Abstract

The utility model relates to a plastic bottle, particularly a small plastic bottle for containing spice, etc. A round circular bead is mainly arranged under an external thread of a bottle mouth of the plastic bottle, and outer ratchets are arranged on circular arcs of two opposite outer edges of the round circular bead. An annular ring whose inner wall is provided with an inner ratchet are arranged under a plastic bottle cover, the upper end surface of an inner ratchet pawl is fixedly connected with the corresponding outer edge on the lower end of the plastic bottle cover, and the inner ratchet pawl matches with the outer ratchets. Therefore, the falsification of original products can be prevented.

Description

Anti-counterfeit plastic bottle

The utility model relates to a kind of plastic bottle, especially refers to debug the small plastic bottle of taste substance etc.

At present, after common plastic bottle bottle cap took off, bottle cap did not destroy, and the producer or the people that do counterfeit and shoddy goods are had an opportunity to take advantage of, and caused the confusion of product.

Sign this, the purpose of this utility model provides a kind of anti-counterfeit plastic bottle, and it covers use again after bottle cap takes off, and still, can not recover the state of original bottle cap.

The purpose of this utility model is achieved in that a kind of anti-counterfeit plastic bottle comprises plastic bottle and plastic bottle closure, wherein the bottleneck of plastic bottle has outside thread, has the negative thread that matches with outside thread in the plastic bottle closure, it is characterized in that: below the outside thread of plastic bottle bottleneck, be provided with round platform shoulder, and two sections relative outer rim circular arcs of this round platform shoulder are provided with outer ratchet; It is affixed that the plastic bottle closure below is provided with the corresponding outer rim with the plastic bottle closure lower end of ring and the interior ratchet upper surface place that has interior ratchet on its inwall, should match with outer ratchet by interior ratchet again.

Owing to adopt such scheme: resilient not again after bottle cap takes off, can prevent that therefore puppet from emitting original product, stop fake products.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 the utility model exemplary embodiments scheme drawing.

The A-A section-drawing of Fig. 2 the utility model exemplary embodiments Fig. 1.

Among the figure:

1, plastic bottle, 11, round platform shoulder, 111, outer ratchet,

2, plastic bottle closure, 21, ring, 211, interior ratchet.

Present embodiment comprises plastic bottle 1 and plastic bottle closure 2, as shown in Figure 1, and wherein:

The bottleneck of plastic bottle 1 has the round platform shoulder 11 of outside thread and this outside thread below, this round platform take on 11 two sections relative, the outer rim circular arc is provided with outer ratchet 111;

Has the negative thread that matches with outside thread in the plastic bottle closure 2; Have the interior ratchet 211 that matches with the outer ratchet 111 of round platform shoulder 11 on ring 21 inwalls and be somebody's turn to do the interior places of corresponding outer rim with plastic bottle closure 2 lower ends, ratchet 211 upper surfaces affixed (fusing) and formation dowel, the i.e. gapped slit of formation between bottle cap 2 lower ends and ring 21 upper ends.

The operation of present embodiment and principle of work:

When the clockwise direction of exerting oneself slightly rotates plastic bottle closure 2, be that plastic bottle closure 2 unclamps (outside thread, negative thread are right-hand screw thread), and the outer ratchet 111 of the interior ratchet 211 of ring 21 and round platform shoulder 11 match (leaning), therefore ring 21 can not be had only the dowel of interior ratchet 211 upper surfaces and plastic bottle closure 2 lower end outer rims to break by turn.

Claims

1, a kind of anti-counterfeit plastic bottle comprises plastic bottle (1) and plastic bottle closure (2), wherein the bottleneck of plastic bottle 1 has outside thread, plastic bottle closure has the negative thread that matches with outside thread in (2), it is characterized in that: the outside thread below at plastic bottle (1) bottleneck is provided with round platform shoulder (11), and two sections relative outer rim circular arcs of this round platform shoulder (11) are provided with outer ratchet (111); It is affixed with corresponding outer rim place, plastic bottle closure (2) lower end that plastic bottle closure (2) below is provided with the ring (21) and interior ratchet (211) upper surface that have interior ratchet (211) on its inwall, should match with outer ratchet (111) by interior ratchet (211) again.
