【考案が解決しようとする課題】[Problem that the idea aims to solve]

上記のようにして密封する従来の容器は、蓋の周溝を形成する逆Ｕ字形の下縁を外向き開くと密封が開放され、それによって蓋の着脱が容易になる一方で、周溝の弾性劣化から意外と早い時期に密封性が低下するという欠点がある。また、容器内の収容物の膨張とか、容器内に密封された空気等の気体の膨張、収縮によっても周溝が開いて密封性が失われ、不用意に内容物がもれ出るおそれもある。 Conventional containers that are sealed as described above have an inverted U-shaped lower edge that forms the circumferential groove of the lid. Opening outward releases the seal, which facilitates the removal and installation of the lid, while also The drawback is that the sealing performance deteriorates sooner than expected due to elastic deterioration of the groove. In addition, expansion of the contents inside the container, expansion of gas such as air sealed inside the container, Due to shrinkage, the circumferential groove may open and the sealing performance may be lost, causing the contents to leak out inadvertently. There is also.

【０００４】そのために、容器本体と蓋とのみからなる簡易性と、蓋の着脱が容易であるというこの種の容器の利点を損なわずに、密封性の向上とその維持を図ることが課題となっていた。0004 For this reason, we need a simple structure consisting of only a container body and a lid, and the lid can be easily attached and removed. The challenge is to improve and maintain sealing performance without sacrificing the advantages of this type of container. It was a topic.

【課題を解決するための手段】[Means to solve the problem]

そこで本考案は、容器本体と、容器本体の縁に弾性的に密着する断面逆Ｕ字形の周溝を周縁部に具えた蓋とを合成樹脂で成形して着脱自在に密封するようにした簡易形の密封容器において、前記蓋の周溝の外側の下縁に、適宜の幅で水平方向に張り出して該周溝の下縁の膨出を阻止するようにした鍔部を全周に連続して一体成形したことを特徴とする簡易形密封容器を提供するものである。 Therefore, the present invention consists of a container body and an inverted U-shaped cross section that elastically adheres to the edge of the container body. A lid with a circumferential groove on the periphery is molded from synthetic resin and is removably sealed. In a simple sealed container, a horizontal line with an appropriate width is placed on the lower edge of the outside of the circumferential groove of the lid. A flange that protrudes in the opposite direction and prevents the lower edge of the circumferential groove from bulging out continuously around the entire circumference. The present invention provides a simple sealed container characterized by being integrally molded.

【作用】[Effect]

上記のようにして蓋の周溝の外側の下縁に鍔部を全周に連続して一体成形した本考案容器は、逆Ｕ字形の周溝の下縁の拡開がその外側に適宜の幅で水平方向に張り出している鍔部によって、枠を嵌めたように阻止されるので密封性の保持が強固にできる。 As described above, the flange was integrally molded continuously around the entire circumference of the outer lower edge of the circumferential groove of the lid. In the container of this invention, the lower edge of the inverted U-shaped circumferential groove expands horizontally to the outside with an appropriate width. The overhanging flange blocks the frame as if it were fitted into a frame, so it maintains a tight seal. It can be made strong.

【０００７】また、上記鍔部の形成を蓋と一体成形しているので、この種の容器の簡易性を損なわず、また、上記鍔部によって周溝の下縁の拡開は水平方向に抑止が働くが、上下方向の弾性にはさほどに影響しない。したがって、蓋の着脱が容易であるというこの種の容器の利点も損なわれていない。[0007] In addition, since the flange is formed integrally with the lid, this type of container is simple. In addition, the flange prevents the lower edge of the circumferential groove from expanding in the horizontal direction. , it does not significantly affect the elasticity in the vertical direction. Therefore, it is easy to attach and detach the lid. The advantages of this type of container are still intact.

【実施例】【Example】

以下に本考案の実施例を図面について説明する。図において、１は四隅と底部の四辺に丸みを設けて長立方形に成形した容器本体、２は多少膨出する上部を有する容器本体１の縁、３は容器本体１の縁２に弾性的に密着する断面逆Ｕ字形の周溝４を周縁部に具えて長方形に成形した蓋、５は周溝４の下縁外側に適宜の幅で水平方向に張り出している鍔部である。この鍔部５は蓋３と肉厚をほぼ等しくして周溝４の外側に全周に連続して一体成形されている。 Embodiments of the present invention will be described below with reference to the drawings. In the figure, 1 is a container book shaped into a long cube with rounded corners and four sides of the bottom. body, 2 is an edge of the container body 1 having a slightly bulging upper part, 3 is an elastic body on the edge 2 of the container body 1; A lid formed into a rectangle with a circumferential groove 4 having an inverted U-shaped cross section for sexual contact on the periphery, 5 is a flange projecting horizontally to the outside of the lower edge of the circumferential groove 4 with an appropriate width. This tsuba The portion 5 is integrally molded continuously around the entire circumference outside the circumferential groove 4 so as to have approximately the same wall thickness as the lid 3. ing.

【０００９】図１に示すように分離している蓋３を図２に示すように容器本体１に被せると、断面逆Ｕ字形の周溝４が容器本体１の縁２に弾性的に密着嵌合し、容器は密封状態になる。そして、周溝４は外側に枠を嵌められたように鍔部５によって緊締され、下縁の外開きを強固に抑止される。[0009] When the separate lid 3 as shown in Figure 1 is placed over the container body 1 as shown in Figure 2, , the circumferential groove 4 having an inverted U-shaped cross section is elastically tightly fitted to the edge 2 of the container body 1, and the container is sealed. become a state. Then, the circumferential groove 4 is tightened by the flange 5 as if a frame was fitted on the outside. This strongly prevents the lower edge from opening outward.

【００１０】また蓋３を外す時は、例えば下から指を掛けて鍔部５を持ち上げるように操作すれば、鍔部５は周溝４とともに比較的容易に撓んで、縁２から蓋３を外すことができる。0010 Also, when removing the lid 3, for example, put your finger on it from below and lift the flange 5. Then, the flange 5 can be bent relatively easily together with the circumferential groove 4, and the lid 3 can be removed from the edge 2. I can do it.

【考案の効果】[Effect of the idea]

前記のように、断面逆Ｕ字形の周溝の下縁外側に全周に連続して一体成形した鍔部を設けて該周溝の拡開を防止するようにした本考案密封容器によれば、この種の容器が持つ簡易性と着脱のし易さを損なうことなく、強固な密封状態を永く維持することができ、安心して容器を使用できるという実用的効果が期待できる。 As mentioned above, a continuous piece is molded around the entire circumference on the outside of the lower edge of the circumferential groove with an inverted U-shaped cross section. According to the sealed container of the present invention, which is provided with a flange to prevent the circumferential groove from expanding, Maintains a strong seal for a long time without sacrificing the simplicity and ease of putting on and taking off seed containers. It can be expected to have the practical effect of allowing containers to be maintained and used with peace of mind. .
