fish container

【Technical field】

TECHNICAL FIELD The present invention relates to a container, particularly a foldable plastic container, which is used as a packing box or storage box for fresh fish, fruits and vegetables, and general foodstuffs, for example.

[Background technology]

For example, when fresh fish is transported or stored in a freezer warehouse, a container (fish box) called a toro box with an open top is used. As such a container, conventionally, there are a container made of styrene foam, a wooden container made of a plurality of plates, and the like.

In particular, the former is made by molding a polystyrene foam into a rectangular parallelepiped shape as described above, and is used in large quantities today because it is lightweight and can be easily manufactured. However, this Styrofoam container becomes fragile when rapidly cooled, so it is not suitable for storing fresh fish in a freezer warehouse.

On the other hand, the latter wooden container does not have this problem, but it is more troublesome to manufacture than the former, and it is customary to dispose of it once used. It cannot be denied that there is an aspect of wastefully consuming precious wood resources. Thus, the conventionally used styrene foam containers and wooden containers each have their advantages and disadvantages. Even in the field, there was a problem in disposing of used containers because they were often disposed of only once. In this case, a wooden container can be burned, but a styrofoam container tends to generate toxic gases when burned, and it is also a cause of environmental pollution because it does not easily decompose under natural conditions.

In addition, in the above-mentioned conventional containers, even if they can be used repeatedly, the structure is such that each side plate is fixed vertically to the bottom plate of the container. Therefore, for example, empty containers (empty boxes) need to be collected.

The present invention addresses these problems by providing a product that can be used repeatedly and that is easily folded and assembled to reduce bulk when stacked in an empty state. The primary objective is to provide a collapsible plastic fish container which is of a robust construction when assembled. Also, in this case, when the side plates of the container are erected, the side plates are to be easily positioned in a predetermined upright position with respect to the bottom plate and to be securely held in the upright position. [Disclosure of the Invention]

To achieve the above object, a container for fish or the like according to the present invention is made of plastic and has a rectangular bottom plate in a plan view that forms a bottom surface, and a side edge portion of the bottom plate that is rotatably connected to the bottom plate. a pair of retractable first side plates forming side surfaces facing each other, and a pair of retractable first side plates also rotatably connected to the bottom plate and forming side surfaces perpendicular to the first side plates. and a second side plate, wherein the first side plate and the second side plate can be folded in this order.

When a rectangular bottom plate is used in the above container, the first collapsible side plate is attached to both longitudinal edges, and the second collapsible side plate is attached to both lateral edges. It is desirable that the second side plate of which is provided with a string attachment hole to which a string can be attached for convenient transportation. Also, in that case, in order to prevent the second side plates from falling inward, the second side plates are arranged so that the longitudinal end surfaces of the first side plates face the inner surfaces of both ends of the second side plates in the upright state. It is preferable that both ends of the second side plate are received by the end faces of the first side plate by placing the first side plate therebetween.

By the way, in a container like the one described above whose sides are made up of foldable side plates, when the side rails folded inward are raised, the side plates are not only easily positioned in an upright position. It must be held securely so that it does not topple over in that position. Therefore, in order to achieve this, the peripheral edge of the bottom plate is provided so as to abut against the outer surface of each side plate when the side plate is erected. On the other hand, the longitudinal end of the second side plate or its vicinity is engaged with the longitudinal end of the first side plate when the first side plate is upright. and provide an engaging portion for holding the first side support in an upright position.

In addition, as a positioning means between the upper and lower containers when stacking multiple layers of this kind of container, the bottom surface of the bottom plate has

, the first guide ribs are formed at the four corners to fit inside the raised portions of a similar container for fish, etc. when each side plate is folded and stacked on another similar container for fish, etc.; A second guide rib is formed at a position more inward than the first guide rib. is desirable.

According to the above configuration, when the fish container is not used, the first side plate and the second side plate are folded in this order, so that the size of the container in the depth direction (height direction) is compact. Since it is converted into a solid, the volume is reduced accordingly. Therefore, even when transporting or storing a large number of containers of the same type in a stacked state, the overall volume is much smaller than that of conventional containers.

In addition, when the side plates are erected from the state in which the side plates are folded in this way to form the respective side surfaces, that is, when assembling the container, the second side plate is first erected, and then the first side plate is erected. Raise the side support. At this time, the above-mentioned standing plates are installed at or near the peripheral edge of the bottom plate and the longitudinal ends of the second side plate. By providing the rising portion and the engaging portion respectively, each side plate abuts against the rising portion in the upright position, and not only is the outward rotation prevented, but also the engaging portion The end portions of the first side plate are engaged to connect the second side plate to the side plate, thereby securely holding both side plates in their upright positions.

Furthermore, in this case, if the first side plate is between the second side plates in the upright state as described above, both ends of the second side plate are received by the end faces of the first side plate, so the second side plate does not fall inward. will be reliably prevented.

Therefore, according to the above configuration, when the first side plate is erected after the second side plate is erected, the end of the first side plate engages with the engaging portion of the second side plate, thereby automatically maintaining the upright state. The first and second side plates are securely connected and held in the upright position.

By the way, when the plane shape of the bottom plate, that is, the container is particularly rectangular, when it is carried by hand, both ends in the longitudinal direction (that is, the sides extending in the lateral direction) are Digging is customary. Therefore, if the second collapsible side plate that forms the side surface in the lateral direction is provided with a string attachment hole as described above, by attaching a string to this hole, for example, the above-mentioned It is convenient when transporting a container because the string can be grasped by hand or hooked to the tip of a so-called hand hook (a tool for hooking fish) ο

Furthermore, the first guide rib and the second guide rib as described above are formed on the lower surface side of the bottom plate of this container. As a result, when the containers are stacked with the side plates folded, the first guide rib of the upper container fits inside the raised portion of the lower container, while the side plates are raised. Since the second guide ribs are fitted inside the side plates of the lower container when the containers are stacked in a folded state, in either case, the upper and lower containers must be aligned with each other on the plane. Containers can be stacked in a stable state. [Brief description of the drawing]

[Best mode for carrying out the invention]

FIG. 1 is an overall perspective view of a fish container showing an embodiment of the present invention, FIG. 2 is a front view of the same, FIG. 3 is a side view of the same, and FIG. 4 is a plan view of the same. . As shown in these drawings, this fish container 1 is made of plastic and has a rectangular bottom plate having a large number of drain holes 2a 2a forming a bottom surface. 2, a pair of foldable first side plates 3, 3 forming both longitudinal side surfaces of the container 1, and string attachment holes 4a 4a for appropriately attaching strings. It is composed of a pair of collapsible second side plates 4, 4 that form both sides of the container 1 in the transverse direction. ·

As shown in FIG. 5, the bottom plate 2 is formed with rising portions 2b and 2c on the peripheral portion thereof.

The lower edges of the side plates 3, 3, 4, 4 are arranged along the inner sides of 2b, 2c. and those side plates 3,

Both side portions and central portions of the lower edges of 3, 4 and 4 are rotatably connected to the bottom plate 2 via respective hinge portions 5. As shown in FIG. In that case, all the hinge portions 5 except for the hinge portion 5 at the center of the lower edge of the second side plate 4 have, as shown in FIG. , Metal connecting pins 6 are used at the center of rotation (center of hinge), respectively. As shown in Fig. 3, a shaft portion 8, which serves as the center of the hinge, is integrally formed in advance on the side of the second side plate 4 instead of the connecting pin 6 as described above, Mi .

The shaft portion 8 is rotatably engaged with an engaging portion 9 formed on the bottom plate 2 side.

Here, a stepped portion 2d5 is formed at a predetermined height position inside the upright portion 2c that extends particularly in the transverse direction of the container 1, and the stepped portion 2d5 extends along the longitudinal direction of the container 1. 6, a support portion 10 for the connecting pin 6 constituting the hinge portion 5 is formed at the corner formed by the rising portion 2b and the bottom surface of the bottom plate 2. In the lateral direction of the antenna 1, as shown in FIG. 7, the engaging portion 9 is formed at the corner formed by the rising portion 2c and the stepped portion 2d. When the container 1 is in an empty state, first, the first side plates 3, 3 are laid down from the upright position shown in FIG. 1 to the inner bottom plate 2 side as shown in FIG. By similarly folding 4, 4 inward as shown in Fig. 8, each side plate 315, 3, 4, 4 can be folded inward, that is, toward the bottom plate 2, centering on the connecting pin 6. I'm getting used to it.

Furthermore, in this container 1, as shown in an enlarged view in FIG. 9, the longitudinal ends of the second side plates 4 or their vicinity are provided with the ends when the first side plates 3 are erected. There are provided a first engaging portion 11 and a second engaging portion 12, respectively, which engage 20 to hold each first side plate 3 in an upright position.

Of these, the first engagement portion 11 is formed by cutting out both ends of each second side plate 4 in concentric circular arc shapes centering on the connecting pin 6 (see FIG. 6) on the side of the second side plate 3. 11a is formed, and a substantially semi-cylindrical projection 11b is provided at the free end of the 25 notched piece 11a. Then, the second side plate 4 is erected When the first side plate 3 is erected in the folded state, the protrusions 11b of the cutout pieces 11a are formed on the outer surface side of both ends of each first side plate 3 so as to correspond to the protrusions 11b. By engaging with the recess 3a, the first side plate 3 is positioned in the upright position and connected and held.

Here, when the first side plate 3 is erected, the end portion of the first side plate 3 slides on the protrusion 11b of the cutout piece 11a, so that the cutout piece 11a is bent. The projection 11b side is pushed outward and temporarily elastically deformed, and when the first side plate 3 is rotated to the upright position, the projection 11b is deformed by the elasticity of the plastic material. is configured to engage with the recess 3a on the side of the first side plate 3. In this case, ribs are formed on the outer surface side of the cutout piece 11a so as to obtain an appropriate amount of elasticity (see, for example, Fig. 1).

On the other hand, the second engaging portion 12 has an L-shaped cross section. Also in this second engaging portion 12, when the first side plate 3 is erected with the second side plate 4 standing upright, the predetermined portion 3b at the longitudinal end of the first side plate 3 is By engaging with the engaging portion 12 and the outer surface side of the predetermined portion 3b abuts against the inner side of the second engaging portion 12, the first side plate 3 is further reliably positioned in the upright position. It is designed to hold

In addition, as shown in FIGS. 6, 7 and 10, on the lower surface side of the bottom plate 2, when this container 1 is folded and stacked on another similar container, there is a portion of the container. The first guide rib 13 (see Fig. 6) fitted inside the rising part ) are formed at the four corners, and second grooves fit inside each side plate of a similar container when each side plate 3, 3, 4, 4 is stacked on another similar container in an upright state. A guide rib 14 is formed at a position inward of the first guide rib 13 . A metal member 15 is inserted into each of the second guide ribs 13 in advance at the time of molding, so that when the container 1 is dragged, the ribs 1 The container 1 configured as described above can, when it is empty, be able to remove the first side plates 3, 3 and the second side plates 4 as needed. , 4 are folded. In that case, first, as shown in Figs. 5 and 9, each first side plate 3 is laid down on the bottom plate 2, and then each second side plate 4 is laid down inward as shown in Fig. 8-. 5 In this way, the state where both side plates 3, 3, 4, and 4 are folded

', the dimension in the depth direction (height direction) of the container 1 is made compact, so the volume is correspondingly reduced. Therefore, when storing or transporting a large number of containers 1 of this type, a smaller storage space 0 or transport space than before is sufficient.

On the other hand, when the side plates 3, 3, 4, 4 are to be erected after being folded in this way, the second side plates 4, 4 are first erected, almost opposite to the above case. After that, raise the first side plates 3, 3. At this time, the outward rotation of the first side plates 3, 3 and the fifth and second side supports 4, 4 causes the side plates 3, 3 and 4, 4 to abut against the rising portions 2b and 2c, respectively, in the upright position. vinegar The side plates 3, 3 and 4, 4 are prevented from falling outward.

In addition, cutout pieces provided at both ends of each second side plate 4

The end of each first side plate 3 slides against the projection 11b of 11a, and the projection 11b side of the notch piece 11a is pushed outward and temporarily elastically deformed. When the first side plate 3 is rotated to the upright position shown in FIG. 1, the elasticity of the plastic material pushes the projection 11b into the recess at the end of the first side plate.

3 Engage a. As a result, the first side plates 3, 3 are less likely to fall inward and are held in the upright position. 3 is located between the second side plates 4, 4 and both ends of the second side plates 4, 4 are received by the end faces of the first side plates 3, 3. This reliably prevents the second side plates 4 from falling inward.

Furthermore, when the concave portion 3a of the first side plate 3 is engaged with the convex portion 11b, that is, the first engaging portion 11 of the second side plate 4 as described above, the longitudinal end portion of the first side plate 3 is The predetermined portion 3b of the second side plate 4 is engaged with the second engaging portion 12, and the outer surface side of the predetermined portion 3b abuts the inner side of the second engaging portion 12. As a result, the first side plate 3 is more reliably positioned in the upright position, and the function of preventing the first side plate 3 from falling over due to the rising portion 2b of the bottom plate 2 ensures that the first side plate 3 falls outward. will be prevented. Therefore, in this container 1, the second side plates 4, 4 and the first side plates 3, 3 are successively erected, predetermined portions of the ends of the first side plates 3, 3 are engaged with the first engaging portions 11 and the second engaging portions 12 on the second sides 4, 4. It is positioned in the upright position by itself, and the first and second side plates 3, 3, 4, 4 are securely connected and held in the upright position.

In addition, string attachment holes 4a, 4a are provided in each of the second side plates 4 that form the lateral sides of the container 1, and strings are attached to the holes 4a, 4a. Thus, for example, the string can be grasped by hand or hooked to the tip of a so-called tegari (a tool for hooking fish) during transportation, which is convenient.

Further, on the lower surface side of the bottom plate 2 of the container 1, first guide ribs 13 13 and second guide ribs 14 14 are formed at predetermined positions. When a plurality of containers 1 are stacked with the side plates 3, 3, 4, 4 folded, the first guide ribs 13 of the upper container 1 are aligned with the rising portion 2 of the lower container 1. b, 2c, while the second guide rib 14 is positioned on the bottom side of the container 1 when the side supports 3, 3, 4, 4 are stacked in an upright state. Since the containers are fitted inside each side frame 3, 3, 4, 4, in any case, the upper and lower containers can be stacked in a state where the plane positions of the upper and lower containers are aligned, that is, in a stable state. .

In addition, when multiple containers are stacked as described above, the upper and lower parts are closed by other containers, resulting in a decrease in air permeability. A plurality of ventilation holes may be provided in the second side plates 3, 3 as required.

11 and 12 are an enlarged side view and a perspective view of a main part of a fish container 21 showing another embodiment of the present invention. As shown in these drawings, in this container 21, arcuate guide grooves 25 are formed at both ends of the second side plate 24 in the longitudinal direction. 1 Engagement pins 27 that engage with the guide grooves 25 are projected from both ends of the side plate 23 in the longitudinal direction. When the first side plate 23 is raised or lowered with the second side plate 24 raised, the engagement pins 27 are guided by the guide grooves 25. The rotation operation of the first side plate 23 can be performed smoothly.

13 and 14 are a perspective view and an enlarged longitudinal sectional view of a main part of a fish container 31 showing still another embodiment of the present invention. As shown in these drawings, in this container 31, a name sheet mounting portion 35 is formed on the outer surface of the first side plate 33. The name sheet mounting portion 35 has an insertion port 35a at one end in the longitudinal direction. It can be inserted from the insertion port 35a into the cover, and a protective sheet 37 made of a transparent plastic sheet or the like can be attached thereon. Here, as a method of displaying the company name, etc., it is possible to directly print the company name, etc. on the protection sheet 37 without using the name sheet 36. Of course.
