Description

本発明は携帯用飲料容器に関し、より詳細には保温性に優れた携帯用飲料容器に関するものである。   The present invention relates to a portable beverage container, and more particularly to a portable beverage container excellent in heat retention.

清涼飲料水やお茶、コーヒなどの飲料液体を保温する携帯用の飲料容器としてはこれまでいわゆる魔法瓶が広く使用されてきた。魔法瓶は二重容器の間を真空にし、内瓶の外周面をメッキなどによって鏡面とすることによって、対流や伝導、熱輻射による熱移動を抑えて断熱性を高めたものである。   So-called thermos bottles have been widely used so far as portable beverage containers for keeping beverage liquids such as soft drinks, tea and coffee. A thermos bottle has a vacuum between the two containers, and the outer peripheral surface of the inner bottle is made into a mirror surface by plating or the like, thereby suppressing heat transfer due to convection, conduction, and heat radiation, thereby improving heat insulation.

このような構造の魔法瓶は保温性に優れたものであるが、ガラスやステンレスなどの材料を用いているので重く、また円柱形状をしているので鞄などにいれると嵩張るという欠点があった。また魔法瓶の、飲料液体を入れる内容器は取り外しができないので、飲料液体を内容器ごと冷やしたり温めたりすることができなかった。このため、冷やした又は温めた飲料液体を魔法瓶の内容器に注ぎ入れていた。   The thermos with such a structure is excellent in heat retention, but it is heavy because it uses a material such as glass or stainless steel, and has a drawback that it is bulky because it has a cylindrical shape and is placed in a basket. In addition, since the inner container for storing the beverage liquid in the thermos cannot be removed, the beverage liquid could not be cooled or warmed together with the inner container. For this reason, the cold or warm drink liquid was poured into the inner container of the thermos.

一方、飲料液体の入ったペットボトルの販売量が近年急激に増加している。この飲料液体の入ったペットボトルを、中綿の入った布やアルミ蒸着フィルムを貼り合わせた不織布からなる保温カバーで被覆して水筒代わりに携帯することが広く行われている。このような構成によれば従来の魔法瓶に比べて軽く携帯性に優れるものの、上記保温カバーでは高い断熱効果は得られないため、数時間も経てばペットボトル内の飲料液体は常温となる。   On the other hand, the sales volume of plastic bottles containing beverage liquids has increased rapidly in recent years. It has been widely practiced to carry this plastic bottle containing a beverage liquid instead of a water bottle by covering it with a heat insulating cover made of a non-woven fabric bonded with a cloth containing a batting or an aluminum vapor deposition film. According to such a structure, although it is light and excellent in portability as compared with a conventional thermos bottle, a high heat insulating effect cannot be obtained with the above-mentioned heat insulating cover, so that the beverage liquid in the PET bottle becomes room temperature after several hours.

そこで、保温性を向上させた保温カバーがこれまでから種々提案されている。例えば特許文献１では、内周面に断熱材を装着したボックスと、ボックス上部に着脱自在に外嵌するコップ型の外蓋とを備え、ペットボトルをボックス内に収納した状態で外蓋を外して飲料液体を注げるようにした保温具が提案されている。また特許文献２では、ガスバリヤ性フィルム内に芯材を減圧封入した真空断熱部材で側周面を断熱し、蓋部と底部を発泡樹脂で断熱する携帯用ペットボトル収納容器が提案されている。さらに特許文献３では、保温材を充填した、飲料容器を収納する中容器と、中容器の外周を覆う断熱性の外容器とを備えた携帯性のある保温用容器が提案されている。
特開平７−１４９３７９号公報 特開２００６−１２４０１３号公報 特開２０００−８５８５９号公報 Therefore, various heat insulating covers with improved heat insulating properties have been proposed so far. For example, in Patent Document 1, a box having a heat insulating material attached to the inner peripheral surface and a cup-type outer lid that is detachably fitted to the upper portion of the box, and the outer lid is removed while the plastic bottle is stored in the box. Heat insulators that can pour beverage liquids have been proposed. Patent Document 2 proposes a portable plastic bottle storage container in which a side peripheral surface is thermally insulated with a vacuum heat insulating member in which a core material is sealed in a gas barrier film, and a lid and a bottom are thermally insulated with foamed resin. Further, Patent Document 3 proposes a portable heat retaining container including a middle container that contains a heat retaining material and that contains a beverage container and a heat insulating outer container that covers the outer periphery of the middle container.

しかしながら、上記提案のいずれの保温容器も繰り返し使用されるものの、ペットボトルは中身の飲料液体が無くなると通常は廃棄される。廃棄されたペットボトルの一部は溶融・再加工されて再利用されるが、環境問題の点からは飲料液体が入れられる容器も廃棄せずに繰り返し使用できるものが望ましい。   However, although any of the above-described heat insulation containers are used repeatedly, the PET bottle is usually discarded when the beverage liquid in the bottle is exhausted. A part of the discarded plastic bottle is melted, reprocessed and reused. From the viewpoint of environmental problems, it is desirable that the container in which the beverage liquid is put can be repeatedly used without being discarded.

本発明はこのような従来の問題に鑑みてなされたものであり、その目的とするところは、軽量で携帯性に優れ、高い保温性を有し、しかも飲料液体が入った内容器を捨てることなく繰り返し使用できる携帯用飲料容器を提供することにある。   The present invention has been made in view of such conventional problems. The object of the present invention is to dispose of an inner container that is lightweight, excellent in portability, has high heat retention properties, and contains beverage liquid. An object of the present invention is to provide a portable beverage container that can be used repeatedly.

また本発明の目的は、液体飲料を内容器ごと冷却および加温できる携帯用飲料容器を提供することにある。   Moreover, the objective of this invention is providing the portable drink container which can cool and heat a liquid drink with an inner container.

さらに本発明の目的は、鞄などに入れても嵩張らない携帯用飲料容器を提案することにある。   A further object of the present invention is to propose a portable beverage container that is not bulky even when placed in a bag or the like.

前記目的を達成するため本発明の携帯用飲料容器は、飲料液体を入れる上面開口の内容器と、この内容器を着脱可能に収納する上面開口の外ケースとを備え、飲料液体の飲み口が形成された蓋部材が内容器の上面開口を密封するとともに、外ケースの上面開口に係止する構成とした。   In order to achieve the above object, a portable beverage container of the present invention comprises an inner container having an upper surface opening for containing a beverage liquid and an outer case having an upper surface opening for detachably storing the inner container. The formed lid member hermetically seals the upper surface opening of the inner container and engages with the upper surface opening of the outer case.

ここで、軽量性と保温性を同時に具備させる観点から、前記外ケースの内周面および前記内容器の外周面の少なくとも一方に突起を形成し、前記内容器を前記外ケースに装着すると、前記外ケースの内周面と前記内容器の外周面との間に空隙が形成されるようにするのが好ましい。さらには前記内容器の外周面上部に、前記空隙の幅以上の高さの突条を形成し、前記内容器を前記外ケースに装着すると、前記突条によって前記空隙の開口が密封されるようにするのが好ましい。   Here, from the viewpoint of providing light weight and heat retaining properties at the same time, forming a protrusion on at least one of the inner peripheral surface of the outer case and the outer peripheral surface of the inner container, and mounting the inner container to the outer case, It is preferable that a gap is formed between the inner peripheral surface of the outer case and the outer peripheral surface of the inner container. Furthermore, a protrusion having a height higher than the width of the gap is formed on the outer peripheral surface of the inner container. When the inner container is mounted on the outer case, the opening of the gap is sealed by the protrusion. Is preferable.

保温性のみならず飲料液体を積極的に冷却及び加温する観点から、前記空隙に、冷却剤又は加温剤を出し入れ可能に収納できる空間を形成してもよい。   From the viewpoint of positively cooling and warming the beverage liquid as well as the heat retaining property, a space in which the coolant or the warming agent can be taken in and out can be formed in the gap.

鞄などへの収納性を向上させる観点から、前記内容器および前記外ケースの形状を幅の薄い略直方体形状とするのが好ましい。   From the viewpoint of improving storage in a bag or the like, it is preferable that the inner container and the outer case have a substantially rectangular parallelepiped shape with a small width.

本発明の携帯用飲料容器では、飲料液体を入れる上面開口の内容器と、この内容器を着脱可能に収納する上面開口の外ケースとを備え、飲料液体の飲み口が形成された蓋部材が内容器の上面開口を密封するとともに、外ケースの上面開口に係止する構成としたので、部品点数が少なくなり軽量で携帯性に優れ、また飲料液体が入った内容器を捨てることなく繰り返し使用できる。   In the portable beverage container of the present invention, there is provided a lid member having an inner container having an upper surface opening for containing a beverage liquid and an outer case having an upper surface opening for detachably storing the inner container, and having a drinking liquid drinking mouth formed therein. The upper opening of the inner container is sealed and the upper case is locked to the upper opening of the outer case, so the number of parts is reduced, it is lightweight and excellent in portability, and the inner container containing beverage liquid can be used repeatedly without being discarded. it can.

前記外ケースの内周面および前記内容器の外周面の少なくとも一方に突起を形成し、前記内容器を前記外ケースに装着したときに、前記外ケースの内周面と前記内容器の外周面との間に空隙が形成されるようにすると、前記空隙によって外ケースと内容器の間の熱伝導による熱移動が遮断され保温性が向上する。また魔法瓶等に比べて構造が簡単であるため軽量化が図れて携帯性に優れる。さらに前記内容器の外周面上部に、前記空隙の幅以上の高さの突条を形成し、前記内容器を前記外ケースに装着したときに、前記突条によって前記空隙の開口が密封されるようにすると保温性がさらに向上する。また前記空隙に、冷却剤又は加温剤を出し入れ可能に収納できる空間を形成すると、その空間に冷却剤又は加温剤を装着することによって飲料液体を積極的に冷却又は加温できるようになる。   A protrusion is formed on at least one of the inner peripheral surface of the outer case and the outer peripheral surface of the inner container, and when the inner container is mounted on the outer case, the inner peripheral surface of the outer case and the outer peripheral surface of the inner container When a gap is formed between the outer case and the inner case, heat transfer due to heat conduction between the outer case and the inner container is blocked by the gap, thereby improving heat retention. In addition, since the structure is simpler than a thermos bottle, the weight can be reduced and the portability is excellent. Further, a protrusion having a height greater than or equal to the width of the gap is formed on the outer peripheral surface of the inner container, and the opening of the gap is sealed by the protrusion when the inner container is attached to the outer case. By doing so, the heat retention is further improved. In addition, when a space in which the coolant or the warming agent can be stored in and out is formed in the gap, the beverage liquid can be actively cooled or warmed by mounting the coolant or the warming agent in the space. .

前記内容器および前記外ケースの形状を幅の薄い略直方体形状とすると、鞄などへの収納性が格段に向上する。   When the shape of the inner container and the outer case is a substantially rectangular parallelepiped shape having a small width, the storability in a bag or the like is remarkably improved.

以下、本発明に係る携帯用飲料容器について図に基づいて説明するが、本発明はこれらの実施形態に何ら限定されるものではない。   Hereinafter, although the portable drink container concerning the present invention is explained based on a figure, the present invention is not limited to these embodiments at all.

図１は本発明に係る携帯用飲料容器（以下、「飲料容器」と記すことがある）の一実施形態を示す斜視図である。図１の飲料容器は、飲料液体を入れる薄い箱形状の上面開口で中空の内容器１と、内容器１を着脱可能に収納する上面開口で中空の外ケース２と、内容器１の上面開口１１を密閉し且つ外ケース２の上面開口２１に係止する蓋部材３とを備える。   FIG. 1 is a perspective view showing an embodiment of a portable beverage container (hereinafter sometimes referred to as “beverage container”) according to the present invention. The beverage container shown in FIG. 1 has a thin box-shaped top opening for containing a beverage liquid, a hollow inner container 1, a hollow outer case 2 for detachably storing the inner container 1, and a top opening of the inner container 1. 11 and a lid member 3 that is engaged with the upper surface opening 21 of the outer case 2.

内容器１の外周面下部には、横方向に所定間隔で複数個の突起１２が形成されている。これらの突起１２によって外ケース２と内容器１との間に空隙が安定して確実に形成されるようになる。また内容器１の外周面には、横方向および縦方向に複数のリブ１３ａ，１３ｂが形成されている。これらのリブ１３ａ，１３ｂによって、内容器１に貯溜された飲料液体（不図示）が膨張・収縮した場合でも内容器１の変形が小さく抑えられるようになる。そしたまた内容器１の外周面上部には横方向に突条１４が周設されている。さらにこの突条１４の上部には一組の係止部（図１では一方のみ図示）１５が形成されている。後述するように、突条１４によって内容器１と外ケース２との間に形成される空隙の上部開口が密封され、また蓋部材３の内フラップ５ａの係止爪５１（図３に図示）が内容器１の係止部１５に係合することによって、内容器１の上面開口１１を密封するように蓋部材３が内容器１に固定する。   A plurality of protrusions 12 are formed at predetermined intervals in the lateral direction at the lower portion of the outer peripheral surface of the inner container 1. By these protrusions 12, a gap is stably and reliably formed between the outer case 2 and the inner container 1. A plurality of ribs 13a and 13b are formed on the outer peripheral surface of the inner container 1 in the horizontal direction and the vertical direction. By these ribs 13a and 13b, even when a beverage liquid (not shown) stored in the inner container 1 expands and contracts, deformation of the inner container 1 can be suppressed to a small level. In addition, a protrusion 14 is provided in the lateral direction on the outer peripheral surface of the inner container 1. Further, a set of locking portions (only one is shown in FIG. 1) 15 is formed on the upper portion of the protrusion 14. As will be described later, the upper opening of the gap formed between the inner container 1 and the outer case 2 is sealed by the protrusion 14, and the locking claw 51 of the inner flap 5a of the lid member 3 (shown in FIG. 3). The lid member 3 is fixed to the inner container 1 so as to seal the upper surface opening 11 of the inner container 1 by engaging the engaging portion 15 of the inner container 1.

一方、蓋部材３の上面から垂直に円筒部３１が延出し、円筒部３１の上面開口が飲み口３２（図２に図示）となっている。円筒部３１の外周面には雄ネジ３５（図２に図示）が形成されており、ここに、内周面に雌ネジ４１（図２に図示）が形成された下面開口の円筒状のキャップ４が螺着して飲み口３２が封止されている。また蓋部材３の側面の、内容器１の係止部１５および外ケース２の係止部２３ａ，２３ｂと対応する位置に、それぞれ一対の内フラップ５ａと外フラップ６ａが回動可能に取り付けられている。具体的には、蓋部材３の側面に横方向に離隔して２つの突部３４ａ，３４ｂが形成され、この２つの突部３４ａ，３４ｂの内方に内フラップ５ａが回動可能に軸支されている。そして、内フラップ５ａの外側を囲むように略Ｕ字状の外フラップ６ａが２つの突部３４ａ，３４ｂの外方に回動可能に軸支されている。蓋部材３の内容器１及び外ケース２への取り付けについては後述する。   On the other hand, the cylindrical portion 31 extends vertically from the upper surface of the lid member 3, and the upper surface opening of the cylindrical portion 31 is a drinking mouth 32 (shown in FIG. 2). A male screw 35 (shown in FIG. 2) is formed on the outer peripheral surface of the cylindrical portion 31, and a cylindrical cap having a lower surface opening in which a female screw 41 (shown in FIG. 2) is formed on the inner peripheral surface. 4 is screwed and the drinking mouth 32 is sealed. A pair of inner flaps 5a and outer flaps 6a are rotatably attached to the side surfaces of the lid member 3 at positions corresponding to the locking portions 15 of the inner container 1 and the locking portions 23a and 23b of the outer case 2, respectively. ing. Specifically, two protrusions 34a and 34b are formed on the side surface of the lid member 3 so as to be laterally separated from each other, and the inner flap 5a is pivotally supported inwardly of the two protrusions 34a and 34b. Has been. A substantially U-shaped outer flap 6a is pivotally supported on the outside of the two protrusions 34a and 34b so as to surround the outer side of the inner flap 5a. The attachment of the lid member 3 to the inner container 1 and the outer case 2 will be described later.

外ケース２は内容器１を着脱可能に収納するため、その上面開口２１の内形は、内容器１の外形と相似形状で内容器１の突起１２の高さ分だけ大きく形成されている。また外ケース２の内底面には、内容器１を装着したときに内容器１の底部が当接する突起２２が形成されている。この突起２２によって内容器１と外ケース２との間に形成される空隙が安定且つ確実に保持されるようになる。またこの突起２２によって形成される内容器１と外ケース２との間の空間は、冷却剤７又は加温剤７を収納する空間としても利用される。外ケース２の外周面上部には、内容器１の係止部１５の幅よりも広く隔てて一対の係止部２３ａ，２３ｂが形成され、外ケース２の上面開口２１を隔てた向かい側にも同様に一対の係止部（不図示）が同様に形成されている。後述するように、蓋部材３の外フラップ６ａの係止爪６１ａ，６１ｂ（図５参照）が外ケース２の係止部２３ａ，２３ｂに係合することによって、外ケース２の上面開口２１に蓋部材３が固定される。   Since the outer case 2 detachably accommodates the inner container 1, the inner shape of the upper surface opening 21 is similar to the outer shape of the inner container 1 and is formed to be larger by the height of the protrusion 12 of the inner container 1. A projection 22 is formed on the inner bottom surface of the outer case 2 so that the bottom of the inner container 1 contacts when the inner container 1 is mounted. By this protrusion 22, a gap formed between the inner container 1 and the outer case 2 can be stably and reliably held. The space between the inner container 1 and the outer case 2 formed by the protrusions 22 is also used as a space for storing the coolant 7 or the warming agent 7. A pair of locking portions 23 a and 23 b are formed on the outer peripheral surface of the outer case 2 so as to be wider than the width of the locking portion 15 of the inner container 1, and also on the opposite side of the outer case 2 across the upper surface opening 21. Similarly, a pair of locking portions (not shown) are similarly formed. As will be described later, the engaging claws 61 a and 61 b (see FIG. 5) of the outer flap 6 a of the lid member 3 engage with the engaging portions 23 a and 23 b of the outer case 2. The lid member 3 is fixed.

図２に、内容器１の外ケース２への装着および蓋部材３の取り付けについての概説図を示す。まず蓋部材３の内容器１への取り付けについて説明する。同図（ａ）及び同図（ｂ）に示すように、蓋部材３には、内容器１の上端面が入り込む周状溝３３が形成されており、周状溝３３には弾性を有するシール部材Ｓが装着されている。蓋部材３を内容器１に取り付ける場合は、内容器１の上端面に蓋部材３の周状溝３３を填め入れる。そして蓋部材３を内容器１の方向に若干押圧した状態で、蓋部材３の内フラップ５（図３に図示）の係止爪５１（図３に図示）を内容器１の係止部１５に係合させる。具体的構成を図３に示す。   FIG. 2 is a schematic diagram showing how the inner container 1 is attached to the outer case 2 and how the lid member 3 is attached. First, attachment of the lid member 3 to the inner container 1 will be described. As shown in FIGS. 2A and 2B, the lid member 3 is formed with a circumferential groove 33 into which the upper end surface of the inner container 1 enters, and the circumferential groove 33 has an elastic seal. A member S is mounted. When attaching the lid member 3 to the inner container 1, the circumferential groove 33 of the lid member 3 is inserted into the upper end surface of the inner container 1. Then, in a state where the lid member 3 is slightly pressed in the direction of the inner container 1, the latching claw 51 (illustrated in FIG. 3) of the inner flap 5 (illustrated in FIG. 3) of the lid member 3 is engaged with the latching portion 15 of the inner container 1. Engage with. A specific configuration is shown in FIG.

図３に示すように、蓋部材３に回動自在に取り付けられた内フラップ５の一方面に係止爪５１が形成されている。そして内容器１の、内フラップ５に対応する位置に係止部１５が形成されている。内容器１に蓋部材３を取り付け、蓋部材３を若干押圧してシール部材Ｓを圧縮させた状態で内フラップ５を回動させて、内フラップ５の係止爪５１を内容器１の係止部１５に引っかける。これによって、内容器１の上面開口１１を塞ぐように蓋部材３が内容器１に固定される。このとき、シール部材Ｓが蓋部材３と内容器１とによって圧縮されるので、内容器１内に貯溜された飲料液体が蓋部材３と内容器１の間から漏れ出ることが確実に防止される。また同時に、シール部材Ｓの弾性によって蓋部材３は内容器１から離れる方向に力を受けるので、図４に示すように、一度係合した係止爪５１と係止部１５とはしっかりと連結され、同図において時計回り方向の力を内フラップ５に加えない限り、両者の係合状態が解除されることはない。   As shown in FIG. 3, a locking claw 51 is formed on one surface of the inner flap 5 that is rotatably attached to the lid member 3. And the latching | locking part 15 is formed in the position corresponding to the inner flap 5 of the inner container 1. FIG. The lid member 3 is attached to the inner container 1, the inner flap 5 is rotated in a state where the lid member 3 is slightly pressed to compress the seal member S, and the locking claw 51 of the inner flap 5 is engaged with the inner container 1. Hook on the stop 15. Accordingly, the lid member 3 is fixed to the inner container 1 so as to close the upper surface opening 11 of the inner container 1. At this time, since the sealing member S is compressed by the lid member 3 and the inner container 1, the beverage liquid stored in the inner container 1 is reliably prevented from leaking between the lid member 3 and the inner container 1. The At the same time, the cover member 3 receives a force in a direction away from the inner container 1 due to the elasticity of the seal member S, so that the engagement claw 51 and the engagement portion 15 once engaged are firmly connected as shown in FIG. In this figure, the engagement state between the two is not released unless a clockwise force is applied to the inner flap 5.

次に、図２（ｃ）に示すように、蓋部材３が取り付けられた内容器１を外ケース２に収納すると、内容器１の外周に形成された突起１２と、外ケース２の内底面に形成された突起２２とによって、内容器１の外周面と外ケース２の内周面との間に空隙が形成される。また同時に、内容器１の外周面上部に形成された突条１４によって空隙の上部開口は閉鎖される。これにより、内容器１の外周面と外ケース２の内周面との間に密閉された空間が形成され、この密封された空間が断熱効果を奏して、内容器１内に貯溜された飲料液体の温度変化が効果的に抑えられる。   Next, as shown in FIG. 2C, when the inner container 1 to which the lid member 3 is attached is stored in the outer case 2, the protrusion 12 formed on the outer periphery of the inner container 1 and the inner bottom surface of the outer case 2. A gap is formed between the outer peripheral surface of the inner container 1 and the inner peripheral surface of the outer case 2 by the protrusions 22 formed on the inner surface. At the same time, the upper opening of the gap is closed by the protrusion 14 formed on the outer peripheral surface of the inner container 1. As a result, a sealed space is formed between the outer peripheral surface of the inner container 1 and the inner peripheral surface of the outer case 2, and this sealed space has a heat insulating effect and is stored in the inner container 1. The temperature change of the liquid is effectively suppressed.

なお、図６に示すように、突条１４の頂面に周状溝１４１を形成するとともに、周状溝１４１と対向するように外ケース２の内周面に第２突条２４を形成し、外ケース２に内容器１を装着すると、突条１４の周状溝１４１と外ケース２の第２突条２４が係合するようにしてもよい。このような構成とすることによって、突条１４による、内容器１と外ケース２との間の空隙の密閉性が一層向上する。また外ケース２への内容器１の装着完了が音や振動などによって感じることができるようになる。もちろん、突条１４の頂面に第２突条を形成し、外ケース２の内周面に周状溝を形成しても構わない。   As shown in FIG. 6, a circumferential groove 141 is formed on the top surface of the protrusion 14, and a second protrusion 24 is formed on the inner peripheral surface of the outer case 2 so as to face the circumferential groove 141. When the inner container 1 is mounted on the outer case 2, the circumferential groove 141 of the protrusion 14 and the second protrusion 24 of the outer case 2 may be engaged. By setting it as such a structure, the sealing performance of the space | gap between the inner container 1 and the outer case 2 by the protrusion 14 is improved further. Further, the completion of the mounting of the inner container 1 to the outer case 2 can be felt by sound or vibration. Of course, the second protrusion may be formed on the top surface of the protrusion 14, and the circumferential groove may be formed on the inner peripheral surface of the outer case 2.

また内容器１と外ケース２との間の空隙は、冷却剤や加温剤を収納する空間としても利用される。空隙に、冷却剤又は加温剤を収納する空間を形成すれば、冷却剤又は加温剤によって内容器１に貯溜された飲料液体を積極的に冷却又は加温することができるようになる。冷却剤及び加熱剤としては従来公知のものを使用できる。冷却剤又は加温剤を収納する空間は、空隙のどこに形成してもよいが、内容器１の着脱の障害にならない点で、内容器１の外底面と外ケース２の内底面との間が好ましい。   Moreover, the space | gap between the inner container 1 and the outer case 2 is utilized also as a space which accommodates a coolant and a heating agent. If a space for accommodating a coolant or a warming agent is formed in the gap, the beverage liquid stored in the inner container 1 can be actively cooled or warmed by the coolant or the warming agent. A conventionally well-known thing can be used as a cooling agent and a heating agent. The space for storing the coolant or the warming agent may be formed anywhere in the gap, but it does not obstruct the attachment / detachment of the inner container 1, so that it is between the outer bottom surface of the inner container 1 and the inner bottom surface of the outer case 2.

内容器１の外ケース２への固定は、内容器１に装着した蓋部材３を外ケース２に固定することにより行われる。具体的構成を図５及び図６に示す。蓋部材３に回動自在に取り付けられた外フラップ６の一方面に、横方向に離隔して２つの係止爪６１ａ，６１ｂが形成されている。そして外ケース２の、外フラップ６に対応する位置に２つの係止部２３ａ，２３ｂが形成されている。上面開口１１が蓋部材３で密閉された内容器１を外ケース２に収納した後、蓋部材３を若干押圧しながら外フラップ６を回動させて、外フラップ６の係止爪６１ａ，６１ｂを外ケース２の係止部２３ａ，２３ｂにそれぞれ引っかける（図５（ｃ））。このときのＢ−Ｂ線断面図を図６に示す。図６から理解されるように、一度係合した係止爪６１ａと係止部２３ａとはしっかりと連結され、同図において時計回り方向の力を外フラップ６に加えない限り、両者の係合状態が解除されることはない。   The inner container 1 is fixed to the outer case 2 by fixing the lid member 3 attached to the inner container 1 to the outer case 2. A specific configuration is shown in FIGS. Two locking claws 61a and 61b are formed on one surface of the outer flap 6 rotatably attached to the lid member 3 so as to be laterally separated. And two latching | locking parts 23a and 23b are formed in the position corresponding to the outer flap 6 of the outer case 2. As shown in FIG. After the inner container 1 whose upper surface opening 11 is sealed with the lid member 3 is stored in the outer case 2, the outer flap 6 is rotated while slightly pressing the lid member 3, so that the locking claws 61 a and 61 b of the outer flap 6 are rotated. Is hooked on the locking portions 23a and 23b of the outer case 2 (FIG. 5C). A cross-sectional view taken along line BB at this time is shown in FIG. As will be understood from FIG. 6, the engaging claw 61a and the engaging portion 23a once engaged are firmly connected, and unless the force in the clockwise direction is applied to the outer flap 6 in FIG. The state is never released.

このような構成の飲料容器において、飲料液体は内容器１に注ぎ入れられる。蓋部材３を内容器１に取り付けた状態で、飲み口３２から飲料液体を内容器１に注ぎ入れてもよいし、内容器１から蓋部材３を外し、内容器１の上面開口１１から飲料液体を内容器１に注ぎ入れてもよい。   In the beverage container having such a configuration, the beverage liquid is poured into the inner container 1. With the lid member 3 attached to the inner container 1, the beverage liquid may be poured into the inner container 1 from the drinking mouth 32, or the lid member 3 is removed from the inner container 1, and the beverage is discharged from the upper surface opening 11 of the inner container 1. A liquid may be poured into the inner container 1.

本発明の飲料容器の大きな特徴の一つは、内容器１内に飲料液体を入れた状態で、例えば冷蔵庫や冷凍庫に入れて冷却や冷凍することができ、また電子レンジで加温することもできることにある。従来のいわゆる魔法瓶では、冷たい又は温かい飲料液体を携帯したい場合には、飲料液体を別の容器に入れて予め冷却又は加温した後に、魔法瓶に入れる必要があるのに対し、本発明の飲料容器では、内容器１に飲料液体を入れた状態で冷却又は加温することができるので利便性が向上する。もちろん、予め冷却や加温して所望の温度とした飲料液体を内容器１に注ぎ入れても構わない。なお、飲料液体を内容器１に入れた後に凍結や加温する場合は、凍結や加温によって飲料液体の体積が膨張して内容器１が変形するおそれがあるので、内容器１の変形を抑えるため、図１に示したように内容器１にリブ１３ａ，１３ｂを形成したり、あるいは弾性を有する材料を用いたりするのが好ましい。   One of the major features of the beverage container of the present invention is that the beverage liquid is put in the inner container 1 and can be cooled or frozen in a refrigerator or a freezer, for example, or heated in a microwave oven. There is something you can do. In a conventional so-called thermos bottle, when it is desired to carry a cold or warm beverage liquid, it is necessary to put the beverage liquid in a separate container and then cool or warm it in advance, and then put it in the thermos bottle, whereas the beverage container of the present invention Then, since it can cool or heat in the state which put the drink liquid in the inner container 1, the convenience improves. Of course, you may pour into the inner container 1 the drink liquid which cooled and heated previously and was made into the desired temperature. In addition, when freezing or heating after putting a drink liquid in the inner container 1, since the volume of a drink liquid expand | swells by freezing or heating, there exists a possibility that the inner container 1 may deform | transform. In order to suppress it, it is preferable to form ribs 13a and 13b in the inner container 1 as shown in FIG. 1 or to use an elastic material.

そして飲料液体が入れられた内容器１を外ケース２に装着し、蓋部材３の外フラップ６によって内容器１を外ケース２に取り付ける。これによって、飲料容器の保温性が向上し飲料液体の温度変化が抑えられる。   Then, the inner container 1 containing the beverage liquid is attached to the outer case 2, and the inner container 1 is attached to the outer case 2 by the outer flap 6 of the lid member 3. Thereby, the heat retaining property of the beverage container is improved and the temperature change of the beverage liquid is suppressed.

また内容器１内を掃除する場合、内容器１から蓋部材３を取り外せば、大きく開いた内容器１の上面開口１１から内容器内を容易に掃除できるようになる。   Further, when cleaning the inside of the inner container 1, if the lid member 3 is removed from the inner container 1, the inside of the inner container 1 can be easily cleaned from the upper surface opening 11 of the inner container 1 that is wide open.

本発明の飲料容器の形状に特に限定はないが、前記実施形態で示したような薄い直方体形状とすると、鞄などに入れた際に円筒形状をした従来の容器に比べて嵩張らず収納性が向上する。   The shape of the beverage container of the present invention is not particularly limited, but if it is a thin rectangular parallelepiped shape as shown in the above embodiment, it is not bulky and can be stored as compared to a conventional container having a cylindrical shape when placed in a basket or the like. improves.
