Abstract

A package for dispensing a granular product has a first hollow body member, a second hollow body member, and a pouring spout. The first hollow body member has a first exterior surface and opposite therefrom a first interior surface which defines a first internal volume. The second hollow body member has a second exterior surface, a second interior surface, a flow-regulating passage, and a dispensing passage separate from the flow-regulating passage. The second exterior surface defines a second external volume smaller than the first internal volume. Opposite the second exterior surface, the second hollow interior surface defines a second internal volume. The pouring spout is operatively connected to the dispensing passage. When the first internal volume is at least about 50% full of a granular product, the package may be tilted for dispensing at a dispensing angle which causes the granular product to flow from the first internal volume through the flow-regulating passage into the second internal volume and from the second internal volume through the dispensing passage out of the package. When the flow rate is measured and calculated at dispensing angles of 120°, 150° and 180°, the standard deviation is less than about 30% of the average flow rate for each dispensing angle.

Description

本発明は、顆粒状製品用のパッケージに関する。とりわけ、本発明は、顆粒状製品を注ぐのに使用される、顆粒状製品用のパッケージに関する。   The present invention relates to a package for a granular product. In particular, the present invention relates to a package for granular products used for pouring granular products.

食品、洗剤、粉体などの顆粒状製品、及び特に、食塩、粉、洗濯洗剤、自動食器洗い洗剤、スパイスなどの易流動性の顆粒状製品を貯蔵して分配するためのパッケージは、既知である。そのようなパッケージは、中の顆粒状製品を注ぎ出すのに使用される場合が多く、及び通常は、丸い口又は他の形状の開口部が付いた標準的な中空瓶からなる。顆粒状製品を分配すべき時、中空瓶が傾けられて、製品を口から分配する。瓶が傾けられた角度に依存して、顆粒状製品は、ゆっくり又は早くのいずれかで分配され、角度が大きければ大きいほど、顆粒状製品が、より早く分配される。   Packages for storing and dispensing granular products such as foods, detergents, powders, and especially free-flowing granular products such as salt, powder, laundry detergents, automatic dishwashing detergents, spices are known . Such packages are often used to pour out the granular product in and usually consist of a standard hollow bottle with a round mouth or other shaped opening. When the granular product is to be dispensed, the hollow bottle is tilted to dispense the product from the mouth. Depending on the angle at which the bottle is tilted, the granular product is dispensed either slowly or quickly, the larger the angle, the faster the granular product is dispensed.

そのようなパッケージは多数の用途に対して有用であるが、顆粒状製品を一定速度で分配するのが望ましい場合、例えば、分配した顆粒状製品の量を正確に測定しようとするときには、有用でない。そのような顆粒状製品については、顆粒状製品の予め定められた単一の「単位投与分」を提供する投与器具、又は瓶が回転された時に顆粒状製品の流れを塞き止める小さな穴などの、他の分配機構が開発されてきた。しかし、そのような場合でも、顆粒状製品の流れが連続でないか（すなわち、単位投与分の場合）、パッケージが保持された角度にまだ大きく依存するか、又は所望の場所に容易に注がれないかのいずれかである。加えて、そのようなパッケージは、人が急いでいる時、若年者による、又は年配者による使用には、複雑及び不便になる傾向がある。   Such a package is useful for many applications, but is not useful when it is desired to dispense the granular product at a constant rate, for example, when trying to accurately measure the amount of dispensed granular product. . For such granular products, dosing devices that provide a predetermined single “unit dose” of the granular product, or a small hole that blocks the flow of the granular product when the bottle is rotated, etc. Other distribution mechanisms have been developed. However, even in such cases, the flow of the granular product is not continuous (ie in the case of a unit dose), still highly dependent on the angle at which the package is held, or easily poured into the desired location. There is no one. In addition, such packages tend to be complex and inconvenient for use by young people or elderly people when people are in a hurry.

それ故に、分配角度の広い範囲にわたって実質的に同一の流量を提供し、所望の場所に正確に注ぐ、及び使用するのが容易で便利な、顆粒状製品を分配するためのパッケージが必要とされる。   Therefore, there is a need for a package for dispensing granular products that provides substantially the same flow rate over a wide range of dispensing angles, accurately pours into the desired location, and is easy and convenient to use. The

本発明は、第一中空本体部材、第二中空本体部材、及び注ぎ口を有する顆粒状製品を分配するためのパッケージに関する。第一中空本体部材は、第一外側表面と、これに反対側の第一内側容積を画定する第一内側表面とを有する。第二中空本体部材は、第二外側表面と、第二内側表面と、流量調節通路と、流量調節通路から離れた分配通路とを有する。第二外側表面は、第一内側容積より小さい第二外側体積を画定する。第二外側表面の反対側で、第二中空内側表面が、第二内側容積を画定する。注ぎ口は、操作可能に分配通路に連結されている。第一内側容積が顆粒状製品で少なくとも約５０％満たされている時、パッケージは、分配のために分配角度で傾け可能であり、このことが顆粒状製品を、第一内側容積から流量調節通路を通って第二内側容積に入らせ、及び第二内側容積から分配通路を通ってパッケージから流出させる。分配角度１２０度、１５０度、及び１８０度で、流量が測定されて計算される時、その標準偏差は、各分配角度についての平均流量の約３０％未満である。   The present invention relates to a package for dispensing a granular product having a first hollow body member, a second hollow body member, and a spout. The first hollow body member has a first outer surface and a first inner surface defining a first inner volume opposite thereto. The second hollow body member has a second outer surface, a second inner surface, a flow control passage, and a distribution passage that is remote from the flow control passage. The second outer surface defines a second outer volume that is less than the first inner volume. Opposite the second outer surface, the second hollow inner surface defines a second inner volume. The spout is operably connected to the distribution passage. When the first inner volume is at least about 50% full of granular product, the package can be tilted at a dispensing angle for dispensing, which causes the granular product to flow from the first inner volume to the flow control passage. Through the second inner volume and out of the package through the distribution passage from the second inner volume. When flow rates are measured and calculated at distribution angles of 120, 150, and 180 degrees, the standard deviation is less than about 30% of the average flow for each distribution angle.

本発明のパッケージは、分配角度の広い範囲にわたって実質的に同一の平均流量で顆粒状製品を分配できることが、今や判明した。これにより今度は、そのパッケージによって、特に若年者及び年配者が顆粒状製品を正しい量で正確に分配することがより容易及びより便利になる。加えて、驚くべきことに、流量調節通路は、第一内側容積内の突然の「なだれ」が分配通路から出る顆粒状粒子の規則的及び正確な流れを崩壊させるのを防ぐことによって、目標場所へより正確に顆粒状粒子の正確な流れを維持できることが判明した。更に加えて、本明細書のパッケージは特定の場所へ正確に注ぐ。   It has now been found that the package of the present invention can dispense granular products with substantially the same average flow rate over a wide range of dispensing angles. In turn, this package makes it easier and more convenient, especially for young and elderly people, to dispense the granular product in the correct amount and accurately. In addition, surprisingly, the flow control passage prevents the abrupt “avalanche” in the first inner volume from disrupting the regular and precise flow of granular particles exiting the distribution passage. It has been found that the precise flow of granular particles can be maintained more accurately. In addition, the packages herein pour precisely into specific locations.

本明細書における全ての温度は、特記されない限り摂氏（℃）である。本明細書で使用する時、用語「含む」は最終的な結果に悪影響を及ぼさない他の工程、成分、要素などを追加できることを意味する。この用語は「からなる」及び「から本質的になる」という用語を包含する。   All temperatures herein are in degrees Celsius (° C.) unless otherwise specified. As used herein, the term “comprising” means that other steps, ingredients, elements, etc. that do not adversely affect the final result can be added. This term encompasses the terms “consisting of” and “consisting essentially of”.

本発明は、例えば顆粒状の食品、顆粒状の洗剤や化学製品などの顆粒状製品を分配するためのパッケージを含む。本明細書における発明のある実施形態では、顆粒状製品は、食塩、粉、重曹、ベーキングパウダー、砂糖、及びこれらの混合物からなる群から選択される。本明細書における発明のある実施形態では、顆粒状の洗剤は、洗濯洗剤組成物、自動食器洗い組成物、消毒組成物、洗浄組成物、パーソナルクレンジング組成物、及びこれらの混合物からなる群から選択される。その顆粒状製品は、易流動性の顆粒状製品でなければならない。本明細書の一実施形態では、顆粒状製品は、球体、結晶体、立方体など、ほぼ規則的な形状を、好ましくは規則的な形状を有する。理論に束縛されるものではないが、典型的には、顆粒状製品中の粒子の形状がより規則的であればあるほど、顆粒状製品の易流動性特性がより良くなると考えられている。本発明における別の実施形態では、顆粒状製品は平均粒子径を有しており、これは当該技術分野において既知の方法により計算できる数平均粒子径であって、粒子径は個々の粒子上の最も遠い二点間の直線距離として定義される。本発明における一実施形態では、顆粒状製品は平均粒子径と、平均流量の約３０％未満、すなわち平均流量の約０％〜約３０％の標準偏差とを有する。   The present invention includes packages for dispensing granular products such as granular foods, granular detergents and chemical products. In certain embodiments of the invention herein, the granular product is selected from the group consisting of salt, flour, baking soda, baking powder, sugar, and mixtures thereof. In certain embodiments of the invention herein, the granular detergent is selected from the group consisting of laundry detergent compositions, automatic dishwashing compositions, disinfecting compositions, cleaning compositions, personal cleansing compositions, and mixtures thereof. The The granular product must be a free-flowing granular product. In one embodiment herein, the granular product has a generally regular shape, preferably a regular shape, such as a sphere, crystal, cube. Without being bound by theory, it is typically believed that the more regular the shape of the particles in the granular product, the better the free-flowing properties of the granular product. In another embodiment of the invention, the granular product has an average particle size, which is a number average particle size that can be calculated by methods known in the art, where the particle size is on individual particles. Defined as the straight line distance between the two furthest points. In one embodiment of the invention, the granular product has an average particle size and a standard deviation of less than about 30% of the average flow rate, that is, about 0% to about 30% of the average flow rate.

本明細書の図面は、必ずしも一定の比率の縮尺で描かれてはいない。   The drawings in this specification are not necessarily drawn to scale.

図１に転じると、パッケージ１００の表面を切り欠いた側面図を示しており、これは、第一外側表面１１２と第一外側表面１１２の反対側の第一内側表面１１４とを有する、第一中空本体部材１１０を有する。第一内側表面１１４は、第一内側容積１１６を画定し、これは更に、第一外側表面１１２が第一内側表面１１４と交わる場所に形成された口１１８と境界を接する。したがって、この実施形態では、第一内側容積１１６は、口１１８により形成される平面にて終了する。口１１８に対向して、パッケージ底１２０があり、これは図１では、パッケージ１００が安定して置かれるように平らである。   Turning to FIG. 1, a cutaway side view of the surface of the package 100 is shown, which includes a first outer surface 112 and a first inner surface 114 opposite the first outer surface 112. It has a hollow body member 110. The first inner surface 114 defines a first inner volume 116 that further borders a mouth 118 formed where the first outer surface 112 meets the first inner surface 114. Thus, in this embodiment, the first inner volume 116 ends at the plane formed by the mouth 118. Opposite the mouth 118 is a package bottom 120, which in FIG. 1 is flat to allow the package 100 to rest stably.

図１は、この実施形態では第一中空本体部材１１０とは別個の、第二中空本体部材１２２も示す。第二中空本体部材１２２は、第一内側容積１１６より小さい第二外側体積１２６を画定する、第二外側表面１２４を有する。本明細書の実施形態では、第二外側体積は、第一内側容積の約５０％未満である。第二中空本体部材１２２は又、第二外側表面１２４の反対側の第二内側表面１２８を有する。第二内側表面が、第二内側容積１３０を画定する。本明細書のある実施形態では、第二内側容積は、第一内側容積の約１％〜約２５％である。本明細書の別の実施形態では、第二内側容積は、第一内側容積の約２％〜約１５％である。第二中空本体部材１２２には、流量調節通路１３２が含まれ、これが、第二外側表面１２４から第二内側表面１２８に通じる。流量調節通路１３２から遠くに及び離れてあるのは分配通路１３４であって、これが、第二内側表面１２８から第二外側表面１２４に通じる。   FIG. 1 also shows a second hollow body member 122 that is separate from the first hollow body member 110 in this embodiment. The second hollow body member 122 has a second outer surface 124 that defines a second outer volume 126 that is smaller than the first inner volume 116. In embodiments herein, the second outer volume is less than about 50% of the first inner volume. The second hollow body member 122 also has a second inner surface 128 opposite the second outer surface 124. A second inner surface defines a second inner volume 130. In certain embodiments herein, the second inner volume is about 1% to about 25% of the first inner volume. In another embodiment herein, the second inner volume is about 2% to about 15% of the first inner volume. The second hollow body member 122 includes a flow control passage 132 that communicates from the second outer surface 124 to the second inner surface 128. Distant from and away from the flow regulation passage 132 is a distribution passage 134 that leads from the second inner surface 128 to the second outer surface 124.

In certain embodiments for granular detergents herein, the first inner volume is from about 150 mL to about 3 L, or from about 200 mL to about 1 L.

図１において、第二外側表面１２４は、接着剤１３６を介して、口１１８に固着される。しかしながら、第二外側表面は又、例えば、圧力封止、接着剤封止、ロッキング閉止、ねじタイプ閉止、スナップ嵌め閉止、熱封止、超音波封止、及び／又はプラグ封止によって口に固着されてもよく、並びに任意に、例えば顆粒状製品の酸化、空気からの水分の吸収、及び／又は顆粒状製品に対する水損傷を防止するために、望みに応じて気密及び／又は水密としてもよい。本明細書の実施形態では、第二外側表面は取外し可能に口に固着される。やはり図１において、分配通路１３２は第二外側表面１２４にて、縁部１３８と境界を接する。縁部１３８は口１１８に固着されており、その結果、第二中空本体部材１２２の大部分が第一内側容積１１６の中に含まれるが、これは必要なことではない。本発明において、第二中空本体部材は、少なくとも部分的に第一内側容積内にあることだけが必要とされる。   In FIG. 1, the second outer surface 124 is secured to the mouth 118 via an adhesive 136. However, the second outer surface can also be secured to the mouth by, for example, pressure sealing, adhesive sealing, locking closure, screw type closure, snap-fit closure, heat sealing, ultrasonic sealing, and / or plug sealing. And optionally may be airtight and / or watertight as desired to prevent, for example, oxidation of the granular product, absorption of moisture from the air, and / or water damage to the granular product. . In embodiments herein, the second outer surface is removably secured to the mouth. Still in FIG. 1, the distribution passageway 132 borders the edge 138 at the second outer surface 124. The edge 138 is secured to the mouth 118, so that the majority of the second hollow body member 122 is contained within the first inner volume 116, but this is not required. In the present invention, the second hollow body member need only be at least partially within the first inner volume.

図１において、分配通路１３４に連結されているのは、注ぎ口１４０であって、パッケージ１００が分配のために傾けられた時に、注ぎ口が顆粒状製品の方向を定める助けをする（図２参照）。第二中空本体部材１２２は、分配通路１３４に対向して基底１４２を有する。流量調節通路１３２が、口１１８の近辺から基底１４２まで延びる。加えて、基底１４２は流量調節通路１３２に向かって傾斜しており、その結果、パッケージ１００がパッケージ底１２０上に平らに置かれた時に第二内側容積１３０内に残る顆粒状製品が、流量調節通路１３２を通って第一内側容積１１６の中へ流れ戻る。   In FIG. 1, connected to the dispensing passage 134 is a spout 140 that assists in directing the granular product when the package 100 is tilted for dispensing (FIG. 2). reference). The second hollow body member 122 has a base 142 facing the distribution passage 134. A flow control passage 132 extends from the vicinity of the mouth 118 to the base 142. In addition, the base 142 is inclined toward the flow regulation passage 132 so that the granular product remaining in the second inner volume 130 when the package 100 is laid flat on the package bottom 120 is flow regulated. It flows back through the passage 132 into the first inner volume 116.

図２は、分配中に傾けられた、本発明のパッケージ１００の表面を切り欠いた側面図を示す。パッケージ底（図２には示さず）に垂直に引かれた及び図２において口１１８より形成される平面に対しても垂直である線Ａ−Ａが、地面に対して垂直に引かれた垂直線Ｂ−Ｂと分配角度αを形成する。顆粒状製品１４４を入れたパッケージ１００が約１５０度の分配角度αに傾けられる時、顆粒状製品１４４は矢印Ｃにより表されるように、第一内側容積１１６から流量調節通路１３２を通って第二内側容積１３０に流入する。顆粒状製品１４４は、次に、第二内側容積１３０から分配通路１３４を通り、矢印Ｄにより表されるように、注ぎ口１４０を出てキャップ１４６に流入する。キャップ１４６は、投与器具１４８と、投与する顆粒状製品１４４がどれだけの量かユーザーに知らせる計量インジケータ１５０とを有する。顆粒状製品が第二内側容積、したがって注ぎ口から実質的に一定の流量で流出するので、顆粒状製品を正確に測定して投与することが容易である。その上更に、図２の実施形態では、流量調節通路１３２は口１１８の近辺から基底１４２まで延びており、その結果、所与の分配角度例えば１５０度にて顆粒状製品１４４の実質的に全てが、第一内側容積１１６から流量調節通路１３２を通って第二内側容積１３０へ入り、分配通路１３４から流出する。図２において、基底１４２は、平らであって、想像線Ｅ−Ｅを画定する。口１１８も、想像線Ｆ−Ｆを画定する。基底角度γが、想像線Ｅ−ＥとＦ−Ｆの交差により形成される。   FIG. 2 shows a side view with the surface cut away of the package 100 of the present invention tilted during dispensing. A line AA drawn perpendicular to the package bottom (not shown in FIG. 2) and perpendicular to the plane formed by the mouth 118 in FIG. 2 is drawn perpendicular to the ground. A line BB and a distribution angle α are formed. When the package 100 containing the granular product 144 is tilted to a distribution angle α of about 150 degrees, the granular product 144 passes from the first inner volume 116 through the flow control passage 132 as indicated by arrow C. It flows into the second inner volume 130. The granular product 144 then passes from the second inner volume 130 through the dispensing passage 134, exits the spout 140 and flows into the cap 146 as represented by arrow D. The cap 146 includes a dispensing device 148 and a metering indicator 150 that informs the user how much granular product 144 is to be dispensed. Since the granular product flows out of the second inner volume, and hence the spout, at a substantially constant flow rate, it is easy to accurately measure and administer the granular product. Still further, in the embodiment of FIG. 2, the flow regulation passage 132 extends from the vicinity of the mouth 118 to the base 142 so that substantially all of the granular product 144 is at a given dispensing angle, eg, 150 degrees. Enters the second inner volume 130 from the first inner volume 116 through the flow regulation passage 132 and exits from the distribution passage 134. In FIG. 2, the base 142 is flat and defines an imaginary line EE. The mouth 118 also defines an imaginary line FF. A base angle γ is formed by the intersection of imaginary lines EE and FF.

図３は、顆粒状製品分配用の比較パッケージ２００の部分的な切欠き側面図を示しており、注ぎ穴２１０と注ぎ穴２１０の内部に対して傾いた平面２１２とを有する。しかし、比較パッケージ２００が約１００度〜約１８０度の様々な角度で傾けられる時、その中の顆粒状製品は、劇的に異なる流量で注ぎ穴２１０から流出する。   FIG. 3 shows a partial cutaway side view of a comparative package 200 for dispensing granular products, having a pour hole 210 and a flat surface 212 that is inclined with respect to the interior of the pour hole 210. However, when the comparative package 200 is tilted at various angles from about 100 degrees to about 180 degrees, the granular product therein flows out of the pour hole 210 at a dramatically different flow rate.

図４は、第二中空本体部材１２２とその中の流量調節通路１３２の拡大側面図を示す。流量調節通路１３２は、基底１４２から縁部１３８の近くまで延びる。流量調節通路１３２は、流量調節通路の最も広い部分として定義される及び顆粒状製品の平均粒子径よりかなり広い幅βを有する。図４において、その幅は口近辺から基底まで延びる。本明細書のある実施形態では、その幅は口に隣接する。本明細書の別の実施形態では、その幅は基底近辺に有る。本明細書の実施形態では、その幅は平均粒子径より少なくとも約５倍広く、又は平均粒子径より約５倍〜約１０００倍広く、又は平均粒子径より約１０倍〜約１００倍広い。理論により制限されるものではないが、そのような広い流量調節通路が、顆粒状製品の易流動特性を強めると考えられている。   FIG. 4 shows an enlarged side view of the second hollow body member 122 and the flow rate adjusting passage 132 therein. The flow control passage 132 extends from the base 142 to near the edge 138. The flow control passage 132 has a width β that is defined as the widest portion of the flow control passage and is significantly wider than the average particle size of the granular product. In FIG. 4, the width extends from the vicinity of the mouth to the base. In certain embodiments herein, the width is adjacent to the mouth. In another embodiment herein, the width is near the base. In embodiments herein, the width is at least about 5 times wider than the average particle size, or about 5 times to about 1000 times wider than the average particle size, or about 10 times to about 100 times wider than the average particle size. Without being limited by theory, it is believed that such a wide flow control passage enhances the free flow characteristics of the granular product.

流量試験方法：
本明細書で使用する時、「平均流量」という句は、分配角度が約１５０度である時に分配通路から流れる顆粒状製品の流量を記述する。平均流量を測定するために、第一内側容積が、通常は少なくとも５０％、好ましくは９０％の予め定められた容積の顆粒状製品で満たされる。パッケージを１５０度の分配角度に５秒間傾け、この時間中に分配通路を流れ出たビーズの体積を集めて重量測定し、その重量を５秒で割り算することによって、毎秒の流量が計算される。５秒間が完了する前に顆粒状製品の流れが止まった場合、及び／又はパッケージが完全に空になった場合には、顆粒状製品の流れが止まる／パッケージが完全に空になるのに要した時間によって、重量が割り算される。流量は、５回測定して計算される。これらの５つの計算された流量から、平均流量、標準偏差、及び流量の百分率としての標準偏差が、計算される。 Flow test method:
As used herein, the phrase “average flow rate” describes the flow rate of the granular product that flows from the dispensing passage when the dispensing angle is about 150 degrees. In order to measure the average flow rate, the first inner volume is usually filled with a predetermined volume of granular product of at least 50%, preferably 90%. The flow rate per second is calculated by tilting the package to a distribution angle of 150 degrees for 5 seconds, collecting and weighing the volume of beads that flowed out of the distribution passage during this time, and dividing that weight by 5 seconds. If the flow of the granular product stops before 5 seconds is complete and / or if the package is completely emptied, the flow of the granular product stops / necessary for the package to be completely emptied. The weight is divided by the time taken. The flow rate is calculated by measuring 5 times. From these five calculated flow rates, the average flow rate, standard deviation, and standard deviation as a percentage of the flow rate are calculated.

本明細書で使用する時、用語「実質的に一定の流量」は、分配角度が１２０度、１５０度、及び１８０度の分配角度で測定される時、各分配角度についての標準偏差が平均流量の約３０％未満、すなわち平均流量の約０％〜約３０％である平均流量で、顆粒状製品がパッケージから連続して流れ出ることを表す。流量がこれらの特性を有しているか否か決定するために、上記流量試験方法が１５０度の分配角度の代わりに、１２０度及び１８０度の分配角度にも実施される。   As used herein, the term “substantially constant flow rate” means that the standard deviation for each distribution angle is the average flow rate when the distribution angle is measured at 120, 150, and 180 degree distribution angles. Represents a continuous flow of the granular product out of the package at an average flow rate of less than about 30%, i.e., from about 0% to about 30% of the average flow rate. In order to determine whether the flow rate has these characteristics, the flow test method described above is performed at 120 degree and 180 degree distribution angles instead of 150 degree distribution angles.
