[Figure 7] FIG. 10 is a plan view showing a blank plate of an egg packaging container according to a third embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0016] First Embodiment Embodiments of the present invention will be described below with reference to the drawings. Figure 1 shows a perspective view of an egg packaging container 1 according to a first embodiment. Egg packaging container 1 is formed into a rectangular parallelepiped by bending a blank plate 40 (see Figure 2) and is used to package boiled eggs. Egg packaging container 1 has a cylindrical body 10 whose top and bottom are closed by a top portion 7 and a bottom portion 17 (see Figure 4), respectively. Body 10 is formed by connecting a plurality of peripheral plates 11 to 14 (see Figure 2). Peripheral plates 12 and 14 face each other in the front-to-back direction, and peripheral plates 11 and 13 face each other in the left-to-right direction. That is, body 10 has two pairs of opposing peripheral plates 11 to 14.

[0017] The front peripheral plate 13 is provided with an opening section 6 having perforated cuts 4 extending in the left-right direction, arranged side by side above and below. Perforated cuts 4 extending from the upper end of the opening section 6 are provided on peripheral plates 12 (see Figure 2) and 14 adjacent to peripheral plate 13. In addition, the front peripheral plate 13 and the top surface 7 are provided with windows 5 through which the interior can be seen.

[0018] 2 shows a plan view of a blank plate 40 that forms the egg packaging container 1. The blank plate 40 is made of paper, and a paperboard such as coated cardboard can be used. The basis weight of the blank plate 40 is, for example, 200 to 450 g / m 2 The blank plate 40 may be formed from a resin sheet.

[0019] The blank plate 40 has approximately rectangular peripheral plates 11 to 14 that are connected in sequence in one direction via fold lines 3. A glue tab 15 is connected to the side of the peripheral plate 14 via the fold line 3. The peripheral plate 13 has a tear-open portion 6 formed by a plurality of notches 4. The peripheral plates 12 and 14 have perforated notches 4 that extend obliquely upward from the upper end of the tear-open portion 6. The perforated notches 4 of the peripheral plates 12 and 14 may also be formed to extend from the lower end of the tear-open portion 6.

[0020] The peripheral plate 11 and the adhesive strip 15 are provided with folding lines 3 extending horizontally, continuing from the cuts 4 on the peripheral plates 12 and 14, and cuts 4 are provided on the folding lines 3.

[0021] A top flap 8 is connected to the top of peripheral plate 11 via a fold line 3, and a bottom flap 18 is connected to the bottom via a fold line 3. A top plate 9 is connected to the top of peripheral plate 13, which faces peripheral plate 11 from the front to the rear, via a fold line 3, and a bottom plate 19 is connected to the bottom via a fold line 3.

[0022] The widths D1 and D3 of the bottom plate 19 and top plate 9, which are bent from the peripheral plate 13, in a direction perpendicular to the peripheral plate 13 (Y direction in FIG. 1), are approximately equal to the distance D0 (see FIG. 1) between the opposing peripheral plates 11 and 13. The widths D2 and D4 of the bottom flap 18 and top flap 8, which are bent from the peripheral plate 11, in a direction perpendicular to the peripheral plate 11 (Y direction in FIG. 1), are shorter than the widths D1 and D3 of the top plate 9 and bottom plate 19.

[0023] Below the peripheral plate 12, a lower plate 21, an opposing plate 22, and a support plate 23 are successively provided via a fold line 3, and below the support plate 23, an adhesive strip 24 is successively provided via a perforated cut 4. Similarly, below the peripheral plate 14, a lower plate 21, an opposing plate 22, a support plate 23, and an adhesive strip 24 are successively provided.

[0024] The width W1 of the bottom plate 21 bent from the peripheral plates 12, 14 in a direction perpendicular to the peripheral plates 12, 14 (X direction in Figure 1) is shorter than half the distance W0 (see Figure 1) between the opposing peripheral plates 12, 14. In addition, the support plate 23 and the opposing plate 22 are provided with a hole 25 that opens across both. The periphery of the hole 25 on the support plate 23 is formed by a circular arc. The bottom plate 21, opposing plate 22, support plate 23, and adhesive strip 24 form a bottom support portion 20 that supports the bottom of the egg E.

[0025] Support flaps 31 are connected above the peripheral plates 12, 14 via fold lines 3. The open ends of the support flaps 31 are provided with curved cutouts 32 whose peripheries are generally elliptical. The width W2 of the support flaps 31 folded from the peripheral plates 12, 14 in the direction perpendicular to the peripheral plates 12, 14 (X direction in Figure 1) is longer than half the distance W0 (see Figure 1) between the opposing peripheral plates 12, 14. The support flaps 31 form an upper support portion that supports the upper part of the eggs E.

[0026] 3 is a plan view showing intermediate body 41 of egg packaging container 1. Blank plate 40 is bent between bottom plate 21 and opposing plate 22, and adhesive tabs 24 are adhered to the inner surfaces of peripheral plates 12 and 14. Next, blank plate 40 is bent between peripheral plates 11 and 12 and between peripheral plates 13 and 14, and adhesive tab 15 is adhered to the inner surface of peripheral plate 11. In this way, intermediate body 41 having a cylindrical body 10 is formed.

[0027] Fig. 4 shows a longitudinal cross-sectional view of egg packaging container 1, and Fig. 5 shows a view seen from arrow A in Fig. 4. Intermediate body 41 (see Fig. 3) is bent between peripheral plates 12 and 13 and between peripheral plates 11 and 14 to raise body portion 10, and bottom support portion 20 is raised from peripheral plates 12 and 14.

[0028] As a result, the bottom plate 21 is bent horizontally inward from the lower ends of the opposing peripheral plates 12, 14, and each opposing plate 22 is bent upward from the inner end of each bottom plate 21 to face each other. Each support plate 23 is bent horizontally outward from the upper end of the opposing plate 22, and the adhesive strip 24 is bent upward from the outer end of the support plate 23 and adhered to the inner surface of the peripheral plates 12, 14. As a result, the periphery of the hole 25 forms the bottom support portion 20 that supports the bottom of the egg E. The periphery of the hole 25 on the support plate 23 is formed by a circular arc, but may also be formed by a polygon.

[0029] Next, bottom flaps 18 are folded from peripheral plate 11 (see FIG. 2) to cover the outer surface of lower plate 21. Bottom plate 19 is folded from peripheral plate 13 (see FIG. 2) and adhered to the outer surface of bottom flaps 18. Bottom flaps 18 and bottom plate 19 form bottom portion 17 that covers the bottom surface of body 10.

[0030] After the bottom support portion 20 and the bottom portion 17 are formed, a pair of support flaps 31 are folded from the peripheral plates 12 and 14, respectively, and inserted into the body portion 10. Then, an egg E is inserted into the body portion 10 from the top opening of the body portion 10 along the support flaps 31 and placed on the bottom support portion 20.

[0031] At this time, the bottom of the egg E is supported by the periphery of the hole 25 of the bottom support part 20. Furthermore, due to the elasticity of the support flap 31, the periphery of the notch 32 abuts against the top of the egg E, supporting the top of the egg E. Therefore, the support flap 31 constitutes an upper support part that supports the top of the egg E.

[0032] The upper support portion that supports the upper part of the eggs E may have other configurations. For example, support flap 31 having a fitting hole may be provided on only one of peripheral plates 12, 14, and support flap 31 folded back from the peripheral plate may be arranged in an L-shape to support eggs E by the fitting hole. However, as in this embodiment, by providing support flaps 31 on peripheral plates 12, 14 with width W2 that is longer than half the distance W0 (see FIG. 1) between opposing peripheral plates 12, 14, the upper part of eggs E is elastically supported. This is more preferable because it allows eggs E to be stably supported when packaged.

[0033] After eggs E are inserted into body 10, top flaps 8 are folded from peripheral plate 11 (see FIG. 2), and top plate 9 is folded from peripheral plate 13 (see FIG. 2) and bonded to the outer surface of top flaps 8. Top flaps 8 and top plate 9 form top portion 7 that covers the top surface of body 10. In this way, eggs E are packaged in egg packaging container 1.

[0034] Alternatively, intermediate body 41 may be loaded into an automatic packaging machine, which then forms egg packaging container 1 and fills and packages eggs E. In this case, because intermediate body 41 has a shape in which folding pieces are provided on the top and bottom of each peripheral panel of body 10, a general cartoner that forms a rectangular box and fills it with contents can be used.

[0035] When eggs E are to be removed, opening portion 6 on peripheral plate 13 is pulled from one end and cut off, and peripheral plates 12 and 14 are cut along perforated notches 4. As a result, the upper part of egg packaging container 1 is folded along fold line 3 on peripheral plate 11, and eggs E are removed.

[0036] According to this embodiment, bottom support parts 20 are provided on each of a pair of opposing peripheral plates 12, 14 of body part 10. Therefore, the bottom of egg E placed on bottom support part 20 is fitted into hole 25 and supported, and then top part 7 is closed. This eliminates the need to hold eggs E in a sandwiched state when assembling egg packaging container 1, making it easy to package eggs E and reducing egg packaging costs.

[0037] Bottom support part 20 has bottom plates 21 bent horizontally inward from the lower ends of peripheral plates 12, 14, opposing plates 22 bent upward from the inner ends of each bottom plate 21 to face each other, support plates 23 bent horizontally outward from the upper ends of opposing plates 22, adhesive strips 24 bent upward from the outer ends of support plates 23 and adhered to the inner surfaces of peripheral plates 12, 14, and holes 25 that open across support plates 23 and opposing plates 22. This makes it easy to realize bottom support part 20 that supports the bottom of eggs E. In addition, intermediate body 41 with adhesive strips 24 adhered to peripheral plates 12, 14 can be loaded into an automatic packaging machine, allowing egg packaging container 1 to be easily assembled.

[0038] Additionally, the upper support portion that supports the upper portion of the eggs E has support flaps 31 that are bent inward from the upper ends of the pair of opposing peripheral plates 12, 14. Support flap 31 has a width W2 in the direction perpendicular to peripheral plate 12 that is longer than half the distance W0 between peripheral plates 12, 14, and has notches 32 at its open end. The elasticity of support flap 31 causes the periphery of notch 32 to abut against the upper portion of egg E, thereby supporting the upper portion of egg E. This allows eggs E to be stably supported when packaged.

[0039] In addition, the top portion 7 has a top flap 8 bent from the upper end of one of a pair of peripheral plates 11, 13, which are different from the peripheral plates 12, 14 on which the upper support portion is provided, and a top plate 9 bent from the upper end of the other and adhered to the outer surface of the top flap 8. This makes it easy to realize the top portion 7 that covers the top surface of the body 10.

[0040] In addition, bottom portion 17 has bottom flap 18 that folds from the lower end of one of the pair of peripheral plates 11, 13, which are different from peripheral plates 12, 14 on which bottom support portion 20 is provided, to cover lower plate 21, and bottom plate 19 that folds from the lower end of the other and is adhered to the outer surface of bottom flap 18. This makes it easy to realize bottom portion 17 that covers the bottom surface of body 10.

[0041] Furthermore, a strip-shaped tearing portion 6 that can be cut horizontally is provided on one surface (peripheral plate 13) of the body 10, and perforated notches 4 extending from the upper or lower end of the tearing portion 6 are formed on the surfaces (peripheral plates 12, 14) adjacent to said one surface. This makes it possible to easily remove the eggs E by cutting out the tearing portion 6 and cutting the peripheral plates 12, 14 along the notches 4.

[0042] Second Embodiment Next, Figure 6 shows a plan view of a blank plate 40 forming an egg packaging container 1 of a second embodiment. For ease of explanation, the same parts as those of the first embodiment shown in Figures 1 to 5 above are given the same reference numerals. The egg packaging container 1 of this embodiment has a longer distance D0 (see Figure 1) in the front-to-rear direction (Y direction) than the first embodiment, and can store two eggs E. Other parts are the same as those of the first embodiment.

[0043] The width of the pair of opposing peripheral plates 12, 14 is twice that of the first embodiment. A bottom support portion 20 is connected to the lower part of each of the peripheral plates 12, 14, and a support flap 31 is connected to the upper part of each of them. Two holes 25 are arranged side by side in the Y direction in the bottom support portion 20, and two notches 32 are arranged side by side in the Y direction in the support flap 31. In addition, a window portion 5 is provided across the front peripheral plate 13 and the top plate 9, and also across the rear peripheral plate 11 and the top flap 8.

[0044] Further, tear-open portion 6 is formed on peripheral plate 12, and peripheral plates 11 and 13 adjacent to peripheral plate 12 are provided with perforated notches 4 extending obliquely upward from the lower end of tear-open portion 6. A fold line 3 extending horizontally continuous with notch 4 on peripheral plate 13 is provided on the upper part of peripheral plate 14, and notch 4 is provided on said fold line 3.

[0045] This allows egg packaging container 1 to package two eggs E (see Figure 3) lined up in the Y direction. When eggs E are to be removed, opening portion 6 on peripheral panel 12 is pulled and cut from one end, and peripheral panels 11 and 13 are cut along perforated notches 4. This causes the upper part of egg packaging container 1 to fold along fold line 3 on peripheral panel 14, and eggs E are removed.

[0046] As in the first embodiment, in this embodiment, there is no need to hold the eggs E in a sandwiched state when assembling the egg packaging container 1, and therefore the eggs E can be easily packaged. Furthermore, an intermediate body in which adhesive strip 15 is adhered to peripheral plate 11 and adhesive strip 24 is adhered to peripheral plates 12, 14 can be loaded into an automatic packaging machine, and the egg packaging container 1 can be easily assembled.

[0047] <Third embodiment> Next, Figure 7 shows a plan view of a blank plate 40 forming an egg packaging container 1 of a third embodiment. For ease of explanation, the same parts as those of the first embodiment shown in Figures 1 to 5 are given the same reference numerals. In this embodiment, the top flaps 8 and bottom flaps 18 (see Figure 2) of the first embodiment are omitted. The other parts are the same as those of the first embodiment.

[0048] The upper and lower portions of the peripheral plate 11 are empty spaces because the top flap 8 and bottom flap 18 (see FIG. 2) of the first embodiment are omitted. A bottom plate 19 and a bottom insert piece 19a are connected in this order below the peripheral plate 13 via a fold line 3, and an upper plate 9 and an upper insert piece 9a are connected in this order above the peripheral plate 13 via a fold line 3.

[0049] The bottom plate 19 is bent from the peripheral plate 13 and placed on the lower plate 21 of the bottom support part 20. The bottom insertion piece 19a is bent from the bottom plate 19 and inserted into the inner surface of the peripheral plate 11. As a result, the bottom plate 19 and the bottom insertion piece 19a form the bottom part 17 (see Figure 3) that covers the bottom surface of the body part 10.

[0050] The top plate 9 is bent from the peripheral plate 13, and the top insertion piece 9a is bent from the top plate 9 and inserted into the inner surface of the peripheral plate 11. As a result, the top plate 9 and the top insertion piece 9a form the top portion 7 (see Figure 3) that covers the top surface of the body 10.

[0051] As in the first embodiment, in this embodiment, there is no need to hold the eggs E in a sandwiched state when assembling the egg packaging container 1, and therefore the eggs E can be easily packaged. Furthermore, an intermediate body in which adhesive strip 15 is adhered to peripheral plate 11 and adhesive strip 24 is adhered to peripheral plates 12, 14 can be loaded into an automatic packaging machine, and the egg packaging container 1 can be easily assembled.

[0052] In addition, the top surface portion 7 has a top surface plate 9 bent from the upper end of one of a pair of peripheral plates different from the peripheral plates 12, 14 on which the upper support portion is provided, and a top surface insertion piece 9a bent from the tip of the top surface plate 9 and inserted into the inner surface of the other. This makes it easy to realize the top surface portion 7 that covers the top surface of the body portion 10.

[0053] In addition, bottom portion 17 has bottom plate 19 that is bent from the lower end of one of a pair of peripheral plates different from peripheral plates 12, 14 on which bottom support portion 20 is provided to cover lower plate 21, and bottom insertion piece 19a that is bent from the tip of bottom plate 19 and inserted into the inner surface of the other bottom plate. This makes it easy to realize bottom portion 17 that covers the bottom surface of body 10.

[0054] In this embodiment, one of the top surface portion 7 and the bottom surface portion 17 may be formed in the same manner as in the first embodiment. That is, the top surface portion 7 may be formed by a top flap 8 and a top plate 9, and the bottom surface portion 17 may be formed by a bottom flap 18 and a bottom plate 19. [Industrial Applicability]
