Description
【考案の詳細な説明】 本考案は容器密封蓋に関するものである。[Detailed explanation of the idea] The present invention relates to a container sealing lid.

に嵌着する周突起4を突設することが行なわれている。Conventionally, when a lid 1 which has been formed with rough sealing as shown in FIG. To facilitate fitting, a circumferential projection 4 is generally provided on the inner surface of the lid to fit into the upper opening of the container.
しかしながら従来の嵌合を容易にするためのこの種の周

を起し易く、又蓋材が非結晶性の合成樹脂からなる場合
でも、成形時の残留応力、蓋の大きさと樹脂の肉厚との
関係から上記と同様の変形がおこり易い。However, in conventional lids with protruding peripheral protrusions of this type to facilitate fitting, when crystalline synthetic resin is used, residual stress from crystallization of the synthetic resin and molding of the peripheral protrusions Even if part or all of the lid is prone to deformation such as curving or twisting, and even if the lid material is made of amorphous synthetic resin, the relationship between residual stress during molding, lid size, and resin wall thickness. deformation similar to the above is likely to occur.
第3図の点線はその彎曲変形を示す。The dotted line in FIG. 3 shows the curved deformation.
上記の現象が蓋材に生じた場合は、容器に内容物を詰め

問題が発生する。If the above phenomenon occurs in the lid, it will be difficult to fit the lid in the desired position at the top opening of the container when filling the container with contents and closing the lid. During sealing, the lid may be misaligned, making it difficult to completely fit, and other problems may occur, such as the lid falling off before heat-sealing, or the automatic packaging machine not being able to automatically supply the lid by suction.

の脱落や位置ずれを防止することが行われている。Therefore, when using conventional deformed lids of this type, it is necessary to slow down the packaging process to prevent the lid from falling off or shifting its position on the container body. During this period, the lid is held by various pressure means to prevent the lid material from falling off or shifting its position.
本考案者らは、かかる従来方法による問題を解決すべく
研究した結果、従来の蓋材の屈曲等の変形が蓋体の構造
を変更することにより避けられることを発見して本考案
をなすにいたった。As a result of research to solve the problems caused by the conventional method, the present inventors discovered that deformation such as bending of the conventional lid material can be avoided by changing the structure of the lid body. It happened.
以下図面に基づいて本考案を詳細に説明する。The present invention will be explained in detail below based on the drawings.
第1.2.3図は前述した如〈従来の容器蓋を示す。1.2.3 shows a conventional container lid as described above.
蓋材は紙1a、アルミ箔1b、プラスチック1Cを積層

を接着しである。The lid material is shown as a laminate of paper 1a, aluminum foil 1b, and plastic 1C, with peripheral protrusions 4 on the plastic layer 1C.
It is glued together.
かがる蓋材のプラスチック層に周突起を接着したものの
欠点は前述した如くである。The drawbacks of the circumferential protrusion bonded to the plastic layer of the overlocking lid material are as described above.

前記数個のリブの近傍まで伸張せしめられている。In the present invention, the front surface of the lid is shaped flat, and the back surface is provided with a large number of intermittent or independent ribs 6 (projections), and at least some of these ribs should be fitted with the lid and heat-sealed. It is adapted to come into contact with the inner wall surface of the container body at a predetermined position on the container body, and further, other arbitrary ribs are formed continuously or intermittently radially from the center of the lid, and each terminal end thereof is formed in the number mentioned above. It is extended to the vicinity of each rib.
又、この蓋の内面に付設する多数個のリブ6は、蓋の大

の個数、大きさ、位置を決めることが必要である。Furthermore, the number, size, and position of the numerous ribs 6 attached to the inner surface of the lid must be determined by taking into consideration the size, shape, and material characteristics (presence or absence of crystallinity) of the lid. .
図中周縁の斑点部分7はシール部を示す。Spotted portions 7 on the periphery of the figure indicate seal portions.
本考案で用いられる蓋の基材の材質構成としては、紙と
プラスチック、紙とプラスチックとアルミ箔などが通常
用いられる。The material composition of the base material of the lid used in the present invention is usually paper and plastic, paper, plastic, and aluminum foil, etc.
又蓋の基材の形状は円形、正方形、長方形、多角形など
いかなる形状のものでも可能である。Further, the shape of the base material of the lid may be any shape such as circular, square, rectangular, or polygonal.
蓋の基材の内面に設けるリブの形状としては、第4,5

成されたリブを有していなければならない。The shapes of the ribs provided on the inner surface of the base material of the lid are 4th and 5th.
As shown in the figure, dotted and intermittent circumferential lines and multiple circumferential lines, or
radial array of points or lines, and combinations thereof;
Any type of lid may be used, but it must at least have ribs radially formed from the center of the lid.
また、突起の大きさ、高さは蓋材の強度及び大きさ、(
蓋が円形の場合直径、方形の場合各辺の長さ)に応して
適宜選択すればよい。In addition, the size and height of the protrusion are determined by the strength and size of the lid material, (
If the lid is circular, it may be selected appropriately depending on the diameter (if the lid is circular, the length of each side if it is rectangular).

がある。The lid material with the above structure has radial ribs, and these ribs extend from the center of the lid to the periphery, which prevents deformation such as bending and curving of the lid, and keeps the surface of the lid flat. Therefore, the automatic supply of lids by the suction of the automatic packaging machine is not inhibited, and unlike conventional methods, a special support device is not required in the closing process. The lid material can be fitted and held in a predetermined position without deterioration, improving heat-sealability and providing a sealed container with a flat lid top surface after heat-sealing.
It is characterized by the ability to produce sealed packaged foods with excellent commercial value.
