Further, the outermost dimension A of the flange portion 11 is formed shorter than the outermost dimension B of the step portion 10 and longer than the inner dimension C of the step portion 10 which is substantially the same as the thickness of the outer container body 2. (C <A <B). In the present embodiment, the outermost dimension of the protruding piece 16 is formed to be approximately the same as the outermost dimension A of the flange portion 11.

そして、外容器本体２内に内容器本体３を収納する際には、外容器本体２の係止受部９に対応する内容器本体３の係止部13を位置合わせし、内容器本体３を上方より外容器本体２内に挿入することで、外容器本体２の係止受部９に内容器本体３の係止部13が係止され、これと同時に内容器本体３におけるフランジ部11の底面17が外容器本体２における段差部10の上面18に当接して懸架配置されることで一体となり二重容器19を形成する。この時、内容器本体３の外側面に取り付けられた閉塞部材15は、突状片16が外容器本体２の内側面に接触して弾性変形するため、外容器本体２と内容器本体３との間隙を閉塞することができ、外容器本体２内に入れた内容物が外部に漏れることを確実に防止することができる。   When the inner container body 3 is stored in the outer container body 2, the locking portion 13 of the inner container body 3 corresponding to the locking receiving portion 9 of the outer container body 2 is aligned, and the inner container body 3 is positioned. Is inserted into the outer container body 2 from above, so that the locking portion 13 of the inner container body 3 is locked to the locking receiving portion 9 of the outer container body 2, and at the same time, the flange portion 11 of the inner container body 3 is locked. The bottom surface 17 is in contact with the top surface 18 of the stepped portion 10 in the outer container body 2 and is suspended so as to be integrated to form a double container 19. At this time, the closing member 15 attached to the outer surface of the inner container body 3 is elastically deformed by the protruding piece 16 coming into contact with the inner surface of the outer container body 2, so that the outer container body 2, the inner container body 3, It is possible to close the gap between the outer container body 2 and the contents contained in the outer container body 2 to be reliably prevented from leaking to the outside.

こうして一体となった二重容器19の上方には、蓋４が装着される。蓋４は、外容器本体２における第一の口元部６の外寸法と略同寸であって、上面の左右方向における一端から他端にかけて凹状に連続するベルト溝20が設けられる天板部21と、該天板部21の下面より下方に突設し、内容器本体３の内寸法よりも僅かに短い胴部22と、該胴部22の外側面に周設される嵌合溝23とを備えている。嵌合溝23には、シリコンゴム、エラストマー樹脂等の弾性材料からなる弾性パッキン24が嵌合され、弾性パッキン24の最外寸法Ｄは、フランジ部11の最外寸法Ａ以上で、且つ段差部10の最外寸法Ｂ以下（Ａ≦Ｄ≦Ｂ）であることにより、二重容器19の上方に蓋４を装着する場合には、内容器本体３のフランジ部11の上面25に弾性パッキン24の下面26が当接して内容器本体３内を密閉状態とすることができる。また、内容器本体３を除いた場合であっても、内容器本体３のフランジ部11と同様に、弾性パッキン24の下面26が外容器本体２における段差部10の上面18に当接して懸架配置され、外容器本体２内を密閉することができるので、用途に合せて複数の組み合わせを実施することができる。 The lid 4 is mounted above the double container 19 integrated in this way. The lid 4 is substantially the same as the outer dimension of the first mouth part 6 in the outer container body 2, and the top plate part 21 is provided with a belt groove 20 that is concavely continuous from one end to the other end in the left-right direction of the upper surface. A body portion 22 projecting downward from the lower surface of the top plate portion 21 and slightly shorter than the inner dimension of the inner container body 3, and a fitting groove 23 provided around the outer surface of the body portion 22. It has. An elastic packing 24 made of an elastic material such as silicon rubber or elastomer resin is fitted into the fitting groove 23, and the outermost dimension D of the elastic packing 24 is equal to or larger than the outermost dimension A of the flange portion 11 and a stepped portion. by being outermost dimension B hereinafter of 10 (a ≦ D ≦ B) , when mounting the lid 4 is above the double container 19, the elastic gasket on the upper surface 25 of the flange portion 11 of the inner container body 3 The inner surface of the inner container body 3 can be sealed by the contact of the lower surface 26 of 24. Even when the inner container body 3 is omitted, the lower surface 26 of the elastic packing 24 is in contact with the upper surface 18 of the step portion 10 in the outer container body 2 in the same manner as the flange portion 11 of the inner container body 3. Since it is arrange | positioned and the inside of the outer container main body 2 can be sealed, several combinations can be implemented according to a use.

蓋４の嵌合溝23に嵌合する弾性パッキン24は、水平軸の下方側に折り返された折り返し部27を有しているので、上下方向に高くなり折り返し部27の内側に空隙Ｋが形成される。しかも、折り返し部27の高さＴ１は、段差部10の高さＴ２よりも高く設定されているため（Ｔ２＜Ｔ１）内容器本体３を除いて外容器本体２の段差部10に蓋４を装着する際には、弾性パッキン24が有する折り返し部27の空隙Ｋにより、上下方向の変形が確保されるので、上方より力を加えられると弾性パッキン24が弾性変形して段差部10との間隙をなくし、段差部10と当接することができ、止水性や密閉性の高い嵌合状態とすることができる。   The elastic packing 24 fitted in the fitting groove 23 of the lid 4 has a folded portion 27 that is folded back to the lower side of the horizontal axis, so that it rises in the vertical direction and a gap K is formed inside the folded portion 27. Is done. Moreover, since the height T1 of the folded portion 27 is set to be higher than the height T2 of the step portion 10 (T2 <T1), the lid 4 is attached to the step portion 10 of the outer container body 2 except for the inner container body 3. When mounting, since the deformation in the vertical direction is secured by the gap K of the folded portion 27 of the elastic packing 24, the elastic packing 24 is elastically deformed when a force is applied from above, so that the gap between the stepped portion 10 and the elastic packing 24 And can be brought into contact with the stepped portion 10 to achieve a fitting state with a high water-tightness and airtightness.

そして、二重容器19又は外容器本体２の上方に蓋４を配置した後には、蓋４と外容器本体２をベルト５によって締め付けて固定する。ベルト５は、シリコンゴム、エラストマー樹脂等の弾性材料で帯状に形成され、長手方向における一側の中間部と他側の中間部にそれぞれ取付孔28，28´を設けている。取付孔28は、ベルト５の長手方向を縦方向とした場合に横長矩形状をなし、取付孔28の横寸法は、取付孔28が掛け止められる外容器本体２の掛止部７が有する矩形状の突起７Ａの横寸法と略同寸であるが、取付孔28の縦寸法は、外容器本体２の掛止部７が有する矩形状の突起７Ａの縦寸法よりも短く形成されている。また、一側の取付孔28から他側の取付孔28´までの長さは、一側の掛止部７から他側の掛止部７´までの長さよりも短く形成される。   And after arrange | positioning the lid | cover 4 above the double container 19 or the outer container main body 2, the lid | cover 4 and the outer container main body 2 are fastened and fixed with the belt 5. FIG. The belt 5 is formed in a band shape from an elastic material such as silicon rubber or elastomer resin, and has attachment holes 28 and 28 'in the intermediate portion on one side and the intermediate portion on the other side in the longitudinal direction. The mounting hole 28 has a horizontally long rectangular shape when the longitudinal direction of the belt 5 is the vertical direction, and the horizontal dimension of the mounting hole 28 is a rectangular shape of the latching portion 7 of the outer container body 2 to which the mounting hole 28 is latched. The vertical dimension of the mounting hole 28 is shorter than the vertical dimension of the rectangular protrusion 7A of the latching portion 7 of the outer container body 2 although it is substantially the same as the horizontal dimension of the shape protrusion 7A. Further, the length from the one side mounting hole 28 to the other side mounting hole 28 ′ is shorter than the length from one side hooking portion 7 to the other side hooking portion 7 ′.

こうした構成のベルト５により、蓋４と外容器本体２を締め付けて固定する際には、位置ずれ防止用のベルト溝20を通して配置したベルト５の一側の取付孔28を、対応する一側の掛止部７における突起７Ａの下端に引掛けて、他側に掛け渡す。ベルト５は、弾性材料からなるため性質上弾性変形、すなわち伸張自在であることから、寸法上の長さが足りなくとも、取付孔28内に掛止部７,７´が有する矩形状の突起７Ａ,７Ａ´を挿通させることや、外容器本体２における一側の掛止部７から他側の掛止部７´まで掛け渡すことができると共に、蓋４の弾性パッキン24を内容器本体３のフランジ部11の上面25又は外容器本体２の段差部10の上面18に確実に当接させて締め付けるように固定することができ、密閉性を確保することができる。   When the lid 5 and the outer container body 2 are fastened and fixed by the belt 5 having such a configuration, the mounting hole 28 on one side of the belt 5 disposed through the belt groove 20 for preventing misalignment is provided on the corresponding one side. It hooks on the lower end of the protrusion 7A in the hooking portion 7 and is hung on the other side. Since the belt 5 is made of an elastic material, the belt 5 is elastically deformable, that is, is freely stretchable. Therefore, even if the length of the belt 5 is not sufficient, the rectangular projections of the latching portions 7 and 7 ′ in the mounting hole 28 are provided. 7A and 7A 'can be inserted, and the outer container body 2 can be hooked from one side hooking part 7 to the other side hooking part 7', and the elastic packing 24 of the lid 4 is attached to the inner container main body 3 The upper surface 25 of the flange portion 11 or the upper surface 18 of the stepped portion 10 of the outer container main body 2 can be securely abutted and fixed so as to be secured.

しかも、容器内に内容物を入れて電子レンジ等を用いて加熱する際には、内圧上昇に伴い蓋４に非密着状態となる方向、すなわち上方向に力が加わるが、こうした場合にあっても本実施例では内圧上昇に対応してベルト５が伸張するため、蓋４と容器の間から空気が抜けて非加圧状態とすることができる。さらに、蓋４を容器から外す際には、掛け止められている取付孔28，28´を解放するだけでよいため、使用者による着脱が容易となる。   Moreover, when the contents are put in the container and heated using a microwave oven or the like, a force is applied in a direction in which the lid 4 is not in close contact with the increase in internal pressure, that is, in an upward direction. However, in this embodiment, the belt 5 expands in response to the increase in internal pressure, so that air can escape from between the lid 4 and the container so that the non-pressurized state can be obtained. Furthermore, when removing the lid 4 from the container, it is only necessary to release the mounting holes 28 and 28 'that are latched, so that the user can easily attach and detach.

以上のように、本実施例では、第一の口元部６に段差部10を有した外容器本体２と、前記段差部10に懸架配置されるフランジ部11を第二の口元部12に有した内容器本体３と、弾性パッキン24を嵌合する蓋４と、蓋４と外容器本体２を締め付けるベルト５から構成され、第二の口元部12のフランジ部11の上面25と弾性パッキン24は当接し、かつ内容器本体３を除去した段差部10に対しても上面18に弾性パッキン24が当接することで、内容器本体３、外容器本体２それぞれに使用できる共通の蓋４により部品数を削減し、かつ密閉性の高い弾性パッキン24を蓋４に配置することにより止水性の高い容器の組み合わせを実施することができる。   As described above, in the present embodiment, the second mouth portion 12 has the outer container body 2 having the step portion 10 in the first mouth portion 6 and the flange portion 11 suspended from the step portion 10. The inner container body 3, the lid 4 for fitting the elastic packing 24, the belt 5 for fastening the lid 4 and the outer container body 2, and the upper surface 25 of the flange portion 11 of the second mouth portion 12 and the elastic packing 24. Is in contact with the stepped portion 10 from which the inner container body 3 has been removed, and the elastic packing 24 abuts on the upper surface 18 so that the parts can be used by the common lid 4 that can be used for the inner container body 3 and the outer container body 2 respectively. By combining the elastic packing 24 having a high sealing performance with a reduced number, the combination of containers having a high water-stopping property can be implemented.

また、弾性パッキン24の最外寸法Ｄは、フランジ部11の最外寸法Ａ以上で、段差部10の最外寸法Ｂ以下となることで、内容器本体３を除去した場合には、段差部10上に前記弾性パッキン24が配置され、外容器本体２と当接させることができる。 Further, the outermost diameter D of the elastic packing 24 is above the outermost dimension A of the flange portion 11, by the outermost dimension B hereinafter of the step portion 10, when removing the inner container body 3, step The elastic packing 24 is disposed on the portion 10 and can be brought into contact with the outer container body 2.

また、弾性パッキン24における折り返し部27の上下方向の高さＴ１は、段差部10の高さＴ２より高いことで、弾性パッキン24における上下方向の高さＴ１は、外容器本体２における第一の口元部６の段差部10の高さＴ２より高く設定されるため、弾性パッキン24が嵌められた蓋４を段差部10に配置した時に、弾性パッキン24の上下方向の変形が確保され当接し、密閉性の高い嵌合を実現することができる。   Further, the vertical height T1 of the folded portion 27 in the elastic packing 24 is higher than the height T2 of the stepped portion 10, so that the vertical height T1 of the elastic packing 24 is the first height in the outer container body 2. Since the height 6 is set to be higher than the height T2 of the step portion 10 of the mouth portion 6, when the lid 4 fitted with the elastic packing 24 is disposed on the step portion 10, the elastic packing 24 is deformed in the vertical direction and abuts. It is possible to realize a fitting with high sealing performance.

さらに、外容器本体２と蓋４を締め付けるベルト５が弾性体であることで、弾性体より成るベルト５により着脱が容易となり、容器内の加圧状態の時には、ベルト５が伸びて蓋４が非密着状態の方向に動くことができ、非加圧状態とすることができるので、蓋４が飛んだり外れることがなくなる。   Further, since the belt 5 for tightening the outer container body 2 and the lid 4 is an elastic body, the belt 5 made of an elastic body can be easily attached and detached. When the container is in a pressurized state, the belt 5 extends and the lid 4 Since it can move in the non-contact state and can be in a non-pressurized state, the lid 4 will not fly off or come off.

しかも、内容器本体３の外側面に閉塞部材15を設けたことで、内容器本体３と外容器本体２の密閉性を確保することができる。   In addition, since the closing member 15 is provided on the outer surface of the inner container body 3, the hermeticity of the inner container body 3 and the outer container body 2 can be ensured.
