Anti-theft plastic bottle cap

Abstract

An anti-theft plastic bottle cap contains a body and an anti-theft ring. The body is connected on an opening of a bottle. The anti-theft ring is mounted on a bottom of the body, and multiple equidistant connection teeth are formed between the body and the anti-theft ring. The body includes a first protrusion extending to the anti-theft ring from a bottom of the body, and the anti-theft ring includes two second protrusions extending to the body. The first protrusion is engaged with the two second protrusions when the body is rotated clockwise, such that the anti-theft plastic bottle cap is not rotated overly by using the first protrusion and the two second protrusions to avoid a removal of the anti-theft ring from the body and the anti-theft ring before a user detaches the anti-theft plastic bottle cap from the bottle.

Claims

1. An anti-theft plastic bottle cap comprising; a body configured to be connected on an opening of a bottle; an anti-theft ring mounted on a bottom of the body; and multiple equidistant connection teeth between the body and the anti-theft ring, wherein the body includes a first protrusion extending to the anti-theft ring from the bottom of the body, and the anti-theft ring includes two second protrusions extending to the body, wherein the multiple equidistant connection teeth each extend from a top surface of the two second protrusions, wherein when the body is rotated counterclockwise, the multiple equidistant connection teeth are removed, allowing a user to determine that the bottle has been opened, and, wherein when the body is rotated clockwise, the first protrusion engages with the two second protrusions, such that the anti-theft plastic bottle cap is not rotated overly by using the first protrusion and the two second protrusions to avoid a removal of the anti-theft ring from the body and the anti-theft ring before the user detaches the anti-theft plastic bottle cap from the bottle.

2. The anti-theft plastic bottle cap as claimed in claim 1, wherein the anti-theft plastic bottle cap is connected on an eye drop bottle.

3. The anti-theft plastic bottle cap as claimed in claim 1, wherein the anti-theft plastic bottle cap is connected on a medicine bottle.

(5) FIG. 5 is a perspective view showing the application of the anti-theft plastic bottle cap according to the preferred embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(6) With reference to FIGS. 2 to 5, an anti-theft plastic bottle cap according to a preferred embodiment of the present invention is capable of avoiding a removal before a user detaches the anti-theft plastic bottle cap, and the anti-theft plastic bottle cap is applicable for a variety of bottles (such as eye drop bottles or medicine bottles) made of plastic. In this embodiment, the anti-theft plastic bottle cap is applicable for an eye drop bottle. However, in another embodiment, the anti-theft plastic bottle cap is applicable for a medicine bottle.

(7) Referring to FIG. 5, the anti-theft plastic bottle cap 10 comprises a body 1 and an anti-theft ring 2, wherein the body 1 is connected on an opening of a bottle 3. As shown in FIG. 2, the anti-theft ring 2 is mounted on a bottom of the body 1, and multiple equidistant connection teeth 4 are formed between the body 1 and the anti-theft ring 2, such that after the body 1 is rotated counterclockwise to remove from the multiple equidistant connection teeth 4, the user learns the bottle 3 is opened or is not opened by distinguishing whether the body 1 is removed from the multiple equidistant connection teeth 4 or not.

(8) As illustrated in FIGS. 3 and 4, the body 1 includes a first protrusion 5 extending to the anti-theft ring 2 from a bottom of the body 1, and the anti-theft ring 2 includes two second protrusions 6 extending to the body 1, wherein the first protrusion 5 is engaged with the two second protrusions 6 when the body 1 is rotated clockwise, such that the anti-theft plastic bottle cap 10 is not rotated overly by using the first protrusion 5 and the two second protrusions 6 to avoid a removal of the anti-theft ring 2 from the body 1 and the anti-theft ring 2 before the user detaches the anti-theft plastic bottle cap from the bottle.

(9) Preferably, when the anti-theft plastic bottle cap 10 is connected on the bottle 3 by way of a packing machine (not shown), the first protrusion 5 is engaged with the two second protrusions 6 to avoid the anti-theft plastic bottle cap 10 is rotated overly, thus preventing the removal of the multiple equidistant connection teeth 4 from the body 1 and the anti-theft ring 2 before the user detaches the anti-theft plastic bottle cap 10 from the bottle 3.

(10) While the preferred embodiments of the invention have been set forth for purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
