Description

Technical Field

[0001] The present invention relates to the technical field of beverage containers, and in particular to a beverage container plug. Background Art

[0002] A straw cup is a water cup that allows you to drink from the drink in the cup through the drinking spout on the lid. It has good sealing properties, is not easy to leak, and is easy and portable to drink from. It can be used as a special water cup for infants and children. However, when a drink above room temperature is placed in the cup, a positive pressure state will be formed inside the cup. At this time, when the button is pressed to open the lid, the positive pressure inside the cup will cause the drink to splash out from the drinking spout, creating the risk of staining or wetting clothes or even scalding.

[0003] In order to solve the problem of water spraying from the drinking spout when the lid is opened, there are mainly two types of stopper structures on the market: the first is to add a thin-walled valve sheet with a straight or cross cut on the outer mouth or inner bottom of the drinking spout, and use the opening and closing force of the valve sheet to resist the internal pressure, thereby suppressing the problem of beverage splashing at the drinking spout straw; the second is to set an air intake mechanism and an exhaust mechanism on the stopper body, and operate the exhaust mechanism to release the air pressure in the cup before opening the upper lid to open the drinking spout straw, thereby solving the problem of beverage splashing at the drinking spout straw, such as the beverage container mentioned in patent 201410412779.8.

[0004] However, for the first prior art, although the valve plate structure on the straw can suppress the problem of beverage splashing at the drinking mouth to a certain extent, when the internal pressure reaches a certain level, the liquid can still break through the closing force of the valve plate and splash out from the drinking mouth tube. On the other hand, for the second prior art, although it can effectively prevent the problem of water spraying, it has the following disadvantages: the exhaust hole and the air inlet hole are independent of each other, the plug body structure is complex, and it is inconvenient to clean; the exhaust hole seal needs to be fully inserted into the exhaust hole, which is difficult to assemble, and water leakage will occur when it is not assembled in place; because the exhaust hole must be sealed with the lower end of the button, the design freedom of the exhaust hole position and the button shape is limited.

Preferably, the wall part 21 vertically extends downward from the lower surface of the cover body 2, and the lower end of the wall part 21 can be operably pressed against the drinking mouth part 3.

[0053] Further, as a preferred embodiment, the mouthpiece component 3 is formed of an elastic material, and the elasticity of the mouthpiece component 3 applies force to the cover body 2 in the opening direction.

[0054] Furthermore, as a preferred embodiment, a locking mechanism is also provided which can be operated to keep the cover 2 in a closed state, a partially opened state or a fully opened state.

[0055] Further, as a preferred embodiment, the locking mechanism includes: a first locking piece 41 , and the first locking piece 41 is arranged on the cover body 2 facing outward.

[0056] Further, as a preferred embodiment, the locking mechanism includes: a button component 40, which is installed by the button hinge axis to be able to swing freely, and has a first locking portion 42 at the upper part that is engaged with the first locking piece 41; wherein the first locking piece 41 and the first locking portion 42 cooperate to keep the cover body 2 in a closed state.

[0057] Specifically, see Figure 1 As shown, the upper surface of the first engaging piece 41 contacts with the lower surface of the first engaging portion 42 to form an engagement. Preferably, the upper surface of the first engaging piece 41 and the lower surface of the first engaging portion 42 are both substantially horizontal.

[0058] Further, as a preferred embodiment, the locking mechanism includes: a force applying mechanism 43, which applies force to the button component 40 in the engagement direction with the first engagement piece 41. The force applying mechanism 43 preferably uses an elastic component to achieve the above force application, and the force applying mechanism 43 can be a spring or silicone with a certain elasticity.

[0059] Further, as a preferred embodiment, the locking mechanism includes: a second locking piece 44, and the second locking piece 44 is arranged on the cover body 2 facing inward.

[0060] Further, as a preferred embodiment, the upper portion of the button component 40 also has a second engaging portion 45 engaged with the second engaging piece 44; wherein the second engaging piece 44 and the second engaging portion 45 cooperate to place the cover body 2 in a partially open state.

[0061] Specifically, see Figure 1 As shown, the upper surface of the second engaging piece 44 contacts the lower surface of the second engaging portion 45 to form an engagement. Preferably, the upper surface of the second engaging piece 44 and the lower surface of the second engaging portion 45 are inclined relative to the horizontal plane to accommodate the pivoting of the button component 40.

[0062] Further, as a preferred embodiment, the button component 40 is pressed to release the closed state of the cover body 2. After the second hole 12 is connected to the external air, the second engaging piece 44 and the second engaging portion 45 are engaged, so that the cover body 2 is in a partially open state.

[0063] More specifically, if Figures 3 to 7 As shown, when the cover body 2 is in the closed state, the upper surface of the first engaging piece 41 is engaged with the lower surface of the first engaging portion 42 , and at this time, the force applying mechanism 43 continuously applies force to maintain the closed state.
