らなるものである。(Means for Solving the Problems) The technical means of the present invention for solving the above problems are
A hollow partitioning ventilation window is provided on a partitioning partition having a triangular cross section, and a bottoming ventilation window of the same length is formed directly below the ventilation window and communicating with this ventilation partitioning window. A mold is composed of a crate with ventilation windows, a female plate, a male plate, and an intermediate plate, and a synthetic resin is injected into the mold to form a crate with a partition having a triangular cross section. And a male plate is inserted into the slot having a triangular cross section, and a protrusion having a triangular cross section is formed on the female plate to form a hollowed hole in the partition. From a mold for forming a crate with a ventilation window in the middle, characterized in that the body and the male die form a bottom ventilation window hole having the same length in the longitudinal direction that communicates with the window directly below the ventilation hole in the middle partition. It will be.
（発明の効果） 本発明の技術的手段、とくに成形金型によれば、中仕切
のないクレートや中仕切に窓のないクレートと同じ条件
で、強度的に強い中仕切に通風窓をつけたクレートを形
成することができるもので、しかも成型されたクレート
は通風性が良いので冷却の通気性がよく、容器をよく冷
却し、冷却効果が倍増するという特徴がある。(Advantages of the Invention) According to the technical means of the present invention, particularly the molding die, a ventilation window is attached to a strong partition under the same conditions as a crate having no partition or a windowless crate. Crate can be formed, and since the molded crate has good ventilation, it has good air permeability for cooling, cools the container well, and doubles the cooling effect.
又、中抜き仕切の通風窓と底抜き式の通風窓とが縦方向
に同長であれば容易に底抜き式通風窓が成型でき、平面
視形状の変わった底抜き式の通風窓を形成できて、強度
がありながら体裁のよいクレートがえられる。In addition, if the ventilation window with the inner partition and the ventilation window with the bottom have the same length in the vertical direction, the ventilation window with the bottom can be easily molded, and the ventilation window with the bottom shape with a different plan view is formed. The result is a strong, well-formed crate.
（実施例） 以下、図面に示す実施例について説明する。(Example) Hereinafter, the Example shown in drawing is described.
先ず、クレートの構造から説明すると、第１図に示すも
のは中仕切のないクレート（１）を示しており、周壁
（２）に通風窓（３）がある。First, the structure of the crate will be described. FIG. 1 shows the crate (1) having no partition, and the peripheral wall (2) has a ventilation window (3).
第２図に示すものは、中仕切（４）のあるクレート
（１）を示している。中仕切のないクレートは勿論のこ
と、中仕切に通風窓のないクレートを使用するとクレー
ト内の通気が遮断されて冷却の通気性が悪くなり、容器
を冷却する効果が減少する。The one shown in FIG. 2 shows a crate (1) having a partition (4). When using a crate having no ventilation window as well as a crate having no partition, the ventilation in the crate is blocked and the ventilation of cooling is deteriorated, so that the effect of cooling the container is reduced.
とくに、クレートを積み上げて使用する時に顕著に現れ
る。In particular, it appears remarkably when the crates are stacked and used.
そこで、中仕切（４）に第３図に示すような中抜き式の
通風窓（５）をつけたクレートの成型が望まれるが、後
述するようにその成型方法や成型金型が複雑化し、成型
時間や成型コストを多く必要とする。Therefore, it is desired to mold the crate with the hollow type ventilation window (5) as shown in FIG. 3 in the partition (4), but as will be described later, the molding method and molding die are complicated, It requires a lot of molding time and cost.
そこで、第４図に示すような中抜き窓（５）すなわち通
風窓を中仕切（４）に設けるとともに、底抜き窓（６）
を中抜き窓（５）の真下に設けたクレートを成型する
と、中仕切通風窓の中抜き式と同じ通気性の効果を得な
がら成型方法や成型金型が単純化し、成型時間や成型コ
ストを少なくすることができる。Therefore, as shown in FIG. 4, a hollow window (5), that is, a ventilation window is provided in the partition (4), and the bottom window (6) is provided.
Molding the crate directly below the hollow window (5) simplifies the molding method and mold while achieving the same air permeability effect as the hollow type of the partitioning ventilation window, reducing molding time and molding cost. Can be reduced.
そして底抜き式通気窓（６）のある中仕切（４）は、ク
レート底部（８）における接合部（７）の強度を上げる
ために、中仕切の横断面が第10図に示すように三角形状
とすると、中仕切本体と接合部（７）を補強することが
できる。Then, in order to increase the strength of the joint part (7) in the crate bottom (8), the cross section (4) with the bottomed vent window (6) has a triangular cross section as shown in FIG. With the shape, the partition body and the joint part (7) can be reinforced.
次に、成型金型について説明すると、第５図は中仕切の
ない第１図に示すクレートの成型金型断面を示すもので
あって、雄型プレート（９）と雌型プレート（10）及び
中間プレート（11）（12）とで型孔をつくり、これに合
成樹脂を射出して成型するものである。矢印は型開きの
金型プレートの移動方向を示す。Next, the molding die will be described. FIG. 5 is a cross-sectional view of the molding die of the crate shown in FIG. 1 having no partition, which includes a male plate (9), a female plate (10), and A mold hole is formed with the intermediate plates (11) and (12), and a synthetic resin is injected into this to mold. The arrow indicates the moving direction of the mold plate for opening the mold.
第６図のものは、第２図に示す中仕切窓のないクレート
の成型を示すもので、中仕切形成のための溝孔（13）が
雄型プレート（９）に形成してある。他は第５図のもの
と同様である。FIG. 6 shows the molding of the crate shown in FIG. 2 without the partition wall, and the slot (13) for forming the partition is formed in the male plate (9). Others are the same as those in FIG.
第７図に示すものは、中仕切中抜き式窓付きクレートの
成型金型を示すもので、中抜き窓（５）を形成するため
の中子（14）が必要となり、成型が複雑化する。The one shown in FIG. 7 shows a molding die for a crate with a partitioning and hollowing type window, which requires a core (14) for forming the hollowing window (5), which complicates molding. .
そこで本発明では、第８図に示すように中仕切中抜き窓
孔（５）を形成すると共に、この真下に、これと連通す
る縦方向に同長の中仕切底抜き窓孔（６）を形成できる
金型を創案した。Therefore, in the present invention, as shown in FIG. 8, an intermediate partition hole (5) is formed, and, just below this, a partition hole hole (6) having the same length in the longitudinal direction communicating with this is formed. I created a mold that can be formed.
すなわち、雄型プレート（９）に横断面形状が三角形状
の溝孔（13）を設け、この溝孔（13）中に挿入される横
断面形状が三角形状の突起体（15）を雌型プレート（1
0）に設けたのである。That is, the male plate (9) is provided with a slot (13) having a triangular cross-section, and the protrusion (15) having a triangular cross-section inserted into the slot (13) is inserted into the female die. Plate (1
It was installed in 0).
かかる金型を用いると、型開き時雄型プレート（９）と
雌型プレート（10）とが容易に矢印方向に分離でき、中
仕切底抜き窓付きクレートが成型できる。When such a mold is used, the male plate (9) and the female plate (10) can be easily separated in the direction of the arrow when the mold is opened, and the crate with the window for removing the middle partition bottom can be molded.
本発明によれば、冷却の通風窓として必要な大きさの突
起体（15）を設けることによって、中仕切に通風窓の付
いたクレート（第４図）を簡単な方法で成型ができる。According to the present invention, by providing the projection (15) having a size necessary for a ventilation window for cooling, it is possible to mold the crate (FIG. 4) having the ventilation window on the partition by a simple method.
なお、底抜き窓は第９図の他、第10図に示すような形状
でも良く、本発明における効果は容易に得られるもので
ある。The bottom window may have a shape as shown in FIG. 10 in addition to that shown in FIG. 9, and the effect of the present invention can be easily obtained.
また、本発明のような中仕切底抜き通風窓付きクレート
の材質は、成型性、剛性等からポリエチレン、又はポリ
プロピレンが用いられる。Further, as the material of the crate with a ventilation window without a partition bottom as in the present invention, polyethylene or polypropylene is used because of its moldability and rigidity.
