Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container used for transporting foods or the like or displaying the same.

[0002]

Conventionally, when transporting or displaying food, a plastic container obtained by integral molding has been used. However, these containers are disposable, so costs,
In particular, it is manufactured with reduced raw material costs. That is, the thickness of the container is very small. For this reason,
The rigidity of the container side wall is insufficient, and the container is deformed during handling. Then, disordered arrangement of the ordered food products occurs, and the commercial value is greatly reduced.

In recent years, a container has been developed in which a frame serving as a container side wall is made of cardboard and a plastic bottom plate is adhered or heat-sealed to the frame. In the container having such a structure, since the container side wall has sufficient rigidity, the above-described problem does not occur. Here, for reference, a plastic plate is basically used as the bottom plate. This is because it is necessary to provide the bottom plate with projections and depressions serving as partitions, and it is most advantageous in terms of cost to provide the projections and depressions integrally with the bottom plate. Therefore, the bottom plate is made of plastic that can be integrally molded.

In recent years, the problem of garbage has become more serious, and the separation and collection and recycling of garbage have been actively promoted. As for the containers used for transporting and displaying the above-mentioned foods, the amount of circulation is enormous, so that it is naturally strongly desired to sort and collect / recycle them. However, the container has a frame portion forming a side wall made of a combustible paper material, and a bottom plate made of a non-combustible plastic material. Therefore, when disposing as waste (separate collection), it is necessary to completely separate the frame and the bottom plate. However, they cannot be easily separated because they are firmly joined by bonding or heat fusion. In addition, even if the separation is carried out with difficulty, the surface layer of the cardboard constituting the frame is peeled off and remains on the edge of the bottom plate, so that it is difficult to completely separate the cardboard.

Therefore, an object of the present invention is to provide a container which can easily and completely separate a bottom plate and a frame.

[0006]

An object of the present invention is to provide a container comprising a bottom plate and a frame provided as a container side wall so as to surround the bottom plate, wherein the bottom plate is made of plastic. And, the frame is made of wood, and a groove is formed in the inner peripheral surface of the frame along the circumferential direction, and the bottom plate has an edge formed in the groove of the frame. Is solved by a container characterized by being attached to the frame body.

That is, in the present invention, as described above, the frame is made of wood that can be cut, and a groove is formed in the inner peripheral surface of the frame along the circumferential direction. The bottom plate is attached to the frame by positioning the edge in the groove. That is, in the present invention, the joining between the frame and the bottom plate does not use bonding or heat fusion, which is very difficult to separate later. Therefore, when the container is discarded as garbage (separated collection), the flammable frame and the incombustible bottom plate can be easily and completely separated.

In the container of the present invention, in order to obtain a more secure mounting state of the bottom plate, the groove formed in the frame is formed in a continuous annular shape. Preferably, it is located in the groove. Further, in order to improve the workability when assembling the bottom plate to the frame, it is preferable that the width of the groove formed in the frame is larger than the thickness of the edge of the bottom plate (for example, about several times). In addition, by adopting such a structure, appropriate air permeability can be secured between the bottom plate and the frame. Therefore, when moisture or the like is trapped, the structure is suitable for storing an uncomfortable article.

Further, as the frame, a frame formed by deforming (for example, bending) a long plate-like material and joining one end and the other end thereof can be used. Note that the “bottom plate” in this specification does not mean only a flat plate. For example, a dish having a dish-shaped cross section having a large depression also corresponds to the bottom plate.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A container described below as an embodiment of the present invention comprises a bottom plate and a frame provided as a side wall of the container so as to surround the bottom plate.
The bottom plate is made of plastic, and the frame is made of wood, and a groove is formed in the inner peripheral surface along the circumferential direction, and the bottom plate has an edge portion of the frame. It is attached to the frame by being located in the groove. In particular, in the present embodiment, the groove formed in the frame body is a continuous annular shape, and the edge of the bottom plate is positioned (free-fit) in the groove over the entire periphery. Further, in the present embodiment, the width of the groove formed in the frame is made larger than the thickness of the edge of the bottom plate. Further, as the frame body, one formed by bending a flat long material and joining one end and the other end thereof is used.

Next, an embodiment of the present invention will be described in more detail with reference to FIGS. FIG. 1 is an external view of the container according to the present embodiment before the lid is attached, and FIG. 2 is a perspective view showing a state in which the container according to the present embodiment is separated into a bottom plate and a frame. 3 is a sectional view taken along line XX in FIG. The container according to the present embodiment indicated by A in FIG. 1 (hereinafter, referred to as the present container) is used, for example, when transporting food or the like or displaying it. Actually, after the food etc. are stored, the container A
Is attached. Then, the lid B is fixed to the main container A with an adhesive tape or the like, so that it can be transported or displayed. Note that the lid B is made of plastic, like the bottom plate (which will be described later in detail) constituting the container A.

The container A comprises a bottom plate 1 and a frame 2. Among them, foods and the like are placed on the bottom plate 1. Therefore, in the present embodiment, a dish-shaped section having a large depression is used as the bottom plate 1. On the bottom surface of the bottom plate 1, a large number of cross-shaped protrusions 1a are integrally formed. The protruding portions 1a are for preventing displacement of the placed food or the like, in other words, for maintaining the initial orderly arrangement.

The bottom plate 1 is provided with an annular rib 1b for reinforcement so as to surround the depression. However, the annular rib 1b is also integrally formed with the bottom surface portion, similarly to the convex portion 1a. Furthermore, in the bottom plate 1,
As shown in FIG. 2, an annular edge 1c is provided to surround the annular rib 1b. The edge 1c extends horizontally from the lower end of the annular rib 1b, and has the same thickness as the other portions.

The bottom plate 1 is obtained by integrally molding a plastic such as polyethylene, as can be seen from the fact that the projections 1a and the annular ribs 1b are integrally formed therewith. On the other hand, the frame 2 serves as a container side wall, and is provided so as to surround the bottom plate 1.

The frame 2 is made of wood that can be cut, for example, Chinese wood. A groove 2a is formed on the inner peripheral surface along the circumferential direction, and this groove 2a is used for joining with the bottom plate 1 as described later in detail. Although only a part of the groove 2 a is shown in FIG. 2, the groove 2 a is actually formed in all directions on the inner peripheral surface of the frame 2. That is, the groove 2a is a continuous annular one.

Further, in the present embodiment, the frame 2 is formed of a single flat long material. More specifically,
A wedge-shaped notch is provided at three places of the long material, and the long material is bent at the position of the notch. The frame 2 is formed by joining (eg, bonding) one end and the other end of the bent long material. However, the thickness of the long material is such that the frame 2 exhibits a predetermined rigidity. Needless to say, the frame 2 is not limited to one manufactured by such a method.

[0017] Incidentally, (in FIG. 3, indicated by T ₁₎ the width of the groove 2a formed on the frame 2, (in Fig. 3, indicated by T ₂₎ the thickness of the edge 1c of the bottom plate 1 larger than Has become. Specifically, the former is about three to five times as large as the latter. Now, the container A is composed of the bottom plate 1 and the frame 2 as described above, and the bottom plate 1 has its edge 1c positioned (freely fitted) in the groove 2a of the frame 2 as shown in FIG. By this, the frame 2
Attached to. In particular, since both the edge 1c and the groove 2a are annular, the edge 1c is located in the groove 2a over the entire circumference. Therefore, the bottom plate 1 is securely fixed to the frame 2 and does not fall off during transportation or handling.
On the other hand, because of such a structure, in the present embodiment, the bottom plate 1
No bonding or heat fusion is used to join the frame and the frame body 2, which is very difficult to separate them later. Therefore, this container A
When waste is discarded as waste (separated collection), the incombustible bottom plate 1 and the combustible material frame 2 can be easily and completely separated. Specifically, it is only necessary to deform the bottom plate 1 by pressing or the like, and remove the edge 1c from the groove 2a.

The container A exhibits the following effects. That is, since the edge 1c of the bottom plate 1 is not fixed to the frame 2 by adhesion or heat fusion, a small gap exists between the two. That is, edge 1
Air permeability is ensured between c and the groove 2a. Therefore,
Due to a synergistic effect with the fact that the frame 2 is made of wood, it is possible to store an article having a bad condition when moisture or the like is trapped without any problem.

In this embodiment, a case where a rectangular (mouth-shaped) frame is adopted as the frame has been described as an example. However, the frame constituting the container of the present invention is, of course, not limited to such a form. In addition to the rectangular shape, the frame body may be formed into a triangular shape or a polygonal shape such as a pentagon or more. Alternatively, the shape may have no corner, for example, a circular shape.

[0020]

According to the present invention, the bottom plate and the frame constituting the container can be easily and completely separated.
