<蓋(4)>
蓋(4)は、内容物(3)を収容した成形容器(1)の開口(11)周縁に熱融着させられる部材であり、所定のラミネート包材で構成される。
ラミネート包材は、例えば、所定の保護樹脂層、金属箔層、強化層、及び熱融着性樹脂層をこの順番で積層したものである(図示略)。ただし、金属箔層と強化層はいずれも任意であり、省略できる。
保護樹脂層は、蓋(4)の最外面を形成する層であり、各種公知の合成樹脂を特に制限なく使用できる。具体的には、例えば、延伸ポリエチレンテレフタレート、延伸ポリアミド及び延伸ポリプロピレン等の延伸フィルムが挙げられる。保護樹脂層は、同一又は異なる合成樹脂を任意の順序で一又は二以上組み合わせた複層あってもよい。保護樹脂層は前記オーバーコート剤で構成してもよい。保護樹脂層の厚みは特に制限されず、包装体(5)の耐久性や耐衝撃性、耐候性等の観点より、通常1～30μm、好ましくは2～25μmである。
任意の金属箔層は、成形容器(1)に収容する内容物(3)を、ガス、水蒸気及び光等から保護するためのバリア層として機能する。金属箔としては前記したものや、アルミニウム硬質箔(H18材)を使用できる。金属箔層の片面又は両面には前記下地層を形成してもよい。金属箔層の厚みは特に制限されず、水分、ガス及び光のバリア性やシール性の観点より、通常5～40μmである。
任意の強化層は、各種公知の合成樹脂で構成されており、金属箔層と熱融着性樹脂層との間に介在させることで、蓋(4)の強度を向上できる。該合成樹脂としては、例えば、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレン、ポリプロピレン及び二軸延伸ナイロン等が挙げられる。強化層の厚みは特に制限されず、包装体(5)の耐久性や耐衝撃性等の観点より通常5～30μmである。

ラミネート包材は、例えばドライラミネート法や押し出しラミネート法、ヒートラミネート法などで作製できる。ドライラミネート法の場合には前記接着剤を使用できる。ラミネート包材を所望の形状に加工することにより蓋(4)が得られる。蓋(4)の形状は特に限定されず、例えば、成形容器(1)のフランジ部(12)と同形又は相似形であればよい。
蓋(4)には、任意に開封用タブ(41)を設けてよい。開封用タブ(41)の大きさや形状は特に限定されず、例えば半円形や三角形、四角形であってよい。
<Lid (4)>
The lid (4) is a member heat-sealed to the periphery of the opening (11) of the molded container (1) containing the contents (3), and is made of a predetermined laminated packaging material .
The laminated packaging material is obtained by laminating a predetermined protective resin layer, a metal foil layer, a reinforcing layer, and a heat-fusible resin layer in this order, for example (not shown). However, both the metal foil layer and the reinforcing layer are optional and can be omitted.
The protective resin layer is a layer forming the outermost surface of the lid (4), and various known synthetic resins can be used without particular limitations. Specific examples include stretched films such as stretched polyethylene terephthalate, stretched polyamide and stretched polypropylene. The protective resin layer may have multiple layers in which one or more of the same or different synthetic resins are combined in any order. The protective resin layer may be composed of the overcoat agent. The thickness of the protective resin layer is not particularly limited, and is usually 1 to 30 μm, preferably 2 to 25 μm, from the viewpoint of durability, impact resistance, weather resistance, etc. of the package (5).
The optional metal foil layer functions as a barrier layer to protect the contents (3) contained in the molded container (1) from gases, water vapor, light and the like. As the metal foil, the above-mentioned one or aluminum hard foil (H18 material) can be used. The base layer may be formed on one side or both sides of the metal foil layer . The thickness of the metal foil layer is not particularly limited, and is usually 5 to 40 μm from the viewpoint of moisture, gas and light barrier properties and sealing properties.
The optional reinforcing layer is composed of various known synthetic resins, and can improve the strength of the lid (4) by interposing it between the metal foil layer and the heat-sealable resin layer . Examples of the synthetic resin include polyethylene terephthalate, polybutylene terephthalate, polyethylene, polypropylene and biaxially oriented nylon. The thickness of the reinforcing layer is not particularly limited, and is usually 5 to 30 μm from the viewpoint of durability, impact resistance, etc. of the package (5).
The heat-fusible resin layer is a layer heat-sealed to the colored heat-fusible resin layer (10a) forming the upper surface of the flange portion (12) of the molded container (1), and is made of various known thermoplastic resins. can be configured with Specifically, for example, homopolypropylene, poly(ethylene-propylene) random copolymer, polyethylene-polypropylene block copolymer, acid-modified polypropylene, low-density polyethylene, linear low-density polyethylene, polyvinyl alcohol, ionomer resin and Examples include acrylic copolymer resins. The thickness of the heat-fusible resin layer is not particularly limited, and is usually 10-100 μm.
A laminate packaging material can be produced by, for example, a dry lamination method, an extrusion lamination method, a heat lamination method, or the like. The above adhesives can be used in the case of the dry lamination method. A lid (4) is obtained by processing the laminated packaging material into a desired shape. The shape of the lid (4) is not particularly limited, and may be, for example, the same shape or a similar shape to the flange portion (12) of the molded container (1).
The lid (4) may optionally be provided with an opening tab (41). The size and shape of the opening tab (41) are not particularly limited, and may be semicircular, triangular, or quadrangular, for example.
