また、卵収納凹部２に卵７を収納すると、卵７の側面７’が当接する截頭ほぼ４角錐形支柱５の突条４’，４”の突出側部４ｂ，４ｂ’は、卵収納凹部２の方向に突出する凸状面Ｐを有しているので、上記卵収納凹部２内に卵７を収納しても上記突条４’，４”は容易に潰れることがなく、隣接する卵同士の間隔を維持し得るので、卵同士の接触による卵の損傷を効果的に防止することができる。   Further, when the egg 7 is stored in the egg storing recess 2, the protruding side portions 4 b and 4 b ′ of the protrusions 4 ′ and 4 ″ of the truncated quadrangular pyramid support 5 on which the side surface 7 ′ of the egg 7 abuts are stored in the egg storage. Since it has the convex surface P which protrudes in the direction of the recessed part 2, even if it accommodates the egg 7 in the said egg accommodation recessed part 2, the said protrusion 4 ', 4 "is not easily crushed, but adjoins. Since the distance between the eggs can be maintained, damage to the eggs due to the contact between the eggs can be effectively prevented.

また、上記各卵収納部２に卵７を収納すると、隣接する卵７同士には、その間に存在する上記突条４’，４”の上記突出側部４ｂ，４ｂ’により、互いに離間する方向に押される力が働き、その結果、両卵７，７の中心は、卵収納凹部２，２の中心Ｇ，Ｇより若干左右に振られた位置（卵７，７同士の間隔Ｘが広がる方向の位置）に位置付けられる（図７参照）。   Further, when the eggs 7 are stored in the respective egg storage portions 2, the adjacent eggs 7 are separated from each other by the protruding side portions 4 b and 4 b ′ of the protrusions 4 ′ and 4 ″ existing therebetween. As a result, the center of both the eggs 7 and 7 is moved slightly to the left and right of the centers G and G of the egg storage recesses 2 and 2 (the direction in which the interval X between the eggs 7 and 7 increases). (Refer to FIG. 7).

そして、卵収納用容器１全体でみると、上記各卵収納凹部２に収納された卵７は、互いに容器１の外側縁に直交する外側に向いた方向（矢印Ｍ，Ｍ’方向）に振られた位置に位置付けられ、これにより、前後方向に隣接する卵７同士の接触を効果的に防止することができる（図７参照）。   When the egg storage container 1 is viewed as a whole, the eggs 7 stored in the respective egg storage recesses 2 are swung in the directions (arrows M and M ′ directions) facing toward the outside perpendicular to the outer edge of the container 1. Thus, contact between eggs 7 adjacent to each other in the front-rear direction can be effectively prevented (see FIG. 7).

また、上記コーナ部に位置する４つの卵収納凹部２に収納した卵７は、上記４角錐形支柱５の「Ｌ」字状に位置する各突条４’の上記突出側面部４ｂ，４ｂ’が上記各卵７の側面７’に当接することによって、卵収納用容器１のコーナ部を２等分する外側方向（矢印Ｚ方向）に振られた位置に位置付けられ、これにより、前後方向、左右方向に位置する卵７同士の接触を効果的に防止することができる。   Further, the eggs 7 stored in the four egg storage recesses 2 positioned at the corner portions are the protruding side surface portions 4b and 4b ′ of the protrusions 4 ′ positioned in the “L” shape of the quadrangular pyramid-shaped column 5. Is positioned in a position swung in the outer direction (arrow Z direction) that bisects the corner portion of the egg storage container 1 by contacting the side surface 7 'of each egg 7, Contact between the eggs 7 positioned in the left-right direction can be effectively prevented.

尚、図２中、左右方向に一列に並ぶ５個の卵をより詳細に検討すると、両端のコーナ部に位置する２個の卵が各々矢印Ｚ方向（外側）に振られる結果、中央部に並列する３つの卵の内、中央に位置する卵の左右に位置する卵は中央の卵から左右に離間する方向（矢印Ｎ，Ｎ’方向）に振られるため（図７参照）、結果として、左右方向に並列する５個の卵は、左右方向においても、何れも互いの間隔が離間する方向に位置付けられることになる。   In addition, in FIG. 2, when examining the five eggs arranged in a line in the left-right direction in more detail, as a result of the two eggs positioned at the corners at both ends being respectively swung in the arrow Z direction (outside), Of the three eggs in parallel, the eggs located on the left and right of the egg located in the center are swung in the direction (arrow N, N ′ direction) away from the center egg (see FIG. 7). The five eggs juxtaposed in the left-right direction are all positioned in the direction in which the interval between them is separated in the left-right direction.

また、上記４箇所の突条４’，４”の上記下端部幅Ｔを拡大することにより、卵収納凹部２間の前後左右の隣接収納卵７相互の間隙を拡大することができ、搬送される卵収納用容器内の収納卵同士の接触による卵の損傷を効果的に防止することができる。   Further, by expanding the lower end width T of the four protrusions 4 ′, 4 ″, the gap between the front and rear left and right adjacent storage eggs 7 between the egg storage recesses 2 can be expanded and transported. Egg damage due to contact between the stored eggs in the egg storage container can be effectively prevented.

また、図３に示すように、截頭ほぼ４角錐形支柱５の４個の角部がそれぞれ上下方向の突条４’，４”によって形成され、該突条４’，４”の中程上部の傾倒角度αが中程下部の傾倒角度βよりも若干小であるため、上記支柱５の下部の４方の角部を前後左右に若干拡大し得るばかりでなく、４方の角錐面が上記凹部２の凹弧面４ｃ’と一連の凹弧面４ｃとによりに形成されているため、収納卵がガタ無く収納し得るばかりでなく、隣接卵との間に上記支柱５の突条４’，４”が介在して隣接収納卵相互の間隔を若干拡大させることができる。   In addition, as shown in FIG. 3, four corners of the truncated quadrangular pyramid-shaped support column 5 are formed by vertically extending ridges 4 ′ and 4 ″, respectively, and the middle of the ridges 4 ′ and 4 ″. Since the upper tilt angle α is slightly smaller than the middle lower tilt angle β, the four corners of the lower portion of the support column 5 can be slightly expanded in the front-rear and left-right directions. Since the concave arc surface 4c ′ of the concave portion 2 and the series of concave arc surfaces 4c are formed, not only the stored egg can be stored without play, but also the protrusion 4 of the support column 5 between the adjacent eggs. By interposing ', 4', the interval between adjacent eggs can be slightly expanded.

本発明は、パルプモウルド製の卵の収納用容器として、広く利用が可能である。   The present invention can be widely used as a container for storing eggs made of pulp mold.
