Description

本発明は、外部から圧力、温度、密閉状態等の内容液の収納状態を知ることができる表示機能を有する液体収納容器に関する。   The present invention relates to a liquid storage container having a display function capable of knowing the storage state of contents liquid such as pressure, temperature, sealed state, and the like from the outside.

特許文献1には、充填した内容液の温度を適正に検出することができる示温ラベルを胴部に貼付した容器に関する発明が記載されており、例えばワインやビールのように「飲み頃」温度があるような飲料等が充填される容器では、充填された内容液である飲料が「飲み頃」温度であるかどうかを判断することができ便利に使用することができるとしている。   Patent Document 1 describes an invention related to a container in which a temperature indicating label capable of appropriately detecting the temperature of a filled content liquid is attached to a body part. For example, a “drinking” temperature such as wine or beer is described. In a container filled with a certain beverage or the like, it can be determined whether or not the beverage, which is the filled content liquid, has a “drinking temperature” and can be used conveniently.

また、市販の容器製品では悪戯等による不正開放を防止したり、不正開放の有無が判るようにさまざまな工夫がされている、たとえば容器全体、あるいはキャップ等の密閉に係わる部分をフィルムで覆うのも一つの方法である。また、壜体では特許文献2にあるように、キャップの下端部に破断片を介して口筒部に組み付く係止筒を設けて、キャップを開封する際には破断片を破断するように構成したものがよく使われており、これにより不正開放を防止したり、不正開放の有無を確認できるようにしている。

In addition, commercially available container products have been devised in various ways to prevent unauthorized opening due to mischief, etc., and to detect the presence or absence of unauthorized opening. For example, covering the entire container or the part related to sealing such as a cap with a film Is one way. Further, as disclosed in Patent Document 2, the casing is provided with a locking cylinder that is assembled to the mouth tube portion via the broken piece at the lower end portion of the cap so that the broken piece is broken when the cap is opened. The ones that have been configured are often used to prevent unauthorized opening and to check for unauthorized opening.

しかしながら、示温ラベルを貼付する方法は、直接内容液の温度に対応しているわけではなく、容器の材質、容器の置かれている雰囲気温度の影響を受けやすい、あるいは繰り返して使用したり紫外線にあてると機能が低下する等の問題を有し、また多数ある同種の商品のなかで、自己の商品に目を向けさせる効果、所謂アイキャッチ効果という観点からは、単にラベルの色が変化したり、発色あるいは消色したりするだけで面白みに欠けるという不満もある。
また、不正開放防止、あるいは不正開放の有無を認識するための上記方法についても単に開栓、あるいは開封により部材の一部が破断されたり、フィルム等が破断するだけで意外性や、面白みに欠けるものであり、また一目でその状態が確認できない場合もある。
However, the method of applying a temperature label does not directly correspond to the temperature of the contents liquid, and is easily affected by the material of the container and the ambient temperature in which the container is placed, or is used repeatedly or exposed to ultraviolet rays. There are problems such as reduced function when touched, and among the same type of products, the color of the label simply changes from the viewpoint of the effect of turning your eyes on the product, the so-called eye catching effect. There is also a complaint that it is not interesting just by coloring or decoloring.
In addition, the above-described method for preventing unauthorized opening or recognizing the presence or absence of unauthorized opening is not surprising or interesting just by opening or opening a part of the member or breaking a film or the like. In some cases, the state cannot be confirmed at a glance.

本発明は、液体収納容器において、一目で内容液の圧力、温度、密閉状態等の収納状態を認識できる表示機能を創出することを課題とし、もって使用者が外部から一目で内容液の温度等の状態を認識できると共に、格段のアイキャッチ効果を発揮する液体用容器を提供することを目的とする。   An object of the present invention is to create a display function capable of recognizing a storage state such as pressure, temperature, sealed state, etc. of a content liquid at a glance in a liquid storage container. It is an object of the present invention to provide a liquid container that can recognize the above state and that exhibits a remarkable eye-catching effect.

上記技術的課題を解決する方法のうち、請求項1記載の発明の方法は、液体収納容器において、透明な容器本体内に浮沈子を挿入し、この浮沈子が、収納される内容液中で密閉された容器本体内の圧力状態によって浮沈し、この浮沈子の位置により内容液の収納状態が認識できるように構成すること、にある。   Among the methods for solving the above technical problem, the method of the invention according to claim 1 is a liquid storage container in which a floating sink is inserted into a transparent container body, and the floating sink is contained in the stored content liquid. It is configured to float and sink according to the pressure state in the sealed container body, and to recognize the storage state of the content liquid by the position of the float and sink.

請求項1記載の上記構成により、容器本体内の圧力状態は、内容液を充填し閉栓した後の内容液の温度変化、内容液からの揮発成分の量、内容液(容器)の密封状態等によりさまざまに変化するので、容器の外側から、圧力状態によって浮沈する浮沈子の位置によりこれら内容液の状態を知ることができる。
すなわちこの浮沈子により容器本体内の圧力状態を介して、内容液の状態を知らせる表示機能(モニター機能、あるいはインジケータ機能とも云える。)を発揮させることができる。
また、浮沈子の浮沈挙動により、自己の商品に目を向けさせるアイキャッチ効果を遺憾なく発揮させることもできる。
なお、本発明に使用する容器本体における透明とは、半透明も含めるものとする。また、内容液は透明、あるいは半透明であることが望ましいが、浮沈子の上端を液面の上にまで浮上させるケースでは不透明であってもよい。
According to the above configuration of claim 1, the pressure state in the container body is such that the temperature of the content liquid after filling and closing the content liquid, the amount of volatile components from the content liquid, the sealed state of the content liquid (container), etc. Therefore, from the outside of the container, the state of these liquid contents can be known from the position of the float or sink that floats or sinks due to the pressure state.
That is, the floating function enables a display function (also referred to as a monitor function or an indicator function) to notify the state of the content liquid through the pressure state in the container body.
In addition, the eye-catching effect of turning your eyes on your product can be demonstrated without regret by the behavior of the float.
In addition, translucency in the container main body used for this invention shall also include translucent. The content liquid is preferably transparent or semi-transparent, but may be opaque in the case where the upper end of the float is floated above the liquid surface.

ここで、本発明に使用される浮沈子は、容器本体内の圧力の変動により内容液中を浮上あるいは沈降するものであればよいが、合成樹脂製の小型の、内容液が出入りする開口部を有した中空成形体と、作用する重力を調整すると共に浮沈姿勢を制御するための金属製等の比重の大きな材料から成る錘から構成されたものをよく使用する。
そして、この浮沈子は開口部を下端にした起立状態で浮沈姿勢を保ちながら内容液中に位置し、中空成形体の中に容器本体内の圧力の大きさに応じた量の内容液が進入し、この進入量により作用する浮力が決まり、この浮力と重力のバランスによって内容液中で浮上したり、沈降したりする。
Here, the float / sink used in the present invention is not limited as long as it floats or sinks in the content liquid due to pressure fluctuations in the container body, but is a small synthetic resin opening through which the content liquid enters and exits. Often used is a hollow molded body having a weight and a weight made of a material having a large specific gravity such as a metal for adjusting the acting gravity and controlling the floating posture.
And this float and sink is positioned in the content liquid while maintaining the floating and sinking posture in the standing state with the opening at the lower end, and the content liquid of an amount corresponding to the pressure in the container body enters the hollow molded body. However, the buoyancy acting by this amount of entry is determined, and it floats or sinks in the content liquid by the balance between this buoyancy and gravity.

請求項2〜4に係る発明は内容液の温度状態を示す表示機能に係るものであり、請求項2記載の発明の手段は、請求項1記載の発明において、密閉収納される内容液の温度変化に伴う容器本体内の圧力の変化により、浮沈子が浮上あるいは沈降する構成とし、該浮沈子の位置により内溶液の温度状態が認識できるようにすること、にある。   The invention according to claims 2 to 4 relates to a display function indicating the temperature state of the content liquid, and the means of the invention according to claim 2 is the temperature of the content liquid sealed and stored in the invention according to claim 1. The structure is such that the floating sediment floats or sinks due to the change in pressure in the container body accompanying the change, and the temperature state of the internal solution can be recognized by the position of the floating sediment.

内容液を収納して密閉した状態の容器では、内容液の温度によって特に液面上に存在する気体が膨張あるいは収縮して容器本体内の圧力が変動するが、請求項2記載の上記構成により、この内部の圧力の変動による浮沈子の浮沈挙動を利用して内溶液の温度状態を、容器外部から一目で知ることができる。また、浮沈子は直接内容液に浸漬しているので内容液の温度を正確にモニターすることができる。   In the sealed container containing the contents liquid, the gas present on the liquid surface expands or contracts depending on the temperature of the contents liquid, and the pressure in the container body varies. The temperature state of the inner solution can be known at a glance from the outside of the container using the floating behavior of the floating sediment due to the fluctuation of the internal pressure. Further, since the float is immersed directly in the content liquid, the temperature of the content liquid can be accurately monitored.

請求項3記載の発明の手段は、請求項2記載の発明において、浮沈子が、常温で底部に沈降し、所定温度への低下に伴う減圧により液面に浮上する構成とすること、にある。   According to a third aspect of the present invention, in the second aspect of the invention, the floated sediment settles on the bottom at room temperature and floats on the liquid surface due to the reduced pressure accompanying a decrease to a predetermined temperature. .

請求項3記載の上記構成により、浮沈子が液面に浮上していることを見て、たとえば内容液が飲料であれば、飲み頃の温度に冷えていることを一目で知ることができる。   According to the above-described configuration of the third aspect, it is possible to know at a glance that the floating liquid has floated on the liquid surface and, for example, if the content liquid is a beverage, it is cooled to the temperature at which it is drunk.

請求項4記載の発明の手段は、請求項2記載の発明において、浮沈子が、常温で液面に浮上し、所定温度への上昇に伴う加圧により底部に沈降する構成とすること、にある。   According to a fourth aspect of the present invention, in the invention of the second aspect, the floating siding floats on the liquid surface at room temperature and sinks to the bottom by pressurization accompanying a rise to a predetermined temperature. is there.

請求項4記載の上記構成により、浮沈子が底部に沈降していることを見て、たとえば内容液が飲料であれば、飲み頃の温度に温まっていることを一目で知ることができる。   According to the above-described configuration of the fourth aspect, it can be seen at a glance that the floating liquid is sinking to the bottom, and, for example, if the content liquid is a beverage, it is warmed to the temperature of drinking.

請求項5〜7に係る発明は不正開放防止の有無を認識するための、すなわち内容液の密閉状態に係る表示機能に関し、請求項5記載の発明の手段は、請求項1、2、3または4記載の発明において、容器本体の密閉状態の開放に伴う内部の圧力変化により、浮沈子が浮上あるいは沈降する構成とし、この浮沈子の位置により不正開放の有無が認識できるようにすること、にある。   The invention according to claims 5 to 7 relates to a display function for recognizing the presence or absence of unauthorized opening prevention, that is, according to the sealed state of the content liquid. In the invention described in 4, the floating body is caused to rise or sink due to the internal pressure change accompanying the opening of the container body in a sealed state, and the presence or absence of unauthorized opening can be recognized by the position of the floating body. is there.

請求項5記載の上記構成により、密閉した容器を開放すると容器本体内の圧力が外気圧と同一になるまで変化するので、この変化に応じて浮沈子を浮上あるいは沈降させることができ、この浮沈子の位置により一目で不正開放の有無を知ることができる。   When the sealed container is opened, the pressure in the container body changes until it becomes the same as the external atmospheric pressure, so that the float can float or sink according to this change. The presence or absence of unauthorized opening can be known at a glance according to the position of the child.

請求項6記載の発明の手段は、請求項5記載の発明において、内容液を収納した常温密閉状態において、内部が大気圧に対して減圧状態となる用途に使用される容器であること、浮沈子が、この常温密閉状態で液面に浮上した状態にあり、また密封状態の開放に伴う内圧の上昇により底部に沈降する構成とすること、にある。   According to a sixth aspect of the present invention, in the fifth aspect of the invention, the container according to the fifth aspect of the present invention is a container that is used for an application in which the inside is depressurized with respect to atmospheric pressure in a sealed state at room temperature containing the content liquid. The child is in a state of floating on the liquid surface in the sealed state at room temperature, and is configured to sink to the bottom due to an increase in internal pressure accompanying the opening of the sealed state.

たとえばポリエチレンテレフタレート(以下PETと記す。)樹脂製の、2軸延伸ブロー成形ボトルは殺菌を必要とするたとえば果汁飲料、お茶等の内容液を90℃程度の高温で充填する所謂高温充填向け用途に使用され、90℃前後の温度で内容液をボトルに充填し、キャップをして密封後常温、あるいは冷却した状態ではボトル内がかなりの減圧状態となるが、請求項6記載の上記構成により、このような内部が大気圧に対して減圧状態となる用途に使用される容器では、その密閉状態を開放すると容器本体内の圧力が大気圧にまで上昇するので、液面に浮上していた浮沈子を、底部に沈降した状態とすることができ、この浮沈子の位置により一目で不正開放の有無を知ることができる。   For example, a biaxial stretch blow molded bottle made of polyethylene terephthalate (hereinafter referred to as “PET”) resin is used for so-called high temperature filling that fills liquids such as fruit juice and tea that require sterilization at a high temperature of about 90 ° C. The bottle is filled with the content liquid at a temperature of around 90 ° C., sealed with a cap at room temperature, or in a cooled state, the bottle is in a considerably depressurized state. In containers that are used for applications where the inside is depressurized with respect to atmospheric pressure, when the sealed state is opened, the pressure in the container body rises to atmospheric pressure, so The child can be in a state of sinking to the bottom, and the presence or absence of unauthorized opening can be known at a glance by the position of the floating child.

請求項7記載の発明の手段は、請求項5記載の発明において、内容液を収納した常温密閉状態において、内部が大気圧に対して加圧状態となる用途に使用される容器であること、この常温密閉状態で浮沈子が、底部に沈降した状態にあり、密封状態の開放に伴う内圧の下降により液面に浮上する構成とすること、にある。   The means of the invention according to claim 7 is the container used in the invention according to claim 5, wherein the container is used for an application in which the inside is pressurized with respect to atmospheric pressure in a sealed state at room temperature containing the content liquid. The floating scuttle is in a state of sinking to the bottom in a sealed state at room temperature, and is configured to float on the liquid level due to a decrease in internal pressure accompanying the opening of the sealed state.

たとえば炭酸成分を含有する内容液を収納する容器等、内部が大気圧に対して加圧状態となる用途に使用される容器では、その密閉状態を開放すると容器本体内の圧力が大気圧にまで下降するので、請求項7記載の上記構成により底部に沈降していた浮沈子を、液面に浮上した状態とすることができ、この浮沈子の位置により一目で不正開放の有無を知ることができる。   For example, in a container that is used for applications where the inside is pressurized with respect to atmospheric pressure, such as a container that contains a liquid containing a carbonic acid component, the pressure inside the container body reaches atmospheric pressure when the sealed state is opened. Since it descends, the floating sunk settled at the bottom by the above-described configuration of claim 7 can be brought to a state where it floated on the liquid surface, and the presence or absence of unauthorized opening can be known at a glance by the position of this floating scuttle. it can.

請求項8記載の発明の手段は、請求項1、2、3、4、5、6または7記載の発明において、浮沈子を、加飾あるいは表示のための補助部材を付設したものとすること、にある。   The invention according to claim 8 is the invention according to claim 1, 2, 3, 4, 5, 6 or 7, wherein the float is attached with an auxiliary member for decoration or display. ,It is in.

請求項8記載の上記構成により、補助部材により浮沈子の位置をより明確に知ることができ、表示機能をより効果的に現出させることができる。また補助部材により、容器の装飾効果、あるいはアイキャッチ効果をより効果的に達成することもできる。   According to the above-described configuration, the position of the floating child can be known more clearly by the auxiliary member, and the display function can be more effectively revealed. In addition, the auxiliary member can more effectively achieve the decorative effect of the container or the eye catching effect.

本発明は上記した方法であり、以下に示す効果を奏する。
請求項1記載の発明にあっては、容器本体中の内容液の圧力状態は、内容液を充填し閉栓した後の内容液の温度変化、内容液からの揮発成分の量、内容液の密閉状態等により変化するので、浮沈子に作用する浮力と重力のバランスを適宜設計することにより、この浮沈子により容器本体内の圧力状態を介して、内容液の状態を知らせる表示機能(モニター機能、あるいはインジケータ機能とも云える。)を発揮させることができる。
The present invention is the method described above, and has the following effects.
In the first aspect of the invention, the pressure state of the content liquid in the container body is the temperature change of the content liquid after filling and closing the content liquid, the amount of volatile components from the content liquid, and the sealing of the content liquid. Because it changes depending on the state, etc., by appropriately designing the balance between buoyancy and gravity acting on the float, the display function that informs the state of the liquid content via the pressure state in the container body (monitor function, Or it can also be said to be an indicator function.).

請求項5記載の発明にあっては、密閉した容器を開放すると容器本体内の圧力が外気圧と同一になるまで変化するので、この変化に応じて浮沈子を浮上あるいは沈降させることができ、この浮沈子の位置により一目で不正開放の有無を知ることができる。   In the invention of claim 5, when the sealed container is opened, the pressure in the container body changes until it becomes equal to the external pressure, so that the floating slat can be levitated or settled according to this change, The presence or absence of unauthorized opening can be known at a glance from the position of the float.

請求項6記載の発明にあっては、高温充填を必要とする内容液を収納する容器等、常温で減圧状態となる容器では、その密閉状態を開放すると容器本体内の圧力が大気圧にまで上昇するので、液面に浮上していた浮沈子を、底部に沈降した状態とすることができ、この浮沈子の位置により一目で不正開放の有無を知ることができる。   In the invention according to claim 6, in a container that is in a decompressed state at room temperature, such as a container that contains a liquid content that requires high-temperature filling, the pressure in the container body reaches atmospheric pressure when the sealed state is opened.

以下本発明の実施の形態を図面を参照しながら説明する。
図1及び図2は本発明の液体収納容器の第1実施例を説明するものである。
図1は容器の正面図で、PET樹脂製の2軸延伸ブローボトルである透明な容器本体1は円筒状の胴部4を有し、この容器本体1に浮沈子11を入れて、さらに透明な飲料である内容液Lを充填し、口筒部3にキャップ6を螺合して密閉した状態である。そして図1(a)は浮沈子11が底部5に沈降した状態、図1(b)は液面LSに浮上した状態を示している。
Embodiments of the present invention will be described below with reference to the drawings.
1 and 2 illustrate a first embodiment of the liquid container according to the present invention.
FIG. 1 is a front view of a container, and a transparent container body 1 which is a biaxially stretched blow bottle made of PET resin has a cylindrical body portion 4. It is in a state in which the content liquid L, which is a simple beverage, is filled and the cap 6 is screwed into the mouth tube portion 3 and sealed. FIG. 1A shows a state where the float 11 has settled on the bottom 5, and FIG. 1B shows a state where the float 11 floats on the liquid level LS.

図2は図1の容器に使用している浮沈子11の(a)は正面図、(b)は縦断面図である。この浮沈子11は魚の形をした低密度ポリエチレン樹脂製の中空成形品と金属製の錘13からなる。中空成形品は胴部11aと口部11bを有し、口部11bの先端は開口端12となっており、この口部11bの外周にリング状の錘13が取り付けられている。   2A is a front view, and FIG. 2B is a longitudinal cross-sectional view of the float 11 used in the container of FIG. The float 11 is composed of a fish-shaped hollow molded product made of low density polyethylene resin and a metal weight 13. The hollow molded article has a body portion 11a and a mouth portion 11b, the tip of the mouth portion 11b is an open end 12, and a ring-shaped weight 13 is attached to the outer periphery of the mouth portion 11b.

この浮沈子11の中には、容器本体1内の圧力の大きさに応じた量の内容液Lが進入しており、液面LSf上の空間Rの大きさに応じた浮力が浮沈子11に作用する(図2(b)参照)。そしてこの浮力と、浮沈子11に作用する重力のバランスによって浮沈子11は内容液L中で浮上したり、沈降したりする。
さらに、容器本体1を密閉した状態で内部の圧力が上がると、浮沈子11の口部11b開口端12より内容液Lが胴部11a内に更に進入し、液面LSfが上昇し、空間Rが小さくなり、浮力が小さくなる。逆に圧力が下がると内容液Lが流出し、液面LSfが下降し空間Rが大きくなり、浮力が大きくなる。
The content liquid L in an amount corresponding to the magnitude of the pressure in the container main body 1 enters the float 11 and the buoyancy according to the size of the space R on the liquid level LSf is increased. (See FIG. 2B). Then, the float 11 sinks or sinks in the content liquid L by the balance between this buoyancy and the gravity acting on the float 11.
Further, when the internal pressure rises with the container body 1 sealed, the content liquid L further enters the body 11a from the mouth 11b open end 12 of the float 11 and the liquid level LSf rises, and the space R Becomes smaller and buoyancy becomes smaller. Conversely, when the pressure is reduced, the content liquid L flows out, the liquid level LSf is lowered, the space R is increased, and the buoyancy is increased.

また、浮沈子11に取り付ける錘13は金属製等の内容液Lよりも比重の大きいものが使用され、この錘13により浮沈子11の重力を調整すると共に、浮沈子11が内容液L中で、開口端12を下端とした起立状態で浮沈姿勢を保つための機能を果たす。   Moreover, the weight 13 attached to the float / sink 11 has a specific gravity larger than that of the content liquid L made of metal or the like. The weight 13 adjusts the gravity of the float / sink 11 and the float / sink 11 is contained in the content liquid L. It fulfills the function of maintaining the up and down posture in the standing state with the open end 12 as the lower end.

本実施例の容器は、浮沈子11が内容液Lの温度状態に係る表示機能(モニター機能)を発揮するようにしたものであり、作用する重力と浮力を考慮して設計することにより、この浮沈子11は常温では底部5に沈降した状態にあり(図1(a)の状態)、内容液Lが5℃程度の飲み頃になった際に、液面LSにまで浮上(図1(b)の状態)するようにしている。   The container of the present embodiment is such that the float and sink 11 exhibits a display function (monitor function) related to the temperature state of the content liquid L, and is designed by taking into account the acting gravity and buoyancy. The float 11 is in a state of sinking to the bottom 5 at room temperature (the state of FIG. 1A), and when the content liquid L is about 5 ° C., it floats to the liquid level LS (FIG. 1 ( b)).

内容液Lを常温で充填して密閉した容器を密閉したまま冷蔵庫等に入れて冷却すると、内容液Lが収縮すると共に、特に液面LS上に存在する気体が収縮して容器本体内の圧力が下降し、その結果浮沈子11に作用する浮力が増大して、浮沈子11が浮上する。
そして、販売者、あるいは消費者は浮沈子11が浮上しているのも見て、一目で飲料が飲み頃にまで冷えていることを知ることができる。
When the sealed container filled with the liquid L at room temperature is placed in a refrigerator or the like and cooled, the liquid L shrinks, and in particular, the gas present on the liquid level LS contracts and the pressure inside the container body As a result, the buoyancy acting on the float / sink 11 increases and the float / sink 11 rises.
Then, the seller or the consumer can also see that the float 11 is rising, and can know at a glance that the beverage is cold enough to drink.

ここで、容器本体1の胴部4を可撓性のあるものとしておけば、胴部4を押圧すると容器本体1内部の圧力が上昇するので、たとえば図1(b)のように密閉して浮沈子11が液面Lに浮上した状態で、胴部4を手で掴んで押圧すると浮沈子11は沈降し、さらにこの押圧を解除すると浮沈子がまた浮上するため、使用者はこの浮沈子11の上下動を楽しむこともできる。   Here, if the body part 4 of the container body 1 is made flexible, the pressure inside the container body 1 rises when the body part 4 is pressed. For example, as shown in FIG. In the state where the float 11 has floated on the liquid level L, if the body part 4 is grasped and pressed by hand, the float 11 will sink, and if the pressure is released, the float will float again. You can also enjoy 11 vertical movements.

次に、図3は本発明の液体収納容器の第2実施例を示す正面図であり、(a)は浮沈子11が底部5に沈降した状態、(b)は液面LSに浮上した状態を示す。
本実施例の容器の使用目的、およびその基本的な構成は第1実施例と同様であるが、浮沈子11を、上端部に補助部材14として「冷えています」という文字を印刷した表示プレートを付設したものとすると共に、透明な基材フィルムに所定の高さ範囲に亘ってグラデーション状にベタ印刷したシュリンクフィルム15を胴部4に外装することにより、浮沈子11の内容液Lの温度に係る表示機能を、よりアイキャッチ効果が発揮されるようにしたものである。
本実施例のように「冷えています」等の文字を入れておけば浮沈子11による内容液の状態に係る表示機能をより効果的にすることがきる。
Next, FIG. 3 is a front view showing a second embodiment of the liquid container according to the present invention, in which (a) shows a state in which the float 11 has settled on the bottom 5, and (b) shows a state in which the float has floated on the liquid level LS. Indicates.
The purpose of use of the container of the present embodiment and the basic configuration thereof are the same as those of the first embodiment, but the display plate on which the characters “cold” is printed as the auxiliary member 14 on the upper end portion of the float 11 The temperature of the liquid L in the float 11 is covered by covering the body 4 with a shrink film 15 solidly printed in gradation over a predetermined height range on a transparent base film. In the display function according to the above, the eye-catching effect is further exhibited.
If a character such as “I am cold” is entered as in the present embodiment, the display function related to the state of the liquid content by the float 11 can be made more effective.

図3(a)に図示されるように、常温で浮沈子11が底部5に沈降した状態で、表示プレート14はシュリンクフィルム15のベタ印刷部15aに隠れて外部から見辛い状態であるが(図3(a)参照)、内容液Lの冷却が進行して浮上すると、表示プレート14の「冷えています」という文字がはっきり見えるようになる(図3(b)参照)。   As shown in FIG. 3A, the display plate 14 is hidden by the solid printing portion 15a of the shrink film 15 and is difficult to see from the outside in a state where the float 11 is settled on the bottom 5 at room temperature ( When the cooling of the content liquid L proceeds and the surface of the liquid L rises, the word “cooled” on the display plate 14 becomes clearly visible (see FIG. 3B).

ここで、実施例1および実施例2では、浮沈子11の浮上により内容液Lの温度状態に係る表示機能を発揮させる例を説明したが、逆に浮沈子11が常温で液面LSに浮上しているようにして、所定温度への上昇に伴う容器本体1内の加圧により底部5に沈降する構成とすることもでき、浮沈子11が底部5に沈降していることを見て、たとえば内容液Lが飲料であれば、飲み頃の温度に温まっていることを一目で知ることができる。   Here, in the first embodiment and the second embodiment, the example in which the display function related to the temperature state of the content liquid L is demonstrated by the floating of the floating sunk 11, but conversely, the floating slid 11 floats on the liquid level LS at room temperature. Thus, it can be configured to settle to the bottom 5 by pressurization in the container body 1 accompanying the rise to a predetermined temperature, seeing that the float 11 is settled to the bottom 5, For example, if the content liquid L is a beverage, it can be known at a glance that it is warmed to the temperature at which it is drunk.

次に、図4は本発明の液体収納容器の第3実施例を示す正面図であり、(a)は浮沈子11が液面LSに浮上した状態、(b)はキャップ6を外して浮沈子11が底部5に沈降した状態を示し、本実施例に使用する容器本体1は第1実施例に使用されたものと同一である。   Next, FIG. 4 is a front view showing a third embodiment of the liquid container according to the present invention, where (a) shows a state in which the float 11 has floated on the liquid level LS, and (b) shows that the cap 6 has been removed and floated. A state in which the child 11 sinks to the bottom 5 is shown, and the container body 1 used in this embodiment is the same as that used in the first embodiment.

本実施例の容器は、浮沈子11の高さ位置によって不正開放の有無を確認できるようにした例、すなわち内容液Lの密閉状態に係る表示機能を発揮させるものである。たとえば高温充填を必要とするジュース等を収納する容器では、常温密閉状態において、内部が大気圧に対して減圧状態となるが、この状態で浮沈子11を液面LSに浮上した状態とし(図1(a)の状態)、キャップ6を外すと密閉状態の開放に伴い容器本体1内の圧力が上昇して底部に沈降した状態となる(図1(b)の状態)ようにすることができ、この浮沈子11の位置により不正開放の有無、すなわち内容液Lの密閉状態を知ることができる。   The container of the present embodiment is an example in which the presence or absence of unauthorized opening can be confirmed by the height position of the float 11, that is, the display function related to the sealed state of the content liquid L is exhibited. For example, in a container for storing juice or the like that requires high-temperature filling, the inside is in a depressurized state with respect to atmospheric pressure in a sealed state at room temperature. In this state, the float 11 is floated on the liquid level LS (see FIG. 1 (a)), when the cap 6 is removed, the pressure in the container body 1 rises with the opening of the sealed state, and the bottom of the container is settled (state shown in FIG. 1 (b)). The presence or absence of unauthorized opening, that is, the sealed state of the content liquid L can be known from the position of the float 11.

一方、逆に炭酸成分を含有する内容液Lを収納する容器では、常温密閉状態において、内部が大気圧に対して加圧状態となるが、この場合には浮沈子11を常温密閉状態で底部5に沈降させた状態とし、キャップ6を外すと密封状態の開放に伴い容器本体1内の圧力が下降して液面LSに浮上した状態とすることができ、この場合も浮沈子11の位置により不正開放の有無を知ることができる。   On the other hand, in the container for storing the content liquid L containing the carbonic acid component, the inside is pressurized with respect to atmospheric pressure in a sealed state at room temperature. In this case, the float 11 is sealed in the sealed state at room temperature. 5, and when the cap 6 is removed, the pressure in the container main body 1 drops and floats on the liquid level LS when the sealed state is opened. In this case as well, the position of the float 11 By this, it is possible to know the presence or absence of unauthorized opening.
