Description

  The present invention relates to a portable portable beverage container for storing various beverages such as water and tea.

  There are roughly two types of such portable beverage containers. One is a cup with a drink inside and a lid that can be used as a cup. The container is tilted to pour the drink into the cup or lid before drinking. The other is a direct drinking type with a mouth directly attached to one drinking mouth formed at the upper end of the container.

  In the former container, since the liquid is poured out and then drinks indirectly, there is no resistance compared to drinking a drink in one container by a plurality of people when going out for a picnic or hiking. For this reason, there existed an advantage by sharing a drink.

  However, in the latter container, the only drinking mouth is a direct mouth to drink, so there is a great resistance to drinking by multiple people. For this reason, it was inconvenient, such as being unable to respond when someone forgot to drink or drank it because of a picnic or hiking.

  Conventionally, there has been proposed one that can select a pouring type or a direct drinking type (see Patent Document 1). However, although this helps to eliminate the inconveniences as described above, there is a problem that the number of parts is large and there are many procedures for drinking. In other words, it diminished the benefits of direct drinking.

  The portable beverage container 11 in the present embodiment is configured as described above. Hereinafter, a beverage in which two users A and B who use the portable beverage container 11 are stored in the liquid storage container 12 ( Actions and effects when drinking (not shown) will be described.

First, one user A removes from the main body member 16 by releasing the screwing of the female screw portion 14a and the male screw portion 19a while rotating the lid 14 with respect to the main body member 16 (liquid storage container 12). .
Then, the user A confirms that the drinking mouth member 17 is positioned so that the drinking mouth portion 29a used by the user A coincides with the mark 19c in the circumferential direction. Thus, if the spout member 17 is positioned, the lever 26 is raised.

  As a result, the channel 21 is opened, and the lower end opening 28c of the drinking channel 28a and the channel opening 21a communicate with each other, so that the user A can open the mouth of the liquid storage container 12 to the drinking unit 29a. You can drink beverages.

  In this way, even when the liquid storage container 12 is tilted, there is no possibility that the beverage will flow out from the other drinking channel 28b that does not have a mouth.

Next, a procedure for the user B to drink a beverage using his / her mouth part 29b will be described.
As shown in FIG. 5 (a), the user B takes a drink in order to change from the position where the drinking part 29a is positioned to the own drinking part 29b at a position facing the mark 19c. The mouth member 17 is rotated with respect to the main body member 16.

  Specifically, the user B squeezes the outer periphery of the spout member 17 with a finger and rotates the spout member 17 clockwise, for example. Thereby, engagement with the positioning recessed part 31a of the main body member 16 and the positioning convex part 31b of the drinking mouth member 17 can be cancelled | released. As described above, once the engagement between the positioning recess 31a and the positioning protrusion 31b is released, the mouthpiece member 17 can be smoothly rotated as shown in FIG. 5B.

  The form of the upper part of the cross-section of the main part of the inner plug 13 when the spout member 17 is rotated with respect to the main body member 16 is as shown in FIG. That is, since neither of the lower end openings 28c, 28d of the drinking passage 28a (28b) is in communication with the passage opening 21a, even if the drinking member 17 is being rotated, Even if the container 11 is inclined, the beverage in the liquid storage container 12 does not flow out.

  Then, when the user B rotates the spout member 17 until the spout portion 29b reaches the vicinity of the mark 19c, the position of the positioning recess 31a in the circumferential direction of the main body member 16 is set to the positioning protrusion of the spout member 17. The mouthpiece member 17 is gently rotated with a force that allows the portion 31b to pass lightly.

  As a result, as shown in FIG. 7, the positioning protrusion 31b is engaged with the positioning recess 31a, so that the drinking mouth member 17 is rotated in a state where the drinking mouth member 17 and the body member 16 are accurately positioned. Can be stopped.

Therefore, the user B's drinking channel 28b is in communication with the channel opening 21a, so that the user B can drink the beverage by tilting the portable beverage container 11.
In addition, after finishing drinking, the lever 26 may be laid down and the lid 14 may be left.

  As described above, since the inner plug 13 has a plurality of drinking passages 28a and 28b serving as drinking openings, there is no resistance between the user A and the user B and one portable beverage container 11 is provided. Can be shared.

  Moreover, the drinking mouth can be easily changed by simply rotating the drinking mouth member 17 with respect to the main body member 16.

  Next, the portable beverage container 11 according to another embodiment will be described.

The flow path opening 21a is not limited to the structure provided on the upper bottom surface 18b of the main body member 16 (the trunk member 18), and a plurality of flow path openings 21a may be provided.
For example, there are two flows on the upper bottom surface 18b of the main body member 16 (the trunk member 18): a channel opening having the same diameter as the drinking channel 28a, 28b and a channel opening having a smaller diameter than the drinking channel. A road opening can be provided.

  In the case of adopting the above configuration, a flow path opening communicating with the drinking passages 28a and 28b is arbitrarily selected according to whether the user is an adult or a child, or according to the remaining amount of beverage in the liquid storage container 12. You can select and adjust the beverage spillage.

  Moreover, about the portable beverage container 11 which concerns on other embodiment, the sealing member 10 for the water stop inserted in the said drinking mouth member 17 and the main-body member 16 is not restricted to the form mentioned above, an attachment form, for example, a flow path A sealing member that can be attached to the periphery of the opening 21a and / or the periphery of the lower end openings 28c and 28d of the drinking passages 28a and 28b may be attached to stop the water.

  Further, for example, when the lid 14 is attached to the main body member 16, the lever 26 collapses in conjunction with the operation thereof to open the flow path 21, or conversely to the main body member 16. When the lid 14 is removed, the lever 26 rises in conjunction with the operation, and the flow path 21 may be closed.

  In addition, the portable beverage container 11 may be configured without the lid 14 or the plug member 23, for example. In this configuration, when the flow path 21 is closed, for example, the above-described spout member with respect to the main body member 16 so that the flow path opening 21 a and the lower end openings 28 c and 28 d of the spout passage 28 do not communicate with each other. Even if the portable beverage container 11 is tilted while the 17 is rotated, it is possible to sufficiently prevent the beverage from flowing out of the liquid storage container 12.

  In the correspondence between the above-described embodiment and the configuration of the present invention, the drinking mouth portions 29a and 29b of this embodiment correspond to the drinking mouth of the present invention, but the present invention is limited only to the configuration of the above-described embodiment. In fact, many embodiments can be obtained.
