Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stackable storage container for storing compact discs (CDs), cassette tapes, office papers, etc., more specifically, stacking storage containers of the same shape and size and a large container. The present invention relates to a storage container on which a medium-sized or small-sized storage container having substantially the same shape as the large-sized container but different dimensions can be stacked by changing the vertical and horizontal directions.

[0002]

2. Description of the Related Art A box-shaped storage container without a lid which is easily carried by a pair of handles is generally formed by forming a relatively wide overhang on the upper edge of the four peripheral walls of the container body. One box-shaped storage container is used to stack the other box-shaped storage container having the same shape and size. in this case,
In order to prevent the stacked upper storage containers from slipping sideways and collapsing, a ridge that can be fitted inside the overhanging edge is provided partially or annularly on the bottom of the container body, or on the bottom of the container body. A convex surface that fits inside the protruding edge is formed on itself.

On the other hand, in most of the handles provided in the storage container, the base ends facing each other of the handles are loosely fitted in the mounting holes provided in the opposing outer walls of the container body so as not to be detachable and rotatable. , The rotation range is not particularly limited, and is configured to rotate freely. Particularly, in the case of a storage container made of a rectangular parallelepiped, a U-shaped handle is provided in a mounting hole formed in the outer wall of the opposite long side. The base ends facing each other are loosely fitted to each other to enable free rotation.

[0004]

In such a conventional box-shaped storage container, even if a rib for preventing lateral deviation or a convex bottom is provided on the bottom of the container body, it is not an effective countermeasure against lateral deviation. Therefore, it is unavoidable that the lower storage container is inclined at a steep angle and that the upper storage container is easily detached and collapsed due to careless contact with the upper storage container. ing.

Further, the handle for carrying the storage container is
Since the mounting hole is formed in the outer wall of the container body and the proximal end of the handle is mounted in the mounting hole, the mounting hole formed in the container body causes the strength of the container body to decrease. In addition, when the handle is not used, the handle itself hangs downward and does not look good. When released, the handle rotates and collides with the outer wall of the container body and makes an unpleasant sound,
There were many problems to be solved in practice, such as damage to the handle or the container body by repeating these steps.

In view of the present situation, the present invention is not limited to the stable stacking of storage containers having the same shape and the same size, but also a small storage container having the same shape and a different size on a large storage container. The present invention also provides a storage container having a novel structure that can be stably stacked by changing the vertical and horizontal directions.

[0007]

According to a first aspect of the stackable storage container with a handle of the present invention, an upper portion is opened, and a supporting ridge is formed on the entire inner periphery of the back surface periphery. A stackable storage container composed of a rectangular parallelepiped container body and a pair of U-shaped handles attached so as to surround an outer wall of each short side of the container body,
The container body has a flange formed all around the upper part of the outer wall, and the base ends of the pair of U-shaped handles are pivoted to the mounting parts formed on the outer wall on the long side above the flange. It is freely attached, and each handle is configured to be held horizontally by a short side and a long side flange continuous with the short side. The upper edge of each side wall on the long side has a predetermined interval at the upper edge. A plate-shaped engaging piece having a plurality of mating grooves is integrally formed, and an overhanging piece is integrally provided so as to form concave grooves that open downward along the longitudinal direction in the vicinity of the bottom surface portion, A rib that engages with the engaging groove formed on the upper edge of the engaging piece is formed on the short side of each groove.

A second invention of the stackable storage container with a handle of the present invention is the stackable storage container with a handle of the first invention, wherein each of the container main bodies is provided on the back side of the short side of the container main body. A plate-shaped overhanging piece that is opposed to the supporting projection formed over the entire circumference on the inner side of the rear edge of the plate is integrally attached to form a groove, and the groove is formed on the long side of the groove. Ribs that engage with the engaging grooves formed in the engaging pieces of the container body are formed.

In the present invention, the container main body of the storage container having an open upper portion is formed by injection molding of thermoplastic synthetic resin. The storage container of the second invention is the same as the storage container of the first invention. The length of the side wall on the short side is approximately the same as the length of the side wall, and the side wall having a length slightly shorter than about 1/2 of the side wall on the long side is the short side. The storage containers can be stacked in a state of being orthogonal to the large storage container.

Further, the height of the side wall of the small-sized storage container is made higher to form a medium-sized storage container having a large storage capacity, and the medium-sized storage container is stacked on the large-sized storage container in an orthogonal state. , It is also possible to stack a small storage container on a medium-sized storage container in the same direction, or to stack a small-sized storage container at the same time as a medium-sized storage container in a state of being orthogonal to a large-sized storage container. You can also

On the other hand, the handles attached to these storage containers are
It has a U-shape as a whole, and has mounting holes formed at opposing base ends, respectively, and the mounting holes are projected to the side wall of the container body to engage with the outer periphery of the cylindrical boss, By forcibly press-fitting a rivet having a head on the handle, the handle can be rotated around the boss as a fulcrum, and the handle of the rivet prevents the handle from separating from the boss.

In the rivet to be used, a plurality of ring-shaped protrusions having a mountain-shaped cross section are provided at a predetermined interval on the outer periphery of the shaft portion to be engaged with the boss, so that the protrusions are forcedly pressed. It can bite into the inner peripheral surface of the boss to further strengthen the engagement between the two.

Further, by forming protrusions on the inside of the base end of the handle and forming a locking member for engaging with the protrusion on the side wall side, the handle tilted on the flange is fixed and The handle rotated upward can be prevented from falling on the flange.

[0014]

The stackable accommodating container of the present invention is specifically for accommodating and storing CDs, cassette tapes for audio and video, or office papers of a predetermined size. The handles that make up the main body can be fixed on the flanges formed on the side walls when not in use, and between storage containers of the same shape and size,
The engaging piece of the stackable storage container engages with the groove formed in the bottom of the stacking storage container, and the rib provided in the groove in the engaged state engages with the engaging groove formed on the engaging piece. Together,
It is possible to completely prevent the falling off by preventing the positional displacement in the diagonal direction as well as in the vertical and horizontal directions.

On the other hand, the storage container according to the first aspect of the present invention has a large size,
According to the second aspect of the present invention, the long side wall of the container body is made to substantially match the short side wall length of the large-sized storage container, and the short side wall length is set to the long side wall length of the large storage container. By using a small-sized storage container having a side wall having a length slightly shorter than ½ of the length, it is possible to stack the small-sized storage container in a state of being orthogonal to the large-sized storage container.

At the same time, if the height of the side wall of the small-sized storage container is made higher to form a medium-sized storage container having a large storage capacity, the medium-sized storage container and the small-sized storage container are orthogonal to the large-sized storage container. It is also possible to stack them in parallel in the state where they are kept, or to stack small storage containers in the same direction on a medium-sized storage container that is stacked orthogonally to a large storage container.

On the other hand, the handle attached to the storage container has a cylindrical boss projecting from a part of the side wall where the handle is not attached.
Since the base ends of the handles formed in a U-shape on these bosses are forcibly engaged and both are integrally connected by a rivet having a head, the handles can be handled without changing the strength of the container body. Can be attached.

At this time, a plurality of ring-shaped projections having a mountain-shaped cross section are formed on the shaft portion of the rivet at a predetermined interval so that the rivet is forcibly engaged with the boss and the projections are formed. Can bite into the inner peripheral surface of the boss to further strengthen the bond between the two.

Further, projections are provided inside the base ends of the handles facing each other, and locking members that engage with the projections are held on the outer peripheral surface of the side wall of the container body while the handles are held on the flanges. By providing the handle, it is possible to securely fix the handle which is tilted on the flange because it is not used, and the handle rotated upward during use does not fall on the flange even if the hand is released.

FIGS. 1 and 2 show a first embodiment of a storage container according to the present invention. The storage container 1 is basically a synthetic resin container main body 2 and a container main body 2. It is composed of a pair of synthetic resin handles 6 and 6 which are movably attached.

The container main body 2 has four peripheral walls composed of a pair of opposed side walls 3 and 3 forming long sides and a pair of opposed side walls 4 and 4 forming short sides, and a lower opening of the four peripheral walls. The bottom plate 5 is a generally rectangular parallelepiped having an open upper part, and a support ridge 7 is formed on the back surface of the bottom plate 5 inward of the peripheral edge over the entire circumference. The container body 2 is supported on a flat surface.

A narrow edge portion 8 is formed over the entire circumference on the outer peripheral portion of the opening edge of the container body 2, and the side walls 3 and 3 on the long side are extended upward to form plate-like engagement pieces 9. 9 are integrally formed, and four engaging grooves 10, 10, ... Are formed along the upper edges of the engaging pieces 9, 9.

In the engaging groove 10, the engaging groove 10 formed on each short side is basically located when the accommodating containers of the same shape and size are stacked and used. The engaging groove formed in the center is for locking so as not to shift, and the storage container 21A, which is smaller than the container body 2,
21B, which is used for locking 21B, and the engaging groove 10 on the short side and the engaging groove 10 provided at a predetermined distance from the engaging groove 10 at the center are basically It is a pair.

Further, the container body 2 has a flange 11 formed at the same height over the entire peripheral wall at the upper portion of the outer wall, and at the lower portion thereof, is opened downward between the side wall 3 and the longitudinal direction. Overhanging pieces 12, 1 forming the grooves 13, 13.
2 are integrally formed, and the groove 13 has a minimum width required to engage the engagement piece 9 on the long side of the container body 2, and the groove 13 has a short width. The engagement piece 9 is provided on the side.
The ribs 14, 14, ... That engage with the engaging groove 10 located on the short side formed in FIG.

On the other hand, the handle 6 attached to the container body 2
6 has a substantially U-shape as a whole, and mounting holes are formed in the opposing base ends, respectively, so that the mounting holes are formed on the long side of the container body 2 as shown in FIG. The rivet 1 is inserted into the boss 17 by engaging with the outer peripheral portion of a cylindrical boss 17 which is integrally projected on the side walls 3 and 3 above the flange 11.
When the 8 is forcibly mounted, the head 6 formed on the rivet 18 is prevented from coming off the boss 17, so that the handle 6 is rotatably attached to the container body 2.

At this time, when the boss 17 is made of polyethylene, it is preferable to use a hard material such as ABS resin for the rivet 18 and the rivet 18 has a hard material. If a plurality of ring-shaped projections 19 each having a mountain-shaped cross section are formed at a predetermined interval, when the rivets 18 are forcibly engaged with the bosses 17, the projections 19 are formed inside the bosses 17. Grip on the surrounding wall 6
Can be attached so as to be rotatable and non-removable.

Thus, the handle 6 rotatably attached to the container body 2 has a flange 11 on the short side and a long side continuous with the flange 11 when the handle 6 is not used, as shown in FIG. Since a part of the flange 11 is held horizontally with respect to the bottom plate 5, the container body 1 can be lifted by gripping the grip 6 and lifting it upward during use.

At this time, the protrusions 15 are formed inside the base end portions of the handles 6 and 6, respectively, and the protrusions 15 engage with the protrusions 15 while the handles 6 are held on the flanges 11 on the outer peripheral surfaces of the side walls 3 and 3. By providing the engaging member 16 to be fitted, the handle 6 can be fixed and held on the flange 11. When using the handle 6, if the handle 6 is rotated upward, the engagement between the projection 15 and the locking member 16 is easily released. Even if the handle 6 is released during use, the handle 6 will be Since the protrusion 15 engages with the engaging member 16, the protrusion 15 does not fall on the flange 11 and the lifting operation becomes easy again.

When the storage container 1 having such a configuration is to be stacked on the opening of another storage container having the same shape and size, the handles 6 are fixed on the flange 11 by tilting them as shown in FIG. When the handle is tilted down and vertically lowered onto another storage container which is also fixed in this state, the supporting ridges 7 formed on the back surface of the bottom plate 5 enter the inside of the side wall of the container body forming the other storage container, and at the same time, Overhanging piece 12, side wall 3 and long side support projection 7
The mating engagement pieces enter into the recessed grooves 13 formed between the ribs and the ribs 14 provided on the short sides, and engage with the inside of the engagement grooves located on the short sides of the engagement pieces. Accordingly, the storage container 1 can be securely fixed on the other storage container so as not to be displaced.

Incidentally, when accommodating containers of the same shape and the same size are stacked on each other, the two central engaging grooves formed in the engaging pieces of the other container body are not used at all, and they can be separated from each other. Can be disengaged from each other by simply lifting the upper container. Further, by engaging the rib formed on the other accommodating container to be stacked with the one of the recessed grooves formed on the engaging piece of the one accommodating container, the rib of FIG. It is also possible to stack the upper storage containers by shifting the position as shown by the dotted line.

Next, the storage container 2 shown in FIG. 3 and FIG.
1 is that the basic structure of the container main body 22 is the same as the structure of the container main body 2 described above, and the size thereof is smaller than that of the container main body 1, and only the structure described below is different.

That is, in the container body 22 constituting the storage container 21, the lengths of the long side walls 23, 23 are set to the length of the short side wall 4 of the storage container 1, and the short side walls 24,
The length of 24 is about 1 of the length of the side wall 3 on the long side of the storage container 1.
A length slightly shorter than / 2, and a flange 31 formed over the entire outer periphery of the side walls 23 and 24, and a support protrusion 27 formed inside the peripheral edge of the back surface of the bottom plate 5, An edge portion 28 surrounding the opening portion, and a locking piece 29 having a plate shape integrally formed on the upper ends of the side walls 23, 23 on the long side and having a plurality of engagement grooves 30 formed on the upper edge portion. , A protruding piece 32 for forming a concave groove 33 provided below the side wall 23 on the long side, a rib 34 provided on the short side of the concave groove 33, and a container body 22 It is the same as the structure of the storage container 1 in that it has handles 26 and 26 that can be freely attached, and that this handle 26 is fixed on the flange 31 when it is not used.

However, the structural difference between the two is that the bottom plate 2 on the short side of the container body 22 that constitutes the small-sized storage container 21.
5 extends along the peripheral edge of the rear surface of the plate-shaped support protrusion 27 on the short side of the plate at a predetermined interval and extends between the protrusion 39 and the support protrusion 27. Groove 4 opening downwards
0 and 40 are formed, and ribs 41 are attached to the long sides of the grooves 40, respectively.

In FIGS. 3 and 4, 36 is a handle 26.
Shows a protrusion for fixing the handle 26 on the flange 31 and not contacting the flange 31 even if the hand is released during use. Reference numeral 38 indicates the handle 26 so as to be rotatable and detached from the long side wall 23. It shows a rivet for disabling mounting.

The storage container 21 smaller in size than the storage container 1 in the above-described embodiment having such a configuration is completely different from the storage container 1 in the first embodiment when stacking storage containers of the same shape and size. They are the same, and they never change.

Then, the small storage container 21 is
Let B be a medium-sized storage container 21A in which only the height of the side wall is made higher to increase the storage amount, and the storage container 1 and these storage containers 21A and 21B are shown in FIGS. 8 and 9 below. Explain by quoting.

When the small-sized storage container 21B and the medium-sized storage container 21A are stacked on the large-sized storage container 1 at the same time, the length of each of the storage containers 21A and 21B is long along the short side direction of the large-sized storage container 1. With the side positioned,
When each of the storage containers 21A and 21B is lowered, the length of the storage container 1 becomes longer in the concave groove 40 formed between the overhanging piece 39 formed on the short side of each of the storage containers 21A and 21B and the support ridge 27. At the same time when the engaging piece 9 formed integrally enters the upper end of the side wall 3 on the side, the rib 4 formed on the long side of the concave groove 40 at the same time.
Engagement grooves 1 formed in the engagement piece 9 by reference numerals 1 and 41, respectively.
Since they are respectively engaged with the storage containers 0 and 10, two storage containers 21A and 21B of different sizes can be reliably stacked on the storage container 1 at the same time without displacement.

[0039]

In each of the stackable storage containers with a handle of the present invention, a handle is formed on the upper side wall of the container body so as to surround the peripheral wall to form a flange, and to carry the container body above the flange. Since the base end part of the is rotatably mounted, it can be held horizontally on the flange when the handle is not used, which requires troublesome work such as changing the position of the handle when stacking the storage containers. Can be stacked without.

Further, when accommodating containers having the same shape and the same size, the accommodating containers of the other accommodating containers are accommodated in the concave groove formed by the side wall formed on the bottom side of the container body and the projecting piece. At the same time as the engaging piece enters, the rib formed in the groove engages with the engaging groove formed in the engaging piece, so that the stacked storage containers are displaced in the vertical and horizontal directions, and further in the diagonal direction. It can be securely fixed without any occurrence.

The handle is rotated by engaging a mounting hole formed at the base end with a cylindrical boss provided on the container body and forcibly engaging a rivet having a head with the boss. Since it is mounted so that it can be removed and cannot be removed, the storage container can be manufactured without impairing the strength of the container body.

On the other hand, the stackable accommodating container with a handle of the second invention is such that the long side is approximately the same length as the short side wall of the stackable accommodating container with a handle of the first invention, and the short side. About half the length of the long side wall of the storage container of the first invention.
By forming the storage containers in different sizes and having different sizes, the small storage containers can be stacked in a state of being orthogonal to the large storage containers.

Further, if only the height of the side wall of this small storage container is changed to form a medium-sized storage container having a larger storage capacity, multi-sided stacking can be performed by combining three types of storage containers. You can

When mounting the handle on the container body,
If ring-shaped protrusions having a mountain-shaped cross section are formed on the outer periphery of the shaft portion of the rivet at a predetermined interval, the protrusions will be the inner peripheral wall of the boss when the rivet is pressed into the boss. It is possible to make the bond between them stronger.

Further, projections are provided inside the base ends of the grips facing each other, and locking members that engage with the projections are projected on the outer peripheral surface of the side wall of the container body while the grips are held on the flanges. By setting it, when the unused handle is laid down on the flange, the handle can be securely fixed in the horizontal state on the flange, and the handle lifted during use does not fall on the flange even if you release it.
It has a great practical advantage such that handling of the storage container is extremely convenient.
