Anti-fake bottle cap opened after being ejected

Abstract

The invention designs an anti-fake bottle cap opened after being ejected, solving the technical problem that the existing anti-fake structures are not reasonable in design and have short ejection height, large twist-off force and poor anti-fake effects. The anti-fake bottle cap comprises an outer sleeve and an inner sleeve, wherein the inner sleeve is located in the outer sleeve with top. The anti-fake bottle cap is characterized in that a lead sleeve which carries out rotary transmission with the outer sleeve is arranged between the inner sleeve and the outer sleeve; the lead sleeve is provided with a spiral groove; an ejection part is arranged in the inner sleeve; the side wall of the ejection part is provided with a poking head and the upper end thereof is provided with a seal cap; the poking head runs through a vertical groove on the side wall of the inner wall and is matched with the spiral groove on the lead sleeve; and the outer sleeve rotates relative to the inner sleeve in single direction. The anti-fake bottle cap has the following advantages: the ejection height of the ejection part is long; the seal cap is convenient to open and close; the twist-off force is small; the ejection part no longer restores after being ejected and has obvious anti-fake effect; assembly is convenient; and the anti-fake structure is hidden inside, thus being not easy to damage or artificially destroy.

Description

technical field [0001] The invention relates to an anti-counterfeit bottle cap, in particular to a push-out and re-open type anti-counterfeit bottle cap. Background technique [0002] The current anti-counterfeit bottle caps on the market are unreasonable in structure design, with short ejection height, large unscrewing force, single liquid outlet style, and troublesome assembly. The ejector parts can be restored after ejection and some parts of the cap are exposed. The problem of poor anti-counterfeiting effect. For example, the patent (notification number: CN201089573Y) authorized and announced on July 23, 2008 lacks a cover inside the ejector structure. After opening, the ejector must be restored to its original position to prevent the remaining liquid from flowing out.

Problems solved by technology

[0002] The current anti-counterfeit bottle caps on the market are unreasonable in structure design, with short ejection height, large unscrewing force, single liquid outlet style, and troublesome assembly. The ejector parts can be restored after ejection and some parts of the cap are exposed. The problem of poor anti-counterfeiting effect

For example, the patent (notification number: CN201089573Y) authorized and announced on July 23, 2008 lacks a cover inside the ejector structure. After opening, the ejector must be restored to its original position to prevent the remaining liquid from flowing out. Affects the anti-counterfeiting effect; moreover, the structure of the patent (the inner wall of the ejector and the outer wall of the conduit uses a polygon to stop rotation) brings difficulty to the assembly during production, because the polygon has an assembly position, and it can be installed in any direction, and when it is opened It is easy to reverse and deflect due to external force, resulting in poor sealing, resulting in liquid leakage, and the thread design of the outer body and inner ejector also brings difficulties to assembly

It is worth pointing out that if the ejector can return to its position after being ejected, that is, it can move in both directions, and there is a possibility and opportunity to repair the bottle cap, and it is impossible to avoid the bottle cap that should be used once. It is difficult to guarantee the expected anti-counterfeiting Effect
