Description

本発明は、嵌合具および嵌合具付き袋体に関する。   The present invention relates to a fitting tool and a bag body with a fitting tool.

食品、薬品および雑貨などの様々な分野において、袋体の開口を開閉自在に封じる嵌合具が取り付けられた嵌合具付き袋体が広く用いられている。嵌合具は、一対の帯状の基材に、雄側嵌合部および該雄側嵌合部に着脱自在に嵌合する雌側嵌合部が、前記基材の長手方向に沿ってそれぞれ設けられている。この嵌合具を袋体に取り付けて、雄側嵌合部と雌側嵌合部とを着脱させることにより、袋体の開口の開閉が繰り返し行える。   In various fields such as foods, medicines and miscellaneous goods, a bag body with a fitting tool to which a fitting tool for opening and closing the opening of the bag body is attached is widely used. The fitting tool is provided with a male-side fitting portion and a female-side fitting portion that is detachably fitted to the male-side fitting portion, respectively, along a longitudinal direction of the base material. It has been. By attaching the fitting tool to the bag body and detaching the male side fitting portion and the female side fitting portion, the opening and closing of the bag body can be repeatedly opened and closed.

一方、特に食品分野の嵌合具付き袋体としては、流通、販売時には完全に密封状態となっており、袋本体の端部に形成されたノッチ等から袋本体の一部を切除して開口を形成した後、形成した開口を嵌合具で自在に開閉するものが使用されている。この用途の嵌合具付き袋体に使用される嵌合具としては、最初の袋本体の開封時に、袋本体の一部を直線的に切断することを容易にする目的で、帯状の基材の内面（嵌合部を有する面）に、例えばＶ字状の溝からなる凹条の切断補助線を形成した嵌合具が知られている（例えば、特許文献１）。該嵌合具は、嵌合具の基材に形成された切断補助線に沿って、基材と共に袋本体の一部を切断して開口を形成できるようになっている。   On the other hand, especially as a bag body with a fitting tool in the food field, it is in a completely sealed state at the time of distribution and sale, and a part of the bag body is cut off from a notch formed at the end of the bag body and opened. After forming, the thing which opens and closes the formed opening freely with a fitting tool is used. The fitting used for the bag body with the fitting for this use is a belt-like base material for the purpose of easily cutting a part of the bag body linearly when the bag body is opened for the first time. There is known a fitting tool in which a concave cutting auxiliary line made of, for example, a V-shaped groove is formed on the inner surface (surface having a fitting portion) (for example, Patent Document 1). The fitting tool is configured so that an opening can be formed by cutting a part of the bag body together with the base material along a cutting auxiliary line formed on the base material of the fitting tool.

特開２０１０−０３５７１３号公報JP 2010-035713 A

しかし、特許文献１に記載のような、基材における嵌合部を有する面に凹条の切断補助線が形成された嵌合具は、該嵌合具を袋本体にヒートシールして取り付ける際に、ヒートシールの熱によって凹条近傍の樹脂が溶融し、凹条の断面形状が崩れることがある。凹条の断面形状が崩れると、切断補助線としての機能が低下し、その切断補助線に沿って袋体を切断することが困難になる。一方、凹条の切断補助線の断面形状が崩れないように、嵌合具を袋本体に取り付ける際のヒートシールを弱くすると、嵌合具が袋本体にしっかりと溶着せず、嵌合具が袋本体から剥離することがある。   However, as described in Patent Document 1, the fitting tool in which the concave cutting auxiliary line is formed on the surface having the fitting portion in the base material is attached when the fitting tool is heat-sealed to the bag body. In addition, the resin in the vicinity of the groove may be melted by heat of the heat seal, and the cross-sectional shape of the groove may be broken. If the cross-sectional shape of the concave stripe is broken, the function as a cutting auxiliary line is lowered, and it becomes difficult to cut the bag body along the cutting auxiliary line. On the other hand, if the heat seal at the time of attaching the fitting tool to the bag body is weakened so that the cross-sectional shape of the cutting aid line of the concave line does not collapse, the fitting tool does not weld firmly to the bag body, and the fitting tool May peel from the bag body.

本発明は、帯状の基材の対向面に凹条の切断補助線を有する嵌合具であって、袋本体に充分に溶着でき、かつ袋本体に取り付けた際、切断補助線に沿って基材と共に袋本体を容易に切断できる嵌合具、および該嵌合具を備えた易開封性の嵌合具付き袋体の提供を目的とする。   The present invention is a fitting having a concave cutting auxiliary line on the opposite surface of a belt-shaped base material, which can be sufficiently welded to the bag body and is attached to the bag main body along the cutting auxiliary line. It is an object of the present invention to provide a fitting that can easily cut a bag body together with a material, and a bag body with an easily openable fitting provided with the fitting.

基材１１は、公知の嵌合具における基材に通常使用される材質の基材が使用でき、積層フィルムからなる基材が好ましい。積層フィルムからなる基材１１としては、例えば、対向面１１ａ側から、耐熱層とヒートシール層が積層されたフィルムが挙げられる。
耐熱層の材質としては、ポリエチレン、ポリプロピレン、エチレン酢酸ビニル共重合体、アイオノマー等の熱可塑性樹脂が挙げられる。ヒートシール層としては、耐熱層より融点の低い熱可塑性樹脂等が挙げられる。 As the base material 11, a base material of a material normally used for a base material in a known fitting can be used, and a base material made of a laminated film is preferable. Examples of the substrate 11 made of a laminated film include a film in which a heat-resistant layer and a heat seal layer are laminated from the facing surface 11a side.

また、基材１１は、積層フィルムからなる基材には限定されず、単層フィルムからなる基材であってもよい。
基材１２は、基材１１と同じ材質の基材が使用でき、積層フィルムからなる基材が好ましい。
基材１１、１２の厚みは、０．１〜０．３ｍｍが好ましい。基材１１、１２の厚みとは、切断補助線、凸条および嵌合部が設けられていない部分の厚みである。 The base material 11 may consist of 1 type of resin, and may consist of the resin composition containing 2 or more types of resin. Moreover, well-known additives, such as a stabilizer, antioxidant, a lubricant, an antistatic agent, and a coloring agent, may be added as needed.
Moreover, the base material 11 is not limited to the base material which consists of laminated films, The base material which consists of a single layer film may be sufficient.
As the base material 12, a base material made of the same material as the base material 11 can be used, and a base material made of a laminated film is preferable.
As for the thickness of the base materials 11 and 12, 0.1-0.3 mm is preferable. The thickness of the base materials 11 and 12 is the thickness of the part in which the cutting auxiliary line, the protruding item | line, and the fitting part are not provided.

雄側嵌合部１３は、図１および図２（Ａ）に示すように、基材１１の対向面１１ａから突き出すように形成された幹部１３ａと、幹部１３ａよりも大きい断面略半円形状の頭部１３ｂを有している。また、雌側嵌合部１４は、基材１２の対向面１２ａから断面円弧状に突き出すアーム部１４ａ、１４ｂからなり、これらアーム部１４ａ、１４ｂにより凹部１４ｃが形成されている。雄側嵌合部１３と雌側嵌合部１４は、雄側嵌合部１３の頭部１３ｂを雌側嵌合部１４の凹部１４ｃに嵌め込むことで、着脱自在に嵌合できるようになっている。
雄側嵌合部１３と雌側嵌合部１４の形状は特に制限はなく、それらを着脱することで、袋体に形成した開口の開閉が繰り返し行えるものであれば、任意の形状を採用できる。
雄側嵌合部１３および雌側嵌合部１４の材質としては、基材１１、１２と同じ材質が使用できる。 As shown in FIGS. 1 and 2A, the male fitting portion 13 has a trunk portion 13a formed so as to protrude from the facing surface 11a of the base member 11, and a substantially semicircular cross section larger than the trunk portion 13a. It has a head 13b. Moreover, the female side fitting part 14 consists of the arm parts 14a and 14b which protrude in the cross-sectional arc shape from the opposing surface 12a of the base material 12, and the recessed part 14c is formed by these arm parts 14a and 14b. The male side fitting part 13 and the female side fitting part 14 can be detachably fitted by fitting the head part 13b of the male side fitting part 13 into the concave part 14c of the female side fitting part 14. ing.
The shapes of the male fitting portion 13 and the female fitting portion 14 are not particularly limited, and any shape can be adopted as long as the opening formed in the bag body can be repeatedly opened and closed by attaching and detaching them. .
As the material of the male side fitting part 13 and the female side fitting part 14, the same material as the base materials 11 and 12 can be used.

切断補助線１５は、基材１１を切断するのを補助する役割を果たす。つまり、基材１１は、凹条の切断補助線１５に沿って容易に切断できるようになっている。
切断補助線１５は、切断の容易性の点から、Ｖ字状の溝として形成され、凹条の断面形状が三角形状になっていることが好ましい。ただし、切断補助線１５の凹条の断面形状は、その切断補助線１５に沿って基材１１を切断できる形状であればよく、半円形状、矩形状であってもよい。 The cutting auxiliary line 15 serves to assist in cutting the base material 11. That is, the base material 11 can be easily cut along the concave cutting auxiliary line 15.
The cutting auxiliary line 15 is preferably formed as a V-shaped groove from the viewpoint of ease of cutting, and the cross-sectional shape of the groove is preferably triangular. However, the cross-sectional shape of the concave line of the cutting auxiliary line 15 may be a shape that can cut the base material 11 along the cutting auxiliary line 15, and may be a semicircular shape or a rectangular shape.

切断補助線１５の深さは、０．０２〜０．２８ｍｍが好ましい。切断補助線１５の深さが０．０２ｍｍ以上であれば、切断補助線１５に沿って基材１１を切断しやすい。切断補助線１５の深さが０．２８ｍｍ以下であれば、基材１１の成型時に基材１１が切断補助線１５に沿って切断してしまうことを抑制しやすい。
基材１１が前記耐熱層とヒートシール層が積層された積層フィルムからなる基材である場合、袋本体に取り付ける際のヒートシール時に切断補助線１５の断面形状が崩れ難い点から、切断補助線１５の深さは、その凹条の底が基材１１のヒートシール層まで達しない深さであることが好ましい。 The depth of the cutting auxiliary line 15 is preferably 0.02 to 0.28 mm. If the depth of the cutting auxiliary line 15 is 0.02 mm or more, it is easy to cut the base material 11 along the cutting auxiliary line 15. If the depth of the cutting auxiliary line 15 is 0.28 mm or less, it is easy to suppress the base material 11 from being cut along the cutting auxiliary line 15 when the base material 11 is molded.
When the base material 11 is a base material made of a laminated film in which the heat-resistant layer and the heat seal layer are laminated, the cutting auxiliary line is not easily collapsed at the time of heat sealing when attached to the bag body. The depth of 15 is preferably a depth at which the bottom of the recess does not reach the heat seal layer of the substrate 11.

切断補助線１７は、切断補助線１５と同様に、基材１２を切断するのを補助する役割を果たすものであり、凹条の断面形状および深さの好ましい態様は、切断補助線１５の好ましい態様と同じである。   Similarly to the cutting auxiliary line 15, the cutting auxiliary line 17 plays a role of assisting the cutting of the base material 12, and a preferable aspect of the cross-sectional shape and depth of the concave stripe is preferable for the cutting auxiliary line 15. Same as embodiment.

凸条１６ａ、１６ｂは、共に基材１１の雄側嵌合部１３よりも側端１１ｂ側に、切断補助線１５と並行して設けられている。凸条１６ａ、１６ｂと切断補助線１５が並行して設けられるとは、凸条１６ａ、１６ｂと切断補助線１５とが隣接して設けられていることを意味する。凸条１６ａは、基材１１の切断補助線１５よりも側端１１ｂ側に設けられ、凸条１６ｂは、切断補助線１５よりも雄側嵌合部１３側に設けられている。つまり、切断補助線１５が凸条１６ａと凸条１６ｂの間に位置している。
凸条１６ａと凸条１６ｂは、嵌合具１０を袋本体の内面にヒートシールにより取り付ける際、ヒートシールバーによって基材１１の切断補助線１５近傍に加わる圧力を低減する役割を果たす。これにより、ヒートシール時の熱によって切断補助線１５近傍の樹脂が溶融して、切断補助線１５の凹条の断面形状が崩れることを抑制できる。そのため、嵌合具１０を袋本体に取り付けた後、切断補助線１５に沿って基材１１と共に袋本体を容易に切断して袋本体を開封できる。 The ridges 16 a and 16 b are both provided on the side end 11 b side of the base material 11 on the side end 11 b side in parallel with the auxiliary cutting line 15. The fact that the ridges 16a and 16b and the cutting auxiliary line 15 are provided in parallel means that the ridges 16a and 16b and the cutting auxiliary line 15 are provided adjacent to each other. The ridge 16 a is provided on the side end 11 b side of the base material 11 with respect to the auxiliary cutting line 15, and the convex line 16 b is provided on the male side fitting portion 13 side of the auxiliary cutting line 15. That is, the cutting auxiliary line 15 is located between the ridge 16a and the ridge 16b.
The ridges 16a and ridges 16b serve to reduce the pressure applied to the vicinity of the cutting assisting line 15 of the base material 11 by the heat seal bar when the fitting 10 is attached to the inner surface of the bag body by heat sealing. Thereby, it can suppress that resin of the cutting auxiliary line 15 vicinity melt | dissolves with the heat | fever at the time of heat sealing, and the cross-sectional shape of the groove of the cutting auxiliary line 15 collapses. Therefore, after attaching the fitting tool 10 to the bag body, the bag body can be easily cut along with the base material 11 along the auxiliary cutting line 15 to open the bag body.

凸条１６ａ、１６ｂの断面形状は、この例では矩形状である。ただし、凸条１６ａ、１６ｂの断面形状は、嵌合具１０を袋本体の内面にヒートシールする際に基材１１の切断補助線１５近傍に加わる圧力を低減し、切断補助線１５の凹条の断面形状の変形を抑制できるものであればよい。例えば、凸条１６ａ、１６ｂの断面形状は、矩形状の他に、半円形状、台形状、三角形状などであってもよい。
凸条１６ａと凸条１６ｂの断面形状は、同じであってもよく、異なっていてもよい。 In this example, the cross-sectional shape of the ridges 16a and 16b is rectangular. However, the cross-sectional shape of the protrusions 16a and 16b reduces the pressure applied to the vicinity of the cutting auxiliary line 15 of the base material 11 when the fitting 10 is heat-sealed to the inner surface of the bag body, and the concave line of the cutting auxiliary line 15 is reduced. What is necessary is just to be able to suppress the deformation of the cross-sectional shape. For example, the cross-sectional shape of the ridges 16a and 16b may be a semicircular shape, a trapezoidal shape, a triangular shape, or the like in addition to the rectangular shape.
The cross-sectional shapes of the ridges 16a and the ridges 16b may be the same or different.

凸条１６ａの高さは、０．０２〜１．０ｍｍが好ましい。凸条１６ａの高さが０．０２ｍｍ以上であれば、嵌合具１０を袋体にヒートシールする際、切断補助線１５の凹条の断面形状が崩れることを抑制しやすい。凸条１６ａの高さが１．０ｍｍ以下であれば、凸条部分が大きすぎることに起因するヒートシール不良を抑制しやすい。
凸条１６ｂの高さは、凸条１６ａと同じ理由から、０．０２〜１．０ｍｍが好ましい。 As for the height of the protruding item | line 16a, 0.02-1.0 mm is preferable. If the height of the ridge 16a is 0.02 mm or more, it is easy to suppress the collapse of the cross-sectional shape of the ridge of the auxiliary cutting line 15 when the fitting 10 is heat-sealed to the bag. If the height of the ridges 16a is 1.0 mm or less, it is easy to suppress heat seal defects caused by the ridge portions being too large.
The height of the ridge 16b is preferably 0.02 to 1.0 mm for the same reason as the ridge 16a.

凸条１６ａと切断補助線１５との距離ｄ１（図２（Ｂ））は、０．２〜５．０ｍｍが好ましく、０．５〜３．０ｍｍがより好ましい。前記距離ｄ１が０．２ｍｍ以上であれば、嵌合具１０を袋体にヒートシールする際、凹状部に圧力が加わらず、断面形状の変形を抑制しやすい。前記距離ｄ１が５．０ｍｍ以下であれば、嵌合具１０を袋本体にヒートシールする際、凸条１６ａに圧力が集中して凹状部に圧力が加わらず、切断補助線１５の凹条の断面形状が崩れることを抑制しやすい。なお、凸条１６ａと切断補助線１５との距離ｄ１とは、凸条１６ａの切断補助線１５側の縁と、切断補助線１５の凸条１６ａ側の縁との距離である。
凸条１６ｂと切断補助線１５との距離ｄ２（図２（Ｂ））は、０．２〜５．０ｍｍが好ましく、０．５〜３．０ｍｍがより好ましい。前記距離ｄ２が０．２ｍｍ以上であれば、嵌合具１０を袋体にヒートシールする際、凹状部に圧力が加わらず、断面形状の変形を抑制しやすい。前記距離ｄ２が５．０ｍｍ以下であれば、嵌合具１０を袋体にヒートシールする際、凸条１６ｂに圧力が集中して凹状部に圧力が加わらず、切断補助線１５の凹条の断面形状が崩れることを抑制しやすい。なお、凸条１６ｂと切断補助線１５との距離ｄ２とは、凸条１６ｂの切断補助線１５側の縁と、切断補助線１５の凸条１６ｂ側の縁との距離である。 The distance d 1 (FIG. 2 (B)) between the ridge 16a and the auxiliary cutting line 15 is preferably 0.2 to 5.0 mm, and more preferably 0.5 to 3.0 mm. If the distance d 1 is 0.2mm or more, when heat sealing the fitment 10 to the bag, not applied pressure to the concave portion, it is easy to suppress deformation of the cross-sectional shape. If the distance d 1 is at 5.0mm or less, when the heat-sealing the fitment 10 on the bag body, not applied pressure to the concave portion concentrated pressure on the ridges 16a, concave cutting auxiliary line 15 It is easy to suppress the cross-sectional shape of. Note that the distance d 1 between the projections 16a and the auxiliary cutting line 15, and the edge of the auxiliary cutting line 15 side of the ridge 16a, the distance between the projections 16a side of the edge of the auxiliary cutting line 15.
The distance d 2 between the projections 16b and the auxiliary cutting line 15 (FIG. 2 (B)) is preferably from 0.2 to 5.0 mm, 0.5 to 3.0 mm is more preferable. If the distance d 2 is 0.2mm or more, when heat sealing the fitment 10 to the bag, not applied pressure to the concave portion, it is easy to suppress deformation of the cross-sectional shape. If the distance d 2 is at 5.0mm or less, when the heat-sealing the fitment 10 to the bag, not applied pressure to the concave portion concentrated pressure on the ridges 16b, concave cutting auxiliary line 15 It is easy to suppress the cross-sectional shape of. It should be noted that the distance d 2 between the projections 16b and the auxiliary cutting line 15, and the edge of the auxiliary cutting line 15 side ridges 16b, the distance between the projections 16b side of the edge of the auxiliary cutting line 15.

また、凸条１６ａ、１６ｂは、この例では実線状に連続的に設けられているが、嵌合具１０を袋本体にヒートシールする際に基材１１の切断補助線１５近傍に加わる圧力を低減し、切断補助線１５の凹条の断面形状の変形を抑制できる範囲内であれば、破線状に断続的に設けられていてもよい。
凸条１６ａ、１６ｂの材質は、基材１１と同じ材質を採用できる。基材１１が前記耐熱層とヒートシール層が積層された積層フィルムからなる基材である場合は、嵌合具１０を袋本体に取り付ける際のヒートシール時に熱によって変形し難く、切断補助線１５の断面形状を維持しやすい点から、凸条１６ａ、１６ｂの材質は耐熱層と同じ材質が好ましい。 In addition, the ridges 16a and 16b are continuously provided in a solid line shape in this example. However, when the fitting tool 10 is heat-sealed to the bag body, the pressure applied to the vicinity of the cutting auxiliary line 15 of the base material 11 is applied. As long as it is within a range that can be reduced and deformation of the cross-sectional shape of the recess of the auxiliary cutting line 15 can be suppressed, it may be provided intermittently in a broken line shape.
The same material as the base material 11 can be adopted as the material of the ridges 16a and 16b. When the base material 11 is a base material made of a laminated film in which the heat-resistant layer and the heat seal layer are laminated, it is difficult to be deformed by heat at the time of heat sealing when the fitting 10 is attached to the bag body, and the auxiliary cutting line 15 From the viewpoint of easily maintaining the cross-sectional shape, the material of the ridges 16a, 16b is preferably the same material as the heat-resistant layer.

凸条１８ａと凸条１８ｂは、凸条１６ａと凸条１６ｂと同様に、嵌合具１０を袋本体にヒートシールにより取り付ける際、ヒートシールバーによって基材１２の切断補助線１７近傍に加わる圧力を低減する役割を果たす。これにより、ヒートシール時の熱によって切断補助線１７近傍の樹脂が溶融して、切断補助線１７の凹条の断面形状が崩れることを抑制できる。そのため、嵌合具１０を袋体に取り付けた後、切断補助線１７に沿って基材１２および袋体を容易に切断できる。
凸条１８ａと凸条１８ｂの断面形状および高さの好ましい態様は、凸条１６ａと凸条１６ｂの断面形状および高さの好ましい態様と同じである。
また、凸条１８ａと切断補助線１７との距離の好ましい範囲は、凸条１６ａと切断補助線１５との距離ｄ１の好ましい範囲と同じである。凸条１８ｂと切断補助線１７との距離の好ましい範囲は、凸条１６ｂと切断補助線１５との距離ｄ２の好ましい範囲と同じである。 The protrusion 18a and the protrusion 18b are pressure applied to the vicinity of the cutting auxiliary line 17 of the base material 12 by the heat seal bar when the fitting 10 is attached to the bag body by heat sealing similarly to the protrusion 16a and protrusion 16b. It plays a role in reducing. Thereby, it can suppress that resin of the cutting auxiliary line 17 vicinity melt | dissolves with the heat | fever at the time of heat sealing, and the cross-sectional shape of the groove of the cutting auxiliary line 17 collapses. Therefore, the base material 12 and the bag body can be easily cut along the auxiliary cutting line 17 after the fitting tool 10 is attached to the bag body.
The preferable aspect of the cross-sectional shape and height of the protruding item | line 18a and the protruding item | line 18b is the same as the preferable aspect of the cross-sectional shape and height of the protruding item | line 16a and the protruding item | line 16b.
Further, a preferable range of the distance between the ridges 18 a and the auxiliary cutting lines 17 is the same as the preferable range of the distance d 1 between the ridges 16 a and the auxiliary cutting lines 15. A preferred range of the distance between the projections 18b and the auxiliary cutting line 17 are the same as the preferred range of the distance d 2 between the projections 16b and the auxiliary cutting line 15.

（嵌合具付き袋体）
次に、前述した嵌合具１０を備えた嵌合具付き袋体１（以下、単に「袋体１」という。）について説明する。
袋体１は、図３に示すように、内容物を収容する密封された状態の袋本体２０と、袋本体２０内の上部に横方向に沿って設けられた嵌合具１０とを有している。 (Bag with fitting)
Next, the bag body 1 with a fitting tool (hereinafter simply referred to as “bag body 1”) including the fitting tool 10 described above will be described.
As shown in FIG. 3, the bag body 1 includes a bag body 20 in a sealed state that accommodates contents, and a fitting 10 that is provided in the upper portion of the bag body 20 along the lateral direction. ing.

袋本体２０は、２枚のフィルム材２１、２２が重ね合わされ、それらの周縁部２３が全てヒートシールされることで形成されており、密封された状態になっている。
袋本体２０の形状は、本実施形態では矩形である。ただし、袋本体２０の形状は矩形には限定されない。また、袋本体２０の大きさも特に限定されず、袋本体２０に収容する内容物によって適宜選定すればよい。 The bag body 20 is formed by superimposing two film materials 21 and 22 and heat-sealing all the peripheral edge portions 23 thereof, and is in a sealed state.
The shape of the bag body 20 is rectangular in this embodiment. However, the shape of the bag body 20 is not limited to a rectangle. Further, the size of the bag body 20 is not particularly limited, and may be appropriately selected depending on the contents accommodated in the bag body 20.

袋本体２０を形成するフィルム材２１、２２は、ヒートシールにより嵌合具１０を溶着できるものであればよく、内面側からシーラント層と基材層を少なくとも有する積層フィルムが好ましい。
基材層としては、二軸延伸ナイロン、二軸延伸ポリプロピレンなどが挙げられる。
シーラント層としては、直鎖状低密度ポリエチレン、無延伸ポリプロピレン、エチレン−酢酸ビニル共重合体、アイオノマーなどが挙げられる。
また、前記積層フィルムには、バリア層などの機能層を設けてもよい。
また、フィルム材２１、２２は、シーラント層のみからなる単層フィルムであってもよい。 The film materials 21 and 22 forming the bag body 20 may be any film material that can weld the fitting 10 by heat sealing, and a laminated film having at least a sealant layer and a base material layer from the inner surface side is preferable.
Examples of the base material layer include biaxially stretched nylon and biaxially stretched polypropylene.
Examples of the sealant layer include linear low density polyethylene, unstretched polypropylene, ethylene-vinyl acetate copolymer, and ionomer.
The laminated film may be provided with a functional layer such as a barrier layer.
Further, the film materials 21 and 22 may be single-layer films composed only of a sealant layer.

嵌合具１０は、基材１１の側端１１ｂ側および基材１２の側端１２ｂ側が袋体１の上部側に向くように、袋本体２０に取り付けられている。また、嵌合具１０は、図４に示すように、嵌合具１０の基材１１が袋本体２０のフィルム材２１に溶着され、嵌合具１０の基材１２が袋本体２０のフィルム材２２に溶着されて取り付けられている。
また、袋本体２０における嵌合具１０の切断補助線１５、１７の末端部分に対応する位置には、図３に示すように、ノッチ２４が形成されている。ノッチ２４の形状は、この例では三角形状であるが、特に限定されず、半円形状、直線状などであってもよい。 The fitting 10 is attached to the bag body 20 so that the side end 11b side of the base material 11 and the side end 12b side of the base material 12 face the upper side of the bag body 1. 4, the base material 11 of the fitting tool 10 is welded to the film material 21 of the bag body 20, and the base material 12 of the fitting tool 10 is the film material of the bag body 20. 22 is attached by welding.
Further, as shown in FIG. 3, a notch 24 is formed at a position corresponding to the end portions of the auxiliary cutting lines 15 and 17 of the fitting 10 in the bag body 20. The shape of the notch 24 is triangular in this example, but is not particularly limited, and may be semicircular or linear.

袋体１は、ノッチ２４から、切断補助線１５および切断補助線１７に沿って、嵌合具１０の基材１１、１２および袋本体２０のフィルム材２１、２２を切断して、上部を開封できるようになっている。また、開封後の袋体１は、嵌合具１０の雄側嵌合部１３と雌側嵌合部１４を着脱することで、形成した開口を自在に開閉できる。   The bag body 1 cuts the base materials 11 and 12 of the fitting 10 and the film materials 21 and 22 of the bag main body 20 from the notch 24 along the cutting auxiliary line 15 and the cutting auxiliary line 17 and opens the upper part. It can be done. Moreover, the bag body 1 after opening can freely open and close the formed opening by attaching and detaching the male side fitting part 13 and the female side fitting part 14 of the fitting 10.

嵌合具１０の袋本体２０へのヒートシールは、例えば、図５に示すように、フィルム材２１とフィルム材２２の間に嵌合具１０を配置し、基材１１と基材１２の間に冷却バー１０１、１０２を挿入した状態で、フィルム材２１とフィルム材２２の外側からヒートシールバー１０３、１０４で挟み込んで加熱することにより行われる。このとき、基材１１の切断補助線１５近傍は、凸条１６ａと凸条１６ｂの部分が冷却バー１０１とヒートシールバー１０３に挟まれて押圧されるため、冷却バー１０１が接触せず加わる圧力が小さい。そのため、ヒートシールバー１０３から基材１１の切断補助線１５近傍に加わる熱量が少なく、樹脂が溶融して切断補助線１５の凹条の断面形状が崩れることを抑制できる。同様に、基材１２の切断補助線１７近傍は、凸条１８ａと凸条１８ｂの部分が冷却バー１０１とヒートシールバー１０４に挟まれて押圧されるため、冷却バー１０１が接触せず加わる圧力が小さい。そのため、ヒートシールバー１０４から基材１２の切断補助線１７近傍に加わる熱量が少なく、樹脂が溶融して切断補助線１７の凹条の断面形状が崩れることを抑制できる。よって、形成される袋体１は、袋本体２０に取り付けた後も嵌合具１０の切断補助線１５、１７の断面形状が維持されるため、切断補助線１５、１７に沿って基材１１、１２と共にフィルム材２１、２２を切断して容易に開封できる。
一方、基材１１の切断補助線１５近傍、および基材１２の切断補助線１７近傍は、他の部分に比べてヒートシールが弱くなり、場合によってはほとんどヒートシールされないこともある。しかし、基材１１の切断補助線１５の両側の凸条１６ａ、１６ｂの部分がしっかりとフィルム材２１に溶着される。同様に、基材１１の切断補助線１５近傍はほとんどヒートシールされないこともあるが、切断補助線１７の両側の凸条１８ａ、１８ｂの部分がしっかりとフィルム材２２に溶着される。そのため、嵌合具１０が袋本体２０から剥離することはなく、使用上問題は生じない。 For example, as shown in FIG. 5, the heat sealing of the fitting tool 10 to the bag body 20 is performed by placing the fitting tool 10 between the film material 21 and the film material 22 and between the base material 11 and the base material 12. In the state where the cooling bars 101 and 102 are inserted, the heat sealing bars 103 and 104 are sandwiched from the outside of the film material 21 and the film material 22 and heated. At this time, in the vicinity of the cutting assisting line 15 of the base material 11, the portions of the ridges 16 a and the ridges 16 b are pressed between the cooling bar 101 and the heat seal bar 103. Is small. Therefore, the amount of heat applied from the heat seal bar 103 to the vicinity of the cutting auxiliary line 15 of the base material 11 is small, and it is possible to suppress the melting of the resin and the cross-sectional shape of the concave stripe of the cutting auxiliary line 15 being collapsed. Similarly, in the vicinity of the cutting assistance line 17 of the base material 12, the portions of the ridges 18 a and the ridges 18 b are pressed between the cooling bar 101 and the heat seal bar 104. Is small. Therefore, the amount of heat applied from the heat seal bar 104 to the vicinity of the cutting auxiliary line 17 of the base material 12 is small, and it is possible to suppress the melting of the resin and the collapse of the cross-sectional shape of the concave line of the cutting auxiliary line 17. Therefore, since the cross-sectional shape of the cutting auxiliary lines 15 and 17 of the fitting 10 is maintained after the bag body 1 to be formed is attached to the bag main body 20, the base material 11 extends along the cutting auxiliary lines 15 and 17. , 12 and the film materials 21 and 22 can be cut and easily opened.
On the other hand, in the vicinity of the cutting assisting line 15 of the base material 11 and in the vicinity of the cutting auxiliary line 17 of the base material 12, heat sealing is weaker than other parts, and in some cases, heat sealing is hardly performed. However, the portions of the ridges 16 a and 16 b on both sides of the auxiliary cutting line 15 of the substrate 11 are firmly welded to the film material 21. Similarly, the vicinity of the cutting auxiliary line 15 of the base material 11 may be hardly heat-sealed, but the portions of the ridges 18 a and 18 b on both sides of the cutting auxiliary line 17 are firmly welded to the film material 22. Therefore, the fitting tool 10 is not peeled off from the bag main body 20, and there is no problem in use.

＜第２実施形態＞
（嵌合具）
本発明の嵌合具の他の実施形態である嵌合具１０Ａについて、図６に基づいて説明する。嵌合具１０Ａにおいて、前述した嵌合具１０と同じ部分は、同じ符号を付して説明を省略する。
嵌合具１０Ａは、図６に示すように、一対の帯状の基材１１、１２を有している。基材１１の対向面１１ａには、基材１１の長手方向に沿って雄側嵌合部１３が設けられ、雄側嵌合部１３の側端１１ｂ側に、切断補助線１５と凸条１６ａが順に、基材１１の長手方向に沿って並行して設けられている。基材１２の対向面１２ａには、それぞれ基材１２の長手方向に沿って雌側嵌合部１４が設けられ、雌側嵌合部１４の側端１２ｂ側に、切断補助線１７と凸条１８ａとが順に、それぞれ基材１２の長手方向に沿って並行して設けられている。
すなわち、嵌合具１０Ａは、凸条１６ｂと凸条１８ｂとが設けられていない以外は、嵌合具１０と同じである。 Second Embodiment
(Fitting tool)
10A of fitting tools which are other embodiment of the fitting tool of this invention are demonstrated based on FIG. In 10A of fitting tools, the same part as the fitting tool 10 mentioned above attaches | subjects the same code | symbol, and abbreviate | omits description.
As shown in FIG. 6, the fitting 10 </ b> A has a pair of belt-like base materials 11 and 12. The opposing surface 11a of the base material 11 is provided with a male side fitting portion 13 along the longitudinal direction of the base material 11, and on the side end 11b side of the male side fitting portion 13, a cutting auxiliary line 15 and a ridge 16a. Are provided in parallel along the longitudinal direction of the substrate 11. A female side fitting portion 14 is provided on each of the opposing surfaces 12a of the base material 12 along the longitudinal direction of the base material 12, and the cutting auxiliary line 17 and the ridges are provided on the side end 12b side of the female side fitting portion 14. 18a are sequentially provided in parallel along the longitudinal direction of the substrate 12 respectively.
That is, the fitting tool 10A is the same as the fitting tool 10 except that the protrusion 16b and the protrusion 18b are not provided.

（嵌合具付き袋体）
嵌合具１０Ａを備えた嵌合具付き袋体は、内容物を収容する密封された状態の袋本体に、嵌合具１０と同様に、基材１１の側端１１ｂ側、および基材１２の側端１２ｂ側が該袋本体の上部側（開口を形成する側）に向くように取り付けることで得られる。嵌合具１０Ａを使用する場合も嵌合具１０の場合と同様に、袋本体へのヒートシールの際、凸条１６ａの部分が冷却バーとヒートシールバーに挟まれて押圧されることで、基材１１の切断補助線１５近傍は冷却バーが接触せず、ヒートシールバーから伝わる熱量が少ない。そのため、切断補助線１５近傍の樹脂が溶融して切断補助線１５の凹条の断面形状が崩れることが抑制される。また、凸条１８ａの部分が冷却バーとヒートシールバーに挟まれて押圧されることで、基材１２の切断補助線１７近傍にも冷却バー１０１が接触せず、切断補助線１７近傍の樹脂が溶融して切断補助線１７の凹条の断面形状が崩れることが抑制される。よって、嵌合具１０Ａを取り付けた袋体も、切断補助線１５、１７の断面形状が維持され、それら切断補助線１５、１７に沿って容易に開封できる。 (Bag with fitting)
The bag body with a fitting tool provided with the fitting tool 10A is provided on the side of the side end 11b of the base material 11 and the base material 12 in the same manner as the fitting tool 10 in the sealed bag body that accommodates the contents. The side end 12b side of the bag is attached so as to face the upper side of the bag body (side on which the opening is formed). Even when using the fitting tool 10A, as in the case of the fitting tool 10, when the heat sealing to the bag body, the portion of the ridge 16a is sandwiched and pressed between the cooling bar and the heat sealing bar, The cooling bar does not contact the vicinity of the cutting auxiliary line 15 of the base material 11, and the amount of heat transmitted from the heat seal bar is small. Therefore, it is possible to prevent the resin in the vicinity of the cutting auxiliary line 15 from melting and the cross-sectional shape of the concave line of the cutting auxiliary line 15 from collapsing. Further, the protrusion 18a is sandwiched between the cooling bar and the heat seal bar and pressed, so that the cooling bar 101 does not come into contact with the cutting auxiliary line 17 in the base 12 and the resin in the vicinity of the cutting auxiliary line 17 is present. It is suppressed that melt | dissolves and the cross-sectional shape of the groove of the auxiliary cutting line 17 collapses. Therefore, the bag body to which the fitting tool 10 </ b> A is attached also maintains the cross-sectional shape of the cutting auxiliary lines 15 and 17 and can be easily opened along the cutting auxiliary lines 15 and 17.

以上説明したように、本発明の嵌合具は、袋本体にヒートシールする際に凹条の切断補助線の断面形状が崩れずに維持される。そのため、本発明の嵌合具を有する嵌合具付き袋体は、嵌合具の切断補助線に沿って容易に開封できる。また、基材が積層フィルムの場合、基材の対向面に形成する凸条を耐熱性の樹脂にしやすいため、該凸条が熱により変形し難くなるので、結果として切断補助線の凹条の変形を抑制する効果が高くなる。   As described above, the fitting tool of the present invention maintains the cross-sectional shape of the concave cutting assisting line when it is heat sealed to the bag body. Therefore, the bag body with a fitting tool which has a fitting tool of the present invention can be easily opened along the cutting auxiliary line of the fitting tool. In addition, when the base material is a laminated film, the protrusions formed on the opposing surface of the base material are easily made of a heat-resistant resin, so that the protrusions are not easily deformed by heat. The effect of suppressing deformation is increased.

なお、本発明の嵌合具は、前述した嵌合具１０、１０Ａには、限定されない。例えば、凸条が、切断補助線の嵌合部側のみに設けられている嵌合具であってもよい。すなわち、基材１１の切断補助線１５の雄側嵌合部１３側に凸条１６ｂ、基材１２の切断補助線１７の雌側嵌合部１４側に凸条１８ｂが設けられ、凸条１６ａと凸条１８ａが設けられていない嵌合具であってもよい。ただし、凸条が切断補助線の一方の側のみに設けられる場合は、嵌合具１０Ａのように、切断補助線の側端側、つまり嵌合部から遠い側に凸条が設けられることが好ましい。これは、嵌合具を袋本体にヒートシールする際に使用される冷却バーが、通常、様々な形状の嵌合具に対応させる目的で、図３に示すように、先細りの形状となっているためである。このような形状の冷却バーを使用する場合、切断補助線の側端側、つまり嵌合部から遠い側に設けられた凸条の方が、ヒートシールバーと冷却バーに早く接触するので、切断補助線の断面形状が崩れることを抑制する効果が高い。
また、本発明の嵌合具は、一方の基材のみに、切断補助線と凸条が設けられた嵌合具であってもよい。 In addition, the fitting tool of this invention is not limited to the fitting tools 10 and 10A mentioned above. For example, the protrusion may be a fitting provided only on the fitting portion side of the cutting auxiliary line. That is, the protrusion 16b is provided on the male side fitting portion 13 side of the cutting assisting line 15 of the base material 11, and the protrusion 18b is provided on the female side fitting portion 14 side of the cutting auxiliary line 17 of the base material 12, and the protrusion 16a. The fitting may not be provided with the ridges 18a. However, when the protruding line is provided only on one side of the cutting auxiliary line, the protruding line may be provided on the side end side of the cutting auxiliary line, that is, on the side far from the fitting part, like the fitting 10A. preferable. This is because the cooling bar used when heat-sealing the fitting to the bag body usually has a tapered shape as shown in FIG. 3 for the purpose of accommodating various shapes of fitting. Because it is. When using a cooling bar with such a shape, the protruding strip provided on the side end side of the auxiliary cutting line, that is, on the side far from the fitting portion, comes into contact with the heat seal bar and the cooling bar earlier. The effect which suppresses that the cross-sectional shape of an auxiliary line collapses is high.
In addition, the fitting tool of the present invention may be a fitting tool in which cutting auxiliary lines and ridges are provided on only one base material.
