Abstract

An infusion packet comprises a pair of sealed compartments (12a, 12b) containing infusion material and joined together at opposite ends of the packet. A drawstring (14) attached intermediate its length to a connecting region (8) between the two compartments at one said end has pull portions extending between the compartments from said attachment and held movably at the opposite end of the packet, whereby said pull portions can be drawn apart to contract the packet. To produce the packet the compartments are initially formed end to end, joined by the connecting region. An intermediate portion (16) of the drawstring is attached to the connecting region before the compartments are doubled over to bring their opposite ends together with drawstring pull portions between them. Said opposite ends are then secured together in a manner permitting movement of the drawstring pull portions between them to contract the packet.

Description

【発明の詳細な説明】抽出パケットとその製造法本発明は、例えば茶やコーヒーのような抽出材を包含するパケットであって、抽出の後に水分を絞り出すようにパッケージを収縮させる引き糸(drawstring)または糸(thread)を設けたパケットに関する。このような絞り出し可能なパケットは、小規模に用いられているにすぎない。幾多の提案されたバッグの形態は、非効率的であるか、信頼性に欠けているかであり、例えば使用前に抽出材を漏洩させてしまったり、或いは絞り出しを施す際に、極く容易く裂けてしまう。また他の形態のものにあっては、経済的に生産することができず、また使用に不便があるか、或いはその魅力に欠けている。従って、少なくとも多くの部分について通常の方式で生産でき、しかも引き糸若しくは糸を比較的に単純に、使用において良好な程度の信頼性を与える方式で組み合わせることができるパケットを提供することが望まれる。本発明は、その一つの観点によれば、パケットを製造する方法を与え、そのパケットは、抽出材の一服分を包含して、パケットの対向端部で互いに接続された一対の封止された区画と、この二つの区画の間の引き糸とを備えている。この製造方法では、パケットの一端における接続領域により端と端とを接続して区画を最初に配置し、その接続領域から離間した端部を他方の端部で互いに重ね合わせる状態にする前に、引き糸の長さの中間部分を接続領域へ取り付けて、その引き糸の引っ張り部分を前記中間部分から延伸させ、且つ区画の間からパケットの前記他端への経路をとらせ、また一対の区画を前記他端部で互いに取り付け、その取り付けは、パケットを収縮させるように、前記対向端部を互いへ向かって引くことにより引き糸の前記引っ張り部分の移動を可能とするようにされている。好ましくは、引き糸の各引っ張り部分は、区画が重ね合わせられる前の各区画の長さの中間部で区画の各々に取り外し自在に取り付けられる。引っ張り部分は、パケットの前記他端から突出する端部を都合よく有し、この端部は、区画の前記離間した端部が一体的にされたときに、各々の外部タグ手段に取り付けられて、引き糸の操作を容易にする。本発明の他の観点によれば、抽出パケットが与えられ、このパケットは、抽出材料を包含して前記パケットの対向する端部で互いに接続された一対の封止された区画と、引き糸であって、その長さの中間部分により、前記端部の一方で二つの前記区画の間の接続領域に接続された引き糸とを備え、その引き糸が引っ張り部分を含み、この引っ張り部分は、前記区画の間を前記固定された部分からパケットの前記他端部へ延出して前記他端にて可動に支持されるようにされていることにより、前記パケットを収縮させるように張力をかけることができる。引き糸は、封止手段によって前記端部接続領域の内面へ都合よく取り付けられており、その取り付け位置は、区画を形成する壁と一致しない位置であることが好ましい。引き糸は、区画の実質的に全幅に亘るように、前記一端部において前記領域へ取り付けられることが好ましい。区画の間の引っ張り部分は、前記端部接続領域の横方向オフセット領域からパケットの前記他端における対向横方向オフセット領域へ連続するように配置することが好ましい。パケットの使用に先立って、パケットの前記他端部における引っ張り部分を、パケットの縁および／またはパケットへ取り付けられた引っ張りタグ手段へ取り付け、前記縁および／または引っ張りタグ手段が、パケットを収縮させるように前記他端部からの引っ張り部分の引き抜きを可能とするようにパケットから解離可能とするように配置してもよい。本発明の好適な形態においては、各引っ張り部分は、区画への解除自在な取り付けによりパケットの前記二つの端部の間に保持された余分な長さ、即ちパケットの対向端部の間の最も短い引き糸経路よりも長い長さを有する。区画の間の引き糸がこれら付加的な長さを保持することにより、パケットはその使用がより便利になるように製作できる。余分な長さは、パケットの前記他端部の少なくとも主要な隣接部にまとめることが好ましい。便利さを考慮すれば、余分な長さは、それらの各区画へ曲折パターンで取り付けられ、このパターンは各区画の幅を実質的に横断して延在し得る。更なる好適な特徴においては、区画は、パケットの前記他端において区画の間に開放通路を残すように互いに接続され、その開放通路内では、引き糸引っ張り部分が束縛されて支持されているものの、自由に摺動自在とされている。例示として、本発明について添付図面を参照して更に説明する。図１ａ乃至１ｄは、本発明に係る抽出パケットの形成における一連の工程を示し、図２は、図１に図示された方法により製造されたパケットを示し、図３は、本発明に係る第二の抽出パケットを形成する一対の区画を、パケットの製造の中間工程において、パケットの引き糸と共に示し、図４および図５は、第二のパケットの製造の後続の工程についての各側面図であり、図６は完成したパケットを示し、図７は、図３に示したパターンに対する代替例として糸の他のパターンを示す。図８は、図５におけるパケットの変形例を示す。図９は、図８のパケットを区画の間から余分な糸が既に引き抜かれた後の状態で示し、図１０は、糸の更なる代替パターンであって、図７に類似した方式を示す。図１ａ乃至図１ｄは一連の処理工程を示し、この工程は、熱シール材料の連続的なウェブに対し、このウェブが複数の操作ステーションを連続的に移動通過するにつれてパケット包を形成するように実行できる。図１ａに示される第一のステーションにおいて、一服分の抽出材２は、初めは平坦であるウェブ４上に配置する。次いで、このウェブの側縁を折り重ね、長さ方向シール６で互いに熱シールして、一服分を包含する平坦な筒を形成する（図１ｂ）。次に、個々の一服分を別個の区画１２ａ，１２ｂに封止するように、横帯形シール８，１０を間隔をおいて作成する（図１ｃ）。この段階では連続的ウェブから分離する必要はないが、これらの工程によりもたらされる各パケットの本体は一対の区画１２を含み、この区画は、パケットの一端ではシール帯８により端部と端部とを互いに接続され、且つパケットの他端ではシール帯８よりも幅狭のシール帯１０により閉止されている。ここで引き糸１４のループ状糸を一対の区画の一方の区画１２ａ上に配置する。そのループはウェブ材料上に形成し得るか、或いは予めループを形成した後でウェブ材料上に移動させることができる。このループの中間部分１６をシール帯８（図１ｄ）により形成された接続領域上に配置し、引き糸の一対の端部１８を区画の反対側端部においてシール帯１０を越えて延出させる。突出端部１８はタグ２０に保持させる。糸は、シール帯８とタグ２０へ例えば熱シールにより恒久的に固定する。この糸は、例えば熱溶着（図示せず）により、糸が壁に接する旋回パターンに沿って間隔をおいて区画壁へも取り外し自在に取り付ける。次いで一対の区画１２ａ，１２ｂを面と面とを合わせるようにして二つに折り重ねる。通常はこの段階で一対の区画の分離が完了しており、それら区画の間に引き糸ループが包み込まれる。シール帯８をその長さに沿って折り畳み、区画の間で内方へ突出するＶ字状接続領域を形成させるようにする。区画の自由端部をそれらの封止された縁１０で互いに熱シールするが、糸の端部をそれらの縁の間に通すために、シールされていない通路を残しておく。こうして図２のパケットが形成される。このパケットにおいては二つの区画１２，１２ｂがＶ字状接続領域のシール帯８と端部シール２２とにより、それらの対向端部で互いに取り付けられている。引き糸はパケットの底部における接続領域へ恒久的に取り付けられており、その間には内方へ向かうＶ字状折り畳みが与えられているが、引き糸の大部分は一つの区画の壁に対する所定位置で取り外し自在に保持されている。引き糸の突出端部１８はパケットの上部における端部シール２２内に閉じ込められているが、タグ２０へ取り付けるように突出した箇所から摺動自在である。このパケットを使用する際には、タグ２０を引くことにより、糸ループと区画１２ａの壁との間のタック接合を解離させることができるので、糸ループの余剰な長さを区画の間の空間から解き放ち、引き出すことができる。次いでタグを液体の外部で乾燥状態に保持しながら、パケットを液浸させて抽出させることができる。抽出の後、タグは、その中央切り取り穿孔２４を介して引き裂くことにより二部分へ分離される。次に引き糸端部１８を互いに離すことにより、糸の自由長は引っ張り部分を形成し、これは区画の上部及び下部を引き寄せて、バッグを収縮させて、区画から液体を絞り出す。引き糸ループが、実質的に接続シール帯の二つの端部からパケットの上部における対角線状に対向して広く離間した場所への経路をとる方式は、抽出材の絞り出しの程度を広げる。図３において、パケットを形成する梱包材である平坦な筒状ウェブは、中央接続領域３６を形成する一対の同様な横方向熱シール３４ａ，３４ｂにより二つの別個の区画３２ａ，３２ｂへ分割されて示されており、これらの区画は、その離間した他端において更なる横方向シール３８ａ，３８ｂにより閉じられる。引き糸４０は一対の区画上に配置され、そのパターンは、区画の一側縁４４ａ近傍の端部横方向シール３８ａ上をウェブの縦方向に通過する糸の第一の導入経路４２と、旋回（巻き込み）経路４６とを備え、その旋回経路４６は二つの曲折した折り畳み部を含み、これは端部でシールされ、筒状ウェブの概ね全幅に亘って延伸する。旋回経路４６は導入経路４２に対する対向側縁４４ｂの近傍で終端部し、この糸配置は、接続領域３６に対する対向側縁４４ｂに近接して区画に沿って延伸する直線状経路４８に連続する。次に糸は、接続領域の中央上に筒状ウェブのほぼ横方向全幅を横断して延伸する横方向経路５０を通り、このパターンは、二つの区画のうちの他方の区画では反転した形態で繰り返され、その対応する糸の経路は同様な参照符号に添字ａを付して示されている。糸は熱シールにより都合良くウェブに取り付けられ（但し、全ての例では熱シールに代えて粘着を使用し得る）、接続領域における横方向経路５０の恒久的接着と他の経路の弱くて取り外し自在な接着によれば、糸をそれが配置されている所定パターンに充分に保持させるが、引き糸のこれらの部分は、使用においては一対の引っ張り部分として働くように解放させることができる。旋回経路４６，４６ａの取り付けは、端部シール３８ａ，３８ｂの領域内に完全に制限させられ、区画壁の破断の虞がないことが保証される。好ましくは、連続的筒状ウェブは第一の例で説明したような連続的な抽出材分配およびシール処理により一連の横方向熱シールとして形成され、それにより、一対の区画は端部と端部とを接続された連続的な列として形成され、後の段階で分離される。一対の区画が互いに接続したままで、引き糸をウェブ上の連続的長さに配置できる。引き糸パターンは連続する区画対に連続的に設けられるが、後続の区画対におけるパターンは、先行する区画対におけるパターンの鏡像をなすことに留意されたい。区画の各対は、それに引き糸が前述のパターンで取り付けられた後に、連続的なウェブ長さから分離させる。次いで一対の区画をそれらの接続領域のまわりで互いに折り畳み、それらの互いに離間した端部を互いに合わせる状態にする。これらの端部は、それらの最端部領域、即ち境界５２までの領域上の重ね合わせシールにより互いに固定される。旋回経路４６，４６ａは端部シールから離され、区画の前述の最端部領域を通過する糸の部分は、図示されたシール折り目部分５４の方向へ引き出すことが依然として可能な方式で保持される。折り畳み段階中に、接続領域３６を内方へ畳み込み、横方向シール３４ａ，３４ｂに区画の主本体の間の逆Ｖ字（図２に示す）を形成させる。横方向糸経路５０はＶ字の頂点に置かれる。折り畳まれたタグカード５８は、好ましくはその内面上に熱シールコーティングを有しており、このカードは接続端部上に置いて、端部シールに部分的に重ね合わせ、所定位置に熱シールする。次いで脆弱部分５６の横方向線を端部シール領域に形成し、シールの幅の実質的に中間でタグカード縁に一致させる。所定位置における折り畳まれたタグカードのシールにおいては、引き糸の導入経路がタグカードにより重ね合わせられるウェブ壁の間に、引き糸の導入経路を恒久的に固定する。パケットの製造がこれで完了するが、小さくまとめるためには、パケットをより小型に製作するように、図６に示すようにタグカードを折り畳み得る。敢えて図示しないが、折り畳まれたタグカード５８は、パケットの接続端部の一側部に取り付けられた平坦なカードに置き換え得ることが理解されよう。パケットを使用する際には、タグカード５８をパケットの主本体から脆弱部分５６の線に沿って引き剥がすが、このカードは、脆弱部分５６の線と境界５２との間の端部シールの残りの部分に可動に支持された糸の二つの導入部分４２，４２ａにより主本体に取り付けられたままである。カードは、二つのタグへ分離させることが可能な脆弱部分６０の中心線を有し、各々が導入経路の一方へ取り付けられている。次に二つのタグを引き離すと、旋回経路４６，４６ａの取り外し自在な接着部を裂くことができ、引き糸のその部分を区画の間から引き出すことができる。これで、パケットが浸漬された液体から二つのタグを吊り下げた状態で、パケットに抽出をさせることができる。抽出を終えた際、タグを更に引き離すことができ、ここで直線経路部分４８，４８ａは端部シールを通じて引っ張られて、パケットを収縮させて、余分な水分を絞り出す。使用がより容易なバッグを製作するには、破断に対して、旋回経路４６，４６ａよりも大きな抵抗を有するシールにより直線経路４８，４８ａを取り付ける構成とすることができる。この構成では、使用者が糸の余分な長さを最初に引き出したときに、シールが大きな抵抗を有することを使用者が感じとって、抽出前のパケットの収縮をより容易に回避できる。図７は、例えば図３のパケットに使用可能な引き糸の代替的配置を示す。余分な糸は、図３におけるようなパケットの幅のみではなく、パケットの長さと幅とにわたり中央経路５０から延出したジグザグのパターン７０，７０ａに納められている。図８及び９のパケットは図４乃至６に示されたものと概ね同様であり、対応する部分については同様な参照符号により示してある。いま、二つの区画を互いに接続する端部シールが、導入経路４２，４２ａを通過させる開口チャンネル６２を残すように形成されており、糸の引き出しをより容易にしてある。図９は、余分な糸が区画の間から既に引き出された段階におけるバッグを示し、この段階では、バッグをその内容物を抽出させるように浸漬するための準備ができているが、二つのタグを分離させて、引き糸を引っ張ってパケットを収縮させるのに使用する前の段階である。図１０は、上述したパケット、例えば図３のパケットに使用可能な引き糸１４の更なる代替的配置を示す。上述の例のように、余分な糸は二つの旋回経路８０，８０ａに配置されており、これらの経路は、図３の経路４６，４６ａと同様に、筒状ウェブ（図示せず）の端部シールの領域において、中央経路５０から離間させて配置することができる。各経路８０，８０ａにおいては、糸が、図３の経路４６，４６ａのように三つの通路でウェブの幅を横断するループをなすが、ここでは重ね合わせられている。ここに説明した各例において、ウェブ材料から封止された区画を形成する方法は、公知なものを用いることができるので、既存の装置で実行し得る。その処理には、糸ループの形成と、そのパケットへの取り付けとを比較的に容易に組み込むことができる。本発明の方法によれば、パケットへ固定させる方式でパケットに設けられる引き糸を或る所定長さとすることが可能であり、特に、パケットが引っかかり易い箇所に糸が吊り下がって残ってしまう虞を最小化できる。パケット区画自体の構造に影響することなく、糸ループの形態についての広範な選択をなすことが可能である。引き糸は区画自体の外部に保持されているので、区画に支持される封止されて包含された抽出材料を汚染することはない。図示された例の他の特徴は、糸の取り付けはパケットを脆くする必要が無く、特に、区画を破断し易い張力が糸を通じて加わる区画壁には、糸が恒久的に取り付けられていないので、その個体内容物を抽出させることを可能とする。DETAILED DESCRIPTION OF THE INVENTION Extracted packet and its manufacturing method The present invention relates to a packet containing an extraction material such as tea or coffee, After extraction, the drawstring is used to shrink the package to squeeze out the moisture. Or a packet provided with a thread. Such squeezable packets are only used on a small scale. Numerous proposed bag configurations are inefficient or unreliable Yes, for example when leaking extractor or squeezing before use In addition, it tears very easily. In other forms, economically producing And is inconvenient to use or lacks its appeal. Thus, at least many parts can be produced in the usual manner and Or in a manner that gives the thread a relatively simple, good degree of reliability in use. It is desirable to provide packets that can be combined. The present invention, according to one aspect, provides a method of manufacturing a packet, the method comprising: The packets contained a dose of extractor and were connected to each other at opposite ends of the packet. It has a pair of sealed compartments and a drawstring between the two compartments. This product In the fabrication method, the end-to-end is connected by a connection area at one end of the packet to form a section. Placed first, overlapping ends separated from its connection area at the other end Before pulling, attach the middle part of the draw thread The tension portion of the yarn is extended from the intermediate portion, and between the sections, A route to the other end, and a pair of compartments attached to each other at the other end, Attachment pulls the opposing ends toward each other to shrink the packet Thereby, the movement of the pulling portion of the drawstring is enabled. Preferably, each pulling portion of the drawstring is in each section before the sections are overlapped. Is removably attached to each of the compartments at the middle of the length. The tension portion advantageously has an end protruding from said other end of the packet, The ends are each external tag means when the spaced ends of the compartment are united. To facilitate the operation of the drawstring. According to another aspect of the invention, an extraction packet is provided, wherein the extraction packet is A pair of sealed, containing material and connected to each other at opposite ends of the packet And one of said ends by a middle part of its length A string connected to a connection area between the compartments, wherein the string is pulled Portion, the tension portion being between the compartment and the packet from the fixed portion. Extend to the other end of the unit so as to be movably supported at the other end. Thus, tension can be applied to contract the packet. The drawstring is conveniently attached to the inner surface of said end connection area by sealing means. And the mounting position may not be the same as the wall that forms the compartment. preferable. The drawstring is at the one end forward so as to cover substantially the entire width of the compartment. Preferably, it is attached to the recording area. The tension between the compartments is The opposite lateral direction at the other end of the packet from the lateral offset region of the connection region It is preferable to arrange so as to be continuous to the fset region. Prior to use of the packet, the pulling portion at the other end of the packet is: Takes to the edge of the packet and / or the pull tag means attached to the packet The edge and / or pull tag means to shrink the packet Dissociated from the packet to allow pulling of the pulling part from the other end It may be arranged as possible. In a preferred form of the invention, each pulling portion is releasable into the compartment. The extra length held between the two ends of the packet due to Have a longer length than the shortest draw thread path between the opposite ends of the thread. Pull between parcels As the yarn retains these additional lengths, the packet becomes more convenient to use. It can be made to be profitable. The extra length is at least at the other end of the packet. It is preferable to combine them in the main adjacent part. Considering convenience, the extra length is Attached to each of those compartments in a tortuous pattern, this pattern measures the width of each compartment. It may extend qualitatively across. In a further preferred feature, the partitions are between the partitions at said other end of the packet. Connected to each other to leave an open passage in which Although the parts are bound and supported, they are freely slidable. By way of example, the invention will be further described with reference to the accompanying drawings. 1a to 1d show a series of steps in the formation of an extracted packet according to the invention. And FIG. 2 illustrates a packet produced by the method illustrated in FIG. FIG. 3 shows a pair of partitions forming a second extracted packet according to the present invention, In the intermediate step of the production of FIGS. 4 and 5 are side views of subsequent steps of manufacturing the second packet. Yes, FIG. 6 shows the completed packet, FIG. 7 shows another pattern of yarn as an alternative to the pattern shown in FIG. . FIG. 8 shows a modification of the packet in FIG. FIG. 9 shows the packet of FIG. 8 after the extra thread has already been pulled out from between the sections. , FIG. 10 shows a further alternative pattern of yarn, in a manner similar to FIG. 1a to 1d show a series of processing steps, which consist of a continuous heat sealing material. Web continuously moves through multiple operating stations To form a packet wrapper as The first switch shown in FIG. In the station, a dose of extractant 2 is placed on a web 4 which is initially flat. I do. The side edges of the web are then folded over and heat sealed together with a longitudinal seal 6. To form a flat tube containing a dose (FIG. 1b). Next, an individual dose The horizontal strip seals 8, 10 are spaced apart so that the seals are sealed in separate compartments 12a, 12b. (FIG. 1c). No need to separate from continuous web at this stage However, the body of each packet resulting from these steps includes a pair of compartments 12 In this section, at one end of the packet, the ends are connected to each other by a seal band 8. And the other end of the packet is closed by a seal band 10 narrower than the seal band 8 Have been. Here, the loop-shaped yarn of the drawing thread 14 is arranged on one section 12a of the pair of sections. . The loop can be formed on the web material, or after pre-forming the loop Can be moved over the web material. The intermediate part 16 of this loop is 8 (FIG. 1d), and a pair of ends 18 of the drawstring At the opposite end of the compartment, it extends beyond the sealing strip 10. The protruding end 18 is To be held by the tag 20. The thread is permanently attached to the seal strip 8 and tag 20 by, for example, heat sealing. Fixed. The yarn is wound, for example, by heat welding (not shown) so that the yarn contacts the wall. It is detachably attached to the partition wall at intervals along the pattern. Next, the pair of sections 12a and 12b are folded in two so that the faces are face to face. Overlap. Usually, at this stage, the separation of a pair of compartments is completed, and between these compartments The thread loop is wrapped. Fold the sealing strip 8 along its length, A V-shaped connection region projecting inward between them is formed. The free end of the parcel Heat seal each other with their sealed edges 10, but with the ends of the yarn between them. Leave an unsealed passage for access to Thus, the packet shown in FIG. 2 is formed. In this packet, two partitions 1 2, 12b are formed by the seal band 8 and the end seal 22 in the V-shaped connection area. They are attached to each other at opposite ends. The thread is connected at the bottom of the packet. Permanently attached to the area, with a V-shaped inward fold in between Most of the thread is removed in position against the wall of one compartment It is freely held. The protruding end 18 of the drawstring is an end shell at the top of the packet. That is confined within the tool 22 but protrudes to attach it to the tag 20 And can slide freely. When using this packet, pulling the tag 20 allows the Since the tack joint between the 12a and the wall can be dissociated, excess thread loop A large length can be released and drawn from the space between the compartments. Then remove the tag The packet can be immersed and extracted while keeping it dry outside the body. Wear. After extraction, the tag is then torn through its central cutout 24. Separated into two parts. Next, by separating the drawing thread ends 18 from each other, The length forms a pulling portion, which pulls the top and bottom of the compartment and pulls the bag Shrink and squeeze liquid out of compartment. The draw loop is substantially connected to the sealing band. At the top of the packet, diagonally opposed and widely spaced from the two ends of the The method of taking the path to the squeezer increases the degree of squeezing of the extraction material. In FIG. 3, a flat tubular web, which is a packing material forming a packet, has a center contact. A pair of similar lateral heat seals 34a, 34b forming It is shown divided into separate compartments 32a, 32b, which are separated from each other. At the other end it is closed by further transverse seals 38a, 38b. The draw string 40 is arranged on a pair of sections, and the pattern thereof is one side edge 44a of the section. A first introduction path for the yarn passing in the longitudinal direction of the web over the adjacent end transverse seal 38a A path 42 and a turning (revolving) path 46 are provided, and the turning path 46 has two bends. Fold, which is sealed at the ends and spans approximately the entire width of the tubular web. And stretch. The turning path 46 terminates near the side edge 44b facing the introduction path 42. This thread arrangement follows the section close to the side edge 44b opposite the connection area 36. And a linear path 48 extending along the path. The thread is then placed on the center of the connecting area Through a lateral path 50 extending across substantially the entire lateral width of the web. Is repeated in an inverted manner in the other of the two sections and its corresponding Thread paths are indicated by like reference numerals with the suffix a. The yarn is conveniently attached to the web by a heat seal (however, in all cases the heat seal is (Adhesion may be used in place of the tool), the permanent connection of the lateral path 50 in the connection area. According to the weak and detachable adhesion of the clothes and other pathways, the thread is placed on it These parts of the drawstring, while keeping them well in the predetermined pattern, It can be released to act as a pair of pull parts. Turning path 46, The mounting of 46a is completely restricted to the area of the end seals 38a, 38b. Therefore, it is ensured that there is no risk of breakage of the partition wall. Preferably, the continuous tubular web is a continuous extractable material as described in the first example. Forming and sealing process to form a series of transverse heat seals, The pair of compartments is formed as a continuous row with end-to-end connected, and at a later stage Separated. With the pair of compartments connected to each other, pull the yarn Can be placed The draw string pattern is provided continuously in a continuous pair of sections, The pattern in the following pair of sections is a mirror image of the pattern in the preceding section pair. Note that Each pair of compartments will be successively attached to it after the drawstrings have been attached in the aforementioned pattern. The web length. Then a pair of compartments around their connection area Fold them together and bring their spaced ends together. This These edges are superimposed over their extreme regions, i.e., the region up to boundary 52. Are fixed to each other by the tool. The turning paths 46, 46a are separated from the end seals, The portion of the thread passing through the aforementioned endmost region of the compartment is the seal fold 5 4 is still held in a possible manner. During the folding stage , The connection area 36 is folded inward, and the main seals of the sections are placed on the lateral seals 34a and 34b. An inverted V between the bodies (shown in FIG. 2) is formed. The horizontal yarn path 50 is at the top of the V Is placed. The folded tag card 58 preferably has a heat seal coating on its inner surface. This card is placed on the connection end and partially overlaps the end seal. Align and heat seal in place. Then seal the transverse line of the fragile portion 56 with an end seal. Formed in the area and aligned with the edge of the tag card substantially in the middle of the width of the seal. Fixed position In the seal of the folded tag card in the setting, the introduction path of the thread Permanently introduces the yarn introduction path between the web walls superimposed by Fix it. The packet manufacturing is now complete, but to keep it small, The tag card can be folded as shown in FIG. 6 to make the unit smaller . Although not shown in the figure, the folded tag card 58 is provided at the connection end of the packet. It will be appreciated that a flat card mounted on one side can be substituted. When using a packet, the tag card 58 is moved from the main body of the packet to the vulnerable part. The card is peeled off along the line 56, and the card is separated from the line of the fragile portion 56 by the boundary 52. Between the two introduction portions 42, 4 of the thread movably supported by the rest of the end seal between It remains attached to the main body by 2a. The card is separated into two tags With a centerline of fragile portions 60 that can be attached, each attached to one of the introduction paths Have been killed. Next, when the two tags are separated from each other, the turning paths 46 and 46a are removed. The free adhesive can be split and that part of the drawstring pulled out between the compartments Can be. Now the two tags are suspended from the liquid in which the packet is immersed Thus, the packet can be extracted. When the extraction is completed, the tags can be further separated, where the straight path portion 48, 48a is pulled through the end seal to shrink the packet and remove excess moisture Squeeze out. To make a bag that is easier to use, you need to use The straight paths 48, 48a are provided by seals having a greater resistance than the 46, 46a. A configuration can be adopted. This configuration allows the user to minimize the extra length of thread. When the user first notices that the seal has a high resistance when pulled out In addition, the contraction of the packet before extraction can be more easily avoided. FIG. 7 shows an alternative arrangement of drawstrings that can be used, for example, in the packet of FIG. extra The thread is not only the width of the packet as in FIG. 3, but also the length and width of the packet. Over the zigzag patterns 70, 70a extending from the central path 50 ing. The packets of FIGS. 8 and 9 are generally similar to those shown in FIGS. Are denoted by the same reference numerals. Now, the two compartments The connecting end seal has an open channel 62 for passing through the introduction paths 42, 42a. , So that the yarn can be easily pulled out. FIG. Shows the bag at the stage where the split thread has already been drawn from between the compartments, at this stage Is ready to soak the bag to extract its contents Used to separate two tags and pull the string to shrink packets This is the stage before doing. FIG. 10 shows a string 14 that can be used for the packets described above, for example the packet of FIG. 5 shows a further alternative arrangement of As in the example described above, the extra yarn is , 80a, and these routes are similar to the routes 46, 46a in FIG. Spaced from the central path 50 in the region of the end seal of the tubular web (not shown) Can be arranged. In each of the paths 80 and 80a, the yarn is Three passages form a loop across the width of the web, such as passages 46 and 46a. Here they are superimposed. In each of the examples described herein, a method of forming a sealed compartment from a web material Can be executed by an existing device because a known device can be used. Its processing Incorporates the formation of the thread loop and its attachment to the packet relatively easily Can be taken. According to the method of the present invention, the pull provided in the packet in a manner to fix the packet is used. It is possible for the yarn to be of a certain predetermined length, in particular, packets are easily caught It is possible to minimize the danger that the yarn will be suspended and left in place. The structure of the packet partition itself Extensive choice of thread loop morphology without affecting structure It is. The drawstring is held outside the compartment itself, so the seal supported by the compartment It does not contaminate the contained extraction material. Another feature of the example shown is that the installation of the thread does not require the packet to be brittle, In particular, the yarn is permanently attached to the partition wall where tension that easily breaks the partition is applied through the yarn. Since it is not attached, the contents of the individual can be extracted.
