Are deep on the outer surface side 11A of the wrapping tool 10 and shallow on the inner surface side 11B. Has been formed. Further, a circular protrusion 12 is formed in a raised shape with a height of about 3 mm on the bottom surface inside the packaging tool.
この果実用包装具１０の製造方法を以下に述べる。A method of manufacturing the fruit packaging device 10 will be described below.
まず、第３図および第４図に図示した真空成形型２０を
用意する。First, the vacuum molding die 20 shown in FIGS. 3 and 4 is prepared.

すそ広がり部２１Ｓを有している。The vacuum forming die 20 has a substantially hemispherical shape, and a circular protrusion 22 is provided on the zenith portion so as to have a height of several mm. A large number of radial ribs 2 are provided downward from the protrusion 22.
1, 21 ... Are formed, and have a smooth splayed portion 21S near the lower end thereof.
図において符号２３，２３は真空吸引するための吸引孔
であって、真空成形の公知の手法によって真空装置に連
通される。In the figure, reference numerals 23 and 23 are suction holes for vacuum suction, which are communicated with a vacuum device by a known method of vacuum forming.
第５図の（Ａ）、（Ｂ）に図示するように、この真空成
形型２０の上に、予め１２０度もしくは１３０度に予備
加熱された発泡合成樹脂シート材、例えば厚さ５mmの発
泡ポリエチレンシート３０を配置し、押さえ治具２４で
押さえた後、真空成形を行う。As shown in FIGS. 5 (A) and 5 (B), a foam synthetic resin sheet material preheated to 120 ° or 130 ° on the vacuum molding die 20, for example, a polyethylene foam having a thickness of 5 mm. After the sheet 30 is placed and pressed by the pressing jig 24, vacuum forming is performed.
成形後、賦形されたポリエチレンシート３０ａを同図
（Ｂ）の破線Ｐで示した位置で円形に切除してから取り
出し、同図（Ｃ）で示すような個別の所定半球状の成形
品３１を得る。図中符号３２は成形品内面、３３は同外
面、３６は切り口である。After molding, the shaped polyethylene sheet 30a is cut out into a circle at the position shown by the broken line P in FIG. 3B and then taken out, and the individual predetermined hemispherical molded product 31 as shown in FIG. To get In the figure, reference numeral 32 is an inner surface of the molded product, 33 is an outer surface thereof, and 36 is a cut end.
次いで、この別個の成形品３１を裏返して第１図に図示
した製品１０とする。Then, this separate molded product 31 is turned over to obtain the product 10 shown in FIG.
この製造方法から理解されるように、発泡合成樹脂シー

だけ浅く（弱く）なる。As can be understood from this manufacturing method, the inner surface side 32 where the foamed synthetic resin sheet material 30 is in direct contact with the mold surface of the molding die 20 is turned over to the outside of the product 10 by turning the molded product 31 over to form the outer surface side rib 11A. Form. On the other hand, the outer surface 33 on the pressing jig side of the sheet 30 is on the inner side of the product and forms the inner surface side rib 11B. As a result, the rib 11A on the outer surface side of the product is deep (strong) because it is a portion that is in direct contact with the mold surface of the molding die 20, and the rib 11B on the inner surface side is shallow (weak) by the thickness of the sheet.
また、裏返し前に外側を向いていたすそ広がり部３４は
裏返すことによって内側を向くので、開口部内径が包装
具本体の大径部より小さく形成される。また凹部３５は
裏返しによって製品底部に持ち上げ状の突部１２を形成
する。Further, since the skirt expanding portion 34 that has faced the outside before turning over faces the inside by turning over, the inside diameter of the opening is formed smaller than the large diameter part of the packaging body. The concave portion 35 is turned upside down to form a raised protrusion 12 on the bottom of the product.
さらに切り口３６は内側を向くのでみばえがよくなり、
包装具の外観性はいっそう向上する。Furthermore, since the cut 36 faces inward, the appearance is improved,
The appearance of the packaging is further improved.
（効果） 以下図示し説明したように、この発明によって得られる
発泡合成樹脂製包装具は、外側のリブが深く、内側のリ

大きくなる。Moreover, since the inner diameter of the opening is formed smaller than the large diameter portion of the body of the packaging tool, the holding property and the wrapping property of the fruits are improved, and the cold insulation effect by the heat insulating layer can be further enhanced. At the same time, the tolerance for the size of the packaged object such as fruits is increased.
さらに内部底面に設けられた持ち上げ状の突部によって
被包装物底面は底板等と直接接触することなく緩衝的に
保持されることができる。In addition, the bottom surface of the article to be packaged can be held in a cushioned manner without directly contacting the bottom plate or the like by the raised protrusion provided on the inner bottom surface.
