Description

本発明は、内容物を密封包装する包装袋に関し、包装袋の一端を開封し内容物を取り出す際に開封された表面壁、裏面壁のそれぞれを掴みやすくした包装袋に関するものであり、また、開封後の再開閉において密封性を保持するプラスチック製咬合具を包装袋の対向する内面に取り付け、雌雄の咬合具の咬合により包装袋内面同士を再密着させて開口部の再封鎖を行うことができる包装袋に関する。 The present invention relates to a packaging bag for sealing and packaging the contents, and relates to a packaging bag that is easy to grasp each of the front wall and the back wall that are opened when the contents are taken out by opening one end of the packaging bag, It is possible to re-seal the opening by attaching a plastic occlusion device that retains hermeticity in re-opening and closing after opening to the opposite inner surface of the packaging bag, and re-adhering the inner surfaces of the packaging bag by occlusion of the male and female occlusion devices. It relates to a packaging bag.

従来、内容物を密封包装する包装袋は、包装袋の開口部分から内容物を充填した後、熱接着し密封されており、内容物を取り出す際には、包装袋の一辺に沿って袋を横断するように開封し開口から内容物を取り出されるが、袋体を形成するフィルム素材の特性によっては、胴部を構成する表裏のフィルム内面同士が密着状態となって開口し難い場合や、開封後に胴部表裏のフィルムが内向きにカールし、フィルム端縁が指先で摘み難く、開口し難くなるという欠点もみられた。 Conventionally, a packaging bag for sealing and packaging the contents is sealed by heat bonding after filling the contents from the opening portion of the packaging bag, and when taking out the contents, the bag is placed along one side of the packaging bag. The contents are taken out from the opening and opened so as to cross, but depending on the characteristics of the film material that forms the bag body, the inner surfaces of the film constituting the body part are in close contact with each other and it is difficult to open the opening. Later, the film on the front and back of the body curled inward, and the film edge was difficult to pick up with the fingertips, making it difficult to open.

また、包装袋の開封後にリクローズ性を付与するため、胴部を構成する表裏フィルムの開口部の内側面にプラスチック製咬合具を取り付けた包装袋では、プラスチック製咬合具が咬合した状態で内容物の充填及び包装が行われる。このため、消費者が包装袋を開封するとき、プラスチック製咬合具は強固に咬合した状態となっており開口し難く、さらに咬合具上部の開口部の摘み代が短いために表裏のフィルムが摘み難く、一層、袋を開口し難いという欠点を有していた。 In addition, in order to give recloseability after opening the packaging bag, the packaging bag with the plastic occlusion device attached to the inner surface of the opening part of the front and back films constituting the body part, the contents with the plastic occlusion device engaged. Is filled and packaged. For this reason, when the consumer opens the packaging bag, the plastic occlusion tool is in a state of being firmly occluded and difficult to open. It was difficult to further open the bag.

上記の欠点を解消し、開封箇所の開口性を良好なものとし、開封後の咬合具の分離操作を容易なものとする提案が種々なされている(たとえば、特許文献1)。特許文献1に記載された「合成樹脂製袋体」に開示された技術は、「開口部の内側面に雌雄爪型のチャックを設けた合成樹脂製袋体において前記チャックが形成されている袋体フィルム内側面の両面又は片面のチャック位置の上下部位のそれぞれにチャックと平行する複数のリブ条を突設し、連続した凹凸面を設けたことを特徴とする合成樹脂製袋体」であって、チャック位置の上下部位の袋体フィルム面の面密着を防止すことができ、開口性を良くしたものであり、チャックの変形を防止するものである。 Various proposals have been made to eliminate the above-described drawbacks, to improve the opening of the opening location, and to facilitate the separation operation of the bite after opening (for example, Patent Document 1). The technique disclosed in the “synthetic resin bag body” described in Patent Document 1 is “a bag in which the chuck is formed in a synthetic resin bag body in which a male and female nail type chuck is provided on the inner surface of the opening. A synthetic resin bag body characterized in that a plurality of rib strips parallel to the chuck are provided on both sides of the inner surface of the body film or on the upper and lower portions of the chuck position on one side to provide a continuous uneven surface. Thus, it is possible to prevent the bag film surface of the upper and lower portions of the chuck position from being in close contact with each other, improve the opening property, and prevent deformation of the chuck.

しかしながら、上記特許文献1に記載された合成樹脂製袋体は、開口部のフィルム内側面に突設した複数のリブ条の連続する凹凸面によって、多数条の隙間を形成し表裏フィルムの内側面が密着し難いようにした構造であるため、袋体の開口部内側面の隙間に内容物やゴミが付着するなど衛生面で問題があるとともに、フィルム内側面に設けられたリブ条によって袋体開口部の表面側が平坦な面となり、却って指先で摘みづらく開口し難いという問題があった。また、袋体の開口部が掴みづらいため、開口時に袋を落としたり、強固な咬合状態にある雌雄爪型のチャックの分離操作を無理に行うと、反動で内容物が飛散しやすいという欠点もあった。 However, the synthetic resin bag described in the above-mentioned Patent Document 1 forms a plurality of gaps by the continuous uneven surface of a plurality of ribs protruding from the inner surface of the film of the opening, thereby forming the inner surfaces of the front and back films. Is difficult to adhere to, so there are problems in hygiene such as the contents and dust adhering to the gaps on the inner side of the opening of the bag, and the ribs provided on the inner side of the film open the bag There was a problem that the surface side of the part became a flat surface, and on the contrary, it was difficult to open with a fingertip and it was difficult to open. In addition, it is difficult to grasp the opening of the bag body, so if you drop the bag at the time of opening or forcibly perform the separation operation of the male and female nail type chuck that is in a strong occlusal state, the contents are likely to scatter due to reaction. there were.

図3は、図1におけるY−Y線拡大端面図で、本発明における表面壁および裏面壁の積層構成を表わしている。本発明の開封補助摘みを有するパウチの表面壁1および裏面壁1’は、それぞれ基材層51と中間層52と熱接着性樹脂層53が積層された積層体から形成されている。以下に、基材層51、中間層52、熱接着性樹脂層53のそれぞれについて説明する。
基材層51としては、包装袋を構成する基本素材となることから、機械的、物理的、化学的等において優れた性質を有する合成樹脂製フィルムを用いることができ、例えば、ポリエステル系、ポリアミド系、ポリプロピレン系等の樹脂を用いることができる。また、これらの樹脂を用いたフィルムとしては、未延伸フィルム、あるいは一軸方向ないし二軸方向に延伸した延伸フィルムが使用できる。二軸延伸フィルムを用いる理由としては、通常、基材層51には印刷が施されることが多く、印刷適性が求められるからである。また、基材層51を構成するフィルムの厚さとしては、基本素材としての強度、剛性などについて必要最低限に保持され得る厚さであればよく、コストなどを勘案して決めればよいが、概ね12〜25μm程度である。基材層51としては、延伸フィルムの他、他の合成樹脂フィルムを用いることができ、特に、延伸したフィルムには限らない。さらに、レーヨン紙やグラシン紙などの紙材を用いることができる。
FIG. 3 is an enlarged end view taken along line YY in FIG. 1 and shows a laminated structure of the front wall and the back wall in the present invention. The front wall 1 and the back wall 1 ′ of the pouch having the opening assist knob according to the present invention are each formed of a laminated body in which a base material layer 51, an intermediate layer 52, and a thermal adhesive resin layer 53 are laminated. Below, each of the base material layer 51, the intermediate | middle layer 52, and the thermoadhesive resin layer 53 is demonstrated.
As the base material layer 51, since it becomes a basic material constituting the packaging bag, a synthetic resin film having excellent properties in mechanical, physical, chemical and the like can be used. For example, polyester-based, polyamide Resins such as those based on polypropylene and polypropylene can be used. Moreover, as a film using these resins, an unstretched film or a stretched film stretched in a uniaxial direction or biaxial direction can be used. The reason why the biaxially stretched film is used is that printing is usually performed on the base material layer 51 and printability is required. Further, the thickness of the film constituting the base material layer 51 may be a thickness that can be held to the minimum necessary for strength, rigidity, etc. as a basic material, and may be determined in consideration of the cost, It is approximately 12 to 25 μm. As the base material layer 51, other synthetic resin films can be used in addition to the stretched film, and the stretched film is not particularly limited. Further, a paper material such as rayon paper or glassine paper can be used.

As a constituent material, for example, a metal foil such as aluminum, iron, copper, or tin, or Polyvinylidene chloride is applied to films of polyvinyl alcohol, ethylene-vinyl acetate copolymer saponified products, polyvinylidene chloride, or polyolefins such as polyester, polyamide, polyethylene, polypropylene, ethylene-propylene copolymer, and films of polyvinyl alcohol. A coated film or a film on which an inorganic substance such as aluminum, silicon oxide, aluminum oxide, indium oxide, tin oxide, or zirconium oxide is deposited can be used. Further, the intermediate layer 52 not only provides the above-described light shielding properties and gas barrier properties, but also has mechanical toughness, bending resistance, puncture resistance, impact resistance, cold resistance, heat resistance, chemical resistance, and the like. In order to impart a function, the above-described material imparting light-shielding properties or gas barrier properties can be used in combination with, for example, a film of polyolefin, such as polyester, polyamide, polyethylene, polypropylene, and ethylene-propylene copolymer. .

内層を構成する熱接着性樹脂層53としては、熱により溶融して相互に溶着し得る熱接着性樹脂から形成される層であればよく、包装袋に要求される物性により適宜選択して用いればよく、例えば、低密度ポリエチレン、中密度ポリエチレン、高密度ポリエチレン、直鎖状(線状)低密度ポリエチレン、ポリプロピレン、エチレン−αオレフィン共重合体、エチレン−プロピレン共重合体、エチレン−酢酸ビニル共重合体、アイオノマー樹脂、エチレンとアクリル酸との酸コポリマー、エチレンとアクリル酸エステルとのエステルコポリマー等で形成することができる。 The heat-adhesive resin layer 53 constituting the inner layer may be a layer formed from a heat-adhesive resin that can be melted by heat and welded to each other, and can be appropriately selected and used depending on the physical properties required for the packaging bag. For example, low density polyethylene, medium density polyethylene, high density polyethylene, linear (linear) low density polyethylene, polypropylene, ethylene-α olefin copolymer, ethylene-propylene copolymer, ethylene-vinyl acetate copolymer It can be formed of a polymer, an ionomer resin, an acid copolymer of ethylene and acrylic acid, an ester copolymer of ethylene and acrylic acid ester, or the like.

図4(a)(b)(c)は、本発明に係る開封補助摘みを有するパウチの実施形態の使用状態を示す説明用斜視図で、図4(a)は、図1及び図2で示した袋体Pに内容物を充填収納し、上端の開放端を熱接着して封入した状態で、予め一方側若しくは両側の側端熱接着部11の上端近傍に設けられたノッチ14の開封開始部から、横断して切り破り開封する前の状態を示している。袋体Pの開封位置は、袋体表面に印刷等で開封線を示しておくことが望ましいが、さらに、開封位置に易開封加工を施すこともできる。易開封加工としては、例えば図に示したノッチ14のようなI字形やV字形、U字形の切り込み、切欠部の加工や、微細な切目の穿設による開封開始部の形成と、これに続いて袋体Pを横断する半切線からなる開封予定線15の加工や、同じく袋体Pを横断する方向に一致する延伸方向の一軸延伸フィルムを積層フィルム中に使用するなどの方法が用いられる。尚、上記した半切線からなる開封予定線15の加工は、レーザー光照射によっても加工ができるが、開封予定線の加工は、連続する直線状に限ることなく、断続する破断線で設けることもできるし、又、複数の並行する切目や表裏で切目の位置を変えることにより、より開口を容易なものとする加工も可能である。 4 (a), 4 (b), and 4 (c) are explanatory perspective views showing the usage state of the embodiment of the pouch having the opening assist knob according to the present invention, and FIG. 4 (a) is shown in FIGS. Opening of the notch 14 provided in the vicinity of the upper end of the side end thermal bonding portion 11 on one side or both sides in a state where the bag body P is filled with the contents and the open end of the upper end is thermally bonded and sealed. It shows the state before cutting and opening across from the start. As for the opening position of the bag body P, it is desirable to show an opening line on the surface of the bag body by printing or the like, but an easy opening process can also be applied to the opening position. The easy opening process includes, for example, I-shaped, V-shaped and U-shaped incisions such as the notch 14 shown in the figure, U-shaped cutting, formation of an opening start portion by drilling fine cuts, and subsequent steps. For example, a method of processing the scheduled opening line 15 formed of a half-cut line that crosses the bag body P, or using a uniaxially stretched film in the stretching direction that coincides with the direction crossing the bag body P in the laminated film is used. In addition, although the process of the unscheduled opening line 15 which consists of a half cut line mentioned above can be processed also by laser beam irradiation, the process of the unscheduled opening line is not restricted to a continuous straight line, but may be provided by an intermittent break line. Moreover, the process which makes an opening easier is also possible by changing the position of a notch in several parallel notches and front and back.

図4(b)は、本発明の開封補助摘みの操作による袋体の開口状態を示す斜視図であって、袋体Pの側端熱接着部11の上端に設けられた開封開始端のノッチ14から袋体Pを横断して切り破り、表面壁1および裏面壁1’それぞれの上端に設けられたヒレ状突出片20及び20’の中央部に刻設された略平行な二条の切目線からなる可動用切断線24、24及び24’、24’で区設された摘み部23及び23’をそれぞれ把持して、表裏方向(図中矢印で示す)へ引っ張ることにより、開口端の下部内側面にそれぞれ取り付けたプラスチック製咬合具Q、Q’の雌雄の咬合を解くと共に、開封により形成された上端縁を開口縁として、容易に開口することができるものである。表裏面のヒレ状突出片20、20’はそれぞれ表面壁1および裏面壁1’から外側に延設されているので、使用者が認識し易く、また開口操作にあたって把持し易いものである。上記のように、プラスチック製咬合具付きの袋体において、ヒレ状突出片の摘み部の把持により強固な咬合による密封状態を容易に分離することが可能であり、袋体を取り落としたり、開口操作による内容物の飛散や散逸が発生し難く、内容物の損失や付近の汚損等を抑制することができる。 FIG. 4B is a perspective view showing the opening state of the bag body by the operation of the opening assist knob of the present invention, and is a notch at the opening start end provided at the upper end of the side end thermal bonding portion 11 of the bag body P. 14 cut across the bag body P, and two parallel cut lines engraved at the center of fin-like projecting pieces 20 and 20 'provided at the upper ends of the front wall 1 and the back wall 1', respectively. Gripping portions 23 and 23 'defined by movable cutting lines 24, 24 and 24', 24 ', respectively, and pulling in the front and back direction (indicated by arrows in the figure), thereby lowering the opening end While opening and closing the male and female plastic articulating tools Q and Q ′ attached to the inner side surfaces, the upper edge formed by opening can be easily opened. Since the fin-like protruding pieces 20 and 20 ′ on the front and back surfaces are extended outward from the front wall 1 and the back wall 1 ′, respectively, the user can easily recognize them and can easily grasp the opening operation. As described above, in a bag body with a plastic occlusion tool, it is possible to easily separate the sealed state by a strong occlusion by gripping the knob of the fin-like protruding piece, and the bag body can be removed or opened It is difficult for the contents to scatter and dissipate due to the above, and it is possible to suppress the loss of the contents and the fouling in the vicinity.

図4(c)は、本発明に係る開封補助摘みを有するパウチの、開封後の再閉鎖状態を示す説明用斜視図であって、使用後は、表面壁1および裏面壁1’を所定位置に戻すと共に、プラスチック製咬合具Q、Q’をそれぞれ雌雄咬合させることにより、袋体は再閉鎖される。図4(c)において、ヒレ状突出片20、20’の中央部の摘み部23、23’は、先述した開口操作によって僅かに浮き上がった状態となって、次の開口操作の際に摘み易い状態となる。 FIG. 4 (c) is an explanatory perspective view showing a reclosed state after opening of the pouch having the opening assisting knob according to the present invention, and after use, the front wall 1 and the rear wall 1 ′ are placed at predetermined positions. The bag body is reclosed by bringing the plastic articulating tools Q and Q ′ into mesh with each other. In FIG. 4C, the knobs 23 and 23 ′ at the center of the fin-like protruding pieces 20 and 20 ′ are slightly lifted by the opening operation described above, and are easily picked at the time of the next opening operation. It becomes a state.

図5は、本発明に係る他の実施形態を示す説明用平面図で、開封補助摘み部分の別形状展開例を示しており、袋体P’を形成する表面壁101および裏面壁101’からそれぞれ延設形成されるヒレ状突出片120、120’は、表面壁101および裏面壁101’のそれぞれ上端近傍の折り返し位置R’で折り返され、先述の実施形態の長さより大きな所定長さの折り返し寸法r’の表面側折返部121、121’と裏面側折返部122、122’とがそれぞれ内面で熱接着された後に、それぞれ中央部に突出する摘み部123、123’を形成し該摘み部123、123’のそれぞれ両側は前記摘み部123、123’より幅狭の熱接着部とすると共に前記突出する摘み部123、123’の両側端から前記ヒレ状突出片の幅方向に直交する平行な二条の切目線からなる可動用切断線124、124、124’、124’をそれぞれ穿設形成するよう平面視で変形凹形の切断刃と可動用切断線を形成する切断刃を有する抜き型等でトリミングして形成されており、このように構成することにより、摘み部123、123’が大きく摘み易いので、開封補助摘みの引っ張り操作をより容易なものとすることができる。また、前述した実施形態と同様に、プラスチック製咬合具の取り付け位置は、開口操作により雌雄咬合部の分離が行われるように、摘み部が形成される位置より下部すなわち下端熱接着部側で表面壁、裏面壁それぞれの内側面としたが、これに限定されるものではなく、摘み部のそれぞれ外向きに引っ張る力がプラスチック製咬合具の雌雄咬合部にそれぞれ伝わり易い位置に設けることが好ましく、摘み部を把持して表裏面外向き方向に加えた力が、直截的にプラスチック製咬合具の分離に働き、より小さな力で袋体の変形等を生じることなく開口できるので、開口操作による内容物の飛散や散逸は発生し難く、内容物の損失や付近の汚損等を抑制することができる。 FIG. 5 is an explanatory plan view showing another embodiment according to the present invention, showing an example of another shape development of the opening assist knob portion, from the front wall 101 and the back wall 101 ′ forming the bag body P ′. The fin-like projecting pieces 120 and 120 'formed to extend are folded back at a folding position R' in the vicinity of the upper ends of the front wall 101 and the back wall 101 ', respectively, and are folded back by a predetermined length larger than the length of the previous embodiment. After the surface-side folded portions 121 and 121 ′ and the back-side folded portions 122 and 122 ′ having the dimension r ′ are thermally bonded on the inner surfaces, respectively, knob portions 123 and 123 ′ that protrude from the center portion are formed to form the knob portions. Each of both sides of 123 and 123 ′ is a heat-bonding portion having a width narrower than that of the knobs 123 and 123 ′, and perpendicular to the width direction of the fin-like protruding pieces from both side ends of the protruding knobs 123 and 123 ′. The movable cutting lines 124, 124, 124 ′ and 124 ′ each formed of two parallel cut lines are formed by drilling and forming a deformed concave cutting blade and a cutting blade for forming the movable cutting line in plan view. By trimming with a punching die or the like, the knobs 123 and 123 ′ are large and easy to pick, so that the pulling operation of the opening assist knob can be made easier. Similarly to the embodiment described above, the plastic occlusal attachment position is lower than the position where the knob portion is formed, that is, on the surface at the lower end thermal bonding portion side so that the male and female occlusion portions are separated by opening operation. The inner surface of each of the wall and the back wall, but is not limited to this, it is preferable to provide at a position where the pulling force of each of the knobs is easily transmitted to the male and female occlusion parts of the plastic occlusion tool, The force applied in the outward direction of the front and back surfaces by gripping the knob part directly works to separate the plastic occlusion tool, and can be opened with less force without causing deformation of the bag body. Scattering and dissipation of objects are unlikely to occur, and loss of contents and fouling in the vicinity can be suppressed.

上記の構成によれば、中央部の摘み部123、123’が大きいので、例えば、摘み部123、123’の把持予定部分にそれぞれに平行な複数の切目線群を刻設することも可能となり、刻設した切目線群が摘み部分の摩擦抵抗を増加させるので、開封補助摘みの引っ張り操作を容易なものとすることができる。また、同様の効果は、摘み部123、123’のそれぞれ摘み部分に穿孔部を設けることにより、把持する際の摩擦抵抗を増加させたり、指掛穴としても使用できるので安定した把持が可能となり、より容易な開口操作を得ることができる。 According to said structure, since the knob | pick parts 123 and 123 'of a center part are large, it also becomes possible to engrave a plurality of cut line groups parallel to each part to be held of knob parts 123 and 123', for example. Since the engraved cut line group increases the frictional resistance of the knob portion, the pulling operation of the opening assist knob can be facilitated. In addition, the same effect can be obtained by providing a perforated portion in each of the knob portions 123 and 123 ′, thereby increasing the frictional resistance when gripping and using it as a finger hooking hole, thus enabling stable gripping. An easier opening operation can be obtained.

本発明の開封補助摘みを有するパウチの製造は、実施形態のように、表面壁及び裏面壁を少なくとも基材層と熱接着性樹脂層の内層とからなる矩形状の積層フィルムで構成し、前記表面壁及び裏面壁の両側端部及び下端部を熱接着して両側端熱接着部と下端熱接着部を形成した袋体において、前記表面壁および裏面壁の上端近傍にそれぞれ折り返し位置を設けて外向きに折り出す表面側折返部と該表面側折返部の端部で屈曲され同幅で内向きに折り返される裏面側折返部とを形成し、前記表面側折返部と裏面側折返部とをそれぞれ内層同士で熱接着してヒレ状突出片を形成することができる。尚、例えば、下端部で連続する表面壁および裏面壁を、前記下端部で折り曲げて表裏面を重合し内層同士を熱接着して下端熱接着部を形成し、表面壁および裏面壁それぞれの折り返し位置で折り出される表面側折返部と裏面側折返部とをそれぞれの内層同士で熱接着してそれぞれヒレ状突出片とを形成した後、重合した表面壁および裏面壁を両側端部で熱接着して両側端熱接着部を形成して、上端を開放した四方シール袋とすることもできる。 The production of the pouch having the opening assist knob according to the present invention, as in the embodiment, comprises a rectangular laminated film consisting of at least a base layer and an inner layer of a heat-adhesive resin layer on the front wall and the back wall, In a bag body in which both side end portions and bottom end portions of the front wall and the back wall are thermally bonded to form both side end heat bond portions and bottom end heat bond portions, folding positions are provided in the vicinity of the top ends of the front wall and the back wall, respectively. Forming a front-side folded portion that folds outward and a back-side folded portion that is bent at the end of the front-side folded portion and folded inward with the same width; and the front-side folded portion and the back-side folded portion Each of the inner layers can be heat-bonded to form a fin-like protruding piece. In addition, for example, the front wall and the back wall that are continuous at the lower end are folded at the lower end to superimpose the front and back surfaces, and the inner layers are thermally bonded to form the lower end heat-bonded portion. The front side folded part and the back side folded part that are folded at the position are thermally bonded to each other to form fin-like protruding pieces, and then the superposed surface wall and the back wall are thermally bonded at both ends. Thus, a four-side sealed bag having an open upper end can be formed by forming both end thermal bonding portions.
