Problems solved by technology

[0007] In addition, there is a problem that when the straw container is opened and the vent is opened with the straw opening closed, and the vent is not closed again after the internal pressure is lowered, there will be a gap between the air and the contents. In the case of remaining inside the straw, when the cap is opened, the contents are displaced into the straw, and the contents originally remaining inside the straw fly out from the opening
[0012] Thus, in straw containers, parts such as straws, vents, and check valves are required to completely eliminate the splashing of the contents from the tip of the straw. Such parts are relatively small and easy to lose. In addition, they may be difficult to clean, or lead to increased costs, etc.

Embodiment 1

[0043] exist Figure 1~Figure 9Among them, reference numeral 1 denotes a portable beverage container according to the present invention as a whole, and the portable beverage container 1 is provided with: a metal vacuum-insulated container body 2; A plug body 4 made of synthetic resin, the base end side of a cup-shaped cover 7 is pivotally supported for rotation via a pair of left and right hinge shafts 6 arranged on the upper part of one end side of the rear side of the top 5 of the plug body 4 Thus, the cover 7 can be freely opened and closed, and the cover 7 can be held in a closed state by the hook-shaped locking portion 8 provided on the front side, which is the opposite side of the hinge shaft 6 . In addition, an operating portion 9 exposed to the front and urged outward by a spring 9A is integrally provided on the locking portion 8 , and a locking support portion 10 on which the locking portion 8 is locked is provided on the other end side of the cover 7 .

[0044] The ...

Embodiment 2

[0076] Next, other examples will be described. In addition, the same code|symbol is attached|subjected to the same part as said Example 1, and the detailed description is abbreviate|omitted.

[0077] exist Figure 10 In the illustrated embodiment 2, the locking member 32 is biased between the plate-shaped main body 35 and the upper surface 5U via the elastic member 50 so that it engages with the cover 7 when the cover 7 is closed, and locks when the cover 7 is released. never becomes closed. In the embodiment, the elastic member 50 is formed of a torsion spring, one end 50A of which is connected to the lock member 32 , the other end 50B is connected to the top 5 , and the middle part 50C is wound around both ends of the rotation center shaft 34 .

[0078] Furthermore, the elastic member 50 is used to apply force to the locking member 32 so that the locking member 32 engages with the cover 7 in the state of closing the cover 7, and when the closed state is released, it does n...

Embodiment 3

[0080] Such as Figure 11~Figure 13 As shown, in Embodiment 3, the locking member 32' is engaged with the main body 11 of the main body of the main body of the main body of the main body of the main body of the main body of the main body of the main body of the main body of the main body 11 in a substantially linear manner. Figure 12 As shown, by advancing the locking member 32 ′, the other side end recess 52 of the locking member 32 ′ is used to lock the one side end protrusion 51 of the cover 7 , and it is possible to utilize the downward direction from the locking member 32 ′. The lower end of the protrusion 53 is used to block the vent hole 31U. On the other hand, if Figure 13 As shown, by retracting the locking member 32 ′, the engagement between the protrusion 51 on one side of the cover 7 and the concave portion 52 on the other side end of the locking member 32 ′ is released; The lower end of the protrusion 53 moves to open the vent 31U. Furthermore, when the lock ...

Abstract

The invention discloses a plug of a beverage vessel. A structure is simplified and a cost is reduced by reducing the number of parts around a check valve. The pressure inside of the vessel body (2) is kept at the atmospheric pressure by the check valve (48) by operating a lock member (32) before opening a plug (7) even when the pressure inside of the vessel body (2) becomes negative by discharging the gas inside of the vessel body (2) accommodating hot water, warm tea or the like to once restore the pressure to the atmospheric pressure, resealing the vessel body, opening the plug and then sucking the beverage after opening the plug (7) to bring about the negative pressure of the inside of the vessel body. A protrusion (30) is provided at a closing member (15) closing an opening (3) of the vessel and made of an elastic material. The protrusion (30) is provided with a vent hole (31) in the up-down direction, an upper part having a large diameter to stop the downward omission of the protrusion (30), and the check valve (48) opening / closing the lower end of a suction hole and preventing the upward movement of the protrusion (30) at a position except a valve seat. The part number can be reduced as much as possible by integrating the vent hole 31, the check valve 48, and the like together with the closing member 15 into one part.

Description

technical field [0001] The present invention relates to a plug body for a beverage container. Background technique [0002] In the past, there is known a container for beverages, that is, as such a container for beverages, it has: a container main body that accommodates a liquid beverage; a base member that is assembled to the container main body and has a A straw hole through which a straw inserted into the container main body passes; and a lid body rotatably locked relative to a bearing portion provided at a position opposite to the straw hole of the base member. The upper part of the base member is opened and closed, the bearing part of the base member has a through hole, and the through hole is opened and closed by rotating the rod arranged on the bearing part, and the rod It is not provided in the vicinity of the straw hole, but is provided in the bearing portion having the through hole, so that the limited area of ​​the base member is not damaged for the rod, and the ...
