Description

[Detailed Description of the Invention] The present invention relates to an egg container comprising a cylindrical inner case and an outer case.

That is, the present invention involves winding a rectangular piece of corrugated cardboard or paperboard into a cylindrical shape, providing a plurality of approximately circular notches in a row on the circumferential surface, and extending each of the notches toward the inside of the cylinder. A row of recesses are formed by bending to accommodate the eggs, and an engaging side piece is provided protruding from the edge of the base material, and the engaging side piece is bent and engaged with the recess for bonding. The structure consists of a fixed cylindrical inner case and a cylindrical outer case removably attached to the inner case without using any fixing means such as, etc., and the inner case that houses the eggs is particularly easy to assemble. To provide an egg container which can be formed into a shape, can hold eggs in a stable state, and is also excellent in decoration due to its unique cylindrical shape as a whole.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, 1 is an inner case made of cardboard wound into a cylindrical shape, and 2 is an outer case made of cylindrical paperboard that is removably attached to the circumferential surface of the inner case 1. It is.

The inner case 1 uses a substantially rectangular single-cardboard base material a as shown in FIGS. 4 and 5 in the unfolded state, and has substantially circular cut portions 3° 3... ... are arranged in a row at regular intervals.

As for the notches 3.3, the portions indicated by solid lines in FIG. 5 are cut out, and the portions indicated by dotted lines are not cut out and are bent lines to prevent them from falling off.

Furthermore, transverse lines 4, 4, . . . are provided in the portions surrounded by the cut portions 3, 3, .

5, 5... are semicircular engaging side pieces protruding from the other side edge of the base material a at positions corresponding to the respective notches 3, 3... There are neck parts 6, 6, etc., which can be bent freely.

7, 8, 7, 8 are a pair of engaging pieces protruding from both ends of the base material a in the longitudinal direction adjacent to each other, and are folded at the respective bending lines 9, 9... The engaging pieces 7, 7 have protrusions 10, 10 formed at the tips of the engagement pieces 7, 7, and the recesses 11, 11 engage with the protrusions 10, 10 at the tips of the other engaging pieces 8, 8. is formed.

Therefore, when forming the inner case 1, the base material a is wound into a cylindrical shape and the notches 3, 3... are bent inward to form the recesses b... Then, each of the engaging side pieces 5, 5... is bent into the recessed part b..., and then the engaging pieces 7, 8 adjacent to each other at both ends of the cylinder are bent.
is bent inward at bending lines 9 and 9 and pushed into the cylinder, and the protruding piece 10 is engaged with the recess 11, thereby forming a stable cylindrical shape without using any fixing means such as adhesive. .

Further, the outer case 2 is provided with window holes 12, 12, which also serve as decorations, at positions that do not match the recesses b, . . . when the outer case 2 is completely covered with the inner case 1.

In the egg container formed in this way, the recesses arranged in a row in the inner case 1, b... are transverse lines 4, 4...
As shown in FIG.
In order to flexibly form ...... and d, d..., eggs e, e..., which are adjacent to each recess, b......・Can be accommodated without colliding with each other.

Furthermore, the engaging side pieces 5, 5... are the notch portions 3.
, 3... are formed by bending the end walls c, d and the side surface of the egg e to form a recess without being pulled out, b...
... Since the inner case 1 is engaged with the inside, the inner case 1 can be firmly held in a cylindrical shape.

Furthermore, in this embodiment, the inner case 1 is formed of a single piece of corrugated cardboard, and each recess (a), (b), etc. is surrounded by a cushioning material.

e... can be held safely and reliably, and by attaching the outer case 2 to the inner case 1, the cylindrical shape of the inner case 1 can be stabilized, and the egg can be held soft without applying pressure. It is possible to keep the shape suspended in the air.

In addition, in the case shown in FIGS. 8 to 10, the inner case 1 is made of cardboard and the outer case 2 is made of paperboard, contrary to the case where the inner case 1 is made of cardboard and the outer case 2 is made of paperboard. It is made of single-sided corrugated cardboard.

Although the inner case 1 of this embodiment lacks elasticity, it has good shape stability, and the outer case is made of corrugated cardboard to provide excellent cushioning properties.

As described above, in the present invention, the cylindrical inner case that houses the eggs forms both end walls in the longitudinal direction of each recess, and the engaging side pieces on the side edges are bent and faced into each recess. It is designed to maintain its cylindrical shape, so it is easy to assemble.
No fixing means such as adhesive is required.

Furthermore, since each recess has a cushioning property and is isolated, there is no risk of adjacent eggs colliding and breaking.

Furthermore, since the entire container has a cylindrical shape, it is easy to handle, and there is an advantage in that a large number of containers can be handled and replaced without any gaps during packaging.

Furthermore, because of its excellent decorative appearance, it has many advantages, such as being suitable for use in packaging containers for hot spring eggs as souvenirs from hot spring resorts and the like.
