[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0028] This embodiment discloses a one-button-opening milk powder cap, such as... Figures 1 to 3 As shown, it includes an upper cover 1, a lower cover 3, a push switch 2, and a torsion spring 4; wherein the upper cover 1 and the lower cover 3 are hinged to each other by a hinge shaft, the lower cover 3 has a push groove 31 at the end away from the hinge shaft, the upper cover 1 has a second buckle 11 fixed at the end away from the hinge shaft, and the torsion spring 4 is sleeved on the hinge shaft of the upper cover 1 and the lower cover 3, and the two ends of the torsion spring 4 are fixedly connected to the upper cover 1 and the lower cover 3 respectively, so as to drive the upper cover and the lower cover to rotate and open around the hinge shaft.

[0029] like Figure 4 and Figure 5 As shown, the push-button switch 2 includes a push-button cap 21, a push-button spring 22, a guide boss 25, and a first latch 23. The push-button cap 21 is located in the push-button groove 31. Two push-button springs 22 are provided, with their two ends fixedly connected to the push-button cap 21 and the bottom of the push-button groove 31, respectively. The first latch 23 is fixedly mounted on the push-button cap 21. The push-button cap 21 has a through hole 26 for the latching end of the first latch 23 to pass through. The first latch 23 is a V-shaped latch with its tip facing downwards. The latching end of the first latch 23 passes through the through hole 26 and engages with the second latch 11. Figure 6 As shown, the first buckle 23 is divided into left and right parts by the bend line at its tip, with the buckling end of the first buckle 23 located on the right part of the first buckle 23.
