Description

本発明は、浸出製品用のフィルターバッグ及びこのようなフィルターバッグの製造方法に関する。 The present invention relates to a filter bag for a leachate product and a method for manufacturing such a filter bag.

具体的には、本発明は、液体浸出製品であって、特に、粉末状、顆粒状、又は茶葉状で（お茶やカモミール等の）温かい液体である製品用のフィルターバッグに関する。 Specifically, the present invention relates to a filter bag for a liquid leachate product, particularly a powdery, granular, or tea leaf-like warm liquid (such as tea or chamomile).

市場には現在異なる二種類のフィルターバッグがあり、いわゆる「従来からの」フィルターバッグであって、実質的には略平坦な最終構造を有するフィルターバッグと、（フィルターバッグを熱成形プロセスによって得る場合には）四面体又は球状等の様々な立体形状を備えたフィルターバッグとがある。 There are currently two different types of filter bags on the market, the so-called "traditional" filter bags, which have a substantially flat final structure and (when the filter bag is obtained by a thermoforming process). There are filter bags with various three-dimensional shapes such as tetrahedrons or spheres.

第一の種類のフィルターバッグは、一以上のフィルター材料部材を上手く折り畳み接合して一以上のチャンバを設け、各チャンバに液体（水）で浸出するよう意図された製品の一回分を含んだものである。 The first type of filter bag is one in which one or more filter material members are successfully folded and joined to form one or more chambers, each chamber containing a single dose of a product intended to be leached with liquid (water). Is.

このように形成したフィルターバッグは、一端をこのフィルターバッグに及び他端をタグに接合した紐と組み合わせてもよく、浸出中にフィルターバッグを取り扱うのにこの紐を使用する。 The filter bag thus formed may be combined with a string having one end joined to the filter bag and the other end to the tag, which is used to handle the filter bag during leaching.

このような種類のフィルターバッグは、現状の機械で比較的簡単に製造され、更に包装が迅速且つ簡単であることから非常に実用的であるという利点を有する。 These types of filter bags have the advantage of being very practical because they are relatively easy to manufacture on current machines and are quick and easy to wrap.

一方、このような種類のフィルターバッグは、その形状（略平坦）故に、顆粒と茶葉等の異なる粗さの浸出製品を収容するのには適していない。茶葉には、異なる格納チャンバが必要であって、即ち、より多くの量の液体を通過可能としてより品質の良い浸出液を得るために、浸出のためのより大きな空間を有するより大きなチャンバが必要である。 On the other hand, these types of filter bags are not suitable for accommodating leached products of different roughness such as granules and tea leaves due to their shape (substantially flat). Tea leaves need different storage chambers, i.e., a larger chamber with more space for leaching in order to allow a larger amount of liquid to pass through and obtain a better quality leachate. be.

立体構造であれば浸出時の取り扱いが容易であって製品が液体と接触可能であるような大きなチャンバを有するので、これらのフィルターバッグがより魅力的となるだけでなく機能的となる。 These filter bags are not only more attractive but also functional because the three-dimensional structure is easy to handle during leaching and has a large chamber that allows the product to come into contact with the liquid.

但し、上述のフィルターバッグはいずれの種類も現在のところ、現在の市場の品目やエンドユーザの仕様が要求するようなニーズの全てを満たすものではない。 However, none of the above filter bags currently meet all of the needs required by current market items and end-user specifications.

具体的には、多くの国際的な市場において、基本製品（例えば、お茶やカモミール）と風味付け製品とを好ましくは浸出時の間のみで組み合わせて使用できるようにすることが必要とされている。 Specifically, in many international markets there is a need to allow basic products (eg, tea and chamomile) and flavored products to be used in combination, preferably only during leaching.

梱包前に製品同士を混ぜて準備したものは除いて、現状のフィルターバッグは、単一のフィルターバッグ内で二つの別々の製品を組み合わせるように設計されておらず及び／又はそのような構造を有さない。 Current filter bags are not designed to combine two separate products within a single filter bag and / or have such a structure, except for those prepared by mixing the products together prior to packaging. I don't have it.

加えて、熱成形プロセスによって得たフィルターバッグは、（プロセスの最後には略不透明になる熱成形を経た材料の構造の本質的な特徴によって）中に含まれる製品がはっきりと見えないので、フィルターバッグの外観上の品質が低下する可能性がある。 In addition, the filter bag obtained by the thermoforming process is a filter because the product contained therein is not clearly visible (due to the essential characteristics of the structure of the thermoformed material which becomes nearly opaque at the end of the process). The appearance quality of the bag may deteriorate.

本発明の目的は、上述の欠点を克服可能な浸出製品用のフィルターバッグを提供することである。 An object of the present invention is to provide a filter bag for a leachate product that can overcome the above-mentioned drawbacks.

本発明の更なる目的は、中に含まれる製品が直接見えるようなフィルターバッグであって非常に魅力的な外観を有するフィルターバッグを提供することである。 A further object of the present invention is to provide a filter bag having a very attractive appearance, which is a filter bag in which the product contained therein can be directly seen.

本発明の更なる目的は、狭い空間内に幾つかの浸出製品を収容可能とすると共に、浸出までは個々の製品の品質的完全性（ｑｕａｌｉｔａｔｉｖｅ ｉｎｔｅｇｒｉｔｙ）を維持することができるフィルターバッグを提供することである。 A further object of the present invention is to provide a filter bag capable of accommodating several leached products in a narrow space and maintaining the quality integrity of individual products until leaching. That is.

更なる目的は、液体浸出製品用のフィルターバッグを製造する方法を提供することである。 A further object is to provide a method of manufacturing a filter bag for a liquid leachate product.

これらの目的は、本発明に係る浸出製品用のフィルターバッグ及びこのフィルターバッグを形成するための方法であって添付の請求項のような特徴を有するフィルターバッグによって完全に達成される。 These objects are fully achieved by a filter bag for a leachate product according to the present invention and a method for forming the filter bag, which has the characteristics as in the accompanying claims.

具体的には、本発明に係る液体浸出製品用のフィルターバッグは、ろ過特性を有し、底部と、上部平坦縁部によって外周を囲われた口部又は開口部と、底部と上縁部との間の接続壁部とによって形成される内部容量を有する熱成形本体部を備える。 Specifically, the filter bag for a liquid leaching product according to the present invention has filtering characteristics, and has a bottom, a mouth or opening surrounded by an upper flat edge, and a bottom and an upper edge. It comprises a thermoformed body having an internal capacitance formed by a connecting wall between the two.

更に本発明によれば、壁部は、互いに分離され熱成形本体部の内部容量内に含まれる、対応する浸出製品を収容するための少なくとも二つのチャンバを形成するように、底部から上縁部へと延びる少なくとも一つのリブを備える。 Further according to the present invention, the walls are separated from each other and contained from the bottom to the top edge to form at least two chambers for accommodating the corresponding leachate contained within the internal volume of the thermoformed body. It has at least one rib extending into.

更に本発明によれば、このフィルターバッグは、非熱成形フィルター材料からなる平坦部材を備える。この平坦部材は、透明性を有し、熱成形本体部の上縁部と結合して開口部を覆いこのようにして得られるチャンバを分離する。 Further according to the present invention, the filter bag comprises a flat member made of a non-thermoformed filter material. This flat member is transparent and combines with the upper edge of the thermoformed body to cover the opening and thus separate the resulting chamber.

好適には、透明性を得るために、この非熱成形フィルター材料は、「織布」又は「不織布」型である。 Preferably, for transparency, this non-thermoformed filter material is of the "woven" or "nonwoven" type.

更に、好適には、透明性を得るために、この非熱成形フィルター材料の通気性の値（ＵＮＩ ＥＮ ＩＳＯ ９２３７）は、１０００ｃｍ3／ｃｍ2・ｓより大きい。 Further, preferably, in order to obtain transparency, the air permeability value (UNI EN ISO 9237) of this non-thermoformed filter material is larger than 1000 cm 3 / cm 2 · s.

好ましくは、この非熱成形フィルター材料の通気性の値は１０００から１００００ｃｍ3／ｃｍ2・ｓであって、３０００から７０００ｃｍ3／ｃｍ2・ｓであることが更に好ましい。 Preferably, a the non-thermoformed filter 10000cm 3 / cm 2 · s breathable values from 1000 material, more preferably 7000cm 3 / cm 2 · s 3,000.

このように構成したフィルターバッグにより、（熱成形本体部の立体容量による）製品浸出と魅力的な外観の両方に関して特に満足のいく結果が得られる。 The filter bag constructed in this way provides particularly satisfactory results in terms of both product leaching and attractive appearance (due to the three-dimensional capacitance of the thermoformed body).

本発明に記載のフィルターバッグの構造によれば、フィルターバッグの液体浸出が起こるまでは互いに分離された二つの異なる浸出製品（例えば、主製品と風味付け製品）を一つの部品内に存在させることが可能となるという利点を有する。 According to the structure of the filter bag described in the present invention, two different leaching products (eg, main product and flavored product) separated from each other are present in one component until liquid leaching of the filter bag occurs. Has the advantage of being possible.

熱成形本体部を閉じるための非熱成形透明部材によって、中に含まれる製品の種類がはっきりと即座に視認可能となる。 The non-thermoformed transparent member for closing the thermoformed body makes the type of product contained therein clearly and instantly visible.

好ましくは、分離リブは、底部の連続性を遮断するように少なくとも一つの更なる内壁を形成するよう上縁部へと延びる。 Preferably, the separating ribs extend to the upper edge to form at least one additional inner wall so as to block the continuity of the bottom.

これに鑑みて、リブは、底部から始まって、その上端部が開口部を閉じるための透明フィルター材料部材と接するように計算された延長部を有する。 In view of this, the rib has an extension calculated starting from the bottom so that the upper end thereof contacts the transparent filter material member for closing the opening.

このような特徴によって、内部チャンバ間の完璧な分離が確実となると共に、フィルターバッグの機械的な形状の密閉性が確実に増加する。 Such features ensure perfect separation between the internal chambers and increase the tightness of the mechanical shape of the filter bag.

本発明の上述の及び更なる特徴は、添付の図面を参照した好適であるがこれに限定するものではない実施形態についての以下の詳細な説明によってより明らかとなるであろう。

添付の図面、特に図１〜１７を参照すると、本発明に係るフィルターバッグは、参照符号１００によってその全体を表すが、液体浸出製品を収容するのに使用される。 With reference to the accompanying drawings, in particular FIGS. 1-17, the filter bag according to the present invention, represented in its entirety by reference numeral 100, is used to house a liquid leachate product.

具体的には、フィルターバッグ１００は、液体浸出製品、特に（粉末状、顆粒状、茶葉状の）お茶やカモミール等の温かい液体に使用される。 Specifically, the filter bag 100 is used for liquid leaching products, especially warm liquids such as tea (powdered, granular, tea leaf) and chamomile.

本発明によれば、液体浸出製品用のフィルターバッグ１００は、ろ過特性を有し、底部２と、（以下に示すように閉鎖された延長部を有する）上部平坦縁部３によって外周を囲われた口部と、底部２と上縁部３との間の少なくとも一つの接続壁部４とによって形成される内部容量を有する熱成形本体部１を備える。 According to the present invention, the filter bag 100 for liquid leaching products has filtering properties and is surrounded by a bottom 2 and a top flat edge 3 (having a closed extension as shown below). The thermoformed main body 1 has an internal capacity formed by a bag and at least one connecting wall 4 between the bottom 2 and the upper edge 3.

更に本発明によれば、壁部４は、互いに分離され熱成形本体部１の内部容量内に含まれる、対応する浸出製品Ｐ１、Ｐ２を収容するための少なくとも二つのチャンバ６、７を形成するように、底部２から上縁部３へと延びる少なくとも一つのリブ５を備える。 Further, according to the present invention, the wall portions 4 form at least two chambers 6 and 7 for accommodating the corresponding leachate products P1 and P2, which are separated from each other and contained in the internal capacity of the thermoformed main body portion 1. As such, it comprises at least one rib 5 extending from the bottom 2 to the top edge 3.

更に本発明によれば、フィルターバッグ１００は、非熱成形フィルター材料からなる平坦部材８を備える。この平坦部材は、透明性を有し、本体部１の上縁部３と結合して開口部を覆いこのようにして得られるチャンバ６、７を分離する。 Further, according to the present invention, the filter bag 100 includes a flat member 8 made of a non-thermoformed filter material. This flat member has transparency and is coupled to the upper edge portion 3 of the main body portion 1 to cover the opening and separate the chambers 6 and 7 thus obtained.

好適には、フィルター材料は、「織布」型である。 Preferably, the filter material is of the "woven" type.

或いは、フィルター材料は「不織布」からなる。 Alternatively, the filter material consists of a "nonwoven fabric".

透明性を有する非熱成形フィルター材料によって、バッグ内に収容した製品を視認可能となる。 The transparent non-thermoformed filter material makes the product contained in the bag visible.

尚、上述の二つの浸出製品Ｐ１及びＰ２がそれぞれいわゆる基本製品（お茶やカモミール）と風味付け製品（例えば、果物及び／又は植物由来の風味）であることが好ましい。 It is preferable that the above-mentioned two leachate products P1 and P2 are so-called basic products (tea and chamomile) and flavored products (for example, flavors derived from fruits and / or plants), respectively.

好ましくは、リブ５は、底部２の連続性を遮断するように少なくとも一つの更なる内壁５ａを形成するよう上縁部３へと延びる（図１〜図１７を参照）。 Preferably, the rib 5 extends to the upper edge 3 to form at least one additional inner wall 5a so as to block the continuity of the bottom 2 (see FIGS. 1 to 17).

言い換えると、リブ５は、底部２から延び、本体部１の元の容量の内部に一以上の壁を生成するよう壁部４の延長部を修正して、底部２と壁部４の両方を分離するものである。 In other words, the rib 5 extends from the bottom 2 and modifies the extension of the wall 4 to create one or more walls inside the original capacitance of the body 1 to provide both the bottom 2 and the wall 4. It is something to separate.

好ましくは、リブ５は、底部２から始まって、その上端部９が開口部を閉じるための透明フィルター材料部材８と接するように計算された延長部を有する。 Preferably, the rib 5 has an extension that is calculated to start at the bottom 2 and have its upper end 9 in contact with the transparent filter material member 8 for closing the opening.

これに鑑みて、リブ５は、本体部１の上縁部３と略同一平面上にある上端部９を有する。 In view of this, the rib 5 has an upper end portion 9 which is substantially flush with the upper edge portion 3 of the main body portion 1.

第一の実施形態のフィルターバッグ１００（図１〜図６）において、上縁部３は円形形状であって、リブ５は、底部２に対の凸状（ｌｏｂｅｄ）形状を形成することによって、同じぐらいの容量の二つのチャンバ６、７を形成するように本体部１を直径に沿って分離するよう構成される。 In the filter bag 100 (FIGS. 1 to 6) of the first embodiment, the upper edge portion 3 has a circular shape, and the rib 5 forms a pair of convex shapes on the bottom portion 2. The main body 1 is configured to be separated along the diameter so as to form two chambers 6 and 7 having the same capacity.

これに鑑みて、リブ５の上端部９は、底部２から始まり上縁部３へと突出する二つの別々の平行内壁を形成する、直線状の延長部を有する。 In view of this, the upper end 9 of the rib 5 has a linear extension that forms two separate parallel inner walls starting from the bottom 2 and projecting to the upper edge 3.

このような形状とするために、リブ５は、距離Ｄだけ互いに離間した二つの壁からなり（図３参照）、この距離がリブ５の上端部９の幅となる。 In order to obtain such a shape, the rib 5 is composed of two walls separated from each other by a distance D (see FIG. 3), and this distance is the width of the upper end portion 9 of the rib 5.

図７〜図１２に示す第二の解決策のフィルターバッグ１００において、上縁部３は円形形状であって、リブ５の上端部９は、底部２から始まり上縁部３へと突出する互いに平行な波状延長部を有する二つの別々の壁を形成する波状の延長部を有する。 In the filter bag 100 of the second solution shown in FIGS. 7 to 12, the upper edge portion 3 has a circular shape, and the upper end portions 9 of the ribs 5 start from the bottom portion 2 and project to the upper edge portion 3 from each other. It has a wavy extension that forms two separate walls with parallel wavy extensions.

尚、リブ５の延長部は「Ｓ字」形状であって、二つのチャンバ６、７が略同一の容量を有するようになっている。 The extension portion of the rib 5 has an "S-shaped" shape, so that the two chambers 6 and 7 have substantially the same capacity.

これに鑑みて、底部２と壁部４とは、底部２に沿って上縁部３の所までＳ字形状の溝を形成する波状の延長部を有する二つの壁によって遮断され、これによって各チャンバ６、７の対応する内壁が形成される。 In view of this, the bottom 2 and the wall 4 are blocked by two walls having a wavy extension that forms an S-shaped groove along the bottom 2 to the top edge 3. Corresponding inner walls of chambers 6 and 7 are formed.

尚、リブ５は、一定の相互距離によって互いに離間した二つの波状の壁を備え、この距離がリブ５の上端部９の幅となる。 The rib 5 is provided with two wavy walls separated from each other by a constant mutual distance, and this distance is the width of the upper end portion 9 of the rib 5.

好ましくは、リブ５の上端部９は、上縁部３と同一平面上にあって、縁部３によって形成された円周上で互いに相対する少なくとも二つの点において縁部３に接続され、更なる上部補助縁部を形成する。 Preferably, the upper end 9 of the rib 5 is coplanar with the upper edge 3 and is connected to the edge 3 at at least two points facing each other on the circumference formed by the edge 3. Form an upper auxiliary edge.

この構造によって、二つのチャンバ６、７間の密閉性と共に熱成形本体部１の機械的密閉性を増すことができる。 With this structure, it is possible to increase the mechanical airtightness of the thermoforming main body 1 as well as the airtightness between the two chambers 6 and 7.

第三の解決策のフィルターバッグ１００（図１３〜図１７）において、上縁部３は円形形状であって、リブ５は、上縁部３の外周の内側に環状の延長部を有するよう構成されて本体部１の内部容量を円形に分離し、容量の異なる二つの別々のチャンバ６、７を形成する。 In the filter bag 100 (FIGS. 13 to 17) of the third solution, the upper edge portion 3 has a circular shape, and the rib 5 has an annular extension portion inside the outer periphery of the upper edge portion 3. The internal capacitance of the main body 1 is separated into a circle to form two separate chambers 6 and 7 having different capacitances.

これに鑑みて、リブ５はリング形状であって、環状の延長部を有する二つのチャンバ６、７を形成するよう上縁部と同心円状である。 In view of this, the rib 5 has a ring shape and is concentric with the upper edge to form two chambers 6 and 7 having an annular extension.

好ましくは、これら二つのチャンバ６、７は、一方が他方の内部にあって、互いに同心円状にある。 Preferably, these two chambers 6, 7 are concentric with each other, one inside the other.

尚、リブ５は、底部２の中心付近に、より少ない容量を有するチャンバ７が、チャンバ７より大きい容量を有するもう一方のチャンバ６で囲まれるように作成されるよう形成される。 The rib 5 is formed so that the chamber 7 having a smaller capacity is surrounded by the other chamber 6 having a capacity larger than that of the chamber 7 near the center of the bottom portion 2.

この場合、リブ５は、上縁部３と同一平面上の上端部９を有するが、上縁部３からは独立しており接点はない。 In this case, the rib 5 has an upper end portion 9 on the same plane as the upper edge portion 3, but is independent of the upper edge portion 3 and has no contact point.
