    TECHNICAL FIELD OF THE INVENTION
    The invention relates to a lid of a can containing a food product, said lid being provided with a lever of first class, one end has the shape of a ring and the second extends over a frangible zone of lid, so that by pulling on the ring the second end pushes said frangible zone, which breaks and returns at least partially in the can to allow access to the food product. The invention also relates to a can with a lid according to the invention.
    STATE OF THE PRIOR ART
    [0002] For many years, cans containing alcoholic beverages or not are made of tinplate or aluminum. To facilitate the opening, a ring on the lid allows by pulling it to open a hole to access the drink, tearing a frangible part of the lid. Originally, the ring with the torn part of the lid was thrown anywhere increasing the pollution and especially causing injuries, because the periphery of this part torn off is sharp. To overcome this drawback the manufacturers have fixed, in principle by a rivet, a small first class lever on the cover. One end of the lever includes a ring and the other end extends over a frangible area of the cover. By pulling on the ring, the end extending over the frangible zone pushes the frangible zone which breaks by partially returning into the bobbin and generates a hole allowing access to the drink. No part being torn off, the aforementioned drawbacks are eliminated.
    [0003] Nevertheless, another disadvantage arises. The part that enters the bobbin may be dirty and / or contaminated, unless the user takes the trouble, before opening, to clean the lid. Often the user does not consume the drink by pouring it into a glass or using a straw, but he puts the lid with the hole in contact with his mouth, which increases the risk of contamination. Other preserves of the same type containing solid or liquid food, for example, meat, fish, vegetables, salads, soups, ... are provided on their lid with a lever of first class for roughing an opening and then tear the lid partially or completely, always thanks to a frangible area of the lid which extends over the entire periphery of the lid or at least a large part. In this case too, when pulling on the ring, part of the lid enters the can with the same risk of contamination. Often the user, to pull on the ring presses with his thumb or another finger on the second end of the lever without making sure that thumb is really clean.
    The present invention aims to provide a cover overcoming these risks of contamination of the user.
    STATEMENT OF THE INVENTION
    The lid according to the invention is characterized in that a protective film provided with a tear tab is glued on the entire surface of the lid.
    The advantage of such a cover is that the dirt and / or contamination are only on the protective film that is removed partially before proceeding to the opening of the can.
    Preferably the pulling tab is located on a geometric arc opposite the second end of the first class lever to partially tear said film and have access to the ring of said lever first class. Indeed, the user, to facilitate opening, pulls on the ring with a finger, often the index finger, and press with another finger, often the thumb, on the second end of the lever. However, if the protective film is completely torn off, the user's finger, which is based on the second end of the lever, can contaminate the part of the lid that enters the can. The film is completely torn off after the frangible portion of the lid enters the can.
    BRIEF DESCRIPTION OF THE FIGURES
    The invention will be described in more detail with the aid of the accompanying drawing showing two types of canned foods.<tb> Fig. 1 <SEP> is a plan view of a lid of a can,<tb> fig. 2 <SEP> is a plan view of a lid of a can containing a solid food product,<tb> fig. 3 <SEP> is the same as FIG. 1 with a transparent protective film,<tb> fig. 4 <SEP> is the same as FIG. 2 with a transparent protective film.<tb> fig. <SEP> is a section along line V-V of FIG. 3.
    DETAILED DESCRIPTION OF EMBODIMENTS
    In the accompanying figures, a can (can containing a beverage) and a canister of cylindrical shape are shown but any other geometric shape is possible. The invention is therefore independent of both the shape of the box and the material of which it is made, although in most cases it is tinplate or aluminum.
    In FIG. 1 a cylindrical bobbin 1 is shown closed by a cover 2 of diameter smaller than the diameter of the body of the bobbin. The lid 2 has a swept area 21 towards the inside of the can. On this stamped area a lever first class 22 is fixed by a rivet 24. One end of the lever 22 is provided with a ring 23 and the second end 25 extends over a frangible zone 27 delimited by the thinning the lid along a line 26. When pulling on the ring 23 the second end 25 of the lever 22 pushes the frangible zone 27 which breaks along the line 26 and partially enters the bobbin. As indicated above, the user tends to press with a finger on the second end 25 of the lever to support and facilitate opening.
    In FIG. 3 a transparent protective film 28 is glued on the entire surface of the cover 2. The protective film 28 is provided with a tab 29 for tearing the film just before opening the can as indicated above. The tab 29 is preferably located on a geometric arc opposite the second end 25 of the lever 22. Thus, the user can partially tear the protective film 28 by pulling on the tab 29 to access the ring 23 He pulls with one finger on the ring 23 and presses with another finger on the second end 25 of the lever 22 always protected by the protective film 28. When the part 27 enters the can, it completely pulls off the protective film 28 for access the content.
    In FIG. 2 a can containing a solid food product comprises a cylindrical body 3 closed by a lid 4 of the same diameter. The cover 4 comprises different zones stamped towards the inside of the box, including the zone 41. These zones make it possible to stiffen the cover 4 during its tearing and to facilitate its opening along a frangible line 46 which in principle extends over the whole of its periphery. A lever of first class 42 is fixed on the cover 4 by a rivet 44. One end is provided with a ring 43 and the second end 45 is close to the frangible line 46. When pulling the ring 43 the second end 45 pushes the area of the cover 4 located near the frangible line which breaks and part of this area enters the can. Then, simply continue to pull on the ring 43 to tear the cover 4 over all or part of its periphery along the frangible line 46.
    In FIG. 4 a transparent protective film 48 is glued on the entire surface of the cover 4. The protective film 48 is provided with a tab 49 for partially tearing the protective film just before opening the can as previously indicated . The tab 29 is preferably located in an arc diametrically opposite the second end 25 of the lever 22 The operating instructions are the same as described in relation to FIG. 3.
    We have indicated in the description a transparent film but any film of a thickness vary, (the order of a 0.3-2 mm thick, adhesive film on the inside, flexible and solid), that it is transparent or not, plastic, metallic, metallized, ... similarly the shape and dimensions of the covered surface may vary, the main thing being to cover the part of the lid that will return when opened in the can or can.
    During the manufacture of the can, the protective film will be glued to the lid before the introduction of the lid and the closure of the can.
