【発明の詳細な説明】
本発明は、容器の封緘機構、特に液体飲料等が充填され
て市販される容器の封緘機構に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing mechanism for a container, and particularly to a sealing mechanism for a container filled with a liquid beverage or the like and sold on the market.
最近、牛乳、ジュース等の液体飲料は紙容器に充填され
て販売されることが多くなっている。Recently, liquid beverages such as milk and juice are often sold in paper containers.
上記傾向に伴ない紙容器も種々なる形状のものが考えら
れ、使用宮れている。In line with the above-mentioned trend, paper containers of various shapes have been considered and are no longer used.
これらの容器は一旦使用された後は廃棄されてしまう関
係上、できる限り簡単な構造であることを要すると共に
、容器を覆う蓋体にあっても充填される液体飲料が漏洩
せず、しかも開封容易な構成としなければならな賜した
がって従来、第１図ａ図示の容器が使用されてむり、図
において１は容器であって内部には図示しない液体飲料
等が充填される。Since these containers are discarded after being used, they need to be as simple as possible in structure, and even if the lid covers the container, the liquid beverage that is filled in the container will not leak out, and the container cannot be opened. Conventionally, the container shown in FIG. 1a has been used because the structure must be simple. In the figure, reference numeral 1 designates the container, and the interior thereof is filled with a liquid beverage or the like (not shown).
２は前記容器の開口部を覆う蓋体であって、一般的には
アル□箔が用いられる。Reference numeral 2 denotes a lid that covers the opening of the container, and generally aluminum foil is used.
そして第１図ａ図示のＸ−Ｙ断面からみた具体的な封緘
手段は同図す、ｃ、ｄに夫々模式的に示される如く種々
なる変形が存在する。The specific sealing means seen from the X-Y cross section shown in FIG. 1A has various modifications as schematically shown in FIG.
しかし、いずれの封緘手段を採用しても容器１の開１コ
部周縁に対して蓋体２としてのアル□箔が容易に粘着し
得る構成としなければならず、したがってアルミ箔下面
に熱融着性ワックスが塗布されて容器の開口部周縁に貼
着される。However, no matter which sealing means is adopted, the structure must be such that the aluminum foil as the lid body 2 can easily adhere to the periphery of the open part of the container 1, and therefore the aluminum foil must be heat-fused to the bottom surface of the aluminum foil. Adhesive wax is applied and adhered to the periphery of the opening of the container.
しかしながら塗布されるワックスを容器の開口部周縁の
みに限定して塗布することは実際問題として不可能であ
り、残余部分が液体飲料側に露出することは避けられず
、また熱融着性ワックスと呼ばれるものには、食品衛生
上好ましくないものが溶出する危険がある。However, as a practical matter, it is impossible to apply wax only to the periphery of the opening of the container, and it is inevitable that the remaining part will be exposed to the liquid beverage side. There is a risk that substances that are undesirable from a food hygiene perspective will leach out.

うにすると接着強度が強すぎて容易に全面開封ができず
、他の開封手段を付加しなければならない。To prevent this, polyethylene is applied to the entire bottom surface of the aluminum foil.
A configuration in which a sheet is pasted and fused to the opening of the container via the polyethylene sheet is conceivable, but in this case, the adhesive strength is too strong and the entire surface cannot be opened easily, and other opening methods are required. must be added.

口部周縁に接着するようにした容器の封緘機構を提供す
ることを目的としている。The present invention was made with the aim of solving the above-mentioned problem, and a polyethylene sheet with a width that can cover the periphery of the opening of the container is heat-fused on the lower surface of the aluminum foil that forms the upper surface of the lid. It is an object of the present invention to provide a container sealing mechanism in which the lid body having the overlapping structure is adhered to the periphery of the opening of the container using polyethylene or a sheet.
以下図面を参照しつつ実施例を説明する。Examples will be described below with reference to the drawings.
第２図は本考案になる容器の封緘機構を示す一部断面図
、第３図は蓋体の分解構造図、第４図は容器の開封状態
を示す一部断面図を示す。FIG. 2 is a partial sectional view showing the sealing mechanism of the container according to the present invention, FIG. 3 is an exploded structural view of the lid, and FIG. 4 is a partial sectional view showing the container in an unsealed state.
第２図にむける符号１，２は第１図に対応する。Reference numerals 1 and 2 in FIG. 2 correspond to those in FIG.
３は蓋体２の上面を形成するアルミ箔であって、容器開
口部周縁４を覆って、一部余裕分が開口部周縁４からは
み出す形状寸法を有する。Reference numeral 3 denotes an aluminum foil forming the upper surface of the lid body 2, and has a shape and size that covers the container opening periphery 4 and a part of the margin protrudes from the opening periphery 4.
５はアル□箔下面に塗布されるワックスの塗布層であっ
て熱融着性を有している。Reference numeral 5 denotes a wax coating layer applied to the lower surface of the aluminum foil, which has thermal adhesive properties.
またこのワックス塗布層５を紙にワックスを含浸プせた
もので置換することも可能である。It is also possible to replace the wax coating layer 5 with paper impregnated with wax.
６はポリエチレン、シートであって、蓋体２上面を形成
するアルミ箔に貼着されて一体になっている。Reference numeral 6 denotes a polyethylene sheet, which is integrally attached to the aluminum foil forming the upper surface of the lid body 2.
そして前記ポリエチレン、シート６゛ａ器１の開口部周
縁４に対して同心円状を有している（第３図参照）。The polyethylene sheet 6a has a concentric circular shape with respect to the opening periphery 4 of the container 1 (see FIG. 3).

縁における７ａ、７ｂの位置で裂断するので、その裂断
線７ａ。Next, the unsealing of the container will be explained with reference to FIG. 4. As is clear from FIG.
Peeling occurs between the polyethylene sheet 6 and the wax coating layer 5, and at the same time, the polyethylene sheet 6 tears at positions 7a and 7b on both edges of the adhesive surface that is attached to the opening of the container 1, so that the tear line 7a.
７ｂが容器開口部全周に沿って拡大し全面開封に至る。7b expands along the entire circumference of the container opening until the entire surface is opened.
なお上記説明から理解できるように、第５図の如くアル

に生じ、前記第４図の場合よりもきれいな開口が得られ
る。As can be understood from the above explanation, by directly pasting the polyethylene sheet 6 without providing the wax coating layer 5 in the central part of the aluminum foil 3 as shown in FIG.
In the center part of the lid body 2, aluminum foil 3 and polyethylene,
The adhesive force with the sheet 6 becomes stronger, and when the polyethylene sheet 6 is opened as shown in FIG. A clearer opening can be obtained than in the case of .

た例である。FIG. 6 shows a polyethylene sheet 6 placed around the opening of the container 1 in order to clean the periphery 4 of the container opening without forming a tear line 7a that occurs on the outside of the adhesive surface of the opening when the container is opened in the manner shown in FIG. This is an example in which the dimensions are such that the arrangement source is located inside the peripheral edge 4.

ことが可能であるという効果を奏する。As explained above, the present invention applies heat-fusible wax to the lower surface of the aluminum foil that forms the upper surface of the lid, and also adheres a polyethylene sheet that matches the opening of the container to form an overlapping structure. Since the wax is attached to the periphery of the container, the wax does not come into contact with the liquid beverage or the like filled in the container, and the sealed opening can be opened efficiently.
