容器１の上部開口部２周縁に鍔部３を設け、この容器１の上部開口部２をフィルム４で覆うことで密閉しこのフィルム４を取り除くことで開口する容器１に上方から被嵌する容器の蓋において、蓋体５の周縁部に前記鍔部３の鍔幅に合致する被嵌凹部６を設け、この被嵌凹部６の外側垂下部７に前記鍔部３の外縁に係止する係止部８を一箇所若しくは上下に複数箇所設けると共に、この被嵌凹部６の内側垂下部９を前記フィルム４を取り除いた状態で前記容器１の上部内面10に面接するように構成し、前記フィルム４で前記上部開口部２を密閉している状態では前記内側垂下部９は前記容器１内に入らず、前記一箇所に設けた係止部８若しくは前記複数箇所に設けた下側の係止部８に前記鍔部３の外縁が係止して被嵌係止されるように構成したことを特徴とする容器の蓋に係るものである。
A container 3 that is provided with a flange 3 on the periphery of the upper opening 2 of the container 1, is sealed by covering the upper opening 2 of the container 1 with a film 4, and is fitted onto the container 1 that is opened by removing the film 4 from above. In the lid, a fitting recess 6 that matches the collar width of the flange 3 is provided on the peripheral edge of the lid 5, and the outer hanging portion 7 of the fitting recess 6 is engaged with the outer edge of the flange 3. The stopper 8 is provided in one place or a plurality of places on the upper and lower sides, and the inner hanging part 9 of the fitted recess 6 is configured to come into contact with the upper inner surface 10 of the container 1 with the film 4 removed. In the state where the upper opening 2 is sealed at 4, the inner hanging part 9 does not enter the container 1, but the locking part 8 provided at the one place or the lower locking provided at the plurality of places. The outer edge of the collar part 3 is engaged with the part 8 so as to be fitted and locked. It relates to a lid of a container according to claim.
容器１の上部開口部２をフィルム４で覆った状態において、この容器１に上から蓋をする時には、蓋体５の外側垂下部７の下側を容器１の鍔部３の外縁に当接させて蓋体５を押圧すると、前記内側垂下部９は前記容器１内に入らず、前記鍔部３の外縁が外側垂下部７の係止部８で係止することになって、蓋体５が容器１に被嵌係止される。
When the upper opening 2 of the container 1 is covered with the film 4, when the container 1 is covered from above, the lower side of the outer drooping portion 7 of the lid 5 is brought into contact with the outer edge of the flange 3 of the container 1. When the lid 5 is pressed, the inner hanging portion 9 does not enter the container 1, and the outer edge of the flange portion 3 is locked by the locking portion 8 of the outer hanging portion 7. 5 is fitted and locked to the container 1.
一方、容器１の上部開口部２からフィルム４を取り除いた状態においては、上述した前記鍔部３の外縁が外側垂下部７の係止部８で係止した状態から更に蓋体５を押圧すると、被嵌凹部６の内側垂下部９が前記容器１の上部内面10に面接すると共に、例えば、前記係止部８を上下に二箇所設けた場合には、更に前記鍔部３の外縁が外側垂下部７の上側の係止部８で係止して蓋体５が容器１に被嵌係止されることになる。即ち、蓋体５の内側垂下部９によって前記容器１が密閉状態になると共に、例えば、前記係止部８を上下に二箇所設けた場合には、外側垂下部７の上側の係止部８で前記鍔部３の外縁が係止されて容器１の密閉状態が保持されることになる。
On the other hand, when the film 4 is removed from the upper opening 2 of the container 1, when the lid 5 is further pressed from the state in which the outer edge of the flange 3 is locked by the locking portion 8 of the outer hanging portion 7. In addition, when the inner hanging portion 9 of the fitted recess 6 is in contact with the upper inner surface 10 of the container 1, for example, when the locking portion 8 is provided in two places at the top and bottom, the outer edge of the flange portion 3 is further outside. The lid 5 is fitted and locked to the container 1 by the locking portion 8 on the upper side of the hanging portion 7. That is, the container 1 is hermetically sealed by the inner hanging portion 9 of the lid 5, and, for example, when the locking portion 8 is provided at two locations in the vertical direction, the upper locking portion 8 of the outer hanging portion 7. Thus, the outer edge of the flange 3 is locked and the sealed state of the container 1 is maintained.
更に、容器１の上部開口部２からフィルム４を取り除いて蓋20で容器１を密閉している状態から蓋20を外す時、蓋20の周縁部に設けた被嵌凹部６の外側垂下部７を持ち上げるようにして蓋20の上側の係止部８から順に下側の係止部８へと容器１の水平鍔部３を外すと、容器１の上部内面10に面接していた被嵌凹部６の内側垂下部９が容器１の上部内面10から外れて蓋20を外すことができることになる。
Further, when the film 20 is removed from the upper opening 2 of the container 1 and the cover 20 is removed from the state in which the container 1 is sealed with the cover 20, the outer drooping portion 7 of the fitted recess 6 provided on the peripheral edge of the cover 20. When the horizontal flange 3 of the container 1 is removed from the upper locking portion 8 of the lid 20 in order to the lower locking portion 8 so as to lift up, the fitted recess that was in contact with the upper inner surface 10 of the container 1 Thus, the inner hanging part 9 of the container 6 is detached from the upper inner surface 10 of the container 1 and the lid 20 can be removed.
