【発明の属する技術分野】
本発明は、複数の鶏卵収容凹部を配列し、且つ、容器本体上に蓋体を折り畳んで包装する構造の合成樹脂製シート素材を、膨出成型させてなる鶏卵容器に関するものである。
【０００２】
【従来の技術】
かかる合成樹脂シート素材を膨出成型させてなる従来の容器の一例として、図１３に示す鶏卵容器の構造について、本発明の容器の実施例と同一の部分は同じ符号を用い、異なる部分には対応する符号にＫを付して説明すると、容器本体１Ｋと蓋体２Ｋとからなり、前記容器本体１Ｋ及び蓋体２Ｋに、鶏卵を収容する複数個の鶏卵収容凹部１３，２３が配列されている。容器本体１Ｋと蓋体２Ｋとの境界部には浅い凹溝状の折り畳み線３が形成され、又、配列された鶏卵収容凹部１３，２３外周部は包装時に容器本体１Ｋと蓋体２Ｋとを重ね合わせて封止するフランジ部１１，２２となっており、該フランジ部１１，２２の前記折り畳み線３の反対側は遊端縁となっている。又、蓋体２Ｋの側壁２２Ｋ並びに天板２４の一部分乃至大部分がラベルを貼付けるための平坦面となっている容器もある。鶏卵包装の概略は、鶏卵の下半分を容器本体１Ｋの鶏卵収容凹部１３に収容し、鶏卵の上半分を覆うように折り畳み線３の部位で折り返して蓋体２Ｋを被せ、容器本体１Ｋのフランジ部１１と蓋体２Ｋのフランジ部２１とを突き合わせて封止してパック包装品する。パック包装品は一定数量を纏めて外装箱に収容されて出荷される。
【０００３】
【発明が解決しようとする課題】
従来のこの種の合成樹脂シート素材を用いた成型容器のうち、蓋体２Ｋの側壁２２Ｋ並びに天板２４がラベルを貼付け用の平坦面となっている容器は、閉蓋時に鶏卵の上半分が収納し得るように、側壁２２Ｋが蓋体２Ｋの鶏卵収容凹部２３のフランジ２１側の側面と等しい角度で立上がり、そのままの傾斜で天板２４と交わるために、他の部位の収容凹部２３の天板２４側の側壁面より突出した稜線Ｌを形成しているので、パック包装品を外装箱に最密状態となるように積み重ねて収容したときに、図１４の側面図に積み重ね状態を示すように、上方となったパック包装品の容器本体１Ｋの底部１４と前記稜線Ｌとが当接して傾斜するため、最密状態で積み重ねて収容できないという欠点があった。又、パック包装品を多数販売する場合にも安定した状態で積み重ねて店頭に出すことができないと言う解決すべき課題を有していた。
【０００４】
そこで、本発明は上記従来例の有する課題を解消し、多数のパック包装品を安定して最密状態で積載保管し得る構造の蓋体を有することで、積載保管時の不祥事を解消し、併せて外装箱のコストダウンを図ることのできる合成樹脂シート製鶏卵容器を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
該目的を達成する手段として講じた本発明の合成樹脂シート製鶏卵容器の構成は、合成樹脂シート素材を膨出成型させて複数個の鶏卵収容凹部１３…を有する容器本体１と鶏卵収容凹部２３…を有する蓋体２とを、その一側縁部分において折り曲げ部３を介して折畳み自在に一連に形成してなる合成樹脂シート製鶏卵容器であって、前記蓋体２のラベル貼付面として使用される少なくとも一つの長手方向の側壁２２が、鶏卵収容凹部２３…の間に位置する二つ以上の谷部が一連に連なった傾斜面に形成され、且つフランジ部２１から天板２４に向かって一連となって形成されている傾斜角度が夫々異なる二つの側壁面２２ａ，２２ｂからなり、当該二つの側壁面２２ａ，２２ｂの境界部で容器の外側に向かって僅かに膨出した形状を有すると共に、前記側壁２２の天板２４側の側壁面２２ａの傾斜角度が、略錐面をなしている前記鶏卵収容凹部１３の底部１４側の側壁面１２ａの傾斜角度と略等しい角度となっていて、閉蓋した状態で上下に積み重ねた場合、上段の容器本体１の２列に並んだ鶏卵収容凹部１３の底部１４は、下段の蓋体２の２列に並んだ鶏卵収容凹部２３の間隙に入り込み、下段の蓋体２の鶏卵収容凹部２３の天板２４に近い側壁面２２ａの外側面は、上段の容器本体１の鶏卵収容凹部１３の底部１４側の側壁面１２ａにほぼ面接触する。
【０００６】
【発明の実施の形態】
本発明を実施するに当たっては、合成樹脂シート素材をブロー成型によって賦形するか、合成樹脂素材を射出成型する。使用する合成樹脂のシート材又は素材は、ＰＥＴ（ポリエチレンテレフタレート樹脂）、ＰＣ（ポリカーボネート樹脂）等周知の素材を使用する。
【０００７】
形状は、外周縁を形成するフランジ部２１の内側に複数の鶏卵収容凹部１３が配置されている容器本体１と、同じく外周縁を形成するフランジ部２１の内側に鶏卵収容凹部２３が配置されている蓋体２とが、夫々の一側縁部分において折り曲げ部３を介して折畳み自在に一連に形成されている。前記鶏卵収容凹部１３は、包装に際して鶏卵の下半分が挿入されるので、側壁１２が傾斜した錐面からなり、この錐面は一般的に鶏卵の外形にほぼ適合させて傾斜角が異なる側壁面１２ａ、１２ｂが連続する形状を成し、通常フランジ部１１、即ち開口側に近い側壁面１２ｂの傾斜角は大きくて傾斜が急峻であり、底部１４側の側壁面１２ａの傾斜角は小さくて、２面の境界部で容器の外方に僅かに膨出した形状の錐面となっている。
【０００８】
蓋体２は、包装時に折り曲げ部３の部位で折り曲げて容器本体１に被せて鶏卵を収容するが、２列に並んだ鶏卵の上半分を覆うための鶏卵収容凹部２３が形成されている。この鶏卵収容凹部２３は鶏卵の上半分を個々に又は包括して覆う空間を形成するが、天板２４の一部分又は大部分と、折り曲げ部３側若しくはフランジ２１の遊端縁側のいずれか一方もしくは両方の長手方向の側壁２２とが、鶏卵収容凹部２３…の間に位置する二つ以上の谷部が一連に連なった平坦面に形成され、平坦面でない部分は容器本体１の鶏卵収容凹部１３と類似形状の錐面からなる。天板２４と側面２２とが境界部の稜線Ｌを介して連続し、開口側に近い側壁面２２ｂの傾斜角は大きくて傾斜が急峻であり，天板２４に近い側の側壁面２２ａの傾斜角度は小さくて、当該二つの側壁面２２ａ，２２ｂの境界部で容器の外側に向かって僅かに膨出した形状となっている。又、側壁面２２ａの傾斜角度は前記鶏卵収容凹部１３の底部１４側の側壁面１２ａの傾斜角度と略等しい角度となっている。鶏卵の包装後にこの平坦面にブランド名や品質を表示するラベル４が貼付けられる。
【０００９】
従って、本発明の鶏卵容器を使用することで、閉蓋した状態で、２個以上のパック包装品を上下に積み重ねた場合、上段の容器本体１の２列に並んだ鶏卵収容凹部１３の底部１４は、下段の蓋体２の２列に並んだ鶏卵収容凹部２３の間隙に入り込み、鶏卵収容凹部２３の天板２４に近い側壁面２２ａの外側面は、上段の容器本体１の鶏卵収容凹部１３の底部１４側の側壁面１２ａにほぼ面接触し、安定した状態で水平状態を維持して店頭で積載した場合でも外装箱の内部でも荷崩れが無く、且つ単純に重ねて積載した場合に比べて、上段の鶏卵収容凹部１３の底部１４が下段の蓋体２の２列に並んだ鶏卵収容凹部２３の間隙に入り込むので、全体の高さは短縮され、従って外装箱内での占有率も良好で外装箱の価格や輸送経費の立場から経済的である。

BACKGROUND OF THE INVENTION
The present invention relates to an egg container in which a plurality of egg-containing recesses are arranged and a synthetic resin sheet material having a structure in which a lid is folded and packaged on a container body is bulged.
[0002]
[Prior art]
As an example of a conventional container formed by bulging and molding such a synthetic resin sheet material, the same reference numerals are used for the same parts as the embodiment of the container of the present invention for the structure of the egg container shown in FIG. The corresponding reference numeral will be described by adding K to the container body 1K and the lid body 2K. The container body 1K and the lid body 2K are provided with a plurality of egg storage recesses 13 and 23 for storing eggs. Yes. A shallow groove-shaped fold line 3 is formed at the boundary between the container body 1K and the lid body 2K, and the outer periphery of the arranged egg receiving recesses 13 and 23 is connected to the container body 1K and the lid body 2K during packaging. The flange portions 11 and 22 are overlapped and sealed, and the opposite side of the fold line 3 of the flange portions 11 and 22 is a free end edge. There is also a container in which a part or most of the side wall 22K of the lid 2K and the top plate 24 are flat surfaces for attaching labels. The outline of the egg packaging is that the lower half of the egg is accommodated in the egg-containing recess 13 of the container main body 1K, folded over at the folding line 3 so as to cover the upper half of the egg, and covered with the lid 2K. The part 11 and the flange part 21 of the lid 2K are butted and sealed to form a pack package. Packed packages are packaged in a package and shipped in a package.
[0003]
[Problems to be solved by the invention]
Among the conventional molded containers using this type of synthetic resin sheet material, the container 22 whose side wall 22K and the top plate 24 of the lid 2K are flat surfaces for labeling is such that the upper half of the egg is closed when the lid is closed. Since the side wall 22K rises at an angle equal to the side face on the flange 21 side of the egg-containing recess 23 of the lid 2K so that it can be stored, and crosses the top plate 24 with the same inclination, the top of the storage recess 23 in another part Since the ridge line L protruding from the side wall surface on the plate 24 side is formed, when the pack package is stacked and accommodated in the outer packaging box so as to be in the most dense state, the stacked state is shown in the side view of FIG. In addition, since the bottom 14 of the container body 1K of the pack package and the ridgeline L which contact the upper side and incline, there is a disadvantage that they cannot be stacked and accommodated in a close-packed state. Further, even when a large number of packed packages are sold, there is a problem to be solved that it is impossible to stack them in a stable state and put them out at the store.
[0004]
Therefore, the present invention solves the problems of the above-described conventional example, and has a cover body that can stably store and pack a large number of packed packages in a close-packed state, thereby eliminating a scandal during loading and storage.

【The invention's effect】
As is clear from the above description, the synthetic resin sheet egg container of the present invention has two side walls in the longitudinal direction of the lid, the inclination angle of the side wall surface near the opening side is large, and the inclination is steep. Yes, the inclination angle of the side wall surface on the side close to the top plate is small, and the shape slightly bulges toward the outside of the container at the boundary between the two side wall surfaces. In addition, the inclination angle of the side wall surface close to the top plate is substantially equal to the inclination angle of the side wall surface on the bottom side of the egg receiving recess of the container body, so that it is stacked inside the storefront or the exterior box. In this case, the bottom of the egg receiving recess in the upper container body enters the gap between the egg receiving recesses arranged in two rows of the lower lid, and the outside of the side wall near the top plate of the egg receiving recess in the lower lid The side surface is substantially in surface contact with the side wall surface on the bottom side of the egg-containing recess of the upper container body, and there is no collapse of the load even in the exterior box even when the container is loaded in the store while maintaining the horizontal state in a stable state. The occupancy rate in the outer box was also good, and it was possible to expect the effect of being economical from the standpoint of the price of the outer box and the transportation cost.
