  In the prior art, in order to suspend the cold insulation container inside the bottle, the attachment is detachably fitted in the cylindrical part forming the opening of the bottle, and the cold insulation container is detachably attached to the lower part of the attachment. It is configured. Since the beverage container of patent document 1 is provided with a pull-top type spout tube that can be opened and closed, and is configured to pour the beverage from a small hole in the mouth tube, the beverage communication path required for the attachment is designed freely It is possible, there are no restrictions on its design, and no special ingenuity is required.

  However, a beverage container (hereinafter referred to as a “wide-mouth drinking type beverage container”) that drinks a beverage poured out from the wide-mouth opening by tilting the bottle by placing the user's lips against the opening edge of the wide-walled cylindrical section. In this case, when the beverage flows out from the spout formed in the attachment toward the opening edge of the cylindrical portion, the flow of the beverage is blocked by the attachment around the spout, and thus passes through the spout. There is a risk that the flux and flow rate of the beverage may fluctuate. In other words, if the flow rate or flow rate of the beverage toward the user's lips applied to the opening edge fluctuates, it becomes difficult for the user to drink the beverage smoothly, and the beverage may overflow or leak from the user's mouth, There is a problem of soiling clothes.

  In this regard, in order to make the outflow of the beverage blocked by the attachment smooth, it is necessary to provide a vent hole in the attachment and guide the outside air into the bottle. However, in this case, on the contrary, there is a problem that the beverage may flow out to the outside through the vent.

  For this reason, in order to provide a beverage container of a wide mouth drinking type in which a cold container is suspended, there is a problem to be solved with respect to the shape and structure of the attachment, particularly the configuration of the spout and the vent.

  Furthermore, the attachment / detachment structure of the attachment and the cold insulation container also has problems to be solved regarding ease of attachment / detachment work and stability in the attached state.

The present invention provides a beverage container that solves the above-mentioned problems, and as a means thereof, a bottle (4) provided with a cylindrical part (3) having an opening (2) in the upper part, An attachment (5) that is detachably fitted in the cylindrical part, a cold storage container (6) that is suspended by the attachment inside the bottle, and an opening part of the cylindrical part is detachably covered. In a beverage container composed of a cap (7) and configured to drink a beverage poured out from the opening by tilting the bottle with the user's lips in contact with the opening edge (2a) of the cylindrical portion,
The cylindrical portion (3) of the bottle forms an opening wall portion (8) at the inner peripheral edge of the opening portion (2), and a substantially horizontal step portion formed inward from the lower end of the opening wall portion. Extend the inner wall part (10) downward via (9),
The attachment (5) constitutes a dish-like body (15) having a bottom wall (13) and a peripheral wall (14), and a first diameter direction X1 which is the diameter direction of the dish-like body and is orthogonal to each other. Regarding the second diameter direction X2,
Forming fitting wall portions (16) and (16) which are located on both sides of the dish-like body (15) in the first diameter direction X1 and are fitted into the inner wall portion (10), and the fitting wall portion Forming a flange (17) to be placed on the step (9) at the upper end of
A pour-out wall portion (18) that is located on one side of the dish-like body (15) in the second diameter direction X2 and is separated from the inner wall portion (10) is formed, and located on the other side. And form a vent (19),
With the attachment (5) fitted in the cylindrical part (3), a spout (21) for pouring the beverage inside the bottle is provided between the inner wall part (10) and the pouring wall part (18). And forming a ventilation path (23) for introducing outside air into the bottle by a ventilation port (19) facing the extraction wall (18),
The cold container (6) includes a container flange (28) at the upper end of a neck (24) that forms an upper opening (25), and a plug (26) that is detachably inserted into the neck (24). A stopper flange (29) overlaid on the container flange (28) ,
The attachment (5) is provided with a holding rail (30) for detachably holding the superimposed upper and lower flanges (29) (28) ,
The holding rail (30) lies in a substantially U-shape extending from the introduction portions (31) (31) for receiving the upper and lower flanges (29) (28) along the circumferential direction of the flange. .

  In a preferred embodiment of the present invention, the pouring wall portion is formed so as to be inclined from the bottom wall of the dish-like body toward the pouring port, and the vent hole portion is formed so as to face the bottom wall. .

  The beverage container 1 of the present invention inserts the cold insulation container 6 into the bottle 4 in a state where the cold storage container 6 stored by the cold storage means C is attached to the attachment 5 after the beverage D is accommodated in the bottle 4. In the state where the attachment 5 is fitted in the cylindrical portion 3 and the cold container 6 is suspended inside the bottle 4 in this manner, the cylindrical portion 3 is covered with the cap 7 so that the beverage can be used for a long time. D can be kept cool.

  Therefore, when the user drinks the beverage D, the cap 7 is removed, and the position of the spout 21 is confirmed by visually recognizing from the opening 2 of the tubular portion 3, and then the spout 21 is set as the lower side. The beverage flowing out from the spout 21 can be drunk by placing the lips on the opening edge 2a facing the nozzle 21 and tilting the bottle 4.

  When the bottle 4 is tilted, the beverages D inside flow together toward the attachment 5 and are received by the bottom wall 13 of the attachment 5. At this time, since the spout 21 toward the user's lips is positioned on the lower side and the vent portion 19 that forms the vent path 23 is positioned on the upper side, there is no possibility that the beverage D flows out of the vent path 23. Moreover, since the surrounding walls 14 and 14 located in the both sides of the spout 21 are fitted by the inner wall part 10 of the cylindrical part 3, the drink D does not flow out outside from this part.

  During drinking, since the outside air is guided into the bottle 4 through the air passage 23, the beverage D is smoothly poured out from the narrow spout 21 without changing the flux and the flow velocity. Therefore, the beverage D does not overflow or leak from the user's mouth and is poured out so that it can be easily drunk.

Since the spout 21 is configured to be formed between the tubular portion 3 and the spout wall 18, there is no need to separately provide a spout member having a complicated shape or structure, and the attachment 5 is simplified. The desired effect can be realized simply by configuring.
According to the present invention, the container flange 28 and the plug flange 29 that are overlapped with each other in a state where the plug 26 is attached to the cold insulation container 6 are attached to the holding rail 30 that extends in a U shape from the introduction portions 31 and 31. Since the upper and lower flanges 28 and 29 are sandwiched by the holding rail 30, the mounting and fixing state of the cold insulation container 6 with respect to the attachment 5 is stable, and the stopper 26 and the cold insulation container 6 are inside the bottle 4. Are not separated from each other, and there is no possibility of causing an accident that the cold storage means C is mixed into the beverage D.

Further, according to the present invention described in claim 2, Note Dekabe portion 18 is formed so as to be inclined toward the bottom wall 13 of the dish-shaped body 15 to the spout 21, spout 21 It is gradually narrowed toward the opening edge 2a on the outlet side, and thereby, the flux and flow rate of the beverage D to be dispensed are controlled so as to be easy to drink.

  For example, when the bottle 4 is tilted excessively at the start of drinking, the beverages D inside the bottle 4 flow toward the spout 21 all at once. In addition, when an unexpected impact or vibration is applied to the bottle 4 during drinking, the beverage D fluctuates inside the bottle 4 and a large amount of the beverage D tends to flow toward the spout 21. In such a case, the spout 21 is constricted in the spout direction by the sloping spout wall 18, and the flow and flow rate of the sprinkled beverage D are controlled to be constant, thereby facilitating drinking. To do.

  Further, since the vent portion 19 is formed so as to face the bottom wall 13 of the dish-like body 15, the beverage portion D that fluctuates in a wave shape as described above jumps inside the bottle 4, and thereby the vent portion 19. Even if the beverage D overflows, the overflowed beverage D is caused to flow down to the pouring wall portion 18 along the bottom wall 13 of the dish-like body 15 and converge toward the pouring port 21 from the pouring wall portion 18. Therefore, it does not overflow or leak from the user's mouth.
