特開２００４−２４４０７１号公報 図５〜７Japanese Patent Laid-Open No. 2004-244071 FIG.

前述のように従来のサンドイッチ用袋は、表フィルムの内側に汚れ防止用フィルムを熱溶着し、裏フィルムの内側にカットテープを貼着するという二度手間がかかり、また、通常、サンドイッチを包装した状態の背面部に相当する裏フィルムの外側、即ち、舌片状摘みの下方に品質表示や消費期限などを印刷したラベルを貼り付けている。従って、袋を開封する際に、舌片状摘みを下方に引っ張ったときに、前記カットテープがラベルに当たり、無理に引っ張るとカットテープが切断し、或いは切断方向がずれる等してスムーズな開封が妨げられるという問題があった。   As mentioned above, conventional sandwich bags require twice the work of heat-sealing the antifouling film on the inside of the front film and sticking the cut tape on the inside of the back film. The label which printed the quality display, the expiration date, etc. is affixed on the outer side of the back film corresponding to the back part of the state of having performed, ie, the downward direction of a tongue-shaped knob. Therefore, when opening the bag, when the tongue-like tab is pulled downward, the cut tape hits the label, and if it is forcibly pulled, the cut tape is cut or the cutting direction is deviated. There was a problem of being disturbed.

本願発明は、表フィルムの内側に汚れ防止用フィルムを熱溶着し、裏フィルムの内側にカットテープを貼り付けるという二度手間がかからないで生産効率のよいサンドイッチ等食品包装用袋を提供することを第一の課題とし、更に、袋を開封する際に、舌片状摘みを下方に引っ張ったときに、前記カットテープがラベルに当たり、カットテープが切断し、或いは切断方向がずれる等してスムーズな開封が妨げられないようにするサンドイッチ等食品包装用袋を提供することを第二の課題とするものである。   The invention of the present application is to provide a food packaging bag such as a sandwich that has a high production efficiency without the need for two steps of heat-seal the antifouling film inside the front film and affix the cut tape inside the back film. As a first problem, when the bag is opened, when the tongue-like tab is pulled downward, the cut tape hits the label, and the cut tape is cut or the cutting direction is deviated smoothly. A second object is to provide a food packaging bag such as a sandwich that prevents unsealing.

本発明は、前記の課題を解決するために、本発明は、重ね合わされた表フィルムと裏フィルムの両側縁部及び先細部の根本部が熱溶着され、反先細部側が食品挿入口となる開口部とされる袋本体と、該袋本体の内部に設けられる汚れ防止用フィルムを具備する食品包装用袋において、前記汚れ防止用フィルムは、幅方向中央部にて幅方向に直角方向に帯状に表フィルムと熱溶着され、該帯状の熱溶着部の両側に２条のミシン目状切り込みが設けられるとともに、先細部側の表フィルムに前記ミシン目状切り込みと平行して開封用切り込みを設けることを特徴とするサンドイッチ等食品包装用袋とする（請求項１）。   In order to solve the above-mentioned problems, the present invention provides an opening in which both side edges of the superposed front film and back film and the base of the taper are heat-welded and the side opposite to the taper is the food insertion opening. In the food packaging bag comprising a bag body that is a part and a dirt prevention film provided inside the bag body, the dirt prevention film is formed in a band shape in a direction perpendicular to the width direction at the center in the width direction. Two perforated cuts are provided on both sides of the belt-like heat-welded portion, and the opening film is provided in parallel with the perforated cuts. It is set as the food packaging bag characterized by these (claim 1).

また、前記の課題を解決するために、本発明は、前記先細部の先端部を熱溶着して、該熱溶着部と前記先細部の根本部の熱溶着部との中間に、前記開封用切り込みの先端部を摘み部として設けることを特徴とする前記のサンドイッチ等食品包装用袋とすることが好ましい（請求項２）。   Further, in order to solve the above-mentioned problem, the present invention is configured to heat-weld the tip of the tapered portion, and to open the intermediate portion between the thermally welded portion and the heat-welded portion of the base portion of the tapered portion. It is preferable to provide a food packaging bag such as a sandwich as described above, characterized in that the tip of the cut is provided as a knob.

また、前記の課題を解決するために、本発明は、少なくとも前記表フィルムが合成樹脂延伸フィルムからなることを特徴とする前記のサンドイッチ等食品包装用袋とすることが好ましい（請求項３）。   In order to solve the above-mentioned problems, the present invention is preferably the food packaging bag for sandwiches and the like, wherein at least the front film is made of a synthetic resin stretched film (Claim 3).

本発明のサンドイッチ等食品包装用袋によれば、前記のように表フィルムと汚れ防止用フィルムを帯状に熱溶着して従来のカットテープが不要となり、カットテープを貼り付ける手間が省略できるので、生産効率を格段に向上する。その上、開封面が表示ラベルの貼着面と反対面である表面側に設けられるので、表示ラベルに邪魔されることなくスムーズに開封することができるという利点がある。また、汚れ防止用フィルムによってサンドイッチ等食品の内容物が表フィルムに付着して汚れることを防止する効果を奏するばかりでなく、従来のカットフィルムが透明性に欠けるのに対して、本発明に係る食品包装用袋の帯状の熱溶着部はフィルムの透明性が損なわれることがなく、袋の内容物をより透視できて見栄えがよく、商品価値を高める効果を奏する。   According to the food packaging bag such as the sandwich of the present invention, as described above, the front film and the antifouling film are heat-bonded in a band shape, so that the conventional cut tape is unnecessary, and the trouble of attaching the cut tape can be omitted. Greatly improve production efficiency. In addition, since the opening surface is provided on the surface side opposite to the display label sticking surface, there is an advantage that it can be smoothly opened without being obstructed by the display label. In addition, the anti-smudge film not only has an effect of preventing the contents of food such as sandwiches from adhering to the surface film and becoming dirty, but also the conventional cut film lacks transparency, and is related to the present invention. The belt-like heat-welded portion of the food packaging bag does not impair the transparency of the film, allows the contents of the bag to be seen more clearly, and has the effect of increasing the commercial value.

本発明を実施するための最良の形態について、以下に詳細に説明する。図１は、本発明の第一の実施の形態にかかるサンドイッチ等食品包装用袋の一例を示した正面図であり、図２は、本発明の第二の実施の形態にかかるサンドイッチ等食品包装用袋の一例を示した正面図である。本図において、同一名称については共通の符号を付することとする。   The best mode for carrying out the present invention will be described in detail below. FIG. 1 is a front view showing an example of a food packaging bag such as a sandwich according to the first embodiment of the present invention, and FIG. 2 is a food packaging such as a sandwich according to the second embodiment of the present invention. It is the front view which showed an example of the bag. In the figure, common symbols are assigned to the same names.

図１において、１は、前記食品包装用袋であって、重ね合わされた表フィルム３と裏フィルム４の両側縁部７，７及び先細部６の根本部９が熱溶着され、反先細部側が食品挿入口となる開口部１２とされる袋本体２と、該袋本体２の内部に設けられる汚れ防止用フィルム５とを具備し、前記汚れ防止用フィルム５は、幅方向中央部にて幅方向に直角方向に帯状に表フィルムと熱溶着され、該帯状の熱溶着部８の両側に２条のミシン目状切り込み１０，１０が設けられるとともに、先細部側６の表フィルム３に前記ミシン目状切り込み１０，１０と平行して開封用切り込み１１，１１が設けられてなる。   In FIG. 1, reference numeral 1 denotes the food packaging bag, in which the side film edges 7 and 7 of the superposed front film 3 and the back film 4 and the base part 9 of the taper 6 are heat-welded, and the anti taper side is It comprises a bag body 2 that is an opening 12 serving as a food insertion port, and a dirt prevention film 5 provided inside the bag body 2, and the dirt prevention film 5 has a width at the center in the width direction. The perforated cuts 10 and 10 are provided on both sides of the belt-like heat-welded portion 8, and the sewing machine is formed on the surface film 3 on the tapered side 6. Opening cuts 11, 11 are provided in parallel with the cuts 10, 10.

この実施の形態における食品包装用袋１の材質は、特に限定されるものではないが、袋内部のサンドイッチ等食品が外部から透視できるように、透明の合成樹脂製のフィルムから構成され、特に表フィルム３は、この食品包装用袋１を開封する際に、摘み部１３を下方に引っ張ったときに、表フィルム３が開封用切り込み１１，１１の延長線に沿って引き裂かれる必要がある。そのために、表フィルム３は、合成樹脂製の延伸フィルム、例えば、二軸延伸ポリプロピレンフィルム（ＯＰＰ）を使用することが好ましい。ＯＰＰは、分子が一軸乃至二軸方向に配向しており、切り込みがあるとそこから容易に引き裂くことができるので本発明の食品包装用袋に適している。   The material of the food packaging bag 1 in this embodiment is not particularly limited, but is composed of a transparent synthetic resin film so that food such as a sandwich inside the bag can be seen through from the outside. When opening the food packaging bag 1, the film 3 needs to be torn along the extended lines of the opening cuts 11 and 11 when the knob 13 is pulled downward. Therefore, the surface film 3 is preferably a stretched film made of synthetic resin, for example, a biaxially stretched polypropylene film (OPP). OPP is suitable for the food packaging bag of the present invention because the molecules are oriented uniaxially or biaxially and can be easily torn from the cut.

前記先細部６において、表フィルム３は、汚れ防止用フィルム５のミシン目状切り込み１０，１０とほぼ平行して開封用切り込み１１，１１が設けられており、摘み部１３は、前記帯状の熱溶着部８によって表フィルム３と汚れ防止用フィルム５が互いに熱溶着されているので、摘み部１３を下方に引っ張れば、表フィルム３と汚れ防止用フィルム５が一体となって根本部９で裏フィルム４から剥離し、更に帯状の熱溶着部８が、恰もカットフィルムのように作用して、汚れ防止用フィルム５の２条のミシン目状切り込みに沿って引き裂かれて、食品包装用袋１を容易に開封することができるのである。   In the tapered portion 6, the surface film 3 is provided with opening cuts 11, 11 substantially parallel to the perforated cuts 10, 10 of the antifouling film 5. Since the front film 3 and the antifouling film 5 are thermally welded to each other by the welded portion 8, if the knob 13 is pulled downward, the front film 3 and the antifouling film 5 are integrated with each other at the root portion 9. The film 4 is peeled off, and the band-like heat-welded portion 8 acts like a cut film and is torn along the two perforated cuts of the antifouling film 5. Can be opened easily.

次に、本発明の第二の実施の形態にかかるサンドイッチ等食品包装用袋について説明する。図２に示すように、この実施の形態における食品包装用袋１は、第一の実施の形態にかかるサンドイッチ等食品包装用袋において、袋本体２の先細部６の先細先端部１６を熱溶着して封止すること、及びこの熱溶着部と前記先細部の根本部９の熱溶着部との中間に、前記開封用切り込み１１の先端部を摘み部１３として設けること、以外は第一の実施の形態にかかるサンドイッチ等食品包装用袋と同様である。   Next, a food packaging bag such as a sandwich according to a second embodiment of the present invention will be described. As shown in FIG. 2, the food packaging bag 1 in this embodiment is the same as the sandwiched food packaging bag according to the first embodiment, in which the tapered tip 16 of the tapered portion 6 of the bag body 2 is thermally welded. Except that the tip of the incision 11 for opening is provided as a knob 13 in the middle between the heat-welded portion and the heat-welded portion of the base portion 9 of the tapered portion. This is the same as the food packaging bag such as the sandwich according to the embodiment.

本発明の第一の実施の形態にかかるサンドイッチ等食品包装用袋を製造するには、先ず、汚れ防止用フィルム用の長尺フィルムに、その幅方向のほぼ中央部に適宜離間する２条のミシン目状切り込み１０，１０を形成し、適宜長さに切断して汚れ防止用フィルム５とする。次に、適宜幅の表フィルム用の長尺フィルムの片面に前記の汚れ防止用フィルム５を重ね合わせて、２条のミシン目状切り込み１０，１０の中間を加熱刃（溶着刃）によって帯状に熱用着すると同時に、汚れ防止用フィルム５の下端部１４を熱溶着して係止する。帯状熱溶着部８の幅は加熱刃（溶着刃）の幅によって決まり、この幅は、通常開封する際の摘み易さや強度を考慮して、３〜１０ｍｍの範囲が好ましい。   In order to manufacture a food packaging bag such as a sandwich according to the first embodiment of the present invention, first, a long film for an antifouling film is formed on two strips that are appropriately separated from each other at a substantially central portion in the width direction. The perforated cuts 10 and 10 are formed, and cut to an appropriate length to obtain the antifouling film 5. Next, the antifouling film 5 is overlapped on one side of a long film for a front film having an appropriate width, and the middle of the two perforated cuts 10 and 10 is formed into a belt shape by a heating blade (welding blade). At the same time as heat wearing, the lower end portion 14 of the antifouling film 5 is heat welded and locked. The width of the band-shaped heat welded portion 8 is determined by the width of the heating blade (welding blade), and this width is preferably in the range of 3 to 10 mm in consideration of the ease of picking and the strength when opening normally.

更に、先細部６の表フィルム及び汚れ防止用フィルムに、２条のミシン目状切り込み１０，１０に沿って切り込み加工を施し、開封用切り込み１１，１１を形成する。ミシン目状切り込みは、複数の切り出しカッターを所定間隔で固定した装置にフィルムを通すか、丸鋸状のカッターを使用する。次に、前記表フィルムの汚れ防止用フィルム５が熱溶着されている面に裏フィルムを重ね合わせ、袋本体２の両側縁部７，７を加熱刃（溶断刃）及び先細部６の根本部９を加熱刃（溶着刃）によって、それぞれ熱溶着して食品包装用袋１を得る。   Further, the surface film of the tip 6 and the antifouling film are cut along the two perforated cuts 10 and 10 to form opening cuts 11 and 11. For perforated cutting, a film is passed through a device in which a plurality of cutting cutters are fixed at a predetermined interval, or a circular saw cutter is used. Next, the back film is overlapped on the surface of the front film on which the antifouling film 5 is thermally welded, and both side edges 7, 7 of the bag body 2 are heated blades (cutting blades) and the base portion of the tapered portion 6. The food packaging bag 1 is obtained by thermally welding 9 with a heating blade (welding blade).

次に、本発明の第二の実施の形態にかかるサンドイッチ等食品包装用袋を製造するには、前記第一の実施の形態にかかるサンドイッチ等食品包装用袋の製造において、先細部６の表フィルム及び汚れ防止用フィルムに、切り込み加工するとともに、前記開封用切り込み１１，１１の先端部に逆Ｕ状の摘み部１３を形成する工程と、先細部６の根本部９を加熱刃（溶着刃）によって、それぞれ熱溶着するとともに、先細先端部１６を熱溶着する工程と、を具備する以外は第一の実施の形態にかかるサンドイッチ等食品包装用袋の製造と同様にして食品包装用袋１を得る。   Next, to manufacture a food packaging bag such as a sandwich according to the second embodiment of the present invention, in the manufacture of a food packaging bag such as a sandwich according to the first embodiment, The film and the antifouling film are cut and processed, and a step of forming an inverted U-shaped knob 13 at the tip of the opening cuts 11, 11, and a base portion 9 of the tip 6 is heated by a heating blade (welding blade) ) In the same manner as in the production of the food packaging bag such as the sandwich according to the first embodiment, except that the step of heat welding and the step of thermally welding the tapered tip 16 are provided. Get.

また、前記熱溶着の加熱方法として、電熱により、又はハイ・フリーカンシー・インダクション・ヒーティング（high-frequency induction heating）により加熱刃自体を加熱する方法以外に、塩化ビニル樹脂等の材料は高周波ウエルダー加熱による方法、オレフィン系樹脂等の材料は超音波加熱による方法によって、プラスチックフィルムをゲル化温度ないし溶融温度に加熱して溶着乃至溶断することによっても同様の目的を達成する。加熱温度は、用いる熱可塑性樹脂の種類に応じてその樹脂のゲル化温度ないし溶融温度、加熱時間を考慮して適宜の温度を選択することが好ましい。加工温度が低過ぎるとフィルムが溶融せず、また、温度が高すぎると溶融したフィルムが粘着性を有し加熱刃に付着し易いからである。また、食品包装用袋１は、一個ずつ加工する以外に、ロール状の表フィルム３に汚れ防止用フィルム５を帯状に熱溶着し、更にこの上にロール状の裏フィルム４を重ねて熱溶断する工程を一連の機械作業によって製造してもよい。   Moreover, as a heating method for the thermal welding, materials such as vinyl chloride resin are used for high frequency in addition to the method of heating the heating blade itself by electric heating or by high-frequency induction heating. The same object can also be achieved by welding by welding or fusing a plastic film to a gelling temperature or melting temperature by a method using welder heating or a method such as olefin resin by a method using ultrasonic heating. It is preferable to select an appropriate heating temperature in consideration of the gelation temperature or melting temperature of the resin and the heating time according to the type of thermoplastic resin used. This is because if the processing temperature is too low, the film does not melt, and if the temperature is too high, the melted film is sticky and easily adheres to the heating blade. In addition to processing the food packaging bags 1 one by one, the antifouling film 5 is thermally welded to the roll-shaped front film 3 in a band shape, and the roll-shaped back film 4 is further stacked on the roll-shaped film 3 for thermal fusing. The process to be performed may be manufactured by a series of mechanical operations.

前記第一の実施の形態及び第二の実施の形態にかかるサンドイッチ等食品包装用袋をそれぞれ２０枚ずつ作成して実験した。フィルムは、表フィルム３、裏フィルム４、及び汚れ防止用フィルム５とも０．０３ｍｍのＯＰＰフィルムを使用した。帯状熱溶着部８の幅は４ｍｍとした。それぞれのサンドイッチ等食品包装用袋について５人のモニタによって、摘み部１３を下方に引っ張って袋の開封のし易さを実験した結果、何れの袋についても、ミシン目状切り込み１０に沿って真っ直ぐに引き裂かれ、頗る開封性に優れていることが確認された。次に、前記袋でサンドイッチを包装し、外観を目視により観察したところ、帯状熱溶着部８も含め全体に透明で、内容物がよく透視でき見栄えがよかった。   Experiments were carried out on 20 food packaging bags, such as sandwiches, according to the first embodiment and the second embodiment. For the front film 3, the back film 4, and the antifouling film 5, 0.03 mm OPP film was used. The width | variety of the strip | belt-shaped heat welding part 8 was 4 mm. As a result of testing the ease of opening the bag by pulling the knob 13 downward with five monitors for each food packaging bag such as a sandwich, each bag is straight along the perforated cut 10. It was confirmed that it was excellent in openability. Next, the sandwich was packaged with the bag, and the appearance was visually observed. As a result, the entire structure including the belt-like heat welded portion 8 was transparent, and the contents could be seen through well, so that it looked good.

図３は、前記実施例により得た第二の実施の形態に係るサンドイッチ等食品包装用袋１にサンドイッチを包装した斜視図であり、開口部を折り畳んで封止するとともに背面部に表示ラベル１５を貼着した状態を示す。図３示すように、摘み部１３が表面に向き、表示ラベル１５が背面部にあるので、袋を開封する際に摘み部１３を下方に引っ張っても表示ラベル１５に邪魔されることはなく、スムーズに開封することができる。また、逆にサンドイッチの斜辺部が裏フィルム４に当接するようにサンドイッチを袋に挿入し、背面部に摘み部１３がくるようにすることも可能である。また、食品包装用袋は、サンドイッチ以外におにぎり等他の食品包装用にも利用できることは言うまでもない。   FIG. 3 is a perspective view in which a sandwich is packaged in a food packaging bag 1 such as a sandwich according to the second embodiment obtained by the above-described embodiment. The state which stuck is shown. As shown in FIG. 3, since the knob 13 is directed to the surface and the display label 15 is on the back surface, even if the knob 13 is pulled downward when opening the bag, the display label 15 is not disturbed. It can be opened smoothly. On the contrary, it is also possible to insert the sandwich into the bag so that the hypotenuse part of the sandwich comes into contact with the back film 4 so that the knob portion 13 comes to the back portion. Needless to say, the food packaging bag can be used not only for sandwiches but also for other food packaging such as rice balls.

本発明に係るサンドイッチ等食品包装用袋は、従来のこの種の食品包装用袋に使用されているカットテープを省略できて、製造の作業効率が向上し、しかも袋の開封が容易で、商品価値を高めることができることから極めて有用なものである。   The food packaging bag for sandwiches and the like according to the present invention can omit the cut tape used in the conventional food packaging bags of this type, improve the working efficiency of the manufacturing, and can be easily opened. It is extremely useful because it can increase its value.
