Description

本発明は、飲食物収容容器における有底筒状の容器本体の開口を覆う飲食物収容容器用蓋及びその蓋を用いた飲食物収容容器に関する。 The present invention relates to a food and drink storage container lid that covers the opening of the bottomed tubular container body in the food and drink storage container, and a food and drink storage container using the lid.

近時、持ち帰り形態（テイクアウト形態）の飲食物商品には、飲食物収容容器における有底円筒状の容器本体内に飲食物を収容した上でその容器本体の開口を蓋により施蓋するものがある。この飲食物収容容器に用いられる蓋は、一般に、特許文献１に示すように、その飲食物収容容器における容器本体の開口を覆う天面板部と、その天面板部の外周縁から天面板部の裏面側に伸びて、天面板部が容器本体の開口を覆ったときにその容器本体の開口周縁部に係合可能となる側周壁部と、を一体的に備えている。 Recently, some food and beverage products in the take-out form (take-out form) contain food and drink in a bottomed cylindrical container body of the food and drink storage container, and then cover the opening of the container body with a lid. be. As shown in Patent Document 1, the lid used for this food and drink container is generally a top plate portion that covers the opening of the container body in the food and drink storage container, and a top plate portion from the outer peripheral edge of the top plate portion. It integrally includes a side peripheral wall portion that extends to the back surface side and becomes engageable with the opening peripheral edge portion of the container body when the top plate portion covers the opening of the container body.

ところで、複数の飲食物収容容器を同時に運びたい場合がある。例えば、テイクアウトショップにおいて、複数の飲食物商品を飲食物収容容器にそれぞれ収容された状態で購入し、その複数の飲食物収容容器を持ち帰るような場合である。このような場合、飲食物収容容器が片手で把持できるものであれば、一人の購入者は、両手を使用することにより、２つの飲食物収容容器を持ち帰ることができる。 By the way, there are cases where it is desired to carry a plurality of food and drink storage containers at the same time. For example, in a take-out shop, a plurality of food and drink products are purchased in a state of being housed in each of the food and drink storage containers, and the plurality of food and drink storage containers are brought back. In such a case, if the food and drink storage container can be grasped with one hand, one purchaser can bring back the two food and drink storage containers by using both hands.

しかし、飲食物収容容器の外径が購入者の手にとって大きい場合には（例えばラージサイズ）、その購入者が各片手でその飲食物収容容器をそれぞれ持つことは容易ではない。また、一人の購入者が飲食物収容容器を同時に３つ以上持ち帰りたい場合があり、そのような場合には、最早、その数の全部を手で持って帰ることはできない。 However, when the outer diameter of the food / drink container is large for the purchaser's hand (for example, large size), it is not easy for the purchaser to hold the food / drink storage container with each hand. In addition, one purchaser may want to bring back three or more food and drink storage containers at the same time, and in such a case, it is no longer possible to bring back all of them by hand.

このような場合、厚紙を用いて形成された搬送用具を用いることが考えられる。この搬送用具は、厚紙を折り込むことによりベースを形成し、そのベース上面に飲食物収容容器の下部を嵌め込むための凹所を複数形成することとなっており、複数の飲食物収容容器を同時に持ち運ぶに当たり、その各凹所に飲食物収容容器の下部をそれぞれ嵌め込んだ上で、そのベースを手で持って運ぶこととなる。しかし、上記搬送用具を用いて多くの数の飲食物収容容器を持ち運ぼうとした場合、それに応じた多数の凹所を形成するためのベース上面の面積を大きくすると共に、そのベースの強度を高めなければならない。その一方で、上記搬送用具は、一人の購入者が持ち運べるベース上面の平面的な大きさには自ずと限界があり、これに伴い、そのベース上面に形成される凹所の数は制約されることになる。 In such a case, it is conceivable to use a transport tool formed of thick paper. In this transport tool, a base is formed by folding thick paper, and a plurality of recesses for fitting the lower portion of the food and drink storage container are formed on the upper surface of the base, and a plurality of food and drink storage containers can be simultaneously formed. When carrying it, the lower part of the food and drink storage container is fitted into each recess, and then the base is carried by hand. However, when trying to carry a large number of food and drink storage containers using the above-mentioned transport tool, the area of the upper surface of the base for forming a corresponding number of recesses must be increased and the strength of the base must be increased. Must be. On the other hand, in the above-mentioned transport tool, the flat size of the upper surface of the base that can be carried by one purchaser is naturally limited, and accordingly, the number of recesses formed on the upper surface of the base is limited. become.

本発明は、上記実情に鑑みてなされたもので、その目的は、持ち運ぶことができる飲食物収容容器の数を効率的に高めることができる飲食物収容容器用蓋及びその蓋を用いた飲食物収容容器を提供することにある。 The present invention has been made in view of the above circumstances, and an object thereof is a lid for a food and drink storage container capable of efficiently increasing the number of food and drink storage containers that can be carried, and a food and drink using the lid. To provide a containment container.

前記目的を達成するために本発明にあっては、下記（１）〜（９）とした構成とされている。 In order to achieve the above object, the present invention has the following configurations (1) to (9).

（１）容器本体の開口を覆う天面板部と、該天面板部の外周側から該天面板部の裏面側に連続的に伸びて前記容器本体の開口を前記天面板部が覆うようにされたとき該容器本体の開口周縁部に係合可能となる側周壁部と、を備える飲食物収容容器用蓋において、
前記天面板部の表面に、少なくとも、前記容器本体の下部が嵌合できる凹所が形成されている構成とされている。 (1) The top plate portion that covers the opening of the container body and the top plate portion that continuously extends from the outer peripheral side of the top plate portion to the back surface side of the top plate portion so that the top plate portion covers the opening of the container body. In a food / drink storage container lid provided with a side peripheral wall portion that can be engaged with the opening peripheral edge portion of the container body.
The surface of the top plate portion is configured to have at least a recess in which the lower portion of the container body can be fitted.

上記構成によれば、当該蓋をもって容器本体の開口を施蓋すれば、その蓋における凹所に別の飲食物収容容器の下部を嵌合できることになり、飲食物収容容器を順次、倒すことなく安定した状態で積み上げることができ、飲食物収容容器を積み上げた状態で支障なく持ち運ぶことができる。このため、当該蓋における天面板部に凹所を形成するだけの簡単な構成により、飲食物収容容器を手で直接もって運ぶ場合、搬送用具を用いる場合のいずれの場合でも、持ち運ぶことができる飲食物収容容器の数を増大させることができ、持ち運ぶことができる飲食物収容容器の数を効率的に高めることができる。また、当該蓋を容器本体から外して飲料を飲むに際しては、当該蓋の側周壁部が区画する領域の径（側周壁部先端（下端）における径）が凹所の径（容器本体の底面外径）よりも大きいことから、当該蓋の凹所に容器本体の下部を嵌合してその蓋（側周縁部先端（下端））を介して容器本体をテーブル上面等の載置面に載置したときには、テーブル上面等の載置面に容器本体自体を載置する場合よりも、安定性を高めることができる。このため、特に、振動を生じる乗り物等において、当該蓋を、容器本体の転倒防止を高める容器受け又はコースタとして用いることができる。 According to the above configuration, if the opening of the container body is closed with the lid, the lower part of another food and drink storage container can be fitted into the recess in the lid, and the food and drink storage container is not sequentially tilted. It can be stacked in a stable state, and the food and drink storage containers can be carried in a stacked state without any trouble. For this reason, with a simple structure that only forms a recess in the top plate of the lid, the food and drink can be carried regardless of whether the food or drink storage container is carried directly by hand or when a transport tool is used. The number of food storage containers can be increased, and the number of food and drink storage containers that can be carried can be efficiently increased. When the lid is removed from the container body to drink a beverage, the diameter of the region defined by the side peripheral wall portion of the lid (the diameter at the tip (lower end) of the side peripheral wall portion) is the diameter of the recess (outside the bottom surface of the container body). Since it is larger than the diameter), the lower part of the container body is fitted into the recess of the lid, and the container body is placed on a mounting surface such as the upper surface of a table via the lid (tip (lower end) of the side peripheral edge). When this is done, the stability can be improved as compared with the case where the container body itself is placed on a mounting surface such as the upper surface of a table. Therefore, the lid can be used as a container receiver or a coaster to improve the prevention of the container body from tipping over, especially in a vehicle or the like that generates vibration.

（２）前記（１）の構成の下で、
前記凹所の内周壁が、該凹所の開口から該開口に近い側において、前記容器本体の下部を緩嵌合するための緩嵌合部として形成されている一方、該凹所の内周壁には、該緩嵌合部よりも凹所の底部側において、該容器本体の下部を密嵌合するための密嵌合部が形成されている構成とされている。 (2) Under the configuration of (1) above,
The inner peripheral wall of the recess is formed as a loose fitting portion for loosely fitting the lower portion of the container body on the side close to the opening from the opening of the recess, while the inner peripheral wall of the recess is formed. Is configured to form a tight fitting portion for tightly fitting the lower portion of the container body on the bottom side of the recess from the loose fitting portion.

この構成によれば、当該蓋が用いられる容器本体とは異なる別の容器本体の下部を当該蓋の凹所に嵌合するに当たり、その容器本体の下部を、緩嵌合部に容易に進入させた上で、密嵌合部に押し込むことができ、凹所に対して容器本体の下部を容易に密嵌合状態で嵌合することができる。 According to this configuration, when the lower part of the container body different from the container body in which the lid is used is fitted into the recess of the lid, the lower part of the container body is easily allowed to enter the loose fitting portion. Then, it can be pushed into the tightly fitted portion, and the lower part of the container body can be easily fitted in the tightly fitted state with respect to the recess.

（３）前記（１）の構成の下で、
前記凹所の内周壁は、該凹所の底部から開口に向けて段階的に拡径されて、内径が異なった複数の内周壁部をもって形成され、
前記複数の内周壁部のうちの一つが、前記容器本体の下部を嵌合するための内周壁部とされ、
前記複数の内周壁部のうちの他のものが、前記容器本体の下部外径とは異なる下部外径を有する容器本体の下部を嵌合するための内周壁部とされている構成とされている。 (3) Under the configuration of (1) above,
The inner peripheral wall of the recess is formed by having a plurality of inner peripheral walls having different inner diameters by gradually expanding the diameter from the bottom of the recess toward the opening.
One of the plurality of inner peripheral wall portions is used as an inner peripheral wall portion for fitting the lower portion of the container body.
Other of the plurality of inner peripheral wall portions is configured to be an inner peripheral wall portion for fitting the lower portion of the container body having a lower outer diameter different from the lower outer diameter of the container body. There is.

上記構成によれば、下部外径が同じである容器本体の下部だけでなく、下部外径が異なる容器本体の下部を当該蓋の該当内周壁部に嵌合できることになり、当該蓋を用いれば、飲食物収容容器上に、同一の下部外径の飲食物収容容器だけでなく、異なった下部外径の飲食物収容容器を積み上げ保持でき、便宜性を高めることができる。 According to the above configuration, not only the lower part of the container body having the same lower outer diameter but also the lower part of the container body having a different lower outer diameter can be fitted to the corresponding inner peripheral wall portion of the lid. , Not only food and drink storage containers having the same lower outer diameter but also food and drink storage containers having different lower outer diameters can be stacked and held on the food and drink storage container, and convenience can be enhanced.

（４）前記（３）の構成の下で、
前記複数の内周壁部のうちの一つが、前記凹所の底部から立ち上がる下段側内周壁部とされ、
前記複数の内周壁部のうちの他のものが、前記下段側内周壁部の上側において、段差部を経て拡径された状態の下で前記凹所の開口にまで立ち上がる上段側内周縁部とされている構成とされている。 (4) Under the configuration of (3) above,
One of the plurality of inner peripheral wall portions is a lower inner peripheral wall portion that rises from the bottom of the recess.
Other of the plurality of inner peripheral wall portions has an upper inner peripheral edge portion that rises to the opening of the recess on the upper side of the lower stage side inner peripheral wall portion in a state where the diameter is expanded through the step portion. It is said that it is configured.

この構成によれば、当該蓋が用いられる容器本体と同じ下部外径を有する容器本体の下部を下段側内周壁部に嵌合でき、その容器本体の下部外径よりも大きい下部外径を有する容器本体の下部を上段側内周壁部に嵌合できることになり、当該蓋上に、下部外径が異なる２種類の容器本体のいずれかを安定的に積み上げることができる。 According to this configuration, the lower part of the container body having the same lower outer diameter as the container body in which the lid is used can be fitted to the lower inner peripheral wall portion, and has a lower outer diameter larger than the lower outer diameter of the container body. The lower part of the container body can be fitted to the inner peripheral wall portion on the upper stage side, and one of two types of container bodies having different lower outer diameters can be stably stacked on the lid.

（５）前記（１）〜（４）のいずれかの構成の下で、
前記凹所の内周壁に、該凹所の開口から底部内面に至る溝が形成されている構成とされている。 (5) Under any of the configurations (1) to (4) above,
The inner peripheral wall of the recess is configured to have a groove from the opening of the recess to the inner surface of the bottom.

この構成によれば、溝は、当該蓋のブレ止めと回転防止、さらには、当該蓋の積み重ね時のブロッキングを防止するだけでなく、飲食物収容容器内に冷たい飲食物を収容した状態の下で、当該蓋を容器受け又はコースタとして使用すべく、その容器本体の下部を当該蓋の凹所に嵌合したときには、その容器本体の外側側面に結露が生じても、その結露水をその容器本体の外側側面を伝って落下させ、その結露水を、溝を利用してさらに凹所内に落とし込むことができる。このため、容器本体における外側側面から結露水を排除できると共に、その結露水を視認できない状態（凹所内に収容状態）として、飲食物収容容器の使用時の見栄えを向上させることができる。 According to this configuration, the groove not only prevents the lid from shaking and rotating, and also prevents blocking when the lids are stacked, but also under the condition that cold food and drink are stored in the food and drink storage container. Then, when the lower part of the container body is fitted into the recess of the lid so that the lid can be used as a container holder or coaster, even if dew condensation occurs on the outer side surface of the container body, the dew water is used in the container. It can be dropped along the outer side surface of the main body, and the dew condensation water can be further dropped into the recess by using the groove. Therefore, the dew condensation water can be removed from the outer side surface of the container body, and the appearance of the food / drink storage container can be improved by making the dew condensation water invisible (contained in the recess).

（６）前記（１）〜（５）のいずれかの構成の下で、
前記側周縁部の先端が、載置面に対する載置端として、前記凹所の底部よりも該凹所底部の裏面側外方に位置されている構成とされている。 (6) Under any of the configurations (1) to (5) above,
The tip of the side peripheral edge portion is configured to be located on the outer side of the back surface side of the bottom portion of the recess as the mounting end with respect to the mounting surface.

この構成によれば、当該蓋の凹所に容器本体の下部を嵌合して当該蓋を容器受け又はコースタとして用いるときには、側周縁部のきわめて細い先端（下端）だけが伝導面積として載置面に当接し、載置面と当該蓋の裏面との間には断熱層としての空気層が存在することになる。これにより、容器本体内に収容される飲食物の温度が変化することを極力抑制することができる。 According to this configuration, when the lower part of the container body is fitted into the recess of the lid and the lid is used as a container receiver or coaster, only the extremely thin tip (lower end) of the side peripheral edge is the mounting surface as the conduction area. An air layer as a heat insulating layer is present between the mounting surface and the back surface of the lid. As a result, it is possible to suppress changes in the temperature of food and drink contained in the container body as much as possible.

（７）前記（１）〜（６）のいずれかの構成の下で、
飲み口が、前記凹所の径方向外方位置に設けられて、飲料容器用蓋とされている構成とされている。 (7) Under any of the configurations (1) to (6) above,
The drinking spout is provided at the radial outer position of the recess to serve as a lid for a beverage container.

この構成によれば、飲み口を有する飲料容器用蓋であっても、前述の（１）と同様の作用効果を得ることができる。 According to this configuration, even a beverage container lid having a drinking spout can obtain the same action and effect as the above-mentioned (1).

（８）前記（７）の構成の下で、
前記飲み口が、前記天面板部表面から上方に突設され、
前記飲み口の先端面に、前記天面板部の表面側と裏面側とを連通する飲料流出入孔が形成され、
前記飲み口には、該飲み口における先端面の外側縁から前記側周縁部の先端側に向けて垂下する縦壁部が形成され、
前記縦壁部のうち、前記飲み口における先端面の外側縁に連続する部分が、該飲み口における先端面の外側縁よりも内方側に引っ込むように傾斜されている構成とされている。 (8) Under the configuration of (7) above,
The spout is projected upward from the surface of the top plate portion, and the spout is projected upward.
A beverage inflow / outflow hole that communicates the front surface side and the back surface side of the top plate portion is formed on the tip surface of the drinking spout.
A vertical wall portion is formed in the spout so as to hang down from the outer edge of the tip surface of the spout toward the tip side of the side peripheral edge portion.
The portion of the vertical wall portion continuous with the outer edge of the tip surface of the spout is inclined so as to be retracted inward from the outer edge of the tip surface of the spout.

この構成によれば、飲み口先端面と、縦壁部のうち、飲み口先端面の外側縁から連続する部分とが、尖った形状を形成しており、その尖った形状の先端（飲み口先端面の外側縁又は縦壁部の上端）に至った飲料は、微視的には、表面張力に基づき、その粒形化（接触角の増大化）、その増径化が促進される傾向となり、その粒形化した飲料の重量は、飲み口先端面の外側縁部分での表面張力に基づく引っ張り力に早期に打ち勝つことになる。このため、飲料を飲む者が飲み口から口を外したときには、同時に、飲み口先端面の外側縁において、飲料の液切れが的確に行われ、飲料の液滴が縦壁部を伝うような事態の発生を防止できる。また、縦壁部は、飲み口先端面の外側縁に連続する部分と、それに続く部分と、その両者が形成するへこみ部分とを形成することになり、飲料を飲む者の下唇を縦壁部に沿わせつつ、上記各部分により、その下唇の移動を抑制できる。これにより、飲み口に対する飲料を飲む者の口の安定化を図ることができ、飲み易さを高めることができる。 According to this configuration, the tip surface of the drinking spout and the portion of the vertical wall portion continuous from the outer edge of the tip surface of the drinking spout form a sharp shape, and the pointed tip (drinking spout) is formed. Beverages that reach the outer edge of the tip surface or the upper end of the vertical wall portion tend to be microscopically promoted to be granulated (increased contact angle) and increased in diameter based on the surface tension. The weight of the granulated beverage will quickly overcome the pulling force based on the surface tension at the outer edge of the spout tip surface. For this reason, when the person who drinks the beverage removes the mouth from the mouth, at the same time, the liquid of the beverage is accurately drained at the outer edge of the tip surface of the mouth, and the droplets of the beverage are transmitted along the vertical wall portion. It is possible to prevent the occurrence of a situation. In addition, the vertical wall portion forms a portion continuous with the outer edge of the tip surface of the drinking spout, a portion following the vertical wall portion, and a dented portion formed by both of them, and the lower lip of the drinker is formed on the vertical wall. The movement of the lower lip can be suppressed by each of the above parts while following the part. As a result, it is possible to stabilize the mouth of the person who drinks the beverage with respect to the mouth, and it is possible to improve the ease of drinking.

（９）有底筒状の容器本体と、該容器本体の開口を施蓋する蓋と、を備え、該蓋が、前記容器本体の開口を覆う天面板部と、該天面板部の外周側から該天面板部の裏面側に連続的に延びて前記容器本体の開口を前記天面板部が覆うようにされたとき該容器本体の開口周縁部に係合可能となる側周壁部と、を備えている飲食物収容容器において、
前記蓋における天面板部の表面に、少なくとも、前記容器本体の下部が嵌合できる凹所が形成されている構成されている。 (9) A container body having a bottomed cylinder and a lid for covering the opening of the container body are provided, and the lid covers the opening of the container body and the outer peripheral side of the top plate portion. A side peripheral wall portion that extends continuously from the top plate portion to the back surface side and becomes engageable with the opening peripheral edge portion of the container body when the top plate portion covers the opening of the container body. In the food and drink storage container provided
At least, a recess into which the lower portion of the container body can be fitted is formed on the surface of the top plate portion of the lid.

この構成によれば、前述の（１）の蓋を用いることから、持ち運ぶことができる数を効率的に高めることができる飲食物収容容器を提供できる。 According to this configuration, since the lid of (1) described above is used, it is possible to provide a food and drink storage container that can efficiently increase the number of containers that can be carried.

本発明によれば、持ち運ぶことができる飲食物収容容器の数を効率的に高めることができる飲食物収容容器用蓋及びその蓋を用いた飲食物収容容器を提供できる。 According to the present invention, it is possible to provide a food / drink storage container lid capable of efficiently increasing the number of food / drink storage containers that can be carried, and a food / drink storage container using the lid.

以下、本発明の実施形態を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１において、符号１は、第１実施形態に係る飲食物収容容器としての飲料容器である。この飲料容器１は、有底円筒状の容器本体としての飲料カップ２と、その飲料カップ２の開口２Ａを塞ぐ蓋３と、を備えている。 In FIG. 1, reference numeral 1 is a beverage container as a food and drink storage container according to the first embodiment. The beverage container 1 includes a beverage cup 2 as a bottomed cylindrical container body, and a lid 3 for closing the opening 2A of the beverage cup 2.

前記飲料カップ２は、飲料Ｄを収容するものである。この飲料カップ２における開口２Ａは、平面視円形状の開口周縁部２Ａａにより区画されており、その開口周縁部２Ａａは、その径方向外方に全周に亘って若干、張り出されている。この飲料カップ２の外形は、本実施形態においては、その外径がその開口２Ａから底部２Ｂ側に向けて徐々に縮径されたものとなっており、この飲料カップ２の下部２Ｃは、上記全体的な縮径傾向の下で、蓋３における後述の凹所６に対する嵌合部として局部的に縮径されている。この場合、飲料カップ２の下部２Ｃ外径は、その下部２Ｃとそれよりも上側部分（飲料カップ２）の境界近くを径方向内方に膨出させることにより縮径されており、飲料カップ２における下部２Ｃの外側側面は、その膨出部先端よりも上方側においては、上方に向うに従って拡径するように傾斜され、膨出部先端よりも下方側においては、下方に向かうに従って拡径するように傾斜されることが好ましい（図３、図４参照）。 The beverage cup 2 accommodates the beverage D. The opening 2A in the beverage cup 2 is partitioned by an opening peripheral edge portion 2Aa having a circular shape in a plan view, and the opening peripheral edge portion 2Aa is slightly overhanging outward in the radial direction over the entire circumference. In the present embodiment, the outer diameter of the beverage cup 2 is gradually reduced in diameter from the opening 2A toward the bottom 2B side, and the lower portion 2C of the beverage cup 2 is described above. Under the overall diameter reduction tendency, the diameter is locally reduced as a fitting portion for the recess 6 described later in the lid 3. In this case, the outer diameter of the lower portion 2C of the beverage cup 2 is reduced by bulging inward in the radial direction near the boundary between the lower portion 2C and the portion above the lower portion (beverage cup 2). The outer side surface of the lower portion 2C in the above portion is inclined so as to increase in diameter toward the upper side above the tip of the bulge, and expands in diameter toward the lower side below the tip of the bulge. It is preferable to incline in this way (see FIGS. 3 and 4).

前記蓋３は、図１〜図４に示すように、天面板部４と、側周壁部５と、を一体的に備えている。天面板部４は、蓋３の径方向内方側に配置されて蓋３の主要部分を占めるものであり、蓋３が飲料カップ２の開口２Ａを塞いだときには、その天面板部４は、飲料カップ２の開口２Ａ上に配置されてその開口２Ａの大部分を覆うことになる。 As shown in FIGS. 1 to 4, the lid 3 integrally includes a top plate portion 4 and a side peripheral wall portion 5. The top plate portion 4 is arranged on the radial inward side of the lid 3 and occupies the main part of the lid 3. When the lid 3 closes the opening 2A of the beverage cup 2, the top plate portion 4 is formed. It will be placed on the opening 2A of the beverage cup 2 and will cover most of the opening 2A.

側周壁部５は、前記天面板部４の外周側に全周に亘って連なった状態で形成されている。この側周壁部５は、本実施形態においては、天面板部４の外周部から拡径しつつ天面板部４の裏面側外方へと伸びており、その先端部（下端部）５ａは、径方向外方への拡張部５ｂを経て垂下している。これにより、側周壁部５は、飲料カップ２の開口２Ａを天面板部４が覆ったときには、側周壁部５の拡張部５ｂが飲料カップ２の開口周縁部（張り出し部）２Ａａに載ると共に、その側周壁部５の先端部５ａ内面が飲料カップ２の開口周縁部（張り出し部）２Ａａに係合保持されることになる。本実施形態においては、天面板部４と側周壁部５との連続部分（天面板部４の外周縁部分）が外に膨らむような滑らかな湾曲面をもって湾曲されており、蓋３のうち、その連続部分から拡張部５ｂ（先端部５ａ近く）に至るまでの間も飲料カップ２の開口２Ａを覆うことになる。このような蓋３（天面板部４及び側周壁部５）は、樹脂を用いて一体成形されている。 The side peripheral wall portion 5 is formed in a state of being continuous with the outer peripheral side of the top plate portion 4 over the entire circumference. In the present embodiment, the side peripheral wall portion 5 extends from the outer peripheral portion of the top plate portion 4 to the outside of the back surface side of the top plate portion 4, and the tip portion (lower end portion) 5a thereof is formed. It hangs down through the extension portion 5b in the radial direction. As a result, when the top plate portion 4 covers the opening 2A of the beverage cup 2, the expansion portion 5b of the side peripheral wall portion 5 is placed on the opening peripheral edge portion (overhanging portion) 2Aa of the beverage cup 2. The inner surface of the tip portion 5a of the side peripheral wall portion 5 is engaged and held by the opening peripheral edge portion (overhanging portion) 2Aa of the beverage cup 2. In the present embodiment, the continuous portion between the top plate portion 4 and the side peripheral wall portion 5 (the outer peripheral edge portion of the top plate portion 4) is curved with a smooth curved surface that bulges outward, and the lid 3 has a smooth curved surface. The opening 2A of the beverage cup 2 is also covered from the continuous portion to the expansion portion 5b (near the tip portion 5a). Such a lid 3 (top plate portion 4 and side peripheral wall portion 5) is integrally molded using a resin.

前記蓋３における天面板部４の表面には、図１〜図４に示すように、その径方向内方側部分を該天面板部４の裏面側外方に向けて膨出させることにより、平面視円形状の凹所６が形成されている。この凹所６は、その内周壁７が飲料カップ２の下部２Ｃを嵌合できる大きさ（内径）に形成され、この凹所６の内周壁７には、凹所６の開口６Ａから底部６Ｂに向けて順に、飲料カップ２の下部２Ｃを緩嵌合できる緩嵌合部８と、該飲料カップ２の下部２Ｃを密嵌合できる密嵌合部９とが形成されている。緩嵌合部８は、内径が飲料カップ２の下部２Ｃ外径よりも若干、大きくされた内周壁部として形成されている。密嵌合部９は、本実施形態においては、緩嵌合部８の下端に続く部分を凹所６全周に亘って径方向内方に若干、膨出させることにより、環状突部（符号９を用いる）として形成されており、その環状突部９先端が形成する内径は、飲料カップ２の下部２Ｃ外径よりも若干、小さくされている。この場合、図３、図４に示すように、環状突部９の上面（凹所６開口６Ａ側の面）については、飲料カップ２を密嵌合部９に的確に案内すべく、下方に向かうほど径方向内方に向かうように傾斜され、環状突部９の下面については、下方に向かうほど径方向外方に拡がるように傾斜されることが好ましい。 As shown in FIGS. 1 to 4, on the surface of the top plate portion 4 of the lid 3, the radial inner side portion thereof is bulged toward the back surface side outer side of the top plate portion 4. The concave portion 6 having a circular shape in a plan view is formed. The inner peripheral wall 7 of the recess 6 is formed to have a size (inner diameter) that allows the lower portion 2C of the beverage cup 2 to be fitted, and the inner peripheral wall 7 of the recess 6 has an opening 6A to a bottom 6B of the recess 6. In order, a loose fitting portion 8 capable of loosely fitting the lower portion 2C of the beverage cup 2 and a tight fitting portion 9 capable of tightly fitting the lower portion 2C of the beverage cup 2 are formed. The loose fitting portion 8 is formed as an inner peripheral wall portion whose inner diameter is slightly larger than the outer diameter of the lower portion 2C of the beverage cup 2. In the present embodiment, the tightly fitted portion 9 has an annular protrusion (reference numeral) by slightly inflating the portion following the lower end of the loosely fitted portion 8 inward in the radial direction over the entire circumference of the recess 6. 9 is used), and the inner diameter formed by the tip of the annular protrusion 9 is slightly smaller than the outer diameter of the lower 2C of the beverage cup 2. In this case, as shown in FIGS. 3 and 4, the upper surface of the annular protrusion 9 (the surface on the recess 6 opening 6A side) is lowered so as to accurately guide the beverage cup 2 to the tightly fitted portion 9. It is preferable that the lower surface of the annular protrusion 9 is inclined so as to expand inward in the radial direction toward the downward direction, and the lower surface of the annular protrusion 9 is inclined so as to expand outward in the radial direction toward the downward direction.

前記凹所６の内周壁７には、図１、図２に示すように、複数（本実施形態においては４つ）の溝１１が形成されている。この複数の溝１１は、凹所６の周回り方向に等間隔ごとに配置されており、その各溝１１は、凹所６の開口６Ａから凹所６の底部６Ｂ内面に至るように伸びている。この各溝１１は、当該蓋３のブレ止めと回転防止、さらには、当該蓋３の積み重ね時のブロッキング防止を図るだけでなく、飲料カップ２の下部２Ｃが凹所６内に嵌合されたときに、凹所６の内周壁７と飲料カップ２の外側側面との間において排水路１２を構成することになる。排水路１２については、後述する。 As shown in FIGS. 1 and 2, a plurality of (four in this embodiment) grooves 11 are formed on the inner peripheral wall 7 of the recess 6. The plurality of grooves 11 are arranged at equal intervals in the circumferential direction of the recess 6, and each groove 11 extends from the opening 6A of the recess 6 to the inner surface of the bottom 6B of the recess 6. There is. Each of the grooves 11 not only prevents the lid 3 from shaking and rotating, and also prevents the lid 3 from blocking when the lids 3 are stacked, and the lower portion 2C of the beverage cup 2 is fitted in the recess 6. Occasionally, a drainage channel 12 is formed between the inner peripheral wall 7 of the recess 6 and the outer side surface of the beverage cup 2. The drainage channel 12 will be described later.

前記蓋３には、図１〜図３に示すように、前記凹所６の径方向外方位置において飲み口１４が形成されている。この飲み口１４は、天面板部４から側周壁部５にかけての領域において、天面板部４表面からその上方に多少、膨出するように形成され、その先端面１４ａは、飲料を飲む者の口に含めることができる程度の大きさをもって、天面板部４の径方向の長さよりも周方向（図２中、上下方向）の長さが長くなるように細幅形状に形成されている。 As shown in FIGS. 1 to 3, the lid 3 is formed with a drinking spout 14 at a radial outer position of the recess 6. The drinking spout 14 is formed so as to slightly bulge upward from the surface of the top plate portion 4 in the region from the top plate portion 4 to the side peripheral wall portion 5, and the tip surface 14a thereof is for a person who drinks a beverage. It is formed in a narrow shape so as to have a size that can be included in the mouth and that the length in the circumferential direction (vertical direction in FIG. 2) is longer than the length in the radial direction of the top plate portion 4.

この飲み口１４の先端面１４ａには、図１、図２に示すように、飲料流出入孔としての２つのストロー用穴１５ａ、１５ｂが形成されている。この２つの穴１５ａ、１５ｂは、天面板部４の周方向に並設された状態で形成され、その２つの穴１５ａと穴１５ｂとは、本実施形態においては、同方向に直接的に連なっている。各穴１５ａ、１５ｂは、一般的な所定径（例えば６ｍｍ）のストローを差し込むことができることになっており、その各穴１５ａ、１５ｂに相当径のストローが差し込まれたときには、そのストローは、各穴１５ａ、１５ｂの周縁部との係合により、起立された状態が保持される。これにより、２つの穴１５ａ、１５ｂのいずれか一方の穴にストローを差し込むことにより、そのストローにより飲料カップ２２内の飲料を吸引しながら飲料を飲むことができ、そのとき、他方の穴を、ストローによる飲料吸引時の空気取り入れ孔として用いることができる。 As shown in FIGS. 1 and 2, two straw holes 15a and 15b are formed on the tip surface 14a of the drinking spout 14 as beverage inflow / outflow holes. The two holes 15a and 15b are formed in a state of being arranged side by side in the circumferential direction of the top plate portion 4, and the two holes 15a and the holes 15b are directly connected in the same direction in the present embodiment. ing. A straw having a general predetermined diameter (for example, 6 mm) can be inserted into each of the holes 15a and 15b, and when a straw having a corresponding diameter is inserted into each of the holes 15a and 15b, the straw is inserted into each of the holes 15a and 15b. The standing state is maintained by engaging with the peripheral portions of the holes 15a and 15b. Thereby, by inserting a straw into one of the two holes 15a and 15b, the beverage can be drunk while sucking the beverage in the beverage cup 22 by the straw, and at that time, the other hole can be inserted into the other hole. It can be used as an air intake hole when sucking a beverage with a straw.

また、飲み口１４においては、２つの穴１５ａ、１５ｂが直接的に連なって拡大された穴を形成していることから、その２つの穴１５ａ、１５ｂを利用することにより、飲料を飲む者は、飲み口１４を口に含んでその飲み口１４から直接、飲料カップ２２内の飲料を飲むこともできる。勿論、蓋３を飲料カップ２から外して、その飲料カップ２の開口周縁部２Ａａに口をつけ又はストローを用いて飲料カップ２内の飲料を飲むこともできる。 Further, in the drinking spout 14, the two holes 15a and 15b are directly connected to form an enlarged hole. Therefore, by using the two holes 15a and 15b, a person who drinks a beverage can drink. It is also possible to drink the beverage in the beverage cup 22 directly from the mouth 14 by including the mouth 14. Of course, it is also possible to remove the lid 3 from the beverage cup 2 and attach a mouth to the opening peripheral edge 2Aa of the beverage cup 2 or use a straw to drink the beverage in the beverage cup 2.

本実施形態においては、図１、図２、図６に示すように、前記２つの穴１５ａ、１５ｂは、飲み口先端面１４ａに浅いへこみ部１６を形成した上で、そのへこみ部１６に形成されている。このへこみ部１６は、飲み口１４の先端面１４ａの周囲から２つの穴１５ａ、１５ｂに向かうに従って蓋３の裏面側（下側）に向うように傾斜されており、飲料カップ２内の飲料を飲まないときには、仮に、飲み口先端面１４ａに飲料が存在しても、その飲料は、飲み口先端面１４ａにはとどまらずに２つの穴１５ａ、１５ｂを介して飲料カップ２内に導かれる。 In the present embodiment, as shown in FIGS. 1, 2, and 6, the two holes 15a and 15b are formed in the dented portion 16 after forming a shallow dented portion 16 in the spout tip surface 14a. Has been done. The dent portion 16 is inclined so as to face the back surface side (lower side) of the lid 3 from the periphery of the tip surface 14a of the drinking spout 14 toward the two holes 15a and 15b, and the beverage in the beverage cup 2 is served. When not drinking, even if a beverage is present on the tip surface 14a of the mouthpiece, the beverage is guided into the beverage cup 2 through the two holes 15a and 15b without staying on the tip surface 14a of the mouthpiece.

前記飲み口１４は、図１〜図３、図６に示すように、縦壁部１７を有している。縦壁部１７は、基本的に、飲み口先端面１４ａの幅方向外側縁（図２中、先端面１４ａ左側において上下方向に伸びる線）１４ａａから側周壁部５の拡張部５ｂに向けてその先端面１４の周方向の長さを略維持しつつ垂下している一方、縦壁部１７のうち、飲み口先端面１４ａの幅方向外側縁１４ａａに連続する部分１７ａは、飲み口先端面１４ａの幅方向外側縁１４ａａよりも内方側に引っ込むように傾斜されている。これにより、飲み口先端面１４ａと、縦壁部１７のうち、飲み口先端面１４ａの外側縁１４ａａから連続する部分１７ａとは、液切れ構造として、天面板部４の周方向に略一定幅を維持しつつ尖った形状を形成することになり、その尖った形状の先端（飲み口先端面１４ａの幅方向外側縁１４ａａ又は縦壁部１７の上端）では、微視的に、表面張力の作用に基づき、その尖った形状の先端に至った飲料Ｄの液滴１９の粒形化（接触角の増大化）、その増径化が促進されて、その粒形化した液滴１９の重量（Ｍｇ（Ｍ：粒形化した部分の質量、ｇ：重力加速度））は、飲み口先端面１４ａの幅方向外側縁１４ａａ部分での表面張力に基づく引っ張り力（γＬ（γ：表面張力、Ｌ：飲み口先端面１４ａにおける幅方向外側縁１４ａａの周方向の長さ（図５中、直交方向の長さ））に対して早期に打ち勝つことになる。 As shown in FIGS. 1 to 3 and 6, the drinking spout 14 has a vertical wall portion 17. The vertical wall portion 17 basically has a widthwise outer edge of the spout tip surface 14a (a line extending in the vertical direction on the left side of the tip surface 14a in FIG. 2) 14aa toward the expansion portion 5b of the side peripheral wall portion 5. While the tip surface 14 hangs down while substantially maintaining its circumferential length, the portion 17a of the vertical wall portion 17 that is continuous with the widthwise outer edge 14aa of the spout tip surface 14a is the spout tip surface 14a. It is inclined so as to retract inward from the outer edge 14aa in the width direction of the. As a result, the tip surface 14a of the drinking spout and the portion 17a of the vertical wall portion 17 that is continuous from the outer edge 14aa of the tip surface 14a of the drinking spout have a substantially constant width in the circumferential direction of the top plate portion 4 as a liquid drainage structure. A sharp shape will be formed while maintaining the sharp shape, and at the tip of the sharp shape (the outer edge 14aa in the width direction of the spout tip surface 14a or the upper end of the vertical wall portion 17), the surface tension is microscopically increased. Based on the action, the granulation (increasing the contact angle) and the diameter increase of the droplet 19 of the beverage D reaching the tip of the pointed shape are promoted, and the weight of the granulated droplet 19 is promoted. (Mg (M: mass of the granulated portion, g: gravitational acceleration)) is a tensile force based on the surface tension at the outer edge 14aa in the width direction of the spout tip surface 14a (γL (γ: surface tension, L). : The length in the circumferential direction (the length in the orthogonal direction in FIG. 5) of the outer edge 14aa in the width direction on the tip surface 14a of the drinking spout is overcome at an early stage.

他方で、飲料カップ２内の飲料が飲まれないときには、飲み口先端面１４ａでは、前述した如く、飲料（液滴）はへこみ部１６の傾斜により直ちに２つの穴１５ａ、１５ｂを介して飲料カップ２内に導かれることになり、飲み口先端面１４ａには飲料（液滴）は存在しない。このため、飲料Ｄを飲む者が飲み口１４から口を外したときには、同時に、飲み口先端面１４ａの幅方向外側縁１４ａａにおいて、飲料Ｄの液切れが的確に行われ、飲料Ｄの液滴１９が縦壁部１７を伝うような事態の発生を防止できる。 On the other hand, when the beverage in the beverage cup 2 is not drunk, on the drinking spout tip surface 14a, as described above, the beverage (droplet) immediately enters the beverage cup through the two holes 15a and 15b due to the inclination of the dent portion 16. It will be guided into 2, and there is no beverage (droplet) on the tip surface 14a of the drinking spout. Therefore, when the person who drinks the beverage D removes the mouth from the drinking mouth 14, at the same time, the liquid of the beverage D is accurately drained at the outer edge 14aa in the width direction of the tip surface 14a of the drinking mouth, and the droplets of the beverage D are dropped. It is possible to prevent the occurrence of a situation in which 19 travels along the vertical wall portion 17.

尚、飲み口先端面１４ａと、飲み口先端面１４ａの外側縁１４ａａから連続する部分１７ａとが形成する尖った形状の先端部には、図６に示すように、飲料を飲む者の口のつけ易さの観点から、丸みが付けられているが、飲料の液切れ効果を高める観点からは、その丸みを低下させることが好ましい。 As shown in FIG. 6, the pointed tip formed by the spout tip surface 14a and the portion 17a continuous from the outer edge 14a of the spout tip surface 14a is the mouth of a person who drinks a beverage. It is rounded from the viewpoint of ease of application, but it is preferable to reduce the roundness from the viewpoint of enhancing the effect of draining the beverage.

前記縦壁部１７は、図１、図３、図６に示すように、飲み口先端面１４ａの幅方向外側縁１４ａａに連続する部分１７ａに続く部分１７ｂの構成として、下方に向かうに従って先端面１４ａの幅方向外側縁１４ａａよりも外方に向かうように傾斜され、その縦壁部１７の傾斜下端は、側周縁部５の拡張部５ｂに連なっている。これにより、縦壁部１７は、飲み口先端面１４ａの幅方向外側縁１４ａａに連続する部分１７ａと、それに続く部分１７ｂと、その両者１７ａ、１７ｂが形成するへこみ部分１７ｃとを形成することになり、飲料を飲む者の下唇を縦壁部１７に沿わせつつ、上記部分１７ａ，１７ｂ，１７ｃにより、その下唇の移動を抑制できることになる。この結果、飲み口１４に対する飲料を飲む者の口の安定化を図ることができ、飲み易さを高めることができる。 As shown in FIGS. 1, 3, and 6, the vertical wall portion 17 has a tip surface as it goes downward as a configuration of a portion 17b following a portion 17a continuous with the outer edge 14aa in the width direction of the spout tip surface 14a. It is inclined outward from the outer edge 14aa in the width direction of 14a, and the inclined lower end of the vertical wall portion 17 is connected to the expansion portion 5b of the side peripheral edge portion 5. As a result, the vertical wall portion 17 forms a portion 17a continuous with the widthwise outer edge 14aa of the drinking spout tip surface 14a, a portion 17b following the portion 17a, and a dented portion 17c formed by both 17a and 17b. Therefore, while the lower lip of the drinker is aligned with the vertical wall portion 17, the movement of the lower lip can be suppressed by the above portions 17a, 17b, 17c. As a result, it is possible to stabilize the mouth of the person who drinks the beverage with respect to the drinking mouth 14, and it is possible to improve the ease of drinking.

このような飲料容器１に飲料を収容し、そのような複数の飲料容器１を持ち運ぶに際しては、図５に示すように、飲料容器１における蓋３の凹所６に別の飲料容器１の下部２Ｃを嵌合することにより、複数の飲料容器１を安定した状態で積み上げることができる。 When a beverage is stored in such a beverage container 1 and a plurality of such beverage containers 1 are carried, as shown in FIG. 5, the lower portion of another beverage container 1 is placed in the recess 6 of the lid 3 in the beverage container 1. By fitting the 2Cs, a plurality of beverage containers 1 can be stacked in a stable state.

すなわち、当該蓋３においては、積み上げるべき別の飲料容器１（同一下部外径の飲料カップ２）の下部２Ｃを、緩嵌合部８に容易に進入させた上で、密嵌合部９に押し込むことができる。これにより、蓋３における凹所６の密嵌合部９である環状突部（膨出部）を飲料カップ２の底部２Ｂ外周縁部ないし下部２Ｃ外周面により押し退けて（変形させて）（図４参照）、その下部２Ｃ外周面を密嵌合部（環状突部）９に圧着させることができ、飲料カップ２の下部２Ｃは、密嵌合部９に押圧された状態の下で凹所６内に嵌合される（図５参照）。この結果、複数の飲料容器１を安定した状態で積み上げることができ、飲料容器１を手で直接もって運ぶ場合、搬送用具を用いる場合のいずれの場合においても、持ち運ぶことができる飲料容器１の数を増大させて、持ち運ぶことができる飲料容器１の数を効率的に高めることができる。勿論この場合、積み上げた別の飲料容器１の蓋３の凹所６にさらに別の飲料容器１を嵌合することにより飲料容器１の積み上げ数を増大させることができる。 That is, in the lid 3, the lower portion 2C of another beverage container 1 (beverage cup 2 having the same lower outer diameter) to be stacked is easily inserted into the loose fitting portion 8 and then into the tight fitting portion 9. Can be pushed in. As a result, the annular protrusion (bulging portion), which is the tightly fitted portion 9 of the recess 6 in the lid 3, is pushed away (deformed) by the outer peripheral surface of the bottom 2B or the outer peripheral surface of the lower 2C of the beverage cup 2 (FIG. FIG. 4), the outer peripheral surface of the lower portion 2C can be crimped to the tight fitting portion (annular protrusion) 9, and the lower portion 2C of the beverage cup 2 is recessed under the state of being pressed by the tight fitting portion 9. Fitted within 6 (see FIG. 5). As a result, a plurality of beverage containers 1 can be stacked in a stable state, and the number of beverage containers 1 that can be carried regardless of whether the beverage containers 1 are directly carried by hand or when a transport tool is used. Can be increased to efficiently increase the number of beverage containers 1 that can be carried. Of course, in this case, the number of stacked beverage containers 1 can be increased by fitting the other beverage container 1 into the recess 6 of the lid 3 of the other stacked beverage containers 1.

この場合、蓋３における凹所６内に対する飲料カップ下部２Ｃの嵌合度合いの調整に関しては、凹所６内の底部６Ｂと飲料カップ２の底部２Ｂとの当接関係、凹所６の開口６Ａ周縁部と飲料カップ下部２Ｃの外側側面（下部２Ｃとその上側部分との段差部分）の当接、係合関係を、ストッパ手段として利用することができる。 In this case, regarding the adjustment of the degree of fitting of the beverage cup lower portion 2C with respect to the inside of the recess 6 in the lid 3, the contact relationship between the bottom 6B in the recess 6 and the bottom 2B of the beverage cup 2 and the opening 6A of the recess 6 The contact and engagement relationship between the peripheral edge portion and the outer side surface of the lower portion 2C of the beverage cup (the stepped portion between the lower portion 2C and the upper portion thereof) can be used as the stopper means.

またこの場合、天面板部４における飲み口１４の２つの穴１５ａ、１５ｂが並設されていることを利用し、ストローを折り曲げ、その一端側と他端側とを各穴１５ａ、１５ｂに差し込み、その２つの穴１５ａ、１５ｂを塞ぐことが好ましい。飲料が収容された飲料カップ２を持ちながら歩く等の状況において、飲み口１４から外部に飲料がこぼれ散ることを的確に防止できるからである。 Further, in this case, utilizing the fact that the two holes 15a and 15b of the drinking spout 14 in the top plate portion 4 are arranged side by side, the straw is bent and one end side and the other end side thereof are inserted into the respective holes 15a and 15b. , It is preferable to close the two holes 15a and 15b. This is because it is possible to accurately prevent the beverage from spilling from the drinking spout 14 to the outside in a situation such as walking while holding the beverage cup 2 containing the beverage.

前述した如く、飲料カップ２内の飲料を飲む際には、当該蓋３を飲料カップ２の開口周縁部２Ａａから外して、飲料カップ２内の飲料を飲むことができる。この場合、飲料カップ２の下部２Ｃを蓋３の凹所６に嵌合できることを利用して、その蓋３を、図７に示すように、飲料カップ２の底面を拡大するカップ受け（容器受け）又はコースタとして用いることができる。蓋３の側周壁部５における先端部２Ｃが区画する領域の径が凹所６の径（飲料カップ２の底面外径）よりも大きいことから、蓋３の凹所６に飲料カップ２の下部２Ｃを嵌合してその蓋３を介して飲料カップ２をテーブル上面２５に載置したときには、テーブル上面２５に飲料カップ２自体を載置する場合よりも、安定性を高めることができるからである。このため、特に、振動を生じる乗り物である自動車、鉄道車両等において、蓋３を、飲料カップ２の転倒防止を高めるカップ受け又はコースタとして用いることができる。この場合、飲料カップ２の下部２Ｃを蓋３における凹所６の密嵌合部９により一体化した状態で、飲料カップ２内の飲料を飲んだり、飲料カップ２内の飲料を飲む際に、飲料カップ２を蓋３における凹所６から外して使用したりすることができる。 As described above, when drinking the beverage in the beverage cup 2, the lid 3 can be removed from the opening peripheral edge portion 2Aa of the beverage cup 2 to drink the beverage in the beverage cup 2. In this case, utilizing the fact that the lower portion 2C of the beverage cup 2 can be fitted into the recess 6 of the lid 3, the lid 3 is fitted with a cup receiver (container receiver) that enlarges the bottom surface of the beverage cup 2, as shown in FIG. ) Or can be used as a coaster. Since the diameter of the region defined by the tip portion 2C in the side peripheral wall portion 5 of the lid 3 is larger than the diameter of the recess 6 (the outer diameter of the bottom surface of the beverage cup 2), the lower portion of the beverage cup 2 is located in the recess 6 of the lid 3. This is because when the 2C is fitted and the beverage cup 2 is placed on the table upper surface 25 via the lid 3, the stability can be improved as compared with the case where the beverage cup 2 itself is placed on the table upper surface 25. be. Therefore, in particular, in automobiles, railroad vehicles, and the like, which are vehicles that generate vibration, the lid 3 can be used as a cup receiver or coaster that enhances the prevention of the beverage cup 2 from tipping over. In this case, when drinking the beverage in the beverage cup 2 or drinking the beverage in the beverage cup 2 in a state where the lower portion 2C of the beverage cup 2 is integrated by the tightly fitted portion 9 of the recess 6 in the lid 3. The beverage cup 2 can be used by removing it from the recess 6 in the lid 3.

このように蓋３をカップ受け又はコースタとして使用するときには、前述した如く、前記溝１１に基づき、凹所６周壁部（天面板部４）と飲料カップ２の外側側面との間において、複数の排水路１２が形成される。この場合、排水路１２の略半円状の上端開口１３は導入口として機能することになり、飲料カップ２の外側側面に液滴状の結露水１９が生じたときには、その結露水１９は、飲料カップ２の外側側面を伝って落下し、その落下した結露水１９は導入口１３に入り込むことになる（図７参照）。この結果、飲料カップ２の外側側面から結露水１９を排除できると共に、その結露水１９を視認できない状態（凹所６内に収容状態）として、飲料カップ２の使用時の見栄えを向上させることができる。 When the lid 3 is used as a cup receiver or a coaster in this way, as described above, a plurality of portions are provided between the recess 6 peripheral wall portion (top plate portion 4) and the outer side surface of the beverage cup 2 based on the groove 11. The drainage channel 12 is formed. In this case, the substantially semi-circular upper end opening 13 of the drainage channel 12 functions as an introduction port, and when droplet-shaped dew water 19 is generated on the outer side surface of the beverage cup 2, the dew water 19 becomes the dew water 19. It falls along the outer side surface of the beverage cup 2, and the dropped dew condensation water 19 enters the introduction port 13 (see FIG. 7). As a result, the dew condensation water 19 can be removed from the outer side surface of the beverage cup 2, and the dew condensation water 19 can be invisible (contained in the recess 6) to improve the appearance of the beverage cup 2 when used. can.

また、この蓋３をカップ受け又はコースタとして使用するときには、図７に示すように、側周縁部５における先端部５ａのきわめて細い端面だけが伝導面積としてテーブル上面２５に当接し、テーブル上面と蓋３の裏面との間には断熱層としての空気層２６が介在されることになる。これにより、飲料カップ２内の飲食物の温度が変化することを抑制できることになる。 Further, when the lid 3 is used as a cup receiver or a coaster, as shown in FIG. 7, only the extremely thin end surface of the tip portion 5a of the side peripheral edge portion 5 abuts on the table upper surface 25 as a conduction area, and the table upper surface and the lid. An air layer 26 as a heat insulating layer is interposed between the back surface of the third layer. This makes it possible to suppress changes in the temperature of food and drink in the beverage cup 2.

図８は第２実施形態を示す。この各第２施形態において、前記第１実施形態と同一構成要素については同一符号を付してその説明を省略する。 FIG. 8 shows a second embodiment. In each of the second embodiments, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

図８に示す第２実施形態は、蓋２の凹所６が、下部外径が異なる２種類の飲料カップ２を嵌合できるようにしたものを示す。この第２実施形態においては、凹所６の内周壁７が、その凹所６の底部６Ｂから開口２Ａに向けて段階的に拡径されることにより、内径が異なった下段側内周壁部２０と上段側内周壁部２１とをもって形成され、その下段側内周壁部２０と上段側内周壁部２１との間には段差部２２が形成されている。下段側内壁部２０は、蓋３が用いられる飲料カップ２の下部２Ｃ外径と同じ飲料カップ２−１の下部２Ｃを嵌合できる内径とされ、上段側内壁部２１は、上記飲料カップ２の下部２Ｃ外径よりも大きい飲料カップ２−２の下部２Ｃを嵌合できる内径とされている。この場合の各内周壁部２０，２１と、それに対応する飲料カップ２−１，２−２の下部２Ｃとの嵌合度合いは、密嵌合に限らず、安定性が確保されている限り、多少、緩くした嵌合状態であってもよい。 The second embodiment shown in FIG. 8 shows a recess 6 of the lid 2 capable of fitting two types of beverage cups 2 having different lower outer diameters. In this second embodiment, the inner peripheral wall 7 of the recess 6 is gradually expanded from the bottom 6B of the recess 6 toward the opening 2A, so that the inner peripheral wall portion 20 on the lower stage side has a different inner diameter. And the upper inner peripheral wall portion 21, and a stepped portion 22 is formed between the lower inner peripheral wall portion 20 and the upper inner peripheral wall portion 21. The lower inner wall portion 20 has an inner diameter that allows the lower portion 2C of the beverage cup 2-1 having the same outer diameter as the lower 2C outer diameter of the beverage cup 2 in which the lid 3 is used to be fitted, and the upper inner wall portion 21 is the beverage cup 2 having the same inner diameter. The inner diameter is set so that the lower 2C of the beverage cup 2-2, which is larger than the outer diameter of the lower 2C, can be fitted. In this case, the degree of fitting between the inner peripheral wall portions 20 and 21 and the corresponding lower portions 2C of the beverage cups 2-1 and 2-2 is not limited to tight fitting, as long as stability is ensured. It may be in a slightly loosely fitted state.
