Description

【0001】
【発明の属する技術分野】
本発明は、螺合停止位置を越えてオーバーランしてしまうことを確実に防止することができるとともに、キャップ体の外形寸法も小さく維持することができる構造簡単な位置決め容器に関する。
【0002】
【従来の技術】
従来より、容器本体をこれに螺合したキャップ体で封止する容器のうち、容器に正面や裏面があってキャップ体の向きがこれに合致するよう、容器本体を封止した際の当該容器本体に対するキャップ体の螺合停止位置を一定位置とすることができる位置決め機構を備えた位置決め容器が知られている。
【0003】
例えば、瓶首の外周壁から***させて形成した凸ネジ条に、瓶蓋の内周壁から***させて形成したリブを係合させるようにし、そして特に、瓶蓋をねじ込むことでリブが凸ネジ条に係合し始める当該凸ネジ条の始端部とは反対側の、リブが凸ネジ条と最も深く係合するその終端部に、返り止め突起と停止突起とを瓶蓋のねじ込み方向に順次に形成しておき、瓶蓋をねじ込んでいくことで返り止め突起を乗り越えたリブを停止突起に突き当てることにより瓶蓋のそれ以上のねじ込みを阻止して、これによって瓶首に対する瓶蓋の停止位置を位置決めするようにしたものが知られている(実開昭49−43370号公報)。
【0004】
【発明が解決しようとする課題】
ところで、上記従来の位置決め容器にあっては、凸ネジ条の終端部のみに形成した停止突起とリブとの一箇所のみの突き当てによって位置決めするようにしていたため、位置決めに関わる停止突起とリブとの突き当て面積は狭いものであり、リブが停止突起を乗り越えてオーバーランしてしまうおそれがあった。特に、瓶蓋が可撓変形する合成樹脂材である場合や、また瓶首と瓶蓋がともにガラス製あるいは硬質樹脂製である場合も、その可能性が大きかった。このようなおそれを考慮して突き当て面積を広く確保すべく、凸ネジ条を複数条形成するとともにリブも複数形成すると、そのためにこれら瓶首や瓶蓋を成型するための金型等の成形型のコストアップを招いてしまうという問題もあった。
【0005】
また、凸ネジ条に係合しつつ停止突起に突き当てられるリブは、瓶蓋の内周壁から***させて形成されていて、このため瓶蓋の外形寸法が必要的に大きくなってしまうという問題もあった。
【0006】
本発明はかかる従来の課題に鑑みてなされたもので、螺合停止位置を越えてオーバーランしてしまうことを確実に防止することができるとともに、キャップ体の外形寸法も小さく維持することができる構造簡単な位置決め容器を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明にかかる位置決め容器は、容器本体を封止するためにこれに螺合されるキャップ体の当該容器本体に対する螺合停止位置を位置決めするようにした位置決め容器において、上記容器本体の外周壁から***させて、一条の凸ネジ条を一回り形成し、上記キャップ体の内周壁を窪ませて上記凸ネジ条に螺合する一条の凹ネジ条を、該凸ネジ条と同一長さで一回り形成し、上記両ネジ条が螺合を開始する各ネジ条の始端部とは反対側の各終端部のうち、上記凸ネジ条の終端部には、上記凹ネジ条始端部の上記キャップ体内周壁を係止して該凹ネジ条の螺合移動を制止する容器本体側制止部を、上記容器本体外周壁から凸ネジ条相当で***させて形成するとともに、上記凹ネジ条の終端部には、上記凸ネジ条始端部を係止して該凸ネジ条の螺合移動を制止するキャップ体側制止部を、上記キャップ体内周壁で該凹ネジ条を封鎖して形成し、これら凹ネジ条の始端部および凸ネジ条の始端部それぞれが、上記容器本体側制止部および上記キャップ体側制止部双方に同時に係止されることにより、上記容器本体に対する上記キャップ体の螺合停止位置を位置決めするようにしたことを特徴とする。
【0008】
また、前記容器本体と前記キャップ体との間に、前記一対の制止部によって該キャップ体が該容器本体に位置決めされる直前の位置で係脱自在に係合して該キャップ体が位置決めされることを報知する係合部を設けたことを特徴とする。
【0009】
【発明の実施の形態】
以下に、本発明にかかる位置決め容器の好適な一実施形態を、添付図面を参照して詳細に説明する。本実施形態にあっては位置決め容器1として、ガラス製の容器本体2と、容器本体2を封止するためにこれに螺合される硬質合成樹脂製のキャップ体3とからなるクリーム容器が例示されている。
【0010】
図1に示すように容器本体2は、平面外形輪郭がほぼ正方形状に形成されて内容物が収容される有底中空筒体状の胴部4を備え、この胴部4の上には肩部5を介して、内容物を取り出すために上端が開口された中空円筒形状の首部6が上方に向かって突出形成されていて、この首部6は容器本体2の外周壁の一部をなしている。他方、キャップ体3は、平面外形輪郭が胴部4に合致するほぼ正方形状に形成されるとともに、その内部には、キャップ体3を円筒形状の首部6に装着可能とする凹部7を区画形成するために、図2に示すように首部6との間にわずかな隙間Sを隔てる内径寸法R1で円形の内周壁8が形成されている。またキャップ体3には、内周壁8よりも外側であって容器本体2を封止した際に肩部5に当接される下端部に、内周壁8の内径よりも大きな内径を有する口縁部9が形成されている。そしてキャップ体3と容器本体2との間には、容器本体2の外形輪郭と合致する位置でキャップ体3の螺合を停止させるために、以下に説明する位置決め機構が備えられる。
【0011】
首部6にはこれを周回して、一条の凸ネジ条10が一回り形成される。この凸ネジ条10は、首部6にキャップ体3を装着できるようにその口縁部9の内径よりも小さな外径寸法であって、かつ上記隙間Sの寸法よりも大きな寸法で、首部6から外方へ***させて形成される。すなわち、凸ネジ条10は、内周壁8の内径R1よりも大きな「外径R2」のネジ条として形成される。他方、キャップ体3の内周壁8にもこれを周回して、凸ネジ条10と同一長さで当該凸ネジ条10と螺合し合う一条の凹ネジ条11が一回り形成される。この凹ネジ条11は内周壁8を窪ませることにより、当該内周壁8の内径R1よりも大きな「外径R2」を有する凸ネジ条10に対応した「谷の径R3」を有するネジ条として形成され、その一端は口縁部9に達して当該口縁部9と連通されている。そして、口縁部9側からキャップ体3を首部6に被せて凸ネジ条10に対し凹ネジ条11を螺合することによりキャップ体3を首部6にねじ込むことができ、これによって容器本体2を封止することができる。
【0012】
特に、これら凸ネジ条10と凹ネジ条11が互いに螺合を開始する各ネジ条10,11の始端部10a,11aとは反対側の凸ネジ条10および凹ネジ条11それぞれの終端部10b,11bに関し、まず凸ネジ条10について説明すると、凸ネジ条10の終端部10bには、凹ネジ条11の螺合移動を制止するための容器本体側制止部として凸部12が形成される。この凸部12は本実施形態にあっては、凸ネジ条10の下側に、当該凸ネジ条10と同程度の高さで首部6から***させて形成されている。そしてこの凸部12は、少なくとも凸ネジ条10の形成方向に対して、すなわちキャップ体3のねじ込み方向に対して首部6から突出した段差となっている。図示例にあっては、凸部12は凸ネジ条10と一連に一体的に形成されているけれども、凸ネジ条10とは分離して独立に形成してもよいことはもちろんである。
【0013】
そして首部6に装着したキャップ体3を凸ネジ条10と凹ネジ条11の螺合に従ってねじ込んでいくと、凸ネジ条10の「外径R2」よりも大きな内径の口縁部9が凸部12を越えて肩部5に向かって接近していき、その後、図3に示すように凸ネジ条10の終端部10bに凹ネジ条11の始端部11aが達すると、凸部12の首部6からの***高さ寸法が上記隙間Sの寸法よりも大きいために、凹ネジ条11の始端部11a近傍の内周壁8が、段差となっている当該凸部12に突き当たって係止されることになり、これにより凹ネジ条11のそれ以上の螺合移動が制止される。
【0014】
他方、凹ネジ条11について説明すると、凹ネジ条11の終端部11bには、凸ネジ条10の螺合移動を制止するためのキャップ体側制止部として封鎖部13が形成されている。この封鎖部13は本実施形態にあっては、内周壁8を窪ませて形成した凹ネジ条11の終端を当該内周壁8で埋めることにより封鎖して形成されている。そしてこの封鎖部13は、少なくとも凹ネジ条11の形成方向に対して、すなわちキャップ体3のねじ込み方向に対して凹ネジ条11から突出した段差となっている。図示例にあっては、封鎖部13は内周壁8の壁面に連続して形成されているけれども、内周壁8の壁面と連続する形態でなくてもよいことはもちろんである。そして首部6に装着したキャップ体3をねじ込んでいくことによって凹ネジ条11の終端部11bに達した凸ネジ条10の始端部10aは図3に示すように、段差となっている封鎖部13に突き当たって係止されることになり、これにより凸ネジ条10のそれ以上の螺合移動が制止される。
【0015】
そしてこれら凸ネジ条10と凹ネジ条11とが同じ長さで形成されていることから、容器本体2とキャップ体3との外形輪郭が合致するキャップ体3の螺合停止位置において、これら両ネジ条10,11の始端部10a,11aそれぞれが凸部12および封鎖部13双方に同時に係止され、これらによって容器本体2に対するキャップ体3の螺合停止位置が位置決めされる。このように各ネジ条10,11に対応させて凸部12や封鎖部13を備えるという簡単な構成によって、キャップ体3の螺合停止位置を位置決めする際の突き当て面積を大きく広く確保することができる。したがって、キャップ体3のオーバーランを確実に防止することができる。特に、一条ネジであっても十分な突き当て面積を得ることができることから、ネジ条を複数形成する場合に比べて成形型のコストダウンを達成しつつ、キャップ体3を確実に位置決めできる。
【0016】
また、容器本体側制止部である凸部12は凸ネジ条10相当で***させたものであり、またキャップ体側制止部である封鎖部13はキャップ体3の内周壁8で凹ネジ条11を封鎖させたものであって、図2に示すようにキャップ体内周壁8と首部6との隙間Sを増大させることなく、これらネジ条10,11の形成範囲であるR1〜R2内に位置決め機構を備えることができ、位置決め機構のためにキャップ体3の外形寸法が大きくなることを防止することができる。
【0017】
さらに、容器本体2とキャップ体3との間には、キャップ体3が容器本体2に位置決めされる直前の位置で係脱自在に係合してキャップ体3が位置決めされることを音や感触で報知する係合部が設けられる。本実施形態にあっては、容器本体2には、凸部12直下および首部6周りの反対側位置に、肩部5から首部6にわたる隅部に上方へ向かって突出させて一対の係合突起14が形成されるとともに、キャップ体3には、凹ネジ条11よりも下方の口縁部9であってかつ凹ネジ条11の始端部11aよりキャップ体3のねじ込み方向前方および内周壁8周りの反対側位置に、凹部7側に突出させて一対の乗り上げ突起15が形成される。
【0018】
そして、首部6の上下方向に沿う凸ネジ条10と凹ネジ条11との間のギャップGを利用して、乗り上げ突起15がその下端から係合突起14の上端を乗り上げて互いに係合するようになっていて、これにより容器本体2およびキャップ体3がガラス製や硬質合成樹脂製などの硬質な素材であって首部6や内周壁8がそれらの径方向に変形することを期待できないものであっても、良好な係脱作用を確保することができる。
【0019】
そしてこの乗り上げ突起15が係合突起14に係合する際の感触や音によって、キャップ体3が容器本体2に位置決めされることが報知されるようになっている。これにより、キャップ体3の過度のねじ込みを防止することができる。またこの係合部は、その係合によってキャップ体3を位置決め位置に保持するとともに、キャップ体3を緩める方向に回すことによって係合が外されるようになっている。
【0020】
以上説明した本実施形態にあっては、ガラス製の容器本体2と硬質合成樹脂製のキャップ体3を例示して説明したが、これらはともにガラス製であっても、また硬質・軟質の合成樹脂製であってもよいことはもちろんである。
【0021】
【発明の効果】
以上要するに、本発明にかかる位置決め容器にあっては、凹ネジ条や凸ネジ条に対応させて、容器本体側制止部やキャップ体側制止部を備えるという簡単な構成によって、キャップ体の螺合停止位置を位置決めする際の突き当て面積を大きく広く確保して、キャップ体が螺合停止位置を越えてオーバーランしてしまうことを確実に防止することができる。特に、一条ネジであっても十分な突き当て面積を得ることができることから、成形型のコストダウンを達成しつつ、キャップ体を確実に位置決めできる。凸ネジ条相当で***されまた凹ネジ条を封鎖して形成した制止部であることから、キャップ体の外形寸法も小さく維持することができる。
【0022】
また、キャップ体が位置決めされることを報知する係合部によって、キャップ体の過度のねじ込みを防止することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a positioning container with a simple structure that can reliably prevent overrun beyond a screwing stop position and can keep the outer dimension of a cap body small.
[0002]
[Prior art]
Conventionally, among containers that are sealed with a cap body screwed into the container body, the container body when the container body is sealed so that the container has a front surface and a back surface and the direction of the cap body matches this. 2. Description of the Related Art A positioning container having a positioning mechanism capable of setting a screwing stop position of a cap body with respect to a main body to a constant position is known.
[0003]
For example, a rib formed by protruding from the inner peripheral wall of the bottle lid is engaged with a convex thread formed by protruding from the outer peripheral wall of the bottle neck, and in particular, the rib is protruded by screwing the bottle lid. At the terminal end of the rib opposite to the starting end of the convex thread that starts to engage with the strip, the detent and stop projection are sequentially placed in the screwing direction of the bottle lid. By screwing the bottle lid, the rib that has overcome the detent protrusion is abutted against the stop protrusion to prevent further screwing of the bottle lid, thereby stopping the bottle lid against the bottle neck. A device in which the position is determined is known (Japanese Utility Model Publication No. 49-43370).
[0004]
[Problems to be solved by the invention]
By the way, in the conventional positioning container, since the positioning is performed by abutting the stop protrusion and the rib formed only on the terminal end portion of the convex thread, only the stop protrusion and the rib related to the positioning are arranged. Since the abutting area of the rib is small, there is a possibility that the rib may overrun the stop protrusion and overrun. In particular, when the bottle lid is made of a synthetic resin material that is flexibly deformed, and when both the bottle neck and the bottle lid are made of glass or hard resin, the possibility is high. In consideration of such fears, in order to secure a wide abutting area, when a plurality of convex screw threads are formed and a plurality of ribs are formed, a mold for molding these bottle necks and bottle lids is formed for that purpose. There was also a problem that the cost of the mold was increased.
[0005]
Further, the rib that is abutted against the stop protrusion while engaging with the convex thread is formed so as to be raised from the inner peripheral wall of the bottle lid, so that the outer dimension of the bottle lid becomes necessary and large. There was also.
[0006]
The present invention has been made in view of such conventional problems, and can reliably prevent overrun beyond the screwing stop position and can also keep the outer dimension of the cap body small. An object is to provide a positioning container having a simple structure.
[0007]
[Means for Solving the Problems]
A positioning container according to the present invention is a positioning container that positions a screwing stop position with respect to a container body of a cap body screwed to the container body in order to seal the container body, from the outer peripheral wall of the container body. A single convex screw strip is formed to form a single loop, and the inner circumferential wall of the cap body is recessed to be screwed into the convex screw strip. Of the end portions on the opposite side to the start end portions of the respective screw threads that are formed to rotate, the caps of the concave screw start end portions are included in the end portions of the convex screw threads. A container body-side restraining portion that locks the body peripheral wall and restrains the screwed movement of the concave screw strip is formed by protruding from the outer peripheral wall of the container main body in a manner equivalent to a convex screw strip, and the terminal portion of the concave screw strip The above-mentioned convex screw thread is engaged by locking the convex thread starting end. The cap-side restraining portion for restraining the movement, is formed by blocking the concave screw protrusion in the cap body wall, each beginning of beginning and convex threads of these concave screws Article, the container main body side restraint and It is characterized in that the screwing stop position of the cap body with respect to the container body is positioned by being simultaneously locked to both the cap body side restraining portions .
[0008]
Further, the cap body is positioned between the container body and the cap body by the pair of restraining portions so that the cap body is detachably engaged at a position immediately before the container body is positioned on the container body. It is characterized in that an engaging portion for informing this is provided.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of a positioning container according to the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, the positioning container 1 is exemplified by a cream container comprising a glass container body 2 and a hard synthetic resin cap body 3 screwed into the container body 2 to seal the container body 2. Has been.
[0010]
As shown in FIG. 1, the container main body 2 has a bottomed hollow cylindrical body 4 having a planar outer contour formed in a substantially square shape and containing contents, and a shoulder 4 is placed on the body 4. A hollow cylindrical neck portion 6 whose upper end is opened to take out the contents through the portion 5 is formed to protrude upward, and this neck portion 6 forms a part of the outer peripheral wall of the container body 2. Yes. On the other hand, the cap body 3 is formed in a substantially square shape whose planar outer contour matches the body portion 4, and a concave portion 7 is formed in the cap body 3 so that the cap body 3 can be attached to the cylindrical neck portion 6. For this purpose, as shown in FIG. 2, a circular inner peripheral wall 8 is formed with an inner diameter R <b> 1 separating a slight gap S from the neck 6. Further, the cap body 3 is provided with a lip having an inner diameter larger than the inner diameter of the inner peripheral wall 8 at the lower end portion which is outside the inner peripheral wall 8 and is in contact with the shoulder portion 5 when the container body 2 is sealed. Part 9 is formed. A positioning mechanism described below is provided between the cap body 3 and the container body 2 in order to stop screwing of the cap body 3 at a position that matches the outline of the container body 2.
[0011]
The neck 6 orbiting this convex thread Article 10 Article is formed one size. The convex thread 10 has an outer diameter smaller than the inner diameter of the lip 9 and larger than the gap S so that the cap body 3 can be attached to the neck 6. It is formed to protrude outward. That is, the convex thread 10 is formed as a thread having an “outer diameter R2” larger than the inner diameter R1 of the inner peripheral wall 8. On the other hand, also the inner circumferential wall 8 of the cap body 3 circling this, concave threads of 11 Ichijo threadably engaging with the convex screw strip 10 is formed slightly convex threads of 10 and the same length. The concave thread 11 is formed as a thread having a “valley diameter R3” corresponding to the convex thread 10 having an “outer diameter R2” larger than the inner diameter R1 of the inner peripheral wall 8 by recessing the inner peripheral wall 8. One end thereof reaches the rim 9 and communicates with the lip 9. And the cap body 3 can be screwed into the neck part 6 by covering the cap body 3 on the neck part 6 from the mouth edge part 9 side and screwing the concave thread 11 to the convex thread 10, thereby the container body 2 Can be sealed.
[0012]
In particular, the convex screw 10 and the concave screw 11 on the opposite sides of the convex screw 10 and the concave screw 11 on the opposite side to the starting ends 10a, 11a of the screw 10, 10 where the convex screw 10 and the concave screw 11 start to be engaged with each other. , 11b, the convex thread 10 will be described first. A convex part 12 is formed on the terminal part 10b of the convex thread 10 as a container body side restraining part for restraining the screwed movement of the concave thread 11. . In the present embodiment, the convex portion 12 is formed on the lower side of the convex screw strip 10 so as to protrude from the neck portion 6 at the same height as the convex screw strip 10. And this convex part 12 is the level | step difference which protruded from the neck part 6 with respect to the formation direction of the convex thread 10 at least, ie, the screwing direction of the cap body 3. FIG. In the example of illustration, although the convex part 12 is integrally formed with the convex screw strip 10 in series, it is needless to say that it may be formed separately from the convex screw strip 10.
[0013]
When the cap body 3 attached to the neck 6 is screwed in according to the screwing of the convex screw 10 and the concave screw 11, the lip 9 having an inner diameter larger than the “outer diameter R2” of the convex screw 10 is the convex. 12, approaching the shoulder 5, and then, when the start end 11 a of the concave thread 11 reaches the terminal end 10 b of the convex thread 10 as shown in FIG. 3, the neck 6 of the convex 12 Since the height of the raised portion is larger than the size of the gap S, the inner peripheral wall 8 in the vicinity of the start end portion 11a of the concave thread 11 abuts against the convex portion 12 that is a step and is locked. Thus, further screwing movement of the concave thread 11 is restrained.
[0014]
On the other hand, the concave thread 11 will be described. The end portion 11b of the concave thread 11 is formed with a blocking part 13 as a cap body side restraining part for restraining the screwing movement of the convex thread 10. In the present embodiment, the blocking portion 13 is formed by sealing the end of the concave thread 11 formed by recessing the inner peripheral wall 8 with the inner peripheral wall 8. And this blockade part 13 is the level | step difference which protruded from the concave thread 11 with respect to the formation direction of the concave thread 11, ie, the screwing direction of the cap body 3 at least. In the illustrated example, the blocking portion 13 is continuously formed on the wall surface of the inner peripheral wall 8, but it is needless to say that the block portion 13 does not have to be continuous with the wall surface of the inner peripheral wall 8. Then, by screwing the cap body 3 attached to the neck portion 6, the start end portion 10 a of the convex screw thread 10 reaching the terminal end portion 11 b of the concave screw thread 11 has a stepped sealing portion 13 as shown in FIG. 3. The protruding screw 10 is stopped by further screwing movement.
[0015]
Since the convex screw strip 10 and the concave screw strip 11 are formed with the same length, both the cap body 3 and the cap body 3 are matched at the screwing stop position where the outer contours of the container body 2 and the cap body 3 match. The start end portions 10a and 11a of the screw strips 10 and 11 are simultaneously locked to both the convex portion 12 and the sealing portion 13, respectively, thereby positioning the screwing stop position of the cap body 3 with respect to the container body 2. In this way, by providing a simple configuration in which the convex portions 12 and the blocking portions 13 are provided corresponding to the respective screw strips 10 and 11, a large and wide abutting area when positioning the screwing stop position of the cap body 3 is secured. Can do. Therefore, the overrun of the cap body 3 can be reliably prevented. In particular, since a sufficient abutting area can be obtained even with a single thread, the cap body 3 can be reliably positioned while achieving a reduction in the cost of the mold compared to the case where a plurality of threads are formed.
[0016]
Further, the convex portion 12 that is the container main body side restraining portion is raised by an equivalent to the convex screw strip 10, and the sealing portion 13 that is the cap body side restraining portion is formed by the inner peripheral wall 8 of the cap body 3 with the concave screw strip 11. As shown in FIG. 2, a positioning mechanism is provided in R <b> 1 to R <b> 2 where the thread strips 10 and 11 are formed without increasing the gap S between the cap body peripheral wall 8 and the neck portion 6 as shown in FIG. 2. It can be provided, and it can prevent that the external dimension of the cap body 3 becomes large for a positioning mechanism.
[0017]
Furthermore, between the container main body 2 and the cap body 3, it is sound and feel that the cap body 3 is positioned by releasably engaging the cap body 3 at a position immediately before the container main body 2 is positioned. An engaging portion for informing is provided. In the present embodiment, the container body 2 has a pair of engaging protrusions that are projected directly upward from the shoulder 5 to the corner extending from the neck 6 at a position directly below the convex portion 12 and around the neck 6. 14 is formed, and the cap body 3 has a lip 9 below the concave thread 11 and a front end portion 11a of the concave thread 11 in the screwing direction of the cap body 3 and around the inner peripheral wall 8. A pair of climbing protrusions 15 are formed at the opposite side position so as to protrude toward the concave portion 7.
[0018]
Then, using the gap G between the convex thread 10 and the concave thread 11 along the vertical direction of the neck 6, the riding protrusion 15 rides on the upper end of the engaging protrusion 14 from the lower end so as to engage with each other. As a result, the container body 2 and the cap body 3 are made of a hard material such as glass or hard synthetic resin, and the neck 6 and the inner peripheral wall 8 cannot be expected to be deformed in the radial direction. Even if it exists, a favorable engagement / disengagement operation can be ensured.
[0019]
Then, it is notified that the cap body 3 is positioned on the container body 2 by the feeling and sound when the riding protrusion 15 is engaged with the engaging protrusion 14. Thereby, the excessive screwing of the cap body 3 can be prevented. The engaging portion holds the cap body 3 in the positioning position by the engagement, and the engagement is released by turning the cap body 3 in the loosening direction.
[0020]
In the present embodiment described above, the glass container main body 2 and the hard synthetic resin cap body 3 are described as examples. However, both of these are made of glass, and the hard / soft synthetic material is used. Of course, it may be made of resin.
[0021]
【The invention's effect】
In short, in the positioning container according to the present invention, the screw stop of the cap body is provided by a simple configuration including a container main body side restraining portion and a cap body side restraining portion corresponding to the concave screw thread and the convex screw thread. It is possible to ensure a large and wide abutting area when positioning the position and reliably prevent the cap body from overrunning beyond the screwing stop position . In particular, since a sufficient abutting area can be obtained even with a single thread, the cap body can be reliably positioned while achieving cost reduction of the mold. Since it is a restraining portion that is raised by being equivalent to the convex thread and is formed by blocking the concave thread, the outer dimension of the cap body can be kept small.
[0022]
In addition, the cap body can be prevented from being excessively screwed by the engaging portion that informs that the cap body is positioned.
