However, in a beverage container having a container body and a spout adaptor detachably attached to the container body, when the spout adaptor is attached to the container body, in order to prevent beverage from passing from the spout adaptor to the container body If there is leakage between the two, the spout adapter needs to be brought into close contact with the container body to form a seal between the two. This requires a lot of force and can impair the handling of the beverage container. In addition, even if the spout adapter and the container body are firmly crimped to each other, there are individual differences in the spout adapter due to manufacturing errors and the like, so it is difficult to stably form a seal between the spout adapter and the container body.

Taking this situation into consideration, the beverage container 1 of the present embodiment has studied to form a sufficiently stable seal without depending on individual differences in the spout adapter 3 (ie, even if there are individual differences in the spout adaptor 3), and to reduce the spout The force required to attach the adaptor 3 to the container body 2 improves the operability of the beverage container 1 .

Specifically, as shown in FIG. 3 , the annular convex portion 8 is provided on the first surface 11 of the plate-shaped portion 10 along the peripheral portion thereof. The annular convex portion 8 is pressed against the adapter main body 4 (more specifically, the top wall portion 4 b ) in a state where the adapter main body 4 is attached to the container main body 2 .

In the beverage container 1 using the elastic member 5 in which the annular convex portion 8 is formed on the first surface 11 of the plate-like portion 10, compared with the beverage container using the elastic member without the annular convex portion 8, the The force for attaching the spout adapter 3 to the container body 2 is reduced. This is because, when the spout adapter 3 is attached to the container body 2, the plate-like 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. A seal is formed between the elastic member 5 and the upper end surface 2 a of the container body 2 , but when the annular convex portion 8 is formed on the first surface 11 of the plate-shaped portion 10 , it is the same as the case where the annular convex portion 8 is not provided. By contrast, the volume of the elastic member 5 compressed between the top wall portion 4b of the adapter body 4 and the upper end surface 2a of the container body 2 can be reduced.

In addition, by forming the annular convex portion 8 on the first surface 11 of the plate-like portion 10, the annular convex portion 8 of the elastic member 5 is positively brought into close contact with the joint when the spout adapter 3 is attached to the container body 2. 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 top wall portion 4b earlier than the other parts of the plate-like portion 10 ), so that it is possible to reduce the number of parts of the adapter main body 4 and the elastic member 5 caused by differences in the close contact between the two. Therefore, it is possible to form a seal between the adaptor main body 4 and the elastic member 5 sufficiently stably without depending on the individual differences of the spout adaptor 3 (without being influenced by the individual differences of the spout adaptor 3 ).

In the example of the drawing, as can be understood from FIG. 4 , the annular convex portion 8 is arranged along the corner portion serving as the connection portion 4e of the peripheral wall portion 4a of the adapter body 4 and the top wall portion 4b. Thereby, the arrangement of the annular convex portion 8 can be stabilized, and a stable seal can be formed.

In addition, the width 8w of the annular convex portion 8 is smaller than the width 2w of the upper end surface 2a of the container body 2 when viewed from the top wall portion 4b of the adapter body 4 toward the plate-like portion 10 (vertical direction). As a result, when the spout adapter 3 is attached to the container body 2, compared with the case where the annular convex portion 8 is not provided, the upper end surface of the top wall portion 4b of the adapter body 4 and the container body 2 can be effectively lowered. The volume of the compressed elastic member 5 between 2a. In addition, when the spout adaptor 3 is attached to the container body 2, the annular convex portion 8 can be effectively brought into close contact with the top wall portion 4b of the adaptor body 4 (that is, the annular convex portion 8 is made to be in close contact with the top wall portion 4b of the adaptor body 4 (that is, the annular convex portion 8 is made smaller than the plate). The other parts of the shaped portion 10 are in close contact with the top wall portion 4b earlier).

In addition, in the example of a figure, the annular convex part 8 is formed integrally with the plate-shaped part 10, and protrudes from the 1st surface 11 of the plate-shaped part 10. By supporting the annular convex portion 8 by the plate-like portion 10 in this way, twisting of the annular convex portion 8 and the like 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.

In addition, the annular upper end surface 2a of the container body 2 has an annular first upper end surface 2b facing the top wall portion 4b of the adapter body 4, and is connected to the annular first upper end surface 2b from the outside or inside of the annular first upper end surface 2b. And the annular 2nd upper end surface 2c inclined with respect to the top wall part 4b. When the spout adapter 3 is attached to the container body 2, the annular first upper end surface 2b of the upper end surface 2a of the container body 2 is placed in contact with the plate-shaped portion of the elastic member 5 before the annular second upper end surface 2c. 10 contacts, and the plate-shaped portion 10 is compressed to form a seal between the adapter body 4 and the elastic member 5 . Thereby, the force for attaching the spout adapter 3 to the container body 2 can also be reduced. This is because the difference between the top wall portion 4b of the adapter body 4 and the upper end surface 2a of the container body 2 can be reduced compared to the case where the entire annular upper end surface 2a of the container body 2 faces the ceiling wall portion 4b. The volume of the elastic member 5 that is compressed between.

In the example shown in the figure, the second upper end surface 2c is connected to the first upper end surface 2b from the outside, and faces the annular upper end surface with respect to the opening surface (surface surrounded by the annular end surface) defined by the container body 2 The outer side of 2a is inclined toward the lower side of the container body 2 in the vertical direction. Thereby, the annular convex part 8 can be pressed toward the corner part which is the connection part 4e of the top wall part 4b and the peripheral wall part 4a. Thereby, the arrangement of the annular convex portion 8 can also be stabilized, and a stable seal can be formed between the annular convex portion 8 and the adapter body 4 .

Moreover, as shown in FIG. 4, the annular convex part 8 is located in the outer side of the 1st upper end surface 2b (namely, the outer side of the upper side edge 2d of the 2nd upper end surface 2c). Thereby, the annular convex part 8 can be pressed toward the corner part which is the connection part 4e of the top wall part 4b and the peripheral wall part 4a more effectively. 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 body 4 .
