Description

本発明は、袋体に関する。 The present invention relates to a bag body.

従来、袋体に詰め込んだ商品を展示した時や、輸送時、その他において、商品を収納した袋を故意に開封し、商品が改竄されることがある。
例えば、スーパーマーケットなどの小売店において、袋体に商品を詰め、その後、袋体に封をした後、売り場で展示することがある。
ここで、袋体に商品を詰め、その後に封をするために、袋体を開閉する手段として、ヒートシール装置を必要とせず簡易に充填するという観点から、袋本体の互いに対向する面に接合されたジッパーテープを用いることがある。
ジッパーテープは、雄部材と雌部材とが着脱自在とされた構造であるため、袋体に封をする作業と開封する作業が簡易に行えるという有利な点があるものの、袋体に封をして一度収納した後に、袋体を開封して商品を容易に取り出せるという不利な点もある。そのため、商品の改竄防止という点からは、ジッパーテープ付き袋体は利用しにくい。 Conventionally, when a product packed in a bag is displayed, transported, or otherwise, the bag containing the product is intentionally opened, and the product may be tampered with.
For example, in a retail store such as a supermarket, products may be packed in a bag and then sealed in a bag before being displayed at a sales floor.
Here, as a means for opening and closing the bag body to pack the product in the bag body and then sealing it, it is bonded to the mutually opposing surfaces of the bag body from the viewpoint of simply filling without requiring a heat seal device Zipper tape may be used.
Since the zipper tape has a structure in which the male member and the female member are detachable, there is an advantage in that the work of sealing the bag body and the work of opening the bag body can be easily performed, but the bag body is sealed. Once stored, the bag can be opened and the product can be easily taken out. Therefore, the bag body with a zipper tape is difficult to use from the viewpoint of preventing falsification of the product.

このようなジッパーテープ付き袋体において、改竄防止のための機能を備えた従来例が種々ある。
例えば、長手帯状の嵌合基部と、この嵌合基部の長手方向に沿って他部材が嵌合する渦巻き状の嵌合凹溝を有する係止部と、この係止部に接合し嵌合基部に連結する支持部とを備えた帯状係止部材がある（特許文献１）。
特許文献１では、一対の帯状係止部材が互いに嵌合することでジッパーテープとして機能する。係止部は、嵌合凹溝の一方の開口縁近傍に他部材と係合する内方に向けて突出する係合爪部を有する。支持部は、係止部との接合する位置が、係合爪部が他部材に係合する係合位置から嵌合基部に向けた垂線よりも、嵌合凹溝の他方の開口縁側に変位した位置に設けられている。支持部は、係止部が他部材と嵌合した状態から互いに離間する方向に引っ張り力を作用させて嵌合状態が解除される強度より小さい強度に形成される。 In such a bag body with a zipper tape, there are various conventional examples having a function for preventing falsification.
For example, a fitting base having a longitudinal band-like fitting base, a locking portion having a spiral fitting concave groove into which another member is fitted along the longitudinal direction of the fitting base, and a fitting base joined to the locking portion. There is a belt-like locking member provided with a support portion connected to the dome (Patent Document 1).
In patent document 1, it functions as a zipper tape by a pair of band-shaped locking members fitting each other. The locking portion has an engaging claw portion that protrudes inward to engage with another member in the vicinity of one opening edge of the fitting groove. The support portion is displaced from the engagement position where the engagement claw portion engages with the other member toward the fitting base to the other opening edge side of the fitting groove, with respect to the fitting base. It is provided at the position. The support portion is formed with a strength smaller than the strength at which the engagement state is released by applying a pulling force in a direction away from the state in which the locking portion is engaged with the other member.

特開２０１１−３６６４２号公報JP 2011-36642 A

特許文献１で示される従来例では、一対の帯状係止部材を一度嵌合した後に開封しようとすると、嵌合する係止部同士に剪断応力が作用して係合爪部が互いに咬み込む状態となり、開封しにくくなる。
しかし、特許文献１で示される従来例では、ジッパーテープが複雑な形状であるため、製造が困難であるとともに、搬送時に破損しないように注意が必要となる。
また、特許文献１で示される従来例では、無理やりジッパーテープを開封しようとしてさらに強い力を加えると、係止部が損傷したり、支持部が切断されたりすることで開封できてしまうという不具合があった。つまり、特許文献１で示される従来例は、封入後に開封状態を判断するのみであって、改竄のために、開封自体を阻止するものではない。
袋が開封されてしまったのでは、商品の改竄対策としては十分とはいえない。 In the conventional example shown in Patent Document 1, when a pair of band-shaped locking members are once fitted and then opened, shearing stress acts on the engaging portions to be engaged, and the engaging claw portions bite each other. It becomes difficult to open.
However, in the conventional example shown in Patent Document 1, since the zipper tape has a complicated shape, it is difficult to manufacture and care must be taken so as not to be damaged during transportation.
In addition, in the conventional example shown in Patent Document 1, when a stronger force is applied to forcefully open the zipper tape, the locking portion is damaged or the support portion is cut, so that it can be opened. there were. In other words, the conventional example shown in Patent Document 1 only determines the opened state after sealing, and does not prevent the opening itself for tampering.
If a bag is opened, it cannot be said that it is sufficient as a countermeasure against tampering of products.

本発明の目的は、物品の改竄の防止を確実に行える袋体を提供することにある。 An object of the present invention is to provide a reliably performed that bag to prevent falsification of the article.

The male tape member includes a male belt base disposed opposite to the female belt base, a male member provided on the male belt base and engaged with the female member, and the male member. Provided side by side in the width direction and locked to the female side collar And one of the female side belt-like base and the male side belt-like base is joined to the inner surface of the bag body with an edge on the opening end side and an edge on the storage space side, The other of the female side belt-like base and the male side belt-like base is a region excluding a region where any of the female member and the female side collar, and the male member and the male side collar is provided. The region including the edge on the storage space side is joined to the inner surface of the bag body, the female member has a female claw portion protruding in the width direction and facing each other, and the male member is , Having a pair of male claw portions that protrude in opposite directions in the width direction and are locked to the female claw portion, and are opposite to the male side collar portion of the pair of male claw portions The male claw that faces the side has a hypotenuse that engages with the female claw, and is perpendicular to the normal of the male belt-like base Wherein the male barb θ angle of the hypotenuse of the male claw portion facing the opposite side is less than 90 °, the female hook portion protrudes hypotenuse is formed toward only one of the width direction having a female side鉤用claw portion, the angle of the hypotenuse of the female-side鉤用claw portion relative to the normal of the female strip-like base portion α is less than 90 °, the male hook portion is the width direction A male side hook claw portion formed with a hypotenuse that protrudes only toward one side and engages with the hypotenuse of the female side hook claw portion; the hypotenuse of the angle beta, less than 90 ° der is, in the female hook or the male hook provided on the other of said female strip-like base portion and the male-side strip-like base portion, said female鉤用pawl parts or projecting direction of the male鉤用claw section is characterized direction der Rukoto toward the housing space side.

この発明では、幅方向の一方からジッパーテープを開けようとすると、雌側テープ部材と雄側テープ部材とが相対的に動くことになる。これにより、例えば、雌側鉤用爪部と、雄側鉤用爪部とが互いに係止されるとともに、雌部材のうち雌側鉤用爪部と同じ方向に向く雌側爪部と、雄部材のうち雄側鉤用爪部と同じ方向に向く雄側爪部とが互いに係止されることになる。
幅方向の他方からジッパーテープを開けようとすると、雌部材の雌側鉤用爪部とは反対側に向く雌側爪部と、雄部材の雄側鉤用爪部とは反対側に向く雄側爪部とが互いに係止される。
しかも、一対の雄側爪部のうち雄側鉤部とは反対側に向いた雄側爪部の斜辺の雄側帯状基部の垂線に対する角度θが９０°未満であり、雌側鉤用爪部と雄側鉤用爪部との斜辺の帯状基部の垂線に対する角度α，βが９０°未満であるため、これらが幅方向のいずれの方向からも外れにくくなる。
すなわち、この発明では、ジッパーテープを幅方向の両側からそれぞれ開封しようとしても、雌側テープ部材と雄テープ部材とが互いに離れない構成となっている。そのため、袋本体に接合されたジッパーテープが一度封止した後では、ジッパーテープが開封されることがない。このジッパーテープを袋体に用いれば、物品の改竄の防止が確実に行えることになる。
また、この発明に係る袋体は、雌側帯状基部と雄側帯状基部との一方が、開口端側の端縁および収納空間側の端縁が袋本体の内面に接合されるのに対して、雌側帯状基部と雄側帯状基部との他方が、雌部材および雌側鉤部と、雄部材および雄側鉤部とのいずれかが設けられた領域を除いた領域において、収納空間側の端縁を含む領域のみが袋本体の内面に接合される、いわゆる片側外しの構成となっている。この片側外しの構成によって、袋本体の開口端側からジッパーテープを開封しようとすると、雌側帯状基部と雄側帯状基部とに剪断させる方向に力が作用する。この力は、雌側鉤用爪部と雄側鉤用爪部とが互いに係止するとともに、雌部材と雄部材とが互いに咬合する方向となり、これらが互いに確実に係止されることになる。このような片側外しの構成を採用することによって、開口端側からのジッパーテープの開封を確実に阻止できるので、物品の改竄がより確実に防止される。 In the present invention, when you open the one or radio Ppatepu the width direction, so that the female-side tape member and the male-side tape member moves relatively. Thus, for example, the female side hook claw and the male side hook claw are locked to each other, and the female side claw part facing the same direction as the female side hook claw of the female member, and the male Of the members, the male claw portions that face in the same direction as the male claw portions are locked together.
If you open the other or radio Ppatepu in the width direction, toward the side opposite to the female-side claw portion facing the opposite side to the female side鉤用claw portion of the female member, the male鉤用claw portion of the male member The male claw part is locked with each other.
In addition, the angle θ of the hypotenuse of the male claw portion facing the opposite side of the male claw portion of the pair of male claw portions with respect to the perpendicular of the male band base portion is less than 90 °, and the female claw portion for female heel Since the angles α and β with respect to the perpendicular of the band-like base portion of the hypotenuse of the claw portion for the male side collar and the male side heel claw portion are less than 90 °, they are difficult to come off from any direction in the width direction.
That is, in this invention, even if an attempt is open each di Ppatepu from both sides in the width direction, has a structure in which the female-side tape member and the male tape member is not separated from each other. Therefore, after the di Ppatepu joined to the bag body is sealed once sealing is never di Ppatepu is opened. The use of this di Ppatepu the bag, so that can be reliably performed is prevented tampering of the article.
Further, in the bag according to the present invention, one of the female side belt-like base and the male side belt-like base is bonded to the inner surface of the bag body at the opening edge side and the storage space side edge. The other of the female side belt-like base and the male side belt-like base is on the side of the storage space except for the region where either the female member or the female side collar and the male member or the male side collar is provided. Only the region including the end edge is joined to the inner surface of the bag body, so-called one-side removal configuration. When the zipper tape is to be opened from the opening end side of the bag body with this one-side removal configuration, a force acts in the direction of shearing the female side belt-like base and the male side belt-like base. This force is such that the female heel claw and the male heel claw are engaged with each other, and the female member and the male member are engaged with each other, so that they are securely engaged with each other. . By adopting such a one-side removal configuration, it is possible to reliably prevent the zipper tape from being opened from the open end side, so that tampering of the articles can be prevented more reliably.

本発明では、前記雌部材において互いに向かい合う方向に突出した前記雌側爪部は、前記雄側爪部に係合する斜辺を有し、前記雌側帯状基部の垂線に対する前記雌側爪部の斜辺の角度Ａ，Ｂは、それぞれ９０°未満である構成が好ましい。また、前記一対の雄側爪部のうち前記雄側鉤部側を向く雄側爪部は、前記雌側爪部に係合する斜辺を有し、前記雄側帯状基部の垂線に対する、前記雄側鉤部側を向く前記雄側爪部の斜辺の角度Ｃは、９０°未満である構成が好ましい。
これらの構成では、雄部材と雌部材とは、幅方向のいずれの方向からもより外れにくくなる。 In the present invention, wherein the female-side claw portion protruding face each other direction in the female member has a hypotenuse which engages with the male claw portion, front Kimesu side strip-like base portion normal to the female-side claw portions of the It is preferable that the hypotenuse angles A and B are each less than 90 °. Also, male claw portion facing the male hook side of the front Symbol pair of male claw portion has a hypotenuse which engages with the female-side claw portion, relative to the normal of the front Kieu side strip-like base portion, The angle C of the hypotenuse of the male claw part facing the male heel part side is preferably less than 90 °.
In these configurations, the male member and the female member are less likely to come off from any direction in the width direction.

本発明では、前記雄部材は、前記雄側帯状基部の平面から突出した突出部を有し、前記突出部の先端には、前記雄側爪部が一体に設けられている構成が好ましい。

In this configuration, since the male member is composed of the protruding portion and the pair of male claw portions, the male tape member can be easily formed by extrusion molding or the like.

本発明では、前記雌部材および前記雄部材は、それぞれポリプロピレンで形成されていることが好ましい。
この構成では、ポリプロピレンという、ポリエチレンなどに比べて硬質な材料で雌部材や雄部材を形成するので、改竄防止用ジッパーテープの開封が困難なものとなる。 In the present invention, the female member and the male member is preferably formed of polypropylene, respectively.
In this configuration, as polypropylene, because it forms a female member and a male member of a hard material as compared with polyethylene, it becomes the opening of the tamper prevention zipper tape difficult.

本発明では、前記幅方向における前記雌側帯状基部の寸法は、前記幅方向における前記雄側帯状基部の寸法より短く、前記雌側鉤部側に位置する前記雌側帯状基部の端縁Ｐ１と、当該雌側鉤部の端縁Ｐ２との間の寸法、および、前記雌側鉤部とは反対側に位置する前記雌側帯状基部の端縁Ｐ１と、前記雌部材の前記雌側鉤部とは反対側の端縁Ｐ２との間の寸法のいずれかの寸法は、０ｍｍ以上２．０ｍｍ以下である構成としてもよく、あるいは、前記幅方向における前記雄側帯状基部の寸法は、前記幅方向における前記雌側帯状基部の寸法より短く、前記雄側鉤部側に位置する前記雄側帯状基部の端縁Ｐ１と、当該雄側鉤部の端縁Ｐ２との間の寸法、および、前記雄側鉤部とは反対側に位置する前記雄側帯状基部の端縁Ｐ１と、前記雄部材の前記雄側鉤部とは反対側の端縁Ｐ２との間の寸法のいずれかの寸法は、０ｍｍ以上２．０ｍｍ以下である構成としてもよい。
この構成では、雌側テープ部材と雄側テープ部材とを互いに開こうとしても、端縁Ｐ１と端縁Ｐ２との間の寸法が短いので、雌側テープ部材や雄側テープ部材自体を把持することができない。そのため、物品の改竄が確実に防止される。 In the present invention, the dimensions of the female-side strip-like base portion which definitive before Symbol width direction, the definitive widthwise the short rather than the size of the male-side strip-like base portion, the female-side strip-like base portion located on the female side hook side end edge P1, dimension between the edge P2 of the female hook, and the edge P1 of the female-side strip-like base portion located on the opposite side to the female side hook, the said female member one of the dimensions of the dimension between the opposite side edge P2 and the female hook portion may be configured at 2.0mm less than 0 mm, or the male strip base definitive before Symbol width direction the dimensions, the short rather than the size of the female-side strip-like base portion which definitive in the width direction, the edge P1 of the male-side strip-like base portion located on said male hook portion side, the end edge P2 of the male hook dimension between, and, said the male hook and the edge P1 of the male-side strip-like base portion located on the opposite side, of the male member One of the dimensions of the dimension between the opposite side edge P2 and Kieu side hook may be configured at 2.0mm less than 0 mm.
In this configuration, even if an attempt is made to open the female tape member and the male tape member, the dimension between the end edge P1 and the end edge P2 is short, so the female side tape member or the male side tape member itself is gripped. I can't. Therefore, falsification of the article is surely prevented.

これら寸法が２．０ｍｍを超えると、人によっては、雄側テープ部材や雌側テープ部材を把持できることになる。どんな人でも、雄側テープ部材や雌側テープ部材を把持できないようにするために、この寸法差は短いほどよい。 When these dimensions exceeds 2.0 mm, some people will be able to grip the male tape member or female tape member. In order to prevent any person from gripping the male tape member and the female tape member, it is better that this dimensional difference is short.

端縁Ｐ１と端縁Ｐ２との間の寸法差ｔは、０．０ｍｍ以上２．０ｍｍ以下であり、これは、人の指で把持できない距離である。
大人、子供、男性、女性などや、年齢や健康状態などによって、手で物をつかむ強さに差異がある。例えば、指先の器用な健康な成人男性であれば、指先の力が強いため、指で把持する領域の距離が短くてもよいが、子供や高齢者では、指先の力が弱いため、当該距離を長くする必要がある。これらの条件を考慮すると、人の指で把持できない距離（寸法差ｔ）は、０．０ｍｍ以上２．０ｍｍ以下が普遍的な値となる。寸法差ｔが２．０ｍｍを超えると、多くの人にとって、雄側帯状基部４２の開口端側を把持できることになる。 The edge P1 on the opening end side of the male side belt-like base portion 42 and the edge P2 on the opening end side of the protruding portion 620 of the male member M are substantially flush with each other.
The dimensional difference t between the edge P1 and the edge P2 is 0.0 mm or more and 2.0 mm or less, which is a distance that cannot be gripped by a human finger.
There are differences in the strength of grabbing objects by hand depending on adults, children, men, women, etc., and age and health status. For example, in the case of a dexterous healthy adult male fingertip, the fingertip force is strong, so the distance of the area gripped by the finger may be short, but in children and the elderly, the fingertip force is weak, so the distance Need to be long. Considering these conditions, the distance that cannot be grasped by a human finger (dimension difference t) is a universal value between 0.0 mm and 2.0 mm. If the dimensional difference t exceeds 2.0 mm, for many people, the opening end side of the male side belt-like base portion 42 can be gripped.

FIG.
Thereafter, the base film 11 is bent to form the side seal portion 10A by heat sealing, and the bottom seal portion 10B is formed as necessary. Then, the cutting part 30 for opening is provided in the bag main body 10.

（物品の収納方法）
ジッパーテープ付き袋体２が製造されたら、改竄防止用ジッパーテープ付き袋体２を小売店などに搬送する。
改竄防止用ジッパーテープ付き袋体２を搬送する際に、雌側テープ部材２１と雄側テープ部材２２とが誤って咬合しないようにするために、これらの間に、例えばフィルム（図示せず）を介装しておく。
小売店などでは、図５（Ａ）に示される通り、フィルムを取り除くとともに、袋本体１０の開口端１２を開放する。そして、図５（Ｂ）に示される通り、袋本体１０の収納空間１３に物品Ｇを収納する。物品Ｇを収納する際には、袋本体１０の開口端１２が開放されたままとする。 (How to store goods)
When the bag body 2 with a zipper tape is manufactured, the bag body 2 with a zipper tape for preventing falsification is transported to a retail store or the like.
In order to prevent the female tape member 21 and the male tape member 22 from being accidentally engaged when the bag body 2 with the zipper tape for preventing falsification is conveyed, for example, a film (not shown) is interposed between them. I will intervene.
In a retail store or the like, as shown in FIG. 5A, the film is removed and the opening end 12 of the bag body 10 is opened. Then, as shown in FIG. 5B, the article G is stored in the storage space 13 of the bag body 10. When the article G is stored, the open end 12 of the bag body 10 is left open.

図５（Ｃ）に示される通り、物品Ｇが収納されたら、ジッパーテープ２０の一端から他端に向けて、雌側テープ部材２１と雄側テープ部材２２とを互いに係合する。雌側テープ部材２１と雄側テープ部材２２とを互いに押し込むことにより、雌側テープ部材２１の雌部材Ｆに雄側テープ部材２２の雄部材Ｍが嵌り込み、雌側テープ部材２１と雄側テープ部材２２とが互いに係合する。これにより、図５（Ｄ）に示される通り、物品Ｇが収納空間１３に収納された改竄防止袋１が完成する。
完成した改竄防止袋１を販売するために、売り場に展示する。 As shown in FIG. 5C, when the article G is stored, the female tape member 21 and the male tape member 22 are engaged with each other from one end of the zipper tape 20 toward the other end. By pushing the female tape member 21 and the male tape member 22 together, the male member M of the male tape member 22 fits into the female member F of the female tape member 21, and the female tape member 21 and the male tape are inserted. The members 22 engage with each other. Thereby, as shown in FIG. 5D, the tamper-proof bag 1 in which the article G is stored in the storage space 13 is completed.
In order to sell the completed anti-tamper bag 1, it will be displayed at the sales floor.

売り場にて、商品を改竄しようとする者が改竄防止袋１の袋本体１０の開口端１２の近傍を持って引っ張っても、ジッパーテープ２０を開けることができない。
つまり、図４に示される通り、袋本体１０の開口端１２の近傍が引っ張られることで、雌側テープ部材２１が開口端側に向けた方向Ｑ１に引っ張られる。これに対して、雄側テープ部材２２は、雄側帯状基部４２の収納空間側の一部のみが袋本体１０の内面に接合されるので、雌側テープ部材２１とは反対側の方向Ｑ２に引っ張られる。すると、雌側帯状基部４１と雄側帯状基部４２とに剪断させる方向に力が作用する。
この力により、雌側鉤用爪部６１１と雄側鉤用爪部６２２とが互いに係合し、さらに、雌部材Ｆの収納空間側の雌側爪部５１１と雄部材Ｍの収納空間側の雄側爪部５２２とが互いに係合することになる。
なお、雄側帯状基部４２の開口端側の長さは短いので、雄側テープ部材２２自体を把持することができない。 The zipper tape 20 cannot be opened even if a person who intends to tamper with the product pulls in the vicinity of the opening end 12 of the bag body 10 of the tamper-proof bag 1 at the sales floor.
That is, as shown in FIG. 4, when the vicinity of the opening end 12 of the bag body 10 is pulled, the female tape member 21 is pulled in the direction Q <b> 1 toward the opening end. On the other hand, the male tape member 22 is joined to the inner surface of the bag body 10 only in part of the storage space side of the male band base 42 in the direction Q2 opposite to the female tape member 21. Be pulled. Then, a force acts in a direction in which the female side belt-like base portion 41 and the male side belt-like base portion 42 are sheared.
By this force, the female side hook claw 611 and the male side hook claw 622 are engaged with each other, and further, the female side claw 511 on the storage space side of the female member F and the storage space side of the male member M on the storage space side. The male claw portion 522 is engaged with each other.
In addition, since the length by the side of the opening end of the male side strip | belt-shaped base 42 is short, the male side tape member 22 itself cannot be hold | gripped.

一方、袋本体１０の収納空間側からジッパーテープ２０を開けようとしても開封できない。つまり、開封に際して、雌側鉤部６１と雄側鉤部６２とが互いに離れる方向に動こうとしても、これらの斜辺Ｌの垂線Ｓに対する角度α，βが９０°未満であるため、雌側鉤部６１と雄側鉤部６２とが互いに離れにくくなる。しかも、雌部材Ｆを構成する雌側爪部５１１と雄部材Ｍを構成する雄側爪部５２２とが互いに係止される。
売り場にて、物品Ｇが収納された改竄防止袋１を購入した消費者は、改竄防止用ジッパーテープ２０自体を開けることができないので、物品Ｇを取り出すために、開封用切断部３０により、袋本体１０を切断する。 On the other hand, even if the zipper tape 20 is opened from the storage space side of the bag body 10, it cannot be opened. That is, at the time of opening, even if the female side collar 61 and the male side collar 62 try to move away from each other, the angles α and β with respect to the perpendicular S of the hypotenuse L are less than 90 °. It becomes difficult for the part 61 and the male side collar part 62 to mutually separate. In addition, the female claw portion 511 constituting the female member F and the male claw portion 522 constituting the male member M are locked together.
Since the consumer who purchased the tamper-proof bag 1 in which the item G is stored at the sales floor cannot open the tamper-proof zipper tape 20 itself, in order to take out the item G, the opening cutting unit 30 removes the bag. The main body 10 is cut.

The male member M has a pair of male claw portions 522 protruding in opposite directions in the width direction, and the male claw portion facing the opposite side of the male side collar portion 62 among these male side claw portions 522 522 is configured to have a hypotenuse L that engages the female claw 511. The angle θ of the hypotenuse L with respect to the normal S of the male side belt-like base portion 42 was less than 90 °. Further, the angle α between the oblique side L of the female side hook claw 611 constituting the female side collar 61 and the perpendicular S is less than 90 °, and the hypotenuse of the male side hook claw 622 constituting the male side collar 62 The angle β between L and the perpendicular S was less than 90 °.
Therefore, since the female tape member 21 and the male tape member 22 are not separated from each other even if the zipper tape 20 is opened from both sides in the width direction, after the zipper tape 20 is once sealed, , Never opened.
Furthermore, the female side claw part 511 protruding in the direction in which the female member F faces each other has angles A and B with respect to the perpendicular of the female side belt-like base part 41 of the hypotenuse engaging with the male side claw part 522, respectively. Since the angle C of the hypotenuse of the male claw part 522 facing the male collar part 62 side of the male member M with respect to the perpendicular of the male belt-like base part 42 is less than 90 °, the male member M and the female member F have a width of It becomes more difficult to come off from any direction.
Therefore, the use of the zipper tape 20 as the tamper-proof bag 1 can surely prevent the tampering of the article.

（２）雄部材Ｍを、突出部５２０と、この突出部５２０と一体に形成した一対の雄側爪部５２２とから構成するので、雄側テープ部材２２を、押出成形などによって、容易に成形することができる。 (2) Since the male member M is composed of the protruding portion 520 and the pair of male claw portions 522 formed integrally with the protruding portion 520, the male tape member 22 is easily formed by extrusion molding or the like. can do.

（３）雌部材Ｆおよび雄部材Ｍを、それぞれポリプロピレンという硬質な材料で成形すれば、雌部材Ｆおよび雄部材Ｍが変形しにくいため、ジッパーテープ２０の開封が困難なものとなる。 (3) If the female member F and the male member M are each formed of a hard material called polypropylene, the female member F and the male member M are not easily deformed, so that the zipper tape 20 is difficult to open.

（４）雄側帯状基部４２の幅方向の一方の端縁Ｐ１（開口端側）と、雄部材Ｍの突出部５２０の端縁Ｐ２とを略面一とした。端縁Ｐ１と端縁Ｐ２とに寸法差ｔがある場合でも、この寸法差ｔを、人の指で把持できない距離である、０．０ｍｍ以上２．０ｍｍ以下とした。そのため、当該幅方向の一方から雌側テープ部材２１と雄側テープ部材２２とを互いに開こうとしても、雄側帯状基部４２の端縁から雄部材Ｍの端縁までの寸法差ｔが短いので、雄側帯状基部４２自体を把持することができない。従って、物品の改竄を確実に防止することができる。 (4) One end edge P1 (opening end side) in the width direction of the male side belt-like base portion 42 and the end edge P2 of the protruding portion 520 of the male member M are substantially flush. Even when there is a dimensional difference t between the edge P1 and the edge P2, the dimensional difference t is set to 0.0 mm or more and 2.0 mm or less, which is a distance that cannot be gripped by a human finger. Therefore, even if the female tape member 21 and the male tape member 22 are opened from one side in the width direction, the dimensional difference t from the edge of the male band base 42 to the edge of the male member M is short. The male side belt-like base 42 itself cannot be gripped. Therefore, tampering of the article can be reliably prevented.

（５）ジッパーテープ付き袋体２を、袋本体１０と、袋本体１０の内面に接合された前述の構成の改竄防止用ジッパーテープ２０とを備えて構成した。雌側帯状基部４１の開口端側の端縁から収納空間側の端縁に渡った領域を袋本体１０の内面に接合し、雄側帯状基部４２の雄部材Ｍおよび雄側鉤部６２が設けられた領域を除いた領域であって収納空間側の端縁を含む接合領域Ｅを袋本体１０の内面に接合した。
そのため、雄側帯状基部４２を収納空間側の一部のみが袋本体１０の内面に接合される、いわゆる片側外しの構成となっているから、袋本体１０の開口端側からジッパーテープ２０を開封しようとすると、雌部材Ｆの開口端側に向いた雌側爪部５１１と雄部材Ｍの収納空間側に向いた雄側爪部５２２とが互いに係止され、雌側鉤用爪部６１１と雄側鉤用爪部６２２とが互いに係止されるので、物品の改竄がより確実に防止される。 (5) The bag body 2 with a zipper tape was configured to include the bag body 10 and the zipper tape 20 for preventing tampering having the above-described configuration joined to the inner surface of the bag body 10. A region extending from the opening edge side edge of the female band base 41 to the storage space side edge is joined to the inner surface of the bag body 10, and the male member M and the male collar 62 of the male band base 42 are provided. The joining area E, which is an area excluding the created area and includes the edge on the storage space side, was joined to the inner surface of the bag body 10.
Therefore, since the male side belt-like base portion 42 has a so-called one-side removal structure in which only a part on the storage space side is joined to the inner surface of the bag body 10, the zipper tape 20 is opened from the opening end side of the bag body 10. If it tries, the female side nail | claw part 511 which faced the opening end side of the female member F and the male side nail | claw part 522 which faced the storage space side of the male member M will be mutually latched, Since the male side hook claw 622 is locked to each other, tampering of the article is more reliably prevented.

（６）袋本体１０には、ジッパーテープ２０より収納空間側に開封用切断部３０が設けられているから、商品を正規に購入した消費者などが、物品の取り出しが容易に行える。 (6) Since the bag body 10 is provided with the cutting section 30 for opening on the side of the storage space from the zipper tape 20, a consumer or the like who has purchased the product can easily take out the product.

［第２実施形態］
次に、本発明の第２実施形態を図６に基づいて説明する。
（ジッパーテープの構成）
第２実施形態は、ジッパーテープの構成が第１実施形態とは異なる。

One direction (upper) in the width direction is the opening end side, and the other direction (lower) in the width direction is the storage space side. In the second embodiment, the female tape member 71 is disposed on the left side of FIG. 6 and the male tape member 72 is disposed on the right side of FIG.

第２実施形態では、第１実施形態と同様に、雌側テープ部材７１は、雌側帯状基部４１と、雌側帯状基部４１の幅方向に並んで設けられた雌部材Ｆおよび雌側鉤部６１とを備えて構成されている。
雄側テープ部材７２は、雄側帯状基部４２と、雄側帯状基部４２に幅方向に並んで設けられた雄部材Ｍおよび雄側鉤部６２とを備えて構成されている。
第２実施形態では、第１実施形態と同様に、雌側鉤部６１は、雌側帯状基部４１の平面から突出した突出部６１０と、この突出部６１０の先端から雌部材Ｆ（袋本体１０の収納空間１３側）にのみ向けて突出した雌側鉤用爪部６１１とを有する。
雄側鉤部６２は、雄側帯状基部４２の平面から突出した突出部６２０と、この突出部５６０の先端から雄部材Ｍとは反対側（袋体の開口端１２側）にのみ向けて突出し雌側鉤用爪部６１１と係止する雄側鉤用爪部６２２とを有する。
雌部材Ｆの互いに向かい合う方向に突出した雌側爪部５１１は、雄側爪部５２２に係合する斜辺の雌側帯状基部４１の垂線に対する角度Ａ，Ｂがそれぞれ９０°未満である。雄部材Ｍの雄側鉤部６２側に向いた雄側爪部５２２の斜辺の雄側帯状基部４２の垂線に対する角度Ｃが９０°未満である。これにより、雄部材Ｍと雌部材Ｆとは、幅方向のいずれの方向からもより外れにくくなる。 In the second embodiment, similar to the first embodiment, the female-side tape member 71 includes a female-side belt-like base portion 41, a female member F and a female-side flange portion provided side by side in the width direction of the female-side belt-like base portion 41. 61.
The male-side tape member 72 includes a male-side belt-like base portion 42, and a male member M and a male-side flange portion 62 provided on the male-side belt-like base portion 42 so as to be arranged in the width direction.

Female side claw portion 611 protruding only toward the storage space 13 side).
The male side collar 62 projects from the flat surface of the male side belt-like base 42 and the projection 560 from the tip of the projection 560 toward only the side opposite to the male member M (opening end 12 side of the bag body). It has a female side hook claw 611 and a male side hook claw 622 to be locked.
The female side claw portion 511 protruding in the direction in which the female member F faces each other has angles A and B with respect to the perpendicular of the female side band-like base portion 41 on the hypotenuse that engages with the male side claw portion 522, respectively. The angle C of the hypotenuse of the male claw part 522 facing the male collar part 62 side of the male member M with respect to the perpendicular of the male band base 42 is less than 90 °. Thereby, the male member M and the female member F are less likely to come off from any direction in the width direction.

第２実施形態では、第１実施形態とは異なり、雌部材Ｆが収納空間側に配置され、雌側鉤部６１が開口端側に配置されている。同様に、雄部材Ｍが収納空間側に配置され、雄側鉤部６２が開口端側に配置されている。
雌側鉤部６１と雄側鉤部６２とは、斜辺Ｌの垂線Ｓに対する角度α，βが９０°未満である。これにより、開口端側からの開封がしにくい構成となる。
雌側帯状基部４１の幅方向の寸法が雄側帯状基部４２の幅方向の寸法より短い。
雌側帯状基部４１の開口端側端縁Ｐ１と雌側鉤部６１の突出部６１０の端縁Ｐ２とは略面一である。端縁Ｐ１と端縁Ｐ２との寸法差ｔは、０．０ｍｍ以上２．０ｍｍ以下、つまり、人の指で把持できない距離である。雌側帯状基部４１の端縁Ｐ１から雌側鉤部６１の端縁Ｐ２までの寸法差ｔが短いので、雌側帯状基部４１自体を把持することができない。
雄側帯状基部４２の開口端側の端縁から収納空間側の端縁に渡った領域を袋本体１０の内面に接合し、雌側帯状基部４１の雌側鉤部６１および雌部材Ｆが設けられた領域を除いた領域であって収納空間側の端縁を含む接合領域Ｅを袋本体１０の内面に接合した。そのため、雌側帯状基部４１を収納空間側の一部のみが袋本体１０の内面に接合される、いわゆる片側外しの構成となっている。 In the second embodiment, unlike the first embodiment, the female member F is disposed on the storage space side, and the female side flange 61 is disposed on the opening end side. Similarly, the male member M is arrange | positioned at the storage space side, and the male side collar part 62 is arrange | positioned at the opening end side.
In the female side collar 61 and the male side collar 62, the angles α and β with respect to the perpendicular S of the hypotenuse L are less than 90 °. Thereby, it becomes the structure which is hard to open from the opening end side.
The dimension in the width direction of the female band-shaped base 41 is shorter than the dimension in the width direction of the male band-shaped base 42.
The opening end side edge P1 of the female side belt-like base 41 and the end edge P2 of the protruding part 610 of the female side collar 61 are substantially flush. The dimensional difference t between the edge P1 and the edge P2 is 0.0 mm or more and 2.0 mm or less, that is, a distance that cannot be gripped by a human finger. Since the dimensional difference t from the edge P1 of the female band base 41 to the edge P2 of the female flange 61 is short, the female band base 41 itself cannot be gripped.
A region extending from the opening edge side edge of the male side belt-like base portion 42 to the end edge on the storage space side is joined to the inner surface of the bag body 10, and the female side flange portion 61 and the female member F of the female side belt-like base portion 41 are provided. The joining area E, which is an area excluding the created area and includes the edge on the storage space side, was joined to the inner surface of the bag body 10. Therefore, the female-side belt-like base 41 has a so-called one-side removed configuration in which only a part on the storage space side is joined to the inner surface of the bag body 10.

The dimensional difference t between the edge P1 and the edge P2 is 0.0 mm or more and 2.00 mm or less, that is, a distance that cannot be gripped by a human finger. Thereby, since the dimensional difference t from the edge P1 of the female side strip base 41 to the end P2 of the female member F is short, the female side strip base 41 itself cannot be gripped.
A region extending from the edge on the opening end side of the male side belt-like base 42 to the edge on the storage space side is joined to the inner surface of the bag body 10, and the female member F and the female side flange 61 of the female side belt-like base 41 are provided. The joining area E, which is an area excluding the created area and includes the edge on the storage space side, was joined to the inner surface of the bag body 10. Therefore, the female-side belt-like base 41 has a so-called one-side removed configuration in which only a part on the storage space side is joined to the inner surface of the bag body 10.

The dimensional difference t between the edge P1 and the edge P2 is 0.0 mm or more and 2.00 mm or less, that is, a distance that cannot be gripped by a human finger. Thereby, since the dimensional difference t from the edge P1 of the male side band-shaped base 42 to the edge P2 of the male side collar 62 is short, the female side band-shaped base 41 itself cannot be gripped.

（第４実施形態の効果）
第４実施形態では、第１実施形態の効果（１）〜（６）と同様の効果を奏することができる。 (Effect of 4th Embodiment)
In the fourth embodiment, the same effects as the effects (1) to (6) of the first embodiment can be achieved.

［実施形態の変形］
なお、以上説明した態様は、本発明の一態様を示したものであって、本発明は、前記した実施形態に限定されるものではなく、本発明の構成を備え、目的および効果を達成できる範囲内での変形や改良が、本発明の内容に含まれるものであることはいうまでもない。 [Modification of Embodiment]
The aspect described above shows one aspect of the present invention, and the present invention is not limited to the above-described embodiment, and has the configuration of the present invention and can achieve the object and effect. It goes without saying that modifications and improvements within the scope are included in the content of the present invention.

例えば、前記各実施形態では、雄部材Ｍを、突出部５２０の先端にそれぞれ一対の雄側爪部２２２を一体に設けて構成したが、本発明では、雄部材Ｍを幅方向に沿って分けた構成としてもよい。
つまり、図９で示される通り、雄部材Ｍの突出部５２０を開口端側と収納空間側とにそれぞれ設け、これらの突出部５２０の先端にそれぞれ雄側爪部５２２を一体に形成したフック部５２Ａ，５２Ｂから雄部材Ｍを構成してもよい。この場合、幅方向に並んだ突出部５２０は、寸法ｍだけ離れている。開口端側の雌構成部５１と開口端側のフック部５２Ａとが対となり、収納空間側の雌構成部５１と収納空間側のフック部５２Ｂとが対となる。
また、前記各実施形態では、雌部材Ｆと雄部材Ｍとを一対設け、雌側鉤部６１と雄側鉤部６２とを一対設けたが、本発明では、２対以上としてもよい。 For example, in each of the above embodiments, the male member M is configured by integrally providing a pair of male claw portions 222 at the tip of the protruding portion 520. However, in the present invention, the male member M is divided along the width direction. It is good also as a structure.
