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.

袋体本体の開口部近傍の内面にテープ状の嵌合具（ジッパーテープ）を取り付けることにより、開閉自在とされた嵌合具付き袋体（チャック袋）が知られている（例えば、特許文献１）。該嵌合具は、突条の嵌合雄部が形成された第１のテープ体と、凹条の嵌合雌部が形成された第２のテープ体とを備え、嵌合雄部と嵌合雌部とが着脱可能に嵌合するものである。   A bag body (chuck bag) with a fitting tool that can be opened and closed by attaching a tape-shaped fitting tool (zipper tape) to the inner surface of the bag body near the opening is known (for example, Patent Documents). 1). The fitting includes a first tape body in which a male fitting portion of a protrusion is formed, and a second tape body in which a female fitting portion of a concave stripe is formed, and the fitting male portion and the fitting are fitted. The mating female part is detachably fitted.

この嵌合具付き袋体は、嵌合具よりも開口部側から容易に開封できるように、嵌合強度が低く抑えられている。そのため、嵌合具よりも内側の袋体本体の内圧が高まった場合、該内圧によって嵌合雄部が嵌合雌部から脱離し、嵌合具付き袋体が開封されてしまうという問題がある。   This bag body with a fitting tool has a low fitting strength so that it can be opened more easily than the fitting tool from the opening side. Therefore, when the internal pressure of the bag body inside the fitting tool is increased, the fitting male part is detached from the fitting female part due to the internal pressure, and the bag body with the fitting tool is unsealed. .

この問題を解決する嵌合具付き袋体としては、嵌合雄部およびこの両側に平行に設けられた２条の突起部が形成された第１のテープ体と、嵌合雌部およびこの両側に平行に設けられた２条の突起部が形成された第２のテープ体とを備えた嵌合具付き袋体が提案されている（例えば、特許文献２）。   As a bag body with a fitting tool for solving this problem, a first tape body in which a fitting male part and two protrusions provided in parallel on both sides are formed, a fitting female part and both sides thereof are provided. There has been proposed a bag body with a fitting tool provided with a second tape body on which two protrusions provided in parallel to each other are formed (for example, Patent Document 2).

この嵌合具付き袋体においては、袋体本体の内圧が高まり、嵌合雄部および嵌合雌部よりも袋体本体内側の第１のテープ体と第２のテープ体との間隔が拡がった際に、嵌合雄部よりも袋体本体開口部側の第１のテープ体の突起部と、これに対応する第２のテープ体の突起部とが衝突することにより、嵌合雄部の嵌合雌部からの脱離が抑制される。   In this bag body with a fitting tool, the internal pressure of the bag body increases, and the interval between the first tape body and the second tape body inside the bag body is larger than the fitting male part and the fitting female part. When the protruding portion of the first tape body on the bag body main body opening side of the fitting male portion collides with the protruding portion of the second tape body corresponding thereto, the fitting male portion Detachment from the fitting female portion is suppressed.

しかしながら、この嵌合具付き袋体は、突起部が嵌合雄部および嵌合雌部の両側に２条ずつ設けられているため、嵌合具よりも開口部側から開封しようとしても、袋体本体内側側の第１のテープ体の突起部と、これに対応する第２のテープ体の突起部とが衝突してしまう。そのため、嵌合具よりも開口部側から開封しにくいという問題がある。
特開２００５−１３１１８５号公報 米国特許第５３６８３９４号明細書 However, since the protrusion is provided with two protrusions on both sides of the fitting male part and the fitting female part, the bag body with the fitting tool can be opened from the opening side rather than the fitting tool. The protrusion part of the 1st tape body inside a body main body and the protrusion part of the 2nd tape body corresponding to this will collide. Therefore, there exists a problem that it is hard to open from an opening side rather than a fitting tool.

図１は、本発明の嵌合具の一例を示す断面図である。嵌合具１０は、突条の嵌合雄部２０および該嵌合雄部２０の一方の側に平行に設けられた突条の突起部３０を有する第１のテープ体４０と、嵌合雄部２０に着脱可能に嵌合する、凹条の嵌合雌部５０を有する第２のテープ体６０とを具備するものである。   FIG. 1 is a cross-sectional view showing an example of the fitting of the present invention. The fitting 10 includes a first tape body 40 having a fitting male portion 20 of a protrusion and a protruding portion 30 of a protrusion provided in parallel on one side of the fitting male portion 20, and a fitting male. And a second tape body 60 having a concave fitting female portion 50 detachably fitted to the portion 20.

嵌合雄部２０は、第１のテープ体本体４１から略直角に立ち上がった、第１のテープ体本体４１の長手方向に延びる幹部２１と、該幹部２１の先端に形成された断面半円形の頭部２２とから構成される。
頭部２２には、側方に突出した第１の雄係止爪部２３および第２の雄係止爪部２４が形成されている。 The fitting male part 20 rises from the first tape body main body 41 at a substantially right angle and extends in the longitudinal direction of the first tape body main body 41 and has a semicircular cross section formed at the tip of the trunk part 21. And a head 22.
The head portion 22 is formed with a first male locking claw portion 23 and a second male locking claw portion 24 that protrude laterally.

嵌合雌部５０は、第２のテープ体本体６１から断面略円弧状に立ち上がった、第２のテープ体本体６１の長手方向に延びる第１のアーム部５１および第２のアーム部５２から構成される。
第１のアーム部５１の先端には、嵌合雄部２０側に突出した第１の雌係止爪部５３が形成されている。また、第２のアーム部５２の先端には、嵌合雄部２０側に突出した第２の雌係止爪部５４が形成されている。 The fitting female part 50 is composed of a first arm part 51 and a second arm part 52 which rise from the second tape body main body 61 in a substantially arc shape and extend in the longitudinal direction of the second tape body main body 61. Is done.
A first female locking claw portion 53 that protrudes toward the fitting male portion 20 is formed at the tip of the first arm portion 51. In addition, a second female locking claw portion 54 protruding toward the fitting male portion 20 is formed at the tip of the second arm portion 52.

第１のアーム部５１と第２のアーム部５２とから形成される断面半円形の凹部５５内には、嵌合雄部２０の頭部２２が嵌合する。雌係止爪部５３と雌係止爪部５４との間には、嵌合雄部２０の幹部２１と同程度の幅の隙間が形成されている。   The head 22 of the fitting male part 20 is fitted in a concave part 55 having a semicircular cross section formed by the first arm part 51 and the second arm part 52. Between the female locking claw portion 53 and the female locking claw portion 54, a gap having the same width as the trunk portion 21 of the fitting male portion 20 is formed.

第１の雌係止爪部５３が当接する第１の雄係止爪部２３の面は、第２のテープ体６０側に傾斜している。これにより、第１の雄係止爪部２３と第１の雌係止爪部５３との引っ掛かりは弱くなり、第１の雌係止爪部５３は、第１の雄係止爪部２３から外れやすくなっている。   The surface of the first male locking claw portion 23 with which the first female locking claw portion 53 abuts is inclined toward the second tape body 60 side. As a result, the catch between the first male locking claw portion 23 and the first female locking claw portion 53 is weakened, and the first female locking claw portion 53 is separated from the first male locking claw portion 23. It is easy to come off.

また、第２の雌係止爪部５４が当接する第２の雄係止爪部２４の面は、第１のテープ体本体４１側に傾斜している。これにより、第２の雄係止爪部２４と第２の雌係止爪部５４との引っ掛かりが維持され、第２の雌係止爪部５４は、第２の雄係止爪部２４から外れにくくなっている。   Further, the surface of the second male locking claw portion 24 with which the second female locking claw portion 54 abuts is inclined toward the first tape body main body 41 side. Thereby, the catch of the 2nd male locking claw part 24 and the 2nd female locking claw part 54 is maintained, and the 2nd female locking claw part 54 is from the 2nd male locking claw part 24. It is hard to come off.

突起部３０は、突起部３０がない側の第１のテープ体４０と第２のテープ体６０との間隔が拡がるときに、嵌合雌部５０の側面に当接するように設けられていればよい。よって、突起部３０がない側の第１のテープ体４０と第２のテープ体６０との間隔が拡がる前には、図１のように、突起部３０は嵌合雌部５０の側面（アーム部５１の側面）に当接していてもよく、図２に示すように、突起部３０は嵌合雌部５０（アーム部５１）から離間していてもよい。
また、突起部３０の高さは、突起部３０がない側の第１のテープ体４０と第２のテープ体６０との間隔が拡がるときに嵌合雌部５０の側面に当接するように、適宜設定される。 If the protrusion 30 is provided so as to contact the side surface of the fitting female part 50 when the interval between the first tape body 40 and the second tape body 60 on the side where the protrusion 30 is not present increases. Good. Therefore, before the interval between the first tape body 40 and the second tape body 60 on the side where the protrusion 30 is not present is widened, the protrusion 30 is connected to the side surface (arm) of the fitting female portion 50 as shown in FIG. 2, and the protrusion 30 may be separated from the fitting female part 50 (arm part 51) as shown in FIG. 2.
Further, the height of the protruding portion 30 is set so as to contact the side surface of the fitting female portion 50 when the interval between the first tape body 40 and the second tape body 60 on the side where the protruding portion 30 is not present is increased. Set as appropriate.

嵌合具１０の材料としては、各種樹脂が挙げられ、結晶性ポリオレフィン樹脂が好ましい。結晶性ポリオレフィン樹脂としては、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、エチレン−α−オレフィン共重合体等のポリオレフィン系共重合体等が挙げられる。
結晶性ポリオレフィン樹脂のメルトフローレート（ＪＩＳ Ｋ ７２１０）は、０．５〜２０ｇ／１０分が好ましい。メルトフローレートが０．５ｇ／１０分未満では、押出成形性が劣る。メルトフローレートが２０ｇ／１０分を超えると、形状安定性が劣る。 Examples of the material of the fitting 10 include various resins, and a crystalline polyolefin resin is preferable. Examples of the crystalline polyolefin resin include polyolefin copolymers such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer, and ethylene-α-olefin copolymer.
The melt flow rate (JIS K 7210) of the crystalline polyolefin resin is preferably 0.5 to 20 g / 10 minutes. When the melt flow rate is less than 0.5 g / 10 minutes, the extrusion moldability is poor. When the melt flow rate exceeds 20 g / 10 minutes, the shape stability is inferior.

嵌合具１０の材料には、必要に応じて、安定剤、酸化防止剤、滑剤、帯電防止剤、着色剤等の公知の添加剤を添加してもよい。
第１のテープ体本体４１および第２のテープ体本体６１は、単層であってもよく、他の層を有する多層であってもよい。他の層としては、ヒートシール層、耐熱層、バリア層等が挙げられる。 You may add well-known additives, such as a stabilizer, antioxidant, a lubricant, an antistatic agent, and a coloring agent, to the material of the fitting 10 as needed.
The first tape body main body 41 and the second tape body main body 61 may be a single layer or a multilayer having other layers. Examples of other layers include a heat seal layer, a heat resistant layer, and a barrier layer.

嵌合具１０は、例えば、押出機を用いて材料を溶融混練し、第１のテープ体４０の断面および第２のテープ体６０の断面と同じ形状の開口を有する異形ダイから溶融した材料を押出し、冷却固化することにより製造される。   The fitting tool 10 melts and kneads the material using an extruder, for example, and melts the material melted from a deformed die having the same shape as the cross section of the first tape body 40 and the cross section of the second tape body 60. It is manufactured by extruding and cooling and solidifying.

図３は、本発明の嵌合具付き袋体の一例を示す正面図であり、図４は、開口部近傍の断面図である。嵌合具付き袋体７０は、袋体本体８０と、嵌合具１０とを具備するものである。   FIG. 3 is a front view showing an example of the bag body with a fitting tool of the present invention, and FIG. 4 is a cross-sectional view in the vicinity of the opening. The bag body 70 with a fitting tool includes a bag body 80 and the fitting tool 10.

袋体本体８０は、例えば、２枚のフィルム８１を重ね、周縁の３辺をシール部８２にて溶着したものであり、周縁の１辺には開口部８３を有するものである。
フィルム８１は、単層であってもよく、多層であってもよい。図示例のフィルム８１は、基材層８４とヒートシール層８５とを有する２層フィルムである。基材層８４としては、結晶性ポリオレフィン樹脂、ポリエステル系樹脂、ポリアミド系樹脂、金属箔等が挙げられる。基材層８４は、単層であってもよく、多層であってもよい。ヒートシール層８５としては、ポリオレフィン樹脂、ポリエステル系樹脂等が挙げられる。 The bag body 80 is formed, for example, by laminating two films 81 and welding three peripheral edges with a seal portion 82, and having an opening 83 on one peripheral edge.
The film 81 may be a single layer or a multilayer. The film 81 in the illustrated example is a two-layer film having a base material layer 84 and a heat seal layer 85. Examples of the base material layer 84 include crystalline polyolefin resins, polyester resins, polyamide resins, and metal foils. The base material layer 84 may be a single layer or a multilayer. Examples of the heat seal layer 85 include polyolefin resins and polyester resins.

嵌合具１０は、突起部３０が嵌合雄部２０よりも開口部８３側となるように、袋体本体８０の開口部８３近傍の内面に取り付けられている。
嵌合具付き袋体７０は、例えば、２枚のフィルム８１の間に嵌合具１０を挟み、フィルム８１の周縁の３辺をシール部８２にてヒートシールによって溶着すると同時に、嵌合具１０をフィルム８１の内面にヒートシールによって溶着することによって製造される。 The fitting 10 is attached to the inner surface in the vicinity of the opening 83 of the bag body 80 so that the protrusion 30 is closer to the opening 83 than the fitting male 20.
For example, the bag 70 with a fitting tool sandwiches the fitting tool 10 between two films 81 and welds the three edges of the periphery of the film 81 by heat sealing at the seal portion 82. Is welded to the inner surface of the film 81 by heat sealing.

本発明の作用効果を充分に発揮させるためには、嵌合雄部２０が形成された面とは反対側の第１のテープ体本体４１の表面とフィルム８１の表面とが、嵌合雄部２０および突起部３０に対応する位置で少なくとも溶着していることが好ましい。同様に、嵌合雌部５０が形成された面とは反対側の第２のテープ体本体６１の表面とフィルム８１の表面とが、嵌合雌部５０に対応する位置で少なくとも溶着していることが好ましい。第１のテープ体本体４１とフィルム８１、および第２のテープ体本体６１とフィルム８１とは、第１のテープ体本体４１または第２のテープ体本体６１とフィルム８１との間に隙間が形成されて、該隙間に内容物等が入り込まないようにするために、全面で溶着されていることが特に好ましい。   In order to fully exhibit the effect of this invention, the surface of the 1st tape body main body 41 and the surface of the film 81 on the opposite side to the surface in which the fitting male part 20 was formed are a fitting male part. It is preferable that welding is performed at a position corresponding to 20 and the protrusion 30. Similarly, the surface of the second tape body 61 and the surface of the film 81 opposite to the surface on which the fitting female part 50 is formed are welded at least at a position corresponding to the fitting female part 50. It is preferable. The first tape body 41 and the film 81, and the second tape body 61 and the film 81 form a gap between the first tape body 41 or the second tape body 61 and the film 81. In order to prevent the contents and the like from entering the gap, it is particularly preferable that the entire surface is welded.

以上説明した嵌合具１０にあっては、突起部３０が、突起部３０がない側の第１のテープ体４０と第２のテープ体６０との間隔が拡がるときに、嵌合雌部５０の側面に当接するように設けられている。そのため、この嵌合具１０を、突起部３０が嵌合雄部２０よりも開口部８３側となるように、袋体本体８０の開口部８３近傍の内面に取り付けた嵌合具付き袋体７０にあっては、袋体本体８０の内圧に対する嵌合強度が高く、かつ袋体本体８０の開口部８３側からは容易に開封できる。   In the fitting 10 described above, when the gap between the first tape body 40 and the second tape body 60 on the side where the protrusion 30 does not exist is increased, the fitting female portion 50 is fitted. It is provided so that it may contact | abut. Therefore, this fitting 10 is attached to the inner surface in the vicinity of the opening 83 of the bag body 80 so that the protrusion 30 is closer to the opening 83 than the fitting male 20. In that case, the fitting strength of the bag body 80 with respect to the internal pressure is high, and the bag body 80 can be easily opened from the opening 83 side.

すなわち、図５に示すように、袋体本体８０の内側の内圧が高くなって袋体本体８０が膨らみ、第１のテープ体４０と第２のテープ体６０との間隔が拡がると、袋体本体８０の開口部８３側の第１のテープ体４０と第２のテープ体６０との間隔は狭くなる。このとき、第２の雄係止爪部２４と第２の雌係止爪部５４との引っ掛かりが維持された状態にあるため、嵌合雄部２０の幹部２１が開口部８３側に傾き、嵌合雌部５０のアーム部５１が開口部８３側に押されて変形し、雌係止爪部５３と雌係止爪部５４との隙間が拡がろうとする。しかし、開口部８３側の第１のテープ体４０と第２のテープ体６０との間隔は狭くなると、突起部３０が袋体本体８０の内側に傾くため、傾いた突起部３０によって、これに当接するアーム部５１が袋体本体８０の内側に押し戻され、雌係止爪部５３と雌係止爪部５４との隙間の拡がりを抑え、嵌合雄部２０の嵌合雌部５０からの脱離が抑制される。
一方、袋体本体８０の開口部８３側から開封する際には、突起部３０は嵌合雌部５０の側面に当接しないため、容易に開封できる。 That is, as shown in FIG. 5, when the internal pressure inside the bag body 80 increases and the bag body 80 swells and the distance between the first tape body 40 and the second tape body 60 increases, the bag body increases. The distance between the first tape body 40 and the second tape body 60 on the opening 83 side of the main body 80 is narrowed. At this time, since the hook between the second male locking claw portion 24 and the second female locking claw portion 54 is maintained, the trunk portion 21 of the fitting male portion 20 is inclined toward the opening 83 side, The arm part 51 of the fitting female part 50 is pushed and deformed toward the opening 83 side, and the gap between the female locking claw part 53 and the female locking claw part 54 tends to widen. However, when the gap between the first tape body 40 and the second tape body 60 on the opening 83 side is narrowed, the protrusion 30 is inclined toward the inside of the bag body 80, so that the inclined protrusion 30 causes The abutting arm portion 51 is pushed back to the inside of the bag body 80 to prevent the gap between the female locking claw portion 53 and the female locking claw portion 54 from expanding and from the fitting female portion 50 of the fitting male portion 20. Desorption is suppressed.
On the other hand, when opening from the opening 83 side of the bag body 80, the protruding portion 30 does not come into contact with the side surface of the fitting female portion 50, and therefore can be easily opened.

突起部３０が設けられていなければ、図６に示すように、第１のテープ体４０と第２のテープ体６０との間隔が拡がると、第２の雄係止爪部２４と第２の雌係止爪部５４との引っ掛かりが維持された状態にあるため、嵌合雄部２０の幹部２１が開口部８３側に傾き、嵌合雌部５０のアーム部５１が開口部８３側に押されて変形し、雌係止爪部５３と雌係止爪部５４との隙間が拡がってしまい、第２の雄係止爪部２４と第２の雌係止爪部５４との引っ掛かりが外れ、嵌合雄部２０が嵌合雌部５０から容易に脱離してしまう。   If the protrusion 30 is not provided, as shown in FIG. 6, when the distance between the first tape body 40 and the second tape body 60 is increased, the second male locking claw portion 24 and the second tape Since the engagement with the female locking claw 54 is maintained, the trunk portion 21 of the fitting male portion 20 is inclined toward the opening portion 83 side, and the arm portion 51 of the fitting female portion 50 is pushed toward the opening portion 83 side. As a result, the gap between the female locking claw 53 and the female locking claw 54 widens, and the second male locking claw 24 and the second female locking claw 54 are disengaged. The fitting male part 20 is easily detached from the fitting female part 50.

なお、本発明の嵌合具は、図示例のものに限定はされない。例えば、嵌合雄部が、第１のテープ体本体から略直角に立ち上がった２条の幹部を有し、それぞれの幹部の先端に、嵌合雌部側に突出した雄係止爪部が形成されたものであってもよい。また、嵌合雄部と嵌合雌部とからなるペアを、複数有する嵌合具であってもよい。   The fitting tool of the present invention is not limited to the illustrated example. For example, the fitting male part has two trunks that rise substantially perpendicularly from the first tape body, and a male locking claw that protrudes toward the fitting female part is formed at the tip of each trunk. It may be what was done. Moreover, the fitting tool which has multiple pairs which consist of a fitting male part and a fitting female part may be sufficient.
