[0021] In order to make the purpose, characteristics and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below with reference to the drawings. The drawings show several embodiments of the utility model. However, the utility model can be realized in many different forms, and is not limited to the embodiments described herein.

[0022] The utility model is described in detail below with reference to the drawings and embodiments.

[0023] The utility model provides a powder cover with anti-opening function, as shown in Figures 1-5 The utility model provides a powder cover with anti-opening function, as shown in

[0024] Specifically, the top and bottom of the screw cap 1 are respectively formed with the stab-proof ring 11 and the anti-theft ring 13 by an injection molding process, the bottom of the stab-proof ring 11 and the top of the anti-theft ring 13 are connected with the screw cap 1 through a plurality of tear strips (not shown in the figure), so that the stab-proof ring 11 and the anti-theft ring 13 can be separated from the screw cap 1 under the action of an external force. In addition, the inside of the screw cap 1 is provided with an internal thread for adapting to the bottle mouth. The button 3 is installed on the screw cap 1 after passing through the stab-proof ring 11 from bottom to top, the top edge of the button 3 is provided with a limiting ring (not shown in the figure), and the middle part is provided with a plurality of clamping blocks 35 for preventing the button 3 from falling off the screw cap 1, the button 3 is rotatably installed on the screw cap 1 under the action of the clamping blocks 35 and the limiting ring. The powder bin 2 is installed in the inside of the screw cap 1 and covers the middle and lower part of the button 3 through a snap-fit structure of clamping protrusions and clamping grooves, and the sheet 21 is installed at the bottom of the powder bin 2 through an integral injection molding process or a welding process; when the sheet 21 is an aluminum foil, it is fixed at the bottom of the powder bin 2 through an ultrasonic welding process; when the sheet 21 is a plastic material, it is integrally formed with the powder bin 2.

[0025] The process of taking the powder cap off the beverage bottle is as follows: the stab-proof ring 11 is torn open, the button 3 is pressed to pierce the film 21, the powder in the powder bin 2 falls into the bottle body, the bottle body is shaken until the powder is completely dissolved in the liquid, and the screw cap 1 is rotated to take the powder cap off the beverage bottle (as shown in Figure 6 ).

[0026] The utility model discloses a stab-proof ring 11 is additionally arranged on the top of the screw cap 1, so that the stab-proof ring 11 can clamp the button 3 before being torn off, which prevents the button 3 from sliding to the powder bin 2 and piercing the sheet 21, thereby solving the technical problem that the powder cap can be pierced in advance during transportation or handling.

[0027] Further, a tear groove 111 is formed in the side wall of the stab-proof ring 11 to facilitate tearing the stab-proof ring 11 into a strip shape.

[0028] Further, a tear handle 112 is arranged on the side wall of the stab-proof ring 11 to facilitate separating the stab-proof ring 11 from the screw cap 1.

[0029] As shown in Figures 1-2 , in order to facilitate the user to take the stab-proof ring 11 off the screw cap 1, a tear groove 111 is formed in the side wall of the stab-proof ring 11, and the length of the tear groove 111 extends to the top and bottom of the stab-proof ring 11. The tear handle 112 is located on one side of the stab-proof ring 11 and at the top of the stab-proof ring 11. When the user pinches the tear handle 112 and pulls it down, the tear groove 111 is divided into two parts, the tear strip at the bottom of the stab-proof ring 11 is also broken, and the entire stab-proof ring 11 is separated from the screw cap 1. When the stab-proof ring 11 is not torn open, it can prevent the button 3 from being pressed and prevent accidental triggering.

[0030] Further, a plurality of deformation grooves 113 are formed on the sidewall of the stab-proof ring 11 to facilitate the deformation of the top of the stab-proof ring 11 and the installation of the button 3 on the screw cap 1.

[0031] As shown in Figures 1-5 the deformation grooves 113 extend from the middle lower end of the stab-proof ring 11 to the top thereof, and the upper middle end of the stab-proof ring 11 is formed as a thin-walled position; when the button 3 is installed from the bottom of the screw cap 1 upwards, the diameter of the top limiting ring of the button 3 is larger than that of the top of the stab-proof ring 11, and therefore a plurality of thin-walled positions are arranged on the outer side of the stab-proof ring 11; during the assembly process, the thin-walled positions are easily stretched and expanded, facilitating the installation of the top of the button 3.

[0032] Further, a powder cavity 31 is formed in the button 3 to increase the powder storage capacity.

[0033] As shown in Figures 1-5 the utility model has two assembly methods, which are method (1): the button 3 is installed on the screw cap after being passed through the stab-proof ring 11 from bottom to top, the powder is poured into the powder bin 2, and the screw cap 1 is buckled on the powder bin 2; method (2): the button 3 is installed on the screw cap after being passed through the stab-proof ring 11 from bottom to top, the button 3 is reversed, the powder is poured into the powder cavity 31, and the powder bin 2 is buckled on the screw cap 1. Relatively speaking, method (2) is more convenient to assemble, because the powder does not hinder the button 3 to enter or exit the inside of the powder bin 2.

[0034] In addition, the assembly process of the utility model does not need to use ultrasonic welding equipment, and compared with the CN211282104U2 patent disclosed press type powder cover, it is beneficial for beverage manufacturers to save production cost. When the beverage manufacturers do not purchase ultrasonic welding equipment, they can only entrust external agencies to carry out powder filling and welding sealing. In addition, the ultrasonic welding process may produce high temperature or irritating gas, which may cause part of the powder to fail. The powder cover assembly process of the present application can be completely carried out in the beverage factory, and the flexibility of switching the powder type is also high; the assembly process does not produce high temperature or irritating gas, and the safety is higher.

[0035] Further, as shown in Figure 4 the sheet 21 is pierced by the button 3, the bottom of the button 3 is provided with a piercing slope 32, and the piercing convex point 33 is arranged at the lowest point of the piercing slope 32 to facilitate the piercing of the sheet 21 by the piercing slope 32. In order to prevent the sheet 21 from falling into the beverage, the anti-falling groove 34 is arranged at the highest point of the piercing slope 32 to prevent the sheet 21 from falling off from the bottom of the powder bin 2. When the piercing slope 32 cuts the sheet 21 to a certain extent, the sheet 21 is pushed out downward by the outside slope of the piercing convex point 33, and the anti-falling groove 34 can prevent the remaining uncut sheet 21 from being connected to the powder bin 2, that is, the anti-falling groove 34 plays a role of accommodating the connection position of the sheet 21.

[0036] Furthermore, the top edge of the powder hopper 2 is provided with serrations 22, and several slots 12 are provided inside the cap 1 at positions corresponding to the serrations 22.

[0037] like Figures 4-5 As shown, the top edge of the powder container 2 is integrally formed with annular ratchet teeth 22, and several corresponding slots 12 are provided inside the screw cap 1. This structural design allows the powder container 22 to fold inward clockwise when the powder container 2 is fastened onto the screw cap 1 during assembly, producing a "clicking" sound, making it easy to determine that the powder container 2 and the screw cap 1 are properly installed. When removing the powder cap, the screw cap 1 rotates counterclockwise, which in turn drives the ratchet teeth 22 to rotate, making it easier to move the powder container 2 away from the bottle opening and remove it along with the powder cap.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
