Description

本発明は、計量容器に関するものである。   The present invention relates to a weighing container.

従来から、例えば下記特許文献１に示されるような、扁平な錠剤が多数積み重ねられて収容される有底筒状の内筒体と、内筒体に外装される外筒体と、を備え、内筒体における底部側の下端部に、側方に向けて開口する取り出し孔が形成され、外筒体が内筒体に対して上下動することで、取り出し孔が開閉される容器が知られている。
そして、取り出し孔を開放した状態で、容器を、取り出し孔が下方を向くように傾けたときに、内筒体内の多数の錠剤のうち、内筒体の底部上に位置する最下端の錠剤が、取り出し孔から外側に移動させられる。この際、最下端の錠剤には、その上に積み重ねられた他の錠剤の荷重によって、内筒体の底部上に向けた押し付け力が加えられているため、最下端の錠剤は底部上で摺動しにくくなっており、錠剤の取り出し孔からの飛び出しが抑えられている。 Conventionally, for example, as shown in Patent Document 1 below, a bottomed cylindrical inner cylinder in which a number of flat tablets are stacked and accommodated, and an outer cylinder that is externally mounted on the inner cylinder, A container is known in which a take-out hole that opens toward the side is formed in the lower end portion on the bottom side of the inner cylinder, and the take-out hole is opened and closed as the outer cylinder moves up and down with respect to the inner cylinder. ing.
Then, when the container is tilted with the take-out hole open, the bottommost tablet located on the bottom of the inner cylinder is among the many tablets in the inner cylinder. , Moved outward from the take-out hole. At this time, the tablet at the bottom end is slid on the bottom because a pressing force is applied to the bottom of the inner cylinder by the load of the other tablets stacked on the tablet at the bottom. It is hard to move, and the pop-out from the tablet take-out hole is suppressed.

特開２０１０−２３５１９４号公報JP 2010-235194 A

しかしながら、前記従来の容器では、内筒体内の錠剤の数が残り少なくなったときに、前述の押し付け力が低くなり、例えば取り出し孔から錠剤が勢いよく飛び出したり、複数の錠剤が取り出し孔から立て続けに飛び出したりする等のおそれがあった。   However, in the conventional container, when the number of tablets in the inner cylinder becomes small, the above-mentioned pressing force decreases, for example, the tablets pop out vigorously from the takeout hole, or a plurality of tablets keep standing from the takeout hole. There was a risk of jumping out.

本発明は、このような事情を考慮してなされたもので、内容物の残量にかかわらず、規定量の内容物を精度よく取り出すことができる計量容器を提供することを目的とする。   The present invention has been made in view of such circumstances, and an object of the present invention is to provide a measuring container capable of accurately taking out a specified amount of contents regardless of the remaining amount of contents.

上記課題を解決して、このような目的を達成するために、本発明の計量容器は、内容物が収容される収容部を有するとともに、上方付勢状態で下方移動可能に支持された内筒体と、前記内筒体の上端部を上方に突出させた状態でこの内筒体に外装された外筒体と、これらの両筒体の各下端開口を閉塞する底体と、を備える計量容器であって、前記外筒体の内周面、及び前記内筒体の外周面には、前記内筒体を前記外筒体に対して押下したときに、前記内筒体を、前記外筒体に対して容器軸回りに回転させながら下降させる案内部が形成され、前記内筒体には、規定量の内容物が収容される計量部が形成され、前記外筒体には、前記計量部内の内容物が取り出される取り出し孔が形成され、前記底体には、前記内筒体の下降移動に伴い前記収容部内に進出する進出突起が備えられ、前記進出突起には、前記収容部の内容物を前記計量部に導く導入部が形成され、前記内筒体は、この内筒体の前記外筒体に対する押下及びその解除に伴い、前記計量部と前記導入部とが連通し、かつ前記計量部と前記取り出し孔との連通が遮断された計量位置と、前記計量部と前記取り出し孔とが連通し、かつ前記計量部と前記導入部との連通が遮断された取り出し位置と、の間を移動するように配設されていることを特徴とする。   In order to solve the above-mentioned problems and achieve such an object, the measuring container of the present invention has an accommodating portion in which the contents are accommodated and is supported so as to be movable downward in an upwardly biased state. And a bottom body that closes the lower end openings of both cylinders, and an outer cylinder that is externally covered with the inner cylinder with the upper end of the inner cylinder protruding upward. A container, the inner cylindrical surface of the outer cylindrical body, and the outer peripheral surface of the inner cylindrical body when the inner cylindrical body is pressed against the outer cylindrical body, A guide part that is lowered while rotating around the container axis with respect to the cylinder is formed, a measuring part that accommodates a predetermined amount of contents is formed in the inner cylinder, and the outer cylinder has the above-mentioned A take-out hole for taking out the contents in the measuring section is formed, and the housing is accommodated in the bottom body as the inner cylinder moves downward. An advancing protrusion that extends into the inside is provided, and the advancing protrusion is formed with an introduction portion that guides the contents of the housing portion to the measuring portion, and the inner cylinder body is connected to the outer cylinder body. With the pressing and release thereof, the measuring portion and the introducing portion communicate with each other, and the measuring position where communication between the measuring portion and the take-out hole is blocked, and the measuring portion and the take-out hole communicate with each other, And it is arrange | positioned so that it may move between the taking-out position from which the communication of the said measurement part and the said introduction part was interrupted | blocked.

この発明によれば、内筒体が前記取り出し位置に位置しているときに、計量部と取り出し孔とが連通し、かつ計量部と導入部との連通が遮断されているので、収容部内の内容物が、不意に取り出し孔に達することがなく、計量部内の内容物だけを取り出し孔から取り出すことができる。
一方、内筒体が前記計量位置に位置しているときには、計量部と導入部とが連通し、かつ計量部と取り出し孔との連通が遮断されているので、収容部内の内容物が、不意に取り出し孔に達するのを防ぎつつ、収容部内の内容物のうち、規定量の内容物だけを計量部に収容することができる。
以上より、収容部内での内容物の残量にかかわらず、規定量の内容物を精度よく取り出すことができる。
また、内筒体を、前記計量位置と前記取り出し位置との間で移動させるときに、内筒体を外筒体に対して一方向に移動させるだけでなく、内筒体を、外筒体に対して容器軸回りに回転させながら下降させるので、収容部内の内容物が、進出突起の外周面との間に挟み込まれるのを抑えることができる。
また、進出突起に導入部が形成されているので、収容部内の内容物を、導入部内で例えば整列させた状態で計量部に供給すること等が可能になり、計量部に内容物を容易かつ確実に収容することができる。 According to the present invention, when the inner cylinder is located at the take-out position, the measuring portion and the take-out hole communicate with each other, and the communication between the measure- ment portion and the introducing portion is blocked.

ここで、進出突起２５の外周面には、内側に向けて窪むとともに、内筒体１２が計量位置と取り出し位置との間を移動するのに伴って、張出部１６を移動させる逃げ面部３１が形成されている。
逃げ面部３１は、進出突起２５における容器軸Ｏ方向の全長にわたって形成されている。逃げ面部３１のうち、図１及び図２に示されるように、計量位置に位置する内筒体１２の計量部１５が開口する計量部分３１ａに、導入部２８が開口している。逃げ面部３１のうち、前記回転方向の前側Ｔ１の端部には、図２及び図４に示されるように、前記回転方向の後側Ｔ２を向く周端面部３１ｃが形成されている。内筒体１２が計量位置に位置しているときには、逃げ面部３１の周端面部３１ｃと、張出部１６の周端面部１６ａと、の間に周方向の隙間が設けられ、内筒体１２が取り出し位置に位置したときに、張出部１６の周端面部１６ａが、逃げ面部３１の周端面部３１ｃに当接する。 Here, the outer peripheral surface of the advancing protrusion 25 is recessed toward the inside, and the flank portion 31 that moves the projecting portion 16 as the inner cylinder 12 moves between the measurement position and the take-out position. Is formed.
The flank portion 31 is formed over the entire length of the advancing protrusion 25 in the container axis O direction. As shown in FIGS. 1 and 2, in the flank 31, the introduction portion 28 is opened in a measuring portion 31 a where the measuring portion 15 of the inner cylinder 12 located at the measuring position is opened. As shown in FIGS. 2 and 4, a circumferential end surface portion 31 c facing the rear side T <b> 2 in the rotation direction is formed at the end portion of the flank surface portion 31 on the front side T <b> 1 in the rotation direction. When the inner cylindrical body 12 is located at the measuring position, a circumferential clearance is provided between the peripheral end surface portion 31c of the flank portion 31 and the peripheral end surface portion 16a of the overhanging portion 16, and the inner cylindrical body 12 Is positioned at the take-out position, the peripheral end surface portion 16 a of the overhang portion 16 abuts on the peripheral end surface portion 31 c of the flank portion 31.

進出突起２５の、容器軸Ｏに直交する横断面視において、逃げ面部３１の計量部分３１ａにおける曲率半径は、逃げ面部３１の非形成部分２５ａにおける曲率半径より大きくなっている。この計量容器１の、内筒体１２の下端部を含む前記横断面視において、張出部１６の曲率半径は、逃げ面部３１の計量部分３１ａにおける曲率半径と同等とされ、内筒体１２の内周面のうち張出部１６の非形成部分１２ａにおける曲率半径は、逃げ面部３１の非形成部分２５ａの曲率半径と同等になっている。   In a cross-sectional view of the advancing protrusion 25 perpendicular to the container axis O, the radius of curvature of the measuring portion 31a of the flank 31 is larger than the radius of curvature of the non-formed portion 25a of the flank 31. In the cross-sectional view including the lower end portion of the inner cylindrical body 12 of the measuring container 1, the radius of curvature of the overhanging portion 16 is equal to the radius of curvature of the measuring portion 31a of the flank portion 31, and the inner cylindrical body 12 Of the inner peripheral surface, the radius of curvature of the non-formed portion 12 a of the overhang portion 16 is equal to the radius of curvature of the non-formed portion 25 a of the flank portion 31.

以上説明したように、本実施形態による計量容器１によれば、内筒体１２が取り出し位置に位置しているときに、計量部１５と取り出し孔２３とが連通し、かつ計量部１５と導入部２８との連通が遮断されているので、収容部１１内の内容物Ｗが、不意に取り出し孔２３に達することがなく、計量部１５内の内容物Ｗだけを取り出し孔２３から取り出すことができる。
一方、内筒体１２が計量位置に位置しているときには、計量部１５と導入部２８とが連通し、かつ計量部１５と取り出し孔２３との連通が遮断されているので、収容部１１内の内容物Ｗが、不意に取り出し孔２３に達するのを防ぎつつ、収容部１１内の内容物Ｗのうち、規定量の内容物Ｗだけを計量部１５に収容することができる。
以上より、収容部１１内での内容物Ｗの残量にかかわらず、規定量の内容物Ｗを精度よく取り出すことができる。 As described above, according to the measuring container 1 according to the present embodiment, when the inner cylinder 12 is located at the take-out position, the measuring unit 15 and the take-out hole 23 communicate with each other, and the measuring unit 15 and the introduction are provided. Since the communication with the portion 28 is blocked, the content W in the storage portion 11 does not unexpectedly reach the take-out hole 23, and only the content W in the measuring portion 15 can be taken out from the take-out hole 23. it can.
On the other hand, when the inner cylinder 12 is positioned at the measuring position, the measuring unit 15 and the introducing unit 28 are in communication with each other, and the communication between the measuring unit 15 and the take-out hole 23 is blocked. It is possible to accommodate only a specified amount of the contents W in the weighing unit 15 among the contents W in the accommodation unit 11 while preventing the contents W from unexpectedly reaching the take-out hole 23.
As described above, the specified amount of the contents W can be accurately taken out regardless of the remaining amount of the contents W in the storage unit 11.

また、内筒体１２を、計量位置と取り出し位置との間で移動させるときに、内筒体１２を外筒体１３に対して一方向に移動させるだけでなく、内筒体１２を、外筒体１３に対して容器軸Ｏ回りに回転させながら下降させるので、収容部１１内の内容物Ｗが、進出突起２５の外周面との間に挟み込まれるのを抑えることができる。
また、進出突起２５に導入部２８が形成されているので、収容部１１内の内容物Ｗを、導入部２８内で整列させた状態で計量部１５に供給することが可能になり、計量部１５に内容物Ｗを容易かつ確実に収容することができる。 Further, when the inner cylinder 12 is moved between the weighing position and the take-out position, not only the inner cylinder 12 is moved in one direction with respect to the outer cylinder 13, but the inner cylinder 12 is Since it is lowered while rotating around the container axis O with respect to the cylindrical body 13, it is possible to prevent the contents W in the accommodating portion 11 from being sandwiched between the outer peripheral surface of the advancing protrusion 25.
Moreover, since the introduction part 28 is formed in the advancing protrusion 25, it becomes possible to supply the contents W in the storage part 11 to the weighing part 15 in an aligned state in the introduction part 28. The contents W can be easily and reliably accommodated in 15.

また、内筒体１２の上端部に、キャップ体１９が容器軸Ｏ回りに回転自在に嵌合されているので、キャップ体１９を内筒体１２とともに外筒体１３に対して押下し、内筒体１２を外筒体１３に対して容器軸Ｏ回りに回転させたときに、キャップ体１９が内筒体１２とともに外筒体１３に対して回転するのを抑制することが可能になり、キャップ体１９を押下した手指に、容器軸Ｏ回りの回転力が伝わるのを抑えることができる。
また、計量部１５の下面が、径方向の内側から外側に向かうに従い漸次下方に向けて延びているので、内筒体１２が取り出し位置に位置しているときに、計量部１５内の内容物Ｗを取り出し孔２３に向けて容易に移動させることができる。 Further, since the cap body 19 is fitted to the upper end portion of the inner cylinder body 12 so as to be rotatable around the container axis O, the cap body 19 is pressed down against the outer cylinder body 13 together with the inner cylinder body 12, When the cylindrical body 12 is rotated around the container axis O with respect to the outer cylindrical body 13, it is possible to suppress the cap body 19 from rotating with respect to the outer cylindrical body 13 together with the inner cylindrical body 12, It is possible to prevent the rotational force around the container axis O from being transmitted to the finger that has pressed the cap body 19.
Further, since the lower surface of the weighing unit 15 extends gradually downward from the inner side to the outer side in the radial direction, when the inner cylinder 12 is located at the take-out position, the contents in the weighing unit 15 W can be easily moved toward the take-out hole 23.
