以下、本考案を実施するための好適な実施の形態（以下、実施形態という）を説明する。図１は本考案に係る試料作製用漏斗１００及び押し棒１０２を概略的に示す図である。図１（ａ）は、試料作製用漏斗１００を俯瞰的に見た図であり、図１（ｂ）は、押し棒１０２を俯瞰的に見た図である。また、図２（ａ）は、試料作製用漏斗１００の断面を示す図であり、図２（ｂ）は、試料作製用漏斗１００を上側から見た図である。   Hereinafter, a preferred embodiment (hereinafter referred to as an embodiment) for carrying out the present invention will be described. FIG. 1 is a view schematically showing a sample preparation funnel 100 and a push rod 102 according to the present invention. FIG. 1A is a top view of the sample preparation funnel 100, and FIG. 1B is a top view of the push rod 102. 2A is a view showing a cross section of the sample preparation funnel 100, and FIG. 2B is a view of the sample preparation funnel 100 as viewed from above.

図１（ａ）及び図２（ａ）に示すように、試料作製用漏斗１００は、漏斗部と、支持脚部１１４と、を有し、蛍光Ｘ線分析用の粉末試料４００（後述）を試料容器３００（後述）に入れる器具である。漏斗部は、上側開口１０４と、下側開口１０６と、内側側面１０８と、差込口１１０と、外側側面１１２とを有する。   As shown in FIGS. 1 (a) and 2 (a), the sample preparation funnel 100 has a funnel portion and a support leg portion 114, and a powder sample 400 for fluorescent X-ray analysis (described later). This is an instrument to be placed in a sample container 300 (described later). The funnel portion has an upper opening 104, a lower opening 106, an inner side surface 108, an insertion port 110, and an outer side surface 112.

上側開口１０４は、漏斗部の上側に設けられた開口部である。具体的には、例えば、上側開口１０４は、漏斗部の上側に設けられた５０ｍｍの径の開口部である。   The upper opening 104 is an opening provided on the upper side of the funnel portion. Specifically, for example, the upper opening 104 is an opening having a diameter of 50 mm provided on the upper side of the funnel portion.

下側開口１０６は、上側開口１０４よりも開口面積の小さい開口部である。具体的には、例えば下側開口１０６は、漏斗部の下端に設けられた開口部である。また、下側開口１０６は、図２（ｂ）に示すように、上側開口１０４よりも開口面積の小さい２０ｍｍの径の開口部である。   The lower opening 106 is an opening having an opening area smaller than that of the upper opening 104. Specifically, for example, the lower opening 106 is an opening provided at the lower end of the funnel portion. Further, as shown in FIG. 2B, the lower opening 106 is an opening having a diameter of 20 mm, which has an opening area smaller than that of the upper opening 104.

内側側面１０８は、上側開口１０４から下側開口１０６に向かって傾斜した面である。具体的には、内側側面１０８は、上側開口１０４から下側開口１０６に向かって傾斜した面であって、漏斗部を水平な床（例えば、実験用の作業台）に置いた場合に、床に対して６０乃至６５度傾いた面である。蛍光Ｘ線分析用の粉末試料４００が内側側面１０８を滑らかに滑るように、内側側面１０８は最大高さ粗さが６．３μｍ以下であることが望ましい。   The inner side surface 108 is a surface inclined from the upper opening 104 toward the lower opening 106. Specifically, the inner side surface 108 is a surface inclined from the upper opening 104 toward the lower opening 106, and when the funnel portion is placed on a horizontal floor (for example, an experimental work bench), The surface is inclined by 60 to 65 degrees with respect to the angle. It is desirable that the maximum roughness of the inner side surface 108 is 6.3 μm or less so that the powder sample 400 for X-ray fluorescence slides smoothly on the inner side surface 108.

差込口１１０は、内側側面１０８の下端と下側開口１０６との間に設けられる。具体的には、例えば、差込口１１０は、内側側面１０８の下端から下側に向かって、円筒状に形成される。差込口１１０の下端は、下側開口１０６である。   The insertion port 110 is provided between the lower end of the inner side surface 108 and the lower opening 106. Specifically, for example, the insertion port 110 is formed in a cylindrical shape from the lower end of the inner side surface 108 toward the lower side. The lower end of the insertion port 110 is a lower opening 106.

下側開口１０６は、図３に示すように内部に配置される試料容器３００の上端よりも低い位置に配置され、試料容器３００の動きを規制する。具体的には、例えば、試料作製用漏斗１００の内部に配置された状態で、下側開口１０６は、床から２５ｍｍの位置に配置される。また、高さが３０ｍｍである試料容器３００は、試料作製用漏斗１００の内部に配置される。これにより、差込口１１０が試料容器３００の縁に干渉することによって、下側開口１０６は、試料容器３００の動きを規制する。   As shown in FIG. 3, the lower opening 106 is disposed at a position lower than the upper end of the sample container 300 disposed inside, and restricts the movement of the sample container 300. Specifically, for example, the lower opening 106 is disposed at a position 25 mm from the floor in a state of being disposed inside the sample preparation funnel 100. Further, the sample container 300 having a height of 30 mm is arranged inside the sample preparation funnel 100. As a result, the insertion opening 110 interferes with the edge of the sample container 300, whereby the lower opening 106 regulates the movement of the sample container 300.

外側側面１１２は、内側側面１０８の外側に、内側側面１０８と傾きが異なるように形成される。具体的には、外側側面１１２は、内側側面１０８の外側に、試料作製用漏斗１００が水平に置かれた状態で垂直に形成される。また、内側側面１０８と外側側面１１２の間は、充填された構造であることが望ましい。内側側面１０８と外側側面１１２の間が充填されていれば、スパチュラで叩かれた外側側面１１２の振動が、内側側面１０８に伝わり易くなる。これにより、内側側面１０８に粉末試料４００が付着していた場合、付着した試料を容易に試料容器３００に入れることができる。なお、外側側面１１２は、床に対して垂直でなくてもよい。   The outer side surface 112 is formed outside the inner side surface 108 so as to have a different inclination from the inner side surface 108. Specifically, the outer side surface 112 is formed vertically outside the inner side surface 108 with the sample preparation funnel 100 placed horizontally. Further, it is desirable that the space between the inner side surface 108 and the outer side surface 112 is a filled structure. If the space between the inner side surface 108 and the outer side surface 112 is filled, vibration of the outer side surface 112 hit with a spatula is easily transmitted to the inner side surface 108. Thereby, when the powder sample 400 has adhered to the inner side surface 108, the adhered sample can be easily put into the sample container 300. The outer side surface 112 may not be perpendicular to the floor.

支持脚部１１４は、漏斗部と一体化され、床と接触して自立する脚部である。具体的には、例えば、支持脚部１１４は、図２（ａ）に示すように、試料容器３００が入れられる領域の周囲を囲むように、円筒状に形成される。なお、支持脚部１１４の形状は円筒状でなくてもよい。また、図２（ａ）では、外側側面１１２が支持脚部１１４と連続的に形成される実施形態を記載しているが、外側側面１１２と支持脚部１１４の間に段差が設けられてもよい。   The support leg 114 is a leg that is integrated with the funnel and is self-supporting in contact with the floor. Specifically, for example, as shown in FIG. 2A, the support leg 114 is formed in a cylindrical shape so as to surround a region where the sample container 300 is placed. Note that the shape of the support leg 114 may not be cylindrical. FIG. 2A illustrates an embodiment in which the outer side surface 112 is formed continuously with the support leg 114, but a step may be provided between the outer side surface 112 and the support leg 114. Good.

試料作製用漏斗１００が床に載置された状態で、床から下側開口１０６までの高さより高い試料容器３００の縁に当接する平坦部１１１を、漏斗部の外側に有する構成とすることが望ましい。例えば図２に示すように、試料作製用漏斗１００は、差込口１１０の周囲に平坦部１１１を有する。当該構成によれば、仮に支持脚部１１４の下端から差込口１１０の上側端部までの高さよりも高い試料容器３００に対して試料作製用漏斗１００を被せたとしても、当該平坦部１１１と試料容器３００の上端が当接することによって、試料容器３００が転倒することを防止できる。   In a state where the sample preparation funnel 100 is placed on the floor, the flat portion 111 that abuts the edge of the sample container 300 that is higher than the height from the floor to the lower opening 106 is provided outside the funnel portion. desirable. For example, as shown in FIG. 2, the sample preparation funnel 100 has a flat portion 111 around the insertion port 110. According to this configuration, even if the sample preparation funnel 100 is placed on the sample container 300 that is higher than the height from the lower end of the support leg 114 to the upper end of the insertion port 110, the flat portion 111 and When the upper end of the sample container 300 contacts, the sample container 300 can be prevented from falling.

支持脚部１１４の側面には、例えば図３乃至５に示すように、内部に配置される試料容器３００の有無が確認できる側面開口１１５を有してもよい。これにより、試料容器３００を設置し忘れて粉末試料４００を投入してしまうことを防止できる。側面開口１１５は、孔であっても床と接する面まで切り欠いたものでもよい。また、側面開口１１５を複数設けてもよい。   For example, as shown in FIGS. 3 to 5, the side surface of the support leg 114 may have a side opening 115 that allows the presence or absence of the sample container 300 to be confirmed. As a result, it is possible to prevent the powder sample 400 from being thrown in forgetting to install the sample container 300. The side opening 115 may be a hole or a notch up to a surface in contact with the floor. Further, a plurality of side openings 115 may be provided.

押し棒１０２は、試料容器３００に入れられた試料を押し固める棒状の器具である。具体的には、図１（ｂ）に示すように、押し棒１０２は、下側端部の外径が差込口１１０の内径より小さいかまたは同じである円柱状の器具である。また、押し棒１０２は、試料作製用漏斗１００に保管された状態（詳細は後述）で、下側端部を床から離れた位置に保持する当接部１１６を有する。当接部１１６の下側は、外径が差込口１１０の内径より小さいかまたは同じに形成される。当接部１１６の上側は、当接部１１６の下側と同じ外径となるように形成されてもよいし、図１（ａ）に示すように、当接部１１６の下側よりも大きい外径となるように形成されてもよい。   The push rod 102 is a rod-like instrument that pushes and hardens the sample placed in the sample container 300. Specifically, as shown in FIG. 1 (b), the push rod 102 is a cylindrical instrument whose outer diameter at the lower end is smaller than or equal to the inner diameter of the insertion port 110. Further, the push rod 102 has a contact portion 116 that holds the lower end portion at a position away from the floor in a state stored in the sample preparation funnel 100 (details will be described later). The lower side of the contact portion 116 is formed with an outer diameter smaller than or equal to the inner diameter of the insertion port 110. The upper side of the contact part 116 may be formed to have the same outer diameter as the lower side of the contact part 116, and is larger than the lower side of the contact part 116 as shown in FIG. You may form so that it may become an outer diameter.

試料作製用漏斗１００および押し棒１０２は、樹脂で形成される。具体的には、例えば、試料作製用漏斗１００および押し棒１０２は、ポリエチレン、ポリプロピレン、ポリオキシメチレンまたはポリテトラフルオロエチレンで形成される。これらの材質は化学的に不活性であり、粉末試料４００との接触による内側側面１０８および押し棒１０２の変質が起こりにくい。また、内側側面１０８および押し棒１０２の表面を滑らかに加工しやすいため、粉末試料４００を付着しにくくすることができる。   The sample preparation funnel 100 and the push rod 102 are made of resin. Specifically, for example, the sample preparation funnel 100 and the push rod 102 are formed of polyethylene, polypropylene, polyoxymethylene, or polytetrafluoroethylene. These materials are chemically inert, and the inner side surface 108 and the push rod 102 are not easily altered by contact with the powder sample 400. Moreover, since the inner side surface 108 and the surface of the push rod 102 are easily processed smoothly, the powder sample 400 can be made difficult to adhere.

試料作製用漏斗１００および押し棒１０２は、帯電防止剤を含む樹脂で形成されることが望ましい。これにより、内側側面１０８および押し棒１０２に、粉末試料４００を付着しにくくすることができる。   The sample preparation funnel 100 and the push rod 102 are preferably formed of a resin containing an antistatic agent. Thereby, the powder sample 400 can be made difficult to adhere to the inner side surface 108 and the push rod 102.

試料作製用漏斗１００は、内部に試料容器３００を収容できる大きさの空間を有する。具体的には、試料作製用漏斗１００は、支持脚部１１４の内径が試料容器３００の外径よりも大きくなるように形成される。例えば、試料容器３００の外径が４０ｍｍであれば、試料作製用漏斗１００は、支持脚部１１４の内径が４５ｍｍとなるように形成される。   The sample preparation funnel 100 has a space large enough to accommodate the sample container 300 therein. Specifically, the sample preparation funnel 100 is formed such that the inner diameter of the support leg 114 is larger than the outer diameter of the sample container 300. For example, if the outer diameter of the sample container 300 is 40 mm, the sample preparation funnel 100 is formed such that the inner diameter of the support leg 114 is 45 mm.

また、試料作製用漏斗１００は、差込口１１０の外径が試料容器３００の内径よりも小さくなるように形成される。例えば、試料容器３００の内径が２５ｍｍであれば、試料作製用漏斗１００は、差込口１１０の外径が２２ｍｍとなるように形成される。   The sample preparation funnel 100 is formed such that the outer diameter of the insertion port 110 is smaller than the inner diameter of the sample container 300. For example, if the inner diameter of the sample container 300 is 25 mm, the sample preparation funnel 100 is formed so that the outer diameter of the insertion port 110 is 22 mm.

また、試料作製用漏斗１００は、試料容器３００の上端が差込口１１０の上側端部の位置よりも低くなるように形成される。例えば、試料容器３００の高さが３０ｍｍである場合、試料作製用漏斗１００が床に置かれた状態で、差込口１１０の上側端部が床から３２ｍｍの位置となるように、試料作製用漏斗１００は形成される。   The sample preparation funnel 100 is formed so that the upper end of the sample container 300 is lower than the position of the upper end of the insertion port 110. For example, when the height of the sample container 300 is 30 mm, the sample preparation funnel 100 is placed on the floor, and the upper end of the insertion port 110 is positioned 32 mm from the floor. A funnel 100 is formed.

さらに、試料作製用漏斗１００は、試料容器３００が下側開口１０６の内側に入らない大きさとなるように形成される。具体的には、試料作製用漏斗１００は、支持脚部１１４の内径と下側開口１０６との平均値が試料容器３００の外径よりも小さくなるように形成される。例えば、試料容器３００の外径が、３５ｍｍであれば、試料作製用漏斗１００は、支持脚部１１４の内径が４５ｍｍかつ下側開口１０６が２０ｍｍとなるように形成される。これにより、試料容器３００の中心位置と試料作製用漏斗１００の中心位置とがずれた場合であっても、試料容器３００が下側開口１０６の内側に入ることを防止できる。   Furthermore, the sample preparation funnel 100 is formed so that the sample container 300 does not enter the inside of the lower opening 106. Specifically, the sample preparation funnel 100 is formed such that the average value of the inner diameter of the support leg 114 and the lower opening 106 is smaller than the outer diameter of the sample container 300. For example, if the outer diameter of the sample container 300 is 35 mm, the sample preparation funnel 100 is formed such that the inner diameter of the support leg 114 is 45 mm and the lower opening 106 is 20 mm. Thereby, even if the center position of the sample container 300 and the center position of the sample preparation funnel 100 are deviated, the sample container 300 can be prevented from entering the lower opening 106.

上記の設計に従えば、例えば、試料作製用漏斗１００は、支持脚部１１４の内径が４５ｍｍ、差込口１１０の外径２２ｍｍ、下側開口１０６が２０ｍｍ、かつ、差込口１１０の上側端部が床から３２ｍｍの位置となるように形成される。当該試料作製用漏斗１００は、外形が４５ｍｍ未満かつ３２．５ｍｍ以上、内径が２２ｍｍ以上、高さが３２ｍｍ未満の試料容器３００に対して適用される。   According to the above design, for example, the funnel 100 for sample preparation has an inner diameter of the support leg 114 of 45 mm, an outer diameter of the insertion port 110 of 22 mm, a lower opening 106 of 20 mm, and an upper end of the insertion port 110. The part is formed at a position of 32 mm from the floor. The sample preparation funnel 100 is applied to a sample container 300 having an outer shape of less than 45 mm, 32.5 mm or more, an inner diameter of 22 mm or more, and a height of less than 32 mm.

続いて、粉末試料４００を試料容器３００に入れる工程について説明する。図３乃至図６は、粉末試料４００を試料容器３００に入れる工程及び粉末試料４００を押し固める工程を示す図である。   Subsequently, a process of putting the powder sample 400 into the sample container 300 will be described. 3 to 6 are diagrams showing a process of putting the powder sample 400 into the sample container 300 and a process of pressing the powder sample 400.

まず、図３に示すように、試料容器３００は、試料作製用漏斗１００の内部に配置される。具体的には、実験用の作業台に蛍光Ｘ線分析に用いられる試料容器３００が置かれた状態で、当該試料容器３００に試料作製用漏斗１００が上から被せられる。   First, as shown in FIG. 3, the sample container 300 is disposed inside the sample preparation funnel 100. Specifically, the sample preparation funnel 100 is placed on the sample container 300 from above in a state where the sample container 300 used for fluorescent X-ray analysis is placed on the work bench for experiments.

ここで、試料容器３００は、蛍光Ｘ線分析装置の内部に載置されるため、試料容器３００の外形は蛍光Ｘ線分析装置に応じて定まる。本実施形態においては、試料容器３００の外形が円形状である場合について説明する。また、試料容器３００の形状に合わせて、図１及び図２で示したように、支持脚部１１４の形状が円筒状である場合について説明する。   Here, since the sample container 300 is placed inside the fluorescent X-ray analyzer, the outer shape of the sample container 300 is determined according to the fluorescent X-ray analyzer. In the present embodiment, a case where the outer shape of the sample container 300 is circular will be described. In addition, a case where the shape of the support leg 114 is cylindrical as illustrated in FIGS. 1 and 2 according to the shape of the sample container 300 will be described.

次に、図４に示すように、粉末試料４００は、スパチュラ等を用いて、試料作製用漏斗１００の上側開口１０４から投入される。上側開口１０４は、試料容器３００の内径よりも大きいことから、容易に粉末試料４００を入れることができる。   Next, as shown in FIG. 4, the powder sample 400 is introduced from the upper opening 104 of the sample preparation funnel 100 using a spatula or the like. Since the upper opening 104 is larger than the inner diameter of the sample container 300, the powder sample 400 can be easily put therein.

次に、図５に示すように、試料作製用漏斗１００を少し浮かせた状態でスパチュラで外側側面１１２を叩くことにより、試料作製用漏斗１００に振動を与える。これにより、粉末試料４００が内側側面１０８に付着している場合であっても、付着した粉末試料４００を試料容器３００に入れることができる。なお、試料測定用漏斗に振動を与える方法はこれに限られず、試料作製用漏斗１００で床を軽く叩くことにより、試料測定用漏斗に振動を与えてもよい。   Next, as shown in FIG. 5, the sample preparation funnel 100 is vibrated by tapping the outer side surface 112 with a spatula in a state where the sample preparation funnel 100 is slightly lifted. Thereby, even if the powder sample 400 is attached to the inner side surface 108, the attached powder sample 400 can be put into the sample container 300. Note that the method of applying vibration to the sample measuring funnel is not limited to this, and the sample measuring funnel 100 may be vibrated by lightly tapping the floor.

次に、図６に示すように、試料容器３００に入れられた粉末試料４００は、押し棒１０２で押し固められる。具体的には、試料容器３００に入れられた粉末試料４００に対して、押し棒１０２が押し付けられることにより、粉末試料４００は押し固められる。以上の工程により、粉末試料４００を試料容器３００に入れる作業は完了する。   Next, as shown in FIG. 6, the powder sample 400 put in the sample container 300 is pressed and hardened by the push rod 102. Specifically, the powder sample 400 is pressed and solidified by pressing the push rod 102 against the powder sample 400 placed in the sample container 300. Through the above steps, the operation of putting the powder sample 400 into the sample container 300 is completed.

なお、押し棒１０２は、粉末試料４００を押し固めた後、試料作製用漏斗１００と一体的に保管されてもよい。具体的には、試料作製用漏斗１００と、試料容器３００に挿入された試料を押し固める押し棒１０２とは、試料作製用具セットを構成してもよい。例えば、図７に示すように、押し棒１０２は、下側開口１０６に挿入されて保管される。ここで、押し棒１０２の当接部１１６が内側側面１０８と同じ傾きの面を有するように構成することで、押し棒１０２は、内側側面１０８を傷つけないように保管される。さらに、押し棒１０２が当接部１１６を有することにより、押し棒１０２の下端が床から浮いた状態で保管される。これにより、押し棒に汚れが付着することを防止できる。   The push rod 102 may be stored integrally with the sample preparation funnel 100 after the powder sample 400 is pressed and hardened. Specifically, the sample preparation funnel 100 and the push rod 102 for pressing and solidifying the sample inserted into the sample container 300 may constitute a sample preparation tool set. For example, as shown in FIG. 7, the push rod 102 is inserted into the lower opening 106 and stored. Here, by configuring the abutting portion 116 of the push rod 102 to have the same inclined surface as the inner side surface 108, the push rod 102 is stored so as not to damage the inner side surface 108. Further, since the push rod 102 has the contact portion 116, the lower end of the push rod 102 is stored in a state where it floats from the floor. Thereby, it can prevent that a dirt adheres to a push rod.

本考案は、上記の実施例に限定されるものではなく、種々の変形が可能である。試料作製用漏斗１００の構成は一例であって、これに限定されるものではない。上記の実施例で示した構成と実質的に同一の構成、同一の作用効果を奏する構成または同一の目的を達成する構成で置き換えてもよい。   The present invention is not limited to the above-described embodiments, and various modifications can be made. The configuration of the sample preparation funnel 100 is an example, and is not limited thereto. It may be replaced with a configuration that is substantially the same as the configuration shown in the above embodiment, a configuration that exhibits the same operational effects, or a configuration that achieves the same purpose.

[変形例]
例えば、試料作製用漏斗１００は、内側側面１０８と外側側面１１２の間が充填されていない構造であってもよい。具体的には、図８に示すように、試料作製用漏斗１００は、内側側面１０８と外側側面１１２の間に空間を有する構成としてもよい。これにより、試料作製用漏斗１００は、上記実施形態よりも、少ない材料で形成され、かつ、軽量となる。 [Modification]
For example, the sample preparation funnel 100 may have a structure in which the space between the inner side surface 108 and the outer side surface 112 is not filled. Specifically, as shown in FIG. 8, the sample preparation funnel 100 may have a space between the inner side surface 108 and the outer side surface 112. Thereby, the funnel 100 for sample preparation is formed with less material and is lighter than the above embodiment.

また、試料作製用漏斗が床に載置された状態で、床から下側開口１０６までの高さより高い試料容器３００の縁に当接する平坦部１１１は、例えば図８に示すように、差込口１１０の上端から外側側面１１２に向かって突き出た庇状の構成としてもよい。   Further, the flat portion 111 that contacts the edge of the sample container 300 that is higher than the height from the floor to the lower opening 106 in a state where the sample preparation funnel is placed on the floor is inserted as shown in FIG. It is good also as a bowl-shaped structure protruded toward the outer side surface 112 from the upper end of the opening | mouth 110. FIG.
