Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a unit container in which fish and shellfish are boiled in an appropriate amount and can be separated for each segment.

[0002]

2. Description of the Related Art Generally, seafood such as firefly squid, squid, coconut, and pearl oyster is boiled and placed on a distribution route. Conventionally, the seafood was put in a wooden box of about 30 cm square, and the seafood was boiled by stacking it in multiple layers and immersing it in boiling water. At present, plastic containers such as polypropylene are widely used in place of wooden boxes, but the processing method and the structure of the container itself are almost unchanged.

[0003]

However, one problem after boiling a large amount of seafood is that it must be subdivided into appropriate amounts. This is a cause that it takes a lot of time to divide it into small pieces and the shape of the rice cake is lost after it is boiled.

In order to improve this point, a plastic container divided into a plurality of parts is used. For example, as shown in FIG. 9, one container is integrally molded in a state of being divided into six, and seafood is put in this container and stacked in multiple stages for boiling. Then, after that, it is divided into small parts by cutting each section with a knife or the like. However, this container has the advantage that it does not have to be transferred to another container and does not lose its shape, but it needs to be separated using a tool such as a knife, it can not be cut straight and it becomes uneven, and the cut surface is It has drawbacks such as being sharp and dangerous and making it difficult to wrap a wrap film or the like.

[0005]

Therefore, the present inventor has accomplished the present invention as a result of intensive research in view of the above problems, and is characterized by connecting a plurality of parallel states. A unit container for storing the seafood in small portions by boiling the seafood in an appropriate amount and separating each of the divisions, and is a tray container formed in a rectangular shape in plan view. In the upper portion of the peripheral surface, an upper opening groove is formed on one side and a lower opening groove is formed on a side opposite to the one side, and an outer rising portion of the upper opening is formed. Of the outer hanging portion of the lower opening groove by providing a hooking portion on at least one surface of the front and back surfaces and the surface of the inner rising portion facing the outer rising portion. The back surface and the surface of the inner hanging part facing the outer hanging part In that the engaging section is provided on one surface at least one.

As used herein, the term "tray body" refers to a container in which a rectangular bottom surface is surrounded by a standing surface. Since this is to be used when boiling seafood, at least the bottom surface has a colander or a large number of holes to drain water. The basic shape of the tray body is not limited to a simple container shape, and may be any shape such as a flange portion provided on the upper end of the peripheral surface. The size is not limited and is generally 50 × 10.
It is within the range of 0 mm to 200 × 400 mm. Further, the thickness and the material may be any as long as they meet the purpose of the present invention.

The "upper opening groove" is provided in an upper portion of the peripheral surface located on one side of the tray body, and is formed by an outer rising portion and an inner rising portion which are arranged side by side in opposition to each other. A groove whose upper part is opened. The outer rising portion and the inner rising portion are integrally formed with the tray body. Normally, when an inverted L-shaped flange is provided on the upper part of the peripheral surface of the tray body or on the peripheral edge of the upper end of the peripheral surface, the hanging part of the flange has a structure which also uses the inner rising part. .
In other words, the part slightly below the upper edge of the peripheral surface of the tray body,
Alternatively, the upper opening groove is formed by providing an L-shaped one that forms the outer rising portion and the bottom surface of the groove at the lower end of the hanging portion of the inverted L-shaped collar portion. Of course, the upper portion of the peripheral surface of the tray main body may be the outer rising portion, and the L-shaped one that forms the inner rising portion and the bottom surface of the groove may be provided inside the outer rising portion. Further, the upper opening groove may be provided on two adjacent side portions of the tray body. That is, in the case where the trays are simply connected in a line in the horizontal direction, they may be provided on only one side of the tray main body, but if they are provided on two adjacent side parts, the trays are connected not only in the horizontal direction but also in the vertical direction. This is because it can be done.

The "lower opening groove" is provided in the upper portion of the peripheral surface of the side portion of the tray main body at a position facing (facing) the side portion where the upper opening groove of the tray body is provided, and is in a state of facing each other. A groove formed by the outer hanging part and the inner hanging part that are juxtaposed in parallel with each other. The outer hanging part and the inner hanging part are integrally molded with the tray body. Usually, the upper part of the peripheral surface of the tray body is structured to use the inner hanging part together. That is, the lower opening groove is formed by providing the tray body with the inverted L-shape forming the outer hanging portion and the top surface of the groove at the upper end portion of the peripheral surface of the tray body. Since the lower opening groove formed in this manner generally has the same structure as an inverted L-shaped flange portion provided in a container, in a container having such a flange portion, The groove formed between the container body and the container body may be used as it is as the lower opening groove. Therefore, in this case, the lower opening groove is formed over the entire circumference of the tray body,
As described above, the upper opening groove may be formed outside the lower opening groove. When the upper opening groove is provided on the two adjacent side portions, the lower opening groove is also provided on the other two adjacent side portions so that the upper opening groove can be connected in the horizontal direction and the vertical direction.

Outer hanging portions and outer rising portions of other trays arranged on both sides of the tray are fitted into the upper opening groove and the lower opening groove of the tray. Regarding the width of each groove, the width may be such that both the outer hanging portion and the outer rising portion fit in close contact with each other, but it is preferable to widen one of them in order to facilitate connection. .

The "hooking portion" is a protrusion, a ridge or a groove provided on at least one of the front and back surfaces of the outer rising portion of the upper opening groove and the surface of the inner rising portion facing the outer rising portion. It means something that gets caught.

The "engagement portion" is a projection, a ridge or a protrusion provided on at least one of the front and back surfaces of the outer hanging portion of the lower opening groove and the surface of the inner hanging portion facing the outer hanging portion. It refers to something that is hooked to a catch such as a groove.
The relationship between the hooked portion and the hooked portion is such that, when one is a protrusion or a ridge, the other is a protrusion or a ridge, or a groove or a hole, and these are engaged with each other. Good.

The height and depth of the projections of the above-mentioned hooking portion and hooked portion are about 0.02 to 3.0 mm, preferably 0.1 to 0.5 mm, but the outside hanging The thickness and elasticity of the portion and the upper opening groove, or the outer rising portion and the lower opening groove can be arbitrarily set and are not particularly limited.

The tray 1 has a bottom 11 of the tray main body 2 in the shape of a hollow and a plurality of holes 12 provided in the peripheral surface 3 for accommodating small fish such as locusts. The tray in this example has a size of about 200 × 100 mm, a depth of about 26 mm, and a thickness of about 1 mm. Further, when the trays 1 are stacked, receiving portions 18 are provided at the four corners in order to secure a volume for the contents, that is, to prevent the bottom portion of the upper container from reaching the bottom portion of the lower container. There is.

When the tray 1 is used as shown in FIG. 2, the outer hanging parts 9 of the other trays 1 adjacent to the upper opening groove 4 of the tray 1 are fitted and the ridges 8 are engaged with each other. The trays 9 are connected and the nine trays 1 are made into one divided collecting container 13. Of course, when connecting in only one direction without connecting in both vertical and horizontal directions as in this example, the upper opening groove 4 is provided on one side and the lower opening is formed on the side facing the one side. Only the groove 5 may be provided. Fish and shellfish such as locusts are put into the collecting container 13 almost evenly for each of the sections formed by the tray 1, and a plurality of the stacked pieces are immersed in boiling water and boiled. Then, after being boiled, it is transported in this state and separated into individual trays 1 for sale.

FIG. 3 shows how the trays 1 are connected to each other.
At the same time that one outer hanging portion 9 fits into the other upper opening groove 4, the ridge 8 provided on the inner rising portion 7 and the ridge 8 provided on the outer hanging portion 9 cross over each other's top portion. It will be hooked and connected in the closed state. Tray body 2
The ridges 8 of the upper opening groove 4 portion provided on the longer side portion of the ridge are divided into three as shown in FIG. 1, and the ridges 8 of the lower opening groove 5 portion engaging with this are also provided. Similarly, it is divided into three parts. This is for facilitating separation of the connected trays 1. However, it is particularly limited because it is greatly affected by the degree of fitting between the outer hanging portion 9 and the upper opening groove 4, the height and shape of the ridge 8. Not something to do.

Another example of the combination of the hooked portion and the hooked portion is shown in FIGS. 4 (a) and 4 (b). The figure (a) is a ridge 8 and a groove 1.
