Description

本発明はペットボトル等の飲料容器の改良に関し、特に液体を収容した状態で冷凍庫内に横置き保管するのに適した構造を備えたボトル容器に関する。   The present invention relates to an improvement of a beverage container such as a plastic bottle, and more particularly to a bottle container having a structure suitable for horizontal storage in a freezer while containing a liquid.

ペットボトルを始めとしたボトル容器は縦置きに適した形状を備え、飲み口、注ぎ口としての開口部が容器本体の上方に一箇所設けられ、この開口部をキャップによって開閉するように構成しているのが普通である。このようなボトル容器内から収容物を注出したり、ボトル容器ごと冷蔵庫等に縦置き保管する場合には、従来の開口部の構造によって支障が生じることは少なかった。   Bottle containers such as plastic bottles have a shape suitable for vertical installation, and an opening as a drinking and pouring opening is provided at one location above the container body, and this opening is configured to be opened and closed by a cap. It is normal. In the case where the contents are poured out from such a bottle container or stored vertically in the refrigerator or the like together with the bottle container, there are few problems caused by the structure of the conventional opening.

一方、夏期においては、家庭や販売店において、飲料を収容したペットボトルを冷凍庫内に保管して飲料を凍結させておくことにより、長時間に渡って冷たさを維持できるようにした利用方法が多用される。この場合、飲料凍結による体積膨張に起因した容器の破損を防止するためにキャップを外して開口部を開放しておく等の対応が必要であるが、開口部がボトル本体の上部にあるため、キャップを外した状態での液漏れを防止する必要から、縦置き状態でしか冷凍庫内に保管することができなかった。しかし、一般の家庭用冷蔵庫が備える冷凍庫の高さ寸法は、５００ｍｌ程度のペットボトルを縦置きするのには不十分であるため、冷凍庫内にペットボトルを横置きするためには、飲料の凍結による体積膨張分を配慮してキャップをわざわざ開封して予め収容した飲料の量を減少させておく等の手間がかかった。また、縦置きが可能な高さ寸法を有した業務用の冷凍庫にあっても他の収納物との位置関係や、設置安定性を考えた場合にペットボトル類は横置き、横積みした方が便利な場合が多いが、販売用の飲料を収容した未開封のペットボトルを冷凍保存する際にキャップを開封して飲料の量を減ずることは不可能である。   On the other hand, in summer, there is a usage method that can keep cold for a long time by storing PET bottles containing beverages in a freezer and freezing the beverages at home and at retail stores. Often used. In this case, in order to prevent breakage of the container due to volume expansion due to freezing of the beverage, it is necessary to take measures such as removing the cap and opening the opening, but the opening is at the top of the bottle body, Since it was necessary to prevent liquid leakage when the cap was removed, it could only be stored in the freezer vertically. However, the height of the freezer provided in a general household refrigerator is insufficient to place a plastic bottle of about 500 ml vertically, so that it is necessary to freeze the beverage in order to place the plastic bottle horizontally in the freezer. Taking into account the volume expansion due to the above, it took time and effort to open the cap and reduce the amount of beverage stored in advance. In addition, even in a commercial freezer with a height that can be placed vertically, when considering the positional relationship with other storage items and installation stability, PET bottles should be placed horizontally and stacked horizontally In many cases, however, it is impossible to reduce the amount of beverage by opening the cap when the unopened PET bottle containing the beverage for sale is stored frozen.

実用新案登録第３０８１６５７号には、ペットボトル内に収容した水の氷結膨張率を考慮した水の収容限度表示をペットボトルの首部に表示した凍結用水収容限度表示付きペットボトルが開示されている。しかし、この従来例のペットボトル内に水を収容して冷凍庫内で保管する場合、ボトル内に収容する水量を予め満杯状態よりも減少させておく必要があり煩雑であるばかりでなく、収容する水量が減少するため飲用に供し得る水量が少なくなるという問題がある。
実用新案登録第３０８１６５７号 特開２００３−１９２０４４公報 Utility Model Registration No. 3086657 discloses a plastic bottle with a freezing water storage limit display in which a water storage limit display in consideration of the rate of freezing and expansion of water stored in a plastic bottle is displayed on the neck of the plastic bottle. However, when water is stored in the conventional plastic bottle and stored in the freezer, the amount of water stored in the bottle needs to be reduced in advance from the full state, and is not only complicated but also stored. Since the amount of water decreases, there is a problem that the amount of water available for drinking is reduced.

このように従来、飲料を収容したペットボトル等のボトル容器を冷凍庫内に冷凍保管する際に、ボトル容器を横置きにして収容したいという要請が強いにも拘わらず、横置きにする場合にはボトル上部に設けた開口部からの内容物の流出を避けるために開口部を開放状態にすることができず、その結果飲料の凍結膨張によって容器が破損し易くなるという問題があった。
本発明は上記に鑑みてなされたものであり、ペットボトル等の飲料容器内に飲料等の液体を収容した状態で冷凍庫内に横置き保管して液体を凍結させたとしても、凍結膨張によって容器が破損することがないボトル容器を提供することを目的としている。 As described above, when a bottle container such as a plastic bottle containing a beverage is stored in a freezer in a freezer, the bottle container is placed horizontally although there is a strong demand for storing the bottle container horizontally. In order to avoid the outflow of the contents from the opening provided in the upper part of the bottle, the opening cannot be opened, and as a result, there has been a problem that the container is easily damaged by freezing and expansion of the beverage.
The present invention has been made in view of the above, and even if a liquid such as a beverage is accommodated in a beverage container such as a plastic bottle, the container can be stored by freezing and expanding in a freezer. It aims to provide a bottle container that will not break.

上記目的を達成するため、請求項１の発明は、縦置き時における設置面となる底面を備えた中空の容器本体と、該容器本体の上部に位置し且つ該容器本体の中空内部と連通した第１の開口部と、を備えたボトル容器において、前記容器本体の側面に該容器本体の中空内部と連通した第２の開口部を設けたことを特徴とする。
縦置きに適した構造を備えたボトル容器を横置きにして内部液体を冷凍する場合には、液体の体積膨張による容器本体の破損や開口部からの液漏れを考慮して予め液量を減少させる等の手間が必要であった。本発明では、容器本体側面に第２の開口部を設け、この第２の開口部を上向きにして横置きに保管することにより、液漏れを防ぎつつ体積膨張による不具合を解消することができる。 In order to achieve the above object, the invention of claim 1 is characterized in that a hollow container body provided with a bottom surface serving as an installation surface when placed vertically, and located above the container body and communicated with the hollow interior of the container body. A bottle container having a first opening is characterized in that a second opening communicating with the hollow interior of the container body is provided on a side surface of the container body.
When freezing the internal liquid by placing a bottle container with a structure suitable for vertical installation in a horizontal position, reduce the liquid volume in advance in consideration of damage to the container body due to volume expansion of the liquid and liquid leakage from the opening. It took time and effort. In the present invention, the second opening is provided on the side surface of the container main body, and the second opening is stored in the horizontal position with the second opening facing upward, whereby the problem due to volume expansion can be solved while preventing liquid leakage.

請求項２の発明は、請求項１において、前記第１の開口部を開閉する蓋部材を備え、前記第２の開口部は前記蓋部材と同形状の蓋部材を装着可能な装着部を備えていることを特徴とする。
第１と第２の開口部を開閉する蓋部材として共通の形状、サイズのものを使用できるので、製品コストを下げ、量産性を向上することができる。 According to a second aspect of the present invention, in the first aspect, the first opening includes a lid member that opens and closes the first opening, and the second opening includes a mounting portion on which a lid member having the same shape as the lid member can be mounted. It is characterized by.
Since the same shape and size can be used as the lid member for opening and closing the first and second openings, the product cost can be reduced and the mass productivity can be improved.

請求項３の発明は、請求項１又は２において、前記第１の開口部は、前記容器本体の上部に位置し且つ該容器本体の中空内部と連通した中空筒状の第１のネック部の端部に形成され、前記第２の開口部は、前記容器本体の側面に突設されて該容器本体の中空内部と連通した中空筒状の第２のネック部の端部に形成されていることを特徴とする。
容器本体の上部のみならず、側面にもネック部を設けているので、この第２のネック部内に形成される余剰空間が収容した液体の体積膨張分を吸収する。従って、第２のネック部先端に設けた第２の開口部を蓋部材によって閉じたままであってもある程度体積膨張による応力を緩和することができる。 According to a third aspect of the present invention, in the first or second aspect of the present invention, the first opening is a hollow cylindrical first neck portion that is located at an upper portion of the container body and communicates with a hollow interior of the container body. The second opening is formed at an end portion, and is formed at an end portion of a hollow cylindrical second neck portion that protrudes from a side surface of the container body and communicates with a hollow interior of the container body. It is characterized by that.
Since the neck portion is provided not only on the upper portion of the container body but also on the side surface, the volume expansion of the liquid stored in the surplus space formed in the second neck portion is absorbed. Therefore, the stress due to volume expansion can be relieved to some extent even when the second opening provided at the tip of the second neck portion remains closed by the lid member.

請求項４の発明は、請求項２又は３において、前記容器本体の底面には、他の同形状のボトル容器に装着した前記蓋部材の少なくとも一部を嵌合可能な底面凹所を備えていることを特徴とする。
このボトル容器を縦置き状態で上下方向に縦積みする場合には、上部蓋部材が上側のボトル容器の底面凹所内に嵌合するので、安定した縦積み状態を実現できる。また、一方のボトル容器の底面に他のボトル容器の側面に突設した蓋部材を嵌合させることも可能である。 According to a fourth aspect of the present invention, in the second or third aspect of the present invention, the bottom surface of the container body is provided with a bottom recess capable of fitting at least a part of the lid member attached to another bottle container having the same shape. It is characterized by being.
When the bottle containers are vertically stacked in a vertically placed state, the upper lid member is fitted in the bottom recess of the upper bottle container, so that a stable vertically stacked state can be realized. It is also possible to fit a lid member protruding from the side surface of another bottle container to the bottom surface of one bottle container.

請求項５の発明は、請求項２又は３において、前記容器本体の側面には、他の同形状のボトル容器に装着した前記蓋部材の少なくとも一部を嵌合可能な側面凹所を備えていることを特徴とする。
このボトル容器を横置き状態で上下位置関係で重ねて積む場合には、一方のボトル容器の側面に突設した蓋部材が上側のボトル容器の側面に設けた側面凹所内に嵌合するので、安定した横積み状態を実現できる。また、一方のボトル容器の側面凹所内に他のボトル容器の上部蓋部材を嵌合させることも可能である。 According to a fifth aspect of the present invention, in the second or third aspect, the side surface of the container body is provided with a side recess into which at least a part of the lid member attached to another bottle container having the same shape can be fitted. It is characterized by being.
When stacking this bottle container in a horizontal position in a vertical position, the lid member protruding from the side surface of one bottle container fits into the side recess provided on the side surface of the upper bottle container. A stable horizontal stack can be achieved. It is also possible to fit the upper lid member of another bottle container into the side recess of one bottle container.

請求項６の発明は、請求項１乃至５の何れか一項において、前記第２の開口部の開口面積は、前記第１の開口部の開口面積よりも小さいことを特徴とする。
両開口部における蓋部材の装着部は同一形状、同一寸法となっているので、蓋部材を共通使用できるが、各開口部の用途は夫々異なる。第１の開口部は飲み口、或いは注ぎ口として機能するためある程度の開口面積の広さを確保する必要がある一方で、第２の開口部は空気穴、或いは内圧上昇回避用の穴として機能するため、極力小さな開口面積があれば十分である。また、冷蔵庫内における保存時の状況を考慮した場合にも、開口面積が小さい方が振動や膨張を原因とした液の漏れ出しの発生を有効に防止する上で有効である。 According to a sixth aspect of the present invention, in any one of the first to fifth aspects, an opening area of the second opening is smaller than an opening area of the first opening.
Since the mounting portions of the lid members in both openings have the same shape and the same dimensions, the lid members can be used in common, but the use of each opening is different. Since the first opening functions as a drinking mouth or a spout, it is necessary to secure a certain amount of opening area, while the second opening functions as an air hole or a hole for avoiding an increase in internal pressure. Therefore, it is sufficient that the opening area is as small as possible. In consideration of the situation during storage in the refrigerator, a smaller opening area is effective in effectively preventing the occurrence of liquid leakage due to vibration and expansion.

請求項７の発明は、請求項５又は６において、前記第２の開口部と前記側面凹所は、前記容器本体の側面に対向配置されていることを特徴とする。
第２の開口部と側面凹所の周方向位置が１８０度ずれた状態で対向しているので、各ボトル容器を平行に近接配置した場合に、一方のボトル容器の第２の開口部が隣接する他のボトル容器の側面凹所内に嵌合することができる。この際、各ボトル容器の第２の開口部の方向を同一方向とすることができるので、複数のボトル容器を冷凍庫内に横置き状態で積載する際に便利である。 A seventh aspect of the invention is characterized in that, in the fifth or sixth aspect, the second opening and the side recess are opposed to the side surface of the container body.
Since the circumferential direction position of the second opening and the side recess is shifted by 180 degrees, when each bottle container is arranged close to each other in parallel, the second opening of one bottle container is adjacent It can fit into the side recess of other bottle containers. At this time, the direction of the second opening of each bottle container can be the same direction, which is convenient when loading a plurality of bottle containers in a freezer in a horizontally placed state.

請求項８の発明は、請求項７において、前記第２の開口部と対向する前記容器本体側面には、設置安定用の平坦面が面取り形成されていることを特徴とする。
第２の開口部を上向きにして横置きする際に、反対側の側面が平坦面であることにより横置き時の設置安定性を高めることが可能となる。 The invention of claim 8 is characterized in that, in claim 7, a flat surface for installation stabilization is chamfered on the side surface of the container body facing the second opening.
When placing the second opening portion upward, the installation stability during the transverse placement can be enhanced by the fact that the opposite side surface is a flat surface.

以上のように本発明においては、縦置き時における設置面となる底面を備えた中空の容器本体と、該容器本体の上部に位置し且つ該容器本体の中空内部と連通した第１の開口部と、を備えたボトル容器において、容器本体の側面に該容器本体の中空内部と連通した第２の開口部を設け、各開口部を同一構造の蓋部材により開閉できるように構成したので、ペットボトル等の飲料容器内に飲料等の液体を収容した状態で冷凍庫内に横置き保管して液体を凍結させたとしても、凍結膨張によって容器が破損することを防止できる。   As described above, in the present invention, a hollow container body having a bottom surface serving as an installation surface during vertical installation, and a first opening located at the upper part of the container body and communicating with the hollow interior of the container body In the bottle container provided with the second opening portion communicated with the hollow interior of the container body on the side surface of the container body, and each opening portion can be opened and closed by the lid member having the same structure. Even when a liquid such as a beverage is accommodated in a beverage container such as a bottle and stored horizontally in a freezer to freeze the liquid, the container can be prevented from being damaged by freezing and expansion.

以下、本発明を図面に示した実施の形態により詳細に説明する。
図１は本発明の一実施形態に係るボトル容器の構成を示す正面図であり、図２（ａ）乃至（ｅ）はこのボトル容器の正面図、左側面図、右側面図、平面図、及び底面図であり、図３（ａ）及び（ｂ）は各開口部の開口面積を示す図であり、図４（ａ）（ｂ）及び（ｃ）は蓋部材の正面図、平面図、及び底面図であり、図５はボトル容器同士を連結した状態を示す図である。
このボトル容器１は、例えばＰＥＴ（ポリエチレンテレフタレート）から成る所謂ペットボトルであり、水平面上に設置可能な底面３を備えた中空の容器本体２と、容器本体２の上部に位置し且つ容器本体の中空内部と連通した第１の開口部２０と、第１の開口部２０に着脱自在に装着されてこれを開閉する蓋部材４０と、を備える。 Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is a front view showing the configuration of a bottle container according to an embodiment of the present invention, and FIGS. 2A to 2E are a front view, a left side view, a right side view, a plan view of the bottle container, FIGS. 3A and 3B are views showing the opening area of each opening, and FIGS. 4A, 4B, and 4C are a front view, a plan view, and a lid member, respectively. 5 is a bottom view, and FIG. 5 is a view showing a state where the bottle containers are connected to each other.
The bottle container 1 is a so-called PET bottle made of, for example, PET (polyethylene terephthalate), and has a hollow container body 2 having a bottom surface 3 that can be set on a horizontal surface, and an upper portion of the container body 2 and the container body 2. A first opening 20 that communicates with the hollow interior, and a lid member 40 that is detachably attached to the first opening 20 to open and close it.

本発明に係るボトル容器１の特徴的な構成は、容器本体２の側面（外周面）の適所に容器本体の中空内部と連通した第２の開口部３０を設けた点と、第２の開口部３０に着脱自在に装着されてこれを開閉する蓋部材４０を設けた点にある。
容器本体２の底面形状は図２（ｅ）に示したように四角形（多角形）であってもよいし、円形、その他の任意の形状であってもよい。容器本体を構成する材質は、ＰＥＴのような樹脂であっても良いし、金属であってもよい。
底面３は水平面に設置したときにボトル容器１を安定して縦置きできるように構成されている。
容器本体２の上部には中空筒状（円筒状）の第１のネック部５が突出しており、第１のネック部５の上端開口（第１の開口部２０）を開閉するための蓋部材（キャップ）４０が第１のネック部５の外周の雄ねじ部５ａに螺着される。蓋部材４０の内壁面には雄ねじ部５ａと螺着する雌ねじ部４０ａが形成されている。 The characteristic configuration of the bottle container 1 according to the present invention is that a second opening 30 communicating with the hollow interior of the container body is provided at an appropriate position on the side surface (outer peripheral surface) of the container body 2, and the second opening A lid member 40 that is detachably attached to the part 30 and opens and closes the part 30 is provided.
The bottom shape of the container body 2 may be a quadrangle (polygon) as shown in FIG. 2 (e), a circle, or any other shape. The material constituting the container body may be a resin such as PET or a metal.
The bottom surface 3 is configured so that the bottle container 1 can be placed vertically stably when installed on a horizontal surface.
A hollow tubular (cylindrical) first neck portion 5 projects from the upper portion of the container body 2, and a lid member for opening and closing the upper end opening (first opening portion 20) of the first neck portion 5. A (cap) 40 is screwed onto the external thread portion 5 a on the outer periphery of the first neck portion 5. On the inner wall surface of the lid member 40, a female screw portion 40a that is screwed to the male screw portion 5a is formed.

また、容器本体２の側面適所には、中空筒状（円筒状）の第２のネック部１０が突出しており、第２のネック部１０の先端開口（第２の開口部３０）を開閉するための蓋部材（キャップ）４０が第２のネック部１０の外周の雄ねじ部（装着部）１０ａに螺着される。この蓋部材４０の形状、寸法等の構成は上記蓋部材と同じであり、内壁面には雄ねじ部１０ａと螺着する雌ねじ部４０ａが形成されている。
従って、蓋部材４０は同一形状のものを、各開口部２０、３０を開閉する手段として共通使用することができる。 In addition, a hollow cylindrical (cylindrical) second neck portion 10 protrudes at an appropriate position on the side surface of the container body 2, and opens and closes the tip opening (second opening portion 30) of the second neck portion 10. A lid member (cap) 40 for this purpose is screwed to the external thread portion (mounting portion) 10 a on the outer periphery of the second neck portion 10. The configuration of the lid member 40, such as shape and dimensions, is the same as that of the lid member, and an internal thread portion 40a that is screwed to the external thread portion 10a is formed on the inner wall surface.
Therefore, the lid member 40 having the same shape can be commonly used as a means for opening and closing the openings 20 and 30.

各ネック部５、１０の外形寸法（装着部寸法）は、同一形状の蓋部材４０を装着できるようにほぼ同様に構成されているが、各ネック部５、１０に設けた各開口部２０、３０の開口面積は、飲料を取り出すための第１の開口部２０の方が、第２の開口部３０よりも大きく設定されている。即ち、ボトル容器１を冷凍庫内に横置きする際には、第２のネック部１０、即ち第２の開口部３０が上方を向くように載置する。そして、第２の開口部３０に取り付ける蓋部材４０を外すか、或いは緩めることにより、第２の開口部３０を外部空気と連通させて、凍結により体積膨張した飲料が第２のネック部１０内に入り込むことができるようにする為のものである。この結果、容器本体が密閉された閉空間である場合に、凍結して体積膨張した飲料によって容器本体の側壁、その他の部位が破断する事態が防止される。このような第２の開口部３０の機能を発揮させるためには、その開口面積は必要最小限であればよく、必要十分な量の飲料を取り出すことができる程の大きな開口面積は不要である。   The external dimensions (mounting portion dimensions) of the neck portions 5 and 10 are configured in substantially the same manner so that the lid member 40 having the same shape can be mounted, but the opening portions 20 provided in the neck portions 5 and 10, The opening area of 30 is set to be larger in the first opening 20 for taking out the beverage than in the second opening 30. That is, when the bottle container 1 is placed horizontally in the freezer, the second neck 10, that is, the second opening 30 is placed so as to face upward. Then, by removing or loosening the lid member 40 attached to the second opening 30, the second opening 30 is brought into communication with the external air, and the beverage volume-expanded by freezing is contained in the second neck 10. It is to be able to get in. As a result, when the container body is a closed space, the side wall of the container body and other parts are prevented from being broken by the frozen and volume-expanded beverage. In order to exhibit the function of the second opening portion 30 as described above, the opening area only needs to be the minimum necessary, and a large opening area capable of taking out a necessary and sufficient amount of beverage is not necessary. .

即ち、両開口部２０、３０における蓋部材の装着部は同一形状、同一寸法となっているので、蓋部材を共通使用できるが、各開口部の用途は夫々異なる。第１の開口部２０は飲み口、或いは注ぎ口として機能するためある程度の開口面積の広さを確保する必要がある一方で、第２の開口部３０は空気穴、或いは内圧上昇回避用の穴として機能するため、極力小さな開口面積があれば十分である。また、冷蔵庫内における保存時の状況を考慮した場合にも、開口面積が小さい方が振動や膨張を原因とした液の漏れ出しの発生を有効に防止する上で有効である。   That is, since the mounting portions of the lid members in both the openings 20 and 30 have the same shape and the same dimensions, the lid members can be used in common, but the uses of each opening are different. Since the first opening 20 functions as a drinking mouth or a spout, it is necessary to secure a certain amount of opening area, while the second opening 30 is an air hole or a hole for avoiding an increase in internal pressure. Therefore, it is sufficient that the opening area is as small as possible. In consideration of the situation during storage in the refrigerator, a smaller opening area is more effective in effectively preventing the occurrence of liquid leakage due to vibration and expansion.

なお、蓋部材４０により第２の開口部３０を密封したままであったとしても第２のネック部１０の内部空間に体積膨張した飲料が入り込むことによりその分だけ容器本体内壁に対して凍結飲料から加わる圧力が低減するため、容器の破損が防止される。従って、第２のネック部１０内の余剰空間の容積を大きく確保するように配慮してもよい。
なお、ネック部５、１０のような突出部の先端に設けた開口部ではなく、容器本体外面に設けた単なる開口部に蓋部材４０を何らかの着脱手段によって着脱することにより各開口部を開閉するように構成してもよい。
以上の構成を備えたボトル容器を冷凍庫内に横置きする場合には、第２の開口部３０が上を向くように横臥させる一方で、第２の開口部を封止する蓋部材４０を取り外すか、或いは緩めておく。この状態でボトル容器内の飲料が凍結して体積膨張したとしても、第２の開口部３０側に膨張した飲料の一部が入り込むことができるため、容器本体内壁が過大な圧力により破損することが防止される。 Even if the second opening 30 is still sealed by the lid member 40, the frozen beverage is applied to the inner wall of the container main body by the amount of the volume-expanded beverage entering the internal space of the second neck portion 10. Since the pressure applied from the container is reduced, the container is prevented from being damaged. Therefore, you may consider so that the volume of the surplus space in the 2nd neck part 10 may be ensured large.
Note that each opening is opened / closed by attaching / detaching the lid member 40 to / from a simple opening provided on the outer surface of the container main body, instead of the opening provided at the tip of the protruding portion such as the neck portions 5 and 10. You may comprise as follows.
When the bottle container having the above configuration is placed horizontally in the freezer, the lid member 40 that seals the second opening is removed while the second opening 30 is laid down so that the second opening 30 faces upward. Or loosen. Even if the beverage in the bottle container freezes and expands in volume in this state, a part of the expanded beverage can enter the second opening 30 side, so that the inner wall of the container body is damaged by excessive pressure. Is prevented.

次に、容器本体２の側面に第２のネック部１０及び蓋部材４０が突出しているボトル容器１を複数個、縦置き、或いは横置き状態で近接配置して梱包したり、保管する場合に、この突出部が邪魔となって容器本体間を近接させて配列すること困難となる。
そこで本発明のボトル容器１では、容器本体２の側面に、他の同形状のボトル容器の第１のネック部５、及び／或いは、第２のネック部１０に装着した蓋部材４０を嵌合可能な側面凹所１１を設けている。側面凹所１１の縦寸法Ｌ１は他のボトル容器の第２のネック部及び蓋部材を嵌合するのに十分な寸法を有するが、深さＬ２は図５に示したように突出部全体を嵌合し得るように構成してもよいし、その一部だけを収容し得るように構成してもよい。図示のように第２のネック部１０と蓋部材４０から成る突出部を完全に収納し得る程度に深さＬ２を大きくした場合には隣接し合う容器本体１の側面同士を密着させることができるので、梱包や保管のための収納空間を節約できるメリットが得られる。しかも、縦置きのみならず、横置きする場合においても同様のメリットが得られる。 Next, when packing or storing a plurality of bottle containers 1 in which the second neck portion 10 and the lid member 40 protrude on the side surface of the container body 2 are arranged in a vertical or horizontal position in close proximity. This protrusion becomes an obstacle, making it difficult to arrange the container bodies close to each other.
Therefore, in the bottle container 1 of the present invention, the lid member 40 attached to the first neck part 5 and / or the second neck part 10 of another bottle container of the same shape is fitted to the side surface of the container body 2. Possible side recesses 11 are provided. The vertical dimension L1 of the side recess 11 is sufficient to fit the second neck portion and the lid member of another bottle container, but the depth L2 is the entire protrusion as shown in FIG. You may comprise so that it may fit, and it may comprise so that only the one part can be accommodated. As shown in the figure, when the depth L2 is increased to such an extent that the protruding portion composed of the second neck portion 10 and the lid member 40 can be completely accommodated, the side surfaces of the adjacent container bodies 1 can be brought into close contact with each other. Therefore, the merit which can save the storage space for packing and storage is acquired. Moreover, the same merit can be obtained not only in the vertical placement but also in the horizontal placement.

冷凍庫内に横置き状態で積層収納する場合には、図５に示すように側面の突出部を側面凹所１１内に嵌合させる前に、蓋部材４０を緩めて第２の開口部３０を開放しておくことにより、内部飲料の凍結による体積膨張に起因した不具合を解消できる。
なお、この実施形態では、側面凹所１１を第２の開口部３０（第２のネック部１０）と対向する位置に設けたが、側面凹所の形成位置はこの対向位置に限る訳ではなく、開口部３０と高さレベルが同じ他の部位（例えば、周方向位置が９０度ずれた位置）に設けたり、或いは開口部３０の高さ位置と異なる位置に側面凹所１１を設けても良い。但し、第２の開口部３０と側面凹所１１とを対向配置した場合には、第２の開口部３０を上向きにした横置き状態で多数のボトル容器１を密着配列させて冷凍保管することが可能となる。
更に、容器本体２の底面に、隣接する他の同形状のボトル容器の第１又は第２のネック部５、１０に装着した蓋部材４０を嵌合可能な底面凹所１５を設けても良い。図示の例では、底面凹所１５はネック部及び蓋部材から成る突出部全体を嵌合し得る深さ寸法を有していないが、突出部全体を嵌合し得る深さ寸法を有する構成としてもよい。 When stacking and storing horizontally in the freezer, the lid member 40 is loosened and the second opening 30 is opened before the side protrusion is fitted into the side recess 11 as shown in FIG. By opening it, problems caused by volume expansion due to freezing of the internal beverage can be solved.
In this embodiment, the side recess 11 is provided at a position facing the second opening 30 (second neck 10), but the position at which the side recess is formed is not limited to this facing position. Even if the opening 30 is provided at another part having the same height level (for example, a position where the circumferential position is shifted by 90 degrees), or the side recess 11 is provided at a position different from the height of the opening 30 good. However, when the second opening 30 and the side recess 11 are arranged to face each other, a large number of bottle containers 1 are arranged in close contact with the second opening 30 facing upward and stored frozen. Is possible.
Furthermore, a bottom surface recess 15 into which the lid member 40 attached to the first or second neck portion 5 or 10 of another adjacent bottle container having the same shape may be provided on the bottom surface of the container body 2. . In the illustrated example, the bottom recess 15 does not have a depth dimension capable of fitting the entire protrusion including the neck portion and the lid member, but has a depth dimension capable of fitting the entire protrusion. Also good.

図２に示した実施形態に係るボトル容器のように容器本体の外形が略四角柱状である場合には、第２の開口部３０と対向する容器側面が平坦面となっているために冷凍庫内の水平面上に横置きした際における設置安定性を確保することができる。一方、容器本体を円筒状に構成した場合、第２の開口部３０を上向きにして水平面上に横置きすると設置安定性を確保できず回転して、第２の開口部３０が下方へ変位して凍結前の飲料が漏れ出る虞もある。そこで、容器本体の周面が円筒状である場合には、第２の開口部３０と対向する反対側の側面の一部を平坦面状に面取りすることにより、設置安定性を確保するのが好ましい。   In the case where the outer shape of the container body is a substantially quadrangular prism shape like the bottle container according to the embodiment shown in FIG. 2, since the container side surface facing the second opening 30 is a flat surface, the inside of the freezer The installation stability when placed horizontally on the horizontal plane can be ensured. On the other hand, when the container main body is configured in a cylindrical shape, if the container is placed on a horizontal surface with the second opening 30 facing upward, the installation stability cannot be secured and the second opening 30 is displaced downward. There is also a risk that the beverage before freezing will leak. Therefore, when the peripheral surface of the container body is cylindrical, it is possible to ensure installation stability by chamfering a part of the opposite side surface facing the second opening 30 to a flat surface. preferable.

なお、特許文献２には、複数のペットボトルを連結するために、ボトル底面に凹部を設けて他のボトルの頂部のキャップを嵌合させるように構成すると共に、ボトル側面にもキャップを突設するように構成する一方で、ボトル側面のキャップの反対側側面に他のボトルのキャップが嵌合する凹部を設けた構成が開示されている。
しかし、この工法には、ボトル側面に設けたキャップと、他のペットボトルのキャップを嵌合する凹部については開示されているが、ボトル側面に開口部を設けることと、この開口部をキャップにより開閉する構成については一切開示されていない。従って、この従来例によれば、ボトルを横置きした場合に内部飲料を漏出させることなく、凍結飲料の体積膨張に起因した不具合を解決することはできない。
なお、本発明は、ペットボトルのみならず、多用なタイプのボトル容器に適用することができる。 In Patent Document 2, in order to connect a plurality of PET bottles, a concave portion is provided on the bottom surface of the bottle and a cap at the top of another bottle is fitted, and a cap is also provided on the side surface of the bottle. On the other hand, the structure which provided the recessed part which the cap of another bottle fits in the other side surface of the cap of the bottle side surface is disclosed.
However, although this method discloses a cap provided on the side of the bottle and a recess for fitting the cap of another PET bottle, an opening is provided on the side of the bottle, and this opening is provided by the cap. There is no disclosure of a configuration for opening and closing. Therefore, according to this conventional example, it is not possible to solve the problems caused by the volume expansion of the frozen beverage without leaking the internal beverage when the bottle is placed horizontally.
The present invention can be applied not only to PET bottles but also to various types of bottle containers.
