Beverage for beverage containers

The invention relates to a plug body for a beverage container, in particular to a water injection port/drinking mouth covered with a cover body, the cover body being pivotally connected with the plug body and capable of opening the cover body in a closed state by pressing. Plug body.

Traditionally, some beverage containers have a sliding bar extending on one side of the lid. When using the container for such a beverage, the user only has to hold the handle of the container body with one hand and press it from one side. The drinker body is tilted while the lid is extended, so that the contents of the beverage container body can be poured out. However, in the beverage container designed with such a structure, when the content liquid is a hot drink, the pressure in the container may rise, so that the water stop valve body cannot be opened, and the above-mentioned beverage container is often used, and the content liquid often occurs. Can't be dumped and other issues. In order to solve such problems, the manufacturer designs a plug for a beverage container. When the user uses the beverage container and wants to perform the operation of pouring the liquid, the water stop valve body first vents the valve body and tries to decompress the valve, and then triggers the cover body. In this case, even if a liquid such as hot water or hot drinks is to be placed in the beverage container, it can be smoothly injected into the container for a beverage, and the structure is as described in Japanese Laid-Open Patent Publication No. 2004-315009 (Patent Document 1). Show. However, in this type of beverage container, when the user operates the beverage container so that the contents of the beverage container are poured out, if the slider is not continuously pressed, the content liquid cannot be poured out to the outside. Therefore, if the user is a child or an elderly person with less strength, it is often difficult to complete the operation by himself.

In addition, a plug body of another type of beverage container can be used to lock the lid body of the plug body through the locking member and open the cover through the annular elastic member on the hinge shaft. The structure is as disclosed in Japanese Patent No. 4736133 (Patent Document 2). Shown. However, in the case of using such a beverage container, it is necessary to remove the plug body, the water stop valve body and the cover during cleaning, which is quite time consuming, and if the operation is inadvertently removed, it is difficult to clean it so that it is subsequently It is worrying about the use of hygiene. In addition, push through Due to the long-term use, the spring of the gas valve body may cause problems such as elastic deterioration and incomplete function due to fatigue of the metal, and it is difficult to visually judge whether the plug body is in an open or closed state.

In another type of body of the beverage container, when the button is released and released, the rotation of the body of the body is temporarily stopped, and the beverage attached to the lid is not easily scattered. The structure is as disclosed in Japanese Laid-Open 2010- Japanese Patent Publication No. 126163 (Patent Document 3). In the beverage container of this type, the opening of the lid of the lid is large, and the cleaning flow of the liquid flow path is good. Even if the inside of the container is pressurized, the opening of the lid of the lid can be temporarily stopped when the plug is opened, and the lid can be prevented from being borrowed. This is turned on, but in the decompressed state, the lid cannot be opened by a single action, and thus it is easy to cause inconvenience in operation.

Another type of body of the beverage container, if the lid is not opened under the decompression state when the button is released, the finger can be easily opened by placing the finger on the protrusion at the front of the lid. The structure is as follows: Japanese Patent Application Publication No. 2011-218148 (Patent Document 4). In this type of beverage container, although the front of the lid is provided with a protrusion, it is convenient to open the plug body with a finger, and the lid of the lid is simple to open. However, the process of decompressing and opening the lid of the lid requires separately operating the button to release the button. And the two actions of opening the lid with a finger, the operation is slightly complicated and not very convenient.

Therefore, the problem to be solved by the present invention is to design a plug body for a beverage container, so that any person can surely perform the opening/closing operation through one action.

In view of the structural design of the plug body of the existing beverage container, there are many problems. Therefore, after long-term efforts and experiments, the inventors finally developed and designed a plug body for a beverage container of the present invention, with the aim of using the present invention. Effectively solve the above problems.

A first object of the present invention is to provide a plug body for a beverage container, comprising a plug body, a water inlet/drinking port, a lid body, a water stopping member, a locking member and a locking releasing member. The plug main system is detachably disposed in an upper opening portion of a beverage container body, a liquid flow path is formed in the plug body, and the plug body is provided with a liquid through hole and a vent hole. And a venting valve, wherein the liquid through hole can discharge the content liquid in the beverage container body, the vent hole can discharge the air in the container body, and the vent valve is disposed on the vent hole; the water inlet/drinking port And disposed at the front end of the plug body; the cover body is provided with a pivot shaft, and the pivot shaft is pivotally connected to the rear end of the plug body to enable the cover body to be opposite to the plug The body body is free to rotate, thereby opening or closing the liquid flow path; The water stopping member is disposed on the cover body, and can liquid-tighten the liquid flow path from above; the locking member can lock the cover body to make the cover body into a closed state, and the cover body is brought to the card When the locking release member is pressed downward, the vent valve is first opened to allow the internal pressure of the beverage container body to be released through the vent hole, and the locking releasing member can release the card. The locking of the stopper causes the lid to be opened and can be pushed upward. In this way, the user can perform the opening/closing operation only by pressing the locking releasing member, and the operation is relatively simple, and in the process of opening the cover, when the locking releasing member is pressed, the cover body is When the locking member is locked to the main body of the plug, the internal pressure can be released.

According to a second object of the present invention, the lock releasing member presses the vent valve through a water stop member. In this way, when the pressure is released, the user does not have to worry that the water droplets of the content liquid will drip down to the inside of the lid, and can be kept clean.

According to a third object of the present invention, the vent valve is elastically deformed when the pressure is reduced in the container body for the beverage. In this way, the water stop portion of the vent valve can be used as a check valve, and the decompressed state can be automatically released when the pressure is reduced.

According to a fourth aspect of the present invention, the locking releasing member transmits a portion of the venting valve through the damper, so that the internal pressure of the container body for the beverage can be released through the vent hole. In this way, the damper valve can be deformed by the locking release member, and the internal pressure can be released. When decompressing, the decompression state is automatically released by the deformation of the valve body.

According to a fifth object of the present invention, the vent valve is provided with a plurality of water stopping portions. In this way, the water repellency can be further improved.

According to a sixth aspect of the present invention, an annular elastic member is disposed on the cover body adjacent to the hinge shaft, and the locking member is urged in the locking direction by the elastic force of the annular elastic member. In this way, the elastic member can be used to simultaneously advance the cover body in the opening direction and advance in the locking direction of the locking member, thereby effectively reducing the number of components to be used, thereby saving internal assembly space. And can effectively reduce manufacturing costs.
