Description

Egg packaging container

[0001] The present invention relates to an egg packaging container, and more specifically, to a stable egg packaging container in which eggs contained inside are not broken during storage or transportation.

[0002] The fresh food delivery market has been growing significantly recently due to rising consumer expectations regarding quality and freshness, as well as the increase in single-person households. In this delivery market, many issues regarding delivery quality are emerging, and among them, damage during delivery is appearing as a problem that cannot be easily resolved.

[0003] In particular, among fresh foods, eggs lose their marketability if they break during delivery, so measures to prevent damage are being prioritized. Specifically, solutions such as using special packaging materials or adding bubble wrap cushioning to protect the contents are being proposed to prevent egg damage during shipping. However, it remains difficult to completely prevent eggs from being damaged by impact.

[0004] In addition, even when cushioning materials such as bubble wrap are added, packaging takes an excessive amount of time, and excessive multi-packaging relative to the contents inevitably leads to increased waste and excessive plastic use. Ultimately, this can cause limitations in separate collection and recycling, landfill saturation, and marine pollution, so there is a need for research on innovative solutions that can minimize egg breakage while maintaining appropriate packaging.

[0005] A prior art regarding egg packaging containers is Korean Utility Model Registration No. 20-0484205, titled "Egg Packaging Container." Prior art No. 20-0484205 is configured to absorb external shocks by filling it with a cushioning material to prevent breakage by blocking shaking of the eggs during distribution and transportation. However, since prior art No. 20-0484205 uses a separate cushioning material inside the egg receiving groove, it has the problem of cumbersome packaging and increased complexity in the manufacturing and packaging processes.

[0006] Therefore, there is still a need for research on innovative solutions that enable proper egg packaging while minimizing egg breakage.

[0007] The present invention was derived from the aforementioned necessity, and the first objective of the present invention is to provide an egg packaging container that minimizes damage during the distribution and transportation of eggs, minimizes packaging time, and reduces environmental impact.

[0008] The second objective of the present invention is to provide an egg packaging container having a structure that is stably maintained against external impact and does not break without adding a separate filler.

[0009] The third objective of the present invention is to provide an egg packaging container capable of preventing external impact from being directly transmitted to the egg by forming a stable egg receiving structure by forming an egg receiving support member having a protruding surface in the egg receiving groove at the bottom and forming an egg receiving cover with an exposed hole at the top, so as to stably receive the egg from the top and bottom.

[0010] The objective of the present invention as described above can be achieved by providing an egg packaging container comprising: an egg receiving groove formed corresponding to a part of the eggshell shape of the egg, an egg receiving rim extended along the upper edge of the egg receiving groove, and an egg receiving body portion for receiving and seating an egg in the egg receiving groove; and a packaging cover portion arranged to cover the upper surface of the received egg, wherein the egg receiving body portion has an egg receiving support portion formed on the inner side of the receiving groove and protruding into the receiving groove so as to contact one side of the received egg, and the packaging cover portion includes an egg receiving cover having an exposure hole formed to expose a part of the upper surface of the received egg and a cover rim extended along the outer periphery of the egg receiving cover, and wherein the egg receiving cover has a plurality of slits formed leading to the exposure hole.

[0011] The egg tray support may be formed so that the lower part of the received egg protrudes so as to be spaced apart from the bottom surface of the receiving groove and contacts one side of the received egg.

[0012] The egg seat support may be formed with a plurality of mutually spaced protruding surfaces or with a band-shaped protruding surface that is integrally connected.

[0013] The egg tray main body is formed with a plurality of egg receiving grooves that are spaced apart from each other and connected, and a through-fixing member protruding upward from the connecting portion between the plurality of egg receiving grooves is further formed, and the packaging cover part is formed with a plurality of egg tray covers that are spaced apart from each other and a through-fixing hole is further formed from the connecting portion between the plurality of egg tray covers, and the through-fixing member may be arranged to pass through the through-fixing hole so as to fix the egg tray main body and the packaging cover part to each other.

[0014] Here, the connecting portion between the egg tray covers, in which through-fixing holes are formed, is formed to protrude downward, and a cover support portion that holds the contained egg from above may be further formed on the protruding side. The cover support portion may also be formed with a plurality of mutually spaced protruding surfaces similar to the egg tray support portion.

[0015] The egg tray cover may elastically contact a portion of the upper surface of the egg received along the boundary of the exposed hole.

[0016] According to one embodiment of the present invention as described above, damage to eggs during distribution and transportation can be minimized, packaging time can be minimized, and environmental impact reduced.

[0017] In addition, the structure itself remains stable against external impacts and does not break, even without the addition of separate filler material.

[0018] In addition, through an egg receiving structure capable of stably accommodating and fixing eggs from the top and bottom, it has the effect of forming a structure that can actively respond to differences in egg size, namely the width and level of the eggs.

[0019] In addition, by securing the egg so that it does not touch the bottom and forming a structure where the egg tray lid presses down firmly to keep it suspended in the air without shaking, it secures the egg so that it does not shake during transport or in vibrating situations, thereby effectively preventing external impacts from being directly transmitted to the egg.

[0030] Egg packaging container

[0031] The egg packaging container (5) of the present invention is configured with an egg tray main body (10) at the bottom and a packaging cover (20) at the top to stably accommodate eggs from the top and bottom, thereby forming a stable egg receiving structure and preventing external impact from being transmitted to the eggs contained within the container.

[0032] FIGS. 1 to 7 illustrate an embodiment of the present invention, wherein an egg packaging container capable of holding six eggs is used as an embodiment. However, the present invention may be applied as is to an egg packaging container capable of holding one egg, and may likewise include an embodiment of an egg packaging container capable of holding a plurality of eggs.

[0033]

[0034] FIG. 1 is a perspective view showing the overall configuration of the egg packaging container (5) of the present invention. The egg packaging container of the present invention is composed of an egg tray body (10) and a packaging cover (20), and is manufactured using recycled pulp or biodegradable synthetic resin as the main material. The thickness of the egg tray body (10) can be set to 1 to 3 mm, and the thickness of the packaging cover (20) can be set to 1 to 3 mm. It is preferable to manufacture it as a lightweight material by setting the overall density to within the range of 0.1 to 0.3 g / cm³. Such material and thickness can be appropriately selected to ensure sufficient strength while maintaining environmentally friendly characteristics.

[0035] FIG. 2 is a plan view of the present invention, clearly showing the arrangement of the egg receiving groove (110) formed in the egg tray main body (10) and the structure of the packaging cover part (20). The egg receiving groove (110) is formed concavely to match the shape of the lower part of the egg, and it is preferable that its depth be set to about 1 / 2 of the height of the egg. Here, the eggshell shape refers not to the entire shape of the eggshell, but to a part of the shape of the eggshell, that is, a part of the shape including the bottom and side of the egg being received. The egg tray rim (120) formed along the top of the egg receiving groove (110) is combined with the cover rim (220) of the packaging cover part (20) to perform a primary protection function against external impact.

[0036] FIG. 3 is a front view of the present invention, showing in detail the internal structure of the egg tray main body (10). In particular, the structure of the egg tray support part (130) formed on the inner surface of the receiving groove (110) is clearly shown. The egg tray support part (130) protrudes to a height of about 3 to 10 mm, which serves to separate the egg from the bottom surface of the receiving groove so that it does not come into direct contact with the egg, while effectively absorbing lateral impact. The egg tray support part (130) may be formed with a plurality of mutually spaced protruding surfaces or a band-shaped protruding surface that is integrally connected, and it is preferable that each of the plurality of protruding surfaces be formed as a curved surface corresponding to the contour of the eggshell to contact one side of the received egg.

[0037] FIG. 4 is a perspective view showing the egg tray body (10) in a state where an egg is actually contained. A protruding through-fixing member (116) is formed in the connecting part (114) between the egg receiving grooves (110), with a height greater than half the egg. This through-fixing member (116) is a structure for coupling with the packaging cover part (20) and serves to increase the stability of the packaging. The through-fixing member (116) protrudes upward from the connecting part (114) between the multiple egg receiving grooves, so that the rigidity of the entire structure can be secured when coupled with the through-fixing hole (216) of the packaging cover part (20).

[0038] FIGS. 5 and FIGS. 6 are perspective views showing the structure of the packaging cover portion (20) from the bottom and top, respectively. The main feature of the packaging cover portion (20), the exposed hole (212), is formed to a size of about 1 / 3 of the diameter of the top of the egg, and 6 to 8 slits (S) extending radially from this exposed hole are arranged at uniform intervals. The length of the slits is set to about 1 to 1.5 times the radius of the exposed hole. This slit structure allows the egg tray cover (210) to make elastic contact with a portion of the upper surface of the egg contained therein. Here, elastic contact means that due to the slits (S) formed in the egg tray cover (210), the split pieces of the egg tray cover can have elasticity and restoring force favorable for deformation and restoration, so that these split pieces exert deformation and restoring force along the exposed part of the egg contained therein to gently press and fix the egg contained therein.

[0039] The cover rim (220) is designed with a width of 10 to 15 mm and is stably connected to the rim of the egg tray body (10). Additionally, the connecting portion (214) between the egg tray covers (210), in which a through fixing hole (216) is formed, is formed to protrude downward, and a cover support portion (230) that holds the contained egg from above is additionally formed on the protruding side. This cover support portion (230) is also formed with a plurality of mutually spaced protruding surfaces similar to the egg tray support portion (130) to complement the shock absorption function.

[0040] FIG. 7 is a final perspective view showing the packaging completely closed with the egg contained inside. In this state, the egg has a two-stage protection structure in addition to absorbing the primary impact at the rim. First, the impact is dispersed at the egg tray support, and second, the remaining impact is absorbed through the elastic deformation of the upper cut portion. Through this multi-stage protection structure, the egg can be effectively protected from various impacts that may occur during transportation.

[0041] The egg packaging container (5) of the present invention is manufactured through a pulp molding process, and a vacuum molding method or a compression molding method is used. During molding, the mold temperature is set to 150 to 180°C, the molding pressure is set to 5 to 7 kg / cm², and the drying temperature can be maintained at 100 to 120°C. The manufacturing method may be produced by making a mold of the opposite structure, such as plaster, wood, or metal, and attaching and drying pulp in the form of a slurry to such a mold. This manufacturing process is not limited to the mold manufacturing method, and various manufacturing processes may be applied. After molding, the edges may be trimmed, and cutting processing for forming a cut and surface treatment for imparting water resistance may be performed. In this case, the upper and lower parts (egg tray body part and packaging cover part) may be manufactured as a single unit, or each may be molded separately and connected to complete the whole.

[0042] Through such a structure and manufacturing method, the present invention has the advantage of safely protecting eggs without the need for separate fillers, while simultaneously enabling environmentally friendly packaging. In particular, the egg receiving structure, which stably accommodates and secures eggs from the top and bottom, effectively prevents external impacts from being directly transmitted to the eggs.

[0043] Furthermore, the egg receiving structure, capable of stably accommodating and securing eggs from both the top and bottom, ultimately functions to form a structure that can actively respond to differences in egg size—specifically, variations in width and level. In addition, by securing the eggs so they do not touch the bottom and forming a structure where the egg tray lid presses down firmly to prevent shaking and allows the eggs to float in the air, it secures the eggs to remain stable during transport or under vibrating conditions, thereby preventing external impacts from being directly transmitted to the eggs.
