Referring to fig. 1 to 4, an embodiment of the present invention provides a protective cover with an acoustic-magnetic anti-theft tag 1 for protecting canned products, which includes: an acoustic-magnetic antitheft label 1 and a cover body 2 which is entirely transparent and nonmetallic and is used for covering an end part (such as a top end part or a bottom end part) of a canned product; the cover body 2 is provided with a cavity (not shown), the acoustic-magnetic anti-theft tag 1 is arranged in the cavity of the cover body 2, and the bottom surface of the acoustic-magnetic anti-theft tag 1 is substantially perpendicular to the bottom surface of the cover body 2 so that the tag does not obviously shield product information at the bottom of the tank.
Compared with the prior art, the embodiment of the utility model provides a visor that has acoustic magnetic anti-theft tag 1 for protecting canned product is through letting lid 2 is transparent, and lets acoustic magnetic anti-theft tag 1's bottom surface perpendicular to basically lid 2's bottom surface can let client clearly see the commodity information on the canned product of visor fixation back on the canned product like this, and is difficult for discovering the existence of acoustic magnetic anti-theft tag 1 when seeing to the tank bottoms from the bottom of visor generally. Even if the can is seen, the protective cover is firmly buckled at the bottom of the can, so that the label can not be taken away, the anti-theft effect is good, the normal observation of a customer on canned products is not influenced, and the warning effect on potential thieves is realized. In addition, because the cover body 2 is completely transparent, the one-dimensional code or the two-dimensional code on the canned product can enable the mobile phone to successfully scan the code.
It should be noted that the canned product may be a powdered milk can, a coffee can, or the like.
It is understood that the can of the canned product may be a metal can (i.e., a metal canned product), a plastic can (i.e., a plastic canned product), a glass can (i.e., a glass canned product), and the like, and is not limited herein.
Furthermore, it should be noted that the fact that the bottom surface of the acoustic-magnetic anti-theft tag 1 is substantially perpendicular to the bottom surface of the cover 2 may mean that: the included angle between the bottom surface of the acoustic magnetic anti-theft label 1 and the bottom surface of the cover body is 75-90 degrees.
In addition, it is understood that the protective cover may be in the form of a base, a bottom cover, or a protective cover, and is not particularly limited herein.
In the above embodiment, further, referring to fig. 1 to 4, the cover 2 is provided with a window 5 penetrating through the bottom and the top thereof. Therefore, the customer can see the commodity information on the canned product more clearly through the window 5, and the customer can uncover or scrape off the discount code on the canned product through the window 5 conveniently, so that the effect of sales promotion of manufacturers or merchants is achieved.
Of course, the cover 2 may be completely transparent without the window 5.
As a modification of the above solution, referring to fig. 1 to 4, the cover body 2 includes a transparent and annular outer side wall 20, a transparent and annular inner side wall 21 and a transparent bottom plate 22; the outer side wall 20 surrounds the inner side wall 21, and the bottom plate 22 is connected between the bottom of the outer side wall 20 and the bottom of the inner side wall 21; the cavity is formed by the outer side wall 20, the inner side wall 21 and the bottom plate 22, and the window 5 is formed by the inner side wall 21; the top end of the outer side wall 20 has a catch formation for catching the end of the canned product.
