Description

Technical Field

[0001] The present invention relates to a bottle cap for a beverage container, and particularly to a bottle cap for a beverage container that forms a closed or open state by the cooperation of a pivoting valve body and a waterproof gasket. Background Art

[0002] The applicant of the present invention already owns the US Patent No. US 9,573,738 B1 (simultaneously obtained the Chinese Patent No. CN205132001U), which is a bottle cap for a beverage container mainly using the cooperation of a pivoting valve body and a waterproof gasket to form a closed or open state, and a liquid through-hole and at least one air through-hole are integrally formed on the waterproof gasket at the same time. Therefore, there is no need to separately manufacture a special waterproof gasket with an air through-hole, thereby solving the problems that the special waterproof gasket is not easy to be installed on the air through-hole of the cap body and is likely to fall off or even be swallowed during use. However, when the beverage container contains carbonated beverages (such as cola) or high-temperature beverages (such as hot coffee) and other types of beverages, it is easy to generate and accumulate high air pressure inside the beverage container. When the pivoting valve body is pivoted from the closed state at the first pivoting position to the open state at a second pivoting position, the high air pressure inside the beverage container will cause the carbonated beverage or high-temperature beverage inside the beverage container to spray outwards from the water outlet of the pivoting valve body, causing unexpected injuries to the user on the spot, such as soiling clothes or scalding. Summary of the Invention

[0003] The main object of the present invention is to provide a bottle cap for a beverage container, including a cap body, a pivoting valve body and a waterproof gasket. The pivoting valve body includes a hemispherical pivoting portion with a hemispherical surface. When the pivoting valve body is pivoted to a first pivoting position, at least one flange on the periphery of the hemispherical surface tightly closes the air through-hole of the waterproof gasket. A long groove with a notch facing outwards and having a front end and a relative rear end is arranged on the surface of each flange along the pivoting direction. When the pivoting valve body is pivoted away from the first pivoting position, the front end of each long groove can communicate with the air through-hole of the waterproof gasket, so that the air inside the beverage container can be communicated to the outside through each long groove and the rear end of each long groove, effectively solving the problem that the beverage in the beverage container sprays outwards from the water outlet of the pivoting valve body due to high air pressure.

[0004] To achieve the above object, the present invention provides a bottle cap for a beverage container, the bottle cap including a cap body, a pivoting valve body and a waterproof gasket;

[0005] The cover is detachably assembled to the upper opening of a beverage container. A valve seat is provided on the top surface of the cover. The valve seat has a chamber. A liquid through-hole is provided at a position on the bottom of the chamber. The liquid through-hole penetrates through the cover to communicate with the interior of the beverage container. The liquid through-hole has a liquid through-hole edge, and at least one air through-hole is provided around the liquid through-hole edge.

[0006] The waterproof gasket is correspondingly fixed at the position of the liquid through-hole or the liquid through-hole edge provided at the bottom of the chamber. A liquid through-hole is provided on the waterproof gasket to correspondingly communicate with the liquid through-hole of the cover. The liquid through-hole has a liquid through-hole edge, and at least one air through-hole is provided around the liquid through-hole edge to correspondingly communicate with the air through-hole provided around the liquid through-hole edge of the cover.

[0007] The pivot valve body is pivotally arranged in the chamber of the valve seat. The pivot valve body includes a hemispherical pivot portion and a nozzle portion. The hemispherical pivot portion is located at the bottom of the pivot valve body and has a hemispherical surface. The nozzle portion extends from the hemispherical pivot portion. The hemispherical surface of the hemispherical pivot portion can be tightly pressed against the liquid through-hole of the waterproof gasket, and the hemispherical surface can pivot synchronously with the pivot valve body to pivot from a first pivot position to a second pivot position or pivot in the reverse direction. Wherein a flow channel is provided inside the nozzle portion. Two ends of the flow channel respectively form a water inlet and a water outlet. The water inlet is located on the hemispherical surface of the hemispherical pivot portion, and the water outlet is located at one end of the nozzle portion opposite to the pivot portion for a user to suck and drink. At least one flange is provided at a predetermined position around the hemispherical surface of the hemispherical pivot portion; when the pivot valve body is pivoted to the first pivot position, the water inlet on the hemispherical surface of the pivot valve body leaves the liquid through-hole of the waterproof gasket, and the hemispherical surface tightly closes the liquid through-hole of the waterproof gasket. At the same time, each flange provided around the hemispherical surface tightly closes the air through-hole of the waterproof gasket, so that the bottle cap forms a closed state; when the pivot valve body is pivoted to the second pivot position, the water inlet on the hemispherical surface of the pivot valve body aligns with the liquid through-hole of the waterproof gasket to form a communication state. At the same time, each flange provided around the hemispherical surface leaves the air through-hole of the waterproof gasket, so that the air through-hole of the waterproof gasket can communicate with the outside through the air through-hole provided on the cover, so that the bottle cap forms an open state; It is characterized in that:

[0008] A long groove with a notch facing outwards is provided along the pivot direction on the surface of each flange around the hemispherical surface of the pivot valve body. Each long groove has a front end portion and a relative rear end portion; when the pivot valve body is pivoted from the first pivot position to leave the first pivot position, the front end portion of each long groove can communicate with the air through-hole of the waterproof gasket, so that the air inside the beverage container can communicate with the outside through each long groove and the rear end portion of each long groove.

[0009] The waterproof gasket further has a concave arc surface, and the concave arc surface can be correspondingly attached to the hemispherical surface of the pivot valve body; during the pivoting process in which the pivot valve body is pivoted from the first pivot position to the second pivot position or pivoted in the reverse direction, the hemispherical surface of the pivot valve body slides while being attached to the concave arc surface.

[0010] Both the cover body and the pivot valve body are integrally formed bodies by plastic injection molding.

[0011] The waterproof gasket is an integrally formed body molded from silica gel.

[0012] On the two corresponding inner walls of the accommodation chamber of the valve seat, opposite pivot grooves are respectively provided, and on the two opposite side surfaces of the pivot valve body, a pivot shaft is respectively protruded to be pivotally connected to each of the pivot grooves.

[0013] The valve seat is recessed downward and is provided below the top surface of the cover body.

[0014] The advantage of the present invention is that it can effectively solve the problem that the beverage in the beverage container will spray outwards from the water outlet of the pivot valve body due to high air pressure. Description of the Drawings
