りも全体的に大きくしている。(Embodiment) As shown in FIG. 1, a heat-insulating container according to a first embodiment of the present invention includes a container body 1 made of foamed synthetic resin such as foamed polystyrene, and a foamed container that closes the upper opening of the container body 1. As shown in FIG. 3, an annular engagement groove 3 is formed in the outer peripheral edge 1a of the opening of the container body 1, and the arc-shaped opening 3a of the engagement groove 3 is The width l 1 is smaller than the width l 2 of the maximum groove width portion 3b 1 of the circular depth portion 3b (l 1 < l 2 ), and correspondingly, the outer peripheral edge 2a of the lower surface of the lid body 2 is formed.
An annular engagement protrusion 4 that fits into the engagement groove 3 is formed, and the tip 4a of the engagement protrusion 4 is circular, and the width L 1 of the thickest portion 4a 1 of the tip 4a is shaped like an arc. larger than the width L 2 of the root portion 4b (L 1 <L 2 )
Furthermore, the thickness of the engaging protrusion 4 is made larger than the groove width of the engaging groove 3 so that the engaging groove 3 is slightly expanded when the engaging protrusion 4 is fitted into the engaging groove 3. is also larger overall.

る。 Therefore, from the state shown in FIG.
When the engagement protrusion 4 is pushed into the engagement groove 3, the tip 4a of the engagement protrusion 4 pushes apart the opening 3a of the engagement groove 3 and enters the deep part 3b, as shown in the virtual line state in FIG. The engagement groove 3 is pushed out as shown by the solid line in the figure, and the inner surface of the engagement groove 3 comes into close contact with the engagement protrusion 4.

とができる。 Therefore, the depth h 1 from the opening end surface 3a 1 of the engagement groove 3 to the engagement receiving surface 3c of the depth portion 3b is the same as the depth h 1 from the root end surface 4b 1 of the engagement protrusion 4 to the engagement surface 4c of the tip portion 4a.
In other words, it is formed to be deeper than the height h 2 of the up to As a result, the engagement surface 4c of the engagement protrusion 4 comes into pressure contact with the engagement receiving surface 3c of the engagement groove 3, which acts to forcefully pull the engagement protrusion 4 into the depth side of the engagement groove 3, and this retraction force Engagement protrusion 4
Root end surface 4b 1 , that is, the lower outer peripheral edge 2a of the lid body 2
is strongly brought into close contact with the opening end surface 3a 1 of the engagement groove 3, that is, the outer peripheral edge 1a of the container body 1, and the airtight effect can be improved.

すことができる。 Furthermore, when the engaging protrusion 4 is fitted into the engaging groove 3, it can be fitted smoothly due to the contraction effect peculiar to the foamed synthetic resin, and the wall thickness of the engaging protrusion 4 can be adjusted to fit the engaging groove 3. Since the entire engagement surface of the engagement protrusion 4 is formed larger than the groove width, the entire engagement surface of the engagement protrusion 4 is formed in the engagement groove 3.
The entire engagement receiving surface is always in pressure contact, and this surface can also improve the airtight effect. In FIG. 1, reference numeral 5 indicates a grip portion formed on both sides of the container body 1, and reference numeral 15 indicates a recess for inserting a fingertip formed at the outer peripheral edge 1a of the opening of the container body 1. When taking out the container, the lid 2 can be removed from the container body 1 by inserting a fingertip into the recess 15 and pulling the lid 2 slightly upwardly from the container body 1.

（考案の効果）
本考案によれば、次のような特有の効果を有す
る。(Effects of the invention) The invention has the following unique effects.
発泡合成樹脂特有の弾性伸縮力により蓋体に
突設した係合突起は、容器本体に穿設された係
合溝に容易に係合すると共に、その係合状態を
強固に維持することができる。 Due to the elastic expansion and contraction force unique to foamed synthetic resin, the engagement protrusion protruding from the lid can easily engage the engagement groove drilled in the container body, and can firmly maintain the engaged state. .
蓋体に突設した係合突起の肉厚は、容器本体
に突設された係合溝の溝幅よりも全体的に大に
形成してなるため、発泡合成樹脂特有の弾性伸
縮力と相俟つて係合突起の係合面が係合溝の係
合受面に全面的に強力に密接し、確実に気密効
果を上げることができる。 The thickness of the engagement protrusion protruding from the lid body is larger overall than the width of the engagement groove protruding from the container body, so it is compatible with the elastic expansion and contraction force unique to foamed synthetic resin. As a result, the engagement surface of the engagement protrusion comes into strong contact with the engagement receiving surface of the engagement groove over the entire surface, and the airtight effect can be reliably improved.
係合突起を係合溝に係嵌した際に係合突起を
係合溝の奥行側に強力に引込む作用が働き、こ
の引込み力によつて蓋体と容器本体の互の吻合
面が強力に密接し、この面からも一層の気密効
果を上げることができる。 When the engaging protrusion is fitted into the engaging groove, the engaging protrusion is strongly pulled into the depth of the engaging groove, and this pulling force causes the anastomotic surfaces of the lid body and the container body to become strong. They are in close contact with each other, and from this aspect as well, the airtight effect can be further improved.
従来のように粘着テープや締結紐などを用い
て蓋体を容器本体に固定する必要がないから材
料費の軽減をもたらすことができ、しかも外観
上の体裁も良好である。 Since there is no need to fix the lid to the container body using adhesive tape or fastening strings as in the past, material costs can be reduced, and the appearance is also good.

(2) A cut is made on the top surface of the tip of the engagement protrusion,
A container as set forth in claim 1, in which the tip is made contractible. (3) A container as set forth in claim 1, in which a notch is made in the top surface of the tip of the engaging projection and a protrusion is formed on the bottom surface of the depth of the engaging groove to engage with the notch and prevent the notch from narrowing. (4) A container as set forth in claim 1, in which the tip of the engaging projection and the depth of the engaging groove are formed into an approximately polygonal shape.
