Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tray for packaging seafood and the like in units for sale to consumers.

[0002]

2. Description of the Related Art Seafood such as peeled shellfish was previously given to a retailer in a large wooden box or the like, where it was sold as a plate in a retail unit. However, with the diversification of retail formats such as supermarkets, producers are now demanding products that are subdivided into retail units and packaged. For this purpose, a polystyrene foam tray or the like is used, and heat shrink wrap packaging is used for this.

[0003]

However, when a large number of Styrofoam trays are piled up, the contents will be crushed. Therefore, it is necessary to have a means for packing a small amount in a sturdy box and transporting it, which causes a distribution cost. Become. Therefore, a container that allows the contents to be closely stacked in a packaged state is desired. Moreover, there is a demand for a container that is suitable for being displayed as a product in a store as it is, that is, a container that enhances the willingness to purchase. In particular, since seafood contains a large amount of water, it is preferable to use a container that can be drained without retaining the exuded water in the package.

[0004]

SUMMARY OF THE INVENTION The present invention is to solve the above problems and provides a quadrangular flat plate tray,
A contents storage section having a quadrilateral bottom and an open top surface;
The content storage part protruding from a thin frame part which is continuous around the upper side of the content part storage part and has a flat upper surface, and a lower surface of at least one pair of two facing sides of the frame part. The outer lower surface of the tray is formed with a hook portion having a protruding length equal to or longer than that of the outer lower surface of the tray, and the outer lower surface of the content storing section is provided with a protrusion that bites into and positions the content storing section of the tray stacked below. The tray is characterized in that one or more pairs of cuts are provided at positions where the outer periphery of the frame portion faces each other.

Further, in this case, one or more holes for draining water are provided on the side wall of the contents storage portion, characters or symbols are displayed on at least one side of the upper surface of the frame portion, and a notch is provided. It is also characterized in that a reinforcing rib for connecting with at least one of the outer surface of the contents storage portion and the hook portion is provided on the back surface of the frame portion of the portion.

[0006]

The tray of the present invention is in the shape of a quadrilateral flat plate, but is made by injection molding of polyethylene or the like. That is, it has a quadrilateral bottom, and generally has a shallow bottom and an open top. A thin frame portion having a flat upper surface is continuous around the upper edge of the box-shaped contents storage portion, that is, the edge. This frame part plays a role of a handle when holding the tray, and also holds a vertical interval when the trays are stacked by the hook part, which will be described later, and a force of supporting the force. Also, since the frame has a flat top surface, the manufacturer's name, trademark, etc. can be attached with an embossed pattern when the tray is molded. Of course, it may be printed directly or a separately printed paper may be attached.

Further, a hook portion having a protrusion length equal to or longer than the outer lower surface of the contents storage portion is provided on the lower surface of the frame portion. The hook portion is usually provided in parallel with the side of the contents storage section, and may be provided in parallel with at least one pair of the two pairs of sides. Therefore, it is possible to widen the width of the frame portion by only a pair of sides on the side where the producer's name and the like are written and to provide the hook portion on the back side thereof. The shape of the hook part is not particularly limited, and it is not limited to being parallel to the side of the content storage part described above, but may be zigzag, or a plurality of short sides perpendicular to the side may be provided.

When the trays are stacked, the hook portion comes into contact with the frame portions of the adjacent trays and plays a role of maintaining the vertical gap. Therefore, as described above, it is necessary to make the protruding length the same as the outer lower surface of the contents storage portion or more. When the protruding length is made longer than the outer lower surface of the contents storage section, even if the contents are raised and stored to some extent, they will not be crushed by the tray stacked on top.

When the trays constructed as described above are piled up for transportation or the like, a protrusion is provided on the outer lower surface of the contents storage portion so as to keep the position constant. As a result, this protrusion bites into the inside of the contents storage portion of the tray stacked on the lower side to prevent lateral displacement and to keep the stacking position constant. The protrusions may be, for example, rod-shaped protrusions at the four corners or L-shaped protrusions at the four corners. Furthermore, it is possible to provide a protrusion with an appropriate length at the center of each side of the contents storage section, or to provide the protrusion entirely over the entire length of each side.

When the protrusion length of the hook part is the same as the outer lower surface of the contents storage part, the protrusion part may be directly projected from the contents storage part, but when the protrusion length of the hook part is larger than this. Since it is necessary to further protrude, it may become long and easily broken. Therefore, it is possible to reinforce a part of the length integrally with the hook part or the extension part thereof. The length of protrusion of the protrusion from the contents storage portion or the hook portion needs to be lengthened accordingly when the edge of the contents storage portion is particularly gentle, but usually 3 to 4 mm is sufficient. . In addition, when the tray is placed as a stand-alone display for display, it will play the role of a foot, so the same protrusion length is required for each part.

Further, one or more pairs of cuts are provided at the opposite positions of the outer periphery of the frame portion. If the cords are tied and bound in this portion in a state where the trays are stacked, the cords will not be displaced laterally. Furthermore, by specifying the position where the cord is to be hung in this way, it is possible to provide reinforcement ribs that are connected to at least one of the outer surface of the contents storage part and the hook part on the back side of the frame part of this part for intensive reinforcement. it can. As a result, the frame portion can be prevented from bending even when the string is strongly applied. The reinforcing ribs may have the same height as the hook portion and may support the vertical force of the stacked trays in the same manner as the hook portion. Only the reinforcement for the binding force may be used, and which one should be decided depending on the situation such as the size of the tray. It should be noted that this notch may be provided on at least one pair of the two opposing sides of the frame portion.
Of course, a plurality of pairs may be provided on the sides of the pair.

Further, when a marine product such as shellfish is stored as the content, it is preferable to provide a draining hole at one or more locations on the side wall of the storage section for the content. The position of the hole may be, for example, a square hole whose one side matches the bottom surface of the contents storage section,
The size should be an appropriate size so that the contents do not fall out.

FIG. 1 is a perspective view showing an embodiment of the tray of the present invention, which is made of polyethylene, and the approximate dimensions are 100 mm in width, 170 mm in length, and 1 in height of the contents storage section 1.
The outer dimension of the frame 2 is 0 mm and the width is 13 mm.
The length is 0 mm and the length is 240 mm. Further, FIG. 2 is a view of this from the back side, and FIG. 3 is a cross-sectional view taken along the line AA ′ in FIG.

As shown in FIG. 1, a frame portion 2 is continuous around the upper side of the contents storage portion 1 whose upper surface is open. Reference numeral 4 is the bottom of the contents storage section. The thickness of the frame part is about 0.5 mm, which is the same as that of the contents storage part, but the frame has a bent part 11 as shown in FIGS. 2 and 3 to increase rigidity (in FIGS. 2 and 3). Material thickness is exaggerated). Of the four sides 2A, 2B, 2C, 2D of the frame part, 2A facing each other,
The hook portions 3A and 3B are provided on the back sides of the two sides of 2B, respectively. In addition, the product names are displayed in a raised manner on the upper surfaces of the frame portions on the two sides provided with the hook portions (not shown).

In this example, the protruding length of the hook portions 3A and 3B is larger than the position of the outer lower surface of the contents storage portion. Correspondingly, the side walls 5C and 5D of the other two sides of the contents storage portion are also extended to the same position as the protruding length of the hook portion. 6C in FIGS. 1 and 3
6D is a part thereof, and by doing so, it is possible to prevent the contents from spilling out from the gap formed on the contents storage portion when the trays are stacked.

At the side on which the hooks 3A, 3B are located, the hooks prevent the spillage, but the side walls 5A, 5B are extended in the same manner as described above, so that the side walls are more inside. You may stop spilling. It is within the scope of the present invention to provide such extension of the side wall portion and provision of a reinforcing rib as appropriate.

The outer bottom surface of the contents storage portion has a diameter of about 3 mm.
Although four protrusions 7A, 7B, 7C, 7D of mm are provided, the protrusion length from the contents storage portion is large, so the extension portions 6C, 6D of the side walls of the contents storage portion are partly in the middle.
The side surfaces of the protrusions are joined to each other to maintain strength.

Further, notches 8 for hanging a string are provided around the frame portion, but there are one in each of the sides 2A and 2B, and three in each of the sides 2C and 2D. There is. Then, reinforcing ribs 9 and 9 are provided on the back surface of the frame portion where the notches are provided.
A is provided. On the sides 2C and 2D, the reinforcing rib 9 is continuous with the side wall 5C (or 5D) of the content storage section, and on the sides 2A and 2B (9A), the side wall 5A (or 5B) of the content storage section. ) And Hama part 3A
(Or 3B).

The length of the reinforcing rib 9 protruding from the rear surface of the frame portion is the same as that of the extended portions 6C and 6D of the contents storage portion at the sides 5C and 5D, that is, the same as the hook portions 5A and 5B. It has become a length. Therefore, the reinforcing ribs also support the vertical force of the stacked trays similarly to the hook. On the other hand, the protruding length of the reinforcing rib 9A at the sides 5A and 5B is shorter than that of the hook portion.

Two holes 10 for draining water are provided in each of the side walls 5C and 5D of the contents storage section.

FIG. 4 is a view showing another embodiment. The difference from the above-mentioned embodiment is that the protruding length of the hook portion coincides with the outer lower surface of the contents storage portion. Only the cross-sectional view corresponding to FIG. 2 in which the differences are best seen is shown as FIG. Figure 4
2 in comparison with FIG. 2, the hook portions 3A and 3B are shortened, the extended portion 6C of the side wall 5C of the contents storage portion is eliminated, and the protrusions 7A and 7D are much shorter.
