Abstract

<P>PROBLEM TO BE SOLVED: To solve such a problem that when powder is contained 60% or more as a content, a soft capsule form has not been produced by a conventional manufacturing method. <P>SOLUTION: The soft capsule highly containing powder is the one where the content of the soft capsule is composed of a powder and an oil and fat-based substance, and the weight of the powder is 60-99.9% against the total weight of the content. For example, the soft capsule can be manufactured by utilizing a rotary method equipped with rotary molds 8, supplying the powder in a solid form 3' into a pocket 9 of the one mold 8 by pushing it onto a film sheet 5' from above before the pockets 9 are faced each other, and filling and supplying the oil and fat-based substance 4 between the two film sheets 5', 5' within the faced pockets 9, 9. Because the powder in a solid form 3' is covered with the oil and fat-based substance 4, the content of the soft capsule can be similarly handled as the content for the conventional soft capsule. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は医薬品、食品等に用いられるカプセルに係り、特に油脂系基材に粉末が高含有されたカプセル内容物が皮膜によって内包されたタイプの軟カプセルに関するものである。   The present invention relates to capsules used in pharmaceuticals, foods, and the like, and more particularly to a soft capsule of a type in which a capsule content containing a high amount of powder in an oily base is encapsulated by a film.

カプセルは硬カプセルと軟カプセルとに大別され、従来からいずれのタイプも利用されているが、なかでも軟カプセルは、その名称の示すとおり、柔軟性に富むので割れ難く、しかも内容物を吸湿、酸化などの化学変化から安定的に保護できることから広く利用されている。
しかしながら、軟カプセルを製造する場合には、通常金型が回転式のロータリー法を利用して、二枚の皮膜シートの間に充填された内容物の粘性を利用して該皮膜シートを外方に押し広げることによりポケット形状に沿って立体成形する。
従って、軟カプセルの内容物は、皮膜シートを極力均等に押し広げることができる粘性を有することが求められている。
そのため、内包したい物質が粉末形態の場合には、適当な油脂系基材に懸濁させた懸濁液として使用しており、内容物全量に占める粉末の相対的な重量はかなり抑えられてしまっていた。
Capsules are broadly divided into hard capsules and soft capsules, and any type has been used. However, as the name implies, soft capsules are flexible and difficult to break, and they absorb moisture. It is widely used because it can be stably protected from chemical changes such as oxidation.
However, when manufacturing a soft capsule, the coating sheet is usually removed by using the rotary method in which the mold is rotated and using the viscosity of the contents filled between the two coating sheets. Three-dimensionally molded along the pocket shape by spreading it.
Therefore, the content of the soft capsule is required to have a viscosity that can spread the film sheet as evenly as possible.
Therefore, when the substance to be encapsulated is in powder form, it is used as a suspension suspended in a suitable oil-based base material, and the relative weight of the powder in the total content is considerably suppressed. It was.

上記のような理由から、粉末の量を増やしたい場合には、通常硬カプセルや粉末を加圧して固めた錠剤として提供されている。
しかしながら、硬カプセルの場合には、キャップとボディとの間にできた隙間を介して内容物が吸湿、酸化などの化学変化を受け易く、しかも経口し難い。
また、錠剤の場合には粉末を固形化するのにある程度の量の賦形剤を添加することが不可欠であり、割れや角の崩れも比較的起こり易い。また、内容物の表面が露出してしまうので、吸湿、酸化などの化学変化を諸に受け易いだけでなく、経口の際には内容物に由来する苦味や臭いの不快さが緩和されない。
For the above reasons, when it is desired to increase the amount of the powder, it is usually provided as a hard capsule or a tablet obtained by pressing and solidifying the powder.
However, in the case of hard capsules, the contents are easily subjected to chemical changes such as moisture absorption and oxidation through a gap formed between the cap and the body, and are difficult to take orally.
In the case of tablets, it is indispensable to add a certain amount of excipient to solidify the powder, and cracks and corners are relatively easy to occur. Moreover, since the surface of the contents is exposed, it is not only susceptible to various chemical changes such as moisture absorption and oxidation, but the bitterness and odor unpleasantness derived from the contents is not alleviated when taken orally.

上記した不都合な点を解消するために、様々な硬カプセルや錠剤の表面を被覆したフィルムコート錠や糖衣錠が提案されているが、被覆のために必要な特別な設備や材料、比較的高度な塗工技術、錠剤加工技術が負担となり、製造コストを押し上げてしまう。   In order to eliminate the above disadvantages, film-coated tablets and sugar-coated tablets covering the surface of various hard capsules and tablets have been proposed, but special equipment and materials necessary for coating, relatively advanced Coating technology and tablet processing technology are burdened and increase manufacturing costs.

In the soft capsule of the present invention, the powder content is dramatically increased as compared with the conventional soft capsule.
And the above-mentioned soft capsule can be manufactured using the rotary type soft capsule manufacturing apparatus conventionally used conventionally.

以下、本発明の粉末高含有軟カプセルを、添付図面に示す実施の形態に基づいて詳細に説明する。
(軟カプセルの形状・構造)
特に形状は限定されないが、ロータリー式軟カプセル製造装置を用いて製造する場合には、それに備えられる金型のポケットの形状による。
図1、図2は本発明の実施の形態に係る軟カプセル1の断面図である。この軟カプセル1は、内容物2とそれを覆うカプセル皮膜5とにより構成されている。カプセル皮膜5は後述する二枚の皮膜シートSの接合・打ち抜きにより立体状に成形されており、境界が若干凹んだ接合部分6が形成されている。
乾燥カプセルの皮膜は接合部分6の近傍が最も厚くなり、その中間部分が最も薄くなるが、いずれの部位の厚さ寸法(d1)も、大部分は0.05〜5.00mmの範囲内に収まっている。
Hereinafter, the soft capsules with high powder content of the present invention will be described in detail based on the embodiments shown in the accompanying drawings.
(Soft capsule shape and structure)
The shape is not particularly limited, but when it is manufactured using a rotary soft capsule manufacturing apparatus, it depends on the shape of a mold pocket provided therein.
1 and 2 are cross-sectional views of a soft capsule 1 according to an embodiment of the present invention. The soft capsule 1 includes a content 2 and a capsule film 5 covering the content 2. The capsule coating 5 is formed into a three-dimensional shape by joining and punching two coating sheets S described later, and a joining portion 6 having a slightly recessed boundary is formed.
The film of the dried capsule is thickest in the vicinity of the joint portion 6 and is thinnest in the middle portion, but most of the thickness dimension (d1) of any portion is in the range of 0.05 to 5.00 mm. It is settled.

(内容物の構造)
内容物2は粉末3と油脂系基材4とから構成されている。
図1に示すように、カプセル皮膜5側には油脂系基材4が比較的優先的に存在し、中心側には粉末3が比較的優先的に存在しているか、図2に示すように、カプセル皮膜5に接する側には油脂系基材4の層が形成されている場合がある。
粉末3の素材としては、従来から軟カプセルの内容物として使用されてきたものに限定されず、従来、硬カプセルや錠剤の形態が選択されている素材においても、用いることができる。
(Structure of contents)
The contents 2 are composed of a powder 3 and an oil base 4.
As shown in FIG. 1, the oil base 4 is relatively preferentially present on the capsule film 5 side, and the powder 3 is relatively preferentially present on the center side, as shown in FIG. In some cases, a layer of the oil-based base material 4 is formed on the side in contact with the capsule film 5.
The material of the powder 3 is not limited to those conventionally used as the contents of soft capsules, and can be used in materials that have conventionally been selected in the form of hard capsules or tablets.

また、40℃以下で固体となる脂質を含む油脂系基材4の場合は、充填供給の際には加熱されて適度な流動性を有した液体となっていれば、使用可能である。前述の油を使用した場合には、図1に示すようになる。一方、40℃以下にした場合に固体となる脂質を含む油脂系基材を使用した場合には、軟カプセルの製造後は温度低下によって固化するので、図2に示すように、軟カプセル1のカプセル皮膜5の直下は固形の脂質層、即ち疎水層4’になる。従って、脂肪を使用することにより、カプセル皮膜5の水分がカプセル内部に移行するのを効果的に阻止できるので、粉末が吸水性の高いものの場合に特に有用である。   Moreover, in the case of the fat-type base material 4 containing the lipid which becomes a solid at 40 ° C. or lower, it can be used as long as it is heated at the time of filling and supplying a liquid having an appropriate fluidity. When the above-mentioned oil is used, it is as shown in FIG. On the other hand, in the case of using an oil-based base material containing a lipid that becomes solid when the temperature is 40 ° C. or lower, the soft capsule is solidified by a temperature drop after the production of the soft capsule. Therefore, as shown in FIG. Immediately below the capsule film 5 is a solid lipid layer, that is, a hydrophobic layer 4 ′. Therefore, by using fat, it is possible to effectively prevent the moisture of the capsule film 5 from moving into the capsule, so that it is particularly useful when the powder has high water absorption.

粉末3と油脂系基材4の重量比は、99.9〜60:1〜40の範囲に設定できるが、粉末3の下限値は、従来の軟カプセルとの区別を明確にするために、従来提供されてきた軟カプセルでは到底内包し得てなかった量としている。   The weight ratio of the powder 3 and the fat-based base material 4 can be set in a range of 99.9 to 60: 1 to 40, but the lower limit value of the powder 3 is to clarify the distinction from the conventional soft capsules. The amount of soft capsules that have been provided so far cannot be included.

カプセル皮膜5の素材としては、ゼラチンに可塑剤としてグリセリンやPVAなどを添加して用いられるが、それに限らずに皮膜形成可能な皮膜基材として、プルラン、寒天、カラギーナン、デンプン、デンプン分解物、アルギン酸やHMC(ヒドロキシメチルセルロース)、HPMC(ヒドロキシプロピルメチルセルロース)、ジェランガム、カードラン等や、これらの酸化・アルカリ化した増粘多糖類も使用できる。
さらに、皮膜成分として、天然色素、食用色素、化学合成色素、二酸化チタン、Ca化合物などの着色剤を含むことも可能である。
As a material of the capsule film 5, glycerin, PVA or the like is added to gelatin as a plasticizer, but is not limited thereto. Alginic acid, HMC (hydroxymethylcellulose), HPMC (hydroxypropylmethylcellulose), gellan gum, curdlan, etc., and these oxidized and alkalized thickening polysaccharides can also be used.
Furthermore, it is also possible to include coloring agents such as natural pigments, food pigments, chemically synthesized pigments, titanium dioxide, and Ca compounds as film components.

(Manufacturing method using manufacturing apparatus 7)
As shown in FIG. 3, two coating sheets 5 ′ and 5 ′ are supplied onto rotating molds 8 and 8 from the upper left and right sides.
At the same time, the powder solid 3 'is also sequentially conveyed on the conveyance path 15. And as shown in FIG. 4 (1), it falls on the film sheet 5 'on the right side from the dropping hole 16. FIG. Further, as shown in FIG. 4 (2), when the shaft 18 of the pushing instrument 17 is advanced, the powder solid material 3 ′ is pushed by the abutting piece 19 into the pocket 9 of the mold 8. 'Push from above. Thereafter, the right coating sheet 5 ′ and the left coating sheet 5 ′ are heated appropriately with respect to the segment 10, and the two coating sheets 5 ′ and 5 ′ are moved downward by rotating the molds 8 and 8. Then, the pockets 9 and 9 are brought into contact with each other at the directly facing positions, joined and punched by the action of heat and pressure. At the same time, the oil base 4 is filled and supplied at a predetermined timing by the operation of the supply pump 14 between the two coating sheets 5 ′ and 5 ′, and the coating sheets 5 ′ and 5 ′ are spread outward. As a result, a soft capsule having the shape of the pockets 9 and 9 is obtained. That is, it becomes a soft capsule in which the oil base 4 is present between the coating sheet 5 ′ and the powder solid 3 ′.

また、皮膜シート5’、5’と粉末固形物3’との間には油脂系基材4が存在するので、得られた軟カプセル1は、図1に示すように、接合部分6は若干凹むことは有っても、不恰好な凸状に突出することはない。   Moreover, since the oil-based base material 4 exists between the coating sheets 5 ′ and 5 ′ and the powder solid 3 ′, the obtained soft capsule 1 has a slightly joined portion 6 as shown in FIG. Even if it dents, it does not protrude into an unpleasant convex shape.

以上のカプセルの安定性試験、カプセル過酷試験、カプセル崩解試験の結果より、本発明の軟カプセルは、内容物の油に対しての粉末率が60%以上となる高含有化をしても、収率と崩壊性に関しては特に影響はなかったことが実証された。
さらに、内容物中の油含有量が少ない条件の場合においては、皮膜中の可塑剤を通常より減らして軟カプセル皮膜の強度を低く設定することができる。その理由として、内容物の固型量が多いので、内容物の温度変化があっても内容物が膨張・収縮し難く、皮膜接着部からの液漏れやカプセルの外圧からの衝撃による割れを防ぐことができる。これにより、従来から問題になっている軟カプセルの欠点であるカプセル皮膜の付着性の改善も図れることが実証された。
From the results of the above-described capsule stability test, capsule severe test, and capsule disintegration test, the soft capsule of the present invention has a high powder content of 60% or more with respect to the oil content. It was demonstrated that there was no particular effect on yield and disintegration.
Furthermore, when the oil content in the contents is low, the plasticizer in the film can be reduced from the usual amount, and the strength of the soft capsule film can be set low. The reason for this is that the content is so solid that it is difficult for the content to expand or contract even if the temperature changes, preventing cracking due to liquid leakage from the film adhesive or impact from the external pressure of the capsule. be able to. As a result, it has been proved that the adhesion of the capsule film, which is a drawback of the soft capsule which has been a problem in the past, can be improved.

以上の内容物の酸化比較試験の結果より、本発明の軟カプセルは、カプセル皮膜の内側に油層があることで酸化防止効果を有すること、また、油量が相対的に多くなると、酸化防止効果が長く安定的に持続すること、また、皮膜の内側に固形の脂質層を形成させるとさらなる酸化防止効果が実証された。   From the results of the oxidation comparison test of the above contents, the soft capsule of the present invention has an antioxidant effect due to the presence of the oil layer inside the capsule film, and when the oil amount is relatively large, the antioxidant effect Has been demonstrated to have a long and stable persistence, and when a solid lipid layer is formed inside the film, further antioxidant effect has been demonstrated.

健康食品の場合には、単位体積当たりの有効成分の量をできるだけ多くしながら、同時に有効成分を酸化などから保護できることが求められている。1カプセルに封入できる粉末の量が増えれば、経口摂取するカプセル数を減らすことができ、しかも消費者に安全に提供できるからである。
それに対して、本発明の軟カプセルは、1カプセルに封入できる粉末の量を従来に比べて飛躍的に増量でき、しかも、カプセル皮膜の内側には粉末が油脂系基材の層、通常は油層で囲まれた状態で存在しているため空気酸化し難い。さらに、カプセル皮膜の内側に油脂系基材が含まれているので、粉末が脂溶性のものである場合には錠剤や糖衣錠より、体内吸収性を高めることができる。
従って、本発明の軟カプセルは、特に健康食品の需要拡大に寄与し得るものとなる。
In the case of health foods, it is required that the amount of active ingredients per unit volume be as large as possible while simultaneously protecting the active ingredients from oxidation. This is because if the amount of powder that can be encapsulated in one capsule increases, the number of capsules taken orally can be reduced, and it can be safely provided to consumers.
On the other hand, the soft capsule of the present invention can dramatically increase the amount of powder that can be encapsulated in one capsule as compared with the conventional capsule, and the powder is an oil-based substrate layer, usually an oil layer, inside the capsule film. It is difficult to oxidize air because it is surrounded by. Furthermore, since the oil-based base material is contained inside the capsule film, when the powder is fat-soluble, the absorbability in the body can be improved compared to tablets and sugar-coated tablets.
Therefore, the soft capsule of the present invention can contribute particularly to an increase in demand for health foods.
