The present invention will be described in detail below based on one embodiment.
In the filter of the present invention, for example, as shown in FIGS. 1 and 2, an inner container (10) for temporarily storing a liquid substance (50) containing a solid such as powder or fine pieces is an outer container (30). The filter (1) has a structure that is detachably screwed to the inner container (10) and the outer container (30) to filter the liquid (50) and separate it into a liquid and a solid. .

内側容器(10)や外側容器(30)は、通常では、ポリエチレン、ポリプロピレン等の剛性と適度の弾性を有する熱可塑性樹脂を射出成形して作製するものである。   The inner container (10) and the outer container (30) are usually prepared by injection molding a thermoplastic resin having rigidity and moderate elasticity such as polyethylene and polypropylene.

そして、内側容器(10)は、底板(11)の周縁につなぎ部(12)を介して周壁(13)を立設して形成され、周壁の外側面には外側容器(30)の内側面に形成された外螺子(31)と螺合する内螺子(14)が形成されている。
つなぎ部(12)には貯留された液状物(50)を透過するための穴(15)が複数個設けられている。また、底板の下側面には凹凸(16)が形成されている。
The inner container (10) is formed by standing the peripheral wall (13) on the periphery of the bottom plate (11) via the connecting part (12), and the inner surface of the outer container (30) is formed on the outer surface of the peripheral wall. An inner screw (14) is formed which is screwed with the outer screw (31) formed on the inner surface.
The connecting portion (12) is provided with a plurality of holes (15) for allowing the stored liquid material (50) to pass therethrough. Moreover, the unevenness | corrugation (16) is formed in the lower surface of a baseplate.

また、外側容器(30)は、つぎのような部分から形成されている。すなわち、中央に流出口(32)が穿設され、流出口(32)の外側に溝(33)が環状に設けられている。   The outer container (30) is formed from the following parts. That is, the outflow port (32) is formed in the center, and the groove (33) is provided in an annular shape outside the outflow port (32).

図3、図4は本発明の濾過器の別の実施形態を示す説明図である。
図3において、内側容器の底板(11)は、中央に行くに従い突出する山型状に形成されており、底板の下側端縁には、中央が平坦で平坦部分(21)の周縁に外方に行くに従い上方に延びる傾斜部分(22)が形成された濾過パーツ(20)が、先端縁(23)を内側容器の底板(11)の端縁に嵌合により取り付けられている。
3 and 4 are explanatory views showing another embodiment of the filter of the present invention.
In FIG. 3, the bottom plate (11) of the inner container is formed in a mountain shape that protrudes toward the center, and the bottom edge of the bottom plate is flat at the center and outside the periphery of the flat portion (21). A filtration part (20) in which an inclined portion (22) extending upward as it goes is attached by fitting the tip edge (23) to the edge of the bottom plate (11) of the inner container.

そして取り付けられた濾過パーツの傾斜部分(22)の外側面には凹凸(24)が形成されている。   And the unevenness | corrugation (24) is formed in the outer surface of the inclination part (22) of the attached filtration part.

また、外側容器(30)は、流出口(32)とその外側に形成される溝(33)が、濾過パーツ(20)の平坦部分(21)に合わせて一段低く形成され、溝(33)の周縁に形成される外側底板(34)は、濾過パーツの傾斜部分(22)と密接するように外方に行くに従い上方に延びる傾斜部分(36)を形成して作製されている。   Further, the outer container (30) has an outlet (32) and a groove (33) formed outside the outlet (32) which is formed one step lower in accordance with the flat part (21) of the filtration part (20), and the groove (33). The outer bottom plate (34) formed on the periphery of the filter is formed by forming an inclined portion (36) extending upward as it goes outward so as to be in close contact with the inclined portion (22) of the filtration part.

濾過パーツ(20)も内側容器(10)や外側容器(30)と同様に、通常では、ポリエチレン、ポリプロピレン等の剛性と適度の弾性を有する熱可塑性樹脂を射出成形して作製される。   Similarly to the inner container (10) and the outer container (30), the filtration part (20) is usually produced by injection molding a thermoplastic resin having rigidity and moderate elasticity such as polyethylene and polypropylene.

図5は、本発明の濾過器のさらに別の実施形態を示す説明図で、図1と同様に濾過面を平面としたものである。   FIG. 5 is an explanatory view showing still another embodiment of the filter according to the present invention, in which the filtration surface is a plane as in FIG.

以下本発明の濾過器に共通したことであるが、内側容器(10)の底板(11)に、外側容器の外側底板(34)の内側面に密着する環状のコンタクトリング(18)を形成させることにより、内側容器(10)を回転させて下げ切った際、内側容器の底板(11)は外側容器の外側底板(34)に密着して隙間がなくなる。なお外側底板(34)、底板(11)は、流出口(32)に向かって5°程度傾斜させることで液体の流れをスムーズにすることができる。   Hereinafter, as common to the filter of the present invention, an annular contact ring (18) is formed on the bottom plate (11) of the inner container (10) to be in close contact with the inner surface of the outer bottom plate (34) of the outer container. Thus, when the inner container (10) is rotated and lowered, the bottom plate (11) of the inner container is in close contact with the outer bottom plate (34) of the outer container, and there is no gap. The outer bottom plate (34) and the bottom plate (11) can be made to flow smoothly by inclining about 5 ° toward the outlet (32).

外側容器(30)の外側底板(34)の内面に、内側容器の周壁(13)を保持し、かつ液漏れを防止するための環状突起(37)を設けても良い。このことにより内側容器を回転させて下まで下げた時、内側容器ががたついたりすることがない。液漏れを防止することもできる。   An annular protrusion (37) for holding the peripheral wall (13) of the inner container and preventing liquid leakage may be provided on the inner surface of the outer bottom plate (34) of the outer container (30). This prevents the inner container from rattling when the inner container is rotated and lowered to the bottom. Liquid leakage can also be prevented.

また底板(11)は、底板(11)に設けられたコンタクトリング(18)が図6(a)に示すように外側底板(34)からわずかに離間するように形成しておく。内側容器(10)を回転させて一番下まで押し下げた時にはじめて、底板(10)の弾性によってコンタクトリング(18)が外側底板(34)に接するように構成することで、例えば、コーヒーをいれる際の蒸らしや抽出(液止めされた状態)と、濾過(液が流れる状態)の切替えが可能となる。   The bottom plate (11) is formed so that the contact ring (18) provided on the bottom plate (11) is slightly separated from the outer bottom plate (34) as shown in FIG. 6 (a). Only when the inner container (10) is rotated and pushed down to the bottom, the contact ring (18) is in contact with the outer bottom plate (34) by the elasticity of the bottom plate (10). It is possible to switch between steaming and extraction (liquid stopped state) and filtration (liquid flowing state).

内側容器(10)の周壁端縁と、外側容器(30)の外側周壁の端縁に、それぞれ外方に向けて延びる内側鍔部(19)と外側鍔部(38)を形成しておくことにより、外側容器(30)に内側容器(10)を無理なく重ねて行くことができ、また、内側容器を内側鍔部を持って回転させることができる。   An inner collar part (19) and an outer collar part (38) extending outward are formed on the peripheral wall edge of the inner container (10) and the outer peripheral wall edge of the outer container (30), respectively. Thus, the inner container (10) can be reasonably stacked on the outer container (30), and the inner container can be rotated with the inner flange.

つぎに、コーヒー用濾過器を例にして具体的な使用例を説明する(図2参照)。   Next, a specific use example will be described using a coffee filter as an example (see FIG. 2).

外側容器(30)に内側容器(10)を重合させて、外側容器(30)をスタンド台(図示せず)で所定高さに保持し、外側容器(30)の流出口(32)の直下にコップ等の入れ物(図示せず)を載置する。   The inner container (10) is superposed on the outer container (30), the outer container (30) is held at a predetermined height by a stand base (not shown), and immediately below the outlet (32) of the outer container (30). A container (not shown) such as a cup is placed on the container.

内側容器(10)にコーヒー豆を挽いた粉末(51)を入れて熱湯を注ぐと、熱湯にコーヒー粉末の混ざった液状物(51)が形成され、コーヒー粉末の大部分は内側容器の底部に溜まり、残りの粉末の混ざった液状物(51)は、外側容器(30)と内側容器(10)の間のつなぎ部(12)に設けられた穴(15)から外側容器(30)と内側容器(10)の底板に取り付けられた濾過パーツ(20)の間の隙間を通過している間に、濾過パーツ(20)の傾斜部分(22)に形成された凹凸(24)の間を通って自動的に溝(33)に溜まる。   When powder (51) ground with coffee beans is put into the inner container (10) and hot water is poured, a liquid (51) in which the coffee powder is mixed with hot water is formed, and most of the coffee powder is at the bottom of the inner container. The liquid (51) that has accumulated and the remaining powder is mixed into the outer container (30) and the inner container from the hole (15) provided in the connecting part (12) between the outer container (30) and the inner container (10). While passing through the gap between the filtration parts (20) attached to the bottom plate of the container (10), it passes between the irregularities (24) formed in the inclined part (22) of the filtration parts (20). And automatically accumulates in the groove (33).

液状物中に含まれる微細な固体は溝の下に沈殿して、上澄みの液体、すなわち、コーヒー抽出液(52)のみが溝(33)から溢れて流出口(32)から外部に流れ出し、コップ等の入れ物に注がれることになる。   The fine solid contained in the liquid material settles under the groove, and only the supernatant liquid, that is, the coffee extract (52) overflows from the groove (33) and flows out from the outlet (32) to the outside. It will be poured into containers such as.

また、外側容器(30)に内側容器(10)を重合させる際、内側容器をしっかり回転させて、コンタクトリング(18)を外側容器の外側底板(34)の表面に密着させておくと、液状物(51)は隙間を伝わって流れ出ることがなくなり、液の流れが停止するので、コーヒー豆を挽いた粉末(51)に熱湯を注いだ後の蒸らし時間などの調節をすることができる。   Further, when the inner container (10) is polymerized in the outer container (30), the inner container is rotated firmly so that the contact ring (18) is brought into close contact with the surface of the outer bottom plate (34) of the outer container. Since the thing (51) does not flow out through the gap and the liquid flow stops, it is possible to adjust the steaming time after pouring hot water into the ground coffee beans (51).
