【考案の詳細な説明】 本考案は易開封性ガラス包装体に関する。[Detailed explanation of the idea] The present invention relates to an easy-open glass package.
今日、プラスチツク容器が軽さ、こわれにく
さ、成型性等の利点から広く使用されるようにな
つたが、ガラス容器の持つ衛生性、高級感等まだ
まだプラスチツク容器の侵すことのできない分野
が多い。しかし、ガラスに対する接着技術が確立
されていないため、密閉形態に種々の制約があ
り、包装材料としての多様性に乏しい。現在、密
閉形態としては、大きく分けて次の４つがある。 Nowadays, plastic containers are widely used due to their advantages such as lightness, resistance to breakage, and moldability, but there are still many areas where plastic containers cannot compete, such as the sanitary and luxurious feel of glass containers. However, since the adhesion technology for glass has not been established, there are various restrictions on the sealing form, and there is a lack of versatility as a packaging material. Currently, there are four main types of closed systems:
ねじこみ式金属キヤツプで密閉するタイプ
（例、ジヤム、そう菜、マヨネーズなど）
アルミ蓋でフランジ部を抱きこむように絞つ
て、さらに上からプラスチツク蓋で押えこんで

（例、ワンカツプタイプの酒及びジユース、
フルーツソース、ふりかけなど）
水性のり、ワツクス等接着剤で蓋と容器を接
着し、さらに上からプラスチツク蓋をするタイ

（例、インスタントコーヒー、だしの素な

金属栓をするタイプ
（例、ビール、酢、ジユースなど）
而して、上記，，及びのタイプのものは
現在の方法で充分に密閉の目的が達せられている
ものであるが、しかし、のタイプについてはほ

ある。このため、ガラス容器の持つ重要な特徴で
ある衛生性が半減していると言わざるを得ず、仮
にシールされうる中蓋が存在すれば、バージンシ
ールによる安心感は、はかり知れないものであ
る。 Types that are sealed with screw-on metal caps (e.g. jams, greens, mayonnaise, etc.) Types that have an aluminum lid that wraps around the flange and are then covered with a plastic lid (e.g. one-cup type sake) and the use,
(fruit sauce, furikake, etc.) A type in which the lid and container are glued together with an adhesive such as water-based glue or wax, and then a plastic lid on top (e.g., instant coffee, dashi base, etc.) A type in which a metal stopper is attached (e.g., beer, etc.) (vinegar, juice, etc.) The above types, , and can be sufficiently sealed with the current methods; however, most of the types have no inner lid. When the screw-on metal cap is opened, the contents can be accessed directly. Furthermore, these products are naturally displayed at stores such as markets, and anyone can open and close the lids and display them. For this reason, it must be said that hygiene, which is an important characteristic of glass containers, has been halved, and if there was an inner lid that could be sealed, the sense of security that a virgin seal would provide would be immeasurable. .

行処理方法では使用用途に限界がある。 Regarding this type, since it has an aluminum lid, there is a risk of accidentally cutting your hand when opening it, so if it were possible to change to a general lid material specification made of composite materials such as PET/Al/sealant. ,
The above-mentioned risks are eliminated and cost benefits are also obtained. Furthermore, it is difficult to remove the type using the current water-based glue, and the appearance after removal is extremely dirty. Furthermore, there are limits to how wax can be used with current processing methods.

問題点がある。 Furthermore, Japanese Patent Publication No. 61-9181 states that in the glass container manufacturing process, titanium tetrachloride is applied to the open end surface of the glass container immediately after leaving the molding station, that is, at the high temperature end, at a temperature of about 300 to 600°C. A glass container for a sealed package is disclosed in which a thermoplastic resin layer is formed on the open end surface of the glass container which has a coating layer of titanium oxide formed by spraying. However, the titanium oxide coating layer formed by this method has poor adhesion with the thermoplastic resin layer that is the sealant layer, and therefore it is difficult to provide a sealant layer with stable adhesive strength on the glass surface. There is a problem to be said.

とづいて本考案を完成したものである。 As a result of research to eliminate the above-mentioned drawbacks, the inventor of the present invention has found that a sealant made of an ethylene vinyl acetate copolymer wax or a combination of a sealant containing an ethylene vinyl acetate copolymer wax as one component and a polyolefin sealant provides a good and easy-to-use sealant. It is possible to form a seal that shows openness, and by providing a sealant layer on the glass surface via a titanium oxide film formed by hydrolyzing an alkyl titanate coating solution, it is possible to maintain stable adhesive strength on the glass surface. It was discovered that a sealant layer could be provided, and the present invention was completed based on this knowledge.

A sealant layer made of wax or a sealant layer containing ethylene vinyl acetate copolymer wax as one component is provided, and a polyolefin sealant layer is provided for the lid material, and the lid material is placed over the mouth of the glass container body and heat sealed. This is an easy-to-open glass package characterized by:
以下、本考案につき図面を参照しながら詳細に
説明する。 Hereinafter, the present invention will be described in detail with reference to the drawings.

A sealant layer consisting of an ethylene vinyl acetate copolymer wax or a sealant layer containing an ethylene vinyl acetate copolymer wax as one component is applied to the area to be bonded to the titanium oxide film 3 formed by hydrolyzing an alkyl titanate coating solution. 4
On the other hand, a polyolefin sealant layer 8 is provided on the lower surface of the base material of the lid material 9 made of polyester film 5 and aluminum foil 6, and a lid material 9 is provided on the mouth of the glass container body 2 filled with the contents 2.
is covered and heat sealed.

得る。 In the present invention, the titanium oxide coating is treated with TPT (tetraisopropyl titanate) and TBT (tetra n-
A titanium oxide film formed on the glass surface by heating and drying after applying a thin layer of alkyl titanate solution made by dissolving single substances or blends of TST (tetrastearyl titanate) and TST (tetrastearyl titanate) in a solvent such as hexane or toluene. applicable.
このようにして形成した酸化チタン被膜中に
は、有機物が残存していることと、加水分解の際
に水やアルコールが抜けていくので、酸化チタン
被膜がポーラスになることによつてガラス面上に
充分な接着強度でシーラント層を設けることがで
きる。 In the titanium oxide film formed in this way, organic substances remain and water and alcohol escape during hydrolysis, so the titanium oxide film becomes porous and forms a surface layer on the glass surface. A sealant layer can be provided with sufficient adhesive strength.
アルキルチタネート溶液はできるだけ薄膜に、
均一にむらなく塗布できるように１〜３％に希釈
したものを用いるのが好ましく、１％以下のとき
は塗布量が少ないが故に均一に塗布することがで
きず、一方３％以上のときはひびわれ等が生じや
すいので好ましくない。 The alkyl titanate solution should be made into a thin film as much as possible.
It is preferable to use a diluted product of 1 to 3% so that it can be applied uniformly and evenly; if it is less than 1%, the amount of application is small and it will not be possible to apply it evenly, whereas if it is more than 3%, it will not be possible to apply it evenly. This is not preferred as it tends to cause cracks etc.
次にアルキルチタネート溶液塗布後の加熱温度
は50〜100℃が好ましく、前記温度範囲以外では
酸化チタン皮膜とガラス間の接着不良をおこし易
い。 Next, the heating temperature after applying the alkyl titanate solution is preferably 50 to 100°C; temperatures outside the above range tend to cause poor adhesion between the titanium oxide film and the glass.
次に加熱乾燥の時間は10秒ないし240秒が好ま

間の接着が不安定になるので好ましくなく、一
方、240秒以上になると酸化チタン皮膜とガラス
間の接着力が平衡に達し、これ以上の熱処理は不
要である。 Next, the heating drying time is preferably 10 seconds to 240 seconds. If it is less than 10 seconds, the adhesion between the titanium oxide film and the glass will become unstable, which is undesirable. On the other hand, if it is more than 240 seconds, the adhesive force between the titanium oxide film and the glass will reach equilibrium, and no further heat treatment is required. It is.

強度低下は見られない。 In the package of the present invention, the titanium oxide film is interposed between the glass and the sealant layer, making it possible to provide the sealant layer on the glass surface with stable adhesive strength, and the interface between the glass and the titanium oxide film is Since it prevents water from entering, there is no decrease in strength due to the influence of water, and no decrease in strength is observed even after being stored in water for one week.

It is possible to give consumers the sense of security that a virgin seal provides. Furthermore, since the package of the present invention has good easy-opening properties, there is no risk of accidentally cutting one's hand when opening the package, unlike the above-mentioned types. Furthermore, in the package of the present invention, there is no dirt on the flange after peeling off the lid material, and
Can also be used with humid contents.
