むときには、簡単に引剥して開封することができること
が望ましい。Generally, in the airtight lid as described above, the sheet member that is in close contact with the daily drinking opening of the lid body is It is desirable that the package adhere tightly and sufficiently protect the contents, while being able to be easily peeled off and opened when the contents are to be consumed.
本考案者は、上記のような要望について種々検討の結果
、密閉蓋の蓋本体とシート部材との密着面のいずれか一
方をエチレン−アクリル酸共重合体樹脂の層、他方をア
ルミニウム箔の層で構成したところ、蓋本体とシート部
材とは充分に密着し得ると共に易開封性を有することを
見出して本考案を完成したものである。As a result of various studies regarding the above-mentioned requests, the inventor of the present invention decided to create a layer of ethylene-acrylic acid copolymer resin on one side of the contact surface between the lid body and the sheet member of the airtight lid, and a layer of aluminum foil on the other side. The inventors completed the present invention by discovering that the lid body and the sheet member can be brought into close contact with one another and are easy to open.
以下図面を用いて本考案の好ましい実施例につき詳細な
説明を行なう。Preferred embodiments of the present invention will be described in detail below with reference to the drawings.
第１図、第２図において、１０はカップ状の容器本体で
あす、１２は密閉蓋である。In FIGS. 1 and 2, 10 is a cup-shaped container body, and 12 is a sealing lid.
容器本体１０及び密閉蓋１２はともに紙を主体としてな
るものである。Both the container body 10 and the sealing lid 12 are mainly made of paper.
密閉蓋１２は内方に軌み日用開口部１４を有する蓋本体
１６と、開口部１４を密閉するシート部材１８とからな
り、共に紙を主材として形成されている。The sealing lid 12 consists of a lid main body 16 having a daily use opening 14 on the inside, and a sheet member 18 for sealing the opening 14, both of which are mainly made of paper.
而して、本考案においては蓋本体１６とシート部材１８
は保存時は容器内の密閉性を充分保つ反面、開封に際し
てはシート部材１８を容易に蓋本体１６から引き剥しう
るよう、第３図示の如き工夫された層構造を有している
。Therefore, in the present invention, the lid main body 16 and the sheet member 18
The container has a layered structure as shown in the third figure so that the container can be kept sufficiently airtight during storage, while the sheet member 18 can be easily peeled off from the lid body 16 when unsealed.
すなわち、第３図に示すように蓋本体１６とシート部材
１８との密着面ａのいずれか一方をエチレン−アクリル
酸共重合体樹脂の層２０で、他方をアルミニウム箔の層
２４て゛構成するものである。That is, as shown in FIG. 3, one of the contact surfaces a between the lid body 16 and the sheet member 18 is made up of a layer 20 of ethylene-acrylic acid copolymer resin, and the other is made up of a layer 24 of aluminum foil. It is.
而して、本考案において、上記の如き層構造を形成する
方法としては、上記のような樹脂のフィルムないしシー
ト又はアルミニウム箔を蓋本体とシート部材とに積層す
るか、或は、上記のような樹脂を含む組成物を蓋本体と
シート部材とにコーティングして、それぞれ蓋本体とシ
ート部材とに上記の樹脂の層を形成し、しかる後該蓋本
体とシート部材とをそれぞれに形成した樹脂の層を熱融
着させること等によって行うことができる。Therefore, in the present invention, the method for forming the layered structure as described above is to laminate the resin film or sheet or aluminum foil as described above on the lid body and the sheet member, or to form the layered structure as described above. The lid body and the sheet member are coated with a composition containing the resin, a layer of the resin described above is formed on the lid body and the sheet member, respectively, and then the lid body and the sheet member are formed with the resin. This can be done by heat-sealing layers of the above.
尚、本考案において、上記の樹脂の層は、少なくとも蓋
本体とシート部材との密着面の範囲内に形成されていれ
ば充分である。In the present invention, it is sufficient that the resin layer is formed at least within the area of the contact surface between the lid body and the sheet member.
次に、本考案において、蓋本体およびシート部材として
は、紙を主体としたもので、各種の紙に、樹脂のフィル
ムないしシート、アルミニウム箔等をラミネートした浸
透性のない表面を有するものを使用することができる。Next, in the present invention, the lid body and sheet members are mainly made of paper, and are made of various types of paper laminated with resin films or sheets, aluminum foil, etc., and have a non-permeable surface. can do.
次に又、本考案において蓋本体とカップ状容器本体の開
口縁との密着は、図示しないが例えば蓋本体の下面に熱
溶着する合成樹脂層（例えばポリエチレン樹脂層）を設
け、これと容器本体の内面に被覆された合成樹脂層とを
熱溶着させることによって行うことができる。Next, in the present invention, the close contact between the lid body and the opening edge of the cup-shaped container body is achieved by providing, for example, a synthetic resin layer (for example, a polyethylene resin layer) heat-welded to the lower surface of the lid body (not shown), and this and the container body. This can be done by thermally welding a synthetic resin layer coated on the inner surface of the material.
上記のような本考案にかかる密閉蓋は、上記のように蓋
本体とシート部材とが共に紙を主体として構成され、か
つそれらの接合部は、特定の樹脂の層とアルミニウム箔
