Beverage container apparatus
The present disclosure relates to a food and beverage container device including: a container for storing food and beverage, and a piston unit capable of moving up and down in close contact with the container. The piston unit includes a neck part having a hollow interior and movable up and down. The neck part includes a discharge portion protruding upward from an upper end of the neck part, having a first threaded portion and a first discharge groove on the outer circumferential surface, and discharging food and beverage or air to the inside of the container, a first flow guiding portion formed to be inclined upward in the opposite direction to the first discharge groove at a position spaced apart from the discharge portion, and a first reservoir portion formed between the discharge portion and the first flow guiding portion to hold the discharged food and beverage.
1. A food and beverage container device comprising:
a container configured to store food and beverage; and
a piston unit configured to move in a vertical direction in close contact with an inner surface of the container,
wherein the piston unit comprises a neck part having a hollow interior and movable in the vertical direction,
the neck part comprises:
a discharge portion protruding upward from an upper end of the neck part and having a first discharge groove in an outer circumferential surface to discharge the food and beverage or air in the container;
a first flow guiding portion formed to be inclined upward in a direction opposite to the first discharge groove at a position spaced apart from the discharge portion;
a second flow guiding portion formed on a portion of an outer circumferential surface of the upper end of the neck part to be inclined upward;
a flow prevention protruding upward from the second flow guiding portion;
an outlet connected to the second flow guiding portion and formed on a portion of the outer circumferential surface of the upper end of the neck part to be inclined downward toward a front end; and
a second reservoir portion formed between the outlet and the first flow guiding portion to hold the discharged food and beverage.
2. The food and beverage container device of claim 1 , wherein the neck part comprises a first reservoir portion formed between the discharge portion and the first flow guiding portion to hold the discharged food and beverage.
3. A food and beverage container device comprising:
a container configured to store food and beverage; and
a piston unit configured to move in a vertical direction in close contact with an inner surface of the container,
wherein the piston unit comprises a neck part having a hollow interior and movable in the vertical direction,
the neck part comprises a discharge portion protruding upward from an upper end of the neck part and having a first discharge groove in an outer circumferential surface and a second discharge groove in communication with the first discharge groove in a lower end thereof to discharge the food and beverage or air in the container,
the piston unit further comprises:
a discharge pipe that is a passage which is accommodated in the neck part and inserted and coupled to the second discharge groove and through which the food and beverage in the container move;
an inner cap having a groove at one end to which the discharge pipe is coupled; and
a blocking cap inserted and coupled to the other end of the inner cap and having a fourth discharge groove at one end,
wherein a center of the fourth discharge groove is deviated from a center of the groove of the inner cap when the blocking cap is inserted and coupled to the inner cap.
