【考案の詳細な説明】
この考案は、プレススルーパツクの裏貼りシー
トに関する。[Detailed description of the invention] This invention relates to a backing sheet for a press-through pack.
プレススルーパツクは、第２図に示すように、
収納体１に多数のポケツト部２を設け、この中に
錠剤Ｔなどを収納し、ポケツト部２の外側に裏貼
りシート１０を接着して密封したものであつて、
開封する場合には、ポケツト部２の外側から指で
押圧して、錠剤Ｔで裏貼りシート１０を突き破
り、錠剤を取り出すようにしてある。 The press-through pack, as shown in Figure 2,
A storage body 1 is provided with a large number of pockets 2, in which tablets T, etc. are stored, and a backing sheet 10 is adhered to the outside of the pockets 2 to seal them.
When opening the package, the tablet T is pressed with a finger from the outside of the pocket part 2 to pierce the backing sheet 10 and take out the tablet.
ところで、このような裏貼りシート１０は、通
常厚さ20μ程度のアルミニウム箔を基材として、
その一面にヒートシール層を設け、他面に印刷層
及び表面樹脂層を設けたものであるが、この印刷
層は、通常アルミニウム箔の艶面に形成されてい
るので、艶面の高反射性によつて印刷された文
字、図形などが極めて判読し難くなる欠点があ
る。 By the way, such a backing sheet 10 is usually made of aluminum foil with a thickness of about 20 μm as a base material.
A heat-sealing layer is provided on one side, and a printing layer and a surface resin layer are provided on the other side, but since this printing layer is usually formed on the glossy surface of aluminum foil, the glossy surface has high reflectivity. This has the disadvantage that characters, figures, etc. printed by this method are extremely difficult to read.
この考案は、上記の欠点を解消し、アルミニウ
ム箔に印刷された文字などが明瞭に観取できるよ
うにした裏貼りシートを提供することが目的であ
る。 The purpose of this invention is to provide a backing sheet that eliminates the above-mentioned drawbacks and allows characters printed on aluminum foil to be clearly seen.
上記の目的を達成するため、この考案において
は、表面樹脂層を形成する樹脂中に、平均粒径が
１〜10μの充填剤を樹脂分に対して５重量％を超
え15重量％以下の割合で混入したのである。 In order to achieve the above purpose, in this invention, a filler with an average particle size of 1 to 10μ is added to the resin forming the surface resin layer in a proportion of more than 5% by weight and less than 15% by weight based on the resin content. It was mixed in.
このような充填剤を混入することによつて、表
面樹脂層表面に現れた微細な凹凸や充填剤そのも
のにより、入射光、反射光共に散乱させることが
できるので、アルミニウム箔の艶面に印刷された
文字等を明瞭に観取することができるようになる
のである。 By incorporating such a filler, both incident light and reflected light can be scattered by the fine irregularities that appear on the surface of the surface resin layer and the filler itself, so it is possible to scatter both incident and reflected light. This makes it possible to clearly see written characters, etc.
以下、この考案の実施例を添付図面に基いて説
明する。 Embodiments of this invention will be described below with reference to the accompanying drawings.
第１図に示すように、裏貼りシート１０は、ア
ルミニウム箔１１の一面にヒートシール層１２、
艶面である他面に印刷層１３及び表面樹脂層１４
を設けたものである。 As shown in FIG. 1, the backing sheet 10 includes a heat seal layer 12 on one side of an aluminum foil 11,
Print layer 13 and surface resin layer 14 on the other glossy surface
It has been established.
上記アルミニウム箔１１は、硬質、軟質いずれ
でもよいが、内容物の保護及びそれを取り出す際
の突き破り性からみて15〜30μの厚みが望まし
い。即ち、15μ以下ではピンホールが生じ易く、
30μを越えると突き破り性が悪くなるからであ
る。 The aluminum foil 11 may be either hard or soft, but a thickness of 15 to 30 μm is desirable in terms of protection of the contents and breakability when taking out the contents. In other words, if the thickness is less than 15μ, pinholes are likely to occur.
This is because if the thickness exceeds 30 μ, the penetration property deteriorates.
上記ヒートシール層１２は、ビニル系樹脂とし
ては塩化ビニル、塩化ビニル−酢酸ビニル系共重
合体、ポリプロピレン系樹脂としては塩素化ポリ
プロピレン、カルボキシル化ポリプロピレン又は
これらの混合樹脂等を主成分とする樹脂等、通常
の熱可塑性接着剤から成つている。 The heat seal layer 12 is made of a resin whose main component is vinyl chloride, vinyl chloride-vinyl acetate copolymer as the vinyl resin, and chlorinated polypropylene, carboxylated polypropylene, or a mixed resin thereof as the polypropylene resin. , usually made of thermoplastic adhesive.
上記表面樹脂層１４は、例えばニトロセルロー
ス、アクリル樹脂、エポキシ樹脂又はこれらの混
合樹脂などを主成分にし、これに平均粒径が１〜
10μの充填剤を５重量％を超え15重量％以下、好
ましくは５重量％を超え10重量％以下の割合で混
入したものである。この充填剤としては、酸化硅
素、珪酸マグネシウム、珪藻土、二酸化チタン、
亜鉛華、炭酸カルシウム、アルミナホワイト、タ
ルクなどが例示できるが、これに限らない。また
着色顔料を併せて用いることもできる。 The surface resin layer 14 is mainly composed of, for example, nitrocellulose, acrylic resin, epoxy resin, or a mixed resin thereof, and has particles having an average particle size of 1 to 1.
A filler of 10μ is mixed in a proportion of more than 5% by weight and less than 15% by weight, preferably more than 5% by weight and less than 10% by weight. These fillers include silicon oxide, magnesium silicate, diatomaceous earth, titanium dioxide,
Examples include, but are not limited to, zinc white, calcium carbonate, alumina white, and talc. Moreover, a colored pigment can also be used in combination.
上記充填剤の平均粒径は、1μより小さいと艶
消し効果が充分ではなく、10μより大きいと樹脂
層１４の表面の凹凸が大きすぎて滑り性が悪くな
り、プレススルーパツクの製造工程中の作業性に
問題が生じる。 If the average particle size of the filler is smaller than 1μ, the matting effect will not be sufficient, and if it is larger than 10μ, the surface of the resin layer 14 will be too uneven, resulting in poor slipperiness, which may cause problems during the press-through pack manufacturing process. Problems arise in workability.
また、混入量は、平均粒子径の大きさと樹脂層
の厚さにもよるが、５重量％以下では艶消し感が
十分でない場合があり、15重量％よりも多いと樹
脂層表面の粗さが目立つようになり好ましくな
い。 In addition, the amount mixed depends on the size of the average particle size and the thickness of the resin layer, but if it is less than 5% by weight, the matte feeling may not be sufficient, and if it is more than 15% by weight, the surface roughness of the resin layer may occur. becomes noticeable and is not desirable.
さらに、樹脂層１４の表面滑り性をよくするた
め低分子ポリエチレンワツクスなどの添加剤を混
入したり、メラミンなどの硬化剤を加えることが
できる。このようにして、充填剤などを混入した
樹脂を２〜10ｇ／m2好ましくは２〜６ｇ／m2塗布
することにより表面樹脂層１４を形成する。この
場合、塗布量が２ｇ／m2以下であると、充填剤の
混入量からして、樹脂層表面が粗くなり過ぎ、10
ｇ／m2以上塗布してもさほど効果をあげることが
できない。 Further, in order to improve the surface slipperiness of the resin layer 14, additives such as low molecular weight polyethylene wax or the like or a hardening agent such as melamine may be added. In this manner, the surface resin layer 14 is formed by applying 2 to 10 g/m 2 , preferably 2 to 6 g/m 2 of the resin mixed with fillers and the like. In this case, if the coating amount is less than 2g/ m2 , the surface of the resin layer will become too rough considering the amount of filler mixed in.
Even if it is applied in excess of g/ m2 , it will not be very effective.
なお、第３図に示すように、まずアルミニウム
箔１１に表面樹脂層１４を形成した後、印刷層１
３を設けてもよい。 Incidentally, as shown in FIG. 3, after first forming the surface resin layer 14 on the aluminum foil 11, the printing layer 1
3 may be provided.
この考案によれば、以上のように、表面樹脂層
を形成する樹脂中に細い粒子から成る充填剤を混
入したので、この層の表面に細い凹凸が現れて乱
反射を起こさせ、さらに光を吸収するので、その
面が艶消しになつて、基材のアルミニウム箔の艶
面による高反射を抑制し、印刷された文字等が非
常に見易くなる効果がある。 According to this invention, as described above, a filler consisting of thin particles is mixed into the resin that forms the surface resin layer, so that thin irregularities appear on the surface of this layer, causing diffuse reflection and further absorbing light. Therefore, the surface becomes matte, which suppresses the high reflection caused by the glossy surface of the aluminum foil as the base material, and has the effect of making printed characters etc. very easy to see.
