DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. As shown in FIGS. 1 to 4, the egg container of the present invention has at least one egg container (a total of three eggs in the illustrated example). The container body (A1) (A2) (A3) having the configuration, and one common lid (B) that can be covered interchangeably with each container body (A1) (A2) (A3). Consists of

In addition, each container body (A1) (A2)
Both (A3) and the lid (B) are vacuum-formed from polyethylene terephthalate, polystyrene, or other thin transparent or translucent thermoplastic plastic sheet materials into square planar contours of almost the same size. I have.

The approximately square size is, for example, about 290.
If it is selected to be mm x 290 mm, the egg containers of the present invention can be stably stored and transported in a commercially available standard-size transport container (not shown) as a pair of paralleled egg containers without rattling, This is extremely convenient for distribution because there is no need to prepare and prepare a new special transport container.

As the plastic sheet material, a recycled material instead of a virgin material, an antibacterial sheet material effective for suppressing the growth of bacteria attached to eggs, and the like can be used.

First, each container body (A1) formed into a three-dimensional shape from a plastic sheet material by the vacuum forming die.
(A2) The configuration of (A3) will be described with reference to FIGS. 5 to 12 showing a single unit.
1) A pair of left and right handle flanges formed to protrude with a constant band width (for example, about 25 mm) (w) only on two parallel sides of (A2) and (A3), excluding both handle flanges (1a). The central part of the container bodies (A1), (A2) and (A3) has a rectangular (for example, a size of about 240 mm × 290 mm) planar contour shape.

This is a container body (A1) (A2) without both handle flanges (1a). 4) The entire four sides including the remaining two parallel sides of (A3) are continuously trimmed and reinforced. Therefore, both handle flanges (1a) of the container body (A1) (A2) (A3) can be stably carried by both hands.

In addition, the flat surfaces of both handle flanges (1a) are provided with notched concave / convex groups (3a) for preventing close contact between the container bodies also by the forming surface of a vacuum forming die. Each of the protrusions of the notched concave / convex group (3a) is distributed as a quadrangular pyramid or the like protruding upward, and the flat surfaces of both handle flanges (1a) are also provided with a smooth suction surface (4a) by an automatic suction disk. ) Are also defined so as to secure a blank portion in the notched unevenness group (3a).

As shown in FIG. 5, the suction smooth surface (4a) is a pair of left and right sides symmetrical with respect to both handle flanges (1a), thereby dividing the notched unevenness group (3a). Rectangular in plan view (for example, about 25 mm x 50 mm
Is preferably distributed in parallel.

Here, the suction smooth surface (4a) of the handle flange (1a) is a container body (A1) (A2) prepared in a flat stacked state in which the egg storage recesses described later fit together.
When a large number of (A3) are sucked by an automatic suction machine (not shown) such as soccer or the like in order to transfer a large number of (A3) one by one onto a belt conveyor of an automatic egg packaging line, the suction power of the suction machine is reduced (vacuum). This is to prevent air leakage.

Further, adjacent container bodies (A1), (A2), and (A3) prepared in a stacked state as described above are likely to be closely adhered and integrated by a charging action or the like. Since it is difficult to accurately suck and separate each sheet, the above-mentioned notch group (3a) is also provided as a preventive measure, and the notch group (3a) is provided with the handle flange (3). 1
It also serves as a reinforcing bead in a).

m) Egg storage recess (6a) that sinks downward by (d1)
Are partitioned into grids in which the adjacent eggs (E) do not touch each other.

The flat top surface of the partition lattice wall (5a), which is perpendicular to the vertical and horizontal directions, is at almost the same height as the plane of the handle flange (1a), and each of the egg storage recesses depressed from the height position. The portion (6a) has a substantially truncated octagonal pyramid shape that gradually becomes narrower downward.

(7a) is a conical or frusto-conical fitting concave groove which is inverted and depressed upward from the center of the flat bottom surface in each egg storage recess (6a). A1) (A2) (A3) Ensure stability when stacking one another.

(8a) is an egg catching step surface provided at a mid-height position on the outer peripheral surface of each egg storage recess (6a). The egg (E) is placed on the bottom surface in the storage recess (6a). It functions as an annular lateral rib that reinforces the wall surface of the egg storage recess (6a) while preventing it from being inadvertently damaged by receiving it in a storage state that rises from the upper surface.

(9a) is the partition lattice wall (5a)
Is a middle partitioning convex wall that is raised tall by a fixed height (for example, about 15 mm) (h1) from the vertical and horizontal orthogonal portions to the opposite of the egg storage recess (6a). Egg storage recesses (6
Continuing with the wall surface of (a), it has a substantially truncated octagonal pyramid shape that gradually becomes thinner as it goes upward.

In addition, of the plurality of intermediate partitioning convex walls (9a), only four, which are interspersed at four corners, and two, which are symmetrically located at the intermediate position, are limited to a total of six. From the center of the flat top surface, a conical or frusto-conical fitting projection (10a) is raised upward, which is provided on the bottom surface of each egg storage recess (6a). Corresponding to the fitting groove (7a).

Further, the partition lattice wall (5a) intersects at right angles with both handle flanges (1a) forming two parallel sides of the container body (A1), (A2) and (A3); (5a) is the container body (A1) (A2) (A
From the part that intersects the remaining two parallel sides at a right angle and the four corners of the container body (A1) (A2) (A3),
Each of the peripheral partitioning convex walls (11a) is raised upward and tall by the same constant height (h1) as the intermediate partitioning convex wall (9a), and a plurality (a total of 22 in the figure) of peripheral partitioning convex walls are provided. (11a) also participates in the formation of the compartment for the egg storage recess (6a).

That is, the container body (A1) (A2)
Each of the egg storage recesses (6a) distributed in the central portion having the rectangular planar contour shape in (A3) is formed by the partition lattice wall (5a), the intermediate partition convex wall (9a), and the peripheral partition convex wall (11a). 5 and 12, the openings are formed to have substantially the same size and open in a substantially regular octagon in plan view.

Each of the egg storage recesses (6
On the entire wall surface of (a), a group of vertical ribs for exerting the supporting strength of the egg (E) is provided with the above-mentioned annular horizontal rib (eg, the egg receiving step surface (8)).
Although the strips are arranged along the vertical direction as the uneven stripes orthogonal to a)), the reference symbols of the vertical rib groups are omitted.

In this case, a total of 14 peripheral partitioning convex walls (11a) protruding from a portion intersecting at right angles between the partitioning lattice wall (5a) and both handle flanges (1a) are formed by a plane shown in FIGS. As is apparent from the figure, about half of the outer side is a special fitting guide convex wall portion (12a) with the lid (B), and is in a laterally extended state in which each handle flange (1a) overlaps from above. In addition, the fitting guide convex wall portion (12a) guides the fitting with the lid (B) and can also function as a supporting bone for preventing the handle flange (1a) from being deformed illegally. .

However, of the fourteen peripheral partitioning convex walls (11a) scattered and distributed as a total of fourteen, a total of four symmetrical left and right pairs facing the smooth surface for suction (4a) of both handle flanges (1a). In particular, there is no special fitting guide convex wall portion (12a) that overlaps the handle flange (1a) from above, and the so-called cut-out flat outer wall has a handle flange (1a). Of the handle, and the handle flange (1)
The automatic sucking machine such as the soccer can be surely sucked to the smooth surface (4a) for suction of (a) without any trouble.

On the other hand, the container body (A1) (A2) (A3)
The remaining parallel 2 without the handle flange (1a) at
A total of 12 (although four of the four corners are overlapped) peripheral partitioning convex walls (11a) protruding from a portion which intersects the side and the partitioning lattice wall (5a) at a right angle also have these Also does not have the special fitting guide convex wall portion (12a), and the flat outer wall surface in the notched form is folded by the container body (A1) (A2) (A3). It is almost flush with the bending peripheral piece (2a).

The fitting projections (10a) corresponding thereto are not provided on all of the intermediate partitioning convex walls (9a), but are provided as four pairs scattered at four corner positions and a pair of right and left symmetrical at the intermediate position. It is only partially provided for a total of six including two intervening ones.

The reason is that the intermediate partition convex wall (9a)
If the fitting protrusions (10a) are provided on all of the pieces, it becomes rather difficult to fit the fitting recesses (7a) of the respective egg storage recesses (6a), and the accurate fitting state can be quickly obtained. Not only that, there are many restrictions on the molding of the container bodies (A1), (A2), and (A3).

Each container body (A1) (A2) (A3)
Has the same configuration as described above, so that in the empty state where the eggs (E) are not stored in the respective egg storage recesses (6a), the directions thereof are alternately changed by 90 degrees. If they are stacked without being stacked, the egg storage recesses (6a) of the adjacent container bodies (A1) (A2) (A3) as shown in FIG.
Comrades can fit themselves properly, and as a result, can be maintained in a very flat stacked state, which is extremely convenient for storage when not in use, collection and recycling of waste, and the like.
