Instant-mix cap

An instant-mix cap, characterized in that, it comprises an upper cap, a lower cap and a sealing plug;

• and the upper cap, the lower cap and the sealing plug are enclosed to form a sealed storage chamber;
• the upper cap comprises a pushing part, a curved flexible part, an annular protection part, a pillar, an upper cap cylinder and an annular upper snap-in part which are integrally formed together, the annular protection part protrudes upward and encloses to form a protection area which is used for accommodating the pushing part and the curved flexible part, and a height of the annular protection part is larger than a height of the pushing part;
• the sealing plug is removably sealingly connected to a bottom of the lower cap for sealing the storage chamber;
• the pillar is integrally provided beneath the pushing part of the upper cap, and its lower end is fixedly connected to the sealing plug;
• when manually acting downward on the pushing part, the curved flexible part deforms and moves downward, and the pillar synchronously pushes downward the sealing plug, which causes the sealing plug to escape from blocking of a lower cap cylinder, thereby opening the storage chamber.

An instant-mix cap, characterized in that, it comprises an upper cap, a lower cap and a sealing plug, the upper cap, the lower cap and the sealing plug are enclosed to form a sealed storage chamber, wherein:

• the upper cap comprises a pushing part, an elastic part, a protection part, an upper cap cylinder and a pillar which are integrally formed together, and an edge of the pushing part extends outward and forms the elastic part, an edge of the elastic part extends away from the direction of the storage chamber, which protrudes and forms the protection part, a height of the protection part is larger than a height of the pushing part;
• the pillar is provided beneath the pushing part below, a lower end of the pillar is engaging with the sealing plug, an inner side of the edge of the protection part extends toward the direction of the storage chamber to form the upper cap cylinder;
• the lower cap comprises a lower cap cylinder and a lower cap housing, the lower cap cylinder is integrally covered onto the lower cap housing;
• a bottom of the lower cap cylinder is engaged with the sealing plug;
• an inner sidewall of the lower cap housing is connected to an outer sidewall of the upper cap cylinder, a top surface of the lower cap housing is abutted against a bottom surface of the protection part, and the connection between these surfaces is sealed and connected by ultrasonic welding;
• the pushing part can drive the elastic part to deform and move downward under the action of the external force, and the pillar synchronously pushes the sealing plug to move downward, causing the sealing plug to break the connection with the bottom of the lower cap cylinder, thereby opening the storage chamber.
