Plastic security cap

Abstract

This utility model discloses a plastic anti-theft cap, relating to the field of plastic bottle cap production and processing technology. It includes a cap body, a support plate fixedly installed inside the cap body, an anti-theft label cap slidably mounted on the cap body, a disposable sealing strip fixedly mounted on the anti-theft label cap and the cap body, an indicator pointer fixedly mounted on the anti-theft label cap, and several scale lines on the cap body. An anti-theft label structure is provided on the support plate. First, the disposable sealing strip is removed. Then, the anti-theft label cap is rotated until the indicator pointer points to the desired scale line. Next, the anti-theft label cap is pressed to release the restriction between the bottom of the limiting post and the thin plate 18. The anti-theft label cap is continuously pressed until the limiting bead engages in the annular groove, thus locking the limiting post. This solves the problem in existing technologies where the annular ring used for marking can rotate multiple times, affecting the anti-theft labeling effect of the cap.

[0003] Chinese utility model patent CN221091978U discloses an anti-theft plastic bottle cap: comprising a cap body, a connecting bridge, and an anti-theft ring. The cap body and the anti-theft ring are fixed together by the connecting bridge. The inner sidewall of the cap body is provided with internal threads. The inner sidewall of the anti-theft ring is provided with multiple anti-theft buckles. A sealing ring plug is fixedly installed on the inner top wall of the cap body. A sealing gasket is fixedly installed on the inner top wall of the sealing ring plug. The outer wall of the sealing ring plug is integrally formed with a first sealing protrusion. By rotating the ring, the corresponding identification mark can be aligned with the indicator arrow, so that the cap body has an identification effect and can distinguish which bottle belongs to the user according to the identification mark set in advance.

[0004] However, existing technologies still have shortcomings:

[0005] The above-mentioned design allows the corresponding identification mark to match the indicator arrow by rotating the ring, but the ring can be rotated multiple times, affecting the anti-theft marking effect of the cover. Utility Model Content

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] like Figure 1-7 As shown, a plastic anti-theft cap includes a cap body 1, with a support plate 9 fixedly installed inside the cap body 1, dividing the cap body 1 into two parts. The upper part of the support plate 9 is used to install the anti-theft label structure, and the lower part of the support plate 9 is used to connect with the bottle body. The cap body 1 has an internal thread 3 for tightening with the bottle mouth. A rubber ring 4 is fixedly installed at the lower end of the cap body 1 to increase the sealing of the cap body 1 during installation. An anti-theft label 2 is slidably installed on the cap body 1, and the anti-theft label 2 is slidably installed above the support plate 9. A disposable sealing strip 7 is fixedly installed on the anti-theft label 2 and the cap body 1 to achieve a fixed connection between the cap body 1 and the anti-theft label 2 in the initial state. An indicator pointer 8 is fixedly installed on the anti-theft label 2. Several scale lines 6 are opened on the cap body 1, and the scale lines 6 are located at the end of the cap body 1 near the anti-theft label 2. Specifically, a number label (not shown in the figure) is fixedly installed below the scale lines.

[0029] In one embodiment of this invention, an anti-theft identification structure is provided on the support plate 9. The anti-theft identification structure includes a limiting post 10 and a conical positioning seat 13. The conical positioning seat 13 is fixedly disposed in the middle of the support plate 9. One end of the limiting post 10 is fixedly connected to the anti-theft identification cover 2, and the other end is movably disposed in the conical positioning seat 13. A first movable sleeve 14 and a second movable sleeve 16 are movably disposed in the conical positioning seat 13. The second movable sleeve 16 is sleeved in the first movable sleeve 14, and the first movable sleeve 14 is fixedly disposed in relation to the support plate 9. A spring 17 is fixedly installed. Several limiting beads 15 are movably arranged between the first movable sleeve 14 and the second movable sleeve 16. An annular groove 11 is opened on the limiting post 10. The length of the annular groove 11 is equal to the diameter of the limiting bead 15. Anti-slip texture is opened in the annular groove 11. In the initial state, the anti-theft label cover 2 is fixedly connected to the cover body 1 by a disposable sealing strip 7. The part of the limiting post 10 without the annular groove 11 is in contact with the limiting bead 15. The bottom of the limiting post 10 is fixedly connected to the second movable sleeve 16 by a thin plate 18. When the user uses it... First, remove the disposable sealing strip 7. Then, rotate the anti-theft label cover 2 until the label pointer 8 points to the desired mark 6. Next, press the anti-theft label cover 2 to release the restriction between the bottom of the limiting post 10 and the thin plate 18. Continue pressing the anti-theft label cover 2 until the limiting bead 15 is engaged in the annular groove 11. At this time, the maximum outer diameter of the first movable sleeve 14 is abutted against the conical positioning seat 13. Under the elastic action of the spring 17, the second movable sleeve 16 is pushed to further limit the limiting bead 15. The annular groove 11 is provided with anti-slip texture. The rotation of the limiting post 10 is controlled, thereby locking the limiting post 10 and restricting the movement of the anti-theft label cover 2 fixedly connected to the limiting post 10. That is, the label pointer 8 can only be adjusted once, and after adjustment, others cannot change it. In order to increase the stability of the 2, a locking block 12 is fixedly provided on the bearing plate 9. The locking block 12 matches the bottom of the limiting post 10. The locking block 12 is located in the inner ring of the spring 17 and does not contact the spring 17. When the limiting bead 15 is inserted into the annular groove 11, the limiting post 10 is inserted into the locking block 12.

[0030] As one embodiment of this invention, in order to facilitate the opening and closing of the cover 1, a number of anti-slip grooves 5 are provided on the outer ring of the cover 1.

[0031] Working principle:

[0032] In use, first peel off the disposable sealing strip 7, then rotate the anti-theft label cover 2 until the label pointer 8 points to the desired mark line 6. Then press the anti-theft label cover 2 to release the restriction between the bottom of the limiting post 10 and the thin plate 18. Continue to press the anti-theft label cover 2 until the limiting bead 15 is inserted into the annular groove 11. At this time, the maximum outer diameter of the first movable sleeve 14 is abutted against the conical positioning seat 13. Under the elastic action of the spring 17, the second movable sleeve 16 is pushed to further limit the limiting bead 15. The annular groove 11 has anti-slip texture to restrict the rotation of the limiting post 10, thereby locking the limiting post 10 and restricting the movement of the anti-theft label cover 2 which is fixedly connected to the limiting post 10.
