Description

Technical Field

[0001] This utility model relates to the field of anti-theft label technology, specifically an anti-theft label for bottle and can products. Background Technology

[0002] Anti-theft tags for bottled and jarred goods typically consist of a steel wire wrapped around the radial side of the bottle or jar, secured by a locking mechanism. This design relies on the clamping force of the wire against the side of the bottle or jar for fixation. However, due to the geometric characteristics of bottles and jars—smooth, continuous surfaces without significant protrusions or depressions—the wire struggles to anchor effectively. Under external forces (such as pulling, twisting, or sliding), the anti-theft tag easily slips off the opening or bottom of the bottle or jar. This is because the friction between the wire and the smooth curved surface is insufficient, and the locking connection point often becomes a mechanical weakness, unable to resist axial or lateral detachment forces.

[0003] In addition, the installation of such anti-theft tags usually requires special tools to tighten and lock them. If they are too tight, they can easily damage the product packaging; if they are too loose, they can easily fall off.

[0004] Therefore, existing technologies suffer from insufficient reliability in fixing anti-theft tags to bottle and can products, and there is an urgent need for an anti-theft tag structure that can adapt to smooth cylindrical surfaces, resist external force detachment, and is easy to install. Utility Model Content

[0005] To address the technical problems in the background art, this utility model discloses an anti-theft label for bottle and can products.

[0006] This utility model provides an anti-theft tag for bottle and can products, including a bottom and a lid with openings at opposite ends; The bottom of the cylinder is equipped with fixed lower retaining teeth; The cylinder cap is equipped with upper locking teeth that achieve elastic connection through a compression spring; When locked, the bottom and the lid move towards each other, causing the lower and upper locking teeth to engage. The upper end of the bottle or can abuts the bottom of the lid, and the lower end abuts the bottom of the bottom.

[0007] Directly attaching the cap to the bottom of the tube would cover the product, preventing it from being displayed. Therefore, a further improvement is made: a locking block extending towards the cap is provided at one radial end of the tube bottom, with a lower locking tooth positioned within the block; a sleeve fitting the locking block is provided at one radial end of the cap, with an upper locking tooth positioned within the sleeve. This arrangement ensures that the tube bottom only covers the bottom of the product, and the cap only covers the top, creating a gap between the tube bottom and cap. Product information can then be displayed unobstructed between these two points.

[0008] To improve the connection strength between the cylinder cover and the cylinder bottom, a further design is made: the outer wall of the locking block and the inner wall of the sleeve are fitted together.

[0009] If the locking block and sleeve are circular, the cap and bottom of the sleeve are prone to radial relative rotation, which affects the positional stability of the cap and bottom of the sleeve and also affects the anti-theft effect of the anti-theft tag. Based on this, a further improvement is that the locking block and sleeve are not perfectly circular.

[0010] Since bottled and canned goods vary in height, to make this invention applicable to goods of different heights, a further design is implemented: multiple lower locking teeth are provided; the lengths of the locking block and sleeve are configured such that when the lower locking tooth engages with the upper locking tooth, the sleeve engages with the locking block. With this configuration, by engaging different lower locking teeth with the upper locking tooth, the distance between the cap and the bottom of the can can be adjusted, making this invention applicable to goods of different heights.

[0011] Since the bottom and cap are separate parts, they are easy to lose. Therefore, a further improvement is made: the bottom and cap are connected by a hanging rope.

[0012] Unlocking requires manually separating the cap from the bottom of the cylinder, which is cumbersome. Therefore, a further improvement is made: a spring connects the bottom and cap, replacing the hanging rope. With this design, the spring is in a deformed state when locked; when the upper and lower locking teeth disengage, the spring's elasticity automatically drives the cap to separate from the bottom.

[0013] Placing the spring inside the anti-theft tag not only makes its structure more complex and increases manufacturing costs, but also makes spring installation more difficult. Therefore, a further improvement involves placing the spring outside the bottom and top of the tube; its axial projection from the bottom of the tube is offset from the locking block and sleeve. This offset arrangement also reduces the space occupied by the anti-theft tag.

[0014] The specific connection structure of the spring is as follows: the two ends of the spring are respectively led out as a first connecting rod and a second connecting rod, which are inclined and form a V shape with their openings facing the locking block; the first connecting rod is connected to the sleeve; the second connecting rod is connected to the locking block.

[0015] Because bottled and jar products have a small top diameter and a large bottom diameter, a cap that matches the top diameter of the bottle or jar is typically used to improve the stability of the connection between the anti-theft tag and the product. To accommodate different products, multiple different models of anti-theft tags are usually used, which is costly. Therefore, a further improvement is made: the end of the first connecting rod is provided with an external thread, which is locked by an upper nut connected to the thread, thus fixing the first connecting rod and the sleeve. This design allows the cap and spring to be detachably connected. When the top diameter of the product changes, only a cap of a different diameter needs to be replaced, thereby reducing costs.

[0016] The beneficial effects of this utility model are: 1. By engaging the upper and lower locking teeth, the bottom of the cylinder and the cap are locked together, thus confining the bottle or can product between the bottom and the cap and achieving a locking mechanism. Compared to the traditional steel wire locking mechanism that relies on clamping force, this invention can resist external forces such as axial pulling, torsion, or sliding, preventing the label from slipping off the bottle or can opening or bottom. It is especially suitable for addressing the problem of difficulty in anchoring smooth cylindrical surfaces.

[0017] 2. Locking can be completed by moving the bottom and lid of the cylinder towards each other, which is simple and convenient to operate; moreover, the contact area between the bottom of the cylinder and the bottom of the product, and between the lid and the top of the product, is large, so that the product will not be damaged when pressure is generated between them.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Example 1: like Figure 1-6 As shown, this utility model discloses an anti-theft tag for bottle and can products, including a cylindrical bottom 1 with openings 43 at opposite ends and a cylindrical cap 2. The cylindrical bottom 1 is used to fit over the bottom of the bottle or can product, and the cylindrical cap 2 is used to fit over the top of the bottle or can product.

[0022] by Figure 3 For reference, a locking block 5 extending upwards is provided at one radial end of the bottom of the cylinder 1. Multiple vertically evenly arranged lower locking teeth 3 are provided on the locking block 5, pointing towards the lower right. A sleeve 6 extending downwards is provided at one radial end of the cover 2 for engaging the locking block 5. Multiple vertically evenly arranged upper locking teeth 4 are provided inside the sleeve 6, pointing towards the upper left. The number of upper locking teeth 4 is less than the number of lower locking teeth 3, and the inclination angles of the upper locking teeth 4 and lower locking teeth 3 are the same.

[0023] The upper locking tooth 4 is elastically connected to the sleeve 6 via a compression spring 12. The specific connection structure is as follows: the right side of the sleeve 6 is provided with a protrusion and the left side has an opening 43, forming a mounting cylinder 10. The right side of the upper locking tooth 4 is provided with an integrally formed, hollow insert 41, which is inserted into the mounting cylinder 10 to achieve the movement limit of the upper locking tooth 4.

[0024] One end of the drive rod 11, which can be attracted by a magnet, engages with the upper retaining tooth 4, and the other end is inserted into the insert post 41. A compression spring 12 is sleeved on the drive rod 11, with one end abutting against the upper retaining tooth 4 and the other end abutting against the bottom of the mounting cylinder 10. The specific engaging structure of the drive rod 11 is as follows: Figure 7-10As shown, a radially penetrating groove 42 is provided at the connection between the upper locking tooth 4 and the insertion post 41. An opening 43 connecting to the groove 42 is also provided on one radial side of the insertion post 41. An inwardly protruding protrusion is provided at the connection between the opening 43 and the groove 42 on the insertion post 41. A radially protruding locking plate 13 is provided at the left end of the drive rod 11. During installation, the drive rod 11 is inserted into the insertion post 41 from the opening 43, and the locking plate 13 engages with the slot. The protrusions are arranged in three spaced-apart blocks, each with an inner arc surface 44, which are concentric and have a diameter equal to the outer diameter of the drive rod 11. During installation, the drive rod 11 fits against the arc surface 44 to improve its stability. One of the protrusions is a bottom protrusion 45, which is opposite to the opening 43; the other two protrusions are side protrusions 46, arranged symmetrically with respect to the center line of the opening 43. The arc surface 44 on the side protrusion 46 is connected to a straight surface 47 and an inclined surface 48 in sequence. The two straight surfaces 47 are parallel, and the distance between them is slightly smaller than the diameter of the arc surface, so that the arc surface 44 can limit the movement of the drive rod 11. The two inclined surfaces 48 form a flared shape, which can guide the installation of the drive rod 11.

[0025] When locked, the cylinder cover 2 moves towards the cylinder bottom 1; when the upper locking tooth 4 contacts the lower locking tooth 3, the upper locking tooth 4 moves to the right under the guidance of its inclined surface 48; when its guiding inclined surface 48 disengages, the compression spring 12 drives the upper locking tooth 4 to move to the left and engage with the lower locking tooth 3; thus, the upper locking tooth 4 and the lower locking tooth 3 are automatically engaged. When unlocked, when the magnet is placed at the right end of the mounting cylinder 10, the drive rod 11 is attracted by the magnet, moves to the right, and drives the upper locking tooth 4 to disengage from the lower locking tooth 3. At this time, the compression spring 12 is in a compressed state; when the magnet is removed, the upper locking tooth 4 returns to its original position under the elastic force of the compression spring 12. With this setting, by engaging different lower locking teeth 3 with the upper locking tooth 4, the distance between the cylinder cover 2 and the cylinder bottom 1 can be adjusted, making this utility model applicable to products of different heights.

[0026] Furthermore, when the upper locking tooth 4 and the lower locking tooth 3 engage, the sleeve 6 always engages with the locking block 5 to improve the stability of the connection structure between the cylinder cover 2 and the cylinder bottom 1. To prevent relative radial rotation between the cylinder cover 2 and the cylinder bottom 1, the locking block 5 and the sleeve 6 are designed to be non-circular. In this embodiment, the locking block 5 and the sleeve 6 are rectangular; in other embodiments, they can also be hexagonal or arc-shaped, as long as the sleeve 6 cannot rotate when engaging the locking block 5.

[0027] The sleeve 6 and the locking block 5 are designed so that the bottom 1 of the sleeve only covers the bottom of the product, and the lid 2 only covers the top of the product, with a gap between the bottom 1 and the lid 2; the product information can be located exactly between the bottom 1 and the lid 2, allowing for unobstructed display.

[0028] The bottom 1 and the cover 2 are connected by a hanging rope, so that the bottom 1 and the cover 2 are always connected and are not easily lost.

[0029] The locking process is as follows: first, place the bottom of the cylinder 1 horizontally on the workbench, then place the bottle or can product with its bottom facing down inside the bottom of the cylinder 1; finally, move the cylinder cap 2 downwards so that the sleeve 6 engages with the locking block 5 and the upper locking tooth 4 engages with the lower locking tooth 3, until the bottom of the cylinder cap 2 touches the bottom of the bottle or can product.

[0030] The unlocking process is as follows: Place the magnet on the right end of the mounting cylinder 10. At this time, the upper locking tooth 4 moves to the right and disengages from the lower locking tooth 3. Then pull the cylinder cover 2 upward until the cylinder cover 2 disengages from the cylinder bottom 1, thus completing the unlocking.

[0031] Compared to existing technologies, the advantages of this embodiment are: 1. By engaging the lower locking teeth with the upper locking teeth 4, the bottom 1 and the lid 2 are locked together, thus confining the bottle-type goods between the bottom 1 and the lid 2 and achieving locking. Compared to traditional steel wire locking that relies on clamping force, this invention can resist external forces such as axial pulling, torsion, or sliding, preventing the label from slipping off the bottle mouth or bottom, and is especially suitable for the problem of difficulty in anchoring smooth cylindrical surfaces. 2. Locking can be completed by moving the bottom 1 and the lid 2 towards each other, which is simple and convenient to operate; moreover, the contact area between the bottom 1 and the bottom of the goods, and between the lid 2 and the top of the goods is large, so that when pressure is generated between them, it will not damage the goods.

[0032] Example 2: Compared with Embodiment 1, the difference is that a spring 7 is connected between the bottom 1 and the cover 2, replacing the hanging rope. With this configuration, when locked, the spring 7 is in a deformed state; when the upper locking tooth 4 disengages from the lower locking tooth 3, the elastic force of the spring 7 drives the cover 2 to automatically separate from the bottom 1.

[0033] The specific installation structure of spring 7 is as follows: spring 7 is set outside the cylinder bottom 1 and cylinder cover 2, with its two ends extending obliquely to the same side, forming a V-shape, with the opening 43 facing the locking block 5. First connecting rod 71 and second connecting rod 72 are connected; first connecting rod 71 is connected to sleeve 6; second connecting rod 72 is connected to locking block 5. The ends of first connecting rod 71 and second connecting rod 72 are both provided with external threads, and are respectively threaded to upper nut 8 and lower nut 9. The end of first connecting rod 71 is inserted into sleeve 6 and locked and fixed by upper nut 8; second connecting rod 72 is inserted into locking block 5 and locked and fixed by lower nut 9.

[0034] The above-mentioned design facilitates the assembly and disassembly of the spring 7. Furthermore, since bottled and jar products typically have a small top diameter and a large bottom diameter, a cap 2 matching the top diameter of the bottle or jar is generally used to improve the stability of the connection between the anti-theft tag and the product. In this embodiment, the detachable connection between the first connecting rod 71 and the sleeve 6 allows for easy replacement of the cap 2 with a different diameter when the top diameter of the product changes, thus reducing costs.

[0035] Furthermore, the arrangement of the first link 71 and the second link 72 ensures that the spring 7, the locking block 5, and the sleeve 6 are staggered in the axial projection of the bottom of the cylinder 1, thereby reducing the space occupied by the anti-theft tag.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
