And a packing 14 in contact with the neck portion 13. The lid portion 10 is formed of a celestial cylindrical body, and includes a disk-shaped upper portion 15 and a cylindrical wall portion 16 that hangs down from the periphery of the upper portion. The inner plug portion 9 is fixed to the inner surface of the upper portion 15 of the lid portion 10 at the top portion 9a. In the figure, 9b is a heat insulating material built in the inner plug portion 9.

  The beverage container 1 can carry the beverage accommodated in the container body 3 without leaking outside by closing the opening 2 with the stopper 4 and removing the stopper 4 to open the opening. It is comprised so that a drink can be drunk directly from 2.

  Next, the drinking mouth 5 which is a characteristic configuration of the present invention will be described in detail. As shown in FIG. 2, the drinking mouth 5 includes a mouth body 20 formed in a cylindrical shape. The mouth portion main body 20 is made of a rubber-like elastic material, for example, silicon rubber, and is formed so as to be fitted to the opening portion 2 from the outside. In addition, the mouth part main body 20 includes a step part 21 formed in a circular shape on the outer peripheral surface and a drinking mouth part 22. The step portion 21 is formed by protruding an outer peripheral surface located substantially in the center in the axial direction of the mouth portion main body 20 outward in the radial direction. The drinking mouth portion 22 is a portion closer to the distal end 20a than the stepped portion 21, and is formed smaller in diameter than the outer diameter of the mouth portion main body 20 on the proximal end 20b side. Further, the drinking mouth part 22 has a flexible part 23 in which the tip 20a of the mouth part body 20 is projected. Further, on the outer peripheral surface of the mouth body 20 and on the base end 20 b side from the step portion 21, a grip portion 24 having an outer diameter substantially the same as the outer diameter of the container body 3 is formed in a state of being attached to the opening 2. Has been.

  As shown in FIG. 3, the mouth portion main body 20 has a locking portion 25 and a locking portion 26 formed on the inner peripheral surface. The locking portion 25 is formed so as to be locked to a locking receiving portion 17 provided on the outer peripheral surface of the opening 2. The locking portion 25 is formed on the proximal end 20b side of the mouth portion main body 20 with respect to the stepped portion 21, and is formed by protruding the inner peripheral surface inward in the radial direction. That is, the locking part 25 is formed inside the grip part 24 formed on the outer peripheral surface of the mouth part body 20. The stopper 26 is formed so as to cover the tip 2 a of the opening 2 when the mouth body 20 is attached to the opening 2. In the present embodiment, the stop portion 26 is formed so as to protrude stepwise inward in the radial direction.

  Next, the operation and effect of the beverage container 1 configured as described above will be described. The drinking mouth 5 is attached to the outside of the opening 2 by extending the mouth body 20 outward in the radial direction (FIG. 4). Here, the drinking mouth 5 is configured such that the mouth body 20 is made of an elastic material, and is further configured to be locked with the locking receiving portion 17 of the opening 2 at the locking portion 25. It can be easily and reliably attached to and detached from the opening 2 and can be prevented from coming off due to accidental falls.

  Further, in the drinking mouth 5, the entire lower surface of the stopper 26 is fitted to the outer peripheral surface of the opening 2 on the inner peripheral surface of the mouth body 20. Accordingly, the drinking mouth 5 is more rigid because the inner peripheral surface of the mouth portion main body 20 and the outer peripheral surface of the opening portion 2 are in contact with each other except for the flexible portion 23 protruding from the tip 2a of the opening portion 2. The container body 3 can be fitted. Accordingly, the drinking mouth 5 can prevent the drinking mouth 5 from coming off or the container body 3 from falling out of the drinking mouth 5 even when the container body 3 is turned over or only the mouth body 20 is held. Thus, it is possible to more reliably prevent the beverage from leaking and improve the user-friendliness.

  Here, since the user can easily hold the container body 3 by forming the grip part 24 on the outer peripheral surface of the mouth part body 20, the drinking mouth 5 can improve the user's convenience. it can. Furthermore, the drinking mouth 5 is configured such that the locking portion 25 is disposed inside the grip portion 24, so that when the user grips the grip portion 24, the locking portion 25 is pressed against the locking receiving portion 17. Therefore, the coupling between the drinking mouth 5 and the container body 3 becomes stronger. Accordingly, it is possible to more reliably prevent the container body 3 from falling out of the drinking mouth 5 when being carried.

  When the drinking mouth 5 is attached to the opening 2 as described above, the user grips the grip portion 24, directly attaches the mouth to the drinking mouth 5, and tilts the container main body 3. Beverages pre-stored inside can be drunk. At this time, the beverage passes through the neck portion 13 and passes through the female screw 11, the flexible portion 23, and the drinking mouth portion 22. Here, the region from the neck 13 to the mouthpiece 22 is referred to as a beverage passage region A.

  Here, the drinking mouth 5 can prevent the front-end | tip 2a of the opening part 2 from touching a user's mouth in a normal use condition by coat | covering the front-end | tip 2a of the opening part 2 with the stop part 26. FIG. Furthermore, since the drinking mouth 5 is provided with the flexible part 23 at the tip 20a of the mouth body 20, the fit between the user's mouth and the drinking mouth 5 can be achieved by deforming the tip of the drinking mouth 5 according to the user's mouth. Since a feeling increases, a user's usability can be improved more.

As shown in the figure, a slight gap B is formed between the stopper 26 and the tip 2a of the opening 2 in design. Since the gap B can absorb an error in manufacturing the container main body 3, productivity can be improved.

  Moreover, when carrying, the plug body 4 is attached to the opening 2 with the drinking mouth 5 attached. The plug 4 stops when the male screw 12 enters the opening 2 while being screwed into the female screw 11, and the packing 14 comes into contact with the neck 13 and the inner seal portion 30 is formed. Thereby, as for the container 1 for drinks, the opening part 2 is obstruct | occluded and it prevents that the drink accommodated in the container main body 3 leaks outside.

  At the same time, the lid portion 10 of the plug body 4 has the lower end 16a of the wall portion 16 in contact with the step portion 21 of the drinking mouth 5 to form a first outer seal portion 31 (FIG. 5). Thereby, the drinking mouth 5 can prevent more reliably that the residual water adhering to the drink passage area | region A leaks outside.

  Here, the drinking mouth 5 includes the mouth portion body 20 made of an elastic material, and the step portion 21 is formed integrally with the mouth portion body 20, so that it is not necessary to attach a packing as a separate member as in the prior art. Therefore, the number of parts can be reduced by that amount, and as a result, the product cost can be reduced. Moreover, since the drinking mouth 5 can reduce the trouble at the time of removing or attaching for cleaning by reducing the number of parts, and also reducing the risk of losing parts, User convenience can be improved.

  Further, when the stopper 4 is tightened, the drinking mouth 5 is deformed by the step portion 21 so that the flexible portion 23 comes into contact with the top portion 9a as the inner surface of the lid portion 10, and the inner seal portion 30 A second outer seal portion 32 can be formed between the first outer seal portion 31 and the first outer seal portion 31 (FIG. 6). Thereby, the sealing performance in the drink passage area A can be improved.

  In addition, since the stopper 26 is brought into contact with the tip 2a of the opening 2 with a strong force due to the deformation of the flexible portion 23, the beverage is placed between the inner peripheral surface of the mouth body 20 and the outer peripheral surface of the opening 2. Intrusion can be prevented more reliably. Accordingly, the drinking mouth 5 can more reliably prevent the beverage from leaking from the gap between the mouth portion main body 20 and the opening portion 2, and thus the user convenience can be improved.

  In addition, since the mouthpiece body 20 is formed of an elastic material, the drinking mouth 5 can be cleaned by squeezing or cleaning the inner peripheral surface by turning over the surface when it is removed from the container body 3 for cleaning. It can be improved and used hygienically.

  The present invention is not limited to the above-described embodiment, and can be appropriately changed within the scope of the gist of the present invention. For example, in the above-described embodiment, the case where the container body 3 includes the outer container 6 and the inner container 7 and a heat insulating layer 8 such as a vacuum is formed between the outer container 6 and the inner container 7 will be described. However, the present invention is not limited to this, and may be applied to a resin or metal container that does not have heat insulation, as long as it is possible to drink a beverage by directly opening the opening of the container body.
