Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

The double-seal overflow bottle cap comprises a main cap 1 and an upper inner cap 2; the main cover is provided with an inner pipe 12 penetrating through a top wall 17, a lateral overflow hole 13 is arranged on the part of the inner pipe 12 higher than the top wall 17 of the main cover, and a plurality of longitudinal guide grooves 14 are arranged at the lower part of the inner pipe 12; the outer peripheral surface of the upper inner cover 2 is in sealing fit with the inner peripheral surface of the main cover inner tube, the lower part of the upper inner cover is provided with a plurality of longitudinal clamping hook strips 24 which are matched with the longitudinal guide grooves 14 at the lower part of the main cover inner tube, and the longitudinal guide grooves 14 play a limiting role on the longitudinal clamping hook strips 24, so that the upper inner cover 2 can slide up and down in the main cover inner tube 12 but cannot be pulled out; when the upper inner cover 2 is downwards positioned at a covering position, the inner pipe part below the overflow hole 13 is sealed, and liquid cannot flow out; when the upper inner cover 2 is in the pulled-up position, the inner pipe part above the overflow hole 13 is still sealed, and the overflow hole 13 is exposed, and liquid can flow out from the overflow hole. The upper part of the upper inner cover is provided with a hand-held component.

The two overflow holes 13 are symmetrical, so that on one hand, the operation is convenient, and both sides of the bottle can discharge liquid; on the other hand, the overflow holes on the opposite side of the actual liquid outlet can enter air, so that negative pressure in the bottle is avoided when the liquid is discharged, and the liquid can be discharged smoothly. The number of the hook strips 24 and the guide grooves 14 is four.

The outer wall of the main cover extends upwards to be higher than the overflow hole 13, the top surface 11 and the inner pipe 12 are transversely connected into a whole, and the overflow hole 13 penetrates through the inner pipe 12 and the outer wall of the main cover. The overflow holes 13 extend outwardly beyond the outer wall of the main cap, thus preventing liquid from flowing down along the outer wall of the main cap.

As shown in the perspective view of fig. 3. A pair of wing plates 25 are extended from the top wall of the upper inner cap 2 to two sides in the direction vertical to the overflow hole 13 to be flush with the edge of the main cap, and the top surface 11 of the main cap is sunken to accommodate the top surface 21 of the upper inner cap, so that the top surface of the whole bottle cap is flush; the main cover below the edge of the wing plate of the upper inner cover is concave so as to facilitate the two ends of the hand-held wing plate 25 to pull up the upper inner cover 2.

The main cover 1 and the upper inner cover 2 are respectively integrally formed by injection molding.

The main cover 1 is internally provided with a sealing flat gasket 15 for sealing with the upper edge of the bottle mouth; the outer periphery of the upper inner cover 2 is provided with an annular groove 22, and a sealing ring 23 is arranged in the annular groove and used for enhancing the sealing with the inner pipe 12 of the main cover.

The main cover 1 is matched with the bottle mouth 3 in a clamping way, and the lower part of the peripheral surface of the main cover 1 is provided with an inward hook 17 which is clamped with a step 31 at the lower part of the bottle mouth 3. The cooperation of the structure ensures that the main cover and the bottle are in a normally closed state. Of course, the main cap 1 can be engaged with the bottle mouth 3 by a conventional screw-thread engagement.
