包装体用シートに関する。[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to a lid material for sealing a container body made of paper, plastics, glass, ceramics, etc. by heat sealing, and a lid material for sealing a container body made of paper, plastics, glass, ceramics, etc. The present invention relates to a packaging sheet for manufacturing containers such as bags made of such materials. In particular, the present invention relates to a packaging sheet having a double structure of an outer layer and an inner layer, the outer layer of which can be peeled off by hand.
外層材と内層材から成り、外層材を剥離するようにした
二重構造蓋材における剥離開始部の形成方法として、次
のことが提案されている。The following method has been proposed as a method for forming a peeling start part in a double-structured lid material that is composed of an outer layer material and an inner layer material and in which the outer layer material is peeled off.

き、その部分より剥離することが開示され（第５図）、
マた実開昭６２−８０８６２号公報には、剥離開始部を
接着させないことが開示されている（第１図）が、各々
次のような欠点がある。For example, Japanese Utility Model Application Publication No. 61-12726 discloses the use of a weak adhesive that is easily peeled off with normal force when pinched with fingertips and pulled.
Publication No. 825 discloses that the inner layer material (base material layer) is cut and peeled from that part (Fig. 5),
Matami Kokai Publication No. 62-80862 discloses that the peeling starting part is not bonded (FIG. 1), but each method has the following drawbacks.
まず最初のものは、一般消費者が使用する時に、剥離開
始部が２枚に分かれていないため、誤開封する率が高く
、また、使用時に剥離開始部を作る必要があり、煩わし
い。First of all, when used by general consumers, the peeling start part is not divided into two sheets, so there is a high chance of accidental opening, and the peeling start part needs to be created at the time of use, which is cumbersome.
第２の方法は、外層材を剥離する際は良いが、内層材を
剥離する際のタブがなくなり、不都合である。The second method is good for peeling off the outer layer material, but is inconvenient because it eliminates the tab when peeling off the inner layer material.
最後のものは、蓋材を形成する長尺材の長手方向と平行
にしか剥離開始部を設けることができず、材料ロスが大
きく、コスト高となる。In the last method, the peeling start portion can only be provided in parallel to the longitudinal direction of the elongated material forming the lid, resulting in large material loss and high cost.
そこで、この発明の課題は、剥離開始部を容易に識別す
ることができ、また剥離開始部を使用者が作る必要もな
く、外層を剥離しても内層材のタブが残存するようにし
た包装体用シートを提供することである。Therefore, an object of this invention is to provide a package in which the peeling starting part can be easily identified, the user does not need to create the peeling starting part, and the tab of the inner layer material remains even when the outer layer is peeled off. The purpose of the present invention is to provide a body sheet.
上記の課題を解決するため、この発明は、外層材と内層
材を手で容易に剥離可能な接着層によって積層した包装
体用シートにおいて、前記外層材と内層材の少くとも一
方に二軸延伸ナイロンフィルムを使用し、かつ剥離開始
部において、外層材と内層材の接着強度を他の部分より
弱くした構成を採用したのである。In order to solve the above problems, the present invention provides a packaging sheet in which an outer layer material and an inner layer material are laminated by an adhesive layer that can be easily peeled off by hand, and in which at least one of the outer layer material and the inner layer material is biaxially stretched. A structure was adopted in which a nylon film was used and the adhesive strength between the outer layer material and the inner layer material was weaker at the peeling initiation part than at other parts.
上記のように、剥離開始部においては外層材と内層材と

のような処理工程が無い場合には、熱風等を当ててやれ
ばよい。As mentioned above, the adhesive strength between the outer layer material and the inner layer material is made weaker in the peeling starting part than in other parts, and a biaxially stretched nylon film is used for at least one of the outer layer material and the inner layer material. Therefore, by applying heat to the peeling starting part, the biaxially stretched film contracts, and the peeling starting part is divided into two sheets. The method of applying heat is automatically carried out if, for example, boiling or retort treatment is included in the product manufacturing process, and if there is no such treatment process, hot air or the like may be applied.
まず、蓋材を例にとって、この発明の実施例について説
明する。First, embodiments of the present invention will be described using a lid material as an example.
第１図に示すように、蓋材１は外層材２及び内層材３を

設けてもよい。As shown in Fig. 1, the lid material 1 is made by laminating an outer layer material 2 and an inner layer material 3 using an adhesive layer 4 that can be easily peeled off by hand. An adhesive weakening layer 5 is provided to weaken the adhesive. Alternatively, as shown in FIG. 2, the adhesion reinforcing layer 6 may be provided at a location other than the peeling initiation portion.

えたり、接着層４の接着剤の種類を変えるなどである。Furthermore, although not shown in the drawings, a method for providing the weakened adhesion layer 5 and the strengthened adhesion layer 6, which may be used in combination with the layers 5 and 6, is as follows.
For example, the height of the heat-sealing hot plate may be changed to change the pressing force, or the type of adhesive for the adhesive layer 4 may be changed.

ムにすればよい。The inner layer material 3 is made of polyester, as shown in FIG.
A heat-sealing layer 32 is provided on the outer surface of a base sheet 31 made of nylon (trade name), polypropylene, paper, etc., but if the base sheet 31 has heat-sealing properties, the layer 32 can be omitted. Note that if the outer layer material 2 is not a biaxially stretched nylon film, the base sheet 31 may be a biaxially stretched nylon film.
また、第６図に示すように、ベースシート３１に接着剤
３３を介して、金属箔や金属蒸着フィルムのような金属
薄膜３４を積層し、その外面にヒートシール層３２を設
けてもよい。Alternatively, as shown in FIG. 6, a metal thin film 34 such as metal foil or metallized film may be laminated on the base sheet 31 via an adhesive 33, and a heat seal layer 32 may be provided on the outer surface of the metal thin film 34.
上述のような蓋材１を用いて、密封容器を形成した例を
第７図に示す。FIG. 7 shows an example in which a sealed container is formed using the lid material 1 as described above.
図示のように容器本体４０の開口部には、フランジ４１

４２は、剥離開始部である。As shown in the figure, a flange 41 is provided at the opening of the container body 40.
is provided on the top surface of the flange 41, and the lid material 1
are heat sealed to form a sealed container. In the figure,
42 is a peeling start part.
上記剥離開始部４２は、密封容器形成後、加熱により外
層材２に含まれる二軸延伸ナイロンフィルムが収縮し、
内層材３と反対方向にカールすることにより形成されて
いる。The peeling starting part 42 is formed by shrinking the biaxially stretched nylon film contained in the outer layer material 2 by heating after forming the sealed container.
It is formed by curling in the opposite direction to the inner layer material 3.
上記密封容器を開封するには、剥離開始部４２において

離する時は、やはり剥離開始部４２において、内層材３
をつまんで剥がせばよい。なお、容器の形状は円形、角
形等いずれでもよい。To unseal the sealed container, the outer layer material 2 is pinched and pulled upward at the peeling start section 42, and then it is peeled off from the inner layer material 3. When peeling the inner layer material 3 from the container body 40, the inner layer material 3 is also removed at the peeling start part 42.
Just pinch it and peel it off. Note that the shape of the container may be circular, square, or the like.
また、前記蓋材１と同じ構成の包装体用シートを用い袋
を製作することはもちろん容易であり、同様の効果が得

さらに、剥離開始部において、外層材と内層材を印刷等
によって色分けしておくと識別が容易である。Furthermore, if the outer layer material and the inner layer material are color-coded by printing or the like at the peeling start portion, they can be easily identified.
