ある。(Means for Solving the Problems) The present invention aims to solve the above-mentioned problems and provide a container whose opening can be extremely easily reclosed and reopened even after the seal has been opened.
The gist is that it consists of a highly rigid plastic container body with a flange formed around the opening of the storage recess, and a lid material that is sealed around the entire circumference of the flange to seal the opening. A portion of the flange is curved so as to be convex toward the container body, and an unsealed portion communicating with the storage recess is provided inside the sealed portion of the flange curved portion, and the flange curved portion is further provided with an unsealed portion extending across the unsealed portion. This packaging container is characterized in that an opening kerf is provided, and the end of the flange curved portion that is bent from the opening kerf remains in the container body through the lid.
以下、本考案を添付図面に基いて詳細に説明す

ている。 As shown in FIGS. 1 to 4, the packaging container of the present invention includes a container body 2 made of a highly rigid plastic with a flange 1 formed around the opening of the storage recess;
a lid member 3 that is sealed around the entire circumference of the flange 1 to seal the opening;
A part of the flange is curved so as to be convex toward the container body side (that is, downward in this example), and an unsealed part 5 is provided inside the seal part 4 in this flange curved part 11 to communicate with the storage recess, and furthermore, An opening groove 6 is provided in the flange curved portion 11 so as to cross the unsealed portion 5, and the end portion of the flange curved portion 11 that is bent from the opening groove 6 remains in the container body via the lid member 3. It is characterized by the fact that

材端３１も湾曲状態で両端を固定されているので
スナツプ作用が働いて開口部を強く閉止し内容物
が飛び出さない。 As a result, although the seal portion 4 seals the seal before opening, after the seal between the lid member 3 and the flange 1 is opened at the flange curved portion 11, as shown in FIGS. Since there is a sealing part 5, the unsealing part can be opened by simply lifting the lid end 31 upward as shown in FIG.
1 is further curved downward to have a large opening, and the unsealed portion 5 serves as a guide tube to allow the contents to be taken out.
After taking it out, if the pressure from both sides is released and the lid end 31 is pushed down slightly, the closed state will be restored as shown by the dotted line 31 in FIG. 3, and the curved flange 1 Since the end 31 of the lid material is also curved and fixed at both ends, a snap action works to strongly close the opening and prevent the contents from falling out.

大きい厚さのものの方がフランジ湾曲部１１によ
るスナツプ作用が強くなるので好ましい。 In the present invention, the container body 2 can be formed by vacuum or pressure forming a sheet of plastic such as polyvinyl chloride, or by injection molding of plastic, and is made of a relatively rigid material.
A larger thickness is preferable because the snapping action of the flange curved portion 11 is stronger.

ール部５を横断するように開封用切溝６を設けて

きる。 If an opening cut groove 6 is provided to cross the unsealed part 5 of the flange curved part 11 as shown in FIG. 2, the flange end can be folded back from the cut groove 6 as shown in FIG. If so, it can be opened easily.
蓋材３はプラスチツクフイルム、紙、アルミニ
ウム箔、またはこれらにシール層を積層したもの

本体２の開口部を密閉し得るものであればよい。
このことにより、フランジ湾曲部１１端部は蓋材
端３１にシールされ、折つた後も蓋材３を介して
容器本体２に残る。 In order to seal the lid member 3 to the flange 1 of the container body, any material that can seal the opening of the container body 2 may be used, such as thermal welding seal or adhesive bonding.
As a result, the end of the flange curved portion 11 is sealed to the lid end 31 and remains on the container body 2 via the lid 3 even after being folded.

とができる。 Note that by leaving the broken end of the flange curved portion 11 at the end 31 of the lid, the rigidity and restoring force of the end 31 of the lid are increased, and the above-described closing action of the opening becomes more reliable. Furthermore, if the lid end 31 is folded back upward, the flange end, which was convex downward, becomes convex upward, so that the open state can be easily maintained.
