【発明が解決しようとする課題】蓋付き容器は、物品を
入れて蓋をしたあと、その蓋が不用意に開かないように
粘着テープやステープルで止めることが一般に行われて
いるが、食品を入れる容器の場合は安全および衛生の点
に問題があり、蓋を止めるのに手間が掛かる。In the case of a container with a lid, it is a common practice to put an article on the lid and then close the lid with adhesive tape or staples to prevent the lid from being opened carelessly. In the case of a container to be filled, there are safety and hygiene problems, and it takes time to stop the lid.

いる。BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a packaging container with a lid according to the present invention. The packaging container shown in FIG. 1 is a so-called square container, 1 is a container body, and 2 is a lid that is shallower than the container body 1. Frame-shaped projecting edges 3 and 4 are formed on the peripheral edges of the container body 1 and the lid 2 respectively.

As shown by the solid line in FIG.
Point diagonally downward . When the lid 2 is opened, the knobs 5 at the symmetrical positions are pinched and pulled outward as shown by the chain line in FIG. Then, the vicinity of the frame-shaped overhanging edge 3 of the container body 1 connected to the knob 5 extends and the protrusion 4a of the lid 2 is pushed up, so that the protrusion 4a with respect to the lower edge of the downward facing outer edge 3a of the container body 1 is raised. The engagement is released, and the lid 2 is opened as if to float as shown in FIG. That is, the lid 2 can be removed from the container body 1 without putting any hand on the lid 2.

構成であるから、次のような種々の効果を持っている。
蓋を閉じるときは従来の係止構造付きの容器と同じ要領
で、すなわち容器本体に蓋をかぶせて押すだけの簡単な
操作で閉じることができる。Since the packaging container with a lid according to the present invention has the above-described structure, it has the following various effects.
When closing the lid, the lid can be closed in the same manner as a conventional container with a locking structure, that is, by a simple operation of putting the lid on the container body and pushing.

身からの滲出を防ぐことができる。When the lid is opened, the lid can be easily unlocked by simply grasping the knob on the container body side and pulling outward, and the lid can be opened. That is, even if the fitting of the frame-shaped overhanging edges is considerably strong, they can be easily removed. Therefore, by fitting the frame-shaped overhanging edges of the lid and the container body around the entire circumference to strengthen the fitting, it is possible to prevent the lid from being detached or exuding from the contents during transportation or handling.

中身が不用意にこぼれたり飛び出す虞がない。したがっ
て容器本体を手で持ちにくいトレー形の容器の場合でも
安定して開けることができる。Since it is not necessary to hold the lid to open the lid, the lid can be opened while the container is placed on a table or a knee. When the lid is opened, the container is stable and the contents are There is no risk of accidentally spilling or jumping out. Therefore, even if the container body is a tray-shaped container that is difficult to hold by hand, it can be opened stably.
