It relates to a bag body with a combined fastener.

従来、充填開口部とは別に再封可能な取り出し開口部を設けた、充填不良がなく、ボイル処理、レトルト処理可能なジッパー付き包装袋として、一方の本体フィルム11a には横方向の二本の互いに平行な折り曲げ線により折り曲げられ外方に突出するつまみ部13が形成され、つまみ部の内側の折り曲げ線近傍にはつまみ部を横方向に引き裂き生じる開口予定部15が設けられ、つまみ部を有する本体フィルムの内側には係合突起22を有する狭幅テープ21が熱融着され、狭幅テープの内側に係合凹部32を有する広幅テープ31が本体フィルム11a と熱融着され、狭幅テープと広幅テープは内側に設けられた係合突起と係合凹部からなる咬合具により再封可能に嵌合されたものが開示される（特許文献１参照）。   Conventionally, as a packaging bag with a zipper that is provided with a takeout opening that can be resealed separately from the filling opening and has no filling failure and that can be boiled and retorted, one main body film 11a has two lateral films. A knob portion 13 is formed which is bent by parallel folding lines and protrudes outward, and a pre-opening portion 15 which tears the knob portion in the lateral direction is provided in the vicinity of the bending line inside the knob portion, and has a knob portion. A narrow-width tape 21 having an engagement protrusion 22 is heat-sealed inside the main body film, and a wide-width tape 31 having an engagement recess 32 inside the narrow-width tape is heat-sealed with the main body film 11a. And the wide tape is disclosed so that it can be resealed by an occlusal tool composed of an engagement protrusion and an engagement recess provided inside (see Patent Document 1).

また従来、米などの粒状物を封入した後に開閉自在とするためのジッパー付収納袋の製造方法として、以下のものが開示される（特許文献２参照）。この製造方法は、２枚のプラスチック製の長尺シート体の間に、雄部と雌部により相互に着脱自在な２枚のジッパー半体から成るジッパーを、該ジッパーの雄部と雌部を閉じた状態で、上記２枚の長尺シート体の間に所定間隔部をもって上記シート体の幅方向に差込むジッパー差込工程と、第１ガイド部材・第２ガイド部材の少なくとも一方を受け部材として、熱盤を押圧しつつ上記ジッパー半体を上記シート体に融着するジッパー融着工程と、上記ジッパー融着工程の後に、上記シート体に長手方向の送りを与えることにより、該シート体を下流側の上記第２ガイド部材にガイドさせて上記ジッパーを開くジッパー開離工程と、開いた上記ジッパーを上ロール及び下ロールにて挟圧して閉じると共にジッパー融着部の近傍を融着するボトム融着工程を、有する方法が開示される。この製造方法によれば、長尺シート体を間欠的に送りながら、ジッパーを長尺シート体の幅方向に融着することができる。従って、その後、自動封入装置にて内容物を能率的に封入することができる、とされる。特にこの収納袋の第二の実施形態は、シート体とジッパー半体とが重なる部分に、融着部と、収納袋の内外を通気可能とする非融着部を交互に設けており、非融着部をスロート部としている。   Moreover, conventionally, the following is disclosed as a manufacturing method of the storage bag with a zipper for opening and closing, after enclosing granular materials, such as rice (refer patent document 2).

しかしながら、前者の収納袋はジッパー半体を熱融着によってシート体の裏面に溶着して密着させるものであった。このためジッパーの封着状態において、袋体の内部の空気を脱気することができなかった。また後者の収納袋の第二の実施形態は、シート体とジッパー半体とが重なる部分に、収納袋の内外を通気可能とする非融着部を設けているものの、収納袋内に多くの収納物が収められたときに、係合密着したジッパーの形状によって袋口部分のシート体が引っ張られ、溶着部や係合雄部、雌部の部分でシートが極端に折れ曲がってしまうことで、スロート量が十分に確保されず、脱気機能が十分でないといった問題を有していた。   However, the former storage bag is one in which the zipper half is welded and adhered to the back surface of the sheet body by heat sealing. For this reason, the air inside the bag could not be deaerated in the sealed state of the zipper. The second embodiment of the latter storage bag is provided with a non-fused portion that allows the inside and outside of the storage bag to be ventilated at the portion where the sheet body and the zipper half overlap. When the stored item is stored, the sheet body of the bag mouth part is pulled by the shape of the zipper that is in close contact with the engagement, and the sheet is extremely bent at the welded part, the engaging male part, the female part part, There was a problem that the throat amount was not sufficiently secured and the deaeration function was not sufficient.

そこで本考案は、収納袋内に多くの収納物が収められたときに、係合密着したジッパーの形状によって袋口部分のシート体が引っ張られた場合でもスロート量を十分に確保し、封着状態において十分な脱気機能を有する係合ファスナー、袋体の脱気構造、及びこれを備えた袋体を提供することを課題とする。   Therefore, when a large amount of storage items are stored in the storage bag, the present invention secures a sufficient amount of throat even when the sheet body of the bag mouth portion is pulled due to the zipper shape that is in close contact with the storage bag. It is an object of the present invention to provide an engagement fastener having a sufficient deaeration function in a state, a deaeration structure of a bag body, and a bag body including the same.

上記課題を解決するため、本考案は以下（１）〜（６）の構成を採用している。   In order to solve the above problems, the present invention employs the following configurations (1) to (6).

（１）本考案の係合ファスナーは、所定方向に伸長する第一テープ１１の内面に係合凸部１２が固定された第一ファスナー半体１と、前記第一テープ１１のテープ方向と対称の方向に伸長する第二テープ２１の内面に前記係合凸部１２と係合する係合凹部２２が固定された第二ファスナー半体２とから構成され、前記第一テープ１１と第二テープ２１の内面同士を対向近接させ、係合凸部１２と係合凹部１２とを係合させて封着しうる係合ファスナーであって、
第一テープ、第二テープの少なくともいずれかの外面には、外面上方へ突出してテープの伸長方向に伸びる１本又は複数本の外突条３が形成されることを特徴とする。 (1) The engagement fastener of the present invention is symmetrical with the first fastener half 1 in which the engagement protrusion 12 is fixed to the inner surface of the first tape 11 extending in a predetermined direction, and the tape direction of the first tape 11. A second fastener half 2 having an engagement recess 22 engaged with the engagement projection 12 fixed to the inner surface of the second tape 21 extending in the direction of the first tape 11 and the second tape. 21 is an engagement fastener that can be sealed by bringing the inner surfaces of 21 opposite to each other and engaging the engagement convex portion 12 and the engagement concave portion 12,
One or a plurality of outer protrusions 3 are formed on the outer surface of at least one of the first tape and the second tape so as to protrude upward from the outer surface and extend in the extending direction of the tape.

このようなものであれば、非溶着部を確保しながら外面をシート体に部分溶着固定したときに、部分溶着部間の非溶着部においてシートが急激に折れ曲がってしまったり、係合凹凸部の形成部分の形状に押されてシートが急激に折れ曲がってしまったりすることを防ぐことで、折れ曲がったシート体により通気部が閉塞される事態を防止し得る。   In such a case, when the outer surface is partially welded and fixed to the sheet body while securing the non-welded portion, the sheet may be bent sharply at the non-welded portion between the partially welded portions, By preventing the sheet from being bent sharply by being pushed by the shape of the forming portion, it is possible to prevent the air vent from being blocked by the bent sheet body.

特に、前記外突条は係合凸部又は係合凹部の固定個所よりもずれた位置に形成されることが好ましい。   In particular, it is preferable that the outer ridge is formed at a position shifted from a fixed portion of the engaging convex portion or the engaging concave portion.

（２）前記係合ファスナーにおいて、前記外突条は係合凸部又は係合凹部の固定個所１３よりもずれた位置であって、当該固定個所を跨いだ両幅方向にそれぞれ一本以上形成され、かつ各外突条の突出高さは係合凹凸部の構造高さと異なる高さからなることが好ましい。   (2) In the engagement fastener, one or more outer protrusions are formed at positions shifted from the fixed portions 13 of the engagement convex portions or the engagement concave portions in both width directions across the fixed portions. In addition, it is preferable that the protruding height of each outer protrusion is a height different from the structural height of the engaging uneven portion.

具体的には、係合凹凸部の構造高さよりも低い複数本の外突条が、それぞれ同一形状としてテープ幅方向に断続的に又は連続的に形成される。実施例では等間隔に離間して形成されているが、他にテープ外面にて隣接形成され、テープ断面視にてコルゲート構造の外突条を形成するものとしてもよい。   Specifically, a plurality of outer protrusions that are lower than the structural height of the engaging irregularities are formed intermittently or continuously in the tape width direction as the same shape. In the embodiment, they are formed to be spaced apart at equal intervals. Alternatively, they may be formed adjacent to each other on the outer surface of the tape to form the outer protrusions of the corrugated structure in the sectional view of the tape.

係合凹凸部の構造高さと異なる高さで構成することで、シート体の溶着部に異なる複数段階の高さの変化を強制することとなり、この高さの複数段の変化によって、シート体が極端に折れ曲がって脱気のための通気路をスロート状に確保しやすくしている。   By constructing at a height different from the structural height of the engaging irregularities, the sheet body is forced to change in multiple steps at different heights. It is extremely bent to make it easy to ensure a throat-shaped air passage for degassing.

（３）前記係合ファスナーにおいて、前記第一、第二テープは弾性材からなる薄板で構成され、第一半体１、第二半体２の内面同士を係合封着した状態において、第一テープ、第二テープの両側部が対向面接触して係合凸部又は係合凹部の固定個所１３，２３が外面側に伸長方向へ伸びる膨出部１４，２４を形成するものであり、
この膨出部１４，２４のすくなくともいずれかには、伸長方向に沿って高さを可変させた伸長高さ可変構造４が形成されることが好ましい。 (3) In the engagement fastener, the first and second tapes are constituted by thin plates made of an elastic material, and in a state where the inner surfaces of the first half 1 and the second half 2 are engaged and sealed, The both sides of one tape and the second tape come into contact with the opposing surface, and the fixed portions 13 and 23 of the engaging convex portion or the engaging concave portion form the bulging portions 14 and 24 extending in the extending direction on the outer surface side,
It is preferable that at least one of the bulging portions 14 and 24 is formed with an extension height variable structure 4 whose height is variable along the extension direction.

伸長方向すなわち袋体の幅方向には膨出部１４、２４が亘るところ、この伸長方向に沿って膨出高さを可変させ、高膨出部と低膨出部とを交互に形成することで、その表部に非融着状態で覆設されるシート体との間に、低膨出部における切り欠き領域が形成され、この切り欠き領域が通気路８０となってファスナーの幅方向の通気が確保される（図６参照）。   Where the bulging portions 14 and 24 extend in the extending direction, that is, the width direction of the bag body, the bulging height is varied along the extending direction, and the high bulging portion and the low bulging portion are alternately formed. Thus, a notch region in the low bulge portion is formed between the front surface portion and the sheet body covered in a non-fused state, and this notch region serves as a ventilation path 80 in the width direction of the fastener. Ventilation is ensured (see FIG. 6).

（４）前記係合ファスナーにおいて、対向する第一テープ、第二テープの対向する内面側であって、係合凸部又は係合凹部の固定個所１３よりもずれた位置に、テープ伸長方向に伸びる一本又は複数本の内突条５が形成され、第一、第二テープ間の対向距離を確保することが好ましい。   (4) In the engagement fastener, in the tape extending direction at a position shifted from the engagement inner surface of the first tape and the second tape opposite to each other and from the fixing portion 13 of the engagement protrusion or the engagement recess. It is preferable that one or a plurality of extending inner ridges 5 are formed, and a facing distance between the first and second tapes is secured.

内突条５は第一ファスナー半体、第二ファスナー半体同士の係合の解除を容易にするものであり、また第一テープ、第二テープの両側部が互いに対向する内突条５によってテープ上面方向に押し上げられることで、ファスナーが幅方向に湾曲形成され、これによって通気路８０がより確実に確保される。   The inner ridge 5 facilitates the release of the engagement between the first fastener half and the second fastener halves, and the inner ridge 5 is configured so that both side portions of the first tape and the second tape face each other. By being pushed up in the tape upper surface direction, the fastener is curved and formed in the width direction, whereby the air passage 80 is more reliably secured.

（５）また、本考案の袋体の脱気構造は、前記いずれか記載の係合ファスナーを袋口に溶着したものであって、
互いに両端連結されて袋口を構成する表シート部６、裏シート部７の一方及び他方のシート内面に、前記第一テープ１１、第二テープ２１がそれぞれ、テープ伸長方向に断続的に部分溶着されてなり、
この部分溶着による各溶着部は、テープの幅方向において外突条３及び係合凹凸部の固定個所の膨出部を覆いかつこれらに沿う形状にシート部を変形密着させてなり、
非溶着部８には、各溶着部によるシート部の変形密着によって、袋体の内部空気を脱気させる脱気路８０が形成されることを特徴とする。 (5) Moreover, the deaeration structure of the bag body of the present invention is obtained by welding the engagement fastener according to any one of the above to the bag mouth,
The first tape 11 and the second tape 21 are intermittently partially welded in the tape extending direction to one and the other inner surfaces of the front sheet portion 6 and the back sheet portion 7 that are connected to each other to form a bag mouth. Being
Each welded part by this partial welding covers the bulge part of the fixed portion of the outer protrusion 3 and the engagement uneven part in the width direction of the tape, and the sheet part is deformed and adhered to the shape along these,
The non-welded portion 8 is characterized in that a deaeration path 80 for degassing the internal air of the bag body is formed by deformation adhesion of the sheet portion by each welded portion.

シート体は、外突条３及び係合凹凸部の固定個所の膨出部に沿って変形密着されることで皺部が形成され、この皺部によって非融着部でシート体が自然と上方へ盛り上がり、脱気路８０が確実に確保される。   The sheet body is deformed and adhered along the bulging portion of the fixed portion of the outer protrusion 3 and the engagement uneven portion, so that a collar portion is formed. The deaeration path 80 is reliably secured.

（６）また本考案の袋体は、前記脱気構造を袋口に備え、かつこの袋口の口先方向に隣り合う袋体の底部が連接され、かつ前記袋体の底部方向に隣り合う袋体の袋口が連接された連続袋体を切断することで形成されたものである。   (6) Moreover, the bag body of this invention equips the bag mouth with the said deaeration structure, and the bottom part of the bag body adjacent to the front-end | tip direction of this bag mouth is connected, and the bag adjacent to the bottom part direction of the said bag body It is formed by cutting a continuous bag body in which body bag mouths are connected.

内容物の収容の際には、係合ファスナーを封着状態としたまま、当該袋体の未封の底部側から、係合ファスナー側へ内容物が投入され、内容物の投入によって前記表シート部６、裏シート部７が拡がるように形成された袋体となる。内容物の投入の後、底部の表シート部と裏シート部とを相互溶着して封止状態とする。底部には脱気構造を有していなくてもよいが、内容物がこぼれ出ない程度の小孔を形成して補助的に脱気機能を果たすものとしてもよい。   When the contents are stored, the contents are put into the engaging fastener side from the unsealed bottom side of the bag body while the engaging fastener is kept in a sealed state, and the table sheet is inserted by the contents. It becomes the bag formed so that the part 6 and the back sheet | seat part 7 may expand. After the contents are charged, the front sheet portion and the back sheet portion at the bottom are welded together to form a sealed state. The bottom portion may not have a deaeration structure, but a small hole that does not spill out the contents may be formed to supplementarily perform the deaeration function.

この収納袋は、上記（１）〜（５）いずれか記載の係合ファスナーを連続袋体の側部から挿入・溶着されたものでもよい。なお上記形態とは別に、係合ファスナーをここに溶着した単独の収納袋として形成されたものでもよい。   This storage bag may be one in which the engagement fastener according to any one of the above (1) to (5) is inserted and welded from the side of the continuous bag body. Apart from the above form, it may be formed as a single storage bag with the engagement fastener welded here.

上記構成としたことにより、本考案の係合ファスナー、脱気構造及び袋体は、袋内に多くの収納物が収められたときに、係合密着したジッパーの形状によって袋口部分のシート体が引っ張られた場合でもスロート量を十分に確保し、封着状態において十分な脱気機能を有するものとなる。   Due to the above configuration, the engagement fastener, the deaeration structure and the bag body of the present invention have a sheet body at the bag mouth portion according to the shape of the zipper that is engaged and in close contact when a large amount of stored items are stored in the bag. Even when the is pulled, a sufficient amount of throat is secured, and a sufficient deaeration function is provided in the sealed state.

In the embodiment, they are formed to be spaced apart at equal intervals. Alternatively, they may be formed adjacent to each other on the outer surface of the tape to form the outer protrusions of the corrugated structure in the sectional view of the tape.

係合凹凸部の構造高さと異なる高さで構成することで、シート体の溶着部に異なる複数段階の高さの変化を強制することとなり、この高さの複数段の変化によって、シート体が極端に折れ曲がって脱気のための通気路をスロート状に確保しやすくしている。   By constructing at a height different from the structural height of the engaging irregularities, the sheet body is forced to change in multiple steps at different heights.
