Description

開封片付き包装体Package with opening piece
　本発明は、開封片が包装体に接合されている開封片付き包装体および当該開封片に関する。 The present invention relates to a package with an opening piece in which the opening piece is joined to the package, and the opening piece.
　ソーセージ等の内容物が密封された包装体は、一般的に、筒状に貼り合わせた包装フィルムに内容物を充填した後に、上下端を収束し結紮することによって製造されている。このような包装体の開封を容易にするために、小さなフィルムで形成された開封片を包装体に溶着することがある。 A package body in which contents such as sausage are sealed is generally manufactured by filling the contents in a packaging film bonded in a cylindrical shape and then converging and ligating the upper and lower ends. In order to facilitate the opening of such a package, an unsealed piece formed of a small film may be welded to the package.
　図８に、開封片が包装体に溶着されている開封片付き包装体の一部分を示す正面図を示す。図８に示すように、開封片１２は、包装体１１の胴周方向に延びる直線状の溶着部１３で溶着されているのが一般的である（特許文献１および２）。 FIG. 8 is a front view showing a part of the package with an open piece in which the open piece is welded to the package. As shown in FIG. 8, the opening piece 12 is generally welded by a linear welded portion 13 extending in the body circumferential direction of the package 11 (Patent Documents 1 and 2).
　この開封片１２をつまんで包装体１１の胴周方向にめくると溶着部１３が起点となり、包装フィルムに線状の切れ目を与える。その後、切れ目の上方に位置する結紮部１４をつまみ、開封片付き包装体２０の後方に引き下げることにより、上述の線状の切れ目がきっかけとなり包装フィルムが包装体１１の胴周方向に開裂する。包装フィルムの開裂が包装フィルムを筒状に貼り合わせている部分に到達すると、その部分に沿って内容物が露出し、開封片付き包装体２０の開封に至る。 When the opening piece 12 is pinched and turned in the body circumferential direction of the package body 11, the welded portion 13 becomes a starting point, and a linear cut is given to the packaging film. Thereafter, the ligature portion 14 located above the cut is pinched and pulled down to the rear of the package 20 with the unsealed piece, whereby the above-described linear cut is triggered and the packaging film is split in the body circumferential direction of the package 11. When the wrapping of the packaging film reaches the part where the packaging film is bonded in a cylindrical shape, the contents are exposed along the part, and the package 20 with the opening piece is opened.

　特許文献１および２に開示されているような開封片付き包装体では、開封片をつまんで胴周方向にめくって剥がすことにより、包装フィルムの開裂のきっかけとなる線状の切れ目を包装フィルムにつける工程と、線状の切れ目の上方に位置する結紮部をつまんで開封片付き包装体の後方に引き下げて内容物を露出する工程との２つの行程を要する。そのため、開封片付き包装体を開封するために手間がかかる上に、剥がした開封片を廃棄するための手間もかかる。 In a package with an open piece as disclosed in Patent Documents 1 and 2, a linear cut that triggers the tear of the packaging film is made on the packaging film by pinching the open piece and peeling it off in the circumferential direction of the trunk. Two steps of a process and the process of pinching the ligature part located above a linear cut | interruption and pulling it back behind a package body with an open piece, and exposing the contents are required. Therefore, it takes time to open the package with the opening pieces, and also takes time to discard the peeled opening pieces.
　また、上記の２つの工程は、消費者にとっては分かり難く、消費者は開封片付き包装体の開封方法を直感的に理解することが難しい。 Also, the above two steps are difficult for the consumer to understand, and it is difficult for the consumer to intuitively understand how to open the package with the open piece.
　そこで、本発明は、上述の問題に鑑みてなされたものであり、その目的は、より容易に開封することができる開封片付き包装体を提供することにある。 Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a package with an opening piece that can be opened more easily.
　上記の課題を解決するために、本発明の一態様に係る開封片付き包装体は、筒状に形成した包装フィルムの内部に内容物を充填し、両端を閉じて形成された包装体と、上記包装体と接合している接合部を有する開封片と、を備え、上記接合部は、上記開封片を所定方向に剥がすことによって、上記包装フィルムを面状に裂くことの起点となる第１接合部と、上記第１接合部よりも上記所定方向の下流側に位置し、上記開封片を上記所定方向に剥がした際に上記第１接合部によって面状に裂かれた上記包装フィルムが到達すると、面状に裂かれる上記包装フィルムの胴周方向の幅をさらに広げることの起点となる第２接合部と、を含む構成を有している。 In order to solve the above-described problem, a package with an unsealed piece according to one aspect of the present invention is a package formed by filling the inside of a packaging film formed in a cylindrical shape and closing both ends, An opening piece having a bonding portion bonded to the package body, and the bonding portion is a first bonding that is a starting point for tearing the packaging film into a planar shape by peeling the opening piece in a predetermined direction. And the packaging film that is located downstream of the first joint portion in the predetermined direction and is torn in a planar shape by the first joint portion when the opening piece is peeled off in the predetermined direction. And a second joint that is a starting point for further expanding the width of the packaging film in the circumferential direction of the packaging film that is torn into a planar shape.
　上記の構成によれば、開封片が第１接合部を有しているため、本発明の一態様に係る開封片付き包装体の開封時に開封片を剥がす際には、まず第１接合部によって包装フィルムが面状に裂かれ、その状態で第２接合部において包装フィルムの裂開が行われる。このように、本発明の一態様に係る開封片付き包装体では、開封片を剥がす際、包装フィルムの裂開が段階的に行われるため、第２接合部において包装フィルムを面状に裂くことができる。 According to said structure, since an opening piece has a 1st junction part, when peeling an opening piece at the time of opening of the package with an opening piece which concerns on 1 aspect of this invention, it is packaged by a 1st junction part first. The film is torn into a planar shape, and the packaging film is cleaved at the second joint in this state. Thus, in the package with an open piece according to one embodiment of the present invention, when the open piece is peeled off, the tear of the packaging film is performed stepwise, and therefore the packaging film can be split into a planar shape at the second joint portion. it can.
　裂かれた包装フィルムをさらに開封片付き包装体の後方に引き下げていくことにより、包装フィルムを筒状に貼り合わせている部分に沿って包装フィルムが開裂していき、開封片付き包装体を開封することができる。この際、第２接合部によって、面状に裂かれる包装フィルムの胴周方向の幅が広がるため、裂かれた包装フィルムを開封片付き包装体の後方に引き下げる際に容易に包装フィルムを包装体の胴周方向に開裂させることができ、より容易に開封片付き包装体を開封することができる。 By further lowering the torn packaging film to the rear of the package with the opening piece, the packaging film is torn along the portion where the packaging film is bonded to the cylinder, and the package with the opening piece is opened. Can do. At this time, since the width in the circumferential direction of the packaging film that is torn into a plane is widened by the second joint portion, the packaging film can be easily attached to the packaging body when the torn packaging film is pulled down to the back of the packaging body with the opening piece. The package body can be cleaved in the circumferential direction, and the package with the unsealed piece can be opened more easily.
　本発明の一態様によれば、開封片付き包装体をより容易に開封することができる。 According to one aspect of the present invention, the package with an opening piece can be opened more easily.

　［包装体］
　包装体１は、内容物を内部に密封しているものである。包装体１は、帯状の包装フィルムを筒状に巻き、長手方向Ｙに延びる両側辺を重ね合わせ、重ね合わせた両側辺を溶着することにより筒状形状を形成した後、その内部に内容物を充填し、上下端を結紮部４によって閉じて形成されている。 [Packaging]
The package 1 has the contents sealed inside. The packaging body 1 is formed by winding a belt-shaped packaging film in a cylindrical shape, superimposing both sides extending in the longitudinal direction Y, and welding the overlapped sides to form a cylindrical shape. It is filled and the upper and lower ends are closed by the ligation part 4.
　包装フィルムの両側辺の重ね合わせは、包装フィルムの長手方向に延びる一方の側辺の表（おもて）面と、他方の側辺の裏面とを重ね合わせる封筒貼り、および包装フィルムの長手方向に延びる両側辺の表面同士または裏面同士を重ね合わせる合掌貼りのいずれの方法で重ね合わせてもよい。 The overlapping of both sides of the packaging film is performed by attaching an envelope that superimposes the front surface of one side extending in the longitudinal direction of the packaging film and the back surface of the other side, and the longitudinal direction of the packaging film.

　包装フィルムとしては、高分子フィルムが好適に用いられる。高分子フィルムとしては、塩化ビニリデン系樹脂を用いることが好ましいが、これに限定されるものではない。これにより、包装フィルムを筒状形成する際に、包装フィルムの長手方向に延びる両側辺を熱溶着によって溶着させることができる。 A polymer film is preferably used as the packaging film. As the polymer film, a vinylidene chloride resin is preferably used, but is not limited thereto. Thereby, when forming a packaging film cylindrically, the both sides extended in the longitudinal direction of a packaging film can be welded by heat welding.
　包装体１に充填される内容物は、食用としての魚の肉である魚肉練り肉（魚肉練製品および魚肉ソーセージの原料）が主原料として好適に用いられる。また、獣肉用の練肉あるいはプロセスチーズ等であってもよい。なお包装体１に充填される内容物は、これらに限定されるものではない。 The contents filled in the package 1 are suitably used as a main raw material, which is a fish meat paste (a raw material for fish meat products and fish sausages) that is edible fish meat. Moreover, the meat for animal meat, process cheese, etc. may be sufficient. The contents filled in the package 1 are not limited to these.
　［開封片］
　開封片２は、開封フィルムによって形成されており、包装体１の開封を容易にするために包装体１に取り付けられた部材である。開封片２は、開封片２の接合部が包装体１に接合されていることにより包装体１に取り付けられている。なお、開封片２は、包装体１における重ね合わせを貼り合わせた部分に重ならないように、包装体１に取り付けられている。詳細は後述するが、本実施形態では、開封片２を剥離方向Ａ（所定方向）に剥がすことにより、開封片付き包装体１０を開封している。 [Opened piece]
The opening piece 2 is formed of an opening film, and is a member attached to the packaging body 1 for easy opening of the packaging body 1. The unsealed piece 2 is attached to the package 1 by joining the joint of the unsealed piece 2 to the package 1. In addition, the opening piece 2 is attached to the packaging body 1 so that it does not overlap with the part in which the overlapping in the packaging body 1 is bonded. Although details will be described later, in the present embodiment, the unwrapped package 10 is opened by peeling the unsealed piece 2 in the peeling direction A (predetermined direction).
　開封フィルムとしては、高分子フィルムが好適に用いられる。高分子フィルムとしては、包装フィルムと同様に塩化ビニリデン系樹脂を用いることが好ましいが、これに限定されるものではない。 A polymer film is preferably used as the opening film. As the polymer film, it is preferable to use a vinylidene chloride resin as in the case of the packaging film, but it is not limited to this.
　図１では、開封片２は矩形に形成されているが、開封片２を包装体１から剥がすことができる限り、その形状は特に制限されない。例えば、矩形以外にも、正方形、三角形および五角形等の多角形ならびに円形および楕円形等の形状に形成することができる。 1, the opening piece 2 is formed in a rectangular shape, but the shape is not particularly limited as long as the opening piece 2 can be peeled off from the package 1. For example, besides a rectangle, it can be formed in a polygon such as a square, a triangle, and a pentagon, and a shape such as a circle and an ellipse.
　［接合部］
　接合部は、開封片２において包装体１と接合している部分である。開封片２を包装体１に接合させる方法は、超音波溶着が好適に用いられるが、高周波溶着等の他の溶着方法を用いることもできる。また、開封片２を包装体１に接合させる方法は溶着に限定されず、接着等の方法を用いてもよい。 [Joint part]
The joint portion is a portion joined to the package 1 in the opening piece 2. Ultrasonic welding is suitably used as a method for joining the unsealed piece 2 to the package 1, but other welding methods such as high-frequency welding can also be used. Moreover, the method of joining the opening piece 2 to the package 1 is not limited to welding, and a method such as adhesion may be used.
　本実施形態において、接合部は、第１接合部３ａ、第２接合部３ｂおよび第３接合部３ｃを含んでいる。第１接合部３ａ、第２接合部３ｂおよび第３接合部３ｃは、それぞれ独立して包装体１と接合しており、各接合部は互いにつながっていない。 In this embodiment, the joint includes a first joint 3a, a second joint 3b, and a third joint 3c. The 1st junction part 3a, the 2nd junction part 3b, and the 3rd junction part 3c are each joined to the package 1 independently, and each junction part is not connected mutually.
　（第１接合部３ａ）
　第１接合部３ａは、開封片２を剥離方向Ａに剥がした際に、包装フィルムを面状に裂くことの起点となる接合部である。具体的には、第１接合部３ａは、開封片２を剥離方向Ａに剥がした際に、包装フィルムを面状に裂くことの起点となる切れ目を包装フィルムに与える接合部である。 (1st junction part 3a)
The 1st junction part 3a is a junction part used as the starting point of tearing a packaging film into planar shape, when peeling the opening piece 2 to the peeling direction A. As shown in FIG. Specifically, the 1st junction part 3a is a junction part which gives the cut | interruption which becomes a starting point of tearing a packaging film in planar shape, when peeling the opening piece 2 in the peeling direction A to a packaging film.
　図１では、第１接合部３ａは、逆三角形の形状を有しており、逆三角形の上辺の一部が内部に凹んでいる形状を有している。すなわち、第１接合部３ａは、底辺の一部が内部に凹んでいる三角形の形状を有しており、三角形の底辺が胴周方向Ｘに延び、当該底辺が開封片２の上端側に位置する形状を有している。第１接合部３ａでは、三角形の内部領域も含めて包装体１に接合していてもよいし、三角形の辺上だけ包装体１に接合していてもよい。 In FIG. 1, the 1st junction part 3a has a shape of an inverted triangle, and has a shape where a part of the upper side of the inverted triangle is recessed inside. That is, the first joint portion 3a has a triangular shape in which a part of the base is recessed inside, the base of the triangle extends in the trunk circumferential direction X, and the base is positioned on the upper end side of the opening piece 2 It has a shape to In the 1st junction part 3a, it may be joined to the package 1 including the triangular internal area | region, and may be joined to the package 1 only on the triangle side.
　なお、第１接合部３ａの三角形の底辺の一部が内部に凹んでいることにより、第１接合部３ａにおいて包装体１に接合する面積が小さくなるため、開封片２を包装体１に良好に接合させることができる。ただし、第１接合部３ａは、三角形の底辺の一部が内部に凹んでいない形状を有していてもよい。 In addition, since the area joined to the package 1 in the 1st junction part 3a becomes small because a part of the triangle base of the 1st junction part 3a is dented inside, the opening piece 2 is good for the package 1 Can be joined. However, the 1st junction part 3a may have the shape where a part of base of a triangle is not dented inside.
　ここで、第１接合部３ａの胴周方向Ｘの幅は、第２接合部３ｂの胴周方向Ｘの幅よりも小さいことが好ましい。第１接合部３ａが、第２接合部３ｂの胴周方向Ｘの幅よりも小さい幅を有していると、上述したように、第１接合部３ａにおいて包装体１に接合する面積が小さくなるため、開封片２を包装体１に良好に接合させることができる。 Here, the width in the trunk circumferential direction X of the first joint portion 3a is preferably smaller than the width in the trunk circumferential direction X of the second joint portion 3b. When the 1st junction part 3a has a width | variety smaller than the width | variety of the trunk | drum circumferential direction X of the 2nd junction part 3b, as above-mentioned, the area joined to the package 1 in the 1st junction part 3a is small. Therefore, the opening piece 2 can be favorably bonded to the package 1.
　（第２接合部３ｂ）
　第２接合部３ｂは、第１接合部３ａよりも剥離方向Ａの下流側に位置し、開封片２を剥離方向Ａに剥がした際に第１接合部３ａによって面状に裂かれた包装フィルムが到達すると、面状に裂かれる包装フィルムの胴周方向の幅をさらに広げることの起点となる接合部である。具体的には、第２接合部３ｂは、開封片２を剥離方向Ａに剥がした際に第１接合部３ａによって面状に裂かれた包装フィルムが到達すると、面状に裂かれる包装フィルムの胴周方向の幅をさらに広げることの起点となる切れ目を包装フィルムに与える接合部である。 (Second joint portion 3b)
The 2nd junction part 3b is located in the downstream of the peeling direction A rather than the 1st junction part 3a, and when the opening piece 2 was peeled in the peeling direction A, the packaging film which was torn by planar form by the 1st junction part 3a Is a joint that becomes a starting point for further expanding the width in the circumferential direction of the packaging film that is torn into a planar shape. Specifically, the second joint portion 3b is formed of a packaging film that is torn into a planar shape when the packaging film that is torn in a planar shape by the first joint portion 3a when the unsealed piece 2 is peeled in the peeling direction A. This is a joint that gives a cut to the packaging film as a starting point for further expanding the width in the waist circumference direction.
　図１では、第２接合部３ｂは、胴周方向Ｘに延びる線形状を有している。具体的には、第２接合部３ｂは、胴周方向Ｘに延びる直線部分を有しており、当該直線部分には、その両端から開封片２の上端側の２つの角それぞれに向かって延びる２つの斜線部分が形成されている。第２接合部３ｂでは、直線部分および斜線部分が包装体１に接合されている。 In FIG. 1, the second joint 3 b has a linear shape extending in the trunk circumferential direction X. Specifically, the 2nd junction part 3b has the linear part extended in the trunk | drum circumferential direction X, and the said linear part is extended toward each of two corners of the upper end side of the opening piece 2 from the both ends. Two hatched portions are formed. In the second joint portion 3b, the straight portion and the shaded portion are joined to the package 1.
　図１のように、第２接合部３ｂは、線形状を有していることが好ましい。これは、第２接合部３ｂが線形状を有していることにより、第２接合部３ｂにおける包装フィルムの裂開時に、面状に裂かれる包装フィルムの胴周方向の幅をさらに広げることの起点となる切れ目を包装フィルムに与えやすくなるためである。なお、線形状には、直線、曲線、弧線、波線またはジグザグ線等、種々の形状の線が含まれる。 As shown in FIG. 1, it is preferable that the 2nd junction part 3b has a linear shape. This is because, when the second joint 3b has a linear shape, the width in the circumferential direction of the packaging film that is torn into a planar shape at the time of tearing of the packaging film at the second joint 3b is further increased. It is because it becomes easy to give the cut | interruption used as the starting point to a packaging film. The line shape includes various shapes such as a straight line, a curved line, an arc line, a wavy line, or a zigzag line.
　なお、第２接合部３ｂの斜線部分は、開封片付き包装体１０をレトルト殺菌するレトルト工程、または開封片付き包装体１０を製造する包装工程等において開封片２がめくれてしまうことを抑制する機能を有している。 In addition, the hatched portion of the second joint portion 3b has a function of preventing the opening piece 2 from being turned over in a retorting process for retorting the packaging body 10 with the opening piece or a packaging process for manufacturing the packaging body 10 with the opening piece. Have.
　第２接合部３ｂの斜線部分は、それぞれ開封片２の上端側の角まで完全に到達していてもよいし、第２接合部３ｂの各斜線部分と開封片２の上端側の角との間に隙間が存在していてもよく、第２接合部３ｂの直線部分の両端から、当該直線部分よりも剥離方向Ａの下流側に向かって傾斜していればよい。なお、「剥離方向Ａの下流側に向かって傾斜している」とは、第２接合部３ｂの直線部分の端部から開封片２の側端までに伸びる直線から、当該直線部分の端部から当該開封片の上端までに伸びる直線までの間に含まれる斜線を意味する。 The hatched portion of the second joint portion 3b may completely reach the corner on the upper end side of the unsealing piece 2, or the hatched portion of the second joint portion 3b and the corner on the upper end side of the unsealing piece 2 may be reached. There may be a gap between them, and it is only necessary to incline from both ends of the straight portion of the second joint 3b toward the downstream side in the peeling direction A from the straight portion. Note that “inclined toward the downstream side in the peeling direction A” means that the end of the straight portion extends from a straight line extending from the end of the straight portion of the second joint 3b to the side end of the opening piece 2. Means a slanting line included between the opening and the straight line extending to the upper end of the opening piece.
　第２接合部３ｂの斜線部分は、それぞれ開封片２の上端側の角まで完全に到達していれば、開封片２のめくれに伴って第２接合部３ｂの直線部分の端部が意図せずに剥がれてピンホールを生じさせることを抑制することができる。 If the hatched portion of the second joining portion 3b has completely reached the corner on the upper end side of the opening piece 2, the end portion of the straight portion of the second joining portion 3b is intended as the opening piece 2 is turned over. It can suppress that it peels without generating a pinhole.
　ただし、第２接合部３ｂは、斜線部分を有していない形状、すなわち直線部分のみを有している形状であってもよい。また、第２接合部３ｂの中心部分は、包装体１と接合していなくてもよい。 However, the second joint 3b may have a shape that does not have a hatched portion, that is, a shape that has only a straight portion. Moreover, the center part of the 2nd junction part 3b does not need to join the package 1.
　第１接合部３ａによって面状に裂かれた包装フィルムを第２接合部３ｂに確実に到達させるために、第１接合部３ａと第２接合部３ｂとは対向していることが好ましい。第１接合部３ａの具体的な位置に限定はないが、第２接合部３ｂの中心部分に対向する位置に位置していることが望ましい。 It is preferable that the first joint portion 3a and the second joint portion 3b face each other in order to ensure that the packaging film that has been split into a planar shape by the first joint portion 3a reaches the second joint portion 3b. Although there is no limitation in the specific position of the 1st junction part 3a, it is desirable to be located in the position which opposes the center part of the 2nd junction part 3b.
　（第３接合部３ｃ）
　第３接合部３ｃは、開封片２を剥離方向Ａに剥がした際に、第２接合部３ｂによって面状に裂かれた包装フィルムを開封片付き包装体１０の後方に引き下げると、包装フィルムを包装体１の胴周方向Ｘに開裂させることの起点となる接合部である。具体的には、第３接合部３ｃは、第２接合部３ｂによって面状に裂かれた包装フィルムを開封片付き包装体１０の後方に引き下げた際に、包装フィルムを包装体１の胴周方向Ｘに開裂させることの起点となる切れ目を包装フィルムに与える接合部である。 (3rd junction part 3c)
When the 3rd junction part 3c pulls down the packaging film torn by the 2nd junction part 3b in the planar shape when peeling off the opening piece 2 in the peeling direction A, a packaging film will be packaged. It is a joint portion that is a starting point for cleaving in the body circumferential direction X of the body 1. Specifically, the third joint portion 3c is configured to remove the packaging film in the circumferential direction of the packaging body 1 when the packaging film that has been torn by the second joint portion 3b is pulled down to the rear of the packaging body 10 with the opening pieces. This is a joint that gives a cut to the packaging film as a starting point for cleaving to X.
　図１では、第３接合部３ｃは、開封片２の下端側の２つの角それぞれにおいて、開封片２の下辺から側辺まで延びる斜線形状を有している。ここで、第３接合部３ｃの胴周方向Ｘの幅は、第２接合部３ｂの胴周方向Ｘの幅よりも小さいことが好ましい。 In FIG. 1, the 3rd junction part 3c has the slanting line shape extended from the lower side to the side of the opening piece 2 in each of the two corners on the lower end side of the opening piece 2. Here, it is preferable that the width | variety of the trunk | drum circumferential direction X of the 3rd junction part 3c is smaller than the width | variety of the trunk | drum circumferential direction X of the 2nd junction part 3b.
　なお、第３接合部３ｃは、包装フィルムの開裂をより容易にするために形成されているものであり、接合部として第３接合部３ｃを形成せず第１接合部３ａおよび第２接合部３ｂのみを形成する構成であっても、包装フィルムを開裂させることはできる。 In addition, the 3rd junction part 3c is formed in order to make cleavage of a packaging film easier, and does not form the 3rd junction part 3c as a junction part, but the 1st junction part 3a and the 2nd junction part Even if it is the structure which forms only 3b, a packaging film can be cleaved.
　第３接合部３ｃには、開封片付き包装体１０をレトルト殺菌するレトルト工程、または開封片付き包装体１０を製造する包装工程等において開封片２がめくれてしまうことを抑制する機能を持たせることもできる。 The third joint 3c may have a function of preventing the opening piece 2 from being turned over in a retorting process for retorting the packaging body 10 with the opening piece or a packaging process for manufacturing the packaging body 10 with the opening piece. it can.
　第３接合部３ｃは、開封片２における剥離方向Ａの上流側の２つの角それぞれに形成されていてもよいし、第１接合部３ａの剥離方向Ａの上流側の端部と、第２接合部３ｂの剥離方向Ａの下流側の端部との間に形成されていてもよく、第２接合部３ｂの剥離方向Ａの下流側の端部よりも当該剥離方向Ａの上流側の位置に形成されていればよい。ただし、第３接合部３ｃが、開封片２における剥離方向Ａの上流側の２つの角それぞれに形成されていると、開封片２のめくれに伴って第２接合部３ｂの直線部分の端部が意図せずに剥がれてピンホールを生じさせることを抑制することができる。 The 3rd junction part 3c may be formed in each of two corners on the upstream side in the peeling direction A of the unsealing piece 2, or the upstream end part in the peeling direction A of the first joining part 3a, and the second It may be formed between the downstream end portion in the peeling direction A of the joint portion 3b, and the upstream position in the peeling direction A from the downstream end portion in the peeling direction A of the second joint portion 3b. What is necessary is just to be formed. However, when the 3rd junction part 3c is formed in each of two corners of the peeling direction A upstream in the unsealing piece 2, the edge part of the linear part of the 2nd junction part 3b with turning over of the unsealing piece 2 Can be prevented from unintentionally peeling off and causing pinholes.

　結紮部４は、内容物が充填された包装フィルムの上下端を収束させ、収束させた部分を合成樹脂テープで両側から挟み、収束させた部分を合成樹脂テープと共に加熱溶着し形成されている。合成樹脂テープとしては、包装フィルムと同様に塩化ビニリデン系樹脂を用いることが好ましく、さらに好ましくは塩化ビニリデン－塩化ビニル共重合体、塩化ビニリデン－メチルメタクリレート共重合体、または塩化ビニリデン－塩化ビニル－酢酸ビニル共重合体であり、特に好ましくは塩化ビニリデン－塩化ビニル共重合体である。なお、内容物を包装体１内に密封できれば結紮する方法は限定されず、包装フィルムの上下端をアルミワイヤー等で封止する方法、または包装フィルムの収束させた部分を直接溶着する方法等で結紮してもよい。 [Lying part]
The ligation part 4 is formed by converging the upper and lower ends of the packaging film filled with the contents, sandwiching the converged part with synthetic resin tape from both sides, and heating and welding the converged part together with the synthetic resin tape. As the synthetic resin tape, it is preferable to use a vinylidene chloride resin as in the case of the packaging film, more preferably a vinylidene chloride-vinyl chloride copolymer, a vinylidene chloride-methyl methacrylate copolymer, or a vinylidene chloride-vinyl chloride-acetic acid. Vinyl copolymers, particularly preferably vinylidene chloride-vinyl chloride copolymers. In addition, the method of ligating is not limited as long as the contents can be sealed in the package 1, such as a method of sealing the upper and lower ends of the packaging film with aluminum wires or the like, or a method of directly welding the converged portions of the packaging film, etc. You may ligate.
　［接合部の作用機序］
　開封片２における接合部の作用機序について、図２および図３を参照にして説明する。図２中の（ａ）～（ｄ）は、開封片付き包装体１０の開封片２を剥がすまでの各行程を示している。また、図３中の（ａ）および（ｂ）は、開封片付き包装体１０を開封するまでの各工程を示している。 [Mechanism of the joint]
The mechanism of action of the joint in the opening piece 2 will be described with reference to FIGS. 2 and 3. (A) to (d) in FIG. 2 show each process until the unsealed piece 2 of the package 10 with the unsealed piece is peeled off. Moreover, (a) and (b) in FIG. 3 has shown each process until it opens the package body 10 with an opening piece.
　まず、図２の（ａ）の状態で開封片付き包装体１０を保持し、開封片２の下端部分をつまむ。そして、開封片２をつまんだまま上方の結紮部４に向けて、すなわち剥離方向Ａに向けて剥がすと、第１接合部３ａでは開封片２と包装フィルムとが接合しているため、図２の（ｂ）に示すように、開封片２を剥がすことにより第１接合部３ａが包装フィルムに切れ目５ａを与える。その切れ目５ａが起点となり、包装フィルムは面状に裂かれる。このとき、第３接合部３ｃでも開封片２と包装フィルムとが接合しているため、開封片２を剥がすことにより第３接合部３ｃも包装フィルムに切れ目５ｃを与える。 First, the packaging body 10 with the opening piece is held in the state of FIG. 2A, and the lower end portion of the opening piece 2 is pinched. Then, when the opening piece 2 is pinched toward the upper ligation portion 4, that is, peeled in the peeling direction A, the opening piece 2 and the packaging film are joined at the first joining portion 3 a, and FIG. As shown in (b), the first joining portion 3a gives a cut 5a to the packaging film by peeling off the opening piece 2. The cut 5a is the starting point, and the packaging film is torn into a planar shape. At this time, since the unsealed piece 2 and the packaging film are also joined at the third joining portion 3c, the third joining portion 3c also gives the cut 5c to the packaging film by peeling off the unsealing piece 2.
　そのまま開封片２を上方の結紮部４に向けて剥がし、第１接合部３ａによって面状に裂かれた包装フィルムが第２接合部３ｂに到達すると、第２接合部３ｂでは開封片２と包装フィルムとが接合しているため、図２の（ｃ）に示すように、開封片２を剥がすことにより第２接合部３ｂが包装フィルムに切れ目５ｂを与える。その切れ目５ｂが起点となり、面状に裂かれる包装フィルムの胴周方向の幅が拡大する。 The unsealed piece 2 is peeled off toward the upper ligation portion 4 as it is, and when the packaging film that is torn into a plane by the first joint portion 3a reaches the second joint portion 3b, the unsealed piece 2 and the package are packaged at the second joint portion 3b. Since the film is bonded, as shown in FIG. 2C, the second bonding portion 3b gives the cut 5b to the packaging film by peeling off the opening piece 2. The cut 5b is the starting point, and the width of the packaging film that is torn into a plane is increased in the circumferential direction.
　本実施形態に係る開封片付き包装体１０では、開封片２が第１接合部３ａを有しているため、まず第１接合部３ａによって包装フィルムが面状に裂かれ、その状態で第２接合部３ｂにおいて包装フィルムの裂開が行われる。このように、開封片付き包装体１０では、開封片２を剥がす際、包装フィルムの裂開が段階的に行われるため、第２接合部３ｂにおいて包装フィルムを面状に裂くことができる。 In the package 10 with the unsealed piece according to the present embodiment, since the unsealed piece 2 has the first joining portion 3a, the packaging film is first split into a planar shape by the first joining portion 3a, and the second joining is performed in that state. In the part 3b, the packaging film is cleaved. Thus, in the packaging body 10 with an opening piece, since the tearing of a packaging film is performed in steps when peeling the opening piece 2, a packaging film can be teared in planar shape in the 2nd junction part 3b.
　第２接合部３ｂによって面状に裂かれた包装フィルムを上方の結紮部４に向けてさらに引っ張ることにより、図２の（ｄ）に示すように、面状に裂かれた包装フィルムを上方の結紮部４まで剥がすことができる。 By further pulling the packaging film that has been split into a planar shape by the second joint portion 3b toward the upper ligation portion 4, the packaging film that has been split into a planar shape is moved upward as shown in FIG. The ligation part 4 can be peeled off.
　そして、結紮部４まで裂かれた包装フィルムを開封片付き包装体１０の後方（矢印Ｂ方向）に引っ張り（図３の（ａ））、さらに開封片付き包装体１０の下方の結紮部４（矢印Ｃ方向）に向けて引き下げることによって、第２接合部３ｂによる切れ目５ｂが起点となって、包装フィルムが包装体１の胴周方向Ｘに開裂する（図３の（ｂ））。ここで、開封片２が第３接合部３ｃを有している場合は、第３接合部３ｃによる切れ目５ｃが包装フィルムを包装体１の胴周方向Ｘに開裂させる起点となるため、より容易に包装フィルムを包装体１の胴周方向Ｘに開裂させることができる。 Then, the packaging film that has been split to the ligation part 4 is pulled backward (in the direction of arrow B) of the package 10 with the unsealed piece ((a) in FIG. 3), and further the ligation part 4 (arrow C below the unwrapped package 10 with the arrow C). By pulling down in the direction (direction), the cut 5b by the second joint portion 3b is the starting point, and the packaging film is cleaved in the body circumferential direction X of the packaging body 1 ((b) of FIG. 3). Here, when the opening piece 2 has the 3rd junction part 3c, since the cut | interruption 5c by the 3rd junction part 3c becomes a starting point which tears a packaging film in the trunk | drum circumferential direction X of the package 1, it is easier. The packaging film can be cleaved in the circumferential direction X of the package 1.
　裂かれた包装フィルムをさらに開封片付き包装体１０の下方に引き下げていき、包装フィルムの開裂が包装フィルムを筒状に貼り合わせている部分に到達すると、貼り合わせている部分に沿って包装フィルムが開裂していく。この際、第２接合部３ｂによって、面状に裂かれる包装フィルムの胴周方向の幅が広がるため、面状に裂かれた包装フィルムを上方の結紮部４まで剥がした際に裂かれる包装フィルムの面積は大きい。そのため、結紮部４まで裂かれた包装フィルムを開封片付き包装体１０の後方に引き下げる際に容易に包装フィルムを包装体１の胴周方向Ｘに開裂させることができ、容易に開封片付き包装体１０を開封することができる。 The torn packaging film is further pulled down below the unwrapped package 10, and when the tear of the packaging film reaches the portion where the packaging film is bonded in a cylindrical shape, the packaging film is moved along the bonded portion. Cleavage. At this time, since the width of the packaging film that is torn into a planar shape is widened by the second bonding portion 3b, the packaging film that is torn when the packaging film that has been torn into a planar shape is peeled to the upper ligation portion 4 The area of is large. Therefore, the packaging film can be easily cleaved in the body circumferential direction X of the packaging body 1 when the packaging film that has been split to the ligation part 4 is pulled down to the rear of the packaging body 10 with the opening piece, and the packaging body 10 with the opening piece can be easily obtained. Can be opened.
　特に、開封片付き包装体１０では、剥離方向Ａを開封片付き包装体１０の長手方向Ｙとすることにより、図２および図３の工程を一連の工程として実行できるため、１つの工程で開封片付き包装体１０の開封に至ることができる。これに対して、従来の開封片付き包装体では、開封片が包装体の胴周方向に延びる直線状の溶着部で溶着されているのが一般的であるが、このような開封片付き包装体では、開封片をつまんで胴周方向にめくって剥がすことにより、包装フィルムの開裂のきっかけとなる線状の切れ目を包装フィルムにつける工程と、線状の切れ目の上方に位置する結紮部をつまんで開封片付き包装体の後方に引き下げて内容物を露出する工程との２つの行程を要する。 In particular, in the package 10 with an unsealed piece, by setting the peeling direction A as the longitudinal direction Y of the package 10 with an unsealed piece, the steps of FIG. 2 and FIG. 3 can be executed as a series of steps. The body 10 can be opened. On the other hand, in the conventional packaging body with an opening piece, it is common that the opening piece is welded by a linear welded portion extending in the body circumferential direction of the packaging body, but in such a packaging body with an opening piece, , By pinching the opening piece and peeling it off in the circumferential direction, pinching the linear cut that triggers the tearing of the packaging film on the packaging film, and pinching the ligature located above the linear cut Two steps are required: a step of pulling down the package with the opening piece and exposing the contents.
　このように、従来の開封片付き包装体では、開封片付き包装体を開封するまでに複数の工程を要するが、本実施形態に係る開封片付き包装体１０では、１つの工程で開封片付き包装体１０の開封にまで至らせることができるため、開封片付き包装体１０を開封するために手間がかからない。さらに、開封片２は開封片付き包装体１０を開封後も包装フィルム上に残留するため、剥がした開封片２を廃棄するための手間もかからない。 As described above, in the conventional package with an open piece, a plurality of steps are required until the package with an open piece is opened. However, in the package 10 with an open piece according to the present embodiment, the package 10 with an open piece in one step. Since it can reach to opening, it does not take time and effort to open the package 10 with the opening piece. Furthermore, since the unsealed piece 2 remains on the packaging film even after the unsealed packaging body 10 is unsealed, it does not require time and effort to discard the peeled unsealed piece 2.
　また、開封片２をめくる動作のみで開封片付き包装体１０の開封にまで至らせることができるので、開封片付き包装体１０の開封動作は消費者にとって分かりやすく、消費者は開封片付き包装体１０の開封方法を直感的に理解することができる。 Further, since the opening of the package 10 with the unsealed piece can be achieved only by turning the opening piece 2, the opening operation of the package 10 with the unsealed piece is easy for the consumer to understand. You can intuitively understand how to open.
　＜変形例＞
　第１接合部３ａは、包装フィルムを面状に裂くことが可能であれば特に大きさまたは形状は限定されない。そこで、図４に、第１接合部３ａの変形例を示す。 <Modification>
As long as the 1st junction part 3a can tear a packaging film into planar shape, a magnitude | size or a shape will not be specifically limited. FIG. 4 shows a modification of the first joint 3a.
　例えば、第１接合部３ａとして、円形状の第１接合部１３ａ（図４の（ａ））、ひし形状の第１接合部２３ａ（図４の（ｂ））、開封片２の胴周方向Ｘに延びる直線形状の第１接合部３３ａ（図４の（ｃ））、正方形状の第１接合部４３ａ（図４の（ｄ））、Ｖ字型の第１接合部５３ａ（図４の（ｅ））、円弧形状の第１接合部６３ａ（図４の（ｆ））、または三角形状の第１接合部７３ａ（図４の（ｇ））等、第１接合部３ａとは異なる形状の接合部も適用できる。 For example, as the first joint 3a, a circular first joint 13a (FIG. 4 (a)), a rhombus-shaped first joint 23a (FIG. 4 (b)), and the circumferential direction of the unsealed piece 2 A linear first joint 33a (FIG. 4C) extending in X, a square first joint 43a (FIG. 4D), a V-shaped first joint 53a (FIG. 4). (E)), an arc-shaped first joint 63a (FIG. 4 (f)), a triangular first joint 73a (FIG. 4 (g)), or a different shape from the first joint 3a. This joint can also be applied.
　なお、図４の（ａ）の第１接合部１３ａ、図４の（ｂ）の第１接合部２３ａ、図４の（ｄ）の第１接合部４３ａ、および図４の（ｇ）の第１接合部７３ａについては、各形状の内部領域も含めて包装体１に接合していてもよいし、外形に沿って包装体１に接合していてもよい。 4A, the first joint 23a in FIG. 4B, the first joint 43a in FIG. 4D, and the first joint 43a in FIG. 4G. About 1 junction part 73a, including the internal area | region of each shape may be joined to the package 1, and you may join to the package 1 along the external shape.
　また、第１接合部３ａの数に特に限定はなく、第１接合部３ａを２つ以上設けてもよい。２つ以上の第１接合部３ａを設ける場合、当該２つ以上の第１接合部３ａを胴周方向Ｘに並べて配置することが好ましい。これにより、各第１接合部３ａによって包装フィルムが面状に裂かれることになるため、面状に裂かれた包装フィルムが第２接合部３ｂに到達するまでに第１接合部３ａによって裂かれた包装フィルムの面積はより多くなる。それにより、第２接合部３ｂにおける包装フィルムの裂開がより容易になり、より確実に第２接合部３ｂにおいて包装フィルムを面状に裂くことができる。 Further, the number of the first joint portions 3a is not particularly limited, and two or more first joint portions 3a may be provided. When two or more first joint portions 3a are provided, the two or more first joint portions 3a are preferably arranged in the body circumferential direction X. As a result, the packaging film is torn into a planar shape by each first joining portion 3a, so that the packaging film that has been torn into a planar shape is torn by the first joining portion 3a before reaching the second joining portion 3b. The area of the wrapping film becomes larger. Thereby, the tearing of the packaging film at the second joint portion 3b becomes easier, and the packaging film can be more reliably split into a planar shape at the second joint portion 3b.
　第２接合部３ｂは、第１接合部３ａによって面状に裂かれた包装フィルムが第２接合部３ｂに到達した際に、面状に裂かれた包装フィルムの胴周方向の幅を広げることが可能であれば、特に大きさまたは形状は限定されない。そこで、図５に、第２接合部３ｂの変形例を示す。 The 2nd junction part 3b expands the width | variety of the trunk | drum circumferential direction of the packaging film teared planarly, when the packaging film teared planarly by the 1st junction part 3a reaches | attains the 2nd junction part 3b If possible, the size or shape is not particularly limited. FIG. 5 shows a modification of the second joint 3b.
　例えば、第２接合部３ｂとして、弧線形状の第２接合部１３ｂ（図５の（ａ））、ジグザグ線形状の第２接合部２３ｂ（図５の（ｂ））、波線形状の第２接合部３３ｂ（図５の（ｃ））、または胴周方向Ｘに延びる直線部分を有しており、当該直線部分には、その両端から開封片２の上端側に向かって延びる直線部分が形成されている第２接合部４３ｂ（図５の（ｄ））等、第２接合部３ｂとは異なる線形状の接合部も適用できる。第２接合部のさらなる別の形状として、胴周方向Ｘに延びる直線部分を有しており、当該直線部分には、その両端から開封片２の上端側の２つの角それぞれに向かって延びる２つの斜線部分が形成されている形状であって、胴周方向Ｘに延びる直線部分の長さが、第１接合部３ａの胴周方向Ｘにおける幅よりも短い形状である第２接合部５３ｂ（図５の（ｅ））、または第２接合部５３ｂにおける胴周方向Ｘに延びる直線部分を無くし、第２接合部５３ｂの斜線部分のみとした形状に相当する第２接合部６３ｂ（図５の（ｆ））も適用できる。 For example, as the second joint 3b, an arc-shaped second joint 13b (FIG. 5A), a zigzag-shaped second joint 23b (FIG. 5B), a wavy second joint Part 33b ((c) of FIG. 5) or a straight line portion extending in the trunk circumferential direction X, and a straight line portion extending from both ends toward the upper end side of the unsealing piece 2 is formed in the straight line portion. A linear joint different from the second joint 3b, such as the second joint 43b (FIG. 5D), can be applied. As still another shape of the second joint portion, it has a linear portion extending in the trunk circumferential direction X, and the linear portion extends from the both ends toward each of the two corners on the upper end side of the opening piece 2. The second joint portion 53b (a shape in which two oblique line portions are formed, and the length of the linear portion extending in the trunk circumferential direction X is shorter than the width of the first joint portion 3a in the trunk circumferential direction X. 5 (e)), or the second joint portion 63b corresponding to a shape in which the straight portion extending in the trunk circumferential direction X in the second joint portion 53b is eliminated and only the hatched portion of the second joint portion 53b is formed. (F)) is also applicable.
　また、第３接合部３ｃは、面状に裂かれた包装フィルムを開封片付き包装体１０の後方に引き下げた際に、包装フィルムを胴周方向Ｘに開裂することが可能であれば、特に大きさまたは形状は限定されない。そこで、図６に、第３接合部３ｃの変形例を示す。 Further, the third joint portion 3c is particularly large if the packaging film can be cleaved in the trunk circumferential direction X when the packaging film that has been split into a planar shape is pulled down to the rear of the package 10 with the unsealed piece. The size or shape is not limited. FIG. 6 shows a modified example of the third joint 3c.
　例えば、第３接合部３ｃとして、開封片２の下端側の２つの角それぞれから開封片２の内側に向かって延びる斜線形状の第３接合部１３ｃ（図６の（ａ））、頂点が開封片２の側辺と対向するように配置された三角形状の第３接合部２３ｃ（図６の（ｂ））、開封片２の胴周方向Ｘに延びる直線形状の第３接合部３３ｃ（図６の（ｃ））、円形状の第３接合部４３ｃ（図６の（ｄ））、または四角形状の第３接合部５３ｃ（図６（ｅ））等、第３接合部３ｃとは異なる形状の接合部も適用できる。 For example, as the third joint portion 3c, a hatched third joint portion 13c (FIG. 6 (a)) extending from the two corners on the lower end side of the unsealing piece 2 toward the inside of the unsealing piece 2, the apex being unsealed Triangular third joint portion 23c (FIG. 6B) arranged to face the side of piece 2, and linear third joint portion 33c (FIG. 6B) extending in the circumferential direction X of unsealed piece 2. 6 (c)), a circular third joint 43c (FIG. 6 (d)), or a quadrangular third joint 53 c (FIG. 6 (e)) or the like is different from the third joint 3 c. Shaped joints can also be applied.
　なお、図６の（ｂ）の第３接合部２３ｃ、図６の（ｄ）の第３接合部４３ｃ、および図６の（ｅ）の第３接合部５３ｃについては、各形状の内部領域も含めて包装体１に接合していてもよいし、外形に沿って包装体１に接合していてもよい。 In addition, about the 3rd junction part 23c of FIG. 6B, the 3rd junction part 43c of FIG. 6D, and the 3rd junction part 53c of FIG. It may be joined to the package 1 and may be joined to the package 1 along the outer shape.
　上述した種々の形状の接合部を組み合わせることにより、開封片付き包装体１０を装飾することもできる。例えば、接合部が開封片付き包装体１０の装飾をなしている例を図７に示す。図７は、本変形例に係る開封片付き包装体の一部分を示す正面図である。 The packaging body 10 with the opening pieces can be decorated by combining the joint portions having various shapes described above. For example, FIG. 7 shows an example in which the joint portion decorates the package 10 with the opening piece. FIG. 7 is a front view showing a part of the package with unsealed pieces according to the present modification.
　図７に示すように、図４の（ｇ）の第１接合部６３ａ、図５の（ｂ）の第２接合部２３ｂ、および図６の（ｄ）の第３接合部４３ｃを組み合わせ、開封片２に顔をデザインすることもできる。このように、種々の形状の接合部を組み合わせ、当該接合部によって開封片付き包装体１０を装飾することにより、開封片付き包装体１０のデザイン性を向上させることもできる。 As shown in FIG. 7, the first joint 63a in FIG. 4G, the second joint 23b in FIG. 5B, and the third joint 43c in FIG. 6D are combined and opened. The face can also be designed on the piece 2. Thus, the design property of the package 10 with an opening piece can also be improved by combining the junction part of various shapes and decorating the package body 10 with an opening piece by the said junction part.
　なお、以上では、開封片２を包装体１の長手方向Ｙに沿って剥がすことにより、開封片付き包装体１０を開封する構成を示したが、本発明は必ずしもこれに限定されるわけではない。例えば、開封片２を第２接合部３ｂが包装体１の長手方向Ｙに延びるように包装体１に取り付け、当該開封片２を包装体１の胴周方向Ｘに沿って剥がすことにより、開封片付き包装体１０を開封する構成も可能である。ただし、開封片２を包装体１の長手方向Ｙに沿って剥がすことにより、開封片付き包装体１０を開封する構成であれば、開封片付き包装体１０を１つの工程で開封することができるため、より好適である。 In addition, although the structure which opens the package 10 with an open piece by peeling the open piece 2 along the longitudinal direction Y of the package 1 was shown above, this invention is not necessarily limited to this. For example, the unsealing piece 2 is attached to the packaging body 1 so that the second joint portion 3b extends in the longitudinal direction Y of the packaging body 1, and the unsealing piece 2 is peeled along the trunk circumferential direction X of the packaging body 1 to open the opening piece 2. The structure which opens the package 10 with a piece is also possible. However, since it is the structure which opens the package 10 with an open piece by peeling the open piece 2 along the longitudinal direction Y of the package 1, since the package 10 with an open piece can be opened in one process, More preferred.
　以上のように、本発明の一態様に係る開封片付き包装体は、筒状に形成した包装フィルムの内部に内容物を充填し、両端を閉じて形成された包装体と、上記包装体と接合している接合部を有する開封片と、を備え、上記接合部は、上記開封片を所定方向に剥がすことによって、上記包装フィルムを面状に裂くことの起点となる第１接合部と、上記第１接合部よりも上記所定方向の下流側に位置し、上記開封片を上記所定方向に剥がした際に上記第１接合部によって面状に裂かれた上記包装フィルムが到達すると、面状に裂かれる上記包装フィルムの胴周方向の幅をさらに広げることの起点となる第２接合部と、を含む構成を有している。 As described above, the package with an unsealed piece according to one embodiment of the present invention includes a package formed by filling the contents of a packaging film formed in a cylindrical shape and closing both ends, and the package is joined to the package. An opening piece having a bonding portion, and the bonding portion peels off the opening piece in a predetermined direction, whereby the first bonding portion serving as a starting point for tearing the packaging film into a planar shape, When the packaging film, which is located downstream of the first joint portion in the predetermined direction and is torn by the first joint portion when the unsealing piece is peeled off in the predetermined direction, reaches the surface shape. And a second joint that is a starting point for further expanding the width of the packaging film in the circumferential direction of the packaging film to be torn.
　また、本発明に係る開封片付き包装体においては、上記所定方向は、上記開封片付き包装体の長手方向であり、上記第２接合部は、上記胴周方向に延びた線形状を有しており、上記第１接合部は、上記第２接合部よりも上記胴周方向の幅が小さい形状を有していることが好ましい。 In the package with an opening piece according to the present invention, the predetermined direction is a longitudinal direction of the package with the opening piece, and the second joining portion has a linear shape extending in the trunk circumferential direction. The first joint portion preferably has a shape having a width in the trunk circumferential direction smaller than that of the second joint portion.
　上記の構成によれば、第２接合部における包装フィルムの裂開時に、面状に裂かれる包装フィルムの胴周方向の幅をさらに広げることの起点となる切れ目を包装フィルムに与えることができる。 According to the above configuration, when the packaging film is torn at the second joint portion, it is possible to give the packaging film a break that becomes a starting point for further expanding the width of the packaging film in the circumferential direction.
　そして、開封片を開封片付き包装体の長手方向に沿って剥がすことにより、開封片付き包装体を１つの工程で開封することができるため、より好適である。 And, since the package with an open piece can be opened in one step by peeling the open piece along the longitudinal direction of the package with the open piece, it is more preferable.
　また、本発明に係る開封片付き包装体においては、上記接合部は、上記開封片を上記所定方向に剥がした際に上記第２接合部によって面状に裂かれた上記包装フィルムを上記開封片付き包装体の後方に引き下げると、上記包装フィルムを上記包装体の胴周方向に開裂させることの起点となる第３接合部をさらに含むことが好ましい。 Moreover, in the package with an opening piece according to the present invention, the bonding portion is formed by packaging the packaging film that has been split into a planar shape by the second bonding portion when the opening piece is peeled in the predetermined direction. It is preferable to further include a third joint portion that becomes a starting point for cleaving the packaging film in the body circumferential direction of the packaging body when pulled down to the rear of the body.
　上記の構成によれば、開封片を包装体より剥がした際に、第３接合部によって包装フィルムにつけられた切れ目が包装フィルムを胴周方向に開裂させる起点となるため、より容易に包装フィルムを包装体の胴周方向に開裂させることができる。結果、開封片付き包装体の開封がより容易になる。 According to the above configuration, when the unsealed piece is peeled off from the package, the break made in the packaging film by the third joint is a starting point for tearing the packaging film in the circumferential direction. It can be cleaved in the circumferential direction of the package. As a result, the opening of the package with the opening piece becomes easier.
　また、本発明に係る開封片付き包装体においては、上記第３接合部は、上記第２接合部よりも上記胴周方向の幅が小さい形状を有していることが好ましい。 Moreover, in the package with an opening piece according to the present invention, it is preferable that the third joint portion has a shape with a width in the trunk circumferential direction smaller than that of the second joint portion.
　上記の構成によれば、開封片を剥離方向に剥がした際に包装フィルムを包装体の胴周方向に開裂させる起点となる切れ目を包装フィルムに与えることができる。 According to the above configuration, when the unsealed piece is peeled in the peeling direction, a cut can be given to the packaging film as a starting point for tearing the packaging film in the body circumferential direction of the package.
　また、本発明に係る開封片付き包装体においては、上記開封片は、矩形であり、上記第２接合部は、上記線形状の両端から、当該線形状よりも上記所定方向の下流側に向かって傾斜している斜線部分を有していることが好ましい。 Moreover, in the packaging body with an opening piece which concerns on this invention, the said opening piece is a rectangle, and the said 2nd junction part is toward the downstream of the said predetermined direction rather than the said linear shape from the both ends of the said linear shape. It is preferable to have an inclined portion that is inclined.
　上記の構成によれば、斜線部分は、開封片付き包装体をレトルト殺菌するレトルト工程、または開封片付き包装体を製造する包装工程等において開封片がめくれてしまうことを抑制する機能を有している。 According to said structure, a shaded part has a function which suppresses that an open piece turns up in the retort process which retort-sterilizes the package body with an open piece, or the packaging process which manufactures the package body with an open piece. .
