Description

この発明は、複数の包装袋が切離し可能に連続している連続型包装袋に関する。 This invention relates to a continuous packaging bag in which multiple packaging bags are connected in a detachable manner.

連続型包装袋は、切離しのためのミシン目を介して連続しロール状に巻かれている。包装袋の使用に際しては、包装袋を分離したのち口を開く必要があるが、口はミシン目でつながっていた部分であるので、切離し後であっても開きにくい。例えばサッカー台に備えられたいわゆるロールポリ袋のように、包装袋を構成する合成樹脂フィルムが薄ければ薄いほど開口は困難である。 Continuous packaging bags are wound up in a continuous roll with perforations for separation. When using the packaging bag, it is necessary to separate the packaging bag and then open the opening, but since the opening is the part that was connected by the perforation, it is difficult to open even after separation. For example, the thinner the synthetic resin film that makes up the packaging bag, such as the so-called rolled plastic bags provided on soccer tables, the more difficult it is to open it.

下記特許文献１の包装袋は、開口部に熱をかけてしわ付けしたものである。しわが付いているので開封がしやすくなる。 The packaging bag in Patent Document 1 below has the opening creased by applying heat. The creases make it easier to open.

下記特許文献２の包装袋は、開口部に凹凸形状のエンボス部を形成したものである。エンボス部は冷間で圧縮加工して得られる。 The packaging bag in Patent Document 2 below has an embossed portion with a concave-convex shape formed at the opening. The embossed portion is obtained by cold compression processing.

これらの構成では、開封しやすくなるものの、製造に際してしわ付けやエンボス部形成のための時間が必要であり、連続型包装袋の製造が効率よく行えない。 Although these configurations make it easier to open, they require time during manufacturing to create wrinkles and emboss the bag, making it difficult to efficiently manufacture continuous packaging bags.

下記特許文献３の包装袋は、ミシン目の長手方向の中間部に底シールに向けて三角形に突出する突出部を形成したものである。この包装袋では切り離すと開口する部位に突出部が存在するので、開口しやすいとされている。 The packaging bag in Patent Document 3 below has a triangular protrusion formed in the middle of the longitudinal direction of the perforation toward the bottom seal. This packaging bag is said to be easy to open because the protrusion is located at the part that opens when the bag is cut.

しかし、突出部を形成するぶん、ミシン目と底シールの間に適宜の距離を置かなければならないので、歩留りが悪い。 However, to form the protrusion, an appropriate distance must be left between the perforation and the bottom seal, resulting in poor yield.

下記特許文献４の包装袋は、開口部の近傍に丸い開封補助用貫通孔を貫通形成したものである。開封に際しては開封補助用貫通孔を指で挟んで動かす。 The packaging bag in Patent Document 4 below has a round through hole formed near the opening to assist in opening. When opening the bag, the through hole is pinched and moved between fingers.

しかし、このように貫通した孔を形成するということは、製造に際してゴミが出ることである。 However, forming holes through the material in this way creates waste during manufacturing.

特公昭５３－２３７４８号公報Japanese Patent Publication No. 53-23748 特開２００８－１３２０３号公報JP 2008-13203 A 特許第３７４３８９０号公報Patent No. 3743890 特開２０００－２５５５９０号公報JP 2000-255590 A

そこでこの発明は、開口しやすくするための構成が製造時における搬送過程で円滑に形成できるとともに、製造工程でのごみの発生をなくすことを主な目的とする。 Therefore, the main objective of this invention is to enable the structure for easy opening to be smoothly formed during the transport process during manufacturing, while eliminating the generation of waste during the manufacturing process.

そのための手段は、複数の包装袋が切離しのためのミシン目を介して連続しロール状に巻かれた連続型包装袋であって、前記包装袋の片面の前記ミシン目における長手方向の一部に、破断された前記ミシン目を端に備える開封端緒が形成された連続型包装袋である。 The means for this is a continuous type packaging bag in which multiple packaging bags are wound into a roll in a continuous manner with perforations for separation, and an opening edge with the broken perforations at one end is formed in a portion of the longitudinal direction of the perforations on one side of the packaging bag.

この構成では、開封端緒は、目の間隔が広いミシン目のようになっており、包装袋の他方の面に対する密着が解かれた状態である。包装袋をミシン目で切り離すときに開封端緒を指先で保持して引っ張れば、切離しと同時に開口が行える。 In this configuration, the opening end is perforated with wide spacing, and is in a state where it is no longer in contact with the other side of the packaging bag. When cutting the packaging bag along the perforation, if you hold the opening end with your fingertips and pull it, you can cut it off and open it at the same time.

この発明によれば、開封端緒を有しているので開口が容易であり、商品等の収納作業が簡易に素早く行える。開封端緒はミシン目を破断して得られるので製造時における搬送過程で容易に形成できる。しかも、開封端緒の形成はミシン目を破断するだけでよいので、製造工程においてゴミの発生を防止できる。 According to this invention, the opening end is easy to open, and storing products can be done quickly and easily. The opening end is obtained by breaking the perforation, so it can be easily formed during the transportation process during manufacturing. Moreover, since the opening end can be formed simply by breaking the perforation, waste can be prevented from being generated during the manufacturing process.

この発明を実施するための一形態を、以下図面を用いて説明する。 One embodiment of the invention is described below with reference to the drawings.

図１に、少し引き出した状態の連続型包装袋１１の一部破断斜視図を示す。連続型包装袋１１は、複数の包装袋１２が切離しのためのミシン目１３を介して連続しロール状に巻かれたものであり、引き出し可能に保持されたり箱に収容されたりして使用される。 Figure 1 shows a partially cutaway perspective view of a continuous packaging bag 11 in a slightly pulled-out state. The continuous packaging bag 11 is made up of multiple packaging bags 12 wound into a roll with perforations 13 for separation, and is used by being held in a pull-out state or stored in a box.

連続型包装袋１１の素材はポリエチレン等の合成樹脂であり、連続型包装袋１１は薄いフィルム状に形成されている。包装袋１２は、いわゆるボトムシール型であり、底のみがシールされた形態の袋である。つまり、包装袋１２は偏平なチューブに包装袋１２の開口となるミシン目１３と、包装袋１２の底となる底シール１４が平行に形成されている。ミシン目１３と底シール１４はチューブの幅全体に直線状に形成される。ミシン目１３は包装袋１２の厚み方向に貫通している。 The material of the continuous packaging bag 11 is a synthetic resin such as polyethylene, and the continuous packaging bag 11 is formed in the form of a thin film. The packaging bag 12 is a so-called bottom-seal type, and is a bag in which only the bottom is sealed. In other words, the packaging bag 12 is a flat tube with perforations 13 that form the opening of the packaging bag 12 and a bottom seal 14 that forms the bottom of the packaging bag 12 formed in parallel. The perforations 13 and the bottom seal 14 are formed in a straight line across the entire width of the tube. The perforations 13 penetrate the packaging bag 12 in the thickness direction.

包装袋１２はすべて同一姿勢で連続しているとともに、包装袋１２の底が引き出し方向Ｄ１に向けられている。つまり、ひとつの包装袋１２について、包装袋１２の開口となるミシン目１３が巻取り方向Ｄ２前方に、包装袋１２の底となる底シール１４が巻取り方向Ｄ２後方に配設される。隣り合う包装袋１２の底シール１４とミシン目１３の間は、包装袋１２のいわゆるスカート１５となる部分であり、その長さは適宜設定されるが、短いほうが歩留りを良くできる。 All the packaging bags 12 are continuous and in the same position, with the bottoms of the packaging bags 12 facing the unwinding direction D1. That is, for each packaging bag 12, the perforation 13 that forms the opening of the packaging bag 12 is disposed forward in the winding direction D2, and the bottom seal 14 that forms the bottom of the packaging bag 12 is disposed backward in the winding direction D2. The space between the bottom seal 14 and the perforation 13 of adjacent packaging bags 12 is the part that forms the so-called skirt 15 of the packaging bag 12, and the length of this portion is set appropriately, but the shorter the length, the better the yield.

また包装袋１２は横マチ付きであり、左右両側部には内側に折り込まれるマチ１６を有している。 The packaging bag 12 also has side gussets, with gussets 16 on both the left and right sides that can be folded inward.

このような連続型包装袋１１における包装袋１２は、その片面のミシン目１３における長手方向の一部に、破断されたミシン目を端に備える開封端緒１７を有している。開封端緒１７は、互いに接するフィルムのうち片面のフィルムにおける他方の面のフィルムとの密着が解かれた状態となっている部分である。開封端緒１７では、ミシン目１３の長手方向の一部が破断されることによって自由端ができ、他方の面のフィルから浮いたり、皺を有したりする外観となる。 The packaging bag 12 in this continuous type packaging bag 11 has an opening end 17 with a broken perforation at an end, along part of the longitudinal direction of the perforation 13 on one side. The opening end 17 is a part of one of the films that is in contact with the film on the other side where the adhesion has been released. At the opening end 17, a free end is created by breaking part of the longitudinal direction of the perforation 13, resulting in an appearance that floats from the fill on the other side or has wrinkles.

前述のように連続型包装袋１１の包装袋１２は底が引き出し方向Ｄ１に向けられた姿勢であるので、開封端緒１７は、ミシン目１３の引き出し方向Ｄ１側の部分に形成されることになる。 As described above, the bottom of the packaging bag 12 of the continuous packaging bag 11 faces the pull-out direction D1, so the opening edge 17 is formed in the part of the perforation 13 on the pull-out direction D1 side.

開封端緒１７はミシン目１３の長手方向の中間位置に形成される。開封端緒１７の範囲は適宜設定し得るが、左右のマチ１６よりも内側であるのが好ましい。 The opening edge 17 is formed at the longitudinal center of the perforation 13. The range of the opening edge 17 can be set as appropriate, but it is preferable that it is inside the left and right gussets 16.

この例において開封端緒１７が形成されるのは、ロール内面に位置するミシン目１３であり、このことによって開封端緒１７はロール状に巻かれた状態において外面に露出することなく内側に収まることになる。 In this example, the opening end 17 is formed by the perforations 13 located on the inner surface of the roll, so that the opening end 17 remains inside the roll without being exposed to the outside.

このような構成の連続型包装袋１１は、図２に示したように製造される。 A continuous packaging bag 11 having such a configuration is manufactured as shown in Figure 2.

ガゼット付きのチューブ１１ａをその長手方向に搬送しながら所定間隔おきに底シール１４を形成する溶着と、ミシン目１３を形成するミシン目形成を行う。図２中、２１は溶着機であり、２１ａはその受け台、２１ｂは上下動可能に設けられたシールバーである。また２２はミシン目形成機であり、２２ａはその受け台、２２ｂは上下動可能に設けられたミシン目形成刃である。 While transporting the gusseted tube 11a in its longitudinal direction, welding is performed at predetermined intervals to form the bottom seal 14, and perforation is performed to form the perforation 13. In FIG. 2, 21 is a welding machine, 21a is a receiving stand, and 21b is a seal bar that is movable up and down. Also, 22 is a perforation forming machine, 22a is a receiving stand, and 22b is a perforation forming blade that is movable up and down.

ミシン目１３と底シール１４を形成したのち、包装袋１２の片面におけるミシン目１３部分に、ミシン目１３を破断する方向の負荷を与えてミシン目１３における長手方向の一部を破断して、破断されたミシン目１３を端に備える開封端緒１７を形成する。開封端緒１７の形成後に、完成した連続型包装袋１１をロール状に巻き取る。図２中、２３は巻取り軸である。 After forming the perforations 13 and bottom seal 14, a load is applied to the perforations 13 on one side of the packaging bag 12 in a direction that breaks the perforations 13, breaking a portion of the perforations 13 in the longitudinal direction to form an opening end 17 with the broken perforations 13 at its end. After the opening end 17 is formed, the completed continuous packaging bag 11 is wound up into a roll. In FIG. 2, 23 is a winding shaft.

ミシン目１３の部分的な破断は、様々な構成で行い得るが、例えば次のような構成で行うとよい。 Partial breaking of the perforation 13 can be achieved in various configurations, but for example, it is preferable to achieve this in the following configuration.

すなわち、ミシン目破断機２４は、チューブ１１ａの下でチューブ１１ａを搬送方向における送りローラ２４ａと、チューブ１１ａ上で送りローラ２４ａに向けて往復動する接触ローラ２４ｂで構成されている。送りローラ２４ａはチューブ１１ａの幅よりも長く形成されるが、接触ローラ２４ｂの長さはそれよりも短く、所望する開封端緒１７の大きさに応じて形成される。また送りローラ２４ａは搬送方向に回転する一方、接触ローラ２４ｂはそれとは反対方向に回転するように設定される。接触ローラ２４ｂは、例えばシリコーンゴムなど、チューブ１１ａに対して摩擦抵抗の高い材料で形成される。 That is, the perforation breaker 24 is composed of a feed roller 24a that is placed under the tube 11a in the transport direction of the tube 11a, and a contact roller 24b that reciprocates above the tube 11a toward the feed roller 24a. The feed roller 24a is formed to be longer than the width of the tube 11a, while the length of the contact roller 24b is shorter, and is formed according to the desired size of the opening end 17. In addition, while the feed roller 24a rotates in the transport direction, the contact roller 24b is set to rotate in the opposite direction. The contact roller 24b is formed of a material that has high friction resistance against the tube 11a, such as silicone rubber.

接触ローラ２４ｂの往復動のための機構は、例えばカムやクランク機構などでモータの回転運動を直線運動に変換する適宜の機構で構成する。 The mechanism for reciprocating the contact roller 24b is composed of an appropriate mechanism that converts the rotational motion of the motor into linear motion, such as a cam or crank mechanism.

チューブ１１ａの搬送中、図３に実線で示したように、送りローラ２４ａと接触ローラ２４ｂは共に回転している。送りローラ２４ａの上を、一つの包装袋１２となる部分の底シール１４と、これに続く別の包装袋１２となるミシン目１３が通過したときに、接触ローラ２４ｂを降下させてチューブ１１ａにおけるミシン目１３の搬送方向後ろ側に接触させる。 During the transport of the tube 11a, the feed roller 24a and the contact roller 24b rotate together, as shown by the solid lines in Figure 3. When the bottom seal 14 of one packaging bag 12 and the perforation 13 of the subsequent packaging bag 12 pass over the feed roller 24a, the contact roller 24b is lowered to contact the rear side of the perforation 13 in the tube 11a in the transport direction.

接触ローラ２４ｂの接触と、接触ローラ２４ｂの搬送方向とは反対方向への回転により、搬送中のチューブ１１ａにおけるミシン目１３部分に負荷がかかり、ミシン目１３は破断する。ミシン目１３の破断と接触ローラ２４ｂの回転によって、ミシン目１３の搬送方向後ろ側の部分は、仮想線で示したように皺が寄るような態様になり、密着していた対向側フィルムとの間に隙間ができる。いったん降下させた接触ローラ２４ｂは、すぐさま上昇させる。 The contact of the contact roller 24b and its rotation in the opposite direction to the transport direction places a load on the perforation 13 in the tube 11a being transported, causing the perforation 13 to break. The breakage of the perforation 13 and the rotation of the contact roller 24b causes the rear portion of the perforation 13 in the transport direction to wrinkle as shown by the imaginary line, creating a gap between it and the opposing film that was in close contact with it. The contact roller 24b, which has been lowered once, is then immediately raised.

次々に形成されるミシン目１３の一部には、このような接触ローラ２４ｂの間欠動作によって、開封端緒１７が形成される。 The intermittent operation of the contact roller 24b forms an opening edge 17 in some of the successively formed perforations 13.

ミシン目１３の破断に際して、ミシン目１３の巻取り方向Ｄ２のすぐ隣であって接触ローラ２４ｂの回転方向上流側には、底シール１４が形成されているので、破断のための負荷がかかる部分におけるフィルムの延びを抑制でき、ミシン目１３は確実に破断される。 When the perforation 13 breaks, the bottom seal 14 is formed immediately adjacent to the perforation 13 in the winding direction D2 and upstream in the rotation direction of the contact roller 24b, so that the stretching of the film in the area where the load for breaking is applied can be suppressed, and the perforation 13 is broken reliably.

このあと、巻取り軸２３で巻取りがなされると、連続型包装袋１１の開封端緒１７はロール内面に収まり、開封端緒１７の自由端は保持される。開封端緒１７を有していても、巻取り時においては左右両側部のマチ１６がしっかりとした巻取りを可能にする。 After this, when the continuous packaging bag 11 is wound up on the winding shaft 23, the opening end 17 of the continuous packaging bag 11 fits inside the roll, and the free end of the opening end 17 is held in place. Even though the opening end 17 is included, the gussets 16 on both the left and right sides allow for secure winding.

以上のように製造された連続型包装袋１１は、サッカー台等に備えられる既存のロールホルダに取り付けられたり、箱に引き出し可能に収納されたりして使用される。 The continuous packaging bag 11 manufactured in the above manner can be used by attaching it to an existing roll holder provided on a soccer table or the like, or by storing it in a box so that it can be pulled out.

図４に連続型包装袋１１を下方に引き出した状態を示している。なお、図４では、連続型包装袋１１の先端部を単に垂らした状態を示したが、一般的なホルダに保持させると、ロールからの引き出し端部は手前側に位置させられる。 Figure 4 shows the continuous packaging bag 11 pulled downward. Note that in Figure 4, the leading end of the continuous packaging bag 11 is simply hanging down, but when held in a general holder, the end pulled out from the roll is positioned toward the front.

底シール１４を先頭に引き出される連続型包装袋１１は、包装袋１２の上端であるミシン目１３があらわれるまで引き出すと、そのミシン目１３の長手方向の中間に開封端緒１７が露出する。開封端緒１７は対向するフィルムに対して密着しておらず、開きやすい状態である。このため、仮想線で示したように開封端緒１７をつまんで包装袋１２を引っ張ると、ミシン目１３が破れて上端全体が開口しつつ包装袋１２を分離できる。 When the continuous packaging bag 11 is pulled out starting from the bottom seal 14 and is pulled out until the perforation 13 at the top of the packaging bag 12 appears, the opening edge 17 is exposed in the middle of the longitudinal direction of the perforation 13. The opening edge 17 is not in contact with the opposing film and is in an easy-to-open state. Therefore, when the opening edge 17 is pinched and the packaging bag 12 is pulled as shown by the phantom line, the perforation 13 breaks, opening the entire top end and allowing the packaging bag 12 to be separated.

分離された包装袋１２は開口しているので、あえて口をあける作業は必要なく、商品等を入れる作業が簡易迅速に行える。 The separated packaging bag 12 is open, so there is no need to open it, and putting products inside can be done quickly and easily.

開封端緒１７はミシン目１３の長手方向の中間位置に形成されているので、左右のいずれか一方に偏って形成されている場合と比較して、開口と切離しが安定して行える。 The opening edge 17 is formed in the middle of the longitudinal direction of the perforation 13, so opening and tearing can be performed more stably than if it were formed biased to either the left or right.

また開封端緒１７はロール内面に位置するミシン目１３に形成されているので、巻取り状態において開封端緒１７の露出を防げる。このため、不測に破れたりすることを防止し、無駄なく正しい使用が可能である。 In addition, the opening end 17 is formed at the perforation 13 located on the inner surface of the roll, so the opening end 17 is prevented from being exposed when the roll is wound up. This prevents accidental tearing and allows for proper use without waste.

包装袋１２はすべて同一姿勢であるとともに、包装袋１２の底が引き出し方向Ｄ１に向けられているので、開封端緒１７を有していても、連続型包装袋１１を引き出した状態において包装袋１２が開口することはなく、包装袋１２の衛生状態を維持できる。 Since all the packaging bags 12 are in the same position and the bottoms of the packaging bags 12 are oriented in the pulling-out direction D1, even if they have an opening end 17, the packaging bags 12 will not open when the continuous packaging bag 11 is pulled out, and the hygienic state of the packaging bags 12 can be maintained.

また包装袋１２は横マチ付きであるので、開封端緒１７を有していても左右両側部でしっかりした密な巻取りができるので、外観も良好で使いやすい連続型包装袋１１となる。 In addition, since the packaging bag 12 has a side gusset, even though it has an opening end 17, it can be tightly rolled up on both the left and right sides, resulting in a continuous packaging bag 11 that has a good appearance and is easy to use.

連続型包装袋１１の製造は、既存の方法でミシン目１３と底シール１４を形成したのち、ミシン目１３の一部を破断するだけでよいので、装置の構成を簡素にできるとともに、従来のように孔をあける場合とは異なり、製造工程でのゴミの発生をなくすこともできる。 The continuous packaging bag 11 can be manufactured by forming the perforations 13 and bottom seal 14 using existing methods, and then simply breaking off part of the perforations 13, which simplifies the device configuration and, unlike conventional methods that require punching holes, also eliminates the generation of waste during the manufacturing process.

以上の構成はこの発明を実施するための一形態であって、この発明は前述の構成のみに限定されるものではなく、その他の構成を採用することもできる。 The above configuration is one embodiment of the present invention, and the present invention is not limited to the above configuration, and other configurations may also be adopted.

以下、他の例に係る連続型包装袋１１を説明する。この説明において前述の構成と同一の構成については同一の符号を付してその詳しい説明を省略する。 The following describes another example of a continuous packaging bag 11. In this description, the same components as those described above are given the same reference numerals and detailed descriptions are omitted.

図５は他の例に係る連続型包装袋１１の斜視図である。この図に見られるように、開封端緒１７はロール外面に存在している。つまり、図５の連続型包装袋１１は、開封端緒１７をロール外面に位置するミシン目１３に形成した構成である。製造工程において、開封端緒１７の向きをロール外面に向けて巻き取る以外は、前述の構成と同じである。 Figure 5 is a perspective view of another example of a continuous packaging bag 11. As can be seen in this figure, the opening end 17 is present on the outer surface of the roll. In other words, the continuous packaging bag 11 in Figure 5 has a configuration in which the opening end 17 is formed at the perforation 13 located on the outer surface of the roll. In the manufacturing process, the bag is wound up with the opening end 17 facing the outer surface of the roll, and the configuration is the same as that described above.

このような構成の連続型包装袋１１では、引き出し先端側の包装袋１２が静電気によってロールに密着している状態であっても、包装袋１２を取るときに図５に仮想線で示したようにロールの外面に沿って指を動かせば、指先が開封端緒１７を捉える。このため、容易に包装袋１２の開口と分離ができる。また、包装袋１２の開口と分離は、ロールを回して引き出し先端側の包装袋１２を引き出さなくても行える。 In a continuous packaging bag 11 configured in this way, even if the packaging bag 12 at the leading end is stuck to the roll due to static electricity, when removing the packaging bag 12, the fingertip can catch the opening edge 17 by moving the finger along the outer surface of the roll as shown by the phantom lines in Figure 5. This makes it easy to open and separate the packaging bag 12. In addition, the packaging bag 12 can be opened and separated without turning the roll to pull out the packaging bag 12 at the leading end.

そのほか、図示は省略するが、例えば開封端緒１７の形成は、接触ローラ２４ｂに代えて、送りローラ２４ａに向けて移動する方向に間欠動作するハンマーのような回転しない構成を使用してもよい。 In addition, although not shown in the figures, for example, the opening end 17 may be formed using a non-rotating structure such as a hammer that moves intermittently in the direction of movement toward the feed roller 24a, instead of the contact roller 24b.

また、包装袋１２はマチ１６のない形態でも、サイドシール型のものでもよい。 The packaging bag 12 may also be of a type without a gusset 16 or of a side-seal type.
