The bottom cover 3 can be integrally formed or installed at the lower opening of the can body 2. The plastic connecting ring 20 is integrally formed at the upper opening of the can body 2.
[0032] refer to Figure 1 , Figure 2 and Figure 5 The anti-theft cover 1 is an anti-theft cover 1 with a toothed lock, comprising a plastic connecting ring 20, a plastic cover 10 and an anti-theft piece 30. The plastic connecting ring 20 and the plastic cover 10 have a mutually matched screw connection structure so that the plastic cover 10 can be rotated and opened relative to the plastic connecting ring 20. The anti-theft piece 30 is connected to the outer side of the plastic connecting ring 20 through a breakable structure 31.
[0033] refer to Figure 6 In this embodiment, the can body 2 is a plastic can body and is integrally formed with a plastic connecting ring 20. Of course, the plastic connecting ring 20 can also be snap-fitted to the upper opening of the can body 2.
[0034] refer to Figure 1 , Figure 2 and Figure 5The anti-theft component 30 has a second rack 32 with a tooth tip facing upward, and the outer periphery of the plastic cover 10 is surrounded by a first rack 11 with a tooth tip facing downward at least in part. The plastic cover 10 is screwed onto the plastic connecting ring 20 and the first rack 11 is meshed with the second rack 32. The first rack 11 and the second rack 32 have opposite blocking walls 301 in the direction in which the plastic cover 10 and the plastic connecting ring 20 are relatively rotated to open, so as to prevent the plastic cover 10 from rotating and opening relative to the plastic connecting ring 20, that is, the first rack 11 has a blocking wall 301 in the direction in which the plastic cover 10 is opened, and the second rack 32 is in the direction in which the plastic cover 10 and the plastic connecting ring 20 are relatively rotated to open. The connecting ring 20 has a blocking wall 301 in the direction of rotation relative to the plastic cover 10; the first rack 11 and the second rack 32 have relative inclined walls 302 in the direction of relative rotation and closing of the plastic cover 10 and the plastic connecting ring 20, so that when the anti-theft cover 1 can be rotated and closed relative to the plastic connecting ring 20, the inclined wall 302 of the first rack 11 slides relative to the inclined wall 302 of the second rack 32, that is, the first rack 11 has the inclined wall 302 in the direction of closing the plastic cover 10, and the second rack 32 has the inclined wall 302 in the direction of rotation of the plastic connecting ring 20 relative to the plastic cover when the plastic cover 10 is rotated and closed.
[0035] The tooth tips of the first rack 11 and the second rack 32 may be pointed, rounded, or terraced. In this embodiment, the tooth tips of the first rack 11 and the second rack 32 are rounded.
[0036] During assembly, the plastic cover 10 is rotatably mounted on the upper opening of the plastic connecting ring 20. As the plastic cover 10 rotates in the positive direction (rotates in the closing direction, such as Figure 1 As shown by the arrow in the figure, the plastic cover 10 gradually descends to close the plastic connecting ring 20. As the plastic cover 10 descends, the first rack 11 gradually contacts and engages with the second rack 32, and the inclined wall 302 of the first rack 11 slides relative to the inclined wall 302 of the second rack 32 until the plastic cover 10 is tightened relative to the plastic connecting ring 20. After assembly, due to the relative resistance of the blocking wall 301 of the first rack 11 and the blocking wall 302 of the second rack 32, the plastic cover 10 cannot rotate in the reverse direction (rotate in the direction of opening) relative to the plastic connecting ring 20. Figure 5 As shown in FIG. 1 , the plastic cover 10 and the plastic connecting ring 20 maintain a locking relationship. When the plastic cover 10 needs to be opened, as shown in FIG. Figure 5 The anti-theft piece 30 is destroyed to remove the anti-theft piece 30 from the plastic connecting ring 20 , so that the locking between the plastic cover 10 and the plastic connecting ring 20 is released, and the plastic cover 10 can be rotated open relative to the plastic connecting ring 20 .
[0037] In this embodiment, the blocking wall 301 of the second rack 32 is parallel to the central axis (vertical direction) of the anti-theft cover 1, or is tilted downward or tilted upward. When the blocking wall 301 of the second rack 32 is tilted upward, the angle between the blocking wall 301 of the second rack 32 and the central axis (vertical direction) of the anti-theft cover 1 is less than a small angle, such as 15 degrees. The blocking wall 301 of the first rack 11 matches the blocking wall 301 of the second rack 32. The inclined wall 302 of the second rack 32 is tilted upward and preferably has an angle of greater than or equal to 45 degrees and less than or equal to 70 degrees relative to the central axis of the anti-theft cover 1. In this embodiment, the angle of the inclined wall 302 relative to the central axis of the anti-theft cover 1 is 60 degrees + 2 degrees. The inclined wall 302 of the first rack 11 matches the inclined wall 302 of the second rack 32.
