2. Description of the Related Art Peel containers, in which a container body and a top film serving as a lid are bonded and sealed by heat fusion or the like at a flange portion, are widely used as containers for dessert foods and the like. In this case, if the container body and the top film are well sealed, it is not easy to peel them off by hand.

That is, the simple peel container of the present invention is a peel container consisting of a container body formed of a multilayer sheet and a top film bonded to the flange portion of the container body. The container is constructed such that the adhesive strength is smaller than the adhesive force between the flange portion and the top film, and cuts are provided in the inner layer of the flange portion on the side of the container opening and the outer layer on the side of the container periphery.
以下本発明を図面に基づいて説明する。第１図
は本発明の一実施例を部分断面図である。 The present invention will be explained below based on the drawings. FIG. 1 is a partial sectional view of an embodiment of the present invention.
Ａは通常共押出シート等からなる多層シートで
真空成形、圧空成形等により容器本体１を形成し
ている。容器本体には容器の蓋となるトツプフイ
ルムＢを接着するためのフランジ部２が設けられ
ている。 A is usually a multilayer sheet made of a coextruded sheet, etc., and the container body 1 is formed by vacuum forming, pressure forming, etc. The container body is provided with a flange portion 2 to which a top film B serving as a lid of the container is adhered.
トツプフイルムＢは図では２層フイルムとなつ
ているが、単層フイルムであつても多層フイルム
であつてもいずれでもよく、とくに制限はない。 Although the top film B is a two-layer film in the figure, it may be a single-layer film or a multi-layer film, and is not particularly limited.

とからなつている。表面素材にシーラントと同様
な材料を使用すれば、トツプフイルムは前述した
ように単層フイルムも使用できる。 In the case of using a two-layer film, the surface base material 3 is made of a plastic single-layer film, multi-layer film, paper, aluminum foil, or a composite material thereof, and polyethylene, polypropylene, or ethylene-α-olefin copolymer. Sealant 4 made of , ethylene-vinyl acetate copolymer, etc.
It is made up of. If a material similar to a sealant is used for the surface material, a single layer top film can also be used as the top film as described above.

外層は単一層でも、あるいはガスバリアー性樹脂
層などを含む多層でもいずれでもよい。 There are no particular restrictions on the material of the multilayer container for the inner layer, and the material that has good heat sealing properties with the sealant layer of the top film may be the same or similar resin as the sealant layer. The material may be selected as appropriate in consideration of the purpose, heat resistance, rigidity, etc., and for example, polypropylene, polyester, polystyrene, or a resin containing these with an inorganic filler may be used.
The outer layer may be a single layer or a multilayer including a gas barrier resin layer.
内層の厚みについては、容器の強度は外層で保
てばよく、内層は内容物の保護ができればよいの
で薄くすることができる。 Regarding the thickness of the inner layer, it is sufficient that the strength of the container is maintained by the outer layer, and the inner layer only needs to be able to protect the contents, so it can be made thin.
多層容器の内層と外層は適度の接着性を有する
素材が組み合わされ、その層間接着力は通常、剥
離強度1.5Kg／15mm以下（引張速度300mm／min）
とするのが好ましい。 The inner and outer layers of multilayer containers are made of materials with moderate adhesive properties, and the interlayer adhesive strength is usually less than 1.5 kg/15 mm in peel strength (pulling speed 300 mm/min).
It is preferable that

常２Kg／15mm以上、さらに好ましくは４Kg／15mm
以上とするのがよい。 The inner layer of the multilayer container and the top film are heat-sealed at the sealing portion 9 of the flange portion of the container body.
It is fused by ultrasonic sealing etc., and its peel strength should be greater than the interlayer peel strength of the container, usually 2 kg/15 mm or more, more preferably 4 kg/15 mm.
It is better to set it to the above.
容器本体のフランジ部の内層の開口部側には周

まに剥がすような場合は、そこの部分だけ切り込
みを入れないようにする。 A circumferential cut 7 is made on the opening side of the inner layer of the flange portion of the container body. The incisions are usually made by a pressing mold with a circumferential blade, and it is sufficient that the inner layer can be easily cut when the lid is peeled off. Good too. Further, the notch may be made all around the circumference, or a portion may be left. If you are removing the top film with part of it still attached, make sure not to cut that part.

みをつけずに残しておいてもよい。 A notch 8 is made on the peripheral edge side of the outer layer of the flange portion of the multilayer container. The notch may be provided by a mold when molding the container body, or,
After forming the container body, when fusing the top film or punching out the container body and the top film, it is provided with a press die having a circumferential blade, etc.
The shape and formation method are not particularly limited as long as the outer layer can be separated and the inner and outer layers can be easily peeled off. In addition, if the position of the cut in the outer layer is closer to the periphery of the flange than the cut in the inner layer, the peeling of the inner and outer layers will be easier and the purpose will be achieved, but considering the strength of the container body, it is difficult to break the outer layer with your fingers It is preferable to provide the flange part as close to the peripheral edge of the flange part as possible, leaving a grip part for the fingers to be used when separating the flange part. Further, similar to the cuts in the inner layer, these cuts may be made all around the circumference, or a portion may be left uncut.
本発明の容器の形状はカツプ状のものに限定さ
れず、箱状、皿状、その他種々の形状が可能であ
る。 The shape of the container of the present invention is not limited to a cup shape, but can be box-shaped, dish-shaped, and various other shapes.

単な動作で容易に開封することができる。
When a product is sealed in the container of the present invention and a top film is attached, the product can be easily opened by the following simple operations.

てもイージーピールが可能となる。 For example, in FIG. 1, the peripheral edge of the flange portion 2 is lifted upward. Then the outer layer has a cut 8
The inner layer 5 of the container body is separated into two parts at the position .
Peeling occurs between the outer layer 6 and the outer layer 6, and the peeling between the inner and outer layers progresses to the notch 7. After reaching the notch 7, only the top film B is peeled off (see FIG. 2). Therefore, even if the top film and the flange portion of the container body are firmly adhered to each other, easy peeling is possible.
以下、本発明を実施例に基づいて詳細に説明す
るが、本発明はこれに限定されるものではない。
Hereinafter, the present invention will be explained in detail based on Examples, but the present invention is not limited thereto.
多層シートより圧空成形により開口部径60mm、

おフランジ部内層は高密度ポリエチレン50μ、外
層はエチレン−プロピレン−ラバー10重量％配合
ポリプロピレンであつた。 Opening diameter is 60mm by pressure forming from multilayer sheet.
A container body with a bottom diameter of 50 mm and a height of 25 mm was molded. The inner layer of the flange portion was made of 50 μm high-density polyethylene, and the outer layer was made of polypropylene containing 10% by weight of ethylene-propylene-rubber.
この容器フランジ部の内層および外層にリング
状の切り込みをほぼ層間に達するように設けた。 Ring-shaped cuts were provided in the inner and outer layers of the container flange portion so as to reach approximately between the layers.

つた。 Next, a multilayer film (PET/EVOH/LLDPE: 12μ/20μ/30μ) was used as the top film.
The illustrated portion was heat-sealed using LLDPE as a sealing surface to obtain a simple peel container. When the flange of this container was folded at the notch in the outer layer and peeled, peeling started between the layers of the container body, and after reaching the notch in the inner layer, the top film and the container body began to peel, causing a peeling sensation. It was also good.
