た構造を特徴とする容易開封容器である。[Detailed description of the invention] The invention relates to an easy-to-open container covered with a laminated flexible lid containing aluminum foil, etc.
The top surface of the container opening is leveled, the shape of the high part that is to be bonded to the lid is a continuous annular shape, and at least the outer circumference is serrated, and the lid is covered with the container opening. This is an easy-to-open container featuring a strongly bonded structure.
プラスチック成形容器の多くは、従来真空成形方法によ
り安価に製造し得るのみでなく、能率的にして確実に密
封し得る故、各種の収容容器の簡易包装用に使用されて
来た。Many plastic molded containers have conventionally been used for simple packaging of various storage containers because they can not only be manufactured at low cost by vacuum forming methods, but also be efficiently and reliably sealed.
そして製造工程が非常に簡単である利点を採り、最近は
、加熱殺菌を施すような保存食品用に真空成形に代って
射出成型容器を使用するようになった。Taking advantage of the extremely simple manufacturing process, injection molded containers have recently come to be used in place of vacuum molding for preserved foods that require heat sterilization.
そこで、密封後に加熱殺菌を施すような保存食品用の容
器にあっては、加熱の際における内圧の上昇に耐える強
度を具えた密封を施さねばならない。Therefore, in containers for preserved foods that are heat sterilized after being sealed, the seal must be strong enough to withstand the rise in internal pressure during heating.
ところで、アルミ箔とプラスチックスフィルムとを積層
した、従来のプラスチックス成型容器用蓋材をもって被
蓋する場合であっても、被蓋接着強度については、従来
よりも接触強度を非常に強化しであるから、指先でもっ
て蓋体を容器から引き剥がして開口することが容易でな
い。By the way, even when covering with the conventional lid material for plastic molded containers, which is made by laminating aluminum foil and plastic film, the contact strength of the lid is much stronger than before. Because of this, it is not easy to peel the lid off the container with your fingertips and open it.
本考案は、加熱殺菌に耐える強い接着強度を具えた積層
可撓性蓋体を被蓋し乍ら、容易に開封し得るものである
こと下記の通り。The present invention covers the lid with a laminated flexible lid that has strong adhesive strength that can withstand heat sterilization, but can be easily opened as described below.
第１図に示す如く容器１０ ａの胴壁１１ ａ上端に放
射方向へ延設した口縁鍔部１２ ａの上面部１３ａにお
いて、第２図に示す如く被蓋する蓋体２０ ａの裏面と
接する上面１３Ｈの内側周部を高部１４ ａとなし蓋体
２０ａの裏面に接しない低部１５ａを上平面部の外側周
部に形成し、且つ前記高部１４ａの外側段部を円周方向
に鋸歯状とし、以て高部１４ ａの外側縁に多数の放射
方向への尖端部１６ａを形成する。As shown in FIG. 1, the upper surface part 13a of the mouth rim flange 12a extending in the radial direction at the upper end of the body wall 11a of the container 10a is connected to the back surface of the lid 20a to be covered as shown in FIG. The inner periphery of the upper surface 13H that is in contact with the upper surface 13H is formed as a high portion 14a, and the lower portion 15a that does not contact the back surface of the lid body 20a is formed on the outer periphery of the upper plane portion, and the outer stepped portion of the high portion 14a is formed in the circumferential direction. The outer edge of the high portion 14a has a plurality of radially extending points 16a.
この環状高部１４ａの形成は容ご器１０ ａの成形時に
行う故、成形製造は容易に行い得る。Since the annular high portion 14a is formed during the molding of the container 10a, the molding process can be easily performed.
このような容器に積層可撓性性合成樹脂製蓋材２０ ａ
を被蓋してシールを施す場合に、当然に前記高部１４
ａの形状に応じた接着が生じる。Laminated flexible synthetic resin lid material 20a on such a container
When covering and sealing, naturally the high portion 14
Adhesion occurs depending on the shape of a.
即ち、容器口縁鍔部１２ａと蓋体２０ ａとの接着部分
１７ ａは容器口縁鍔部１２ ａに沿って環状であるが
、該環状接着部分の外側縁が鋸歯状にして放射方向へ多
数の尖端部１６ａを具えた形状の接着面となる。That is, the adhesive portion 17a between the container rim flange 12a and the lid 20a is annular along the container rim flange 12a, and the outer edge of the annular adhesive portion is serrated in the radial direction. The adhesive surface has a shape including a large number of pointed ends 16a.
従って従来の如く鍔部上面部１３Ｈの全面を単一平面と
してこれに蓋体をシールした場合に比較して接着面積が
数分の−に減少する。Therefore, compared to the case where the entire surface of the upper flange portion 13H is made into a single plane and the lid is sealed to this as in the conventional case, the bonding area is reduced to several times less.
加えるにシールした蓋体２０ａを剥離する場合における
初期の剥離現象が接着部分の尖端部１６ａにおいて生じ
るから、初期剥離が非常に容易であり蓋体の除去も容易
である。In addition, when the sealed lid 20a is peeled off, the initial peeling phenomenon occurs at the tip 16a of the bonded portion, so the initial peeling is very easy and the lid is also easy to remove.
そして、接着部分となる環状高部１４ ａはその外周段
部を鋸歯状とすることにより尖端部１６ ａを外側縁に
多数有する故、蓋体２０ ａを容器１０ ａに被蓋する
に際し蓋体と容器との向きを定める必要がなく又、開封
に際しても全周のどの位置からでも開封を容易に行ない
得るものである。The annular high part 14a, which becomes the bonding part, has a sawtoothed outer circumferential step and has many pointed parts 16a on the outer edge, so when the lid 20a is attached to the container 10a There is no need to determine the direction of the container and the container, and the container can be opened easily from any position around the circumference.
更に、環状高部１４ ａをもって蓋体２０ ａを接着す
ることにより接着面積が減少する故、接着面に内容物等
が異物として付着する可能性が減少し、又、異物が付着
してもシール時に接着面である環状高部１４ ａ上面か
ら低部１５ ａ又は容器内に押し出され、接着部分１７
ａに残存して接着不良を生じさせる虞れを少くする利
点をも有する。Furthermore, since the adhesion area is reduced by adhering the lid body 20a with the annular high portion 14a, the possibility that contents etc. will adhere as foreign matter to the adhesion surface is reduced, and even if foreign matter adheres, the seal will not be damaged. Sometimes it is pushed out from the upper surface of the annular high part 14a, which is the adhesive surface, into the lower part 15a or into the container, and the adhesive part 17
It also has the advantage of reducing the risk of remaining in the film and causing poor adhesion.

接着していても剥離を容易に行い得る利点を有する。In this way, the second embodiment has the lid body 20b and the container mouth rim flange 1.
Not only is the area with 2 b reduced by several minutes compared to the case where it is bonded to the conventional mouth rim flange, but the outer periphery of the bonded portion is serrated and forms a tip 16b in the radial direction. As in the first embodiment, the seal can be easily opened from any position around the circumference, and since the adhesive portion 17b is narrow like a meandering line, foreign matter attached to the adhesive surface can be easily opened. It is more easily pushed out to the lower parts 15 b and 15 b' of the outer and inner circumferential parts than in the case of the first embodiment, and it is possible to prevent adhesion failure due to foreign matter, and even when the package is opened, the adhesive part remains intact. Since the width of 17b is narrow, there is an advantage that even if the lid body and the container are firmly adhered to each other, they can be easily peeled off.
、尚、環状高部１４ｂと内側周部１５ｂ′との境界段差
部分は鋸歯状に限るものではない。Note that the boundary step portion between the annular high portion 14b and the inner circumferential portion 15b' is not limited to a sawtooth shape.
