Description

本発明は、包装袋に係り、例えば、菓子や果実等の食品類その他を収納して封緘できるようにした包装袋に関する。 The present invention relates to a packaging bag, for example, a packaging bag that can store and seal foods such as confectionery and fruits.

デパートやスーパー等の食品売場では、菓子や果実等の食品類が透明な包装袋に収納されて展示販売されることが多い。このような包装袋は、例えば、図５に示すように、下部で連なる表裏２枚の合成樹脂フィルム１１，１２の上部が方形状に形成され、食品等を収納した状態で、その上部開口を剥離紙付きの封緘用両面テープ１３で封緘できるようにしたものが公知である。この場合、２枚の合成樹脂フィルム１１，１２の両側部及び底ガゼット１４の両側部が溶着ｈされている。なお、内部に収納した乾燥食品を水や湯を注入して復元できるようにした包装袋も提案されている（例えば、特許文献１参照）。 In food departments such as department stores and supermarkets, foods such as confectionery and fruits are often stored and displayed in transparent packaging bags. For example, as shown in FIG. 5, such a packaging bag is formed in a rectangular shape at the top of two synthetic resin films 11, 12 that are connected at the bottom, and the upper opening is opened in a state where food or the like is stored. A device that can be sealed with a double-sided sealing tape 13 with release paper is known. In this case, both sides of the two synthetic resin films 11 and 12 and both sides of the bottom gusset 14 are welded h. A packaging bag has also been proposed in which dry food stored inside can be restored by pouring water or hot water (see, for example, Patent Document 1).

このような包装袋では、内部に食品等を収納した後は、手作業で剥離紙を剥がして封緘していたが、上記図５に示す従来例のように、袋本体の上部が方形状に形成されていると、上部開口を封緘する際に、両面テープ１３の剥離紙を剥がすために隅部に指を入れなければならず、その剥がし作業が容易でなく封緘作業が煩瑣になるという問題があった。また、封緘された状態では、両面テープ１３によって上部開口が両端まで閉じられているため、開封しにくいという難点もあった。 In such a packaging bag, after food or the like was stored inside, the release paper was manually peeled off and sealed, but the upper portion of the bag body was rectangular as in the conventional example shown in FIG. If formed, when sealing the upper opening, a finger must be put in the corner to peel off the release paper of the double-sided tape 13, and the peeling work is not easy and the sealing work becomes troublesome. was there. Moreover, in the sealed state, since the upper opening was closed to both ends by the double-sided tape 13, there also existed a difficulty that it was hard to open.

そして、食品を内部に収納した封緘状態では、果実等を収納する場合、その上部両側隅部に食品を収納できない空間部分が残って嵩高くなり充填効率（全内容積に対する実際に収納できる容積の割合）が低いという難点があった。食品売場では、できるだけ多くの包装袋を見映えよく展示できることが望ましく充填効率の高い包装袋が求められるが、上述のように、食品を収納できない両側空間部分が角張って張り出していると見映えがよくないという問題もあった。 In the sealed state in which food is stored inside, when storing fruits, etc., space portions that cannot store food remain at the upper side corners, resulting in a bulky filling efficiency (of the volume that can be actually stored relative to the total internal volume). The ratio) was low. In food departments, it is desirable to display as many packaging bags as possible and to display them as much as possible. Packaging bags with high filling efficiency are required. However, as described above, if both sides of the space where food cannot be stored are squared and projected, There was also a problem that it was not good.

さらに、このような包装袋では、使用する前には、多数枚を積み重ねて束にした状態で搬送したり保管したりするため、積み重ねた状態においてもできるだけ嵩張らないことが望まれる。しかるに、従来の包装袋のように袋本体が矩形状に形成されていると、積み重ねて束にしても角部が張り出すため、取り扱いにくく、また、保管時にスペースを要するという難点があった。 Furthermore, since such a packaging bag is transported or stored in a state where a large number of sheets are stacked and bundled before use, it is desired that the packaging bag is not as bulky as possible even in the stacked state. However, when the bag body is formed in a rectangular shape as in a conventional packaging bag, the corners protrude even when they are stacked and bundled.

本発明は、このような実情に鑑みてなされ、上部開口を封緘する際に剥離紙を剥がしやすく、かつ、開封が容易であり、また、袋内に物品を収納した状態では、嵩張ることなく見映えが良好であり、また、多数枚を積み重ねて束にした状態でも取り扱いやすく、保管時のスペースが少なくて済む包装袋を提供することを目的とする。 The present invention has been made in view of such circumstances, and when sealing the upper opening, the release paper can be easily peeled off and easily opened, and when the article is stored in the bag, it is not bulky. An object of the present invention is to provide a packaging bag which has good shine, is easy to handle even in a state where a large number of sheets are stacked and bundled, and requires less space for storage.

本発明の包装袋は、下部で連なる表シート１と裏シート２の上辺部３の両側にそれぞれ斜め内向きのテーパー状に形成されたテーパー辺４，４が形成され、前記表シート１と裏シート２の前記テーパー辺４，４を除いた両側部５，５が溶着ｈされ、かつ、上部に開口６が形成される包装袋であって、
前記表シート１又は裏シート２の前記テーパー辺４，４間における上辺部３の内側には、剥離紙付きの封緘用両面テープ７が貼着され、該封緘用両面テープ７で前記表シート１と裏シート２の上辺部３が接着されて前記開口６が封緘された状態では、前記テーパー辺４，４の前記封緘用両面テープ７より下方の部分が開放状態となり、該下方の開放部分から前記封緘された状態の開口６が開封可能に構成されていることを特徴とする。
In the packaging bag of the present invention, tapered sides 4 and 4 are formed on the both sides of the upper side 3 of the front sheet 1 and the back sheet 2 which are continuous at the lower part, respectively, and are formed in an obliquely inwardly tapered shape. A packaging bag in which both side portions 5 and 5 excluding the taper sides 4 and 4 of the sheet 2 are welded h, and an opening 6 is formed in the upper portion,
On the inner side of the upper side 3 between the tapered sides 4, 4 of the front sheet 1 or the back sheet 2, a double-sided sealing tape 7 with release paper is stuck, and the double-sided tape 7 for sealing is used to attach the front sheet 1. and in the state in which the opening 6 upper part 3 of the backing sheet 2 is bonded is sealed, the tapered sides said sealing double-sided tape 7 from the lower portion of the 4,4 open and Do Ri, opening of said lower The opening 6 in the sealed state from the portion is configured to be openable .

このような構成によれば、テーパー辺４，４は溶着されていないため、封緘前に、両テーパー４，４辺間に貼着された封緘用両面テープ７の剥離紙の端部を容易に掴んで剥がすことができるため、封緘作業が容易となる。また、物品を袋内に収納した状態でも両テーパー辺４，４の封緘用両面テープ７より下方の部分が開放されているため、その開放部分から封緘された状態の開口６を容易に開封することができる。そして、物品を袋内に収納した状態では、上辺部３の両側にテーパー辺４，４が形成されていることによって角部が張り出して嵩張るようなことがなく見映えが良好となり、充填効率も高くなる。さらに、使用前に多数枚を積み重ねて束にした状態でも角部の張り出しがなく嵩張らないため、取り扱いやすく、保管時のスペースが少なくて済む。
According to such a configuration, since the taper sides 4 and 4 are not welded, the end portion of the release paper of the double-sided tape 7 for sealing adhered between both taper 4 and 4 sides can be easily formed before sealing. Since it can be grasped and peeled off, the sealing work becomes easy. Further, even when the article is stored in the bag, the portion below the double-sided sealing tape 7 with both tapered sides 4 and 4 is opened, so that the opening 6 sealed from the opened portion is easily opened. be able to. And in the state which accommodated the goods in the bag, since the taper sides 4 and 4 are formed in the both sides of the upper side part 3, a corner | angular part does not protrude and it becomes bulky, and it looks good, and filling efficiency is also good Get higher. Further, even when a large number of sheets are stacked and bundled before use, the corners do not protrude and are not bulky. Therefore, handling is easy and space for storage is small.

このような包装袋では、前記表シート１と裏シート２の下部には、底ガゼット８が形成されてもよい。このようにすれば、物品の収納量が多くなる。 In such a packaging bag, a bottom gusset 8 may be formed under the front sheet 1 and the back sheet 2. In this way, the amount of articles stored increases.

本発明の包装袋は、表シート又は裏シートの前記テーパー辺間における上辺部の内側に剥離紙付きの封緘用両面テープを貼着しているので、封緘前に、両面テープの剥離紙の端部を容易に掴んで剥がすことができるため、封緘作業が容易となる。また、物品を袋内に収納して開口が封緘された状態では、テーパー辺の封緘用両面テープより下方の部分が開放されているため、その部分から容易に開封することができる。そして、物品を袋内に収納した状態では、上辺部の両側のテーパー辺によって角部が張り出して嵩張るようなことがなく見映えが良好となり、充填効率も高くなる。さらに、使用前に多数枚を積み重ねて束にした状態でも角部の張り出しがなく嵩張らないため、取り扱いやすく、保管時のスペースが少なくて済む。 Since the packaging bag of the present invention has a double-sided sealing tape with release paper attached to the inside of the upper side between the tapered sides of the front sheet or back sheet, the end of the release paper of the double-sided tape before sealing Since the part can be easily grasped and peeled off, the sealing work becomes easy. Further, in a state where the article is stored in the bag and the opening is sealed, the portion below the double-sided tape for sealing on the taper side is opened, so that it can be easily opened from that portion. And in the state which accommodated the goods in the bag, a corner | angular part does not protrude and it becomes bulky by the taper side of the both sides of an upper side part, and it looks good, and filling efficiency also becomes high. Further, even when a large number of sheets are stacked and bundled before use, the corners do not protrude and are not bulky. Therefore, handling is easy and space for storage is small.

以下に、本発明の最良の実施の形態に係る包装袋について図面を参照しつつ詳細に説明する。図１は包装袋の正面図、図２は斜視図、図３は展開図、図４は内部に食品を収容した状態の斜視図である。これらの図にて、符号１は表シート、２は裏シートで、この表シート１と裏シート２は下部で連なっている。３は上辺部、４はテーパー辺で、上辺部３の両側にそれぞれ内向きのテーパー状に形成される。そして、表シート１と裏シート２のテーパー辺４，４を除いた両側部５，５が溶着ｈされ、かつ、上部には開口６が形成される。 Below, the packaging bag which concerns on the best embodiment of this invention is demonstrated in detail, referring drawings. 1 is a front view of a packaging bag, FIG. 2 is a perspective view, FIG. 3 is a development view, and FIG. 4 is a perspective view of a state in which food is contained.

Reference numeral 3 denotes an upper side portion, and 4 denotes a tapered side, which are formed on both sides of the upper side portion 3 in an inwardly tapered shape. And both the side parts 5 and 5 except the taper sides 4 and 4 of the front sheet | seat 1 and the back sheet | seat 2 are welded h, and the opening 6 is formed in the upper part.

このような包装袋にあって、表シート１又は裏シート２のテーパー辺４，４間における上辺部３の内側には、剥離紙付きの封緘用両面テープ７が貼着され、かつ、表シート１と裏シート２の下部には底ガゼット８が形成される。そして、内部に物品（例えば、果実等）９が収納されて封緘用両面テープ７で表シート１と裏シート２の上辺部３が接着されて開口６が封緘された状態では、テーパー辺４，４の封緘用両面テープ７より下方の部分が開放状態となる（図３参照）。なお、１０は空気抜きの孔である。 In such a packaging bag, a sealing double-sided adhesive tape 7 with release paper is attached to the inside of the upper side 3 between the tapered sides 4 and 4 of the front sheet 1 or the back sheet 2, and the front sheet A bottom gusset 8 is formed at the bottom of 1 and the back sheet 2. When the article (for example, fruit) 9 is housed inside and the upper side 3 of the front sheet 1 and the back sheet 2 is bonded with the double-sided tape 7 for sealing and the opening 6 is sealed, the taper side 4, The part below the double-sided sealing double-faced tape 7 is open (see FIG. 3). Reference numeral 10 denotes an air vent hole.

包装袋の製造方法については、例えば、二軸延伸ポリプロピレンと無延伸ポリプロピレンとを貼り合わせた４０μｍ厚の巻取り原反から繰り出した帯状のフィルムを、図３に示すように、表シート１と裏シート２の間にＷ字形状の切込みを形成した底ガゼット８を形成した形状に切断し、表シート１と裏シート２の両側部と、底ガゼット８の周縁部と、をそれぞれ溶着すればよい。また、表シート１と裏シート２及び底ガゼット８をそれぞれ別体に切断し、底ガゼット８を台形状に折り畳んで、表シート１と裏シート２の間に挿入して、表シート１と裏シート２の両側部と、底ガゼット８の周縁部と、をそれぞれ溶着してもよい。なお、本発明は、包装袋の製造方法を特定するものではなく、その他の適宜な方法でせいそうされてもよい。 As for the manufacturing method of the packaging bag, for example, as shown in FIG. 3, the front sheet 1 and the back side of the belt-shaped film unwound from a 40 μm-thick winding raw fabric in which biaxially stretched polypropylene and unstretched polypropylene are bonded The bottom gusset 8 in which a W-shaped cut is formed between the sheets 2 is cut into a shape, and both side portions of the front sheet 1 and the back sheet 2 and the peripheral edge portion of the bottom gusset 8 are welded to each other. . Further, the front sheet 1, the back sheet 2 and the bottom gusset 8 are cut into separate bodies, the bottom gusset 8 is folded into a trapezoidal shape, and inserted between the front sheet 1 and the back sheet 2, and the front sheet 1 and the back sheet You may weld both the side parts of the sheet | seat 2, and the peripheral part of the bottom gusset 8, respectively. In addition, this invention does not specify the manufacturing method of a packaging bag, and may be tempted by another appropriate method.

このような構成によれば、テーパー辺４，４は溶着されていないため、両テーパー４，４辺間に貼着された封緘用両面テープ７の剥離紙の端部を容易に掴んで剥がすことができるため、封緘作業が容易となる。また、物品９を袋内に収納した状態でも、図４に示すように、両テーパー辺４，４が開放されているため、その部分から容易に開封することができる。そして、このように物品を収納した状態では、上辺部３の両側にテーパー辺４，４が形成されていることによって角部が張り出して嵩張るようなことがなく見映えが良好となり、充填効率も向上する。さらに、角部の張り出しがなく嵩張らないため、使用前に、多数枚を積み重ねて束にした状態でも取り扱いやすく、保管時のスペースが少なくて済む。また、下部に底ガゼット８が形成されているので、物品９の収納量が多くなる。 According to such a configuration, since the taper sides 4 and 4 are not welded, the end of the release paper of the double-sided tape 7 for sealing adhered between both tapers 4 and 4 is easily grasped and peeled off. Therefore, sealing work becomes easy. Further, even when the article 9 is housed in the bag, as shown in FIG. 4, since both the tapered sides 4 and 4 are opened, it can be easily opened from that portion. And in the state which accommodated the article | item in this way, since the taper edge | sides 4 and 4 are formed in the both sides of the upper edge part 3, a corner | angular part does not protrude and it becomes bulky, and it looks good, and filling efficiency is also good. improves. Furthermore, since the corners do not protrude and are not bulky, it is easy to handle even in a state where a large number of sheets are stacked and bundled before use, and the space for storage can be reduced. Moreover, since the bottom gusset 8 is formed in the lower part, the storage amount of the article 9 is increased.
