キャップ６は、その内側面６ａから突出して、キャップ６が閉じた状態で弾性部材５の通気穴１５内に挿入されて、通気穴１５を覆う弁板部１６を開放する開放凸部６ｃを有する。通気穴１５の弁板部１６が開放されることにより、容器本体２の内圧が上昇して飲み口部２０から飲料が漏れ出る、ということが防止される。 The cap 6 has an open convex portion 6c that protrudes from the inner side surface 6a and is inserted into the ventilation hole 15 of the elastic member 5 in a state where the cap 6 is closed to open the valve plate portion 16 that covers the ventilation hole 15. .. By opening the valve plate portion 16 of the ventilation hole 15, it is possible to prevent the internal pressure of the container body 2 from rising and the beverage from leaking from the drinking spout portion 20.

ところで、容器本体と容器本体に取り外し可能に取り付けられる飲み口アダプターとを有する飲料容器においては、飲み口アダプターを容器本体に取り付ける際、飲み口アダプターと容器本体との間から飲料が漏れ出ることを防止するため、飲み口アダプターと容器本体とを密着させて、両者の間にシールを形成する必要がある。これには大きな力を要し、飲料容器の取り扱い性を損なっていた。また、飲み口アダプターと容器本体とを互いに対してしっかりと押し付けても、飲み口アダプターには製造誤差等により個体差が生じるため、飲み口アダプターと容器本体との間に安定してシールを形成することは困難であった。 By the way, in a beverage container having a container body and a mouthpiece adapter that can be detachably attached to the container body, when the mouthpiece adapter is attached to the container body, the beverage may leak from between the mouthpiece adapter and the container body. To prevent this, it is necessary to bring the spout adapter and the container body into close contact and form a seal between them. This required a great deal of force and impaired the handleability of the beverage container. In addition, even if the spout adapter and the container body are firmly pressed against each other, individual differences occur in the spout adapter due to manufacturing errors, etc., so a stable seal is formed between the spout adapter and the container body. It was difficult to do.

このようなことを考慮して、本実施の形態の飲料容器１は、飲み口アダプター３の個体差に依存することなく十分に安定したシールを形成しながら、飲み口アダプター３の容器本体２への取り付けに必要となる力を低減して、飲料容器１の取り扱い性を改善するための工夫がなされている。 In consideration of such a thing, the beverage container 1 of the present embodiment is attached to the container body 2 of the mouthpiece adapter 3 while forming a sufficiently stable seal without depending on the individual difference of the mouthpiece adapter 3. Ingenuity has been made to improve the handleability of the beverage container 1 by reducing the force required for mounting the beverage container 1.

具体的には、図３に示すように、板状部１０の第１面１１に、その周縁部に沿って環状凸部８が設けられている。この環状凸部８は、アダプター本体４が容器本体２に取り付けられた状態で、アダプター本体４に（より具体的には天壁部４ｂに）押し付けられる。 Specifically, as shown in FIG. 3, an annular convex portion 8 is provided on the first surface 11 of the plate-shaped portion 10 along the peripheral edge portion thereof. The annular convex portion 8 is pressed against the adapter main body 4 (more specifically, against the top wall portion 4b) with the adapter main body 4 attached to the container main body 2.

このような板状部１０の第１面１１に環状凸部８が形成された弾性部材５を用いた飲料容器１では、環状凸部８が設けられていない弾性部材を用いた飲料容器と比較して、飲み口アダプター３を容器本体２に取り付けるための力を低減させることができる。なぜなら、飲み口アダプター３を容器本体２に取り付ける際、アダプター本体４の天壁部４ｂと容器本体２の上端面２ａとの間で弾性部材５の板状部１０が圧縮されて弾性部材５と容器本体２の上端面２ａとの間にシールが形成されるが、板状部１０の第１面１１に環状凸部８が形成されている場合、環状凸部８が設けられていない場合と比較して、アダプター本体４の天壁部４ｂと容器本体２の上端面２ａとの間で圧縮される弾性部材５の体積を低減させることができるからである。 The beverage container 1 using the elastic member 5 having the annular convex portion 8 formed on the first surface 11 of the plate-shaped portion 10 is compared with the beverage container using the elastic member not provided with the annular convex portion 8. Therefore, the force for attaching the drinking spout adapter 3 to the container body 2 can be reduced. This is because when the spout adapter 3 is attached to the container body 2, the plate-shaped portion 10 of the elastic member 5 is compressed between the top wall portion 4b of the adapter body 4 and the upper end surface 2a of the container body 2 to form the elastic member 5. A seal is formed between the container body 2 and the upper end surface 2a, but when the annular convex portion 8 is formed on the first surface 11 of the plate-shaped portion 10, the case where the annular convex portion 8 is not provided and the case where the annular convex portion 8 is not provided. This is because the volume of the elastic member 5 compressed between the top wall portion 4b of the adapter main body 4 and the upper end surface 2a of the container main body 2 can be reduced in comparison.

また、板状部１０の第１面１１に環状凸部８を形成して、飲み口アダプター３を容器本体２に取り付ける際に弾性部材５の環状凸部８をアダプター本体４の天壁部４ｂに積極的に密着させることにより（すなわち、環状凸部８を板状部１０の他の部分に先行して天壁部４ｂに密着させることにより）、アダプター本体４や弾性部材５の個体差によって両者の密着性に違いが生じる虞を低減させることができる。したがって、飲み口アダプター３の個体差に依存することなく、アダプター本体４と弾性部材５との間に十分に安定してシールを形成することができる。 Further, an annular convex portion 8 is formed on the first surface 11 of the plate-shaped portion 10, and when the drinking spout adapter 3 is attached to the container main body 2, the annular convex portion 8 of the elastic member 5 is attached to the top wall portion 4b of the adapter main body 4. By positively adhering to (that is, by adhering the annular convex portion 8 to the top wall portion 4b prior to the other portion of the plate-shaped portion 10), due to individual differences in the adapter body 4 and the elastic member 5. It is possible to reduce the possibility that the adhesion between the two will be different. Therefore, it is possible to sufficiently stably form a seal between the adapter main body 4 and the elastic member 5 without depending on the individual difference of the drinking spout adapter 3.

図示された例では、図４から理解されるように、環状凸部８は、アダプター本体４の周壁部４ａと天壁部４ｂとの接続部４ｅとなる隅部に沿って配置される。これにより、環状凸部８の配置が安定し、安定したシールを形成することができる。 In the illustrated example, as will be understood from FIG. 4, the annular convex portion 8 is arranged along the corner portion serving as the connecting portion 4e between the peripheral wall portion 4a and the top wall portion 4b of the adapter main body 4. As a result, the arrangement of the annular convex portion 8 is stable, and a stable seal can be formed.

さらに、図示された例では、図４から理解されるように、環状凸部８の少なくとも一部は、容器本体２の環状の上端面２ａ上に位置している。また、アダプター本体４の天壁部４ｂから板状部１０に向かう方向（上下方向）に見て、環状凸部８の幅８ｗは、容器本体２の上端面２ａの幅２ｗよりも小さい。これにより、飲み口アダプター３を容器本体２に取り付ける際、アダプター本体４の天壁部４ｂと容器本体２の上端面２ａとの間で圧縮される弾性部材５の体積を、環状凸部８が設けられていない場合と比較して、効果的に低減させることができる。また、飲み口アダプター３を容器本体２に取り付ける際、環状凸部８をアダプター本体４の天壁部４ｂに積極的に密着させるということ（すなわち、環状凸部８を板状部１０の他の部分に先行して天壁部４ｂに密着させるということ）を、効果的に実現することができる。 Further, in the illustrated example, as can be seen from FIG. 4, at least a part of the annular convex portion 8 is located on the annular upper end surface 2a of the container body 2. Further, when viewed from the top wall portion 4b of the adapter main body 4 toward the plate-shaped portion 10 (vertical direction), the width 8w of the annular convex portion 8 is smaller than the width 2w of the upper end surface 2a of the container main body 2. As a result, when the spout adapter 3 is attached to the container body 2, the annular convex portion 8 measures the volume of the elastic member 5 that is compressed between the top wall portion 4b of the adapter body 4 and the upper end surface 2a of the container body 2. It can be effectively reduced as compared with the case where it is not provided. Further, when the spout adapter 3 is attached to the container main body 2, the annular convex portion 8 is positively brought into close contact with the top wall portion 4b of the adapter main body 4 (that is, the annular convex portion 8 is brought into close contact with the other plate-shaped portion 10). It is possible to effectively realize the fact that the portion is brought into close contact with the top wall portion 4b prior to the portion).

なお、図示された例では、環状凸部８は、板状部１０と一体的に形成されて、板状部１０の第１面１１から突出している。このように環状凸部８が板状部１０に支持されていることで、環状凸部８の捻れ等を防止することができ、また環状凸部８の配置を安定させることができる。したがって、環状凸部８とアダプター本体との間に安定したシールを形成することができる。 In the illustrated example, the annular convex portion 8 is integrally formed with the plate-shaped portion 10 and protrudes from the first surface 11 of the plate-shaped portion 10. Since the annular convex portion 8 is supported by the plate-shaped portion 10 in this way, twisting or the like of the annular convex portion 8 can be prevented, and the arrangement of the annular convex portion 8 can be stabilized. Therefore, a stable seal can be formed between the annular convex portion 8 and the adapter body.

また、容器本体２の環状の上端面２ａは、アダプター本体４の天壁部４ｂに正対する環状の第１上端面２ｂと、環状の第１上端面２ｂにその外側または内側から接続し、天壁部４ｂに対して傾斜した環状の第２上端面２ｃと、を有する。容器本体２の上端面２ａのうち環状の第１上端面２ｂは、飲み口アダプター３を容器本体２に取り付ける際、環状の第２上端面２ｃに先行して弾性部材５の板状部１０に接触し、板状部１０を圧縮して弾性部材５との間にシールを形成する。このことによっても、飲み口アダプター３を容器本体２に取り付けるための力を低減させることができる。なぜなら、容器本体２の環状の上端面２ａの全てが天壁部４ｂに正対する場合と比較して、アダプター本体４の天壁部４ｂと容器本体２の上端面２ａとの間で圧縮される弾性部材５の体積を低減させることができるからである。 Further, the annular upper end surface 2a of the container body 2 is connected to the annular first upper end surface 2b facing the top wall portion 4b of the adapter body 4 and the annular first upper end surface 2b from the outside or the inside, and is connected to the sky. It has an annular second upper end surface 2c that is inclined with respect to the wall portion 4b. Of the upper end surface 2a of the container body 2, the annular first upper end surface 2b is formed on the plate-shaped portion 10 of the elastic member 5 prior to the annular second upper end surface 2c when the drinking spout adapter 3 is attached to the container body 2. Upon contact, the plate-shaped portion 10 is compressed to form a seal with the elastic member 5. This also makes it possible to reduce the force for attaching the drinking spout adapter 3 to the container body 2. This is because, as compared with the case where all of the annular upper end surface 2a of the container body 2 faces the top wall portion 4b, the compression is performed between the top wall portion 4b of the adapter body 4 and the upper end surface 2a of the container body 2. This is because the volume of the elastic member 5 can be reduced.

図示された例では、第２上端面２ｃは、第１上端面２ｂにその外側から接続し、容器本体２が画成する開口面（環状端面によって囲まれる面）に対し、環状の上端面２ａの外側に向けて、容器本体２の上下方向における下側に傾斜している。これにより、天壁部４ｂと周壁部４ａとの接続部４ｅとなる隅部に向けて環状凸部８を押し付けることが可能となる。このことによっても、環状凸部８の配置を安定させることができ、環状凸部８とアダプター本体４との間に安定したシールを形成することができる。 In the illustrated example, the second upper end surface 2c is connected to the first upper end surface 2b from the outside thereof, and the annular upper end surface 2a is relative to the opening surface (the surface surrounded by the annular end surface) defined by the container body 2. The container body 2 is inclined downward in the vertical direction toward the outside of the container body 2. This makes it possible to press the annular convex portion 8 toward the corner portion that becomes the connecting portion 4e between the top wall portion 4b and the peripheral wall portion 4a. This also makes it possible to stabilize the arrangement of the annular convex portion 8 and form a stable seal between the annular convex portion 8 and the adapter main body 4.

また、図４によく示されているように、環状凸部８は、第１上端面２ｂの外側（すなわち、第２上端面２ｃの上側端縁２ｄの外側）に位置している。これにより、天壁部４ｂと周壁部４ａとの接続部４ｅとなる隅部に向けて環状凸部８を押し付けるということを、より効果的に実現することができる。したがって、環状凸部８の配置を効果的に安定させることができ、環状凸部８とアダプター本体４との間にさらに安定したシールを形成することができる。 Further, as is well shown in FIG. 4, the annular convex portion 8 is located outside the first upper end surface 2b (that is, outside the upper end edge 2d of the second upper end surface 2c). Thereby, it is possible to more effectively press the annular convex portion 8 toward the corner portion which is the connecting portion 4e between the top wall portion 4b and the peripheral wall portion 4a. Therefore, the arrangement of the annular convex portion 8 can be effectively stabilized, and a more stable seal can be formed between the annular convex portion 8 and the adapter main body 4.

The elastic member 5 has a first surface 11 that contacts the adapter body 4 to form a seal portion and a second surface that is provided facing the first surface 11 and contacts the end surface of the container body 2 to form a seal portion. 12 and. The first surface 11 is provided with an annular convex portion 8 that is pressed against the adapter body 4 when the adapter body 4 is attached to the container body 2.

このような飲料容器１によれば、飲み口アダプター３を容器本体２に取り付ける際に押し潰される弾性部材５の体積を低減させることができ、飲み口アダプター３を容器本体２に取り付けるための力を低減させることができる。また、飲み口アダプター３を容器本体２に取り付ける際に弾性部材５の環状凸部８をアダプター本体４に積極的に密着させることができるため、アダプター本体４や弾性部材５の個体差によって両者の密着性に違いが生じる虞を低減させることができる。したがって、飲み口アダプター３の個体差に依存することなく、アダプター本体４と弾性部材５との間に十分に安定してシールを形成することができる。以上により、上記飲料容器１によれば、飲み口アダプター３の個体差に依存することなく十分に安定してシールを形成しながら、飲み口アダプター３の容器本体２への取り付けに必要となる力を低減して、飲料容器１の取り扱い性を改善することができる。 According to such a beverage container 1, the volume of the elastic member 5 that is crushed when the drinking spout adapter 3 is attached to the container body 2 can be reduced, and the force for attaching the drinking spout adapter 3 to the container body 2 can be reduced. Can be reduced. Further, when the spout adapter 3 is attached to the container body 2, the annular convex portion 8 of the elastic member 5 can be positively brought into close contact with the adapter body 4, so that the two can be brought into close contact with each other due to individual differences between the adapter body 4 and the elastic member 5. It is possible to reduce the possibility of a difference in adhesion. Therefore, it is possible to sufficiently stably form a seal between the adapter main body 4 and the elastic member 5 without depending on the individual difference of the drinking spout adapter 3. As described above, according to the beverage container 1, the force required for attaching the drinking spout adapter 3 to the container body 2 while forming a seal sufficiently stably without depending on the individual difference of the drinking spout adapter 3. Can be reduced to improve the handleability of the beverage container 1.
