Description

本発明は、液体を入れるプラスチック容器、金属容器の注水時の脈打ちを防止、流量調整することを目的に発明されたものである。  The present invention has been invented for the purpose of preventing pulsation and adjusting the flow rate of a plastic container and a metal container into which liquid is poured.

ペットボトルやアルミボトルなどの容器から液体を注ぐ場合、主流の狭口の容器は脈打ちによりはねたり、流速が遅くなり、逆に広口の容器は大量に流出してこぼしたりして不便であった。  When pouring liquid from containers such as PET bottles and aluminum bottles, mainstream narrow-mouthed containers are inconvenient because they bounce due to pulsation, the flow speed slows down, and conversely, wide-mouthed containers spill out and spill. It was.

ペットボトルの口は軽量化を目的とした構造により狭口が主流となる一方、茶製品などの大型容器の市場拡大、水製品など調理用途など一回の使用量が多くなるなど、この不便さが際立ってきており、本件はこの問題の解決するために発明されたものである。  Narrow mouths are the mainstream for PET bottle mouths because of the structure aimed at reducing weight, but this is inconvenient, such as expanding the market for large containers such as tea products, and increasing the amount of use once for cooking purposes such as water products. This issue has been invented to solve this problem.

広口のペットボトルが以前にあったが、流量が多すぎて、こぼしやすく、流量を調整するために広口の一部を塞ぐと、狭口と同様に脈打ちが発生する。  There was a wide-mouthed PET bottle before, but the flow rate is too high, it is easy to spill, and when a part of the wide-mouth is closed to adjust the flow rate, pulsation occurs like a narrow mouth.

リサイクル意識の高まりによる容器原材料の削減、ペットボトルの強度保持、現状の製造工程などにより、狭口が今後しばらくの期間は主流であることに変わりはないものと思われる。  Narrow mouths are expected to remain mainstream for some time in the future due to the reduction of container raw materials due to increased awareness of recycling, the maintenance of PET bottle strength, and the current manufacturing process.

一方、先述の家庭内調理用途などで多く利用される水製品、航空機内での飲料サービス、大型飲食店などの業務用途に於いては、適量の流量で、すばやく、はねることなく注水することのできる容器、及び製品に対する需要が確実に存在する。  On the other hand, in the above-mentioned water products that are frequently used for cooking at home, for beverage services on airplanes, and for business purposes such as large restaurants, water can be injected quickly and without splashing at an appropriate flow rate. There is certainly a need for containers and products that can be made.

従来は管を取り付けて脈打ちを防止する手法も考案されたが、製造工程、衛生管理に関する難点により普及が遅れているため、本考案は現状の製造工程、衛生管理及び省資源を勘案し、自然原理を応用した容器の構造変化により問題を解決すべく発明されたものである。  Conventionally, a method for preventing pulsation by attaching a pipe has been devised, but since the spread has been delayed due to difficulties related to the manufacturing process and hygiene management, the present invention takes into account the current manufacturing process, hygiene management and resource saving, It was invented to solve the problem by changing the structure of the container applying the principle.

脈打ちの原因は注水口と吸気口が同一で、注水により容器内圧が変化することで容器内への吸気が断続的になされるために起こるものである。  The cause of pulsation occurs because the water inlet and the air inlet are the same, and the intake pressure into the container is intermittently caused by the change in the internal pressure of the container due to the water injection.

これを解決するためには、常に吸気ができるように外気との容器内の空気がたまっている部分をつなぐ気道を確保しておくことが必要とされる。  In order to solve this, it is necessary to secure an airway that connects a portion where the air in the container accumulates with the outside air so that the air can be always inhaled.

現在大量に流通されている2リットル容量の飲料製品を注ぐ場合、水平線と容器の口の中心線(7)との間の角度が30度以下では、口(2)の先端の一点(3)と容器の肩(29)との間の気道は確保できず、容器内の水位が容器の傾斜角度に従い定まる所定の位置に下がるまで脈打ちを繰り返す。  When pouring a 2 liter beverage product that is currently distributed in large quantities, if the angle between the horizontal line and the center line (7) of the container mouth is 30 degrees or less, one point (3) at the tip of the mouth (2) The airway between the container and the shoulder (29) of the container cannot be secured, and pulsation is repeated until the water level in the container falls to a predetermined position determined according to the inclination angle of the container.

一方、注水時に容器を傾ける角度は先述の気道が確保される水平線に対して30度に対して、容器を握った位置や個人差はあるものの一般的には20度前後になるため、開封後しばらくの間の注水に於いては外気と容器内をつなぐ気道が確保できず脈打ちが発生し、容器内の液量が減少し気道が確保されるまでしばらくこの状態が継続する。  On the other hand, the angle at which the container is tilted at the time of pouring water is generally around 20 degrees, although there are differences in the position where the container is held and the individual, with respect to 30 degrees with respect to the horizontal line where the airway is secured as described above. In the case of water injection for a while, the airway connecting the outside air and the inside of the container cannot be secured, and pulsation occurs, and this state continues for a while until the amount of liquid in the container decreases and the airway is secured.

本発明は容器の上面または側面にくぼみ(17)、または容器の内部に仕切り板(18)を容器の口(2)と容器側面、または肩(29)の間に施すことで、容器の口(2)とくぼみ(17)、または仕切り板(18)の間に空気がとどまる部分(21)を創り、容器を30度以下に傾けても口の先端の一点(3)と容器内にある空気がとどまる部分(21)との間の気道を確保できるようにこのくぼみ(17)、または仕切り板(18)を施し、口(2)内部で発生する脈打ちを防止するものである。  The present invention provides a container mouth by providing a recess (17) on the top or side of the container or a partition plate (18) inside the container between the container mouth (2) and the container side or shoulder (29). (2) Create a part (21) where the air stays between the indentation (17) or the partition plate (18), and even if the container is tilted to 30 degrees or less, it is in the container with one point (3) at the tip of the mouth This indentation (17) or partition plate (18) is provided so as to ensure an airway between the portion where the air stays (21), and the pulsation generated inside the mouth (2) is prevented.

また、くぼみ(17)、または仕切り板(18)の先端に溝などを施し、容器内に吸引された空気が最初にとどまる部分(21)から更に肩(29)に吸い込まれていく際の吸気ができるだけ円滑に行われ容器内で発生する脈打ちをできるだけ和らげることで、注水時の脈打ち緩和効果が得られるとともに、注水量の制御、安定がなされるものである。  Further, a groove or the like is provided at the tip of the indentation (17) or the partition plate (18), so that the air sucked into the container is sucked into the shoulder (29) from the portion (21) where it first remains. Is performed as smoothly as possible, and the pulsation generated in the container is moderated as much as possible, so that the pulsation mitigating effect at the time of water injection can be obtained, and the water injection amount can be controlled and stabilized.

また本発明は、ペットボトルなど内部に圧力を加えて成形する容器の製造工程、容器内に液体を注入する製品の製造工程を勘案することが実用上で重要な条件となっているため、これらの点が十二分に考慮されて発明されている。  Further, in the present invention, it is a practically important condition to consider the manufacturing process of a container that is molded by applying pressure to the inside such as a plastic bottle, and the manufacturing process of a product that injects a liquid into the container. This point has been invented with sufficient consideration.

以下に発明の効果を容器の側面にくぼみ(17)を施した発明の一例を示した図3で説明する。  The effect of the invention will be described below with reference to FIG. 3 showing an example of the invention in which a recess (17) is provided on the side of the container.

容器本体(1)の狭い2つの側面に、くぼみ(17)を1箇所づつ施し、その先端(19)に約5ミリメートル幅の容器の口から容器の底の方向に向かう溝が施されている。  Two narrow sides of the container main body (1) are provided with one recess (17), and a groove is provided at the tip (19) from the mouth of the container having a width of about 5 millimeters toward the bottom of the container. .

このくぼみ(17)の先端に施された溝の最低位部(20)は口(2)の先端の内径の一点(3)から引かれた垂直線(4)より口(2)の中心線(7)に2ミリメートル程度近い位置にあり、先端(19)との高低差が約3ミリメートルとした。  The lowest portion (20) of the groove formed at the tip of the recess (17) is the center line of the mouth (2) from the vertical line (4) drawn from one point (3) of the inner diameter of the tip of the mouth (2). It was at a position close to (2) about 2 millimeters, and the height difference from the tip (19) was about 3 millimeters.

狭口の場合は、これにより、溝の最低位部(20)で最も口(2)の中心線(7)に近い個所は約5ミリメートルに位置することになる。  In the case of a narrow mouth, this places the location closest to the center line (7) of the mouth (2) in the lowest part (20) of the groove at about 5 millimeters.

この容器(1)を一方のくぼみ(17)が真上になるように真横に倒していくと、口(2)とくぼみ(17)間にある空気がとどまる部分(21)と容器外部の間に気道でき、脈打ちが起きずに放水されていく。  When this container (1) is tilted sideways so that one of the indentations (17) is directly above, the space (21) between the mouth (2) and the indentation (17) stays between the outside (21) and the outside of the container. The airway is opened and water is discharged without pulsation.

この後、真横に放置すると先の気道は容器外部とくぼみ(17)までつながり、くぼみの最低位部(20)よりわずかながら下の部分で遮断される。  After this, if left sideways, the previous airway is connected to the outside of the container up to the indentation (17), and is blocked at a portion slightly below the lowest position (20) of the indentation.

この後、容器内の液体は放水され続け、代わりに容器外部より口(2)内に確保された気道により取り込まれた空気は最低位部(20)を断続的に通過し、容器の肩(29)に向かって吸引される。  Thereafter, the liquid in the container continues to be discharged, and instead, air taken in from the outside of the container by the airway secured in the mouth (2) intermittently passes through the lowest part (20), and the shoulder ( 29).

この吸引は円滑に行われ、くぼみ(17)により低く保たれている水位(24)の水面はわずかには上下するものの、口(2)を塞ぐことなく継続して口(2)内に気道が確保される。  Although this suction is performed smoothly, the water level of the water level (24) kept low by the depression (17) rises and falls slightly, but continues without closing the mouth (2) and into the airway (2). Is secured.

このため、放水は脈を打つことなく円滑に行われ、この状態はくぼみ(17)により高く保たれた水位(23)が溝の最低位部(20)付近に下がるまで継続され、その後も同じ高さになった水位(23)と(24)が口の内径の最低位と同じ高さになるまで円滑に継続される。  For this reason, the water discharge is smoothly performed without pulsing, and this state is continued until the water level (23) kept high by the depression (17) is lowered near the lowest part (20) of the groove, and the same thereafter. It continues smoothly until the raised water levels (23) and (24) reach the same height as the lowest of the inner diameter of the mouth.

実際に消費者が利用する場合は容器を倒して放置することはないが、水平線に対して30度以下、0度以上の角度まで容器を傾けた場合、傾ける速さや丁寧さにより多少の差は生じるものの、容器内の水位(23)の水面の波打ちはくぼみ(17)により遮断され、水位(24)への影響は大幅に軽減され、水位(24)はほぼ一定に保たれ、先述の放置した状態とほぼ同様の効果が得られる。  When the consumer actually uses the container, the container is not dropped and left unattended, but when the container is tilted to an angle of 30 degrees or less and 0 degrees or more with respect to the horizon, there is a slight difference depending on the tilting speed and politeness. Although it occurs, the undulation of the water level (23) in the container is blocked by the depression (17), the effect on the water level (24) is greatly reduced, and the water level (24) is kept almost constant. The same effect as that obtained can be obtained.

更にこの溝の幅、数、形状により放水量も制御され、溝の最低位部と容器の口の位置関係により対応可能な傾斜角度の範囲が定まる。  Further, the amount of water discharged is controlled by the width, number, and shape of the groove, and the range of the inclination angle that can be handled is determined by the positional relationship between the lowest part of the groove and the mouth of the container.

また、一定の内径の口を有する容器で放水速度を早くして放水量を増やすには、水位(23)と(24)の高低差を大きくすること、すなわち容器の口を容器側面に施し、その側面が下、くぼみ(17)が上になるように口(2)とくぼみ(17)を施した図10、図11の構造とすると良い。  Further, in order to increase the water discharge rate by increasing the water discharge rate with a container having a constant inner diameter mouth, increase the level difference between the water levels (23) and (24), that is, apply the container mouth to the side of the container, The structure shown in FIGS. 10 and 11 is preferably provided with the mouth (2) and the recess (17) so that the side faces are downward and the recess (17) is upward.

同じ内径の口を有するペットボトルで従来の2リットル用容器と本発明の図12の仕切り板(18)の先端に5ミリメートル幅の溝を3箇所施した2リットル用容器で放水完了までの時間を比べると、本発明品は従来の5分の3の時間で全量放水することが可能となり、先述の溝の形状や数、水位(23)と(24)の水位差を大きくするとさらにその格差は拡大した。  Time required to complete water discharge with a conventional 2 liter container having a mouth of the same inner diameter and a 2 liter container having three 5 mm wide grooves at the tip of the partition plate (18) of FIG. 12 of the present invention. The product of the present invention can discharge the entire amount in three-fifths of the conventional time, and the difference between the shape and number of the grooves and the water level difference between the water levels (23) and (24) is further increased. Expanded.

また繰り返しくぼみ(17)、仕切り板(18)の形状を変えて行ったテストでも放水速度はもとより、安定した放水量で、脈打ちすることもなく円滑な放水がなされ、はねることもなく、広口のように不用意に大量に放水されこぼしたりすることもなく、極めて有効な効果が得られた。  Also, in tests conducted by repeatedly changing the shape of the indentation (17) and the partition plate (18), not only the water discharge speed, but also a stable water discharge, smooth water discharge without pulsation, no splash, In this way, a very effective effect was obtained without inadvertently discharging a large amount of water and spilling it.

本発明で効果を十分に発揮するためには、くぼみ(17)や仕切り板(18)の先端が口の中心線(7)付近に位置していることが好ましく、ペットボトルの製造工程を勘案すると、図4の形状で片側だけにくぼみ(17)を施し、くぼみ(17)の先端の中央部分に溝を施したものが実用的である。  In order to exhibit the effect sufficiently in the present invention, it is preferable that the tip of the indentation (17) or the partition plate (18) is located near the center line (7) of the mouth, taking into account the manufacturing process of the plastic bottle. Then, it is practical to use the shape of FIG. 4 in which a recess (17) is provided only on one side, and a groove is provided in the center of the tip of the recess (17).

一方、内部を加圧して成形するペットボトルと異なり、型で成形して製造する容器の場合は、図11の形状のものが効果も大きく有効である。  On the other hand, unlike a plastic bottle that is molded by pressurizing the inside, a container having a shape shown in FIG.

また、容器内に液体を注入する製品の製造を勘案すると、仕切り板(18)、またはくぼみ(17)の上部は先端が下に向いているものが好ましい。  In consideration of manufacturing a product for injecting liquid into the container, it is preferable that the upper part of the partition plate (18) or the depression (17) has a tip facing downward.

図12、図13で示されている形状で、容器内部に取り付けた仕切り板(18)の代わりに同位置の容器側面にくぼみ(17)を施した2リットル容量のペットボトルに関して実施例を示す。  12 and FIG. 13, an embodiment is shown for a 2 liter PET bottle having a recess (17) on the side surface of the container at the same position instead of the partition plate (18) mounted inside the container. .

容器本体(1)の原型は外径の直径約28ミリメートル、内径の直径約20ミリメートルの狭い口を有する底面が長方形状の一般的なペットボトルとする。  The prototype of the container body (1) is a general PET bottle having a narrow mouth with a narrow mouth having an outer diameter of about 28 mm and an inner diameter of about 20 mm.

この容器(1)に、口(2)の最も高い内径の中心点(6)から垂直に5センチメートル下の高さから容器側面で幅の狭い側面をくぼませ始め、この部分より10ミリメートル下の高さに頂点、更に5ミリメートル下の高さでもとの側面側へ戻るくぼみ(17)を施す。  The container (1) begins to be recessed from the center point (6) of the highest inner diameter of the mouth (2) with a narrow side at the side of the container from a height of 5 centimeters below and 10 millimeters below this part. A dent (17) is applied to the top side and to the side surface at a height of 5 millimeters below.

このくぼみ(17)の先端(19)は、口(2)の中心線(7)を5ミリメートル超えた位置まで伸ばし、水平で、幅の狭い容器側面と平行な直線状で、容器の幅の広い2つの側面を両端としている。  The tip (19) of this indentation (17) extends to a position that is more than 5 millimeters above the center line (7) of the mouth (2), is a straight line parallel to the horizontal side of the narrow container, and the width of the container Two wide sides are at both ends.

このくぼみ(17)の先端(19)の中央に、深さ10ミリメートル、幅15ミリメートルの低部が平らになっている溝を上から下へ垂直に施す。  In the center of the tip (19) of this indentation (17), a groove with a flat bottom of 10 millimeters deep and 15 millimeters wide is applied vertically from top to bottom.

流速を早めたい場合は、くぼみ(17)先端(19)の容器の広い側面と接している両端付近に、深さ10ミリメートルの溝を狭く施すことで可能となるため、必要に応じて施す。  If it is desired to increase the flow velocity, it becomes possible by narrowing a groove having a depth of 10 mm in the vicinity of both ends of the indentation (17) and the tip (19) in contact with the wide side surface of the container.

最後に、注水する際に方向が明確にわかるように、注水方向を示す印(25)を容器の側面または上面に施す。  Finally, a mark (25) indicating the direction of water injection is applied to the side surface or top surface of the container so that the direction can be clearly seen when water is injected.

これらは全て容器本体を成型する型に凹凸を施すことで、容器の成型と同時に施される。  All of these are applied simultaneously with the molding of the container by forming irregularities on the mold for molding the container body.

先述の通り本発明は、従来より不便であった脈打ちが防止され、流速も従来より約1.5倍早く、尚かつ流量も安定しており、極めて優れた効果を提供するものである。  As described above, the present invention prevents pulsation, which has been inconvenient compared to the prior art, has a flow velocity that is about 1.5 times faster than the prior art, and has a stable flow rate, providing an extremely excellent effect.

くぼみ(17)を施すために必要な容器本体(1)の材料の増加は、くぼみの形状によるが6%前後で、口(2)の配置によりこれ以下に削減が可能である。  The increase in the material of the container body (1) necessary for applying the recess (17) is around 6% depending on the shape of the recess, and can be reduced to less than this by the arrangement of the mouth (2).

また、従来の流速に設定した場合は更に口(2)を小さくすることも可能でこの分の容器材料を削減することも可能で、これに付随するキャップの原材料削減も可能である。  Further, when the conventional flow rate is set, the opening (2) can be further reduced, and the container material can be reduced by this amount, and the cap raw material accompanying this can be reduced.

口の形状に関しては、従来の広口は従来の狭口に対する口(2)部分に使用する材料は約1.5倍で、キャップに関しても同様で、厚みも容器本体(1)に比べて厚く、容器メーカーが狭口に傾向する原材料削減の理由ともなっているほどこの違いは大きい。  Regarding the shape of the mouth, the conventional wide mouth is about 1.5 times the material used for the mouth (2) portion of the conventional narrow mouth, the cap is the same, and the thickness is also thicker than the container body (1). The difference is so great that it is also the reason why container manufacturers tend to reduce raw materials.

発明の効果により付加価値づけがされ、従来と異なる着眼点で更なる原材料の削減の検討が可能で、容器メーカー、製品メーカーなどによる採用の可能性は大き。  Added value is added by the effect of the invention, and it is possible to consider further reduction of raw materials from a different point of view than before, and the possibility of adoption by container manufacturers, product manufacturers, etc. is great.

実際、本発明に至る間に製品メーカー、量販店より従来の問題に関しての解決の依頼もあり、また従来問題の解決を妨げていた容器の製造工程に起因する問題に関しても、本発明により解決されたため、早期に利用が開始されることが見込まれる。  In fact, during the course of the present invention, there have been requests from the product manufacturers and mass retailers to solve the conventional problems, and the problems caused by the manufacturing process of the containers that have prevented the conventional problems from being solved are also solved by the present invention. Therefore, the use is expected to start early.
