Description

  The present invention relates to a stackable and nestable container that can be raised according to the size and height of stored items by attaching it to the upper edge of a plastic container capable of stacking and nesting as required. The present invention relates to the structure of the raising frame.

In Patent Document 1 below, a container is attached to the upper edge of an existing container according to the size and height of the stored item, whereby the capacity of the container is adjusted and the container is raised to improve the use efficiency of the container. A frame is disclosed.
Utility Model Registration No. 2521865

  On the other hand, it is a plastic container in which a pocket is formed by expanding a part of the side wall outward, and the upper container is rotated 180 degrees in the horizontal plane or rotated with respect to the lower container. Containers for logistics that can be stacked in multiple stages (stacking), or stacked with the lower half of the upper container inserted into the lower container (nesting) and reduced in volume when not in use. As is well known.

By the way, when the conventional raised frame is attached to a plastic container capable of stacking and nesting as described above, there is a problem that nesting cannot be performed because the pocket portion is sealed by the raised frame.
In addition, it was considered to form a cut portion in the raised frame so that the pocket portion is not sealed, but in such a case, the strength of the frame is weakened, and it is particularly easy to deform because it is plastic molded. There is a problem that superimposition with can not be performed well.
In addition, stacking work is usually performed by placing the upper container on the lower container and then horizontally stacking the upper container, but with the raised frame attached When the stacking operation is performed, a large lateral load is applied to the raised frame during sliding, which may cause the raised frame to be displaced outward or detached.
The present invention seeks to provide a container capable of stacking and nesting that can solve such problems and a frame for raising the container.

For this purpose, the invention according to claim 1 forms a pocket portion by bulging at least two of the opposite side walls outward, and rotates the upper container 180 degrees within the horizontal plane relative to the lower container. Alternatively, by placing the container without rotation, the upper container is stacked on the upper edge flange of the lower container, or the container is stacked with the substantially lower half of the upper container inserted into the lower container. In addition, a positioning hole and an engagement hole are formed between the pocket portions of the upper edge flange near the pocket portions, respectively, and the pocket portion is sealed by forming a notch portion matching the pocket portion on the inner peripheral edge. A frame that overlaps the upper edge flange of the container without being connected, and each side of the frame is connected so that the upper flange and the lower flange have a U-shaped cross section. And than, characterized in that by forming a hook-like projections for engaging the tapered shaft-like guide projections and the engaging hole is fitted into the positioning hole on the lower surface of the lower flange.
For this reason, even if the frame is slightly deformed, it is securely mounted on the upper edge flange of the container without fear of shifting or coming off.

According to a second aspect of the present invention, a positioning hole and an engagement hole are formed in the upper flange of the frame in the same position and shape as the positioning hole and the engagement hole provided in the upper edge flange of the container. And
For this reason, if necessary, the same frame can be stacked and mounted, and the volume can be raised according to the size and height of the stored items.

According to a third aspect of the present invention, a central portion of each side of the raising frame is formed in a U-shaped cross section that opens downward.
For this reason, there is no possibility that the operator's hand is put on the raising frame and lifted, and there is no possibility that the frame will come off and the container will drop off.

  By mounting the raising frame, the original function of the container that stacking and nesting are possible is not impaired. Therefore, if this raising frame is attached, even a container that can be stacked and nested can be raised according to the size and height of the stored items. For this reason, the utilization efficiency and application range of the container can be enhanced.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a plastic container according to the present invention. In the container A, an upper edge flange 1 is integrally formed on the entire periphery of the upper end opening edge, a reinforcing flange 2 is integrally formed on the lower side of the upper edge flange, and a part thereof is formed on the opposing long side walls 3a and 3b. Are bulged outwardly to form pockets 4a, 5a, 4b, 5b that are approximately half the depth of the container A, spaced apart from each other by a predetermined distance. A support leg 6b is formed on the outer surface of the long side wall 3b so as to be point-symmetric with the pocket portion 4a, and a support leg 7b is formed on the outer surface of the long side wall 3b so as to be point-symmetric with the pocket portion 5a. A support leg 7a is formed on the outer surface of the long side wall 3a so as to be point-symmetric with 4b, and a support leg 6a is formed on the outer surface of the long side wall 3a so as to be point-symmetric with the pocket portion 5b. In addition, pocket portions 9a, 10a, 9b, 10b having a depth approximately half that of the container A are formed at predetermined intervals by causing a part of the short side walls 8a, 8b to bulge outward from each other. A support leg 11b is formed on the outer surface of the short side wall 8b so as to be point-symmetric with the pocket portion 9a, and a support leg 12b is formed on the outer surface of the short side wall 8b so as to be point-symmetric with the pocket portion 10a. A support leg 11a is formed on the outer surface of the short side wall 8a so as to be point-symmetrical, and a support leg 12a is formed on the outer surface of the short side wall 8a so as to be point-symmetrical with the pocket portion 10b.

  Therefore, the container A is placed on the upper edge flange 1 of the lower container by rotating the upper container without rotating the upper container with respect to the lower container, so that the support legs 6a, 6b, 7a, 7b, 11a of the upper container are placed. , 11b, 12a, and 12b are stacked in a multi-stage without stacking the container contents (stacking), and the upper container is rotated 180 degrees in the horizontal plane with respect to the lower container, so that the lower Each support leg 6a, 6b, 7a, 7b, 11a, 11b, 12a of the upper container formed in a point-symmetrical position in each pocket portion 4a, 5a, 4b, 5b, 9a, 10a, 9b, 10b When 12b is accommodated, the volume is reduced to about half the height (nesting).

  As shown in FIGS. 2 and 3, a circular positioning hole 13 and a rectangular engagement hole 14 are formed in a penetrating manner near both pockets between the pockets 4a and 5a of the upper edge flange 1, respectively. In addition, a positioning hole 15 and a rectangular engagement hole 16 having the same shape are formed in a penetrating manner near both pocket portions between the pocket portions 4b and 5b. A circular positioning hole 17 and a notched circular engagement hole 18 are also formed between the pocket portions 9a and 10a in a penetrating manner. In addition, a circular positioning hole 19 is formed between the pocket portions 9b and 10b in a penetrating manner, and a notched circular engagement hole 20 is formed in a penetrating manner outside the pocket portions 9b and 10b.

  Moreover, the side walls which adjoin each other in the form which cuts the inner periphery of the upper edge flange 1 in the four corner upper edges of this container A are protruded outward, and the step parts 21a-21d are formed. Moreover, the center part of the upper edge flange 1 located in the long side walls 3a and 3b is formed in a U-shape opening downward as shown in the cross-sectional shape in FIG. A finger can be hung. Reference numeral 22 denotes a central portion of the upper edge flange 1 for attaching a known card insert (for sandwiching a slip on which the product name, attribute, code number, barcode, etc. of the contents are inserted) to the outer surface of the long side wall 3a. It is the attachment hole formed in the through shape. Further, the inner surface of the long side wall 3b is formed in a concave shape as shown in FIG. 1 so that the card slot of the upper container does not collide with the inner surface of the lower container during nesting.

  On the other hand, FIG. 5 is a perspective view of the raising frame B superimposed on the upper edge flange 1 of the container A, and FIG. 6 is a perspective view when the frame B is turned upside down. The frame B is in the form of a rectangular frame having the same shape as the upper edge flange 1 of the container A, and each side has an upper flange 31 and a lower flange 32 connected in a U-shaped cross section. And the notch part 54a, 54b, 55a, 55b, 59a, 59b, 60a which matches each pocket part 4a, 4b, 5a, 5b, 9a, 9b, 10a, 10b of the said container A to the inner periphery of this flame | frame B is carried out. , 60b can be stacked on the upper edge flange of the container without sealing the pockets. In addition, tapered shaft guide protrusions 33, 35, 37, and 39 that fit into the positioning holes 13, 15, 17, and 19 are formed on the lower surface of the lower flange 32, and the engagement holes 14, 16, 18, and 20 are formed. The hook-shaped protrusions 34, 36, 38, 40 are formed to engage with each other.

  The upper flange 31 has positioning holes 43, 45, 45 in the same position and shape as the positioning holes 13, 15, 17, 19 and the engaging holes 14, 16, 18, 20 provided in the upper edge flange 1 of the container. 47, 49 and engagement holes 44, 46, 48, 50 are opened. The tapered shaft guide protrusions 33, 35, 37, and 39 protrude downward longer than the hook-shaped protrusions 34, 36, 38, and 40. Further, hanging pieces 51a to 51d that coincide with the step portions 21a to 21d are integrally formed on the inner peripheral edges of the four corners of the frame B, and the corresponding four corners of the frame B just above the hanging pieces 51a to 51d. Step portions 61a to 62d are formed on the inner periphery so as to cut the inner periphery in the same manner as the step portions 21a to 21d. In addition, it forms in the U-shaped cross-sectional shape which opens the center part of each edge | side of the flame | frame B below.

  For this reason, when mounting the frame B on the upper edge flange 1, the frame B is first placed on the upper edge flange 1 and pressed downward, so that the tapered shaft-shaped guide protrusions 33, 35, 37, and 39 are firstly pressed. Is inserted into the positioning holes 13, 15, 17, 19 and the taper surface of the guide projection is in sliding contact with the inner peripheral edge of the positioning hole. Even if the frame B is slightly deformed inward or inward, the horizontal component of the reaction force accompanying the sliding contact is lowered while the deformation of the frame B is corrected. 34, 36, 38, and 40 can be surely matched and engaged with the engagement holes 14, 16, 18, and 20. Note that the periphery of the positioning holes 13, 15, 17, 19 is formed thicker than the other portions as shown in the figure so as to withstand the pressing force.

  Further, since the positioning holes 13 and 15 and the engaging holes 14 and 16 are opened between the pocket portions 4a, 4b, 5a and 5b of the upper edge flange 1 near the pocket portions, the frame B which is easily deformed. It is possible to match the pockets 4a, 4b, 5a, and 5b with high accuracy without correcting the long sides of the cut portions 54a, 54b, and 55a, and in a stacking operation with the frame mounted. Even when a large lateral load is applied to the frame when the upper container is slid, there is no possibility that the frame is displaced or detached. For this reason, it is possible to greatly reduce the rate of product failure due to deformation of the frame B, or the rate of deformation or breakage due to use.

  Further, since the central part of each side of the frame B is formed in a U-shaped cross-sectional shape that opens downward, as shown in FIG. 10, when the frame is attached to the container A, the opening is formed in the container. Since the frame is closed by the upper surface, the frame is not put in hand during transportation work, and therefore there is no possibility of causing an accident that the frame is detached and the container is dropped.

  Further, since positioning holes 43, 45, 47, 49 and engagement holes 44, 46, 48, 50 are opened in the upper flange 31 of the frame B, a frame of the same shape is further added to the frame B as necessary. It can also be mounted in piles, and can be further raised according to the size and height of the stored items. For this reason, it is possible to further improve the utilization efficiency and application range of the container by attaching the necessary number of the raising frames.

  The present invention is not limited to the configuration shown in the above embodiment, and various modifications can be made. For example, the guide protrusions, positioning holes, hook-shaped protrusions, and engagement holes may be provided only on the upper edge flange of the container A and the long side of the frame B, and the number thereof is not limited to this embodiment.

  In the above embodiment, the container nesting is described by rotating the upper container by 180 degrees, but depending on the arrangement of the pocket portion, the upper container is stacked by rotating 180 degrees and without being rotated. A well-known container of a type that is nested by placing can also be structured to be able to mount a raising frame in the same manner as in the above embodiment according to the present invention.
