DETAILED DESCRIPTION

[0028] See also Figure 1-Figure 8 As shown, the technical solution adopted in this specific embodiment is: a double-sealed food packaging bottle, including a bottle body 1, a bottle cap 2 is detachably connected to the upper end of the bottle body 1, a sealing cover 3 is detachably connected to the upper end of the bottle cap 2, an upwardly protruding anti-counterfeiting boss 25 is arranged in the middle of the bottle cap 2, a liquid outlet 4 is opened in the middle of the anti-counterfeiting boss 25, a cross silicone valve 5 is arranged on the bottom surface of the liquid outlet 4, a fixed sealing ring 6 is arranged on the edge of the bottom surface of the cross silicone valve 5, the cross silicone valve 5 is fixedly installed on the bottom surface of the liquid outlet 4 through the fixed sealing ring 6, and the fixed sealing ring 6 also plays the role of edge sealing to prevent liquid from leaking from the edge of the cross silicone valve 5, and a sealing cap 7 is arranged in the middle of the bottom surface of the sealing cover 3 corresponding to the liquid outlet 4.

[0029] When the sealing cover 3 is connected to the bottle cap 2, the sealing cap 7 will block the liquid outlet. The sealing cap 7 can provide an extra layer of sealing and protection for the liquid outlet 4 to prevent the liquid from flowing out between the sealing cover and the bottle cap when the cross silicone valve 5 is damaged.

[0030] The cross silicone valve 5 includes a silicone diaphragm 51, and a cross cut 52 is opened in the middle of the silicone diaphragm 51. The cross silicone valve 5 has a simple structure, low cost, and sensitive control. The bottle body 1 is gently squeezed to compress the space inside the bottle body 1, and the liquid applies pressure to the cross silicone valve 5, so that the cross cut 52 on the silicone diaphragm 51 can be opened, and the liquid flows out from the liquid outlet 4; if the bottle body is not squeezed, the cross cut 52 will be immediately closed to prevent the liquid from continuing to flow out of the head, so that the user can easily control the outflow amount of the liquid by hand gripping.

[0031] Wherein, the cross silicone valve 5 is made of food grade FDA&LFGB liquid silicone rubber material.

[0032] Among them, a bottle body connector 11 is arranged at the upper edge of the bottle body 1, and a bottle cap lower connector 23 detachably connected to the bottle body connector 11 is arranged at the lower edge of the bottle cap 2.

[0033] The outer peripheral wall of the bottle body connecting head 11 is provided with a bottle body connecting external thread 12 , and the inner peripheral wall of the bottle cap lower connecting head 23 is provided with a bottle cap connecting internal thread 24 matching with the bottle body connecting external thread 12 .

[0034] The upper end of the bottle body 1 is detachably connected to the lower end thread of the bottle cap 2 through the cooperation of the bottle body connecting external thread 12 and the bottle cap connecting internal thread 24 .

[0035] The upper edge of the bottle cap 2 is provided with a bottle cap upper connector 21 , and the lower edge of the sealing cap 3 is provided with a sealing cap connector 31 detachably connected to the bottle cap upper connector 21 .

[0036] The outer peripheral wall of the bottle cap upper connector 21 is provided with a bottle cap connecting external thread 22 , and the inner peripheral wall of the sealing cap connector 31 is provided with a sealing cap connecting internal thread 32 matched with the bottle cap connecting external thread 22 .

[0037] The upper end of the bottle cap 2 is detachably connected to the lower end thread of the sealing cap 3 through the cooperation of the bottle cap connecting external thread 22 and the sealing cap connecting internal thread 32 .

[0038] The bottle cap 2, the sealing cap 3 and the bottle body 1 are all detachably connected by threads, which is convenient to use and replace.

[0039] The bottle body 1 is a transparent bottle body, which allows for easy observation of the liquid level inside.

[0040] The working principle of the utility model is as follows: before use, unscrew the bottle cap to pour the liquid into the bottle body, and then select the bottle cap; when not in use, screw the sealing cap on the bottle cap, the sealing cap will block the liquid outlet, and an extra layer of sealing and protection will be provided to the liquid outlet; when in use, unscrew the sealing cap, with the liquid outlet facing downward, squeeze the liquid in the bottle body to flow out from the cross cutout in the cross silicone valve, due to the setting of the cross silicone valve, leakage and bifurcation are not likely to occur when pouring out the liquid, and the liquid outflow amount can be simply controlled. When the bottle is tilted and the sealing cap is not screwed on, due to the setting of the cross silicone valve, the liquid in the bottle is prevented from flowing out due to the tilt of the bottle body, and leakage will not occur, and the overall sealing performance is better.
