE, and FIG. 2F is a first view in FIG. It is sectional drawing which expanded the latching | locking part 230 periphery.

  First, the partition plate 200 is a plate member integrally formed of a synthetic resin, and includes a flat main body 210 and a handle 213 formed so as to protrude from the upper end of the main body 210. A handle hole 214 is formed in the handle 213 so that the handle 213 can be easily gripped by a human finger, and a thick portion 215 is formed at the periphery of the handle hole 214. Note that the thickness of the thick portion 215 is thinner than the width of the insertion hole 111 (the width in the short direction between the front wall 120 and the rear wall 130) of the portion where the partition plate clamping portion 160 is not formed. ing. Moreover, you may provide the partition plate clamping part 160 in the insertion hole 111 corresponding to the position where the thick part 215 is inserted.

  The main body 210 is sized to be inserted into the container main body 100 and accommodated. Specifically, the main body 210 has a substantially trapezoidal shape when viewed from the front, and the horizontal width of the main body 210 gradually increases from the lower end toward the upper end. The width L5 on the upper end side is slightly wider than the width L6 on the lower end side. The main body 210 has a substantially trapezoidal shape when viewed from the front, so that both side surfaces thereof are inclined. However, the present invention is not limited to this, and the main body portion 210 has a square shape when viewed from the front or a rectangular shape when viewed from the front. It may be vertical.

  The main body 210 is a plate member having a uniform thickness, and includes thick portions 220 that are thicker than the main body 210 at both ends. The thick portion 220 is formed in an elongated shape in the vertical direction inside the edge portion 211. Further, the thickness of the thick portion 220 is larger than the width of the groove of the partition plate holding portion 170, that is, the width between the holding piece 171 and the holding piece 172.

  As shown in FIG. 2C, the surface of the thick portion 220 is an inclined surface 223 so that the thickness gradually increases from the inner end 221 toward the outer end 222. As will be described later, the outer end 222 of the thick portion 220 is formed to extend in the vertical direction so as to follow the partition plate clamping portion 170 of the container body 100 when the partition plate 200 is inserted into the container body 100. Has been.

  Further, as shown in FIG. 2B, an extended thick portion 224 that extends from the outer end 222 toward the edge 211 is formed on the upper end side of the thick portion 220. As shown in FIG. 2D, the thickness of the extended wall thickness part 224 is larger than that of the main body part 210. As will be described later, the extended thick portion 224 can be inserted between the sandwiching piece 171 and the sandwiching piece 172 of the partition plate sandwiching portion 170 when the partition plate 200 is inserted into the container main body 100. Furthermore, it extends toward the partition plate clamping part 170.

  In addition, a flat first locking portion 230 is formed at the lower end of the partition plate 200 continuously in a straight line in the longitudinal direction of the main body portion 210. As shown in FIGS. 2E and 2F, the first locking portion 230 is formed so as to protrude from the main body portion 210 in the horizontal direction. When inserted into the container body 100, the insertion hole 111 can be closed. Further, as shown in FIG. 2A, a wider portion 231 wider than the first locking portion 230 is formed near the center of the first locking portion 230, and the partition plate 200 serves as the container body 100. The wide portion 231 has a size capable of closing the opening 112 of the bottom wall 110 of the container body 100 when inserted into the container. Note that the wide portion 231 may not be formed. Further, although the first locking portion 230 is integrally formed with the main body portion 210, it may be formed separately from the main body portion 210 and attached to the main body portion 210.

  A second locking portion 240 is formed at the lower end of the partition plate 200 at a predetermined interval above the first locking portion 230. As shown in FIGS. 2 (e) and 2 (f), the second locking portion 240 is formed so as to protrude from the surface of the main body 210, and has an inclined surface 241 that is inclined toward the main body 210. And a flat surface 242 extending in the horizontal direction. As will be described later, when the partition plate 200 is inserted into the container body 100, the flat surface 242 of the second locking portion 240 can be locked to the upper end edge of the partition plate clamping portion 160.

  Next, the process of assembling the partition plate 200 to the container body 100 of the present invention and manufacturing the partitioned container 300 will be described with reference to FIG. 3A is an overall perspective view showing a state before the partition plate 200 is assembled to the container body 100, and FIG. 3B is an overall perspective view showing a state after the partition plate 200 is assembled to the container body 100. It is.

  First, as shown to Fig.3 (a), the container main body 100 and the partition plate 200 which heat cooled are prepared. The container body 100 is not cooled completely after being manufactured by the above-described injection molding, and is in a state in which the shrinkage change is large while retaining the heat at the time of injection molding to such an extent that it can be elastically deformed by an external force.

  Then, the partition plate 200 is inserted into the container main body 100 from the outside of the bottom wall 110 of the container main body 100 through the insertion hole 111. Then, as shown in FIG. 3B, when the first locking portion 230 of the partition plate 200 is locked to the bottom wall 110 of the container body 100, the partition plate 200 can no longer be inserted, and the partitioned container 300 is Complete. In the state where the container 300 with a partition is completed, as will be described later, the partition plate 200 is fixed inside the container body 100, and the handle 213 of the partition plate 200 protrudes to the outside of the container body 100.

  Next, the completed partitioned container 300 will be described in more detail with reference to FIGS. 4 and 5. 4A is a front view of the container 300 with a partition, FIG. 4B is a cross-sectional view taken along the line FF, and FIG. 4C is a cross-sectional view in which the periphery of the first locking portion 230 in FIG. It is. 5A is a cross-sectional view taken along the line GG shown in FIG. 4A, and is an enlarged cross-sectional view of the periphery of the edge 211. FIG. 5B is a cross-sectional view of H shown in FIG. FIG. 11 is a cross-sectional view of H-section, in which the periphery of the edge 211 is enlarged.

  First, as shown in FIG. 4B, the edge 211 of the partition plate 200 is inserted into the groove of the partition plate sandwiching portion 170, and the partition plate 200 is sandwiched by the partition plate sandwiching portion 170. 200 does not rattle in the front-rear direction (the direction of the front wall 120 or the rear wall 130 of the container body 100).

  Further, as shown in FIG. 4C, the first locking portion 230 at the lower end of the partition plate 200 is locked to the outer surface side of the bottom wall 110 of the container body 100, so that the partition plate 200 is moved upward. Never move. Further, since the flat surface 242 of the second locking portion 240 of the partition plate 200 is locked to the upper end of the sandwiching piece 161 and the sandwiching piece 162 of the partition plate sandwiching portion 160, the partition plate 200 moves downward. There is nothing. Therefore, the partition plate 200 is fixed to the container body 100 by the first locking portion 230 and the second locking portion 240 so as not to move up and down. The first locking part 230 and the second locking part 240 constitute a fixing part that fixes the partition plate 200 to the container body 100.

  When the partition plate 200 is inserted into the container body 100 and fixed, the container body 100 having a large shrinkage change retains heat at the time of injection molding to such an extent that it can be elastically deformed by an external force, and contracts larger than the designed product dimensions. Since the change is large, the second locking portion 240 is elastically deformed so as to push and widen the insertion hole 111 of the bottom wall 110 and the holding pieces 161 and 162 of the partition plate holding portion 160, while the container main body 100. It is inserted into the inside. And after the container 300 with a partition is completed, when the container main body 100 shrinks | contracts, it will be according to the design product dimension. Then, as shown in FIG. 4C, the holding pieces 161 and 162 of the partition plate holding portion 160 and the lower end side of the main body portion 210 are assembled without a gap, and the play of the partition plate 200 is not loose. Effectively prevented.

  Since the upper side of the second locking portion 240 is an inclined surface 241, when the partition plate 200 is inserted into the container body 100, the insertion hole 111 or the partition plate is sandwiched between the bottom wall 110 and the second locking portion 240. It is easy to spread the portion 160. Moreover, since the lower part of the 2nd latching | locking part 240 is the flat surface 242, it can latch firmly with the upper end of the partition plate clamping part 160, and the partition plate 200 becomes difficult to pull out below.

  Further, in the design product dimensions, the inner width between the side wall 140 and the side wall 150 of the container main body 100 is equal to or slightly wider than the width of the main body 210 of the partition plate 200. When the partition plate 200 is inserted and fixed in the container body 100, the container body 100 having a large shrinkage change retains heat during injection molding to such an extent that it can be elastically deformed by an external force, and contracts larger than the designed product dimensions. Since the change is large, the main body 210 of the partition plate 200 can be easily inserted between the side wall 140 and the side wall 150 of the container main body 100 and accommodated. Furthermore, when the container main body 100 contracts after the container 300 with partitions is completed, the product dimensions are as designed, so that the main body 210 of the accommodated partition plate 200, the side wall 140 and the side wall 150 of the container main body 100 are The space between the container body 100 and the partition plate 200 can be assembled with high accuracy because there is no space between them or a space between them.

  Next, as shown in FIG. 5A, the edge portion 211 of the inserted partition plate 200 is sandwiched between the sandwiching piece 171 and the sandwiching piece 172 of the partition plate sandwiching portion 170, and in this state, the partition plate sandwiching is performed. The thick part 220 is located inside the part 170. For this reason, even when a container X having a small thickness, such as paper, is stored in the container body 100, the thick portion 220 blocks the front of the gap Y between the partition plate sandwiching portion 170 and the edge portion 211. The contained material X does not get caught in the gap Y. Furthermore, since the thick portion 220 includes an inclined surface 223 that is inclined from the inner end 221 toward the outer end 222, the accommodation X is accommodated along the inclined surface 223. Therefore, since the end portion of the object X is guided in the direction away from the gap Y, it is possible to more reliably prevent the entry X from being caught in the gap Y.

  Next, as shown in 170 in FIG. 5 (b), the groove width L3 of the partition plate clamping portion 170 on the upper end side of the container body 100 is equal to the groove width L4 of the partition plate sandwiching portion 170 on the lower end side (FIG. 5 ( It is slightly wider than a). This is for facilitating extraction of the core during injection molding as described above. Therefore, as shown in FIG. 5 (b), a gap is formed between the partition plate clamping portion 170 and the edge portion 211 of the partition plate 200 on the upper end side of the container body 100, which causes the partition plate 200 to be loose. However, on the upper end side of the container main body 100, the extended thick portion 224 of the partition plate 200 enters the groove of the partition plate sandwiching portion 170. Therefore, the gap between the partition plate clamping portion 170 and the edge portion 211 is filled, and the partition plate 200 does not rattle.

  Thus, according to the container 300 with a partition of this invention, since the fixing part which can fix the partition plate 200 is provided, the partition plate 200 will fall up and down at the time of the storage of the container 300 with a partition, the time of conveyance, etc. Can be prevented. In particular, due to the structure in which the first locking portion 230 of the partition plate 200 inserted from the lower side of the container body 100 is locked to the outer surface side of the bottom wall 110 of the container body 100, the partition plate 200 is pulled upward. This is effectively prevented.

  Specifically, in the prior art, because of the structure in which the partition plate is inserted and fixed from above, the partition plate is inevitably easily pulled upward. However, in the partitioned container 300 of the present invention, the first locking portion 230 on the lower end side of the partition plate 200 is locked to the outer surface side of the bottom wall 110 of the container body 100 by inserting the partition plate 200 from below. Further, since it is a structure that is not inserted upward, it is possible to structurally prevent the partition plate 200 from moving upward and coming off. As a result, it is possible to effectively prevent the partition plate 200 from being pulled upward and the partitioned container 300 from being disassembled.

  In addition, when the conventional container with a partition needs to lift, it needs to have a container main body with both hands, and if there was a partition plate, there existed a possibility of pulling out upwards. However, according to the partitioned container 300 of the present invention, when the partition plate 200 is attached from the bottom surface 110 side of the container main body 100, it is possible to prevent upward pulling when it is lifted. Further, by providing the handle 213 at the center position of the partition plate 200, it is possible to have a good balance with one hand.

  Furthermore, according to the partitioned container 300 of the present invention, the fixing portion is locked to the outer surface side of the bottom wall 110 of the container body 100 and the first locking portion 230 to be locked to the inner surface side of the bottom wall 110. It is comprised from the two latching | locking parts 240. FIG. Therefore, the partition wall 200 can be firmly fixed to the container body 100 by sandwiching the bottom wall 110 from the inside and outside between the first locking portion 230 and the second locking portion 240.

  Furthermore, according to the partition-equipped container 300 of the present invention, the partition plate clamping portions (160, 170) that sandwich the inserted partition plate 200 are formed, so that the partition plate 200 rattles within the container body 100. There is no.

  In addition, as shown in FIG. 1, although the partition plate clamping part 160 and the partition plate clamping part 170 were provided in the bottom wall 110 of the container main body 100, the side wall 140, and the side wall 150, it is not limited to this, A partition plate If it is possible to prevent 200 from rattling in the container main body 100, a partition plate clamping portion may be provided only on a part of the inner surface of the container main body 100, for example, only on the bottom wall 110 or only on the side wall 140 and the side wall 150. . However, as shown in FIG. 1, by providing the partition plate clamping portion 160 on the bottom wall 110 of the container body 100, the effect of improving the strength of the bottom wall 110 of the container body 100 can be obtained.

  Moreover, as shown in FIG. 4, the 2nd latching | locking part 240 latched to the upper end of the partition plate clamping part 160, and the partition plate 200 was prevented from moving below, However, It is not limited to this. For example, the second locking portion 240 only needs to be able to be locked to a part of the bottom wall 110 of the container body 100 from the inside. Therefore, when the partition plate clamping portion 160 is not provided on the bottom wall 110, the second locking portion 240 is used. The shape of the second locking portion 240 may be changed such that the second locking portion 240 can be locked by directly contacting the inner surface of the bottom wall 110.

  As shown in FIG. 4, the fixing portion that fixes the partition plate 200 to the container main body 100 so as not to move up and down is composed of the first locking portion 230 and the second locking portion 240. It is not limited to this. For example, in FIG. 5A, if the partition plate clamping unit 170 firmly holds the edge 211 of the partition plate 200 to such an extent that the partition plate 200 cannot be easily moved downward, the fixing unit You may comprise with the partition plate clamping part 170 and the 1st latching | locking part 230. FIG. In that case, in the designed product dimensions, the edge 211 is press-fitted into the groove of the partition plate holding portion 170 by making the thickness of the edge 211 larger than the width of the groove of the partition plate holding portion 170. Thus, the partition plate clamping portion 170 may firmly clamp the edge portion 211. Further, by applying an adhesive or the like to the contact surface between the partition plate sandwiching portion 170 and the edge portion 211 and firmly fixing both, the partition plate sandwiching portion 170 firmly sandwiches the edge portion 211. Also good.

  Further, a locking claw may be provided on the inner surface of the side wall of the container main body 100, and a locking recess for locking to the locking claw may be provided on the edge portion 211 of the partition plate 200. Then, the partition plate 200 inserted into the container main body 100 cannot move downward due to the locking recesses of the edge 211 and the locking claws on the inner surface of the side wall of the container main body 100 being locked. In that case, the fixing portion is configured by the locking structure including the locking claw and the locking recess and the first locking portion 230 of the partition plate 200.

  In the partitioned container 300 of the present invention, the partition plate 200 is not rattled by both the partition plate clamping portion 160 on the bottom surface side of the container body 100 and the partition plate clamping portion 170 on the side surface side of the container body 100. Although pinched, it is not limited to this. For example, as long as the partition plate sandwiching section 160 grips the partition plate 200 so as not to rattle, there is no problem even if there is a slight backlash between the partition plate 200 and the partition plate sandwiching section 170. On the other hand, as long as the partition plate holding portion 170 holds the partition plate 200 so as not to rattle, there is no problem even if there is some backlash between the partition plate 200 and the partition plate holding portion 160.

  Moreover, the partition plate 200 of the container 300 with a partition of the present invention may be provided with a partition wall orthogonal to the main body 210 to secure a space for accommodating a small container or the like in the container 300 with a partition.

Further, in the present invention, “a method for producing a container with a partition made of a synthetic resin including a container body and a partition plate,
After the container body is manufactured by injection molding, it is not completely cooled, and it can be elastically deformed by external force, in a state of large shrinkage change while retaining heat at the time of injection molding,
Insert the partition plate from the outside of the bottom wall of the container body into the insertion hole provided in the bottom wall of the container body,
The inserted partition plate is fixed to the container body by the partition plate or the fixing portion provided in the container body,
Part of the fixing by the fixing portion is performed by a first locking portion provided on the lower end side of the partition plate being locked to the outer surface side of the bottom wall of the container body. .

  Due to this feature, when the partition plate 200 is inserted and fixed to the container body 100, the container body 100 having a large shrinkage change retains heat at the time of injection molding to such an extent that it can be elastically deformed by an external force, and is larger than the designed product dimensions. Therefore, the partition plate 200 can be easily inserted into the container body 100 through the insertion groove 111. Furthermore, when the container main body 100 contracts after the container 300 with partitions is completed, the product dimensions are as designed, so that the container main body 100 and the partition plate 200 are assembled with high accuracy.

The partitioned container of the present invention is not limited to the above-described examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments, and these modifications Combinations are also included in the scope of rights.
