Closers are required by consumers to have sealing performance that reliably preserves the contents of the container until it is opened, and functionality that allows the contents to be safely and easily taken out as needed.6 On the other hand, From the manufacturer's side, they not only fully meet the needs of consumers, but also be inexpensive, withstand temperature changes and external forces in the product production line, be compatible with automation of sealing, and protect the contents from the time they reach the consumer, especially Clothes are required to retain carbon dioxide gas, maintain vacuum, and have barrier properties against oxygen, moisture, aroma components, etc., and closures are being developed depending on the type of contents and usage conditions.

こと、内容物を簡単にとり出せること等の特徴を有する
ところからその生産は着実に拡大しでいる。Since the mid-1960s, products such as sake, juice, wine, jelly, etc. have been introduced in cup-shaped containers that combine a wide-mouth glass container with a special aluminum foil tear-off cap. has been commercialized, and its production has steadily expanded due to the spread of vending machines and its characteristics such as being easily portable, easy to open and can be opened anywhere, and the contents easily taken out.

ため、アルミニウム箔は耐食性コーティングが必要であ

も剥離や亀裂がおきず、内容物に侵されず、また内容物
を汚染しないものである必要があることである。In this type of sealing method, the inner surface of the cap comes into contact with the contents, so the aluminum foil needs to be coated with a corrosion-resistant coating.This coating will not peel or crack even when clipped during sealing, and will not be attacked by the contents. It must be something that does not contaminate the contents.

けられた。Furthermore, since sealing is impossible due to the contact between the aluminum foil and the glass, the use of a sealing material is required. At this time, it would be preferable to use a gasket made of inexpensive foamed plastic, but this material has poor elasticity.
In order to achieve a complete seal, it was necessary to use an expensive plastisol compound6.Furthermore, because the container was filled hot and then cooled to room temperature after sealing, the inside of the container was under a slight vacuum.
For this reason, even if the cap was opened along the side score of the skirt part, the cap could not be removed easily, and the contents often spilled due to the recoil from using too much force.

The aim was to develop a cap material that was compatible with the conventional tear-off cap and its easy opening.

The present invention provides a cap material for a glass container that is sealed using a combination of heat sealing and clipping, in which a synthetic resin film that is adhesive to glass is adhered to the inside of an aluminum foil.

を特徴とするガラス容器の封緘方法を開発した。Furthermore, the basic structure is to cover the filled glass container with a cap made by laminating a synthetic resin film that is adhesive to glass onto the inside of aluminum foil, and to seal it using a combination of heat sealing and clipping. We have developed a unique method for sealing glass containers.

る。In the present invention, a synthetic resin that is adhesive to glass refers to an unsaturated carboxylic acid obtained by graft polymerizing polyethylene, polypropylene, etc. with an unsaturated carboxylic acid such as maleic anhydride alone or a mixture of such unsaturated carboxylic acid and an olefin. Examples include modified polyolefin resins, ethylene-acrylic acid copolymers, and ionomer resins obtained by crosslinking ethylene-acrylic acid copolymers commercially available under trade names such as Surlyn with metals such as sodium and zinc.

、アルミニウム箔にウレタン等の接着剤によりドライラ
ミネーションで積層しても良い。This resin may be directly extrusion coated onto aluminum foil, or more efficiently, the resin may be made into a film and then laminated onto aluminum foil by dry lamination using an adhesive such as urethane.

が良い、一方、１５０ＬＬｍ以上とする場合にはヒート
シール上、特に問題はないが高価な樹脂の損失となるだ
けであるので、この程度が上限と考えている。In this case, the thickness of the resin layer is about 30 um to 150 um, preferably about 50 to 80 LLm. When making it thinner than 30um, there is a risk that heat sealing will be insufficient when the line speed is increased, so it is better to make it thicker than this.On the other hand, when making it thicker than 150LLm, there is no particular problem with heat sealing. This level is considered to be the upper limit since it will only result in a loss of expensive resin.
アルミニウム箔の厚みは内容物の種類、ガラス容器の口

ｌｏｏｕｍ〜２５０μｍ程度である。炭酸水のごとき内
圧がかかるもの以外であれば約１５０ｕｒｎ近辺の厚み
で強度的には充分である。Although the thickness of the aluminum foil varies depending on the type of contents, the diameter and purpose of the glass container, it is 50 LLm or more, usually about louum to 250 μm. For applications other than those subject to internal pressure such as carbonated water, a thickness around 150 urns is sufficient for strength.
なお、アルミニウム箔へガラス接着性樹脂を接着した面
は本明細書では内側といい、この面がガラス容器の口へ
接することになる。Note that the surface on which the glass-adhesive resin is adhered to the aluminum foil is referred to as the inside in this specification, and this surface comes into contact with the mouth of the glass container.
アルミニウム箔の他の面はオーバーコートとして、印刷
および印刷の保護のためのオーバーコートが施されてい

する。Note that this cap material is made into a laminate by laminating aluminum foil, then punched into the shape of a cap for a wide-mouthed glass container, and subjected to processes such as molding to obtain a cap material.
一方、ガラス容器は内容物の充填工程を出た所で前記キ

Since this is a combination of heat sealing and clipping, the heat sealing part is protected from pressure due to clipping, and the sealing degree is high and complete.

In addition, since the material is aluminum foil, which has excellent workability, it prints beautifully, is easy to manufacture, and speeds up the sealing line, and is a cap material that causes fewer troubles. In addition, a two-stage sealing method of clipping and heat sealing is used, and the completeness of the seal by heat sealing is complemented by clipping, which significantly strengthens the resistance to mechanical strength, which is a drawback of heat sealing. has been done.

である。Compared to conventional tear-off caps, which are the main type of sealing method by clipping, there is no need for separate sealants such as expensive plastisol compounds or backings, and the inner surface is entirely dry laminated and made of synthetic resin that adheres to glass. Since it is coated, there is no need for a corrosion-resistant coating, which leads to cost reduction and is extremely excellent.

可能である。If you put a tab on the cap, put a score vertically on the skirt part next to the tab like a pull-up cap, and put a score on the center line of the cap, it will be easier to open than a conventional tear-off cap. It is also possible to design it so that it can be done.
